EXS 24 Logic Sampler Users Group

I have an acquaintance who has fiddled around with a MIDI keyboard with 
built in sounds, "tracks" etc. and now she would like to step up a bit 
to a DAW. I would like to suggest the Logic Audio Big Box to her which, 
if I recall correctly, includes the EXSP24 software.

One question though...

Is the essential difference between the EXSP and the full on EXS that 
you can create and map your own sample sets with the latter, whereas the 
former is simply a sample player? More specifically, if she uses the 
EXSP24, she can compose/play multiple tracks of MIDI and route the 
signal to be recorded as audio if she likes, correct?

Many thanks
