The Ultimate Free MIDI Generator — No Sign-Up Required

MIDY is a free AI MIDI generator that runs entirely in your browser. No account, no downloads, no limits. Generate royalty-free melodies, chord progressions, and arpeggios in seconds and drag them straight into your DAW. Whether you're battling beat block or exploring a new genre, MIDY gives you the starting point you need.

How It Works

  1. Pick a Mood: Choose from 7 emotional modes — Happy, Sad, Chill, Hypnotic, Dark, Dreamy, or Epic. Each one uses a different musical scale and set of chord progressions to match the vibe.
  2. Customize: Select your key, tempo (BPM), length (2–16 bars), and melody style (Melody, Arpeggio, or Piano Comp). Preview your creation with the built-in piano roll and synth playback.
  3. Download: Get a standard MIDI file (.mid) with separate tracks for melody (channel 1) and chords (channel 2). Drag it into any DAW and assign your own instruments.

7 Moods for Every Genre

Built-In Piano Roll

Every generation is instantly visualized in a live piano roll. Melody notes appear in pink, chord notes in purple. A playhead follows along during playback so you can see exactly what's happening musically. It's the fastest way to evaluate an idea before downloading.

Works with All Major DAWs

MIDY generates universal Standard MIDI Files (.mid). Whether you use Ableton Live, FL Studio, Logic Pro, Cubase, or GarageBand, simply drag and drop the file to start creating.

Unlike audio loops, MIDI gives you 100% control. Change the instrument to any VST, transpose the key, edit the notes, and make the music truly yours.

Frequently Asked Questions (FAQ)

Are the melodies generated by MIDY royalty-free?

Yes, absolutely. Every melody and chord progression you generate with MIDY is completely royalty-free. You can use them in your personal and commercial productions (beats, songs, jingles, etc.) without any legal concerns or additional costs.

Do I need to create an account to use MIDY?

No. MIDY is completely free with no sign-up, no login, and no usage limits. Just open the page and start generating. Everything runs in your browser — nothing is uploaded to any server.

How do I use the MIDI files in my DAW?

After clicking "Download MIDI," drag the file directly into your DAW's timeline (Ableton, FL Studio, Logic Pro, etc.). The file contains two tracks: the melody on channel 1 and the chords on channel 2. Assign your favorite virtual instruments to each track.

Which mood should I use for Trap, Lo-fi, or EDM?

Here's a quick guide:

  • Trap / Drill: Try "Dark" (harmonic minor tension) or "Hypnotic" (repetitive pentatonic patterns) at 70–90 BPM.
  • Lo-fi / R&B: "Chill" with Piano Comp is the go-to — jazz-inspired chords with swing feel.
  • EDM / Techno: "Hypnotic" or "Epic" in Arpeggio mode at 120–140 BPM.
  • Cinematic / Trailer: "Epic" for heroic themes, "Dark" for tension, "Dreamy" for ambient atmosphere.
  • Pop / Indie: "Happy" or "Dreamy" for uplifting, melodic content.

What's the difference between "Melody", "Arpeggio", and "Piano Comp"?

  • Melody: Generates a human-like melodic line using phrase-based AI logic (A-A'-B-A structure) that fits the selected mood's chords.
  • Piano Comp: Generates both chords and melodic fills together, like a session pianist. Perfect for quickly creating a complete musical idea.
  • Arpeggio: Plays the individual notes of each chord in a repeating pattern. Great for synth lines, bass patterns, and rhythmic backgrounds.

What is the piano roll and how does it work?

The piano roll is a visual display that appears after every generation. It shows your melody notes (pink) and chord notes (purple) on a grid where the horizontal axis is time and the vertical axis is pitch. During playback, a white playhead moves across it so you can see each note as it sounds.

Why does the preview sound like a synth and not a piano?

The in-browser preview uses a lightweight synthesizer (Tone.js) so the page loads instantly on any device. Each mood has its own synth character — Dreamy sounds airy with reverb and chorus, Dark sounds heavy with filtered sawtooth waves, etc.

The MIDI file you download contains pure note data. Load it into your DAW and assign any instrument you want — piano, guitar, strings, or any VST.

What is a MIDI file and why is it useful?

A MIDI file is not audio — it's data. It's like sheet music for computers, telling your DAW what notes to play, when to play them, and how hard (velocity). This gives you 100% control: change the key, edit notes, adjust tempo, and swap instruments freely.
