I am always looking for ways to add expression in the performance when I record. And I’ve seen some composers use the Leap Motion controller to great effect.
Do anyone of you have experience with this device for music, or any views/thoughts about it to share? 
Here’s the new Infinite Woodwinds 2.0, where Aaron performs beautifully with the Leap Motion controller:
Interesting. Like a theremin 
I have no idea how it works, but it looks so musical and expressive to use! 
The “dance” is similar to a theremin but the principles of working are different. And yes, could be great try those gadgets. Or create one. it would be a fun time. I’m industrial engeneer but not electronic specialist. Maybe i research a bit 
I ran into the developer of MidiPaw the other day; a more capable alternative to the seemingly abandoned GECO. Unfortunately, MidiPaw is (so far) Windows-only, but it uses v4 of the Leap software, which, unfortunately, is also Windows-only - but there are rumors about v5, OS X and whatnot…
