-
- 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. :-)
