Back in 1980, this Japanese-made gem emerged as a dedicated analog organ synth, stripping away the strings from its sibling the RS-09 to zero in on pure, mixable organ tones with a fully polyphonic twist.
At its heart sits a single analog master oscillator (S10430) paired with an octave divide-down chip (AY-3-214), letting you blend square waves across 8', 4', 2', and 1' drawbar-style sliders for that vintage organ stack. A simple lowpass filter with emphasis tweak, two attack modes (organ-fast or piano-with-decay), variable sustain, and an accent button add expressive control, while built-in vibrato LFO and MN3009 BBD analog chorus give it lush depth. The 44-key non-velocity-sensitive board sits in a compact black chassis (676 x 306 x 102 mm, 6kg) with stereo outs (level-switchable), headphone jack, gate out, and sustain pedal input—plug-and-play for hands-on tweaking without menus or memory.
Over the years, players dig its raw, limited-but-charming organ vibes for retro layers and textures, though some note the tones stay firmly in "vintage novelty" territory rather than versatile leads. A quirky classic for anyone chasing early Roland warmth.
