As with the trautonium, the instrument is played using the bandmanuals. A high-frequency master oscillator is used to produce subharmonics by means of frequency dividers. These subharmonics are combined to create a mixture (the term used for a specific type of organ stop) by means of a selection switch. This generates an idiosyncratic synthetic sound that is completely unlike that of any other known electronic instrument.
