Hello Brad,
I recently acquired a pxs3100. Sounds amazing! The design of the keyboards leaves a lot to be desired. can you all try to be more clear about things.... ie. when you are writing a tech guide... don't just say, "push this button" know that we have pushed the f'n button already probably a hundred time. try to think ahead and offer clear precise information, even if it make Casio look like they haven't been forthright with there information. because if they had many people "professionals" will and and would not have bought it.
