AI-song MIDI cleanup
Clean a messy Suno MIDI export
Some AI-generated or converted MIDI can have loose timing, uneven velocity, split tracks, or gaps. Open the messy demo or your own file, then clean it before a DAW.

Open a MIDI file
Stay on-device. Start empty if you have no file, or try a public demo.
Your file stays on this device unless you explicitly use Creator Cloud. After an edit, one local recovery copy is saved in this browser until you replace or clear it.
2. Clean
Quantize, transpose, fix velocity, merge another MIDI, or add notes.
3. Export
Preview, undo if needed, then download and drop the file into a DAW.
What this tool changes
Some AI-generated or converted MIDI can have loose timing, uneven velocity, split tracks, or gaps. Open the messy demo or your own file, then clean it before a DAW.
What stays in your MIDI
Events outside the selected operation remain in the low-level timeline. Downloading before any edit returns the exact source bytes.
Drop the export into a DAW
- Download the edited file. The name starts with editmidi- so it is easy to spot in a DAW project.
- In FL Studio, Ableton, or Logic, create or open a MIDI track and import that .mid onto the clip or arrangement.
- Audition the destination instrument. MIDI is instructions, so the sound comes from the synth you attach in the DAW.
A before and after you can repeat
Open demo: messy Suno export, choose a timing grid and note-on velocity, then select Clean Suno MIDI once. Compare it with Open demo: cleaned Suno hook. The download name starts with editmidi- so the cleanup is visible in a project folder.
Keep, rename, or reorder split tracks when an export separates a hook into several parts. This is a cleanup bench, not a generator that claims to write the song for you.
Questions people ask before they trust a browser MIDI tool
Is EditMIDI free?
Yes. Opening, editing, previewing, and downloading MIDI in the browser is free and does not require an account. Creator Cloud is optional and includes 60 reviewed AI MIDI transformations per billing month.
Does my MIDI file get uploaded?
No. Local tools read the file in this browser. A file reaches our servers only if you explicitly save it to Creator Cloud.
Can ChatGPT make or edit a MIDI file?
A chat model can talk about MIDI, but it cannot open your .mid, keep every event, or give you a piano roll. EditMIDI is the editor you use after an export or a draft transcription.
How is this different from Signal?
Signal is a browser composer: blank songs, sketching, SoundFonts, and a DAW-like path. EditMIDI is a surgical editor. Untouched downloads return the original bytes. After an edit, events you did not change stay in the file.
