Hello Tony-
The last word I heard straight from Peavey is that the GUI will not ever work. The company that they bought their processors from promised way more than they could deliver, and there simply isn't enough horsepower to pull everything off that they had hoped. They have some R&D going on, and some possible AA products that may make it to the Peavey side, but for now, no GUI controlled processors. I was bummed when I first heard this news as well.
I've used the autograph feature, but then I do my best to replace the resultant graphic eq w/ parametric eq's, and test it with my ears. You'll want your mic to be around 6-10 feet from the speaker. The cool thing about Autograph is that it makes adjustments, and then listens to see if those adjustments actually changed anything. If there is no change, it takes the unnecessary adjustment away. This is info straight from Marty at Peavey.
Going to Smaart training next week, so I plan on upgrading my tools and methods.
The VSX 48 does not have graphic eq or Autograph, but rather 6 parametrics on each of the inputs.
Thanks,
Grant
