* sfz opcode 'sample': Added support for built-in sample '*silence'
  (fixes bug #310, patch by Jacek Roszkowski).
* sfz opcode 'sample': Show warning message for unknown or unsupported
  built-in sample types.
* Bumped version (2.1.0.svn7).

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 persson 3455 - Fixed compiler warnings.
12     - Fixed compilation error when cross-compiling to Mac.
13 schoenebeck 3444
14 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
15     - Format extension: If requested by instrument then don't play release
16     trigger sample on note-off events.
17    
18 schoenebeck 3487 * SFZ format engine:
19     - Fixed memory leak when releasing samples
20     (fixes bug #307, patch by Jacek Roszkowski)
21 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
22     (fixes bug #308, patch by Jacek Roszkowski).
23 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
24     (fixes bug #310, patch by Jacek Roszkowski).
25 schoenebeck 3487
26 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
27 persson 2837
28 persson 2856 * SFZ format engine:
29     - added support for <global>, <master> and #define (patch by Alby M)
30 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
31     - Added support for sfz extension opcode 'script' which may be used to
32     load real-time instrument script file (NKSP script language).
33 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
34 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
35 persson 3291 - sfz parser: allow missing space between header and opcode
36 persson 2856
37 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
38 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
39     cutoff settings.
40 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
41     all if an up-pitch of more than 40 semi tones was requested (I don't
42     think there is any stock gig sound that requires this behavior to
43     resemble its original sound).
44 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
45     be aborted (as LinuxSampler extension to the original GigaStudio 4
46     format).
47 schoenebeck 3072
48 persson 2837 * general changes:
49     - fixed printf type errors (mostly in debug messages)
50 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
51 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
52     allowing to sort data efficiently in real-time safe manner.
53     - RTList class: added methods for moving/inserting elements to arbitrary
54     position within a list.
55     - RTList class: added method fromPtr() for creating an Iterator object from
56     a raw element pointer.
57     - Attempt to partly fix resetting engine channels vs. resetting engine, an
58     overall cleanup of the Reset*(), ConnectAudioDevice(),
59     DisconnectAudioDevice() API methods would still be desirable though,
60     because the current situation is still inconsistent and error prone.
61 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
62     being directly assigned to a keyboard key. This allows more fine graded
63     processing of voices, which is i.e. required for certain instrument
64     script features.
65 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
66     (CC #64) events.
67     - Fix: Release trigger voices can now also distinguish correctly between
68     note-off and sustain pedal up events.
69 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
70     (while slow rate of crossfade smoother is preserved) to allow quick
71     volume and pan changes by instrument scripts for instance.
72 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
73     properly and thus were ignored for certain uses.
74 schoenebeck 3018 - Added new C++ API method
75     VirtualMidiDevice::SendChannelPressureToSampler().
76 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
77     sub threads is 16-byte aligned
78 schoenebeck 3054 - fixed numerous compiler warnings
79 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
80 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
81     fixes potential undefined behavior.
82 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
83     have a valid sample mapped (fixes bug #252).
84     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
85 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
86     subsequent optional argument due to glibc's implementation oddity
87     which expects a "=" sign, but no space between them.
88 persson 2837
89 schoenebeck 2866 * packaging changes:
90     - removed unnecessary dependency to libuuid
91     (originated by libgig's usage of it)
92 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
93     auto detect whether it (sh/c)ould output its messages in color.
94 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
95     substitution variable.
96     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
97 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
98     linuxsampler with instruments DB support.
99 schoenebeck 2866
100 schoenebeck 2871 * Real-time instrument scripts:
101     - Implemented scheduler for delayed MIDI events and for suspended scripts.
102     - Built-in script function "wait()": implemented support for function's
103     "duration-us" argument, thus scripts using this function are now
104     correctly resumed after the requested amount of microseconds.
105     - Built-in script function "play_note()": implemented support for
106     function's "duration-us" argument, thus notes triggered with this
107     argument are now correctly released after the requested amount of
108     microseconds.
109     - Fix: script events were not cleared when engine channel was reset,
110     potentially causing undefined behavior.
111     - Fixed crash which happened when trying to reference an undeclared
112     variable.
113 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
114     special value -1 for "duration-us" argument, which will cause the
115     triggered note to be released once the original note was released.
116 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
117     - Added new API method ScriptVM::syntaxHighlighting() which provides
118     a convenient syntax highlighting backend for external instrument
119     script editor applications.
120 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
121     - Extended parser issues to provide not only first line and first
122     column, but also last line and last column of issue (thus marking
123     the precise span of the issue within the source code).
124 schoenebeck 2902 - Reload script automatically after being modified by an instrument
125     editor.
126 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies

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

151     - NKSP language fix: division expressions were evaluated too often.
152     - NKSP language fix: string concatenation operator was right
153     associative instead of left (to right).
154 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
155     (i.e. "if end if").
156 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
157     - Implemented built-in script variable "$NI_CALLBACK_ID".
158     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
159     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

163     - Added built-in script constant "$NI_CB_TYPE_NOTE".
164     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

168     - Implemented built-in script function "change_decay()".
169     - Implemented built-in script function "change_release()".
170 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
171     synthesis parameter changes immediately in case the respective note
172     was triggered at the same time, instead of scheduling the parameter
173     change, especially because it would cause some parameter types's
174     changes either to be ramped (i.e. change_vol()) or other types even
175     to have not effect at all (i.e. change_attack()).
176 schoenebeck 2965 - Implemented built-in script function "sh_left()".
177     - Implemented built-in script function "sh_right()".
178 schoenebeck 2970 - Implemented built-in script function "min()".

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

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

230     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
231     - Implemented built-in script function "change_vol_curve()".
232     - Implemented built-in script function "change_tune_curve()".
233 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
234     offset with argument 3, where special value -1 means to use the regular
235     sample offset as defined by the instrument file.
236 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
237     - Built-in variable $EVENT_NOTE is now a read-only variable.
238     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
239     - built-in "play_note()" function now accepts -2 for its fourth argument
240     (note duration) which means the life time of the note shall be sticked
241     to the requested note number of argument 1.
242     - Fix: built-in "play_note()" function now returns 0 as result value if
243     -1 was passed for its fourth argument (note duration) and the respective
244     parent note is already gone.
245 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
246 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

253     another script handler by passing its callback ID.
254 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
255     "init" event handlers.
256 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
257     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
258     to retrieve all code blocks filtered out by the preprocessor.
259 schoenebeck 3293 - Added built-in script function "fork()".
260     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
261     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
262     - Fixed potential crash when accessing dynamic built-in array variables.

264     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
265     - Added built-in constant $CALLBACK_STATUS_QUEUE.
266     - Added built-in constant $CALLBACK_STATUS_RUNNING.
267 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
268     "change_decay()" and "change_release()" to i.e. allow passing 2000000
269     for doubling the respective time.
270 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
271     to a lexer start condition stack underrun.
272     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
273     USE_CODE_IF_NOT() preprocessor statements.
274 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
275     can be set to disable all subsequent built-in "message()" function calls
276     on preprocessor level.
277 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
278 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
279     to avoid the editor app to crash on ill-formed text input.
280 schoenebeck 3335 - Added built-in script function "change_pan_time()".
281     - Added built-in script function "change_pan_curve()".

339 persson 2086 * general changes:
340 iliev 2012 - Refactoring: moved the independent code from
341     the Gigasampler format engine to base classes
342 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
343     respective profiling code is currently broken
344 schoenebeck 2053 - Introduced support for optional environment variable
345     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
346     where the sampler shall look for instrument editor plugins

349     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
350     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per

353     effect type is)
354     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
355     note (in this implementation of the sampler its simply hard routed to
356     the 2nd effect send of the sampler channel, no matter what the actual
357     effect type is)

366     allowing to retrieve the whole list of files used for the loaded
367     instrument on an engine channel (a.k.a. part). Some GigaStudio
368     instruments for example are splitted over several files like
369     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
370 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
371     - Added new C++ API method Sampler::GetGlobalMaxStreams().
372     - Added new C++ API method Sampler::SetGlobalMaxVoices().
373     - Added new C++ API method Sampler::SetGlobalMaxStreams().
374 schoenebeck 2377 - Various "const" and "restrict" optimizations.
375 persson 2382 - all engines: add pan CC value to instrument pan parameter before
376     applying panning, instead of using two separate pan functions in
377     series (#182)
378 persson 2427 - added a lock guard class for exception safe mutex handling and
379     used it everywhere appropriate
380 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
381     - Exposed scale tuning to C++ API (along to the already existing standard
382     SysEx way).
383 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
384     and broken for ppc64. (Seq_cst loads and stores are actually not
385     used in LS, so the bug wasn't noticable.)
386     - lsatomic.h: added ARMv7 support
387 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
388     added various new C++ methods for this new feature / design change, old
389     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
390     as deprecated but are still there and should provide full behavior
391     backward compatibility).
392     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
393     unsafe and caused compilation error with clang 2.x).
394 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
395 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
396     sampler from the command line by providing LSCP aware features.
397 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
398     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
399     - VirtualMidiDevice: Added support for pitch bend.
400 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
401     polyphonic key pressure events (so far polyphonic pressure was not
402     supported at all, and channel pressure was rerouted as CC128 but not
403     used so far).
404 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
405     code is shared by all sampler engine implemementations, however only the
406     gig file format currently provides support for storing instrument scripts
407     (as LinuxSampler extension to the original GigaStudio 4 format).

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

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

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

893     a pointer to the launched InstrumentEditor object
894 schoenebeck 1876 - added optional 3rd party user data parameter for following

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

958     instrument database compilable
959 schoenebeck 1930 - added instrument database support on Windows
960     works with both standalone mode and VST plugin.
961     the instruments DB file is located in
962     %USERPROFILE%\.linuxsampler\instruments.db which allows different

973 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
974     enough for piano gigs with pedal noise samples
975 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
976     respective FX send MIDI controller was used
977 schoenebeck 1724 - added support for GM global device volume SysEx message
978 schoenebeck 1762 (can be selected at compile time to either apply globally to the

980     connected to the respective MIDI input port the SysEx message arrived
981     on)
982 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
983     sometimes wrongly killed in the same buffer, causing no sound to
984     be played
985 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
986     which is usally used to switch a part between chromatic sounds and
987     drumkit sounds (as opposed to their common default setting of MIDI
988     part 10 being a drumkit part and all other ones chromatic parts), in
989     LS however one can switch between the first 16 MIDI instrument maps
990     defined for the sampler
991 persson 1764 - made it possible to create multiple sample channels even if the
992     audio thread isn't running

998     e.g. when a sample was added while playing (#82)
999 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1000     same time stamp as the voice's note-on event and occured both in the

1002 persson 1858 - added support for the "fine tune" and "pitch bend range"
1003     instrument-level gig parameters

1009     note was silent
1010 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1011     same time a new instrument was loading
1012 persson 1644
1013 schoenebeck 1687 * LSCP server:
1014     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

1025     KEY_BINDINGS and KEYSWITCH_BINDINGS
1026 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1027     was incorrect
1028 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1029 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1030     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1031     be triggered respectively
1032     - added new LSCP command "SET STREAMS" to globally alter the maximum
1033     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1034     which will be triggered respectively

1061     PowerPC, which probably could cause crashes on that platform
1062 persson 1889 - fixed a memory management error which could cause a crash when a
1063     plugin was unloaded
1064 persson 1896 - bugfix: two private structs had the same name, which could cause
1065     problems if the linker chose the wrong constructor
1066 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1067     Windows

1070 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1071 schoenebeck 1454
1072     * packaging changes:
1073     - added autoconf checks for pthread library
1074     - added autoconf check for pthread bug found on certain NPTL-enabled
1075     glibc versions (see Gentoo bug report #194076)
1076 senoner 1502 - added autoconf checks for MS Windows
1077 schoenebeck 1454
1078 persson 1455 * general changes:
1079     - bugfix: the thread used by an editor plugin didn't die when the
1080     editor closed
1081 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1082     out all the space. operator--() did not apply size_mask after
1083     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1084     order to avoid problems with the _NonVolatileReader functions.
1085     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1086     GetWriteSpace(). Since this function is currently only used in
1087     the stream's qsort() compare function, it didn't trigger any
1088     bugs.
1089     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1090     24bit mode too. Faster method to read 24bit words on little
1091     endian machines (x86): replaced 3 byte reads + shifts with a 1
1092     unaligned 32bit read and shift
1093     - experimental support for MS Windows (MIDI input via MME, AUDIO
1094     output via ASIO)
1095     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1096 iliev 1541 - support for monitoring the total number of active disk streams
1097     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1098     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1099 persson 1455
1100 senoner 1500 * AUDIO driver:
1101 persson 1534 - added Windows ASIO low latency audio driver
1102 senoner 1500
1103 senoner 1485 * MIDI driver:
1104 schoenebeck 1495 - added MME Windows MIDI driver
1105 senoner 1485
1106 schoenebeck 1471 * LSCP server:
1107     - added support for Windows style path / filenames, however with
1108     forward slash path separators instead of backslash
1109     (i.e. "C:/foo/bar.gig")
1110 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1111     apostrophes as well
1112 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1113     "LIST FILE INSTRUMENTS <file>" and
1114     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1115     about an arbitrary instrument file on the system where the sampler is
1116     running on
1117 schoenebeck 1471
1118 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1119 schoenebeck 947
1120 schoenebeck 1065 * packaging changes:
1121 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1122     API header files anymore
1123 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1124     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1125 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1126     capable to execute our autoconf environment, thus no need anymore
1127     to maintain the compile time configuration file (osx/version.h) for
1128     OSX manually (patch by Toshi Nagata)
1129 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1130     parameters
1131 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1132     C++ API header files, all implementation internal global definitions
1133     are now in global_private.h
1134     - atomic.h is not exposed to the C++ API anymore
1135     - no need to include config.h anymore for using LS's API header files
1136     - fixed warnings in API doc generation
1137 schoenebeck 1065
1138 schoenebeck 947 * general changes:
1139     - replaced the old, confusing MIDI program change mechanism by a
1140     flexible MIDI instrument mapper which allows to map arbitrary
1141 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1142 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1143     loaded on the respective channel when such MIDI program change
1144     messages arrive, beside that, each entry allows to define a life-time
1145     strategy for the instrument, so the user can define whether the
1146     instrument should i.e. be permanently loaded (to be able to switch
1147     quickly among sounds) or i.e. loaded just on demand when the
1148     respective program change arrives (to safe RAM space), as well as a
1149     global volume factor for each entry, so the user can adjust the volume
1150     dynamic of his mapped instrument collection without having to modify
1151 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1152     MIDI instrument maps and assign each sampler channel individually
1153     a certain map, so that i.e. separation of normal instruments and
1154     drumkits is possible
1155 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1156     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1157 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1158     due to a constant size RingBuffer FIFO which is now replaced by a
1159     dynamic (unlimited) size std::list FIFO
1160 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1161     output channels for being processed by external effect processors
1162     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1163     controllers
1164 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1165 iliev 1130 - Implemented new, improved notification system
1166 schoenebeck 1149 - fixed compilation errors regarding OSX
1167     (patch by Toshi Nagata)
1168 iliev 1161 - implemented instruments database
1169 iliev 1345 - added support for escape sequences to the instruments database
1170 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1171     within the sampler's process (by using instrument editor plugins),
1172     you'll notice the new "Registered instrument editors:" message on
1173 schoenebeck 1407 startup, added a new LSCP command:
1174     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1175 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1176     given sampler channel, the plugin path can be overridden at compile
1177     time with ./configure --enable-plugin-dir=/some/dir
1178 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1179     in the sampler's process to safely edit instruments while playing
1180     without a crash (hopefully) by either suspending single regions
1181     wherever possible or if unavoidable whole engine(s)
1182 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1183     policy and priority on thread level, set a minimum stack size for
1184     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1185     threads simply inherited properties of starting thread instead of
1186     setting their own policy and priority
1187 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1188     main process did not wait for the stack trace process to finish
1189     its output
1190 persson 1248 - fixed some minor memory leaks
1191 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1192     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1193 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1194     register, to avoid relocations in the text segment at runtime)
1195 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1196 schoenebeck 947
1197     * MIDI driver:
1198     - dispatch bank select (MSB and LSB) messages
1199    
1200 schoenebeck 1049 * audio driver:
1201     - the ALSA audio output driver parameters now reflect the correct
1202     parameter value ranges for the respective selected sound card
1203     (patch by Till Wimmer, a bit fixed and extended)
1204    
1205 persson 951 * Gigasampler format engine:
1206     - if a filter is used and EG2 finishes before EG1, let the voice
1207     die when EG2 has finished (this fixes a problem with clicks and
1208     voice starvation for some gigs)
1209 persson 1038 - playback is no longer disabled during instrument loading
1210     - all notes playing on a channel that changes its instrument keep
1211     playing with the old instrument until they get a note off
1212     command
1213 persson 1039 - EG fix: a release value of zero could cause noises or crash
1214 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1215 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1216     above max sustain level, which means that there is a decay phase
1217     even if sustain is 100%
1218 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1219     noises or crashes
1220 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1221 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1222     supplied to the configure script (fixes #46)
1223 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1224     instead of a fix value
1225 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1226     127 (solo mode) only kill voices if the respective mode really
1227     changed
1228 persson 951
1229 schoenebeck 1244 * LSCP server:
1230     - fixed compile time error for old Bison versions
1231     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1232 schoenebeck 1245 - parser now supports extended ASCII character set
1233     (up to ASCII code 255, i.e. includes now umlauts and accents)
1234     - filename arguments in LSCP commands now allow to use escape
1235     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1236     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1237     code value like \xf2) (fixes bug #24)
1238 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1239     least one of their text-based parameters (i.e. name, description):
1240     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1241     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1242     "SET DB_INSTRUMENT_DIRECTORY NAME",
1243     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1244     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1245     "FIND DB_INSTRUMENT_DIRECTORIES"
1246 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1247     occured, the unexpected character and the actually expected, possible
1248     character(s), the latter only if less than 5 possibilities)
1249 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1250     settings
1251 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1252     of strings were treated as being one string containing commas
1253     (fixes #57)
1254 schoenebeck 1244
1255 iliev 959 * Bug fixes:
1256     - fixed crash occurring on certain LSCP scripts (Bug 39)
1257 persson 1038 - another thread safety fix for lscp "load engine" and "set
1258     channel audio output device"
1259 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1260     on a sampler channel with connected MIDI device
1261 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1262     device connected to a sampler channel to number less then or equal
1263     to the index of the port to which the sampler channel is connected.
1264 iliev 1296 - The previous bindings were not been disconnected when altering
1265     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1266     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1267 iliev 1297 - The active stream/voice count statistic was incorrect.
1268 iliev 1298 - notification events were not been sent for some sampler
1269     channel changes
1270 iliev 1305 - added default min and max values to restrict the number of allowed
1271     audio output channels and MIDI input ports
1272 iliev 1306 - the connection to the PCM interface is now closed when destroying
1273     an audio output device
1274 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1275 iliev 959
1276 schoenebeck 1221 * test cases:
1277     - updated and fixed (haven't been touched in a while)
1278    
1279 schoenebeck 937 Version 0.4.0 (24 November 2006)
1280 persson 696
1281 schoenebeck 697 * packaging changes:
1282 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1283     to post-(un)install steps; added devel package for liblinuxsampler;
1284     to linuxsampler.spec (RPM)
1285 schoenebeck 697 - install necessary development header files for allowing 3rd party
1286     applications to link against liblinuxsampler
1287     - liblinuxsampler's API documentation can be generated with 'make docs'
1288     (Doxygen required)
1289 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1290     implementation (currently either an integer math solution or a
1291     di-harmonic approximation), automatic detection can be overriden
1292     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1293     configure script argument though (mandatory for cross-compilation)
1294 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1295     provided some on his own (as CXXFLAGS)
1296 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1297     messages
1298 schoenebeck 852 - added compile time options to allow disabling the various audio and
1299     MIDI drivers
1300 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1301     (patch by Ebrahim Mayat)
1302 schoenebeck 697
1303 persson 696 * Gigasampler format engine:
1304 schoenebeck 738 - extensive synthesis optimization
1305     (reimplementation of EGs and LFO(s), removed synthesis parameter
1306     prerendering and the synthesis parameter matrix in general, splitting
1307     each audio fragment into subfragments now where each subfragment uses
1308 persson 830 constant pitch and filter coefficients. The volume coefficient is
1309     linearly interpolated inside a subfragment, unless
1310     --disable-interpolate-volume is set.)
1311 persson 696 - fine tuning of the EG modulation parameters
1312 persson 729 - improved filter cutoff calculation by adding support for the
1313     following gig parameters: Cutoff freq (used when no cutoff
1314     controller is defined), Control invert, Minimum cutoff, Velocity
1315 persson 791 curve and Velocity range. The keyboard tracking now scales
1316     cutoff frequency instead of resonance.
1317 persson 877 - added support for gig parameter Resonance.
1318 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1319 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1320     which can be overridden with --enable-global-attenuation
1321 persson 783 - EG fixes: made the length of "attack hold" stage more
1322     accurate. Release stage can now start before attack stage
1323 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1324     time now has a minimal value to prevent clicks.
1325 persson 799 - fixed pitch changes larger than one octave
1326 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1327     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1328     all modes can be altered via standard GM messages, that is CC5 for
1329     altering portamento time, CC65 for enabling / disabling portamento
1330     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1331 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1332     parameter) and crossfade
1333 persson 831 - added support for the "attenuation controller threshold" gig
1334     parameter
1335 persson 832 - added smoothing of volume changes caused by control change
1336     messages
1337 persson 865 - sample loop parameters are now taken from the DimensionRegion
1338     instead of the wave chunk
1339     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1340     not equal to a power of two
1341 persson 877 - reimplementation of the filter algorithm. The new filter is more
1342     accurate and supports all gig filter types, including bandreject
1343     and lowpass turbo.
1344 persson 903 - real support for 24 bit samples - samples are not truncated to
1345     16 bits anymore
1346     - support for aftertouch (channel pressure, not polyphonic
1347     aftertouch)
1348 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1349     amplifying from 0)
1350 persson 696
1351 schoenebeck 711 * LSCP server:
1352     - fixed application exit on broken pipe error (fixes bug #20)
1353 iliev 793 - fixed the notification messages delay due to lack of
1354     network activity (fixes bug #26)
1355 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1356     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1357 schoenebeck 711
1358 schoenebeck 838 * audio driver:
1359     - added aRts audio output driver (by no means RT safe)
1360    
1361 schoenebeck 775 * MIDI driver:
1362     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1363     messages several times instead of once
1364 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1365     for events (i.e. for offline rendering based MIDI drivers)
1366 persson 922 - added checks for bad MIDI data
1367 schoenebeck 775
1368 schoenebeck 900 * linuxsampler application:
1369     - show available sampler engine types on startup
1370    
1371 schoenebeck 705 * general changes:
1372     - support for muting sampler channels and solo mode of the same, two new
1373     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1374     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1375     introduced for this, the behavior is the same like on a mixer console
1376 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1377     --enable-process-muted-channels which can be used to enable the
1378     processing of muted channels.
1379 iliev 777 - support for sostenuto pedal
1380 iliev 779 - support for monitoring the total number of active voices
1381 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1382     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1383 persson 835 - fixed some memory management errors
1384 persson 841 - fixed some concurrency problems that could lead to crashes when
1385     LSCP commands were executed
1386 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1387     sampler channel (fixes bug #36)
1388 schoenebeck 705
1389 schoenebeck 692 Version 0.3.3 (15 July 2005)
1390 schoenebeck 686
1391     * packaging changes:
1392     - fixed compilation with gcc 4.0
1393    
1394 schoenebeck 687 * Gigasampler format engine:
1395     - LFO preprocessing was performed even though the respective LFO was
1396     disabled by the instrument patch (minor efficiency fix)
1397 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1398     for volume ramp downs in the same fragment (needed for current voice
1399     stealing implementation) then simply inform the user with a warning
1400     about possible click sounds and reduce the volume ramp down
1401     appropriately instead of cancelling the audio device connection
1402 schoenebeck 687
1403 schoenebeck 677 Version 0.3.2 (24 June 2005)
1404 schoenebeck 609
1405     * packaging changes:
1406     - updated autotools build files to compile on OS X
1407     (conditional compilation of CoreMIDI and MidiShare drivers)
1408 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1409     './configure --disable-asm' (definitely not recommended)
1410 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1411     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1412     (due to 'dist-bzip2' automake option)
1413 schoenebeck 649
1414     * Gigasampler format engine:
1415     - support for the gig parameters for "release velocity response" curves
1416     - fine tuning of the EGADSR envelope
1417     - volume of release triggered samples now depends on note-on velocity,
1418     note length and gig parameter "release trigger decay" instead of
1419     note-off velocity.
1420 schoenebeck 663 - revised voice stealing
1421     (fixes crash and endless loop caused by voice stealing)
1422 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1423 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1424     instead of when the respective voice is actually launched
1425     (fixes undefined behavior if stolen voices belonged to a key group -
1426     this case was followed by a "killed voice survived" error message)
1427 schoenebeck 669 - fixed minor issue with null/silence samples
1428     (those stole voices even though they don't need a voice at all which
1429     resulted in "voice stealing didn't work out" messages)
1430 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1431     instrument or audio output device change
1432 schoenebeck 654
1433 schoenebeck 620 * LSCP server:
