Theremin.

Here's someone playing a theremin who's reasonably good.[1]

From the article: "When using AirBending for pitch control, you can lock your gestures to specific musical scales and keys. This ensures every note you play is perfectly in tune with your composition"

Reminds me of the Moog Theremini - that was a fun bit of kit.

Great work but wouldn't the iPhone with the lidar depth sensor be a better device?

It’s on the plan to expand this app for iPhone. But, I haven’t tried lidar, so I decided to release for macOS first.

Also with iPhone, I have to think how to transmit MIDI data to DAW on laptop. Well, most likely via USB or network.

This is really cool, thanks for sharing.
