The Leap Motion Controller came out in 2014 already (11 years ago, wow!) and isn't very expensive. The SDK was lacking in the beginning if I recall correctly, but a webcam seems to be inferior. Technology isn't the limiting factor for a quite some time now. I'm sure many projects existed to translate gestures to MIDI, some less polished, some more polished[0][1].

Reminds me... I even used two PlayStation Eyes (EUR 5 each) with OpenCV and the EVM algorithm[2] on a ThinkPad X230 for a dance performance piece back in 2015. Movements rather than gestures and OSC instead of MIDI, but it worked great!

Open the app and open Logic Pro. Create a MIDI track on Logic, try waving to the app it should automatically receive MIDI message from all channels and all MIDI devices.

Then if you want to filter the track to receive specific MIDI channel from specific device, for example AirBending channel 2, then find it in the dropdown in the MIDI inspector section in the same MIDI track.

It seems possible, since Apple’s Vision framework can read body pose too. Maybe I can try it for the next update.

This is not an instrument and does not have a timbre. He is used a midi instrument in a DAW and using this software as a midi controller.

This is not a theremin, it’s a programmable controller which you can tie to various midi inputs. Think “slider” or “dial”.

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.

Since I developed it using Vision framework from Apple, the current focus is still for Apple devices. So, not in the near future to develop for Linux and Windows.
