Hi Stephen,
I can hear a difference between my PA800 & My Pa3X when played thru same speaker system. Whether or not styles are just better balanced or they've used better sounds in the styles, I don't know, but to me, listening to the pa800 version of a style, then listening to the pa3x version of the style, they just sound better.
I suppose I could go to the trouble of checking style for style whether they kept identical instruments for PA800 vs PA3X, I must admit I do some nutty things, but even that's a bridge to far for me , haahaa
I remember a few years back, when i bought my ketron sd2, I thought wow, I've all but, got the sounds from my SD1+ keyboard in this tiny box.
( Sd2 was actually same as sd5 soundsource, and I was aware of that)
Sounds are very good , but, until I did a really close analysis, even though a lot of the sounds were very similar to my sd1+ they just didn't have the same quality & depth to them.
Wouldn't have a clue what the spec are of the Korg, maybe the sounds that the PA500 does have are the same as on the PA3X, BUT, it certainly doesn't have all of them, or a lot of the other features. Having a sampler & a harmonizer etc etc must add cost to the unit.
Bill and Rikki,
Thanks for weighing in and letting me know I'm not really off my flippin' rocker.
I'm far from being the level of musician that some are here and my ears are aging but I know I hear a difference in the Pa3x when I play it.
