Public variable UProperty Category, EditAnywhere BlueprintReadOnly EMetaSoundOutputAudioFormat OutputFormat The output audio format of the metasound source.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite Config FName QualitySetting The Quality this Metasound will use. These are defined in the MetaSounds project settings.
Public variable UProperty FGuid QualitySettingGuid This a editor only look up for the Quality Setting above. Preventing orphaning of the original name.
