Hurdy-gurdy strings are purely generated electronically by the keys and also in combination with the rotation of the wheel. The signals for drone strings and the snares are generated by the crank movements of the wheel. The data exchange of the musical information between the hurdy-gurdy and connected computers, samplers or synthesizers are managed via MIDI interface. Hurdy-gurdy The hurdy-gurdy is a stringed instrument that produces sound by a hand crank-turned, rosined wheel rubbing against the strings. The wheel functions much like a violin bow, and single notes played on the instrument sound similar to those of a violin. Melodies are
Hurdy-gurdy bridge for additional drone strings on some instruments). The free end of the dog (called the "hammer") rests on the soundboard of the hurdy-gurdy and is more or less free to vibrate. When the wheel is turned regularly and not too fast the pressure on the string (called the "trompette" on French instruments) holds the bridge in place, sounding a drone. When the crank is struck, the hammer lifts up suddenly and vibrates against the soundboard, producing a characteristic rhythmic buzz that is used as an articulation or to provide percussive effect, especially in dance pieces. On French-style instruments, the
