My problem is not with discontinuities across notes but with the sound driver
stoping and restarting between assynchronous I/O calls. My envelop makes sure
that both beginning and ending are at $80 (00 on a unipolar DAC like on the
MAC) Is there a way to switch buffers on the fly using the ROM sound driver
in free-form mode
Has Anyone tried to drive the sound buffer directly? My main question is
how to write the interupt service routine so that the soound buffer
is neither over-run or under-run.
