and whoever did the ergonomics.. yay.. neck ache...
As someone who battles tendonitis, that's the first thing that crossed my mind.
I certainly wouldn't want to work 8-12 hours a day... holding my arms up in the air (to make adjustments).
That's an ergonomic nightmare. If you didn't already have RSI (tendonitis, carpal-tunnel), you'd develop it.
It's basically a virtual control surface... with built in monitoring
Unique approach... but far too cost prohibitive for the average DAW user.
Personally, I'd rather have tactile controls (faders/knobs) when trying to make fine adjustments.
