Software Description

Jalv is a full featured LV2 host for Jack.

It runs LV2 Plugins turning them into Jack ports - making LV2 plugins function as Jack applications. Jalv is a useful tool for hosting and testing plugins that are under 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 easier testing of plugins in hosts that use different toolkits, there are several Jalv executables: jalv, jalv.gtk, jalv.gtkmm, and jalv.qt.

  • Show newly saved presets in the preset menu.
  • Generate Qt moc nonsense at build time for broader compatibility.

  • Update to waf 1.7.8 and autowaf r90

Changes in v1.2
