  some of its possible parameter selections.
* NKSP: Fixed (removed) artificial value limit for duration argument of
  built-in script functions "change_vol_time()" and "change_tune_time()".
* Fixed compile error with pre-C++11 compilers.
* Bumped version (2.0.0.svn46).

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 persson 2837
47 schoenebeck 2866 * packaging changes:
48     - removed unnecessary dependency to libuuid
49     (originated by libgig's usage of it)
50 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
51     auto detect whether it (sh/c)ould output its messages in color.
52 schoenebeck 2866
53 schoenebeck 2871 * Real-time instrument scripts:
54     - Implemented scheduler for delayed MIDI events and for suspended scripts.
55     - Built-in script function "wait()": implemented support for function's
56     "duration-us" argument, thus scripts using this function are now
57     correctly resumed after the requested amount of microseconds.
58     - Built-in script function "play_note()": implemented support for
59     function's "duration-us" argument, thus notes triggered with this
60     argument are now correctly released after the requested amount of
61     microseconds.
62     - Fix: script events were not cleared when engine channel was reset,
63     potentially causing undefined behavior.
64     - Fixed crash which happened when trying to reference an undeclared
65     variable.
66 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
67     special value -1 for "duration-us" argument, which will cause the
68     triggered note to be released once the original note was released.
69 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
70     - Added new API method ScriptVM::syntaxHighlighting() which provides
71     a convenient syntax highlighting backend for external instrument
72     script editor applications.
73 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
74     - Extended parser issues to provide not only first line and first
75     column, but also last line and last column of issue (thus marking
76     the precise span of the issue within the source code).
77 schoenebeck 2902 - Reload script automatically after being modified by an instrument
78     editor.
79 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
80     like "on note end on".

86     - Implemented built-in script function "event_status()".
87     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
88     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
89     "event_status()" function.
90     - NKSP language: Added support for bitwise operators ".or.", ".and."
91     and ".not.".
92     - NKSP language scanner: Fixed IDs matching to require at least one
93     character (i.e. when matching function names or variable names).
94     - NKSP language scanner: disabled unusued rules.
95 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
96     be distinguished engine internally from "real" MIDI note on/off
97     events in order to avoid misbehaviors like hanging notes.
98 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
99     - Implemented built-in script variable "$NKSP_REAL_TIMER".
100     - Implemented built-in script variable "$NKSP_PERF_TIMER".
101     - Implemented built-in script variable "$ENGINE_UPTIME".
102 schoenebeck 2945 - Implemented built-in script function "inc()".
103     - Implemented built-in script function "dec()".
104     - NKSP language fix: division expressions were evaluated too often.
105     - NKSP language fix: string concatenation operator was right
106     associative instead of left (to right).
107 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
108     (i.e. "if end if").
109 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
110     - Implemented built-in script variable "$NI_CALLBACK_ID".
111     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
112     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
113     - Added support for read-only built-in variables (respectively
114     handled by the script parser).
115     - Added built-in script constant "$NI_CB_TYPE_INIT".
116     - Added built-in script constant "$NI_CB_TYPE_NOTE".
117     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
118     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
119 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
120 schoenebeck 2953 - Implemented built-in script function "change_attack()".
121     - Implemented built-in script function "change_decay()".
122     - Implemented built-in script function "change_release()".
123 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
124     synthesis parameter changes immediately in case the respective note
125     was triggered at the same time, instead of scheduling the parameter
126     change, especially because it would cause some parameter types's
127     changes either to be ramped (i.e. change_vol()) or other types even
128     to have not effect at all (i.e. change_attack()).
129 schoenebeck 2965 - Implemented built-in script function "sh_left()".
130     - Implemented built-in script function "sh_right()".
131 schoenebeck 2970 - Implemented built-in script function "min()".
132     - Implemented built-in script function "max()".
133 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
134     was loaded.
135     - NKSP built-in wait() script function: abort script execution if
136     a negative or zero wait time was passed as argument (since this is
137     a common indication of a bug either of the script or even of the
138     engine, which could lead to RT instability or even worse).
139 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
140     threatening scripts.
141 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
142 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
143     initializer list to an array variable.
144 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
145 schoenebeck 3076 - Implemented built-in script function "in_range()".
146 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
147     - Implemented built-in script function "change_amp_lfo_freq()".
148     - Implemented built-in script function "change_pitch_lfo_depth()".
149     - Implemented built-in script function "change_pitch_lfo_freq()".
150 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
151     - Implemented built-in script function "change_tune_time()".
152     - Implemented built-in script function "fade_in()".
153     - Implemented built-in script function "fade_out()".
154     - Fixed acceptance of wrong data type of parameters passed to built-in
155     script functions "change_vol()", "change_tune()", "change_pan()",
156     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
157     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
158     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
159 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
160     of its possible parameter selections.
161     - Added built-in script function "set_event_par()" and implemented some
162     of its possible parameter selections.
163 schoenebeck 2871
164 schoenebeck 3050 * Instruments DB:
165     - Fixed memory access bug of general DB access code which lead to
166     undefined behavior.
167 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
168     - The instrument DB path of linuxsampler's --create-instruments-db argument
169     is now optional, if it is missing, then a default location is used.

212     in order to get rid of warnings from automake 1.14
213 persson 2382
214 persson 2086 * general changes:
215 iliev 2012 - Refactoring: moved the independent code from
216     the Gigasampler format engine to base classes
217 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
218     respective profiling code is currently broken
219 schoenebeck 2053 - Introduced support for optional environment variable
220     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
221     where the sampler shall look for instrument editor plugins
222     (patch by Luis Garrido, slightly modified).
223 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
224     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
225     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
226     note (in this implementation of the sampler its simply hard routed to
227     the 1st effect send of the sampler channel, no matter what the actual
228     effect type is)
229     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
230     note (in this implementation of the sampler its simply hard routed to
231     the 2nd effect send of the sampler channel, no matter what the actual
232     effect type is)
233 schoenebeck 2124 - implemented support for internal LADSPA effects
234 schoenebeck 2140 - raised limit of program change queue from 100 to 512
235     (as suggested by Alex Stone)

237 iliev 2296 - experimental support for per voice equalization
238 iliev 2306 - added command line option --exec-after-init
239 schoenebeck 2330 - Introduced new C++ API method:
240     EngineChannel::InstrumentFileName(int index)
241     allowing to retrieve the whole list of files used for the loaded
242     instrument on an engine channel (a.k.a. part). Some GigaStudio
243     instruments for example are splitted over several files like
244     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
245 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
246     - Added new C++ API method Sampler::GetGlobalMaxStreams().
247     - Added new C++ API method Sampler::SetGlobalMaxVoices().
248     - Added new C++ API method Sampler::SetGlobalMaxStreams().
249 schoenebeck 2377 - Various "const" and "restrict" optimizations.
250 persson 2382 - all engines: add pan CC value to instrument pan parameter before
251     applying panning, instead of using two separate pan functions in
252     series (#182)
253 persson 2427 - added a lock guard class for exception safe mutex handling and
254     used it everywhere appropriate
255 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
256     - Exposed scale tuning to C++ API (along to the already existing standard
257     SysEx way).
258 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
259     and broken for ppc64. (Seq_cst loads and stores are actually not
260     used in LS, so the bug wasn't noticable.)
261     - lsatomic.h: added ARMv7 support
262 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
263     added various new C++ methods for this new feature / design change, old
264     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
265     as deprecated but are still there and should provide full behavior
266     backward compatibility).
267     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
268     unsafe and caused compilation error with clang 2.x).
269 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
270 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
271     sampler from the command line by providing LSCP aware features.
272 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
273     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
274     - VirtualMidiDevice: Added support for pitch bend.
275 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
276     polyphonic key pressure events (so far polyphonic pressure was not
277     supported at all, and channel pressure was rerouted as CC128 but not
278     used so far).
279 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
280     code is shared by all sampler engine implemementations, however only the
281     gig file format currently provides support for storing instrument scripts
282     (as LinuxSampler extension to the original GigaStudio 4 format).
283 iliev 2012
284 persson 2043 * Gigasampler format engine:
285     - implemented the "round robin keyboard" dimension
286     - fixed round robin and random dimensions for cases when number of
287     dimension zones is not a power of two
288     - made round robin use a counter for each region instead of each
289     key
290 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
291     - bugfix: filter keyboard tracking was broken
292     - filter performance fix (an unnecessary copy was made of the
293     filter parameters in each sub fragment)
294     - handle special case when pan parameter in gig file has max or
295     min value
296 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
297     doesn't sound naturally with a drumkit
298 persson 2408 - fixed EG1 modulation when attack or release is zero
299 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
300 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
301     conditions (see also previous commit on libgig).
302 persson 2673 - fixed behaviour of filter LFO
303 persson 2043
304 schoenebeck 2047 * SFZ format engine:
305 iliev 2012 - Initial implementation (not usable yet)
306 persson 2055 - added support for v2 multiple stage envelope generators
307     - added a fine-tuned v1 envelope generator instead of using the
308     one from the gig engine
309 persson 2058 - fixed memory leak and memory handling errors
310 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
311 persson 2058 - allow non-numerical key values ("C#4" for example)
312     - "key" opcode now sets pitch_keycenter too
313     - fixed error when unloading instrument with same sample used by
314     multiple regions

321 persson 2082 - added support for amp_veltrack and amp_velcurve_N
322     - fine-tuned the default velocity curve
323 persson 2086 - added support for transpose
324     - fixed crash when using sw_down/up
325     - improved logic for sw_lokey/hikey/up/down/last
326     - added more v1 aliases to parser
327 persson 2091 - reduced memory usage for sfz data
328 persson 2101 - RT-safeness: avoid malloc in audio thread
329     - fixed a bug that could cause voice stealing to fail
330 persson 2106 - optimized sample lookup
331 persson 2114 - improved support for exclusive groups (group, off_by and

337 persson 2167 - use loop markers from sample file if loop_start and loop_end are
338     not set in sfz file
339 persson 2175 - implemeted filters. Filter types: lowpass, bandpass, bandreject

341     cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
342     cutoff_cc, cutoff_chanaft.
343     - bugfix: zero ampeg_sustain didn't work

706     crashes and noise on such transitions).
707 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
708     (fixes #208)
709 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
710     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
711     practically irrelevant, however it caused problems with the new LSCP
712     shell's auto completion feature).
713 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
714     after each other (fixes #231).

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

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

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

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

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

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

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