Hi @zynthianers!
Good news!
I’ve fixed the zyncoder library. I discovered that some MIDI messages were not processed correctly (active sense, time-code, etc.) by the MIDI router. I also have “filtered” SysEx messages until i can write and test the code to correctly address this messages.
With this fixes, keyboard-specific / fluidsynth problems are solved in my zynthians. Could you test the changes and see if your problems are solved?
You only have to update … or wait for the new “Omega” SD image that should be out in a few hours 
Regards!
