Thank you very much I appreciate it. finally i could do it.
I use speedy entry but i guess the shortcut doesn't work with speedy entry. When i hit key 1 to enter a unison it changed the note to 64th note in both speedy and simple menus. I later cusomised it from Edit Keyboard Shortcuts. But i guess it only works while using simple entry :) it doesn't matter the problem is solved thanks tou you both.
