Sounds good but I just discovered my JL Cooper Fadermaster does
handle NRPNs the same way as CC, and I think all controller boxes do,
and I think Atom mentioned that CC only have 7-bit resolution,
whereas I read somewhere else that NRPNs have 14-bit resolution. So
you might want to check to see if there might be a benefit in using a
few NRPNs?
