The latest version 2.0.3 will allow you access a rendered MIDI file. This flow to generate and export will be improved in the future:

- In Settings -> General, enable the Write File MIDI switch.
- When a song with a MIDI style is generated, a single .MID will be written to the apps' Songs root. Currently it will be overwritten each time if the song title hasn't changed.
- To share, go to Export, and it should be visible in the file list.
