Hello, I would suggest to control voltage with a microcontroler, which I succeeded after I got the [comport] external object. With PD and Basicstamp I can control the level of the dim that is attached to an electric circuit.

is there a way to read control voltage output in pd using a soundcard? what object should i use with adc~? can i simply plug the CV (maximum of 6 volts) to my soundcard or i need to buy an analog to digital converter?

if you need a quick and dirty hack to this end, you could always run your cv source into a vco, the oscillator into your soundcard, and the signal into fiddle~, tweaking things from there to clean up and map the results. it helps to make a quick "device driver" abstraction to this end. in the long run, however, i wouldn't stick with this. it's flaky and very cpu-inefficient for what it does. i just mention it because it can be thrown together in a few minutes if you just need a proof-of-concept demo of something.

best,
