ccdmax . . . Wow MAN!, you're one lucky dog alright. Your keyboard choices are exactly the idea combo I'd love to have, but unfortunately, I can only 1/2 afford it so far. The marriage of the Tyros2 and Korg PA1XPro provides you the BEST of both KORG and YAMAHA worlds, and imo, the best sounding arrangers on the market today, with the competition trailing them. As far as the learning curve goes, since you're already familiar with both the Korg & Yamaha OS, you should have no trouble just getting down & having fun 'making music' right away. Looking forward to your on hands review and MP3 songs recorded by you with your braned new toys as well. - Scott
