Hi there, Thanks for your patience, and for making what you’re saying clearer.
• The MC7000 has the load buttons included as part of the scroll knob
The behaviour of Serato DJ is currently set to change focus when in the files panel, and using a controller in the second group. I’ve reported this as a Spec bug with our development teams, they will either decide that this is correct behaviour, or that there is an issue to be included in the Bug backlog at the appropriate priority. In the meantime, [shift]+[left arrow/right arrow] should load the track to deck. I hope this helps. Kind Regards,
Customer Support Team
