No other arranger manufacturer does this. Believe it or not, Ketron released an OS update for the Audya that no longer allows the use of 3rd party styles on it. Only styles packaged by Ketron direct can play on the units with the new OS.

I have NEVER experienced anything like this. To work around it, one has to try to locate another version of the OS, which is not available anywhere except those lucky enough to get it before it was removed. It seems as if it is not at all available for certain Audya models.

Knowing Ketron, this does not bother them at all. So, something to keep in mind & to be on the lookout for when considering purchasing an Audya unit.
