jVSTwRapper is an easy and reliable wrapper to write audio plug-ins in Java. It enables you to develop VST (2.4), Audio Unit (AU) and LADSPA compatible audio plugins and virtual instruments plus user interfaces (Swing) and run them on Windows, Linux and Mac OS X. Five demo plugins (+src) are included.

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. This technology is a de facto standard for audio applications, and provides the richest set of functionality for audio plugin programming. jVSTwRapper therefore uses VST as the base technology and translates other audio plugin standards such as Audio Unit (AU) or LADSPA to VST by means of "native stubs".

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 and Mac OS X) and supports three plugin technologies (VST, AU, LADSPA) without any code changes or recompilation. Multi-platform plugins are created with a single command.

New in v0.9g

• Integrated with VSTAU, for Audio Unit support.
• Apache Maven integration: allows to create a .zip file from your jVSTwRapper plugin for all 3 supported platforms (Windows, Linux, Mac OS X) with a single command (again supported on every platform).
• Compilation and deployment of the wrapper itself is now also done via Apache Maven.
• Introduced a simple GUI to show/hide the plugin when window-embedding is turned off.
• Rewrote the GUI handling: greatly improved GUI stability on all platforms.
• Fixed parameter automation bug.
• Increased length of the ClassPath and other config entries that contain paths, now up to 5000 chars are allowed.
• Added automation support to the JayDLay example plugin.
• Fixed a tricky threading bug that crashed the JVM in very rare cases.
• New example VST instrument: LiquinthVST, a polyphonic synthesizer -- donated by Martin.
• Updated list of 3rd party jVSTwRapper users and projects on the website.
• Code cleanup.
• Performance improvements, esp. further minimized need for garbage collection.
