Hi,
it looks like the styles you've uploaded might not be fully compatible with Audya patterns. It happens, even though Audya reads a lot of Ketron .pat formats.
My advice is to use the EMC style converter, and do a proper conversion, transforming those files into SD1 or XD9 formats, so you can be sure it'll accept them and play them adequately.
Cheers!
