A "Control Surface" refers to a physical interface used to manipulate software or hardware in music production, audio engineering, or video editing. It typically includes knobs, sliders, buttons, and touch-sensitive pads that allow users to control various parameters, such as volume, effects, and playback. These devices enhance the creative process by providing tactile feedback, making it easier to adjust settings in real-time. Popular examples of control surfaces include the MIDI controller, DAW (Digital Audio Workstation) controllers, and mixing consoles, which are widely used by musicians and producers to streamline their workflow.
