If this is to ever happen that would be the ultimate solution for recording but they must link the KPA as a large dongle to insure that it isn't cracked. I would love for that to happen, but I just can't even imagine them taking this large gamble, Fractal was supposed to release a software version of their early AXE FX but never did.
Having a dongle like the KPA would force hacking as it would make it inconvenient to use. I would like a KPA-VST so I can leave my Kemper in the truck for the endless gigging I do. An iLock would be ok but other VST makers get by like Toontrack and iZotope.
