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.

This one’s a two-in-one. Check the Tuning panel!!

Man oh man, am I a sucker for a string machine. But this one is really great. Open up the tuning panel above the keyboard, and see that there are controls to micro tune each note to sound a little bit off key, like always happens organically on the hardware versions. I like to modify the presets by turning off the String side, or the Organ side. Don’t forget to boop open the FX panel in your wanderings. You thought you might be able to live without a spring reverb. Turns out now you don't have to.

Play abit on its keyboard and the notes repeat back as though you are recording and playing back. Tone doesn’t quite have that rich late 70’s / early 80’s ensemble sound but was hopeful as their other apps are decent.

Developer Response
If you have a bug to report, please reach out to us directly through our website.The ensemble sound is an exact match to the original unit, as we carefully modeled every component of the circuit. It's quite different from something like the JUNO chorus, this character is unique to the synth we emulated. You might find it unusual or not to your taste, but that’s the sound of the hardware.
