Curve your hands into a C.

Turn them a little toward the camera. Strings of light stretch between your fingertips.

Always in key. The note pops at your fingertip.

Coming in 2.1: FoxBox for Ableton Live.

Play any synth with your hands. FoxBox sends MIDI (plucks are notes, your hands move knobs) to a FoxBox device in Ableton Live that you install from the app in one click, or to any DAW through the FoxBox MIDI port. Ableton Link keeps the tempo in sync, and every take can save a .mid.
