This is the home of the Ubuntu packages for the Pure programming language ( and related software, in particular: Grame's Faust (, Virginia Tech's Pd-l2ork (, as well as Jonathan Wilkes' latest and greatest cross-platform version of Pd-l2ork, Purr Data ( If you have any questions or bug reports concerning these, please contact me directly (see "Contact this user" in the sidebar) or via the Pure mailing list at

At present, the latest LTS packages are for Ubuntu 16.04 LTS (Xenial) and are available in the following PPAs:

- (Pure, Faust and dependencies)

- (Pd-l2ork, Purr Data and related Pure and Faust externals)

Please also check the other PPAs in the list below for packages for other Ubuntu versions. We generally try to support the latest two Ubuntu LTS versions as well as the current Ubuntu release. At the time of this writing these are Ubuntu 14.04 LTS (Trusty), Ubuntu 16.04 LTS (Xenial) and Ubuntu 17.10 (Artful).

PPAs for older Ubuntu versions may still be provided for some time, but they will not receive any more updates and will thus be outdated. These are marked EOL in the list below.
