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

On the Hungarian "tekerő" the same control is achieved by using a wedge called the "recsegőék" (control wedge, or literally "buzzer wedge") that pushes the drone string downward. In traditional "tekerő" playing, the buzzing bridge is controlled entirely by the wrist of the player and has a very different sound and rhythmic possibilities from those available on French instruments. Regional types of hurdy-gurdies since the Renaissance can also be classified based on wheel size and the presence or absence (and type) of a buzzing bridge. The following description of various
