File format
The file begins with a header:
| Data type | Name | Description |
|---|---|---|
| UINT32LE | lenFile | File length (sometimes files are longer than this though) |
| UINT16LE | numInstruments | Number of instruments in the file |
| char[4][numInstruments] | titles | List of four-character instrument titles, not null-padded, one for each instrument one after the other with no separators. |
| UINT32LE[numInstruments] | offInst | Offset where instrument data begins, relative to the end of this header |
This is followed by the instrument data. The offInst[0] is always zero, as the instrument offsets are relative to the end of the above header and the first instrument always follows directly.
Instrument data
Each instrument begins with the following data.
| Data type | Name | Description |
|---|---|---|
| UINT16LE | lenInst | Length of instrument data, in bytes (0x64 for Adlib, 0x5D for MT32, Tandy, and PC Speaker |
| UINT16LE | unknown | Always 0x0001 |
