Knobula is a London-based synthesizer company founded in 2021 by Jason Mayo, a record producer and remix engineer with a background working alongside artists like Mr C, Layo & Bushwacka, Adam Freeland, and Neneh Cherry. The brand designs digital Eurorack modules with a focus on polyphony, hands-on control, and a screen-free interface — a philosophy summarized in their tagline, "No screens, just big-screen sounds."

Knobula's catalog is built around compact polyphonic synth voices and performance-oriented utilities. The Poly Cinematic is an eight-voice polyphonic synth module aimed at lush pad and soundtrack textures, while the Monumatic packs an eight-voice MPE polysynth and a separate monosynth into a 12HP module. The Pianophonic is a wavetable polysynth inspired by the piano's string and hammer mechanism, and the Chord Pilot is a chord generator module. The lineup also includes the Kickain kick drum module, the Echo Cinematic effects module, and the Drum Farm, a performance-focused drum synthesis and sampling module.

The company has carved out a niche in the Eurorack market for cramming substantial digital polyphonic engines into small HP footprints without resorting to menu-diving, appealing to modular users who want full polyphonic capability alongside traditional monophonic patches.

Knobula has 3 products cataloged on Equipboard, including Modular Synthesizers.
