Thanks but
(apologize if I have too much simplified the question)
what succeeds if I must convert one portion of that range ?
example 
I would want to convert 
the range 0.20 - 0.60 
in the range 0 - 127

in other word:

0.20 must become 0
and
0.60 must become 127

(I am making a patch that transforms whichever thing inside a pidip_canvas 
in one slider 0-127)

I have already made the subpatch (with the maths object :)) that make this trasformation
but 
the patch becomes more and more large and I asked if were a pd object that let me to save cpu.

many thanks
