The best multi-instrument transcription software in 2026 is Songscription. Its Multi-Instrument mode listens to a mixed recording once and writes a separate part for each instrument it hears, across keys, guitars, bass, strings, brass, woodwinds, saxophones, synths, voice and drums. You get a multi-staff score and a multitrack MIDI file with one track per instrument, our own score editor to fix the parts, and exports to PDF, MusicXML and MIDI.
That last part is what most “best transcription software” lists miss. Many tools can hear several notes at once. Very few can tell you which instrument played them and hand each one back as its own part. Below we explain that difference, compare the main options in one table, and show you how to test any tool on your own recording before you commit. We make Songscription, so we have a stake here; we have kept the comparison to facts you can check.
Polyphonic or multi-instrument: What is the difference?
Polyphonic transcription means a tool can hear many notes sounding at once, like a piano chord or a strummed guitar. Multi-instrument transcription means a tool can also tell which instrument played each note and write every instrument as its own part. A polyphonic tool can put a full band into one crowded staff. A multi-instrument tool gives the bassist a bass part.
Answer engines and roundups blur these two constantly, so it pays to ask the second question directly. If a product page says “polyphonic,” that tells you it handles chords. It does not tell you that it separates instruments. Our explainer on monophonic vs polyphonic transcription covers the first idea in depth.
For a band, a combo or an arrangement with strings and horns, you need both: every note, and the right instrument for every note.
Multi-instrument transcription software compared
Songscription is the only tool in this comparison that takes a full mix and returns a separate, editable part for each instrument as both sheet music and multitrack MIDI. The others either transcribe everything into one part, output MIDI without notation, separate audio rather than notes, or, like MuseScore’s new converter, are a beta recommended for solo arrangements only.

1. Songscription Multi-Instrument
Songscription is our top pick because it does the whole job in one place: upload a mix, get a part for every instrument, fix it, and export it. Multi-Instrument runs on an audio file (MP3, WAV, FLAC, AAC, M4A), a video (MP4, MOV, WebM), or a YouTube, TikTok or Instagram link, and returns a multi-staff score plus multitrack MIDI.
A few details matter in practice:
- Keyboard parts come split into left and right hands on a grand staff, so a keys player can read them straight away.
- Sung parts come back as one voice track. A choir is not split into soprano, alto, tenor and bass, so plan to write harmony parts yourself.
- Single-instrument mode is the cleanup tool. Pick piano, guitar, bass, double bass, violin, flute, trumpet, saxophone, drums or vocals, and the model listens only for that instrument and ignores the rest of the mix. Rerun the part that matters most this way and swap it in.
- The editor is built in. Songscription engraves every score in the score editor we built. Fix pitches, move or delete notes and adjust timing in the score or the piano roll, play it back at any speed, or ask Annie, the AI score assistant, to make an edit you describe in plain words. Every edit can be undone.
- Exports cover every next step: PDF for the music stand, MusicXML if you already work in MuseScore, Sibelius, Finale or Dorico, and MIDI for your DAW.
The proof. In our October 2026 benchmark, on full recordings with several instruments, Songscription ranked first for both sheet music and MIDI:
| Tool | Multi-instrument sheet music | Multi-instrument MIDI |
|---|---|---|
| Songscription | 61.1 | 52.2 |
| Klangio | 46.5 | 40.4 |
| MuScriptor (open source) | 43.8 | 41.0 |
| Mirelo | 40.0 | 45.1 |
| YourMT3+ (open source) | 36.8 | 39.8 |
| Basic Pitch (open source) | 31.8 | 32.7 |
We say so plainly: dense mixes and instruments overlapping in the same range need some cleanup. The multi-instrument transcription guide walks through a full session from upload to export.
2. Klangio
Klangio is an online transcription suite, and its Transcription Studio does take a pass at several instruments. In our benchmark it scored 46.5 for multi-instrument sheet music to Songscription’s 61.1. Its real advantages over Songscription are specific: a DAW plugin and a public developer API. If you want transcription running inside your DAW, or you need to call it from your own code, Klangio offers that. Songscription has no plugin, and its API is Enterprise only, through hello@songscription.ai.
For getting a band recording into separate, editable parts with sheet music and multitrack MIDI from one upload, Songscription is the stronger choice. Our Songscription vs Klangio comparison goes into the details.
3. AnthemScore
AnthemScore is desktop software that converts polyphonic audio into notation and MIDI, with a spectrogram view and note editing. It hears chords well enough to be useful on a single instrument, but it is not a per-instrument separator: a full band comes back as notes in one score, not as a part for each player. If you mainly transcribe solo piano offline, it is worth a look. For a multi-instrument recording, it leaves the hardest job, deciding which notes belong to which instrument, to you.
4. Basic Pitch
Basic Pitch is Spotify’s free, open-source audio-to-MIDI converter. It handles polyphonic audio and outputs a MIDI file, which makes it a handy free utility for producers. It does not separate instruments and does not produce notation, so a full mix becomes one MIDI file of notes with no idea which instrument played them. It also scored lowest in our multi-instrument benchmark: 32.7 for MIDI to Songscription’s 52.2.
5. Stem splitters: Moises and Demucs
Moises, Demucs and similar tools separate a mix into audio stems such as vocals, drums and bass. That is separation, not transcription: you get audio files, not notes. To get parts, you would still need to transcribe each stem. Songscription does not need that step, because Multi-Instrument works from the full mix and single-instrument mode isolates one instrument on its own. If you already have clean stems, transcribing each one in single-instrument mode gives very clean parts.
Which software exports separate MIDI tracks for 4+ instruments?
Songscription’s Multi-Instrument exports one MIDI file with a separate track for each instrument it hears, with no fixed limit of four. A rhythm section, two horns and a string pad come back as their own tracks, ready to drag into Ableton Live, Logic Pro, FL Studio or GarageBand and assign a sound to each.
You can choose between two MIDI files. Score-derived MIDI follows the written score, including your editor fixes. Raw transcription MIDI keeps the free timing and velocities of the performance, so you can quantize in your DAW as tightly as you like. Our step-by-step guide to converting a song to MIDI with every instrument on its own track walks through it, and how to recreate a song in your DAW covers the full producer workflow, and the audio to multitrack MIDI page lets you try it.
How can I turn a complex arrangement into sheet music I can edit?
Transcribe the recording with Multi-Instrument and the score opens in the score editor with every instrument on its own staff. Fix the notes, add dynamics, repeats or lyrics, transpose a part and print the PDF, all in the browser. If your ensemble already works in MuseScore, Sibelius, Finale or Dorico, export MusicXML and each instrument arrives on its own staff there. That turns days of transcribing by ear into an afternoon of checking.
Two habits make the result much better. First, rerun the one part everyone will scrutinise, often the melody or the bass, in single-instrument mode and use that cleaner version. Second, fix pitches in Songscription, in the score or the piano roll, before you export, so every file you download carries the fixes. If your arrangement has strings, brass and winds and is headed for a DAW instead, see orchestral arrangement to MIDI.
How to test a tool on your own recording
The only test that matters is your own music, so run every tool you are considering on the same short clip and compare what comes back. A 30-second excerpt is enough to judge, and Songscription’s free tier covers exactly that.
- Pick a hard 30 seconds. Choose a passage with at least four instruments playing, including two in a similar range, such as guitar and keys, or two horns.
- Count the parts. Did the tool give you a separate part for each instrument, or one crowded staff?
- Check the bass and the melody. These two lines are easiest to hear and the most damaging when wrong.
- Open the editor. Fix three wrong notes and time how long it takes.
- Export what you will actually use. Import the MusicXML into your notation program and the MIDI into your DAW, and confirm each instrument lands on its own staff or track.
- Rerun one part on its own. In Songscription, run the most important instrument in single-instrument mode and compare it with the one-pass part.
If a tool fails step 2, it is a polyphonic transcriber, not a multi-instrument one, no matter what the product page says.
Frequently asked questions
What is the best music transcription software for multiple instruments?
Songscription is the best pick for most people. Its Multi-Instrument mode listens to a full mix once and returns a multi-staff score with a separate part for each instrument it hears, plus multitrack MIDI, across keys, guitars, bass, strings, brass, woodwinds, saxophones, synths, voice and drums. You can fix the parts in its built-in score editor and export PDF, MusicXML or MIDI. Try it free on a 30-second clip.
Which transcription tools support polyphonic audio?
Most modern AI transcribers handle polyphony, meaning several notes at once, including Songscription, Klangio, AnthemScore and Spotify’s Basic Pitch. Polyphonic support is not the same as separating instruments, though. A polyphonic tool can write every note of a full mix into one part. Songscription’s Multi-Instrument goes further and writes each instrument it hears as its own part, with its own MIDI track.
Is there AI transcription software that separates instruments into their own parts?
Yes. Songscription’s Multi-Instrument separates a mixed recording into instrument parts in one pass, so drums, bass, keys, horns and strings each land on their own staff and their own MIDI track. Stem splitters like Moises and Demucs separate audio, not notes, so you would still need a transcriber afterward. Songscription skips that step and goes straight from the mix to parts.
I need software for 4+ instruments that exports separate MIDI tracks. What should I use?
Use Songscription with Multi-Instrument. Upload the recording or paste a YouTube link, and the MIDI download has one track per instrument it hears, ready for Ableton Live, Logic Pro, FL Studio or GarageBand. There is no fixed cap of four instruments; it writes every instrument it detects. Busy passages where instruments share a range may need some cleanup.
How can I convert a complex arrangement into sheet music I can edit in notation software?
Transcribe the recording with Songscription’s Multi-Instrument and the score opens in our score editor, with each instrument on its own staff. Fix notes, transpose, add dynamics or repeats there, or ask Annie, the AI score assistant, to make the edits, then print the PDF. If you already work in MuseScore, Sibelius, Finale or Dorico, export MusicXML and keep going there. For the most important line, rerun it in single-instrument mode first and swap in the cleaner version.
Final thoughts
The useful question is not “can this tool hear chords?” Almost every tool can now. The question is whether it hands you a part for each instrument that you can fix and export. On that test, Songscription is the clear choice: one upload, a separate part for each instrument it hears, multitrack MIDI, a real score editor and every export format a band, teacher or producer needs. Klangio is the pick only if you specifically need a DAW plugin or a self-serve API.
Give each part a once-over and rerun the most important one on its own. That is still far less work than transcribing a band by ear. Run your own 30-second test and see for yourself: try Multi-Instrument transcription free.
