Interesting... I would have never guessed SF's can sound so much different between my SBLive and Audigy - I wonder why this is..?? but your right some sounds are massivly 'aliasing' in my A2 - but not so in the SBLive.. although I still get a bit of aliasing with some patches on some keys (not always on HIGH keys either..??)
Well done either way.
I have some old FM emulations I D/L somewhere 'Vintage Dreams' - IIRC there were 2 - another named 'vdw.sf2' (many samples are single cycle waves) and it doesn't have this same difference between BSLive and my A2.
*opinion to follow*
Theres a place for FM - particularly with the ability to change FM synth params in real time.. .but not possible when emulated with a sample based synth. But I have used em before at times, but all in all - to say this bank 'spanks' the GM sound font that came with my card is a bit of an exaggeratedly sales pitch

* end opinion*
But, pretty cool to add to the arsenal of sounds library.
Thanks for it....
