#include <MIDI_Inputs/LEDs/MCU/VULEDs.hpp>
A MIDI input element that represents a Mackie Control Universal VU meter and displays its value using LEDs.
NumLEDs | The number of LEDs for the VU meter display. Recommended value is 12, because this is the range that's sent over MIDI. |

leds | The pins with the LEDs connected. |
track | The track of the VU meter. [1, 8] |
channelCN | The MIDI channel [Channel_1, Channel_16] and Cable Number [Cable_1, Cable_16]. |
decayTime | The time in milliseconds it takes for the value to decay one step. The MCU protocol uses 300 ms per division, and two steps per division, so the default is 150 ms per step. Some software doesn't work if the VU meter decays automatically, in that case, you can set the decay time to zero to disable the decay. |
