Well, I don't own the SD9 Pro and never owned the Audya but I do own two SD7s. Henni's styles have never converted to my SD7. I downloaded thousands of the Ketron legacy styles and about 98% of them converted and played with no issues at all. There were some that would not convert and some that frooze the SD7 and it had to be rebooted. I did not see this as a real problem but others do. I gig with the SD7s almost daily and have yet to encounter a problem on a gig. But, I don't "experiment" on gigs and know the styles, mp3s, or midi files will all play when needed.
