What is MIDI?
In the world of music production, MIDI (Musical Instrument Digital Interface) plays a crucial role in creating, editing, and manipulating musical ideas. Whether you're a beginner or an aspiring producer, understanding MIDI is essential for harnessing the power of electronic music creation.
MIDI, or Musical Instrument Digital Interface, is a standardized protocol that enables electronic musical instruments, computers, and software to communicate with each other. Unlike audio signals that represent sound waves, MIDI transmits digital messages that describe musical events, such as notes, velocities, durations, and more. This data can be used to control synthesizers, virtual instruments, and other devices.
A Lil History
MIDI was developed in the early 1980s to address a pressing need in the music industry: the lack of a standardized method for electronic instruments to communicate with one another. Before MIDI, musicians and producers faced challenges when trying to synchronize synthesizers, drum machines, and computers for musical collaborations and compositions.
In 1983, a group of visionary industry leaders, including Sequential Circuits, Roland Corporation, and Yamaha Corporation, collaborated to create the MIDI 1.0 specification. Their goal was to establish a universal language that would allow different devices to "speak" to each other, unlocking the potential for seamless integration and collaboration in music production. Here is an example of a midi controller that can be used as a mixer or to control multiple effects in your DAW.
Here are some examples of what MIDI does in our DAWS today.
Playing Virtual Instruments: Imagine you have a MIDI keyboard connected to your computer. When you press a key, the keyboard sends a MIDI message to your software, which triggers a virtual instrument like a piano or synthesizer to play the corresponding note.
Recording and Editing: You can record MIDI performances just like you would audio. MIDI data records the timing, pitch, and duration of each note played. This data can be edited, quantized (adjusted to a specific rhythm), and manipulated after recording to achieve the desired musical result.
Automation: MIDI isn't limited to notes. It can also control parameters over time. For instance, you can use MIDI to automate the modulation wheel of a synthesizer, creating dynamic changes in sound.
Note On/Off: MIDI messages can trigger the start (Note On) and end (Note Off) of a musical note. This is the foundation of MIDI's ability to play melodies, chords, and harmonies.
Velocity: MIDI can transmit information about how forcefully a key is pressed, enabling dynamics in music playback.
Control Changes: MIDI messages can also alter effects parameters like volume, modulation, pitch bend, and more. This paves the way for expressive and dynamic sound manipulation.
Program Changes: MIDI can switch between different instrument sounds or presets, allowing for a wide sonic palette.
Sync and Timing: MIDI also handles synchronization and timing information, ensuring devices play in time with one another.
Here is an example of a controller that has almost all of it packed into one. How many controls can you identify?

The birth of MIDI revolutionized music production, propelling electronic music into new realms of creativity. From classic synthesizers to modern digital audio workstations, MIDI has been a cornerstone of music-making. Its ability to bridge the gap between instruments and technology has paved the way for countless musical innovations, collaborations, and genres.
Next time you witness a seamless collaboration between a MIDI keyboard, a digital synthesizer, and a computer running a DAW, remember the humble beginnings of MIDI. It's not just a set of technical protocols – it's a language that musicians and producers use to compose, perform, and breathe life into their artistic visions. Check out this video from Landr!
