Casio CZ/ VZ/ FZ - Pro Series

Hi Patrick,

  My CZ5000 was doing the same thing when I first got it. In the 
center of the keyboard there is a brace that supports the top. There 
is a little rubber pad on this brace that keeps the boards in the top 
of the synth from shorting out on the brace or the keybed assembly. 
On my synth this pad was laying in the bottom of the synth because 
the adhesive had gotten old. Remove the top then use a couple of Ty-
Wraps to hold this pad to the top of the brace also make sure the 
brace isn't bent down because something heavy was set on it. Bend it 
up if it is. Voila, now the synth doesn't reset back to A1 and 
restart every time a button is pressed (or randomly). 

  Let me know if you need more help with this... You can e-mail me 
offlist if you wish. I have the Service Manual too.

  I'm not sure about Marcin's midi problem. It almost sounds like a 
midi feedback issue...
