Tempo Sync All Your Audio In Logic Pro X

Dragging loops and audio recordings into Logic Pro that sync to your project’s tempo has always had limitations. You could always place the WAV loop at the start of a bar in Logic, then option-click-drag the bottom right to the correct bar length.
There’s always been Flex Mode too. However, anything other than very punchy drum loops and musical parts would often not lock up perfectly. Using Logic 10.4’s new “Smart Tempo” feature when dragging in loops and audio recordings of any length, you can almost always be sure it’ll snap to the bars and beats of your Logic project.
