Correct path is 'Options-prefences-audio tab-drivers button'.

Enable the outputs you need by highliting them. The one that is highlited and closest to the top will be the default or output 1&2. The next one down that is highlited will be audio port 2, next one is audio port 3, etc.


Then regular (unassigned) audio tracks will go to the default (1&2) outputs.
Right-click under the track name and select the other output port for the track you desire to send separate (probably port 2 since it should be the next one down that is highlited).

It has to be enabled in the options area, then chosen for the track port.


I do not work here, but the benefits are still awesome
