it could be a bad diode on the keyboard circuit and it could be a higher 
note key

if you use a chromatic tuner it could tell you what key is held by its 
notation so you have a better idea whay key it is

i would remove the keybed and remove all keys for inspection of the key 
contact boards

i dont have a cz1 so cant comment on what type but if its the common bubble 
contacts they can become stuck if the key was removed and not put back 
properly and its held on note on

but after removing all keys and you just press the bubble contacts for each 
key note and you are still getting the problem

then i would look to testing the diodes is there a bank of keys that dont 
sound but triggers the same note as there done in banks of octaves

  Hi all,
  I own a CZ1, this is my first synthesizer, but when touch a note in 
keyboard it produces sound but really it is not a right note, too high, 
and/or the sound is continuos, but a key is depressed still sound until 
power is of.
  Anyone have an idea?
  Thank you in advance
