This is for a midi controller that has 3 buttons and 1 pot. I simply want to add 2 more pots and keep the rest of the code intact. I want to add more later but to learn and understand, if someone could just show me how I could add 2 more pots. I'd be grateful. I have 3 pots connected to A0, A1 and A2. The buttons and 1 pot work, I just need to adjust the code for 2 more pots.
HTML Code:
#include <Bounce.h>

// the MIDI channel number to send messages
const int channel = 1;

Bounce button0 = Bounce(0, 5);
Bounce button1 = Bounce(1, 5);
Bounce button2 = Bounce(2, 5); 

byte current_value_1; 
byte previous_value_1; 

void setup() {
  analogReadResolution(7); // set the analog read resolution to 7 bits (a range of 0 - 127)
  analogReadAveraging(32); // average the analog value by averaging 16 readings
  pinMode(0, INPUT_PULLUP);
  pinMode(1, INPUT_PULLUP);
  pinMode(2, INPUT_PULLUP);
  
 }

void loop() {
  button0.update();
  button1.update();
  button2.update();
  
  current_value_1 = analogRead(0); 
  
  if (button0.fallingEdge()) {
    usbMIDI.sendNoteOn(60, 99, channel);  // 60 = C4
  }
  if (button1.fallingEdge()) {
    usbMIDI.sendNoteOn(61, 99, channel);  // 61 = C#4
  }
  if (button2.fallingEdge()) {
    usbMIDI.sendNoteOn(62, 99, channel);  // 61 = C#4
  }
  
  if (button0.risingEdge()) {
    usbMIDI.sendNoteOff(60, 0, channel);  // 60 = C4
  }
  if (button1.risingEdge()) {
    usbMIDI.sendNoteOff(61, 0, channel);  // 61 = C#4
  }
  if (button2.risingEdge()) {
    usbMIDI.sendNoteOff(62, 0, channel);  // 61 = C#4
  }
  if(current_value_1 != previous_value_1) {
    previous_value_1 = current_value_1;
    usbMIDI.sendControlChange(1, current_value_1, 1); // send continuous controller message
  }

 
}
