Our online MIDI editor lets you open, edit, and enhance any MIDI file (.mid, .midi) in just a few seconds, right from your browser.
You can fine-tune your music data: move notes, change their duration, adjust velocity, correct the rhythm, or rework your instrumental tracks with ease.
Edit each note individually: position, duration, pitch, and velocity. Fine-tune your compositions with precision right in the editor.
Easily rearrange your sequences: move notes, duplicate patterns, or delete elements with just a few clicks.
Refine the musical performance by adjusting the dynamics of the notes and expression settings for a more natural and musical result.
Work on multi-instrument projects: add, delete, or edit tracks independently to structure your arrangement.
Speed up, slow down, or correct the tempo of your MIDI file. Optimize the rhythmic placement of your notes for a clean and consistent sound.
More than 60 soundfonts are available in the editor. Edit the soundfonts for each track and customize the instruments heard in your MIDI.

Use the editor on a computer, tablet, or mobile device for a seamless experience tailored to each screen.
Select the notes you want to edit, then adjust them directly in the interface: position, pitch, duration, velocity, rhythmic placement, duplication, or deletion. You can also work track by track, isolate an instrument, add a new track, modify expression parameters, or edit a specific section in a loop.
Move, stretch, or delete notes on a precise horizontal timeline. Control velocity, tempo, and quantization with the flexibility of a digital audio workstation (DAW)—right in your browser.
