1. I want to get rid of CC4 on channel 10. 2. Then I want to take the E-2 notes on channel 1, take their velocity, and send that as a CC4 on channel 10.
(This is for a TD-6V drumset, which is weirdly sending a much better quality hihat control signal as the velocity of E-2 notes, than the actual CC4, which I don't understand, but I thought I will try to remap it to use it.)
