EXS 24 Logic Sampler Users Group

I just purchased a samples of giga instruments and they are amazing but I have a 
question. My understanding is that all of the parameters of the gigasampler format 
"can" be translated but does anyone know which ones have been translated so far?

I've heard that some of the following may not be converted yet:

1) mod wheel control
2) velocity switching which uses the a,b,c,d crossfade parameters

thanks,

greg

p.s. this is in reference to Logic Platinum 5.4 (OSX) version
