If 32-bit compatibility is a consideration for you upgrading to Logic Pro X, or if, like me, you did upgrade and immediately lost hundreds of dollars in software because of developers not supporting 64-bit, rest assured that there are solutions. Sylenth1 running inside of Logic Pro X using Metaplugin in combination with jBridgeM. Sylenth1 bridged with jBridgeM loaded inside of Metaplugin. It’s a bit of a rabbit hole, but by taking the original 32-bit VST, wrapping it in 64-bit compatibility using jBridgeM, then finally wrapping that in Audio Unit compatibility for use inside of Logic Pro X using Metaplugin, the end result is an originally 32-bit VST plug-in now running stably inside of Logic Pro X, wrapped in 64-bit Audio Unit compatibility. Metaplugin is a "plug-in that loads other plug-ins. With Metaplugin, you can use VSTs inside of Logic Pro X and still have all of the available functionality that you have when using native Audio Units. Metaplugin is a plug-in that can host other plug-ins in this case our 64-bit VSTs that we just created using jBridgeM and want to use inside of Logic Pro X, which doesn’t support VSTs natively. In order to use the newly created 64-bit plug-ins, we would need some sort of Audio Unit plug-in that can load other plug-ins, allowing you to use a VST plug-in inside of the Audio Unit only Logic Pro X and that is exactly what Metaplugin from DDMF can do. The only downside-which you may have picked up on by the dialog wording inside of jBridgeM-is that it only supports VSTs and not Audio Units, which Logic Pro X uses exclusively.

Once jBridgeM has scanned your Mac it will give you a summary of the created files. Logic Pro X is 64-bit only, so select I'll be using a 64bit VST host.

While this was a utility Apple provided in Logic Pro 9, it was also a sign of where Logic Pro was headed 64-bit only.

With all the great new features included in Logic Pro X, there is one notable feature that has been dropped in this new version the 32-bit Audio Unit Bridge for running 32-bit plug-ins when using Logic Pro in 64-bit mode.

In this tutorial, I will show you how to use 32-bit plug-ins inside of Logic Pro X using two existing utilities on the market. Logic Pro X introduces a bunch of great new features and enhancements, including a full 64-bit only architecture to take advantage of all the benefits that 64-bit brings to audio production.
