- synth.note-cut has been introduced
\section NewIn2_4_0 What's new in 2.4.0?
- synth.device-id now has a default value of 16
- Default values of reverb and chorus settings have been tuned
- fluid_mod_get_transform() and fluid_mod_set_transform() for SoundFont 2.04 compliant modulators
\section NewIn2_3_2 What's new in 2.3.2?
- fluid_player_get_division() has been added
\section NewIn2_2_7 What's new in 2.2.7?
- Most getter functions of the MIDI event API are now const correct
- fluid_event_from_midi_event() has been added
\section NewIn2_2_0 What's new in 2.2.0?
- #fluid_file_callbacks_t <span style="color:red">now uses <code>long long</code> as file-offset type (see #fluid_long_long_t).</span><span style="color:red;font-weight:bold">This is a breaking change</span>, which allows to load SoundFonts bigger than 2GiB on Windows. This change required to bump fluidsynth's SOVERSION.
- <span style="color:red">various fluid_event_*() functions that received a "value" argument of type <code>short</code> now receive an <code>int</code> argument</span> in preparation for MIDI 2.0 support
- fluid_event_any_control_change() has been removed
- the sequencer has received a major revisal. For you that means:
- the sequencer's queue no longer blocks the synthesizer thread, due to being busy arranging its events internally.
- events that share the same tick was given a new, documented order, see fluid_sequencer_send_at().
- the sequencer's scale can now be used for arbitrary tempo changes. Previously, the scale of the sequencer was limited to 1000. The only limitation now is >0.
- there is now a dedicated event type for changing the sequencer's time scale, see fluid_event_scale().
- the dynamic-sample-loader has learned support to pin samples, see fluid_synth_pin_preset() and fluid_synth_unpin_preset()
- added getter and setter functions for individual effect groups
- support for UTF-8 filenames under Windows, see fluid_synth_sfload()
- MIDI Tempo of the fluid_player can now be overridden, see fluid_player_set_tempo()
- a per-tick callback has been added to the MIDI player, see fluid_player_set_tick_callback()
- WASAPI audio driver is now available on Windows
- the following drivers have gained support for new_fluid_audio_driver2():
- DSound
- WaveOut
- WASAPI
\section NewIn2_1_7 What's new in 2.1.7?
- a regression introduced in 2.1.0 prevented chorus from being audible when fluid_synth_process() was used
\section NewIn2_1_4 What's new in 2.1.4?
- a regression introduced in 2.1.3 broke fluid_synth_start() for DLS presets
\section NewIn2_1_1 What's new in 2.1.1?
- requirements for explicit sequencer client unregistering have been relaxed: delete_fluid_sequencer() now correctly frees any registered sequencer clients (clients can still be explicitly unregistered)
- using the sequencer with the system timer as timing source has been deprecated
\section NewIn2_1_0 What's new in 2.1.0?
- <span style="color:red">refrain from using fluid_synth_set_sample_rate()</span>
- \setting{synth_sample-rate} is no real-time setting anymore, see note about fluid_synth_set_sample_rate()
- new reverb engine
- chorus is now stereophonic
- smallest allowed chorus speed is now 0.1 Hz (previously 0.29 Hz)
- the following audio drivers were added:
- opensles
- oboe
- sdl2
- waveout
\section NewIn2_0_8 What's new in 2.0.8?
- fluid_sample_set_sound_data() caused broken sound when copying sample data
\section NewIn2_0_7 What's new in 2.0.7?
- fluid_free() has been added to allow proper deallocation by programming languages other than C/C++
\section NewIn2_0_6 What's new in 2.0.6?
- the MIDI player did not emit any audio when calling fluid_player_play() after fluid_player_stop()
\section NewIn2_0_5 What's new in 2.0.5?
- fluid_synth_process() omitted audio samples when called with arbitrary sample counts that were not a multiple of fluid_synth_get_internal_bufsize()
- fluid_synth_sfunload() was not releasing sample buffers of SoundFont3 files if \setting{synth_dynamic-sample-loading} was set to FALSE
\section NewIn2_0_3 What's new in 2.0.3?
- fix incorrect behaviour of fluid_sample_set_sound_data()
- add missing getters for midi events:
- fluid_midi_event_get_text()
- fluid_midi_event_get_lyrics()
\section NewIn2_0_2 What's new in 2.0.2?
- fluid_synth_error() has been deprecated, use fluid_set_log_function() to interfere log messages
\section NewIn2_0_0 What's new in 2.0.0?
FluidSynths major version was bumped. The API was reworked, deprecated functions were removed.
<strong><span style="color:red">Important changes that may not result in a compilation error but may cause your app to misbehave:</span></strong>
- all public \c fluid_settings_* functions that return an integer which is not meant to be interpreted as bool consistently return either FLUID_OK or FLUID_FAILED
- fluid_settings_setstr() cannot be used to set integer (toggle) settings with "yes" or "no" values anymore. Use fluid_settings_setint() instead, for example: <br /><code>fluid_settings_setint(settings, "synth.reverb.active", 0)</code> instead of <code>fluid_settings_setstr(settings, "synth.reverb.active", "no")</code>
- <span style="text-decoration:line-through;">explicit client unregistering is required for fluid_sequencer_register_client() and fluid_sequencer_register_fluidsynth()</span> (since fluidsynth 2.1.1 not required anymore, but still recommend)
- all public functions consistently receive signed integers for soundfont ids, bank and program numbers
- use unique device names for the \setting{audio_portaudio_device} setting
- fluid_synth_process() received a new more flexible implementation, but now requires zeroed-out sample buffers
<strong>Other changes in FluidSynth 2.0.0 concerning developers:</strong>
- all public \c delete_* functions return void and are safe when called with NULL
- the shell command handler was decoupled internally, as a consequence the param list of new_fluid_server() and new_fluid_cmd_handler() was adapted
- \c fluid_settings_set* functions no longer silently register unknown settings but return an error instead
- reverb: roomsize is now limited to an upper threshold of 1.0 to avoid exponential volume increase
- rename \c fluid_mod_new() and \c fluid_mod_delete() to match naming conventions: new_fluid_mod() and delete_fluid_mod()
- rename chorus getters to match naming conventions: fluid_synth_get_chorus_speed() and fluid_synth_get_chorus_depth()
- fluid_synth_remove_sfont() returns FLUID_OK or FLUID_FAILED
- introduce a separate data type for sequencer client IDs: #fluid_seq_id_t
- fluid_get_userconf() has been implemented for Windows
<strong>New Features and API additions:</strong>
- add \setting{midi_autoconnect} a setting for automatically connecting fluidsynth to available MIDI input ports
- add \setting{synth_overflow_important} and \setting{synth_overflow_important-channels} settings to take midi channels during overflow calculation into account that are considered to be "important"
- add \setting{synth_dynamic-sample-loading} a setting for enabling on demand sample loading
- add support for polyphonic key pressure events, see fluid_event_key_pressure() and fluid_synth_key_pressure()
- add fluid_synth_add_default_mod() and fluid_synth_remove_default_mod() for manipulating default modulators
- add individual reverb setters: fluid_synth_set_reverb_roomsize(), fluid_synth_set_reverb_damp(), fluid_synth_set_reverb_width(), fluid_synth_set_reverb_level()
- add individual chorus setters: fluid_synth_set_chorus_nr(), fluid_synth_set_chorus_level(), fluid_synth_set_chorus_speed(), fluid_synth_set_chorus_depth(), fluid_synth_set_chorus_type()
- add realtime settings for \setting{synth_reverb_damp} and \setting{synth_chorus_depth} parameters
- add seek support to midi-player, see fluid_player_seek()
- expose functions to manipulate the ladspa effects unit (see ladspa.h)
- add support for text and lyrics midi events, see fluid_midi_event_set_lyrics() and fluid_midi_event_set_text()
- complete rewrite of the soundfont loader API, see sfont.h
- support for 24 bit audio samples, see fluid_sample_set_sound_data()
- expose new_fluid_defsfloader() to support loading soundfonts from memory, see fluid_sfloader_set_callbacks() and <a href="fluidsynth_sfload_mem_8c-example.html">fluidsynth_sfload_mem.c</a>
- remove these structs from the public API and provide proper getter and setter functions instead:
- struct _fluid_sfloader_t
- struct _fluid_sample_t
- struct _fluid_sfont_t
- struct _fluid_preset_t
- add an additional general-purpose IIR filter, see fluid_synth_set_custom_filter()
- add a custom sinusoidal modulator mapping function, see #FLUID_MOD_SIN
- implement polymono support according to MIDI specs:
- add basic channel support, see fluid_synth_reset_basic_channel(), fluid_synth_set_basic_channel(), fluid_synth_get_basic_channel()
