So Im working on putting some FMOD Sounds in a channel that I can just change a value in the channel to adjust all their volumes based on the channels volume. Since im doing this in Unity and C# im alittle lost about what I should be using to create and use the Channels from FMOD. Thanks in advance

The default Unity integration doesn’t currently expose Sounds and Channels, so I’m a bit confused how you’re seeing those. However to answer your question System.playSound creates an Channel to play a Sound. Note a Channel represent a single playing instance of a Sound. If you want to control multiple channels with a single object you can add them to a ChannelGroup. (System.createChannelGroup, Channel.setChannelGroup & ChannelGroup.setVolume)
