Logic Pro 7.1 – Apple Loops (2005-0905) 2 of 23

Apple Loop Concept

A short History

The Apple Loop technology was not a straightforward development for Logic. Original developed for the application “

Soundtrack”

which was meant as

an audio postproduction tool or quick scoring tool for Final Cut Pro, it popped up in GarageBand and at the end in Logic. This explains the

inconsistency in labeling and file management.

1) Apple creates “

Soundtrack”

that introduces “Apple Loops”.

2) Utility “

Soundtrack Loop Utility

” comes with

Soundtrack

to create Apple Loops

3) Apple acquires Logic from Emagic

4) Apple takes some code from Logic and Soundtrack to create the consumer level sequencer “

GarageBand”

5) GarageBand is based on Apple Loops

6) Logic 7 gets support for Apple Loops. It ships with “

Apple Loops Utility

”, which is the same as “

Soundtrack Loop Utility

”

7) Logic 7.1 changes Apple Loop file management to conform with GarageBand

Identifying Apple Loops

You can’t identify an Apple Loop audio file just by looking at the file in the Finder. It looks like a regular aiff file with the “.aif” extension

However, if you drag the audio files into Logic then there will be the channel indication

• One circle: mono audio file or Apple Loop with the “File Type” tag set to “

One-Shot”

• Double circle: stereo audio file or Apple Loop with the “File Type” tag set to “

One-Shot”

• One ribbon: mono Apple Loop with the “File Type” tag set to “

Loop”

• Double ribbon: stereo Apple Loop with the “File Type” tag set to “

Loop”

Blue Apple Loops

vs Green Apple Loops

There are actually two kinds of Apple Loops: Blue and Green: (You can only see which one is which in the Loop Browser)

The Blue Apple Loops are the “regular” ones.

They include the audio data and the Apple Loop metadata, which enables the Time and Key matching when you place them onto an Audio

Track in Logic

The Green Apple Loops have two additional tags:

• MIDI data

• Channel Strip setting

You can place them on three different Tracks:

• Audio Track: they behave like blue Apple Loops with regular Time and Key matching

• MIDI Track: Logic ignores the audio data and instead will create a MIDI Region with the MIDI data which is part of the Green Apple

Loops metadata

• Audio Instrument Track: Logic will again ignore the audio data and create a MIDI Region with the MIDI data from the embedded MIDI

data. In addition, if the Audio Instrument Track doesn’t have any Instrument assigned yet, Logic will load the embedded Channel Strip

setting, which includes the Audio Instrument and any assigned inserts for that track.

NOTE: Once you placed them on one track type, it will become that region type (audio region or MIDI region) and you can’t move the Loop

i.e. from the audio track to the MIDI track to retrieve the MIDI data. You have to drag the Loop again from the Loop Browser direct onto a

MIDI track.
