bab... afaik the most you can have is 4 meters in Neb but I could be wrong... I have seen on the forums for the acqua plugins there is some way to add more meters but I don't think they are for things like multi track or say for surround... and again I don't think that ability is part of Neb3 at this time.
yes, more meter needles and then the calibration of each one in the xml file that makes the skin can give a better appearing meter.
I will be working on yet another test with even more needles and also with a smaller meter size.
Now what I do may not be exactly what you want, so here's a thought:
you could get into learning to make skins for Neb3. I'd be OK sharing with you what I've learned and also the graphics needed.
It is not terribly hard... but it can be tedious.
Also lets think through the mono stereo thing a bit more.
It may be that what you really want would be several instances of a meter only skin..
So let's start with sending you the N2S file as it is atm.
I'll be right back with a link.
Ok here ya go:

So when you get that working, let's talk about how your mono tracks work in it.
