This is what I did:

Now when I apply 1 volt to the upper Quantizer CV In it reads 1.006 volt at the CV Out instead of 0.924 volt so that's all right.
But after adding another 2 volt at Transpose CV In reads 2.918 volt so that's not right. Without the 330K resistor it then reads 2.836 volt.
I didn't solder anything yet. Just used clamps and cables to test.
Best regards,
