CV-to-MIDI

One easy hack I have done to do this is to buy a Peavey PC1600 fader box or
equivalent...open it up and find where the wiper on all the linear pots goes
to, as I remember they all feed to a header on the peavey. By cutting the
traces just before the header you can put a normalling subminiature mono
jack for each of the traces you have cut. ( You might want to put a 5 volt
zener across the jack for over voltage protection.)

When nothing is plugged into the sub-mini the fader box functions normally,
but when you plug in the 0-5V thermin thingy or whatever it is it acts like
a fader on the peavey. From the operating system on the peavey you can
define it as whatever, note-on, controller, pitcbend...etc

hope that helps...
