Gary, yes, that connection you speak of on the back of the breakout black box is indeed LINE INPUT 3.
That cable you showed me I have not seen before. That appears to be EXACTLY WHAT I NEED! And THAT will give me stereo piano recording, right ??

I did check the windows RECORDING CONTROL and I am able to activate a LINE INPUT 3.

I still have NOT found the CREATIVE MIXER! If I use the setup described by you, Gary, DO I need the ASIO drivers or do I stick with MME?

Thanks.
