The first milestone is reached and result is a tarball that brave souls
may want to download and try. It contains implementation of JACK
multiconfig functionality. JACK server settings can be saved as part of a
studio. Then, loading studio will cause JACK settings stored as part of
the studio to be restored.
Build will produce three operational components:
* ladishd - The daemon, a D-Bus service
* gladish - GTK GUI interface
* ladish_control - Command-line interface
In the tarball you will also find bundled suitable (latest and gratest)
flowcanvas and LADI Tools.
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
ladish has GUI frontend, gladish, based on lpatchage (LADI Patchage)
and the ladish_control command line app for headless operation. LADI
Tools is set of apps that interface with ladish, JACK server and
ladish requires D-Bus and JACK compiled with D-Bus support.
LADI Session Handler is rewrite of LASH.
* Save and restore sets of JACK (audio and MIDI) enabled
* 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
* 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
* 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
