I have been trying to dial in a patch and about to pull my hair out over this clicking sound.
I am to believe it is coming from the AMP ENV as it is the only thing that seems to effect it. (changing filter cutoff changes it timbre slightly)
so: With all waveforms at 0, with both envelopes ADSR all at 0, full cutoff (LP), no resonance, no brute factor, 75% main volume, 0 ENV amount There is a VERY audible click coming out on key press. It is also audible when waveforms are up and the filter + amp has envelope + or -
This is a similar clicking sound I would expect from 0 release on an AMP ENV, but even tried putting full release does not change it.
