UVI introduces Rumble Multiband Bass Synthesizer
UVI has announced the release of Rumble, a new multiband bass synthesizer designed for electronic music production. The instrument introduces a three-engine architecture that separates sound generation into dedicated frequency bands, allowing users to shape low-end weight, harmonic character and high-frequency detail independently.
A unique approach to synthesis
Rumble is built around three frequency-focused synthesis sections named Body, Character, and Air. Each section operates as a complete synthesis engine with its own oscillators, waveshapers, and effects, before being combined through shared processing stages, including filtering, compression, and equalisation. The Body engine is intended for sub-bass and low-end foundation; Character focuses on tonal content and harmonics, while Air is designed to add articulation and high-frequency presence. The instrument includes nine oscillator models: virtual analog, wavetable, phase distortion and FM, alongside drum and vocal-inspired sound generation options. Six filter types are also included, ranging from vintage-inspired low-pass designs to more specialised formant and multi-resonant filters.
Modulation and Effects
Rumble ships with ten effects chains that include distortion, cabinet simulation, reverb, delay, transient processing, and spectral effects. Each effect chain can be routed through a feedback loop, enabling more experimental and self-resonating processing techniques. The synthesizer offers 33 modulation sources, including four LFOs, two multi-segment envelope generators, random generators, 16 DAW-automatable macros, and a dedicated modulation matrix for parameter routing.
Factory library
Rumble includes a factory library of 500 presets intended both as a source of ready-to-use sounds and as a starting point for deeper sound design.. Rumble is available now at an introductory price of $99 / €99 until 28 June 2026. Owners of SonicBundle are also eligible for an additional voucher discount.
