Hello, I'm currently using an RME fireface as my audio interface with sonar, and am not using any other external mixing board. 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? Thanks. Omar Binno Website: www.omarbinno.com AIM: LOD1116 Skype: obinno1
