You don't understand. The sound driver on 68k takes so much time on Genesis because it has to handle the DAC itself. Even though the C2 board does not have a Z80, it DOES have a separate chip for DAC playback that does not cost anything on the 68k.
So the only issues are playing back the music track and triggering samples, which takes almost no time.
