I just noticed that one of the styles on the disk was rubbish. Some of the others had phrases or pads that were too involved and didn't sound right with chord changes. I found that when I reassembled these with PSR2000's Style Creator using internal styles, I was able to get very good results with a few of these styles. I used one of the styles for "Put on a Happy Face" at one of the retirement homes I worked at today, and I got a great response.
Thanks Simon for the FYI with those Top Trax.
