Does anyone produce programs that allow you to play into your computer and it prints out the sheet music and guitar tablature as well? If so which are the more user friendly?

the closest thing i remember is Harmoniser(?), which works out the key your playing in, i dont think it'd work on complex things but simple things it will work it out.
I called Guitar Center and was told Roland (roland.com) sells a midi pickup to attach to your guitar and that they (Guitar Center) sell the soft ware. I gotta go check it out!
i know on the drumline movie, they had some machine hooked up to their drums and it printed out what they played. but i didn't know if that was real or not since in a movie, but kinda sounds like what gunns was talkin about
