DJAY PRO2 Freezing on Mac with controller

I’m using macOS Catalina and have connected my Pioneer DDJ-200. After about 5-10 mins of use djaypro2 will freeze. This doesn’t happen when my controller isn’t set up. Help!

Hi, Thank you for getting in touch. @Rebekah, do you see a pattern what might cause the freeze? Any controls you are using before it freezes?

@RoDi We are sorry to hear that, could you contact us right away via

After upgrading to Catalina, my Denon Prime 4 isn’t recognized and when I manually map the settings, when I Hit the Left Deck Play Button, Djay Pro 2 crashes every time.
