I’m having issues with the pre cueing in the above set up. Sometimes the headphones will output sound of the non master song then it will just stop working with either massively reduced volume and lack of parts of the music or no sound at all. The only way to get it to work again is to unplugged the iPad and plug it in again.
I checked all the settings in Djay and they appear ok and clearly if they were wrong, it wouldn’t work at all rather than intermittently. I’m using Tidal as the music source.
