I'm using Ableton Live 10. The B-3X upper manual is set to midi channel 1 and the lower manual to midi chanel 2. I'm transmitting on midi chanel 2 from my controller keyboard yet it's playing the upper manual not the lower. If I switch the B-3X lower manual midi channel to 1 then it does play the lower manual even though I'm transmitting channel 2 from my controller (also set the ableton track to only receive channel 2). So no matter what channel comes into ableton it seems to be telling the B-3X plugin to play midi channel 1.
Thanks for any help.
