Convert piano recordings or other musical audio and video to editable MIDI. Choose piano transcription or compare four general MIDI models, preview and download. Convert piano-focused audio or video to MIDI; convert common audio formats; separate vocals and accompaniment, drums, bass, guitar, piano, synthesizers, bowed strings or wind instruments into target and remaining tracks; or reduce background noise in speech, interviews and podcasts.

Choose the output you need

General MIDI offers four selectable models: MeluMimi Lyra, Aria, Muse and Opus, each with an independent result. The piano tool returns standard MIDI with notes, timing, velocity and optional CC64 sustain. Format conversion returns a converted audio file. Stem separation returns synchronized target and remaining tracks. Denoising offers a first-60-second listening preview and a paid full-length WAV result after confirmation.
