USB MIDI controller
Sketchy Circulate
A compact controller based on the Ottopot and Gerotakke idea, rebuilt around RP2040 with tight, workable knob spacing and dual-wiper potentiometers for a high precision encoder feel.
14-bit MIDI control
Dual-wiper potentiometers provide higher resolution control while keeping the immediacy of a knob-based hardware interface.
RP2040 hardware
The controller is smaller than Ottopot, with knobs set closer together but still comfortable for live use and detailed editing.
Web editor
The companion app connects in the browser to set colors, CCs, and behaviors, then saves settings directly to the device over SysEx.
