Free Online MIDI Editor

Yep — completely free. No hidden fees, no credit card, no account needed. Make as many MIDI files as you want and download every single one. There are no usage limits. It's free today and it'll stay that way.

A MIDI editor lets you create and tweak MIDI data — basically the digital instructions that tell music software which notes to play, how loud, and for how long. Think of it like writing sheet music on a grid. You place notes visually, and the tool turns them into a file that any music app can read and play back with whatever instrument sound you choose.

Click on the piano roll grid to place notes. Use the Draw tool to add them and the Eraser to remove them. Set your tempo with the BPM slider and control how hard notes play with the velocity slider. Press Play to hear your piece. When you like what you hear, click Download MIDI and you'll get a standard .mid file ready for any DAW.

A piano roll is a visual grid that music software uses to show and edit MIDI notes. Pitch goes up and down (low notes at the bottom, high at the top), and time moves left to right. Each note shows up as a colored block on the grid. It's the standard way to write and edit MIDI in pretty much every major DAW out there.

All of them. You get a standard .mid file that works in Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, Studio One, Pro Tools, Reaper, Bitwig, Reason, and more. It also opens in notation apps like MuseScore, Sibelius, and Finale. No conversion needed — it just works.

Nope. The MIDI editor runs entirely in your web browser. Nothing to download, install, or update. It works on any device with a modern browser — Mac, Windows, Linux, Chromebook, iPad, or phone.

You can. The editor works on mobile browsers. For the best experience, a tablet or desktop gives you more room to see the piano roll and place notes precisely. But your phone works in a pinch.

Not even a little. The visual piano roll lets you create music by ear — place notes, listen, and adjust until it sounds good to you. A lot of people actually pick up music theory just by playing around with the editor, seeing how intervals and chords look and sound together. It's a surprisingly good way to train your ear.

Velocity is how hard a note gets played. In MIDI, it's a number from 0 to 127 — higher means louder and more intense, lower means softer and gentler. The editor lets you set velocity with a simple slider, so you can add dynamics to your music without ever touching a keyboard.

Absolutely. Slide the BPM control and the playback speed changes right away. Your notes stay exactly where they are on the grid — only the timing between them shifts. So you can try different tempos without redrawing a single note.

Audio is a recording of sound waves — like a photo of a performance. MIDI is a set of instructions — more like sheet music for computers. Audio captures what something sounded like. MIDI captures what notes were played, how hard, and for how long. Because MIDI is just data, you can edit every note, swap instruments, change the key, and adjust the tempo after the fact. You can't do that with audio.

You retain any rights you already hold in notes and source material you provide. BeMusic grants plan-based rights to generated or converted output: free and Creator are for personal, non-commercial use, while Pro and Studio include a commercial-use license for eligible output. You still need rights to any imported source material.

You can. Drag a .mid file onto the editor or use the import button. The piano roll loads every note and keeps the pitch, timing, and velocity intact. Edit whatever you need, then export a fresh file. It's handy for fixing timing issues or transposing a part before sending it to your DAW.

Right now the editor focuses on point-and-click note entry so anyone can use it — no hardware needed. MIDI keyboard input through the Web MIDI API is on our roadmap. For now, draw your notes on the piano roll and export to your DAW when you want to record with a keyboard.

You get up to 16 bars on a single track, which covers most sketching and prototyping needs. If you want multi-track arrangements, export your .mid file and layer additional parts in your DAW. The goal here is fast idea capture, not replacing your full production setup.
