I am sure that players of keyboards find it tough to get around with the button pushing.  Here is a way to eliminate most of it.  Reqiires work in the beginning but pays off later.  If you already know this please excuse me.
RIGHT 1
 1.  Using the Technics KN7000 push (Right 1) then (Part Select Right 1).
2.  Go to (Sound Group) and select in each group the (Sound) you would like to use.
Even if you do not use the sound, select the one you might use, if you have to.
3.  Next select (Sound Group) then (Sound) of the one you are actually going to use.
4.  Save into (Panel Memory 1) and (Expand).
RIGHT 2
 1.  Using the Technics KN7000 push (Right 2) then (Part Select Right 2).
2.  Go to (Sound Group) and select in each group the (Sound) you would like to use.
Even if you do not use the sound, select the one you lmight use, if you have to.
3.  Next select (Sound Group) then (Sound) of the one you are actually going to use.
4.  Save into (Panel Memory 1) and (Expand).

LEFT

1.  Using the Technics KN7000 push (Left) then (Part Select Left).
2.  Go to (Sound Group) and select in each group the (Sound) you would like to use.
Even if you do not use the sound, select the one you might use, if you have to.
3.  Next select (Sound Group) then (Sound) of the one you are actually going to use.
4.  Save into (Panel Memory 1) and (Expand).

Now when you recall (Panel Memory 1) for a song you have 17 (Right 1) registrations. 17 (Right 2), 17 (Left) registrations just by pressing the (Sound Group then (Sound).  Any time during your playing.  This is impressive to be able 51 registrations on (Panel Memory 1).  The possibilities are endless.
I believe this technic can be used on any brand of keyboard that can save registrations.  Names will be different but the buttons do the same things!
