[Mac-Dee]

hey guros

I have a remix i am doing and i have been given a vocal project with all the vocal arrangement its in 114 bpm and its not cut exactly to bars like really messy from another composer but the song is there and in time ..

i have done a instrumental in 110 bpm and want to know is there anyway to time stretch the whole group audio files at once or do i have to go through individually because with the way its edited will take agers cause its overlapping and all , just want to drop and drag and change temp
