Digibooster and some other tracker supports ahi. But the problem is the following:
My 68040@33MHz is too slow for my old 16bit 32channel xm musics on digibooster. Some of my 16ch which is not using in the same time all of 16ch playing perfectly. (about 12ch) Maybe i'm using the wrong version of ahi. (6 or something like that, don't blame i don't remember correctly)
Or the problem is with my gfx card, when i choose any gfx card screen mode the system request window draw things slow as hell. So maybe there is a bug or something.
And digibooster has some cool features in its own days, but now its feels like old, dusty, and noisy music maker software.
I tried some version of old ahi which is made for ppc cards. There is some speed gain, but i can't configure it correctly so, i dropped the idea. (And this version is sharware, not freeware)
Anyway making music with trackkers was good in the '90, but now VST plugins ruling the world. And for crystal clear drum-machines, and other synths withs stereo samples and full of effects demand a very high processor speed. Even on my Core2 Duo CPU gets sometime 70-90% load on fruityloops 7.
