Short for “continuous controller” or “control change”, it is a MIDI message that combines a controller number and a value. The value for an individual controller can change over time, allowing incremental manipulation of the corresponding sound or effect, such as increasing/decreasing the string vibrato intensity. You can specify the sound or effect that each CC switches to and controls in each sound library using expression maps. In Dorico Pro, each instrument track has 127 available MIDI CCs, each with a value range from 0 to 127. Because MIDI CC does not use notes on a MIDI keyboard, it allows you to use the full range of MIDI keyboard notes for note input. However, it is therefore harder to trigger MIDI CC whilst recording notes. See also MIDI, PC.
