MacJams.com has announced the opening of its new “Loop Store,” an online site where musicians can browse, listen to, and immediately download over 40,000 loops and sound clips. Loops can be purchased with credits costing as little as 40 cents each, and loops are available in a variety of formats for nearly any audio program for the Macintosh platform. To celebrate the grand opening of its Loop Store, MacJams is giving away 10 free 10-credit accounts and 10 free PowerFX Apple Loops Disc Jams CDs. Loops and audio clips for the Loop Store are professionally recorded and produced by PowerFX, which provides audio content to Apple, Sony Pictures, Propellerhead, and others.
