1. Will it allow me to output chords to a "USB to Midi" hardware device while maintaining my BIAB midi out for the midi tracks?
.
2. If yes, can I do this on the fly, without having to load the midi chords of every song into an empty track in the mixer?

I assume the answer to at least one of the above questions is no. And as I said, it's only worth it to me if it can be done simply. Thanks again, Pipeline for your tenacity.
