That's correct. I agree it would be as easy to put them on separate tracks and that would give you more control of each instrument. Also, in the past, I've explained this process to users rather write them out and each have forgotten how to get back to do it again. It is tucked away I'd say.

That said, for users that don't export to a DAW or have older versions of BIAB before Utility Tracks, this is a very good method to have additional instruments in their song project. Each of the original seven Legacy Tracks in the BIAB Mixer have this feature of a 10 track sub-mixer. There's nearly an unlimited way to configure these hidden sub-mixers for each track. The process is similar to old school analog punch-in or overdubs and there's no audio degradation as there was with tape recording.

It's also good for getting a quick rough mix when a user is looking to see how various instruments sound together and saves time by avoiding exporting a lot of tracks.

While I was playing around with my SGU, I also added the RT2495 Electric Piano, held chords, with the same settings as above, to the Pedal Steel Guitar Track and created a really cool sounding combo for that chord progression.
