[https://fmod.com/resources/documentation-api?version=2.0&page=core-api-channelgroup.html#channelgroup\_getchannel](https://fmod.com/resources/documentation-api?version=2.0&page=core-api-channelgroup.html#channelgroup_getchannel) the range specifies [0, ChannelGroup::getNumChannels]. Is that correct or is it supposed to be [0, ChannelGroup::getNumChannels)? It doesn’t seem like ChannelGroup::getNumChannels itself should be included given that it’s a count and not an index.

Thanks very much for pointing this out. You are correct and it’s not just `ChannelGroup::getChannel`, other get functions have this same mistake. I have created a task to fix all occurrences of this in the docs.
