I've got the Drum Sequencer on Midi Channel 1 and i'm trying to set some pads on the drums to send to Midi channel 2 so i can add another instrument to the drum rack. I'm using the Midi Control Centre, i press store to project 1 etc but the designated pads don't send. I've got a synth on Midi Channel 2 but it doesn't receive anything. How do i finalise the setting on the control centre or do i need an extra cable? Thanks.
