This is a real noob question i'm sure, but how do i go about
redefining
negative value data i'm getting (within the range -0,5 to 0.5) so
that it
works on a scale of 1.0>2.0 ? I can't do this through
multiplication in the
math patch, and i encounter this type of thing all the time (due
to alot of
data sources using negative values).

Why not just add 1.5?
thanks for that .. thats great, but what about when i want to convert
-0.5 > 0.5 to 1>1000 for example? is there a way of just taking the
whole range and remapping it somehow?
You just need basic remapping arithmetic, like this:
outValue = (inMax == inMin) ? outMin : (outMin + (inValue - inMin) *
(outMax - outMin) / (inMax - inMin))
