MIDI doesn't generate any sound on its own; instead, it works by sending information, known as MIDI messages, that instruct a receiving device on how to use its own internal mechanisms to create and manipulate sound. Upon receiving MIDI messages, the receiving device interprets MIDI messages and takes corresponding actions. For instance, when a "Note-On" message is received, indicating that a note should begin, the receiving device produces the specified musical sound at the designated pitch and velocity (indicating how forcefully the key was pressed). Similarly, "Control Change" messages adjust parameters like volume, modulation, or filter settings in real-time to shape the sound.
