Only those soundfonts, midi musics are use which had permissive license. However many licenses were hard to find. Musics are remake/remixes and may resemble an OST. In that case please let me know if you have problem with distribution of the musics. I will remove them :/
The assets used were used with the purpose of giving a demo of audio produced by this app.
