KO II MIDI Programmer

KO II MIDI Programmer is a dark, performance-focused MIDI utility integrated into the MusicRig app for programming the Teenage Engineering EP-133 K.O. II from a desktop control surface. The app brings connection status, pad note assignments, pattern settings, MIDI channel controls, transport, sync options, velocity shaping, and a 16-step sequencer into one focused interface.

The design prioritizes studio readability inside the larger MusicRig workflow: high-contrast panels, clear hardware status, fast pad editing, real-time pattern controls, and a visual sequencer grid built for quick iteration. It is intended for musicians who want the immediacy of hardware with the precision of a software editor.

Key capabilities shown:

USB/MIDI device connection and port selection

16-pad note assignment grid for the EP-133 K.O. II

Tempo, velocity, gate, duration, pattern length, and MIDI channel controls

Step sequencer with active/rest states and per-step velocity values

Transport controls, clock sync, utility actions, and firmware/MIDI status

Role: product design, UI direction, hardware workflow design, and frontend prototype.
