What is MIDI (Musical Instrument Digital Interface)?
MIDI is a protocol that allows electronic musical instruments and computers to communicate. Instead of transmitting audio, MIDI transmits data like notes, velocity, and tempo, enabling creators to transfer audio ideas from one digital device to another.
What are the three types of MIDI?
The three types of MIDI that handle data transmission between devices are:
- MIDI In receives MIDI data from another device, allowing it to control or trigger the receiving instrument or software.
- MIDI Out sends MIDI data from the device to control or communicate with other MIDI-enabled equipment.
- MIDI Thru passes a copy of the MIDI In signal to other devices, allowing the chaining of multiple instruments or controllers.
Why is MIDI better than digital audio?
Since MIDI transmits control data, it’s easier to edit, and the file sizes are much smaller. Digital audio involves actual sound recordings, which makes editing complex, and the file sizes are generally larger.
What is the difference between audio and MIDI interface?
An audio interface converts analog sound like voice or instruments into digital signals for recording and playback. A MIDI interface transmits MIDI data (performance data like notes and velocity) between controllers and computers or other devices. Audio handles sound, while MIDI handles control data. Some modern audio interfaces also include MIDI ports, combining both functions in one device.
