On 2022-09-30 by falkTX

Hello again everyone, a new Carla release is here, v2.5.1 which brings a couple of fixes to the v2.5 series.

Carla is an audio plugin host, with support for many audio drivers and plugin formats.
It has some nice features like automation of parameters via MIDI CC (and send output back as MIDI too) and full OSC control.


  • Do not set scale factor for LV2 plugin UIs on macOS
  • Fix external MIDI connections for JUCE engine driver
  • Fix a few memory leaks and runtime issues
  • Fix several race conditions
  • Fix logic around engine driver listings
  • Fix position of external patchbay graph nodes not being restored when switching from internal to external
  • Fix RISC-V builds
  • Fix win32 bridge builds on win64 systems (forcing usage of i686-w64-mingw32 if needed)
  • Ignore some compiler warnings from Qt side
  • Use an outer frame for carla-lv2 outgoing events
