Yea, you would just send the instrument/synth to a certain outputs separate from the main mix, feed that output into your compressor/effects unit, then take the return of the unit and feed into one of your inputs...

So, everything is running thorugh the Fireface. Is it possible to set up an external preamp/compressor through the fireface where any virtual instruments I use in sonar, (Drums from sfz for example,) could run through the external compressor, or are external compressors limited to hardware synths?
