Yes. SoundMaster supposedly still uses the FFSynthRec form of sounds,
described in IM-II while SuperClock (and then supposedly TimeKeeper)
use snd resources and SndPlay. If you try to play a snd resource while
the FFSynthRec is playing, you'll be in deep trouble (or the other way
around...)

Someone said this would be sixed in System 7, at least they hinted that
you would be able to have more than one SndChannel at one time. This would
sure make things easy for game writers ! Don't know if it's true, though.

The present problem is that you can't allocate two independent sound channels
at one time, you'll have to mix the sounds together "on the fly" and then
play the resulting sound. Annoying, and not very convenient for real-time
applications.

About my INIT, if anyone wants just the INIT part, feel free to ask me for
it. You'll have to configure it using ResEdit, though, since the cdev
still doesn't work and I haven't the time to fix it right now. I KNOW that
this INIT really plays a startup snd resource even on an SE/30 - and I
think it should work with any Mac running system 4.2 or later (oh, say 6.0
to be on the safe side... :-)

Already in System 4.2 Apple encouraged developers to use the snd resource
format. It's a shame that some programs don't take advantage of this...
