Family Composer — About this game
``Family Composer'' is music production software for the Famicom Disk System that allows you to enjoy composing and playing music using the Famicom controller. In the COMPOSER menu, you can set the accompaniment genre, tempo, tone, etc., and choose between easily layering melodies using real-time input, and arranging notes and chords for each beat. Because the system produces sounds that match the accompaniment, it's easy to put together a song even if you play freely, and you can even try out detailed compositions by specifying chord progressions and special symbols. In addition to saving the songs you create to disk and recalling them later with LOAD, you can also use GRAPHIC PLAYER to enjoy playing and adjusting the tempo while watching the seaside animation.
