* NKSP: Implemented built-in script function "change_sustain()".
* Bumped version (2.0.0.svn72).

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 3072
20 persson 2837 * general changes:
21     - fixed printf type errors (mostly in debug messages)
22 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
23 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
24     allowing to sort data efficiently in real-time safe manner.
25     - RTList class: added methods for moving/inserting elements to arbitrary
26     position within a list.
27     - RTList class: added method fromPtr() for creating an Iterator object from
28     a raw element pointer.
29     - Attempt to partly fix resetting engine channels vs. resetting engine, an
30     overall cleanup of the Reset*(), ConnectAudioDevice(),
31     DisconnectAudioDevice() API methods would still be desirable though,
32     because the current situation is still inconsistent and error prone.
33 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
34     being directly assigned to a keyboard key. This allows more fine graded
35     processing of voices, which is i.e. required for certain instrument
36     script features.
37 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
38     (CC #64) events.
39     - Fix: Release trigger voices can now also distinguish correctly between
40     note-off and sustain pedal up events.
41 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
42     (while slow rate of crossfade smoother is preserved) to allow quick
43     volume and pan changes by instrument scripts for instance.
44 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
45     properly and thus were ignored for certain uses.
46 schoenebeck 3018 - Added new C++ API method
47     VirtualMidiDevice::SendChannelPressureToSampler().
48 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
49     sub threads is 16-byte aligned
50 schoenebeck 3054 - fixed numerous compiler warnings
51 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
52 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
53     fixes potential undefined behavior.
54 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
55     have a valid sample mapped (fixes bug #252).
56     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
57 persson 2837
58 schoenebeck 2866 * packaging changes:
59     - removed unnecessary dependency to libuuid
60     (originated by libgig's usage of it)
61 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
62     auto detect whether it (sh/c)ould output its messages in color.
63 schoenebeck 2866
64 schoenebeck 2871 * Real-time instrument scripts:
65     - Implemented scheduler for delayed MIDI events and for suspended scripts.
66     - Built-in script function "wait()": implemented support for function's
67     "duration-us" argument, thus scripts using this function are now
68     correctly resumed after the requested amount of microseconds.
69     - Built-in script function "play_note()": implemented support for
70     function's "duration-us" argument, thus notes triggered with this
71     argument are now correctly released after the requested amount of
72     microseconds.
73     - Fix: script events were not cleared when engine channel was reset,
74     potentially causing undefined behavior.
75     - Fixed crash which happened when trying to reference an undeclared
76     variable.
77 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
78     special value -1 for "duration-us" argument, which will cause the
79     triggered note to be released once the original note was released.
80 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
81     - Added new API method ScriptVM::syntaxHighlighting() which provides
82     a convenient syntax highlighting backend for external instrument
83     script editor applications.
84 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
85     - Extended parser issues to provide not only first line and first
86     column, but also last line and last column of issue (thus marking
87     the precise span of the issue within the source code).
88 schoenebeck 2902 - Reload script automatically after being modified by an instrument
89     editor.
90 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
91     like "on note end on".
92 schoenebeck 2931 - Implemented built-in script function "change_vol()".
93     - Implemented built-in script function "change_tune()".
94     - Implemented built-in script function "change_pan()".

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

132     - Implemented built-in script function "change_decay()".
133     - Implemented built-in script function "change_release()".
134 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
135     synthesis parameter changes immediately in case the respective note
136     was triggered at the same time, instead of scheduling the parameter
137     change, especially because it would cause some parameter types's
138     changes either to be ramped (i.e. change_vol()) or other types even
139     to have not effect at all (i.e. change_attack()).
140 schoenebeck 2965 - Implemented built-in script function "sh_left()".
141     - Implemented built-in script function "sh_right()".
142 schoenebeck 2970 - Implemented built-in script function "min()".
143     - Implemented built-in script function "max()".
144 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
145     was loaded.
146     - NKSP built-in wait() script function: abort script execution if
147     a negative or zero wait time was passed as argument (since this is
148     a common indication of a bug either of the script or even of the
149     engine, which could lead to RT instability or even worse).
150 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
151     threatening scripts.
152 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
153 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
154     initializer list to an array variable.
155 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".

166     script functions "change_vol()", "change_tune()", "change_pan()",
167     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
168     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
169     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
170 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
171     of its possible parameter selections.
172     - Added built-in script function "set_event_par()" and implemented some
173     of its possible parameter selections.
174 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
175 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
176 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with

178 schoenebeck 3214 - Implemented built-in script function "change_velo()".
179     - Implemented built-in script function "change_note()".
180 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
181     intuitive behavior if used in combination with "change_vol_time()" or
182     "change_tune_time()" respectively: now tuning/volume changes are only
183     assigned (without delay) immediately to a new note if the respective
184     timing function has not been called before, otherwise the volume/tuning
185     changes are automatically faded (before, only the event's time stamp was
186     relevant).
187 schoenebeck 3221 - Implemented built-in script function "array_equal()".
188     - Implemented built-in script function "search()".
189     - Implemented built-in script function "sort()".

192     available for gig format engine).
193 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
194     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
195     - Implemented built-in script function "change_vol_curve()".
196     - Implemented built-in script function "change_tune_curve()".
197 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
198     offset with argument 3, where special value -1 means to use the regular
199     sample offset as defined by the instrument file.
200 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
201     - Built-in variable $EVENT_NOTE is now a read-only variable.
202     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
203     - built-in "play_note()" function now accepts -2 for its fourth argument
204     (note duration) which means the life time of the note shall be sticked
205     to the requested note number of argument 1.
206     - Fix: built-in "play_note()" function now returns 0 as result value if
207     -1 was passed for its fourth argument (note duration) and the respective
208     parent note is already gone.
209 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
210 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

215     code blocks.
216 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
217     another script handler by passing its callback ID.
218 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
219     "init" event handlers.
220 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
221     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
222     to retrieve all code blocks filtered out by the preprocessor.
223 schoenebeck 3293 - Added built-in script function "fork()".
224     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
225     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
226     - Fixed potential crash when accessing dynamic built-in array variables.
227 schoenebeck 3296 - Added built-in script function "callback_status()".
228     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
229     - Added built-in constant $CALLBACK_STATUS_QUEUE.
230     - Added built-in constant $CALLBACK_STATUS_RUNNING.
231 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
232     "change_decay()" and "change_release()" to i.e. allow passing 2000000
233     for doubling the respective time.
234 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
235     to a lexer start condition stack underrun.
236     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
237     USE_CODE_IF_NOT() preprocessor statements.
238 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
239     can be set to disable all subsequent built-in "message()" function calls
240     on preprocessor level.
241 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
242 schoenebeck 2871
243 schoenebeck 3050 * Instruments DB:
244     - Fixed memory access bug of general DB access code which lead to
245     undefined behavior.
246 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
247     - The instrument DB path of linuxsampler's --create-instruments-db argument
248     is now optional, if it is missing, then a default location is used.
249 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
250     - Added support for scanning Sound Font (.sf2) files.
251 schoenebeck 3101 - Fixed undefined DB transaction behavior.

292 persson 2382
293 persson 2086 * general changes:
294 iliev 2012 - Refactoring: moved the independent code from
295     the Gigasampler format engine to base classes
296 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
297     respective profiling code is currently broken
298 schoenebeck 2053 - Introduced support for optional environment variable
299     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
300     where the sampler shall look for instrument editor plugins
301     (patch by Luis Garrido, slightly modified).
302 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
303     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
304     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
305     note (in this implementation of the sampler its simply hard routed to
306     the 1st effect send of the sampler channel, no matter what the actual
307     effect type is)
308     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
309     note (in this implementation of the sampler its simply hard routed to
310     the 2nd effect send of the sampler channel, no matter what the actual
311     effect type is)
312 schoenebeck 2124 - implemented support for internal LADSPA effects
313 schoenebeck 2140 - raised limit of program change queue from 100 to 512
314     (as suggested by Alex Stone)
315 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
316 iliev 2296 - experimental support for per voice equalization
317 iliev 2306 - added command line option --exec-after-init
318 schoenebeck 2330 - Introduced new C++ API method:
319     EngineChannel::InstrumentFileName(int index)
320     allowing to retrieve the whole list of files used for the loaded
321     instrument on an engine channel (a.k.a. part). Some GigaStudio
322     instruments for example are splitted over several files like
323     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
324 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
325     - Added new C++ API method Sampler::GetGlobalMaxStreams().
326     - Added new C++ API method Sampler::SetGlobalMaxVoices().
327     - Added new C++ API method Sampler::SetGlobalMaxStreams().
328 schoenebeck 2377 - Various "const" and "restrict" optimizations.
329 persson 2382 - all engines: add pan CC value to instrument pan parameter before
330     applying panning, instead of using two separate pan functions in
331     series (#182)
332 persson 2427 - added a lock guard class for exception safe mutex handling and
333     used it everywhere appropriate
334 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
335     - Exposed scale tuning to C++ API (along to the already existing standard
336     SysEx way).
337 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
338     and broken for ppc64. (Seq_cst loads and stores are actually not
339     used in LS, so the bug wasn't noticable.)
340     - lsatomic.h: added ARMv7 support
341 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
342     added various new C++ methods for this new feature / design change, old
343     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
344     as deprecated but are still there and should provide full behavior
345     backward compatibility).
346     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
347     unsafe and caused compilation error with clang 2.x).
348 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
349 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
350     sampler from the command line by providing LSCP aware features.
351 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
352     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
353     - VirtualMidiDevice: Added support for pitch bend.
354 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
355     polyphonic key pressure events (so far polyphonic pressure was not
356     supported at all, and channel pressure was rerouted as CC128 but not
357     used so far).
358 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
359     code is shared by all sampler engine implemementations, however only the
360     gig file format currently provides support for storing instrument scripts
361     (as LinuxSampler extension to the original GigaStudio 4 format).
362 iliev 2012
363 persson 2043 * Gigasampler format engine:
364     - implemented the "round robin keyboard" dimension
365     - fixed round robin and random dimensions for cases when number of
366     dimension zones is not a power of two

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

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

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

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

871 iliev 1829 - added (experimental) CoreAudio driver
872 persson 1888 - applied old fixes to the ASIO driver that were included in the
873     previous binary release but accidentally never committed to CVS
874     (fixes #117)
875 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

890     exception when getting parameters from a disconnected device
891 schoenebeck 1599
892 persson 1651 * MIDI driver:
893     - added JACK MIDI driver
894 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
895     want to (mis)use it for some purpose ("fixed" in all current MIDI
896     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
897 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,

912     instrument database compilable
913 schoenebeck 1930 - added instrument database support on Windows
914     works with both standalone mode and VST plugin.
915     the instruments DB file is located in
916     %USERPROFILE%\.linuxsampler\instruments.db which allows different
917     databases for each windows user
918     if no DB is present it automatically creates the .linuxsampler subdir
919     and then creates an empty DB
920 persson 1943 - fixed recursive import, which was broken on Windows
921 iliev 1603
922 persson 1644 * Gigasampler format engine:
923     - fixed a memory leak that could happen when a channel was deleted
924     while notes were playing
925 persson 1646 - made it possible to load an instrument even if the audio thread
926     isn't running
927 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
928     enough for piano gigs with pedal noise samples
929 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
930     respective FX send MIDI controller was used
931 schoenebeck 1724 - added support for GM global device volume SysEx message
932 schoenebeck 1762 (can be selected at compile time to either apply globally to the
933     whole sampler [default] or only to the sampler channels that are
934     connected to the respective MIDI input port the SysEx message arrived
935     on)
936 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
937     sometimes wrongly killed in the same buffer, causing no sound to
938     be played
939 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
940     which is usally used to switch a part between chromatic sounds and
941     drumkit sounds (as opposed to their common default setting of MIDI
942     part 10 being a drumkit part and all other ones chromatic parts), in
943     LS however one can switch between the first 16 MIDI instrument maps
944     defined for the sampler
945 persson 1764 - made it possible to create multiple sample channels even if the
946     audio thread isn't running
947 persson 1844 - fixed crash when removing channel with active voices (#116)
948 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
949     un-cache the respective sample if it's really not used by any
950     sampler engine anymore
951     - re-cache samples in case they were changed by an instrument editor,
952     e.g. when a sample was added while playing (#82)
953 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
954     same time stamp as the voice's note-on event and occured both in the
955     same audio fragment cycle (fixes bug #112)
956 persson 1858 - added support for the "fine tune" and "pitch bend range"
957     instrument-level gig parameters
958     - fixed minor artifacts in pitch bend handling
959 schoenebeck 1860 - added support for GS Reset SysEx message
960 persson 1862 - allow gig files to use unlimited downward pitch shifting
961     - added a limit check for upward pitch shifting
962 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
963     note was silent
964 persson 1923 - fixed crash happening when a pitch bend event arrived at the
965     same time a new instrument was loading
966 persson 1644
967 schoenebeck 1687 * LSCP server:
968     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
969     react on MIDI data arriving on certain sampler channels (so far only
970     Note-On and Note-Off events are sent via this LSCP event)
971 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
972     react on MIDI data arriving on certain MIDI input devices (so far only
973     Note-On and Note-Off events are sent via this LSCP event)
974 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
975     SET DB_INSTRUMENT FILE_PATH

977     frontends to send MIDI messages to specific sampler channel
978     - added two additional fields to GET FILE INSTRUMENT INFO command -
979     KEY_BINDINGS and KEYSWITCH_BINDINGS
980 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
981     was incorrect
982 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
983 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
984     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
985     be triggered respectively
986     - added new LSCP command "SET STREAMS" to globally alter the maximum
987     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
988     which will be triggered respectively
989 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
990     a gigedit file dialog is opened)
991 iliev 1848 - close all connections when LSCPServer is deleted
992 iliev 1882 - hard close of all sockets on exit

1011 iliev 1847 - fixed crash when changing the audio output device of a sampler
1012     channel with loaded instrument and start playing notes
1013 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1014 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

1033     - bugfix: the thread used by an editor plugin didn't die when the
1034     editor closed
1035 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1036     out all the space. operator--() did not apply size_mask after
1037     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1038     order to avoid problems with the _NonVolatileReader functions.
1039     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1040     GetWriteSpace(). Since this function is currently only used in
1041     the stream's qsort() compare function, it didn't trigger any
1042     bugs.
1043     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1044     24bit mode too. Faster method to read 24bit words on little

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