Ever since I bought my Zynthian kit in June 2017 it has been very noisy on the encoders. I put it aside for some time because of that. Still it intrigues me.
As soon as I turn the encoders while playing a note the audio starts crackling and clicking. When no notes are played everything is fine.
I have tried changing the encoders, changing the location where I play, moving the encoders/screen away from the Pi, trying all different synth engines, even putting a 40106 in between to clear up the debouncing noise (which it did), but still there was plenty of noise on the audio out.
I’m using a v1 setup (Adafruit small screen) RPi3 B+, Hifiberry Dac+. I used the Gorgona Omega image which is configured for v1 kits. Triple checked my wiring and connections. In fact the Zynthian works like a charm except for the noise on the encoders…
Any tips would be more than welcome!
