I've recently discovered that track delay times (ms/samples) reset to zero when you import a channel from one session into another. Please ensure that these values are not lost when the track is imported into a different session.
I've built a template set with dozens of orchestral sample instruments in which I meticulously applied negative delay values to each instrument so that their playback lands right on the grid and compensates for the lag in the instruments. However, these delay times default back to zero when I drag one of these template instruments from the browser into another session; undoing all of my prep work.
