Ahhh spectacular!

So yes I have the definition of Chorus correct. Thank you so much for the specific definition.

AND Charlie Fogel and AudioTrack, thank you so much for saying that the range for the volume change is accomplished by setting the on/off state at a certain bar of a certain chorus and then reversing or changing that setting at another bar of a certain chorus.

That means that the changes cover a SPAN of measures and the change does not have to be set for every bar in the Span. Really clear now.

Thanks for the rigor in your answer and solving for me the definitions, and the span of bars question. So helpful!!!
