DUMB
I know better. I had reported that Native Instruments B4 was good, but not quite what I was striving for. I put my Muse Receptor in my 3 space rack by itself, and started over. I saw I had connected only the right out, as I use a Bose, which is mono. I know that a mono out is already summed to mono, but tapping one half of a R/L is not necessarily summed. I took both jacks out and summed to mono . This made the difference. What a sound !

Thanks, Diki, and all others for their suggestions. I would rather eat crow and fess up to a faulty assumption than to say nothing.
