I just received mine and wish I had known about it when I got my kn7000 21/2 years ago. I have learned a great deal about the basics of the keyboard for the first time. This manual is a primer and Alec's other book goes from there.
I would advise anyone who hasn't got one to take Walt up on this last offer.
