Difference between Master Bus and Group Channel

Are their any differences? I’ve heard that the master bus may be processed differently than group channels, but I wanted to verify.

The reason is I typically add a group channel as a “pre master bus” where i add my mastering chain and add in reference mixes that I bus directly to the real master bus to bypass the mastering chain. I just wanted to make sure this wasn’t impacting anything. Thanks in advance guys!

Hi,

No, there is no difference. Apart from fact, you can route Groups to the Sends and also to multiple Outputs, but not the Output.
