NKSP: Introducing floating point support.

* NKSP language: Added support for NKSP real number literals and
  arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").

* NKSP language: Added support for NKSP real number (floating point)
  script variables (declare ~foo := 3.4).

* NKSP language: Added support for NKSP real number (floating point)
  array script variables (declare ?foo[3] := ( 1.1, 2.7, 49.0 )).

* NKSP built-in script function "message()" accepts now real number
  argument as well.

* Added built-in NKSP script function "real_to_int()" and its short
  hand form "int()" for casting from real number to integer in NKSP
  scripts.

* Added built-in NKSP script function "int_to_real()" and its short
  hand form "real()" for casting from integer to real number in NKSP
  scripts.

* Bumped version (2.1.1.svn6).

1 schoenebeck 3548 Version SVN trunk (?)
2    
3     * general changes:
4     - Fixed compiler error in Pool.h.
5 schoenebeck 3557 - 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 schoenebeck 3550
11 schoenebeck 3551 * 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 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
18 schoenebeck 3561 - 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 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
37     and their potential metric prefix token.
38 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
39     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
40     - NKSP language: Added support for NKSP real number (floating point) script
41     variables (declare ~foo).
42     - NKSP language: Added support for NKSP real number (floating point) array
43     script variables (declare ?foo[]).
44     - Built-in script function "message()" accepts now real number argument as
45     well.
46     - Added built-in script function "real_to_int()" and its short hand form
47     "int()" for casting from real number to integer in NKSP scripts.
48     - Added built-in script function "int_to_real()" and its short hand form
49     "real()" for casting from integer to real number in NKSP scripts.
50 schoenebeck 3551
51 schoenebeck 3550 * test cases:
52 schoenebeck 3548 - Fixed compiler errors in test cases.
53     - Updated README for how to compile & run test cases.
54     - Updated test case
55     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
56     expected behaviour of the Mutex class implementation (recursive
57     mutex type).
58 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
59     functions.
60 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
61 schoenebeck 3548
62 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
63 schoenebeck 3381
64     * Real-time instrument scripts:
65     - Fixed behavior of built-in NKSP functions change_sustain(),
66     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
67     and change_cutoff_release().
68    
69 schoenebeck 3444 * general changes:
70     - Only play release trigger samples on sustain pedal up if this behaviour
71     was explicitly requested by the instrument (otherwise only on note-off).
72 persson 3455 - Fixed compiler warnings.
73     - Fixed compilation error when cross-compiling to Mac.
74 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
75     (see bug #169).
76     - LSCP doc: Be more clear describing the two distinct approaches
77     of using external vs. internal effects (see bug #169).
78 schoenebeck 3514 - "optional" class: Fixed comparison operators.
79 schoenebeck 3444
80 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
81     - Format extension: If requested by instrument then don't play release
82     trigger sample on note-off events.
83    
84 schoenebeck 3487 * SFZ format engine:
85     - Fixed memory leak when releasing samples
86     (fixes bug #307, patch by Jacek Roszkowski)
87 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
88     (fixes bug #308, patch by Jacek Roszkowski).
89 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
90     (fixes bug #310, patch by Jacek Roszkowski).
91 schoenebeck 3487
92 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
93 persson 2837
94 persson 2856 * SFZ format engine:
95     - added support for <global>, <master> and #define (patch by Alby M)
96 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
97     - Added support for sfz extension opcode 'script' which may be used to
98     load real-time instrument script file (NKSP script language).
99 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
100 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
101 persson 3291 - sfz parser: allow missing space between header and opcode
102 persson 2856
103 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
104 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
105     cutoff settings.
106 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
107     all if an up-pitch of more than 40 semi tones was requested (I don't
108     think there is any stock gig sound that requires this behavior to
109     resemble its original sound).
110 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
111     be aborted (as LinuxSampler extension to the original GigaStudio 4
112     format).
113 schoenebeck 3072
114 persson 2837 * general changes:
115     - fixed printf type errors (mostly in debug messages)
116 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
117 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
118     allowing to sort data efficiently in real-time safe manner.
119     - RTList class: added methods for moving/inserting elements to arbitrary
120     position within a list.
121     - RTList class: added method fromPtr() for creating an Iterator object from
122     a raw element pointer.
123     - Attempt to partly fix resetting engine channels vs. resetting engine, an
124     overall cleanup of the Reset*(), ConnectAudioDevice(),
125     DisconnectAudioDevice() API methods would still be desirable though,
126     because the current situation is still inconsistent and error prone.
127 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
128     being directly assigned to a keyboard key. This allows more fine graded
129     processing of voices, which is i.e. required for certain instrument
130     script features.
131 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
132     (CC #64) events.
133     - Fix: Release trigger voices can now also distinguish correctly between
134     note-off and sustain pedal up events.
135 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
136     (while slow rate of crossfade smoother is preserved) to allow quick
137     volume and pan changes by instrument scripts for instance.
138 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
139     properly and thus were ignored for certain uses.
140 schoenebeck 3018 - Added new C++ API method
141     VirtualMidiDevice::SendChannelPressureToSampler().
142 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
143     sub threads is 16-byte aligned
144 schoenebeck 3054 - fixed numerous compiler warnings
145 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
146 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
147     fixes potential undefined behavior.
148 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
149     have a valid sample mapped (fixes bug #252).
150     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
151 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
152     subsequent optional argument due to glibc's implementation oddity
153     which expects a "=" sign, but no space between them.
154 persson 2837
155 schoenebeck 2866 * packaging changes:
156     - removed unnecessary dependency to libuuid
157     (originated by libgig's usage of it)
158 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
159     auto detect whether it (sh/c)ould output its messages in color.
160 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
161     substitution variable.
162     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
163 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
164     linuxsampler with instruments DB support.
165 schoenebeck 2866
166 schoenebeck 2871 * Real-time instrument scripts:
167     - Implemented scheduler for delayed MIDI events and for suspended scripts.
168     - Built-in script function "wait()": implemented support for function's
169     "duration-us" argument, thus scripts using this function are now
170     correctly resumed after the requested amount of microseconds.
171     - Built-in script function "play_note()": implemented support for
172     function's "duration-us" argument, thus notes triggered with this
173     argument are now correctly released after the requested amount of
174     microseconds.
175     - Fix: script events were not cleared when engine channel was reset,
176     potentially causing undefined behavior.
177     - Fixed crash which happened when trying to reference an undeclared
178     variable.
179 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
180     special value -1 for "duration-us" argument, which will cause the
181     triggered note to be released once the original note was released.
182 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
183     - Added new API method ScriptVM::syntaxHighlighting() which provides
184     a convenient syntax highlighting backend for external instrument
185     script editor applications.
186 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
187     - Extended parser issues to provide not only first line and first
188     column, but also last line and last column of issue (thus marking
189     the precise span of the issue within the source code).
190 schoenebeck 2902 - Reload script automatically after being modified by an instrument
191     editor.
192 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
193     like "on note end on".

198     - Implemented built-in script function "change_reso()".
199     - Implemented built-in script function "event_status()".
200     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
201     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
202     "event_status()" function.
203     - NKSP language: Added support for bitwise operators ".or.", ".and."
204     and ".not.".
205     - NKSP language scanner: Fixed IDs matching to require at least one
206     character (i.e. when matching function names or variable names).
207     - NKSP language scanner: disabled unusued rules.
208 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
209     be distinguished engine internally from "real" MIDI note on/off
210     events in order to avoid misbehaviors like hanging notes.
211 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
212     - Implemented built-in script variable "$NKSP_REAL_TIMER".
213     - Implemented built-in script variable "$NKSP_PERF_TIMER".
214     - Implemented built-in script variable "$ENGINE_UPTIME".
215 schoenebeck 2945 - Implemented built-in script function "inc()".
216     - Implemented built-in script function "dec()".
217     - NKSP language fix: division expressions were evaluated too often.
218     - NKSP language fix: string concatenation operator was right
219     associative instead of left (to right).
220 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
221     (i.e. "if end if").
222 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
223     - Implemented built-in script variable "$NI_CALLBACK_ID".
224     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
225     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
226     - Added support for read-only built-in variables (respectively
227     handled by the script parser).

229     - Added built-in script constant "$NI_CB_TYPE_NOTE".
230     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

234     - Implemented built-in script function "change_decay()".
235     - Implemented built-in script function "change_release()".
236 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
237     synthesis parameter changes immediately in case the respective note
238     was triggered at the same time, instead of scheduling the parameter
239     change, especially because it would cause some parameter types's
240     changes either to be ramped (i.e. change_vol()) or other types even
241     to have not effect at all (i.e. change_attack()).
242 schoenebeck 2965 - Implemented built-in script function "sh_left()".
243     - Implemented built-in script function "sh_right()".
244 schoenebeck 2970 - Implemented built-in script function "min()".
245     - Implemented built-in script function "max()".
246 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
247     was loaded.
248     - NKSP built-in wait() script function: abort script execution if
249     a negative or zero wait time was passed as argument (since this is
250     a common indication of a bug either of the script or even of the
251     engine, which could lead to RT instability or even worse).
252 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
253     threatening scripts.
254 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
255 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
256     initializer list to an array variable.
257 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
258 schoenebeck 3076 - Implemented built-in script function "in_range()".

264     - Implemented built-in script function "change_tune_time()".
265     - Implemented built-in script function "fade_in()".
266     - Implemented built-in script function "fade_out()".
267     - Fixed acceptance of wrong data type of parameters passed to built-in
268     script functions "change_vol()", "change_tune()", "change_pan()",
269     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
270     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
271     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
272 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
273     of its possible parameter selections.
274     - Added built-in script function "set_event_par()" and implemented some
275     of its possible parameter selections.
276 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
277 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
278 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
279     built-in function "ignore_controller()".
280 schoenebeck 3214 - Implemented built-in script function "change_velo()".
281     - Implemented built-in script function "change_note()".
282 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
283     intuitive behavior if used in combination with "change_vol_time()" or
284     "change_tune_time()" respectively: now tuning/volume changes are only
285     assigned (without delay) immediately to a new note if the respective
286     timing function has not been called before, otherwise the volume/tuning
287     changes are automatically faded (before, only the event's time stamp was
288     relevant).
289 schoenebeck 3221 - Implemented built-in script function "array_equal()".
290     - Implemented built-in script function "search()".
291     - Implemented built-in script function "sort()".
292     - NKSP Fix: Never suspend "init" event handlers.
293 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
294     available for gig format engine).
295 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
296     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
297     - Implemented built-in script function "change_vol_curve()".
298     - Implemented built-in script function "change_tune_curve()".
299 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
300     offset with argument 3, where special value -1 means to use the regular
301     sample offset as defined by the instrument file.
302 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
303     - Built-in variable $EVENT_NOTE is now a read-only variable.
304     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
305     - built-in "play_note()" function now accepts -2 for its fourth argument
306     (note duration) which means the life time of the note shall be sticked
307     to the requested note number of argument 1.
308     - Fix: built-in "play_note()" function now returns 0 as result value if
309     -1 was passed for its fourth argument (note duration) and the respective
310     parent note is already gone.
311 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
312 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
313     - NKSP language: Raise parser warning if array variable is accessed with
314     an index that exceeds the array's size.
315 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
316 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
317     code blocks.

319     another script handler by passing its callback ID.
320 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
321     "init" event handlers.
322 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
323     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
324     to retrieve all code blocks filtered out by the preprocessor.
325 schoenebeck 3293 - Added built-in script function "fork()".
326     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
327     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
328     - Fixed potential crash when accessing dynamic built-in array variables.
329 schoenebeck 3296 - Added built-in script function "callback_status()".
330     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
331     - Added built-in constant $CALLBACK_STATUS_QUEUE.
332     - Added built-in constant $CALLBACK_STATUS_RUNNING.
333 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",

335     for doubling the respective time.
336 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
337     to a lexer start condition stack underrun.
338     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
339     USE_CODE_IF_NOT() preprocessor statements.
340 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
341     can be set to disable all subsequent built-in "message()" function calls
342     on preprocessor level.
343 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
344 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
345     to avoid the editor app to crash on ill-formed text input.
346 schoenebeck 3335 - Added built-in script function "change_pan_time()".
347     - Added built-in script function "change_pan_curve()".

404 persson 2382
405 persson 2086 * general changes:
406 iliev 2012 - Refactoring: moved the independent code from
407     the Gigasampler format engine to base classes
408 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
409     respective profiling code is currently broken
410 schoenebeck 2053 - Introduced support for optional environment variable
411     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
412     where the sampler shall look for instrument editor plugins
413     (patch by Luis Garrido, slightly modified).
414 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
415     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
416     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
417     note (in this implementation of the sampler its simply hard routed to
418     the 1st effect send of the sampler channel, no matter what the actual
419     effect type is)
420     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
421     note (in this implementation of the sampler its simply hard routed to
422     the 2nd effect send of the sampler channel, no matter what the actual
423     effect type is)
424 schoenebeck 2124 - implemented support for internal LADSPA effects
425 schoenebeck 2140 - raised limit of program change queue from 100 to 512
426     (as suggested by Alex Stone)
427 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
428 iliev 2296 - experimental support for per voice equalization
429 iliev 2306 - added command line option --exec-after-init
430 schoenebeck 2330 - Introduced new C++ API method:
431     EngineChannel::InstrumentFileName(int index)
432     allowing to retrieve the whole list of files used for the loaded
433     instrument on an engine channel (a.k.a. part). Some GigaStudio
434     instruments for example are splitted over several files like
435     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
436 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
437     - Added new C++ API method Sampler::GetGlobalMaxStreams().
438     - Added new C++ API method Sampler::SetGlobalMaxVoices().
439     - Added new C++ API method Sampler::SetGlobalMaxStreams().
440 schoenebeck 2377 - Various "const" and "restrict" optimizations.
441 persson 2382 - all engines: add pan CC value to instrument pan parameter before
442     applying panning, instead of using two separate pan functions in
443     series (#182)
444 persson 2427 - added a lock guard class for exception safe mutex handling and
445     used it everywhere appropriate
446 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
447     - Exposed scale tuning to C++ API (along to the already existing standard
448     SysEx way).
449 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
450     and broken for ppc64. (Seq_cst loads and stores are actually not
451     used in LS, so the bug wasn't noticable.)
452     - lsatomic.h: added ARMv7 support
453 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
454     added various new C++ methods for this new feature / design change, old
455     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
456     as deprecated but are still there and should provide full behavior
457     backward compatibility).
458     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
459     unsafe and caused compilation error with clang 2.x).
460 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
461 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
462     sampler from the command line by providing LSCP aware features.
463 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
464     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
465     - VirtualMidiDevice: Added support for pitch bend.
466 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
467     polyphonic key pressure events (so far polyphonic pressure was not
468     supported at all, and channel pressure was rerouted as CC128 but not
469     used so far).
470 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
471     code is shared by all sampler engine implemementations, however only the
472     gig file format currently provides support for storing instrument scripts
473     (as LinuxSampler extension to the original GigaStudio 4 format).
474 iliev 2012
475 persson 2043 * Gigasampler format engine:
476     - implemented the "round robin keyboard" dimension
477     - fixed round robin and random dimensions for cases when number of
478     dimension zones is not a power of two

480     key
481 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
482     - bugfix: filter keyboard tracking was broken

484     filter parameters in each sub fragment)
485     - handle special case when pan parameter in gig file has max or
486     min value
487 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
488     doesn't sound naturally with a drumkit
489 persson 2408 - fixed EG1 modulation when attack or release is zero
490 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.

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

959     a pointer to the launched InstrumentEditor object
960 schoenebeck 1876 - added optional 3rd party user data parameter for following

1046     connected to the respective MIDI input port the SysEx message arrived
1047     on)
1048 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1049     sometimes wrongly killed in the same buffer, causing no sound to
1050     be played
1051 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1052     which is usally used to switch a part between chromatic sounds and
1053     drumkit sounds (as opposed to their common default setting of MIDI
1054     part 10 being a drumkit part and all other ones chromatic parts), in
1055     LS however one can switch between the first 16 MIDI instrument maps
1056     defined for the sampler
1057 persson 1764 - made it possible to create multiple sample channels even if the
1058     audio thread isn't running
1059 persson 1844 - fixed crash when removing channel with active voices (#116)
1060 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1061     un-cache the respective sample if it's really not used by any
1062     sampler engine anymore
1063     - re-cache samples in case they were changed by an instrument editor,
1064     e.g. when a sample was added while playing (#82)
1065 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1066     same time stamp as the voice's note-on event and occured both in the
1067     same audio fragment cycle (fixes bug #112)
1068 persson 1858 - added support for the "fine tune" and "pitch bend range"
1069     instrument-level gig parameters
1070     - fixed minor artifacts in pitch bend handling
1071 schoenebeck 1860 - added support for GS Reset SysEx message
1072 persson 1862 - allow gig files to use unlimited downward pitch shifting
1073     - added a limit check for upward pitch shifting
1074 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1075     note was silent
1076 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1077     same time a new instrument was loading
1078 persson 1644
1079 schoenebeck 1687 * LSCP server:
1080     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1081     react on MIDI data arriving on certain sampler channels (so far only
1082     Note-On and Note-Off events are sent via this LSCP event)
1083 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1084     react on MIDI data arriving on certain MIDI input devices (so far only
1085     Note-On and Note-Off events are sent via this LSCP event)
1086 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1087     SET DB_INSTRUMENT FILE_PATH
1088 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1089     frontends to send MIDI messages to specific sampler channel
1090     - added two additional fields to GET FILE INSTRUMENT INFO command -
1091     KEY_BINDINGS and KEYSWITCH_BINDINGS
1092 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1093     was incorrect
1094 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1095 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1096     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1097     be triggered respectively
1098     - added new LSCP command "SET STREAMS" to globally alter the maximum
1099     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1100     which will be triggered respectively
1101 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1102     a gigedit file dialog is opened)
1103 iliev 1848 - close all connections when LSCPServer is deleted
1104 iliev 1882 - hard close of all sockets on exit
1105 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1106     driver
1107 schoenebeck 1687
1108 iliev 1761 * Bug fixes:
1109     - fixed a crash which occurs when removing a sampler channel waiting
1110     to start instrument loading after another channel
1111 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1112     instrument loading in progress (bug #113)
1113 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1114     instrument with PERSISTENT load mode
1115 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1116     - fixed memory leaks when issuing the following LSCP commands:
1117     GET AUDIO_OUTPUT_DRIVER INFO
1118     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1119     GET MIDI_INPUT_DRIVER INFO
1120     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1121     - fixed possible compilation error when sqlite is not present
1122 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1123 iliev 1847 - fixed crash when changing the audio output device of a sampler
1124     channel with loaded instrument and start playing notes
1125 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1126 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1127     PowerPC, which probably could cause crashes on that platform
1128 persson 1889 - fixed a memory management error which could cause a crash when a
1129     plugin was unloaded
1130 persson 1896 - bugfix: two private structs had the same name, which could cause
1131     problems if the linker chose the wrong constructor
1132 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1133     Windows

1136 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1137 schoenebeck 1454
1138     * packaging changes:
1139     - added autoconf checks for pthread library
1140     - added autoconf check for pthread bug found on certain NPTL-enabled
1141     glibc versions (see Gentoo bug report #194076)
1142 senoner 1502 - added autoconf checks for MS Windows
1143 schoenebeck 1454
1144 persson 1455 * general changes:
1145     - bugfix: the thread used by an editor plugin didn't die when the
1146     editor closed
1147 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1148     out all the space. operator--() did not apply size_mask after
1149     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1150     order to avoid problems with the _NonVolatileReader functions.
1151     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1152     GetWriteSpace(). Since this function is currently only used in
1153     the stream's qsort() compare function, it didn't trigger any
1154     bugs.
1155     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1156     24bit mode too. Faster method to read 24bit words on little
1157     endian machines (x86): replaced 3 byte reads + shifts with a 1
1158     unaligned 32bit read and shift
1159     - experimental support for MS Windows (MIDI input via MME, AUDIO
1160     output via ASIO)
1161     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1162 iliev 1541 - support for monitoring the total number of active disk streams
1163     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1164     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1165 persson 1455
1166 senoner 1500 * AUDIO driver:
1167 persson 1534 - added Windows ASIO low latency audio driver
1168 senoner 1500
1169 senoner 1485 * MIDI driver:
1170 schoenebeck 1495 - added MME Windows MIDI driver
1171 senoner 1485
1172 schoenebeck 1471 * LSCP server:
1173     - added support for Windows style path / filenames, however with
1174     forward slash path separators instead of backslash
1175     (i.e. "C:/foo/bar.gig")
1176 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1177     apostrophes as well
1178 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1179     "LIST FILE INSTRUMENTS <file>" and
1180     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1181     about an arbitrary instrument file on the system where the sampler is
1182     running on
1183 schoenebeck 1471
1184 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1185 schoenebeck 947
1186 schoenebeck 1065 * packaging changes:
1187 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1188     API header files anymore
1189 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1190     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1191 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1192     capable to execute our autoconf environment, thus no need anymore
1193     to maintain the compile time configuration file (osx/version.h) for
1194     OSX manually (patch by Toshi Nagata)
1195 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1196     parameters
1197 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1198     C++ API header files, all implementation internal global definitions
1199     are now in global_private.h
1200     - atomic.h is not exposed to the C++ API anymore
1201     - no need to include config.h anymore for using LS's API header files
1202     - fixed warnings in API doc generation
1203 schoenebeck 1065
1204 schoenebeck 947 * general changes:
1205     - replaced the old, confusing MIDI program change mechanism by a
1206     flexible MIDI instrument mapper which allows to map arbitrary
1207 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1208 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1209     loaded on the respective channel when such MIDI program change
1210     messages arrive, beside that, each entry allows to define a life-time
1211     strategy for the instrument, so the user can define whether the
1212     instrument should i.e. be permanently loaded (to be able to switch
1213     quickly among sounds) or i.e. loaded just on demand when the
1214     respective program change arrives (to safe RAM space), as well as a
1215     global volume factor for each entry, so the user can adjust the volume
1216     dynamic of his mapped instrument collection without having to modify
1217 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1218     MIDI instrument maps and assign each sampler channel individually
1219     a certain map, so that i.e. separation of normal instruments and
1220     drumkits is possible
1221 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1222     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1223 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1224     due to a constant size RingBuffer FIFO which is now replaced by a
1225     dynamic (unlimited) size std::list FIFO
1226 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1227     output channels for being processed by external effect processors
1228     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1229     controllers
1230 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1231 iliev 1130 - Implemented new, improved notification system
1232 schoenebeck 1149 - fixed compilation errors regarding OSX
1233     (patch by Toshi Nagata)
1234 iliev 1161 - implemented instruments database
1235 iliev 1345 - added support for escape sequences to the instruments database
1236 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1237     within the sampler's process (by using instrument editor plugins),
1238     you'll notice the new "Registered instrument editors:" message on
1239 schoenebeck 1407 startup, added a new LSCP command:
1240     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1241 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1242     given sampler channel, the plugin path can be overridden at compile
1243     time with ./configure --enable-plugin-dir=/some/dir
1244 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1245     in the sampler's process to safely edit instruments while playing
1246     without a crash (hopefully) by either suspending single regions
1247     wherever possible or if unavoidable whole engine(s)
1248 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1249     policy and priority on thread level, set a minimum stack size for
1250     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1251     threads simply inherited properties of starting thread instead of
1252     setting their own policy and priority
1253 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1254     main process did not wait for the stack trace process to finish
1255     its output
1256 persson 1248 - fixed some minor memory leaks
1257 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1258     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1259 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1260     register, to avoid relocations in the text segment at runtime)
1261 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1262 schoenebeck 947
1263     * MIDI driver:
1264     - dispatch bank select (MSB and LSB) messages
1265    
1266 schoenebeck 1049 * audio driver:
1267     - the ALSA audio output driver parameters now reflect the correct
1268     parameter value ranges for the respective selected sound card
1269     (patch by Till Wimmer, a bit fixed and extended)
1270    
1271 persson 951 * Gigasampler format engine:
1272     - if a filter is used and EG2 finishes before EG1, let the voice
1273     die when EG2 has finished (this fixes a problem with clicks and
1274     voice starvation for some gigs)
1275 persson 1038 - playback is no longer disabled during instrument loading
1276     - all notes playing on a channel that changes its instrument keep
1277     playing with the old instrument until they get a note off
1278     command
1279 persson 1039 - EG fix: a release value of zero could cause noises or crash
1280 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1281 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1282     above max sustain level, which means that there is a decay phase
1283     even if sustain is 100%
1284 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1285     noises or crashes
1286 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1287 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1288     supplied to the configure script (fixes #46)
1289 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1290     instead of a fix value
1291 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1292     127 (solo mode) only kill voices if the respective mode really
1293     changed
1294 persson 951
1295 schoenebeck 1244 * LSCP server:
1296     - fixed compile time error for old Bison versions
1297     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1298 schoenebeck 1245 - parser now supports extended ASCII character set
1299     (up to ASCII code 255, i.e. includes now umlauts and accents)
1300     - filename arguments in LSCP commands now allow to use escape
1301     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1302     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1303     code value like \xf2) (fixes bug #24)
1304 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1305     least one of their text-based parameters (i.e. name, description):
1306     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1307     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1308     "SET DB_INSTRUMENT_DIRECTORY NAME",
1309     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1310     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1311     "FIND DB_INSTRUMENT_DIRECTORIES"
1312 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1313     occured, the unexpected character and the actually expected, possible
1314     character(s), the latter only if less than 5 possibilities)
1315 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1316     settings
1317 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1318     of strings were treated as being one string containing commas
1319     (fixes #57)
1320 schoenebeck 1244
1321 iliev 959 * Bug fixes:
1322     - fixed crash occurring on certain LSCP scripts (Bug 39)
1323 persson 1038 - another thread safety fix for lscp "load engine" and "set
1324     channel audio output device"
1325 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1326     on a sampler channel with connected MIDI device
1327 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1328     device connected to a sampler channel to number less then or equal
1329     to the index of the port to which the sampler channel is connected.
1330 iliev 1296 - The previous bindings were not been disconnected when altering
1331     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1332     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1333 iliev 1297 - The active stream/voice count statistic was incorrect.
1334 iliev 1298 - notification events were not been sent for some sampler
1335     channel changes
1336 iliev 1305 - added default min and max values to restrict the number of allowed
1337     audio output channels and MIDI input ports
1338 iliev 1306 - the connection to the PCM interface is now closed when destroying
1339     an audio output device
1340 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1341 iliev 959
1342 schoenebeck 1221 * test cases:
1343     - updated and fixed (haven't been touched in a while)
1344    
1345 schoenebeck 937 Version 0.4.0 (24 November 2006)
1346 persson 696
1347 schoenebeck 697 * packaging changes:
1348 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1349     to post-(un)install steps; added devel package for liblinuxsampler;
1350     to linuxsampler.spec (RPM)
1351 schoenebeck 697 - install necessary development header files for allowing 3rd party
1352     applications to link against liblinuxsampler
1353     - liblinuxsampler's API documentation can be generated with 'make docs'
1354     (Doxygen required)
1355 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1356     implementation (currently either an integer math solution or a
1357     di-harmonic approximation), automatic detection can be overriden
1358     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1359     configure script argument though (mandatory for cross-compilation)
1360 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1361     provided some on his own (as CXXFLAGS)
1362 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1363     messages
1364 schoenebeck 852 - added compile time options to allow disabling the various audio and
1365     MIDI drivers
1366 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1367     (patch by Ebrahim Mayat)
1368 schoenebeck 697
1369 persson 696 * Gigasampler format engine:
1370 schoenebeck 738 - extensive synthesis optimization
1371     (reimplementation of EGs and LFO(s), removed synthesis parameter
1372     prerendering and the synthesis parameter matrix in general, splitting
1373     each audio fragment into subfragments now where each subfragment uses
1374 persson 830 constant pitch and filter coefficients. The volume coefficient is
1375     linearly interpolated inside a subfragment, unless
1376     --disable-interpolate-volume is set.)
1377 persson 696 - fine tuning of the EG modulation parameters
1378 persson 729 - improved filter cutoff calculation by adding support for the
1379     following gig parameters: Cutoff freq (used when no cutoff
1380     controller is defined), Control invert, Minimum cutoff, Velocity
1381 persson 791 curve and Velocity range. The keyboard tracking now scales
1382     cutoff frequency instead of resonance.
1383 persson 877 - added support for gig parameter Resonance.
1384 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1385 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1386     which can be overridden with --enable-global-attenuation
1387 persson 783 - EG fixes: made the length of "attack hold" stage more
1388     accurate. Release stage can now start before attack stage
1389 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1390     time now has a minimal value to prevent clicks.
1391 persson 799 - fixed pitch changes larger than one octave
1392 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1393     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1394     all modes can be altered via standard GM messages, that is CC5 for
1395     altering portamento time, CC65 for enabling / disabling portamento
1396     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1397 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1398     parameter) and crossfade
1399 persson 831 - added support for the "attenuation controller threshold" gig
1400     parameter
1401 persson 832 - added smoothing of volume changes caused by control change
1402     messages
1403 persson 865 - sample loop parameters are now taken from the DimensionRegion
1404     instead of the wave chunk
1405     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1406     not equal to a power of two
1407 persson 877 - reimplementation of the filter algorithm. The new filter is more
1408     accurate and supports all gig filter types, including bandreject
1409     and lowpass turbo.
1410 persson 903 - real support for 24 bit samples - samples are not truncated to
1411     16 bits anymore
1412     - support for aftertouch (channel pressure, not polyphonic
1413     aftertouch)
1414 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1415     amplifying from 0)
1416 persson 696
1417 schoenebeck 711 * LSCP server:
1418     - fixed application exit on broken pipe error (fixes bug #20)
1419 iliev 793 - fixed the notification messages delay due to lack of
1420     network activity (fixes bug #26)
1421 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1422     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1423 schoenebeck 711
1424 schoenebeck 838 * audio driver:
1425     - added aRts audio output driver (by no means RT safe)
1426    
1427 schoenebeck 775 * MIDI driver:
1428     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1429     messages several times instead of once
1430 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1431     for events (i.e. for offline rendering based MIDI drivers)
1432 persson 922 - added checks for bad MIDI data
1433 schoenebeck 775
1434 schoenebeck 900 * linuxsampler application:
1435     - show available sampler engine types on startup
1436    
1437 schoenebeck 705 * general changes:
1438     - support for muting sampler channels and solo mode of the same, two new
1439     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1440     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1441     introduced for this, the behavior is the same like on a mixer console
1442 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1443     --enable-process-muted-channels which can be used to enable the
1444     processing of muted channels.
1445 iliev 777 - support for sostenuto pedal
1446 iliev 779 - support for monitoring the total number of active voices
1447 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1448     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1449 persson 835 - fixed some memory management errors
1450 persson 841 - fixed some concurrency problems that could lead to crashes when
1451     LSCP commands were executed
1452 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1453     sampler channel (fixes bug #36)
1454 schoenebeck 705
1455 schoenebeck 692 Version 0.3.3 (15 July 2005)
1456 schoenebeck 686
1457     * packaging changes:
1458     - fixed compilation with gcc 4.0
1459    
1460 schoenebeck 687 * Gigasampler format engine:
1461     - LFO preprocessing was performed even though the respective LFO was
1462     disabled by the instrument patch (minor efficiency fix)
1463 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1464     for volume ramp downs in the same fragment (needed for current voice
1465     stealing implementation) then simply inform the user with a warning
1466     about possible click sounds and reduce the volume ramp down
1467     appropriately instead of cancelling the audio device connection
1468 schoenebeck 687
1469 schoenebeck 677 Version 0.3.2 (24 June 2005)
1470 schoenebeck 609
1471     * packaging changes:
1472     - updated autotools build files to compile on OS X
1473     (conditional compilation of CoreMIDI and MidiShare drivers)
1474 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1475     './configure --disable-asm' (definitely not recommended)
1476 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1477     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1478     (due to 'dist-bzip2' automake option)
1479 schoenebeck 649
1480     * Gigasampler format engine:
1481     - support for the gig parameters for "release velocity response" curves
1482     - fine tuning of the EGADSR envelope
1483     - volume of release triggered samples now depends on note-on velocity,
1484     note length and gig parameter "release trigger decay" instead of
1485     note-off velocity.
1486 schoenebeck 663 - revised voice stealing
1487     (fixes crash and endless loop caused by voice stealing)
1488 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1489 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1490     instead of when the respective voice is actually launched
1491     (fixes undefined behavior if stolen voices belonged to a key group -
1492     this case was followed by a "killed voice survived" error message)
1493 schoenebeck 669 - fixed minor issue with null/silence samples
1494     (those stole voices even though they don't need a voice at all which
1495     resulted in "voice stealing didn't work out" messages)
1496 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1497     instrument or audio output device change
1498 schoenebeck 654
1499 schoenebeck 620 * LSCP server:
1500 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1501 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1502 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1503 schoenebeck 609
1504 schoenebeck 668 * linuxsampler application:
1505     - added command line parameters --lscp-addr and --lscp-port to override
1506     default IP address and port of LSCP server
1507    
1508 schoenebeck 579 Version 0.3.1 (24 May 2005)
1509    
1510     * initial release
