Here are a number of things to seriously consider:
-The 7600 audio quality has nothing comparable to it. The sound is just……
-the future s multicore DSPs. No need for 8. A couple of tri_core chips have tons of power.
-An H8000 can already do what you describe. You can have two full independent rigs (MVRacks) at the same time, using two stereo amps setups. Easily.
-7.1 isn't really much used. Good 5.1 is what is requested.
-Having MIDI Virtual Racks means no MIDI latency, particularly on the H8000, as one could use the 2 DSPs switching audio from one to the other, while changing preset in the abandoned one. DSP power has nothing to do with presets changing times, anyway.
-Computers have a lot of power these days. Unfortunately the way OSs and audio platforms are designed limit that power a lot. DSPs can still do much more…and sound much better.
all the best
