Thank you Edward, it worked, made the file longer to slow the tempo!
One note I like to share, when I tried to use lastigue timestretch to use the pitch shift function at the same time, it lost the synch. However, when I used a different pitch shift effect at same time it functioned great!
Lastique timestretch has a check box to keep the body of the instrument function. The other pitch shift effect doesn’t, I changed other settings and used the EQ to get the result.
Thank you this will save me a lot of time and fix many files to my liking!
