Once installed, the adapter is invisible to the user - plug-ins load and behave exactly like native AudioUnits, reaping the full low-latency benefits of Apple's advanced plug-in architecture. Thanks to its high-efficiency design, CPU overhead from the wrapper is so low as to be practically non-existent - less than 0.1% per instance on a 550MHz PowerBook G4.
FXpansion's Technical Director, Angus Hewlett, explains: "Apple's AudioUnit architecture is the leading next-generation plug-in architecture, and has many benefits. As the leading developer of plug-in adapter technology, we are ideally placed to offer a bridge to the huge selection of existing plug-ins in the Steinberg VST format. Our technology provides an unprecedented degree of integration - the VST plug-ins are converted 'on the fly' to true AudioUnits, and from the user's perspective behave identically to native AudioUnit plug-ins."
The VST to AudioUnit Adapter ships in April, and is available for preorder from FXpansion's web site at http://www.fxpansion.com , priced just $75.00 / Eu75,-- plus taxes where applicable.
