Hello, I'm making a full functional MIDI controller with my Arduino Mega, I'm using my keyboard of 61 keys, 52 keys will be connected to the pins from 2 to 53, the other 9 will be connecte to pins A0 to A8. The keys are simple push buttons. I was using the code from this video:

[![](https://europe1.discourse-cdn.com/arduino/original/4X/2/8/6/286bacf68d360c76026ec2e27a8bccdb3528708e.jpeg "Construye tu propio controlador MIDI") ](https://www.youtube.com/watch?v=dkFy9S-GjIo&t=1029s)

But I couldn't change it in order to work the analog pins, so, I decided to do a research and I ended up with a library called Control Surface, it's quite simple and intuitive!

The problem is that with this code I recive this in my Serial-MIDI program:

With the code of the video I recived the note in channel 1 and with the velocity value:

I need to make this code work like the last photo in order to send the notes:

```arduino
#include <Control_Surface.h> // Include the Control Surface library
#include <MIDI_Interfaces/SerialMIDI_Interface.hpp>

// Instantiate a MIDI over USB interface.
HairlessMIDI_Interface midi;
 
// Instantiate a CCButton object
CCButton button {A1, {MIDI_CC::General_Purpose_Controller_1, CHANNEL_1},};
 
void setup() {
  Control_Surface.begin(); // Initialize Control Surface
}
 
void loop() {
  Control_Surface.loop(); // Update the Control Surface
} 

```

You can declare analog pins as digital inputs and they work the same as any other pins.

Simply replace `CCButton` by `NoteButton`: [Control Surface: NoteButton.ino](https://tttapa.github.io/Control-Surface-doc/Doxygen/de/dcc/NoteButton_8ino-example.html)

Yes! I know, but the problem is that the part of the code that reads the buttons is a loop, and it increases the i index each time it's excuted, and when it goes to the last digital pin, I can't make it jump to the analog pins. It's in the video
