The lip-sync tags provide timing information, and are 16-bit LE values, representing positions in the speech file. Sound data variable ('Crea' block / VOC file) 01 23 30 is equivalent to 1 35 48 in decimal.įrom Indy 4 onwards, sound effects and speech are stored in a separate resource file called 'MONSTER.SOU'. The scene at the lookout following the intro uses the same music as the opening, but starts at position 1 min 36 sec. The six remaining values 26-31 (0x1a-0x1f) are all 00 if you want the music to start at the beginning of the track.Īn example of music not starting at the beginning: Values from offsets 0-23 (0x00-0x17) are all the same, so just copy data from an existing SOUN.Īt offset 24 (0x18) track number in hex format (for new music not in original start with track decimal 24 or hex 18).Īt offset 25 (0x19) seems to be loop, opening uses 01, scummbar uses ff. For MI1/CD at least, the 'SOUN' block size is always 32 bytes and presumably points to the CD track to play. Games that use CD tracks (Loom/CD, MI1/CD, Zak256/FM-TOWNS) are a bit different. The implied data offset is 0x1A, and the VOC version is 0x010A. The actual sound data is stored in the Creative VOC format, without the header information. 001 resource files, and are sub-blocks of 'SOUN' blocks (see the music section above).ĪUhd and AUdt are used in Monkey Island, while WVhd and WVdt are used in the non-interactive demo of Sam & Max. 'ORGA' - Drawbar Organ (16 but could also be 17-20)ĭigitized sounds first appeared in Monkey Island 1 & 2.

'HORN' - French Horn? (60) or English Horn? (69) 'PIPE' - Church Organ? (19) or Flute? (73) or Bag Pipe (109)

Instruments (and General Midi equivalent):

You can find the original patent document here, and some technical details can be found here.įrom Markus Magnuson (superqult) we got this information:ĭo this three times (once for each channel): iMUSE allows operations like conditional jumping & looping, adjusting the volume of parts, turning parts on and off, changing instruments, and detuning parts. This basically consists of standard MIDI data, with embedded System Exclusive (SysEx) messages that act as markers in the song. Aside from SBL, each of these blocks follow the same basic pattern.īlock name 4 bytes ('ROL ', or 'ADL ', or 'SPK ')Įvery track is stored in MIDI format, in order to make use of the iMUSE technology through System Exclusive (SysEx) messages.ĭue 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.įrom SCUMM v5 onwards, LucasArts games used a dynamic music playback system called iMUSE. They can also store a single SBL block for digitized sound (described in a later section). The music block may contain any combination of ROL (Roland MT-32), ADL (AdLib/OPL FM), or SPK (PC speaker) blocks.

The redundant header is possibly due to building on a legacy implementation, or for easier identification in the table stored in the. The containing sound block looks like this: Going from Monkey Island 2 (MI2), music blocks are stored in LFLF blocks, outside of the ROOMs, so they can be accessed globally.
