- --------M-MTM-------------------------------
-
- The MTM format is generated by the Multi Track Module tracker by the
- demo group Renaissance. The tracker features up to 32 channel digital
- music. Instead of saving whole patterns, the tracker only saves the
- different tracks and the data which tracks should be played together at
- which time, thus saving some pattern space.
-
- OFFSET Count TYPE Description
- 0000h 3 char ID='MTM'
- 0003h 1 byte Version data
- upper nibble is major version number
- lower nibble is minor version number
- 0004h 20 char ASCIIZ song name
- 0018h 1 word Number of saved tracks.
- ="NOT"
- 001Ah 1 byte Highest pattern number saved
- ="NOP"
- 001Bh 1 byte Last order number to play(=Songlength-1)
- 001Ch 1 word Length of extra comment field in bytes
- ="XSZ"
- 001Eh 1 byte Number of samples
- ="NOS"
- 001Fh 1 byte Attribute byte (currently defined as 0)
- 0020h 1 byte Beats per track
- 0021h 1 byte Number of tracks
- 0022h 32 byte Pan positions of the voices
- (0=left, 15=right??)
- 0042h "NOS" rec Instrument data
- 22 char Sample name
- 1 dword Sample length in bytes
- 1 dword Start of sample loop in bytes
- 1 dword End of sample loop in bytes
- 1 byte Fine tune value for sample
- 1 byte Default volume for sample
- 1 byte Attribute byte, bit mapped
- 0 0=8 bit sample,1=16 bit sample
- 1-7 undefined (set to zero)
- 0042h+ 128 byte Pattern order data
- "NOS"*37
- 01C2h+
- "NOS"*37 "NOT" rec Track data
- Each track is saved independently and has
- the size of exactly 192 bytes. Each track
- is arranged as 64 3-byte notes with the
- following format :
- 64*3 byte BYTE 0 BYTE 1 BYTE 2
- ppppppii iiiieeee aaaaaaaa
- p = pitch value (0=no pitch stated)
- i = instrument number (0=no instrument number)
- e = effect number
- a = effect argument
- The effects are the standard Protracker
- effects.
- 01C2h+ ("NOP"+1)*32 word Track sequencing data
- "NOS"*37+ This is the list of which track is used
- "NOT"*192 as which voice in each pattern. One track
- can be part of many patterns, the drums
- for example.
- Track 0 is never saved but is always
- considered as an empty track. That means
- that counting really starts at one.
- The data is organized in sets of 32 voices.
- The first word contains the information which
- track is used in pattern 0, voice 0. The next
- word is for pattern 0, voice 1, etc., this
- is repeated for each pattern, 32 words for each
- saved pattern.
- 01C2h+ "XSZ" char Extra comment field. This contains some
- "NOS"*37+ message or something.
- "NOT"*192+
- ("NOP"+1)*32*2
- 01C2h+ ? byte Raw sample data(unsigned).
- "NOS"*37+
- "NOT"*192+
- ("NOP"+1)*32*2+
