what’s the contact between Bank and EventInstance?Can I get some data of bank from EventInstance?
An EventInstance does not refer to or know about Banks.
A bank contains FMOD Studio Event data as well as the actual sound data for all events in that bank.
Event Descriptions belong to banks and can be queried after the relevant bank has been loaded. Event Descriptions can be found either by looking up by GUID or by querying all descriptions as part of a bank.
An EventInstance is an individual instance of an Event, eg. created from an EventDescription.
