Thanks notnat & blipp.
Some of the midrange is a wandering effect(s) on her voice. I have several copies going, reverse reverb, parallel comp, etc. that gets a little sharp or harsh. But she kept saying make it sound more mechanical or robotic. Usually I'm the one who has ... different ... tastes ;-)
And I probably need a different recording room, too. But I'll go back to the track eq filters.
