I have downloaded this patch, which is for the Privia PX-5S (http://www.casiomusicforums.com/index.php?/files/file/71-9-layer-organ/). I wondered if I would experience any problem if I load it on my XW-P1... Note: It has the same of the many extensions (.ZPF) the XW-P1 uses. Also, does the same apply on the other PX-5S patches? Thanks in advance!!!
