Or how about driving the 700 at audio rates - this does some nice
waveshaping. There's been some discussion elsewhere about using a
mixer with different waveshapes on the input. Hard sync is also an
entire interesting world of waveshaping.
I think I'll start the journal rolling by posting a patch that does
something like granular synthesis. A one-pager in Word format. If
somebody has the ability to convert to PDF, that would be cool.
I'll do it tonight when I get home...
