Aside from the limiter the included PC modules cover all that but in your OP you tossed in a ton of synths, VST's and other gack that you specifically want. That does not a stripped down version make. I don't really want TTS or some of that other stuff but you do. See where this turns into a problem.
A stripped down version should be a stripped down version. Not a stripped down version plus "everything I personally like".
As far as the loops and stuff... those are kind of just there. I don't think they cost Cake anything at this point and aren't really making them any money. They just offer them to you if you want and they are easily ignored. It's just something cool to play around with if you are so inclined. I actually used them to make my first song with X1 to learn my way around a little. Now I can make my own loops.
For me Sonar could had less FX plugins than what i mention in the first post
just a basic good Compressor, Eq , Limiter, Reverb and Delay, that would be good.
For the Synths, i could get rid of all, if Cakewalk could manage to bring along
a great GM VSTi , that would be more then enough.
That is stripped down, and i really would like that.
