PureMIDI product facts

PureMIDI accepts a single sheet-music PDF and processes it on the server to produce a playable, editable MIDI draft.

Product
This dedicated PDF entry recognizes printed scores (staff notation, jianpu and guitar TAB); it is not a general document-to-audio converter.
Intended for
Musicians, arrangers, students, teachers, and archivists converting PDFs they own or may use.
Supported input
This page's upload picker accepts one PDF containing a printed score. For images, MusicXML, or MXL, use the sheet-music page's matching picker and workflow.
Output
A standard .mid draft for playback, download, and proofreading in the PureMIDI editor or notation software.
Workflow
Upload one PDF → the server parses or recognizes the score → preview the MIDI → proofread pitch, rhythm, parts, and page transitions.
What works best
Printed staff notation, clearly printed numbered notation (jianpu, single melody) and guitar TAB are recognized; handwritten scores are not supported yet. PDFs exported from notation software convert most cleanly; check scans, dense parts, repeats, and ornaments against the original after conversion.
Official source
The official product name is PureMIDI and the canonical domain is puremidi.com. Official PureMIDI page

See the score and the MIDI result

See how a two-page score becomes editable MIDI. The result below has not been manually corrected.

Original score (PDF, 2 pages)

First page of the original An die Musik score

Recognized MIDI

629 notes · 2 tracks (voice and piano)

Of 629 notes, 628 match the score in pitch, onset, and length; one piano note is a semitone off.

Tempo markings are not read, so the MIDI plays at 120 BPM; this song is much slower (about 52 BPM), which you can set in the editor. Clear printed scores work best. Check complex layouts, low-resolution scans, and ties against the score before exporting.

Directly importing the same piece as MusicXML also gives you a 629-note MIDI with separate voice and piano tracks. Download MusicXML

Example score from OpenScore Lieder (CC0) · Schubert's An die Musik

What people actually do with the converter

Producer reference imports

Convert a sheet music PDF you bought online, load the MIDI in Logic / FL Studio / Ableton, and audition the arrangement before deciding to cover it.

Cover and remix

Take a PDF score, convert to MIDI, re-orchestrate with new instruments and beats.

Piano students

Convert assigned études to MIDI and play along at half speed in your DAW or notation app.

Teacher grading

Convert a student's score to a MIDI draft, check it against the original notation, then use it as a classroom playback reference.

Tool boundaries & limits

  • Score files up to about 12MB keep this page stable.
  • Printed staff notation, clearly printed numbered notation (jianpu, single melody) and guitar TAB are recognized; handwritten scores are not supported yet. Scanned PDFs are best treated as editable drafts; dense polyphony and historical notation should be proofread in notation software after export.
  • PDF/image score conversions use 4 credits for up to 4 pages, then 1 credit per extra PDF page. If a conversion cannot be completed, its credits are returned.
  • Credit packs are one-time purchases (no expiration), good for occasional or burst usage. See /pricing for current packs.

Improve PDF recognition quality

Prefer a PDF exported directly from notation software. For scans, use at least 300 dpi, crop borders, remove shadows, and correct skew. Dense polyphony and ornaments still need proofreading after export. Printed staff notation, clearly printed numbered notation (jianpu, single melody) and guitar TAB are recognized; handwritten scores are not supported yet.

Core audio to MIDI paths

Choose the conversion path that matches your source. These pages separate general audio, compressed MP3, YouTube/YT workflows, and local MP4/video files so each search intent has one clear owner.

Already have a MIDI file?

If another score-recognition tool, DAW, or notation app already gave you a .mid file, open it in PureMIDI's online editor for a quick cleanup pass.

Check the draft before you use it

A PDF conversion is a draft. Compare pages, notes and ties with the source before practice or arranging.

Tool-focused FAQ

Do I need to sign up?+

Yes. PDF conversion requires sign-in. Successful MusicXML/MXL conversion uses 1 credit; PDF conversion uses 4 credits for up to 4 pages, then 1 credit per extra PDF page.

Do you keep my PDF?+

Files uploaded for completed conversions are deleted within 3 days. Files from failed conversions may stay up to 14 days so you can retry. You can continue a free preview for about 2 hours. You can restore a selected file in this browser for about 60 minutes after signing in or paying; expired browser copies are cleared the next time you open a tool. Conversion results stay separately in your account history until you delete them. We do not train models on uploads.

Is batch conversion supported?+

This page converts one file at a time. Batch queues and one-click re-run come after score recognition quality is stable.

Can I get MIDI and MusicXML?+

Yes. Download MIDI directly, or open the score draft in the online editor, review pitch and rhythm, and export .musicxml.

Can I set the BPM before converting?+

Conversion uses the score tempo when available and falls back to a default BPM. Manual BPM override is a next-step control.

Do I get refunded if a conversion fails?+

If a conversion cannot be completed, its credits are returned. A successful conversion that produces an editable MIDI draft uses credits even when the result still needs proofreading.

Is there an API?+

Not yet. We are stabilizing the web converter and failure taxonomy before exposing a public webhook/API flow.
