jVSTwRapper is an easy and reliable Java wrapper for the Steinberg VST interface. It enables you to develop VST 2.4 compatible audio plugins and virtual instruments and user interfaces with the Java programming language. Three demo plugins (with source) are included.

Changes

This release introduces full LADSPA support: all VST effect plugins are automatically exported as LADSPA plugins as well. No additional configuration or anything else is required. Custom GUI support for Linux is available in this release. Java Swing GUIs can now be used as custom GUIs for Linux, Windows, and Mac OS X. A bug in the .ini file parser was fixed. Custom GUIs now works on Mac OS, but you need at least Java 1.5.0_06 installed on your system.
