EXS 24 Logic Sampler Users Group

Hey group, I recently purchased a Midiman Radium to serve as my main
midi controller.  However, i have been having a problem programming
the sliders and knobs to work with the EXS in LOGIC 5.5 on OSX.  I was
able to get the knobs or sliders to work with volume, pan and
modulation only.  it seems the radium manual had their own assignable
functions to the CC#s and the EXS24 manual had its own.  So i'm
COMPLETELY confused.  Perhaps there's something i need to tweak in the
Preferences?  I installed the drivers like the manual says and that
was it.  So maybe i missed something. Hope you guys can help.  

Thanks a bunch,

Henry
