  • To use this feature, toggle Enable SuperSource Macros when editing your Switcher Connection.

  • Edit your presets and select a macros to be executed when running or exiting from a preset.

  • Exported presets will have the Run Macro and Run on Exit Macro flags disabled upon import to prevent accidental macro triggering on other switchers.
