By the way, would you like to hear about my concept for the vertical noise monitoring? Ie useful for listening to the deleted info to try and discern if there is still music and you should choose a lower frequency? I think I realized a good way to do it.
I would.

Kevin -

It occurred to me that the best way to obtain inverted copies of the input would be to use cross-coupled line receivers.
Using cross-coupled inputs, both inverted and non-inverted signals are available with identical phase shifts.
This also permits feeding the matrix with unbalanced sources.

With an inverted copy of the Right input available, a differential connection using a 1243 or 1246 allows L+R in the form of {L-(-R)}.
It uses a lot more line receivers but since you're interest is virtual simulation and would never be built there isn't any overhead.

Yes this is what I have been doing since I have a balanced/differential front end to feed it with, both polarities are already available. I am really sold on your ina style front end, using cross coupled line recievers, so I use that topology. Also, I believe, please correct me if I'm wrong, doing the conversions differentially can produce up to another 6dB of separation over the single ended conversions.

You can also do the Mid and Side Extraction using cross-coupled stages to obtain anti-polarity outputs to feed the insert.

Not sure that cross-coupling would give you an extra 6 dB separation but it would increase headroom.
