Editor window only showing limited part of one track: how do I fix this? Garageband 10.2.0
Recently, for some bizarre reason that I can't figure out, the Editor tab/window is only showing a specific part of one one track. I've clicked track, region and tried all sorts but I can't change it. It's so frustrating as I can't edit my vocals accurately as I can't see the waveforms etc.
It feels like I've somehow locked this window with a region on a particular track, but I don't how I've done that nor how to rectify it.
Please please help,
Micah
