It was said in this Pitchfork article that JPD mainly uses this synth on the first Damaged Bug record "Hubba Bubba" and probably on the later ones too.

You can see the Arturia Microbrute situated among John's synth set up a few times throughout the video, particularly at 10:13. He's not playing it during the mentioned time stamp but it's clearly visible under his right arm.
