Music Producer
5.0
I dropped in a rough piano recording and had an editable MIDI track in minutes. Fixing notes afterward was much faster than recreating the part by hand.
Songwriter
5.0
I usually lose ideas after recording a quick voice memo. Turning a melody into MIDI gives me something I can actually keep editing.
Beatmaker
5.0
Being able to turn audio into MIDI and immediately tweak the notes makes sampling ideas much more flexible.
YouTube Creator
5.0
The MIDI visualizer saves me from moving files between several tools just to make a simple piano-roll video.
Composer

The text-to-MIDI tool is useful for getting a starting point quickly. I can generate an idea, edit it, and shape it into something that actually feels like mine.
One account, one studio — convert an MP3 in the morning, visualize it at noon, edit it at night. No new logins, no new paywalls.
FAQ
Questions & answers
01
Is MIDIdock free to use?
Yes. Your first task is completely free, no sign-up needed. Registered users get free daily quotas; heavy users can buy single-task packs or subscribe.
02
Do I need to install anything?
No. Every tool runs entirely in your browser.
03
Which audio formats can I convert to MIDI?
MP3, WAV, and most common audio formats. You can also hum a melody or upload sheet music as PDF.
04
How accurate is the conversion?
Our engine detects pitch and timing from your recording. Clean, single-instrument audio gives the best results — and you can fine-tune every note in the built-in editor.
05
Can I edit the MIDI after conversion?
Yes. Open any result directly in the MIDI Editor with one click.
06
Do you keep my files?
Conversion happens in your browser, so your files are never uploaded just to convert. Free accounts don't keep history — subscribe for cloud storage and project history.
07
How is this different from a DAW?
MIDIdock is a fast online toolkit for specific MIDI jobs, not a DAW replacement. Convert, generate, visualize, or quick-edit here, then export to your DAW.
08
Can I use the MIDI commercially?
Yes. MIDI you create or convert with MIDIdock is yours to use however you like, including commercial releases.
