There are two main philosophies on setting up a controller with RMX:
SINGLE PART STYLE
Controlling a single Part with your controllers assigned to different Part parameters (Cutoff, Resonance, LFO rate, FX sends, etc).
MULTI PART STYLE
Controlling multiple Parts with your controllers assigned to the same parameter on each Part (Mixer level 1-8, Pan 1-8, Solo/Mute 1-8, Cutoff 1-8, Resonance 1-8, etc.).
Since RMX’s Part / Channel / CC assignment is so flexible (see Key Concepts), it’s important to have tools to manage the behavior when the incoming MIDI channel of the controller is changed, so that you don’t have to duplicate every assignment for every Part and Channel. Cloning and Omni mode are useful for these purposes.

CLONE PART 1 CONTROLS
This menu item copies all the non-omni mode MIDI Learn assignments from Part 1 and applies them to Parts 2-8. This is a huge time saver as it saves having to manually assign 7 more identical Parts if you want the same assignments for every Part. A warning dialog box appears to confirm that you wish to do this.
NOTE: Notice in the below picture that CC 4 is controlling two different RMX parameters at the same time—the Power Filter Drive and Power Filter Width. You can assign several RMX parameters to a single external controller for dramatic changes with a single slider. This is true for buttons as well. For example, you can assign 5 Part Play buttons to a single external controller button.
MAKE CONTROLS OMNI
RMX is MIDI input-channel-sensitive when MIDI Learning—it can distinguish between a button transmitting Ch 1 and the same button transmitting Ch 2. Selecting this menu item allows all non-cloned MIDI Learn settings to respond to any incoming MIDI channel (i.e. MIDI Omni mode reception). This is useful when you want RMX to respond to an external control regardless of the current incoming MIDI channel.
