liquidsfz-0.4.2 has been released
The main goal of liquidsfz is to provide an SFZ sampler implementation
library that is easy to integrate into other projects. A standalone jack
client and a LV2 plugin is also available.
liquidsfz is implemented in C++ and licensed under MPL-2.0. The release
tarball can be downloaded here:

Overview of Changes in liquidsfz-0.4.2:
* File dialog updates:
- for bundled Ardour: restore environment variables to make file
dialog work
- fix yad arguments (use yad --file instead of --file-selection)
- replace some unsafe fork() based code with posix_spawn()
- use procfs on linux to safely read environment while host may modify it
* LV2Plugin: add midi keyboard widget, display switches and range/notes
- add API for querying Synth keyboard state
- add UI for drawing keyboard, make it fast to only draw if keys changed
* Support building with clang++ realtime sanitizer
* Support building with undefined behaviour sanitizer
* Update static build base to Ubuntu 22.04, g++-15
* Fixes:
- fix negative offset crashes
- use RTMutex in liquidsfz jack client to avoid RT unsafe std::mutex
- make frequency wrapping never stall audio thread for small loops
- avoid undefined behaviour for some float->int conversions (saturate)
- avoid undefined behaviour in Filter (nullptr addition)
- Loader::convert_uint: saturate values out of uint range, don't wrap
- avoid problems with very large playback frequencies (cap freqencies)
- minor build flags cleanups
- license of the LV2 plugin now says MPL-2.0
- add test to check flac support in static build
* Fixes after AI code review (#56):
- do not hold the plugin mutex while scheduling LV2 work (F01)
- keep LFO back-pointers valid when growing the voice vector (F03)
- stop all voices before unloading regions (F04)
- run queued JACK synth commands under the synth lock (F05)
- bounds-check UI program selection (F07)
- release mmap/fd resources even when opening a sound file fails (F08)
- make phase wrapping never stall audio thread (F09)
- remove hidden allocation from LFO modulation updates (F10)
- reject PEQ as a regular filter type (F11)
- allocate enough FFT output space in the resampling test tool (F12)
- transpose velocity-zero note-on only once (F13)
- apply octave offset to keyswitch lookup (F14)
- include key zero and preserve switch metadata (F15)
- reset sample selection on overrides (F16)
- initialize keyswitch / supported ccs arrays (F17)
- satisfy enlarged preload on cache hits (F19)
- handle filesystem lookup errors without exceptions (F20)
- use normalized Pugl mouse button indices (F21)
- handle UI initialization failures safely (F22)
- validate MIDI and state values and report save errors (F23)
- restore missing synthesis assertions (F24)
- preserve playback requests during eviction (I02)
- ignore bank define with empty variable names (I08)
