Multitouch recording of Piano keys

I have made a multitouch piano in which i have a class CMIDIKeyboard which consist of following function ie OnKeyUp, OnKeyDown, OnLbuttonUp, OnLButtonDown, OnLButtonMove and OnTouchMessage

In OnTouchMessage i am handling 3 events ie TOUCHEVENTIF_DOWN, TOUCHEVENTIF_UP and TOUCHEVENTID_MOVE.

Under TOUCHEVENTIF_UP i am handling message as follows

for (unsigned int i = 0; i < cInputs; i++)
      {
					
       if (pInputs[i].dwFlags && TOUCHEVENTF_DOWN)
	  {               
            if(m_IsInitialized )
	     {
		 CRect rect;
		 TOUCHINPUT ti = pInputs [i];                       
                 if (ti.dwID != 0) 
		  {    // Do something with your touch input handle.
                      ptInput.x = TOUCH_COORD_TO_PIXEL (ti.x);
                      ptInput.y = TOUCH_COORD_TO_PIXEL (ti.y);
		      ScreenToClient ( &ptInput);
		      points [ti.dwID] [0] = ptInput.x;
                      points [ti.dwID] [1] = ptInput.y;
		      CPoint point1=CPoint(points[ti.dwID][0],points[ti.dwID][1]);
		      m_CurrKey=CPianoCtrl::FindKey(point1);				                                 
		      m_Keys[m_CurrKey]->NoteOn(m_NoteOnColor,rect);
		      NoteUporDwn='d';
		      NoteIdPiano=m_LowNote+m_CurrKey;
	              NotifyNoteOn(m_LowNote+m_CurrKey);
		      findchords(m_LowNote+m_CurrKey);
		     ((CDemoDlg*)GetParent())->displaychords(CPianoCtrl::dischords);
		       
	              InvalidateRect(&amp;rect);
							                                          
	        }
		if(RecordState==true)
	       {	
		 RecordNo++;
		 PreviousTime=Current;
		 GetSystemTime(&amp;Current);
		 DWORD el= (Current.wMilliseconds+Current.wSecond*1000+Current.wMinute*60000+Current.wHour*3600000)-
					(PreviousTime.wMilliseconds+PreviousTime.wSecond*1000+PreviousTime.wMinute*60000+PreviousTime.wHour*3600000);
		ElapsedTime.push_back(el);
    	        CString temp;
		temp.Format("%ds.",el);
		WriteString+=temp;
		Event.push_back(5);
		TouchInputDownm_CurrKeys.push_back(m_CurrKey);
		TouchInputDownm_LowNote.push_back(m_LowNote+m_CurrKey);
		TouchInputDownCInput.push_back(cInputs);
		 TouchDown.push_back(true);
		if(CPianoCtrl::m_IsInitialized)
		{
			cout(CPianoCtrl::NoteUporDwn);
			NI=CPianoCtrl::NoteIdPiano;
			CString temp;
			temp.Format("%dd.",NI);
			WriteString+=temp;
	         }
	}  
		 CWnd::OnTouchMessage(wParam,lParam);
     }
						  
  }
  else if()
  {
   }
  else if()
  {
   }
//remaning code

}

and recording is played as follows-

void CMIDIKeyboard::PlayRecording()
{
		int KDownI=0;
		int KUpI=0;
		int MDwnI=0;
		int MUpI=0;
		int MmoveI=0;

		int TDu=0;

		int nTotalRecords=ElapsedTime.size();
		 
		for(int i=0;(i<=nTotalRecords)&&(((CDemoDlg*)GetParent())->SongPlayrec==true);i++)
		{
		    if(i==nTotalRecords)
			{
				return;
			}
			if(i>0)
			
			XSleep(ElapsedTime[i]);
			if((Event[i]==0)&&(((CDemoDlg*)GetParent())->SongPlayrec==true))
			{
				if(KeyDown[KDownI]==true)
				{
					OnKeyDown(m_KeysRecordDwnChar[KDownI],m_KeysRecordDwnRepCnt[KDownI],m_KeysRecordDwnFlags[KDownI]);
					KDownI++;
				}
			}

			if((Event[i]==1);(((CDemoDlg*)GetParent())->SongPlayrec==true))
			{
				if(KeyUp[KUpI]==true)
				{
		
				OnKeyUp(m_KeysRecordUpnChar[KUpI],m_KeysRecordUpnRepCnt[KUpI],m_KeysRecordUpnFlags[KUpI]);
					KUpI++;

				}
			}
			
			if((Event[i]==2);(((CDemoDlg*)GetParent())->SongPlayrec==true)&& (! TOUCHEVENTF_DOWN))
			{
				if(MouseLDown[MDwnI]==true)
				{
					OnLButtonDown(MouseRecordLDwnFlags[MDwnI],MouseRecordLDwnPoint[MDwnI]);
					MDwnI++;
				}
			}
		
			if((Event[i]==3)&&(((CDemoDlg*)GetParent())->SongPlayrec==true)&&(!TOUCHEVENTF_UP))
			{
				 if(MouseLUp[MUpI]==true)
				{
					OnLButtonUp(MouseRecordLUpFlags[MUpI],MouseRecordLUpPoint[MUpI]);
					MUpI++;
				}
			}
		
			if((Event[i]==4);(((CDemoDlg*)GetParent())->SongPlayrec==true))
			{
				if(MouseDrgMove[MmoveI]==true)
				{
					OnMouseMove(MouseRecordMoveFlags[MmoveI],MouseRecordMovePoint[MmoveI]);
					MmoveI++;
				}
			}
			if((Event[i]==5);(((CDemoDlg*)GetParent())->SongPlayrec==true))
			{
				 
				//m_HasCapture=false;
				
				CRect rect;
				if(TouchDown[i]==true)
				{
										m_Keys[TouchInputDownm_CurrKeys[i]]->NoteOn(m_NoteOnColor,rect);
				      InvalidateRect(rect);
					
					NotifyNoteOn(TouchInputDownm_LowNote[i]);
		
					 //findchords1(TouchInputDownm_LowNote[i]);
				    //InvalidateRect(&rect);			 
					//TDw++;
				  }
						
			}
			if((Event[i]==6)&&(((CDemoDlg*)GetParent())->SongPlayrec==true))
			{
			   
			
				CRect rect;
				if(TouchUp[i]==true)
				{
					
					m_Keys[TouchInputUpm_CurrKey[i]]->NoteOff(rect);
				    InvalidateRect(&rect);
					
					NotifyNoteOff(TouchInputUpm_LowNote[i]);
					 findchords1(TouchInputUpm_LowNote[i]);
				    InvalidateRect(&rect);			 
								
					//TDu++;
				}
				
			}
			else
			{
				/* Do nothingg*/
		
			}

				cout(i);	
		}cout("end of for loop");
	
		
	
}

Can anybody please guide me and correct me for event==5 and event==6 condition handling, as per current output for single touch code is correct. If the multitouch and number of touch increases more than 1 the application hangs.Help please..
