XO Wave is a multi-track digital audio workstation for Mac OS X, complete with Video Synchronization, CD burning, and effects. Most modern Macs are compatible: XO Wave requires Mac OS X 10.4.4 ("Tiger") or Mac OS X 10.5.1 ("Leopard") or later, Java 1.5 (aka Java 5), 256mb RAM (512mb or more strongly recommended), a G4, G5 or Intel Processor and a 1024x768 or larger color display. The latest updates from Apple are strongly recommended. Mac OS X 10.5 "Leopard" is fully supported, but users are encouraged to read our Leopard compatibility notes on the XO Wave Website. Purchasing XO Wave entitles users to use XO Wave on a single machine.
