Hi Florian. I did try to adjust the VCO disconnected from the A-190-2, by trying to make octave jumps from Range 0 to +1, +2 and -1. I've adjusted potentiometer P6 that the VCO Range 0 would sound the same note as a C1 from my keyboard. I've tried to make the octave jumps turning the P7 and P5 potentiometers. It's like I have a shorter scale, since I have a C note at Range 0 and a B note at Range +1.

Altough I'm noting right now that a chart from the "VCO-Offset and Range adjustement procedures" at service manual tells that C2 would give me a lower octave and so on. Wouldn't it give a higher octave
