MIDI

MIDI (/ˈmɪdi/; short for Musical Instrument Digital Interface) is a technical standard that describes a protocol, digital interface and connectors and allows a wide variety of electronic musical instruments, computers and other related devices to connect and communicate with one another. A single MIDI link can carry up to sixteen channels of information, each of which can be routed to a separate device.

MIDI carries event messages that specify notation, pitch and velocity, control signals for parameters such as volume, vibrato, audio panning, cues, and clock signals that set and synchronize tempo between multiple devices. These messages are sent via a MIDI cable to other devices where they control sound generation and other features. This data can also be recorded into a hardware or software device called a sequencer, which can be used to edit the data and to play it back at a later time.

MIDI technology was standardized in 1983 by a panel of music industry representatives, and is maintained by the MIDI Manufacturers Association (MMA). All official MIDI standards are jointly developed and published by the MMA in Los Angeles, California, US, and for Japan, the MIDI Committee of the Association of Musical Electronics Industry (AMEI) in Tokyo.

Mentioned in dispatches

A member of the armed forces mentioned in dispatches (or despatches, MiD) is one whose name appears in an official report written by a superior officer and sent to the high command, in which is described his or her gallant or meritorious action in the face of the enemy.

In a number of countries, a servicemember's name must be mentioned in dispatches as a condition for receiving certain decorations.

United Kingdom, British Empire, and Commonwealth of Nations

In the British Armed Forces, the despatch is published in the London Gazette.

Soldiers of the British Empire or the Commonwealth of Nations who are mentioned in dispatches but do not receive a medal for their action, are nonetheless entitled to receive a certificate and wear a decoration. For 1914–1918 and up to 10 August 1920, the decoration consisted of a spray of oak leaves in bronze. This decoration was only established in 1919, but it had retroactive effect. From 1920 to 1993, the decoration consisted of a single bronze oak leaf, and in the Canadian Armed Forces still does. In a change introduced in 2014 to the British Armed Forces, multiple decorations may now be worn on a single campaign medal for those awarded since 1962. Prior to this change, even if the soldier was mentioned in dispatches more than once, only a single such decoration was worn. In Britain, since 1993, the decoration is a single silver oak leaf. In each case the decoration is pinned or sewn diagonally on to the appropriate campaign medal ribbon. If no campaign medal is awarded, the oak leaf is worn on the left breast of the dress uniform.
