Hi,
I am using a Nektar Impact LX61 with Sonar Platinum. The Nektar NP2 sustain pedal works as expected with pianos in Dimension Pro but not with Rapture Pro. Any thoughts, suggestions, etc.? Thanks for any help.

Try setting the channel on the track to "1. Rapture Pro"

I'm not recording a track - I'm using Rapture Pro as a standalone on my PC. When I open Dimension Pro as a standalone the Nektar sustain pedal works perfectly but with Rapture it does nothing. I was hoping there was something in Rapture that I needed to set up. I did go to the "instrument" tab and added midi control "sustain" (cc64) and when I press the pedal the macro knob goes from 0 to 100% but still nothing. I'm sure that there is something that I'm missing but I'm not familiar with midi at all.

Io be clear, you are using the same program on both synths.

I tried the same Dim Pro piano patches in Dim Pro and Rapture Pro.  I also tried a number of other Rapture Pro piano, organ, synth and bass patches. Every single one of them honored my Nektar sustain pedal on my P6. I was surprised when it worked on the synth patches, to be honest.
 
So? NTF.

It works fine when I'm in Platinum and set MIDI channel to "1: Rapture Pro" but not when I'm using Rapture as a standalone.

Sorry I forgot to mention. All of my tests were with the standalone Dim Pro and Rap Pro apps.
