Howdy,

I'm using the Sound Manager to play a rapid series of 'snd ' resources
to simulate the sound of a snare drum being played. I had a program to
play a series of sounds in the desired tempo and it worked, but then I
added it to a larger application and the timing is now off.
I'm using the method :
1) allocate a new sound channel (w/o a synthesizer)
2) play a format 2 'snd ' resource
3) dispose of the channel 
to play the sounds. The timing is done by checking the TickCount(). Each
drumbeat has a set amount of time to play before the next one is played.
Everything was working until we took my code and changed it to a procedure
within a larger application. Now the timing is off whenever the type of
sound to play changes. But we Got all the resources before that and are
only changing the handle in SndPlay.
We're using Think C and TransSkel. 
The only things we can think of are internal Mac stuff with memory allocation 
of the snd resources, or maybe TransSkel messed up something. The resources
are preloaded and non-purgeable though. 
It's frustrating because it worked as a smaller stand-alone program but not
as part of the larger application, where it has to. If anyone has any ideas
we'd welcome them. Thanks,
