1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
6     - Added support for sfz extension opcode 'script' which may be used to
7     load real-time instrument script file (NKSP script language).
8 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 2856
11 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
12 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13     cutoff settings.
14    
15 persson 2837 * general changes:
16     - fixed printf type errors (mostly in debug messages)
17 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
18 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19     allowing to sort data efficiently in real-time safe manner.
20     - RTList class: added methods for moving/inserting elements to arbitrary
21     position within a list.
22     - RTList class: added method fromPtr() for creating an Iterator object from
23     a raw element pointer.
24     - Attempt to partly fix resetting engine channels vs. resetting engine, an
25     overall cleanup of the Reset*(), ConnectAudioDevice(),
26     DisconnectAudioDevice() API methods would still be desirable though,
27     because the current situation is still inconsistent and error prone.
28 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
29     being directly assigned to a keyboard key. This allows more fine graded
30     processing of voices, which is i.e. required for certain instrument
31     script features.
32 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
33     (CC #64) events.
34     - Fix: Release trigger voices can now also distinguish correctly between
35     note-off and sustain pedal up events.
36 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
37     (while slow rate of crossfade smoother is preserved) to allow quick
38     volume and pan changes by instrument scripts for instance.
39 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40     properly and thus were ignored for certain uses.
41 schoenebeck 3018 - Added new C++ API method
42     VirtualMidiDevice::SendChannelPressureToSampler().
43 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
44     sub threads is 16-byte aligned
45 schoenebeck 3054 - fixed numerous compiler warnings
46 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47 persson 2837
48 schoenebeck 2866 * packaging changes:
49     - removed unnecessary dependency to libuuid
50     (originated by libgig's usage of it)
51 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52     auto detect whether it (sh/c)ould output its messages in color.
53 schoenebeck 2866
54 schoenebeck 2871 * Real-time instrument scripts:
55     - Implemented scheduler for delayed MIDI events and for suspended scripts.
56     - Built-in script function "wait()": implemented support for function's
57     "duration-us" argument, thus scripts using this function are now
58     correctly resumed after the requested amount of microseconds.
59     - Built-in script function "play_note()": implemented support for
60     function's "duration-us" argument, thus notes triggered with this
61     argument are now correctly released after the requested amount of
62     microseconds.
63     - Fix: script events were not cleared when engine channel was reset,
64     potentially causing undefined behavior.
65     - Fixed crash which happened when trying to reference an undeclared
66     variable.
67 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
68     special value -1 for "duration-us" argument, which will cause the
69     triggered note to be released once the original note was released.
70 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
71     - Added new API method ScriptVM::syntaxHighlighting() which provides
72     a convenient syntax highlighting backend for external instrument
73     script editor applications.
74 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
75     - Extended parser issues to provide not only first line and first
76     column, but also last line and last column of issue (thus marking
77     the precise span of the issue within the source code).
78 schoenebeck 2902 - Reload script automatically after being modified by an instrument
79     editor.
80 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
81     like "on note end on".
82 schoenebeck 2931 - Implemented built-in script function "change_vol()".
83     - Implemented built-in script function "change_tune()".
84     - Implemented built-in script function "change_pan()".
85 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
86     - Implemented built-in script function "change_reso()".
87     - Implemented built-in script function "event_status()".
88     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90     "event_status()" function.
91     - NKSP language: Added support for bitwise operators ".or.", ".and."
92     and ".not.".
93     - NKSP language scanner: Fixed IDs matching to require at least one
94     character (i.e. when matching function names or variable names).
95     - NKSP language scanner: disabled unusued rules.
96 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
97     be distinguished engine internally from "real" MIDI note on/off
98     events in order to avoid misbehaviors like hanging notes.
99 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
100     - Implemented built-in script variable "$NKSP_REAL_TIMER".
101     - Implemented built-in script variable "$NKSP_PERF_TIMER".
102     - Implemented built-in script variable "$ENGINE_UPTIME".
103 schoenebeck 2945 - Implemented built-in script function "inc()".
104     - Implemented built-in script function "dec()".
105     - NKSP language fix: division expressions were evaluated too often.
106     - NKSP language fix: string concatenation operator was right
107     associative instead of left (to right).
108 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
109     (i.e. "if end if").
110 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
111     - Implemented built-in script variable "$NI_CALLBACK_ID".
112     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114     - Added support for read-only built-in variables (respectively
115     handled by the script parser).
116     - Added built-in script constant "$NI_CB_TYPE_INIT".
117     - Added built-in script constant "$NI_CB_TYPE_NOTE".
118     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

121 schoenebeck 2953 - Implemented built-in script function "change_attack()".
122     - Implemented built-in script function "change_decay()".
123     - Implemented built-in script function "change_release()".
124 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
125     synthesis parameter changes immediately in case the respective note
126     was triggered at the same time, instead of scheduling the parameter
127     change, especially because it would cause some parameter types's
128     changes either to be ramped (i.e. change_vol()) or other types even
129     to have not effect at all (i.e. change_attack()).
130 schoenebeck 2965 - Implemented built-in script function "sh_left()".
131     - Implemented built-in script function "sh_right()".
132 schoenebeck 2970 - Implemented built-in script function "min()".
133     - Implemented built-in script function "max()".
134 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
135     was loaded.
136     - NKSP built-in wait() script function: abort script execution if
137     a negative or zero wait time was passed as argument (since this is
138     a common indication of a bug either of the script or even of the
139     engine, which could lead to RT instability or even worse).
140 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
141     threatening scripts.
142 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
143 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
144     initializer list to an array variable.
145 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
146 schoenebeck 3076 - Implemented built-in script function "in_range()".
147 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
148     - Implemented built-in script function "change_amp_lfo_freq()".
149     - Implemented built-in script function "change_pitch_lfo_depth()".
150     - Implemented built-in script function "change_pitch_lfo_freq()".
151 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
152     - Implemented built-in script function "change_tune_time()".
153     - Implemented built-in script function "fade_in()".
154     - Implemented built-in script function "fade_out()".
155     - Fixed acceptance of wrong data type of parameters passed to built-in
156     script functions "change_vol()", "change_tune()", "change_pan()",
157     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
161     of its possible parameter selections.
162     - Added built-in script function "set_event_par()" and implemented some
163     of its possible parameter selections.
164 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
165 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
166 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
167     built-in function "ignore_controller()".
168 schoenebeck 3214 - Implemented built-in script function "change_velo()".
169     - Implemented built-in script function "change_note()".
170 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171     intuitive behavior if used in combination with "change_vol_time()" or
172     "change_tune_time()" respectively: now tuning/volume changes are only
173     assigned (without delay) immediately to a new note if the respective
174     timing function has not been called before, otherwise the volume/tuning
175     changes are automatically faded (before, only the event's time stamp was
176     relevant).
177 schoenebeck 3221 - Implemented built-in script function "array_equal()".
178     - Implemented built-in script function "search()".
179     - Implemented built-in script function "sort()".
180     - NKSP Fix: Never suspend "init" event handlers.
181 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
182     available for gig format engine).
183 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
184     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
185     - Implemented built-in script function "change_vol_curve()".
186     - Implemented built-in script function "change_tune_curve()".
187 schoenebeck 2871
188 schoenebeck 3050 * Instruments DB:
189     - Fixed memory access bug of general DB access code which lead to
190     undefined behavior.
191 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
192     - The instrument DB path of linuxsampler's --create-instruments-db argument
193     is now optional, if it is missing, then a default location is used.
194 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
195     - Added support for scanning Sound Font (.sf2) files.
196 schoenebeck 3101 - Fixed undefined DB transaction behavior.

234 persson 2519 - enabled automake 'subdir-objects' option and moved external
235     source references (vst, au, asio) from makefiles to cpp files,
236     in order to get rid of warnings from automake 1.14
237 persson 2382
238 persson 2086 * general changes:
239 iliev 2012 - Refactoring: moved the independent code from
240     the Gigasampler format engine to base classes
241 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
242     respective profiling code is currently broken
243 schoenebeck 2053 - Introduced support for optional environment variable
244     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
245     where the sampler shall look for instrument editor plugins
246     (patch by Luis Garrido, slightly modified).
247 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
248     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
249     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
250     note (in this implementation of the sampler its simply hard routed to
251     the 1st effect send of the sampler channel, no matter what the actual
252     effect type is)
253     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
254     note (in this implementation of the sampler its simply hard routed to
255     the 2nd effect send of the sampler channel, no matter what the actual
256     effect type is)
257 schoenebeck 2124 - implemented support for internal LADSPA effects
258 schoenebeck 2140 - raised limit of program change queue from 100 to 512
259     (as suggested by Alex Stone)

261 iliev 2296 - experimental support for per voice equalization
262 iliev 2306 - added command line option --exec-after-init
263 schoenebeck 2330 - Introduced new C++ API method:
264     EngineChannel::InstrumentFileName(int index)
265     allowing to retrieve the whole list of files used for the loaded
266     instrument on an engine channel (a.k.a. part). Some GigaStudio
267     instruments for example are splitted over several files like
268     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
269 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
270     - Added new C++ API method Sampler::GetGlobalMaxStreams().
271     - Added new C++ API method Sampler::SetGlobalMaxVoices().
272     - Added new C++ API method Sampler::SetGlobalMaxStreams().
273 schoenebeck 2377 - Various "const" and "restrict" optimizations.
274 persson 2382 - all engines: add pan CC value to instrument pan parameter before
275     applying panning, instead of using two separate pan functions in
276     series (#182)
277 persson 2427 - added a lock guard class for exception safe mutex handling and
278     used it everywhere appropriate
279 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
280     - Exposed scale tuning to C++ API (along to the already existing standard
281     SysEx way).
282 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
283     and broken for ppc64. (Seq_cst loads and stores are actually not
284     used in LS, so the bug wasn't noticable.)
285     - lsatomic.h: added ARMv7 support
286 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
287     added various new C++ methods for this new feature / design change, old
288     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
289     as deprecated but are still there and should provide full behavior
290     backward compatibility).
291     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
292     unsafe and caused compilation error with clang 2.x).
293 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
294 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
295     sampler from the command line by providing LSCP aware features.
296 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
297     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
298     - VirtualMidiDevice: Added support for pitch bend.
299 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
300     polyphonic key pressure events (so far polyphonic pressure was not
301     supported at all, and channel pressure was rerouted as CC128 but not
302     used so far).
303 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
304     code is shared by all sampler engine implemementations, however only the
305     gig file format currently provides support for storing instrument scripts
306     (as LinuxSampler extension to the original GigaStudio 4 format).
307 iliev 2012
308 persson 2043 * Gigasampler format engine:
309     - implemented the "round robin keyboard" dimension
310     - fixed round robin and random dimensions for cases when number of
311     dimension zones is not a power of two
312     - made round robin use a counter for each region instead of each
313     key
314 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
315     - bugfix: filter keyboard tracking was broken
316     - filter performance fix (an unnecessary copy was made of the
317     filter parameters in each sub fragment)
318     - handle special case when pan parameter in gig file has max or
319     min value
320 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
321     doesn't sound naturally with a drumkit
322 persson 2408 - fixed EG1 modulation when attack or release is zero
323 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
324 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
325     conditions (see also previous commit on libgig).
326 persson 2673 - fixed behaviour of filter LFO
327 persson 2043
328 schoenebeck 2047 * SFZ format engine:

345 persson 2082 - added support for amp_veltrack and amp_velcurve_N
346     - fine-tuned the default velocity curve
347 persson 2086 - added support for transpose
348     - fixed crash when using sw_down/up
349     - improved logic for sw_lokey/hikey/up/down/last
350     - added more v1 aliases to parser
351 persson 2091 - reduced memory usage for sfz data

690 iliev 2201 - fixed crash which occurred when changing an already deployed sampler
691 schoenebeck 2123 channel to a different engine type
692 persson 2127 - fixed crash when deleting a sampler channel or changing engine
693     type while an instrument load was in progress
694 persson 2162 - bugfix: playing a note while changing the instrument could cause
695     a crash, or give "Handing back unknown region" error messages
696 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
697     refresh) could cause instruments to be unloaded

699     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
700 persson 2185 - Mac OS X: fixed hanging threads
701 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as

703 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
704     after MIDI/audio device creation failure
705 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
706     instruments were uselessly precached with zero samples, however it still
707     took the full preloading time and on 1st program change the respective
708     instrument was completely reloaded again.
709 persson 2277 - fixed handling of rapid bank select and program change messages
710     sent to the same sampler channel (patch from the Open Octave
711     project, slightly adjusted)

728     (labelled "Disk stream not available in time")
729 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
730     crashes and noise on such transitions).
731 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
732     (fixes #208)
733 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
734     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
735     practically irrelevant, however it caused problems with the new LSCP
736     shell's auto completion feature).
737 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
738     after each other (fixes #231).

741 schoenebeck 1599
742 schoenebeck 1639 * packaging changes:
743     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

775 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
776 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

788 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
789     be switched on by command line option "--stacktrace" (the automatic
790     stacktrace mechanism seems to be broken on most systems at the moment)
791 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
792     a pointer to the launched InstrumentEditor object
793 schoenebeck 1876 - added optional 3rd party user data parameter for following
794     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

811     reflected the wrong value
812 persson 1644 - fixed a memory management bug in ASIO driver
813 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

815 persson 1748 jack_client_new
816 iliev 1829 - added (experimental) CoreAudio driver
817 persson 1888 - applied old fixes to the ASIO driver that were included in the
818     previous binary release but accidentally never committed to CVS
819     (fixes #117)
820 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
821     win64)
822 persson 1895 - VST: added support for sample rate and buffer size changes

830     stored in the plugin state
831 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
832     AudioChannel::CopyTo() methods using GCC vector exensions
833     (if available)
834 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
835     exception when getting parameters from a disconnected device
836 schoenebeck 1599
837 persson 1651 * MIDI driver:
838     - added JACK MIDI driver
839 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
840     want to (mis)use it for some purpose ("fixed" in all current MIDI
841     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
842 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
843 persson 1887 CoreMidi or AU
844 persson 1889 - fixed mingw-w64 compilation error in MME driver
845 persson 1924 - made program change handling in MIDI thread real-time safe by
846     moving the logic to a non-RT thread
847 persson 1951 - fixed minor memory leak in ALSA driver
848 persson 1651

856 persson 1908 - work-around for missing fnmatch function on Windows to make
857     instrument database compilable
858 schoenebeck 1930 - added instrument database support on Windows
859     works with both standalone mode and VST plugin.
860     the instruments DB file is located in
861     %USERPROFILE%\.linuxsampler\instruments.db which allows different
862     databases for each windows user
863     if no DB is present it automatically creates the .linuxsampler subdir
864     and then creates an empty DB
865 persson 1943 - fixed recursive import, which was broken on Windows
866 iliev 1603
867 persson 1644 * Gigasampler format engine:
868     - fixed a memory leak that could happen when a channel was deleted
869     while notes were playing
870 persson 1646 - made it possible to load an instrument even if the audio thread
871     isn't running
872 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
873     enough for piano gigs with pedal noise samples
874 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
875     respective FX send MIDI controller was used
876 schoenebeck 1724 - added support for GM global device volume SysEx message
877 schoenebeck 1762 (can be selected at compile time to either apply globally to the
878     whole sampler [default] or only to the sampler channels that are
879     connected to the respective MIDI input port the SysEx message arrived
880     on)
881 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
882     sometimes wrongly killed in the same buffer, causing no sound to
883     be played
884 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
885     which is usally used to switch a part between chromatic sounds and
886     drumkit sounds (as opposed to their common default setting of MIDI
887     part 10 being a drumkit part and all other ones chromatic parts), in
888     LS however one can switch between the first 16 MIDI instrument maps
889     defined for the sampler
890 persson 1764 - made it possible to create multiple sample channels even if the
891     audio thread isn't running
892 persson 1844 - fixed crash when removing channel with active voices (#116)
893 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
894     un-cache the respective sample if it's really not used by any
895     sampler engine anymore
896     - re-cache samples in case they were changed by an instrument editor,
897     e.g. when a sample was added while playing (#82)
898 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
899     same time stamp as the voice's note-on event and occured both in the
900     same audio fragment cycle (fixes bug #112)
901 persson 1858 - added support for the "fine tune" and "pitch bend range"
902     instrument-level gig parameters
903     - fixed minor artifacts in pitch bend handling
904 schoenebeck 1860 - added support for GS Reset SysEx message
905 persson 1862 - allow gig files to use unlimited downward pitch shifting
906     - added a limit check for upward pitch shifting
907 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
908     note was silent
909 persson 1923 - fixed crash happening when a pitch bend event arrived at the
910     same time a new instrument was loading
911 persson 1644
912 schoenebeck 1687 * LSCP server:
913     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
914     react on MIDI data arriving on certain sampler channels (so far only
915     Note-On and Note-Off events are sent via this LSCP event)
916 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
917     react on MIDI data arriving on certain MIDI input devices (so far only
918     Note-On and Note-Off events are sent via this LSCP event)
919 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
920     SET DB_INSTRUMENT FILE_PATH
921 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
922     frontends to send MIDI messages to specific sampler channel
923     - added two additional fields to GET FILE INSTRUMENT INFO command -
924     KEY_BINDINGS and KEYSWITCH_BINDINGS
925 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
926     was incorrect
927 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
928 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
929     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
930     be triggered respectively
931     - added new LSCP command "SET STREAMS" to globally alter the maximum
932     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
933     which will be triggered respectively
934 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
935     a gigedit file dialog is opened)
936 iliev 1848 - close all connections when LSCPServer is deleted
937 iliev 1882 - hard close of all sockets on exit
938 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
939     driver
940 schoenebeck 1687
941 iliev 1761 * Bug fixes:
942     - fixed a crash which occurs when removing a sampler channel waiting
943     to start instrument loading after another channel
944 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
945     instrument loading in progress (bug #113)
946 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
947     instrument with PERSISTENT load mode
948 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
949     - fixed memory leaks when issuing the following LSCP commands:
950     GET AUDIO_OUTPUT_DRIVER INFO
951     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
952     GET MIDI_INPUT_DRIVER INFO
953     GET MIDI_INPUT_DRIVER_PARAMETER INFO
954     - fixed possible compilation error when sqlite is not present
955 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
956 iliev 1847 - fixed crash when changing the audio output device of a sampler
957     channel with loaded instrument and start playing notes
958 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
959 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
960     PowerPC, which probably could cause crashes on that platform
961 persson 1889 - fixed a memory management error which could cause a crash when a
962     plugin was unloaded
963 persson 1896 - bugfix: two private structs had the same name, which could cause
964     problems if the linker chose the wrong constructor
965 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
966     Windows
967 iliev 1761
968    
969 schoenebeck 1560 Version 0.5.1 (6 December 2007)
970 schoenebeck 1454
971     * packaging changes:
972     - added autoconf checks for pthread library
973     - added autoconf check for pthread bug found on certain NPTL-enabled
974     glibc versions (see Gentoo bug report #194076)
975 senoner 1502 - added autoconf checks for MS Windows
976 schoenebeck 1454
977 persson 1455 * general changes:
978     - bugfix: the thread used by an editor plugin didn't die when the
979     editor closed
980 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
981     out all the space. operator--() did not apply size_mask after
982     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
983     order to avoid problems with the _NonVolatileReader functions.
984     - bugfix: Stream.h: added a missing divide by BytesPerSample in
985     GetWriteSpace(). Since this function is currently only used in
986     the stream's qsort() compare function, it didn't trigger any
987     bugs.
988     - Resampler.h, Synthesizer.h: cubic interpolation now works in
989     24bit mode too. Faster method to read 24bit words on little
990     endian machines (x86): replaced 3 byte reads + shifts with a 1
991     unaligned 32bit read and shift
992     - experimental support for MS Windows (MIDI input via MME, AUDIO
993     output via ASIO)
994     - made handling of SIGINT signal (Ctrl-C) a bit more robust
995 iliev 1541 - support for monitoring the total number of active disk streams
996     (new LSCP commands: GET TOTAL_STREAM_COUNT,
997     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
998 persson 1455
999 senoner 1500 * AUDIO driver:
1000 persson 1534 - added Windows ASIO low latency audio driver
1001 senoner 1500
1002 senoner 1485 * MIDI driver:
1003 schoenebeck 1495 - added MME Windows MIDI driver
1004 senoner 1485
1005 schoenebeck 1471 * LSCP server:
1006     - added support for Windows style path / filenames, however with
1007     forward slash path separators instead of backslash
1008     (i.e. "C:/foo/bar.gig")
1009 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1010     apostrophes as well
1011 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1012     "LIST FILE INSTRUMENTS <file>" and
1013     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1014     about an arbitrary instrument file on the system where the sampler is
1015     running on
1016 schoenebeck 1471
1017 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1018 schoenebeck 947
1019 schoenebeck 1065 * packaging changes:
1020 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1021     API header files anymore
1022 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1023     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1024 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1025     capable to execute our autoconf environment, thus no need anymore
1026     to maintain the compile time configuration file (osx/version.h) for
1027     OSX manually (patch by Toshi Nagata)
1028 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1029     parameters
1030 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1031     C++ API header files, all implementation internal global definitions
1032     are now in global_private.h
1033     - atomic.h is not exposed to the C++ API anymore
1034     - no need to include config.h anymore for using LS's API header files
1035     - fixed warnings in API doc generation
1036 schoenebeck 1065
1037 schoenebeck 947 * general changes:
1038     - replaced the old, confusing MIDI program change mechanism by a
1039     flexible MIDI instrument mapper which allows to map arbitrary
1040 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1041 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1042     loaded on the respective channel when such MIDI program change
1043     messages arrive, beside that, each entry allows to define a life-time
1044     strategy for the instrument, so the user can define whether the
1045     instrument should i.e. be permanently loaded (to be able to switch
1046     quickly among sounds) or i.e. loaded just on demand when the
1047     respective program change arrives (to safe RAM space), as well as a
1048     global volume factor for each entry, so the user can adjust the volume
1049     dynamic of his mapped instrument collection without having to modify
1050 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1051     MIDI instrument maps and assign each sampler channel individually
1052     a certain map, so that i.e. separation of normal instruments and
1053     drumkits is possible
1054 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1055     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1056 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1057     due to a constant size RingBuffer FIFO which is now replaced by a
1058     dynamic (unlimited) size std::list FIFO
1059 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1060     output channels for being processed by external effect processors
1061     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1062     controllers
1063 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1064 iliev 1130 - Implemented new, improved notification system
1065 schoenebeck 1149 - fixed compilation errors regarding OSX
1066     (patch by Toshi Nagata)
1067 iliev 1161 - implemented instruments database
1068 iliev 1345 - added support for escape sequences to the instruments database
1069 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1070     within the sampler's process (by using instrument editor plugins),
1071     you'll notice the new "Registered instrument editors:" message on
1072 schoenebeck 1407 startup, added a new LSCP command:
1073     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1074 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1075     given sampler channel, the plugin path can be overridden at compile
1076     time with ./configure --enable-plugin-dir=/some/dir
1077 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1078     in the sampler's process to safely edit instruments while playing
1079     without a crash (hopefully) by either suspending single regions
1080     wherever possible or if unavoidable whole engine(s)
1081 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1082     policy and priority on thread level, set a minimum stack size for
1083     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1084     threads simply inherited properties of starting thread instead of
1085     setting their own policy and priority
1086 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1087     main process did not wait for the stack trace process to finish
1088     its output
1089 persson 1248 - fixed some minor memory leaks
1090 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1091     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1092 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1093     register, to avoid relocations in the text segment at runtime)
1094 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1095 schoenebeck 947
1096     * MIDI driver:
1097     - dispatch bank select (MSB and LSB) messages
1098    
1099 schoenebeck 1049 * audio driver:
1100     - the ALSA audio output driver parameters now reflect the correct
1101     parameter value ranges for the respective selected sound card
1102     (patch by Till Wimmer, a bit fixed and extended)
1103    
1104 persson 951 * Gigasampler format engine:
1105     - if a filter is used and EG2 finishes before EG1, let the voice
1106     die when EG2 has finished (this fixes a problem with clicks and
1107     voice starvation for some gigs)
1108 persson 1038 - playback is no longer disabled during instrument loading
1109     - all notes playing on a channel that changes its instrument keep
1110     playing with the old instrument until they get a note off
1111     command
1112 persson 1039 - EG fix: a release value of zero could cause noises or crash
1113 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1114 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1115     above max sustain level, which means that there is a decay phase
1116     even if sustain is 100%
1117 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1118     noises or crashes
1119 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1120 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1121     supplied to the configure script (fixes #46)
1122 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1123     instead of a fix value
1124 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1125     127 (solo mode) only kill voices if the respective mode really
1126     changed
1127 persson 951
1128 schoenebeck 1244 * LSCP server:
1129     - fixed compile time error for old Bison versions
1130     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1131 schoenebeck 1245 - parser now supports extended ASCII character set
1132     (up to ASCII code 255, i.e. includes now umlauts and accents)
1133     - filename arguments in LSCP commands now allow to use escape
1134     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1135     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1136     code value like \xf2) (fixes bug #24)
1137 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1138     least one of their text-based parameters (i.e. name, description):
1139     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1140     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1141     "SET DB_INSTRUMENT_DIRECTORY NAME",
1142     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1143     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1144     "FIND DB_INSTRUMENT_DIRECTORIES"
1145 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1146     occured, the unexpected character and the actually expected, possible
1147     character(s), the latter only if less than 5 possibilities)
1148 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1149     settings
1150 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1151     of strings were treated as being one string containing commas
1152     (fixes #57)
1153 schoenebeck 1244
1154 iliev 959 * Bug fixes:
1155     - fixed crash occurring on certain LSCP scripts (Bug 39)
1156 persson 1038 - another thread safety fix for lscp "load engine" and "set
1157     channel audio output device"
1158 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1159     on a sampler channel with connected MIDI device
1160 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1161     device connected to a sampler channel to number less then or equal
1162     to the index of the port to which the sampler channel is connected.
1163 iliev 1296 - The previous bindings were not been disconnected when altering
1164     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1165     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1166 iliev 1297 - The active stream/voice count statistic was incorrect.
1167 iliev 1298 - notification events were not been sent for some sampler
1168     channel changes
1169 iliev 1305 - added default min and max values to restrict the number of allowed
1170     audio output channels and MIDI input ports
1171 iliev 1306 - the connection to the PCM interface is now closed when destroying
1172     an audio output device
1173 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1174 iliev 959
1175 schoenebeck 1221 * test cases:
1176     - updated and fixed (haven't been touched in a while)
1177    
1178 schoenebeck 937 Version 0.4.0 (24 November 2006)
1179 persson 696
1180 schoenebeck 697 * packaging changes:
1181 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1182     to post-(un)install steps; added devel package for liblinuxsampler;
1183     to linuxsampler.spec (RPM)
1184 schoenebeck 697 - install necessary development header files for allowing 3rd party
1185     applications to link against liblinuxsampler
1186     - liblinuxsampler's API documentation can be generated with 'make docs'
1187     (Doxygen required)
1188 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1189     implementation (currently either an integer math solution or a
1190     di-harmonic approximation), automatic detection can be overriden
1191     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1192     configure script argument though (mandatory for cross-compilation)
1193 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1194     provided some on his own (as CXXFLAGS)
1195 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1196     messages
1197 schoenebeck 852 - added compile time options to allow disabling the various audio and
1198     MIDI drivers
1199 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1200     (patch by Ebrahim Mayat)
1201 schoenebeck 697
1202 persson 696 * Gigasampler format engine:
1203 schoenebeck 738 - extensive synthesis optimization
1204     (reimplementation of EGs and LFO(s), removed synthesis parameter
1205     prerendering and the synthesis parameter matrix in general, splitting
1206     each audio fragment into subfragments now where each subfragment uses
1207 persson 830 constant pitch and filter coefficients. The volume coefficient is
1208     linearly interpolated inside a subfragment, unless
1209     --disable-interpolate-volume is set.)
1210 persson 696 - fine tuning of the EG modulation parameters
1211 persson 729 - improved filter cutoff calculation by adding support for the
1212     following gig parameters: Cutoff freq (used when no cutoff
1213     controller is defined), Control invert, Minimum cutoff, Velocity
1214 persson 791 curve and Velocity range. The keyboard tracking now scales
1215     cutoff frequency instead of resonance.
1216 persson 877 - added support for gig parameter Resonance.
1217 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1218 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1219     which can be overridden with --enable-global-attenuation
1220 persson 783 - EG fixes: made the length of "attack hold" stage more
1221     accurate. Release stage can now start before attack stage
1222 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1223     time now has a minimal value to prevent clicks.
1224 persson 799 - fixed pitch changes larger than one octave
1225 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1226     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1227     all modes can be altered via standard GM messages, that is CC5 for
1228     altering portamento time, CC65 for enabling / disabling portamento
1229     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1230 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1231     parameter) and crossfade
1232 persson 831 - added support for the "attenuation controller threshold" gig
1233     parameter
1234 persson 832 - added smoothing of volume changes caused by control change
1235     messages
1236 persson 865 - sample loop parameters are now taken from the DimensionRegion
1237     instead of the wave chunk
1238     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1239     not equal to a power of two
1240 persson 877 - reimplementation of the filter algorithm. The new filter is more
1241     accurate and supports all gig filter types, including bandreject
1242     and lowpass turbo.
1243 persson 903 - real support for 24 bit samples - samples are not truncated to
1244     16 bits anymore
1245     - support for aftertouch (channel pressure, not polyphonic
1246     aftertouch)
1247 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1248     amplifying from 0)
1249 persson 696
1250 schoenebeck 711 * LSCP server:
1251     - fixed application exit on broken pipe error (fixes bug #20)
1252 iliev 793 - fixed the notification messages delay due to lack of
1253     network activity (fixes bug #26)
1254 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1255     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1256 schoenebeck 711
1257 schoenebeck 838 * audio driver:
1258     - added aRts audio output driver (by no means RT safe)
1259    
1260 schoenebeck 775 * MIDI driver:
1261     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1262     messages several times instead of once
1263 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1264     for events (i.e. for offline rendering based MIDI drivers)
1265 persson 922 - added checks for bad MIDI data
1266 schoenebeck 775
1267 schoenebeck 900 * linuxsampler application:
1268     - show available sampler engine types on startup
1269    
1270 schoenebeck 705 * general changes:
1271     - support for muting sampler channels and solo mode of the same, two new
1272     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1273     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1274     introduced for this, the behavior is the same like on a mixer console
1275 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1276     --enable-process-muted-channels which can be used to enable the
1277     processing of muted channels.
1278 iliev 777 - support for sostenuto pedal
1279 iliev 779 - support for monitoring the total number of active voices
1280 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1281     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1282 persson 835 - fixed some memory management errors
1283 persson 841 - fixed some concurrency problems that could lead to crashes when
1284     LSCP commands were executed
1285 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1286     sampler channel (fixes bug #36)
1287 schoenebeck 705
1288 schoenebeck 692 Version 0.3.3 (15 July 2005)
1289 schoenebeck 686
1290     * packaging changes:
1291     - fixed compilation with gcc 4.0
1292    
1293 schoenebeck 687 * Gigasampler format engine:
1294     - LFO preprocessing was performed even though the respective LFO was
1295     disabled by the instrument patch (minor efficiency fix)
1296 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1297     for volume ramp downs in the same fragment (needed for current voice
1298     stealing implementation) then simply inform the user with a warning
1299     about possible click sounds and reduce the volume ramp down
1300     appropriately instead of cancelling the audio device connection
1301 schoenebeck 687
1302 schoenebeck 677 Version 0.3.2 (24 June 2005)
1303 schoenebeck 609
1304     * packaging changes:
1305     - updated autotools build files to compile on OS X
1306     (conditional compilation of CoreMIDI and MidiShare drivers)
1307 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1308     './configure --disable-asm' (definitely not recommended)
1309 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1310     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1311     (due to 'dist-bzip2' automake option)
1312 schoenebeck 649
1313     * Gigasampler format engine:
1314     - support for the gig parameters for "release velocity response" curves
1315     - fine tuning of the EGADSR envelope
1316     - volume of release triggered samples now depends on note-on velocity,
1317     note length and gig parameter "release trigger decay" instead of
1318     note-off velocity.
1319 schoenebeck 663 - revised voice stealing
1320     (fixes crash and endless loop caused by voice stealing)
1321 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1322 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1323     instead of when the respective voice is actually launched
1324     (fixes undefined behavior if stolen voices belonged to a key group -
1325     this case was followed by a "killed voice survived" error message)
1326 schoenebeck 669 - fixed minor issue with null/silence samples
1327     (those stole voices even though they don't need a voice at all which
1328     resulted in "voice stealing didn't work out" messages)
1329 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1330     instrument or audio output device change
1331 schoenebeck 654
1332 schoenebeck 620 * LSCP server:
1333 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1334 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1335 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1336 schoenebeck 609
1337 schoenebeck 668 * linuxsampler application:
1338     - added command line parameters --lscp-addr and --lscp-port to override
1339     default IP address and port of LSCP server
1340    
1341 schoenebeck 579 Version 0.3.1 (24 May 2005)
1342    
1343     * initial release
