NKSP: Added standard units support for numbers and final "!" operator:

* NKSP strictness: Variable names, function names and preprocessor condition
  names must start with a regular character (a-z or A-Z); starting them with
  a digit or underscore is no longer allowed.

* NKSP parser fix: equal comparison operator "=" and not equal comparison
  operator "#" must only accept integer operands.

* NKSP language: Implemented support for standard units like Hertz, seconds,
  Bel including support for metric unit prefixes; so one can now e.g.
  conveniently use numbers in scripts like "5us" meaning "5 microseconds",
  or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
  "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).

* NKSP language: Introduced "final" operator "!" which is specifically
  intended for synthesis parameter values to denote that the synthesis
  parameter value is intended to be the "final" value for that synthesis
  parameter that should explicitly be used by the engine and thus causing
  the sampler engine to ignore all other modulation sources for the same
  synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
  variable or formula with this new "!" operator the expression is marked as
  being "final".

* Bumped version (2.1.1.svn4).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++11 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++11 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++11).
10
11 * Real-time instrument scripts:
12 - Added method ScriptVM::setExitResultEnabled() which allows to
13 explicitly enable the built-in exit() function to optionally accept
14 one function argument; the value of the passed exit() function
15 argument will then become available by calling
16 VMExecContext::exitResult() after script execution.
17 - 64 bit support for NKSP integer scripts variables (declare $foo).
18 - Variable names, function names and preprocessor condition names must start
19 with a regular character (a-z or A-Z); starting them with a digit or
20 underscore is not allowed.
21 - NKSP parser fix: equal comparison operator "=" and not equal comparison
22 operator "#" must only accept integer operands.
23 - NKSP language: Implemented support for standard units like Hertz, seconds,
24 Bel including support for metric unit prefixes; so one can now e.g.
25 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
26 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
27 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
28 - NKSP language: Introduced "final" operator "!" which is specifically
29 intended for synthesis parameter values to denote that the synthesis
30 parameter value is intended to be the "final" value for that synthesis
31 parameter that should explicitly be used by the engine and thus causing
32 the sampler engine to ignore all other modulation sources for the same
33 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
34 variable or formula with this new "!" operator the expression is marked as
35 being "final".
36
37 * test cases:
38 - Fixed compiler errors in test cases.
39 - Updated README for how to compile & run test cases.
40 - Updated test case
41 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
42 expected behaviour of the Mutex class implementation (recursive
43 mutex type).
44 - Added test cases for NKSP core language aspects and core built-in
45 functions.
46 - Fixed thread tests segfaulting on Linux.
47
48 Version 2.1.1 (27 Jul 2019)
49
50 * Real-time instrument scripts:
51 - Fixed behavior of built-in NKSP functions change_sustain(),
52 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
53 and change_cutoff_release().
54
55 * general changes:
56 - Only play release trigger samples on sustain pedal up if this behaviour
57 was explicitly requested by the instrument (otherwise only on note-off).
58 - Fixed compiler warnings.
59 - Fixed compilation error when cross-compiling to Mac.
60 - FX Sends: Provide more useful error messages on routing problems
61 (see bug #169).
62 - LSCP doc: Be more clear describing the two distinct approaches
63 of using external vs. internal effects (see bug #169).
64 - "optional" class: Fixed comparison operators.
65
66 * Gigasampler/GigaStudio format engine:
67 - Format extension: If requested by instrument then don't play release
68 trigger sample on note-off events.
69
70 * SFZ format engine:
71 - Fixed memory leak when releasing samples
72 (fixes bug #307, patch by Jacek Roszkowski)
73 - Fixed potential crash when a sample is shared by more than one region
74 (fixes bug #308, patch by Jacek Roszkowski).
75 - Opcode 'sample': Added support for built-in sample '*silence'
76 (fixes bug #310, patch by Jacek Roszkowski).
77
78 Version 2.1.0 (25 Nov 2017)
79
80 * SFZ format engine:
81 - added support for <global>, <master> and #define (patch by Alby M)
82 - Removed code duplication in SFZ file loading code.
83 - Added support for sfz extension opcode 'script' which may be used to
84 load real-time instrument script file (NKSP script language).
85 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
86 - Fixed unintended volume fade-in of voices under certain conditions.
87 - sfz parser: allow missing space between header and opcode
88
89 * Gigasampler/GigaStudio format engine:
90 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
91 cutoff settings.
92 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
93 all if an up-pitch of more than 40 semi tones was requested (I don't
94 think there is any stock gig sound that requires this behavior to
95 resemble its original sound).
96 - Added support for controlling whether the individual EGADSR stages may
97 be aborted (as LinuxSampler extension to the original GigaStudio 4
98 format).
99
100 * general changes:
101 - fixed printf type errors (mostly in debug messages)
102 - use unique_ptr instead of auto_ptr when building with C++11
103 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
104 allowing to sort data efficiently in real-time safe manner.
105 - RTList class: added methods for moving/inserting elements to arbitrary
106 position within a list.
107 - RTList class: added method fromPtr() for creating an Iterator object from
108 a raw element pointer.
109 - Attempt to partly fix resetting engine channels vs. resetting engine, an
110 overall cleanup of the Reset*(), ConnectAudioDevice(),
111 DisconnectAudioDevice() API methods would still be desirable though,
112 because the current situation is still inconsistent and error prone.
113 - Active voices are now internally grouped to "Note" objects, instead of
114 being directly assigned to a keyboard key. This allows more fine graded
115 processing of voices, which is i.e. required for certain instrument
116 script features.
117 - Fix: Release trigger voices were not spawned on sustain pedal up
118 (CC #64) events.
119 - Fix: Release trigger voices can now also distinguish correctly between
120 note-off and sustain pedal up events.
121 - All engines: Increased ramp speed of volume smoother and pan smoother
122 (while slow rate of crossfade smoother is preserved) to allow quick
123 volume and pan changes by instrument scripts for instance.
124 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
125 properly and thus were ignored for certain uses.
126 - Added new C++ API method
127 VirtualMidiDevice::SendChannelPressureToSampler().
128 - windows, 32-bit: fixed potential crashes by making sure the stack in
129 sub threads is 16-byte aligned
130 - fixed numerous compiler warnings
131 - Fixed invalid (note-on) event ID being assigned to new Note objects.
132 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
133 fixes potential undefined behavior.
134 - Fixed Note object leak when triggering notes on keys which did not
135 have a valid sample mapped (fixes bug #252).
136 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
137 - linuxsampler binary fix: option --create-instruments-db ignored
138 subsequent optional argument due to glibc's implementation oddity
139 which expects a "=" sign, but no space between them.
140
141 * packaging changes:
142 - removed unnecessary dependency to libuuid
143 (originated by libgig's usage of it)
144 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
145 auto detect whether it (sh/c)ould output its messages in color.
146 - Debian: Fixed packaging error about invalid "Source-Version"
147 substitution variable.
148 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
149 - Debian: Added build dependency to libsqlite3-dev for building
150 linuxsampler with instruments DB support.
151
152 * Real-time instrument scripts:
153 - Implemented scheduler for delayed MIDI events and for suspended scripts.
154 - Built-in script function "wait()": implemented support for function's
155 "duration-us" argument, thus scripts using this function are now
156 correctly resumed after the requested amount of microseconds.
157 - Built-in script function "play_note()": implemented support for
158 function's "duration-us" argument, thus notes triggered with this
159 argument are now correctly released after the requested amount of
160 microseconds.
161 - Fix: script events were not cleared when engine channel was reset,
162 potentially causing undefined behavior.
163 - Fixed crash which happened when trying to reference an undeclared
164 variable.
165 - Built-in script function "play_note()": Added support for passing
166 special value -1 for "duration-us" argument, which will cause the
167 triggered note to be released once the original note was released.
168 - Instrument script classes now exported with the liblinuxsampler C++ API.
169 - Added new API method ScriptVM::syntaxHighlighting() which provides
170 a convenient syntax highlighting backend for external instrument
171 script editor applications.
172 - Added new C++ API class "ScriptVMFactory".
173 - Extended parser issues to provide not only first line and first
174 column, but also last line and last column of issue (thus marking
175 the precise span of the issue within the source code).
176 - Reload script automatically after being modified by an instrument
177 editor.
178 - NKSP language grammar correction: allow empty event handler bodies
179 like "on note end on".
180 - Implemented built-in script function "change_vol()".
181 - Implemented built-in script function "change_tune()".
182 - Implemented built-in script function "change_pan()".
183 - Implemented built-in script function "change_cutoff()".
184 - Implemented built-in script function "change_reso()".
185 - Implemented built-in script function "event_status()".
186 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
187 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
188 "event_status()" function.
189 - NKSP language: Added support for bitwise operators ".or.", ".and."
190 and ".not.".
191 - NKSP language scanner: Fixed IDs matching to require at least one
192 character (i.e. when matching function names or variable names).
193 - NKSP language scanner: disabled unusued rules.
194 - Fixed behavior of play_note() and note_off() functions which must
195 be distinguished engine internally from "real" MIDI note on/off
196 events in order to avoid misbehaviors like hanging notes.
197 - Implemented built-in script variable "$KSP_TIMER".
198 - Implemented built-in script variable "$NKSP_REAL_TIMER".
199 - Implemented built-in script variable "$NKSP_PERF_TIMER".
200 - Implemented built-in script variable "$ENGINE_UPTIME".
201 - Implemented built-in script function "inc()".
202 - Implemented built-in script function "dec()".
203 - NKSP language fix: division expressions were evaluated too often.
204 - NKSP language fix: string concatenation operator was right
205 associative instead of left (to right).
206 - NKSP language correction: allow empty statements in entire language
207 (i.e. "if end if").
208 - Implemented built-in script function "stop_wait()".
209 - Implemented built-in script variable "$NI_CALLBACK_ID".
210 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
211 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
212 - Added support for read-only built-in variables (respectively
213 handled by the script parser).
214 - Added built-in script constant "$NI_CB_TYPE_INIT".
215 - Added built-in script constant "$NI_CB_TYPE_NOTE".
216 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
217 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
218 - NKSP Language: Added support for user defined script functions.
219 - Implemented built-in script function "change_attack()".
220 - Implemented built-in script function "change_decay()".
221 - Implemented built-in script function "change_release()".
222 - Fixed all change_*() built-in script functions to apply their
223 synthesis parameter changes immediately in case the respective note
224 was triggered at the same time, instead of scheduling the parameter
225 change, especially because it would cause some parameter types's
226 changes either to be ramped (i.e. change_vol()) or other types even
227 to have not effect at all (i.e. change_attack()).
228 - Implemented built-in script function "sh_left()".
229 - Implemented built-in script function "sh_right()".
230 - Implemented built-in script function "min()".
231 - Implemented built-in script function "max()".
232 - NKSP Fix: "init" event handler was not always executed when a script
233 was loaded.
234 - NKSP built-in wait() script function: abort script execution if
235 a negative or zero wait time was passed as argument (since this is
236 a common indication of a bug either of the script or even of the
237 engine, which could lead to RT instability or even worse).
238 - ScriptVM: Implemented automatic suspension of RT safety
239 threatening scripts.
240 - Provide more user friendly error messages on syntax errors.
241 - Fixed NKSP parser warning "Not a statement" when assigning an
242 initializer list to an array variable.

244 - Implemented built-in script function "in_range()".
245 - Implemented built-in script function "change_amp_lfo_depth()".
246 - Implemented built-in script function "change_amp_lfo_freq()".
247 - Implemented built-in script function "change_pitch_lfo_depth()".
248 - Implemented built-in script function "change_pitch_lfo_freq()".
249 - Implemented built-in script function "change_vol_time()".
250 - Implemented built-in script function "change_tune_time()".
251 - Implemented built-in script function "fade_in()".
252 - Implemented built-in script function "fade_out()".
253 - Fixed acceptance of wrong data type of parameters passed to built-in
254 script functions "change_vol()", "change_tune()", "change_pan()",
255 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
256 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
257 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
258 - Added built-in script function "get_event_par()" and implemented some
259 of its possible parameter selections.
260 - Added built-in script function "set_event_par()" and implemented some
261 of its possible parameter selections.
262 - Fixed a bunch of scheduler time related bugs.
263 - Fixed polyphonic variables not being reset to zero after usage.
264 - Built-in "ignore_event()" function: argument is now optional, like with
265 built-in function "ignore_controller()".
266 - Implemented built-in script function "change_velo()".
267 - Implemented built-in script function "change_note()".
268 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
269 intuitive behavior if used in combination with "change_vol_time()" or
270 "change_tune_time()" respectively: now tuning/volume changes are only
271 assigned (without delay) immediately to a new note if the respective
272 timing function has not been called before, otherwise the volume/tuning
273 changes are automatically faded (before, only the event's time stamp was
274 relevant).
275 - Implemented built-in script function "array_equal()".
276 - Implemented built-in script function "search()".
277 - Implemented built-in script function "sort()".
278 - NKSP Fix: Never suspend "init" event handlers.
279 - Implemented built-in script function "same_region()" (currently only
280 available for gig format engine).
281 - Added built-in script constant "$NKSP_LINEAR".
282 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
283 - Implemented built-in script function "change_vol_curve()".
284 - Implemented built-in script function "change_tune_curve()".
285 - built-in "play_note()" function now supports a sample playback start
286 offset with argument 3, where special value -1 means to use the regular
287 sample offset as defined by the instrument file.
288 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
289 - Built-in variable $EVENT_NOTE is now a read-only variable.
290 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
291 - built-in "play_note()" function now accepts -2 for its fourth argument
292 (note duration) which means the life time of the note shall be sticked
293 to the requested note number of argument 1.
294 - Fix: built-in "play_note()" function now returns 0 as result value if
295 -1 was passed for its fourth argument (note duration) and the respective
296 parent note is already gone.
297 - Implemented built-in script function "change_play_pos()".
298 - NKSP language: Added support for user declared const array variables.
299 - NKSP language: Raise parser warning if array variable is accessed with
300 an index that exceeds the array's size.
301 - NKSP language fix: Unknown characters were not handled correctly.
302 - NKSP language: Added support for "synchronized .. end synchronized"
303 code blocks.
304 - Implemented built-in script function "abort()" which allows to abort
305 another script handler by passing its callback ID.
306 - Fixed potential memory access bug and potential undefined behavior of
307 "init" event handlers.
308 - Print a time stamp along to each call of built-in function "message()".
309 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
310 to retrieve all code blocks filtered out by the preprocessor.
311 - Added built-in script function "fork()".
312 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
313 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
314 - Fixed potential crash when accessing dynamic built-in array variables.
315 - Added built-in script function "callback_status()".
316 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
317 - Added built-in constant $CALLBACK_STATUS_QUEUE.
318 - Added built-in constant $CALLBACK_STATUS_RUNNING.
319 - Removed max. value limitation of built-in functions "change_attack()",
320 "change_decay()" and "change_release()" to i.e. allow passing 2000000
321 for doubling the respective time.
322 - NKSP script editor syntax highlighting API: Fixed app termination due
323 to a lexer start condition stack underrun.
324 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
325 USE_CODE_IF_NOT() preprocessor statements.
326 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
327 can be set to disable all subsequent built-in "message()" function calls
328 on preprocessor level.
329 - Implemented built-in script function "change_sustain()".
330 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
331 to avoid the editor app to crash on ill-formed text input.
332 - Added built-in script function "change_pan_time()".
333 - Added built-in script function "change_pan_curve()".
334 - Added built-in script function "change_cutoff_attack()".
335 - Added built-in script function "change_cutoff_decay()".
336 - Added built-in script function "change_cutoff_sustain()".

338 - Added built-in script function "change_cutoff_lfo_depth()".
339 - Added built-in script function "change_cutoff_lfo_freq()".
340
341 * Instruments DB:
342 - Fixed memory access bug of general DB access code which lead to
343 undefined behavior.
344 - Cleanup of instruments DB file creation and opening code.
345 - The instrument DB path of linuxsampler's --create-instruments-db argument
346 is now optional, if it is missing, then a default location is used.
347 - Added support for scanning SFZ (.sfz) files.
348 - Added support for scanning Sound Font (.sf2) files.
349 - Fixed undefined DB transaction behavior.
350

383 on the process's main thread
384 - fixed build error on newer MinGW
385 - support building with older jack versions
386 - support building with spaces in vst sdk path
387 - enabled automake 'subdir-objects' option and moved external

389 in order to get rid of warnings from automake 1.14
390
391 * general changes:
392 - Refactoring: moved the independent code from
393 the Gigasampler format engine to base classes
394 - command line option '--profile' is currently disabled, since the
395 respective profiling code is currently broken
396 - Introduced support for optional environment variable
397 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
398 where the sampler shall look for instrument editor plugins
399 (patch by Luis Garrido, slightly modified).
400 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
401 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
402 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
403 note (in this implementation of the sampler its simply hard routed to
404 the 1st effect send of the sampler channel, no matter what the actual
405 effect type is)
406 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
407 note (in this implementation of the sampler its simply hard routed to
408 the 2nd effect send of the sampler channel, no matter what the actual
409 effect type is)
410 - implemented support for internal LADSPA effects
411 - raised limit of program change queue from 100 to 512
412 (as suggested by Alex Stone)
413 - implemented sine LFO, pulse LFO and saw LFO
414 - experimental support for per voice equalization
415 - added command line option --exec-after-init
416 - Introduced new C++ API method:
417 EngineChannel::InstrumentFileName(int index)
418 allowing to retrieve the whole list of files used for the loaded
419 instrument on an engine channel (a.k.a. part). Some GigaStudio
420 instruments for example are splitted over several files like
421 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
422 - Added new C++ API method Sampler::GetGlobalMaxVoices().
423 - Added new C++ API method Sampler::GetGlobalMaxStreams().
424 - Added new C++ API method Sampler::SetGlobalMaxVoices().
425 - Added new C++ API method Sampler::SetGlobalMaxStreams().
426 - Various "const" and "restrict" optimizations.
427 - all engines: add pan CC value to instrument pan parameter before
428 applying panning, instead of using two separate pan functions in
429 series (#182)
430 - added a lock guard class for exception safe mutex handling and
431 used it everywhere appropriate
432 - Immediately apply scale tuning changes to active voices.
433 - Exposed scale tuning to C++ API (along to the already existing standard
434 SysEx way).
435 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
436 and broken for ppc64. (Seq_cst loads and stores are actually not
437 used in LS, so the bug wasn't noticable.)
438 - lsatomic.h: added ARMv7 support
439 - Added support for multiple MIDI input ports per sampler channel (and
440 added various new C++ methods for this new feature / design change, old
441 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
442 as deprecated but are still there and should provide full behavior
443 backward compatibility).
444 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
445 unsafe and caused compilation error with clang 2.x).
446 - Bugfix: only process the latest MIDI program change event.
447 - Introducing the LSCP shell, which provides convenient control of the
448 sampler from the command line by providing LSCP aware features.
449 - VirtualMidiDevice: Added support for program change.
450 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
451 - VirtualMidiDevice: Added support for pitch bend.
452 - Aftertouch: extended API to explicitly handle channel pressure and
453 polyphonic key pressure events (so far polyphonic pressure was not
454 supported at all, and channel pressure was rerouted as CC128 but not
455 used so far).
456 - Added initial support for real-time instrument scripts. The script VM
457 code is shared by all sampler engine implemementations, however only the
458 gig file format currently provides support for storing instrument scripts
459 (as LinuxSampler extension to the original GigaStudio 4 format).

837 handler to "release" event handler.
838 - Fixed crash when using built-in script function "by_marks()".
839
840 * Bug fixes:
841 - Fixed crash which may occur when MIDI key + transpose is out of range
842 - minor valgrind fixes
843 - fixed crash which occurred when changing an already deployed sampler
844 channel to a different engine type
845 - fixed crash when deleting a sampler channel or changing engine
846 type while an instrument load was in progress
847 - bugfix: playing a note while changing the instrument could cause
848 a crash, or give "Handing back unknown region" error messages
849 - bugfix: calling SET VOICES (which Fantasia does on start and
850 refresh) could cause instruments to be unloaded
851 - Mac OS X: fixed name collision of enum in EffectControl and
852 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
853 - Mac OS X: fixed hanging threads
854 - Windows: disabled the previous thread fix on non-Mac systems, as
855 it caused hanging threads on Windows
856 - Fixed possible crashes due to corrupted MIDI/audio device list
857 after MIDI/audio device creation failure
858 - When creating MIDI instrument map entries with "PERSISTENT" type, the
859 instruments were uselessly precached with zero samples, however it still
860 took the full preloading time and on 1st program change the respective
861 instrument was completely reloaded again.
862 - fixed handling of rapid bank select and program change messages
863 sent to the same sampler channel (patch from the Open Octave
864 project, slightly adjusted)
865 - fixed crash when trying to create an effect instance with controls
866 which min and/or max values depend on the sample rate
867 - fixed bug #162
868 - bugfix: LADSPA_PATH was not evaluated correctly when containing
869 multiple paths (#165)
870 - thread safety fixes for the instrument loading thread
871 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
872 (#176)
873 - more thread safety fixes for the instrument loading thread
874 - sfz/sf2 engine: fixed crash when using small audio fragment size
875 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
876 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
877 introduced in previous fix)
878 - fixed crash when a channel received a program change while
879 playing a note in a key group
880 - fixed erroneous error message piping in VoiceBase.h
881 (labelled "Disk stream not available in time")
882 - Update effects on sample rate & period size changes (to avoid
883 crashes and noise on such transitions).
884 - ignore missing LADSPA paths without ignoring valid LADSPA paths
885 (fixes #208)
886 - Fixed bug in LSCP grammar definition which caused a statement like
887 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
888 practically irrelevant, however it caused problems with the new LSCP
889 shell's auto completion feature).
890 - Fixed MIDI program change messages being ignored if quickly executed
891 after each other (fixes #231).
892
893 Version 1.0.0 (31 July 2009)
894
895 * packaging changes:
896 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
897 causing e.g. the libgig test to fail when
898 "./configure --disable-jack-driver" was used
899 (patch by Alexis Ballier)
900 - fixed compilation with gcc 4.3
901 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
902 - fixed configure so it detects x86_64 (#107)
903 - fixes for building with newer MinGW versions
904 - fix for building with bison 2.4 (#111)
905 - fixed building with libgig installed in a non-standard directory
906 - minor fix in configure for mmsystem.h detection on MinGW
907 - Windows: look for editor plugins and Fantasia using base
908 directory of liblinuxsampler dll (look in the same directory and one
909 directory above)
910 - configure script fix: removed unconditional use of SSE
911 - fixed building with sqlite installed in a non-standard directory
912 - when cross-compiling, don't try to create instruments.db
913 - fix for new mingw-w64 version, which has usleep
914
915 * general changes:
916 - bugfix: on some POSIX systems instrument editor plugins refused to
917 load as we used a non-portable Linux specific struct field
918 (fixes bug #70, patch by Ronald Baljeu)
919 - fixed endless loop which occured when loading an instrument editor
920 plugin DLL on Windows systems failed
921 - fixed memory leaks that occurred when liblinuxsampler was unloaded
922 - optimized the SynchronizedConfig class so it doesn't wait
923 unnecessarily long after an update
924 - added support for notifying instrument editors on note-on / note-off
925 events (e.g. to highlight the pressed keys on the virtual keyboard
926 of gigedit)
927 - added support for triggering notes by instrument editors (see above)
928 - be verbose on DLL load errors (on Linux)
929 - fixed di-harmonic triangle LFO implementation (this LFO implementation
930 is only used by very few systems, most pick the int math
931 implementation, which is usually faster)
932 - fixes for audio drivers with varying buffer sizes
933 - experimental support for running LinuxSampler as a DSSI, LV2 and
934 VST plugin
935 - notification events for stream/voice count statistics are now sent
936 only when there are actual changes
937 - added memory ordering constraints to improve stability on
938 multi-core and multi-cpu systems
939 - maximum voices and disk streams can now be altered at runtime
940 - fixed CPU feature detection on x86_64 (maybe fixes #108)
941 - automatic stacktrace mechanism is now turned off by default and can
942 be switched on by command line option "--stacktrace" (the automatic
943 stacktrace mechanism seems to be broken on most systems at the moment)
944 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
945 a pointer to the launched InstrumentEditor object
946 - added optional 3rd party user data parameter for following
947 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
948 InstrumentEditor::Launch(),
949 InstrumentManager::LaunchInstrumentEditor()
950 - theoretical fix: made SynchronizedConfig follow C++0x memory
951 model more strictly
952 - fixes for using large audio device buffers
953 - Windows: add the installation directory to the DLL search path
954 when loading an editor plugin (solves problems with VST and
955 gigedit on systems with other GTK versions installed)
956 - updated linuxsampler man page
957
958 * audio driver:
959 - removed the nonsense audio channel constraint (which was hard coded to
960 max. 100 audio channels) for most audio drivers
961 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
962 opposed to the LSCP specs
963 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
964 reflected the wrong value
965 - fixed a memory management bug in ASIO driver
966 - Makefile fix: JACK_CFLAGS wasn't used
967 - JACK: use jack_client_open instead of the deprecated
968 jack_client_new
969 - added (experimental) CoreAudio driver
970 - applied old fixes to the ASIO driver that were included in the
971 previous binary release but accidentally never committed to CVS
972 (fixes #117)
973 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
974 win64)
975 - VST: added support for sample rate and buffer size changes
976 - VST: close editor (Fantasia) when the VST is removed
977 - VST: avoid opening Fantasia more than once for each VST instance
978 - VST: export main function as "main" on Linux too (fix for
979 energyXT)
980 - VST: changed number of output channels from one stereo to 16
981 stereo
982 - added channel routing, fxsends and midi maps to the settings
983 stored in the plugin state
984 - performance optimization of AudioChannel::MixTo() and
985 AudioChannel::CopyTo() methods using GCC vector exensions
986 (if available)
987 - ASIO fixes: avoid initializing the device twice, avoid throwing
988 exception when getting parameters from a disconnected device
989
990 * MIDI driver:
991 - added JACK MIDI driver
992 - dispatch bank select as ordinary CC as well, the user might seriously
993 want to (mis)use it for some purpose ("fixed" in all current MIDI
994 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
995 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
996 CoreMidi or AU
997 - fixed mingw-w64 compilation error in MME driver
998 - made program change handling in MIDI thread real-time safe by
999 moving the logic to a non-RT thread
1000 - fixed minor memory leak in ALSA driver
1001
1002 * instruments database:
1003 - avoid time consuming samples scanning when adding instruments
1004 to the instruments database
1005 - added support for handling lost files in the instruments database
1006 - Implemented option for adding instruments in separate directories
1007 in the instruments database
1008 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1009 - work-around for missing fnmatch function on Windows to make
1010 instrument database compilable
1011 - added instrument database support on Windows
1012 works with both standalone mode and VST plugin.
1013 the instruments DB file is located in
1014 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1015 databases for each windows user
1016 if no DB is present it automatically creates the .linuxsampler subdir
1017 and then creates an empty DB
1018 - fixed recursive import, which was broken on Windows
1019
1020 * Gigasampler format engine:
1021 - fixed a memory leak that could happen when a channel was deleted
1022 while notes were playing
1023 - made it possible to load an instrument even if the audio thread
1024 isn't running
1025 - added partial support for the "Controller Triggered" MIDI rule,
1026 enough for piano gigs with pedal noise samples
1027 - minor fix: only mark FX sends as being modified if really the
1028 respective FX send MIDI controller was used
1029 - added support for GM global device volume SysEx message
1030 (can be selected at compile time to either apply globally to the
1031 whole sampler [default] or only to the sampler channels that are
1032 connected to the respective MIDI input port the SysEx message arrived
1033 on)
1034 - bugfix: notes triggered at position 0 in the audio buffer were
1035 sometimes wrongly killed in the same buffer, causing no sound to
1036 be played
1037 - added support for chromatic / drumkit mode Roland GS Sysex message
1038 which is usally used to switch a part between chromatic sounds and
1039 drumkit sounds (as opposed to their common default setting of MIDI
1040 part 10 being a drumkit part and all other ones chromatic parts), in
1041 LS however one can switch between the first 16 MIDI instrument maps
1042 defined for the sampler
1043 - made it possible to create multiple sample channels even if the
1044 audio thread isn't running
1045 - fixed crash when removing channel with active voices (#116)
1046 - bugfix: on sample reference changes (instrument editor), only
1047 un-cache the respective sample if it's really not used by any
1048 sampler engine anymore
1049 - re-cache samples in case they were changed by an instrument editor,
1050 e.g. when a sample was added while playing (#82)
1051 - fixed hanging notes which occured when note-off event had the exact
1052 same time stamp as the voice's note-on event and occured both in the
1053 same audio fragment cycle (fixes bug #112)
1054 - added support for the "fine tune" and "pitch bend range"
1055 instrument-level gig parameters
1056 - fixed minor artifacts in pitch bend handling
1057 - added support for GS Reset SysEx message
1058 - allow gig files to use unlimited downward pitch shifting
1059 - added a limit check for upward pitch shifting
1060 - bugfix: sometimes, when playing a note twice fast, the second
1061 note was silent
1062 - fixed crash happening when a pitch bend event arrived at the
1063 same time a new instrument was loading
1064
1065 * LSCP server:
1066 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1067 react on MIDI data arriving on certain sampler channels (so far only
1068 Note-On and Note-Off events are sent via this LSCP event)
1069 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1070 react on MIDI data arriving on certain MIDI input devices (so far only
1071 Note-On and Note-Off events are sent via this LSCP event)
1072 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1073 SET DB_INSTRUMENT FILE_PATH
1074 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1075 frontends to send MIDI messages to specific sampler channel
1076 - added two additional fields to GET FILE INSTRUMENT INFO command -
1077 KEY_BINDINGS and KEYSWITCH_BINDINGS
1078 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1079 was incorrect
1080 - Optimized the retrieval of the MIDI instrument mappings
1081 - added new LSCP command "SET VOICES" to globally alter the maximum
1082 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1083 be triggered respectively
1084 - added new LSCP command "SET STREAMS" to globally alter the maximum
1085 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1086 which will be triggered respectively
1087 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1088 a gigedit file dialog is opened)
1089 - close all connections when LSCPServer is deleted
1090 - hard close of all sockets on exit
1091 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1092 driver
1093
1094 * Bug fixes:
1095 - fixed a crash which occurs when removing a sampler channel waiting
1096 to start instrument loading after another channel
1097 - fixed a crash which occurs when removing a sampler channel with
1098 instrument loading in progress (bug #113)
1099 - fixed termination caused by uncaught exception when adding MIDI
1100 instrument with PERSISTENT load mode
1101 - fixed possible iterator invalidations when resetting the sampler
1102 - fixed memory leaks when issuing the following LSCP commands:
1103 GET AUDIO_OUTPUT_DRIVER INFO
1104 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1105 GET MIDI_INPUT_DRIVER INFO
1106 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1107 - fixed possible compilation error when sqlite is not present
1108 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1109 - fixed crash when changing the audio output device of a sampler
1110 channel with loaded instrument and start playing notes
1111 - fixed endless loop in Engine::SuspendAll() (bug #120)
1112 - fixed a low-level atomic load function that was broken on 64-bit
1113 PowerPC, which probably could cause crashes on that platform
1114 - fixed a memory management error which could cause a crash when a
1115 plugin was unloaded
1116 - bugfix: two private structs had the same name, which could cause
1117 problems if the linker chose the wrong constructor
1118 - fixed low-level ConditionServer usage bug that caused lockups on
1119 Windows
1120
1121
1122 Version 0.5.1 (6 December 2007)
1123
1124 * packaging changes:
1125 - added autoconf checks for pthread library
1126 - added autoconf check for pthread bug found on certain NPTL-enabled
1127 glibc versions (see Gentoo bug report #194076)
1128 - added autoconf checks for MS Windows
1129
1130 * general changes:
1131 - bugfix: the thread used by an editor plugin didn't die when the
1132 editor closed
1133 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1134 out all the space. operator--() did not apply size_mask after
1135 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1136 order to avoid problems with the _NonVolatileReader functions.
1137 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1138 GetWriteSpace(). Since this function is currently only used in
1139 the stream's qsort() compare function, it didn't trigger any
1140 bugs.
1141 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1142 24bit mode too. Faster method to read 24bit words on little
1143 endian machines (x86): replaced 3 byte reads + shifts with a 1
1144 unaligned 32bit read and shift
1145 - experimental support for MS Windows (MIDI input via MME, AUDIO
1146 output via ASIO)
1147 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1148 - support for monitoring the total number of active disk streams
1149 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1150 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1151
1152 * AUDIO driver:
1153 - added Windows ASIO low latency audio driver
1154
1155 * MIDI driver:
1156 - added MME Windows MIDI driver
1157
1158 * LSCP server:
1159 - added support for Windows style path / filenames, however with
1160 forward slash path separators instead of backslash
1161 (i.e. "C:/foo/bar.gig")
1162 - allow naughty liblscp to send non-string device parameters within
1163 apostrophes as well
1164 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1165 "LIST FILE INSTRUMENTS <file>" and
1166 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1167 about an arbitrary instrument file on the system where the sampler is
1168 running on
1169
1170 Version 0.5.0 (15 October 2007)
1171
1172 * packaging changes:
1173 - config.h is not going to be installed along with liblinuxsampler's
1174 API header files anymore
1175 - only the API relevant header (and source) files will be exported to
1176 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1177 - added completely new XCode project files for Mac OSX which is now
1178 capable to execute our autoconf environment, thus no need anymore
1179 to maintain the compile time configuration file (osx/version.h) for
1180 OSX manually (patch by Toshi Nagata)
1181 - fixed buggy boolean --enable-foo / --disable-foo configure script
1182 parameters
1183 - global.h now only covers global definitions that are needed for the
1184 C++ API header files, all implementation internal global definitions
1185 are now in global_private.h
1186 - atomic.h is not exposed to the C++ API anymore
1187 - no need to include config.h anymore for using LS's API header files
1188 - fixed warnings in API doc generation
1189
1190 * general changes:
1191 - replaced the old, confusing MIDI program change mechanism by a
1192 flexible MIDI instrument mapper which allows to map arbitrary
1193 (MIDI bank, MIDI program) pairs with arbitrary
1194 (engine type, instrument file, file index) triplets which will be
1195 loaded on the respective channel when such MIDI program change
1196 messages arrive, beside that, each entry allows to define a life-time
1197 strategy for the instrument, so the user can define whether the
1198 instrument should i.e. be permanently loaded (to be able to switch
1199 quickly among sounds) or i.e. loaded just on demand when the
1200 respective program change arrives (to safe RAM space), as well as a
1201 global volume factor for each entry, so the user can adjust the volume
1202 dynamic of his mapped instrument collection without having to modify
1203 the instrument files, also one can manage arbitrary amount of such
1204 MIDI instrument maps and assign each sampler channel individually
1205 a certain map, so that i.e. separation of normal instruments and
1206 drumkits is possible
1207 - new notification events for tracking changes to audio/MIDI devices,
1208 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1209 - sampler was limited to load max. 200 instruments in the background
1210 due to a constant size RingBuffer FIFO which is now replaced by a
1211 dynamic (unlimited) size std::list FIFO
1212 - added FX sends, these allow to route audio signals to arbitrary audio
1213 output channels for being processed by external effect processors
1214 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1215 controllers
1216 - global (sampler wide) volume can now be controlled at runtime
1217 - Implemented new, improved notification system
1218 - fixed compilation errors regarding OSX
1219 (patch by Toshi Nagata)
1220 - implemented instruments database
1221 - added support for escape sequences to the instruments database
1222 - added highly experimental support for on-the-fly instrument editing
1223 within the sampler's process (by using instrument editor plugins),
1224 you'll notice the new "Registered instrument editors:" message on
1225 startup, added a new LSCP command:
1226 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1227 to spawn a matching instrument editor for the instrument on the
1228 given sampler channel, the plugin path can be overridden at compile
1229 time with ./configure --enable-plugin-dir=/some/dir
1230 - added experimental code for synchronizing instrument editors hosted
1231 in the sampler's process to safely edit instruments while playing
1232 without a crash (hopefully) by either suspending single regions
1233 wherever possible or if unavoidable whole engine(s)
1234 - fixed several issues in fundamental "Thread" class: set scheduling
1235 policy and priority on thread level, set a minimum stack size for
1236 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1237 threads simply inherited properties of starting thread instead of
1238 setting their own policy and priority
1239 - minor fix in our automatic stack trace mechanism on crashes, the
1240 main process did not wait for the stack trace process to finish
1241 its output
1242 - fixed some minor memory leaks
1243 - reenabled assembly features support, at the moment only for
1244 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1245 - minor assembly fix in x86 features detection (don't use the PIC
1246 register, to avoid relocations in the text segment at runtime)
1247 - POSIX callback functions of Thread.h are hidden
1248
1249 * MIDI driver:
1250 - dispatch bank select (MSB and LSB) messages
1251
1252 * audio driver:
1253 - the ALSA audio output driver parameters now reflect the correct
1254 parameter value ranges for the respective selected sound card
1255 (patch by Till Wimmer, a bit fixed and extended)
1256
1257 * Gigasampler format engine:
1258 - if a filter is used and EG2 finishes before EG1, let the voice
1259 die when EG2 has finished (this fixes a problem with clicks and
1260 voice starvation for some gigs)
1261 - playback is no longer disabled during instrument loading
1262 - all notes playing on a channel that changes its instrument keep
1263 playing with the old instrument until they get a note off
1264 command
1265 - EG fix: a release value of zero could cause noises or crash
1266 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1267 - EG fine tuning: when attack is zero the EG starts at a level
1268 above max sustain level, which means that there is a decay phase
1269 even if sustain is 100%
1270 - more EG fixes: the level could sometimes go below zero and cause
1271 noises or crashes
1272 - minor fix of EGDecay (patch by Toshi Nagata)
1273 - fixed compiler error when --enable-override-filter-type was
1274 supplied to the configure script (fixes #46)
1275 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1276 instead of a fix value
1277 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1278 127 (solo mode) only kill voices if the respective mode really
1279 changed
1280
1281 * LSCP server:
1282 - fixed compile time error for old Bison versions
1283 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1284 - parser now supports extended ASCII character set
1285 (up to ASCII code 255, i.e. includes now umlauts and accents)
1286 - filename arguments in LSCP commands now allow to use escape
1287 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1288 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1289 code value like \xf2) (fixes bug #24)
1290 - the following LSCP commands now also support escape sequences for at
1291 least one of their text-based parameters (i.e. name, description):
1292 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1293 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1294 "SET DB_INSTRUMENT_DIRECTORY NAME",
1295 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1296 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1297 "FIND DB_INSTRUMENT_DIRECTORIES"
1298 - returns verbose syntax errors (line and column where syntax error
1299 occured, the unexpected character and the actually expected, possible
1300 character(s), the latter only if less than 5 possibilities)
1301 - made sure that LSCP syntax is not affected by gigedit locale
1302 settings
1303 - bugfix regarding strings parameter lists: all comma separated lists
1304 of strings were treated as being one string containing commas
1305 (fixes #57)
1306
1307 * Bug fixes:
1308 - fixed crash occurring on certain LSCP scripts (Bug 39)
1309 - another thread safety fix for lscp "load engine" and "set
1310 channel audio output device"
1311 - fixed a crash which occurs when reassigning the same engine
1312 on a sampler channel with connected MIDI device
1313 - fixed a crash which occurs when changing the number of ports of a MIDI
1314 device connected to a sampler channel to number less then or equal
1315 to the index of the port to which the sampler channel is connected.
1316 - The previous bindings were not been disconnected when altering
1317 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1318 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1319 - The active stream/voice count statistic was incorrect.
1320 - notification events were not been sent for some sampler
1321 channel changes
1322 - added default min and max values to restrict the number of allowed
1323 audio output channels and MIDI input ports
1324 - the connection to the PCM interface is now closed when destroying
1325 an audio output device
1326 - files with slash in their path or filename could not be loaded
1327
1328 * test cases:
1329 - updated and fixed (haven't been touched in a while)
1330
1331 Version 0.4.0 (24 November 2006)
1332
1333 * packaging changes:
1334 - changed deprecated copyright attribute to license; added ldconfig
1335 to post-(un)install steps; added devel package for liblinuxsampler;
1336 to linuxsampler.spec (RPM)
1337 - install necessary development header files for allowing 3rd party
1338 applications to link against liblinuxsampler
1339 - liblinuxsampler's API documentation can be generated with 'make docs'
1340 (Doxygen required)
1341 - added benchmark to automatically detect the best triangle LFO
1342 implementation (currently either an integer math solution or a
1343 di-harmonic approximation), automatic detection can be overriden
1344 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1345 configure script argument though (mandatory for cross-compilation)
1346 - do not automatically pick optimized gcc flags if the user already
1347 provided some on his own (as CXXFLAGS)
1348 - added compile time option to disable processing of All-Notes-Off MIDI
1349 messages
1350 - added compile time options to allow disabling the various audio and
1351 MIDI drivers
1352 - fixed automatic GCC CPU switch detection on PPC
1353 (patch by Ebrahim Mayat)
1354
1355 * Gigasampler format engine:
1356 - extensive synthesis optimization
1357 (reimplementation of EGs and LFO(s), removed synthesis parameter
1358 prerendering and the synthesis parameter matrix in general, splitting
1359 each audio fragment into subfragments now where each subfragment uses
1360 constant pitch and filter coefficients. The volume coefficient is
1361 linearly interpolated inside a subfragment, unless
1362 --disable-interpolate-volume is set.)
1363 - fine tuning of the EG modulation parameters
1364 - improved filter cutoff calculation by adding support for the
1365 following gig parameters: Cutoff freq (used when no cutoff
1366 controller is defined), Control invert, Minimum cutoff, Velocity
1367 curve and Velocity range. The keyboard tracking now scales
1368 cutoff frequency instead of resonance.
1369 - added support for gig parameter Resonance.
1370 - fixed bug in sysex handling (patch by Juan Linietsky)
1371 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1372 which can be overridden with --enable-global-attenuation
1373 - EG fixes: made the length of "attack hold" stage more
1374 accurate. Release stage can now start before attack stage
1375 ends. Cancel release didn't work when sustain was zero. Attack
1376 time now has a minimal value to prevent clicks.
1377 - fixed pitch changes larger than one octave
1378 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1379 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1380 all modes can be altered via standard GM messages, that is CC5 for
1381 altering portamento time, CC65 for enabling / disabling portamento
1382 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1383 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1384 parameter) and crossfade
1385 - added support for the "attenuation controller threshold" gig
1386 parameter
1387 - added smoothing of volume changes caused by control change
1388 messages
1389 - sample loop parameters are now taken from the DimensionRegion
1390 instead of the wave chunk
1391 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1392 not equal to a power of two
1393 - reimplementation of the filter algorithm. The new filter is more
1394 accurate and supports all gig filter types, including bandreject
1395 and lowpass turbo.
1396 - real support for 24 bit samples - samples are not truncated to
1397 16 bits anymore
1398 - support for aftertouch (channel pressure, not polyphonic
1399 aftertouch)
1400 - LFO1 behaviour fixed (dampening from max volume instead of
1401 amplifying from 0)
1402
1403 * LSCP server:
1404 - fixed application exit on broken pipe error (fixes bug #20)
1405 - fixed the notification messages delay due to lack of
1406 network activity (fixes bug #26)
1407 - fixed parser bug which occured on space(s) within device parameters
1408 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1409
1410 * audio driver:
1411 - added aRts audio output driver (by no means RT safe)
1412
1413 * MIDI driver:
1414 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1415 messages several times instead of once
1416 - API extension for MIDI drivers which already supply exact time stamps
1417 for events (i.e. for offline rendering based MIDI drivers)
1418 - added checks for bad MIDI data
1419
1420 * linuxsampler application:
1421 - show available sampler engine types on startup
1422
1423 * general changes:
1424 - support for muting sampler channels and solo mode of the same, two new
1425 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1426 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1427 introduced for this, the behavior is the same like on a mixer console
1428 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1429 --enable-process-muted-channels which can be used to enable the
1430 processing of muted channels.
1431 - support for sostenuto pedal
1432 - support for monitoring the total number of active voices
1433 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1434 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1435 - fixed some memory management errors
1436 - fixed some concurrency problems that could lead to crashes when
1437 LSCP commands were executed
1438 - fixed crash when instrument loading failed previously on the same
1439 sampler channel (fixes bug #36)
1440
1441 Version 0.3.3 (15 July 2005)
1442
1443 * packaging changes:
1444 - fixed compilation with gcc 4.0
1445
1446 * Gigasampler format engine:
1447 - LFO preprocessing was performed even though the respective LFO was
1448 disabled by the instrument patch (minor efficiency fix)
1449 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1450 for volume ramp downs in the same fragment (needed for current voice
1451 stealing implementation) then simply inform the user with a warning
1452 about possible click sounds and reduce the volume ramp down
1453 appropriately instead of cancelling the audio device connection
1454
1455 Version 0.3.2 (24 June 2005)
1456
1457 * packaging changes:
1458 - updated autotools build files to compile on OS X
1459 (conditional compilation of CoreMIDI and MidiShare drivers)
1460 - hand-crafted assembly optimization code can be disabled with
1461 './configure --disable-asm' (definitely not recommended)
1462 - fixed 'make dist' rule to include all necessary files
1463 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1464 (due to 'dist-bzip2' automake option)
1465
1466 * Gigasampler format engine:
1467 - support for the gig parameters for "release velocity response" curves
1468 - fine tuning of the EGADSR envelope
1469 - volume of release triggered samples now depends on note-on velocity,
1470 note length and gig parameter "release trigger decay" instead of
1471 note-off velocity.
1472 - revised voice stealing
1473 (fixes crash and endless loop caused by voice stealing)
1474 - don't reset scale tuning on instrument or audio output device change
1475 - handle key group conflicts right at the beginning of each fragment
1476 instead of when the respective voice is actually launched
1477 (fixes undefined behavior if stolen voices belonged to a key group -
1478 this case was followed by a "killed voice survived" error message)
1479 - fixed minor issue with null/silence samples
1480 (those stole voices even though they don't need a voice at all which
1481 resulted in "voice stealing didn't work out" messages)
1482 - don't reset volume, pan, pitch and MIDI controller values on
1483 instrument or audio output device change
1484
1485 * LSCP server:
1486 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1487 - fixed LSCP event "CHANNEL_INFO" notification
1488 (e.g. did not notify on volume changes or MIDI program change events)
1489
1490 * linuxsampler application:
1491 - added command line parameters --lscp-addr and --lscp-port to override
1492 default IP address and port of LSCP server
1493
1494 Version 0.3.1 (24 May 2005)
1495
1496 * initial release
