The USB monitor doesn't have a pan option that's independent of the rest of the system. The panning is handled at a level before sending out to USB - so you would be looking for pan that's applied at the Performance level.

In other words - if you had the signal routed out your main outputs (analog) - then you'd hear the same panning going on there too (or headphones).

Make sure you first check the Mod/Control->Control Assign menu and make sure there's not a destination set that would affect panning. If there's a knob or controller that can affect pan - then perhaps you can set the controller value by a MIDI command.

If pan is off-center, it's likely the Performance that's programmed to do this.

You can also look through your mixing screen to see those pans. Although it won't show you offsets.

You can also press the [MULTI] button until "PAN" is lit and look at the offsets set by each knob.

What I'm getting at is that you look at the "normal" places for pan settings. There's nothing special or unique for the USB outputs (Digital) Main L&R.

I'm sure you'll find these Performances have something that is programming pan to be off center.

Can you start off with the "worst" example of the problem you are seeing? Give the full Performance name from the library.

"MFMX Krazy 8 HarmSwp" is the name of the first Performance in the Library. If you press [MULTI] until "PAN" is lit - you'll see PART 1 is panned left (L36) and PART 2 is panned center. Other Performances, for example, in the series have PARTs panned hard right/hard left. I haven't skimmed through them to see if there are pan offsets set elsewhere than from the top level / mixing level.

It would really be best to just pick one of the Performances you're seeing as "buggy" and we can help walk through where to discover - on real stuff (the same Performance) - the pan settings.

There's not really an Init performance inside the Library. The Live Set has a "pointer" to the AWM2 Initialize Performance - but this isn't an "Init" Performance contained inside the Library itself.

Here's an example. I'm playing audio using the Line (MONTAGE) device in Windows, and the device balance is centered. All performance selections are made via category search.

1. Select "Init Normal (AWM2)" from the presets. The computer audio is centered as I'd expect.
2. Select "MF.HCM2WrmSusUD4eOP7" from the library. The computer audio is still centered as I'd expect.
3. Select "Init Normal (AWM2)" again. The computer audio is now panned to the right. The audio from the performance is centered, however.
4. Select "Init Normal (AWM2)" yet again. The computer audio returns to being centered.
    

Ok - thanks for that. I had originally installed the library from article #1, which is a different set of Performances altogether. For the rest following, "MF.HCM2WrmSusUD4eOP7" is contained within MannyFMXplr.X7L and is available for download from the article: Manny's FM-Xpert #3: "It's Just a Phase, Man. " ( https://www.yamahasynth.com/synths/mannys-fm-xpert-3-its-just-a-phase-man )

... so I'll have to check this later after installing and taking a look.

The USB Audio Input can, indeed, be panned and is being panned by the current Performance setting.

This takes place when returning audio to the MONTAGE via the USB “Digital In” and can be accessed as follows:
From the HOME screen:
Press [EDIT]
Touch “Audio In” > “Mixing”
The bottom half of the screen contains the “Digital In” parameters.
Here you can control the “Input Mode”, “Volume”, “Pan”, “Dry Level”, “Var Send”, “Rev Send” and “Output Select”

The Pan is set to “R36”
This is a setting that is storable on a per Performance basis.

You can also see this same parameter setting by navigating from the HOME screen:
Touch “Mixing” > the default mixer view shows you the “Part 1-8” view, the two Audio inputs are on the right side of the mixer, Audio In and Digital In.
Again, you can see the “Digital In” has been stored at “R36” in all Performances in this Library.

More to this...
At first, it appeared that this simply was an overlooked parameter setting — since when building a Library often you are building upon your own previous programming, if you ‘copy’ settings from one Performance to the next — a rogue setting like the “Digital In” being panned to “R36” could easily be inherited into all of your programs... and then when transferred to a Library, gets installed that way...

This setting does not appear in any of the Factory Presets, nor in any of my Init programs.

Upon further inspection, this same anomaly seems to appear in several Libraries, not just Manny’s FMXpert data. The fact that it is ”R36“ in all cases seems an impossible coincidence.

But this does not appear in all Libraries. Nor in any new Libraries just created...

You are reporting that selecting an “Init Normal (AWM2)“ maintained or recalled this Pan setting when selected via “Performance Category Search” — I have not been able to verify that... but this maybe how it gets into some, but not all, Libraries.

At any rate, we now know where it occurs, we’ll let engineering figure out when and why.

Thanks for reporting this.
