TouchKeys transforms the piano-style keyboard into an expressive multi-touch control surface. Sensors on the keys measure where you place your fingers, letting you control vibrato, pitch bends and other techniques naturally and intuitively. The sensor kit installs on any full-size keyboard, retaining the familiar keyboard action while expanding its creative possibilities. TouchKeys can control any synth via MIDI or OSC. It is available as a DIY kit or as a build-to-order instrument on Novation Impulse and Doepfer LMK2+ keyboards.
