I have a midi keyboard driving Zynthian on a Pi 5. I am using SetBFree and controlling the rotary / Lesley effect from the mod wheel CC1
I find that occasionally the rotary effect will start doing continuous random things without my input. Disconnecting the midi keyboard does not change this random behaviour.
If I look at the Midi Log I see continuous random CC1s and CC67s messages. This behaviour also starts to cause XRun warnings on the Zynthian display
The problem appears to be SetBFree itself. If I go to Patchage and disconnect SetBFree midi out, the problem goes away. So I assume that for unknown reasons SetBFree is receiving these CC messages, then passing them on to its output. Because of the way its wired in the ZynMidiRouter it then gets those CCs returned and goes into a loop. Dont know why it doesnt do this continuously
So deleting this connection is a workaround, but if I reboot Zynthian it returns with that connection restored and therefore susceptible to looping the CCs
How do I make this workaround permanent ?
