Arduino uno midi system exclusive

After some days working and searching Google, i wrote this code which is working good on pc by sending the message through the serial monitor, but still not working on my keyboard...:frowning:

#include <MIDI.h>
#include <midi_Defs.h>
#include <midi_Message.h>
#include <midi_Namespace.h>
#include <midi_Settings.h>
#define MIDI_SYSEX_ARRAY_SIZE 255
static const unsigned SysExMaxSize = 256;
MIDI_CREATE_INSTANCE(HardwareSerial,Serial, MIDI);
const unsigned int MAX_MESSAGE_LENGTH = 69;
uint8_t Con[23]   ={0x42,0x7F,0x60,0x01,0x01,0x10,0x7D,0x00,0x4E,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};
String C1= "F0 42 7F 60 01 01 10 7D 00 4E 00 00 00 00 00 00 00 00 00 00 00 00 F7";
String off="F0 42 7F 60 01 01 00 7D 00 00 00 00 00 00 00 00 00 00 00 00 00 00 F7";
int led = 13;
int ledState = LOW;


void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
  pinMode(led, OUTPUT);
 Serial.begin(9600);

}

void loop() {

 //Check to see if anything is available in the serial receive buffer
 while (Serial.available() > 0)
 {
   //Create a place to hold the incoming message
   static char message[MAX_MESSAGE_LENGTH];
   static unsigned int message_pos = 0;
  
   //Read the next available byte in the serial receive buffer
   char inByte = Serial.read();
int S = MIDI.getSysExArray();
char X = MIDI.getSysExArray();
byte Z = MIDI.getSysExArray();


   //Message coming in (check not terminating character) and guard for over message size
   if ( inByte != '\n' && (message_pos < MAX_MESSAGE_LENGTH - 1) )
   {
     //Add the incoming byte to our message
     message[message_pos] = inByte;
     message_pos++;
     
   }
   //Full message received...
   
   else
   {
     //Add null character to string
     message[message_pos] = '\0';
  String Y = message;
  
     //Print the message (or do other things)
   
     if (Y == off && ledState == HIGH)
 {
 ledState = LOW;}
 if (Y == C1 && ledState == LOW)
 {
 ledState = HIGH;}
     
     //Reset for the next message
     message_pos = 0;
    
   Serial.println(S);
    Serial.println(X);
     Serial.println(Z); 
     Serial.println(Y);
     Serial.println(message); 
   }
  }
  digitalWrite(led, ledState);
 }
