For automation of parameters in SX U already got loads of posts.. just look thru...

to use the radium 4 control u need 2 knob what CC number each function is using ... now on yer radium configure each pot 2 send that same CC.

Also on the midi track u are using 2 send midi, etc... 2 yer Vst Synths u need 2 activate monitor and choose the radium as the midi In...

If that doesn't work u need 2 go into the File/ Preferences/Midi Filter/ thru and untick conctrol changes (CC)... also in the midi preferences u need 2 have the midi soft thru activated... But the last tweaks should b automaticly configured the right way so u probably need not worrie!
