Last night it happened to me. I upgraded the A4 to OS1.1b a few days ago. I’d been working on 2 patterns for a new project, being careful to save everything - at the pattern, kit and project levels. I powered up and the kit on one of the patterns had changed. Track 4 had a default sound in it, although all the trigs were there in the track playing the wrong sound. And Performance C config had also been wiped - even more annoying because that was bespoke and not just a selected sound!
Is this going to mean we can’t rely on our kit to have all our ‘content’ ready for a gig??? Or did we all have it coming for installing a beta of the OS?
