I recently updated my px560 firmware to 1.14 in order to fix my the pedal issue. the update made no difference to its operation.
My pedal is the Korg exp2. I have calibrated it according to the casio mans video instructions on youtube.
When using this pedal the change is sudden when pressing down a little and there is no smooth control over the range. I Have tried other ways of calibrating all to no avail.
Does anyone else with the latest firmware have this problem or could it be that the korg exp2 is not compatIble.
Since updating the firmware I have had the system crash on a few occasions (only recoverable by pulling the plug as the on off button wont respond when it in this state).
Overall I find this keyboard very pleasing and sounds excellent. (even using its own speakers).
