USB Drivers for VariOS on mac OS X.

VariOS is an open-ended hardware/software system that can be customized for different needs. With the bundled V-Producer software, users can create audio-based arrangements while independently manipulating pitch, time and formant. Load the included VariOS-8 and VariOS 303 software, and VariOS can emulate some of Roland's most popular vintage synths—complete with an impressive array of effects. And since the VariOS module handles all processing, there is no drain on the host computer's CPU.
