Hi,
I've a Pa1X that anyway it's compatible with Pa800 (similar style format).
I've tried several conversion and I frankly believe that it's worth considering only if you have a strict amount of styles that you really need and would like to have.
Conversion is not painless, there are several issues involved, and anyway I'm not with those guys saying "I've 2000 styles converted from xxxx": 99% they sounds horrible. A lot of tweaking must be done in the keyboard like adapting drums, articulations, effects that are proprietary for each brand.
Don't get me wrong: it's a good experience, very formative, but there is some work to do, no question. At the end you will appreciate much more the style and find yourself "richer".
Hope this help.
Regards.
