TurboPlayer has a settings dialog for CrossfadeMixer/OnAIR TrackMixer. Unfortunately there are some parameters which cannot be changed with the dialog. This key allows to set these parameters. Every value you define in this key will be relayed to CFM/OTM. The value type can be: String and Integer. It is even allowed to define subkeys to build up hierarchical XML parameters. It is not possible to overwrite parameters which are already available in the dialog. For a list of possible parameters you have to check the technical documentation of CFM/OTM. (Since version 4.8.1708.0)
