I have to agree with Linda. This is not a WK. The MZX-500 is basically the PX560 with four variations, sampling, and performance pads. The OS between them is almost identical. It's almost like they didn't take into account the coding for the additional variations. The mixer issue problem is across the board. Even in normal play.., mixer settings made to style parts applies momentarily. You can make the adjustments, but as soon as you move to another variation, or even hit the fill.., everything resets. This is a serious Mixer issue across that board that pertains to the styles that needs fixed.

I also remember seeing a post from another user about the sustain pedal not recording in the style/pattern recorder. For me the mixer is a huge problem.., as I imagine it would be for anyone who plans on using this board to create music. Even if you don't take the mixer issue with recording in both the style and midi sequencer..., not being able to adjust basic mixer settings (and have them retained) under normal style play will certainly be an issue for many.

Right out of the box the first thing I felt needed done to just about every style I used was that they are over saturated with reverb. However.., I can't even get the reverb adjustments to work in normal style play mode.

Casio needs to step it up. This board is supposed to be a big move for them. The original MZ-2000 had an uphill battle. They market the new MZX with all these production tools, but fail to code the most basic features properly.
