Suonobuono Polyvera - Super 6 as a midi controller not working!

I got a Polyvera but the Super 6 doesn’t work as a midi keyboard.

I got sound out of it twice, seemingly randomly. Once the note latched/hung. The other time an arp patch played, I couldn’t add any new notes, and once I disengaged the arp button on the Polyvera it stopped and it wouldn’t play any new notes.

JDXI worked fine as a controller for it.

Super 6 worked flawlessly as a midi keyboard for all my other modules/desktops.

Is there anything I can try while the dev works on a fix?

How is the midi wired?

5-pin midi.

There was a USB option in settings but I didn’t have the cable on hand.

I will try that, at least.

The dev wrote back and said hopefully a fix next week so that’s good.
