The sound isn't bad. It's an 8-bit wavetable chip with 64KB of sample RAM. There is a stupid bug (DACs get reset to zero when the sample loops) and for some reason Apple wired it up for mono only even though it's a stereo chip. But you can play MODs on it and stuff. IIRC there was (at least one) demo which had music ripped from an Amiga demo.
