Abyss Highest Experience - what the
demo scene group
Abyss were forced to rename their excellent
SID sound like tracker formerly known as
THX into, as some stupid American guys didn't like their
trademark being
violated.
The sound of an AHX module is probably the closest the
Amiga will ever get to the true
SID sound from the
C64.
Analog it is not, but it's fairly close, and due to the file format, interesting modules lasting five minutes can easily have an uncompressed size less than 5 KB.
Technical features of AHX is a sample editor, where you can only specify type of sound (tri, square, sine, or noise),
attack, sustain, and decay. For the people
familiar with the sound system of the C64, this might ring a bell. All tracks have the same length, but this length can vary from 1 to 128 (128 is
AFAIR). Patterns are simply tracks modulated. (Expressions used as in the
trackers of the mid
90s)
