maybe do a Discord Voice call

I don’t mind testing, but I only have the opportunity on Tuesdays and Thursdays.

Here is a screenshot of the SD-card control in the x32-edit software. 

Is there any progress on this?

I found some documentation that gives OSC information on the X-live cards. https://wiki.munichmakerlab.de/images/1/17/UNOFFICIAL_X32_OSC_REMOTE_PROTOCOL_%281%29.pdf (starting with "/-prefs/card" on page 51). Hope this helps.
