Hi Anthony,
The KN7 also has the panel memory buttons on the right hand side; same as your PR.

Did you know that you can assign panel memory control functions (increment/decrement PM numbers and banks) to the pedals on your piano? Look on page 121 in your manual.

I find this feature extremely useful as it enables me to change PM locations without taking hands off the keyboard. It also eliminates the sometimes inconvenient left hand reach to the PM controls located on the right hand side of the instrument.

Regards,
George
