Hello kind polysix users!
I am having tuning issues with my poly6... ive replaced the optocoupler and resistor and replaced ic16 with a new tl072 chip, but the keyboard is still having the same scaling issues as before. As I go through the manual for tuning it, I keep on reading about VR2, 14 and 15 and on the schmatic for klm-366 I see these pots, but i dont have them on my board... what is going on? I have vr1, vr3, vr4, and vr5 on klm366 and I have another VR1 on daughterboard KLM-396A. Here are some pictures of my board so you can get a better idea:

any insights? Thanks yall!
