Hi Jørgen
I thought it was German, but for some reason Alta Vista did not translate. I remembered you were from Denmark, so I thought it might be Danish too. On the weight, as George reminds me, the PSR9000Pro is based on the Yamaha EX5 which weights 44 pounds.
Scott may have missed some of the specs I presented in my post to him in another thread. The Pro has 50% more sample ROM, much of which is dedicated to a new grand piano, I believe. George mentioned the plug-in cards. They do provide extra polyphony, but this is almost negligible (1 voice with VL, 5 with AN, where the Pro starts with 128). (These are the main cards people will want.), I am hoping that if you add a vocal harmony board, it can be used to process home grown vocal samples ala Variphrase. The Pro has sockets for two "swan neck" or goose-neck lamps! Someone once mentioned something about enhanced style capacity or improved styles, but I have not seen any confirmation of that.
Afterthought: Currently, the added polyphony does not seem very valuable. Of course, it may become more valuable as Yamaha comes up with more advanced plug-in cards.
