FluidSynth 2.2.1

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

2.2.109 May 2021 17:25 minor feature: Make ALSA the default driver on Linux. Coreaudio driver failed to initialize on MacOS 11. WaveOut driver failed to initialize. COM initialization in WASAPI driver is no longer performed in the caller's context. WASPI driver now supports reverb and chorus. Handle SysEx GM/GM2 mode on, GS reset, and XG reset. Old behaviour of fluid_player_join has been restored to prevent infinite loop in client code. The Soundfont loader code has been refactored, illegal generators will now be skipped more consequently.
2.2.003 Apr 2021 03:16 minor feature: Support loading SoundFonts 2GiB on Windows. Major overhaul of the sequencer and its event queue Overlapping notes can be handled Performance improvement, since the event queue no longer blocks the rendering thread Time scale is not limited to 1000 anymore and can therefore be used for tempo changes . Overlapping notes can be handled. Performance improvement, since the event queue no longer blocks the rendering thread. Time scale is not limited to 1000 anymore and can therefore be used for tempo changes. The following audio drivers have gained multi-channel support DSound WaveOut . DSound. WaveOut. The WinMIDI driver supports multiple devices. Handle GS DT1 SysEx messages for setting whether a channel is used for rhythm part. Support use of UTF-8 filenames under Windows. Improved support for overriding tempo of the MIDI player. Handle settings-related commands in user command file before initializing other objects.
