The MIDI IN inlet is used so one piece of equipment that receives information on its MIDI IN inlet will be controlled by another piece of equipment. MIDI OUT sends information from one piece of equipment to another piece of MIDI equipment.
 * How MIDI messages work**

The MIDI THRU outlet sends a copy of the information that is received on its MIDI IN inlet. A MIDI THRU box is a way of connecting many MIDI devices together and have each of them //Fig 2 MIDI In, Out and Thru//

MIDI hardware can be defined as any kind of the equipment used to generate MIDI or control MIDI. There is an endless list of MIDI hardware ranging from simple keyboard controllers to highly sophisticated synthesizers. Nearly all MIDI equipment that is created has the following three connections.
 * MIDI Hardware**

A DIN cable is the most widely used cable for using MIDI devices. This works the same way as an XLR cable a send and return line encased in a screen to help reduce noise.
 * DIN, USB and IEEE1394 Cables **

 * MIDI module**

An example of a MIDI module is a device that needs to have a controller attached to it for the module to operate; a synthesizer would be an example. A MIDI synthesizer is a device that generates sound. It basically does the same job as an analogue synthesizer but by digital means, with a midi controller and a simple synthesizer a wide range of sounds can be generated from a grand piano to a gunshot.
