Settings

This section contains a list of all properties that allow configuration of the alphaTab behavior.

There are multiple ways how settings in alphaTab can be specified. For .net, the normal classes are used and changes are signaled via an UpdateSettings call. For JavaScript, the interaction with the settings is a bit more sensitive due to the lack of type safety and the support of JSON based settings.

Not all settings contain reasonable examples as they often just activate something within alphaTab or change the display of some notation. If you have questions on certain settings, feel free to open a Discussion on GitHub.

The first and most important rule is: when interacting with the settings object directly, the correct structure and data types must be followed to not break alphaTab or make the changes useless. In order to simplify things when configuring alphaTab via JavaScript there are 2 additional features:

  1. AlphaTab can be configured via a simple plain JSON object. This JSON format supports some aliases and also some value conversions like for enums, fonts and colors. The JSON schema can only be used at selected places. Attempting to set JSON values on the derived alphaTab.Settings object can lead to unexpected side effects. The JSON schema can be used when initializing alphaTab or when calling settings.fillFromJson( ... ).

  2. AlphaTab can be configured via HTML data attributes. All settings can also be added as data attributes on the element for which alphaTab is initialized. This is especially useful when multiple different instances of alphaTab are running on the same site but the main code to set up alphaTab is shared. Individual settings can be specified on HTML elements.

The following table contains all the properties as they can be set on the general settings object.
