Perhaps one needs to go a level up: if making the program is now semi-trivial, it remains to be proven if using the program to actually perform is. If I have a Star Trek replicator that can reproduce a perfect Stradivarius for me, is it any less impressive when I play a beautiful song on it?

If we want to get excited about a mixing board... we probably need to see someone using it in ways that traditional mixers don't facilitate.
