I'm a new Pa50 owner and just wanted to know if there are any diffrences in styles and sounds between the different verisons of the Pa50? I guess you call em OS1/OS2/OS3. If not what are the major difference than?

Hi Kangal,

I bought a PA50 a few months ago and it had V1.04 dated 2004. One thing i did notice was how long it took to load the OS (>30 secs). So i updated it to V1.05 dated October 2005 and the first thing i noticed was how quick it loaded the OS, less than 10 secs. So theres one major difference. It also cured problems of keys not sounding esp. in the right hand. I probably think that problems like that are due to polyphony i.e. how many notes the keyboard can play at any one time. This can depend on how 'full' sounding styles are. I've had this problem when i used styles converted from Yamaha, Roland and Ketron. I'm not sure about V1.03 sorry.Usually a pain in the a** cos its the first version of the OS (':lol:'). A word of caution though, Kangal, MAKE sure you save anything you have in USER memories, styles, programs etc to floppy before you decide to update the PA50's OS. I didn't and lost countless hours of programming

Oh and by the way you should format the floppy in the PA50 itself not a PC before you download the OS from Korgpa.com. The ZIP file tells you how its done.
It tells you to load the musical resources too after updating the OS. I didn't bother and works just as good.
Be patient it takes time.
If you need any more help just ask

Hello everyone,

You're talking about a 1.05 version of the OS of the PA50 ?? I have the 1.04 and it seems to be the lastest version according to korgpa.com. Where did you find such a version ?

Thanks

I too am looking for the Os 1.05 as well but I have not found anything yet. Can someone please guide me as to where I can find it from? THank you!

Okay just to confirm, the version 1.04 is THE LATEST OS for the Korg pa50. There is no version 1.05 at the moment.....I have confirmed this with Korg USA and I have looked everywhere on the internet as well......
