We went to check on the download of OAX 2.5.x this morning and found something new (but not the OAX update).
When implementing the OAS styles in the OAX system, some older real-drum styles were not adopted. Now, these are available here for you to download free of charge:
After the download, you have to unzip the file! Then load the styles on a stick. For the Styles-Import into your instrument, you have to follow chapter 7.5 resp. 8.8.5 of the manual.
Gotta say, not too sure we know what this is all about – anyone?
