Scrubbing Checking Scrubbing, or typing Command-r, allows you to hear MIDI notes in the Graphic Editor or Event Editor windows by dragging the cursor back or forward in time over notes. Choose Scrubbing from the Switches menu, then drag the cursor over the range you want to hear; you’ll hear the notes as your cursor passes over them. Scrubbing supports both MIDI and digital audio tracks. Note: In order to scrub, Audio Region Editing must be turned off (Shift-Command-A). Note: Selecting in the Graphic Editor Window must be done from the time line when scrubbing is enabled.
