the new version has an offset, this will almost definitely do what you want - checked the manual - it seems to only be a +ve offset
to convert -3/+5v to 0/8v you would apply a +3v offset - possibly you'll want some way to monitor this, although for modulation maybe not necessary
to then to then get to 0/10v you want to amplify by 1.25 - again possibly you'll want a way to monitor
then a simple inverter will get you to -10/0v - I use a malekko invert mix to do this, which is a small and
I don't think there's any 1 module that will get you all the way there for 8 channels - but then again, you probably don't need 8 channels of -10/0v
I don't think I would need that many channels of -10/0v modulation (& I've got 1600+hp)
another option might be 3 happy nerding 3*mia - I think each channel can invert and amplify

Utility modules are the dull polish that makes the shiny modules actually shine!!!
