All mapped output busses of the same format
(such as stereo) are all assigned to the same out-
put path. For example, you can assign all stereo
output busses to output path A 1–2.
To map all output busses of the same format to
one output path:
1 Do one of the following:
• Shift click to select contiguous Output bus-
ses.
– or –
• Command-click (Mac) or Control-click
(Windows) to select noncontiguous Output
busses.
2 Option-Shift click (Mac) or Alt-Shift-click
(Windows) the Mapping To Output selector for
one of the selected Output busses and select an
output path (mono or stereo).
Only the selected mapped output busses of the
same format (such as stereo) are assigned to the
same output path. For example, you can assign
only the selected stereo output busses to output
path A 1–2.
To map all busses of the same format to unique
ascending output paths (cascading):
 Command-Option-click (Mac) or Control-Alt-
click (Windows) the Mapping to Output selector
of the top-most output path and select the first
output path.
All busses of the same channel format are auto-
matically assigned to unique output path as-
signments in ascending order. For example, for
stereo output paths, output bus A 1–2 is as-
signed to output path A 1–2, A 3–4 to A 3–4, A
5–6 to A 5–6, and so on.
