Though monophonic, the Ondioline is capable of creating a wide variety of sounds. Its keyboard spans three octaves, but by adjusting a register knob a player can render up to eight octaves. The instrument's keyboard is suspended on custom-designed springs, which enables a natural vibrato if the player manipulates a key laterally (from side to side) as that key is depressed. The keyboard is pressure-sensitive, and volume is controlled by a knee lever.
