This is all well and good to say the merchants put their best foot forward and not to expect the same when you open it up. You must ask yourself in what area is yours deficient. I assume they cherry pick songs to demo,maybe tweek the sounds;maybe not. Some demonstrators are very good,playing their best stuff. If one is disappointed,is it because you can't play like them on their chosen songs?-A little unrealistic.
We are all somewhat the same,but different. Donny is very picky,and that's not a put down. I look at basic sound,features,and reliability,with the idea of OOTB is as bad as it can get,and up from there.
With this said,I have never been so delighted with the sound of a keyboard as I have with the SX900,since my old Audya days. Everything is balanced with the thought that most customers are not going deep into the machine,and that's good,because that is Korg territory. The effects and styles,to me, are great. Nuff said
