Chordoo
Chord Sequence Generator
Generate MIDI-ready chord sequences for your productions. Our chord sequence generator creates patterns that drop straight into FL Studio, Ableton, Logic Pro, or any DAW. Stop programming chords by hand—let the generator do the heavy lifting.
What is a Chord Sequence Generator?
A chord sequence generator is a production tool that creates patterns of chords—typically 4, 8, or more bars—that work together harmonically. Unlike playing chords on a keyboard and recording them, a sequence generator gives you instant MIDI output that you can manipulate, transpose, and assign to any instrument in your DAW.
The real power of a chord sequence generator is speed. Instead of spending an hour finding chords that sound good together, you generate a sequence in seconds. Don't like it? Generate another. Found two chords you love but the others don't fit? Lock those chords and regenerate the rest. It's an iterative workflow that gets you to great-sounding sequences fast.
Chordoo's chord sequence generator outputs standard MIDI files, which means compatibility with every major DAW. The chords appear in your piano roll ready to be layered with synths, pianos, pads, or any instrument you want. From there, you can tweak velocities, adjust voicings, or use the sequence as-is.

Chord Sequence Generator Features
Genre-Based Sequences
Generate sequences tailored to Pop, EDM, Lo-fi, Hip Hop, Jazz, and more. Each genre uses characteristic chord patterns and voicings.
Instant Regeneration
Press spacebar to generate new sequences instantly. Cycle through dozens of options in seconds to find the perfect fit for your track.
MIDI Export
Export your chord sequence as a standard MIDI file. Compatible with every DAW—just drag, drop, and start producing.
Playback Preview
Hear your sequence before exporting. The built-in player lets you audition chord progressions to make sure they're right for your track.
Chord Locking
Lock individual chords in place while regenerating others. Build your perfect sequence by keeping what works and replacing what doesn't.
Zero Learning Curve
No music theory required. Generate professional chord sequences even if you've never studied harmony or can't read music.
Chord Sequence Workflow
Select Your Genre
Start by choosing a genre that matches your track. The generator uses different chord patterns and voicings for each genre—EDM progressions sound different from jazz or lo-fi.
Generate and Iterate
Hit generate (or press spacebar) to create a chord sequence. Listen back, and if it's not quite right, generate again. Most producers find their sequence within 5-10 generations.
Lock and Customize
Found a chord you love? Lock it. Then regenerate to find chords that work around it. This iterative approach lets you build the exact sequence you're hearing in your head.
Export to Your DAW
Click export to download your sequence as a MIDI file. Drag it into FL Studio, Ableton, Logic Pro, or any DAW. The chords appear in your piano roll, ready for production.
When to Use a Chord Sequence Generator
Starting a New Track
Generate a chord sequence as your starting point. Build your melody, bass, and arrangement around a solid harmonic foundation.
Breaking Creative Blocks
Stuck on a track? Generate fresh chord sequences to hear your project in a new harmonic context. Sometimes a different progression is all you need.
Learning Chord Patterns
Study the sequences the generator creates. Over time, you'll internalize common patterns and understand why certain chords work together.
Rapid Prototyping
Need to sketch out multiple track ideas quickly? Generate different sequences and rough out arrangements in minutes, not hours.
