When you have a Multi Part Performance, often a real-time Controller has been put in charge of Part Volume. For example, the “CFX + FM EP“, which is the first Performance, Part Volume is manipulated by the AssignKnob/Super Knob System. As you move the Super Knob you are turning the acoustic piano down, while you are turning the electric piano up.

This is not done at the MONTAGE mixer, but is done by assigning Part “Volume” to an Assign Knob, which is linked ultimately to the Super Knob position.

Here’s how to explore your Controller Assignments:
Press [SHIFT] + [HOME] to launch the “Motion Control” > “Overview” screen

Here you get a graphic view of the physical front panel Controllers (magenta) Assign Knob (green), Faders (amber), and Super Knob (blue)
The PART is initially set to COMMON, move it to each Part, in turn.
Set it to a Part # to view the Controllers active in that Part
Tap the box “Edit Part 1 Control Settings”
You will be taken to the “Part 1 - Edit” screen

Set the “Display Filter” = All
The screen show four Control Sets per PAGE
There are four potential Pages of four Control Sets
A Control Set consists of a Source (physical Controller) and a Destination (target Parameter)

You are looking for the word “Volume” as a Destination for this Part.
If Volume is assigned to a Controller (Source), then it is that Control Assignment that determines the Volume of the Part... either in addition to the Slider or in place of the Slider.

With this system you can Preset a mixer volume then swell or retreat the volume with the assigned Controller.
Sometimes the entire Volume has been farmed to the alternate Controller.

Think about it this way, the electric piano is plugged into the mixer.
The Fader is the mixer volume
The Assign Knob that has been put in control of the electric pianos output Volume is like the Volume Knob on the Rhodes itself.
The programmer has given the performer a dynamic control over the Volume (other than just the mixer Volume).

We highly recommend the series of articles on Super Knob programming to get this MONTAGE fundamental down.

Review your Control Assignments for each Part. If you wish to remove the Volume assignment, tap DELETE, in that Control Set, this will return exclusive control over Volume to the Fader.
