Vortex Sound Research

https://www.tapwithus.com/ I just saw an ad for this, seems interesting but might be one of those bits of tech that is cool for a few mins then gets tedious. However, I've seen some interesting stuff with synths in VR, so this led me to imagine controlling iPad soft synths with Tap. Does it work? Anyone doing it? Specifically, it would be pretty neat if you could play the keyboard on a hardware synth and have all of your hand movement also control a soft synth. You know, like MIDI...but more futuristic...or something.
