Jalv

Jalv is a simple but fully featured LV2 host for Jack. It runs LV2 plugins and exposes their ports as Jack ports, essentially making any LV2 plugin function as a Jack application.

Jalv is a small program which is useful, but also intended to be an appropriate test host for plugin development. It runs plugins from the command line with no user interaction, is light enough to run in valgrind, and is capable of dumping all plugin to/from UI communication in a human readable format.

For testing with various host toolkits, there are several Jalv executables: jalv, jalv.gtk, jalv.gtkmm, and jalv.qt. The jalv and jalv.gtk programs are suitable for production use by users, the others are less complete and intended for developer testing only.

  9. Jack session (and LADISH, because it supports JACK session) has this feature where it can tell the application to save its state in a particular location. Is Jalv able to save the LV2 plugin settings in a location specified by the session manager and then load them later, from a location specified from the session manager?
