The RS-202 is a fully polyphonic analog string synthesizer released by Roland in 1976. The keyboard is permanently split into two separate sections, the lower 2 octaves and the upper 3 octaves, and each section has it's own set of identical controls. These include three white On/Off buttons for each of the three sound presets. This means you can assign any sound to each section, in any combination. Features sound presets Strings I, Strings II and Brass, and two Ensemble (Chorus/Vibrato) modes. Made in Japan.
