Subscribers to Apple's .Mac service last night received 100 free loops for GarageBand.

These are available for download now. Subscribers will find them in their "Members-Only" folder. The loops are taken from Apple's latest Jam Pack 4 for GarageBand: Symphony Orchestra. They include classical instruments such as brass sections, percussion, strings and woodwind sounds.

Members of the service already have access to 300 other sample loops taken from Apple's previous Jam Packs, 100 each from Jam Pack 1: Instruments, Loops, and Effects; Jam Pack 2: Remix Tools and Jam Pack 3: Rhythm Section.

These loops can be used on their own for iMovie soundtracks and other multimedia projects or mixed within GarageBand compositions.

The full boxed Jam Packs each containing hundreds of loops cost £65 each.
