I want to learn about arduino

hi...
I'm very interested in your code, but here I also have a code for a keyboard or piano, with a standard number of 61 keys, and I also have a separate code specifically for pitch bend, which I want to ask, how do I combine it into These 2 codes, I really hope for all of my friends' help

and this is my code...

#include <MIDI.h>
#include <Keypad.h>

const byte ROWS = 8; //turun
const byte COLS = 8; //samping

char keys[COLS][ROWS] = {
{36, 37, 38, 39, 40, 41, 42, 43},
{44, 45, 46, 47, 48, 49, 50, 51},
{52, 53, 54, 55, 56, 57, 58, 59},
{60, 61, 62, 63, 64, 65, 66, 67},
{68, 69, 70, 71, 72, 73, 74, 75},
{76, 77, 78, 79, 80, 81, 82, 83},
{84, 85, 86, 87, 88, 89, 90, 91},
{92, 93, 94, 95, 96, 97, 98, 99}

};

byte rowPins[ROWS] = {2, 3, 4, 5, 6, 7, 8, 9};
byte colPins[COLS] = {A0, A1, A2, A3, A4, A5, 10, A7};
Keypad kpd = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

byte pressed = 32;
byte chanel = 0;

void setup() {
Serial.begin(115200);}

void loop() {

if (kpd.getKeys()){
for (int i = 0; i < LIST_MAX; i++) {
if ( kpd.key[i].stateChanged )   {
pressed = kpd.key[i].kchar + 0; // 0 61key C // 12 49key F //
switch (kpd.key[i].kstate) {  
case PRESSED:
sendMIDI(chanel | 0x90, pressed, 100);
break;
case RELEASED:
sendMIDI(chanel | 0x80, pressed, 64);
break;
   }
 }

}
}
} // End loop

void sendMIDI(byte type, byte note, byte velocity){
Serial.write(type);
Serial.write(note & 0x7F);
Serial.write(velocity);}

and this is the code for the pitch bend.....

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

#include <pitchToNote.h> //

int joyX = 0; //Pitch Bend

int joyY = 0; //CC1 und CC20

int pitchBend = 0;

int controllerWert = 0;

int button = LOW;

int buttonAlt = LOW;

int schalter = 0;

void setup() {

//Serial.begin(9600);} //hairless-midiserial

Serial.begin(31250);} //Midi arduino 16u2

void loop() {

joystickAbfragen();

buttonAbfragen();

}

void joystickAbfragen() {

joyX = analogRead(A0);

if (joyX > 536) {

pitchBend = map(joyX,530,1023,65,127);

sendeMIDI(224,0,pitchBend);

}

if (joyX < 400) {

pitchBend = map(joyX,0,520,0,63);

sendeMIDI(224,0,pitchBend);

}

else if ((joyX > 520 && joyX < 530) && pitchBend != 64) {

pitchBend = 64;

sendeMIDI(224,0,pitchBend);

}

joyY = analogRead(A1);

if (joyY > 528) {

controllerWert = map(joyY,530,1023,0,127);

sendeMIDI(176,1,controllerWert);

}

else if (joyY < 520) {

controllerWert = map(joyY,520,0,0,127);

}

}

void buttonAbfragen() {

if (button == LOW && buttonAlt == HIGH) {

if(schalter == 0){

sendeMIDI(176, 64, 127);

schalter = 1;

}

else {

sendeMIDI(176, 64, 0);

schalter = 0;

}

}

buttonAlt = button;

}

void sendeMIDI(int statusByte, int dataByte1, int dataByte2) {

Serial.write(statusByte);

Serial.write(dataByte1);

Serial.write(dataByte2);

}

and please help me, because I'm having a lot of trouble, combining these 2 codes, I really hope, I can get the solution here
