hi folks, im hoping someone can help me finish calibrating these modules.
i have 1 fully built and wired VCO. i was able to do the 1st step of setup, setting V at pin 7 of said IC to 0 volts. when i try to SCALE to 1V/oct, the "span" trimmer just affects the overall pitch, but the scaling stays the same.
i thought i might have a wiring problem, so i took the 2nd of 3 completed PCB's, and wired up just the tuning pots, output jack, and V/oct pot. i get the same behavior on this, so im pretty sure i've got a build misunderstanding or something.
all PCB's are rev 0.5. any ideas what might be wrong? thanks.
