Beat cursor keeps jumping to the end of the project

and then the song stops. It’ll go about 5 or 6 measures, jump, and then stop. Anybody have a clue what this may be caused by?

Are the Locators backwards in that range?

No, not at all. They’re set regularly so I can loop sections when needed, and the cursor is jumping way past them by about 250 measures to stop. I only have about 24 measures recorded.


EDIT: it would seem that selecting 'Use System Timestamp" has fixed the issue.
