I'm toying with the idea of having SNDH playback in SNDH-Ed, wouldn't be hard to implement.
Evil, what I was saying to Stefan was basically the OS sometimes interferes with heavy CPU tunes, the tune were never meant to be played in multi-tasking environments. So I might add playback in SNDH with all timers off and played via VBL on ST's and Timer C on Falcon's etc.. we'll see
