The first music box factory opened in 1815, and with it came a unique way to enjoy music. Now you can use the same principles to create your own masterpieces with the XOXX Composer Digital Music Box. This novel MIDI compatible machine uses a series of eight rotating discs for control. Simply add a magnet to a disc at one of the 16 steps to trigger the sound you've chosen via the included software, and control the pitch and volume via the knobs and sliders below. There's also a slider on the side with an LED readout for controlling the BPM, and a large sample library lets you get up and running quickly right out of the box.
