MIDI Connector PinOut Diagram(In, Out, Male, Female)

A MIDI connector is a type of cable that allows electronic musical instruments and equipment to communicate with each other. It enables devices like keyboards, synthesizers, and computers to send and receive musical information, such as notes, rhythms, and control commands. The MIDI connector acts as a link that allows different devices to connect and exchange data, which is then used to produce sounds or control various parameters of the musical setup. The 5-pin MIDI connector is the most widely used MIDI connector and consists of a circular connector with five pins. It is the standard connector for MIDI devices and is used for transmitting MIDI data between devices. The pin configuration and functions of the 5-pin MIDI connector are consistent regardless of whether it is a male or female connector. 

Here is the PinOut diagram of 5-pin MIDI connectors( Male and Female)

As you see in the above PinOut diagram the 5-pin MIDI connector has the following pins,

Pin	Function	Description
1	N/C	Not typically used in MIDI connections and is often left unconnected.
2	Shield/Earth	Used for electrical grounding and provides a reference potential for the MIDI signal.
3	N/C	Generally, it is left unconnected for some times it is used for additional data lines
4	Power	Used to supply power to certain MIDI devices that require it (not required for standard MIDI communication).
5	Data	Responsible for transmission of MIDI data

MIDI In (Current Sink): The MIDI IN port of a device acts as a current sink. It receives the MIDI data from the transmitting device's MIDI OUT port. A current sink is designed to accept and consume the current provided by the transmitting device. It essentially reads the MIDI data and processes it accordingly within the receiving device.

MIDI Out (Current Source): The MIDI Out port of a device functions as a current source. It generates and sends the MIDI data to the receiving device's MIDI In port. A current source supplies the necessary current required for the MIDI data transmission. It produces the electrical current that carries the MIDI data to the connected device.

Remember that In MIDI connections, the terms "current sink" and "current source" are used to describe the behavior of the MIDI input (MIDI In) and output (MIDI Out) ports of devices, respectively. But the functions of each pin are the same.
