I am facing a crazy issue with my Zynthian, and I have no idea of the reason and how to solve it !
Simply said : after updating the firmware to last version, MIDI routing is completely broken.
All synths on all layers react to all MIDI channels
I thought it was related to a given engine, but this happens to all engines (LS, FluidSynth, etc…)
I have checked what goes out of the MIDI sequencer : everything is routed to correct channels, so the problem is really inside the Zynthian.
I made a simple test with a MIDI tracks playing only on MIDI channels 1 and 2 : result is awful, because synth on layer 1 reacts to MIDI events of channels 1 and 2, and synth on layer 2 reacts to MIDI events of channels 1 and 2 too !
I have checked the MIDI channel for each layer : layer 1 uses channel 1, and layer 2 uses channel 2.
What can be the reason of that strange behavior ?
