Which of these statements is true regarding MIDI channels?

MIDI (Musical Instrument Digital Interface) channels are designed to transmit control information for musical instruments, and a fundamental characteristic is that all 16 channels can operate at the same time. This allows for the simultaneous transmission of different MIDI messages which can be sent to various instruments or software. They facilitate a versatile and intricate setup for composing and performing music, where multiple devices or virtual instruments can be controlled independently over the same MIDI cable or communication channel.

For example, one can have a synthesizer responding to MIDI channel one, a drum machine on channel two, and a keyboard on channel three all playing together in a session. This capability is essential for complex arrangements, as each channel can transmit distinct performance or note messages to different instruments, enhancing the richness and diversity of the musical output.
