Here's another example of what can be done with the Plugin/s.
If the Plugin had an option to start play when the DAW reached bar 256, so after it plays bar 255 in the first instance it will start play of bar 1 in the second instance with the rest of the song (that has this option checked). You could even add 255 to the bar numbers in instance 2 giving you the actual same bar numbers as the DAW.

Here is an example video with 2 Plugins, when the first on the left gets to bar 256 (17) then the second plugin starts on bar 256 (17) and continues to play seamlessly.
