There are two things you need to do.
First, you decide whether you want to create External Instrument under your vst connections, and then open hardware synth like vst plugin. I do this more often than creating midi and audio track, which is your second option.
Having set MB as external instrument, you will enter midi data into track. How to do it?
First, make sure that in midi connections your device is connected to appropriate chanel, sending in/out midi.
Second, click sync tab on your transport panel - CMD plus click - it will open sync menu. If you are using usb, you will see “Minibrute 2s midi out” in midi clock panel - tick it! On MB, set Sync from internal to usb (or Midi, if your connection is not usb) - mb must not be in play mode when switching sync. This will place MB in slave mode to Cubase, listening to its Midi Clock, which also overrides tempo on mb - it will be the tempo set in Cb project. As soon as you press play or record in Cubase, MB will send sequence to QB in form of midi data. Bear in mind that beside notes you can send all kind of midi data AND this includes knobs on MB, vis CC commands. For this you need setting Midi CC from Arturia. However even without setting, your mb will send midi data to your instrument (or MIDI) track.
When you finish your fancy automation on knobs, render in place, so you convert it into audio - CB will record your clip in real time.
Hope this helps.
