I looked up the API doc on Virtual Voice System,[https://www.fmod.com/resources/documentation-api?version=1.10&page=content/generated/overview/virtualvoices.html](https://www.fmod.com/resources/documentation-api?version=1.10&page=content/generated/overview/virtualvoices.html)  
on Event Polyphony with Voice Stealing On/Off sector,it says “In this mode…”,but my programmer can’t find where to check if it’s ‘voice stealing on’ mode,or ‘voice stealing off’ mode,so my question is,where to check which mode is it?Or is it by defaut ‘voice stealing on’ mode?  
Thanks

The stealing behavior is set in FMOD Studio on the Event or Bus:  
[https://www.fmod.com/resources/documentation-studio?version=1.10&page=event-macro-controls-reference.html#stealing](https://www.fmod.com/resources/documentation-studio?version=1.10&page=event-macro-controls-reference.html#stealing)

Turning on Vol0 virtual is done in the [FMOD\_INITFLAGS](https://www.fmod.com/resources/documentation-api?version=1.10&page=content/generated/FMOD_Studio_System_Initialize.html) of the [Studio::System::initialize](https://www.fmod.com/resources/documentation-api?version=1.10&page=content/generated/FMOD_Studio_System_Initialize.html).
