    Have you tried a factory reset?

    That's usually the first step of a diagnositic.

    Your description of "acoustic voice" causes me to think about stretched tuning.....

    http://en.wikipedia.org/wiki/Stretched_tuning

    This youtube has a very good explanation of acoustic piano tuning and the reasons why they are "stretched":

    Check pages 76 and 77 of the CVP-305/303/301 Owner's Manual, about "Changing Pitch," including scale tuning. The CVP-303 has nine preset scale types; there's a table on page 77 that lists them and shows how many cents sharp or flat each note would be if C were used as the base note for the tuning.

    Some brands of keyboard (such as Roland) have an option for stretched tuning, but I don't see that mentioned in the CVP-303 manual.

    I know that on the next model up (the 305) the stretch and flat tuning options are in the voice edit mode. That said I would say as the poster above to make sure to check the scale tuning in case something got messed up. The stretch tuning on my CVP-305 isn't too noticeable except in the last five notes at the top of the keyboard or so.

    If a "factory reset" is the first step in debugging, the second step is:

    . . . Use a "guitar tuner" (or any other chormatic tuner, available free for Android and iPhone)
    . . . to ensure that the note _really is_ out-of-tune.

    Your ears can play funny tricks . . .
