With the most recent update I love that you added support for the N4, but there appears to be a problem with Pre-cueing. When I press the cue button on the controller or on my screen, the program does not set the deck into pre-cueing. I’m wondering if there is an issue with the software the is currently preventing it from setting up pre-cueing. Other than that I love the integrated support with my controller.
Please double check your “Devices” settings at the djay Pro Preferences. Make sure your N4 is chosen for both, Main Output (Channel 1-2) and Pre-Cueing (Channel 3-4). Click on “Apply” afterwards.
