ReConforming with Music?

Been Looking into switching from Cubase to Nuendo , Was wondering if anyone doing music has used the ReConforming when they have received a reel update ? I would normally just get a Dialog and Six audio track back with the new edit .

if you were to get a new EDL with any changes I wonder off the music / Midi side would also update and still be usable (with tweaks) in terms of beat and bar …

I guess mainly what happens to the Muisc grid side . tempo etc
