I'd go with ardour.  There are some LADSPA plugin meters that
will do what you want.  I too find ardour to have surprisingly
light load on my 2GHz Celeron with 1GB of RAM.  What soundcard(s)
are you using for your 18 channels?  I'm using an 8ch M-audio
Delta 1010.  I expect you might need/have RME gear with all of
those channels.  Join the ardour list if you want to learn more
about that.
