Logic's native plug-ins are part of the program and can not be used anywhere except in Logic itself There is version of the EXS24 sampler called EXSP24 and a version of the EVP88 called EVP73 which used to be for sale separately. Now that Logic Pro6 is the latest flavour, who knows? Check the Emagic website.... Regards - Colin
