Surround Panning
Channel view in the Control app lets you access the surround panner. The Soft Knobs on the Dock map to the currently displayed
pan parameters.
To pan in surround:

1 Select a track assigned to a multichannel output path.

2 In Channel view, tap the Pan function block.

3 Drag the green pan dot to pan, or use the sliders on either side of the panner. Tap a speaker icon to jump the pan dot to that location.

When the current track is in any automation write mode, the pan dot turns red. When automation is off, it turns yellow.

4 Use the sliders (or knobs on the Dock or S3) to adjust other pan settings such as Divergence and Center percentage, as available.
