I would check out the legal standing of Kurzweil before thinking of doing a purchace from them, I heard from a friend that works in the music biz, that even the dealer could not get a power adaptor from them because they could not answer the phones, and the other, is because they use a very stange voltage, so if it breaks, you can NOT get one right of way, no to many dealers stock this item, so becareful.
As far concern the arraenger, I would recomend to do a search of what type of styles are you going to use, and I would take it from there....
