Soundtracker 2.6 / Ice Tracker file format
Soundtracker 2.6 written by MnemoTroN/Spreadpoint, 05-Nov-1990
IceTracker by Icepic, v1.1 10-Jan-1993
Format description by Claudio Matsuoka <claudio@helllabs.org>, 24-Jan-2000
Both trackers available in Exotica (and probably Aminet).
Soundtracker 2.6 module format, also used by Ice Tracker, is closely related
to the standard (Protracker) module format and has each 64-row track stored
independently. The format is, of course, big-endian.
From the Ice Tracker documentation:
This [sub-patterns] idea was initialy implemented by
MnemoTroN/Spreadpoint in his SoundTracker v2.6 (...).
Basically now a pattern instead of being made up of 4
joined tracks (ie: Channels 1,2,3 and 4 were previously
classed as one pattern) are now individual sub-patterns
in themselves, that is that now it is possible to
independantly call up a single sub-pattern to repeat on
a certain track (ie: the main beat, for example) without
constantly copying it into every 4-track pattern as was
previously required. Play around with it and you'll get
the idea.
That's what you want? That's what you get. Follow me:
