Hi! I have an XW-P1 and a WK 6500. XW-P1 has a button called "Hold" which works as a sustain pedal, so, when you play a note it mantains playin forever whith sounds like sax or trumpet and ends playing later when piano sounds are selected. I really like it, couse it makes sounds feel really fat and expresive. Does exists this function in WK 6500? Pianos of WK 6500 die really fast, making some songs sound rare. I know it can be solved with a sustain pedal but I prefer a function to simulate it's allways holded.
