Universal serial bus musical instrument digital interface hardware

Abstract

This article explores possibilities of coordination between computer made music and other stage devices. Purpose of develop was to create simple universal hardware for using in music software communicating via MIDI protocol and USB. This hardware is meaning for professional music live performance. At the input this device communicates via MIDI and USB protocols. At the output is tension. Its value is managing by pulse-width modulation. This modulation value is given to value of the third byte in MIDI message. This value is sound power of control note. There is device is connected as one of USB interfaces at the input. There is device is connected to power transformation device on output. There are artificial smokes, lights and fountains are connected to power transformation device as ending equipment.
