You may need to go through some remapping exercises to find some acceptable substitutes on the T2 or back to your original question about samples. Look at the
From what I have read the T2 is somewhat OK in reading samples but it is not its strength. I think it will be a case-by-case basis of when you will have success. One thing I know it does not do is beat matching for tempo changes when using loops. It does support AIFF and WAV formats. However, I have seen posts from time to time with people having problems loading some AIFF samples. Sorry I don't have more concrete info for you about samples on the T2.
As for the sounds on the T2 if you look at page 18 on the T2 data list http://www2.yamaha.co.jp/manual/pdf/emi/english/port/tyros2_en2.pdf
you will see a listing of what sounds are in the Arabic drum kit. Page 7 is the GM ethnic group.
The below link is to a post where George Kaye, a knowledgeable keyboard dealing in CA, stated that Yamaha is working on a full conversion of the A1000 for the T2. Perhaps they will work on upgraded sounds as well. http://www.synthzone.com/ubbs/Forum37/HTML/013293.html
