I`ve read the manual and need to confirm a fundamental feature before buying. I have a small home studio with a good newer PC.  But the motherboard doesn't have native thunderbolt and I want to replace my older USB interface with a PCIe card if possible. I monitor strictly through headphones, but need two line inputs and outputs for my small setup. The manual and description keep referring to the stereo analog ins and outs, which may simply be referring to the fact that it is two ins and two outs (rather than a stereo signal that cannot be two mono inputs and outputs).  The two options for analog breakout cable clearly show two individual analog inputs and two individual analog outputs (either balanced or unbalanced). I am hoping that these function as traditional line inputs (outputs), so I can use them separately for two mono analog inputs (e.g., two mono synths, two separate mic pre line inputs, a single mono guitar line input from a two notes torpedo etc), or in stereo using a L+R line output from a stereo synth or digital piano.  I use Studio One and would expect to see the two analog inputs (outputs) as two separate inputs (outputs) along with the adat, AES inputs (outputs) etc. I have never used total mix, so not sure if setting the two analog inputs as either stereo or two mono is done in TM or Studio One.  Thanks.
