across a five-octave keyboard. The signal was then fed through a single envelope shaper, making the instrument paraphonic. The front panel had two separate controls for the top and bottom of the keyboard, which could have independent sounds. Each note could be assigned a separate envelope articulation, which was necessary to avoid re-triggering the attack if an extra note was added to an existing chord being played. To achieve a more realistic sound of an ensemble of string players, the output was fed through a

using a number of delay lines triggered by low frequency oscillators. An American company called Multivox manufactured a clone of the RS-202, called the MX-202. It used similar internal components, though the sound was weaker. Notable users of the RS-202 include Genesis' Tony Banks, Camel's
