This problem was reported on in September of 2013 and there was no response to it.
Keylab 49
FW ver 1.33
MCC ver 1.3.0.562
In split mode the pads send on the channel they are set for (default=10) AND on channel 1.I have the pads set for note toggle. If I change the channel to anything other than 1, I get that specific channel and channel 1. If I set the pads to channel 1, I get two channel 1 note on events ... The problem is not there when I turn split mode off. I have verified with MCC view midi and also with Midi-Ox.
