I just recently purchased a Doepfer Dark Time sequencer in hopes of using it to control my Little Phatty. I’m new to signal flow and synthesizers, and was wondering if somebody knows the proper way to hook up the sequencer to the synth (which outputs I’d plug into which inputs etc.) Sorry for the noobie question, but any help would be greatly appreciated!
I’m using a Dark Time with my Slim Phatty & Minitaur, so maybe I can help a bit… 
The easiest will be MIDI OUT of the Dark Time to MIDI IN of the Little Phatty.
That one connection is enough to start sequencing your Phatty.
Once you start adding CV to the mix, it can get a bit more complicated - and also very cool!
So, in lieu of the MIDI connection:
At the very least, Dark Time GATE OUT 1 will need to go the Phatty GATE IN.
Dark Time CV OUT 1 will need to go to Phatty PITCH IN.
That should get you started… 
The Dark Time CV OUT connections can actually go to ANY of the Phatty CV IN connections, depending on what Phatty CV parameter you want to automate with the sequencer.
You’ll want to spend some time with the Dark Time manual, and be sure to head out to the Doepfer web site and download the manual updates, check the firmware programming notes, etc. Also, check YouTube - there are a few videos posted of the Dark Time in action with some Moog gear!!
You’ll find that the Dark Time is actually a VERY powerful sequencer in a small package, and there’s a lot you can do with it that isn’t necessarily obvious from the buttons and LEDs on the panel. Explore, experiment, and have fun!!
