UVI Rumble

Description

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.

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.

• Body – Sub-bass through bass. Weight, punch, and the structural low end of a sound: home to 808s, sub kicks, and the gravitational core of a track.
• Character – Low-mids through upper-mids. Tonal identity, presence, and harmonic richness: the recognizable middle of a sound, where its timbre lives.
• Air – Upper-mids through treble. Shimmer, articulation, and top-end motion: where a sound gets its lift, edge, and detail.

Nine Oscillator Models

A bank of nine synthesis engines, each tuned for a different sonic territory:

• Analog features a dual-oscillator design with sync, pulse-width and band-limited antialiasing
• Morpho handles phase distortion with nonlinear shape and morph controls.
• Phonem generates vocal formant peaks for talking and singing tones.
• Fold brings West-coast wavefolding with a vactrol-modeled lowpass gate.
• Timbral is a wavetable engine with 90+ tables and six phase-distortion modes.
• Noise offers 90+ curated noise sources.
• Sampler plays from a curated library of mono bass samples with user-import support.
• Kick is a specialized drum synthesis engine with transient sampling and FM tone.
• Prism runs dual-carrier, dual-modulator FM with cubic nonlinearity.
