    Design Time Parameters<\/strong><\/p>\n

    The VncControl audio object has one additional configuration variable: Block Control. This can be configured during design time so as to enable or disable Block Control feature. <\/span>The default value for \u201cBlock Control\u201d additional configuration is disabled (0).<\/span><\/p>\n

    \"\"<\/span><\/p>\n

    When Block Control is enabled(1), 6 speed dependent control inputs are grouped.<\/span><\/p>\n

    \"\"<\/span><\/p>\n

    When disabled, control inputs are not grouped.<\/span><\/p>\n
