Here’s a fun one. I made a backup of my projects on my computer, then restored them to the op-z shortly after. The backup seems to be a save state from several days ago (even though it was actually from this morning), so for example I had a project with six patterns, but only four of them were there. In this case, the last two patterns were just duplicates with some punch in effects so I didn’t really lose much, but the implication isn’t great.
What’s weird is that those patterns had been there for several power cycles, they weren’t that recent.
Also, something that I can’t find an answer to in the manual - how do I save pattern chains? When I change projects they just disappear, so presumably there’s something I should be doing to get it to remember, but seems odd that it isn’t just automatic.
