Please Excuse my ignorance...Is it me ? or... here you have a Brand new TOTL Yamaha Tyros arranger keyboard touted with the so called best sounds available SA etc, etc, etc, whatever ....Can some one tell me why you would need to go buy more sounds, TVN or whatever for it after you just spent money on the latest & greatest? ....

What is so lacking that you would need to do this?

Anyone?
