Muse Kinetics is a Berkeley, California-based music technology company that designs expressive MIDI controllers and hardware/software tools for musicians and producers. The company is the rebranded continuation of Keith McMillen Instruments, founded by inventor Keith McMillen, and carries forward his legacy of building gestural, touch-sensitive instruments for performance and production.

The company is best known for compact, road-ready MIDI controllers built around a proprietary smart-fabric sensor technology — a felted material infused with conductive particles that registers nuanced changes in pressure, position, and motion. Its product line includes the QuNexus and QuNexus Galaxy keyboard controller and MPE sequencer, the BopPad and BopPad Galaxy quad-zone drum pad, the SoftStep3 foot controller, the 12 Step2 foot keyboard, the K-Board and K-Board Pro 4 keyboards, and the malletSTATION mallet controller. Earlier products such as the QuNeo pad controller and the K-Mix mixer/audio interface have been discontinued but remain in wide use.

Muse Kinetics products are popular with electronic musicians, live looping artists, modular synth users, and producers who want compact, expressive control surfaces that travel well and integrate with computer-based rigs and CV/gate gear.

Muse Kinetics has 5 products cataloged on Equipboard, including MIDI Foot Controllers, MIDI Keyboard Controllers, and Electronic Pads.
