Connection setup help

Hi all, new here.

So I have had a Digitone for a while… Hooray! I love it.

I am thinking about new gear to add over time, to which I have a few things in mind.
Would it be possible to get some input on how to connect everything I have in mind together. Help me understand what cables I would need, and help me understand the hardware chain.

Here is the gear list that I want to achieve.
Mixer (From Send Return), Digitone, Digitakt, Synthstrom Deluge.

Alternatively
Mixer (From Send Return), Octatrack, Digitone, Digitakt, Synthstrom Deluge.

I would like the Deluge to be the heart of this,
Thanks for any help.
