I found this one which fits all Priva models. For the PX5S you have to remove the blue plastic strip and insert the music stand http://www.keyboardstoday.com/Merchant2/merchant.mv?Screen=PROD&Product_Code=MusicHolder+19+3%2F8+size&Category_Code=MH&Store_Code=CK
Hello, I just bought my PX5S and need to place my music sheets somewhere for playing. I have seen plastic shelves attached to Casio home pianos. Is there a simple attachment that I can get for my keyboard or even reuse one for another piano? Thanks in advance and I am really happy with my keyboard even in 2017.
