Project not extending past 390 bars

I’m having a problem where my measures just stop increasing at 390.4.3.11. I can’t see further, and the playhead stops there. If I start a new project, the last bar is 300. Any idea what might be happening? Max record time shows over 21 hours so it’s not that.


Change the length of the project in the Project Setup.

Thanks! I searched for “maximum measures”, “maximum bars” etc. in the manual but to be honest I wouldn’t have thought it’s connected to a manual project length setup.
