I am using Rapture, driving that with MIDI. The CAL program "VARYVEL.CAL" actually works. Thanks Scook. I entered the LOW velocity limit and the HIGH velocity limit, and there ya go!! Works.
The Midi Velocity Plugin will not work with a soft synth ... I even tried inserting a MIDI track, sticking the plugin in that, and try to drag it into the Softsynth track. Nope.
