Oh, come on, man. Dawg boy? Really?
I meant Amplitube, Guitar Rig, Wall of sound, Recabinet. The concept of software that emulates different mics on the same speaker cab is not new. They vary in quality and in the implementation methods, but it's still software that can represent non-linearities only to a certain extent.
Realistically, I think most project studio owners and home recording enthusiasts (including me), whom I believe VMS is marketed at, won't tell impulse from the real cab and mic in a blind test, let aside Kemper profile from the profiled setup. So this does not even need to be anything incredible technology-wise to sell well.
I respect Slate Digital a lot, their products are indeed great and I would love to work in that team of DSP developers, AND it's a great product, but the announcement was a bit overdramatic IMO.
