Doesn't really make sense to replicate those vintage Vu meters on a digital screen.
The needles where so small to give them as little mass as possible - because of the physical limitations, to make them more responsive. They are not ideal to show on a digital screen as used in the Ultra.
It's probably more practical to show a multi band meter/spectrum analyser...
Anyways, this is going to be my last post of the year. Happy new year folks!
