In the Mix and Edit window, multichannel Panner Grids are displayed on tracks that have multichannel track or send output assignments.
The Pan Location cursor follows your movements as long as you hold the mouse button. Movements are scaled so that, once you click to “grab” the Pan Location cursor, you do not need to limit your movements to the small Track Grid area.
The Pan Location cursor is green when the track is in Automation Read mode, red in an Automation Touch, Latch, Touch/Latch, or Write modes, and yellow in Automation Off (or Automation Suspend) mode.
