Help with Error Teensy40 // Midi Controller

Using Arduino Project Guidance
1

Hey,
I´m using a Teensy40 and I want to build a midi controller using this code:

int controlChange       = 176;
int potiPin[]           = {A0,A1,A1,A3};
int controllerNummer[]  = {20,21,22,23};
int controllerWert[]    = {0,0,0,0};
int controllerWertAlt[] = {0,0,0,0};
int potiWert[]          = {0,0,0,0};


int i = 0;

void Setup(){
  Serial.begin(9600);
  
}

void loop(){
  for (i = 0; i < 3; i++) {
    potiWert[i]  = analogRead(potiPin[i]);
    controllerWert[i] = map(potiWert[i],0,1023,0,127);

    if (controllerWert[i] != controllerWertAlt[i]) {

      Serial.write(controlChange) ;
      Serial.write(controllerNummer[i]);
      Serial.write(controllerWert[i]);

      controllerWertAlt[i] = controllerWert[i];
    }
    
  }
}

Still I´m getting this Error:
c:/users/lenovo/appdata/local/arduino15/packages/teensy/tools/teensy-compile/11.3.1/arm/bin/../lib/gcc/arm-none-eabi/11.3.1/../../../../arm-none-eabi/bin/ld.exe: C:\Users\Lenovo\AppData\Local\Temp\arduino\sketches\EE3798F2C5634DE1B4F6AB0BA4357C3C/....\cores\teensy_avr_teensy40_usb_serial,speed_600,opt_o2std,keys_en-us_5fa0a990ad051d6a9f36b09e7262dd2a\core.a(main.cpp.o): in function main': C:\Users\Lenovo\AppData\Local\Arduino15\packages\teensy\hardware\avr\1.58.1\cores\teensy4/main.cpp:51: undefined reference to setup'
collect2.exe: error: ld returned 1 exit status

exit status 1

Compilation error: exit status 1

My code seems to be right, I have no Idea what this error means, anyone can help?
