Main outputs are a mix of a program’s A and B layers. When plugs
are inserted into the B outputs, only layer A is available from the Main
outputs and layer B is routed to the B outputs. See Layers, Split, and
Stack on page 43
for more information. The Prophet 12 sounds great
in stereo, but can be switched to mono. See “Mono/Stereo” in Global
Settings on page 9.
