File size: 74876 byte(s)
* Added built-in script function "callback_status()".
* Added built-in constant $CALLBACK_STATUS_TERMINATED.
* Added built-in constant $CALLBACK_STATUS_QUEUE.
* Added built-in constant $CALLBACK_STATUS_RUNNING.
* Bumped version (2.0.0.svn66).

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

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

124 schoenebeck 2953 - Implemented built-in script function "change_attack()".
125     - Implemented built-in script function "change_decay()".
126     - Implemented built-in script function "change_release()".
127 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
128     synthesis parameter changes immediately in case the respective note
129     was triggered at the same time, instead of scheduling the parameter
130     change, especially because it would cause some parameter types's
131     changes either to be ramped (i.e. change_vol()) or other types even
132     to have not effect at all (i.e. change_attack()).
133 schoenebeck 2965 - Implemented built-in script function "sh_left()".
134     - Implemented built-in script function "sh_right()".
135 schoenebeck 2970 - Implemented built-in script function "min()".

137 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
138     was loaded.
139     - NKSP built-in wait() script function: abort script execution if
140     a negative or zero wait time was passed as argument (since this is
141     a common indication of a bug either of the script or even of the
142     engine, which could lead to RT instability or even worse).
143 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
144     threatening scripts.
145 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
146 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
147     initializer list to an array variable.
148 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
149 schoenebeck 3076 - Implemented built-in script function "in_range()".

155     - Implemented built-in script function "change_tune_time()".
156     - Implemented built-in script function "fade_in()".
157     - Implemented built-in script function "fade_out()".
158     - Fixed acceptance of wrong data type of parameters passed to built-in
159     script functions "change_vol()", "change_tune()", "change_pan()",
160     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
161     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
162     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
163 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
164     of its possible parameter selections.
165     - Added built-in script function "set_event_par()" and implemented some
166     of its possible parameter selections.
167 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
168 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.

170     built-in function "ignore_controller()".
171 schoenebeck 3214 - Implemented built-in script function "change_velo()".
172     - Implemented built-in script function "change_note()".
173 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
174     intuitive behavior if used in combination with "change_vol_time()" or
175     "change_tune_time()" respectively: now tuning/volume changes are only
176     assigned (without delay) immediately to a new note if the respective
177     timing function has not been called before, otherwise the volume/tuning
178     changes are automatically faded (before, only the event's time stamp was
179     relevant).
180 schoenebeck 3221 - Implemented built-in script function "array_equal()".
181     - Implemented built-in script function "search()".
182     - Implemented built-in script function "sort()".
183     - NKSP Fix: Never suspend "init" event handlers.
184 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
185     available for gig format engine).
186 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
187     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
188     - Implemented built-in script function "change_vol_curve()".
189     - Implemented built-in script function "change_tune_curve()".
190 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
191     offset with argument 3, where special value -1 means to use the regular
192     sample offset as defined by the instrument file.
193 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
194     - Built-in variable $EVENT_NOTE is now a read-only variable.
195     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
196     - built-in "play_note()" function now accepts -2 for its fourth argument
197     (note duration) which means the life time of the note shall be sticked
198     to the requested note number of argument 1.
199     - Fix: built-in "play_note()" function now returns 0 as result value if
200     -1 was passed for its fourth argument (note duration) and the respective
201     parent note is already gone.
202 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
203 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
204     - NKSP language: Raise parser warning if array variable is accessed with
205     an index that exceeds the array's size.
206 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.

210     another script handler by passing its callback ID.
211 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
212     "init" event handlers.
213 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
214     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
215     to retrieve all code blocks filtered out by the preprocessor.
216 schoenebeck 3293 - Added built-in script function "fork()".
217     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
218     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
219     - Fixed potential crash when accessing dynamic built-in array variables.
220 schoenebeck 3296 - Added built-in script function "callback_status()".
221     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
222     - Added built-in constant $CALLBACK_STATUS_QUEUE.
223     - Added built-in constant $CALLBACK_STATUS_RUNNING.
224 schoenebeck 2871
225 schoenebeck 3050 * Instruments DB:
226     - Fixed memory access bug of general DB access code which lead to
227     undefined behavior.
228 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
229     - The instrument DB path of linuxsampler's --create-instruments-db argument
230     is now optional, if it is missing, then a default location is used.
231 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
232     - Added support for scanning Sound Font (.sf2) files.
233 schoenebeck 3101 - Fixed undefined DB transaction behavior.

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

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

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

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

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

852 persson 1748 jack_client_new
853 iliev 1829 - added (experimental) CoreAudio driver
854 persson 1888 - applied old fixes to the ASIO driver that were included in the
855     previous binary release but accidentally never committed to CVS
856     (fixes #117)
857 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

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

893 persson 1908 - work-around for missing fnmatch function on Windows to make
894     instrument database compilable
895 schoenebeck 1930 - added instrument database support on Windows
896     works with both standalone mode and VST plugin.
897     the instruments DB file is located in
898     %USERPROFILE%\.linuxsampler\instruments.db which allows different
899     databases for each windows user
900     if no DB is present it automatically creates the .linuxsampler subdir
901     and then creates an empty DB
902 persson 1943 - fixed recursive import, which was broken on Windows
903 iliev 1603
904 persson 1644 * Gigasampler format engine:
905     - fixed a memory leak that could happen when a channel was deleted

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

992 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
993 iliev 1847 - fixed crash when changing the audio output device of a sampler
994     channel with loaded instrument and start playing notes
995 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
996 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
997     PowerPC, which probably could cause crashes on that platform
998 persson 1889 - fixed a memory management error which could cause a crash when a
999     plugin was unloaded
1000 persson 1896 - bugfix: two private structs had the same name, which could cause

1015     - bugfix: the thread used by an editor plugin didn't die when the
1016     editor closed
1017 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1018     out all the space. operator--() did not apply size_mask after
1019     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1020     order to avoid problems with the _NonVolatileReader functions.
1021     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1022     GetWriteSpace(). Since this function is currently only used in
1023     the stream's qsort() compare function, it didn't trigger any
1024     bugs.
1025     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1026     24bit mode too. Faster method to read 24bit words on little
1027     endian machines (x86): replaced 3 byte reads + shifts with a 1
1028     unaligned 32bit read and shift

1038 senoner 1500
1039 senoner 1485 * MIDI driver:
1040 schoenebeck 1495 - added MME Windows MIDI driver
1041 senoner 1485
1042 schoenebeck 1471 * LSCP server:
1043     - added support for Windows style path / filenames, however with
1044     forward slash path separators instead of backslash
1045     (i.e. "C:/foo/bar.gig")
1046 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1047     apostrophes as well
1048 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1049     "LIST FILE INSTRUMENTS <file>" and
1050     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1051     about an arbitrary instrument file on the system where the sampler is
1052     running on

1057 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1058     API header files anymore
1059 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1060     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1061 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1062     capable to execute our autoconf environment, thus no need anymore
1063     to maintain the compile time configuration file (osx/version.h) for
1064     OSX manually (patch by Toshi Nagata)
1065 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1066     parameters
1067 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1068     C++ API header files, all implementation internal global definitions
1069     are now in global_private.h
1070     - atomic.h is not exposed to the C++ API anymore
1071     - no need to include config.h anymore for using LS's API header files
1072     - fixed warnings in API doc generation
1073 schoenebeck 1065
1074 schoenebeck 947 * general changes:
1075     - replaced the old, confusing MIDI program change mechanism by a
1076     flexible MIDI instrument mapper which allows to map arbitrary
1077 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1078 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1079     loaded on the respective channel when such MIDI program change
1080     messages arrive, beside that, each entry allows to define a life-time
1081     strategy for the instrument, so the user can define whether the
1082     instrument should i.e. be permanently loaded (to be able to switch
1083     quickly among sounds) or i.e. loaded just on demand when the
1084     respective program change arrives (to safe RAM space), as well as a
1085     global volume factor for each entry, so the user can adjust the volume
1086     dynamic of his mapped instrument collection without having to modify
1087 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1088     MIDI instrument maps and assign each sampler channel individually
1089     a certain map, so that i.e. separation of normal instruments and
1090     drumkits is possible
1091 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1092     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1093 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1094     due to a constant size RingBuffer FIFO which is now replaced by a
1095     dynamic (unlimited) size std::list FIFO
1096 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1097     output channels for being processed by external effect processors
1098     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1099     controllers
1100 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1101 iliev 1130 - Implemented new, improved notification system
1102 schoenebeck 1149 - fixed compilation errors regarding OSX
1103     (patch by Toshi Nagata)
1104 iliev 1161 - implemented instruments database
1105 iliev 1345 - added support for escape sequences to the instruments database
1106 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1107     within the sampler's process (by using instrument editor plugins),
1108     you'll notice the new "Registered instrument editors:" message on
1109 schoenebeck 1407 startup, added a new LSCP command:
1110     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1111 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1112     given sampler channel, the plugin path can be overridden at compile
1113     time with ./configure --enable-plugin-dir=/some/dir
1114 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1115     in the sampler's process to safely edit instruments while playing
1116     without a crash (hopefully) by either suspending single regions
1117     wherever possible or if unavoidable whole engine(s)
1118 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1119     policy and priority on thread level, set a minimum stack size for
1120     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1121     threads simply inherited properties of starting thread instead of
1122     setting their own policy and priority
1123 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1124     main process did not wait for the stack trace process to finish
1125     its output
1126 persson 1248 - fixed some minor memory leaks
1127 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1128     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1129 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1130     register, to avoid relocations in the text segment at runtime)
1131 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1132 schoenebeck 947
1133     * MIDI driver:
1134     - dispatch bank select (MSB and LSB) messages
1135    
1136 schoenebeck 1049 * audio driver:
1137     - the ALSA audio output driver parameters now reflect the correct
1138     parameter value ranges for the respective selected sound card
1139     (patch by Till Wimmer, a bit fixed and extended)
1140    
1141 persson 951 * Gigasampler format engine:
1142     - if a filter is used and EG2 finishes before EG1, let the voice
1143     die when EG2 has finished (this fixes a problem with clicks and
1144     voice starvation for some gigs)
1145 persson 1038 - playback is no longer disabled during instrument loading
1146     - all notes playing on a channel that changes its instrument keep
1147     playing with the old instrument until they get a note off
1148     command
1149 persson 1039 - EG fix: a release value of zero could cause noises or crash
1150 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1151 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1152     above max sustain level, which means that there is a decay phase
1153     even if sustain is 100%
1154 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1155     noises or crashes
1156 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1157 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1158     supplied to the configure script (fixes #46)
1159 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1160     instead of a fix value
1161 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1162     127 (solo mode) only kill voices if the respective mode really
1163     changed
1164 persson 951
1165 schoenebeck 1244 * LSCP server:
1166     - fixed compile time error for old Bison versions
1167     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1168 schoenebeck 1245 - parser now supports extended ASCII character set
1169     (up to ASCII code 255, i.e. includes now umlauts and accents)
1170     - filename arguments in LSCP commands now allow to use escape
1171     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1172     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1173     code value like \xf2) (fixes bug #24)
1174 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1175     least one of their text-based parameters (i.e. name, description):
1176     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1177     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1178     "SET DB_INSTRUMENT_DIRECTORY NAME",
1179     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1180     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1181     "FIND DB_INSTRUMENT_DIRECTORIES"
1182 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1183     occured, the unexpected character and the actually expected, possible
1184     character(s), the latter only if less than 5 possibilities)
1185 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1186     settings
1187 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1188     of strings were treated as being one string containing commas
1189     (fixes #57)
1190 schoenebeck 1244
1191 iliev 959 * Bug fixes:
1192     - fixed crash occurring on certain LSCP scripts (Bug 39)
1193 persson 1038 - another thread safety fix for lscp "load engine" and "set
1194     channel audio output device"
1195 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1196     on a sampler channel with connected MIDI device
1197 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1198     device connected to a sampler channel to number less then or equal
1199     to the index of the port to which the sampler channel is connected.
1200 iliev 1296 - The previous bindings were not been disconnected when altering
1201     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1202     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1203 iliev 1297 - The active stream/voice count statistic was incorrect.
1204 iliev 1298 - notification events were not been sent for some sampler
1205     channel changes
1206 iliev 1305 - added default min and max values to restrict the number of allowed
1207     audio output channels and MIDI input ports
1208 iliev 1306 - the connection to the PCM interface is now closed when destroying
1209     an audio output device
1210 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1211 iliev 959
1212 schoenebeck 1221 * test cases:
1213     - updated and fixed (haven't been touched in a while)
1214    
1215 schoenebeck 937 Version 0.4.0 (24 November 2006)
1216 persson 696
1217 schoenebeck 697 * packaging changes:
1218 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1219     to post-(un)install steps; added devel package for liblinuxsampler;
1220     to linuxsampler.spec (RPM)
1221 schoenebeck 697 - install necessary development header files for allowing 3rd party
1222     applications to link against liblinuxsampler
1223     - liblinuxsampler's API documentation can be generated with 'make docs'
1224     (Doxygen required)
1225 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1226     implementation (currently either an integer math solution or a
1227     di-harmonic approximation), automatic detection can be overriden
1228     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1229     configure script argument though (mandatory for cross-compilation)
1230 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1231     provided some on his own (as CXXFLAGS)
1232 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1233     messages
1234 schoenebeck 852 - added compile time options to allow disabling the various audio and
1235     MIDI drivers
1236 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1237     (patch by Ebrahim Mayat)
1238 schoenebeck 697
1239 persson 696 * Gigasampler format engine:
1240 schoenebeck 738 - extensive synthesis optimization
1241     (reimplementation of EGs and LFO(s), removed synthesis parameter
1242     prerendering and the synthesis parameter matrix in general, splitting
1243     each audio fragment into subfragments now where each subfragment uses
1244 persson 830 constant pitch and filter coefficients. The volume coefficient is
1245     linearly interpolated inside a subfragment, unless
1246     --disable-interpolate-volume is set.)
1247 persson 696 - fine tuning of the EG modulation parameters
1248 persson 729 - improved filter cutoff calculation by adding support for the
1249     following gig parameters: Cutoff freq (used when no cutoff
1250     controller is defined), Control invert, Minimum cutoff, Velocity
1251 persson 791 curve and Velocity range. The keyboard tracking now scales
1252     cutoff frequency instead of resonance.
1253 persson 877 - added support for gig parameter Resonance.
1254 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1255 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1256     which can be overridden with --enable-global-attenuation
1257 persson 783 - EG fixes: made the length of "attack hold" stage more
1258     accurate. Release stage can now start before attack stage
1259 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1260     time now has a minimal value to prevent clicks.
1261 persson 799 - fixed pitch changes larger than one octave
1262 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1263     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1264     all modes can be altered via standard GM messages, that is CC5 for
1265     altering portamento time, CC65 for enabling / disabling portamento
1266     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1267 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1268     parameter) and crossfade
1269 persson 831 - added support for the "attenuation controller threshold" gig
1270     parameter
1271 persson 832 - added smoothing of volume changes caused by control change
1272     messages
1273 persson 865 - sample loop parameters are now taken from the DimensionRegion
1274     instead of the wave chunk
1275     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1276     not equal to a power of two
1277 persson 877 - reimplementation of the filter algorithm. The new filter is more
1278     accurate and supports all gig filter types, including bandreject
1279     and lowpass turbo.
1280 persson 903 - real support for 24 bit samples - samples are not truncated to
1281     16 bits anymore
1282     - support for aftertouch (channel pressure, not polyphonic
1283     aftertouch)
1284 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1285     amplifying from 0)
1286 persson 696
1287 schoenebeck 711 * LSCP server:
1288     - fixed application exit on broken pipe error (fixes bug #20)
1289 iliev 793 - fixed the notification messages delay due to lack of
1290     network activity (fixes bug #26)
1291 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1292     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1293 schoenebeck 711
1294 schoenebeck 838 * audio driver:
1295     - added aRts audio output driver (by no means RT safe)
1296    
1297 schoenebeck 775 * MIDI driver:
1298     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1299     messages several times instead of once
1300 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1301     for events (i.e. for offline rendering based MIDI drivers)
1302 persson 922 - added checks for bad MIDI data
1303 schoenebeck 775
1304 schoenebeck 900 * linuxsampler application:
1305     - show available sampler engine types on startup
1306    
1307 schoenebeck 705 * general changes:
1308     - support for muting sampler channels and solo mode of the same, two new
1309     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1310     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1311     introduced for this, the behavior is the same like on a mixer console
1312 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1313     --enable-process-muted-channels which can be used to enable the
1314     processing of muted channels.
1315 iliev 777 - support for sostenuto pedal
1316 iliev 779 - support for monitoring the total number of active voices
1317 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1318     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1319 persson 835 - fixed some memory management errors
1320 persson 841 - fixed some concurrency problems that could lead to crashes when
1321     LSCP commands were executed
1322 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1323     sampler channel (fixes bug #36)
1324 schoenebeck 705
1325 schoenebeck 692 Version 0.3.3 (15 July 2005)
1326 schoenebeck 686
1327     * packaging changes:
1328     - fixed compilation with gcc 4.0
1329    
1330 schoenebeck 687 * Gigasampler format engine:
1331     - LFO preprocessing was performed even though the respective LFO was
1332     disabled by the instrument patch (minor efficiency fix)
1333 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1334     for volume ramp downs in the same fragment (needed for current voice
1335     stealing implementation) then simply inform the user with a warning
1336     about possible click sounds and reduce the volume ramp down
1337     appropriately instead of cancelling the audio device connection
1338 schoenebeck 687
1339 schoenebeck 677 Version 0.3.2 (24 June 2005)
1340 schoenebeck 609
1341     * packaging changes:
1342     - updated autotools build files to compile on OS X
1343     (conditional compilation of CoreMIDI and MidiShare drivers)
1344 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1345     './configure --disable-asm' (definitely not recommended)
1346 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1347     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1348     (due to 'dist-bzip2' automake option)
1349 schoenebeck 649
1350     * Gigasampler format engine:
1351     - support for the gig parameters for "release velocity response" curves
1352     - fine tuning of the EGADSR envelope
1353     - volume of release triggered samples now depends on note-on velocity,
1354     note length and gig parameter "release trigger decay" instead of
1355     note-off velocity.
1356 schoenebeck 663 - revised voice stealing
1357     (fixes crash and endless loop caused by voice stealing)
1358 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1359 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1360     instead of when the respective voice is actually launched
1361     (fixes undefined behavior if stolen voices belonged to a key group -
1362     this case was followed by a "killed voice survived" error message)
1363 schoenebeck 669 - fixed minor issue with null/silence samples
1364     (those stole voices even though they don't need a voice at all which
1365     resulted in "voice stealing didn't work out" messages)
1366 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1367     instrument or audio output device change
1368 schoenebeck 654
1369 schoenebeck 620 * LSCP server:
1370 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1371 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1372 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1373 schoenebeck 609
1374 schoenebeck 668 * linuxsampler application:
1375     - added command line parameters --lscp-addr and --lscp-port to override
1376     default IP address and port of LSCP server
1377    
1378 schoenebeck 579 Version 0.3.1 (24 May 2005)
1379    
1380     * initial release
