I haven't downloaded any sound libraries, yet. Probably won't either, but if that sound was worth it, I'd download it of course!
Anyway, here's my choir patch. You need a reverb, though! Plays best from C3 to C7. Due to the nature of the filter, though, "AH" (modwheel up) will be weak in the lows and overall a bit quieter.
I hope, you like the patch.
