HI! Everyone. I want to ask all of you that how can I install .ZLT flies into my Casio PX-5S, because when I was dragging flies into the Data Folder of PX-5S editor. The editor didn't detect that flies which is .ZLT. How can I do for this problem?

Dear all friends I want to ask all of you that do anyone have the FM (DX) Electric Piano Presets for Casio PX-5S? Because I want to use FM tones with PX-5S in the Worship and other reticals. Thanks
