Which model do I need for piano?

6stem. It is the only one that treats piano as its own part — in 4stem the piano is folded into "other".

What about electric piano or organ?

They land in the same "piano" slot. Where the timbre is close to a synth or a guitar they can bleed into "other" — results vary by track.

Almost no piano came out.

The piano on that record probably does not sound like a piano to the model. The usual causes are heavy effects, a patch voiced toward synth, and a part sitting quietly behind the arrangement. Listen to the other track — the piano is often in there, mixed with everything else, which means it cannot be isolated on this pass.

Does it work on classical piano?

On solo piano recordings there is nothing to separate; the original already is the piano, at better quality than any separation would give you. Where it earns its keep is piano within an ensemble — concertos, song accompaniment. Even then, separating from an orchestra falls outside what the model was trained on, so expect less than you would get from popular music.

Can I practise over a mix with the piano removed?

Yes. After separating, turn Solo off and mute only the piano. Choose “Export”, then “Mix”. Bear in mind that piano bleeds into the other parts more than most, so muting it may still leave a trace. Do not assume it vanishes completely — listen before you export.

Is it really free? Do I need to sign up?

It’s completely free with no account needed. Just open the page and pick a file.

Is the song I choose sent anywhere?

No. All separation happens entirely inside your browser.

Which file formats are supported?

MP3, WAV, M4A, AAC, FLAC and OGG, plus the audio track of video files.

One mix, separated into its individual parts

Piano extraction isolates the piano parts — for working out a chord progression, transcribing a line, practising the part yourself, or lifting material for a remix.

Piano is among the hardest of the six. Its register is wide and overlaps guitar, synths and strings, so those can bleed in — and parts of the piano can stay behind in "other". Electric piano and organ are handled in the same slot. It is genuinely useful for hearing a progression; check the result before using it as standalone material.

There is a second reason it is hard: one instrument covers the whole range at once. The left hand shares territory with the bass, the right-hand voicings share it with guitar and synths. Every other instrument owns a band, which gives the model a usable clue; piano does not. The visible result is that the low notes of a single performance can end up on a different track from the high ones.

When the piano refuses to come out cleanly and all you wanted was the chords, there is another way in. The key, BPM and tuning analyser identifies the key of the track, and knowing the key narrows the plausible chords down sharply. Used alongside whatever the separation did give you, it settles progressions that neither would on its own.

Highlights

6stem separates piano: Splits into vocals, drums, bass, guitar, piano and other, with piano exportable on its own.
Piano-less mix in the same run: Mute the piano and export the mix for a track to play over yourself.
Chords you can follow: With the rest of the band out of the way, the voicing and the left hand are much easier to hear.

Three simple steps

Open a file
Choose an MP3, WAV, M4A, FLAC or video with “Open file”, or drag it into the workbench.
Check settings and separate
Piano comes out on its own only with 6stem. In 4stem it is folded into 'other'. 6stem needs a lot of memory, so it is not offered on phones — run it on a desktop. Check the settings selected for this task, then press “Separate”.
Listen and export
Use Solo and Mute to listen to the parts you need, then choose “Export” to save WAV or MP3.

Check how the piano separates in the demo

Open the prepared six-part separation of “Shining Star” by MaouDamashii / Koichi Morita. On the audio separation page, choose “Open prepared demo”, enable Solo on PIANO, and play. Listen to OTHER and GUITAR individually too, to check whether keyboard notes remain in another part.

The demo uses previously separated audio. Before processing your recording, listen for missing chord notes and bleed from other instruments. It does not provide a perfectly isolated piano recording or automatic sheet-music transcription.
