Music - Formats compiled modules known musical editors. Pro Tracker v2.101 by GDC, A standard player.
(C) VfNG / NEW
Many in the process of writing the effects of missing
somewhere a couple of thousand cycles. Usually in such cases,
the first thing in trying to optimized music player. I think
that no harm will be published format compiling modules most
famous music editors. It's a little easier for you life and make
easier picking in the old PLAYER'e.
Let's start with the PRO TRACKER 2.101 by GDC. The next time
may be, we will publish the format of music STP PRO.
Terminologiya:
QUARK: those elements that comprise SAMPLES, ORNAMENTS.
QUANT: QUARKS number in each cell PATTERN. In fact, the
playback speed;
PATTERN: Verse;
POSITION LIST: order of play PATTERNS;
POSITION: position POSITION LIST;
Format compile the module:
+0
DELAY-number QUARKS, for which played a QUANT;
+1
MUS_LEN-number positions in the melody;
+2
LOOP TO POSITION-position number, which will be
loop by playing the whole tune (0 - # FF);
+3,64
SAMP_A-shift from 0 to each of the 32-SAMPLE. SAMPLE number
0 is not described. His number is used to mute the channel.
+67,32
ORN_A-similar SAMP_A for 16 ornaments. Ornament Room
0-absence of ornament.
+99,2
PAT_OFFSET-offset from 0 up to the first descriptor
PATTERN'ov PAT.
+101,30
NAME-the name of the music in ASCII.
+131
POSITION LIST-list position numbers PATTERN for each
position. End Table-# FF.
+?
PAT-descriptors PATTERN'ov. Kazhdy PATTERN consists of 3
channels. In this table, the bias from 0 to descriptors for
each channel PATTERN. Thus, by 6 bytes / PATTERN. End Table-#
0000.
+?
CHAN-channel descriptors. Channel is represented as a list
of bytes, which are analyzed as follows:
LOOP LD A, (DE)

L11 Disable command and go to LOOP.
L10 Extract the next byte, it value addition to the frequency
NOISE. Then, on the LOOP.
L9 Extract three bytes. In the 1-m value PORT, ie the number
that will be added to the current frequency of the notes. It
should be noted, that the frequency of the highest notes of the
smallest and most low-at most, it means: put. 128-255, denying.
0-127. In 2 nd and 3 rd byte difference in the frequency values
of the new (the one which caused PORT) and the previous one
note. There is a compiler error, which incorrectly identifies
this value if a new note stands at the beginning PATTERN.
Command to turn off when the amount the additions of a exceeds
the value of +2, +3. Go to LOOP.
L8 Extract 1 byte. It value GLISSADE. Signs of similar-
PORT. Then go to LOOP.
L7 Extract 1 byte. It value for DELAY (playback speed). Then go
to LOOP.
L6 In the A volume (0-F). This value is multiplied by 16 and
added to the top of the table TABL1. To the resulting value
should be treated like the top of a 16-byte table, which
contain values for the amplitude of the coprocessor registers
for each value extracted from the SAMPLE. Then go to LOOP.
L5 In the A-number QUANTS not need to analyze the channel, ie,
QUANTS distance between successive changes in the parameters of
the channel. Then, on the LOOP.
L4 In the A room ornament. If equals 0, then the absence of
ornament. Go to LOOP.
L3 If A = 0 then exit. If 0
