Subject: Shepard's tone as Max patch
Date: Thu, 21 Apr 1994 17:54:19 -0400 (EDT)
Mime-Version: 1.0

Here is the text form of a Max patch that implements stepping
Shepard's tones.  You may want to fiddle with the function in the table
to improve your results.

The patch requires a synth with 8 independent MIDI channels and works
best with voices that are very senstive to velocity changes.

Let me know how it works for you.

And now, laze and gelm...the code.
