============================================================================
First, there are two power LEDs that are not part of the main LED panel.
One is in the upper-left of the CD panel, and one is in the upper-right
of the EdSynth keyboard.
The main power LED (on the CD panel) lights up after EdPlayer has finished
loading (or trying to load) any startup-scripts (see the Intro file).
The EdSynth power LED is just on all the time EdSynth is visible.
---------------------------
Now for the main LED panel:
Ah, such a complicated, confusing display. Not really! It's pretty simple
when you break it down.
OK, I'm going to start in the BOTTOM-LEFT, and go RIGHT. You'd better be
looking at the display while you're reading this (I'm looking at it while I
write it)! First, in the bottom-left, you see the RANDOM ("?") LED. It's
probably dark, so look very closely. It only lights up if you have a
"program" active that is in RANDOM mode (see the "?" in the button section
above). Just to the right of it is the actual PRG led, which lights if you
have any program at all (see PRG in the button section). Next, to the
right of PRG, is a little bent arrow. This is the LOOP LED (see LOOP in
the button section). To the right of that is the FADE LED which, by
default, is lit up when EdPlayer starts (see FADE in the button section
above). Then there are the FILTER OVERRIDE and FILTER ON/OFF LEDs (again,
see FILTER above). Then there are two LEDs that say "PAL" and "NTSC".
When EdPlayer starts, PAL is lit up, because ProTracker mods should be
played in PAL. You can change this for tempo correction of old
NoiseTracker modules, but they BOTH go dark for MED modules which need no
such correction. To change it, see "T" (Tempo) in... you guessed it... the
button section, above.
----------------------------------------------------------------------------
AND NOW, THE LEDs which are *NOT* explained in the button section, above.
YEAH!!
To the right of PAL/NTSC you see something like a four-bar VU-meter. As
the Amiga has four built-in voices, it shouldn't be too hard to figure out
what this does. Fun to watch when playing a song! This can also act like
a spectrum analyzer, and the "VU" or "AN" LEDs tell you which mode it's in.
To the right of that, you see a few LEDs (we're now as far right as we can
go)! The "PT-MOD" will light up when EdPlayer has a
(Sound/Noise/Pro)Tracker module loaded, and "MED 3.21" will light up when
there is a MED module loaded. "PAUSE" will light up when in pause mode,
and will BLINK when EdPlayer is FADEing to a pause. The "MIDI" light is
special: The whole MIDI thing lights up when MIDI (direct or midi.library)
is active, BUT, when a song is playing, the five red dots (representing
MIDI prongs on the end of a MIDI cable) will go dark again, and BLINK as
MIDI messages are passed out of EdPlayer! I think this is a neat effect
during MIDI songs.
----------------------------------------------------------------------------
And finally, the digits. These digits are controlled by the "Display"
button (which looks like a calculator "8") and have FOUR MODES.
MODE 1: Below the digits you see TRACK, POS, and TOTAL. When a song is
loaded, it's current position will be displayed above "POS",
with the total number of positions being displayed above "TOTAL."
Above "TRACK" you may see a program number, if this song is
part of a program. SPECIAL CASE: If you are in a program, but no
song is currently loaded, the "POS" will disappear, allowing
"TRACK" and "TOTAL" to work together, displaying the current and
total number of songs in the program, respectively.
MODE 2: In this mode, you see LINE, POS, and PATT below the digits. The
"Pos" light is exactly the same as in mode 1, displaying the
song's position. The "LINE" shows a much more exact position
inside the POS itself, and "PATT" shows the current pattern
number being played. This mode is for people who like to
follow the progress of their songs through the player, and also
for people like myself who just want to see all the busy, changing
numbers going on.
MODE 3: This mode just displays your Amiga's system time. You can
distinguish this mode by the "AM" or "PM" that lights up. To set
the time, just use the AmigaDOS "Date" command, or some other
utility. Actually, if you have a battery-backed-up clock in your
Amiga, the time should already be set from your startup-sequence
via the "SetClock Load" command. Why am I explaining this?!
Go read your Amiga's manual if you're confused about system dates!
MODE 4: This mode just displays the system date, in MONTH, DAY, YEAR
format. You can distinguish this mode from the others because NO
funny LEDs like "Track" or "AM" or even ":" or "/" come on.
To set the date, see MODE 3 above.
Well that about wraps it up for the LED display. Oh yes, if EdPlayer tries
to display a number greater than 99, two dashes "--" should appear instead.
To read a number that is greater than 99, see the ARexx section for queries
APOS, ATOT, APRG, and APTO. Also, the two dashes appear above "TRACK" when
there is a program, but no selection in the program is "current". Pressing
PLAY at this point will move the current selection to 01 if necessary
before loading & playing.
Note that there is NO LIMIT on the number of songs in a program!! NOT 99,
NOT 65536, OR ANYTHING LIKE THAT! This is because I used Amiga exec's
wonderful doubly-linked lists to handle the list of names. SO, you can
keep adding names to a program until your whole Amiga's memory is full of
nothing but filenames, and you may not have enough memory left to actually
load a song, but you will NEVER get a "Too many names in Program" error.
Well, actually, if the memory allocation for the filename storage fails,
you can get an out-of-memory error from EdPlayer, but if you're THAT close
to being out of memory, you're probably headed for a GURU real soon!
Anyway, just thinking about typing all those millions of filenames makes my
fingers hurt!
EdP v2.0 note: Ummm, well, after that big speech about "no limits" and
such, I hate to say this, but there is a bug in the
random mode that lets it only select songs from the
first 65535 or so. So, if your optical storage
device has 70000 songs on it, and you try to use
random mode, it will never actually select the highest
few thousands of songs. I hope this doesn't inconvenience
anyone; I will try to fix it next version. :-)
