PureMIDI

PureMIDI is an AI-powered audio to MIDI converter that turns uploaded recordings into editable MIDI drafts. It is built for cases where a clear melody, backing part, or fuller mix needs to be transcribed into MIDI for later editing in a DAW. The service runs in the browser and produces standard .mid files.

Its transcription engine detects pitch, timing, and velocity. The page describes two conversion modes: Quick Melody for one clear part such as a solo vocal, lead melody, riff, bass, or instrument stem, and Pro Song for full songs, backing tracks, chords, polyphonic piano, and mixed audio. Quick Melody uses 1 credit, while Pro Song uses 6–15 credits depending on length. The site also shows MIDI previews and examples generated through the same conversion paths, including single-part and full-song drafts. It notes that the output is editable MIDI notes and that users may need to lightly quantize and clean up dynamics in their DAW.

Supported uploads include MP3, WAV, M4A, FLAC, OGG, WEBM, and AAC, with a maximum file size of 12 MB. The page says that audio exported from a video the user owns or is licensed to use can also be uploaded. The resulting .mid files are described as compatible with every major DAW, and the page names Logic Pro, Ableton Live, FL Studio, Cubase, Reaper, and GarageBand. It also presents use cases for transcription and covers, DAW production sketches, music education, and remix starters. The site includes notes on accuracy, recommending clean monophonic vocals or solo instruments for best results.

PureMIDI offers 2 free trial credits on signup. It states that there is no subscription. The page also includes an Upgrade to Pro option for longer conversions and more credits.
