levels. When playback loops, you can click another control to continue making
adjustments to clips in other tracks. You can also make changes to clips in tracks you’ve

previous levels.

If keyframe recording stops before the end of a clip, the audio or pan level of the

pan overlay remains at the level of the last recorded keyframe for the remaining
duration of that clip.
