Couple observations. 1. RTI has drivers that will control the mca series product, and they offer an application to control if you don't want to use the FREE Russound application. The RTI would allow you to control the Russound as well as other devices if that's your goal. 2. Have you talked to someone at Demopad about what you're trying to do.

I've been in the trade for awhile, and I'm not familiar with Demopad, so have no idea as to how responsive they might be.
