Developing MIDI applications with DirectMusic

/*
Module : KeybDlg.h
Purpose: Defines the header implementation for the CKeybDlg class
Created: CJP / 10-4-2002
History: CJP / 21-7-2002 
	
	  1. Solved problems with Midi port selection
	  
	  2. Improved built-in keyboard
		
	  3. Supervised the multithread-safe application	

	  4. Improved the interactive interface
