Moog Source via MCV4 CV Scaling woes

Say all, I’ve got a CV question: I am having scaling issues as my Source scales up: to adjust that is it an internal pot or a midi command from the MCV4?
I cannot suss out that info.
Also, the Source always seems to be playing the control note: any tips to fix that? Kinda annoying.
Thanks.

I’m having the same problem actually, any help would be much appreciated.
