About PureMIDI

PureMIDI is an AI-powered MIDI conversion platform that helps music producers, performers, teachers, and students turn audio recordings and sheet music into editable MIDI files. The service detects pitch and timing from audio sources and converts them into standard MIDI drafts that can be imported into any major DAW or notation software.

The platform supports multiple input formats including MP3, WAV, M4A, FLAC, OGG, WEBM, AAC, AIFF audio files, as well as MP4, MOV, WebM, and M4V videos. Sheet music can be converted from PDF, MusicXML, MXL files, and photographed or scanned score images. Output is always a standard .mid file compatible with Logic Pro, Ableton Live, FL Studio, Cubase, Reaper, GarageBand, Studio One, Pro Tools, MuseScore, Sibelius, and Dorico.

PureMIDI operates through a browser-based interface with no plugins or desktop application required. Users can preview eligible audio uploads for up to 30 seconds free, then purchase one-time credit packs for complete conversions. The platform never uses user uploads to train models and deletes successful conversion source files within 3 days.

FAQ

What is PureMIDI?

PureMIDI is an AI-powered MIDI conversion toolkit built for audio-to-MIDI, PDF-to-MIDI, and practical music transcription workflows where the goal is an editable .mid file, not a finished audio master.

How does audio-to-MIDI conversion work?

PureMIDI analyzes pitch, rhythm, and timing from the source audio, then maps detected notes into a standard MIDI file. Results are intended as an editable starting point, so musicians should review quantization, note lengths, and voicings inside a DAW.

How does the credit system work?

PureMIDI uses credits for complete conversions. You can hear a free 30-second preview before signing in, then buy one-time credit packs when you want the full result.

What input and output formats are supported?

Audio formats include MP3, WAV, M4A, FLAC, OGG, WEBM, AAC, and AIFF with standard .mid output. Video formats include MP4, MOV, WebM, and M4V. Sheet music supports PDF, score images, MusicXML, and MXL. MIDI files can be imported into Ableton Live, Logic Pro, FL Studio, Cubase, GarageBand, and most notation tools.

Does PureMIDI keep my audio files or sheet music?

PureMIDI never trains on user uploads. Successful-conversion source files are deleted within 3 days; failed-conversion sources may be retained for up to 14 days for recovery and support.
