AU Lab is a free audio suite that's part of Apple's Xcode package. It allows to works to several Audio Units and it's particularly handy as a fast way to host Virtual Instruments, especially if you're on a low end Mac or if you need a portable solution for your setup.
Moreover, it's very easy to set it up to run 32 bit plugins on newer versions of OS X, versions on whose can be difficult to find an appropriate build of GarageBand or Logic to do so.
Compatibility:
Tested on Mac OS X 10.6 Snow Leopard and 10.11 El Capitan, possibly runs n older systems.
