I got the MIDIpal to turn my two MKS50s into a mad 12 voice synth. It works exactly halfway because of the cruddy channel bit in the Roland SYSEX; notes go back and forth between the two units (great / amazing!) but SYSEX changes only go to the unit with the MIDI channel matching the one set in the app (alpha editor). MIDI omni ‘on’ only means that the unit receives notes on all channels, SYSEX changes are only received on the channel to which they are set. Can anyone think of a way that I can still get SYSEX changes to both units?
This is how I set it up:
ipad (ch2) > MIDIpal (ch2+ch3) > MKS50.1 (ch2) midi in > MKS50.1 through > MKS50.2 (ch3) MIDI in
MKS50.1 channel 2, omni 'off’
MKS50.2 channel 3, omni ‘on’
