Thanks, Walt, but I don't think you were referring to the KN7K. The manual says that, provided the MIDI IN is set to PEDALS, it will receive MIDI messages on ALL channels (OMNI). I have tried resetting the channel to all others available, but with no result. I am beginning to think that there is a fault on my MIDI IN socket, as it won't receive from ANY MIDI device.
