File size: 75330 byte(s)
* NKSP: Removed max. value limitation of built-in functions
  "change_attack()", "change_decay()" and "change_release()" to
  i.e. allow passing 2000000 for doubling the respective time.
* Bumped version (2.0.0.svn68).

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

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

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

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

175 schoenebeck 3214 - Implemented built-in script function "change_velo()".
176     - Implemented built-in script function "change_note()".
177 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
178     intuitive behavior if used in combination with "change_vol_time()" or
179     "change_tune_time()" respectively: now tuning/volume changes are only
180     assigned (without delay) immediately to a new note if the respective
181     timing function has not been called before, otherwise the volume/tuning
182     changes are automatically faded (before, only the event's time stamp was
183     relevant).
184 schoenebeck 3221 - Implemented built-in script function "array_equal()".
185     - Implemented built-in script function "search()".
186     - Implemented built-in script function "sort()".
187     - NKSP Fix: Never suspend "init" event handlers.
188 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
189     available for gig format engine).
190 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
191     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
192     - Implemented built-in script function "change_vol_curve()".
193     - Implemented built-in script function "change_tune_curve()".
194 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
195     offset with argument 3, where special value -1 means to use the regular
196     sample offset as defined by the instrument file.
197 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
198     - Built-in variable $EVENT_NOTE is now a read-only variable.
199     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
200     - built-in "play_note()" function now accepts -2 for its fourth argument
201     (note duration) which means the life time of the note shall be sticked
202     to the requested note number of argument 1.
203     - Fix: built-in "play_note()" function now returns 0 as result value if
204     -1 was passed for its fourth argument (note duration) and the respective
205     parent note is already gone.
206 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
207 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
208     - NKSP language: Raise parser warning if array variable is accessed with
209     an index that exceeds the array's size.
210 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
211 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
212     code blocks.
213 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
214     another script handler by passing its callback ID.
215 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
216     "init" event handlers.
217 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
218     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
219     to retrieve all code blocks filtered out by the preprocessor.
220 schoenebeck 3293 - Added built-in script function "fork()".
221     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
222     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
223     - Fixed potential crash when accessing dynamic built-in array variables.
224 schoenebeck 3296 - Added built-in script function "callback_status()".
225     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
226     - Added built-in constant $CALLBACK_STATUS_QUEUE.
227     - Added built-in constant $CALLBACK_STATUS_RUNNING.
228 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
229     "change_decay()" and "change_release()" to i.e. allow passing 2000000
230     for doubling the respective time.
231 schoenebeck 2871
232 schoenebeck 3050 * Instruments DB:
233     - Fixed memory access bug of general DB access code which lead to
234     undefined behavior.
235 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
236     - The instrument DB path of linuxsampler's --create-instruments-db argument
237     is now optional, if it is missing, then a default location is used.
238 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
239     - Added support for scanning Sound Font (.sf2) files.
240 schoenebeck 3101 - Fixed undefined DB transaction behavior.

278 persson 2519 - enabled automake 'subdir-objects' option and moved external
279     source references (vst, au, asio) from makefiles to cpp files,
280     in order to get rid of warnings from automake 1.14
281 persson 2382
282 persson 2086 * general changes:
283 iliev 2012 - Refactoring: moved the independent code from
284     the Gigasampler format engine to base classes
285 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
286     respective profiling code is currently broken
287 schoenebeck 2053 - Introduced support for optional environment variable
288     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
289     where the sampler shall look for instrument editor plugins
290     (patch by Luis Garrido, slightly modified).
291 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
292     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
293     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
294     note (in this implementation of the sampler its simply hard routed to
295     the 1st effect send of the sampler channel, no matter what the actual
296     effect type is)
297     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
298     note (in this implementation of the sampler its simply hard routed to
299     the 2nd effect send of the sampler channel, no matter what the actual
300     effect type is)
301 schoenebeck 2124 - implemented support for internal LADSPA effects
302 schoenebeck 2140 - raised limit of program change queue from 100 to 512
303     (as suggested by Alex Stone)
304 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
305 iliev 2296 - experimental support for per voice equalization
306 iliev 2306 - added command line option --exec-after-init
307 schoenebeck 2330 - Introduced new C++ API method:
308     EngineChannel::InstrumentFileName(int index)
309     allowing to retrieve the whole list of files used for the loaded
310     instrument on an engine channel (a.k.a. part). Some GigaStudio
311     instruments for example are splitted over several files like
312     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
313 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
314     - Added new C++ API method Sampler::GetGlobalMaxStreams().
315     - Added new C++ API method Sampler::SetGlobalMaxVoices().
316     - Added new C++ API method Sampler::SetGlobalMaxStreams().
317 schoenebeck 2377 - Various "const" and "restrict" optimizations.
318 persson 2382 - all engines: add pan CC value to instrument pan parameter before
319     applying panning, instead of using two separate pan functions in
320     series (#182)
321 persson 2427 - added a lock guard class for exception safe mutex handling and
322     used it everywhere appropriate
323 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
324     - Exposed scale tuning to C++ API (along to the already existing standard
325     SysEx way).
326 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
327     and broken for ppc64. (Seq_cst loads and stores are actually not
328     used in LS, so the bug wasn't noticable.)
329     - lsatomic.h: added ARMv7 support
330 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
331     added various new C++ methods for this new feature / design change, old
332     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
333     as deprecated but are still there and should provide full behavior
334     backward compatibility).
335     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
336     unsafe and caused compilation error with clang 2.x).
337 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
338 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
339     sampler from the command line by providing LSCP aware features.
340 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
341     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
342     - VirtualMidiDevice: Added support for pitch bend.
343 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
344     polyphonic key pressure events (so far polyphonic pressure was not
345     supported at all, and channel pressure was rerouted as CC128 but not
346     used so far).
347 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
348     code is shared by all sampler engine implemementations, however only the
349     gig file format currently provides support for storing instrument scripts
350     (as LinuxSampler extension to the original GigaStudio 4 format).
351 iliev 2012
352 persson 2043 * Gigasampler format engine:
353     - implemented the "round robin keyboard" dimension
354     - fixed round robin and random dimensions for cases when number of
355     dimension zones is not a power of two
356     - made round robin use a counter for each region instead of each
357     key
358 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
359     - bugfix: filter keyboard tracking was broken
360     - filter performance fix (an unnecessary copy was made of the
361     filter parameters in each sub fragment)
362     - handle special case when pan parameter in gig file has max or
363     min value
364 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
365     doesn't sound naturally with a drumkit
366 persson 2408 - fixed EG1 modulation when attack or release is zero

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

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

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

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

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

860 iliev 1829 - added (experimental) CoreAudio driver
861 persson 1888 - applied old fixes to the ASIO driver that were included in the
862     previous binary release but accidentally never committed to CVS
863     (fixes #117)
864 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
865     win64)

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

901     instrument database compilable
902 schoenebeck 1930 - added instrument database support on Windows
903     works with both standalone mode and VST plugin.
904     the instruments DB file is located in
905     %USERPROFILE%\.linuxsampler\instruments.db which allows different
906     databases for each windows user
907     if no DB is present it automatically creates the .linuxsampler subdir
908     and then creates an empty DB
909 persson 1943 - fixed recursive import, which was broken on Windows
910 iliev 1603
911 persson 1644 * Gigasampler format engine:
912     - fixed a memory leak that could happen when a channel was deleted

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

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

1000 iliev 1847 - fixed crash when changing the audio output device of a sampler
1001     channel with loaded instrument and start playing notes
1002 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1003 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1004     PowerPC, which probably could cause crashes on that platform
1005 persson 1889 - fixed a memory management error which could cause a crash when a
1006     plugin was unloaded

1022     - bugfix: the thread used by an editor plugin didn't die when the
1023     editor closed
1024 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1025     out all the space. operator--() did not apply size_mask after
1026     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1027     order to avoid problems with the _NonVolatileReader functions.
1028     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1029     GetWriteSpace(). Since this function is currently only used in
1030     the stream's qsort() compare function, it didn't trigger any
1031     bugs.
1032     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1033     24bit mode too. Faster method to read 24bit words on little

1047 schoenebeck 1495 - added MME Windows MIDI driver
1048 senoner 1485
1049 schoenebeck 1471 * LSCP server:
1050     - added support for Windows style path / filenames, however with
1051     forward slash path separators instead of backslash
1052     (i.e. "C:/foo/bar.gig")
1053 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1054     apostrophes as well
1055 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1056     "LIST FILE INSTRUMENTS <file>" and
1057     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1058     about an arbitrary instrument file on the system where the sampler is
1059     running on

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