MIDI

Music tools can talk to each other.

This system is called MIDI. It sends notes from one tool to another.

One keyboard can play many different sounds. It can sound like a piano or a flute. It can even sound like a whole orchestra. This helps people make songs at home. One person can make a very big sound. It is a clever way to make music.

MIDI is a way for music tools to talk to each other.

It stands for Musical Instrument Digital Interface. This system lets computers and electronic instruments connect. They can play, edit, and record music together.

When you press a key, it makes a MIDI event. This is a digital message. It tells other tools which note to play. It also shares the timing and how hard the note was hit. You can use one keyboard to control many sounds. It might sound like a piano or a flute. It can even sound like a whole orchestra.

Before MIDI, different brands of music tools could not talk. This changed in 1983. Two men, Dave Smith and Ikutaro Kakehashi, helped lead the way. They wanted a simple way for all tools to work together. Now, one person can make a huge sound. They can do this with just a few small tools. MIDI helps people make music at home. It is still used by musicians today.

Instead of sending actual sound, MIDI sends instructions. This allows a musician to play, edit, and record music very easily. Because the files are small, they are simple to move and change. This technology changed how people make music in studios and at home.

\n\nWhen you play a MIDI instrument, it creates a MIDI event. This event is a digital message that contains specific musical instructions. It tells other devices the pitch of the note and the timing. It also shares the velocity, which is how hard the note was hit.

One MIDI cable can carry up to sixteen different channels of data. Each channel can be sent to a separate device. This means one keyboard can trigger many different sounds at once. You could play a single note that sounds like a piano and a flute together.

\n\nBefore MIDI, making electronic music was a very hard job. Different companies made instruments that could not talk to one another. In 1981, Ikutaro Kakehashi from Roland proposed a new standard. He spoke with Dave Smith from Sequential Circuits to find a better way.

They wanted a system that was simple and cheap for everyone. Smith and engineer Chet Wood helped design a universal interface. Smith suggested the name MIDI because it was better than other ideas. The official MIDI specification was finally published in August 1983.\n\nMany important instruments were released during the early days of MIDI. In 1983, the Roland Jupiter-6 and Prophet 600 were among the first. That same year, the Roland TR-909 became the first MIDI drum machine.

The MIDI Manufacturers Association was formed in 1984 in Chicago. They work to keep the standard updated for new technology. In 2020, the new MIDI 2.0 standard was introduced at a big show. Even though it is many years old, the original design is still used today.

Musical Instrument Digital Interface, commonly known as MIDI, is a technical standard for communication. It describes a protocol, a digital interface, and the electrical connectors used to link electronic musical instruments. This system also connects computers and other related audio devices.

MIDI is essential because it allows diverse devices to play, edit, and record music together. It does not transmit actual audio signals like a microphone does. Instead, it transmits digital data that acts as a set of musical instructions. This distinction makes MIDI files very small and easy to manipulate compared to traditional audio recordings.

To understand how MIDI works, imagine a conductor giving orders to an orchestra. When a musician interacts with a MIDI controller, such as a keyboard, the device converts that action into a MIDI event. A MIDI event is a digital message containing specific instructions. These instructions include the pitch of the note, the timing of when it is played, and the velocity, which describes how hard the key was struck.

A single MIDI cable can carry data across up to sixteen different channels. Each channel can be routed to a separate device. This means one single controller can trigger a drum machine, a synthesizer, and a sound module simultaneously.

This capability allows a musician to create a massive, layered sound from a very small amount of hardware.

MIDI technology offers several distinct functional applications. The first is instrument control, where one device triggers another. For example, a sequencer can send instructions to a sound module to play specific beats. Musicians can also use MIDI for remote control of instrument parameters. These parameters include volume, effects, and timbre.

Using a continuous controller number, or CCN, a musician can use knobs or sliders to change settings like reverb time or filter frequency. The second major application is composition. Because MIDI records instructions rather than sound, composers can use Digital Audio Workstations (DAWs) to edit music easily. They can change the tempo, the key, or even the specific instruments used after the performance is recorded.

Before MIDI was standardized, the electronic music industry faced a major problem with interoperability. In the early 1980s, different manufacturers used their own proprietary standards to synchronize instruments. These included systems like CV/gate, DIN sync, and Digital Control Bus (DCB). Because these systems were not compatible, instruments from different companies could not communicate. This limitation hindered the growth of the electronic music industry.

To solve this, Ikutaro Kakehashi, the president of Roland, proposed creating a universal standard in June 1981. He reached out to Tom Oberheim and later spoke with Dave Smith, the president of Sequential Circuits.

Dave Smith and engineer Chet Wood worked to devise a universal interface based on Roland's DCB. They proposed this standard in a paper titled "Universal Synthesizer Interface" in October 1981. While Kakehashi initially suggested the name Universal Musical Interface (UMI), Smith proposed the name Musical Instrument Digital Interface instead. The MIDI specification was officially published in August 1983. The first instruments to feature this technology were the Roland Jupiter-6 and the Prophet 600.

In that same year, the Roland TR-909 became the first MIDI drum machine, and the Roland MSQ-700 became the first MIDI sequencer.

The significance of MIDI to the music industry cannot be overstated. It allowed for a rapid expansion in the production of electronic instruments and music software. By allowing one device to control many others, it reduced the amount of heavy hardware musicians needed to carry. MIDI also helped establish the era of home recording. Artists could compose and arrange music in a home environment before going to an expensive studio. This reduced costs and changed how music was produced. In 2005, Dave Smith's original MIDI specification was inducted into the TECnology Hall of Fame for its enduring impact on audio technology.

Today, MIDI continues to evolve and connect with modern computing. The standard has been adapted to work with USB and FireWire connections. The MIDI Manufacturers Association (MMA) and the MIDI Committee oversee the development of new versions. A new standard, MIDI 2.0, was introduced at the 2020 Winter NAMM Show.

Even with these updates, the core concept remains the same. MIDI acts as a universal language that enables cooperation between different technologies, much like USB serves the world of computing.
