What it does

  • Touchless theremin

    One hand for pitch, one for volume. Play in the air with nothing to hold and nothing to touch.

  • Scales and scale snap

    Choose a key and scale; snap keeps every gesture in tune, from smooth slides to dramatic sweeps.

  • Natural vibrato

    Raise your hand for a deeper vibrato, or wobble around the note the way you would on a real theremin.

  • Near-zero latency

    Motion prediction tracks your hands so the sound follows the instant you move.

  • MIDI/MPE out

    Use Wavebender as a virtual MIDI/MPE instrument and play your synths and your studio.

  • Private by design

    Camera frames stay on your device. Only your sound presets and calibration are saved, locally.
