CC4

CC4 is an acronym used in multiple domains to denote a fourth version, category, or model associated with the letters CC. Because CC can stand for different phrases in different contexts, CC4 does not have a single universally accepted meaning; its interpretation depends on the field, organization, and labeling scheme involved.

In music technology, CC4 usually designates a Control Change message with the controller number 4 in the MIDI specification. This message is commonly associated with a foot pedal or other external control, but the exact function is device-defined and may vary between synthesizers and software.

In licensing and open content discussions, CC4 is sometimes used informal ly to refer to the Creative Commons 4.0 framework. The official designations are CC BY 4.0, CC BY-SA 4.0, etc., and most sources avoid using the shorthand "CC4." Nevertheless, some casual references may encounter the term.

Beyond these contexts, CC4 can appear as a product code, model number, course code, or internal version label within organizations. In such cases, its meaning is defined by the specific catalog or project documentation.

Researchers and users encountering CC4 should rely on surrounding context or seek explicit clarification to determine the intended meaning. When possible, refer to the full form (for example, "Control Change 4" or "Creative Commons 4.0") to avoid ambiguity.
