actually i have another question about the triggering. what exactly makes a CV gate trigger? can i make a kick pedal from an electronic drum set into a cv trigger? a midi sustain pedal? can i convert these kinds of switches into the proper CV signal?
It depends on the electronic drum. A normally open momentary switch can be a CV/gate signal if you connect one end to V+ and the other to the CV/gate in. A piezo might take some more circuitry.
