Re: PAiA 9720 VCO Pulse Width - Goes quiet when fully CCW.

I'm about to continue testing my midi2cv8 and VCO, but I don't understand how I should connect it? And how do I measure that the CV output from the midi2cv8 actually is 4V? I don't understand.

PAiA 9720 VCO Pulse Width - Goes quiet when fully CCW.

Please help me! I have a problem with the initial testing of my newly built 9270 as a part of my 9700s kit.
