Music Box Composer

Music Box Composer is a musical composing tool based on the physical 15, 20 and 30 note paper strip music boxes. It’s notes are sampled from actual music boxes and you can play and share your creations without requiring the physical music boxes at all, but it is designed as a direct aid to creating the punch strips used for the Mechanical Music Boxes.

– Share your compositions with others via Facebook, Twitter and Email

– Sounds sampled from physical Music Box for added reality

The physical Music Boxes with the paper punch strips and are great fun – what was missing was an easy way to preview either transpositions or original creations. This app fills that gap.

Designed to aid composing your own music prior to punching the paper strips for Music Boxes, this allows you to compose, preview, play, save and share your creations (via Facebook, Twitter, Email, or iTunes file transfer/Android local storage). Simulates 15, 20 and 30 note music boxes.
