Hi Salman
I wonder why you have used Music Soft downloader to load a style into your PSR E473, rather than simply importing the style directly to the keyboard using Yamahas built in software on your keyboard?
Pretty well all recent and previous styles can be used by following the steps detailed on Page 28 of the
REFERENCE Manual for which I have downloaded a link below for you.
Please note that this is NOT the User Manual that you will have received with your keyboard. Styles must be in the. Sty format to work, but bear in mind that some styles may simply be incompatible with your keyboard, or the particular file may be corrupted in some way preventing it from being used.
Try loading files as described, and I'm sure you'll have no further issues.
