MIDI Controllers

A MIDI Controller or MIDI Control Surface is a digital device that transmits MIDI data to other devices capable of receiving it.

The most common use of a MIDI Controller is to control software instruments used on a computer. Other uses include controlling DAW software or external hardware by sending MIDI CC control messages. this is particularly useful when automating tracks within your DAW, or for controlling the transport controls. Today, nearly all controllers transmit and connect directly via USB.
