I bought this Keylab just last month.
When I record on Cubase, some notes just randomly gets stuck on “Notes ON” as shown on the picture. When I play that note it only records the “Note ON” but not “OFF” .
Does anyone have the same issue or know how to fix?
Then it look like a DAW related issue of some kind. Perhaps even a usage issue.
I can suggest you contact your DAW support.
Perhaps others have the same issues with other controllers in that DAW?
Hanging notes are annoying. You can try to notice, if it’s when doing a certain thing.
As you say, then the issue seem to be the note off message is missing. The question is why? That’s not easy to guess.
