The creator of this installation is the Swedish designer Axel Bluhme. The inventor developed his musical apparatus as a student, while studying at the Royal College of Art in London. In fact, the XOXX Composer is nothing more than a music box, only in a modern way. However, it would be more correct to compare the installation with a digital mixing console in a new format. To “sound” the instrument, magnetic balls are used, which are attached to one of sixteen clearly marked places on eight vertically rotating disks. At the bottom of the device there is a sensor that fixes the position of the balls on the wheel and, depending on it, this or that sound is reproduced. Using the software, the user sets a tone for each disk or assigns the sound of a specific musical instrument. There are sliders for volume and key. For operation, the XOXX Composer is connected to the computer via a MIDI connector. While the unusual installation is not for sale anywhere, but its creator in the near future plans to go with his product to one of the popular crowdfunding venues.
