Local playback

MIDI player online

Load a MIDI file and hear a small piano-and-hat SoundFont preview. Mute, solo, loop, and scrub without uploading, then turn the note timeline into a local WAV or MP3 when you need a downloadable audio file.

Open a MIDI file

Stay on-device. Start empty if you have no file, or try a public demo.

Choose MIDI file

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.

What this tool changes

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.

Audition a MIDI file without uploading it

Open a Type 0 or Type 1 MIDI file to inspect its track layout and tempo map. Play or pause the timeline, drag the scrubber to a new position, change preview speed, or define a loop while the source file remains on this device.

Mute isolates what you do not want to hear; Solo focuses the preview on selected tracks. Track names, channels, programs, note counts, and editable channel events remain visible in the shared workspace when you need to investigate why a part sounds or routes differently than expected.

Use playback as a timing check

The player schedules MIDI notes against the file tempo map and offers a simple metronome click. Preview controls do not rewrite the MIDI event timeline. Downloading an untouched file returns its original bytes.

Playback uses a small bundled piano-and-hat SoundFont with an oscillator fallback. Local WAV and MP3 note rendering uses that same limited bank and never uses the oscillator fallback. Program changes, MIDI controllers including sustain, volume, expression, and pan, pitch bend, external instruments, effects, and mix settings are not rendered, so use a destination device or DAW when those details matter.

Move from inspection to a focused change

If the timing is correct but the key is wrong, open the transpose tool. If playback is consistently too fast or slow because of its embedded tempo events, use the tempo changer. For note, track, controller, program, or pitch-bend changes, continue in the full online MIDI editor.

Questions people ask before they trust a browser MIDI tool

Is the MIDI player free?

Yes. Load a file, mute or solo tracks, loop a range, and preview with the bundled SoundFont. No account is required.

Does playback upload my file?

No. Preview and WAV or MP3 note rendering stay on this device. Preview is the responsive timing check; Render and download creates a full-duration note render from the same limited bundled SoundFont. Program changes, controllers, sustain, and pitch bend are not rendered.

Why is this not a full GM bank?

The default bank is a small piano-and-hat SoundFont so the Player page sounds like an instrument, not a raw oscillator. If that file fails to load, the player falls back to the oscillator and says so.

Keep the same file

Every page runs on the same browser MIDI engine, so you can move between them without uploading or re-importing your file.
