Roland RS-505 Paraphonic

Released in 1978

The RS-505 Paraphonic is a 49-note string machine with a split keyboard, enabling bass on the lower keys and strings and/or poly-synth on the upper and lower. A four-stage BBD ensemble effect really thickens and animates the sound. The RS-505 can even process incoming audio through the BBD effect!
