Description
MIDI RX (MIDI Receive) allows your controller to react to incoming MIDI messages from software or hardware. It can update LEDs and control elements in real time, keeping your controller synchronized with your setup.
Parameters
The MIDI Block includes an LED and element value sync feature. If your DAW or hardware sends back the same MIDI message that the element transmits, the controller automatically keeps the LED state and element value synchronized.
