jBridge (often written as or JBridge ) is a specialized adapter software designed to "bridge" VST plugins. The tool uses inter-process communication to allow 32-bit plugins to run inside 64-bit hosts, and vice versa, effectively acting as a universal translator between your plugin library and your DAW. Originally developed by J's Stuff, it became an essential utility for producers who refused to let go of their legacy sound libraries.
: By running plugins as separate processes, jBridge allows 32-bit plugins to access more RAM than the standard 4GB limit of 32-bit hosts.
