What are all the ways to set an Performance Level Assignable Knob to control the Reverb Setting of a Part within the Performance?

I'm presuming there's more than one way to do this, and that there's at least one of these ways that's somewhat discoverable.

But it's not jumping out at me as to how this is done, in any way, let alone in an easy and rapid manner whilst programming/designing a sound.

The parameters that can be targeted from the Common Assign Knob level of the architecture differ from those available to a Part’s Assign Knobs. There are 8 Common Assign Knobs for the Performance - they default to being “linked” to the Super Knob. Each Part, 1-16, has 8 Assign Knobs.

You can understand the Reverb block as one of two System Effect processors found on the upper Performance (Common) level of the architecture.

__From the Performance Common Control Assign screen (from HOME press [EDIT] > touch “Control” > “Control Assign”), tap “+” in an available DESTINATION box to add an assignment… tap the parameter that appears to see the pop-in menu of all the options; if you select “REVERB” as the Destination you can then see the list of available parameters you can adjust within the currently selected Reverb Type (the number may vary with Type selected). Because this will adjust the Reverb processor itself, changes here will affect all Parts using the Reverb Effect. (ie, in ‘common’). These upper Performance Common Assign Knobs default to being linked to the Super Knob movement (this is programmable).

__From the Part Edit, Assign screen (“Mod/Control” > “Control Assign”) the only parameter Destination selectable from this level of the architecture concerning the Reverb block, is the selected Part’s SEND amount. “Rev Send”. This being the only Part specific parameter.

A parameter assigned to a Part Assign Knob can be adjusted directly, only when you *select* that Part… unless you link it with the Super Knob… you do so by utilizing one of the 8 Common Assign Knobs on the upper Performance Common level of the architecture.

_The Super Knob is always available. No special button need be pressed, no special conditions need to exist. The Super Knob can address any Part via the Assign Matrix.
_The upper level Common Assign Knobs share the fact that they can address any of the 16 Parts, yes even Parts you are not KBD CTRL’ing, but the [ASSIGN] button must be lit and on the MODX, you must be in a Performance Common area.

Linking a Part Assigned Knob to the Common level is done by tapping the shortcut box “Edit Common Control Assign”
Simply “+” a Destination targeting the Part # and the Part #’s Assign Knob #.

In general, if you want to have real time access to a Part parameter, without having to directly selecting the Part, you can link that Part’s Assign Knob with an upper Common assign Knob.

Say, for example, you have piano layered with strings and a Pad… 3 Parts, 1, 2, 3, respectively.

You want full time access to Rev Send on the piano
You want full time access to Volume on the strings
You want full time access to Cutoff on the pad

Each Part would be individually programmed on the Part Edit level
In Part 1 AssignKnob 1 to control “Rev Send”
In Part 2 you assign Part 2’s AssignKnob 1 to “Volume”
In Part 3 you assign the pad’s AssignKnob 1 to “Cutoff”

By linking these assignments with the upper Common level, you make them available from the MODX HOME screen… without having to select each Part in turn to get what you need. (Basically, you assemble the most essential parameters from each Part on the Performance Common level of the architecture. If you have multiple parameters from a specific Part you have the ability to assign multiple things to each Common Assign Knob).

On the upper Common level of the architecture you would
Common Assign Knob 1 - - -> Part 1 Assign 1 > Rev Send
Common Assign Knob 2 - - - > Part 2 Assign 1 > Volume
Common Assign Knob 3 - - - > Part 3 Assign 1 > Cutoff

Say you only want the strings to follow the Super Knob, you can unLink Common Assign Knobs 1 and 3… so only the string (volume) will change in response to your FC7/Super Knob.

I get all of this, the architecture.

But how do I, knowing this, actually set the Rev Send value of a Part so that it responds to one of the Performance Level Assign Knobs?

What are the user steps, the mechanical operations, of doing this?

Select the Part to edit.

Navigate to the reverb send parameter and touch that parameter so it's highlighted.

Make sure the [ASSIGN] button is lit (to right of assignable knobs)

Press [CONTROL ASSIGN] then (EDIT: adding ...) press and hold the [COMMON] button which, on the M, is next to the [CONTROL ASSIGN] button while turning the desired assignable knob you want to assign to reverb send.

Caveat: if all destinations are full the [CONTROL ASSIGN] button won't light up brightly which will block adding another assignment. Delete an existing assignment if this is the case.

This only does a Part Level Assign Knob assignment.

I assume the poster has a MODX/MODX+ as this is the forum heading.

One Method: Given so you understand what is actually happening
You first need to assign a Part Assign Knob to control Part “REV SEND”
Then you can link that Part Assign Knob to the the upper Performance Common Assignment level by pressing the shortcut button “Edit Common Control Assign”
This takes you up to where you can link the Part Assignment you made to the movement of the Super Knob via one of the Common Assign Knobs. This is longhand - it is what you are doing at each level. It is what you need to know to understand HOW it actually works.

As I said:
From Part Edit,
Touch “Mod/Control” > “Control Assign”
Activate the “Auto Select” (green)
Move the Part Assign Knob you wish to use as the “Source”
Touch “+” in the first available DESTINATION box
Tap the default entry to open all the options for Destination (target) parameters
Select “Reverb” > “Reverb Send”
Press [EXIT] to close the options field
Near the bottom of the Control Assign screen touch “Edit Common Control Assign”

This takes you to the Performance Common level of the architecture.
Add a DESTINATION by tapping the “+”
Again tap the default assignment to open the option field
Set it to “PART #” > Part # Assign #
where the Part # is the one you assigned Rev Send, and the Assign # is the Part Assign # you used for “Rev Send”.

Alternate Method: The Shortcut — very quick
Navigate to the REV SEND parameter of the Part you wish to affect. It can be found in several locations….
This can be by *selecting* the Part, press [EDIT] > “General” > “Part Settings” > move the cursor to highlight “Rev Send”

Or an alternate method to the REV SEND: from the HOME screen, touch “Mixing” in the first column
Find the “Rev Send” for your Part on the mixer, move the cursor to highlight it

Quickest Assign:
When you *highlight* an assignable parameter (wherever you find it) the [CONTROL ASSIGN] button will glow indicating you can quickly assign a control using a Controller Learn feature.
Press the [CONTROL ASSIGN] button > you are asked to input the control you wish to use for “Rev Send” the highlighted parameter

Move the Super Knob… if you have an available Part Knob and an available Common Knob, you will have successfully assigned Rev Send of a specific Part to the Performance Common area… both the Part Knob assignment and the Common Knob assignments are made automatically using this method.
A drop-down item will briefly appear telling you which Common Asgn Knob is set to engage which Part Asgn Knob.

If you do not have an available (free) Part Assign Knob and an available (free) Common Assign Knob, the system will not automatically make the assignment for you. You will receive a message warning you of this.

You must manually stack multiple assignments to a Controller — this forces you to review it before signing off on it. Just because a Knob is not free does not mean defeat, it simply means you must make the assignment and make the necessary adjustments to the parameters that share a knob… for example, are direction of change correct, is the distance of change make sense for parameters sharing a controller.

Once assignment is made you can further tweak how it is applied… Curve Type, Polarity, Ratio, Parameter 1 (or sometimes 2) settings that help Shape the Curve Type. This is a detailed way to create the DEPTH or application/direction of change.

To avoid conflicts, when working on a Factory Performance or anybody else’s programming, it is important to review all Controller Assignments before proceeding with your own custom Control Assignments.

This will avoid making a duplicate assignment or worse, having two assignments fighting against each other. In your case it is possible that Rev Send may already be assigned to a different controller, it pays to know exactly what the original programmer was doing. Perhaps you only need to change control from one Source (Control) to a different Source setting.

Review the assignments by setting “Auto Select” On (green) and reviewing all control assignments— you do so by setting the “Display Filter” to “All”. There are 16 possible Control Set assignments: they are numbered DESTINATION 1 thru 16.
4 per PAGE, 4 possible PAGEs.

A Control Assignment can be removed by tapping the “DELETE” box in the lower right corner of the screen.
