PureMIDI
PureMIDI is a browser-based MIDI converter that turns audio recordings and sheet music into editable .mid drafts for any DAW. Producers, musicians, teachers, and students upload MP3, WAV, or score PDFs, pick whether the file is one melody or a full song, and download standard MIDI they can refine in Logic, Ableton, FL Studio, Cubase, and other major tools.
Two production routes cover different jobs. The clear-melody path costs 1 credit and targets solo vocals, guitar riffs, and isolated lines. The full-song path costs 6 to 15 credits by length and drafts multi-track MIDI from mixed arrangements with drums, chords, and multiple instruments.
Beyond audio, PureMIDI also converts sheet music PDFs, MusicXML, and score images through beta score recognition, plus local MP4 and MOV uploads for video-to-MIDI. Eligible new accounts receive 2 credits, uploads accept files up to 25 MB, and successful conversion sources are deleted within 3 days. The site states it never trains models on user content.
Built for real production workflows: transcribing hooks into arrangement sketches, converting student recordings for grading, and turning assigned scores into playable MIDI for ear training. No plug-ins or DAW install is required to start.

Yes. PureMIDI offers a free 30-second audio preview before sign-in on eligible uploads, and eligible new accounts receive 2 credits. After that, you buy one-time credit packs that never expire. Clear-melody conversions cost 1 credit; full songs cost 6 to 15 credits by length.
What audio formats does PureMIDI support?
PureMIDI accepts MP3, WAV, M4A, FLAC, OGG, WEBM, AAC, and AIFF for audio conversion. Maximum upload size is 25 MB for both free preview and full conversion after sign-in. Lossless WAV and FLAC generally produce the most accurate MIDI drafts.
Will PureMIDI MIDI files work in my DAW?
Yes. PureMIDI exports standard .mid files that open in Logic Pro, Ableton Live, FL Studio, Cubase, Reaper, GarageBand, Studio One, Pro Tools, MuseScore, Sibelius, Dorico, and other major DAW or notation tools.
What is the difference between clear melody and full song mode?
PureMIDI asks whether your audio is one melody or instrument or a full song with multiple parts. The clear-melody route costs 1 credit and works best on solo vocals, guitar, and isolated lines. The full-song route costs 6 to 15 credits and drafts multi-track MIDI from mixed arrangements.
Does PureMIDI keep my uploaded audio?
PureMIDI deletes successful conversion sources within 3 days and may retain failed sources for up to 14 days for recovery and support. Free-preview records clear after about 2 hours. The site states it never uses your audio or scores to train models.
Can PureMIDI convert sheet music PDFs to MIDI?
Yes, in beta. PureMIDI converts PDF sheet music, MusicXML, MXL, and PNG, JPG, or WebP score images into MIDI via score recognition. Standard staff notation for piano, vocals, strings, and ensemble scores is supported.
How do I contact PureMIDI support?
