Hi BradMZ,
The problem seems to have worked itself out. Turned the unit off and on a couple of times and played on different solo synth settings while on. The last time I turned it on it was in the default setting so I tried it out and no stuck notes. This keyboard sat idle for about 6 months while I did other things musically so maybe it just needed to be "exercised" again to work the bug out. If I have any future problems I will certainly let you know. Also, I haven't downloaded the upgraded firmware yet either(still running on version1.0). I have been told by someone at Casio the easiest way to do this is after I've downloaded the upgraded firmware to put it on a data card and upload it to the keyboard via the data card. Do you agree with this?
Thanks,
WOODSYNTH
