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
