i remember using fruity loops and using my computer keyboard as a midi controller (for example, playing a piano instrument using my comp keyboard instead of clicking the blocks and usings a keyboard midi controller). i was wondering how i would be able to do that with reason 4.0. thanks

is there another way besides using that program? like, usings the letter keys on my PC keyboard?

That program does let you use the letter keys on your keyboard. No offense but if I link you to something helpful, try to at least read it.
