?'s re: receptor

[daif]

hiya- thinkin of gettin receptor and was wondering can you layer 2 different vsti's sounds together? also what kind of sound card is in receptor? any issues with using tranzport(frontier design) with receptor and uniwire? can i use CME UF8 as a controler? looks like this a great product--will it really save on cpu 'cause i'm having some dropout issues in my sonar4 & project5???
thanx
