How do I load these files into EXS24

The first (*.rar, *.r00, r01 etc) are RAR archive format. Use something like MacRar or MacPar - typically when these are installed, you just douleclick on the *.rar file, it will unpack all the parts automatically.

Bin/cue files are disk image files. You should be able to right click on these and select "Open with DismImageMounter" which will mount like as a virtual drive - you can then see the files on them.

This is nothing to do with Logic, they are just various forms of compressed file formats, or disk image formats.

So if you are saying you've already unrarred the archive, then no, you don't need any more unrar utilities.

It sounds like the files contained in the archive are your bin/cue files. Bin/cue is really a disk format more widely used on PC's, Toast will mount them on the Mac, for instance.

cpgz is what happens if you run archive utility on them - it's just compressed the bin file into a cpgz archive - not what you want.

I use Toast to handle these on the Mac - if not, look for another utility to mount bin disk images, or use a PC.

FXP format files are not EXS24 sampler instruments, they are a Cubase/PC format for a particular plugin - your documentation should say what the files are for.

*.exe files are Windows PC programs that are most likely self-extracting archives - you'll need to run these on a PC to extract.

Are you sure this library is purchased is EXS24 compatible? If it is, you should have *.exs files (the instrument files) and the raw samples. If you can't see those, then the library is not in EXS24 format, and can't be easily used, at least without conversion.

Again, check your documentation.

It sounds to me like you have bought the wrong version. They specifically did a Mac native EXS24 version, according to a quick Google search. That's the version you need, and the version you don't have...

I'd contact them...

(You can use the Gigasampler versions, if you have a PC to extract the files, but I'd still contact them...)
