Two mono balanced inputs to bluebox

[Lobosque]

Hi, what is the correct way to connect two balanced mono outputs, like Roland TR-8S into bluebox? I Tried using two inputs on Bluebox, but only one gets sound

I think this is what I'm looking for: https://1010music.com/product/35mm-m...ck-size=3+Pack

Most gear has unbalanced outputs, including the TR-8S. I can confirm that cable will do the job. I have a TR-8S here.
