LU21.arc contains an updated version of LU2. No major changes
were made; but the pitch-setting of instruments has been
improved (fixed, I hope), and the timing is better.
I have received zero response from the earlier <shareware>
release of LU. I guess no-one is using it... oh well. =-(
Michael Sheldon 05-Aug-1988
----------------------------------------------------------
This program is referred to as 'LU2', rather than simply 'LU'
because an earlier version that didn't support IFF instruments is
floating around. <by all means, rename as you see fit! =-)>
============================================================
LU-- [IFF]SMUS Music Player by Michael Sheldon, copyright 1988
Usage:
LU [score_name] [instruments directory]
------------------------------------------------------------
Setting the instruments directory:
LU uses many features of the ARP library; in particular, the ability
to set and retrieve 'environment variables'.
The environment-variable "INSTRUMENTS" (case-sensitive--'instruments'
won't work) is the directory that will be searched for the instruments
the score requires.
Externally___
You may set INSTRUMENTS prior to calling LU, i.e.
set INSTRUMENTS=DF1:Instruments
or you may set it from within LU. Once INSTRUMENTS is set, either
by the external command 'set', or internally, it will remain so
until changed.
Internally___
If INSTRUMENTS isn't set when LU is invoked a file-requestor will
open, with 'INSTRUMENTS' in the directory string-gadget. You may
clear the directory name with 'Amiga-X' (hold down the right-Amiga
key while depressing the x key), or otherwise edit the name as you
see fit.
This requestor is only for setting the directory, not selecting
instruments. Clicking on an instrument name within the directory
will have no effect.
Once INSTRUMENTS is set, LU may be invoked with simply the score-name.
i.e. 'LU <score-name>'. You may specify <on the command-line>
an instrument directory other than what INSTRUMENTS is set to if you
choose...
If you don't have instruments immediately available, or you just
want to get an idea of what the score sounds like, set INSTRUMENTS
to any directory (or disk). LU will report that it can't find the
instruments that the score calls for, and proceed to play the song
with simple internal voices.
-------------------------------------------------------------
Invoking LU without a Score Name:
By typing 'LU' by itself you enter an interactive mode, whereby
you may play scores one after another without having to run LU
again.
The best part about this is that once an instrument has been loaded
for a score it is subsequently available for other scores you select.
Depending on memory, of course, there is an unlimited number of
instruments that may be resident (in RAM). If LU doesn't have to
load instruments to play a score the delays between scores is kept
very short.
Note: a score may be aborted at any time with <control-C>.
-------------------------------------------------------------
LU and ARP:
For those unfamiliar with ARP: briefly, it's the 'AmigaDOS Replacement
Project', the aim of which is to free the Amiga from the inadequacies
of the current AmigaDOS, bring new functionality to the system, increase
reliability, and make the programmer's task much easier (did I leave
anything out?).
You must have 'arp.library' in your LIBS: directory, or LU will not
run. More precisely, you'll need arp.library version 32 or later.
<Without ARP, LU would be twice (at least) as large, slower to invoke,
and not available yet.>
-------------------------------------------------------------
LU will handle DMCS scores, InstantMusic scores, DMCS-SMUS scores,
and to a limited degree Sonix scores.
Only instruments of the 8SVX type are handled, so those great Sonix
instruments are not available. You can make copies of your 8SVX
instruments, renaming them to what a score is seeking to get around
this.
In the future I may add support for Sonix instruments, and/or
the ability to set alias's for instruments.
-------------------------------------------------------------
There are nuances in a SMUS score that LU does not handle, and
simply skips over. While not ideal, the resulting sound is fairly
good; I hope you agree. =-)
=============================================================
I am releasing 'LU2' as shareware. This means that if you like it
and use it you are requested to send a contribution. The number of
people that do this will determine whether there will be any more
'non-commmercial' releases.
The suggested contribution is $15. Sending this amount will entitle
you to automatically receive a disk with the next upgrade as it becomes
ready.
