Really cool you got to the point of using Leap Motion for music making. Nevertheless, to let you know, it wasn't the first time it was used in such way. For quite some years people have been doing it. There are several external objects for Max/MSP, people that used it with Unity or Python, and at some point there was even GECO, a software to convert the Leap Motion data into MIDI/OSC messages, which nowadays is not supported anymore.
I'm a musician working with Live Electronics as well, and for around 2 years have been playing with Leap Motion and researching what ways/gestures would be meaningful, from a composition and performative point of view, to have for other musicians to use. I'm based in the Netherlands, and did this research at the Conservatory of Amsterdam. At the moment I'm on my way to develop a software that converts directly the Leap Motion data to MIDI and OSC but also includes gestures recognition, thus including conclusions of the aforementioned research.
If you would like to know more about the state of the project, would like to become beta tester or collaborate in some way please feel free to contact me via:
Have a nice day,
