Zebra is a next-generation virtual synthesizer plug-in. It combines subtractive and additive synthesis with a powerful modulation engine that even smoothly integrates with the built-in effects section. The Audio Units version for MacOS X will be available to musicians with fastidious sound requirements in December 2003.
Zebra will cost only 159$ (US)! - But as a special pre-order offer, users can save almost 50% by purchasing this now.
