I'm actually plugged into an Eleven Rack with one AMP OUT to a Mesa Mark V and the other AMP OUT to an ADA MP-1.
The Mark V is connected to the LIVE. LIVE S/PDIF output goes into the 11R and LINE OUT goes into a Mackie 1640FW channel panned full right.
The MP-1 goes to the CAB which is fed into another 1640FW channel panned full left.
1640FW stereo out goes into 11R LINE INPUT L & R.
This routing provides:
Guitar DI from 11R
11R Rig Left
11R Rig Right
L S/PDIF : Processed LIVE
R S/PDIF : Unprocessed/Direct LIVE with WoSIII plug-in for cab sim's
L 11R LINE INPUT : MP-1 & CAB
R 11R LINE INPUT : MkV & LIVE
True virtual wall of sound. Really crazy to think about and the possibilities are numbing.
