File size: 74222 byte(s)
* NKSP: Print a time stamp along to each call of built-in function
  "message()".
* ScriptVM API: Added VMParserContext::preprocessorComments() which
  allows to retrieve all code blocks filtered out by the
  preprocessor.
* Bumped version (2.0.0.svn63).

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 2856
11 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
12 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13     cutoff settings.
14    
15 persson 2837 * general changes:
16     - fixed printf type errors (mostly in debug messages)
17 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
18 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19     allowing to sort data efficiently in real-time safe manner.
20     - RTList class: added methods for moving/inserting elements to arbitrary
21     position within a list.
22     - RTList class: added method fromPtr() for creating an Iterator object from
23     a raw element pointer.
24     - Attempt to partly fix resetting engine channels vs. resetting engine, an
25     overall cleanup of the Reset*(), ConnectAudioDevice(),
26     DisconnectAudioDevice() API methods would still be desirable though,
27     because the current situation is still inconsistent and error prone.
28 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
29     being directly assigned to a keyboard key. This allows more fine graded
30     processing of voices, which is i.e. required for certain instrument
31     script features.
32 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
33     (CC #64) events.
34     - Fix: Release trigger voices can now also distinguish correctly between
35     note-off and sustain pedal up events.
36 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
37     (while slow rate of crossfade smoother is preserved) to allow quick
38     volume and pan changes by instrument scripts for instance.
39 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40     properly and thus were ignored for certain uses.
41 schoenebeck 3018 - Added new C++ API method
42     VirtualMidiDevice::SendChannelPressureToSampler().
43 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
44     sub threads is 16-byte aligned
45 schoenebeck 3054 - fixed numerous compiler warnings
46 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47 persson 2837
48 schoenebeck 2866 * packaging changes:
49     - removed unnecessary dependency to libuuid
50     (originated by libgig's usage of it)
51 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52     auto detect whether it (sh/c)ould output its messages in color.
53 schoenebeck 2866
54 schoenebeck 2871 * Real-time instrument scripts:
55     - Implemented scheduler for delayed MIDI events and for suspended scripts.
56     - Built-in script function "wait()": implemented support for function's
57     "duration-us" argument, thus scripts using this function are now
58     correctly resumed after the requested amount of microseconds.
59     - Built-in script function "play_note()": implemented support for
60     function's "duration-us" argument, thus notes triggered with this
61     argument are now correctly released after the requested amount of
62     microseconds.
63     - Fix: script events were not cleared when engine channel was reset,
64     potentially causing undefined behavior.
65     - Fixed crash which happened when trying to reference an undeclared
66     variable.
67 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
68     special value -1 for "duration-us" argument, which will cause the
69     triggered note to be released once the original note was released.
70 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
71     - Added new API method ScriptVM::syntaxHighlighting() which provides
72     a convenient syntax highlighting backend for external instrument
73     script editor applications.
74 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
75     - Extended parser issues to provide not only first line and first
76     column, but also last line and last column of issue (thus marking
77     the precise span of the issue within the source code).
78 schoenebeck 2902 - Reload script automatically after being modified by an instrument
79     editor.
80 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
81     like "on note end on".
82 schoenebeck 2931 - Implemented built-in script function "change_vol()".
83     - Implemented built-in script function "change_tune()".
84     - Implemented built-in script function "change_pan()".
85 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
86     - Implemented built-in script function "change_reso()".
87     - Implemented built-in script function "event_status()".
88     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90     "event_status()" function.
91     - NKSP language: Added support for bitwise operators ".or.", ".and."
92     and ".not.".
93     - NKSP language scanner: Fixed IDs matching to require at least one
94     character (i.e. when matching function names or variable names).
95     - NKSP language scanner: disabled unusued rules.
96 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
97     be distinguished engine internally from "real" MIDI note on/off
98     events in order to avoid misbehaviors like hanging notes.
99 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
100     - Implemented built-in script variable "$NKSP_REAL_TIMER".
101     - Implemented built-in script variable "$NKSP_PERF_TIMER".
102     - Implemented built-in script variable "$ENGINE_UPTIME".
103 schoenebeck 2945 - Implemented built-in script function "inc()".
104     - Implemented built-in script function "dec()".
105     - NKSP language fix: division expressions were evaluated too often.
106     - NKSP language fix: string concatenation operator was right
107     associative instead of left (to right).
108 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
109     (i.e. "if end if").
110 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
111     - Implemented built-in script variable "$NI_CALLBACK_ID".
112     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114     - Added support for read-only built-in variables (respectively
115     handled by the script parser).
116     - Added built-in script constant "$NI_CB_TYPE_INIT".
117     - Added built-in script constant "$NI_CB_TYPE_NOTE".
118     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

121 schoenebeck 2953 - Implemented built-in script function "change_attack()".
122     - Implemented built-in script function "change_decay()".
123     - Implemented built-in script function "change_release()".
124 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
125     synthesis parameter changes immediately in case the respective note
126     was triggered at the same time, instead of scheduling the parameter
127     change, especially because it would cause some parameter types's
128     changes either to be ramped (i.e. change_vol()) or other types even
129     to have not effect at all (i.e. change_attack()).
130 schoenebeck 2965 - Implemented built-in script function "sh_left()".
131     - Implemented built-in script function "sh_right()".
132 schoenebeck 2970 - Implemented built-in script function "min()".
133     - Implemented built-in script function "max()".
134 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
135     was loaded.
136     - NKSP built-in wait() script function: abort script execution if
137     a negative or zero wait time was passed as argument (since this is
138     a common indication of a bug either of the script or even of the
139     engine, which could lead to RT instability or even worse).
140 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
141     threatening scripts.
142 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
143 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
144     initializer list to an array variable.
145 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
146 schoenebeck 3076 - Implemented built-in script function "in_range()".

150     - Implemented built-in script function "change_pitch_lfo_freq()".
151 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
152     - Implemented built-in script function "change_tune_time()".
153     - Implemented built-in script function "fade_in()".
154     - Implemented built-in script function "fade_out()".
155     - Fixed acceptance of wrong data type of parameters passed to built-in
156     script functions "change_vol()", "change_tune()", "change_pan()",
157     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
161     of its possible parameter selections.
162     - Added built-in script function "set_event_par()" and implemented some
163     of its possible parameter selections.
164 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
165 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
166 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
167     built-in function "ignore_controller()".
168 schoenebeck 3214 - Implemented built-in script function "change_velo()".
169     - Implemented built-in script function "change_note()".
170 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171     intuitive behavior if used in combination with "change_vol_time()" or
172     "change_tune_time()" respectively: now tuning/volume changes are only
173     assigned (without delay) immediately to a new note if the respective
174     timing function has not been called before, otherwise the volume/tuning
175     changes are automatically faded (before, only the event's time stamp was
176     relevant).
177 schoenebeck 3221 - Implemented built-in script function "array_equal()".
178     - Implemented built-in script function "search()".
179     - Implemented built-in script function "sort()".
180     - NKSP Fix: Never suspend "init" event handlers.
181 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
182     available for gig format engine).
183 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
184     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
185     - Implemented built-in script function "change_vol_curve()".
186     - Implemented built-in script function "change_tune_curve()".
187 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
188     offset with argument 3, where special value -1 means to use the regular
189     sample offset as defined by the instrument file.
190 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
191     - Built-in variable $EVENT_NOTE is now a read-only variable.
192     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
193     - built-in "play_note()" function now accepts -2 for its fourth argument
194     (note duration) which means the life time of the note shall be sticked
195     to the requested note number of argument 1.
196     - Fix: built-in "play_note()" function now returns 0 as result value if
197     -1 was passed for its fourth argument (note duration) and the respective
198     parent note is already gone.
199 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
200 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
201     - NKSP language: Raise parser warning if array variable is accessed with

205     code blocks.
206 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
207     another script handler by passing its callback ID.
208 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
209     "init" event handlers.
210 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
211     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
212     to retrieve all code blocks filtered out by the preprocessor.
213 schoenebeck 2871
214 schoenebeck 3050 * Instruments DB:
215     - Fixed memory access bug of general DB access code which lead to
216     undefined behavior.
217 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
218     - The instrument DB path of linuxsampler's --create-instruments-db argument
219     is now optional, if it is missing, then a default location is used.
220 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
221     - Added support for scanning Sound Font (.sf2) files.
222 schoenebeck 3101 - Fixed undefined DB transaction behavior.

232     - removed empty directories left from the cvs to svn migration
233 persson 2185 - fixed compilation with gcc 4.6.1
234 persson 2203 - another "make dist" fix, for the LV2 plugin
235 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
236 persson 2197 - minor Makefile fix for building lscpparser when build and source
237     directories are separate
238 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

262     in order to get rid of warnings from automake 1.14
263 persson 2382
264 persson 2086 * general changes:
265 iliev 2012 - Refactoring: moved the independent code from
266     the Gigasampler format engine to base classes
267 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
268     respective profiling code is currently broken
269 schoenebeck 2053 - Introduced support for optional environment variable
270     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
271     where the sampler shall look for instrument editor plugins
272     (patch by Luis Garrido, slightly modified).
273 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
274     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
275     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
276     note (in this implementation of the sampler its simply hard routed to
277     the 1st effect send of the sampler channel, no matter what the actual
278     effect type is)
279     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
280     note (in this implementation of the sampler its simply hard routed to
281     the 2nd effect send of the sampler channel, no matter what the actual
282     effect type is)
283 schoenebeck 2124 - implemented support for internal LADSPA effects
284 schoenebeck 2140 - raised limit of program change queue from 100 to 512
285     (as suggested by Alex Stone)

287 iliev 2296 - experimental support for per voice equalization
288 iliev 2306 - added command line option --exec-after-init
289 schoenebeck 2330 - Introduced new C++ API method:
290     EngineChannel::InstrumentFileName(int index)
291     allowing to retrieve the whole list of files used for the loaded
292     instrument on an engine channel (a.k.a. part). Some GigaStudio
293     instruments for example are splitted over several files like
294     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
295 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
296     - Added new C++ API method Sampler::GetGlobalMaxStreams().
297     - Added new C++ API method Sampler::SetGlobalMaxVoices().
298     - Added new C++ API method Sampler::SetGlobalMaxStreams().
299 schoenebeck 2377 - Various "const" and "restrict" optimizations.
300 persson 2382 - all engines: add pan CC value to instrument pan parameter before
301     applying panning, instead of using two separate pan functions in
302     series (#182)
303 persson 2427 - added a lock guard class for exception safe mutex handling and
304     used it everywhere appropriate
305 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
306     - Exposed scale tuning to C++ API (along to the already existing standard
307     SysEx way).
308 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
309     and broken for ppc64. (Seq_cst loads and stores are actually not
310     used in LS, so the bug wasn't noticable.)
311     - lsatomic.h: added ARMv7 support
312 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
313     added various new C++ methods for this new feature / design change, old
314     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
315     as deprecated but are still there and should provide full behavior
316     backward compatibility).
317     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
318     unsafe and caused compilation error with clang 2.x).
319 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
320 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
321     sampler from the command line by providing LSCP aware features.
322 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
323     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
324     - VirtualMidiDevice: Added support for pitch bend.
325 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
326     polyphonic key pressure events (so far polyphonic pressure was not
327     supported at all, and channel pressure was rerouted as CC128 but not
328     used so far).
329 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
330     code is shared by all sampler engine implemementations, however only the
331     gig file format currently provides support for storing instrument scripts
332     (as LinuxSampler extension to the original GigaStudio 4 format).
333 iliev 2012
334 persson 2043 * Gigasampler format engine:
335     - implemented the "round robin keyboard" dimension
336     - fixed round robin and random dimensions for cases when number of
337     dimension zones is not a power of two
338     - made round robin use a counter for each region instead of each
339     key
340 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
341     - bugfix: filter keyboard tracking was broken
342     - filter performance fix (an unnecessary copy was made of the
343     filter parameters in each sub fragment)
344     - handle special case when pan parameter in gig file has max or
345     min value
346 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
347     doesn't sound naturally with a drumkit
348 persson 2408 - fixed EG1 modulation when attack or release is zero
349 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
350 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
351     conditions (see also previous commit on libgig).
352 persson 2673 - fixed behaviour of filter LFO
353 persson 2043
354 schoenebeck 2047 * SFZ format engine:
355 iliev 2012 - Initial implementation (not usable yet)
356 persson 2055 - added support for v2 multiple stage envelope generators
357     - added a fine-tuned v1 envelope generator instead of using the
358     one from the gig engine
359 persson 2058 - fixed memory leak and memory handling errors
360 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
361 persson 2058 - allow non-numerical key values ("C#4" for example)
362     - "key" opcode now sets pitch_keycenter too
363     - fixed error when unloading instrument with same sample used by
364     multiple regions
365     - added some opcode aliases, like loopmode for loop_mode, to be
366     more compatible
367 persson 2061 - added support for trigger=release and rt_decay
368 persson 2063 - added support for off_mode=normal
369 persson 2072 - added support for random, seq_position, seq_length and volume

718 persson 2127 - fixed crash when deleting a sampler channel or changing engine
719     type while an instrument load was in progress
720 persson 2162 - bugfix: playing a note while changing the instrument could cause
721     a crash, or give "Handing back unknown region" error messages
722 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
723     refresh) could cause instruments to be unloaded

725     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
726 persson 2185 - Mac OS X: fixed hanging threads

730     after MIDI/audio device creation failure
731 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
732     instruments were uselessly precached with zero samples, however it still
733     took the full preloading time and on 1st program change the respective
734     instrument was completely reloaded again.
735 persson 2277 - fixed handling of rapid bank select and program change messages
736     sent to the same sampler channel (patch from the Open Octave
737     project, slightly adjusted)

755 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
756     crashes and noise on such transitions).
757 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
758     (fixes #208)
759 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
760     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
761     practically irrelevant, however it caused problems with the new LSCP
762     shell's auto completion feature).
763 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
764     after each other (fixes #231).

814 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
815     be switched on by command line option "--stacktrace" (the automatic
816     stacktrace mechanism seems to be broken on most systems at the moment)
817 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
818     a pointer to the launched InstrumentEditor object
819 schoenebeck 1876 - added optional 3rd party user data parameter for following
820     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

841 persson 1748 jack_client_new
842 iliev 1829 - added (experimental) CoreAudio driver
843 persson 1888 - applied old fixes to the ASIO driver that were included in the
844     previous binary release but accidentally never committed to CVS
845     (fixes #117)
846 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
847     win64)

861     exception when getting parameters from a disconnected device
862 schoenebeck 1599
863 persson 1651 * MIDI driver:
864     - added JACK MIDI driver
865 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
866     want to (mis)use it for some purpose ("fixed" in all current MIDI
867     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
868 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
869 persson 1887 CoreMidi or AU

882 persson 1908 - work-around for missing fnmatch function on Windows to make
883     instrument database compilable
884 schoenebeck 1930 - added instrument database support on Windows
885     works with both standalone mode and VST plugin.
886     the instruments DB file is located in
887     %USERPROFILE%\.linuxsampler\instruments.db which allows different
888     databases for each windows user
889     if no DB is present it automatically creates the .linuxsampler subdir
890     and then creates an empty DB
891 persson 1943 - fixed recursive import, which was broken on Windows
892 iliev 1603
893 persson 1644 * Gigasampler format engine:
894     - fixed a memory leak that could happen when a channel was deleted
895     while notes were playing
896 persson 1646 - made it possible to load an instrument even if the audio thread
897     isn't running
898 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
899     enough for piano gigs with pedal noise samples
900 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
901     respective FX send MIDI controller was used
902 schoenebeck 1724 - added support for GM global device volume SysEx message
903 schoenebeck 1762 (can be selected at compile time to either apply globally to the
904     whole sampler [default] or only to the sampler channels that are
905     connected to the respective MIDI input port the SysEx message arrived
906     on)
907 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
908     sometimes wrongly killed in the same buffer, causing no sound to
909     be played
910 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
911     which is usally used to switch a part between chromatic sounds and
912     drumkit sounds (as opposed to their common default setting of MIDI
913     part 10 being a drumkit part and all other ones chromatic parts), in
914     LS however one can switch between the first 16 MIDI instrument maps
915     defined for the sampler
916 persson 1764 - made it possible to create multiple sample channels even if the
917     audio thread isn't running
918 persson 1844 - fixed crash when removing channel with active voices (#116)
919 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
920     un-cache the respective sample if it's really not used by any
921     sampler engine anymore
922     - re-cache samples in case they were changed by an instrument editor,
923     e.g. when a sample was added while playing (#82)
924 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
925     same time stamp as the voice's note-on event and occured both in the
926     same audio fragment cycle (fixes bug #112)
927 persson 1858 - added support for the "fine tune" and "pitch bend range"
928     instrument-level gig parameters
929     - fixed minor artifacts in pitch bend handling
930 schoenebeck 1860 - added support for GS Reset SysEx message
931 persson 1862 - allow gig files to use unlimited downward pitch shifting
932     - added a limit check for upward pitch shifting
933 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
934     note was silent
935 persson 1923 - fixed crash happening when a pitch bend event arrived at the
936     same time a new instrument was loading
937 persson 1644
938 schoenebeck 1687 * LSCP server:
939     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
940     react on MIDI data arriving on certain sampler channels (so far only
941     Note-On and Note-Off events are sent via this LSCP event)
942 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
943     react on MIDI data arriving on certain MIDI input devices (so far only
944     Note-On and Note-Off events are sent via this LSCP event)
945 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
946     SET DB_INSTRUMENT FILE_PATH
947 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
948     frontends to send MIDI messages to specific sampler channel
949     - added two additional fields to GET FILE INSTRUMENT INFO command -
950     KEY_BINDINGS and KEYSWITCH_BINDINGS
951 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
952     was incorrect
953 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
954 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
955     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
956     be triggered respectively
957     - added new LSCP command "SET STREAMS" to globally alter the maximum
958     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
959     which will be triggered respectively
960 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
961     a gigedit file dialog is opened)
962 iliev 1848 - close all connections when LSCPServer is deleted
963 iliev 1882 - hard close of all sockets on exit
964 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
965     driver
966 schoenebeck 1687

977     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
978     GET MIDI_INPUT_DRIVER INFO
979     GET MIDI_INPUT_DRIVER_PARAMETER INFO

981 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
982 iliev 1847 - fixed crash when changing the audio output device of a sampler
983     channel with loaded instrument and start playing notes
984 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
985 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
986     PowerPC, which probably could cause crashes on that platform
987 persson 1889 - fixed a memory management error which could cause a crash when a
988     plugin was unloaded
989 persson 1896 - bugfix: two private structs had the same name, which could cause

991 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
992     Windows
993 iliev 1761

1004     - bugfix: the thread used by an editor plugin didn't die when the
1005     editor closed
1006 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1007     out all the space. operator--() did not apply size_mask after
1008     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1009     order to avoid problems with the _NonVolatileReader functions.
1010     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1011     GetWriteSpace(). Since this function is currently only used in
1012     the stream's qsort() compare function, it didn't trigger any
1013     bugs.
1014     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1015     24bit mode too. Faster method to read 24bit words on little
1016     endian machines (x86): replaced 3 byte reads + shifts with a 1
1017     unaligned 32bit read and shift
1018     - experimental support for MS Windows (MIDI input via MME, AUDIO
1019     output via ASIO)
1020     - made handling of SIGINT signal (Ctrl-C) a bit more robust

1027 senoner 1500
1028 senoner 1485 * MIDI driver:
1029 schoenebeck 1495 - added MME Windows MIDI driver
1030 senoner 1485
1031 schoenebeck 1471 * LSCP server:
1032     - added support for Windows style path / filenames, however with
1033     forward slash path separators instead of backslash
1034     (i.e. "C:/foo/bar.gig")
1035 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1036     apostrophes as well
1037 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1038     "LIST FILE INSTRUMENTS <file>" and
1039     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1040     about an arbitrary instrument file on the system where the sampler is
1041     running on
1042 schoenebeck 1471
1043 schoenebeck 1424 Version 0.5.0 (15 October 2007)

1046 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1047     API header files anymore
1048 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1049     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1050 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1051     capable to execute our autoconf environment, thus no need anymore
1052     to maintain the compile time configuration file (osx/version.h) for
1053     OSX manually (patch by Toshi Nagata)
1054 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1055     parameters
1056 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1057     C++ API header files, all implementation internal global definitions
1058     are now in global_private.h
1059     - atomic.h is not exposed to the C++ API anymore
1060     - no need to include config.h anymore for using LS's API header files
1061     - fixed warnings in API doc generation
1062 schoenebeck 1065
1063 schoenebeck 947 * general changes:
1064     - replaced the old, confusing MIDI program change mechanism by a
1065     flexible MIDI instrument mapper which allows to map arbitrary
1066 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1067 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1068     loaded on the respective channel when such MIDI program change
1069     messages arrive, beside that, each entry allows to define a life-time
1070     strategy for the instrument, so the user can define whether the
1071     instrument should i.e. be permanently loaded (to be able to switch
1072     quickly among sounds) or i.e. loaded just on demand when the
1073     respective program change arrives (to safe RAM space), as well as a
1074     global volume factor for each entry, so the user can adjust the volume
1075     dynamic of his mapped instrument collection without having to modify
1076 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1077     MIDI instrument maps and assign each sampler channel individually
1078     a certain map, so that i.e. separation of normal instruments and
1079     drumkits is possible
1080 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1081     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1082 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1083     due to a constant size RingBuffer FIFO which is now replaced by a
1084     dynamic (unlimited) size std::list FIFO
1085 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1086     output channels for being processed by external effect processors
1087     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1088     controllers
1089 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1090 iliev 1130 - Implemented new, improved notification system
1091 schoenebeck 1149 - fixed compilation errors regarding OSX
1092     (patch by Toshi Nagata)
1093 iliev 1161 - implemented instruments database
1094 iliev 1345 - added support for escape sequences to the instruments database
1095 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1096     within the sampler's process (by using instrument editor plugins),
1097     you'll notice the new "Registered instrument editors:" message on
1098 schoenebeck 1407 startup, added a new LSCP command:
1099     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1100 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1101     given sampler channel, the plugin path can be overridden at compile
1102     time with ./configure --enable-plugin-dir=/some/dir
1103 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1104     in the sampler's process to safely edit instruments while playing
1105     without a crash (hopefully) by either suspending single regions
1106     wherever possible or if unavoidable whole engine(s)
1107 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1108     policy and priority on thread level, set a minimum stack size for
1109     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1110     threads simply inherited properties of starting thread instead of
1111     setting their own policy and priority
1112 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1113     main process did not wait for the stack trace process to finish
1114     its output
1115 persson 1248 - fixed some minor memory leaks
1116 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1117     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1118 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1119     register, to avoid relocations in the text segment at runtime)
1120 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1121 schoenebeck 947
1122     * MIDI driver:
1123     - dispatch bank select (MSB and LSB) messages
1124    
1125 schoenebeck 1049 * audio driver:
1126     - the ALSA audio output driver parameters now reflect the correct
1127     parameter value ranges for the respective selected sound card
1128     (patch by Till Wimmer, a bit fixed and extended)
1129    
1130 persson 951 * Gigasampler format engine:
1131     - if a filter is used and EG2 finishes before EG1, let the voice
1132     die when EG2 has finished (this fixes a problem with clicks and
1133     voice starvation for some gigs)
1134 persson 1038 - playback is no longer disabled during instrument loading
1135     - all notes playing on a channel that changes its instrument keep
1136     playing with the old instrument until they get a note off
1137     command
1138 persson 1039 - EG fix: a release value of zero could cause noises or crash
1139 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1140 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1141     above max sustain level, which means that there is a decay phase
1142     even if sustain is 100%
1143 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1144     noises or crashes
1145 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1146 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1147     supplied to the configure script (fixes #46)
1148 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1149     instead of a fix value
1150 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1151     127 (solo mode) only kill voices if the respective mode really
1152     changed
1153 persson 951
1154 schoenebeck 1244 * LSCP server:
1155     - fixed compile time error for old Bison versions
1156     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1157 schoenebeck 1245 - parser now supports extended ASCII character set
1158     (up to ASCII code 255, i.e. includes now umlauts and accents)
1159     - filename arguments in LSCP commands now allow to use escape
1160     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1161     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1162     code value like \xf2) (fixes bug #24)
1163 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1164     least one of their text-based parameters (i.e. name, description):
1165     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1166     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1167     "SET DB_INSTRUMENT_DIRECTORY NAME",
1168     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1169     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1170     "FIND DB_INSTRUMENT_DIRECTORIES"
1171 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1172     occured, the unexpected character and the actually expected, possible
1173     character(s), the latter only if less than 5 possibilities)
1174 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1175     settings
1176 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1177     of strings were treated as being one string containing commas
1178     (fixes #57)
1179 schoenebeck 1244
1180 iliev 959 * Bug fixes:
1181     - fixed crash occurring on certain LSCP scripts (Bug 39)
1182 persson 1038 - another thread safety fix for lscp "load engine" and "set
1183     channel audio output device"
1184 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1185     on a sampler channel with connected MIDI device
1186 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1187     device connected to a sampler channel to number less then or equal
1188     to the index of the port to which the sampler channel is connected.
1189 iliev 1296 - The previous bindings were not been disconnected when altering
1190     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1191     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1192 iliev 1297 - The active stream/voice count statistic was incorrect.
1193 iliev 1298 - notification events were not been sent for some sampler
1194     channel changes
1195 iliev 1305 - added default min and max values to restrict the number of allowed
1196     audio output channels and MIDI input ports
1197 iliev 1306 - the connection to the PCM interface is now closed when destroying
1198     an audio output device
1199 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1200 iliev 959
1201 schoenebeck 1221 * test cases:
1202     - updated and fixed (haven't been touched in a while)
1203    
1204 schoenebeck 937 Version 0.4.0 (24 November 2006)
1205 persson 696
1206 schoenebeck 697 * packaging changes:
1207 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1208     to post-(un)install steps; added devel package for liblinuxsampler;
1209     to linuxsampler.spec (RPM)
1210 schoenebeck 697 - install necessary development header files for allowing 3rd party
1211     applications to link against liblinuxsampler
1212     - liblinuxsampler's API documentation can be generated with 'make docs'
1213     (Doxygen required)
1214 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1215     implementation (currently either an integer math solution or a
1216     di-harmonic approximation), automatic detection can be overriden
1217     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1218     configure script argument though (mandatory for cross-compilation)
1219 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1220     provided some on his own (as CXXFLAGS)
1221 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1222     messages
1223 schoenebeck 852 - added compile time options to allow disabling the various audio and
1224     MIDI drivers
1225 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1226     (patch by Ebrahim Mayat)
1227 schoenebeck 697
1228 persson 696 * Gigasampler format engine:
1229 schoenebeck 738 - extensive synthesis optimization
1230     (reimplementation of EGs and LFO(s), removed synthesis parameter
1231     prerendering and the synthesis parameter matrix in general, splitting
1232     each audio fragment into subfragments now where each subfragment uses
1233 persson 830 constant pitch and filter coefficients. The volume coefficient is
1234     linearly interpolated inside a subfragment, unless
1235     --disable-interpolate-volume is set.)
1236 persson 696 - fine tuning of the EG modulation parameters
1237 persson 729 - improved filter cutoff calculation by adding support for the
1238     following gig parameters: Cutoff freq (used when no cutoff
1239     controller is defined), Control invert, Minimum cutoff, Velocity
1240 persson 791 curve and Velocity range. The keyboard tracking now scales
1241     cutoff frequency instead of resonance.
1242 persson 877 - added support for gig parameter Resonance.
1243 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1244 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1245     which can be overridden with --enable-global-attenuation
1246 persson 783 - EG fixes: made the length of "attack hold" stage more
1247     accurate. Release stage can now start before attack stage
1248 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1249     time now has a minimal value to prevent clicks.
1250 persson 799 - fixed pitch changes larger than one octave
1251 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1252     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1253     all modes can be altered via standard GM messages, that is CC5 for
1254     altering portamento time, CC65 for enabling / disabling portamento
1255     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1256 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1257     parameter) and crossfade
1258 persson 831 - added support for the "attenuation controller threshold" gig
1259     parameter
1260 persson 832 - added smoothing of volume changes caused by control change
1261     messages
1262 persson 865 - sample loop parameters are now taken from the DimensionRegion
1263     instead of the wave chunk
1264     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1265     not equal to a power of two
1266 persson 877 - reimplementation of the filter algorithm. The new filter is more
1267     accurate and supports all gig filter types, including bandreject
1268     and lowpass turbo.
1269 persson 903 - real support for 24 bit samples - samples are not truncated to
1270     16 bits anymore
1271     - support for aftertouch (channel pressure, not polyphonic
1272     aftertouch)
1273 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1274     amplifying from 0)
1275 persson 696
1276 schoenebeck 711 * LSCP server:
1277     - fixed application exit on broken pipe error (fixes bug #20)
1278 iliev 793 - fixed the notification messages delay due to lack of
1279     network activity (fixes bug #26)
1280 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1281     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1282 schoenebeck 711
1283 schoenebeck 838 * audio driver:
1284     - added aRts audio output driver (by no means RT safe)
1285    
1286 schoenebeck 775 * MIDI driver:
1287     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1288     messages several times instead of once
1289 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1290     for events (i.e. for offline rendering based MIDI drivers)
1291 persson 922 - added checks for bad MIDI data
1292 schoenebeck 775
1293 schoenebeck 900 * linuxsampler application:
1294     - show available sampler engine types on startup
1295    
1296 schoenebeck 705 * general changes:
1297     - support for muting sampler channels and solo mode of the same, two new
1298     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1299     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1300     introduced for this, the behavior is the same like on a mixer console
1301 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1302     --enable-process-muted-channels which can be used to enable the
1303     processing of muted channels.
1304 iliev 777 - support for sostenuto pedal
1305 iliev 779 - support for monitoring the total number of active voices
1306 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1307     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1308 persson 835 - fixed some memory management errors
1309 persson 841 - fixed some concurrency problems that could lead to crashes when
1310     LSCP commands were executed
1311 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1312     sampler channel (fixes bug #36)
1313 schoenebeck 705
1314 schoenebeck 692 Version 0.3.3 (15 July 2005)
1315 schoenebeck 686
1316     * packaging changes:
1317     - fixed compilation with gcc 4.0
1318    
1319 schoenebeck 687 * Gigasampler format engine:
1320     - LFO preprocessing was performed even though the respective LFO was
1321     disabled by the instrument patch (minor efficiency fix)
1322 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1323     for volume ramp downs in the same fragment (needed for current voice
1324     stealing implementation) then simply inform the user with a warning
1325     about possible click sounds and reduce the volume ramp down
1326     appropriately instead of cancelling the audio device connection
1327 schoenebeck 687
1328 schoenebeck 677 Version 0.3.2 (24 June 2005)
1329 schoenebeck 609
1330     * packaging changes:
1331     - updated autotools build files to compile on OS X
1332     (conditional compilation of CoreMIDI and MidiShare drivers)
1333 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1334     './configure --disable-asm' (definitely not recommended)
1335 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1336     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1337     (due to 'dist-bzip2' automake option)
1338 schoenebeck 649
1339     * Gigasampler format engine:
1340     - support for the gig parameters for "release velocity response" curves
1341     - fine tuning of the EGADSR envelope
1342     - volume of release triggered samples now depends on note-on velocity,
1343     note length and gig parameter "release trigger decay" instead of
1344     note-off velocity.
1345 schoenebeck 663 - revised voice stealing
1346     (fixes crash and endless loop caused by voice stealing)
1347 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1348 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1349     instead of when the respective voice is actually launched
1350     (fixes undefined behavior if stolen voices belonged to a key group -
1351     this case was followed by a "killed voice survived" error message)
1352 schoenebeck 669 - fixed minor issue with null/silence samples
1353     (those stole voices even though they don't need a voice at all which
1354     resulted in "voice stealing didn't work out" messages)
1355 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1356     instrument or audio output device change
1357 schoenebeck 654
1358 schoenebeck 620 * LSCP server:
1359 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1360 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1361 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1362 schoenebeck 609
1363 schoenebeck 668 * linuxsampler application:
1364     - added command line parameters --lscp-addr and --lscp-port to override
1365     default IP address and port of LSCP server
1366    
1367 schoenebeck 579 Version 0.3.1 (24 May 2005)
1368    
1369     * initial release
