The free Rippler download disappeared on 20 July 2026, when its developer archived the GitHub repository and pointed everyone towards reFX instead.
That beta had been circulating since February, a 32-voice physical modelling instrument with twelve resonator models and a three-month expiry quietly baked into it. Producers grabbed it and built whole kits with it. Then the page went dark.
The repository is read-only now. A short note from the developer says the synth has been published with reFX, and that building a commercial project had been the goal from the start. No binaries, no installer, nothing left to mirror.
If you missed the February window, there is no legitimate route back to that build. Copies drifting around forums are unsupported and time-limited anyway, because the beta was written to stop working after three months. Chasing one is wasted effort.
The reFX release is not a straight repackage either. It adds wavefolding oscillators and a full multimode filter stage on top of the twin-exciter, twin-resonator core, which changes how hard the instrument can push before you reach for an effect.
You get nine resonator models, up to 64 partials each, and two resonators you can couple in serial or parallel. Noise and mallet exciters drive them. Microtuning runs through MTS-ESP, and since version 1.4.0 you can feed external audio straight into the resonator section.
The sound-shaping controls are blunt in the best way. Inharmonicity, tone, material and decay do most of the work; the noise exciter has its own multimode filter and envelope, and the mallet has a stiffness control that takes you from soft felt to hard plastic in one sweep.
Builds cover Windows, Linux and macOS in VST3, LV2 and AU formats. The macOS builds are unsigned, so Gatekeeper will fight you on first launch. Linux users have no alternative here, because reFX ships macOS and Windows only.
Those extras are substantial. There are 441 factory presets, 32 exciter samples, twelve effects per layer plus a master chain, 64 LFO shapes and an arpeggiator with its own presets. Bell, djembe, vibraphone and a manual partial mode join the model list.
The three more models sound minor on paper. In practice, it decides whether you are sculpting a djembe from a membrane approximation or simply loading one, and that difference eats hours over the course of an album.
Microtuning accepts Scala files as well as an MTS client, and MPE and aftertouch are handled properly. Load a djembe patch into the polished twin-resonator Rippler reFX now sells, then drop the same idea into the older free build, and the gap reads as finish rather than physics.
Installation runs through the reFX Cloud App with online activation, which rules it out if you keep studio machines off the network. You need 8GB of RAM as a floor, 16GB for comfort, and either macOS 10.13 or newer or Windows 10 and 11. The install itself is tiny, roughly 51MB, because modelled instruments carry no sample library to unpack.

The archived GitHub repo took the free beta with it
reFX confirmed the synth publicly on 18 July, and the repo went read-only two days later. The sequence tells you this was a signed deal rather than a takedown, and the developer has said as much in plain terms.If you missed the February window, there is no legitimate route back to that build.

RipplerX is still free, still open, still getting updates
RipplerX, the older and smaller project, never moved. It remains a free physical modelling synth you can still download today, sitting under a GPL 3.0 licence with version 1.5.19 dated 13 June 2026. That is a long way past the point where most free plugins go quiet.You get nine resonator models, up to 64 partials each, and two resonators you can couple in serial or parallel.

The $99 intro price buys effects, presets and polish
reFX put Rippler on sale on 30 July 2026 at $99, rising to $129 after 13 September. A 30-day trial sits behind a free account, which is the honest way to work out whether the extras earn their keep in your projects.Those extras are substantial.
