Hi Carl, yes, they are. And all of them now use mega guitar voices which made a huge difference. They are available for download over at the PSRTuturial forum under Henni's style collection.

If you cannot find, I can look for them at home & email to you.

Of course they can even be tweaked more for the T4, but I have no interest in Yamaha's for the moment. They are great, but the Audya surpasses them in just about every way, and especially now that AJ added those AWESOME T4 choir voices to the Audya library!!!

Keep well my friend,
Henni
