I noticed that when I control the M32’s filter cutoff freq via CC1 (modwheel), I hear each individual MIDI step, I don’t get a smooth sweep - is there any external slew that I can use (Eurorack format) to smooth out the modulation?
Make Noise Maths is a slew processor at heart, among many other things. Function also works if you don’t have the HP. But really pretty much any slew processor should work.
