[comp.sys.mac.programmer] How to continuous sound?

2fmlcalls@kuhub.cc.ukans.edu (03/12/91)

How does one play continuous music?
I know how to do asynch sound, I know how to install a callback routine.  I
know that you chop your 'snd ' into "chorus" segments for variety.
So how do you tell a channel to play sound x after completing sound y?
If you use the buffer command, how do you get the pointer to your sound data? 
Could you specify a global pointer to the sound data and have your program
change this pointer from sound x to sound y outside the callback routine?  This
way the program could set which sound gets played (depending upon program
state)?
Thanks in advance.
