My minimal studio uses an A4 / Microbrute arrangement too. There might be more efficient CV settings, but mine are as follows:
A4 Function > Global > CV Config:
- CV Config A: Type = Gate; Polarity = V-Trig; Level = 5.0 V
- CV Config B: Type = Pitch V/oct
Using split cable, connect CV AB Out to Microbrute:
- A4 CV A out to Microbrute Gate In on back of machine
- A4 CV B out to Microbrute Pitch In on Mod Matrix
Microbrute Line Out to A4 Input (Right)
On A4, select FX track, then External In parameter button - increase track volume and set the pan (you should hear the Microbrute coming through the A4 now if you play some notes on the Microbrute); you can also set your effect levels here, too.
Select CV track and you should have the ability to play the Microbrute using the mini A4 keyboard and add trigs on the sequencer.
