Zuki your very welcome glad to hear your doing good this "second time around" ....
I still really like the Pa800 & its very cool features....but I really wish there were many more styles to choose from....trying to convert Yammy/Rol/Ketron were difficult at best and not very good. I just needed much more to choose from & Yamaha provides that & more for me with Roland, & Ketron right behind. I also wish the file system OS was better too. Anyway I can wait a few months till the next wave of arrangers passes through & see what will be released next. Next month I will also try the TC Helicon Harmony M unit

I hope its on par with the VH in the Korg as well we'll see.

stay well and good luck.
