The firmware is 3.7.6.
Set MIDI ch 5, and set Poly Cinematic's MIDI ch to 5 as well (hold SHIFT and turn resonance).
Does not respond to all triggers entered on MIDI ch 5.
Sometimes responds.
When triggers are entered on other MIDI ch and the triggers overlap, sound plays normally.
NOTE does not seem to be affected by other MIDI ch.
Currently, I've managed to get it to work properly by entering all triggers on available MIDI ch.
I have confirmed that the MIDI ch is not Omni.
