Isolate piano or remove piano: keep the notes and the space between them
Choose the Piano output to hear a part more clearly; choose the remaining-song output when you want to play piano along with the rest of the recording. A piano separator estimates audio from a mix. It does not automatically recover an original microphone take, identify every key pressed or produce MIDI. Target-piano tools use a piano-versus-remainder layout, so decide which side you need before downloading.
1. Choose a separation method that includes piano
Choose Piano Extraction — BS Six in the model selector. Expected outputs: Piano · Remaining audio. Start full processing, then play and download the individual tracks. A four-stem result groups instruments outside vocals, drums and bass into Other; it is not a dedicated piano file. Six-stem mode can provide a Piano estimate alongside other groups, but the label does not guarantee that every piano note is correctly assigned. Output classes are defined by the selected unmixing method.
Some products distinguish piano, grand piano and a wider keys group. That is a reminder to read category names closely, not evidence that every such choice exists in uvr online. The current Piano target should not be treated as a promise to separate every electric piano, organ or synthesizer into its own file.
After the full result is ready, compare the difficult passage with the original. Check both the wanted detail and unwanted leakage before choosing a track.
2. Check the piano stem and the piano-reduced backing
- Bass register: is the low piano line still present, or is it confused with the bass instrument?
- Chord center: can you hear the inner notes and changes rather than just the melody on top?
- Attack: does the hammer-like start remain connected to the body of the note?
- Decay: after a chord change, do sustained notes and pedal-like tails remain continuous, or break when the arrangement changes?
This is a suggested listening routine, not a technical measurement of sustain-pedal accuracy. The finished recording may contain reverb that sounds like a long decay, so do not infer exact pedalling from the separated file alone. Return to the original and use musical context to check uncertain details. Focused stem listening can reveal relationships you miss in a full mix, but it remains a listening aid.
For practice, listen for ghost chords that could clash with your own playing. Also check whether removing piano has weakened another sustained instrument or made the arrangement feel empty. A residual track is useful only if it still gives you the cues you need. In a six-stem set, inspect both Piano and Other before deciding where a missing note went. Do not rename Other as Piano and expect an additional separation.
If you want to retain a little original piano as a guide, reduce its player level while practising. To save a custom rehearsal balance, combine the wanted downloads in an audio editor and check the rendered result; playback levels alone are not a new export.
3. Export audio, not a promise of a score
Download your chosen outputs before the displayed expiry and keep common start points. A lossless format, if available to your account, is useful for editing but will not reveal notes that the model missed. For a score, chord chart or MIDI performance, use an appropriate transcription workflow and verify it by ear. If you require exact solo piano for a published arrangement, authorized original stems or a new recording are preferable to treating an AI estimate as ground truth.
4. Frequently asked questions
Can a piano stem become MIDI automatically?
The separation output here is audio. Note transcription is a different task and would need its own tool and verification.
Will the piano option isolate all keyboards?
It should not be assumed to do so. Piano, electric piano, organ and synthesizer can require different categories; check what the selected mode actually offers.
Why does a sustained note sound chopped?
Some decay may be assigned elsewhere or altered during separation. Check the original and other outputs at the same timestamp before using it to learn the part.
Does remove piano mean removing every keyboard?
No. A named piano target does not guarantee removal of organ, electric keys or synth layers. Test the actual sound you need and inspect the residual rather than relying on a broad keyboard label.
