Unfortunately, this does not work that way. I tried it starting with an existing comp from 6.05: recorded a new take, clicked on the main track (with comp tool or select tool); No return of the original comp. I also tried by creating a complete new comp with 4 new lanes (comp of three and then a new 4th take): No return of the original comp.
The only way to get the original comp back is by moving the last take out of the track to a new one. Now that defeats the whole purpose, ofcourse. Can someone verify? Or, if I’m too thick; clarify?
