Pile of booksMany of the hymns in the Seventh-Day Adventist hymn book are included in the standard repertoire of the Hymnal Plus. An optional upgrade to add the 234 missing tunes and provide complete coverage of the book is now available. Due to copyright restrictions, this upgrade does NOT enable selection of hymns by SDA book number. Instead, the upgrade is supplied with additional loose Master Index pages to insert into the HT-300US Master Index book.
