Assuming I have two tracks, Track A and Track B, where Track A is a group of tracks, how do I solo Track B if it has a Gate effect with a sidechain that targets Track A? An example of this situation is shown in the image attached to this question. The project shown in this image is also available for download (sounds awful, but shows the problem).
In the given example, if Track B is soloed, then the Gate will no longer receive a signal because Track A stops sending a signal to the group. I could duplicate the group and create a ghost group, but that would incur significant CPU overhead in my real projects. Is there an efficient way to make this work?
