Knobula Chord Pilot

MIDI chord explorer with 192 memories and arpeggiator

12 HP Eurorack module

Chord Pilot is a MIDI chord generator, explorer, and arpeggiator in 12HP. It generates chords by manipulating virtual finger positions on a musical grid, then conforming them to scales. Features 192 chord memories (3 sets × 8 banks × 8 chords), 8 illuminated preset buttons arranged in a circle, a chord progression sequencer (Orbit mode), and a multi-style arpeggiator. Designed for experimental chord discovery rather than traditional music theory — turn knobs to explore harmonic space and save results to presets. Works with any polyphonic MIDI synth.
