IS there way to skip some processes?
More precisely I need to totally skip some HDA sometimes, I put switch node after the HDA processor and set 1 if I want to skip it, but it firstly evaluate if HDA processor needs to be cooked or not, and after this it looks at switch node, so it does not work first time when your run, only second time

I found the solution. Every top node has schedule when in scheduler tab. if you set 0 there, it is skipped.
