As far as stand-alone, you have your Arturia Keystep that can handle basic sequencing. Depending on your needs, you can always add Eurorack sequencers. There are so many types and styles, that's an entirely different conversation.
As far as integrating your Eurorack into your set-up, I would have two things purchased: 1. A MIDI to CV converter that can transform MIDI messages into gates and CV. There are quite a few of these as well. There are full programmable USB MIDI to CV converters like the Expert Sleepers FH2. Then there are simpler 5-pin MIDI to CV that many companies make.
2. Synth-level to line level converter. Eurorack levels are a lot hotter than the output of your DeepMind or DrumBrute. A dedicated converter is great for a no-muss/no-fuss dealing with this. A stereo unit is usually enough unless you're trying to isolate sounds in a large set-up.
There are other methods, like generating CV and gates directly from your DAW as well buying an audio interface that works at Eurorack levels (like the Expert Sleeper ES9)... but depending on your set-up and if you already have a regular audio interface, this can get a little tricky, especially with a PC.
