What is MIDI? MIDI stands for Musical Instrument Digital Interface. MIDI allows multiple hardware and software electronic instruments, performance controllers, computers and other related devices to communicate with each other over a connected network. It is used to translate performance or control related events into equivalent digital messages and then transmits these messages to the other MIDI devices where they can be used to control sound generators and other performances/control parameters. So it acts almost like a messenger/translator to other devices so that they can work together.
MIDI data can be recorded into a hardware device or software program, where it can be edited and transmitted to electronic instruments or other devices to create music or control any number of parameters in a post performance setting. MIDI can also be used to vary the performance and control parameters of electronic instruments, recording devices, control devices and signal processors in the studio on the road or on stage.
MIDI Cable:
The cable consists of a shielded, twisted pair of conductor wires that has a male 5-pin DIN plug located at each of its ends.
* Pin 1 is not used in most cases. Although it can be used to provide the V (ground return) of a MIDI phantom power supply.
* Pin 2 is connected to the shield or ground cable, which protects the signal from radio and electromagnetic interference.
* Pin 3 is also not used in most cases. Although it can be used to provide V+ (+9 to +15V) of a MIDI phantom power supply.
* Pin 4 is a MIDI data line
* Pin 5 is also a MIDI data line.
There are many different wants to use MIDI and it can do lots of different things. I feel at this chapter is a chapter I will need to relook at in the near future. There is just so much information that needs to be absorbed that won't sink in with just one read. Having this information known would be very helpful because it is very useful being able to do so many things and to just explore and see what kind of sounds can be created.
