* Fixed invalid (note-on) event ID being assigned to new Note
  objects.
* Fixed a bunch of scheduler time related bugs.
* Bumped version (2.0.0.svn47).

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".

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".
119     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
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 2871
166 schoenebeck 3050 * Instruments DB:
167     - Fixed memory access bug of general DB access code which lead to
168     undefined behavior.
169 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
170     - The instrument DB path of linuxsampler's --create-instruments-db argument
171     is now optional, if it is missing, then a default location is used.
172 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
173     - Added support for scanning Sound Font (.sf2) files.

215 persson 2382
216 persson 2086 * general changes:
217 iliev 2012 - Refactoring: moved the independent code from
218     the Gigasampler format engine to base classes
219 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
220     respective profiling code is currently broken
221 schoenebeck 2053 - Introduced support for optional environment variable
222     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
223     where the sampler shall look for instrument editor plugins
224     (patch by Luis Garrido, slightly modified).
225 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
226     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
227     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
228     note (in this implementation of the sampler its simply hard routed to
229     the 1st effect send of the sampler channel, no matter what the actual
230     effect type is)
231     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
232     note (in this implementation of the sampler its simply hard routed to
233     the 2nd effect send of the sampler channel, no matter what the actual
234     effect type is)
235 schoenebeck 2124 - implemented support for internal LADSPA effects
236 schoenebeck 2140 - raised limit of program change queue from 100 to 512
237     (as suggested by Alex Stone)

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

328     - added more v1 aliases to parser
329 persson 2091 - reduced memory usage for sfz data

710     (fixes #208)
711 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
712     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
713     practically irrelevant, however it caused problems with the new LSCP
714     shell's auto completion feature).
715 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
716     after each other (fixes #231).

719 schoenebeck 1599
720 schoenebeck 1639 * packaging changes:
721     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

742     load as we used a non-portable Linux specific struct field
743     (fixes bug #70, patch by Ronald Baljeu)
744 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
745     plugin DLL on Windows systems failed

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

765 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
766 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
767     be switched on by command line option "--stacktrace" (the automatic
768     stacktrace mechanism seems to be broken on most systems at the moment)
769 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
770     a pointer to the launched InstrumentEditor object
771 schoenebeck 1876 - added optional 3rd party user data parameter for following
772     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
773     InstrumentEditor::Launch(),

775 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
776     model more strictly
777 persson 1895 - fixes for using large audio device buffers
778 persson 1951 - Windows: add the installation directory to the DLL search path

786 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
787     opposed to the LSCP specs
788 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
789     reflected the wrong value
790 persson 1644 - fixed a memory management bug in ASIO driver
791 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
792 persson 1777 - JACK: use jack_client_open instead of the deprecated
793 persson 1748 jack_client_new
794 iliev 1829 - added (experimental) CoreAudio driver
795 persson 1888 - applied old fixes to the ASIO driver that were included in the
796     previous binary release but accidentally never committed to CVS
797     (fixes #117)
798 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
799     win64)
800 persson 1895 - VST: added support for sample rate and buffer size changes
801     - VST: close editor (Fantasia) when the VST is removed

806     stereo
807 persson 1922 - added channel routing, fxsends and midi maps to the settings
808     stored in the plugin state
809 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
810     AudioChannel::CopyTo() methods using GCC vector exensions
811     (if available)
812 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
813     exception when getting parameters from a disconnected device
814 schoenebeck 1599
815 persson 1651 * MIDI driver:
816     - added JACK MIDI driver
817 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
818     want to (mis)use it for some purpose ("fixed" in all current MIDI
819     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
820 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
821 persson 1887 CoreMidi or AU
822 persson 1889 - fixed mingw-w64 compilation error in MME driver
823 persson 1924 - made program change handling in MIDI thread real-time safe by
824     moving the logic to a non-RT thread
825 persson 1951 - fixed minor memory leak in ALSA driver
826 persson 1651
827 schoenebeck 1604 * instruments database:
828 iliev 1603 - avoid time consuming samples scanning when adding instruments
829     to the instruments database
830 iliev 1727 - added support for handling lost files in the instruments database
831 iliev 1781 - Implemented option for adding instruments in separate directories
832     in the instruments database
833     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
834 persson 1908 - work-around for missing fnmatch function on Windows to make
835     instrument database compilable
836 schoenebeck 1930 - added instrument database support on Windows
837     works with both standalone mode and VST plugin.
838     the instruments DB file is located in
839     %USERPROFILE%\.linuxsampler\instruments.db which allows different
840     databases for each windows user
841     if no DB is present it automatically creates the .linuxsampler subdir
842     and then creates an empty DB
843 persson 1943 - fixed recursive import, which was broken on Windows
844 iliev 1603
845 persson 1644 * Gigasampler format engine:
846     - fixed a memory leak that could happen when a channel was deleted
847     while notes were playing
848 persson 1646 - made it possible to load an instrument even if the audio thread
849     isn't running
850 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
851     enough for piano gigs with pedal noise samples
852 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
853     respective FX send MIDI controller was used
854 schoenebeck 1724 - added support for GM global device volume SysEx message
855 schoenebeck 1762 (can be selected at compile time to either apply globally to the
856     whole sampler [default] or only to the sampler channels that are
857     connected to the respective MIDI input port the SysEx message arrived
858     on)
859 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
860     sometimes wrongly killed in the same buffer, causing no sound to
861     be played
862 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
863     which is usally used to switch a part between chromatic sounds and
864     drumkit sounds (as opposed to their common default setting of MIDI
865     part 10 being a drumkit part and all other ones chromatic parts), in
866     LS however one can switch between the first 16 MIDI instrument maps
867     defined for the sampler
868 persson 1764 - made it possible to create multiple sample channels even if the
869     audio thread isn't running
870 persson 1844 - fixed crash when removing channel with active voices (#116)
871 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
872     un-cache the respective sample if it's really not used by any
873     sampler engine anymore
874     - re-cache samples in case they were changed by an instrument editor,
875     e.g. when a sample was added while playing (#82)
876 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
877     same time stamp as the voice's note-on event and occured both in the
878     same audio fragment cycle (fixes bug #112)
879 persson 1858 - added support for the "fine tune" and "pitch bend range"
880     instrument-level gig parameters
881     - fixed minor artifacts in pitch bend handling
882 schoenebeck 1860 - added support for GS Reset SysEx message
883 persson 1862 - allow gig files to use unlimited downward pitch shifting
884     - added a limit check for upward pitch shifting
885 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
886     note was silent
887 persson 1923 - fixed crash happening when a pitch bend event arrived at the
888     same time a new instrument was loading
889 persson 1644
890 schoenebeck 1687 * LSCP server:
891     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
892     react on MIDI data arriving on certain sampler channels (so far only
893     Note-On and Note-Off events are sent via this LSCP event)
894 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
895     react on MIDI data arriving on certain MIDI input devices (so far only
896     Note-On and Note-Off events are sent via this LSCP event)
897 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
898     SET DB_INSTRUMENT FILE_PATH
899 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
900     frontends to send MIDI messages to specific sampler channel
901     - added two additional fields to GET FILE INSTRUMENT INFO command -
902     KEY_BINDINGS and KEYSWITCH_BINDINGS
903 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
904     was incorrect
905 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
906 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
907     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
908     be triggered respectively
909     - added new LSCP command "SET STREAMS" to globally alter the maximum
910     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
911     which will be triggered respectively
912 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
913     a gigedit file dialog is opened)
914 iliev 1848 - close all connections when LSCPServer is deleted
915 iliev 1882 - hard close of all sockets on exit
916 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
917     driver
918 schoenebeck 1687
919 iliev 1761 * Bug fixes:
920     - fixed a crash which occurs when removing a sampler channel waiting
921     to start instrument loading after another channel
922 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
923     instrument loading in progress (bug #113)
924 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
925     instrument with PERSISTENT load mode
926 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
927     - fixed memory leaks when issuing the following LSCP commands:
928     GET AUDIO_OUTPUT_DRIVER INFO
929     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
930     GET MIDI_INPUT_DRIVER INFO
931     GET MIDI_INPUT_DRIVER_PARAMETER INFO
932     - fixed possible compilation error when sqlite is not present
933 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
934 iliev 1847 - fixed crash when changing the audio output device of a sampler
935     channel with loaded instrument and start playing notes
936 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
937 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
938     PowerPC, which probably could cause crashes on that platform
939 persson 1889 - fixed a memory management error which could cause a crash when a
940     plugin was unloaded
941 persson 1896 - bugfix: two private structs had the same name, which could cause
942     problems if the linker chose the wrong constructor
943 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
944     Windows
945 iliev 1761
946    
947 schoenebeck 1560 Version 0.5.1 (6 December 2007)
948 schoenebeck 1454
949     * packaging changes:
950     - added autoconf checks for pthread library
951     - added autoconf check for pthread bug found on certain NPTL-enabled
952     glibc versions (see Gentoo bug report #194076)
953 senoner 1502 - added autoconf checks for MS Windows
954 schoenebeck 1454
955 persson 1455 * general changes:
956     - bugfix: the thread used by an editor plugin didn't die when the
957     editor closed
958 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
959     out all the space. operator--() did not apply size_mask after
960     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
961     order to avoid problems with the _NonVolatileReader functions.
962     - bugfix: Stream.h: added a missing divide by BytesPerSample in
963     GetWriteSpace(). Since this function is currently only used in
964     the stream's qsort() compare function, it didn't trigger any
965     bugs.
966     - Resampler.h, Synthesizer.h: cubic interpolation now works in
967     24bit mode too. Faster method to read 24bit words on little
968     endian machines (x86): replaced 3 byte reads + shifts with a 1
969     unaligned 32bit read and shift
970     - experimental support for MS Windows (MIDI input via MME, AUDIO
971     output via ASIO)
972     - made handling of SIGINT signal (Ctrl-C) a bit more robust
973 iliev 1541 - support for monitoring the total number of active disk streams
974     (new LSCP commands: GET TOTAL_STREAM_COUNT,
975     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
976 persson 1455
977 senoner 1500 * AUDIO driver:
978 persson 1534 - added Windows ASIO low latency audio driver
979 senoner 1500
980 senoner 1485 * MIDI driver:
981 schoenebeck 1495 - added MME Windows MIDI driver
982 senoner 1485
983 schoenebeck 1471 * LSCP server:
984     - added support for Windows style path / filenames, however with
985     forward slash path separators instead of backslash
986     (i.e. "C:/foo/bar.gig")
987 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
988     apostrophes as well
989 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
990     "LIST FILE INSTRUMENTS <file>" and
991     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
992     about an arbitrary instrument file on the system where the sampler is
993     running on
994 schoenebeck 1471
995 schoenebeck 1424 Version 0.5.0 (15 October 2007)
996 schoenebeck 947
997 schoenebeck 1065 * packaging changes:
998 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
999     API header files anymore
1000 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1001     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1002 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1003     capable to execute our autoconf environment, thus no need anymore
1004     to maintain the compile time configuration file (osx/version.h) for
1005     OSX manually (patch by Toshi Nagata)
1006 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1007     parameters
1008 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1009     C++ API header files, all implementation internal global definitions
1010     are now in global_private.h
1011     - atomic.h is not exposed to the C++ API anymore
1012     - no need to include config.h anymore for using LS's API header files
1013     - fixed warnings in API doc generation
1014 schoenebeck 1065
1015 schoenebeck 947 * general changes:
1016     - replaced the old, confusing MIDI program change mechanism by a
1017     flexible MIDI instrument mapper which allows to map arbitrary
1018 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1019 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1020     loaded on the respective channel when such MIDI program change
1021     messages arrive, beside that, each entry allows to define a life-time
1022     strategy for the instrument, so the user can define whether the
1023     instrument should i.e. be permanently loaded (to be able to switch
1024     quickly among sounds) or i.e. loaded just on demand when the
1025     respective program change arrives (to safe RAM space), as well as a
1026     global volume factor for each entry, so the user can adjust the volume
1027     dynamic of his mapped instrument collection without having to modify
1028 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1029     MIDI instrument maps and assign each sampler channel individually
1030     a certain map, so that i.e. separation of normal instruments and
1031     drumkits is possible
1032 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1033     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1034 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1035     due to a constant size RingBuffer FIFO which is now replaced by a
1036     dynamic (unlimited) size std::list FIFO
1037 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1038     output channels for being processed by external effect processors
1039     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1040     controllers
1041 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1042 iliev 1130 - Implemented new, improved notification system
1043 schoenebeck 1149 - fixed compilation errors regarding OSX
1044     (patch by Toshi Nagata)
1045 iliev 1161 - implemented instruments database
1046 iliev 1345 - added support for escape sequences to the instruments database
1047 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1048     within the sampler's process (by using instrument editor plugins),
1049     you'll notice the new "Registered instrument editors:" message on
1050 schoenebeck 1407 startup, added a new LSCP command:
1051     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1052 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1053     given sampler channel, the plugin path can be overridden at compile
1054     time with ./configure --enable-plugin-dir=/some/dir
1055 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1056     in the sampler's process to safely edit instruments while playing
1057     without a crash (hopefully) by either suspending single regions
1058     wherever possible or if unavoidable whole engine(s)
1059 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1060     policy and priority on thread level, set a minimum stack size for
1061     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1062     threads simply inherited properties of starting thread instead of
1063     setting their own policy and priority
1064 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1065     main process did not wait for the stack trace process to finish
1066     its output
1067 persson 1248 - fixed some minor memory leaks
1068 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1069     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1070 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1071     register, to avoid relocations in the text segment at runtime)
1072 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1073 schoenebeck 947
1074     * MIDI driver:
1075     - dispatch bank select (MSB and LSB) messages
1076    
1077 schoenebeck 1049 * audio driver:
1078     - the ALSA audio output driver parameters now reflect the correct
1079     parameter value ranges for the respective selected sound card
1080     (patch by Till Wimmer, a bit fixed and extended)
1081    
1082 persson 951 * Gigasampler format engine:
1083     - if a filter is used and EG2 finishes before EG1, let the voice
1084     die when EG2 has finished (this fixes a problem with clicks and
1085     voice starvation for some gigs)
1086 persson 1038 - playback is no longer disabled during instrument loading
1087     - all notes playing on a channel that changes its instrument keep
1088     playing with the old instrument until they get a note off
1089     command
1090 persson 1039 - EG fix: a release value of zero could cause noises or crash
1091 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1092 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1093     above max sustain level, which means that there is a decay phase
1094     even if sustain is 100%
1095 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1096     noises or crashes
1097 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1098 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1099     supplied to the configure script (fixes #46)
1100 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1101     instead of a fix value
1102 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1103     127 (solo mode) only kill voices if the respective mode really
1104     changed
1105 persson 951
1106 schoenebeck 1244 * LSCP server:
1107     - fixed compile time error for old Bison versions
1108     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1109 schoenebeck 1245 - parser now supports extended ASCII character set
1110     (up to ASCII code 255, i.e. includes now umlauts and accents)
1111     - filename arguments in LSCP commands now allow to use escape
1112     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1113     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1114     code value like \xf2) (fixes bug #24)
1115 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1116     least one of their text-based parameters (i.e. name, description):
1117     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1118     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1119     "SET DB_INSTRUMENT_DIRECTORY NAME",
1120     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1121     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1122     "FIND DB_INSTRUMENT_DIRECTORIES"
1123 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1124     occured, the unexpected character and the actually expected, possible
1125     character(s), the latter only if less than 5 possibilities)
1126 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1127     settings
1128 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1129     of strings were treated as being one string containing commas
1130     (fixes #57)
1131 schoenebeck 1244
1132 iliev 959 * Bug fixes:
1133     - fixed crash occurring on certain LSCP scripts (Bug 39)
1134 persson 1038 - another thread safety fix for lscp "load engine" and "set
1135     channel audio output device"
1136 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1137     on a sampler channel with connected MIDI device
1138 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1139     device connected to a sampler channel to number less then or equal
1140     to the index of the port to which the sampler channel is connected.
1141 iliev 1296 - The previous bindings were not been disconnected when altering
1142     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1143     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1144 iliev 1297 - The active stream/voice count statistic was incorrect.
1145 iliev 1298 - notification events were not been sent for some sampler
1146     channel changes
1147 iliev 1305 - added default min and max values to restrict the number of allowed
1148     audio output channels and MIDI input ports
1149 iliev 1306 - the connection to the PCM interface is now closed when destroying
1150     an audio output device
1151 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1152 iliev 959
1153 schoenebeck 1221 * test cases:
1154     - updated and fixed (haven't been touched in a while)
1155    
1156 schoenebeck 937 Version 0.4.0 (24 November 2006)
1157 persson 696
1158 schoenebeck 697 * packaging changes:
1159 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1160     to post-(un)install steps; added devel package for liblinuxsampler;
1161     to linuxsampler.spec (RPM)
1162 schoenebeck 697 - install necessary development header files for allowing 3rd party
1163     applications to link against liblinuxsampler
1164     - liblinuxsampler's API documentation can be generated with 'make docs'
1165     (Doxygen required)
1166 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1167     implementation (currently either an integer math solution or a
1168     di-harmonic approximation), automatic detection can be overriden
1169     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1170     configure script argument though (mandatory for cross-compilation)
1171 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1172     provided some on his own (as CXXFLAGS)
1173 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1174     messages
1175 schoenebeck 852 - added compile time options to allow disabling the various audio and
1176     MIDI drivers
1177 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1178     (patch by Ebrahim Mayat)
1179 schoenebeck 697
1180 persson 696 * Gigasampler format engine:
1181 schoenebeck 738 - extensive synthesis optimization
1182     (reimplementation of EGs and LFO(s), removed synthesis parameter
1183     prerendering and the synthesis parameter matrix in general, splitting
1184     each audio fragment into subfragments now where each subfragment uses
1185 persson 830 constant pitch and filter coefficients. The volume coefficient is
1186     linearly interpolated inside a subfragment, unless
1187     --disable-interpolate-volume is set.)
1188 persson 696 - fine tuning of the EG modulation parameters
1189 persson 729 - improved filter cutoff calculation by adding support for the
1190     following gig parameters: Cutoff freq (used when no cutoff
1191     controller is defined), Control invert, Minimum cutoff, Velocity
1192 persson 791 curve and Velocity range. The keyboard tracking now scales
1193     cutoff frequency instead of resonance.
1194 persson 877 - added support for gig parameter Resonance.
1195 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1196 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1197     which can be overridden with --enable-global-attenuation
1198 persson 783 - EG fixes: made the length of "attack hold" stage more
1199     accurate. Release stage can now start before attack stage
1200 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1201     time now has a minimal value to prevent clicks.
1202 persson 799 - fixed pitch changes larger than one octave
1203 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1204     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1205     all modes can be altered via standard GM messages, that is CC5 for
1206     altering portamento time, CC65 for enabling / disabling portamento
1207     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1208 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1209     parameter) and crossfade
1210 persson 831 - added support for the "attenuation controller threshold" gig
1211     parameter
1212 persson 832 - added smoothing of volume changes caused by control change
1213     messages
1214 persson 865 - sample loop parameters are now taken from the DimensionRegion
1215     instead of the wave chunk
1216     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1217     not equal to a power of two
1218 persson 877 - reimplementation of the filter algorithm. The new filter is more
1219     accurate and supports all gig filter types, including bandreject
1220     and lowpass turbo.
1221 persson 903 - real support for 24 bit samples - samples are not truncated to
1222     16 bits anymore
1223     - support for aftertouch (channel pressure, not polyphonic
1224     aftertouch)
1225 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1226     amplifying from 0)
1227 persson 696
1228 schoenebeck 711 * LSCP server:
1229     - fixed application exit on broken pipe error (fixes bug #20)
1230 iliev 793 - fixed the notification messages delay due to lack of
1231     network activity (fixes bug #26)
1232 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1233     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1234 schoenebeck 711
1235 schoenebeck 838 * audio driver:
1236     - added aRts audio output driver (by no means RT safe)
1237    
1238 schoenebeck 775 * MIDI driver:
1239     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1240     messages several times instead of once
1241 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1242     for events (i.e. for offline rendering based MIDI drivers)
1243 persson 922 - added checks for bad MIDI data
1244 schoenebeck 775
1245 schoenebeck 900 * linuxsampler application:
1246     - show available sampler engine types on startup
1247    
1248 schoenebeck 705 * general changes:
1249     - support for muting sampler channels and solo mode of the same, two new
1250     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1251     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1252     introduced for this, the behavior is the same like on a mixer console
1253 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1254     --enable-process-muted-channels which can be used to enable the
1255     processing of muted channels.
1256 iliev 777 - support for sostenuto pedal
1257 iliev 779 - support for monitoring the total number of active voices
1258 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1259     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1260 persson 835 - fixed some memory management errors
1261 persson 841 - fixed some concurrency problems that could lead to crashes when
1262     LSCP commands were executed
1263 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1264     sampler channel (fixes bug #36)
1265 schoenebeck 705
1266 schoenebeck 692 Version 0.3.3 (15 July 2005)
1267 schoenebeck 686
1268     * packaging changes:
1269     - fixed compilation with gcc 4.0
1270    
1271 schoenebeck 687 * Gigasampler format engine:
1272     - LFO preprocessing was performed even though the respective LFO was
1273     disabled by the instrument patch (minor efficiency fix)
1274 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1275     for volume ramp downs in the same fragment (needed for current voice
1276     stealing implementation) then simply inform the user with a warning
1277     about possible click sounds and reduce the volume ramp down
1278     appropriately instead of cancelling the audio device connection
1279 schoenebeck 687
1280 schoenebeck 677 Version 0.3.2 (24 June 2005)
1281 schoenebeck 609
1282     * packaging changes:
1283     - updated autotools build files to compile on OS X
1284     (conditional compilation of CoreMIDI and MidiShare drivers)
1285 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1286     './configure --disable-asm' (definitely not recommended)
1287 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1288     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1289     (due to 'dist-bzip2' automake option)
1290 schoenebeck 649
1291     * Gigasampler format engine:
1292     - support for the gig parameters for "release velocity response" curves
1293     - fine tuning of the EGADSR envelope
1294     - volume of release triggered samples now depends on note-on velocity,
1295     note length and gig parameter "release trigger decay" instead of
1296     note-off velocity.
1297 schoenebeck 663 - revised voice stealing
1298     (fixes crash and endless loop caused by voice stealing)
1299 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1300 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1301     instead of when the respective voice is actually launched
1302     (fixes undefined behavior if stolen voices belonged to a key group -
1303     this case was followed by a "killed voice survived" error message)
1304 schoenebeck 669 - fixed minor issue with null/silence samples
1305     (those stole voices even though they don't need a voice at all which
1306     resulted in "voice stealing didn't work out" messages)
1307 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1308     instrument or audio output device change
1309 schoenebeck 654
1310 schoenebeck 620 * LSCP server:
1311 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1312 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1313 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1314 schoenebeck 609
1315 schoenebeck 668 * linuxsampler application:
1316     - added command line parameters --lscp-addr and --lscp-port to override
1317     default IP address and port of LSCP server
1318    
1319 schoenebeck 579 Version 0.3.1 (24 May 2005)
1320    
1321     * initial release
