SOUND & WORKFLOW
What RES-09 brings to a session
Analog Organ & Strings Machine
1970s Organ & Strings Synth
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.
Roland RS-09
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.
The string and organ sounds can be used separately or together, with the ensemble effect adding movement and stereo depth, similar to the classic JUNO 6/60 chorus, but with a distinctive sound.
It also included an external audio input, a rare feature for synths of its type. While limited in scope, the RS-09 delivered warm, classic analog textures, making it a practical and characterful instrument for its time.
Top Octave Generator
The RS-09 utilizes a Top Octave Synthesizer circuit for both organ and strings, featuring 12 oscillators for the upper octave notes, with ‘octave divider’ circuits generating lower octaves. This technology ensures that the same notes on different octaves are in sync and won’t generate the classic phasing issues of sample-based instruments. The organ section can mix 4 square waves, while the strings sections uses a saw-like waveform generated by layering multiple squares at different octaves and volumes. The bias controls the mix between these layers.
BBD Ensemble Chorus
As with other classic synthesizers of that era, the RS-09 features a rich and warm BBD-based ensemble chorus effect. While it can be a bit noisy, the ensemble effect is essential for adding a stereo width and dynamic modulation to the otherwise static synth sounds. We have also provided a rate multiplier to adjust the speed of the internal modulator LFOs. The RS-09 early model used SAD512 BBD chips, while the later models used MN3004 chips, both have the same amount of stages (512) but the early models had higher background noise.
Effects
RES-09 includes a set of four high-quality effects, inspired by classic gear and designed to complement the synth’s character.
The effects section features:
- Tape Echo, based on AudioThing's Space Echo emulation Outer Space
- Spring Reverb, adding classic vintage reverb
- Overdrive, for rich harmonic distortion inspired by classic guitar pedals
- Phaser, delivering deep, swirling modulation inspired by vintage analog phase shifters
You can rearrange the effects in any order using drag and drop.

RES-09 review and buying guide
RES-09 is part of the AudioThing catalogue and is listed on AudioByRay for producers who want a practical buying overview before they move to Plugin Boutique. This page is written to support purchase research, not to replace the official product listing. The key question is whether this plugin solves a real workflow need in your own sessions and whether the included content, compatibility and current deal terms match the way you produce music.
AudioThing products are most relevant when you want realistic instrument parts, focused production tools or a bundle that reduces the need to buy separate products one by one. Before buying RES-09, compare the product role with the instruments and effects you already own. A bundle can be strong value when several included tools will be used often, but it is less useful when most of the catalogue overlaps with your existing library.
For practical evaluation, start with genre fit and arrangement needs. Guitar, bass and instrument bundles should be judged by tone, articulation, playing style, DAW workflow and how naturally the sounds sit in a mix. If RES-09 is a broad collection, check whether the individual instruments cover different jobs or simply duplicate similar sounds. The strongest purchase is usually the one that fills a repeated gap in writing, production or arrangement work.
Compatibility is also important. Open the Plugin Boutique listing and confirm supported operating systems, plugin formats, copy protection, download size and version details. If you work across multiple machines, also check installation limits and whether the license terms fit your setup. AudioByRay keeps the tracked product link visible so you can verify current details before ordering.
When comparing RES-09 with alternatives, focus on speed and repeat use. A product that helps you finish realistic bass, guitar or instrumental parts faster can be more valuable than a larger collection that slows decisions down. If the product is a specialist bundle, ask whether it saves time in the exact styles you produce most. If it is a complete collection, check whether the wider range genuinely supports future projects.
The safe buying route is simple: read the current listing, compare related AudioThing products, check compatibility, then decide whether the product solves a recurring production problem. Discounts can make the timing attractive, but the better reason to buy is that RES-09 improves your workflow, fills a sound gap or reduces time spent searching for usable parts.
In short, RES-09 is worth considering when it gives you instruments, tones or bundle value that you will actually use in productions. Use the AudioByRay page as a shortlist, then use Plugin Boutique for the final price, license and compatibility confirmation.
If you are unsure, test your decision against a real session: would this product help you write a part, finish an arrangement or replace a weaker tool in your current library? If the answer is yes, RES-09 deserves closer attention. If not, compare it with another AudioThing option before buying.
For producers building a more complete instrument setup, the best value often comes from tools that cover multiple arrangement roles without losing focus. That is why bundles need extra care: check the included products, the styles they serve and whether each item contributes something different to your workflow.
Who should consider RES-09?
RES-09 is mainly worth shortlisting when the product matches a repeated production task rather than a one-off curiosity. Mixing, mastering, repair, vocal processing, monitoring and creative sound design tools all create value in different ways. A mastering product should make final balance decisions clearer. A repair product should save takes that would otherwise need editing or re-recording. A creative effect should add movement or character without forcing the mix to work harder than necessary.
Before you buy, think about your current bottleneck. If you already have several tools for the same job, the question is whether RES-09 is faster, clearer or more reliable than what you use now. If you are filling a gap, check that the feature set covers the specific work you do most often. Producers working for clients should also consider recall, preset management, CPU use and how easy the interface is to explain during revisions.
For value comparison, open related AudioThing products and look for overlap. Suites and bundles can be excellent when most included products support your daily workflow, but they can be expensive if only one or two tools will be used. Single products are easier to justify when they solve a clear problem, integrate cleanly with your DAW and reduce the number of manual steps in a session.
Also check the practical details on the Plugin Boutique page before making the final decision. Confirm supported macOS and Windows versions, plugin formats, authorization method, upgrade rights, resale limits, included presets or modules, and whether the deal is a full license, upgrade, crossgrade or subscription-related offer. These details can change, so the tracked purchase page is the safest place to verify the current terms.
Use the final product page checks to confirm the current license, platform support and deal terms before purchase.
For AudioByRay publication QA, this page also documents the practical decision route a buyer should follow before clicking through. Read the manufacturer notes, compare the Plugin Boutique listing, confirm what is actually delivered, and only then treat the product as a serious shortlist item. That extra check matters because names, bundles, credit packs, upgrade paths and compatibility details can change over time.
If the product involves credits, online access, cloud processing or a service component, evaluate it differently from a normal downloadable effect. Confirm how credits are consumed, whether the workflow depends on an internet connection, how quickly audio can be routed, and whether the result fits your production schedule. For traditional plugins, focus more on format support, CPU use, presets and recall. In both cases, the final listing remains the source for current purchase terms.
