onscreen piano keyboard in mac reaper?

How do you get the onsceen piano to work with macbook reaper? (i can get it to work in bootcamp windows xp reaper). thanks superkristen

What doesn't work for you? Can you not find the keyboard, or do you get no response/input? If you would supply more detail, someone here can probably help you. ~D

I can get the virtual piano keyboard up on the screen, but I can't get it to play anything. Also, Are there any virtual instruments I can use with it? thanks superkristen
