RE: [motm] (was Blacet-MOTM adaptor) Pulse divider

2000-06-20 by Brousseau, Paul E (Paul)

Hmmm... here's a brain hiccup:

Audio In -> Pulse Divider In
Pulse Divider Out -> EG Trigger (gate?)
EG Out -> VCA Trigger
Audio In -> VCA Audio In
VCA Audio Out -> Audio Out

I think you'd get a rapid-fire shuttering effect on the audio based on the
frequency (and amplitude?) of the signal.  Play with the envelope settings
and the pulse division to get different shutters.

Thoughts?
