Most likely yes. There is a system to offset parameters and Presets may utilize this system to use Super Knob or other controllers to offset volume. When this is done often the volume parameter gets "saturated" beyond what the faders can do.

You would take a look at "Mod/Control" -> "Control Assign", set the filter to "All", then scan through all of the pages to find "Volume" (in this case it's the thing you're struggling with) as a destination. Touch it and you can see under "Source" what the source controller is. If it's an assignable knob most likely Super Knob is tied to this assignable knob.

You would do this for each Part you're noticing the behavior with.

There's an option to delete the assignment if that's not what you want.

OK, now I'm in WAY over my head here! This is a performance I got with a library I bought.

On Page 1
For Part 1:
Destination 1= InsB LfoSpd
Destination 2= InsB L/R Dpt
Destination 3 = Volume
Destination 4 = InsA EQ 3 Gain

For Volume :
Source = AsgnKnob 1

for Part 2:
Destination 1= InsB L/R Dpt
Destination 2= Var Send
Destination 3 = Volume
Destination 4 = InsA EQ 3 Gain

For Volume :
Source = AsgnKnob 1

Everything else is the same. What happens is when I press ASSIGN and turn the first knob, it sounds like the panning is more pronounced. But the knob is backwards. When I turn it CW part 1 volume goes down, CCW part 1 volume goes up. When part 1 volume goes down the panning is more pronounced.

Anyone want to take a stab at explaining what's going on here? 🙂

Thanks,
Fred

Most likely Super Knob is tied to Part 1 and Part 2 assignable knob 1. One is set to go from max to min volume and the other set from min to max volume. Rotating the superknob allows to "morph" between the two parts. Having all of one, all of the other, or a mix between depending on the superknob position.

If you don't want this, delete the Volume destinations from Parts 1 and 2.

Now your sliders are in full control.

The only final cleanup is considering how much of Part 1 and Part 2 you want when you first load up your custom User version of this Performance. Just set the sliders to the mix you want and [STORE] this.

Bill, it comes from experience with working with the gear. What is described is a classic morph using Super Knob. This is inferred given the source for volume is a Part Assign Knob (#1) and feedback that one knob goes "backwards".

In order for Super Knob to "reach" a destination parameter in a Part - it must always be "tied" to two sets of Assignable Knobs. The Common/Audio level and then those knobs are tied to the Part Level Assignable Knob(s). The knobs cascade to a destination parameter.

All Super Knob connected parameter changes you could individually control by selecting a Part, make sure [ASSIGN] is pressed (so the knobs are in Assignable Knob mode) and then twist the one knob that is tied to the destination parameter.

Yep, you are correct. After reading Jason's post from the link you provided I see that it's ultimately the Super Knob that is controlling everything. When I turn the SK it does exactly the same as when I turned on ASSIGN and turned knob 1.

So, I think what's happening if I'm correct is that part 2 has a strong auto pan effect and part 1 doesn't. By turning the SK and lowering the volume for part 1 you get more of the effect. Does that sound reasonable?

No exactly sure how it's doing that but I'll dig deeper.

Taking a side-bar here for anyone's benefit wanting to learn more:

Take an example of a "morph" Performance "CFX + FM EP 2". Make sure you pick the "2" Performance since this one has less Parts and is therefore more straight-forward. Now spin Super Knob to the full clockwise position and you will see only one instrument has maximum volume and full counter-clockwise the other instrument will be at maximum volume (and, at these positions the opposite instrument will be silent).

Full CCW = Piano only
Full CW = FM EP only

When you have Super Knob spun at full CCW, Part 2's slider which controls the FM EP volume will not give you any volume for Part 2 since the offset volume is saturated and is offsetting -127 (at least). Likewise if Super Knob is full CW then Part 1 is silent and the slider will not give you any volume as now the offset is at least -127 for Part 1's volume.

Ok, set Super Knob to full CCW so now only Part 1 is sounding. The slider works fine for Part 1. Leave the slider to maximum so we keep maximum volume. Now press Part 1 to select it. No need to pick a menu item. Make sure the [ASSIGN] button is lit - it should be by default. Spin Knob #1. This is the assignable knob controlled by Superknob through another assignable knob. You'll see it's "backwards" where full counter-clockwise is max volume and full clockwise (of the Knob #1) forces the piano to silence. You've temporarily "taken over" the control of the Part-level knob that usually Super Knob has control of. You can manually adjust parameter destinations this way apart from Super Knob even though Super Knob also has control of this knob (and others at the same time in this example).

Hopefully walking through this will help illuminate why the OP's description is consistent with everything I've wrote in this thread (including past responses).

"Backwards" isn't a problem. You have all kinds of places you can form a reverse relationship between Super Knob and the target parameters.

At the Super Knob Common/Audio level you can spin the Common Assignable Knobs either in the same direction as Super Knob (low value on top, high value on bottom) or in a reverse direction (high value on top, low volume on bottom). This is a feature.

Whilst on this capability, one other common cause of inflections and reflections:

the Ratio feature being able to go below zero for all Assignments means the Resultant values can be reverses, too.

So one way to make a concurrent ping pong is to have a driver control for volume on two "stereoed" parts (one hard Left, one hard Right), inverted on one of them, thanks to a negative ratio. Then oscillating that driver value switches them "on and off" in volume alternatively, giving a sort of ping pong effect, that can blend at the rate of the change of the driver's animation (usually the SuperKnob or a Motion Sequencer moving back and forth). This is an overly complex way to achieve this, but if you wanted to do other things at this rate, then the "panning" of these parts can piggy back on this driver's animation to ensure that everything's synced.

Oh dear, not again!

@Phineasphred...

all your woes can be solved in under a minute. @Jason has already described the solution but it seems to have become obscured by forum banter.

The problem is that the various "Part Volume" parameters have been "Assigned" in the Control Assign sections of the Synth (more on that at the end).

Your quick escape route is thus...

Edit Part 1 - MOD/CONTROL - CONTROL ASSIGN

Set Auto Select OFF
Set Display Filter to "ALL".
Page through the Assign Destinations (Destination 1, Destination 2 etc)
Where ever you see Destination Set as "Volume", click on it and Delete it with the bottom right Screen button.

Repeat for PART 2, PART 3 etc

Now go to HOME, EDIT (Common/Audio) - Control - Control Assign.
Auto Select OFF
Display Filter ALL
Page through and Delete Destinations where you see "Volume".

Once you have done this, your Sliders will work again as you expect.

I recommend, going forward, that you spend some time studying and experimenting with "Control Assign" sections of the Reference Manual. This is genuine well intended advice. So much of what you hear in the Auditions is based on Control Assigns. These, in turn can be controlled by the Super Knob, and then by the Motion Sequencer. It is a "network" of associations. It confuses a lot of users on a regular basis. It isn't hard to understand once you've tried creating a few, but you do need to familiarise yourself with it to get the most from your MODX.

Beware... assigning Part Volume or Element Level or Operator Level to a Control Assign will "limit" the functionality of the Sliders.

I prefer to use the Sliders to mix Volume & Levels. That's just me. I feel like I have greater control and fine adjustment. So I avoid assigning Volume unless I absolutely need to for a specific effect.

Is this issue one and the same? Are you conducting this test with headphones on? I can tell more clearly when I'm wearing headphones. https://yamahasynth.com/forum/volume-has-no-effect-on-part/ octordle
