Had a quick look at the website. Sounds interesting
The biggest problem I find is that there are so many different ways/devices that will all do basically the same thing - with varying degrees of difficulty/effect/cost etc.
Every manufacturer will claim that there's is the latest and greatest and so you have to go through a process of extensive research to try and ascertain whether the thing works - is practical - and VERY important - what limitations does it have??? They never tell you that
The one you are looking at looks like its been designed to do everything you want and is much more practical than some of the other devices I am aware of that are much more suited to a studio environment.
It will be interesting to see what/if feedback you get to your question. Have you raised it in other performer-related forums/newsgroups? How did you come upon this one? Any chance you could try it out somewhere??
