I want to control another rack synth's cutoff and resonance from my P6 acting as a midi controller. If the LPF Cutoff on the rack is Midi CC#33 but on the P6 its Midi CC#109 (I know thats not what it is, just an example) how and where do i get them on the same page so when i twist the knobs on the P6 The rack module responds correctly. Do both units have to be configured using a computer? Thanks!
