Uhhh, wha???  Do you mean turning the knob left sends out, say,
CC (control change) data on channel 1, and turning it right sends it
out on channel 2?

I can't fathom having a knob that controls parameter A when I turn it
to the left, and parameter B when I turn it to the right.  If I turn
a little too far and reduce my parameter beyond what I want, I have to
keep turning that way until I get to the value I want, instead of turning
it slightly the other way?

That's so unintuitive it'd make my brain melt.  Dunno about anyone else.

Keep in mind that there's no MIDI granularity of greater than 128.
You can't have a parameter that's < 0 or > 127.  That's a fundamental
part of the MIDI spec.

maybe I've completely misunderstood.  If I have, I'd be happy to be
challenged to think about the user interface in a whole new way.
