Create and Export MIDI Chord Progressions Online
A MIDI Chord Generator helps you compose, customize, preview, and export chord progressions as Standard MIDI (.mid) files for use in digital audio workstations. Instead of entering MIDI notes manually, you can build chord progressions in different keys and modes, adjust voicings and dynamics, preview them with realistic instrument sounds, and download a MIDI file that’s ready for your production workflow.
Whether you’re producing electronic music, writing songs, creating backing tracks, or experimenting with harmony, this tool provides a quick way to generate editable MIDI chord progressions directly in your browser.
How to Use the MIDI Chord Generator
Creating a MIDI progression only takes a few steps:
- Select a key root and scale mode.
- Choose a genre preset or start with an empty progression.
- Build a progression from 1 to 12 bars.
- Customize chord qualities, extensions, inversions, beat durations, and MIDI velocity values.
- Select a playback pattern such as Block Chords, Broken Arpeggio, Guitar Strum, or Ballad Pulse.
- Preview the progression using the built-in Web Audio player.
- Download the generated Standard MIDI (.mid) file for use in your preferred DAW.
The tool supports Major, Natural Minor, Dorian, Phrygian, Lydian, Mixolydian, Locrian, Harmonic Minor, and Melodic Minor scales, making it suitable for a wide range of musical styles.
If you’d rather build a progression before exporting it, the Chord Progression Calculator provides a complete progression-building workflow.
Customize Chords, Voicings, and MIDI Performance
The generator gives you detailed control over how each chord is created.
For every chord, you can customize:
| Setting | Description |
|---|---|
| Chord Quality | Major, Minor, Diminished, Augmented, Seventh, Suspended, and Added chords |
| Inversion | Root Position, 1st, 2nd, and 3rd inversions |
| Duration | Individual beat lengths for each chord |
| MIDI Velocity | Values from 1–127 for playback dynamics |
You can also choose from several performance styles that affect how the progression is previewed:
- Block Chords
- Broken Arpeggio
- Guitar Strum
- Ballad Pulse
These options make it easy to experiment with different musical ideas before exporting the final MIDI file.
If you’d like to examine the harmonic structure of your progression, the Chord Progression Analyzer can identify keys, Roman numerals, cadences, and harmonic functions.
Preview and Visualize Your Progression
Before downloading the MIDI file, you can preview the progression using the built-in Web Audio synthesizer.
The playback supports multiple instrument timbres while allowing you to adjust tempo between 40 and 220 BPM and loop the progression for easier evaluation.
The visual panel updates in real time and includes:
- A 2.5-octave piano keyboard.
- Six-string guitar fretboard diagrams.
- Harmonic tension flow visualization.
- Smart next-chord suggestions.
These visual tools help you understand how each chord is voiced before exporting the MIDI file.
To better understand how the progression functions within its key, the Roman Numeral Converter translates chords into functional Roman numeral notation.
Export MIDI Files for Any DAW
Once your progression is complete, simply download the generated Standard MIDI (.mid) file.
The file is created entirely within your browser using native client-side MIDI generation, making it ready for drag-and-drop import into compatible digital audio workstations.
You can continue editing the progression in applications such as:
- Ableton Live
- Logic Pro
- FL Studio
- Pro Tools
Genre presets also provide a fast starting point for styles such as Pop, Jazz, Blues, Canon, and Neo-Soul.
If you’re creating keyboard arrangements after exporting your MIDI file, the Piano Chord Progression Generator provides automatic piano voicings and accompaniment patterns.
Tips for Creating Better MIDI Chord Progressions
Small adjustments can dramatically improve a progression.
- Start with a key and scale that suit your musical style.
- Experiment with different inversions for smoother voice leading.
- Adjust MIDI velocity to create more natural dynamics.
- Compare playback patterns before exporting.
- Save multiple MIDI versions while exploring different ideas.
- Preview the progression before importing it into your DAW.
