Control Change (CC)

CC Number needs to be 1,2,3,4 to action on loop 1,2,3,4.

Loop Action:

• Toggle: CC Value = 64
• Turn Off: CC Value < 64
• Turn On: CC Value > 64

Examples:

• CC Number = 2 and CC Value = 64: Toggle loop 2 state
• CC Number = 3 and CC Value = 0: Turn OFF loop 3
• CC Number = 3 and CC Value = 100: Turn ON loop 3
