Jack, let's not lose our heads here - nobody accused you of making sense! Like you, I tweak this thing often and it makes the whole experience just excellent. While the need for the manual is less and less over time, I keep it handy and seem to learn something new everytime I use it.

I absolutely dreaded fooling with the MX-500 and avoided it as much as possible. Then I needed to pull the manual out when I made changes because I forgot the routine and needed extra hands to use the manual/re-do the 500.
