Roland RS-09 Organ/Strings (1978)

Name: Roland RS-09
Brand: Roland

Roland's budget string machine - a 44-key organ and strings combo that gave up paraphonic tricks for portability and a price working bands could afford.

Overview

The RS-09 is what you get when Roland looks at its RS-202 and RS-505 Paraphonic and asks what can be stripped away. Released in 1978, it sits at the budget end of the company's string machine lineup, below the earlier RS-202 and well below the flagship RS-505. Those models offered more voice options and paraphonic capabilities. The RS-09 reduces everything to two basic sections with minimal controls: organ and strings.

The instrument is a dual-voice keyboard built around divide-down top-octave synthesis. The keyboard has 44 keys, runs F to C, and is non-velocity-sensitive throughout. Polyphony is full - every key sounds at once, a natural result of the divide-down design. The organ section has a simpler tonewheel-style voice. The string section uses a chorus ensemble effect to thicken the divide-down oscillators into the pad sound the genre is known for. Both sections have independent volume controls and can be layered, and a single tone control sets overall brightness.

The RS-09 doesn't go out of tune. The divide-down design keeps pitch locked to the top-octave oscillator, so there's no drifting oscillator bank to warm up and no tuning ritual before a set. The trade-off is that all notes share the same tonal character with no voice-to-voice variation. The chorus circuit is the sole source of movement in the sound. Players who want surprises will be disappointed. Players who want a reliable organ-and-strings texture that sits in a mix will get it.

The footprint is modest: approximately 860 × 100 × 280 mm, which makes it properly portable. Sellers have shipped these at around 20 kg packed, which says something about how much of that is instrument and how much is packaging. The RS-09 was designed to be carried.

Key Features

44-Key Keyboard (F to C)

At 44 keys, the keyboard is shorter than a standard 49-key layout, which can catch players used to a full four-octave span. The F-to-C range keeps the chassis compact and the price down. Keys are non-velocity-sensitive, which fits the divide-down design: there's no per-note dynamics to respond to. Organists and string machine players of the era were used to this. Anyone coming from a weighted or touch-sensitive instrument will need a few minutes to adjust.

Divide-Down Top-Octave Synthesis

Sound generation is divide-down top-octave synthesis, the same basic approach used across the string machine category. A master oscillator generates the top octave, and frequency dividers produce the lower octaves from it. That is why the RS-09 stays in tune regardless of temperature or warm-up time, and why every note shares the same tonal character. There are no per-voice filters, no individual oscillator tuning and no drift.

Chorus Ensemble (Strings Section)

The string section's character comes entirely from its built-in chorus ensemble effect, which thickens the divide-down oscillators into the shimmering pad of the string machine sound. The chorus is the sole source of movement. There's no LFO modulating pitch or filter, and no envelope shaping the strings beyond what the chorus provides. A French classified listing describes the instrument as having "le chorus Roland si caractéristique" - the characteristic Roland chorus. The RS-09's strings are thinner and more nasal than the Solina String Ensemble, but they sit well in a mix, particularly when layered with other instruments. Units with aging chorus components can develop an uneven warble that some players actually prefer.

Organ Section

The organ section offers a simpler tonewheel-style voice. It isn't a tonewheel emulation in any technical sense, just a straightforward organ timbre that sits alongside the strings without competing for the same frequency space. It's the combo organ half of the "Organ/Strings" name, and it works alone or layered with the strings. There are no drawbars or waveform selectors. The organ voice is fixed, and its independent volume is the only control over it.

Independent Volume Controls and Layering

Both sections have independent volume controls and can be layered, which is the RS-09's main performance flexibility. A player can run organ alone, strings alone, or both, balancing them by ear. A single tone control sets overall brightness. It's a global filter, not a per-section control, so it affects both voices at once. Beyond that, the sounds are fixed, with no waveform selectors or filter controls other than the tone knob.

Gate Out Port

The RS-09 has a Gate Out port. Owners report that despite its limitations, the RS-09 will do exciting things when its Gate Out is connected to external gear. Moog Forum users specifically note patching it to Moogerfoogers. It's an easy feature to overlook on a budget instrument, and it lets the RS-09 work as a controller or trigger source in a larger setup.

Tuning Potentiometer and Serviceability

A tuning potentiometer is accessible on the instrument, and replacement parts are documented: a 100KB rotary potentiometer for the TUNING function, and an ALPS pushbutton power switch rated 5A-250V as the original part. Third-party AC adapters are available at 9 V output with a 4-foot cable, useful for anyone buying a unit without its original power supply. Specific service parts are still documented and available.

Historical Context

Roland released the RS-09 in 1978, at the budget end of a string machine lineup that already included the RS-202 and the flagship RS-505 Paraphonic. Those models offered more voice options and paraphonic capabilities. The RS-09 stripped things down to two basic sections with minimal controls, organ and strings, making it one of the most straightforward string machines Roland ever produced. It was Roland's answer to musicians' need for a budget-friendly, portable string machine that also had combo organ tones, and these were found on many stages in the early '80s.

The RS-09 found a niche in new wave, post-punk, and early electronic music. Its compact size and low price made it accessible to bands who couldn't afford a Solina or RS-505, and it delivered the essential string machine texture without the cost or complexity of the higher-end models. A MKII variant exists - a French classified listing references a "Roland RS 09 mkII" - though the differences between the two versions aren't clearly documented. The instrument is referenced alongside the Yamaha SK20 and Moog Opus-3 as a comparable model in the same general category of budget organ/string combos.

Collectibility & Value

eBay completed sales from October 2026 show a range of $466 to $670, with a median of $570 across five completed sales in the past twelve months. Volume runs about one unit per month, so finding a specific condition or price takes patience. Recent listing prices have ranged from $450 for a used unit to $701 for one described as in good condition, with $489 and $662 falling in between. One data point from February 2026 shows a sale at $603.

Japanese sellers have listed the RS-09 at a regular price of $686.11 with a sale price of $526.59, and at least one listing notes that the instrument was tested and confirmed to output sound from all keys. A French listing describes a unit that was "complètement révisé" - completely serviced - three months before sale, which is a good maintenance history to look for. The most common condition issue noted is the aging chorus circuit, which can develop an uneven warble that some players actually prefer. It's worth checking before purchase.

Parts availability is better than average for a budget instrument of this era: the tuning potentiometer and power switch are both documented and available from parts suppliers, and an owner's manual exists. Original bags and stands occasionally turn up with used units, and at least one listing included a hardcase.
