Keith McMillen Instruments shared this short demo of gestural mixing, using their K-Mix programmable mixer, a Leap Motion controller and Web MIDI.

Whether or not you’re interested in gestural mixing, the video demonstrates how the K-MIx’s extensive MIDI support lets it be controlled just about any way that you want. 

In the video, the channels are mapped to hand gestures like this:

• Left hand (fingers, excluding thumb): faders 1-4
• Right hand (fingers, excluding thumb): faders 5-8
• Fist: Master fader

Fader level is controlled in the vertical axis (moving your finger up/down), and stereo panning is controlled in the horizontal axis (moving your finger left/right).

Technical details are available at the KMI site.
