Session Management Overview

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.

ladish saves and restores connections to JACK apps without requiring session protocol support from them. This mode is also known as L0 (level 0). ladish can also use the JACK Session and LASH protocols. Additionally, there is also support for a minimalistic protocol known as "ladish L1". Here is a list of apps that support L1:

Other apps may have L1 support already implemented but not yet in a release (like Calf and Qsampler).

  • Fully compatible with JACK apps that have built-in support for LADISH, JACK Session or LASH
  • Not compatible with Non Session Manager protocol
  • Limited compatibility with apps without session manager support:
    • Some apps are programmed to save their current state when they receive the “SIGUSR1” Unix signal, and LADISH is able to send this signal to such apps. On receiving this signal, apps may then open a save file dialogue or save their state to a default file location. The user may need to load this state file manually after a session is restored
    • For apps which do not respond to the SIGUSR1 signal, LADISH is only able to restore their JACK connections
  • GUI frontend: Gladish, Claudia
  • Saving a session will save the state of all apps (except for those that cannot be prompted, one way or another, to save their state) plus the JACK connections of ALL apps
  • Opening a session will automatically launch all apps, restoring their state (if possible) plus their JACK connections
  • Apps which support LADISH, JACK Session or LASH can be told to save/load their state to/from a specific location
  • First released in 2009. Currently in active development
