Hi,

Not exactly, an [FMOD Engine | Core API Reference - ChannelGroup](https://fmod.com/docs/2.02/api/core-api-channelgroup.html) is like a [FMOD Engine | Studio API reference - Bus](https://fmod.com/docs/2.02/api/studio-api-bus.html), while a bus is not like a channelgroup. However, we can use our bus to access the channelgroup we want to play our sound on without having to worry about the index of the channelgroup. I have an example of accessing a specific Bus in Unity here: [Audio Stream to programmer instrument - #4 by Connor\_FMOD](https://qa.fmod.com/t/audio-stream-to-programmer-instrument/20519/4), hopefully this is what you are looking for.
