A controller 10 for a sound generator comprises: an elongate body 16 to be held by a musical performer with both hands; a plurality of tone keys 20, which may be capacitive touch sensitive keys, on the body for selecting musical notes to be played; and a gyroscopic MEMS sensor for sending to the sound generator a signal for setting a parameter of the generated note in dependence upon the sensed attitude of the body. Additional MEMS sensors for detecting acceleration and magnetic fields may also be included. The controller may also include a plurality of control buttons 17, disposed a distance away from the tone keys, and may include a scale selection button to permit the frequency of the generated notes to be varied. The control buttons may include a tracker ball or joystick. Light emitting diodes may be provided adjacent to each tone keys, which may glow with different intensities or colours. A shoulder strap may be provided. |
