Common Questions About Editing MIDI Online

Get answers to common questions on editing, exporting, instrument playback, and file compatibility.

Q1: Is the MIDI editor free?

A: Yes — core editing features are free. We may offer additional advanced tools in future versions.

Q2: Can I input via a MIDI keyboard?

A: Not yet. MIDI keyboard input is not supported at this time; editing is done by dragging and manipulating notes in the interface. (It's on our roadmap.)

Q3: Is my file private?

A: Yes. Everything runs in your browser. Your file stays on your device.

Q4: Can I preview different instrument sounds?

A: Yes — we include multiple instrument voices (piano, guitar, strings, drums, etc.) that you can switch between in real time.

Q5: What kinds of MIDI files are best for this editor?

A: It's ideal for medium-complexity single-melody or small multi-track MIDIs. For very complex orchestration or large-track projects, consider splitting or using a full-feature DAW for finish work.
