Let's say I have a module, controller KB, and Hammond SK1 with the SK1 on the bottom. The controller will have full control of L,R,and ACCOMP, with the SK1 sending chord control to the module, but no voice. I want the option to play all from the controller, or control chords from SK1 LH and lead from either.

This would mean two midi outs to one midi in. I have an old Midiman Merge 2x2, bit there would be a conflict in the LH voice where I would want it on the controller, but just the chord command on the SK1.

Maybe I need a switcher instead of a merger?
