I may not be in the right area for discussion about my PR700 but I can't find any discussion about it anywhere. I love my full sized unit but need to find some guys who use the 88 key models. As a footnote, I tried the kn5000 before buying the $6000 PR, and I loved the KN (haven't tried the kn6000) but I really needed a full 88 keys. It's just that, it seems there isn't much for patches and arrangements for the PR series... and KN patches don't seem to be compatible. Any help about where to find this stuff would be mucho gratis.

What do you mean by patches? I have a PR900 and may be able to help you. The only KN model files that will work with the PR700 is the KN3000. The PR305 is compatible with the KN2000 files. I don't think the KN5000 and KN6000 files will work on the PR700. If you have any more questions mabye I can help.

I have a PR902 and it accepts KN5000 patterns. Unfortunately I upgraded my KN5000 to a KN6000 and now I can't read those patterns. As far as updates, I've never seen any. Apparently with lower volume (production) they don't get the visibility/updating that the KN's do.
