In learning to edit a Performance in my MOXF8 I came across the iPad app "Performance Editor Essential". It looks like an interesting app but nothing for a Windows application. Is there a Windows "Performance Editor Essential" program?

No, there is not.

If not, is there something else to visually navigate the Performance editing process, a video to help me with creating/editing a Performances?

Editing Performances is easy to do using the on board screen and functions. The App provides nothing that you cannot do on the front panel of the MOXF (except for the XY Control Pad).

I've successfully created a few Performances and stored them. I'm just now stuck on how to edit them such as adjusting the mix etc as demonstrated in the iPad app.

To adjust the Mix of your Performance Parts, on the left front panel press both [KNOB FUNCTION] buttons, simultaneously — this sets the top four Knobs as side-by-side Volume controls and the bottom row as side-by-side Pan controls, for Performance Parts 1-4.

Thank you Bad Mister. Very helpful. Are these instructions documented in the MOXF Owner's Manual or elsewhere?

Please see the following article from the MOXF “Learn” section of this site:

MOXF Physical Controller’s and Destination Parameters

Hope it helps.

Thank you!
