Sorry for the delay. I changed computers to an older mac and am having some connection issues now, however previously we routed the cat5 through a Thunderbolt/USB3 adapter to get into the mac. Then in the mac we use the Waves Soundgrid Studio as the virtual sound card and then Live Professor sees the card as an input and output. If we want also record multitrack simultaneously we use Reaper for both and the latency on the pitch correction is still OK. I haven’t tested if both Live Professor and reaper can work simultaneously without conflict.
We don’t patch as an insert, but come out of the direct out and return to a separate channel. Then the vocalist (and other team members) can choose the corrected or the non corrected for their in ear/monitor feeds. Corrected goes t the stream and the house. I am not certain if a vocalist hearing the corrected feed actually improves their pitch or if it makes it worse.
There is another software I would like to test but it is more expensive. Antares makes a plug in that will take an external reference (apparently a single instrument, or a mix) to determine the current key. A single instrument reference works well in TC Helicon hardware so this may be interesting.
Hope this helps a bit – good luck.
