LADI Session Handler - Version 1
(Nedko Arnaudov`s blog)

This release marks end of the preview series. It brings three new user visible features - virtual graph manipulation, LASH support and jack-session support.

Virtual graph manipulation allows to perform these operations:

The added LASH and jack-session support allows apps to be run in rooms at LASH or jack-session level. jack-session support requires jack-1.9.8.

The tarballs are available at the usual location:

There are two tarballs. ladish-1-with-deps.tar.bz2 is 5.3 MiB and bundles the major dependencies that are usually needed for running ladish:

All of these are either development (git/svn) versions or release versions that are patched to work better with ladish. The last released versions of these dependencies are expected work with ladish. The most serious "incompatibility" is that the jack2 mainline is missing the no-self-connect changeset. This changeset adds option to jack that allows prevention of jack apps self connection to "hardware" ports (usually system:playback_N). As such self-connecting apps are not rare at all, without it, the studio/room separation is not-effective and the workflow can get very confusing.

If you are compiling the software by yourself, then you should probably use this "fat" tarball.

The ladish-1.tar.bz2 tarball is 586 KiB and contains only ladish itself. It is expected to be used mainly by packagers.

Known issues
If you want to use yoshimi-0.060.10, beware that its jack-session implementation is broken. As a workaround, in gladish settings dialog, "JS delay" can be set to few seconds instead of the default 0. Two seconds should work in most cases. For more info, check

More info on the ladish project

LADI Session Handler or simply ladish is a session management system for JACK applications on GNU/Linux. Its aim is to allow you to have many different audio programs running at once, to save their setup, close them down and then easily reload the setup at some other time. ladish doesn't deal with any kind of audio or MIDI data itself; it just runs programs, deals with saving/loading (arbitrary) data and connects JACK ports together. It can also be used to move entire sessions between computers, or post sessions on the Internet for download.
