Rumble

Rumble - Multiband Bass Synthesizer

A multiband bass synthesizer plugin with three frequency-based engines, each with discrete oscillators, wave-shapers and effects. Designed for bass and beyond.

Three parallel engines. One unified sound..

Rumble was designed to meet the needs of contemporary bass: the weight, punch, articulation, and movement that bass-led music demands. To deliver that, Rumble's architecture treats each frequency band as a full synthesizer engine. Body, Character, and Air each carry their own oscillator, wave-shaper, and effects, then converge through a shared filter stage, multiband compressor, and master EQ, to produce a powerful, unified voice.

The result is the first multiband synthesizer, built for bass from the ground-up. Layered sub-, mid-, and high-frequency content stays structurally separate, which means low-end weight, midrange definition, and top-end air can each be sculpted on their own terms.

The architecture itself goes deeper: vocal-formant synthesis, drone textures, percussive transients, cinematic motion, vintage analog warmth, all live within the same per-band approach.

The factory library is built by sound designers and genre-specialized producers, with a sprawling range of presets covering everything from 808s and wobbles to drones, motion sequences, and abstract textures.

Most synths give you one engine. Rumble gives you three.

PER-BAND SYNTHESIS ENGINE

Three bands. Three synth engines. Each band carries an independent oscillator, wave-shaper with cross-band AM injection, and an effect slot, chosen and tuned per band, then merged through a shared filter and master section. The engine was designed against the weight, punch, articulation, and motion that bass-led production demands, unlocking precision and creativity that other architectures simply can't reach.

Nine oscillator models
(Analog · Morpho · Phonem · Fold · Timbral · Noise · Sampler · Kick · Prism).

Ten wave-shaping modes with per-band AM injection
(Clipper · Sine · Foldback · Hyperfold · Rectify · Damped · Diode · Noise · Soft-Ring · Hard-Ring).

Ten effects with feedback loop
(Cabinet · Delay · Digital · Neuro · Reverb · Shifter · Smasher · Drift · Trasher · Chorus).

GLOBAL TOOLS

Six filter circuits
(Analog · Variable · Ripple · Swirl · Scream · Formant).

Modulations

Thirty-three modulation sources route to virtually any parameter, with two modulation slots per target and bipolar ratio control.

Master section

Multiband Compressor

A three-band compressor aligned with Body, Character, and Air. Eight character modes span the territory from transparent leveling to aggressive multiband compression:

Master EQ

A four-band parametric equalizer with real-time spectrum analyzer. Drag control points to adjust frequency and gain; right-click to change filter type across Low Pass, High Pass, Notch, Low Shelf, High Shelf, and Peak.

Bass and beyond

A factory library shaped by working sound designers and genre-specialized artists. Built to demonstrate the engine's full range, from the genres that called it into being to the territory it opens up.

Every sound in Rumble was crafted across all three bands. Sub anchored in Body, grit and movement shaped in Character, the transient snap in Air. Every band does its job without fighting for space. Bands drive each other, one frequency breathing against the next, for movement no single-band synth can produce. Immense, riveting bass voices, form-fitted to their sonic environments in a way only Rumble can deliver.

Rumble's multiband synthesis gives musicians a powerful new tool to create massive sounds with laser-like precision. Craft three discrete engines, forge them into one, and discover new realms of inspiration for bass and beyond.
