RipplerX
Key Features
- Physical modeling synth engine aimed at resonant plucks, mallets, plates, membranes, tubes, and metallic percussion tones
- Dual resonators with serial and parallel coupling for layered or energy-transfer-style modal sounds
- Nine acoustic resonator models: String, Beam, Squared, Membrane, Drumhead, Plate, Marimba, Open tube, and Closed tube
- Inharmonicity, Tone, Ratio, and Material controls for shaping the resonator color beyond basic decay editing
- Noise and mallet exciters with velocity mapping for expressive struck and blown-style responses
- Up to 64 partials per resonator for detailed modal timbres without relying on sample libraries
- Open-source JUCE plugin with current Windows, macOS, and Linux release ZIPs on GitHub
Description
RipplerX by Tilr is an open-source physical modeling synthesizer built around resonators rather than sampled instruments or subtractive oscillators. It is designed for Chromaphone-style plucks, mallets, tubes, plates, membranes, bell-like textures, and other modal tones inside a compact cross-platform plugin.
The core workflow is deliberately focused: a noise source and mallet exciter feed dual resonators that can run in serial or parallel. Nine resonator models, inharmonicity, tone, ratio, material, and up to 64 partials per resonator give it enough control for metallic percussion, woody hits, tuned drums, bright keys, and glassy sound-design patches.
RipplerX is strongest when you want physical-modeling character without a large preset browser, effect rack, or deep modulation system getting in the way. Third-party demos consistently frame that simplicity as part of the appeal, especially for producers who prefer to shape the raw resonator sound and add their own external reverb, delay, or DAW modulation.
The current GitHub release provides separate Windows, macOS, and Linux ZIPs, and the repository remains public under GPL-3.0 with no paid tier or coupon-gated download. The macOS builds are unsigned and described by the developer as untested, so Mac users may need to remove the quarantine flag manually after installation.

Frequently Asked Questions
What kind of synth is RipplerX?
RipplerX is a physical modeling synthesizer based on modal resonators. Instead of playing back samples, it excites resonator models such as strings, plates, membranes, marimbas, and tubes to create struck, plucked, and resonant tones.
How close is RipplerX to Chromaphone or Ableton Collision?
The developer explicitly names Chromaphone, Collision, and Sai'ke Partials as key references, and several controls map to that style of resonator synthesis. RipplerX is simpler than Chromaphone 3 because it lacks the larger preset system, built-in effects, and broader modulation architecture.
Does RipplerX include effects or deep modulation?
No. Third-party demos point out that RipplerX stays focused on the resonator engine, with no built-in reverb, delay, LFO section, or arpeggiator, so it works best when paired with your DAW's modulation and external effects.
What should Mac users know before installing it?
The official README says the macOS builds are unsigned and untested. Users may need to remove the macOS quarantine flag from the component, VST3, or LV2 plugin bundle before their DAW will load it.
