Hello,

I am using FMod with UE4 and I got simple question:

Is one event always occupies only one channel no matter how many sounds are playing at the same time. Or every sound in the event needs separate channel.

Thank you.

The number of channels used by an event can vary, but it’s usually at least one channel per event instance, and could be many more. As a result, the more events and the more instances of each event you have playing at the same time, the more channels exist.
