Yeesss, found it!
I finally tested it, not my style of choir (it is the usual cinematic style) but thanks a lot

No worries. Although their demos are always as large sounding as they can make them. In the plugin all effects can be turned OFF and voices can be used dry which makes them much less intimidating. The plugin is quite accommodating in the fact that one can chose to configure smaller ensembles and either single/mixed gender as well. The only drawback IMO is that it's a really large library...
Anyway, good luck in your search!
