# Function Annotations for MIDI Controllers

It is also possible to create function buttons that display the value of a specific MIDI controller on a specific MIDI channel. And when you tap the button, a slider appears, allowing you to change the controller value.

To do this, create a normal function button and add "MIDI CC Button" as the only action.
