What is the name of the digital interface that allows communication between digital instruments and computers?

The digital interface that allows communication between digital instruments and computers is known as MIDI, which stands for Musical Instrument Digital Interface. MIDI is specifically designed for musical equipment and enables the transmission of performance data such as note information, velocity, and control changes. This allows different instruments and computers to communicate effectively, making MIDI essential for music production, recording, and performance.

In contrast, USB is a general-purpose interface used for various devices beyond just musical ones. While it can be used to connect musical instruments to computers, it does not have the specific capabilities of MIDI for musical data communication. FFT refers to a mathematical algorithm used for analyzing frequency components of signals, which is not relevant to instrument communication. AI involves computer systems simulating human intelligence but does not pertain to the transmission of musical data between devices.
