Casio CZ/ VZ/ FZ - Pro Series

Hmmm... could be the built in relais, to prevent klicks it connects 
the output signal to ground until the synth is completely up. I had 
that problem with two Casio Keyboard, a CZ-1 and a friends FZ-1. When 
it fails the output tends to be very low, but randomly restores to 
normal. One solution is to replace the relais another one is simply 
to bypass it...

...Summa
