While building PureMIDI, I kept running into an overly broad label: audio to MIDI. A clean solo stem and a dense full mix are different transcription problems.
For a solo or isolated stem, note and onset accuracy matter most. For a full mix, instrument separation and cleanup time matter more. That is why PureMIDI uses Quick Melody for clean sources and Pro Song for editable multi-track drafts.
I m curious how producers evaluate these tools: note accuracy, separation, or minutes of manual cleanup? If you have a useful 30 60 second test case, what kind of source should we benchmark next?
PureMIDI turns audio and sheet music into editable MIDI drafts for your DAW or notation app. Use Quick Melody for clean solos and isolated stems, or Pro Song for multi-track drafts from full mixes. It also supports MP3, WAV, video, PDF/image scores, MusicXML/MXL, and rights-cleared YouTube workflows. Dense arrangements still need review, so results are positioned as an editable starting point—not finished notation.
