I love this sort of thing! I've read some stuff recently about how in
the '70s Suzanne Ciani would run her Buchla system for days at a time,
programming it to compose and play endless compositions.

I just finished a "random sequencer" patch that uses the knobs on the
A155's bottom row, instead of the toggle switches. Instead of
switching a step on/off, you adjust the knobs to set the *probability*
that the step will produce a trigger.

I've been using this in conjunction with random LFO's patched to the
A156 for pitch CV. I've gotten some interesting A100-generated
compositions so far, but I'd like to explore more sophisticated
machine-generated music techniques that can be realized on the A100.

If anyone has any more suggestions, I'd love to hear them. If I
discover anything more about this that's interesting, I'll post about
it here.
