you can do this in impact for drums. I have my mpc one connected and i click the pad i want to change and then it shows 1st and 2nd note assignment at the tope right on Impact XT. I click the first note and then i click the pad on the MPC that i want to map to the corresponding pad. Instantly it works. The Problem, i haven't figured out how to save these assignments as a map so i can quickly access them depending on what controller i'm using (mpc one, atom sq, kontrol s49, akai advance, m32, etc.)
