Re: [LAU] [ANN] LADI Session Handler - Preview 2

The second milestone is reached and result is a tarball that brave souls may want to download and try. It can start apps and restore their connections. Level 1 apps are supported. Beware that no apps have implemented level 1 yet. If non-level-1 app is started at level 1, it will probably quit on save, because the default signal handler for SIGUSR1 terminates the process. This preview also features a2jmidid support. Run the a2j script as an app in the studio. This is a beta quality software, use it with double caution. I would like to thank the early adopters and especially Frank Kober for their help with testing the git ladish code and for the valuable suggestions they gave. 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: * flowcanvas-0.6.0 * LADI Tools (svn version) * a2jmidid-6 (contains the a2j script for use in ladish) * jack2 from the ladi branch The jack2 ladi branch contains fixes for two important issues: * Race that causes connection restore to fail sometimes during studio startup (http://ladish.org/ticket/28) * A deadlock on studio start (http://ladish.org/ticket/35) Hopefully, these fixes with be in the next jack2 release (1.9.5). The jack2 ladi branch also contains the no-self-connect changeset that adds new engine option, for disabling self connect of apps. Default value for this option is to allow self connections. Make sure to configure jack2 with --dbus (and maybe with --classic too).

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. 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. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0> _______________________________________________ Jack-Devel mailing list Jack-Devel(a)lists.jackaudio.org http://lists.jackaudio.org/listinfo.cgi/jack-devel-jackaudio.org
