After further use of the Witches Brew.  I decided that the passive attenuator section is pretty redundant with the range knob. No point in having it making things more complicated and take more time too build. I am also adding the Option to have a Inverted X/Y output. Too add more flexibility too the module.  Things have been Slow, But it shouldn't take long too redo the PCB. This is a great article about Offset Scalers. I found this when Modular in a week introduced me too that page and was a interesting feature too add.
