I have a USB MIDI based studio which includes two KeyLab mkII controllers (both on current firmware) connected to Ableton Live Suite 11. The tracks they are connected to have instances of Analog Lab V. Only one of the KeyLabs is able to control Analog Lab from the keyboard controls. The other one (second in the USB device order) can control the voice selection (meaning turning the big knob and pressing it changes the voices) but nothing shows on the controller's UI. Any ideas? I have tried putting both controllers on the same MIDI channel and also having them on widely separated and otherwise unused MIDI channels without any effect.
