Introduction
~~~~~~~~~~~~
Welcome to the most powerful, versatile, and user-friendly music player
ever created on the Amiga! As you will see, MultiPlayer has almost all the
features you've seen in other music players, plus a great number that have
never been implemented before in a music player.
If you want to get full benefit from MultiPlayer you should at least
scan through this whole documentation. However, it is very easy to use, so
feel free to take it for a test drive first. If you're upgrading from a
previous version of MultiPlayer, make sure you look at the History section
near the end of this document to see what's new.
One of the goals of MultiPlayer is to be as system-friendly as
possible. It multitasks well, it doesn't interfere with high-priority
interrupts such as serial port interrupts, and it properly allocates audio
channels so that the music doesn't conflict with other programs. It takes
full advantage of (and requires) Kickstart 2.0, and it isn't prone to
"lose" notes on fast processors like most other players are.
Another goal of MultiPlayer is to support a very diverse array of music
formats. MultiPlayer currently supports over twenty different common
module formats, plus some special ones. See 'Supported Formats' near the
end of this document for a list of the module types MultiPlayer can play.
(Not all of MultiPlayer's features are available with every module format,
but MultiPlayer will at least play each format on the list.)
Updates and Registration
~~~~~~~~~~~~~~~~~~~~~~~~
As stated above, MultiPlayer is free software, distributed under the
GNU General Public License. Therefore you may distribute it and its source
code freely as long as you don't deprive others of that right. (See the
file COPYING-2 for all the details.)
If you use MultiPlayer often, you may want to register with me to get
telephone and E-mail support, cheap and easy updates, and other benefits.
Registration is only $15 (must be in US currency). This is not a "do this
or your conscience or haunt you for the rest of your life" request; I'm
only asking you to register if you want the extra benefits (listed below)
that you will get by registering. If you don't want them, then enjoy the
program, but don't expect anything more from me.
Unregistered users may order the latest version of MultiPlayer by sending
$5 (US currency ONLY) to my address listed at the bottom of this document.
I will send you full binaries and source code, including any non-commercial
utilities required to compile it (not including compiler and other very
large programs).
Registered users get a little more flexibility. To order the latest
version by E-mail, simply send either $2 (bills are fine) or two disks to
my address below, whichever is more convenient for you. Registered users
may also pre-order future updates: simply specify the latest version you
already have along with your $2 or two disk, and I will send you the next
version after that, as soon as it is released. Registered users that don't
pre-order and aren't on the Internet will receive announcements of major
new updates of MultiPlayer (probably not every version, but every one that
adds a significant number of new features). Registered users on the Internet
of course get announcements every version, and may request both binaries and
sources directly from me by E-mail.
Registered users are encouraged to keep in contact with me by mail,
phone, or E-mail; whichever is most convenient for you. I enjoy chatting
with users, and while I don't have a great deal of time to work on
MultiPlayer, I do try to implement all the requested features I have time
for. (Note that your particular most-wanted features are likely to be
implemented sooner if you keep pestering me about them. :-) ) If you're
going to call me by phone, note that I live on the west coast of the US,
and you are most likely to get through to me in the early evening. Mail
and E-mail are of course welcome any time.
I will NOT go out of my way to satisfy the wishes of unregistered
users. $15 is nothing compared to the registration fees of many Shareware
programs of much lower quality. If you don't think the above benefits are
worth $15, then don't register - but don't expect me to provide any kind of
support.
If you have a bug fix or enhancement you've made to MultiPlayer and
would like included in the official distribution, send it to me and I'll
probably (no promises) incorporate it if it's reasonably clean, isn't
likely to break lots of other things, seems at least slightly useful, is
understandable, etc. If your added or modified code is more than about a
screen or so long, I'll need a signed (paper) document releasing all rights
to the code to me, for distribution under the General Public License. (I
hate legal details, but I would hate even more getting into stupid
squabbles and/or lawsuits due to an oversight of these legal details.) If
your additions are quite extensive (i.e. a new module or something like
that) and you work for a computer-related company of some kind, I may get
nervous and require a signed disclaimer from your employer as well.

General Usage
~~~~~~~~~~~~~
To start MultiPlayer, just type 'player' from the CLI or click on the
icon from the Workbench and it will present the ASL filerequester to select
a module from. Note that you can select multiple modules at a time (as
many as you want). If you run MultiPlayer from the CLI, it automatically
detaches itself, so there is no need to Run it. (You can turn this feature
off, however.) You can also start modules playing immediately when
MultiPlayer starts up. See the section on 'Startup Options' for more
information on starting MultiPlayer.
While MultiPlayer is running there is normally a small window in the
title bar displaying the name of the module that is currently playing (or
just "MultiPlayer" if nothing is loaded). You can click the close gadget
to stop the music and terminate MultiPlayer. (You can change this behavior
in the Preferences window so that closing the main window simply hides the
user interface, leaving MultiPlayer active in the background.) The main
MultiPlayer window has a zoom gadget near its right end. If you click it,
you will see a control panel that allows you to load different modules and
gives access to some of MultiPlayer's more advanced features.
If you have the xpkmaster.library (a freeware compression "supervisor"
standard mostly by Dominik Mueller, Christian Schneider, and myself)
installed in your system, MultiPlayer can automatically unpack modules that
are packed using any format it can understand. (This includes PowerPacker
format, if you have the powerpacker.library installed as well.)
If you start getting shaky when you see MultiPlayer's size (>90K),
don't worry - thanks to a custom memory management and overlay system
called Bovs, MultiPlayer uses only the memory it needs to do its job. All
of the module players are loaded only when needed, and any players not
currently in use are unloaded on demand if the system runs out of memory.
The parts of the program used to control MultiPlayer's various windows are
also only loaded when they are needed (when the respective windows are
open) and are freed as necessary. Thus, generally only a small fraction of
the program code is loaded at any one time.
If you have tons of memory and don't want overlays, the registered
release comes with a separate version of MultiPlayer ("Player.nov") that
runs without overlays (like a normal program). It generally uses about 50K
more memory than the overlaid version does, but it can be compressed with
PowerPacker or Imploder if you're short on disk space. (Imploder *should*
be able to compress the overlaid version of MultiPlayer, but it won't - I
haven't figured out why.)
For all you hackers (used in the positive meaning) that like to rip out
every form of music imaginable, when you come across some obscure module
format that nothing understands, don't despair. There are several special
formats built into MultiPlayer that you can use to easily interface it to
any kind of module. All you need is the module, some player code for the
module (if the module doesn't already have embedded player code), and a
little assembly language coding. Details on all three formats are in the
separate file 'GMOD.doc' (in the Programmers directory of the official
MultiPlayer distribution). If you are the author of a music composer
program, you should also read this document and consider supporting the
GMOD embedded-player module format in your program. (It's not a music
storage standard - it's more like a music playing standard - see the
document for details.)
Control Panel
~~~~~~~~~~~~~
The main MultiPlayer window normally sits quietly in the title bar. (If
you don't like it there, move it somewhere else and save the preferences -
it'll stay put wherever you want it.) However, if you click the zoom
gadget, it will become a control panel. The F1 key also performs this
function. If you have a 3-button mouse, the middle button will act the same
as the zoom gadget. This panel displays a few pieces of information about
the module currently playing, and has some buttons you can use to control
MultiPlayer.
The MultiPlayer control panel is an AppWindow, so you can play modules
by simply dropping their Workbench icons into the MultiPlayer window. When
you do, the new module (or several modules, if you extended-select them)
replaces the current program, and MultiPlayer starts playing the first
module immediately. This works basically like selecting modules with the
New button.
Module box
This box displays the filename of the module currently loaded
(essentially the same as what is displayed in the title bar). Any 'mod.'
prefixes for Soundtracker/Noisetracker modules will not be displayed.
Type box
Displays the type of the loaded module (as MultiPlayer sees it).
Simple enough?
Author box
Displays the name of the person who wrote this module, if MultiPlayer
can glean this information from the module. Most current module formats
don't have direct facilities for identifying the author - in this case, the
box will just display 'Unknown'. Soundtracker/Noisetracker modules often
have author names embedded in the instrument list - in this case,
MultiPlayer will try to make a good guess by searching for keywords such as
'by'. (If it screws up for some reason, you can always type the module in
hex to find out for sure.) MED modules have somewhat better support, but
they still don't have a convenient 'author' field - just a catch-all
'annotation' field, which MultiPlayer processes much the same way as with
Soundtracker modules. GMOD modules are the only types I know of that
directly support author identification, but they are at the moment few and
far between. (Let's get with it, OK? Don't all the wonderful musicians
want to be recognized?)
Song gadget
This gadget serves two purposes. First, it displays the name of the
currently loaded module or song as recorded in the module itself. For
example, with Soundtracker/Noisetracker modules this gadget will display
the song name as recorded in the first 20 bytes of the file. Many module
formats don't have built-in name fields - in this case, the box will just
display 'Unknown.'
For most types of modules, which support only one song per module, this
gadget will serve no purpose other than displaying the song name - clicking
on it will do nothing. However, some module formats (such as GMODs) allow
several independent songs to be contained in a single module (for example,
to save memory by using the same instruments on several songs). In that
case, this gadget will cycle through the available songs in the module.
You can also change songs using the left and right arrow keys.
Volume slider
This slider controls the volume of the currently playing module.
Minimum volume is all the way to the left; maximum is all the way to the
right. This feature doesn't work with all types of modules, but it works
with the most popular types.
The current master volume, balance, and speed settings are saved with
MultiPlayer's Preferences, so when MultiPlayer starts up they will be set
to whatever they were set to last time you saved MultiPlayer's preferences.
Balance slider
This slider adjusts the balance by scaling the left and right volumes
separately. When the slider is all the way to the left, only the left
channels will be played; when it is all the way to the right, only the
right channels will be played. Normally it's in the center, where both
sides play with equal volume. Like the volume control, this feature
doesn't work with every type of module MultiPlayer supports.
Balance Reset button ('=')
The small button labeled with an equals sign resets (equalizes) the
Balance slider, setting it back to the center position.
Speed slider
This slider can be used to fast-forward through a module. The normal
position is to the far left; moving the slider right will speed it up. This
gadget isn't meant for controlling the module's normal playing speed - for
that, use the speed control in the Settings window.
Jump buttons ('<<' and '>>')
For module types that support sequence jump, these buttons will
instantly jump one sequence forward or backward in the module.
New button
This button displays the file requester and lets you select any number
of modules. The new list of modules replaces the current program, if there
was one. The first module in the list (or a random module, if you have
selected random playing) will be started. If you select a directory but
don't select a file (leave the "File" string gadget blank), MultiPlayer
scans the directory and adds everything in that directory to the program.
Play button
Starts (or restarts) the currently loaded module at the beginning.
Cont button
Starts or continues playing a module that was previously stopped but
not unloaded. If the module type supports the continue feature, the module
will continue playing where it left off. Otherwise it will start again
from the beginning. If you have selected the 'Fade...' checkbox in
Preferences, and the module type supports volume control, the music will
fade in gradually instead of just starting instantly.
Stop button
Stops the current module without unloading it. Audio channels and
interrupts are freed while a module is stopped, so you don't have to exit
MultiPlayer completely if you want to run some other program that needs the
audio hardware. If you have selected the 'Fade...' checkbox in
Preferences, and the module type supports volume control, the music will
fade out gradually instead of stopping instantly. If the module type
supports restart, you can restart it where it left off by pressing the Play
button.
Eject button
Stops and unloads the currently loaded module, and frees all memory and
other resources that the module was using.
Prev button
Loads and plays the previous module in the program list. If you have
selected random play, this button simply loads another module in the list,
at random. This button does the same thing as pressing the up arrow key in
the MultiPlayer window.
Next button
Loads and plays the next module in the current program list. If you
have selected random play, this button does basically the same thing as the
Prev button - picks another module at random. This is the same as pressing
the down arrow key in the MultiPlayer window.
Program, Prefs, Settings, and Info buttons
These buttons toggle on or off some of MultiPlayer's other
commonly-used windows. They can also be controlled with the functions keys
F2-F5 (respectively).
Program Window
~~~~~~~~~~~~~~
The program window displays a list of all the modules in the current
module 'program'. You can select modules from the list to load and play
immediately by simply double-clicking on their names. You can also build
and rearrange your program using this window. You get this window by
pressing the 'Program' button on the main window's control panel, or by
pressing the F2 keys in the MultiPlayer window, or by simply clicking the
right mouse button while any of MultiPlayer's windows are active. Note
that this window doesn't cause the main control panel to "freeze" - you can
still watch and use it while this window is open. In fact, all of
MultiPlayer's windows (even the file requester) work this way. (I'm tired
of Macinsquash-like modal requesters and such that only let you do one
thing at a time.)
Depending on the play mode selected in the Preferences window, when one
module is finished, another module will be automatically loaded and played.
(This only applies on modules that can detect repeat - most do, but on
those that don't, unless you manually set an end time in the Settings
window, the module will just play forever until you explicitly tell
MultiPlayer to go to the next module.) With random play, a different
module will be randomly chosen. There is no limit to the number of modules
you can have in a program, and modules in the program can be located in
many different directories - MultiPlayer will remember the location of each
module.
The Program window is an AppWindow, so you can add modules by simply
dropping their icons into this window. This window works slightly
differently from the main Multiplayer window, however. When you drop icons
into this window, the behavior is the same as if you had selected the
modules with the 'Add' button: The new modules are added to the end of the
current program list (instead of replacing the current program), and
whatever is currently playing remains unaffected.
Besides the module listing, this window contains several buttons that
allow you to manipulate the module list. These are described below:
Play button
This button does basically the same thing as double-clicking on a
module name in the program list. It simply loads and starts playing the
currently selected module.
Current button
Pressing this button will set the currently selected module to the
currently playing module.
Add button
This button works much the same way as the 'New' button on the main
window - it brings up the file requester and allows you to select modules.
However, it doesn't cause the previous program to be cleared when you
finish, and it doesn't start playing a new module immediately. If you
select a directory without selecting a filename, MultiPlayer will scan that
directory and add all the files in it to the program.
Del button
This button deletes the currently selected module in the program list.
If this module is currently playing, it doesn't stop the module immediately
- the module continues playing until you select a different module. The
next module in the program will immediately become the currently selected
module, so you can delete a range of modules by repeatedly clicking the Del
button.
Top, Up, Down, and Bot buttons
These buttons allow you to rearrange the modules in the program. They
work on the currently selected module, and their meanings should be
reasonably obvious.
Load button
Brings up the file requester so you can load a previously saved program
from disk. The newly loaded program will replace the current program.
Note that you can also load saved programs from the regular module
requester - programs are recognized just like modules, and programs
selected this way will automatically be loaded and run. (You could even
put the name of another program file at the bottom of the first one, and
chain programs together!)
Save button
Brings up the file requester and lets you save the current program to a
disk file. You can then load it again later through the Load gadget or
using any method normally used to select modules - the file requester,
Workbench extended-select when starting MultiPlayer, or CLI arguments.
(See the 'Startup' for details on starting MultiPlayer.)
Clear button
Clears the entire current program list. As with the 'Del' button, it
does not stop any currently playing module.
Sort button
Sorts the entire current program list alphabetically. Handy if you
like to use random play (and thus don't really care about the play order)
and you'd like a nice neat module listing.
Program, Prefs, Settings, and Info buttons
These buttons toggle on or off some of MultiPlayer's other
commonly-used windows. They can also be controlled with the functions keys
F2-F5 (respectively).
If you want to create or modify saved program files yourself, just take
a look at one of the files MultiPlayer generates - it's a simple text file.
Lines starting with 'DIR' denote changes of directory - all filenames after
that until another 'DIR' keyword will be looked for in that directory.
Lines that start with a tab character (make sure they remain tab
characters, and don't get converted to spaces!) contain the settings
information for the module on the previous line. I won't explain the
format exactly, but it shouldn't be too hard for you to figure out if you
want to. (You can also look at the source code...)
Preferences Window
~~~~~~~~~~~~~~~~~~
MultiPlayer's built-in Preferences window can be opened by clicking on
the 'Prefs' button in the main or Program window, or by pressing F3 in any
window. It contains a few options which you can use to tailor MultiPlayer
to your own preferences. The gadgets are described below:
Font buttons and displays
These two buttons allow you to choose the font used for displaying the
gadgets and other imagery used in MultiPlayer's windows. Pressing either
button brings up a standard ASL font requester (which is asynchronous, of
course - it doesn't freeze up MultiPlayer while it's displayed). The text
and number gadgets beside each button show the currently selected font.
The Main font is the font used to display almost all of MultiPlayer's
gadgetry: essentially everything except the ListView gadgets in the Program
window and the Information window. For those, the List font is used
instead. The Main font can be any font you like, but the List font must be
a fixed-width font. For the window title bars, the screen's default is
used. (For the Workbench screen, this is selected by the System Text
setting in the Font Preferences program.)
Play gadget
Use this gadget to tell MultiPlayer what to do when it gets to the end
of one module. When 'In sequence' is selected, entire program is played,
in order, one module after another, and the sequence starts over at the
beginning after the last module is played. If you select 'Through sequence
once', the entire sequence is played only once, then the player stops. In
random play, a module plays once and then another is randomly selected. In
'once' mode, the song is played only once, then is ejected and MultiPlayer
becomes idle. In 'over and over' mode, anything you select is played
forever until you tell MultiPlayer to start a different module. (In these
last two modes, you can still use the 'Next' and 'Prev' buttons in the main
window to change modules; MultiPlayer just doesn't change by itself.)
Show gadget
This cycle gadget allows you to select the type of display you want to
appear in the main window's title bar while a module is playing. In Clock
mode, a clock appears displaying the amount of time this module has been
playing in minutes and seconds. In Sequence mode (this has no relation to
the 'in sequence' mode in the 'Play' gadget), on NoiseTracker or similar
modules that play sequences of blocks, the current sequence number and the
number of sequences in the song is displayed. (On modules that don't
support this, the clock is displayed instead.) You can tell MultiPlayer to
display the current sequence number either starting from 0 and ending at
length-1, as most tracker programs display sequence numbers, or starting
from 1 and ending at (length), which is the more 'natural' way of counting.
Selecting the 'Nothing' option in this gadget will leave you with a clean,
simple, unadulterated title bar.
Hot key string gadget
By default, this string gadget is empty and MultiPlayer behaves like a
normal application. However, you can enter a Commodities-style hotkey name
into this gadget. (Make sure you press Return in the gadget after changing
the string!) MultiPlayer will then activate that key as a hot key which
you can use to open the main MultiPlayer control panel at any time. When a
hot key is active, clicking the control panel's close gadget closes all of
MultiPlayer's windows, but does not terminate MultiPlayer or stop playing
music. You can use this too keep MultiPlayer hidden in the background,
without using any screen space at all.
Spectrogram, Note Scroller, StereoScope, and QuadraScope checkboxes
Use these gadgets to toggle MultiPlayer's various "flashy windows" on
and off. These windows are described in detail later. They can also be
toggled with the F6-F9 keys (respectively).
Fade... checkbox
If this checkbox is activated, whenever you press the 'Play' or 'Stop'
gadgets in the main control panel (or press the spacebar), the music
gradually fades in and out rather than abruptly starting or stopping.
This will only happen on modules that support volume control.
Continue program on error checkbox
If this is selected, if MultiPlayer encounters an error while trying to
load or play a module in the program, instead of simply stopping dead, it
moves on to the next program in the list, as requested with the Play gadget.
Save program with prefs checkbox
If this checkbox is activated, MultiPlayer does two things differently
than it normally does. First, when you save the preferences, not only are
the preferences saved as usual, but the currently loaded program is also
saved in ENV: and ENVARC: in a file called "MultiPlayerProgram". (It saves
identical files into both directories.) Second, when MultiPlayer starts
up, if it sees that you have this option set, and you haven't specified any
other modules or programs in the startup options, it automatically loads
this program, without starting it. This way, if you generally only keep
one program around, this option provides an easy way to always load it
automatically without worrying about any startup options or anything. Even
if you have this option selected, you can still load and save other
programs normally through the Program window.
Nasty Audio checkbox
If this option is turned on, MultiPlayer always allocates audio
channels the very highest priority possible, so that no other
(system-friendly) programs can grab the audio channels and play beeps or
speech or other noises on top of the music. It also prevents some problems
with certain ill-behaved programs (especially terminal programs) that
allocate one or two audio channels on startup and never free them until
they exit, even though they aren't using them the whole time. Without this
option set, MultiPlayer will typically "be nice" and let the program keep
its channels, and only play music out the other channels - probably not
quite what you wanted. Setting Nasty Audio allows MultiPlayer to grab
those channels.
Icon checkboxes
If one of these is activated, MultiPlayer puts an icon on the Workbench
screen which you can drop modules and directories into. Dropping modules
onto the 'Play' icon erases the old program and starts playing the new
modules immediately. Dropping modules onto the 'Add' icon simply adds the
new files to the end of the current program, without affecting any module
currently playing. These icons will remain on the Workbench even if all of
MultiPlayer's windows are closed, or if MultiPlayer's windows are on a
different screen. Double-clicking on the icon itself will pop up
MultiPlayer.
This feature works only if MultiPlayer can find its own icon on
startup. You can ensure this by starting MultiPlayer from the Workbench,
or by naming the executable "Player" and having it in the current directory
when you run MultiPlayer from the CLI.
Save button
Saves the current preferences to the disk file ENV:MultiPlayerPrefs, as
well as to the same file in ENVARC:. (With a preferences window as simple
as this, I see no real need for separate 'Save' and 'Save Default'
options.) If the "Keep..." option is enabled, the current program will
also be saved to both ENV: and ENVARC:, as MultiPlayerProgram.
The preferences saved include, as well as the current settings of the
above two gadgets, the positions of all the MultiPlayer windows, including
the file and font requesters. The next time you run MultiPlayer, the
windows will pop up wherever they were when you saved the preferences. (If
you open an ASL file or font requester and change its size or position, you
must close it before saving the preferences, if you want its new position
and size to be saved. Nag Commodore about this misfeature, which stems
from a lack of asynchronous functionality in the asl.library.)
Close button
Does exactly the same thing as the close gadget on the window does -
closes the Preferences window. It does NOT cause the new preferences to be
activated, as you might expect, because they are already activated:
anything you select gets activated the moment you select it. (None of
those exclusive Macie dialog boxes, please.) There is no 'Cancel' gadget
because I figure it's not too difficult to change back any buttons you
accidentally hit.
Settings Window
~~~~~~~~~~~~~~~
MultiPlayer's Settings window serves a function very similar to the
Preferences window. However, there is an important difference. Instead of
storing settings that apply to MultiPlayer as a whole, it is used to select
options that pertain to individual modules in the program list. To get it,
click the 'Settings' button in the program window, or press F4 in any of
MultiPlayer's windows.
The Settings window contains a number of gadgets which control how the
currently selected module (not necessarily the currently playing module) is
to be played. MultiPlayer stores separate settings for each module on the
program list. When you save the program, the settings for each module are
saved with it. Not all of the settings are applicable to every type of
module, so some settings gadgets will be disabled for certain modules.
Module box
This text box displays the name of the currently selected module (the
same as the name displayed under the program list gadget in the Program
window). This is not necessarily the module that is currently playing -
you can edit the settings for one module while you play another (or while
you're not playing any module).
Volume, Balance, and Speed gadgets
The gadgets in these two rows complement the corresponding gadgets in
the control panel. While the controls in the main window control whatever
module is currently playing, these gadgets control the individual modules
in the program. For example, when you play a given module, the volume at
which it plays is determined by both the master volume setting on the main
control panel, and the volume setting for that specific module defined in
the Settings window. This allows you to set specific settings for
individual modules, while still being able to control the overall speed,
volume, and balance independently from the main control panel.
Note that the Speed gadget in this window works somewhat differently from
the one in the main window. The main window's Speed gadget is meant to be
basically just for fast-forwarding through a song, while the Speed gadget
in this window allows you to tell MultiPlayer how fast to play this module
normally. This window also contains two extra buttons, 'PAL' and 'NTSC',
which set the Speed gadget to one of two common playing speeds.
End box and gadgets
These settings allow you to tell MultiPlayer when to stop a module that
normally doesn't stop by itself, or to make MultiPlayer stop playing the
module before it would normally end. The text box displays the amount of
time MultiPlayer will let the module play before stopping it, if you've set
an endpoint.
To set a module's endpoint, you must be currently playing the module
you want to change the setting for. (The Set button will only be activated
if this is the case.) When the music gets to the point where you would
like it to stop every time you play it, click the Set button. MultiPlayer
will record the endpoint and, since setting the endpoint implies that you
have reached it, the module will immediately end. Next time you play that
module, it will stop automatically at that point. To clear a module's
endpoint, just click the Clear button.
Filter gadget
This gadget determines how the low-pass filter (and the power LED) is
handled. Normally it's just set to 'controlled by module', so music
modules can turn it on or off as part of their effects. However, if a
particular module does things you don't like with the filter, you can force
the filter permanently on or off with this gadget, so the module can no
longer control it. Of course, this feature works only on module types that
allow MultiPlayer to control the filter.
Protracker tempo commands
This checkbox is only activated for standard ST/NT/PT modules. If it
is not set, the Protracker player interprets all speed commands in the
module as NoiseTracker and other older trackers did, and keeps the baseline
frequency at 50Hz (or whatever you set the speed to). If this checkbox is
set (the default), the newer Protracker tempo commands are enabled.
Basically, this option is here because there is no reliable way to
detect whether a module is using only NoiseTracker speed commands or needs
Protracker tempo commands. While most modules will work fine on either
setting, some will only play at the correct speed at one setting. If you
play a module and it suddenly starts going way too slow, or way too fast,
or otherwise plays at an obviously "wrong" speed, try flipping this
checkbox and start the module again. In general, older modules need this
checkbox to be off, while newer Protracker modules need it on.
Fade checkbox
If you select this checkbox, and the module supports volume control,
then when the module ends, instead of stopping immediately it will continue
for a couple seconds longer (most likely repeating an earlier part of the
song), gradually fading out. This is nice for the many modules that just
repeat over and over, and never really end. With this feature you can make
the "artificial" ending seem a little more natural.
Current button
Pressing this button will set the currently selected module to the same
as the currently playing module. Thus, if you are listening to a module
and decide you want to change something about it, you don't have to hunt it
down in the program list - just press this button, and you can immediately
make settings changes to the module you're listening to.
Close button
This button simply closes the Settings window. Like the Close button
in the Preferences window, it doesn't actually cause anything else to
happen, because whenever you change anything in the Settings window, the
changes take effect immediately.
Information Window
~~~~~~~~~~~~~~~~~~
The Module Information window contains a single read-only ListView
display which contains various miscellaneous information that MultiPlayer
gleans out of the currently playing module. For module types such as MED
and GMOD which have specific support for some kind of general text string,
that gets displayed here. For ST/NT/PT modules, this contains the names of
all the instruments (which composers often replace with messages, credits,
and greetings). The information window can be toggled on or off with
either the Info button on the Program window, or with the F5 key.
If the last instrument used in an ST/NT/PT module contains ASCII text
instead of normal instrument data, it will be displayed here also. It can
be as long as desired, may contain newline characters, and MultiPlayer will
automatically word-wrap long lines. (Just for you Maruku...)
Flashy Windows
~~~~~~~~~~~~~~
For your viewing pleasure, MultiPlayer contains some little gizmos that
you've probably seen before in Eurodemos and other players.
The Spectrogram window displays a bar graph of the frequencies
currently playing.
The Note Scroller window shows a miniature tracker-like display of the
notes scrolling up the screen. (You can't read the notes, but if you're
using MultiPlayer you're probably wanting to listen to music, not read it,
right?) This works only on Protracker-type modules.
The StereoScope window shows an oscilliscope-like view of the sound
coming out of each channel. The QuadraScope is basically the same thing as
the StereoScope, except it has a separate display for each of the four
channels. (You can have both the StereoScope and the QuardraScope active at
the same time if you want.)
All four windows can be toggled on and off from the Preferences window.
Each also has a function key that works from any of the windows. You can
toggle the Spectrogram window with F6, the Note Scroller with F7, the
StereoScope with F8, and the QuadraScope with F9.
All "flashy" window updating is done in a separate task with a priority
of -5, so turning on these windows should not degrade system performance at
all. However, this means that the windows will stop updating temporarily
when the system is heavily loaded.
Keyboard Shortcuts
~~~~~~~~~~~~~~~~~~
Several keyboard shortcuts are available from any MultiPlayer window
(except the file requester). Most of these have been mentioned before in
this document, but they are listed all together here as well. These keys
are listed below:
ESC key
Terminates MultiPlayer immediately (a shortcut for the close gadget on
the main window.
F1
Opens and closes (or, rather, zooms and unzooms) the main control
panel. Same as the middle mouse button or the zoom gadget on 2.0.
F2 key
Toggles the Program window (opens it, or closes it if it was already open).
F3 key
Toggles the Preferences window.
F4 key
Toggles the Settings window.
F5 key
Toggles the Module Information window.
F6 key
Toggles the Spectrogram window. (Also toggles the Spectogram item in
the Preferences window.)
F7 key
Toggles the Note Scroller window.
F8 key
Toggles the StereoScope window.
F9 key
Toggles the Note Scroller window.
Spacebar
If a module is currently playing, stops (or pauses) it without
unloading it, just like the 'Stop' button in the main window. If a module
is loaded but NOT playing, it continues or restarts it, just like the
'Play' button.
Delete key
Unloads ('ejects') the currently loaded module.
Up/down arrows
These switch to the previous or next modules in the program list,
respectively. In random play, these simply select another module at
random. (These are shortcuts for the 'Next' and 'Prev' buttons in the main
window.)
Left/right arrows
For modules that contain more than one song, these select the previous
or next song, respectively (shortcuts for the 'Song' cycle gadget).
Startup Options
~~~~~~~~~~~~~~~
When starting MultiPlayer from Workbench, you can extended-select the
icons of as many modules as you want when you start MultiPlayer. It will
add all of these modules to the program and immediately start playing the
first one (or a random selection, if you have selected random play in your
saved preferences). Additionally, you may set certain default parameters
in the ToolTypes field of MultiPlayer's Workbench icon; these are described
later in this section.
MultiPlayer supports a full set of 2.0-style command-line options. You
can get a brief list of them by typing 'Player ?' on the command line. To
get a brief description of the parameters, enter another question mark
('?') and press return at the prompt.
Following is a description of these command-line arguments:
DIR (synonym: DIRECTORY)
The first argument on the command line (or the argument preceded by
the DIR keyword, if you use the keyword) tells MultiPlayer what directory
to go to the first time it displays the file requester. This is also where
it will look for modules you specify on the command line (see below) if you
don't specify full pathnames for them. Using this option to specify the
directory where everything else comes from can save you some typing if you
specify several modules that reside in the same directory on the command
line.
PLAY/M (synonym: MODULES/M)
The second argument (if you don't explicitly use the DIRECTORY or
PLAY/MODULES keywords) begins a list of modules to put into MultiPlayer's
program list on startup and start playing immediately. MultiPlayer imposes
no limitations on the number of modules you can specify using this keyword,
although AmigaDOS command lines are currently limited to 256 characters.
After MultiPlayer starts up, instead of showing the file requester
immediately, it will load and begin playing the first module in the program
list (or a randomly selected module, if you have selected random playing in
your saved Preferences). Program list files act the same way as modules,
so you can specify a program file to load and start initially instead of a
list of modules.
PROG/K (synonym: PROGRAM/K)
You can use this keyword followed by the name of a program file as an
alternative to the PLAY option. If you use this option, MultiPlayer will
load the named program file on startup and just go idle, rather than
starting the first module immediately as it would if you used the PLAY
keyword. To start the program, just hit the "Next" or "Prev" gadgets in
the main window (or just hit the up or down arrow keys in any of the
MultiPlayer windows).
Note that, apparently due to a bug in 2.04, if you specify the PROG
keyword without giving a directory name as the first option, the PROG
keyword and the program get put together and interpreted as a module name
for the MODULE keyword! Therefore, instead of "Player prog mus:blah", just
use "Player mus: prog blah".
SCREEN/K
You can use this parameter to tell MultiPlayer to open its windows on a
screen other than the Workbench (or default) screen. Just supply the name
of the public screen as this parameter, and MultiPlayer will try to use it
for all its windows. The named public screen must already be open.
NOREQUEST/S
If you specify the switch, MultiPlayer will not display the file
requester immediately after it loads, even if you don't specify any modules
to start playing. If you don't specify any modules, MultiPlayer will
simply sit idle until you tell it to do something.
NOWINDOW/S
This switch causes MultiPlayer to load and run without opening its main
window. If you specify modules to start playing, MultiPlayer will play
them as usual, but you won't see any visual indication that MultiPlayer is
running. If you have activated a hot key in MultiPlayer's saved
preferences, you can later open the control panel with it. You can also
open the window through MultiPlayer's ARexx port, assuming you haven't
turned that off as well.
NOREXX/S
If you specify this switch, MultiPlayer will not open its ARexx port.
I don't know what you'd really need this option for, but it's there...
NODETACH/S
If you specify this switch, MultiPlayer will not automatically detach
itself from the CLI process. In this case, unless you RUN it, it will keep
your CLI window until you quit MultiPlayer.
If you run MultiPlayer from the Workbench, it will search through the
ToolTypes array in its own icon for parameters which are roughly equivalent
to the CLI parameters described above.
DIR (synonym: DIRECTORY)
PROG (synonym: PROGRAM)
SCREEN
These ToolTypes act exactly like the corresponding CLI arguments.
Simply enter one of these ToolType labels, then an equals ('=') sign, then
the appropriate text. For example, to load the program "Mus:DefaultProg"
on startup, add the ToolType "PROG=Mus:DefaultProg".
REQUEST
WINDOW
REXX
These ToolTypes perform the same functions as the similarly named CLI
arguments, but instead of simply being flags,they are YES/NO ToolTypes. For
example, to prevent MultiPlayer from opening the main window on startup,
enter "WINDOW=NO" into the ToolTypes.
ARexx Port
~~~~~~~~~~
Whenever MultiPlayer is running, there is an ARexx port available
called "RXTRACKER" which you can send various commands to. MultiPlayer's
ARexx port is designed to be (mostly) compatible with the program RxTracker
by Dominic Giampaolo. In addition, it has several extended features, and
of course you can use it to play all the different kinds of modules
MultiPlayer understands.
If MultiPlayer runs into an error when trying to load or play a module,
it generally returns an error code of 10 to the ARexx program. When any
error occurs, a descriptive error string is saved and you can get it with
the LASTERROR command.
A listing of the ARexx commands MultiPlayer understands follows:
LOAD <filename>
Loads a module into memory from disk. It is generally a good idea to
supply a complete pathname, since MultiPlayer looks for the module starting
at whatever directory the file requester last happened to be looking at.
This command does not start the module playing. If you want to start
playing immediately, you don't have to use this command at all - you can
simply supply a filename on the PLAY command and it will load and start
playing immediately. Note that unless you tell MultiPlayer to load a
program file, this command won't affect the program list at all - the ARexx
port in general operates independently of the standard user interface. If
you explicitly tell MultiPlayer to load a program file using this command,
then the new program list will replace the old one.
PLAY [<filename>] [<songnumber>]
Starts playing a module. If you supply the filename, MultiPlayer stops
any module currently playing and tries to load the specified module from
disk, like the LOAD command. If you don't supply the filename, MultiPlayer
plays (or re-plays from the start) an already-loaded module. (If no module
is loaded and you don't specify a filename, MultiPlayer returns error code
5 and otherwise does nothing.) For modules with more than one song, you
can supply the song number to play. Songs are numbered starting at zero.
If you don't supply a song number, the first one (song zero) is assumed.
STOP
Stops playing any module that is currently playing without unloading
the module. You can then restart it later with PLAY or CONTINUE.
UNLOAD
Stops and unloads any currently loaded module.
CONTINUE
Tries to restart a stopped module at the position it was at before the
STOP command was given. If the module has never been started, it simply
starts from the beginning. If the module was already playing, it does
nothing. If the module type doesn't support restarting, MultiPlayer
returns error code 5 and does NOT start the module - you can then use PLAY
to start again from the beginning if you want, or else chew out the user
for playing weird module formats.
OPENWINDOWS
Opens the main MultiPlayer window. It will be opened in the small
title-bar zoom state, and none of MultiPlayer's other windows will be
opened with it. If the window was already open, this command does nothing.
It returns an error if the window can't be opened. Remember that while the
window is open the user can use it to change modules and such, possibly
messing up your perfectly organized and timed ARexx-controlled playing
sequences.
CLOSEWINDOWS
Closes all MultiPlayer windows, if any were open. MultiPlayer remains
active, and continues playing any modules it was already playing.
LASTERROR
Returns an error message describing the last error that occurred that
had to do with the ARexx port. (Errors that the user causes by
manipulating the window do not affect this.) You'll have to have 'options
results' turned on for this to work, and the error will appear in the
'RESULT' variable.
QUIT
Causes MultiPlayer to terminate immediately.
Messages
~~~~~~~~
This section lists most of the error or warning messages MultiPlayer
can produce. Look here if you have trouble deciphering the meaning of one.
"Not enough chip memory"
Tracker-style modules generally must be loaded into one big continuous
chunk of chip memory. Therefore, even if the Workbench (or some other
program) says you have enough memory, it may not have one big enough chunk.
Close some windows, exit some programs. If all else fails, reboot and try
fresh.
"Not enough memory"
You really are getting low. MultiPlayer doesn't normally need too much
non-chip memory, since modules are always loaded into chip memory. If you
get this message, it means you don't have much memory of ANY kind
available. Better free up something quick.
"Required memory occupied"
You will only get this message from non-relocatable AMOD or GMOD
modules. It means that the module has a specific address it must be loaded
into, but part or all of the required block of memory is already in use.
Free up as much memory as possible and try again. If most of your memory
is free and you still can't load it, chances are there's some little
allocated fragment that some program has forgotten about that's still
sitting in the required area. Your best bet is to reboot and try on a
fresh system. If you have more than 512K of chip memory, try running my
program 'ChipMunch' (included with the official distribution of
MultiPlayer) just after you reboot to keep programs out of the commonly
used areas.
"Unknown module type"
MultiPlayer doesn't recognize the file you selected as one of the
module types it knows. Either this isn't a music module, or it's one that
it doesn't know how to handle. If it is a music module that MultiPlayer
doesn't know about, send me the module and player/interface code, and it
should make it into the next version of MultiPlayer.
"Corrupt module"
MultiPlayer recognized the module, but it didn't look right for some
reason. Maybe it's a module written with an incompatible version of the
music program, or maybe the module itself got munched somehow.
"Error playing module"
A general catch-all. This error usually is displayed as a result of
error reports from initialization routines of individual players. It
generally means that the module loaded fine, but the player had trouble
playing it. Sometimes it means the same thing as "Corrupt module", or it
might mean that the player ran out of memory but was too stupid to tell
MultiPlayer about it specifically.
"Can't load module"
The requested file was not found, or there was a disk error while
reading it. If you get this message after selecting a file from the file
requester, chances are the disk is corrupt (in this case AmigaDOS should
have already given you a requester saying so), or the file may be open for
writing from some other program.
"Directory not found"
Somehow you managed to tell MultiPlayer to load something from a
directory that doesn't exist. Maybe you moved the directory somewhere
else, or forgot an Assign somewhere. This usually only happens with ARexx
commands or loaded programs.
"Audio hardware in use"
MultiPlayer can't allocate the audio hardware through the audio.device.
This probably means that some other music editor or player is currently
running. Find the culprit program and close it. If all else fails, reboot
and try again.
"No CIAB timers available"
MultiPlayer generally uses one of the two timers on CIA (Complex
Interface Adapter) B for timing its music. However, other programs like to
use these also. In particular, (I believe) one of the timers may be in use
if the serial port is in operation. Other than that, music programs are
generally the biggest consumers of CIAB timers. Make sure no other music
player or composer programs are running, and try closing terminal programs
or other programs that use the serial port.
"Please decompress this module"
It is unlikely that you will ever get this message, but if you do, it
means that (a) the module MultiPlayer is trying to load is compressed
somehow (MultiPlayer had to use the xpkmaster.library to decompress it),
and (b) it is an AMOD or GMOD module that must load at an absolute address,
and (c) MultiPlayer would have to re-load the module rather than just
copying it to its final position because the memory the module occupied
initally overlapped the required module address. If you don't quite
follow, don't sweat - just decompress the module.
"Can't exit at this point"
You tried to exit MultiPlayer while an ASL file or font requester was
open. The asl.library file requesters currently don't provide any friendly
way for the client (MultiPlayer in this case) to close the file requester
before the user clicks on one of the gadgets or the close box. Thus,
MultiPlayer must refuse to exit until you close those file requesters
manually.
Supported Formats
~~~~~~~~~~~~~~~~~
MultiPlayer currently supports the following module types:
15-instrument SoundTracker modules (most anyway)
31-instrument SoundTracker/NoiseTracker 1.3D modules
Protracker 1.0-1.1B modules
SoundTracker 2.6 modules
NoiseTracker 1.3D packed modules (with or without the embedded player)
NoisePacker 2.01 modules
Digital Sound Studio modules
StarTrekker 1.2 AM/FM modules (Extra '.NT' file required)
MED 3.00-3.21 and OctaMED/OctaMED Pro modules
Note: Modules (MMD0, MMD1) only - not "Song&Samples" files.
Oktalyzer 4- and 8-channel modules
Uses my own 8-channel play engine. 8-channel modules will
be slightly higher quality on a 68020+ processor.
SoundFX V1.3 executable modules (Player V2.2)
Will probably ONLY work with this version, since it does
some run-time patching to make it play under MultiPlayer.
Future Composer 1.3 ('SMOD') and 1.4 ('FC14') modules
JamCrackerPro 1.0a modules
SoundMonitor 2.0 modules
SidMon 2.1 modules
Delta Music modules (two versions)
Mark II modules
Dave Whittaker modules
Face The Music modules (DO NOT COMPRESS!)
This is very kludgy at best - you must have "PlayFTM:" ASSIGNed
to the PlayFTM program file. (Didn't know you could ASSIGN
to a file? Now you do!) The procedure involves loading the
module, the external player, and then the module again. Ack!
Generic embedded-player modules that start with something like
jmp init(pc)
jmp music(pc)
jmp end(pc)
(Such as NoiseTracker 1.3 packed w/player modules)
AudioMaster III sequenced 8SVX sounds (mono only)
'XMOD', 'AMOD', and 'GMOD' formats described in 'Formats.doc'
Although sequenced 8SVX sounds are technically only sampled sound
files, they have some music capability and look promising. Besides, the
player also plays non-sequenced 8SVX sounds, so you can also play your
movie clips and such with MultiPlayer. (I'm not sure if AudioMaster III is
the only program that currently supports sequenced 8SVX files, but it's the
only one I've seen so far.) Stereo is currently not supported - sorry, I'll
get to that eventually.

a program was loaded as a module. (thx Jon Grout)
Added Yet Another Compatibility Hack (YACH) to the Protracker player (ptsplay)
to deal with old modules that stored repeat start in bytes instead of words.
Added "Nasty Audio" feature in Prefs window, which makes MultiPlayer allocate
auido channels at maximum priority: won't allow "beeps" and such above
the music, and avoids conflicts with certain ill-behaved terminal programs.
1.31 (R4, 23-Jul-92)
Major source code cleanup; code no longer uses regargs.
Eliminated overlay support (in preparation for a future metamorphosis...).
Added NoisePacker 2.01 support.

feature. (thx Jeff Saffold)
Fixed minor Guido bug that appeared in the program window.
Added OctaMED Pro 4- and 8-channel module support. (thx Teijo Kinnunen)
Added Cont gadget in control panel; Play gadget now restarts song. (sug Klinosky)

(Side effect: it is now possible to show both file requesters at once!)
File and font requester positions and sizes are now saved in
MultiPlayer's preferences.
Rearranged the function keys yet again. (THIS time it _should_ be for good...)
Added Module Information window.
(Displays instruments, scolltexts, even MaruSampleTexts...)
Redrew MultiPlayer's icon. (About time...)
Added AppIcon support. (You can drop modules into it even when MultiPlayer's
windows are closed or on another screen.)
Changed speed control range on the main panel to be more useful.
(The normal position is to the far left, and it can go VERY fast.)
Added sequence jump controls to the main panel.

Fixed a serious bug in Guido (the user interface system) that sometimes
caused crashes under 2.0.
Fixed a tempo bug in the Protracker player.
Modules in the program list are now played by double-clicking them.
(lets you delete and do other things on them without playing them.)
Added Settings window. (Get to it from the Program window.)
Rearranged the function key assignments yet again.
(Sorry - they should stay the same for a while now.)
MultiPlayer can now read parameters from its ToolTypes for options when
started from Workbench.
Added volume control to Oktalyzer 8-channel player.
Added Commodities support under 2.0 - only one copy of MultiPlayer
gets run at once, and you can pop it up with a hot key.
Two of the ARexx port's command names have changed: OPENWINDOW and CLOSEWINDOW
are now OPENWINDOWS and CLOSEWINDOWS.
Added "Save program with preferences" option (in the Preferences window).
Changed the random number generator, hopefully for the better.
Note: The 1.3 support in this version of MultiPlayer is very minimal. The
next version will probably not support 1.3 at all. Going, going...

Added PROG keyword to command line options.
(Lets you load a program file without starting immediately.)
Fixed Mark II player.
Protracker player now supports CIA tempo commands.
Created Quadrascope and Note Scroller windows.

(Never did find a real Oktalyzer 8-channel play routine.)
1.12 (29-Dec-91)
Protracker support added by replacing the NoiseTracker player with the
(similarly modified) Protracker 1.1B player. I haven't detected
any backward incompatibilities with NoiseTracker modules, but
tell me if you find any.
Oktalyzer 4-channel player finally tested and fixed.
(Yep, it didn't work at all. Sorry...)

(I'm not listing all the additions - there are way too many.)
Major changes and additions to Formats.doc.
Music no longer cuts off when file requester is displayed.
Removed built-in code compression. (Maybe I'll put it back in later.)
Audio device now allocated while playing music.
Fixed SoundFX player bug which caused crashing on advanced processors.
Players now use longer DMA delays (normally 300) only on fast processors.
(Wouldn't want to bog down you poor ol' 68000 users would we?)
Major rewrite of player selection code.
CIAB interrupts now defer to software interrupts to avoid hogging
CPU time in a high-priority interrupt.
0.95a (6-Sep-91)
Fixed bug where song position appeared when no module was playing.
Fixed ST/NT player bug for modules with negative song repeat positions.
