Create your own Music Box music, and easily share your compositions with others.

Designed to aid composing your own music prior to punching the paper strips for Music Boxes, MBC allows you to compose, preview, play, save and share your creations via Email or iTunes file transfer.

A small but growing library of Music Box Strips can be viewed here, via webplayer or loading into MBC on device:

Demo of composing, printing, punching an playing:

- Supports 15, 20, 30 and 33 note music boxes.
- Share your compositions with others via Email.
- Multiple undo
- Disable Notes for temporary changes
- Ripple edits
- Save and Load (access the save location via iTunes File Sharing)
- Sounds sampled from physical Music Boxes
- Save strip to PDF/JPG file.

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 aims to fill that gap but it's also a fun music creation tool in it's own right.

Rated as a Killer App by Apps4iDevice.

Note that there is a desktop version of MBC available from the Mac App Store, as well as desktop versions for other OS's from the Jellybiscuits site.

Used to work fine but now no sound

This app used to be really cool for helping transfer comps onto paper strips and not sure what happened but now NO SOUND. Checked silent mode on side of phone and settings to make sure sound was enabled across the board and still no sound. Also PLAY button doesn’t work anymore. Dev should update especially since there’s been an increase in hobbies/art since pandemic.

UPDATE: Reinstalled and toggled sound. Working again. Dev should still consider updating to avoid confusion with new downloads. Can see potential purchasers getting frustrated trying to troubleshoot issues that should not be there in 2022. Good app. Better with minor fixes.

Needs improvements

This is a great app if your making a quick tune, but I want to do a full song and so this app is very restrictive, it’s not long enough, there is a plus and a minus symbol at the end making it seem like I should be able to make it longer but it doesn’t seem to work also the tutorial doesn’t mention all of the buttons so I still don’t know what half of them do. On top of that there is one point where it stops when I’m trying to play it and I have to manually move it past and resume it then, and another point where it refuses to do anything past it

Here's the fix if you have no sound!

Turn off your mute/ringer switch on the side of your phone. That fixes it.

Great app, really wish their was a user guide. The tutorial is very small/basic and the program is difficult to learn.
