CMC-AI Knob Controller - Newbie needs help!

I just got the CMC-AI Knob controller and I’m trying to figure out how to properly use it. Specifically, I’m trying to get it to control parameters within Native Instruments Massive VST. I have one of the macro controls set up to modulate an LFO and I want to use the CMC-AI to control that parameter. When I use the midi-learn function to detect the knob controller and use it to tweak the LFO, it’s not quite working correctly. The macro control just jumps drastically between two values when I turn the knob, I can’t get it to adjust to any specific value between them.

Basically, the parameter just jumps between “0%” and “50%”, and I can’t get it do do anything else. Whereas when I just use my mouse and click on Massive I can adjust that macro control to whatever value I want.

Does anyone know how to fix this? I’ve ready through the manual but it’s not very detailed at all and I can’t seem to figure out how to work this thing. Thanks!
