EXS 24 Logic Sampler Users Group

I have Logic 5.5.0 with Mac OS 9.2 (could go to OS X but eMagic says this is
not useful for my applications). I'm trying to import a Giga format sample.
Unfortunately, the sample I care about (which represents the majority) is
formatted for PC on the CD (i.e. the disk itself), not for the Mac. The .wav
files which comprise the overall big file are importable into EXS. In this
particular case (from EastWest at Soundsonline), the disk is .rar compressed
into an .exe file which fits on a CD -- the uncompressed file would not. I
don't have access to a PC at my site.

Here's what I've done:
1. Offsite uncompress the .exe file onto a PC. It ends up as one large .gig
file.
2. Move .gig file to Mac offsite. Again one large .gig file (~900 MB).
3. Use Stuffit to compress .gig file into a .sit file which fits onto a CD.
Burn the CD.
4. Take the CD to my site and uncompress. It does uncompress but I get
"error 17538".
5. Import the file into EXS by moving the .gig file into the samples folder.
Logic thru EXS does in fact recognize the .gig file, creates an .exs file,
and moves 12, but only 12, of the
528 files (or is it 529? one file is in "default") gets converted to .wav.

The end result is that if I have the pedal down and play pp (not mf or ff),
I can hear some "A"s and "B-flat"s and nothing else. So I think I'm
partially there and the technique fundamentally works. I'd like to believe,
though, that there is a better way.

Has anyone gone through this before? Any tips, suggestions, etc.? Any ideas
on what it will take for the Giga format samples producers to recognize Mac
as important or for eMagic itself to supply tested procedures for importing
a supported format (Giga) which exists mainly on PC disks into the Logic
application, which is, going forward, being supported on Mac only?

Thanks,
Larry
