A/B channel setting for entire channel - 0 load time

It would be great to be able to have an A/B channel where there is no plug-in load time or CPU pause. This would be done internally but keeping both A and B channels on and with audio routed to them, but of course, when A is on B is muted and vice versa.

This would be incredibly useful especially for stereo bus, but also just having two mixes of the same track.

It’s something that would also have to be able to be disabled so as to not use up CPU if not needed all the time, or just to be used when needed.

It would be cool if you could freeze both, or freeze individually and be able to switch between a frozen and unfrozen version.
