yes I do use it.... mostly some times I get lazy and want to open pt to edit and don't feel like hooking up my 11r.... when I used my mac, pt used the internal hardware anytime the 11r was not connected and I wanted to do that with my pc and that is how you do it.

it just makes Pt see your comp sound card as an audio interface.

it doesn't hurt to try it.
