OK, I'll buy that. I've never used plug-ins so I guess I never missed turning it on, I just assumed that it would be there when needed. But what does the whole sentence mean? If it's turned on and you remove a plug-in that was on the track, does that mean that the track will no longer be lined up? Or, if you add a plug-in to a recorded track and that option is turned off, it won't compensate for the plug-in delay? Or something else?
