RipplerX VST (Patreon)

In this video, I checked out RipplerX, a free and open-source physical modeling synthesizer that works on Windows, Mac, and Linux. It's a tiny 3MB plugin, but it delivers some great resonator-based sounds, similar to Pigments’ modal engine or Chromaphone.

What I really like about RipplerX is its straightforward design - no unnecessary effects, no clutter, just a pure sound engine. That means no built-in LFOs, envelopes, or fancy modulations, but that’s actually a plus because you can easily modulate everything with Bitwig’s modulators.

It features two resonators with various configurations (string, plate, drumhead, marimba, etc.), and you can either blend them together or feed one into the other for more complex textures. It’s perfect for percussion, plucks, bells, and ambient pads.

Key Features of RipplerX:

Small & lightweight – just 3MB, installs in seconds.

Fully open-source & free – no hidden costs.

Various resonator types – great for organic, percussive, and plucky sounds.

 Two resonators – can mix or feed into each other for complex timbres.

 Velocity mapping – allows expressive playing.

No built-in FX/modulation – but easy to modulate inside Bitwig, Ableton, or any DAW.

Things I Like About RipplerX:

No clutter – Just sound design tools, no unnecessary effects.

Simple UI – Everything is visible on one page. No menus, tabs, or hidden settings.

Fully customizable in Bitwig – Any missing features like LFOs or envelopes can be added with modulators.

Plays well with external reverb & delay – I prefer using my own effects anyway.

Things I’d Love to See Improved:

A darker UI theme – The current bright interface can be a bit intense.

More velocity mapping options – Right now, only a few parameters can be mapped.

A donation button! – The developer should allow people to support this amazing free synth.

How It Compares to Pigments & Other Synths:

While Pigments’ modal engine is great, it comes with a lot of extra LFOs, sequencers, and FX that I often don’t need. RipplerX strips things down to just the essentials, making it lightweight and CPU-efficient. If you love resonator-based synthesis but don’t want the bloat, this is a great alternative.

Where to Download RipplerX:
