It is not possible as far as I understood.
My friend gives me some TR files (Sounds really good on TR). No way to try on my PA 600. The problem is, it is really hard to get good quality PCM Drum kits (Tabala or any sound) somehow you get a good one then it is not compatible. Really disappointing.
At the same time Yamaha, even Tyros 5 styles can be used on a low range PSR. That is flexibility.
Korg should provide at least a good software to do such conversions.
