East/West Pianos Gold and Sonar X3

PC, Windows 7 Ultimate, Intel Core 2 CPU, 8 GB RAM, 64 bit
 
There is a slider on the East/West PLAY module for the pianos which 'opens' the lid on the piano. This not only modulates the volume, but also changes the quality of the sound--much like a mute on a trumpet. When I use the piano VST, the default position of the slider is closed. I can change the position as the piece is playing and it works. However, when I restart the piece, the sound goes back to the closed position even though the PLAY module looks like the slider is in the new position I moved it to, and just clicking on the slider will change the sound back to where I want it.
 
I have tried to get help from Quantum Leap/ East/West, but so far they aren't answering. Anybody else run into this? Is it a Sonar or a QL problem? I haven't run into any other instrument problems from East/West and Sonar, but I have barely scratched the surface with what I have.
 
Thanks
