Using the Leap Motion device to input 3D data, a MidiFighter Classic to provide button input, and Touch Designer to drive the visuals.
The top row of the MidiFighter records input when held down, and the buttons in the row just below play them back when held down. Everything is momentary for now.
I'm really digging the combo of the MidiFighter and the Leap - they have complementary strengths. Still have much work to do like smarter handling for the switch between live and recorded data, and enabling toggle vs momentary recordings.
