PHOTOSTORY DELUXE NEW VERSION NOW INCLUDING UP DATE SERVICE SO THINK ITS ABSOLUTE LATEST EDITION

I have read all help tutorials  gone on to u tube you name it

I used to be able to " with handles " on music line on an old magix system photo story 8  fade out certain music when it wasn't

appropriate for next photo or video

tried EVERYTHING on photo story  gone in to TIME LINE  which is where you could manually with " handles" taper off a piece of music or fade in a new piece of music so you didn't get a music track that ended severely

there is a tab on the system that mentioned music curve, thinking this was the answer , sadly not the case in fact it put a line on the

entire music  line that I cant remove nor do I know what it does

looked at all  you tube tutorials  to see if any one could help

pulled up the pdf file of all functions but couldn't see any info on this issue any one out there got a clue ??

I have windows 10 which is compatible with product
