AI Piano to MIDI · Free · Open Source
your piano recordings, as MIDI.
Play piano. Record it. Melodfy converts the audio to an accurate, editable MIDI file using AI — entirely on your device. No cloud. No account. No waiting.
Drop in any WAV, MP3, or FLAC audio file of piano playing. Single file or batch-import a whole folder at once.

Get a clean MIDI file ready to open in FL Studio, Ableton, Logic, GarageBand, or any DAW. Edit, arrange, and build from there.
