NOT RELEASED YET NOT RELEASED YET NOT RELEASED YET NOT RELEASED YET NOT RELEASED YET

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:

  • Split (create new client and move capture ports to the the new client)
  • Join (move ports of one clients to another client and remove the first client)
  • New client
  • Move port
  • Rename client
  • Rename port
  • Remove (empty) client

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.

Download

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:

  • flowcanvas
  • LADI Tools
  • a2jmidid
  • jack2

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 http://ladish.org/ticket/187

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. Check the project goals for more info.

Project goals:

  • Save and restore sets of JACK (audio and MIDI) enabled applications.
  • Provide JACK clients with virtual hardware ports, so projects can be transfered (or backups restored) between computers running different hardware and backups.
  • Don't require session handling library to be used. There is no need of such library for restoring connections between JACK clients.
  • Flow canvas based GUI. Positions of elements on the canvas are saved/restored.
  • Allow clients to use external storage to save its state. This includes storing internal state to non-filesystem place like memory of a hardware synth. This also includes storing client internal state (client project data) in a way that is not directly bound to ladish project.
  • Import/export operations, as opposed to save/load. Save/load operate in current system and may cause saving data outside of project itself (external storage). Import/export uses/produces "tarball" suitable for transferring session data over network to other computer or storing it in a backup archive.
  • Hierarchical or tag-based organization of projects.
  • List of JACK applications. Applications are always started through ladish to have restored runtime environment closer to one existed before project save.
  • Distributed studio - network connected computers. Netjack configuration is part of the studio and thus is saved/restored.
  • Collaborate with the X11 window manager so window properties like window position, virtual desktop and screen (multimonitor) are saved/restored.
