No, those are audio tracks.
Tell your studio to install East West Hollywood strings, load up 118 samples and try and run them. You will need 50+ gigs of ram, and probably have bottle necks so you would need a slave anyways.
Any film scoring template will absolutely eat up a recording session, most engineers won't fathom or believe this, unless it's the engineers at Native Instruments, Vienna, East West, etc.
Also, Pro Tools can't use more than 4 gigs of ram, or a little more, so if the studios computer is using all 6 gigs of ram then it's happening outside of Pro Tools.
