jVSTwRapper
It is a multi-platform, multi-plugin-technology project, grounded by VST technology.
The Steinberg VST interface technology is used and supported by a large variety of different audio applications on different platforms like Windows, Linux and Mac OS X.
jVSTwRapper therefore is a multi-platform, multi-plugin-technology project, grounded by VST technology. By providing native stubs for each platform and plug-in technology, a single jVSTwRapper plugin runs on three platforms (windows, linux, mac osx) and supports three plugin technologies (VST, AU, LADSPA) without any code changes or recompilation. Multi-platform plugins are created with a single command ([here] is more info).
