Frequently Asked Questions
What instruments work best?
Monophonic sources (single melody lines, bass) convert most accurately. Polyphonic content (chords, full mixes) produces approximate results — review the piano roll before exporting.
Can I convert a full mix to MIDI?
Results will be approximate for full mixes. For best results, separate stems first using the Vocal Remover, then convert individual stems.
Is my audio uploaded to a server?
No. All processing runs directly on your device using your own GPU or CPU. Your files never leave your machine — not even temporarily.
