How do I vote for this !! I hate using my controller because of the same reason I start mixing with my eyes so I try and use vynil or cd's on cdjs to remove the visual cue .... please add something like this, its as easy as adding a function that makes the beat grids transparent or disappear.
Options for a practice mode
Digital screen - showing dot matrix information only
Remove beat grid
Remove the tempo indicator
Something like that .... not very difficult tbh, not for skilled engineers like pioneers should have.
