Sounds to me like the backup battery died and you need to reset the unit.
I don't know how to do that on a CZ1 but it will be in the manual.
The manual is available online if you don't have one.

Hello,
I have a CZ1 , that was my first synthesizer , but one day I
turn it on and if you touch any key , it sounds a very high
note and hold on , if you play more keys it adds up but with
high notes.
Some keys sound with erratic tune and the other keys sound
with high tune and stay hold on after the key is depressed
until power off the synth.
If you play throught MIDI , all is correct, all notes
, program change , etc.
Anyone have any idea what can happen ?.
Thank you in advanceMessage
