Stretch and pitch shift audio files in real time. Take advantage of a library of audio and software instrument loops. Compose a first draft in GarageBand, then refine your piece with professional software. Logic Pro 7 now supports the Apple Loops file format that lets you work more efficiently and provide a better workflow than conventional file formats.

Pro Loops

First introduced in Soundtrack and later in GarageBand, Apple Loops have quickly gained popularity, with the huge range of professional sound libraries available. The inclusion of Apple Loops support in Logic Pro 7 brings the file format to a professional audio and MIDI production application for the first time.

Loops Browsing

Logic Pro 7 offers the Loop Browser for convenient searching. Based on the GarageBand browser, the Loop Browser lets you find Apple Loops by instrument, genre or mood. Logic displays search results as a listing that lets you easily preview the sound. When you add Apple Loops to your arrangement, Logic automatically transposes them to the right key and stretches them to the song tempo.

Software Instrument Advantage

If you choose Apple Loops in software instrument format, Logic inserts the corresponding instrument, effect and input settings. This whole channel facility saves far more data than a standard audio file and makes the swapping of loops from one song to another or sharing ideas with other musicians simpler and faster. Of course you can edit settings in the channel strip.

Apple Loops Utility

The Apple Loops Utility allows you to create your own Apple Loops from a simple audio file. You can add data to specify the attributes of the file, which will make it easy to find in the Loop Browser. The Apple Loops Utility also allows the addition of tags that describe the rhythmic elements of the audio file. This is achieved through analysis and transient detection of the audio file, resulting in a set of markers. You can also manually add markers or move existing markers to new locations. These markers provide a reference for Logic Pro 7, allowing realtime stretching of audio data.
