General Notes

File format and location

The skin.ini file must be located in the config folder, along with the other ini files managed by the configuration software (e.g. mAirList.ini). You must create it manually using a text editor.

The file uses the typical syntax for .ini files:



The available section names and key names are given in the reference below.

:!: Please note that some settings currently do not work as described. This mainly concerns the “can be left empty” descriptions.
If you cannot achieve the desired effect here, the entry for each status has to be entered individually. The corresponding passages are – temporarily –
crossed out.
We apologize for the inconvenience and ask for your understanding.


All colors are specified in HTML color format, with six hex digits, e.g. #FF0000.


For all fonts, there are four available settings:

FontName Name of the font, e.g. Arial
FontSize Size in pixels
FontColor Font color in HTML format
FontStyle 1 = bold, 2 = italic, 4 = underline, 8 = strikeout; add numbers to combine styles, e.g. 5 = bold+underline

In the reference below, we will only give the base name of the font setting, e.g. TitleFont – the available settings are then TitleFontName, TitleFontSize, TitleFontColor and TitleFontStyle.

The following settings apply to all “graphical” buttons (not standard Windows buttons), e.g. the start/stop/… buttons of the players, and toolbars built from these buttons (e.g the playlist control bar).

The button settings are prefixed by a particular button identifier as specified below, e.g. PlayButtonActiveFontName.

UseGradient Use gradient fill? Default: off
<State>Color The background color
<State>GradientColor The gradient background color (if UseGradient is enabled)
<State>BorderColor The border color
<State>Font The font to use (for buttons that have text)
<State>FontColor The font color to use (for buttons that have text)

The available states are:

Active Button is active
ActiveHover Button is active, and mouse pointer is inside button
Inactive Button is inactive
InactiveHover Button is inactive, and mouse pointer is inside button
Disabled Button is disabled

You can also leave out the <State> part in the rule name to adjust the settings for all states at the same time. Use only Button as button identifier prefix, e.g. ButtonFontName.

Button toolbars

The following settings apply to all toolbars made of graphical buttons – currently only used for the Cartwall toolbar. The individual buttons can be adjusted by prepending their <ID> to the particular settings.

Height Height of the toolbar
FullWidth Use all available horizontal space?
BackgroundColor Background color
<ID>ButtonVisible Set to off in order to hide the button
<ID>ButtonMarginLeft Left margin in pixels
<ID>ButtonMarginRight Right margin in pixels
<ID>ButtonMarginTop Top margin in pixels
<ID>ButtonMarginBottom Bottom margin in pixels
<ID>ButtonCaption Button caption (for buttons that display a text)

Tree/list colors

All tree- and list-like components (e.g. the playlist, browsers, …) have a couple of common settings that can be used in the appropriate settings:


Main Window

General settings

For the general settings, use the section [MainWindow].

Color General background color
Background Full filename of a background image to use; works only in custom layout mode


The section [Toolbar] controls the appearance of the toolbar in the main playout window.

Visible on or off (default: on)
List In “List” mode, small icons are used, with the text next to them; default: off
Captions Show button captions? default: on
AutoSize Automatically adjust size? default: off

You can also hide the individual buttons in the toolbar (and the separators between them) by setting any of the following values to off:

ShowNew New button
ShowOpen Open button
ShowSave Save button
ShowSeparator0 Separator between Save and Insert
ShowInsert Insert button
ShowProperties Properties button
ShowDelete Delete button
ShowSeparator1 Separator between Delete and Actions
ShowActions Actions button (if Menu Actions are defined)
ShowEvents Events button
ShowCartwall Cartwall button
ShowMixEditor Mix Editor button
ShowVoiceTracking Voice Tracking button
ShowBrowser Browser button
ShowSeparator2 Separator between Browser and mAirList
ShowAbout mAirList button


Use section [Playlist] for settings that will effect all playlists, [Playlist0] only for the first playlist, [Playlist1] for the second, and so on.

Row appearance

The following settings can be used to change the appearance of the rows in the playlist:

DefaultRowColor The default row background color (if no other entry matches)
<Selector>RowColor The background color
<Selector>RibbonColor The ribbon color (since version 6.0)
<Selector>RowPadding The row padding (extra space between text and cell boundary)
<Selector>Font The font to be used

About selectors

Selectors allow you to specify settings that only affect particular rows, based on their type, state, etc. If you are familiar with HTML/CSS, this is pretty much like HTML classes and CSS class selectors.

For example, to change only the font of the “Title” column, use:


Another example: Set the background to red for all items that are currently playing:


You can also combine the various selector options – change the font style of the “Title” column for items that are currently playing:


Generally, the selector for RowColor and RowPadding rules has the following form:

[Alternate]<Player State><Item Type><Item Class><Level>

For Font rules, there is an extra Font Category component:

[Alternate]<Player State><Item Type><Item Class><Font Category><Level>

The available options for the various components are described below. You can leave out any component, e.g. Player State, in which case the line will match all player states.

Remember that the skin.ini file is parsed from top to bottom. If there are multiple lines that match a particular row, the last line will have effect. So you should put more general rules to the top, and more specific rules to the bottom of the list.


Rules starting with Alternate will only affect every other row – they allow you to create a striped table like this:


(Note that the – more general – RowColor rule comes first, it would override the AlternateRowColor rule otherwise.)

Player State

The following values can be used for Player State in order to select a row based on the state of the player in which the item is loaded:

Loading Player is being loaded
Loaded Player is loaded and ready
Next Player is loaded and ready, and is next in sequence
Playing Player is playing
Fading Player is fading
EOF Player is at EOF
Error Player has an error, or prebuffering failed
Paused Player is paused
PFL Player is in PFL mode
Empty Item is not loaded into any player
Played Item has been played
Skipped Item was skipped
Overflow Item is “overflow” (will be skipped due to a following fixed time item)

There are two special “Player State” values that are used for rows that do not represent playlist items:

Underrun An “Underrun” indicator node
Region A region node (when you expand a Region Container playlist item)

Item Type

This component selects a row based on the Item Type as set in the item properties. Currently, the following values are available:


Item Class

In addition to the Item Type (which the user can edit in the Properties dialog), you can also select rows based on the Class of the playlist item:


Font Category

The following fonts can be adjusted through the skin:

PlayerName The font used for the name of the player that the item is loaded into
Backtiming The font used for the backtiming info displayed in the “Time” column
Title The font for the title of the item
Artist The font for the artist of the item
Duration The font for the Duration column
Ramp The font for the Ramp column
Ending The font for the Ending column
Attribute The font for all attribute columns
Comment The font for expanded comments
Warning Font used to display warnings, i.e. the Underrun warning etc.


When the Expandable Containers GUI option is turned on, and you click the + button to expand a container, there will be a hierachy of playlist items, and the playlist will act like a tree. (And the container could have another container inside!)

The optional Level component in the selector allows you to define rules only for a particular level in that tree, e.g. to use a smaller font for the items inside the container. Level 0 is the top level, level 1 is for the items inside a container on top level, level 2 for items inside a container inside a container and so on.

DefaultRowColor vs. RowColor

DefaultRowColor and RowColor appear to do the same thing, as they define the color for all nodes that have no specific skin.ini setting (note that RowColor has an empty selector, so it matches all rows). But there are two differences:

  1. DefaultRowColor only affects playlist item nodes, no “region” or “underrun” nodes.
  2. When the GUI option /Item-specific colors have priority over skin.ini/ is turned off (so that skin has always priority over item-specific colors/, and you have a plain RowColor rule, that rule would always override the item-specific colors. Use DefaultRowColor instead in this situation (it has always lower priority than the item-specific color).


The following settings control the position and appearence of the ramp/EOF overlay display:

OverlayFont Font to be used for the overlay
OverlayFontColor Color of the overlay font
OverlayBackgroundColor Fixed background color; default: transparent
OverlayOutlineWidth Width of the font outline
OverlayOutlineColor Color of the font outline
OverlayPosition Inside the playlist display, as cardinal direction: N, NE, E, SE, S, SW, W, NW. Default: C (center)
OverlayPaddingX Horizontal padding
OverlayPaddingY Vertical padding

Progress bar

Use the progress bar color settings described in the General section above.

Control bar/toolbar

To adjust the control bar (toolbar) of the playlist, add section [PlaylistToolbar] and use the following settings:

BackgroundColor Background color
<Button>Button Appearance of the individual buttons, see General section above

The available buttons are:

AssistAuto Combined ASSIST/AUTO button
