Also note: the 64-bit operating system will effectively obsolete VST support, as their interfaces are written (almost always) in Carbon. Carbon libraries are not available to apps that are 64-bit clean. We are going down the 64-bit clean path, as every app eventually will, and Carbon.framework will be unavailable. So unless someone (Steinberg?) finds a way to update the VST libraries to not access Carbon.framework, update their headers to properly use the 64-bit memory access (does VST3 do this?) and to use Cocoa GUIs instead of Carbon (up to the individual developers), VST plugs are a dead end. Audio Units seem to be the only path forward. If someone could prove me wrong, we would really really like to know.

The VST 2 API is completely Carbon API free. It's just that in 32 bit it currently defines that the effOpenEditor opcode specifies that one of its parameter is a WindowRef. In 64 bit this will be defined to be a NSView pointer. That's all what it needs to get the VST 2 API into the 64 bit world on Mac OS X. And VST 3 supports from the beginning HIView and NSView based plug-in editors.
