Just a quick note that the 3rd expansion pack for the new Roland FA-06/08 has been released: the EXP 03 is 99% identical to the renowned SRX 09 expansion board 'WORLD': more than 400 terrific ethnic sounds and waveforms ranging from plucked to brass, from Asian to Mexican and a bit of Country. Although the samples date from about 1995-2000, they are highly usable and partly excellent. (The FA has got 2 virtual slots for expansion packs.)
Here's a demo of the SRX 09:
