I am sure you are not working in post pro business, are you?
In film mixing (with location sound) I use 7 bands all the time:
LowCut, Hicut, 2 bands for attenuation of room modes, 2 bands for voice brilliance/presence, and one more for noisy problems.
Of course, well done music recordings in great sounding studios propably do not need an eq…
But the title of this thread asks for a proper Post Eq. And that should be delivered by steinbergs post-daw, imo.
