Open a MIDI file
Stay on-device. Start empty if you have no file, or try a public demo.
Off-grid notes, wild velocities, leftover gaps — the dirty AI-song export producers actually get.
A clean four-bar piano phrase you can transpose, quantize, or reshape immediately.
Drums, bass, and chords on separate tracks for mute, solo, and merge practice.
The same hook after quantize and velocity cleanup — the after shot for the messy export.
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
Drop a MIDI file, start empty, or open a public demo. Then edit notes, tracks, timing, velocity, programs, controllers, and pitch bend without uploading.
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.
Edit notes and tracks in one workspace
Open a Type 0 or Type 1 Standard MIDI File and choose a track in the piano roll. You can add notes, drag them to a new pitch or tick, resize their length, copy a selection, delete notes, and set velocity. Shift-click builds a selection for batch transpose, velocity, copy, or delete, while Undo and Redo treat each committed edit as one history step.
Track controls cover names, MIDI channels, program changes, mute, solo, visibility, and ordering. The event inspector exposes program changes, controller values, and pitch bend for the active track, so a small routing or expression correction does not require a full DAW session.
Preserve the events outside your edit
The piano roll is a view of a lower-level event timeline, not a replacement for it. Controller, pressure, SysEx, text, time-signature, and other non-target events remain in the MIDI document when you change notes or track settings. If you download before making an edit, EditMIDI returns the original source bytes.
After an edit, the compatibility check validates the structure before export. Always audition the downloaded file in the instrument, sampler, or DAW that will receive it because program mappings and synthesis differ between destinations.
Preview and recover local work
Use Play, scrub, loop, speed, mute, solo, and the metronome for a responsive timing check. The separate local action builds a full-duration note render as a 44.1 or 48 kHz WAV or MP3 with the bundled piano-and-hat SoundFont. Program changes, controllers, sustain, pitch bend, external plugins, and studio mix settings are not rendered.
Edited work is saved as one local recovery draft in IndexedDB on this browser. A newer draft replaces it, and Clear local recovery removes it explicitly. The editor and MIDI export continue to work without an account or a cloud connection.
When a focused MIDI editor is enough
Use EditMIDI when an existing file needs a precise correction, inspection, or clean export while the surrounding event timeline stays intact. Choose a full sequencer or DAW when you need instruments, arrangement, automation, effects, or a finished mix.
Questions people ask before they trust a browser MIDI tool
Is EditMIDI free?
Yes. Opening, editing, previewing, downloading MIDI, and creating a full-duration note render as WAV or MP3 in the browser are free and do not require an account. The render uses the bundled piano-and-hat SoundFont and does not apply program changes, controllers, sustain, or pitch bend. 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.
When should I use a focused MIDI editor?
Use EditMIDI to inspect or correct an existing file while preserving events outside the edit. Choose a browser composer or DAW when you need instruments, arrangement, automation, effects, or a finished mix.
