I have owned my CVP 207 since 2002. Starting this past week when I play certain instruments like the Nylon Guitar, using a split keyboard, the last octave after the split on the left, each key is out of tune. All octavs after the out of tune are fine. I have also noted that it is most noticiable if I use a transpose setting lower than -3. The problem seems to be just with some of the guitars but not all. Other instruments like the Grand Piano work fine and all octaves are in tune no matter what the transpose setting is.
Have anyone experienced this and is there a fix?
