Workflow

Three steps to MIDI.

01
Import your piano recording

Drop in any WAV, MP3, or FLAC audio file of piano playing. Single file or batch-import a whole folder at once.

02
AI processes entirely on your device

Melodfy uses the Piano Transcription model by ByteDance, running via ONNX locally. Every note, timing, and velocity captured — your audio never leaves your machine.

03
Export the MIDI file

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