What is the “input” mixer?
To have the VS be in the “input” mixer mode, press the FADER [EDIT] button until it turns orange. The input mixer is where you assign your physical input devices (which plug into the back of the VS) to a recording channel/track. You can route input devices to multiple tracks. By default, physical input 1 is assigned to track 1, physical input 2 is assigned to track 2, etc. One or more physical input devices will be the source, and one or more tracks will be in the record condition, and these will be the destination tracks.
