* Only play release trigger samples on sustain pedal up if this behaviour
  was explicitly requested by the instrument (otherwise only on note-off).
* Bumped version (2.1.0.svn2).

1 schoenebeck 3381 Version SVN trunk (?)
2    
3     * Real-time instrument scripts:
4     - Fixed behavior of built-in NKSP functions change_sustain(),
5     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
6     and change_cutoff_release().
7    
8 schoenebeck 3444 * general changes:
9     - Only play release trigger samples on sustain pedal up if this behaviour
10     was explicitly requested by the instrument (otherwise only on note-off).
11    
12 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
13 persson 2837
14 persson 2856 * SFZ format engine:
15     - added support for <global>, <master> and #define (patch by Alby M)
16 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
17     - Added support for sfz extension opcode 'script' which may be used to
18     load real-time instrument script file (NKSP script language).
19 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
20 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
21 persson 3291 - sfz parser: allow missing space between header and opcode
22 persson 2856
23 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
24 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
25     cutoff settings.
26 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
27     all if an up-pitch of more than 40 semi tones was requested (I don't
28     think there is any stock gig sound that requires this behavior to
29     resemble its original sound).
30 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
31     be aborted (as LinuxSampler extension to the original GigaStudio 4
32     format).
33 schoenebeck 3072
34 persson 2837 * general changes:
35     - fixed printf type errors (mostly in debug messages)
36 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
37 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
38     allowing to sort data efficiently in real-time safe manner.
39     - RTList class: added methods for moving/inserting elements to arbitrary
40     position within a list.
41     - RTList class: added method fromPtr() for creating an Iterator object from
42     a raw element pointer.
43     - Attempt to partly fix resetting engine channels vs. resetting engine, an
44     overall cleanup of the Reset*(), ConnectAudioDevice(),
45     DisconnectAudioDevice() API methods would still be desirable though,
46     because the current situation is still inconsistent and error prone.
47 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
48     being directly assigned to a keyboard key. This allows more fine graded
49     processing of voices, which is i.e. required for certain instrument
50     script features.
51 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
52     (CC #64) events.
53     - Fix: Release trigger voices can now also distinguish correctly between
54     note-off and sustain pedal up events.
55 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
56     (while slow rate of crossfade smoother is preserved) to allow quick
57     volume and pan changes by instrument scripts for instance.
58 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
59     properly and thus were ignored for certain uses.
60 schoenebeck 3018 - Added new C++ API method
61     VirtualMidiDevice::SendChannelPressureToSampler().
62 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
63     sub threads is 16-byte aligned
64 schoenebeck 3054 - fixed numerous compiler warnings
65 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
66 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
67     fixes potential undefined behavior.
68 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
69     have a valid sample mapped (fixes bug #252).
70     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
71 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
72     subsequent optional argument due to glibc's implementation oddity
73     which expects a "=" sign, but no space between them.
74 persson 2837
75 schoenebeck 2866 * packaging changes:
76     - removed unnecessary dependency to libuuid
77     (originated by libgig's usage of it)
78 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
79     auto detect whether it (sh/c)ould output its messages in color.
80 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
81     substitution variable.
82     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
83 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
84     linuxsampler with instruments DB support.
85 schoenebeck 2866
86 schoenebeck 2871 * Real-time instrument scripts:
87     - Implemented scheduler for delayed MIDI events and for suspended scripts.
88     - Built-in script function "wait()": implemented support for function's
89     "duration-us" argument, thus scripts using this function are now
90     correctly resumed after the requested amount of microseconds.
91     - Built-in script function "play_note()": implemented support for
92     function's "duration-us" argument, thus notes triggered with this
93     argument are now correctly released after the requested amount of
94     microseconds.
95     - Fix: script events were not cleared when engine channel was reset,
96     potentially causing undefined behavior.
97     - Fixed crash which happened when trying to reference an undeclared
98     variable.
99 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
100     special value -1 for "duration-us" argument, which will cause the
101     triggered note to be released once the original note was released.
102 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
103     - Added new API method ScriptVM::syntaxHighlighting() which provides
104     a convenient syntax highlighting backend for external instrument
105     script editor applications.
106 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
107     - Extended parser issues to provide not only first line and first
108     column, but also last line and last column of issue (thus marking
109     the precise span of the issue within the source code).
110 schoenebeck 2902 - Reload script automatically after being modified by an instrument
111     editor.
112 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies

120     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
121     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
122     "event_status()" function.
123     - NKSP language: Added support for bitwise operators ".or.", ".and."
124     and ".not.".
125     - NKSP language scanner: Fixed IDs matching to require at least one
126     character (i.e. when matching function names or variable names).
127     - NKSP language scanner: disabled unusued rules.
128 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
129     be distinguished engine internally from "real" MIDI note on/off
130     events in order to avoid misbehaviors like hanging notes.
131 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
132     - Implemented built-in script variable "$NKSP_REAL_TIMER".
133     - Implemented built-in script variable "$NKSP_PERF_TIMER".

137     - NKSP language fix: division expressions were evaluated too often.
138     - NKSP language fix: string concatenation operator was right
139     associative instead of left (to right).
140 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
141     (i.e. "if end if").
142 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
143     - Implemented built-in script variable "$NI_CALLBACK_ID".
144     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
145     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

154     - Implemented built-in script function "change_decay()".
155     - Implemented built-in script function "change_release()".
156 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
157     synthesis parameter changes immediately in case the respective note
158     was triggered at the same time, instead of scheduling the parameter
159     change, especially because it would cause some parameter types's
160     changes either to be ramped (i.e. change_vol()) or other types even
161     to have not effect at all (i.e. change_attack()).
162 schoenebeck 2965 - Implemented built-in script function "sh_left()".

166 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
167     was loaded.
168     - NKSP built-in wait() script function: abort script execution if
169     a negative or zero wait time was passed as argument (since this is
170     a common indication of a bug either of the script or even of the
171     engine, which could lead to RT instability or even worse).
172 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
173     threatening scripts.
174 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
175 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an

188     script functions "change_vol()", "change_tune()", "change_pan()",
189     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
190     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
191     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
192 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
193     of its possible parameter selections.
194     - Added built-in script function "set_event_par()" and implemented some
195     of its possible parameter selections.
196 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
197 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
198 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
199     built-in function "ignore_controller()".
200 schoenebeck 3214 - Implemented built-in script function "change_velo()".
201     - Implemented built-in script function "change_note()".
202 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
203     intuitive behavior if used in combination with "change_vol_time()" or
204     "change_tune_time()" respectively: now tuning/volume changes are only
205     assigned (without delay) immediately to a new note if the respective
206     timing function has not been called before, otherwise the volume/tuning
207     changes are automatically faded (before, only the event's time stamp was
208     relevant).
209 schoenebeck 3221 - Implemented built-in script function "array_equal()".
210     - Implemented built-in script function "search()".
211     - Implemented built-in script function "sort()".

214     available for gig format engine).
215 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
216     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
217     - Implemented built-in script function "change_vol_curve()".
218     - Implemented built-in script function "change_tune_curve()".
219 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
220     offset with argument 3, where special value -1 means to use the regular
221     sample offset as defined by the instrument file.
222 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
223     - Built-in variable $EVENT_NOTE is now a read-only variable.
224     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
225     - built-in "play_note()" function now accepts -2 for its fourth argument
226     (note duration) which means the life time of the note shall be sticked
227     to the requested note number of argument 1.
228     - Fix: built-in "play_note()" function now returns 0 as result value if
229     -1 was passed for its fourth argument (note duration) and the respective
230     parent note is already gone.
231 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".

240 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
241     "init" event handlers.
242 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
243     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
244     to retrieve all code blocks filtered out by the preprocessor.
245 schoenebeck 3293 - Added built-in script function "fork()".
246     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
247     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
248     - Fixed potential crash when accessing dynamic built-in array variables.

250     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
251     - Added built-in constant $CALLBACK_STATUS_QUEUE.
252     - Added built-in constant $CALLBACK_STATUS_RUNNING.
253 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",

255     for doubling the respective time.
256 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
257     to a lexer start condition stack underrun.
258     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
259     USE_CODE_IF_NOT() preprocessor statements.
260 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
261     can be set to disable all subsequent built-in "message()" function calls
262     on preprocessor level.
263 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
264 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
265     to avoid the editor app to crash on ill-formed text input.
266 schoenebeck 3335 - Added built-in script function "change_pan_time()".
267     - Added built-in script function "change_pan_curve()".

324 persson 2382
325 persson 2086 * general changes:
326 iliev 2012 - Refactoring: moved the independent code from
327     the Gigasampler format engine to base classes
328 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
329     respective profiling code is currently broken
330 schoenebeck 2053 - Introduced support for optional environment variable
331     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
332     where the sampler shall look for instrument editor plugins
333     (patch by Luis Garrido, slightly modified).
334 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
335     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
336     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
337     note (in this implementation of the sampler its simply hard routed to
338     the 1st effect send of the sampler channel, no matter what the actual
339     effect type is)
340     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
341     note (in this implementation of the sampler its simply hard routed to
342     the 2nd effect send of the sampler channel, no matter what the actual
343     effect type is)
344 schoenebeck 2124 - implemented support for internal LADSPA effects
345 schoenebeck 2140 - raised limit of program change queue from 100 to 512

351     EngineChannel::InstrumentFileName(int index)
352     allowing to retrieve the whole list of files used for the loaded
353     instrument on an engine channel (a.k.a. part). Some GigaStudio
354     instruments for example are splitted over several files like
355     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
356 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().

360 schoenebeck 2377 - Various "const" and "restrict" optimizations.
361 persson 2382 - all engines: add pan CC value to instrument pan parameter before
362     applying panning, instead of using two separate pan functions in
363     series (#182)

365     used it everywhere appropriate
366 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
367     - Exposed scale tuning to C++ API (along to the already existing standard
368     SysEx way).
369 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
370     and broken for ppc64. (Seq_cst loads and stores are actually not
371     used in LS, so the bug wasn't noticable.)
372     - lsatomic.h: added ARMv7 support
373 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
374     added various new C++ methods for this new feature / design change, old
375     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
376     as deprecated but are still there and should provide full behavior
377     backward compatibility).
378     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
379     unsafe and caused compilation error with clang 2.x).
380 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
381 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
382     sampler from the command line by providing LSCP aware features.
383 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
384     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
385     - VirtualMidiDevice: Added support for pitch bend.
386 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
387     polyphonic key pressure events (so far polyphonic pressure was not
388     supported at all, and channel pressure was rerouted as CC128 but not
389     used so far).
390 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
391     code is shared by all sampler engine implemementations, however only the
392     gig file format currently provides support for storing instrument scripts
393     (as LinuxSampler extension to the original GigaStudio 4 format).

791     after MIDI/audio device creation failure
792 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

794     took the full preloading time and on 1st program change the respective
795     instrument was completely reloaded again.
796 persson 2277 - fixed handling of rapid bank select and program change messages
797     sent to the same sampler channel (patch from the Open Octave

818 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
819     (fixes #208)
820 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
821     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
822     practically irrelevant, however it caused problems with the new LSCP
823     shell's auto completion feature).
824 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
825     after each other (fixes #231).

877     stacktrace mechanism seems to be broken on most systems at the moment)
878 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
879     a pointer to the launched InstrumentEditor object
880 schoenebeck 1876 - added optional 3rd party user data parameter for following

904 persson 1888 - applied old fixes to the ASIO driver that were included in the
905     previous binary release but accidentally never committed to CVS
906     (fixes #117)
907 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

944     instrument database compilable
945 schoenebeck 1930 - added instrument database support on Windows
946     works with both standalone mode and VST plugin.
947     the instruments DB file is located in
948     %USERPROFILE%\.linuxsampler\instruments.db which allows different

950     if no DB is present it automatically creates the .linuxsampler subdir
951     and then creates an empty DB
952 persson 1943 - fixed recursive import, which was broken on Windows
953 iliev 1603
954 persson 1644 * Gigasampler format engine:

958     isn't running
959 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
960     enough for piano gigs with pedal noise samples
961 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
962     respective FX send MIDI controller was used
963 schoenebeck 1724 - added support for GM global device volume SysEx message
964 schoenebeck 1762 (can be selected at compile time to either apply globally to the

966     connected to the respective MIDI input port the SysEx message arrived
967     on)
968 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
969     sometimes wrongly killed in the same buffer, causing no sound to
970     be played
971 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
972     which is usally used to switch a part between chromatic sounds and
973     drumkit sounds (as opposed to their common default setting of MIDI
974     part 10 being a drumkit part and all other ones chromatic parts), in
975     LS however one can switch between the first 16 MIDI instrument maps
976     defined for the sampler
977 persson 1764 - made it possible to create multiple sample channels even if the
978     audio thread isn't running

982     sampler engine anymore
983     - re-cache samples in case they were changed by an instrument editor,
984     e.g. when a sample was added while playing (#82)
985 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
986     same time stamp as the voice's note-on event and occured both in the
987     same audio fragment cycle (fixes bug #112)
988 persson 1858 - added support for the "fine tune" and "pitch bend range"
989     instrument-level gig parameters
990     - fixed minor artifacts in pitch bend handling
991 schoenebeck 1860 - added support for GS Reset SysEx message
992 persson 1862 - allow gig files to use unlimited downward pitch shifting
993     - added a limit check for upward pitch shifting
994 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
995     note was silent
996 persson 1923 - fixed crash happening when a pitch bend event arrived at the
997     same time a new instrument was loading
998 persson 1644
999 schoenebeck 1687 * LSCP server:
1000     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

1011     KEY_BINDINGS and KEYSWITCH_BINDINGS
1012 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1013     was incorrect
1014 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1015 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1016     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1017     be triggered respectively
1018     - added new LSCP command "SET STREAMS" to globally alter the maximum
1019     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1020     which will be triggered respectively

1065     - bugfix: the thread used by an editor plugin didn't die when the
1066     editor closed
1067 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1068     out all the space. operator--() did not apply size_mask after
1069     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1070     order to avoid problems with the _NonVolatileReader functions.
1071     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1072     GetWriteSpace(). Since this function is currently only used in
1073     the stream's qsort() compare function, it didn't trigger any
1074     bugs.
1075     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1076     24bit mode too. Faster method to read 24bit words on little
1077     endian machines (x86): replaced 3 byte reads + shifts with a 1
1078     unaligned 32bit read and shift
1079     - experimental support for MS Windows (MIDI input via MME, AUDIO
1080     output via ASIO)
1081     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1082 iliev 1541 - support for monitoring the total number of active disk streams
1083     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1084     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1085 persson 1455
1086 senoner 1500 * AUDIO driver:
1087 persson 1534 - added Windows ASIO low latency audio driver
1088 senoner 1500
1089 senoner 1485 * MIDI driver:
1090 schoenebeck 1495 - added MME Windows MIDI driver
1091 senoner 1485
1092 schoenebeck 1471 * LSCP server:
1093     - added support for Windows style path / filenames, however with
1094     forward slash path separators instead of backslash
1095     (i.e. "C:/foo/bar.gig")
1096 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1097     apostrophes as well
1098 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1099     "LIST FILE INSTRUMENTS <file>" and
1100     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1101     about an arbitrary instrument file on the system where the sampler is
1102     running on
1103 schoenebeck 1471
1104 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1105 schoenebeck 947
1106 schoenebeck 1065 * packaging changes:
1107 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1108     API header files anymore
1109 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1110     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1111 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1112     capable to execute our autoconf environment, thus no need anymore
1113     to maintain the compile time configuration file (osx/version.h) for
1114     OSX manually (patch by Toshi Nagata)
1115 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1116     parameters
1117 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1118     C++ API header files, all implementation internal global definitions
1119     are now in global_private.h
1120     - atomic.h is not exposed to the C++ API anymore
1121     - no need to include config.h anymore for using LS's API header files
1122     - fixed warnings in API doc generation
1123 schoenebeck 1065
1124 schoenebeck 947 * general changes:
1125     - replaced the old, confusing MIDI program change mechanism by a
1126     flexible MIDI instrument mapper which allows to map arbitrary
1127 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1128 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1129     loaded on the respective channel when such MIDI program change
1130     messages arrive, beside that, each entry allows to define a life-time
1131     strategy for the instrument, so the user can define whether the
1132     instrument should i.e. be permanently loaded (to be able to switch
1133     quickly among sounds) or i.e. loaded just on demand when the
1134     respective program change arrives (to safe RAM space), as well as a
1135     global volume factor for each entry, so the user can adjust the volume
1136     dynamic of his mapped instrument collection without having to modify
1137 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1138     MIDI instrument maps and assign each sampler channel individually
1139     a certain map, so that i.e. separation of normal instruments and
1140     drumkits is possible
1141 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1142     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1143 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1144     due to a constant size RingBuffer FIFO which is now replaced by a
1145     dynamic (unlimited) size std::list FIFO
1146 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1147     output channels for being processed by external effect processors
1148     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1149     controllers
1150 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1151 iliev 1130 - Implemented new, improved notification system
1152 schoenebeck 1149 - fixed compilation errors regarding OSX
1153     (patch by Toshi Nagata)
1154 iliev 1161 - implemented instruments database
1155 iliev 1345 - added support for escape sequences to the instruments database
1156 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1157     within the sampler's process (by using instrument editor plugins),
1158     you'll notice the new "Registered instrument editors:" message on
1159 schoenebeck 1407 startup, added a new LSCP command:
1160     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1161 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1162     given sampler channel, the plugin path can be overridden at compile
1163     time with ./configure --enable-plugin-dir=/some/dir
1164 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1165     in the sampler's process to safely edit instruments while playing
1166     without a crash (hopefully) by either suspending single regions
1167     wherever possible or if unavoidable whole engine(s)
1168 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1169     policy and priority on thread level, set a minimum stack size for
1170     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1171     threads simply inherited properties of starting thread instead of
1172     setting their own policy and priority
1173 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1174     main process did not wait for the stack trace process to finish
1175     its output
1176 persson 1248 - fixed some minor memory leaks
1177 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1178     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1179 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1180     register, to avoid relocations in the text segment at runtime)
1181 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1182 schoenebeck 947
1183     * MIDI driver:
1184     - dispatch bank select (MSB and LSB) messages
1185    
1186 schoenebeck 1049 * audio driver:
1187     - the ALSA audio output driver parameters now reflect the correct
1188     parameter value ranges for the respective selected sound card
1189     (patch by Till Wimmer, a bit fixed and extended)
1190    
1191 persson 951 * Gigasampler format engine:
1192     - if a filter is used and EG2 finishes before EG1, let the voice
1193     die when EG2 has finished (this fixes a problem with clicks and
1194     voice starvation for some gigs)
1195 persson 1038 - playback is no longer disabled during instrument loading
1196     - all notes playing on a channel that changes its instrument keep
1197     playing with the old instrument until they get a note off
1198     command
1199 persson 1039 - EG fix: a release value of zero could cause noises or crash
1200 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1201 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1202     above max sustain level, which means that there is a decay phase
1203     even if sustain is 100%
1204 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1205     noises or crashes
1206 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1207 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1208     supplied to the configure script (fixes #46)
1209 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1210     instead of a fix value
1211 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1212     127 (solo mode) only kill voices if the respective mode really
1213     changed
1214 persson 951
1215 schoenebeck 1244 * LSCP server:
1216     - fixed compile time error for old Bison versions
1217     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1218 schoenebeck 1245 - parser now supports extended ASCII character set
1219     (up to ASCII code 255, i.e. includes now umlauts and accents)
1220     - filename arguments in LSCP commands now allow to use escape
1221     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1222     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1223     code value like \xf2) (fixes bug #24)
1224 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1225     least one of their text-based parameters (i.e. name, description):
1226     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1227     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1228     "SET DB_INSTRUMENT_DIRECTORY NAME",
1229     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1230     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1231     "FIND DB_INSTRUMENT_DIRECTORIES"
1232 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1233     occured, the unexpected character and the actually expected, possible
1234     character(s), the latter only if less than 5 possibilities)
1235 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1236     settings
1237 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1238     of strings were treated as being one string containing commas
1239     (fixes #57)
1240 schoenebeck 1244
1241 iliev 959 * Bug fixes:
1242     - fixed crash occurring on certain LSCP scripts (Bug 39)
1243 persson 1038 - another thread safety fix for lscp "load engine" and "set
1244     channel audio output device"
1245 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1246     on a sampler channel with connected MIDI device
1247 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1248     device connected to a sampler channel to number less then or equal
1249     to the index of the port to which the sampler channel is connected.
1250 iliev 1296 - The previous bindings were not been disconnected when altering
1251     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1252     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1253 iliev 1297 - The active stream/voice count statistic was incorrect.
1254 iliev 1298 - notification events were not been sent for some sampler
1255     channel changes
1256 iliev 1305 - added default min and max values to restrict the number of allowed
1257     audio output channels and MIDI input ports
1258 iliev 1306 - the connection to the PCM interface is now closed when destroying
1259     an audio output device
1260 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1261 iliev 959
1262 schoenebeck 1221 * test cases:
1263     - updated and fixed (haven't been touched in a while)
1264    
1265 schoenebeck 937 Version 0.4.0 (24 November 2006)
1266 persson 696
1267 schoenebeck 697 * packaging changes:
1268 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1269     to post-(un)install steps; added devel package for liblinuxsampler;
1270     to linuxsampler.spec (RPM)
1271 schoenebeck 697 - install necessary development header files for allowing 3rd party
1272     applications to link against liblinuxsampler
1273     - liblinuxsampler's API documentation can be generated with 'make docs'
1274     (Doxygen required)
1275 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1276     implementation (currently either an integer math solution or a
1277     di-harmonic approximation), automatic detection can be overriden
1278     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1279     configure script argument though (mandatory for cross-compilation)
1280 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1281     provided some on his own (as CXXFLAGS)
1282 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1283     messages
1284 schoenebeck 852 - added compile time options to allow disabling the various audio and
1285     MIDI drivers
1286 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1287     (patch by Ebrahim Mayat)
1288 schoenebeck 697
1289 persson 696 * Gigasampler format engine:
1290 schoenebeck 738 - extensive synthesis optimization
1291     (reimplementation of EGs and LFO(s), removed synthesis parameter
1292     prerendering and the synthesis parameter matrix in general, splitting
1293     each audio fragment into subfragments now where each subfragment uses
1294 persson 830 constant pitch and filter coefficients. The volume coefficient is
1295     linearly interpolated inside a subfragment, unless
1296     --disable-interpolate-volume is set.)
1297 persson 696 - fine tuning of the EG modulation parameters
1298 persson 729 - improved filter cutoff calculation by adding support for the
1299     following gig parameters: Cutoff freq (used when no cutoff
1300     controller is defined), Control invert, Minimum cutoff, Velocity
1301 persson 791 curve and Velocity range. The keyboard tracking now scales
1302     cutoff frequency instead of resonance.
1303 persson 877 - added support for gig parameter Resonance.
1304 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1305 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1306     which can be overridden with --enable-global-attenuation
1307 persson 783 - EG fixes: made the length of "attack hold" stage more
1308     accurate. Release stage can now start before attack stage
1309 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1310     time now has a minimal value to prevent clicks.
1311 persson 799 - fixed pitch changes larger than one octave
1312 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1313     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1314     all modes can be altered via standard GM messages, that is CC5 for
1315     altering portamento time, CC65 for enabling / disabling portamento
1316     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1317 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1318     parameter) and crossfade
1319 persson 831 - added support for the "attenuation controller threshold" gig
1320     parameter
1321 persson 832 - added smoothing of volume changes caused by control change
1322     messages
1323 persson 865 - sample loop parameters are now taken from the DimensionRegion
1324     instead of the wave chunk
1325     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1326     not equal to a power of two
1327 persson 877 - reimplementation of the filter algorithm. The new filter is more
1328     accurate and supports all gig filter types, including bandreject
1329     and lowpass turbo.
1330 persson 903 - real support for 24 bit samples - samples are not truncated to
1331     16 bits anymore
1332     - support for aftertouch (channel pressure, not polyphonic
1333     aftertouch)
1334 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1335     amplifying from 0)
1336 persson 696
1337 schoenebeck 711 * LSCP server:
1338     - fixed application exit on broken pipe error (fixes bug #20)
1339 iliev 793 - fixed the notification messages delay due to lack of
1340     network activity (fixes bug #26)
1341 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1342     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1343 schoenebeck 711
1344 schoenebeck 838 * audio driver:
1345     - added aRts audio output driver (by no means RT safe)
1346    
1347 schoenebeck 775 * MIDI driver:
1348     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1349     messages several times instead of once
1350 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1351     for events (i.e. for offline rendering based MIDI drivers)
1352 persson 922 - added checks for bad MIDI data
1353 schoenebeck 775
1354 schoenebeck 900 * linuxsampler application:
1355     - show available sampler engine types on startup
1356    
1357 schoenebeck 705 * general changes:
1358     - support for muting sampler channels and solo mode of the same, two new
1359     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1360     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1361     introduced for this, the behavior is the same like on a mixer console
1362 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1363     --enable-process-muted-channels which can be used to enable the
1364     processing of muted channels.
1365 iliev 777 - support for sostenuto pedal
1366 iliev 779 - support for monitoring the total number of active voices
1367 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1368     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1369 persson 835 - fixed some memory management errors
1370 persson 841 - fixed some concurrency problems that could lead to crashes when
1371     LSCP commands were executed
1372 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1373     sampler channel (fixes bug #36)
1374 schoenebeck 705
1375 schoenebeck 692 Version 0.3.3 (15 July 2005)
1376 schoenebeck 686
1377     * packaging changes:
1378     - fixed compilation with gcc 4.0
1379    
1380 schoenebeck 687 * Gigasampler format engine:
1381     - LFO preprocessing was performed even though the respective LFO was
1382     disabled by the instrument patch (minor efficiency fix)
1383 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1384     for volume ramp downs in the same fragment (needed for current voice
1385     stealing implementation) then simply inform the user with a warning
1386     about possible click sounds and reduce the volume ramp down
1387     appropriately instead of cancelling the audio device connection
1388 schoenebeck 687
1389 schoenebeck 677 Version 0.3.2 (24 June 2005)
1390 schoenebeck 609
1391     * packaging changes:
1392     - updated autotools build files to compile on OS X
1393     (conditional compilation of CoreMIDI and MidiShare drivers)
1394 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1395     './configure --disable-asm' (definitely not recommended)
1396 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1397     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1398     (due to 'dist-bzip2' automake option)
1399 schoenebeck 649
1400     * Gigasampler format engine:
1401     - support for the gig parameters for "release velocity response" curves
1402     - fine tuning of the EGADSR envelope
1403     - volume of release triggered samples now depends on note-on velocity,
1404     note length and gig parameter "release trigger decay" instead of
1405     note-off velocity.
1406 schoenebeck 663 - revised voice stealing
1407     (fixes crash and endless loop caused by voice stealing)
1408 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1409 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1410     instead of when the respective voice is actually launched
1411     (fixes undefined behavior if stolen voices belonged to a key group -
1412     this case was followed by a "killed voice survived" error message)
1413 schoenebeck 669 - fixed minor issue with null/silence samples
1414     (those stole voices even though they don't need a voice at all which
1415     resulted in "voice stealing didn't work out" messages)
1416 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1417     instrument or audio output device change
1418 schoenebeck 654
1419 schoenebeck 620 * LSCP server:
1420 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1421 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1422 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1423 schoenebeck 609
1424 schoenebeck 668 * linuxsampler application:
1425     - added command line parameters --lscp-addr and --lscp-port to override
1426     default IP address and port of LSCP server
1427    
1428 schoenebeck 579 Version 0.3.1 (24 May 2005)
1429    
1430     * initial release
