[PD] converting incoming audio/voltages into CV for Eurorack modules

[Simon Iten]

yeah it is. but be aware (once more) that one very high pwm frequencies you will loose some resolution.

Generating trigger signals (e.g. for envelope generators) is really easy because you can directly use the digital outs. CV for modulation is a bit more tricky because you have to smooth the PWM outputs of the arduino with low pass filters. I found that using two RC circuits in series (with C = 1 microFarad and R = 3,3 kOhm) works decently for pins 5 and 6 on the Arduino Uno (pins 9, 10, 11 have a lower PWM frequency and therefore might need a lower cutoff frequency). I'm thinking about trying out some multichannel DACs with 10 or 12 bit because PWM on the arduino is only 8 bit. DACs also operate at a much higher frequency so smoothing would be much easier.
