* NKSP: Fixed polyphonic variables not being reset to zero
  after usage.
* Bumped version (2.0.0.svn48).

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 3207 - Fixed polyphonic variables not being reset to zero after usage.
166 schoenebeck 2871
167 schoenebeck 3050 * Instruments DB:
168     - Fixed memory access bug of general DB access code which lead to
169     undefined behavior.
170 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
171     - The instrument DB path of linuxsampler's --create-instruments-db argument
172     is now optional, if it is missing, then a default location is used.
173 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
174     - Added support for scanning Sound Font (.sf2) files.
175 schoenebeck 3101 - Fixed undefined DB transaction behavior.

188 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
189 persson 2197 - minor Makefile fix for building lscpparser when build and source
190     directories are separate
191 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

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

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

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

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

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

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

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

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

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

785     - removed the nonsense audio channel constraint (which was hard coded to
786     max. 100 audio channels) for most audio drivers
787 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
788     opposed to the LSCP specs
789 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
790     reflected the wrong value
791 persson 1644 - fixed a memory management bug in ASIO driver
792 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
793 persson 1777 - JACK: use jack_client_open instead of the deprecated
794 persson 1748 jack_client_new
795 iliev 1829 - added (experimental) CoreAudio driver
796 persson 1888 - applied old fixes to the ASIO driver that were included in the
797     previous binary release but accidentally never committed to CVS
798     (fixes #117)
799 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
800     win64)
801 persson 1895 - VST: added support for sample rate and buffer size changes
802     - VST: close editor (Fantasia) when the VST is removed

807     stereo
808 persson 1922 - added channel routing, fxsends and midi maps to the settings
809     stored in the plugin state
810 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
811     AudioChannel::CopyTo() methods using GCC vector exensions
812     (if available)
813 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
814     exception when getting parameters from a disconnected device
815 schoenebeck 1599
816 persson 1651 * MIDI driver:
817     - added JACK MIDI driver
818 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
819     want to (mis)use it for some purpose ("fixed" in all current MIDI
820     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
821 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
822 persson 1887 CoreMidi or AU
823 persson 1889 - fixed mingw-w64 compilation error in MME driver
824 persson 1924 - made program change handling in MIDI thread real-time safe by
825     moving the logic to a non-RT thread
826 persson 1951 - fixed minor memory leak in ALSA driver
827 persson 1651
828 schoenebeck 1604 * instruments database:
829 iliev 1603 - avoid time consuming samples scanning when adding instruments
830     to the instruments database
831 iliev 1727 - added support for handling lost files in the instruments database
832 iliev 1781 - Implemented option for adding instruments in separate directories
833     in the instruments database
834     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
835 persson 1908 - work-around for missing fnmatch function on Windows to make
836     instrument database compilable
837 schoenebeck 1930 - added instrument database support on Windows
838     works with both standalone mode and VST plugin.
839     the instruments DB file is located in
840     %USERPROFILE%\.linuxsampler\instruments.db which allows different
841     databases for each windows user
842     if no DB is present it automatically creates the .linuxsampler subdir
843     and then creates an empty DB
844 persson 1943 - fixed recursive import, which was broken on Windows
845 iliev 1603
846 persson 1644 * Gigasampler format engine:
847     - fixed a memory leak that could happen when a channel was deleted
848     while notes were playing
849 persson 1646 - made it possible to load an instrument even if the audio thread
850     isn't running
851 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
852     enough for piano gigs with pedal noise samples
853 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
854     respective FX send MIDI controller was used
855 schoenebeck 1724 - added support for GM global device volume SysEx message
856 schoenebeck 1762 (can be selected at compile time to either apply globally to the
857     whole sampler [default] or only to the sampler channels that are
858     connected to the respective MIDI input port the SysEx message arrived
859     on)
860 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
861     sometimes wrongly killed in the same buffer, causing no sound to
862     be played
863 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
864     which is usally used to switch a part between chromatic sounds and
865     drumkit sounds (as opposed to their common default setting of MIDI
866     part 10 being a drumkit part and all other ones chromatic parts), in
867     LS however one can switch between the first 16 MIDI instrument maps
868     defined for the sampler
869 persson 1764 - made it possible to create multiple sample channels even if the
870     audio thread isn't running
871 persson 1844 - fixed crash when removing channel with active voices (#116)
872 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
873     un-cache the respective sample if it's really not used by any
874     sampler engine anymore
875     - re-cache samples in case they were changed by an instrument editor,
876     e.g. when a sample was added while playing (#82)
877 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
878     same time stamp as the voice's note-on event and occured both in the
879     same audio fragment cycle (fixes bug #112)
880 persson 1858 - added support for the "fine tune" and "pitch bend range"
881     instrument-level gig parameters
882     - fixed minor artifacts in pitch bend handling
883 schoenebeck 1860 - added support for GS Reset SysEx message
884 persson 1862 - allow gig files to use unlimited downward pitch shifting
885     - added a limit check for upward pitch shifting
886 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
887     note was silent
888 persson 1923 - fixed crash happening when a pitch bend event arrived at the
889     same time a new instrument was loading
890 persson 1644
891 schoenebeck 1687 * LSCP server:
892     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
893     react on MIDI data arriving on certain sampler channels (so far only
894     Note-On and Note-Off events are sent via this LSCP event)
895 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
896     react on MIDI data arriving on certain MIDI input devices (so far only
897     Note-On and Note-Off events are sent via this LSCP event)
898 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
899     SET DB_INSTRUMENT FILE_PATH
900 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
901     frontends to send MIDI messages to specific sampler channel
902     - added two additional fields to GET FILE INSTRUMENT INFO command -
903     KEY_BINDINGS and KEYSWITCH_BINDINGS
904 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
905     was incorrect
906 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
907 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
908     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
909     be triggered respectively
910     - added new LSCP command "SET STREAMS" to globally alter the maximum
911     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
912     which will be triggered respectively
913 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
914     a gigedit file dialog is opened)
915 iliev 1848 - close all connections when LSCPServer is deleted
916 iliev 1882 - hard close of all sockets on exit
917 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
918     driver
919 schoenebeck 1687
920 iliev 1761 * Bug fixes:
921     - fixed a crash which occurs when removing a sampler channel waiting
922     to start instrument loading after another channel
923 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
924     instrument loading in progress (bug #113)
925 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
926     instrument with PERSISTENT load mode
927 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
928     - fixed memory leaks when issuing the following LSCP commands:
929     GET AUDIO_OUTPUT_DRIVER INFO
930     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
931     GET MIDI_INPUT_DRIVER INFO
932     GET MIDI_INPUT_DRIVER_PARAMETER INFO
933     - fixed possible compilation error when sqlite is not present
934 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
935 iliev 1847 - fixed crash when changing the audio output device of a sampler
936     channel with loaded instrument and start playing notes
937 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
938 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
939     PowerPC, which probably could cause crashes on that platform
940 persson 1889 - fixed a memory management error which could cause a crash when a
941     plugin was unloaded
942 persson 1896 - bugfix: two private structs had the same name, which could cause
943     problems if the linker chose the wrong constructor
944 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
945     Windows
946 iliev 1761
947    
948 schoenebeck 1560 Version 0.5.1 (6 December 2007)
949 schoenebeck 1454
950     * packaging changes:
951     - added autoconf checks for pthread library
952     - added autoconf check for pthread bug found on certain NPTL-enabled
953     glibc versions (see Gentoo bug report #194076)
954 senoner 1502 - added autoconf checks for MS Windows
955 schoenebeck 1454
956 persson 1455 * general changes:
957     - bugfix: the thread used by an editor plugin didn't die when the
958     editor closed
959 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
960     out all the space. operator--() did not apply size_mask after
961     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
962     order to avoid problems with the _NonVolatileReader functions.
963     - bugfix: Stream.h: added a missing divide by BytesPerSample in
964     GetWriteSpace(). Since this function is currently only used in
965     the stream's qsort() compare function, it didn't trigger any
966     bugs.
967     - Resampler.h, Synthesizer.h: cubic interpolation now works in
968     24bit mode too. Faster method to read 24bit words on little
969     endian machines (x86): replaced 3 byte reads + shifts with a 1
970     unaligned 32bit read and shift
971     - experimental support for MS Windows (MIDI input via MME, AUDIO
972     output via ASIO)
973     - made handling of SIGINT signal (Ctrl-C) a bit more robust
974 iliev 1541 - support for monitoring the total number of active disk streams
975     (new LSCP commands: GET TOTAL_STREAM_COUNT,
976     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
977 persson 1455
978 senoner 1500 * AUDIO driver:
979 persson 1534 - added Windows ASIO low latency audio driver
980 senoner 1500
981 senoner 1485 * MIDI driver:
982 schoenebeck 1495 - added MME Windows MIDI driver
983 senoner 1485
984 schoenebeck 1471 * LSCP server:
985     - added support for Windows style path / filenames, however with
986     forward slash path separators instead of backslash
987     (i.e. "C:/foo/bar.gig")
988 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
989     apostrophes as well
990 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
991     "LIST FILE INSTRUMENTS <file>" and
992     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
993     about an arbitrary instrument file on the system where the sampler is
994     running on
995 schoenebeck 1471
996 schoenebeck 1424 Version 0.5.0 (15 October 2007)
997 schoenebeck 947
998 schoenebeck 1065 * packaging changes:
999 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1000     API header files anymore
1001 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1002     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1003 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1004     capable to execute our autoconf environment, thus no need anymore
1005     to maintain the compile time configuration file (osx/version.h) for
1006     OSX manually (patch by Toshi Nagata)
1007 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1008     parameters
1009 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1010     C++ API header files, all implementation internal global definitions
1011     are now in global_private.h
1012     - atomic.h is not exposed to the C++ API anymore
1013     - no need to include config.h anymore for using LS's API header files
1014     - fixed warnings in API doc generation
1015 schoenebeck 1065
1016 schoenebeck 947 * general changes:
1017     - replaced the old, confusing MIDI program change mechanism by a
1018     flexible MIDI instrument mapper which allows to map arbitrary
1019 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1020 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1021     loaded on the respective channel when such MIDI program change
1022     messages arrive, beside that, each entry allows to define a life-time
1023     strategy for the instrument, so the user can define whether the
1024     instrument should i.e. be permanently loaded (to be able to switch
1025     quickly among sounds) or i.e. loaded just on demand when the
1026     respective program change arrives (to safe RAM space), as well as a
1027     global volume factor for each entry, so the user can adjust the volume
1028     dynamic of his mapped instrument collection without having to modify
1029 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1030     MIDI instrument maps and assign each sampler channel individually
1031     a certain map, so that i.e. separation of normal instruments and
1032     drumkits is possible
1033 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1034     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1035 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1036     due to a constant size RingBuffer FIFO which is now replaced by a
1037     dynamic (unlimited) size std::list FIFO
1038 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1039     output channels for being processed by external effect processors
1040     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1041     controllers
1042 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1043 iliev 1130 - Implemented new, improved notification system
1044 schoenebeck 1149 - fixed compilation errors regarding OSX
1045     (patch by Toshi Nagata)
1046 iliev 1161 - implemented instruments database
1047 iliev 1345 - added support for escape sequences to the instruments database
1048 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1049     within the sampler's process (by using instrument editor plugins),
1050     you'll notice the new "Registered instrument editors:" message on
1051 schoenebeck 1407 startup, added a new LSCP command:
1052     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1053 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1054     given sampler channel, the plugin path can be overridden at compile
1055     time with ./configure --enable-plugin-dir=/some/dir
1056 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1057     in the sampler's process to safely edit instruments while playing
1058     without a crash (hopefully) by either suspending single regions
1059     wherever possible or if unavoidable whole engine(s)
1060 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1061     policy and priority on thread level, set a minimum stack size for
1062     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1063     threads simply inherited properties of starting thread instead of
1064     setting their own policy and priority
1065 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1066     main process did not wait for the stack trace process to finish
1067     its output
1068 persson 1248 - fixed some minor memory leaks
1069 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1070     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1071 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1072     register, to avoid relocations in the text segment at runtime)
1073 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1074 schoenebeck 947
1075     * MIDI driver:
1076     - dispatch bank select (MSB and LSB) messages
1077    
1078 schoenebeck 1049 * audio driver:
1079     - the ALSA audio output driver parameters now reflect the correct
1080     parameter value ranges for the respective selected sound card
1081     (patch by Till Wimmer, a bit fixed and extended)
1082    
1083 persson 951 * Gigasampler format engine:
1084     - if a filter is used and EG2 finishes before EG1, let the voice
1085     die when EG2 has finished (this fixes a problem with clicks and
1086     voice starvation for some gigs)
1087 persson 1038 - playback is no longer disabled during instrument loading
1088     - all notes playing on a channel that changes its instrument keep
1089     playing with the old instrument until they get a note off
1090     command
1091 persson 1039 - EG fix: a release value of zero could cause noises or crash
1092 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1093 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1094     above max sustain level, which means that there is a decay phase
1095     even if sustain is 100%
1096 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1097     noises or crashes
1098 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1099 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1100     supplied to the configure script (fixes #46)
1101 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1102     instead of a fix value
1103 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1104     127 (solo mode) only kill voices if the respective mode really
1105     changed
1106 persson 951
1107 schoenebeck 1244 * LSCP server:
1108     - fixed compile time error for old Bison versions
1109     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1110 schoenebeck 1245 - parser now supports extended ASCII character set
1111     (up to ASCII code 255, i.e. includes now umlauts and accents)
1112     - filename arguments in LSCP commands now allow to use escape
1113     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1114     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1115     code value like \xf2) (fixes bug #24)
1116 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1117     least one of their text-based parameters (i.e. name, description):
1118     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1119     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1120     "SET DB_INSTRUMENT_DIRECTORY NAME",
1121     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1122     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1123     "FIND DB_INSTRUMENT_DIRECTORIES"
1124 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1125     occured, the unexpected character and the actually expected, possible
1126     character(s), the latter only if less than 5 possibilities)
1127 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1128     settings
1129 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1130     of strings were treated as being one string containing commas
1131     (fixes #57)
1132 schoenebeck 1244
1133 iliev 959 * Bug fixes:
1134     - fixed crash occurring on certain LSCP scripts (Bug 39)
1135 persson 1038 - another thread safety fix for lscp "load engine" and "set
1136     channel audio output device"
1137 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1138     on a sampler channel with connected MIDI device
1139 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1140     device connected to a sampler channel to number less then or equal
1141     to the index of the port to which the sampler channel is connected.
1142 iliev 1296 - The previous bindings were not been disconnected when altering
1143     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1144     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1145 iliev 1297 - The active stream/voice count statistic was incorrect.
1146 iliev 1298 - notification events were not been sent for some sampler
1147     channel changes
1148 iliev 1305 - added default min and max values to restrict the number of allowed
1149     audio output channels and MIDI input ports
1150 iliev 1306 - the connection to the PCM interface is now closed when destroying
1151     an audio output device
1152 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1153 iliev 959
1154 schoenebeck 1221 * test cases:
1155     - updated and fixed (haven't been touched in a while)
1156    
1157 schoenebeck 937 Version 0.4.0 (24 November 2006)
1158 persson 696
1159 schoenebeck 697 * packaging changes:
1160 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1161     to post-(un)install steps; added devel package for liblinuxsampler;
1162     to linuxsampler.spec (RPM)
1163 schoenebeck 697 - install necessary development header files for allowing 3rd party
1164     applications to link against liblinuxsampler
1165     - liblinuxsampler's API documentation can be generated with 'make docs'
1166     (Doxygen required)
1167 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1168     implementation (currently either an integer math solution or a
1169     di-harmonic approximation), automatic detection can be overriden
1170     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1171     configure script argument though (mandatory for cross-compilation)
1172 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1173     provided some on his own (as CXXFLAGS)
1174 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1175     messages
1176 schoenebeck 852 - added compile time options to allow disabling the various audio and
1177     MIDI drivers
1178 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1179     (patch by Ebrahim Mayat)
1180 schoenebeck 697
1181 persson 696 * Gigasampler format engine:
1182 schoenebeck 738 - extensive synthesis optimization
1183     (reimplementation of EGs and LFO(s), removed synthesis parameter
1184     prerendering and the synthesis parameter matrix in general, splitting
1185     each audio fragment into subfragments now where each subfragment uses
1186 persson 830 constant pitch and filter coefficients. The volume coefficient is
1187     linearly interpolated inside a subfragment, unless
1188     --disable-interpolate-volume is set.)
1189 persson 696 - fine tuning of the EG modulation parameters
1190 persson 729 - improved filter cutoff calculation by adding support for the
1191     following gig parameters: Cutoff freq (used when no cutoff
1192     controller is defined), Control invert, Minimum cutoff, Velocity
1193 persson 791 curve and Velocity range. The keyboard tracking now scales
1194     cutoff frequency instead of resonance.
1195 persson 877 - added support for gig parameter Resonance.
1196 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1197 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1198     which can be overridden with --enable-global-attenuation
1199 persson 783 - EG fixes: made the length of "attack hold" stage more
1200     accurate. Release stage can now start before attack stage
1201 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1202     time now has a minimal value to prevent clicks.
1203 persson 799 - fixed pitch changes larger than one octave
1204 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1205     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1206     all modes can be altered via standard GM messages, that is CC5 for
1207     altering portamento time, CC65 for enabling / disabling portamento
1208     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1209 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1210     parameter) and crossfade
1211 persson 831 - added support for the "attenuation controller threshold" gig
1212     parameter
1213 persson 832 - added smoothing of volume changes caused by control change
1214     messages
1215 persson 865 - sample loop parameters are now taken from the DimensionRegion
1216     instead of the wave chunk
1217     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1218     not equal to a power of two
1219 persson 877 - reimplementation of the filter algorithm. The new filter is more
1220     accurate and supports all gig filter types, including bandreject
1221     and lowpass turbo.
1222 persson 903 - real support for 24 bit samples - samples are not truncated to
1223     16 bits anymore
1224     - support for aftertouch (channel pressure, not polyphonic
1225     aftertouch)
1226 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1227     amplifying from 0)
1228 persson 696
1229 schoenebeck 711 * LSCP server:
1230     - fixed application exit on broken pipe error (fixes bug #20)
1231 iliev 793 - fixed the notification messages delay due to lack of
1232     network activity (fixes bug #26)
1233 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1234     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1235 schoenebeck 711
1236 schoenebeck 838 * audio driver:
1237     - added aRts audio output driver (by no means RT safe)
1238    
1239 schoenebeck 775 * MIDI driver:
1240     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1241     messages several times instead of once
1242 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1243     for events (i.e. for offline rendering based MIDI drivers)
1244 persson 922 - added checks for bad MIDI data
1245 schoenebeck 775
1246 schoenebeck 900 * linuxsampler application:
1247     - show available sampler engine types on startup
1248    
1249 schoenebeck 705 * general changes:
1250     - support for muting sampler channels and solo mode of the same, two new
1251     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1252     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1253     introduced for this, the behavior is the same like on a mixer console
1254 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1255     --enable-process-muted-channels which can be used to enable the
1256     processing of muted channels.
1257 iliev 777 - support for sostenuto pedal
1258 iliev 779 - support for monitoring the total number of active voices
1259 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1260     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1261 persson 835 - fixed some memory management errors
1262 persson 841 - fixed some concurrency problems that could lead to crashes when
1263     LSCP commands were executed
1264 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1265     sampler channel (fixes bug #36)
1266 schoenebeck 705
1267 schoenebeck 692 Version 0.3.3 (15 July 2005)
1268 schoenebeck 686
1269     * packaging changes:
1270     - fixed compilation with gcc 4.0
1271    
1272 schoenebeck 687 * Gigasampler format engine:
1273     - LFO preprocessing was performed even though the respective LFO was
1274     disabled by the instrument patch (minor efficiency fix)
1275 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1276     for volume ramp downs in the same fragment (needed for current voice
1277     stealing implementation) then simply inform the user with a warning
1278     about possible click sounds and reduce the volume ramp down
1279     appropriately instead of cancelling the audio device connection
1280 schoenebeck 687
1281 schoenebeck 677 Version 0.3.2 (24 June 2005)
1282 schoenebeck 609
1283     * packaging changes:
1284     - updated autotools build files to compile on OS X
1285     (conditional compilation of CoreMIDI and MidiShare drivers)
1286 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1287     './configure --disable-asm' (definitely not recommended)
1288 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1289     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1290     (due to 'dist-bzip2' automake option)
1291 schoenebeck 649
1292     * Gigasampler format engine:
1293     - support for the gig parameters for "release velocity response" curves
1294     - fine tuning of the EGADSR envelope
1295     - volume of release triggered samples now depends on note-on velocity,
1296     note length and gig parameter "release trigger decay" instead of
1297     note-off velocity.
1298 schoenebeck 663 - revised voice stealing
1299     (fixes crash and endless loop caused by voice stealing)
1300 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1301 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1302     instead of when the respective voice is actually launched
1303     (fixes undefined behavior if stolen voices belonged to a key group -
1304     this case was followed by a "killed voice survived" error message)
1305 schoenebeck 669 - fixed minor issue with null/silence samples
1306     (those stole voices even though they don't need a voice at all which
1307     resulted in "voice stealing didn't work out" messages)
1308 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1309     instrument or audio output device change
1310 schoenebeck 654
1311 schoenebeck 620 * LSCP server:
1312 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1313 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1314 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1315 schoenebeck 609
1316 schoenebeck 668 * linuxsampler application:
1317     - added command line parameters --lscp-addr and --lscp-port to override
1318     default IP address and port of LSCP server
1319    
1320 schoenebeck 579 Version 0.3.1 (24 May 2005)
1321    
1322     * initial release
