Analog four CV to Korg Arp

So…

I’ve currently got my A4 hooked up to my arp module. I have 2 1/4 inch to 1/8 inch stereo jacks connecting them. One connects CV-A tip set to gate on the A4 to gate in on the arp. The other connects CV-C tip set to CV to CV in on the Arp. Everything is turned on and the Arp is set as per manual to be making an oscillator trigger…
What am I missing here? Sorry if this is a really obvious fix, new to the world of CV.

Thanks, T

Think you need the cable going into the Arp to be mono. So you need a cable that splits stereo to two monos, rather than a TRS cable. Or just two mono cables.
