GarageBand Move regions in the Tracks area
You can move regions to a different point in the same track, or move them to another track of the same type. You can move an audio region to another audio track, for example, but not to a software instrument track, or vice versa.
When you move a region, it snaps to the nearest position on the Tracks area grid.
Move a region
Do any of the following:
Drag a region left or right in the Tracks area to move it to a new point in the same track.
Drag an audio region up or down in the Tracks area to another audio track.
Drag a MIDI region up or down in the Tracks area to another software instrument track.
