Abyss' Highest Experience (AHX) is an Amiga tracker designed to make C64-esq chiptunes. It is built to look like protracker and has synthesized 4-channel chiptunes which simulates the sound of the Commodore 64. Please note that ahx does not emulate an actual SID chip, it just attempts to sound like it.



There is no support for sampled instruments as chip tunes are made to be as small in size as possible. So an average AHX tune has a length of about 200 bytes - 5 kbytes (unpacked).
All waveforms of the C64 are supported:
- Triangle wave,
- Sawtooth wave,
- Square wave, and
- White Noise.
Also Hi-/Lo-Pass filtering effects are supported.

This tracker works on Amiga only. If you want to run it on Windows, Linux or MacOS, you'll have to install an emulator first.

Expert tricks

From the FAQ:
Why does the note I enter appear on all 4 voices?
Because you enter the note into one track and when starting AHX, all 4 voices display track 0. In the position editor you enter what track to play on what voice, you can if you want play your bass-line e.g. on 2 voices (left+right channel) if you want, your decision.

Why are my AHX-tunes so big in size (compared with the included songs)?
Songsize depends mainly on the number of tracks you use (Number of positions is not very important). Try to cut down the track-length to 16 or 32. This will save a lot of space because you can arrange drum or bass tracks normally without a lot of change.

Sometimes some or all voices get muted in AHX Editor or the Delitracker-AHX-replay. Why does this happen?
AHX avoids to reset the sample offset in the audiohardware when playing a instrument. Resetting the sample-restart will produce a small 'click' that doesn�t hurt when you use 'normal' samples. When using small synthetic waveforms this small click is really annoying. So AHX sets the sample offsets only once at the beginning of the replay and then never again. When another application uses the audiohardware (e.g. DisplayBeep()) the sample offsets will be changed and strange results or muted voices will occur.

It seems no more development is taking place anymore.
