RE: AAS - Rapture Pro, plugins live?
All AAS virtual instruments, as well as Rapture Pro, come with standalone players, so you don't need to load SONAR to play them. Works great for live playing.
I use a program called Gig Performer, which lets me build 'racks' of different virtual instruments (VSTs) with defined presets, and switch between them live. Love GP! http://www.gigperformer.com/
