OctaMED Soundstudio should work on it.
Without an emulator.
DITTO! You'd think there would be a way to keep it from Locking up under MorphOS and assign the audio output to something MorphOS is friendly with.
If AMiga OS 4 can do it, then so should MorphOS.
AROS is x86, so having to use emulation is expected.
On that note, I'm looking forward to Digitbooster 3!
