FluidSynth 2.1.6

FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution. FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps. Features Cross platform support (Linux, macOS and Windows to name a few) SoundFont 2 support SoundFont 3 support (vorbis-compressed SF2) Realtime effect control using SoundFont 2.01 modulators Playback of MIDI files Shared library which can be used in other programs Built in command line shell

2.1.604 Jan 2021 03:25 minor feature: Polyphony is ever exceeded, or. Voices are still playing while their SoundFont is being unloaded. a heap-based use-after-free.
2.1.414 Jul 2020 10:05 minor feature: an uninitialized memory access possibly triggering an FPE trap. Several regressions introduced in 2.1.3: Fluid_synth_start() failed for certain presets a NULL dereference in jack driver a stack-based overflow when creating the synth . Fluid_synth_start() failed for certain presets. a NULL dereference in jack driver. a stack-based overflow when creating the synth.
2.1.327 May 2020 13:05 minor feature: a cross-compilation failure from Win32 to WinARM. While fluid_player is seeking (#634, #646). a NULL pointer dereference if synth.dynamic-sample-loading is enabled. a NULL pointer dereference in delete_rvoice_mixer_threads(). a NULL pointer dereference in the soundfont loader. Dsound driver playing garbage when terminating fluidsynth. Avoid memory leaks when using libinstpatch.
2.1.207 Apr 2020 03:15 minor feature: Fluidsynth now exits with error when user-provided command-line arguments are out-of-range. Add verbose error logging to opensles and oboe drivers. a memory leak in oboe driver. a NULL dereference in the fluidsynth commandline program.
2.1.118 Feb 2020 13:25 minor feature: a regression introduced in 2.1.0 caused the jack audio driver to not correct a sample-rate mismatch. Pkg-config is now being to used to find readline. Various typos in the documentation. a memory leak in the file renderer. Leaking memory when sequencer clients were not explicitly unregistered. a heap-based use-after-free in jack driver. The linker possibly not finding libinstpatch.
2.1.001 Dec 2019 04:05 minor feature: an implicitly declared function caused a pointer to int truncation in CoreAudio driver. a stack-based overflow in CoreAudio driver.
2.0.915 Nov 2019 03:25 minor feature: an implicitly declared function caused a pointer to int truncation in CoreAudio driver. a stack-based overflow in CoreAudio driver.
2.1.0.rc128 Oct 2019 05:45 minor feature: Incorrect behavior of fluid_sample_set_sound_data(). Voices being mixed incorrectly, causing audible crackle esp. at sample-rates 48kHz. Make sure that defining NDEdisables assertions.
2.0.729 Sep 2019 03:15 minor feature: Broken audio output when reverb was active after synth creation. Deconsole messages not being visible for debuilds on Windows.
2.0.625 Sep 2019 21:39 minor bugfix: fix an uninitialized memory access, which could have led to NULL dereference or heap corruption in an out-of-memory situation fix a use-after-free when calling fluid_player_stop() fix the MIDI player not outputting any sound after stopping and restarting the playback (#550)
