I'm trying to use the keylab with two setups simultaneously: USB connected to PC provides energy and midi notes in to Ableton AND Midi Out port sends midi CC (knobs/faders) to a pedal that have midi input... But the pedal don't receive the midi in properly, the CCs keeps jumping. That issue don't occurs when the keylab is using the usb just for energy (with a normal USB 5v power adapter), so I assume that is some issue with the USB midi in/out.
Someone have tryed to use it that way and/or have a solution?
