EXS 24 Logic Sampler Users Group

I pretty new to the EXS, and have been absolutely loving it so far, but I
have been having a problem with a couple of gigasampler format CD's that I
just bought.  They are the Malsmjo Grand piano and they are 1.9 gigs once
they are decompressed, but they are in two big gig files, so I put them into
the same folder on my hardrive and I made an alias of the folder and dragged
it to my sampler instruments folder in my Emagic folder.  I then went into
the EXS and opened the first and then the second gig file.  It seemed to
have converted it to EXS format fine, I saw each audio file get converted,
but after it completed I was only able to access the first few octaves of
the piano.  I don't get it???  Do I have to use the editor to do any
mapping??? I don't have a lot of experience with sampling so I don't know
much about mapping.

Please can someone help me?
Thanks,
Jason
