Thank you for this added information. The images were helpful in clarifying your points. I noted in one of the PGMusic training videos that Steinberg makes an ASIO driver that will operate with two applications. Perhaps this might be useful for what we have been discussing.

I think I have enough information, thanks to you, to proceed with my project. I will post how I am doing as I go along. I am sure there will be a question from time to time.
