If yes, does it generate MIDI an audio, separate tracks?

Regards.

Yes it adds them to the Extra tracks but the midi file is in the SavedTracks folder.
I waited an hour for it to create them BUT lol the Harmonies window was hidden behind the DAW.

Hi Jorge, the plugin can generate audio harmonies from an audio track, or MIDI harmonies from a MIDI melody, however the plugin does not support frozen tracks so it cannot load previously generated harmonies. Hope this helps!
