File size: 76932 byte(s)
* linuxsampler binary fix: option --create-instruments-db ignored
  subsequent optional argument due to glibc's implementation oddity
  which expects a "=" sign, but no space between them.
* Debian: Added build dependency to libsqlite3-dev for building
  linuxsampler with instruments DB support.
* Bumped version (2.0.0.svn76).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
6     - Added support for sfz extension opcode 'script' which may be used to
7     load real-time instrument script file (NKSP script language).
8 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 3291 - sfz parser: allow missing space between header and opcode
11 persson 2856
12 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
13 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14     cutoff settings.
15 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16     all if an up-pitch of more than 40 semi tones was requested (I don't
17     think there is any stock gig sound that requires this behavior to
18     resemble its original sound).
19 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
20     be aborted (as LinuxSampler extension to the original GigaStudio 4
21     format).
22 schoenebeck 3072
23 persson 2837 * general changes:
24     - fixed printf type errors (mostly in debug messages)
25 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
26 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
27     allowing to sort data efficiently in real-time safe manner.
28     - RTList class: added methods for moving/inserting elements to arbitrary
29     position within a list.
30     - RTList class: added method fromPtr() for creating an Iterator object from
31     a raw element pointer.
32     - Attempt to partly fix resetting engine channels vs. resetting engine, an
33     overall cleanup of the Reset*(), ConnectAudioDevice(),
34     DisconnectAudioDevice() API methods would still be desirable though,
35     because the current situation is still inconsistent and error prone.
36 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
37     being directly assigned to a keyboard key. This allows more fine graded
38     processing of voices, which is i.e. required for certain instrument
39     script features.
40 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
41     (CC #64) events.
42     - Fix: Release trigger voices can now also distinguish correctly between
43     note-off and sustain pedal up events.
44 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
45     (while slow rate of crossfade smoother is preserved) to allow quick
46     volume and pan changes by instrument scripts for instance.
47 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
48     properly and thus were ignored for certain uses.
49 schoenebeck 3018 - Added new C++ API method
50     VirtualMidiDevice::SendChannelPressureToSampler().
51 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
52     sub threads is 16-byte aligned
53 schoenebeck 3054 - fixed numerous compiler warnings
54 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
55 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
56     fixes potential undefined behavior.
57 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
58     have a valid sample mapped (fixes bug #252).
59     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
60 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
61     subsequent optional argument due to glibc's implementation oddity
62     which expects a "=" sign, but no space between them.
63 persson 2837
64 schoenebeck 2866 * packaging changes:
65     - removed unnecessary dependency to libuuid
66     (originated by libgig's usage of it)
67 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
68     auto detect whether it (sh/c)ould output its messages in color.
69 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
70     substitution variable.
71     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
72 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
73     linuxsampler with instruments DB support.
74 schoenebeck 2866
75 schoenebeck 2871 * Real-time instrument scripts:
76     - Implemented scheduler for delayed MIDI events and for suspended scripts.
77     - Built-in script function "wait()": implemented support for function's
78     "duration-us" argument, thus scripts using this function are now
79     correctly resumed after the requested amount of microseconds.
80     - Built-in script function "play_note()": implemented support for
81     function's "duration-us" argument, thus notes triggered with this
82     argument are now correctly released after the requested amount of
83     microseconds.
84     - Fix: script events were not cleared when engine channel was reset,
85     potentially causing undefined behavior.
86     - Fixed crash which happened when trying to reference an undeclared
87     variable.
88 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
89     special value -1 for "duration-us" argument, which will cause the
90     triggered note to be released once the original note was released.
91 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
92     - Added new API method ScriptVM::syntaxHighlighting() which provides
93     a convenient syntax highlighting backend for external instrument
94     script editor applications.
95 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
96     - Extended parser issues to provide not only first line and first
97     column, but also last line and last column of issue (thus marking
98     the precise span of the issue within the source code).
99 schoenebeck 2902 - Reload script automatically after being modified by an instrument
100     editor.
101 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
102     like "on note end on".

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

138     - Added built-in script constant "$NI_CB_TYPE_NOTE".
139     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

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

174     - Implemented built-in script function "fade_in()".
175     - Implemented built-in script function "fade_out()".
176     - Fixed acceptance of wrong data type of parameters passed to built-in
177     script functions "change_vol()", "change_tune()", "change_pan()",
178     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
179     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
180     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
181 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
182     of its possible parameter selections.
183     - Added built-in script function "set_event_par()" and implemented some
184     of its possible parameter selections.
185 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
186 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
187 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
188     built-in function "ignore_controller()".
189 schoenebeck 3214 - Implemented built-in script function "change_velo()".
190     - Implemented built-in script function "change_note()".
191 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
192     intuitive behavior if used in combination with "change_vol_time()" or
193     "change_tune_time()" respectively: now tuning/volume changes are only
194     assigned (without delay) immediately to a new note if the respective
195     timing function has not been called before, otherwise the volume/tuning
196     changes are automatically faded (before, only the event's time stamp was
197     relevant).
198 schoenebeck 3221 - Implemented built-in script function "array_equal()".
199     - Implemented built-in script function "search()".
200     - Implemented built-in script function "sort()".
201     - NKSP Fix: Never suspend "init" event handlers.
202 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
203     available for gig format engine).
204 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
205     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
206     - Implemented built-in script function "change_vol_curve()".
207     - Implemented built-in script function "change_tune_curve()".
208 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
209     offset with argument 3, where special value -1 means to use the regular
210     sample offset as defined by the instrument file.
211 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
212     - Built-in variable $EVENT_NOTE is now a read-only variable.
213     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
214     - built-in "play_note()" function now accepts -2 for its fourth argument
215     (note duration) which means the life time of the note shall be sticked
216     to the requested note number of argument 1.
217     - Fix: built-in "play_note()" function now returns 0 as result value if
218     -1 was passed for its fourth argument (note duration) and the respective
219     parent note is already gone.
220 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
221 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
222     - NKSP language: Raise parser warning if array variable is accessed with
223     an index that exceeds the array's size.

230     "init" event handlers.
231 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
232     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
233     to retrieve all code blocks filtered out by the preprocessor.
234 schoenebeck 3293 - Added built-in script function "fork()".
235     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
236     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
237     - Fixed potential crash when accessing dynamic built-in array variables.
238 schoenebeck 3296 - Added built-in script function "callback_status()".
239     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
240     - Added built-in constant $CALLBACK_STATUS_QUEUE.
241     - Added built-in constant $CALLBACK_STATUS_RUNNING.
242 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
243     "change_decay()" and "change_release()" to i.e. allow passing 2000000
244     for doubling the respective time.
245 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
246     to a lexer start condition stack underrun.
247     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
248     USE_CODE_IF_NOT() preprocessor statements.
249 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
250     can be set to disable all subsequent built-in "message()" function calls
251     on preprocessor level.
252 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
253 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
254     to avoid the editor app to crash on ill-formed text input.
255 schoenebeck 3335 - Added built-in script function "change_pan_time()".
256     - Added built-in script function "change_pan_curve()".
257 schoenebeck 2871
258 schoenebeck 3050 * Instruments DB:
259     - Fixed memory access bug of general DB access code which lead to
260     undefined behavior.
261 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
262     - The instrument DB path of linuxsampler's --create-instruments-db argument
263     is now optional, if it is missing, then a default location is used.
264 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
265     - Added support for scanning Sound Font (.sf2) files.

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

374     code is shared by all sampler engine implemementations, however only the
375     gig file format currently provides support for storing instrument scripts
376     (as LinuxSampler extension to the original GigaStudio 4 format).

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

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

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

885 persson 1748 jack_client_new
886 iliev 1829 - added (experimental) CoreAudio driver
887 persson 1888 - applied old fixes to the ASIO driver that were included in the
888     previous binary release but accidentally never committed to CVS
889     (fixes #117)
890 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
891     win64)

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

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

940 persson 1646 - made it possible to load an instrument even if the audio thread
941     isn't running
942 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
943     enough for piano gigs with pedal noise samples
944 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
945     respective FX send MIDI controller was used
946 schoenebeck 1724 - added support for GM global device volume SysEx message
947 schoenebeck 1762 (can be selected at compile time to either apply globally to the
948     whole sampler [default] or only to the sampler channels that are
949     connected to the respective MIDI input port the SysEx message arrived
950     on)
951 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
952     sometimes wrongly killed in the same buffer, causing no sound to
953     be played
954 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
955     which is usally used to switch a part between chromatic sounds and
956     drumkit sounds (as opposed to their common default setting of MIDI
957     part 10 being a drumkit part and all other ones chromatic parts), in
958     LS however one can switch between the first 16 MIDI instrument maps
959     defined for the sampler
960 persson 1764 - made it possible to create multiple sample channels even if the
961     audio thread isn't running
962 persson 1844 - fixed crash when removing channel with active voices (#116)

964     un-cache the respective sample if it's really not used by any
965     sampler engine anymore
966     - re-cache samples in case they were changed by an instrument editor,
967     e.g. when a sample was added while playing (#82)
968 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
969     same time stamp as the voice's note-on event and occured both in the
970     same audio fragment cycle (fixes bug #112)
971 persson 1858 - added support for the "fine tune" and "pitch bend range"
972     instrument-level gig parameters
973     - fixed minor artifacts in pitch bend handling
974 schoenebeck 1860 - added support for GS Reset SysEx message
975 persson 1862 - allow gig files to use unlimited downward pitch shifting
976     - added a limit check for upward pitch shifting
977 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
978     note was silent
979 persson 1923 - fixed crash happening when a pitch bend event arrived at the
980     same time a new instrument was loading
981 persson 1644
982 schoenebeck 1687 * LSCP server:
983     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
984     react on MIDI data arriving on certain sampler channels (so far only
985     Note-On and Note-Off events are sent via this LSCP event)
986 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
987     react on MIDI data arriving on certain MIDI input devices (so far only
988     Note-On and Note-Off events are sent via this LSCP event)
989 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
990     SET DB_INSTRUMENT FILE_PATH
991 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
992     frontends to send MIDI messages to specific sampler channel
993     - added two additional fields to GET FILE INSTRUMENT INFO command -
994     KEY_BINDINGS and KEYSWITCH_BINDINGS
995 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
996     was incorrect
997 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
998 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
999     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1000     be triggered respectively
1001     - added new LSCP command "SET STREAMS" to globally alter the maximum
1002     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1003     which will be triggered respectively
1004 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1005     a gigedit file dialog is opened)
1006 iliev 1848 - close all connections when LSCPServer is deleted
1007 iliev 1882 - hard close of all sockets on exit

1026 iliev 1847 - fixed crash when changing the audio output device of a sampler
1027     channel with loaded instrument and start playing notes
1028 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1029 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

1044     glibc versions (see Gentoo bug report #194076)
1045 senoner 1502 - added autoconf checks for MS Windows
1046 schoenebeck 1454
1047 persson 1455 * general changes:
1048     - bugfix: the thread used by an editor plugin didn't die when the
1049     editor closed
1050 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1051     out all the space. operator--() did not apply size_mask after
1052     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1053     order to avoid problems with the _NonVolatileReader functions.
1054     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1055     GetWriteSpace(). Since this function is currently only used in
1056     the stream's qsort() compare function, it didn't trigger any
1057     bugs.
1058     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1059     24bit mode too. Faster method to read 24bit words on little
1060     endian machines (x86): replaced 3 byte reads + shifts with a 1
1061     unaligned 32bit read and shift
1062     - experimental support for MS Windows (MIDI input via MME, AUDIO
1063     output via ASIO)
1064     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1065 iliev 1541 - support for monitoring the total number of active disk streams
1066     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1067     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1068 persson 1455
1069 senoner 1500 * AUDIO driver:
1070 persson 1534 - added Windows ASIO low latency audio driver
1071 senoner 1500
1072 senoner 1485 * MIDI driver:
1073 schoenebeck 1495 - added MME Windows MIDI driver
1074 senoner 1485
1075 schoenebeck 1471 * LSCP server:
1076     - added support for Windows style path / filenames, however with
1077     forward slash path separators instead of backslash
1078     (i.e. "C:/foo/bar.gig")
1079 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1080     apostrophes as well
1081 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1082     "LIST FILE INSTRUMENTS <file>" and
1083     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1084     about an arbitrary instrument file on the system where the sampler is
1085     running on
1086 schoenebeck 1471
1087 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1088 schoenebeck 947
1089 schoenebeck 1065 * packaging changes:
1090 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1091     API header files anymore
1092 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1093     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1094 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1095     capable to execute our autoconf environment, thus no need anymore
1096     to maintain the compile time configuration file (osx/version.h) for
1097     OSX manually (patch by Toshi Nagata)
1098 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1099     parameters
1100 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1101     C++ API header files, all implementation internal global definitions
1102     are now in global_private.h
1103     - atomic.h is not exposed to the C++ API anymore
1104     - no need to include config.h anymore for using LS's API header files
1105     - fixed warnings in API doc generation
1106 schoenebeck 1065
1107 schoenebeck 947 * general changes:
1108     - replaced the old, confusing MIDI program change mechanism by a
1109     flexible MIDI instrument mapper which allows to map arbitrary
1110 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1111 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1112     loaded on the respective channel when such MIDI program change
1113     messages arrive, beside that, each entry allows to define a life-time
1114     strategy for the instrument, so the user can define whether the
1115     instrument should i.e. be permanently loaded (to be able to switch
1116     quickly among sounds) or i.e. loaded just on demand when the
1117     respective program change arrives (to safe RAM space), as well as a
1118     global volume factor for each entry, so the user can adjust the volume
1119     dynamic of his mapped instrument collection without having to modify
1120 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1121     MIDI instrument maps and assign each sampler channel individually
1122     a certain map, so that i.e. separation of normal instruments and
1123     drumkits is possible
1124 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1125     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1126 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1127     due to a constant size RingBuffer FIFO which is now replaced by a
1128     dynamic (unlimited) size std::list FIFO
1129 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1130     output channels for being processed by external effect processors
1131     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1132     controllers
1133 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1134 iliev 1130 - Implemented new, improved notification system
1135 schoenebeck 1149 - fixed compilation errors regarding OSX
1136     (patch by Toshi Nagata)
1137 iliev 1161 - implemented instruments database
1138 iliev 1345 - added support for escape sequences to the instruments database
1139 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1140     within the sampler's process (by using instrument editor plugins),
1141     you'll notice the new "Registered instrument editors:" message on
1142 schoenebeck 1407 startup, added a new LSCP command:
1143     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1144 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1145     given sampler channel, the plugin path can be overridden at compile
1146     time with ./configure --enable-plugin-dir=/some/dir
1147 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1148     in the sampler's process to safely edit instruments while playing
1149     without a crash (hopefully) by either suspending single regions
1150     wherever possible or if unavoidable whole engine(s)
1151 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1152     policy and priority on thread level, set a minimum stack size for
1153     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1154     threads simply inherited properties of starting thread instead of
1155     setting their own policy and priority
1156 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1157     main process did not wait for the stack trace process to finish
1158     its output
1159 persson 1248 - fixed some minor memory leaks
1160 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1161     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1162 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1163     register, to avoid relocations in the text segment at runtime)
1164 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1165 schoenebeck 947
1166     * MIDI driver:
1167     - dispatch bank select (MSB and LSB) messages
1168    
1169 schoenebeck 1049 * audio driver:
1170     - the ALSA audio output driver parameters now reflect the correct
1171     parameter value ranges for the respective selected sound card
1172     (patch by Till Wimmer, a bit fixed and extended)
1173    
1174 persson 951 * Gigasampler format engine:
1175     - if a filter is used and EG2 finishes before EG1, let the voice
1176     die when EG2 has finished (this fixes a problem with clicks and
1177     voice starvation for some gigs)
1178 persson 1038 - playback is no longer disabled during instrument loading
1179     - all notes playing on a channel that changes its instrument keep
1180     playing with the old instrument until they get a note off
1181     command
1182 persson 1039 - EG fix: a release value of zero could cause noises or crash
1183 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1184 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1185     above max sustain level, which means that there is a decay phase
1186     even if sustain is 100%
1187 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1188     noises or crashes
1189 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1190 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1191     supplied to the configure script (fixes #46)
1192 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1193     instead of a fix value
1194 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1195     127 (solo mode) only kill voices if the respective mode really
1196     changed
1197 persson 951
1198 schoenebeck 1244 * LSCP server:
1199     - fixed compile time error for old Bison versions
1200     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1201 schoenebeck 1245 - parser now supports extended ASCII character set
1202     (up to ASCII code 255, i.e. includes now umlauts and accents)
1203     - filename arguments in LSCP commands now allow to use escape
1204     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1205     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1206     code value like \xf2) (fixes bug #24)
1207 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1208     least one of their text-based parameters (i.e. name, description):
1209     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1210     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1211     "SET DB_INSTRUMENT_DIRECTORY NAME",
1212     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1213     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1214     "FIND DB_INSTRUMENT_DIRECTORIES"
1215 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1216     occured, the unexpected character and the actually expected, possible
1217     character(s), the latter only if less than 5 possibilities)
1218 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1219     settings
1220 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1221     of strings were treated as being one string containing commas
1222     (fixes #57)
1223 schoenebeck 1244
1224 iliev 959 * Bug fixes:
1225     - fixed crash occurring on certain LSCP scripts (Bug 39)
1226 persson 1038 - another thread safety fix for lscp "load engine" and "set
1227     channel audio output device"
1228 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1229     on a sampler channel with connected MIDI device
1230 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1231     device connected to a sampler channel to number less then or equal
1232     to the index of the port to which the sampler channel is connected.
1233 iliev 1296 - The previous bindings were not been disconnected when altering
1234     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1235     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1236 iliev 1297 - The active stream/voice count statistic was incorrect.
1237 iliev 1298 - notification events were not been sent for some sampler
1238     channel changes
1239 iliev 1305 - added default min and max values to restrict the number of allowed
1240     audio output channels and MIDI input ports
1241 iliev 1306 - the connection to the PCM interface is now closed when destroying
1242     an audio output device
1243 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1244 iliev 959
1245 schoenebeck 1221 * test cases:
1246     - updated and fixed (haven't been touched in a while)
1247    
1248 schoenebeck 937 Version 0.4.0 (24 November 2006)
1249 persson 696
1250 schoenebeck 697 * packaging changes:
1251 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1252     to post-(un)install steps; added devel package for liblinuxsampler;
1253     to linuxsampler.spec (RPM)
1254 schoenebeck 697 - install necessary development header files for allowing 3rd party
1255     applications to link against liblinuxsampler
1256     - liblinuxsampler's API documentation can be generated with 'make docs'
1257     (Doxygen required)
1258 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1259     implementation (currently either an integer math solution or a
1260     di-harmonic approximation), automatic detection can be overriden
1261     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1262     configure script argument though (mandatory for cross-compilation)
1263 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1264     provided some on his own (as CXXFLAGS)
1265 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1266     messages
1267 schoenebeck 852 - added compile time options to allow disabling the various audio and
1268     MIDI drivers
1269 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1270     (patch by Ebrahim Mayat)
1271 schoenebeck 697
1272 persson 696 * Gigasampler format engine:
1273 schoenebeck 738 - extensive synthesis optimization
1274     (reimplementation of EGs and LFO(s), removed synthesis parameter
1275     prerendering and the synthesis parameter matrix in general, splitting
1276     each audio fragment into subfragments now where each subfragment uses
1277 persson 830 constant pitch and filter coefficients. The volume coefficient is
1278     linearly interpolated inside a subfragment, unless
1279     --disable-interpolate-volume is set.)
1280 persson 696 - fine tuning of the EG modulation parameters
1281 persson 729 - improved filter cutoff calculation by adding support for the
1282     following gig parameters: Cutoff freq (used when no cutoff
1283     controller is defined), Control invert, Minimum cutoff, Velocity
1284 persson 791 curve and Velocity range. The keyboard tracking now scales
1285     cutoff frequency instead of resonance.
1286 persson 877 - added support for gig parameter Resonance.
1287 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1288 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1289     which can be overridden with --enable-global-attenuation
1290 persson 783 - EG fixes: made the length of "attack hold" stage more
1291     accurate. Release stage can now start before attack stage
1292 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1293     time now has a minimal value to prevent clicks.
1294 persson 799 - fixed pitch changes larger than one octave
1295 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1296     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1297     all modes can be altered via standard GM messages, that is CC5 for
1298     altering portamento time, CC65 for enabling / disabling portamento
1299     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1300 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1301     parameter) and crossfade
1302 persson 831 - added support for the "attenuation controller threshold" gig
1303     parameter
1304 persson 832 - added smoothing of volume changes caused by control change
1305     messages
1306 persson 865 - sample loop parameters are now taken from the DimensionRegion
1307     instead of the wave chunk
1308     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1309     not equal to a power of two
1310 persson 877 - reimplementation of the filter algorithm. The new filter is more
1311     accurate and supports all gig filter types, including bandreject
1312     and lowpass turbo.
1313 persson 903 - real support for 24 bit samples - samples are not truncated to
1314     16 bits anymore
1315     - support for aftertouch (channel pressure, not polyphonic
1316     aftertouch)
1317 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1318     amplifying from 0)
1319 persson 696
1320 schoenebeck 711 * LSCP server:
1321     - fixed application exit on broken pipe error (fixes bug #20)
1322 iliev 793 - fixed the notification messages delay due to lack of
1323     network activity (fixes bug #26)
1324 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1325     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1326 schoenebeck 711
1327 schoenebeck 838 * audio driver:
1328     - added aRts audio output driver (by no means RT safe)
1329    
1330 schoenebeck 775 * MIDI driver:
1331     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1332     messages several times instead of once
1333 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1334     for events (i.e. for offline rendering based MIDI drivers)
1335 persson 922 - added checks for bad MIDI data
1336 schoenebeck 775
1337 schoenebeck 900 * linuxsampler application:
1338     - show available sampler engine types on startup
1339    
1340 schoenebeck 705 * general changes:
1341     - support for muting sampler channels and solo mode of the same, two new
1342     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1343     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1344     introduced for this, the behavior is the same like on a mixer console
1345 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1346     --enable-process-muted-channels which can be used to enable the
1347     processing of muted channels.
1348 iliev 777 - support for sostenuto pedal
1349 iliev 779 - support for monitoring the total number of active voices
1350 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1351     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1352 persson 835 - fixed some memory management errors
1353 persson 841 - fixed some concurrency problems that could lead to crashes when
1354     LSCP commands were executed
1355 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1356     sampler channel (fixes bug #36)
1357 schoenebeck 705
1358 schoenebeck 692 Version 0.3.3 (15 July 2005)
1359 schoenebeck 686
1360     * packaging changes:
1361     - fixed compilation with gcc 4.0
1362    
1363 schoenebeck 687 * Gigasampler format engine:
1364     - LFO preprocessing was performed even though the respective LFO was
1365     disabled by the instrument patch (minor efficiency fix)
1366 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1367     for volume ramp downs in the same fragment (needed for current voice
1368     stealing implementation) then simply inform the user with a warning
1369     about possible click sounds and reduce the volume ramp down
1370     appropriately instead of cancelling the audio device connection
1371 schoenebeck 687
1372 schoenebeck 677 Version 0.3.2 (24 June 2005)
1373 schoenebeck 609
1374     * packaging changes:
1375     - updated autotools build files to compile on OS X
1376     (conditional compilation of CoreMIDI and MidiShare drivers)
1377 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1378     './configure --disable-asm' (definitely not recommended)
1379 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1380     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1381     (due to 'dist-bzip2' automake option)
1382 schoenebeck 649
1383     * Gigasampler format engine:
1384     - support for the gig parameters for "release velocity response" curves
1385     - fine tuning of the EGADSR envelope
1386     - volume of release triggered samples now depends on note-on velocity,
1387     note length and gig parameter "release trigger decay" instead of
1388     note-off velocity.
1389 schoenebeck 663 - revised voice stealing
1390     (fixes crash and endless loop caused by voice stealing)
1391 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1392 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1393     instead of when the respective voice is actually launched
1394     (fixes undefined behavior if stolen voices belonged to a key group -
1395     this case was followed by a "killed voice survived" error message)
1396 schoenebeck 669 - fixed minor issue with null/silence samples
1397     (those stole voices even though they don't need a voice at all which
1398     resulted in "voice stealing didn't work out" messages)
1399 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1400     instrument or audio output device change
1401 schoenebeck 654
1402 schoenebeck 620 * LSCP server:
1403 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1404 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1405 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1406 schoenebeck 609
1407 schoenebeck 668 * linuxsampler application:
1408     - added command line parameters --lscp-addr and --lscp-port to override
1409     default IP address and port of LSCP server
1410    
1411 schoenebeck 579 Version 0.3.1 (24 May 2005)
1412    
1413     * initial release
