The description on the download page should indicate whether the files are SFF1 or SFF2, as well as- in the case of SFF1 files- whether they're 4-variation or 2-variation styles.

If you want to try some external files with your friend's keyboard, I think there are several SFF1 files available on the main PSR Tutorial page- probably under the PSR-730 or something similar. Regarding the styles, it isn't the 4 variations that are the problem- you can use 4-variation styles on the PSR-E models as long as they're SFF1 files. If you don't have a copy of the Owner's Manual then you shouldn't be expected to know that, unless you had prior experience with a PSR-E model. You can use Jorgen Sorensen's utilities to convert from SFF2 to SFF1, to remove any unusable sections, and to edit the voices.ĭon't worry about the CATEGORY buttons- I frequently try to use the '+' and '-' keys on the number keypad to navigate through the Function menu on my PSR-E models, then remember (after it doesn't work) that I should be using the CATEGORY buttons instead. In any case, I doubt if you've damaged the keyboard's memory, but you definitely want to follow proper safety precautions about inserting and removing USB sticks, as well as not turning off the keyboard while it's writing data. Of course, the voices and effects in the style will probably need to be adjusted to select ones that are available on the PSR-E453. There might be other possible issues, but I think those are the two to watch out for.

If the style file you'd saved is larger than about 50K, you'll need to see if there's any way to reduce its size, such as by removing any sections that aren't usable, such as the C and D variations of the different sections. (2) There is a size limit of approximately 50K (IIRC)- the exact number of bytes varies from model to model based on the size of its system memory and how much of that space is allocated for various things, such as the registrations. (1) Only SFF1 style files can be used, so if the style file you'd saved is SFF2 you'll need to use a utility to convert it to SFF1. My gut feeling is that it isn't showing the style file you'd saved because that style file isn't usable for one reason or other.
