Synergy Amps and Kemper

Hello all. I was watching the new video with Steve Vai demonstrating the synergy modules and he had 4 different amps going as he was saying he ABd to channels to get the 4 going. he had a deluxe , a bassman, twin reverb and a AC30 . so I checked out the synergy website and they have many amps. Diezel, Engl, Mesa Boogie, Marshall you name it. it would be interesting to see someone profiling 4 amps together both for clean and high gain. cheers.
