Hi all! Bought a WK-7600 a month ago, and I'm a PSR 730 and PSR-S700 owner. I want to sell them and stick with WK only, but there are some rhythms on S700 that I want on WK... Is there a way to convert them to AC7 format? Seems that all existing software available is obsolete, and somewhat hard to find. Got IDES 4 and Data Manager already. Got some rhythms from music.casio.com (CKF files)... Anyone knows a way on how to accomplish that? Thank you in advance.
