no problem

well there really is nothing special to consider, syncing elektron gear is no different than any other piece of gear in the universe

here are the possible ways you can connect

up to 6 audio outputs feeding into your interface card, into cubase tracks (4 mono for tracks, and a main output stereo pair). The only configuring to do here is setting up pathways from your audio interface in cubase

you can send audio OUT of cubase, INTO the analog keys as an effects processor, and then back OUT into cubase. This is where the latency would be the biggest issue

MIDI - you can use the USB cable to do midi in/out, which I recommend. Its class-compliant so cubase will see the analog keys automatically. Set up the input/output channels and you can playback midi through the AK or use the AK as a midi controller

you can also use the actual midi din connectors with other gear, I dont know much about that
