I may be able to offer some assistance.
I have a Cakewalk definition file for a PSR2000. It is based on the one thats available on PSRWorld (I think - I followed the link from another post in this forum) with some adjustments, mostly the inclusion of the drum edit NRPN values and the correction of a few patch names. If you load this definition into Cakewalk you can then drag-and-drop the NRPN lists into your PSR9000 definition and hopefully this will improve things on the drum edit side of things.
I would have posted sooner - but I hadn't finished it!
I haven't got my own website to post it to (in fact I've never really explored the ins-and-outs of posting things to newsgroups or forums so maybe I should learn) so e-mail me and I'll send the ".ins" file back.
