Well these styles are for owners of instruments other than the Audya however, discussing Audya owners; there are still a large number of entertainers over here that find it difficult to make the transition to the Audya because they have a set program and rely on certain styles, so for those people it makes the process so much easier as they can switch over gradually.
There are also those who have brought an Audya simply because their old equipment has worn out, being forced to change and are too set in their ways to move to Audio styles
For me, I like to use the best legacy styles by swapping out the Midi guitars and drums for live ones, re-balancing and changing voicing to make new Audio styles.
