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,andAireach 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 youthree.
An architecture engineered for complex bass sound design
Visible at a glance, deep on every layer
Rumble's interface is organized around the three-band signal flow.
Per-band modules
Body
Character
Air
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.

10wave-shaping modes with per-band AM injection
Each band has an independent wave-shaper positioned after the oscillator. Ten nonlinear transfer functions cover the territory from gentle saturation to aggressive fold and ring modulation
Punch and compression
Clipper
Warm musical folding
Sine
Dense harmonic richness
Foldback
Hyperfold
Fundamental doubling
Rectify
Soft saturation with built-in rolloff

Noise
Subtle-to-aggressive ring modulation
Soft
Hard
TheAM Injectorroutes amplitude modulation between bands, Body's signal can shape Character's level, Character can pump Air, for rhythmic interaction that lives inside a single voice.
10effects with feedback loop
Each band has its own effect slot that can be filled from 10 custom FX chains:
Morphs through impulse-modeled speaker enclosures from small combos to large stacks
Cabinet
Offers four algorithms across Digital, Tape, Spin, and Velvet
Delay
Digital layers fuzz, dispersion, chorus, frequency shifting, and sample-rate reduction for complex lo-fi
Digital
A spectral transformation engine, phaser, chorus, and drive woven into one
Neuro
Offers five algorithms from algorithmic to convolution plate, spring, and bloom-style swell
Reverb
Combines pitch and frequency shifting with spectral destruction
Shifter
Focuses on transient-aware compression and saturation
Smasher
Blends comb filtering and Bode frequency shifting for liquid metallic motion
Drift
Runs a destructive distortion chain, fuzz, wave-shape, spectral shift, convolution
Trasher
Offers modulated delay with optional pitch erosion
Chorus
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.
Expansive sound design
Rumble ships with an extensive factory library organized by sonic character:
Low-end basics and sub work
808
Aggressive bass voices
Growl
Modulated and rhythmic basses
Wobble
Distorted and gritty character
Dirty
Cutting, articulated basses

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.
Forged with passion
Rumble’s factory library was crafted by working sound designers and genre-specialized producers each infusing their own distinct voice, resulting in an expansive sonic experience fueled by passionate artists.
