you can actually access the settings as they were on the old prophecy through a funky combination of the back buttons when you turn it on, but as you said it should work straight out the box. so really it's only made to be accessed when there is a fault.I wasnt aware you could adjust anything on the z2. It was marketed as a fully automatic loader, as in does everything automatically for you, like unjamming a jam. Just switch on and go.
Are there dip switches on the board or something?
