stereo input by default, but you can
always unlink them in SETTINGS >

As the audio is directly generated in
digital, there is no need for PRE or
DYNAMICS.
When you have a stereo track, the
typical use is in stereo (linked)

If you have a mono backing track on
one channel, and the metronome
click on the other, then you may
work in dual mono mode, which
allows you independent pan and
mixing controls.
