Buttons too responsive in guitar rig

How do i incorporate that in my code as its a bit beyond me

// include MIDI library
#include <MIDI.h>

// read digital pins number 2, 4, 7, 8
int pushButton2 = 2;
int pushButton4 = 4;
int pushButton7 = 7;
int pushButton8 = 8;

// checks if the button is pressed
int buttonState2 = 0;
int buttonState4 = 0;
int buttonState7 = 0;
int buttonState8 = 0;

// play/stop notes in relation to buttons pressed 
int note2 = 0;
int note4 = 0;
int note7 = 0;
int note8 = 0;

// read potentiometer value
int analogValue = 0;
// maximum MIDI value is 127, first/previous potentiometer
// move has to always be different than previous value
int lastAnalogValue = 128;

void setup() {
  delay (1000);
// slows connection so you dont have to reset board
  MIDI.begin(4);
  // 115200 hairless MIDI
  Serial.begin(115200);
  pinMode(pushButton2, INPUT);
  pinMode(pushButton4, INPUT);
  pinMode(pushButton7, INPUT);
  pinMode(pushButton8, INPUT);
}

void loop() {
  // read state of buttons
  int buttonState2 = digitalRead(pushButton2);
  int buttonState4 = digitalRead(pushButton4);
  int buttonState7 = digitalRead(pushButton7);
  int buttonState8 = digitalRead(pushButton8);
  

  // Button 2
  
  // when button pressed:
  if (buttonState2 == HIGH) {
   // if note not playing
    if (note2 == 0) {
      // play note (note number, velocity, channel)

      MIDI.sendControlChange(80,127,1);
      // note is playing
      note2 = 1;
    }
