reFX Rippler – Physical Modeling Synthesizer

Most synthesizers start with an oscillator and filter it into shape. reFX rippler starts somewhere else entirely: with physical modeling. Its modal synthesis engine excites banks of resonators based on twelve acoustic models, from strings and bells to membranes, plates and tubes, generating sound with no samples at all. Combined with classic subtractive oscillators and filters, it is a hybrid instrument for sounds that feel alive.

Resonators instead of oscillators

The core idea of reFX rippler is simple to grasp and deep to explore. Rather than playing back a waveform, you excite a modeled physical structure and let it ring. A string model plucks, a membrane model thumps, a tube model resonates, and because the models are generated mathematically, you can push them far beyond their acoustic origins into metallic, percussive and experimental territory. Bi-directional energy coupling between resonators adds evolving behavior that static samples cannot match.

Two independent layers multiply the possibilities. Run them in parallel for stacked complexity or in series for interactive resonance, with each layer adding two oscillators and two filters from a selection of 27 types. An exciter section with samples, custom impulses, sample import and even live sidechain input means you are never limited to the built-in models.

Key features of reFX Rippler

• Physical modeling synthesis with twelve acoustic models

• Modular effects: 13 master FX plus 12 per layer
• 441 factory presets plus arpeggiator and sequencer
• Scala and MTS microtuning support

Modulation, expression and tuning

reFX rippler is built for players and tweakers alike. Four LFOs, four envelopes, random generators and macro controls with custom response curves feed a drag-and-drop modulation system, while MPE and aftertouch support make it sing on expressive controllers. For the adventurous, Scala and MTS microtuning open up scales beyond twelve-tone equal temperament, and Manual mode lets you paint your own additive resonator configurations from scratch.

The modular effects section treats processing as part of sound design: reorder the chains and the same patch becomes a different instrument. With the five-mode RutaVerb and a lighter MiniVerb among thirteen effects, reFX rippler can be a complete production environment for a sound, not just a synth voice.

Who is reFX rippler for?

Sound designers and experimental electronic producers will find the most to love here: plucks that behave like real objects, evolving cinematic textures, metallic percussion and organic pads. Film and game composers get an expressive acoustic-electronic hybrid. If you want bread-and-butter analog emulations or EDM presets, a conventional subtractive synth serves you better; reFX rippler rewards curiosity.

It installs via the reFX Cloud app at roughly 51 MB, runs VST3, AU and AAX on macOS 10.13 or later with native Apple Silicon support, and VST3 or AAX on Windows 10 or 11. It needs 8 GB of RAM minimum and an internet connection for activation. Check the product page for the latest details.

Frequently asked questions

Is Rippler a sample-based synth?

No. Its core sound comes from modeled resonators rather than conventional sample playback, though the exciter section can use samples and live audio input.

How many presets are included?

441 factory sound presets, plus arpeggiator presets, LFO shapes and online documentation.

Does it support MPE and microtuning?

Yes. It supports MPE and aftertouch for expressive performance, plus Scala tuning files and MTS for alternative tuning systems.

Distinctive synthesizers are worth more than their price when they change how you write. At Plugboutique’s deal pricing, reFX rippler is an affordable door into physical modeling synthesis.
