A real transcription in LumaKeys: audio in, playable falling notes out.

How it works

  1. 1

    Drop the recording in

    Drag a piano audio file into LumaKeys — a voice memo from your phone, an old performance, a practice take. No account, no upload form, no queue.

  2. 2

    It becomes MIDI, on your Mac

    LumaKeys transcribes the recording on-device into editable MIDI: every note with its timing and velocity. Your audio never leaves your computer.

  3. 3

    Play it, fix it, keep it, export it

    The result is a real piece in your library: falling notes you can learn from, a piano roll where you can correct or reshape anything, and export as MIDI or as a video up to 4K.

On-device vs. online converters

Many online piano converters are built around upload, conversion, and download — often as sheet music, PDF, MusicXML, or MIDI. LumaKeys is built differently: transcription happens on your Mac, and the result is a piece you can immediately play, edit, and export.

Aspect Online converters LumaKeys
Where transcription runs Their servers — you upload your audio On your Mac — nothing uploaded
Pricing model Subscription or per-song credits 5 free · unlimited with Pro ($69 founding · $99 regular)
What you get back A MIDI / PDF / MusicXML download A playable, editable piece in your library
Fixing mistakes Re-import the file into another editor Built-in piano roll, right there
What happens after You need more tools to learn or present it Learn it from falling notes, style it, export video

Compared July 2026. Cloud tools are the right pick if what you want is printable sheet music (PDF/MusicXML) — that's their focus, and LumaKeys doesn't do notation.

What people transcribe

Write down what you played

You improvised something good and only have a phone recording. Transcribe it, clean it up in the piano roll, and it's a piece you can keep and relearn.

Recover your old recordings

Performances from years ago become editable MIDI — loop them, slow them down, and learn your own playing back.

Learn public-domain classics

Chopin, Scriabin, Rachmaninoff — recordings of public-domain works you have rights to become falling notes you can practice section by section.

Skip the manual note-typing

Instead of reconstructing a piece note by note in an editor, start from a transcription that's already 90% there and correct the rest.

Use recordings you made yourself or otherwise have the rights to — your own playing, recordings shared with permission, and public-domain works.

How accurate is it, honestly?

Good enough to be the fastest starting point, and not magic. Clean solo-piano recordings transcribe well: notes, timing, and dynamics land where you played them. Heavy pedal, very dense chords, or noisy phone recordings will produce some extra or merged notes — every piano transcriber on the market has this trade-off, cloud or not.

The difference is what happens next. In a cloud tool, a wrong note means downloading the file and opening yet another editor. In LumaKeys, the piano roll is one click away: fix the note, and keep going. Transcription plus editing in the same app is the whole point.

Questions & answers

Is my audio uploaded anywhere?

No. Transcription runs on-device on your Mac (Apple Silicon). LumaKeys has no account and uploads nothing — your recordings stay on your computer.

How many transcriptions are free?

Five, on the Free tier, so you can properly test it on your own recordings. Pro is $99 one-time and makes transcription unlimited. The free beta is open now, and beta testers lock the $69 founding price.

What audio works best?

Solo piano with a reasonably clean recording. Dense, pedal-heavy passages can come out with extra or merged notes — that's true of every piano transcriber — and in LumaKeys the piano roll is right there to fix them.

Can I edit the transcription?

Yes. Every transcription becomes a normal piece in LumaKeys: open the piano roll, correct notes, adjust timing, split hands, and reshape it however you want.

Can I export the result as a MIDI file?

Yes. You can export the MIDI to use anywhere else, or stay in LumaKeys and export a falling-note video up to 4K/60.

Does it transcribe other instruments or full songs?

It's built for piano. A full band mix or vocals aren't the target — for solo piano recordings, that focus is exactly why it works well.
