PART DATA FORMAT
The following is the format of each part, starting with the address pointed to byte the absolute pointer to the
part (offset by 400H):
00H LSB of number of bytes in part, including header.
01H MSB of number of bytes in part, including header.
02H LSB of offset from start of part to address of start of track 8 data
03H MSB of offset from start of part to address of start of track 8 data
04H LSB of offset from start of part to address of start of track 7 data
05H MSB of offset from start of part to address of start of track 7 data
06H LSB of offset from start of part to address of start of track 6 data
07H MSB of offset from start of part to address of start of track 6 data
08H LSB of offset from start of part to address of start of track 5 data
09H MSB of offset from start of part to address of start of track 5 data
0AH LSB of offset from start of part to address of start of track 4 data
0BH MSB of offset from start of part to address of start of track 4 data
0CH LSB of offset from start of part to address of start of track 3 data
0DH MSB of offset from start of part to address of start of track 3 data
0EH LSB of offset from start of part to address of start of track 2 data
0FH MSB of offset from start of part to address of start of track 2 data
10H LSB of offset from start of part to address of start of track 1 data
11H MSB of offset from start of part to address of start of track 1 data
12H LSB of number of beats in part in BCD format (0 beats =
13H MSB of number of beats in part in BCD format empty part)
14H MIDI channel for track 8 (0=unchanged, or 1-16)
15H MIDI channel for track 7 (0=unchanged, or 1-16)
16H MIDI channel for track 6 (0=unchanged, or 1-16)
17H MIDI channel for track 5 (0=unchanged, or 1-16)
18H MIDI channel for track 4 (0=unchanged, or 1-16)
19H MIDI channel for track 3 (0=unchanged, or 1-16)
1AH MIDI channel for track 2 (0=unchanged, or 1-16)
1BH MIDI channel for track 1 (0=unchanged, or 1-16)
1CH-29H 14 digit ASCII name of part
2AH-? Data for track 8
?-? Data for track 7, etc...
Part data must follow these rules:
1) Track data must be in the order track 8 through track 1.
2) An empty track must exist as a track with no notes in it. The data for an empty track would be 7 bytes
long, as follows: 80H, xLSB, xMSB, 00H, 80H, 00H, 00H, with x = the number of clocks in the part,
i.e., number of beats * 96. The number of clocks must be divisible by 96.
3) Adding the number of bytes in a part to the absolute pointer of a part should point to 1 byte past the
last byte of the part.
