* NKSP: Added built-in script function "change_pan_time()".
* NKSP: Added built-in script function "change_pan_curve()".
* Bumped version (2.0.0.svn75).

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).

130     - Added built-in script constant "$NI_CB_TYPE_NOTE".
131     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

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

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.

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.
194 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
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.
214     - NKSP language: Raise parser warning if array variable is accessed with
215     an index that exceeds the array's size.

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 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
246     to avoid the editor app to crash on ill-formed text input.
247 schoenebeck 3335 - Added built-in script function "change_pan_time()".
248     - Added built-in script function "change_pan_curve()".
249 schoenebeck 2871
250 schoenebeck 3050 * Instruments DB:
251     - Fixed memory access bug of general DB access code which lead to
252     undefined behavior.
253 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
254     - The instrument DB path of linuxsampler's --create-instruments-db argument
255     is now optional, if it is missing, then a default location is used.
256 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
257     - Added support for scanning Sound Font (.sf2) files.
258 schoenebeck 3101 - Fixed undefined DB transaction behavior.

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

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

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

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

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

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

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

919     instrument database compilable
920 schoenebeck 1930 - added instrument database support on Windows
921     works with both standalone mode and VST plugin.
922     the instruments DB file is located in
923     %USERPROFILE%\.linuxsampler\instruments.db which allows different
924     databases for each windows user
925     if no DB is present it automatically creates the .linuxsampler subdir
926     and then creates an empty DB
927 persson 1943 - fixed recursive import, which was broken on Windows
928 iliev 1603
929 persson 1644 * Gigasampler format engine:
930     - fixed a memory leak that could happen when a channel was deleted

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

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

1018 iliev 1847 - fixed crash when changing the audio output device of a sampler
1019     channel with loaded instrument and start playing notes
1020 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1021 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

1040     - bugfix: the thread used by an editor plugin didn't die when the
1041     editor closed
1042 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1043     out all the space. operator--() did not apply size_mask after
1044     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1045     order to avoid problems with the _NonVolatileReader functions.
1046     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1047     GetWriteSpace(). Since this function is currently only used in
1048     the stream's qsort() compare function, it didn't trigger any
1049     bugs.
1050     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1051     24bit mode too. Faster method to read 24bit words on little

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