Are you layering elements or Parts?

Parts have individual volume control although you may need to edit the parameter rather than using the sliders depending on how the Performance is setup.

Elements have individual leveling too which is a different area of the interface.

Note: the above video assumes that sliders work for all Parts you are trying to change the relative volume for. There are corner cases where this may not be true and is not covered in the video.

One reason why sliders may not work is that there is something overriding the volume by means of a control matrix volume offset. The other thing you should look at is the Part you're having problems change the volume of and look at the Control Assign page looking for "Volume" as the destination.

Another reason why sliders may not work is if the Receive Sw (switch) for Exp/Vol is turned off for a given Part.

Reiterating what @Jason said.

Sometimes you will find an Element/Operator, Part or Performance Level Parameter value is "pinned" by a Control Assign (Mod Matrix).

In this case it will likely be a Element/Operator Level or a Part Volume.

This can often be the case when a Part is "borrowed" from a different Performance, and the Control Assign is left "orphaned" from whatever was controlling it originally (e.g. Super Knob, Motion Sequence etc).

You will need to search through Control Assigns at both Part and Performance (Common/Audio) Edit, and delete any that are assigned to destination "Volume" or "Level".

This is not a simple process to describe here. I wrote a short tutorial in this forum, you can search for it, or read through the Reference Manual.

Also, Gain can be pinned high in some other places such as EQs, Filters, and FX (Insert, System, Master). Watch out for these too.

[quotePost id=118292]When I create a new performance and begin to layer sounds, the Second sound that I layer's volume wont change. It's fixed at a very high gain level. Is there anything I can do to remedy this issue?[/quotePost]Yes, there is.

When you build a Performance by “merging” existing Parts, you will inherit the controller programming assigned by the original programmer to that Part.

You can avoid this by simply reviewing the Control Assignments made by the original programmer… Delete those that do not serve you. An understanding of how this happens (and why) is what follows:

The default condition is each Part 1-16 has its own dedicated Volume (Part) Slider… but for ease in performing you may find some Performances will opt to farm Part Volume to other controllers with more convenient access.

(Because you can control as many as eight Performance Parts simultaneously, using KBD CTRL, the Control Assign setup in the system, allows you to control how much each of them changes and in what direction they change in response to your controller movements. You’ll appreciate this when you get into adjusting several sounds, each by differing amounts, using a single controller gesture). But a simple two Part example will suffice to gain a basic understanding.

Example: take a look at the Performance “CFX + FM EP 2”
PART 1 = a CFX acoustic piano
PART 2 = an FM-X electric piano

When you initially recall and play this Performance, you will hear only the acoustic piano.
This is because the PART “Volume” has been assigned to the Assign Knob/SuperKnob system. It will appear to the uninitiated that Slider for Part 2 is not working as the control with influence over the Part…. Volume is determined by the position of the Part Assign Knobs within the Part’s programming. (The Part Assignment would be inherited if you attempted to activate it in your program).

The reason a programmer would do this is so you can “morph” (crossfade) from one to the other hands-free… ideal in this case because both of these sounds are typically played with both hands.

Think of the Sliders (Faders) as the sound engineer’s tool to adjust Part Volume (engineers have both hands available for mixing volumes)… but if both of your hands are occupied doing the actual playing of music, it maybe convenient to reassign the normal exclusive control over Part Volume to a physical controller you can move with your feet (for example).

A Part’s Assign Knob can ultimately be linked to the Super Knob… linking to the Super Knob in this case will allow the fade in of the Electric Piano (also the fade out of the Acoustic piano).

The Super Knob can be used as a real-time control and can be operated by plugging in an FC7 pedal into the Foot Controller 2 jack.

Here’s how to check and deal with Control Assignment.
Select the Part (very important) in this case, select Part 2
Press [EDIT] (the upper left of the screen will tell you that you are in “Part 2 - Edit”
In the screen (first column) tap “Mod/Control” > tap “Control Assign”

Here spread across 4 possible Pages are your 16 Control (Source/Destination) Assign sets.
Use the “Auto Select” (green is active) and the “Display Filter” to review what is assigned to each controller (Source)… spend time learning the navigation of this area of the synth.

You can review the Destinations by simply moving the cursor to each numbered Destination 1-16 (maximum of four Destinations are shown per Page)

On the Performance “CFX + FM EP 2”, Part 2 (the FM-X Electric piano) Destination #3 is where Part 2’s “Volume” has been assigned to Part Control Assign Knob 1 (which in turn is linked to the Super Knob)

While reviewing this Destination 3, you can Delete this assignment by simply tapping the box in the lower right portion of the screen “Delete”. This will return sole control of the FM EP’s Volume to its corresponding Slider (Slider 2).

You will also expect to find a Part Volume assignment when you select and explore the Acoustic piano in Part 1, which will fade out as the E piano fades in.

Final Note: When the Slider is not the sole Volume control for a Part, you can still adjust exactly how loud it is by using the “RATIO” parameter within the Control Assignment. The Curve, Polarity, and Ratio settings determine its travel from minimum to maximum (or vice versa).

Extra Credit:
“Choir/Str/PipeOrg”
Here as you advance the FC7 (Super Knob) you fade in another component. While playing the Choir slowly advance the FC7 (SuperKnob) to bring in the String orchestra… continue to eventually fade in the Pipe Organ. Each Part will react with its own individual response to your controlling gesture. (This, as you may note, is quite different from all controlled sounds doing the same thing in response to the control gesture).

In other cases, a Part’s Volume might be “biased” to the position of the MW… great for performing sforzando brass, or adjusting a pad’s volume versus the main sound, etc.

Hope that helps.
