If this is your first set-up, I would think about getting a 1010 Music BlackBox or the new Akai MPC One.
The BlackBox has clock in and out, while the MPC One has four gates and four CV outs (I believe they use stereo 3.5mm breakouts).
You're spending a ton of money for the same or lesser functionality in order to place it into the Eurorack environment when a standalone device would serve you just as well and still interface into a Eurorack environment down the road.
