Motivic MIDI

Chord Progression Generator with MIDI Output

About the App

Motivic MIDI is a chord progression discovery tool designed to help you find unexpected, highly musical chord combinations. Set your constraints—Key, Scale, Mode, and Chord Filters—and find musical inspiration.

Built on Mathematics

Random within constraints. Generate triads, 7ths, and 9ths across dozens of diatonic, melodic minor, and synthetic scales. Find the exact voicings and rhythmic figurations you need to spark your next track.

Built on Music Theory

Visualize the theory behind the audio. Motivic MIDI features real-time visual musical staff notation and an interactive piano roll that explicitly reveals the harmony as you audition chords.

Zero-Latency Audio

Audition chords over 4-bar loops with diverse rhythmic figurations using a custom, wait-free C++ Oboe audio engine designed for professional-grade stability and zero-latency performance.

MIDI Options

Never trap your data. Save and seamlessly export your sessions as standard .mid files to your device, or route MIDI directly via USB to control external hardware synthesizers and PC DAWs in real-time.
