Subharmonicon - weird VCO 1 & 2 link behaviour when using CVs

Hi,
I’ve bought a midi controller that sends CVs to control the pitch of my VCOs.
When I plug a cable in the “VCO 1” input in order to change the pitch, it also changes the pitch of VCO 2 - not the opposite though, only 1 changes 2.
It’s a bit disappointing, since I thought I could be using 2 different vcos with my midi controller to trigger independant melodies and rhythms.
Has anyone encountered this issue ? If that’s not normal, could it come from the update ?

Thanks

block diagram in the manual shows the VCO2 CV IN is normalized to VCO1 CV IN.

tbh, i don’t see what your problem is.

Hi !

Same remark here: you have the option of using two separate CVs or to use one for both oscillators.

The point you might be missing is that you can do this with CVs only, not MIDI.
