This part is actually pretty easy for you to do. It involves using our
ControlObject system. ControlObjects are a way to share values and
notifications about changing values across Mixxx. We use this for everything
from connecting MIDI and GUI to the mixing engine, to displaying indications
in the GUI (such as the current end-of-track mode or whether a deck is
playing).

For the appropriate deck that is being controlled, simply create a
ControlObject with the key '[PlayerX]' and name 'vinyl_control_enabled' or
'vinyl_control_focus'. When the deck is currently being controlled via a
timecode/turntable then set this control to 1. When it is not being
controlled, set it to 0.
Now all a skin designer has to do is listen for changes to that control to
determine which PNG to display to the user.

Is this going to be per-deck or for all vinyl-control at once?
If it's per-deck, do the same as before but make the control:
'[PlayerX]', 'vinyl_control_mode'
If it's not per-deck, but a global vinyl control option, then instead of
'[PlayerX]' for the group, use '[VinylControl]' (or whatever group any
existing vinyl control code uses)
Pick a standard that 0 is absolute and 1 is relative (or the other way
around, however you like it). Now in order for a skin to be able to show
that they would simply use a <Display> group to show an image based on the
value of a control. This is how our play/pause button works and the
end-of-track buttons in the outline skin.

In this case, do the same as above. Create a '[PlayerX]'
'vinyl_control_skipped' control. Set it to 1 when the vinyl is skipping and
0 when it is not. A skin writer can make a big red alert show up in the GUI
when the control is 1.

Hope this helps,
