> Carla 2.0 RC2 is here!
On 2018-10-28 by falkTX

Hello everyone, this is the announcement for a Carla stable update.
Only 2 blocking issues remain, 1 of which needs testing to see if it still happens or not.

General fixes

  • Fix build against fluidsynth 2.0
  • Fix build on Haiku OS
  • Fix build with external plugins enabled but no OpenGL available
  • Fix detection of old Windows dll plugins
  • Fix dynamic/split process cycle for plugin bridges
  • Fix internal plugins receiving wrong frame position on split buffers
  • Fix program changes coming through as bank changes in MIDI output
  • Fix a possible race condition in plugin code
  • Fix some warnings triggered by gcc-8
  • Fix LV2 plugins with UI feedback ports in bridge mode not receiving feedback events
  • Fix macOS specific note visible in settings when not running macOS
  • libjack: Fix applications that register clients right after being started

Usability fixes

  • Always show keyboard in plugin edit dialog if plugin has midi inputs
  • Always expand user home path (~/) when loading project from CLI
  • Don't try to find binary type of certain plugins when loading project (avoid assertions)
  • Use executable basename on jack apps as name when initial name is empty
  • libjack: Catch window close when possible, and hide it instead closing entire application
  • libjack: Implement basic session management via SIGUSR1 signal


To download Carla binaries or source code, jump on over to the KXStudio downloads section.
If you're using the KXStudio repositories, you can simply install "carla-git" (plus "carla-lv2" and "carla-vst" if you're so inclined).
Bug reports and feature requests are welcome! Jump on over to the Carla's Github project page for those.


Work for KXStudio 18.04 ISO is under way, should only take a few more weeks now.
Next JACK2 release will be quite nice, we have meta-data now (thanks to Rui), but that will be handled after KXStudio 18.04 ISO release.
