 Fader Start doesn’t work.
• Set a cue.
• To activate Fader Start, mark the [Fader Start] check box in
[Preferences] > [Controller] > [Mixer] tab in rekordbox.
 When the unit is disconnected, recording isn’t available in
rekordbox.
• If you don’t have one of the relevant subscription plans, you can’t
record without connecting to the unit. Connect the unit or another
Hardware Unlock device, or take out one of the relevant subscription
plans to enable recording.
Lighting fixtures
 A Lighting fixture doesn't work with the unit.
• The [DMX] output terminal of the unit is for use with rekordbox
Lighting mode only.
Check the channel setting of the lighting fixture and that the cable is
connected properly.
Next, check the channel setting and relevant lighting fixture is
mapped to the correct channel on the
[FIXTURE LIBRARY] screen
of the [LIGHTING] mode screen in rekordbox.
If the mapped item is automatically displayed as [No Assign] in the
pull-down menu of the window on the right, the lighting fixture may
not be supported by rekordbox. (In this case, change
[No Assign] to
the other setting, which may solve the problem.)
