I’d like to have one sustain pedal connected to two keyboards . I’m therefore wondering if it’s possible to connect the pedal to the sus input on the Keylab MKII and then run a wire from a CV out to the sus input on the secondary keyboard. I know there’s a risk of damaging the equipment with wrong CV connectivity, therefore I’m asking before I attempt any setup. Alternatively if there’s a better way to do this I’d like to hear about it 
Hey @Handerre nice to see you here!
From our side we never tried this before, but as we see it will be less dangerous if you try it using a MIDI signal to connect your second pedal.
Good luck with your experiment! and please let us know if you arrive to make it work from your side!

Oh wow, just got a prompt that this is a year old topic, from Aug '23! I’m going to put this here anyway… If both keyboards use the same type of footswitch (the footswitch works correctly with both keyboards) then you can use a Y cable to connect the one switch to both keyboards. You have to get or make a mono female to 2 mono male cable, not a more typical stereo female to two mono males. (A true “Y” cable.) Thus no need to mess with questionably compatible CV connections.
