padthv1 is based on the PADsynth algorithm by Paul Nasca, as a special variant of additive synthesis.

The software requirements for build and runtime are listed as follows:


Optional (opted-in at build time):


Latest release

2018-03-07 - The End of Winter'18 release.

Previous and older releases, including the change log, are also available here. You may also check out from the latest bleeding edge development source tree, using Git.

You can browse all files available for download, including binary packages, at padthv1 Files on SourceForge.net.


The installation procedure follows the standard for source distributions. In the extracted source directory, just do:

./configure [--prefix=prefix]


and optionally as root:

[sudo] make install

This procedure will end installing the following:

Just launch prefix/bin/padthv1_jack and you're off (hopefully). Note that the default installation path prefix is /usr/local.


padthv1 holds its settings and configuration state per user, in a file located as $HOME/.config/rncbc.org/padthv1.conf. Normally, there's no need to edit this file, as it is recreated and rewritten everytime padthv1 is run.


Plenty still, however padthv1 may be considered in beta phase already ;)


padthv1 is open source free software. For bug reports, feature requests, discussion forums, mailling lists, or any other matter related to the development of this piece of software, please use the Sourceforge project page.
