Electribe 2 How to use as an EFX Processor

I often have smaller set ups at home due to space, so I'm always messing with different configurations and different bits of gear. Here I'm using the audio input of the tribe to use it's efx for my FR777. Here I'm simply connecting the Future retro 777 to my Electribe. Electribe set to INT sync and 777 to EXT. Audio out from 777 to the Tribe Audio in, that's it :)
