Route system audio into cantabile

Hi there, new user and member to the forum. I am looking for assistance with the below:

How would I go about routing my system audio (which can include anything from web audio to DAW etc…) into cantabile?
I would like to use cantabile purely as a VSThost for my spectrum analyzers mainly instead of having them in the master bus of my DAW.

Not sure if it would help, but I am using the below:

  • DAW = Ableton Live
  • Audio interface = Focusrite scarlet 6i6

Thanks for any assistance.
