MIDI In/Out

MIDI In and Out are ports on musical equipment used to connect devices for digital communication. MIDI Out transmits control signals—such as notes, velocity, and other performance data—from one instrument or device, while MIDI In receives this data. This allows devices like keyboards, synthesizers, and computers to synchronize, control, or trigger other equipment remotely. Essentially, MIDI lines facilitate the transfer of musical performance information, enabling coordinated playback, recording, and editing in a musical setup without transmitting actual audio signals.
