Prok Modular is a small modular synthesizer outfit founded by Martin Wood-Mitrovski (Button Masher) and Steven Grimley-Taylor (Medium Cheese), focused on drum synthesis hardware and software for the Eurorack format. The brand's lineup centers on four compact DSP-based percussion modules — Bassdrum (BD), Snare (SN), Hi-Hat (HH) and Clap (CP) — built around a modified version of Tom Whitwell's Music Thing Modular Radio Music open-hardware design (released under a CC-BY-SA license).

The modules are best known for a "2D patch morphing" approach, where each unit can morph continuously between four virtual-analog drum voices across X and Y axes under voltage control, with a characteristic 12-bit lo-fi crunch. They're sold both fully built and as DIY kits, primarily through UK retailer Thonk, and the company also distributes a free patch editor for Mac and Windows along with VCV Rack software versions of the modules. Endorsements have included a quote from electronic musician Cristian Vogel ("Put a Prok on it!").

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