Allow knobs to send CCs separate from switch CCs

so you can have the switch CC do one thing on one channel and have the knob control something else on another CC and/or channel. 8/10/12 knobs is so much midi control potential in one spot, with 8/10/12 switches right below them QC is the potential absolute most capable midi foot controller that exists. it would be a perfect match to control an AFX3 or helix with the switches for scenes/bypass and the knobs for global/parameter controls
