Audio-to-MIDI (also referred to as Meloddyne Studio) is a transcription model from Mirelo that converts audio into editable MIDI and MusicXML. According to a YouTube review, it can take a full song with vocals and split it into separate MIDI tracks per instrument. The reviewer demoed it in a free online studio and estimated roughly 80% accuracy.
Mirelo's site lists Audio-to-MIDI among its audio tools, alongside a video-to-sound-effects editor, an MCP server and an API. Recent news items on the site mention that it now runs inside a DAW, that it transcribes lyrics timed to the notes, and that a browser-based "Audio-to-MIDI Pro" is used by riffle.
The reviewer said the model is open source in small, medium and large variants (up to 1.4B parameters) under a non-commercial license. The provided pages do not confirm this, and no repository or Hugging Face link was found, so the release details are unverified. Pricing for the Audio-to-MIDI tool specifically was not available in the provided text; Mirelo's general product advertises a free plan with no credit card.
