Time base = change ALL at once


how can you toggle all your tracks to Linear or Musical Timebase ?
Sometime i search for ideas without listening to the clic. Then i want to work that idea on tempo and i change the BPM of the session… but all tracks change speed according to this. The only way is to select the tracks i was working with and manually toggle them to linear, change tempo, toggle to musical again.

isn’t there a way to change all track at once ?
also sometime you want to copy paste parts to another part that hase another tempo but you want to keep the speed of the first… you can’t do that without clicking dozens of tracks multiple times.

is there a way ?
