What is MIDI?

MIDI (Musical Instrument Digital Interface) is a standardized communication protocol in music production that allows electronic instruments, computers, and devices to exchange musical information. MIDI has revolutionized music production, allowing devices to communicate and exchange musical data. In this blog post, we’ll explore the benefits, limitations, and creative possibilities MIDI brings to musicians and producers.

What is MIDI?

MIDI is a standardized communication protocol that allows electronic instruments, computers, and other devices to exchange musical information and control messages. Instead of transmitting audio, MIDI transmits digital data representing elements like note pitches, durations, dynamics, and more. This enables musicians and producers to record, edit, and playback performances, control synthesizers, and virtual instruments, and synchronize various devices.

What is MIDI used for?

MIDI is used for transmitting musical data and control information between electronic devices, such as keyboards, synthesizers, computers, and software, enabling them to communicate, synchronize, and interact in music production, performance, and composition. It allows musicians and producers to play virtual instruments, trigger sounds, record and edit musical performances, control parameters, automate effects, and synchronize multiple devices

What are the benefits of MIDI?

Benefits of MIDI include universal compatibility, real-time communication, small file size, non-destructive editing, and being downloadable and reusable.

  • Universal compatibility: MIDI is a widely adopted industry standard, ensuring compatibility among different MIDI-enabled devices, software, and hardware. This universal standard allows musicians and producers to seamlessly exchange musical data and control information across various platforms without worrying about proprietary formats or incompatibility issues.
  • Real-time communication: MIDI offers real-time communication between devices, allowing musicians to play and control virtual instruments, synthesizers, and other MIDI-enabled equipment with instant responsiveness. This real-time communication is crucial for live performances and studio recordings where timing precision is essential.
  • Small file size: MIDI files have a relatively small size compared to other audio formats like WAV or MP3. Since MIDI files contain instructions and data for synthesizing sound rather than actual audio samples, they are lightweight and occupy much less storage space. This makes MIDI an efficient choice for storing and transmitting musical data over the internet.
  • Non-destructive editing: MIDI data is editable in a non-destructive manner. Unlike audio recordings, where changes are permanent once recorded, MIDI allows for easy modification of musical events, such as note placement, velocity, and timing, without affecting the original source. This flexibility makes MIDI ideal for fine-tuning compositions and arrangements during the music production process.
  • Downloadable and reusable: Another benefit of MIDI is its availability as downloadable chord progressions or musical sequences from existing songs. Musicians and producers can find MIDI files online that represent specific melodies, chord progressions, basslines, and other musical elements used in popular songs. By accessing these MIDI files, artists gain the advantage of using pre-composed musical data as a starting point for their own creations.

What are the disadvantages of using MIDI?

Disadvantages of MIDI include dependency on sound sources, inability to capture human expression, and latency issues.

  • Dependency on sound sources: MIDI itself does not produce sound; it only carries musical data. To hear the sounds represented by MIDI, it requires external sound sources such as synthesizers or virtual instruments. The quality of the final output heavily relies on the capabilities and sound libraries of these external devices. As a result, the overall sound and timbre will vary depending on the available sound sources, limiting the expressiveness and authenticity of the music.
  • Inability to capture human expression: MIDI is a digital protocol designed to transmit musical data in a precise and quantized manner. While it efficiently represents pitch, duration, and other musical parameters, it lacks the ability to capture the subtleties and nuances of human expression. Variations in timing, dynamics, and articulations that make a performance unique are challenging to convey through MIDI alone. As a result, MIDI-driven music may sometimes sound mechanical or lack the human touch found in live performances.
  • Latency issues: Latency refers to the slight delay that can occur between triggering a MIDI event and hearing the resulting sound. This latency is caused by factors such as the performance of the MIDI interface, the processing speed of the connected devices, and the complexity of the MIDI data being transmitted. In real-time applications, such as live performances or interactive music systems, even slight latency can disrupt the performer’s experience and the overall musical flow.

How is MIDI stored?

MIDI data is stored as a series of digital messages, represented in binary code. Each MIDI message consists of a status byte indicating the type of event (e.g., note-on, control change) and one or more data bytes containing specific information (e.g., note number, velocity). These messages are organized chronologically and saved in a standardized file format, known as Standard MIDI Files (SMF), which allows for seamless interchangeability among MIDI-enabled devices and software applications. MIDI data is commonly saved with the “.mid” file extension.

Who invented MIDI and why?

MIDI was co-invented by Dave Smith and Ikutaro Kakehashi. They introduced the MIDI standard in 1983 to address compatibility issues between different electronic musical instruments and to enable seamless communication and data exchange. The primary goal was to create a unified protocol that allowed musicians, producers, and manufacturers to connect MIDI-enabled devices, share musical information, and control parameters universally, revolutionizing music production and performance while fostering collaboration and innovation in the music industry.

How has MIDI changed music?

MIDI has revolutionized music by enabling digital communication between instruments and computers, facilitating seamless integration of technology into the creative process. It empowered musicians to explore limitless sound possibilities through virtual instruments, democratized music production by making it more accessible, revolutionized live performances with real-time control, and facilitated collaborative composition and global sharing, fundamentally reshaping the landscape of modern music creation and performance.

How can I use MIDI?

You can use MIDI by connecting MIDI-enabled devices (such as keyboards, controllers, or computers) through MIDI cables or USB ports. Create or import MIDI data in your digital audio workstation to trigger virtual instruments or external synthesizers, controlling pitch, duration, velocity, and more. Edit, arrange, and layer MIDI data to compose music, add expressive details like modulation and aftertouch, and fine-tune timing. Use MIDI for live performances, recording, and collaboration, leveraging its versatility and non-destructive editing for a wide range of musical styles and applications.
