Build your product on Desktop first.

The dev kit is a complete desktop environment. Drive a mocked Elk Stomp, load real VSTs into Sushi, and iterate as fast as you can save a file.

01
Stomp GUI

The Elk Stomp, on your desktop.

Every control on the physical pedal — OLED, encoders, eight pots, switches, RGB and red LEDs, the four-position rotary — emits the same events as the real hardware. Develop and debug without plugging anything in.

02
Sushi

Drop in VSTs.
Wire them to knobs.

Sushi is Elk's headless audio engine. Add plugins from a menu, patch them into a track, and map their parameters to the controllers on the mocked pedal — all without writing audio code. A growing library of open-source VSTs is one click away.

Time to put your work on hardware?

The same project runs unchanged on the Elk Stomp development board. Flash it, plug in, and hear it through real converters.
