Been testing these keyboards over the last few weeks...

And i came to the following conclusions.... (Excluding vocal harmony as thta is of no interest to me)

Soundwise, the PA600, PA900 and PA3x are very close, they use the same engine and mostly the same samples for most of its sounds... The topmodels only have a few more sounds, same goes for the effects they are mostly the same, only the PA3x has a few more.. But nothing spectacular...
And when you look at the arranger features, they are pretty much the same for all 3 Korg models..


With Yamaha on the other hand, only PSR S750 and S950 are very close, but all the main features of the T5 .... SA2 voices, Organ world, upgraded effects section, ensemble voices... Are not available on the lower models, and the only difference between the S950 and the S750 is audio styles...


In the end i came to the conclusion the PSR S750 and PA600 are soundwise very much comparable with eachother, sometimes yamaha wins, and sometimes Korg wins, but when you compare the T5 sound with the PA3x ( i owned both) the T5 is far ahead.. However the strength of the Pa3x is in its edditing and tweaking..

With any of these keyboards you have a great sound, and the difference is in the details... But i cam to the conclusion that Korg is at least the equall to Yamaha soundwise in the lower models ( both have their strengths, i think the difference here might just be personal prfference, but when playing either of them, you will not notice much quallity difference, both sound inbetween good and great) but Korg is a clear winner in that cattegory when it comes to features...

So, this leaves me wondering if Korg can catch up to Yamha's topmodel with an upcomming Pa4x, which is due early 2015.
