* gig Engine: Added support for controlling whether the individual
  EGADSR stages may be aborted (as LinuxSampler extension to the
  original GigaStudio 4 format).
* Bumped version (2.0.0.svn73).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
6     - Added support for sfz extension opcode 'script' which may be used to
7     load real-time instrument script file (NKSP script language).
8 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 3291 - sfz parser: allow missing space between header and opcode
11 persson 2856
12 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
13 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14     cutoff settings.
15 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16     all if an up-pitch of more than 40 semi tones was requested (I don't
17     think there is any stock gig sound that requires this behavior to
18     resemble its original sound).
19 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
20     be aborted (as LinuxSampler extension to the original GigaStudio 4
21     format).
22 schoenebeck 3072
23 persson 2837 * general changes:
24     - fixed printf type errors (mostly in debug messages)
25 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
26 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
27     allowing to sort data efficiently in real-time safe manner.
28     - RTList class: added methods for moving/inserting elements to arbitrary
29     position within a list.
30     - RTList class: added method fromPtr() for creating an Iterator object from
31     a raw element pointer.
32     - Attempt to partly fix resetting engine channels vs. resetting engine, an
33     overall cleanup of the Reset*(), ConnectAudioDevice(),
34     DisconnectAudioDevice() API methods would still be desirable though,
35     because the current situation is still inconsistent and error prone.
36 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
37     being directly assigned to a keyboard key. This allows more fine graded
38     processing of voices, which is i.e. required for certain instrument
39     script features.
40 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
41     (CC #64) events.
42     - Fix: Release trigger voices can now also distinguish correctly between
43     note-off and sustain pedal up events.
44 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
45     (while slow rate of crossfade smoother is preserved) to allow quick
46     volume and pan changes by instrument scripts for instance.
47 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
48     properly and thus were ignored for certain uses.
49 schoenebeck 3018 - Added new C++ API method
50     VirtualMidiDevice::SendChannelPressureToSampler().
51 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
52     sub threads is 16-byte aligned
53 schoenebeck 3054 - fixed numerous compiler warnings
54 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
55 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
56     fixes potential undefined behavior.
57 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
58     have a valid sample mapped (fixes bug #252).
59     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
60 persson 2837
61 schoenebeck 2866 * packaging changes:
62     - removed unnecessary dependency to libuuid
63     (originated by libgig's usage of it)
64 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
65     auto detect whether it (sh/c)ould output its messages in color.
66 schoenebeck 2866
67 schoenebeck 2871 * Real-time instrument scripts:
68     - Implemented scheduler for delayed MIDI events and for suspended scripts.
69     - Built-in script function "wait()": implemented support for function's
70     "duration-us" argument, thus scripts using this function are now
71     correctly resumed after the requested amount of microseconds.
72     - Built-in script function "play_note()": implemented support for
73     function's "duration-us" argument, thus notes triggered with this
74     argument are now correctly released after the requested amount of
75     microseconds.
76     - Fix: script events were not cleared when engine channel was reset,
77     potentially causing undefined behavior.
78     - Fixed crash which happened when trying to reference an undeclared
79     variable.
80 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
81     special value -1 for "duration-us" argument, which will cause the
82     triggered note to be released once the original note was released.
83 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
84     - Added new API method ScriptVM::syntaxHighlighting() which provides
85     a convenient syntax highlighting backend for external instrument
86     script editor applications.
87 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
88     - Extended parser issues to provide not only first line and first
89     column, but also last line and last column of issue (thus marking
90     the precise span of the issue within the source code).
91 schoenebeck 2902 - Reload script automatically after being modified by an instrument
92     editor.
93 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
94     like "on note end on".

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

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

165     - Implemented built-in script function "change_tune_time()".
166     - Implemented built-in script function "fade_in()".
167     - Implemented built-in script function "fade_out()".
168     - Fixed acceptance of wrong data type of parameters passed to built-in
169     script functions "change_vol()", "change_tune()", "change_pan()",
170     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
171     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
172     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
173 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
174     of its possible parameter selections.
175     - Added built-in script function "set_event_par()" and implemented some
176     of its possible parameter selections.
177 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
178 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
179 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
180     built-in function "ignore_controller()".
181 schoenebeck 3214 - Implemented built-in script function "change_velo()".
182     - Implemented built-in script function "change_note()".
183 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
184     intuitive behavior if used in combination with "change_vol_time()" or
185     "change_tune_time()" respectively: now tuning/volume changes are only
186     assigned (without delay) immediately to a new note if the respective
187     timing function has not been called before, otherwise the volume/tuning
188     changes are automatically faded (before, only the event's time stamp was
189     relevant).
190 schoenebeck 3221 - Implemented built-in script function "array_equal()".
191     - Implemented built-in script function "search()".
192     - Implemented built-in script function "sort()".
193     - NKSP Fix: Never suspend "init" event handlers.

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

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

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

762     after MIDI/audio device creation failure
763 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
764     instruments were uselessly precached with zero samples, however it still
765     took the full preloading time and on 1st program change the respective
766     instrument was completely reloaded again.
767 persson 2277 - fixed handling of rapid bank select and program change messages
768     sent to the same sampler channel (patch from the Open Octave

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

846 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
847     be switched on by command line option "--stacktrace" (the automatic
848     stacktrace mechanism seems to be broken on most systems at the moment)
849 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
850     a pointer to the launched InstrumentEditor object
851 schoenebeck 1876 - added optional 3rd party user data parameter for following

873 persson 1748 jack_client_new
874 iliev 1829 - added (experimental) CoreAudio driver
875 persson 1888 - applied old fixes to the ASIO driver that were included in the
876     previous binary release but accidentally never committed to CVS
877     (fixes #117)
878 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
879     win64)

893     exception when getting parameters from a disconnected device
894 schoenebeck 1599
895 persson 1651 * MIDI driver:
896     - added JACK MIDI driver
897 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
898     want to (mis)use it for some purpose ("fixed" in all current MIDI
899     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
900 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
901 persson 1887 CoreMidi or AU

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

1013 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1014 iliev 1847 - fixed crash when changing the audio output device of a sampler
1015     channel with loaded instrument and start playing notes
1016 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1017 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

1036     - bugfix: the thread used by an editor plugin didn't die when the
1037     editor closed
1038 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1039     out all the space. operator--() did not apply size_mask after
1040     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1041     order to avoid problems with the _NonVolatileReader functions.
1042     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1043     GetWriteSpace(). Since this function is currently only used in
1044     the stream's qsort() compare function, it didn't trigger any
1045     bugs.
1046     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1047     24bit mode too. Faster method to read 24bit words on little
1048     endian machines (x86): replaced 3 byte reads + shifts with a 1
1049     unaligned 32bit read and shift

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