2. What Is UVI “Rumble”?
Rumble is UVI’s first multiband bass synthesizer, treating the low, mid, and high frequency bands as three independent synth engines. Developed as a standalone software instrument — the first since Falcon — it runs on its own without requiring Falcon or UVI Workstation.
💡 How it differs from a typical synth
A conventional synthesizer builds a tone with a single engine and then shapes it afterward with EQ and effects. Rumble instead splits the sound into three frequency bands and designs each one separately as an independent synth engine. This unprecedented architecture lets you control the weight of the lows, the presence of the mids, and the air of the highs independently.
Three Synth Engines — Body / Character / Air
Rumble’s signature feature is its unique architecture that splits the tone into three bands — low, mid, and high — and treats each as an independent synth engine. Each engine has its own dedicated oscillator, wave shaper, and effects, and they are unified into a single sound through a shared filter, multiband compressor, and master EQ.
In addition, the AM Injector feature applies amplitude modulation between the bands, so the Body signal can drive the level of Character, and Character can drive Air — creating complex, organic interaction within a single tone.
Sound Design Features
While designed for bass, Rumble also works as a full-fledged sound design environment. By combining each engine’s oscillators, wave shapers, and effects, it handles everything from 808s and modern bass music to drones, motion sounds, formants, and cinematic textures.
Modulation
Rumble features 33 modulation sources and a flexible modulation matrix. Almost any parameter can be assigned modulation, covering everything from static basses to lively sound design.
- 16 Macros: Control multiple parameters at once. DAW automation supported.
- MIDI control: Supports velocity, mod wheel, key tracking, and pitch bend.
- 3 ADSR envelopes: Support curve editing for each stage and legato playing.
- 4 LFOs: Adjustable waveform, symmetry, and pulse width. Includes an LFO Mix feature that combines all four.
- 2 MSEGs: Create rhythmic patterns and long-form changes with up to 128 breakpoints.
- Random & Analog Drift: Random modulation applying S&H and chaos theory (Lorenz / Rossler), plus a recreation of the subtle drift characteristic of analog circuits.
Master Section
A powerful master section unifies the three independent engines, refining the sound built with Body / Character / Air into a single polished tone.
Multiband Compressor
Optimized for the three-band Body / Character / Air structure. From transparent leveling to powerful EDM-style processing, it offers eight character modes: Clean / FET / HiFi / Opto / OTT / Punch / Radio / Sub & Click.
Master EQ
A 4-band parametric EQ with a real-time spectrum analyzer. It supports low-pass / high-pass / notch / low-shelf / high-shelf / peak, letting you fine-tune the final tone while visually checking the frequency balance.
Preset Library
A vast collection of factory presets created by front-line sound designers and genre-specialist producers. They work both as ready-to-use sounds and as starting points for new sound design.
Although Rumble is designed for bass, its sound library is not limited to bass. It can be used across a wide range of production contexts, including electronic music, film scoring, game music, and sound design.
