Zoom MS-70CDR cabling for PO and Volcas

I have just been given a Zoom MS-70CDR pedal and I’d like to put a volca or a pocket operator through it.

What cables would i need?
a) for a PO as sound input (and still forward click to another device)
or
b) for Volca as sound input

will this work for a volca to the Zoom pedal?


I just use one like this: https://www.amazon.ca/Hosa-Cable-CMP110-Inch-TRS/dp/B000068O3D/ref=sr_1_3?ie=UTF8&qid=1507492028&sr=8-3&keywords=1%2F4+to+1%2F8cable
