Apple has released two additional Jam Packs for GarageBand.

Jam Pack 2: Remix Tools offers loops and sounds to help build dance, hip-hop and electronica tracks; while Jam Pack 3: Rhythm Section offers the music users may need to build rock, alternative and country music sounds.

Apple’s vice president of applications marketing, Rob Schoeben, said: "GarageBand and the original Jam Pack made it possible for anyone, regardless of their musical background, to easily create great sounding music on their Mac. With these two new Jam Packs, musicians and aspiring musicians can delve deeper into their favorite genre. GarageBand just got better.”

Jam Pack 2: Remix Tools

Remix Tools provides 2,000 additional loops, 20 new beat kits (Techno, R&B, House and Trance), new synthesizer and sound effect instruments and classic drum machines from Roland (including the TR-808, TR-909, TR-606 and CR-78).

Jam Pack 3: Rhythm Section

Rhythm Section adds 2,000 loops and 50 new instruments. These include new drums - jazz, indie, warehouse; basses (Motown, Liverpool, Progressive Rock, Unplugged) and guitars (Dobro Slide, Bluegrass Banjo, Bluesy Acoustic, Heavy Metal Electric).

GarageBand also wins a celebrity endorsement, from Barenaked Ladies guitarist and singer Ed Robertson: “The instruments and loops in the new Jam Pack 3: Rhythm Section sound incredibly realistic and natural - even acoustic and folk instruments, which are typically difficult to recreate on a computer.”

System requirements include: Mac OS X 10.2.6 or later, QuickTime 6.4 or later, a 600 MHz or faster G3, G4, or G5 processor-equipped Mac, 256MB or more RAM and a 1,024x768 or larger display. A G4 or G5 processor is required for GarageBand software instruments.

The new Jam Packs cost £69.
