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

109     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
110     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
111     "event_status()" function.
112     - NKSP language: Added support for bitwise operators ".or.", ".and."
113     and ".not.".
114     - NKSP language scanner: Fixed IDs matching to require at least one
115     character (i.e. when matching function names or variable names).
116     - NKSP language scanner: disabled unusued rules.
117 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
118     be distinguished engine internally from "real" MIDI note on/off
119     events in order to avoid misbehaviors like hanging notes.
120 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
121     - Implemented built-in script variable "$NKSP_REAL_TIMER".
122     - Implemented built-in script variable "$NKSP_PERF_TIMER".
123     - Implemented built-in script variable "$ENGINE_UPTIME".
124 schoenebeck 2945 - Implemented built-in script function "inc()".
125     - Implemented built-in script function "dec()".
126     - NKSP language fix: division expressions were evaluated too often.
127     - NKSP language fix: string concatenation operator was right
128     associative instead of left (to right).
129 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
130     (i.e. "if end if").
131 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
132     - Implemented built-in script variable "$NI_CALLBACK_ID".
133     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
134     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

143     - Implemented built-in script function "change_decay()".
144     - Implemented built-in script function "change_release()".
145 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
146     synthesis parameter changes immediately in case the respective note
147     was triggered at the same time, instead of scheduling the parameter
148     change, especially because it would cause some parameter types's
149     changes either to be ramped (i.e. change_vol()) or other types even
150     to have not effect at all (i.e. change_attack()).
151 schoenebeck 2965 - Implemented built-in script function "sh_left()".
152     - Implemented built-in script function "sh_right()".
153 schoenebeck 2970 - Implemented built-in script function "min()".

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

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

202 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
203     available for gig format engine).
204 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
205     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
206     - Implemented built-in script function "change_vol_curve()".
207     - Implemented built-in script function "change_tune_curve()".
208 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
209     offset with argument 3, where special value -1 means to use the regular
210     sample offset as defined by the instrument file.
211 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
212     - Built-in variable $EVENT_NOTE is now a read-only variable.
213     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
214     - built-in "play_note()" function now accepts -2 for its fourth argument
215     (note duration) which means the life time of the note shall be sticked
216     to the requested note number of argument 1.
217     - Fix: built-in "play_note()" function now returns 0 as result value if
218     -1 was passed for its fourth argument (note duration) and the respective
219     parent note is already gone.
220 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
221 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
222     - NKSP language: Raise parser warning if array variable is accessed with

228     another script handler by passing its callback ID.
229 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
230     "init" event handlers.
231 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
232     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
233     to retrieve all code blocks filtered out by the preprocessor.
234 schoenebeck 3293 - Added built-in script function "fork()".
235     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
236     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
237     - Fixed potential crash when accessing dynamic built-in array variables.
238 schoenebeck 3296 - Added built-in script function "callback_status()".
239     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
240     - Added built-in constant $CALLBACK_STATUS_QUEUE.
241     - Added built-in constant $CALLBACK_STATUS_RUNNING.
242 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
243     "change_decay()" and "change_release()" to i.e. allow passing 2000000
244     for doubling the respective time.
245 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
246     to a lexer start condition stack underrun.
247     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
248     USE_CODE_IF_NOT() preprocessor statements.
249 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
250     can be set to disable all subsequent built-in "message()" function calls
251     on preprocessor level.
252 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
253 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
254     to avoid the editor app to crash on ill-formed text input.
255 schoenebeck 3335 - Added built-in script function "change_pan_time()".
256     - Added built-in script function "change_pan_curve()".

313 persson 2382
314 persson 2086 * general changes:
315 iliev 2012 - Refactoring: moved the independent code from
316     the Gigasampler format engine to base classes
317 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
318     respective profiling code is currently broken
319 schoenebeck 2053 - Introduced support for optional environment variable
320     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
321     where the sampler shall look for instrument editor plugins
322     (patch by Luis Garrido, slightly modified).
323 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
324     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
325     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
326     note (in this implementation of the sampler its simply hard routed to
327     the 1st effect send of the sampler channel, no matter what the actual
328     effect type is)
329     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
330     note (in this implementation of the sampler its simply hard routed to
331     the 2nd effect send of the sampler channel, no matter what the actual
332     effect type is)
333 schoenebeck 2124 - implemented support for internal LADSPA effects
334 schoenebeck 2140 - raised limit of program change queue from 100 to 512
335     (as suggested by Alex Stone)
336 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
337 iliev 2296 - experimental support for per voice equalization
338 iliev 2306 - added command line option --exec-after-init
339 schoenebeck 2330 - Introduced new C++ API method:
340     EngineChannel::InstrumentFileName(int index)
341     allowing to retrieve the whole list of files used for the loaded
342     instrument on an engine channel (a.k.a. part). Some GigaStudio
343     instruments for example are splitted over several files like
344     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
345 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
346     - Added new C++ API method Sampler::GetGlobalMaxStreams().
347     - Added new C++ API method Sampler::SetGlobalMaxVoices().
348     - Added new C++ API method Sampler::SetGlobalMaxStreams().
349 schoenebeck 2377 - Various "const" and "restrict" optimizations.
350 persson 2382 - all engines: add pan CC value to instrument pan parameter before
351     applying panning, instead of using two separate pan functions in
352     series (#182)
353 persson 2427 - added a lock guard class for exception safe mutex handling and
354     used it everywhere appropriate
355 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
356     - Exposed scale tuning to C++ API (along to the already existing standard
357     SysEx way).
358 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
359     and broken for ppc64. (Seq_cst loads and stores are actually not
360     used in LS, so the bug wasn't noticable.)
361     - lsatomic.h: added ARMv7 support
362 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
363     added various new C++ methods for this new feature / design change, old
364     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
365     as deprecated but are still there and should provide full behavior
366     backward compatibility).
367     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
368     unsafe and caused compilation error with clang 2.x).
369 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
370 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
371     sampler from the command line by providing LSCP aware features.
372 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
373     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
374     - VirtualMidiDevice: Added support for pitch bend.
375 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
376     polyphonic key pressure events (so far polyphonic pressure was not
377     supported at all, and channel pressure was rerouted as CC128 but not
378     used so far).
379 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
380     code is shared by all sampler engine implemementations, however only the
381     gig file format currently provides support for storing instrument scripts
382     (as LinuxSampler extension to the original GigaStudio 4 format).

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

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

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

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

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

933     instrument database compilable
934 schoenebeck 1930 - added instrument database support on Windows
935     works with both standalone mode and VST plugin.
936     the instruments DB file is located in
937     %USERPROFILE%\.linuxsampler\instruments.db which allows different

942 iliev 1603
943 persson 1644 * Gigasampler format engine:

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

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

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

1000     KEY_BINDINGS and KEYSWITCH_BINDINGS
1001 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1002     was incorrect
1003 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1004 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1005     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1006     be triggered respectively
1007     - added new LSCP command "SET STREAMS" to globally alter the maximum
1008     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1009     which will be triggered respectively

1056 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1057     out all the space. operator--() did not apply size_mask after
1058     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1059     order to avoid problems with the _NonVolatileReader functions.
1060     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1061     GetWriteSpace(). Since this function is currently only used in
1062     the stream's qsort() compare function, it didn't trigger any
1063     bugs.
1064     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1065     24bit mode too. Faster method to read 24bit words on little
1066     endian machines (x86): replaced 3 byte reads + shifts with a 1
1067     unaligned 32bit read and shift
1068     - experimental support for MS Windows (MIDI input via MME, AUDIO
1069     output via ASIO)
1070     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1071 iliev 1541 - support for monitoring the total number of active disk streams
1072     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1073     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1074 persson 1455
1075 senoner 1500 * AUDIO driver:
1076 persson 1534 - added Windows ASIO low latency audio driver
1077 senoner 1500
1078 senoner 1485 * MIDI driver:
1079 schoenebeck 1495 - added MME Windows MIDI driver
1080 senoner 1485
1081 schoenebeck 1471 * LSCP server:
1082     - added support for Windows style path / filenames, however with
1083     forward slash path separators instead of backslash
1084     (i.e. "C:/foo/bar.gig")
1085 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1086     apostrophes as well
1087 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1088     "LIST FILE INSTRUMENTS <file>" and
1089     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1090     about an arbitrary instrument file on the system where the sampler is
1091     running on
1092 schoenebeck 1471
1093 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1094 schoenebeck 947
1095 schoenebeck 1065 * packaging changes:
1096 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1097     API header files anymore
1098 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1099     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1100 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1101     capable to execute our autoconf environment, thus no need anymore
1102     to maintain the compile time configuration file (osx/version.h) for
1103     OSX manually (patch by Toshi Nagata)
1104 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1105     parameters
1106 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1107     C++ API header files, all implementation internal global definitions
1108     are now in global_private.h
1109     - atomic.h is not exposed to the C++ API anymore
1110     - no need to include config.h anymore for using LS's API header files
1111     - fixed warnings in API doc generation
1112 schoenebeck 1065
1113 schoenebeck 947 * general changes:
1114     - replaced the old, confusing MIDI program change mechanism by a
1115     flexible MIDI instrument mapper which allows to map arbitrary
1116 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1117 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1118     loaded on the respective channel when such MIDI program change
1119     messages arrive, beside that, each entry allows to define a life-time
1120     strategy for the instrument, so the user can define whether the
1121     instrument should i.e. be permanently loaded (to be able to switch
1122     quickly among sounds) or i.e. loaded just on demand when the
1123     respective program change arrives (to safe RAM space), as well as a
1124     global volume factor for each entry, so the user can adjust the volume
1125     dynamic of his mapped instrument collection without having to modify
1126 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1127     MIDI instrument maps and assign each sampler channel individually
1128     a certain map, so that i.e. separation of normal instruments and
1129     drumkits is possible
1130 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1131     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1132 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1133     due to a constant size RingBuffer FIFO which is now replaced by a
1134     dynamic (unlimited) size std::list FIFO
1135 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1136     output channels for being processed by external effect processors
1137     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1138     controllers
1139 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1140 iliev 1130 - Implemented new, improved notification system
1141 schoenebeck 1149 - fixed compilation errors regarding OSX
1142     (patch by Toshi Nagata)
1143 iliev 1161 - implemented instruments database
1144 iliev 1345 - added support for escape sequences to the instruments database
1145 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1146     within the sampler's process (by using instrument editor plugins),
1147     you'll notice the new "Registered instrument editors:" message on
1148 schoenebeck 1407 startup, added a new LSCP command:
1149     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1150 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1151     given sampler channel, the plugin path can be overridden at compile
1152     time with ./configure --enable-plugin-dir=/some/dir
1153 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1154     in the sampler's process to safely edit instruments while playing
1155     without a crash (hopefully) by either suspending single regions
1156     wherever possible or if unavoidable whole engine(s)
1157 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1158     policy and priority on thread level, set a minimum stack size for
1159     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1160     threads simply inherited properties of starting thread instead of
1161     setting their own policy and priority
1162 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1163     main process did not wait for the stack trace process to finish
1164     its output
1165 persson 1248 - fixed some minor memory leaks
1166 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1167     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1168 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1169     register, to avoid relocations in the text segment at runtime)
1170 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1171 schoenebeck 947
1172     * MIDI driver:
1173     - dispatch bank select (MSB and LSB) messages
1174    
1175 schoenebeck 1049 * audio driver:
1176     - the ALSA audio output driver parameters now reflect the correct
1177     parameter value ranges for the respective selected sound card
1178     (patch by Till Wimmer, a bit fixed and extended)
1179    
1180 persson 951 * Gigasampler format engine:
1181     - if a filter is used and EG2 finishes before EG1, let the voice
1182     die when EG2 has finished (this fixes a problem with clicks and
1183     voice starvation for some gigs)
1184 persson 1038 - playback is no longer disabled during instrument loading
1185     - all notes playing on a channel that changes its instrument keep
1186     playing with the old instrument until they get a note off
1187     command
1188 persson 1039 - EG fix: a release value of zero could cause noises or crash
1189 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1190 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1191     above max sustain level, which means that there is a decay phase
1192     even if sustain is 100%
1193 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1194     noises or crashes
1195 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1196 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1197     supplied to the configure script (fixes #46)
1198 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1199     instead of a fix value
1200 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1201     127 (solo mode) only kill voices if the respective mode really
1202     changed
1203 persson 951
1204 schoenebeck 1244 * LSCP server:
1205     - fixed compile time error for old Bison versions
1206     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1207 schoenebeck 1245 - parser now supports extended ASCII character set
1208     (up to ASCII code 255, i.e. includes now umlauts and accents)
1209     - filename arguments in LSCP commands now allow to use escape
1210     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1211     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1212     code value like \xf2) (fixes bug #24)
1213 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1214     least one of their text-based parameters (i.e. name, description):
1215     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1216     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1217     "SET DB_INSTRUMENT_DIRECTORY NAME",
1218     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1219     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1220     "FIND DB_INSTRUMENT_DIRECTORIES"
1221 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1222     occured, the unexpected character and the actually expected, possible
1223     character(s), the latter only if less than 5 possibilities)
1224 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1225     settings
1226 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1227     of strings were treated as being one string containing commas
1228     (fixes #57)
1229 schoenebeck 1244
1230 iliev 959 * Bug fixes:
1231     - fixed crash occurring on certain LSCP scripts (Bug 39)
1232 persson 1038 - another thread safety fix for lscp "load engine" and "set
1233     channel audio output device"
1234 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1235     on a sampler channel with connected MIDI device
1236 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1237     device connected to a sampler channel to number less then or equal
1238     to the index of the port to which the sampler channel is connected.
1239 iliev 1296 - The previous bindings were not been disconnected when altering
1240     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1241     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1242 iliev 1297 - The active stream/voice count statistic was incorrect.
1243 iliev 1298 - notification events were not been sent for some sampler
1244     channel changes
1245 iliev 1305 - added default min and max values to restrict the number of allowed
1246     audio output channels and MIDI input ports
1247 iliev 1306 - the connection to the PCM interface is now closed when destroying
1248     an audio output device
1249 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1250 iliev 959
1251 schoenebeck 1221 * test cases:
1252     - updated and fixed (haven't been touched in a while)
1253    
1254 schoenebeck 937 Version 0.4.0 (24 November 2006)
1255 persson 696
1256 schoenebeck 697 * packaging changes:
1257 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1258     to post-(un)install steps; added devel package for liblinuxsampler;
1259     to linuxsampler.spec (RPM)
1260 schoenebeck 697 - install necessary development header files for allowing 3rd party
1261     applications to link against liblinuxsampler
1262     - liblinuxsampler's API documentation can be generated with 'make docs'
1263     (Doxygen required)
1264 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1265     implementation (currently either an integer math solution or a
1266     di-harmonic approximation), automatic detection can be overriden
1267     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1268     configure script argument though (mandatory for cross-compilation)
1269 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1270     provided some on his own (as CXXFLAGS)
1271 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1272     messages
1273 schoenebeck 852 - added compile time options to allow disabling the various audio and
1274     MIDI drivers
1275 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1276     (patch by Ebrahim Mayat)
1277 schoenebeck 697
1278 persson 696 * Gigasampler format engine:
1279 schoenebeck 738 - extensive synthesis optimization
1280     (reimplementation of EGs and LFO(s), removed synthesis parameter
1281     prerendering and the synthesis parameter matrix in general, splitting
1282     each audio fragment into subfragments now where each subfragment uses
1283 persson 830 constant pitch and filter coefficients. The volume coefficient is
1284     linearly interpolated inside a subfragment, unless
1285     --disable-interpolate-volume is set.)
1286 persson 696 - fine tuning of the EG modulation parameters
1287 persson 729 - improved filter cutoff calculation by adding support for the
1288     following gig parameters: Cutoff freq (used when no cutoff
1289     controller is defined), Control invert, Minimum cutoff, Velocity
1290 persson 791 curve and Velocity range. The keyboard tracking now scales
1291     cutoff frequency instead of resonance.
1292 persson 877 - added support for gig parameter Resonance.
1293 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1294 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1295     which can be overridden with --enable-global-attenuation
1296 persson 783 - EG fixes: made the length of "attack hold" stage more
1297     accurate. Release stage can now start before attack stage
1298 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1299     time now has a minimal value to prevent clicks.
1300 persson 799 - fixed pitch changes larger than one octave
1301 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1302     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1303     all modes can be altered via standard GM messages, that is CC5 for
1304     altering portamento time, CC65 for enabling / disabling portamento
1305     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1306 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1307     parameter) and crossfade
1308 persson 831 - added support for the "attenuation controller threshold" gig
1309     parameter
1310 persson 832 - added smoothing of volume changes caused by control change
1311     messages
1312 persson 865 - sample loop parameters are now taken from the DimensionRegion
1313     instead of the wave chunk
1314     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1315     not equal to a power of two
1316 persson 877 - reimplementation of the filter algorithm. The new filter is more
1317     accurate and supports all gig filter types, including bandreject
1318     and lowpass turbo.
1319 persson 903 - real support for 24 bit samples - samples are not truncated to
1320     16 bits anymore
1321     - support for aftertouch (channel pressure, not polyphonic
1322     aftertouch)
1323 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1324     amplifying from 0)
1325 persson 696
1326 schoenebeck 711 * LSCP server:
1327     - fixed application exit on broken pipe error (fixes bug #20)
1328 iliev 793 - fixed the notification messages delay due to lack of
1329     network activity (fixes bug #26)
1330 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1331     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1332 schoenebeck 711
1333 schoenebeck 838 * audio driver:
1334     - added aRts audio output driver (by no means RT safe)
1335    
1336 schoenebeck 775 * MIDI driver:
1337     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1338     messages several times instead of once
1339 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1340     for events (i.e. for offline rendering based MIDI drivers)
1341 persson 922 - added checks for bad MIDI data
1342 schoenebeck 775
1343 schoenebeck 900 * linuxsampler application:
1344     - show available sampler engine types on startup
1345    
1346 schoenebeck 705 * general changes:
1347     - support for muting sampler channels and solo mode of the same, two new
1348     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1349     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1350     introduced for this, the behavior is the same like on a mixer console
1351 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1352     --enable-process-muted-channels which can be used to enable the
1353     processing of muted channels.
1354 iliev 777 - support for sostenuto pedal
1355 iliev 779 - support for monitoring the total number of active voices
1356 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1357     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1358 persson 835 - fixed some memory management errors
1359 persson 841 - fixed some concurrency problems that could lead to crashes when
1360     LSCP commands were executed
1361 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1362     sampler channel (fixes bug #36)
1363 schoenebeck 705
1364 schoenebeck 692 Version 0.3.3 (15 July 2005)
1365 schoenebeck 686
1366     * packaging changes:
1367     - fixed compilation with gcc 4.0
1368    
1369 schoenebeck 687 * Gigasampler format engine:
1370     - LFO preprocessing was performed even though the respective LFO was
1371     disabled by the instrument patch (minor efficiency fix)
1372 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1373     for volume ramp downs in the same fragment (needed for current voice
1374     stealing implementation) then simply inform the user with a warning
1375     about possible click sounds and reduce the volume ramp down
1376     appropriately instead of cancelling the audio device connection
1377 schoenebeck 687
1378 schoenebeck 677 Version 0.3.2 (24 June 2005)
1379 schoenebeck 609
1380     * packaging changes:
1381     - updated autotools build files to compile on OS X
1382     (conditional compilation of CoreMIDI and MidiShare drivers)
1383 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1384     './configure --disable-asm' (definitely not recommended)
1385 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1386     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1387     (due to 'dist-bzip2' automake option)
1388 schoenebeck 649
1389     * Gigasampler format engine:
1390     - support for the gig parameters for "release velocity response" curves
1391     - fine tuning of the EGADSR envelope
1392     - volume of release triggered samples now depends on note-on velocity,
1393     note length and gig parameter "release trigger decay" instead of
1394     note-off velocity.
1395 schoenebeck 663 - revised voice stealing
1396     (fixes crash and endless loop caused by voice stealing)
1397 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1398 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1399     instead of when the respective voice is actually launched
1400     (fixes undefined behavior if stolen voices belonged to a key group -
1401     this case was followed by a "killed voice survived" error message)
1402 schoenebeck 669 - fixed minor issue with null/silence samples
1403     (those stole voices even though they don't need a voice at all which
1404     resulted in "voice stealing didn't work out" messages)
1405 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1406     instrument or audio output device change
1407 schoenebeck 654
1408 schoenebeck 620 * LSCP server:
1409 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1410 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1411 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1412 schoenebeck 609
1413 schoenebeck 668 * linuxsampler application:
1414     - added command line parameters --lscp-addr and --lscp-port to override
1415     default IP address and port of LSCP server
1416    
1417 schoenebeck 579 Version 0.3.1 (24 May 2005)
1418    
1419     * initial release
