Receive note not from USB, but from 5DIN

Hi, how to receive midi note on arduino, not from usb, but from 5din?

I'm using a sketch from the exsample library that lights up a diode when a note (C4) is received via USB. And I need to receive note, from port 5din.

    #include <Control_Surface.h> // Include the Control Surface library
    
    // Instantiate a MIDI over USB interface.
    USBMIDI_Interface midi;
    
    using namespace MIDI_Notes;
    
    // Instantiate the LED that will light up when middle C is playing
    NoteValueLED led = {
      LED_BUILTIN,             // Pin of built-in LED
      {note(C, 4), CHANNEL_1}, // Note C4 on MIDI channel 1
    };
    
    void setup() {
      Control_Surface.begin(); // Initialize Control Surface
    }
    
    void loop() {
      Control_Surface.loop(); // Update the Control Surface
    }

See https://tttapa.github.io/Control-Surface-doc/Doxygen/d3/df7/midi-tutorial.html#midi_md-midi-interfaces, you can use HardwareSerialMIDI_Interface.
