At the Macworld Expo earlier this month, Apple released its latest Jam Pack for Garageband, called "World Music." Apple notes that the collection contains 3,000 loops and 40 virtual instruments, but don't you wonder precisely what is included in these packages?

Don't worry about trying to comb through all of those loops and instruments yourself, for iCompositions has done it for you. Noting that the Jam Pack actually contains 3,235 Apple loops and 42 software instruments, they list them all, from the African Kalimba and the Irish Bouzouki to the Brazilian Sun Panderio and the Japanese Katana Flute. I'm just happy I'm not the one who had to compile this list.

MacJams.com, the music community for amateur and aspiring musicians, has released the 4th batch of free loops in their 5-week set. I posted this over on DownloadSquad, but I thought it was too cool to not mention here on TUAW. The loops are in Apple Loops format for the likes of GarageBand and (I think) Final Cut/Soundtrack. I've been too busy with a new semester to crack them open, but apparently they're just regular AIFF files any audio editing program should be able to use. In fact, one DLS reader was using in Sony's ACID Express on *shudder* Windows. I've also heard the loops touch on a range of sounds like ambient, hip-hop and jazz, so they sound pretty handy.

Go check the series out, especially since you have no excuse not to - they're free! They're also licensed for non-commercial use, and their site has more information on all that legalese. Enjoy!
