I'm trying to create a slider that has the value 1 at center and moves positive and negative from that point (e.g. if I move the slider from center toward the left I get output of -1.5, -2, -2.5, etc. and if move it from center to the right I get output of 1.5, 2, 2.5 etc. For the life of me I can't figure out how to configure the slider values and/or scaling factor so I don't end up with zero in the middle. Probably not thinking of something obvious...
