Pressing L/R shows this screen:
This page allows you to route channels to the L/R bus (and hence the master STEREO output).
All channels (inputs, disk tracks, FX return and group outputs) can be assigned to the L/R bus.
The options here are simple - off (- - - -) or L/R.
As with the group assignments, you may find it easier to route channels to the L/R bus using
the control surfaces dedicated keys.
