There is currently no way to send a full rig with cab out the Mains and a full rig no cab to Amp Outputs. The guys at Avid mentioned that there is no way to do so because it would use more DSP. If the Amp and Cab blocks were separate, the user could put the cab at the end of the chain, and select between full rig pre-cab or full rig for either output. No extra DSP needed!
