Casio CZ/ VZ/ FZ - Pro Series

Hi,
I want to add that if someone programs the internal sounds amp env maximum level at 55 value the distortion will stop when multiple keys are pressed down. Although the sound volume level will fall quite a lot.
Regards

I also have checked a CZ-5000 service manual which states that the DAC offset voltage value must be around 300mV. The problem is that I can not figure out why I'm read this hi voltage value (2.5v). The VR2 trimmer  doesn't do anything. Please share any additional thoughts.
