Emulating unipolar macro knobs with X-Y in e.g. Zebra

[Chalisque]

Is there a right way to go about this in Zebra?

The X-Y is bipolar, with 0 in the middle. Most macro knobs in synths are unipolar, with 0 at the start. Sometimes I want that. If I map a knob on a midi controller to the X-Y, I want fully counterclockwise (CC val=0) to map to 0 on the X-axis, and fully clockwise (CC val 127) to map to full on the X-axis. I want the position of the e.g. VCF cutoff to be where it will be when the knob is at CC val 0.

For your example: Set Cutoff to 75 (centre) and do this:

In some Uhe synths (e.g. Hive) you can use the Mod Matrix "rectify" or "unipolarize" features.
