Roland RS-202 Strings

   (0 reviews)

The Roland RS-202 was a polyphonic string synthesizer, emulating the sound of string instruments, introduced by Roland in 1976. It was the successor to an earlier polyphonic string synthesizer, the Roland RS-101, released in 1975.

The synthesizer operates using sawtooth wave oscillators, which used a frequency divider in a similar manner to an electronic organ to provide full polyphony across a five-octave keyboard. The signal was then fed through an envelope shaper. 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 chorus effect using a number of delay lines triggered by low frequency oscillators.
