Hi All!
I built Mark Media's DV/DT comparator-to-trigger circuit and fell in
love with it! Check out
http://www.wiseguysynth.com/larry/users/mark1/trigger.htm for the
description and schematic.
This will provide a trigger from nearly any kind of CV. Exempli
gratis - patch the sine out of the '320 to the trigger circuit. Send
the throughput to a '300 and the trigger output to an EG. The EG
will now send a CV to the VCF, VCA, etc., every time the LFO output
changes. Instead of just changing pitch, the synth produces a note.
I found this so useful that I made a dual version (using a TL074,
556, and double the other parts) and put two of these pcb's into a
module. There are three jacks per - in, through, and out - and my
module has 12 jacks. No controls are needed.
I'll share my pcb layout with anyone who asks. Those who know me
will understand that this is a hand layout on a single-side
copperclad board. As I've just finished laying out the resist on the
second pcb, I'll scan the foil side before etching it tonight. Those
with photo pcb capability can make a transparency from this. I'll
draw up a parts layout as well.
Happy constructing!

ps - the Supercontroller layout is finished and now being inspected
for errors. When my grandson let's me work, that is...
