I’m glad it works on your controllers, I’ve got a DDJ SX2, the Browse button is mapped to Switch Library Table and the program totally ignores the Queue, even when tracks have been added and previously selected.
This is the same on an iPad Pro 12.9 and an M1 MBP.
I’ve remapped the controller to within an inch of its life so I don’t have to interact with the keyboard/mouse/screen but I still have to if I want to get a song from the queue.
Another thing I have noticed is if you put a track in the queue but don’t select it, no amount of tab presses will take you to the queue either, the tab cycle ignores the queue until you’ve clicked on a track in the queue and highlighted it, from then on the tab cycle does pick up on the queue. So another anomaly.
If your DJ2GO works with the switch library table MIDI command, this would suggest it’s something more specific to the SX2 mapping in the background.
As for Automix I never use it (apart from a long soak in the bath from my iPhone 
) so don’t really notice the issues with this function.
But being able to get to the queue from the controller should be basic functionality, that currently seems broken, with an SX2 at least.
Just for reference, the original thread is here.
