I am trying to play a list of four-voice chords with SUMacC.  It seems
that SUMacC supports a different StartSound than is described in the
Sound Driver Programmer's Guide, version of 11/15/84; the SUMacC routine
supports only the four-voice synthesizer and does not provide completion
routines.

So, I am able to start a chord and make it last for any duration, but how
am I to know when it stops, so that I can start the next (SUMacC does not
provide a SoundDone function)?  Or, as the manual suggests, if I set the
duration to some large value to avoid clicks, how do I know when to change
the rate fields?

If anyone has successfully used SUMacC to play lists of chords, I'd like
to know how you did it.

Thanks,
Peter
