Great keyboard, but I have a problem! Split Point
MY problem is the SPLIT, it has been good up until yesterday, but now NO MATTER WHERE I SET THE SPLIT POINT, there is a noise something similar to an accordion bellows shake that overwhelms anything I try to play. The noise is like a number of keys being played at the some time, out of key with a strong vibrato.
This happens only below the split point, by moving the split point to the bottom key, I can play the rest of the keys okay.
