Hi Worth,
I think you are making the right decision holding back. It's a lot of money to spend if you're not sure.
What I do find a little sad is that any potential purchaser of the PA4X who decides to look through this Forum will surely change their minds on reading most of the threads.
For me, (basically a 60+ novice standard, home player) I find this keyboard a breath of fresh air over my old Tyros 5 (76). The sounds are stunning (in my opinion). The strings alone were worth changing keyboards. I find all the e.pianos a great improvement over the T5, the only one I regularly used on my T5 was called 'Magnetics' which was in the legacy folder. Even the organ drawbars and the leslie sim on the PA4X are much better than the T5 (It's a shame I can only get drawbars on either upper or lower at any one time) and the concept of the leslie sim included in organ sounds and activated by keyboard pressure......utterly dreadful. What the hell were Korg thinking when they designed that.
The main piano sound on the PA4X is stunning (in my opinion). On the Yamaha Forums, the main piano sample on the Tyros 5 is widely accepted as being very poor by owners. It did'nt do much for me.
I certainly won't defend Korg for the O/S issues for the more advanced features on the PA4X, but in the nine months I have owned the keyboard I have not encountered a single problem with it myself. I'm sure there are others like me who are very happy with their keyboards.
Two other points I would like to make, firstly this issue regarding the lack of styles on Korg keyboards compared to Yamaha. If anybody takes the time out to go to Dopamines site (link bottom of post) and download Set 2.6. they will get an additional 1200 styles, 1400 sounds, 760 pads and 320 performances, all loaded into the user sections in addition to the factory set. There is no Yamaha site anywhere where you can download this many styles and sounds in one file for free. I invite all Forum members to prove me wrong on that one.
Finally, price point. My Tyros 5 cost me £1,000 more than my PA4X (61).
When I decided to change, I was able to sell my Tyros 5 privately and with the money I received for it purchase a brand new PA4X with a three year guarantee. At the time, the PA4X was closer in price to the Yamaha PSR-S970 than it was to the Tyros 5.
I do understand a lot of owners are very unhappy with the O/S issues and Korg need to address that (or at least make owners aware they are trying to address the issues), but there are a lot of good things about the PA4X
(at least for some owners anyway) !!!
