UVI Rumble - Multi-Band Bass Synth - A First

UVI's new Rumble instrument tackles bass sound design by dividing the frequency spectrum into three separately synthesized bands, each running its own oscillators, filters, and effects before they converge at a shared output stage. 
The three-band architecture is the thing to pay attention to here. Most bass synths treat the sound as a single object and let you shape it with EQ and compression after the fact. Rumble bakes that spectral thinking into the synthesis stage itself - you're not just EQing a sound, you're building different sounds in different frequency bands and blending them.

We've tried it and can confirm its pretty neat, dragging the crossover point for each band can drastically change it - as well as setting the gain for each. It is like messing with a multi-band compressor!

Features

• Three frequency-based engines: Body (sub/low end), Character (mids/harmonics), Air (top end/articulation) - each a full synth engine running in parallel
• 9 oscillator models: virtual analog, wavetable, PD, FM, drum, vocal formant, wavefolding, and more
• 6 filter circuits including vintage lowpass, multi-resonant designs, phaser/flanger hybrids, and a formant/vowel filter
• 10 effect chains per band, each with a feedback loop for self-resonating processing; includes cabinet sim, reverb, delay, transient compression, distortion, and spectral tools
• 33 modulation sources: 16 DAW-automatable macros, 4 LFOs with a complex-source mixer, 2 x 128-point MSEGs, 3 chaotic random generators, plus a full mod matrix
• 500 factory presets built by working sound designers and genre producers
• VST3, AU, AAX, standalone (64-bit), NKS compatible; authorises on up to 3 computers or iLok keys

Launch price: $99/99€ until June 28th, 2026 (regular price $199/199€); SonicBundle owners get an extra $10/10€ voucher
