* Gig format extension: If requested by instrument then don't play
  release trigger sample on note-off events.
* Bumped version (2.1.0.svn3).

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 3448 * Gigasampler/GigaStudio format engine:
13     - Format extension: If requested by instrument then don't play release
14     trigger sample on note-off events.
15    
16 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
17 persson 2837
18 persson 2856 * SFZ format engine:
19     - added support for <global>, <master> and #define (patch by Alby M)
20 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
21     - Added support for sfz extension opcode 'script' which may be used to
22     load real-time instrument script file (NKSP script language).
23 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
24 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
25 persson 3291 - sfz parser: allow missing space between header and opcode
26 persson 2856
27 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
28 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
29     cutoff settings.
30 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
31     all if an up-pitch of more than 40 semi tones was requested (I don't
32     think there is any stock gig sound that requires this behavior to
33     resemble its original sound).
34 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
35     be aborted (as LinuxSampler extension to the original GigaStudio 4
36     format).
37 schoenebeck 3072
38 persson 2837 * general changes:
39     - fixed printf type errors (mostly in debug messages)
40 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
41 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
42     allowing to sort data efficiently in real-time safe manner.
43     - RTList class: added methods for moving/inserting elements to arbitrary
44     position within a list.
45     - RTList class: added method fromPtr() for creating an Iterator object from
46     a raw element pointer.
47     - Attempt to partly fix resetting engine channels vs. resetting engine, an
48     overall cleanup of the Reset*(), ConnectAudioDevice(),
49     DisconnectAudioDevice() API methods would still be desirable though,
50     because the current situation is still inconsistent and error prone.
51 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
52     being directly assigned to a keyboard key. This allows more fine graded
53     processing of voices, which is i.e. required for certain instrument
54     script features.
55 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
56     (CC #64) events.
57     - Fix: Release trigger voices can now also distinguish correctly between
58     note-off and sustain pedal up events.
59 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
60     (while slow rate of crossfade smoother is preserved) to allow quick
61     volume and pan changes by instrument scripts for instance.
62 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
63     properly and thus were ignored for certain uses.
64 schoenebeck 3018 - Added new C++ API method
65     VirtualMidiDevice::SendChannelPressureToSampler().
66 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
67     sub threads is 16-byte aligned
68 schoenebeck 3054 - fixed numerous compiler warnings
69 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
70 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
71     fixes potential undefined behavior.
72 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
73     have a valid sample mapped (fixes bug #252).
74     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
75 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
76     subsequent optional argument due to glibc's implementation oddity
77     which expects a "=" sign, but no space between them.
78 persson 2837
79 schoenebeck 2866 * packaging changes:
80     - removed unnecessary dependency to libuuid
81     (originated by libgig's usage of it)
82 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
83     auto detect whether it (sh/c)ould output its messages in color.
84 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
85     substitution variable.
86     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
87 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
88     linuxsampler with instruments DB support.
89 schoenebeck 2866
90 schoenebeck 2871 * Real-time instrument scripts:
91     - Implemented scheduler for delayed MIDI events and for suspended scripts.
92     - Built-in script function "wait()": implemented support for function's
93     "duration-us" argument, thus scripts using this function are now
94     correctly resumed after the requested amount of microseconds.
95     - Built-in script function "play_note()": implemented support for
96     function's "duration-us" argument, thus notes triggered with this
97     argument are now correctly released after the requested amount of
98     microseconds.
99     - Fix: script events were not cleared when engine channel was reset,
100     potentially causing undefined behavior.
101     - Fixed crash which happened when trying to reference an undeclared
102     variable.
103 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
104     special value -1 for "duration-us" argument, which will cause the
105     triggered note to be released once the original note was released.
106 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
107     - Added new API method ScriptVM::syntaxHighlighting() which provides
108     a convenient syntax highlighting backend for external instrument
109     script editor applications.
110 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
111     - Extended parser issues to provide not only first line and first
112     column, but also last line and last column of issue (thus marking
113     the precise span of the issue within the source code).
114 schoenebeck 2902 - Reload script automatically after being modified by an instrument
115     editor.
116 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies

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

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

153     - Added built-in script constant "$NI_CB_TYPE_NOTE".
154     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

158     - Implemented built-in script function "change_decay()".
159     - Implemented built-in script function "change_release()".
160 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
161     synthesis parameter changes immediately in case the respective note
162     was triggered at the same time, instead of scheduling the parameter
163     change, especially because it would cause some parameter types's
164     changes either to be ramped (i.e. change_vol()) or other types even
165     to have not effect at all (i.e. change_attack()).
166 schoenebeck 2965 - Implemented built-in script function "sh_left()".
167     - Implemented built-in script function "sh_right()".
168 schoenebeck 2970 - Implemented built-in script function "min()".

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

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

217 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
218     available for gig format engine).
219 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
220     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
221     - Implemented built-in script function "change_vol_curve()".
222     - Implemented built-in script function "change_tune_curve()".
223 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
224     offset with argument 3, where special value -1 means to use the regular
225     sample offset as defined by the instrument file.
226 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
227     - Built-in variable $EVENT_NOTE is now a read-only variable.
228     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
229     - built-in "play_note()" function now accepts -2 for its fourth argument
230     (note duration) which means the life time of the note shall be sticked
231     to the requested note number of argument 1.
232     - Fix: built-in "play_note()" function now returns 0 as result value if
233     -1 was passed for its fourth argument (note duration) and the respective
234     parent note is already gone.
235 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".

243     another script handler by passing its callback ID.
244 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
245     "init" event handlers.
246 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
247     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
248     to retrieve all code blocks filtered out by the preprocessor.
249 schoenebeck 3293 - Added built-in script function "fork()".
250     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
251     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
252     - Fixed potential crash when accessing dynamic built-in array variables.
253 schoenebeck 3296 - Added built-in script function "callback_status()".
254     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
255     - Added built-in constant $CALLBACK_STATUS_QUEUE.
256     - Added built-in constant $CALLBACK_STATUS_RUNNING.
257 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",

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

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

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

364 schoenebeck 2377 - Various "const" and "restrict" optimizations.
365 persson 2382 - all engines: add pan CC value to instrument pan parameter before
366     applying panning, instead of using two separate pan functions in
367     series (#182)
368 persson 2427 - added a lock guard class for exception safe mutex handling and
369     used it everywhere appropriate
370 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
371     - Exposed scale tuning to C++ API (along to the already existing standard
372     SysEx way).
373 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
374     and broken for ppc64. (Seq_cst loads and stores are actually not
375     used in LS, so the bug wasn't noticable.)
376     - lsatomic.h: added ARMv7 support
377 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
378     added various new C++ methods for this new feature / design change, old
379     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
380     as deprecated but are still there and should provide full behavior
381     backward compatibility).
382     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
383     unsafe and caused compilation error with clang 2.x).
384 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
385 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
386     sampler from the command line by providing LSCP aware features.
387 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
388     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
389     - VirtualMidiDevice: Added support for pitch bend.
390 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
391     polyphonic key pressure events (so far polyphonic pressure was not
392     supported at all, and channel pressure was rerouted as CC128 but not
393     used so far).
394 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
395     code is shared by all sampler engine implemementations, however only the
396     gig file format currently provides support for storing instrument scripts
397     (as LinuxSampler extension to the original GigaStudio 4 format).

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

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

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

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

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

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

957 iliev 1603
958 persson 1644 * Gigasampler format engine:

962     isn't running
963 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
964     enough for piano gigs with pedal noise samples
965 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
966     respective FX send MIDI controller was used
967 schoenebeck 1724 - added support for GM global device volume SysEx message
968 schoenebeck 1762 (can be selected at compile time to either apply globally to the
969     whole sampler [default] or only to the sampler channels that are
970     connected to the respective MIDI input port the SysEx message arrived
971     on)
972 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
973     sometimes wrongly killed in the same buffer, causing no sound to
974     be played
975 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
976     which is usally used to switch a part between chromatic sounds and
977     drumkit sounds (as opposed to their common default setting of MIDI
978     part 10 being a drumkit part and all other ones chromatic parts), in
979     LS however one can switch between the first 16 MIDI instrument maps
980     defined for the sampler
981 persson 1764 - made it possible to create multiple sample channels even if the
982     audio thread isn't running

986     sampler engine anymore
987     - re-cache samples in case they were changed by an instrument editor,
988     e.g. when a sample was added while playing (#82)
989 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
990     same time stamp as the voice's note-on event and occured both in the
991     same audio fragment cycle (fixes bug #112)
992 persson 1858 - added support for the "fine tune" and "pitch bend range"
993     instrument-level gig parameters
994     - fixed minor artifacts in pitch bend handling
995 schoenebeck 1860 - added support for GS Reset SysEx message
996 persson 1862 - allow gig files to use unlimited downward pitch shifting
997     - added a limit check for upward pitch shifting
998 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
999     note was silent
1000 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1001     same time a new instrument was loading
1002 persson 1644
1003 schoenebeck 1687 * LSCP server:
1004     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1005     react on MIDI data arriving on certain sampler channels (so far only
1006     Note-On and Note-Off events are sent via this LSCP event)
1007 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1008     react on MIDI data arriving on certain MIDI input devices (so far only
1009     Note-On and Note-Off events are sent via this LSCP event)

1014     - added two additional fields to GET FILE INSTRUMENT INFO command -
1015     KEY_BINDINGS and KEYSWITCH_BINDINGS
1016 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1017     was incorrect
1018 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1019 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1020     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1021     be triggered respectively
1022     - added new LSCP command "SET STREAMS" to globally alter the maximum
1023     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1024     which will be triggered respectively
1025 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1026     a gigedit file dialog is opened)
1027 iliev 1848 - close all connections when LSCPServer is deleted
1028 iliev 1882 - hard close of all sockets on exit

1065     glibc versions (see Gentoo bug report #194076)
1066 senoner 1502 - added autoconf checks for MS Windows
1067 schoenebeck 1454
1068 persson 1455 * general changes:
1069     - bugfix: the thread used by an editor plugin didn't die when the
1070     editor closed
1071 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1072     out all the space. operator--() did not apply size_mask after
1073     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1074     order to avoid problems with the _NonVolatileReader functions.
1075     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1076     GetWriteSpace(). Since this function is currently only used in
1077     the stream's qsort() compare function, it didn't trigger any
1078     bugs.
1079     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1080     24bit mode too. Faster method to read 24bit words on little
1081     endian machines (x86): replaced 3 byte reads + shifts with a 1
1082     unaligned 32bit read and shift
1083     - experimental support for MS Windows (MIDI input via MME, AUDIO
1084     output via ASIO)
1085     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1086 iliev 1541 - support for monitoring the total number of active disk streams
1087     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1088     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1089 persson 1455
1090 senoner 1500 * AUDIO driver:
1091 persson 1534 - added Windows ASIO low latency audio driver
1092 senoner 1500
1093 senoner 1485 * MIDI driver:
1094 schoenebeck 1495 - added MME Windows MIDI driver
1095 senoner 1485
1096 schoenebeck 1471 * LSCP server:
1097     - added support for Windows style path / filenames, however with
1098     forward slash path separators instead of backslash
1099     (i.e. "C:/foo/bar.gig")
1100 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1101     apostrophes as well
1102 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1103     "LIST FILE INSTRUMENTS <file>" and
1104     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1105     about an arbitrary instrument file on the system where the sampler is
1106     running on
1107 schoenebeck 1471
1108 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1109 schoenebeck 947
1110 schoenebeck 1065 * packaging changes:
1111 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1112     API header files anymore
1113 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1114     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1115 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1116     capable to execute our autoconf environment, thus no need anymore
1117     to maintain the compile time configuration file (osx/version.h) for
1118     OSX manually (patch by Toshi Nagata)
1119 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1120     parameters
1121 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1122     C++ API header files, all implementation internal global definitions
1123     are now in global_private.h
1124     - atomic.h is not exposed to the C++ API anymore
1125     - no need to include config.h anymore for using LS's API header files
1126     - fixed warnings in API doc generation
1127 schoenebeck 1065
1128 schoenebeck 947 * general changes:
1129     - replaced the old, confusing MIDI program change mechanism by a
1130     flexible MIDI instrument mapper which allows to map arbitrary
1131 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1132 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1133     loaded on the respective channel when such MIDI program change
1134     messages arrive, beside that, each entry allows to define a life-time
1135     strategy for the instrument, so the user can define whether the
1136     instrument should i.e. be permanently loaded (to be able to switch
1137     quickly among sounds) or i.e. loaded just on demand when the
1138     respective program change arrives (to safe RAM space), as well as a
1139     global volume factor for each entry, so the user can adjust the volume
1140     dynamic of his mapped instrument collection without having to modify
1141 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1142     MIDI instrument maps and assign each sampler channel individually
1143     a certain map, so that i.e. separation of normal instruments and
1144     drumkits is possible
1145 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1146     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1147 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1148     due to a constant size RingBuffer FIFO which is now replaced by a
1149     dynamic (unlimited) size std::list FIFO
1150 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1151     output channels for being processed by external effect processors
1152     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1153     controllers
1154 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1155 iliev 1130 - Implemented new, improved notification system
1156 schoenebeck 1149 - fixed compilation errors regarding OSX
1157     (patch by Toshi Nagata)
1158 iliev 1161 - implemented instruments database
1159 iliev 1345 - added support for escape sequences to the instruments database
1160 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1161     within the sampler's process (by using instrument editor plugins),
1162     you'll notice the new "Registered instrument editors:" message on
1163 schoenebeck 1407 startup, added a new LSCP command:
1164     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1165 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1166     given sampler channel, the plugin path can be overridden at compile
1167     time with ./configure --enable-plugin-dir=/some/dir
1168 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1169     in the sampler's process to safely edit instruments while playing
1170     without a crash (hopefully) by either suspending single regions
1171     wherever possible or if unavoidable whole engine(s)
1172 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1173     policy and priority on thread level, set a minimum stack size for
1174     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1175     threads simply inherited properties of starting thread instead of
1176     setting their own policy and priority
1177 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1178     main process did not wait for the stack trace process to finish
1179     its output
1180 persson 1248 - fixed some minor memory leaks
1181 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1182     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1183 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1184     register, to avoid relocations in the text segment at runtime)
1185 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1186 schoenebeck 947
1187     * MIDI driver:
1188     - dispatch bank select (MSB and LSB) messages
1189    
1190 schoenebeck 1049 * audio driver:
1191     - the ALSA audio output driver parameters now reflect the correct
1192     parameter value ranges for the respective selected sound card
1193     (patch by Till Wimmer, a bit fixed and extended)
1194    
1195 persson 951 * Gigasampler format engine:
1196     - if a filter is used and EG2 finishes before EG1, let the voice
1197     die when EG2 has finished (this fixes a problem with clicks and
1198     voice starvation for some gigs)
1199 persson 1038 - playback is no longer disabled during instrument loading
1200     - all notes playing on a channel that changes its instrument keep
1201     playing with the old instrument until they get a note off
1202     command
1203 persson 1039 - EG fix: a release value of zero could cause noises or crash
1204 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1205 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1206     above max sustain level, which means that there is a decay phase
1207     even if sustain is 100%
1208 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1209     noises or crashes
1210 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1211 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1212     supplied to the configure script (fixes #46)
1213 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1214     instead of a fix value
1215 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1216     127 (solo mode) only kill voices if the respective mode really
1217     changed
1218 persson 951
1219 schoenebeck 1244 * LSCP server:
1220     - fixed compile time error for old Bison versions
1221     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1222 schoenebeck 1245 - parser now supports extended ASCII character set
1223     (up to ASCII code 255, i.e. includes now umlauts and accents)
1224     - filename arguments in LSCP commands now allow to use escape
1225     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1226     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1227     code value like \xf2) (fixes bug #24)
1228 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1229     least one of their text-based parameters (i.e. name, description):
1230     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1231     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1232     "SET DB_INSTRUMENT_DIRECTORY NAME",
1233     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1234     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1235     "FIND DB_INSTRUMENT_DIRECTORIES"
1236 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1237     occured, the unexpected character and the actually expected, possible
1238     character(s), the latter only if less than 5 possibilities)
1239 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1240     settings
1241 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1242     of strings were treated as being one string containing commas
1243     (fixes #57)
1244 schoenebeck 1244
1245 iliev 959 * Bug fixes:
1246     - fixed crash occurring on certain LSCP scripts (Bug 39)
1247 persson 1038 - another thread safety fix for lscp "load engine" and "set
1248     channel audio output device"
1249 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1250     on a sampler channel with connected MIDI device
1251 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1252     device connected to a sampler channel to number less then or equal
1253     to the index of the port to which the sampler channel is connected.
1254 iliev 1296 - The previous bindings were not been disconnected when altering
1255     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1256     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1257 iliev 1297 - The active stream/voice count statistic was incorrect.
1258 iliev 1298 - notification events were not been sent for some sampler
1259     channel changes
1260 iliev 1305 - added default min and max values to restrict the number of allowed
1261     audio output channels and MIDI input ports
1262 iliev 1306 - the connection to the PCM interface is now closed when destroying
1263     an audio output device
1264 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1265 iliev 959
1266 schoenebeck 1221 * test cases:
1267     - updated and fixed (haven't been touched in a while)
1268    
1269 schoenebeck 937 Version 0.4.0 (24 November 2006)
1270 persson 696
1271 schoenebeck 697 * packaging changes:
1272 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1273     to post-(un)install steps; added devel package for liblinuxsampler;
1274     to linuxsampler.spec (RPM)
1275 schoenebeck 697 - install necessary development header files for allowing 3rd party
1276     applications to link against liblinuxsampler
1277     - liblinuxsampler's API documentation can be generated with 'make docs'
1278     (Doxygen required)
1279 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1280     implementation (currently either an integer math solution or a
1281     di-harmonic approximation), automatic detection can be overriden
1282     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1283     configure script argument though (mandatory for cross-compilation)
1284 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1285     provided some on his own (as CXXFLAGS)
1286 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1287     messages
1288 schoenebeck 852 - added compile time options to allow disabling the various audio and
1289     MIDI drivers
1290 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1291     (patch by Ebrahim Mayat)
1292 schoenebeck 697
1293 persson 696 * Gigasampler format engine:
1294 schoenebeck 738 - extensive synthesis optimization
1295     (reimplementation of EGs and LFO(s), removed synthesis parameter
1296     prerendering and the synthesis parameter matrix in general, splitting
1297     each audio fragment into subfragments now where each subfragment uses
1298 persson 830 constant pitch and filter coefficients. The volume coefficient is
1299     linearly interpolated inside a subfragment, unless
1300     --disable-interpolate-volume is set.)
1301 persson 696 - fine tuning of the EG modulation parameters
1302 persson 729 - improved filter cutoff calculation by adding support for the
1303     following gig parameters: Cutoff freq (used when no cutoff
1304     controller is defined), Control invert, Minimum cutoff, Velocity
1305 persson 791 curve and Velocity range. The keyboard tracking now scales
1306     cutoff frequency instead of resonance.
1307 persson 877 - added support for gig parameter Resonance.
1308 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1309 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1310     which can be overridden with --enable-global-attenuation
1311 persson 783 - EG fixes: made the length of "attack hold" stage more
1312     accurate. Release stage can now start before attack stage
1313 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1314     time now has a minimal value to prevent clicks.
1315 persson 799 - fixed pitch changes larger than one octave
1316 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1317     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1318     all modes can be altered via standard GM messages, that is CC5 for
1319     altering portamento time, CC65 for enabling / disabling portamento
1320     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1321 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1322     parameter) and crossfade
1323 persson 831 - added support for the "attenuation controller threshold" gig
1324     parameter
1325 persson 832 - added smoothing of volume changes caused by control change
1326     messages
1327 persson 865 - sample loop parameters are now taken from the DimensionRegion
1328     instead of the wave chunk
1329     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1330     not equal to a power of two
1331 persson 877 - reimplementation of the filter algorithm. The new filter is more
1332     accurate and supports all gig filter types, including bandreject
1333     and lowpass turbo.
1334 persson 903 - real support for 24 bit samples - samples are not truncated to
1335     16 bits anymore
1336     - support for aftertouch (channel pressure, not polyphonic
1337     aftertouch)
1338 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1339     amplifying from 0)
1340 persson 696
1341 schoenebeck 711 * LSCP server:
1342     - fixed application exit on broken pipe error (fixes bug #20)
1343 iliev 793 - fixed the notification messages delay due to lack of
1344     network activity (fixes bug #26)
1345 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1346     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1347 schoenebeck 711
1348 schoenebeck 838 * audio driver:
1349     - added aRts audio output driver (by no means RT safe)
1350    
1351 schoenebeck 775 * MIDI driver:
1352     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1353     messages several times instead of once
1354 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1355     for events (i.e. for offline rendering based MIDI drivers)
1356 persson 922 - added checks for bad MIDI data
1357 schoenebeck 775
1358 schoenebeck 900 * linuxsampler application:
1359     - show available sampler engine types on startup
1360    
1361 schoenebeck 705 * general changes:
1362     - support for muting sampler channels and solo mode of the same, two new
1363     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1364     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1365     introduced for this, the behavior is the same like on a mixer console
1366 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1367     --enable-process-muted-channels which can be used to enable the
1368     processing of muted channels.
1369 iliev 777 - support for sostenuto pedal
1370 iliev 779 - support for monitoring the total number of active voices
1371 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1372     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1373 persson 835 - fixed some memory management errors
1374 persson 841 - fixed some concurrency problems that could lead to crashes when
1375     LSCP commands were executed
1376 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1377     sampler channel (fixes bug #36)
1378 schoenebeck 705
1379 schoenebeck 692 Version 0.3.3 (15 July 2005)
1380 schoenebeck 686
1381     * packaging changes:
1382     - fixed compilation with gcc 4.0
1383    
1384 schoenebeck 687 * Gigasampler format engine:
1385     - LFO preprocessing was performed even though the respective LFO was
1386     disabled by the instrument patch (minor efficiency fix)
1387 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1388     for volume ramp downs in the same fragment (needed for current voice
1389     stealing implementation) then simply inform the user with a warning
1390     about possible click sounds and reduce the volume ramp down
1391     appropriately instead of cancelling the audio device connection
1392 schoenebeck 687
1393 schoenebeck 677 Version 0.3.2 (24 June 2005)
1394 schoenebeck 609
1395     * packaging changes:
1396     - updated autotools build files to compile on OS X
1397     (conditional compilation of CoreMIDI and MidiShare drivers)
1398 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1399     './configure --disable-asm' (definitely not recommended)
1400 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1401     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1402     (due to 'dist-bzip2' automake option)
1403 schoenebeck 649
1404     * Gigasampler format engine:
1405     - support for the gig parameters for "release velocity response" curves
1406     - fine tuning of the EGADSR envelope
1407     - volume of release triggered samples now depends on note-on velocity,
1408     note length and gig parameter "release trigger decay" instead of
1409     note-off velocity.
1410 schoenebeck 663 - revised voice stealing
1411     (fixes crash and endless loop caused by voice stealing)
1412 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1413 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1414     instead of when the respective voice is actually launched
1415     (fixes undefined behavior if stolen voices belonged to a key group -
1416     this case was followed by a "killed voice survived" error message)
1417 schoenebeck 669 - fixed minor issue with null/silence samples
1418     (those stole voices even though they don't need a voice at all which
1419     resulted in "voice stealing didn't work out" messages)
1420 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1421     instrument or audio output device change
1422 schoenebeck 654
1423 schoenebeck 620 * LSCP server:
1424 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1425 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1426 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1427 schoenebeck 609
1428 schoenebeck 668 * linuxsampler application:
1429     - added command line parameters --lscp-addr and --lscp-port to override
1430     default IP address and port of LSCP server
1431    
1432 schoenebeck 579 Version 0.3.1 (24 May 2005)
1433    
1434     * initial release
