Sorry I’ve been busy with travel, a gig, and other end-of-year activities while preparing for an intensive Portuguese course, so I have been slower than usual at getting to these. I should have time over the next week to catch up though! |

| Menu rows represent the menus that appear on a CDJ or XDJ for browsing tracks in different ways. | ||
| The first field is a two-byte _category_id_ (labeled _cat~id~_) at bytes{nbsp}``00``-`01` which links the row to a <<column-rows,Column row>> and thus provides a label to the menu. This is followed by another two-byte value called _content_pointer_ (labeled _c~p~_) at bytes{nbsp}``02``-`03` that determines the internal content list that is accessed via this menu (e.g. the list of Artists, Labels, Genres...). | ||

| Next, there is a one byte _unknown_ value (labeled _u_) at byte{nbsp}``04``, followed by a one byte _menu_visibility_ (labeled _m~v~_) flag at byte{nbsp}``05`` which seems to determine whether the menu is shown or hidden on the player: value '00' means visible, while '01' means hidden. The value '02' has also been observed, but its meaning could't yet be determined, at least by testing with a CDJ-350 player which is quite old. It could be that this value is used by newer players only. |

There was a problem hiding this comment.
While this is in draft, “could't” should of course be “couldn’t” :smiling

Putting this here to hopefully gather some criticism and let it sit for a bit.
Various things that come to my mind:
content_pointerand write down their values in that field. This would make sense bc it does seem this value does point to the actual list/menu type in the player's firmware.#dysentery & crate digger > Menu and Column pages
