I maked midi octapad using arduino mega 2560 board. But there are two pads not working properly. Are there any kindly person, can repair the code for me? Please help me.

#include <MIDI.h>

#include <MIDI.h>
MIDI_CREATE_DEFAULT_INSTANCE();
byte patchNum = 0;

#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int pinRead;
char pinAssignments[8] ={'A0','A1','A2','A3','A4','A5','A6','A7'};
byte PadNote[8] =    { 60,61,62,63,64,65,66,67};

int MaxPlayTime[8] = { 40,40,40,40,40,40,40,40};              
#define  midichannel 10;                              
boolean VelocityFlag  = false;

int PinPlayTime[8] =   { 0,0,0,0,0,0,0,0 };                  
byte status1;
int pin = 0;     
int hitavg = 0;

void setup() {
Serial.begin(31250);  
pinMode(8,INPUT_PULLUP);
pinMode(9,INPUT_PULLUP);
MIDI.begin(MIDI_CHANNEL_OMNI);
lcd.begin(16, 2);
lcd.setCursor(3,0);
lcd.print ("WELL COME");
lcd.setCursor(1,1);
lcd.print ("HARSHA PRODUCT");


delay(3000);
lcd.clear();


lcd.setCursor(0,0);
lcd.print("H DRUM + MIDIPAD");
lcd.setCursor(0,1);
lcd.print("CHANNEL = A  0    ");  

}

More people will see your code if you post it as described in the how to use this forum sticky.

But there are two pads not working properly.

What does "not working" mean?

3

And which two pads?

A6 and A7 pads not working.
See throught fl studio software, A0 to A5 pads are send the. But A6 and A7 pads are not send note.

5 
char pinAssignments[8] ={'A0','A1','A2','A3','A4','A5','A6','A7'};

Start with the fact that 2 characters like A0 don't fit in to a char variable. It's not easy to see how any of it is working.

BTW why is MIDI.h included twice?
