Hi All, Just a note that I've extracted JNAJack (Java bindings for JACK) from the Praxis LIVE repository, along with other elements of the JAudioLibs code, and it's now on GitHub at https://github.com/jaudiolibs Should make it easier for people to work with (and contribute to!) the code. Downloads and other facilities are still on the Google Code site at http://code.google.com/p/java-audio-utils/ for now. Best wishes, Neil -- Neil C Smith Artist : Technologist : Adviser http://neilcsmith.net Praxis LIVE - open-source, graphical environment for rapid development of intermedia performance tools, projections and interactive spaces - http://code.google.com/p/praxis OpenEye - specialist web solutions for the cultural, education, charitable and local government sectors - http://openeye.info
