The VST to AudioUnit Adapter for Mac OS X is a highly-integrated plug-in wrapper that allows users of AudioUnit-compatible applications such as Emagic's Logic Audio 6.x and MOTU's Digital Performer 4.x to integrate VST plug-ins and instruments seamlessly in to their working environment. Once installed and configured, the wrapper creates "virtual AudioUnits" for each of your VST plug-ins, which behave exactly the same as true AudioUnits in every respect. It uses virtually no CPU (less than 0.1% per instance on a 550MHz PowerBook G4), and offers total compatibility with a huge selection of VST plug-ins from a wide range of vendors. It's also incredibly easy to use - just check out our step-by-step guide! We've tested the adapter succesfully with plug-ins from all the following vendors:- Steinberg, Waves, TC-Works, Prosoniq, LinPlug, MDA, reFX, Ohm Force, Synapse Audio, DSound, PSP, Waldorf, INA-GRM, Elemental Audio, Arturia, AAS, Bitshift Audio, Bitheadz, DMI, GMedia, Green Oak, Rumpelrausch Taips, Spectrasonics, Swar Systems, Yellow Tools, Silverspike, Destroyfx, Antares, DigitalFishPhones, Rob Papen Virtual Instruments.
Sounds like it should work.
