Eigenlabs: Eigenharp

The Eigenharp brings truly expressive musical performance to every musician. The 3D keys are amazingly sensitive - sensing pressure for volume, side to side for effects and moving up down for pitch. Each Eigenharp comes with a breath pipe and one or more strip controllers used to control any aspect of a sound - such as triggering notes and applying effects and filters. You can also attach pedals, headphones and a microphone. You can change the key layouts, instrument mappings, scales, how all the controls behave - just about everything in fact.

Inspired Instruments: "You Rock Guitar"

The You Rock Guitar is both a digital (MIDI) guitar (with 6 strings and a touch-sensitive digital fret board) AND a game controller (adapters available for Xbox, PS2, and Wii). And it has a built in synthesizer with a "You Rock" mode for learning to play in the right scale with only the right notes.

The Misa Digital Guitar is a guitar without strings. It is a MIDI controller that you play using a touch screen along with switches on the fret board. With the touch screen you can adjust four synth parameters simultaneously. It is not meant to replace a stringed guitar, but for playing electronic music.

The GypsyMIDI is a unique performance instrument for motion-capture MIDI control... The suit is modeled on the human skeletal form using rotational sensors placed on the joints. The GypsyMIDI simply plugs into a MIDI interface and arm movements are converted into a real-time stream of MIDI data. The mapping interface eXo-software allows the user to define how the movements are translated into MIDI control, including the ability to trigger notes, generate continuous control commands or even play scales.
