Hello
I have not try this on the PR SX 900, but, you actually if you change the name of the file of the either style/voice/multipad,etc....there is a number at the end as an example, "GuitarStrum.S631.vce" The part you can change with the file I am up loading, see the Icon you like and just rename the part to .S528.vce and you will see a different Icon. Just make sure you do not delete other information.
The Icons, per say, are already inside the Keyboard.....One note of disclaimer, the file I am putting up, is for the Genos....so, it may have some that may not be available.
I am almost 99% certain that will work, when I made the multipads for the Expansion Packs that is what is been use, the letter with numbers that are in the chart will make the Icon appear. Same thing with the Styles....
