MIDI Copilot
AI-powered chord progressions, melodies, and basslines
Free AI bassline generator
Create groovy, rhythmic basslines that perfectly complement your chord progressions. Our AI bassline generator produces bass patterns in any key and tempo.
The bassline generator analyzes your chord progression and creates bass parts that follow the harmonic structure while adding rhythmic interest. Choose from whole-note patterns to complex eighth-note runs.
Edit any note in the bass piano roll — move, resize, add, or delete notes. Lock your bassline and regenerate chords and melody around it. Export everything as a multi-track MIDI file.
