Welcome to the world of MIDI controllers. MIDI, short for Musical Instrument Digital Interface, is a system that allows instruments such as synthesizers and drum machines to communicate with each other, and also with other devices such as computers and effects processors. MIDI can be used a number of ways: triggering a note or sequence on a MIDI-capable software, turning functions on and off within a computer program, changing presets on a multi-effects processor, and countless other applications. Because of this, there are a wide range of MIDI controllers available. While the form and layout of a MIDI controller is dictated by its intended use, all have one thing in common: they are all able to interact with any MIDI-equipped device. Our MIDI controllers here allow someone in a studio setting to be able to play digital instruments or VST's within MIDI capable software. If you're a beat maker or producer and want to be able to play the notes or pads to make the sound happens, that's where these MIDI USB controllers become very useful.
