Sending Logic Audio to Rytm/A4 and back

Hi guys,

I’m using a Rytm mk2 and Analog Four mk2 together with Logic X.
Everything is setup and working pretty good with overbridge to record multiple channels.

The only thing I can’t seem to work is sending audio from logic back into the machines to use their analog effects/filters/overdrive.

The plugins in Logic are not showing the button the route this (I think it’s called the sidechain button?) The stand-alone plugins do show this button, but then I can’t use it with Logic.

Does anyone know how to use this or a reason why this isn’t working?
