Hi,
Referent to :
-second:
registration file is mesage with who you can recell your setings when you madet that registration.So you cant edit style thru registration.Registration just remember where is your style location and all ather global setings when you madet that file.

Yes, it's right, but there's something diferent about Audya's SINGLE REGISTRATIONS diferent to the others keyboards like X1 or SD1. In X1, SD1 the SINGLE REGISTRATIONS "just remember where is your style location and all ather global setings when you madet that file", but from the midjay, midjay PLUS and Audya you can put into the SINGLE REGISTRATION the style, it's easy to test, you can make a SINGLE REGISTRATION with a new style that you make and put the SINGLE REGISTRATION in a different Audya, the SINGLE REGISTRATION sound with the style, (if the other Audya contents all the information about this style like LIVE DRUM, LIVE GUITAR, if not *CORRUPTED STYLE*)and of course if the style contents a USER LIVE DRUM you must to copy this files also.
