AnarchikNYC1: I have done several Jewish gigs (parties and services) using the T2. I have found it to be quite versatile for this purpose. I did not have a library of middle-eastern/oriental (aka oriental) sounds/styles to use as samples for the T2. However, I found a variety of oriental styles on various web sites. Particularly useful was the archive of the yahoo PSR-Styles group.

I was able to find a variety of styles that I has able to adapt. There was a Yamaha keyboard, the A1000, that is no longer available that had a variety of Oriental styles. Many of these styles and others can be found on the above listed site.

There was a rumor that Yamaha was going to make the A1000 style/sound set available specifically for the T2. However, I haven't heard anything about that since and have found lots of good material as noted above.
