Frequently Asked Questions
What do I get after processing?
Each job returns downloadable files for the output you selected. Depending on the task, that can include an editable Guitar Tab file, with Guitar and Backing track audio added for full-mix Tab jobs; stem audio packs; DAW-ready MIDI; and PDF score drafts + editable MusicXML.
What audio formats are supported?
MP3, WAV, FLAC, M4A/AAC, OGG, AIFF, and most common formats. If something needs conversion, the app handles it automatically.
How is processing handled?
Jobs run through Music Demixer's secure cloud service to generate your outputs quickly and reliably. You upload once, then download the files for your workflow.
Is there a free plan?
Start with one Free Preview job, including downloads from a representative segment. Buy a 5-job Pack or subscribe to Pro to process more jobs and download full-length results.
How do I convert audio to MIDI?
Upload the recording, choose the instrument you want as MIDI or Multi-Track, and run the job. You download Original Timing MIDI and Beat-Aligned MIDI. MP3, WAV, FLAC, M4A, and other common audio formats work.
Can I convert a full band recording to MIDI?
Yes. Choose one instrument and Music Demixer separates that part before transcription, or choose Multi-Track for MIDI of several instruments. Single-part MIDI works best from a stem or solo recording, and full-mix results need more cleanup.
Which instruments convert most accurately?
Piano and drums give the most detailed MIDI. Bass, vocals, guitar, and Other return editable note drafts. Vibrato, distortion, and overlapping notes usually need correction after import.
Do I need to install anything?
No. Music Demixer is a web app with secure cloud processing. Upload in the web app and download the MIDI files when the job finishes.
Can I try it for free?
Yes. Your free preview is one job, and you can download a representative segment up to 30 seconds with no card required. A 5-job Pack or Pro unlocks full-length downloads.
Turn Recordings into MIDI You Can Edit
Convert an audio recording into MIDI notes you can edit, re-voice with another instrument, or build an arrangement around. Upload in the web app with no install and use secure cloud processing.
Which recordings convert best
Piano and drums have the most specialized transcription and give the most detailed MIDI. Bass, vocals, guitar, and Other return editable note drafts. A single part from a stem or solo recording converts more cleanly than a full band mix. From a full mix, choose the instrument you want and Music Demixer separates that part first.
Whole arrangements
To convert every instrument in a song, choose Multi-Track MIDI. It returns MIDI for multiple instruments plus MusicXML and PDF score drafts. Expect more cleanup than a single-part conversion.
Bring it into your DAW
Import the MIDI into Ableton Live, Logic Pro, FL Studio, GarageBand, Cubase, REAPER, or another DAW. Timing, note lengths, and octaves can need adjustment. For a quick single-part draft see the MIDI Extractor, or compare every option on MP3 to MIDI.
