Fri Jun 23 12:24:58 2017 UTC (6 years, 9 months ago) by schoenebeck
File size: 74342 byte(s)
* Revised fundamental C++ classes "Thread", "Mutex" and
  "Condition" which fixes potential undefined behavior
  (note: this addresses mainly the POSIX implementation,
   Win32 is untested yet and would also need an update).
* Bumped version (2.0.0.svn64).

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 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
48     fixes potential undefined behavior.
49 persson 2837
50 schoenebeck 2866 * packaging changes:
51     - removed unnecessary dependency to libuuid
52     (originated by libgig's usage of it)
53 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
54     auto detect whether it (sh/c)ould output its messages in color.
55 schoenebeck 2866
56 schoenebeck 2871 * Real-time instrument scripts:
57     - Implemented scheduler for delayed MIDI events and for suspended scripts.
58     - Built-in script function "wait()": implemented support for function's
59     "duration-us" argument, thus scripts using this function are now
60     correctly resumed after the requested amount of microseconds.
61     - Built-in script function "play_note()": implemented support for
62     function's "duration-us" argument, thus notes triggered with this
63     argument are now correctly released after the requested amount of
64     microseconds.
65     - Fix: script events were not cleared when engine channel was reset,
66     potentially causing undefined behavior.
67     - Fixed crash which happened when trying to reference an undeclared
68     variable.
69 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
70     special value -1 for "duration-us" argument, which will cause the
71     triggered note to be released once the original note was released.
72 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
73     - Added new API method ScriptVM::syntaxHighlighting() which provides
74     a convenient syntax highlighting backend for external instrument
75     script editor applications.
76 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
77     - Extended parser issues to provide not only first line and first
78     column, but also last line and last column of issue (thus marking
79     the precise span of the issue within the source code).
80 schoenebeck 2902 - Reload script automatically after being modified by an instrument
81     editor.
82 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
83     like "on note end on".

87 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
88     - Implemented built-in script function "change_reso()".
89     - Implemented built-in script function "event_status()".
90     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
91     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
92     "event_status()" function.
93     - NKSP language: Added support for bitwise operators ".or.", ".and."
94     and ".not.".
95     - NKSP language scanner: Fixed IDs matching to require at least one
96     character (i.e. when matching function names or variable names).
97     - NKSP language scanner: disabled unusued rules.
98 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
99     be distinguished engine internally from "real" MIDI note on/off
100     events in order to avoid misbehaviors like hanging notes.
101 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
102     - Implemented built-in script variable "$NKSP_REAL_TIMER".
103     - Implemented built-in script variable "$NKSP_PERF_TIMER".
104     - Implemented built-in script variable "$ENGINE_UPTIME".
105 schoenebeck 2945 - Implemented built-in script function "inc()".
106     - Implemented built-in script function "dec()".
107     - NKSP language fix: division expressions were evaluated too often.
108     - NKSP language fix: string concatenation operator was right
109     associative instead of left (to right).
110 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
111     (i.e. "if end if").
112 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
113     - Implemented built-in script variable "$NI_CALLBACK_ID".
114     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
115     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
116     - Added support for read-only built-in variables (respectively
117     handled by the script parser).
118     - Added built-in script constant "$NI_CB_TYPE_INIT".
119     - Added built-in script constant "$NI_CB_TYPE_NOTE".
120     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
121     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

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

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

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

264     in order to get rid of warnings from automake 1.14
265 persson 2382
266 persson 2086 * general changes:
267 iliev 2012 - Refactoring: moved the independent code from
268     the Gigasampler format engine to base classes
269 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
270     respective profiling code is currently broken
271 schoenebeck 2053 - Introduced support for optional environment variable
272     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
273     where the sampler shall look for instrument editor plugins
274     (patch by Luis Garrido, slightly modified).
275 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
276     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
277     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
278     note (in this implementation of the sampler its simply hard routed to
279     the 1st effect send of the sampler channel, no matter what the actual
280     effect type is)
281     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
282     note (in this implementation of the sampler its simply hard routed to
283     the 2nd effect send of the sampler channel, no matter what the actual
284     effect type is)
285 schoenebeck 2124 - implemented support for internal LADSPA effects
286 schoenebeck 2140 - raised limit of program change queue from 100 to 512
287     (as suggested by Alex Stone)
288 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
289 iliev 2296 - experimental support for per voice equalization
290 iliev 2306 - added command line option --exec-after-init
291 schoenebeck 2330 - Introduced new C++ API method:
292     EngineChannel::InstrumentFileName(int index)
293     allowing to retrieve the whole list of files used for the loaded
294     instrument on an engine channel (a.k.a. part). Some GigaStudio
295     instruments for example are splitted over several files like
296     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
297 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
298     - Added new C++ API method Sampler::GetGlobalMaxStreams().
299     - Added new C++ API method Sampler::SetGlobalMaxVoices().
300     - Added new C++ API method Sampler::SetGlobalMaxStreams().
301 schoenebeck 2377 - Various "const" and "restrict" optimizations.
302 persson 2382 - all engines: add pan CC value to instrument pan parameter before
303     applying panning, instead of using two separate pan functions in
304     series (#182)
305 persson 2427 - added a lock guard class for exception safe mutex handling and
306     used it everywhere appropriate
307 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
308     - Exposed scale tuning to C++ API (along to the already existing standard
309     SysEx way).
310 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
311     and broken for ppc64. (Seq_cst loads and stores are actually not
312     used in LS, so the bug wasn't noticable.)
313     - lsatomic.h: added ARMv7 support
314 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
315     added various new C++ methods for this new feature / design change, old
316     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
317     as deprecated but are still there and should provide full behavior
318     backward compatibility).
319     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
320     unsafe and caused compilation error with clang 2.x).
321 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
322 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
323     sampler from the command line by providing LSCP aware features.
324 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
325     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
326     - VirtualMidiDevice: Added support for pitch bend.
327 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
328     polyphonic key pressure events (so far polyphonic pressure was not
329     supported at all, and channel pressure was rerouted as CC128 but not
330     used so far).
331 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
332     code is shared by all sampler engine implemementations, however only the
333     gig file format currently provides support for storing instrument scripts
334     (as LinuxSampler extension to the original GigaStudio 4 format).
335 iliev 2012
336 persson 2043 * Gigasampler format engine:
337     - implemented the "round robin keyboard" dimension
338     - fixed round robin and random dimensions for cases when number of
339     dimension zones is not a power of two
340     - made round robin use a counter for each region instead of each
341     key
342 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
343     - bugfix: filter keyboard tracking was broken
344     - filter performance fix (an unnecessary copy was made of the
345     filter parameters in each sub fragment)
346     - handle special case when pan parameter in gig file has max or
347     min value
348 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
349     doesn't sound naturally with a drumkit
350 persson 2408 - fixed EG1 modulation when attack or release is zero
351 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
352 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
353     conditions (see also previous commit on libgig).
354 persson 2673 - fixed behaviour of filter LFO
355 persson 2043
356 schoenebeck 2047 * SFZ format engine:
357 iliev 2012 - Initial implementation (not usable yet)
358 persson 2055 - added support for v2 multiple stage envelope generators
359     - added a fine-tuned v1 envelope generator instead of using the
360     one from the gig engine
361 persson 2058 - fixed memory leak and memory handling errors
362 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
363 persson 2058 - allow non-numerical key values ("C#4" for example)
364     - "key" opcode now sets pitch_keycenter too
365     - fixed error when unloading instrument with same sample used by
366     multiple regions
367     - added some opcode aliases, like loopmode for loop_mode, to be
368     more compatible
369 persson 2061 - added support for trigger=release and rt_decay

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

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

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

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

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

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

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

885     instrument database compilable
886 schoenebeck 1930 - added instrument database support on Windows
887     works with both standalone mode and VST plugin.
888     the instruments DB file is located in
889     %USERPROFILE%\.linuxsampler\instruments.db which allows different
890     databases for each windows user
891     if no DB is present it automatically creates the .linuxsampler subdir
892     and then creates an empty DB
893 persson 1943 - fixed recursive import, which was broken on Windows
894 iliev 1603
895 persson 1644 * Gigasampler format engine:
896     - fixed a memory leak that could happen when a channel was deleted

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

979     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
980     GET MIDI_INPUT_DRIVER INFO
981     GET MIDI_INPUT_DRIVER_PARAMETER INFO

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

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

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

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

1048 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1049     API header files anymore
1050 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1051     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1052 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1053     capable to execute our autoconf environment, thus no need anymore
1054     to maintain the compile time configuration file (osx/version.h) for
1055     OSX manually (patch by Toshi Nagata)
1056 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1057     parameters
1058 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1059     C++ API header files, all implementation internal global definitions
1060     are now in global_private.h
1061     - atomic.h is not exposed to the C++ API anymore
1062     - no need to include config.h anymore for using LS's API header files
1063     - fixed warnings in API doc generation

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