I want to control the CV-in/expr-Pedal in on some (guitar) effect-Pedals by max. Those usually need a CV (control Voltage) of 0-5V. I could buy a midi-to-CV box, generate midi and "translate" it in CV, but I thought I could generate this directly in MAX. Expert sleepers have plug-ins which do that, using the audio output of (some) sound cards. Fine.
But what, in MSP, is a 0-5V signal???? A frequency? what pitch(es)? an amplitude? something else? how for exemple create a slow 0-5 sweep (which could then be the WWWWWHHHHHHHAAAAA of a Wha-wha)?
