Overview

MIDIGEN is a web-based MIDI melody generator and chord progression tool for musicians, producers, and beatmakers. It creates original MIDI output using scale, key, tempo, and complexity settings so users can turn an idea into an editable musical sketch quickly.

The site positions MIDIGEN as a practical composition helper rather than a sample library. It emphasizes royalty-free MIDI output, no sign-up, and export-ready files that can be dropped into a DAW for further editing, arrangement, or sound design.

Features

Scale and key selection

Choose the musical scale and key to set the tonal center before generating a melody.

Composition controls

Set the number of bars, tempo, and note duration to shape the length and pacing of the result.

Optional melodic variation

Optionally include rests, chords, and arpeggios to add variation and harmonic detail.

Royalty-free MIDI generation

Generate original MIDI output that the site says is royalty-free and editable in a DAW.

DAW-friendly export

Export clean MIDI files for drag-and-drop use in common digital audio workstations.

Instant access

Use the site without signing up; the home page says there are no subscriptions, limits, or watermarks.

Use Cases

  • DAW-based production

  • Music theory practice

    Experiment with scales, keys, tempo, and note duration to compare how small parameter changes affect the musical result.

  • Education and demonstrations

    Use the output as a teaching or demonstration aid for chords, arpeggios, rests, and other composition concepts.
