Information on synchronous and asynchronous instruments can be found here ([https://www.fmod.com/resources/documentation-studio?page=working-with-instruments.html#synchronous-and-asynchronous-instruments](https://www.fmod.com/resources/documentation-studio?page=working-with-instruments.html#synchronous-and-asynchronous-instruments)), and information on cut behavior can be found here ([https://www.fmod.com/resources/documentation-studio?page=working-with-instruments.html#cut](https://www.fmod.com/resources/documentation-studio?page=working-with-instruments.html#cut)), in our new online manual for FMOD Studio.

The “Async” toggle button only appears on instruments that can be toggled between synchronous and asynchronous. Event instruments, scatterer instruments, and snapshot instruments are always asynchronous, as are all instruments on parameters. Such instruments do not feature async toggle buttons.
