Thank you for your response. I am new at this so not sure if I am missing something in your explanation.
Normally I click New Sequence, locate the music for the sequence, once it has opened I click on Import Effects, select the free sequence I have saved, then the mapping window opens. I then map as close of models as I can then click save mapping. Then save the sequence in my own show folder.
What I believe you are saying is to just open the sequence I saved in my own show folder, select Import Effects, and map any other props. If so the problem is that the effects shown are the ones already assigned in my show (I attached a screenshot).
