From the IBM "FastTracker" v 1.00 Music editor:

|
|
-----------------------------------------------
|
||
|
|
|
||
|
|
'The Triton FastTracker' v1.00, last change: 12/13/92
|
||
|
|
Coded by Mr. H of TRITON in the autumn of 1992.
|
||
|
|
IBM Freeware.

About the Formats:
|
||
|
|
------------------
|
||
|
|
The samples are stored in 8-bit signed raw format.
|
||
|
|
|
||
|
|
There is no header, I use the time and date field to store repeat and
|
||
|
|
replen information. The repeat is stored in the lower word and replen
|
||
|
|
in the higher. The maximum sample size is 64K.
|
||
|
|
|
||
|
|
The 4-channel modules are stored in the common 31-instrument module format.
|
||
|
|
6 and 8 channel modules have a simmilar format, but there are diferences:
|
||
|
|
|
||
|
|
# The 4-byte field at offset 1080 contains 6CHN or 8CHN instead of 'M.K.'.
|
||
|
|
|
||
|
|
# Each row in the pattern is wider.
|
||
|
|
|
||
|
|
|
||
|
|
About the Format Effects:
|
||
|
|
-------------------------
|
||
|
|
All of the effects in ProTracker 2.2A is implemented except Filter Toggle
|
||
|
|
and Invert loop:
|
||
|
|
|
||
|
|
00 - Arpeggio
|
||
|
|
01 - Portamento Up
|
||
|
|
02 - Portamento Down
|
||
|
|
03-0F - (Same as PT 2.2A)
|
||
|
|
E0 - Not Implemented
|
||
|
|
E1-EE - (Same as PT 2.2A)
|
||
|
|
EF - Not Implemented
|
||
|
|
|
||
|
|

|
|
But wait! There's more...
|
||
|
|
|
||
|
|
FastTracker "clone" formats:
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
There are a number of MOD formats basicly exactly the same as the 8-track
|
||
|
|
IBM FastTracker format, but with a different signature at 1080 different
|
||
|
|
than "8CHN". Here are some:
|
||
|
|
|
||
|
|
Signature Program System
|
||
|
|
|
||
|
|
M.K. Grave Mod IBM (*.WOW modules)
|
||
|
|
CD81 Octalyser Atari STe/Falcon (not the same as Amiga "Oktalyzer")
|
||
|
|
OCTA ?? ?? (exists, according to kurtt@sfu.ca)
|
||
|
|
|
||
|
|
|
||
|
|
Unlike native FastTracker format, some of these formats _do_
|
||
|
|
use the Filter Toggle and Invert Loop commands! (Like Octalyser)
|
||
|
|
Never assume they are always unused by every program that
|
||
|
|
creates this family of files.
|
||
|
|
|
||
|
|
If you want to use these files in a program that plays FastTracker
|
||
|
|
modules, just use a file hex-editor and change the signature to "8CHN".
|
||
|
|
This does not seem to work with Amiga StarTrekker "FLT8" or "EX08"
|
||
|
|
signature files, however.
|
||
|
|
|
||
|
|
It might not be hard to write a routine that detects 8-track
|
||
|
|
modules, even without knowing what the signature is, based on other
|
||
|
|
information.
