The MiniBrute 2S has a CV clock in and clock out. This means you can sync additional sequencers to the MiniBrute. You noted that you were using the internal sequencer. What you can ALSO do, is trigger more modulation via an external sequencer or other sound modules, reset LFOs, etc. I believe the 2S sequencer only handles gate and pitch (one channel of CV).

Sequencers come in all sorts of styles, shapes, and sizes. So what works best for you I wouldn't know. But it's something to think about if you're "expanding" your MiniBrute.
