Not just a ‘theremin’ — that totally downplays the power of midi. Someone else mentioned the mimu gloves, and I love the idea of a vision based controller - almost everyone has a phone, tablet or laptop with a camera, especially if theyre making music.

I also love that this could blur the lines of music playing and dance.

Great job OP, thanks for sharing.

This instruments timbre and tone are literally dream shit to me, so wavy and I dont know—unearthly/worldly

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.

Seems like the same software could be used as a soundtrack for Tai Chi exercises. Would be pretty neat.

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.

Apple devices can do MIDI over Bluetooth. I've used this in the past to send VisionPro hand tracking data as MIDI.

I do this with "Apple Lightning to USB Camera Adapter". iPad basically talks to the midi sequencer via USB.
