Jaroslav Holub
I run Develop Device from Pilsen, Czech Republic. I build presets, plugins and production tools, and still take on selected mixing, mastering and custom sound work when the project fits.
A Studio Built Around Useful Tools
Develop Device started as a small studio and grew into a catalog of tools I use and refine myself: presets, drum MIDI, guitar tones, cabinet IRs, templates and plugins.
My background is rock and metal, so punch, clarity and weight are still part of the sound. The catalog has grown beyond that into synth presets, cinematic textures, electronic production and practical audio utilities.
How Develop Device Grew
From local studio work to a catalog of presets, plugins and production tools.
Getting Started
Early studio work, first clients and the sound that shaped the catalog.
