5. ^Special CCs are CCs that don't correspond to the parameter of any particular effect. Most usually they represent special one-shot control commands for the device (these ones are usually represented by a button on a console), or used internally for bank selection, RPN or data entry, etc.

7. ^Parametric CCs (also known as continuous controller) correspond to the parameter of some particular effect (i.e. depth, strength, delay of effect, etc). Such CCs are usually represented by a rotating knob or fader in mixers.
