A couple of weeks ago I attended an Apple seminar. One of the speakers
discussed System 7.0. If I remember correctly, he said:

  The Sound Manager had been completely re-written.

  The sampled sound synth will handle four voices.

  Stereo will be supported.

  Sound compression is handled. I think he said de-compression is
  handled in real-time.

  I don't remember mention of the maximum sample rate.

Having programmed for the current SM (which was an exercise in SM :-|)
I am looking forward to the new release. Hope they got the bugs out, too.
