Splitting drum loops with Strip Silence

Product: Platinum, Gold
Version: 5, 6

Do you know the Strip Silence function in Logic? Strip Silence divides an audio region in smaller pieces and replaces the original region by these new slices in the Arrange window. Strip Silence is an excellent "destructive noise gate" for stripping unwanted side noise from a vocal or acoustical instrument track.

But have you ever used this function for splitting a drum loop and then changing the song tempo? This is what we will do in this tips and tricks thread.

Strip Silence works by detecting level. Detecting beats with this function will therefore work best when working with pecussive material with clearly defined beats. long cymbal sounds or the like will disturb the beat detection.

Stripping

Import a drumloop to the Arrange window and set the loop to match the tempo of the song.

Select the region and call up the Strip Silence window by pressing the default keycommand Ctrl+S. Tweak the threshold and other parameters until the loop is split accordingly. The preview will help you find the best settings for the particular loop.

After confirming with OK, the long drum loop of the Arrange window will be replaced by the smaller beat regions. If Strip Silence did not detect some loop split points, you will have to cut them by hand

The result are single beat regions that are fixedly bound to their bar position.

You may now increase or lower the tempo. The drumloop will stay in time.

For moving, copying, looping the new regions all together, they may be packed into a folder. Simply select all regions and hit the keycommand for Pack Folder (COMMAND+F), to be found as a menu command under Functions > Folder > Pack Folder.

This folder can now be handeled identically as any object in the Arrange window. You may copy or loop, shorten and split it. Double click the folder to open its content in a new Arrange Window. A double click on any free space inside this folder Arrange window will close the folder again.
