If you read the fine print, you'll discover that the Sound Manager does not
implement 4-voice sound on a MacPlus, or an SE. You should probably just use
Sound Driver. It is what Hypercard uses to do telephone touch tones.

Another problem: The sound driver loads 1/60 sec of sound at a time into
video memory, synthesized from the parameters in the Sound driver parameter
block. If your rythym requirements make you divide time into finer intervals
than 60 parts per second, you'll have to give up on the managers and access the
sound buffers directly. Heaven help you when you want to be compatible with 
future machines.
