Going from Monkey Island 2 (MI2), music blocks are stored in LFLF blocks, outside of the ROOMs, so they can be accessed globally. The containing sound block looks like this: | |||
Block name 4 bytes ("SOUN") | Block name 4 bytes ("SOUN") | ||
| Line 26: | Line 26: | ||
Every track is stored in MIDI format, in order to make use of the iMUSE technology through System Exclusive (SysEx) messages. | Every track is stored in MIDI format, in order to make use of the iMUSE technology through System Exclusive (SysEx) messages. | ||
Due to the predominance of the Sound Blaster and Adlib/OPL FM technology at the time | Due to the predominance of the Sound Blaster and Adlib/OPL FM technology at the time, in at least MI2 every musical SOUN block contains an ADL block. | ||
==Mac0== | |||
From Markus Magnuson (superqult) we got this information: | |||
4 bytes - 'SOUN' | |||
BE 4 bytes - block length | |||
4 bytes - 'Mac0' | |||
BE 4 bytes - (blockLength - 27) | |||
28 bytes - ??? | |||
do this three times (once for each channel): | |||
4 bytes - 'Chan' | |||
BE 4 bytes - channel length | |||
4 bytes - instrument name (e.g. 'MARI') | |||
do this for ((chanLength-24)/4) times: | |||
2 bytes - note duration | |||
1 byte - note value | |||
1 byte - note velocity | |||
4 bytes - ??? | |||
4 bytes - 'Loop'/'Done' | |||
4 bytes - ??? | |||
1 byte - 0x09 | |||
