How many separate channels of MIDI information can a single MIDI cable transmit?

A single MIDI cable can transmit 16 separate channels of MIDI information. This specification is rooted in the MIDI (Musical Instrument Digital Interface) protocol itself, which was designed to allow electronic musical instruments and devices to communicate with each other. Each channel can carry its own stream of MIDI messages, which can represent various types of musical performance data, such as note on/off messages, control changes, and program changes, among others.

The design accommodates up to 16 channels to provide flexibility and functionality for musicians and producers working with multiple instruments or tracks. This limitation allows for efficient data handling without requiring excessive cabling or complex setups, which was particularly crucial in the early days of MIDI technology. Thus, when considering a single MIDI cable, the capacity of 16 channels is a key aspect of MIDI's functionality in modern music production.
