This is a Comparison Chart that I've compiled for the differences in style Banks for the pa700, pa1000 & pa4x.
Hopefully it's accurate but any discrepencies can soon be rectified using Microsoft Excel
This is most of the styles from all 3 pa keyboards latest models as in the comparison list above
A fellow Enthusiast of Korg Duby2 on Korg Forums uploaded the extra styles that are available for the pa4x and pa1000 that are not on the pa700. They were compatible with the pa700 but could not be accessed by the excellent new feature of Direct Access to files from USB/Card Reader. I decided to work on them them so that they could be loaded directly from Direct Access instead of loading them into User Banks thus leaving User Banks for all the many Custom styles that I possess.
Incidentally you can actually copy them to the pa system Disk and use Direct Access to them from there so not needing to load from usb.
