control change

Control change is a type of MIDI message, abbreviated CC, that tells a pedal to do something specific, such as turning a delay's mix or feedback up or down¹. In a rig, it lets guitar pedals be controlled or switched remotely, alongside Program Change messages². Pedals such as the Strymon El Capistan V2 execute MIDI Control Change commands, MIDI clock sync, and access to 300 preset locations³. Expression pedals can send Control Change messages over MIDI, and modules can convert an expression pedal's analog value into Control Change commands⁴⁵. Some controllers transmit multiple Control Change messages on an appointed MIDI channel⁶.
