What is it?
A Bluetooth-enabled synthesizer module with companion iOS mobile App.

My Roles
  • UX Designer: Mobile, Hardware, Circuit / Faceplate Layout & Fabrication
  • Full Stack Developer: React Native, Bluetooth Low Energy, Arduino

None of the Eurorack sequencers available today offer the distinct feature set and/or hardware size that optimizes workflow.

I executed hands-on market research, user interviews; the results of which I used to inform wireframes, flow diagrams, and initial prototypes for the proof-of-concept of the mobile app. I built the working mobile app with React Native.

I designed & manufactured the BLE connected hardware device over an iterative process based on user tests, refining the layout, scale, and circuit design resulting in a minimal-footprint / maximal-feature niche instrument.
