I don't see the importance of the Piano when your gonna play it "in a mix" with a styles etc,......yes a good piano is needed to a point,.....
but, if I wanted a PIANO I'd Buy a Piano of some kind to play solo.
But we all have our preferences,.....it's just that Piano was never mine.
Good luck.
If we were good piano players,,,we would understand the importance of a great piano sound and key response..
Personally, I want the best piano sound and key feel, the arranger can offer..I do play piano mode, when I play styles..
It is the sound I demo first..If the company doesn't do a good job on piano...not interested in the other inferior sounds...
It all depends on your playing style how important the piano is. I play a lot of piano with minimalistic acompaniment which makes the solo piano sound and keybed feel quite important for me. Thats the main reason i have an 88 key Kronos under my T5..
The Yamaha grand piano on the T5 is between good and very good when used in the mix. But when used solo its about just okay. Solo piano just requires more dynamics and depth then playing it in the mix. Thats why Donny has other needs for a piano then me and Fran.
The Kronos German grand in the Kronos is about 4Gb and the version in the Krome is 2GB. The PCM sounds of the PA4x total 5.1 GB, which makes makes the version of the Krome the most likely one to be used in the PA4x. It could even be a 1GB version of that Piano, all depends on how they loop the samples and such. but in both these cases it allows for having over 3GB of other PCm samples for all the other sounds which still is huge.
According to the German Korg webside, the PA4x has the streaming engine of Kronos build in, just looks like its not available for user sounds yet. Seems User sounds can only be loaded into RAM. which is a pitty. there is also the limit of 500 user voices max. which really reducess the usefullness of the PA4x compared to Kronos, you just cant have an entire libraray of your very own sounds which would hyave allowed to build your own library
There are also supposed to be localised versions like the Musikant, Asyrian, Balkan and Indian versions. Which have more (1800+) sounds then the 1500 base sounds of the international version. and still have the 400 MB user sample size..
Korg needs to be more open about their future plans, hardware expansionsand updates for the instrument whne they want to make it a huge hit and rival the T5.
In general people that dont want all the expandabillity and user sounds are probably better off with a lower tier model. To ma Korg has allways been about creating your very own sound on top of having great sounds out of the Box. So it requires more then just a great piano espescially where it comes to adding your own sounds and samples.. Having more then just one grate piano sound in the future is what sells a korg...
