Bc2000 (for the BCF2000 & BCR2000)

Hey guys,

           Do the led's around the rotary knobs indicate the current
midi setting of the note\parameter that the unit is programmed it to
control or just the position of the rotary controller? I've been
searching around for a day or so to try and get a feel if this is so.
I want to control a few amp and fx parameters in Guitar Rig. All I
want to do is to be able to move the eqs + drive around at rehersal. I
don't want it to jump drastically as soon as I touch it (I had POD2.0
that would do that) just add or subtract from the current settings of
the GR patch. Knowing where I'm at would be really cool. Can I use a
BCR or do I have to get the motorized slider version. 

Thanks
Paul
