I just purchased the New Magix Music Maker 2015 Premium and I have not been able to locate the "elastic audio" feature that I have become accustomed to using in previous 2013 version.  Has it been removed from the 2015 version?

Also, I have noticed a staggering occurence when I am attempting to record my audio vocals over my music track.  This makes it difficult to lay down my vocals when the music keeps sticking and staggering along the timeline.  Is there some magic fine tuning that needs to be implemented in the new 2015 Musiic Maker?

Please advise at your earliest convenience so that I can continue to evaluate my latest purchase of Music Maker 2015 Premium - Download Version to determine if it will serve my purposes for exercising my creative music compositions.
