it is not difficult with modular to tweak the CC: i used the compressor, associated to constant value bipolar and mixer, to control the range of a CC, and then assign it to a slider, in order to have a more precise control in a particular range.
it would be interesting to have a standalone device which permits to "reinterpret" midi CC values, performing on them math operations (adding an offset, compress/expand the values in a particular range, divide, multiply... who know what could be useful...)
