Just updated OB and updated to the newest version of pro tools ultimate.

ARmkii - same error
A4mkii - same error

Same issue, no change.

I’d also like to mention that I purchased my A4mkii something like 6 or 7 years ago under the promise from Elektron that I would be able to use it with overbridge and as a plug-in with any major DAW. The AAX plug in worked for me for a precious short time and then poof

I can still go the old route and send MIDI out and return audio in but that doesn’t give me the settings recall, and there’s no plug-in interface.

oh well. Maybe someday
