This brings up a good point:
To Cakewalk: You should make the Pro-Channel a standalone plug-in shell. Make it plug-able into ANY DAW, not just Sonar, even it it has to "float" just like any other plug-in. Turn it into a better Plug-In chain for other DAW's as well. Not everyone will be using Sonar for various reasons, so this would be a great advertisement. This would allow your own plug-ins to be used with and DAW, getting you in that game, and when people love the Pro-Channel use in other DAW's, then see how well it sits in Sonar, they'll consider this bonus when looking to switch to a new DAW.
