RES-09

About

The RES-09 is a faithful emulation of a classic analog organ and strings machine from the late 1970s, the Roland RS-09. Though not as widely known as some classic vintage synths, it remains a sought-after gem for its lush ensemble effect, rich divide-down organ tones, and warm analog strings. Our recreation captures the original character while offering modern enhancements, making it an essential tool for vintage-inspired sound design.

You can fine-tune each oscillator separately and shape your sound even further with four effects that you can mix and match to your liking.

The Roland RS-09 was an analog organ and strings synthesizer, closely related to the Saturn-09, which was limited to organ sounds. Released in the late 1970s, it uses a classic Top Octave Generator with 12 oscillators for the highest octave, while octave divider circuits generate the lower notes, enabling full polyphony across both sections. The Mark I model was launched at the end of 1978 and was refreshed as a Mark II model in May 1980.
