Sleight is a free, open-source macOS app that tracks hand movements and turns them into MIDI performance controls.

Landing page captured for the 2026-08-29 issue.

Field notes

The app maps distinct gestures to musical parameters: horizontal hand movement produces continuous pitch changes, pinch controls note and volume behavior, and finger curl triggers floating pads. Its output appears as a standard CoreMIDI source, with selectable MIDI 2.0, MPE, or MIDI 1.1 modes. The page also documents automatic synth muting when a DAW is connected, allowing Logic or Ableton to receive the signal without doubling the sound.
