First, thank you very much for keep an eye at Yamaha Musicians Forum, and repost what you find here. 👍

As you see, the Factory styles is from discontinued older models.
It's already shared by many at the web, also at the ORIGINAL PSR Tutorial, but as you see in my posts, this is information written in the posts.

You're right, it is helpful to have links to commersial sites that sell QUALITY styles and software listed in one post. Easy for those who want to explore, just copy and paste into browser.
Maybe I did a mistake by place PSR Styles there, the other sites don't sell 18000 whatever it is collected from the web. They sell own creations and also products on behalf of other producers.

There is also a lot of sites that sell 'compilations', most of it is more or less messed up and useless rubbish. Those who want such stuff will easily find it by do a Google search.
Been there, done that and learned my lesson.

Thank's again for repost here at SZ. 👍
