NKSP: Added some initial floating point test cases.

* RTMath: Implemented floating point comparison methods
  fEqual32(float,float) and fEqual64(double,double)
  which take the expected floating point tolerances
  into account.

* NKSP: Allow built-in exit() function to potentially
  accept real type argument as well.

* NKSP: Added real number test cases for built-in
  functions exit(), int_to_real(), real(), real_to_int()
  and int(), as well as for the plus, minus and negate
  language operators.

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 3575 - RTMath: Implemented floating point comparison methods
11     fEqual32(float,float) and fEqual64(double,double) which take the
12     expected floating point tolerances into account.
13 schoenebeck 3550
14 schoenebeck 3551 * Real-time instrument scripts:
15     - Added method ScriptVM::setExitResultEnabled() which allows to
16     explicitly enable the built-in exit() function to optionally accept
17     one function argument; the value of the passed exit() function
18     argument will then become available by calling
19     VMExecContext::exitResult() after script execution.
20 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
21 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
22     with a regular character (a-z or A-Z); starting them with a digit or
23     underscore is not allowed.
24     - NKSP parser fix: equal comparison operator "=" and not equal comparison
25     operator "#" must only accept integer operands.
26     - NKSP language: Implemented support for standard units like Hertz, seconds,
27     Bel including support for metric unit prefixes; so one can now e.g.
28     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
29     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
30     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
31     - NKSP language: Introduced "final" operator "!" which is specifically
32     intended for synthesis parameter values to denote that the synthesis
33     parameter value is intended to be the "final" value for that synthesis
34     parameter that should explicitly be used by the engine and thus causing
35     the sampler engine to ignore all other modulation sources for the same
36     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
37     variable or formula with this new "!" operator the expression is marked as
38     being "final".
39 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
40     and their potential metric prefix token.
41 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
42     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
43     - NKSP language: Added support for NKSP real number (floating point) script
44     variables (declare ~foo).
45     - NKSP language: Added support for NKSP real number (floating point) array
46     script variables (declare ?foo[]).
47     - Built-in script function "message()" accepts now real number argument as
48     well.
49     - Added built-in script function "real_to_int()" and its short hand form
50     "int()" for casting from real number to integer in NKSP scripts.
51     - Added built-in script function "int_to_real()" and its short hand form
52     "real()" for casting from integer to real number in NKSP scripts.
53 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
54     argument as well.
55 schoenebeck 3551
56 schoenebeck 3550 * test cases:
57 schoenebeck 3548 - Fixed compiler errors in test cases.
58     - Updated README for how to compile & run test cases.
59     - Updated test case
60     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
61     expected behaviour of the Mutex class implementation (recursive
62     mutex type).
63 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
64     functions.
65 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
66 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
67     int_to_real(), real(), real_to_int() and int(), as well as for the
68     plus, minus and negate language operators.

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

206     - Implemented built-in script function "change_reso()".
207     - Implemented built-in script function "event_status()".
208     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
209     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
210     "event_status()" function.
211     - NKSP language: Added support for bitwise operators ".or.", ".and."
212     and ".not.".
213     - NKSP language scanner: Fixed IDs matching to require at least one
214     character (i.e. when matching function names or variable names).
215     - NKSP language scanner: disabled unusued rules.
216 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
217     be distinguished engine internally from "real" MIDI note on/off
218     events in order to avoid misbehaviors like hanging notes.
219 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
220     - Implemented built-in script variable "$NKSP_REAL_TIMER".
221     - Implemented built-in script variable "$NKSP_PERF_TIMER".
222     - Implemented built-in script variable "$ENGINE_UPTIME".
223 schoenebeck 2945 - Implemented built-in script function "inc()".
224     - Implemented built-in script function "dec()".
225     - NKSP language fix: division expressions were evaluated too often.
226     - NKSP language fix: string concatenation operator was right
227     associative instead of left (to right).
228 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
229     (i.e. "if end if").
230 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
231     - Implemented built-in script variable "$NI_CALLBACK_ID".
232     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
233     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
234     - Added support for read-only built-in variables (respectively
235     handled by the script parser).
236     - Added built-in script constant "$NI_CB_TYPE_INIT".
237     - Added built-in script constant "$NI_CB_TYPE_NOTE".
238     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
239     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
240 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
241 schoenebeck 2953 - Implemented built-in script function "change_attack()".
242     - Implemented built-in script function "change_decay()".
243     - Implemented built-in script function "change_release()".
244 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
245     synthesis parameter changes immediately in case the respective note
246     was triggered at the same time, instead of scheduling the parameter
247     change, especially because it would cause some parameter types's
248     changes either to be ramped (i.e. change_vol()) or other types even
249     to have not effect at all (i.e. change_attack()).
250 schoenebeck 2965 - Implemented built-in script function "sh_left()".
251     - Implemented built-in script function "sh_right()".
252 schoenebeck 2970 - Implemented built-in script function "min()".
253     - Implemented built-in script function "max()".
254 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
255     was loaded.
256     - NKSP built-in wait() script function: abort script execution if
257     a negative or zero wait time was passed as argument (since this is
258     a common indication of a bug either of the script or even of the
259     engine, which could lead to RT instability or even worse).
260 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
261     threatening scripts.
262 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
263 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
264     initializer list to an array variable.
265 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
266 schoenebeck 3076 - Implemented built-in script function "in_range()".

270     - Implemented built-in script function "change_pitch_lfo_freq()".
271 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
272     - Implemented built-in script function "change_tune_time()".
273     - Implemented built-in script function "fade_in()".
274     - Implemented built-in script function "fade_out()".
275     - Fixed acceptance of wrong data type of parameters passed to built-in
276     script functions "change_vol()", "change_tune()", "change_pan()",
277     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
278     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
279     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
280 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
281     of its possible parameter selections.
282     - Added built-in script function "set_event_par()" and implemented some
283     of its possible parameter selections.
284 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
285 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
286 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
287     built-in function "ignore_controller()".
288 schoenebeck 3214 - Implemented built-in script function "change_velo()".
289     - Implemented built-in script function "change_note()".
290 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
291     intuitive behavior if used in combination with "change_vol_time()" or
292     "change_tune_time()" respectively: now tuning/volume changes are only
293     assigned (without delay) immediately to a new note if the respective
294     timing function has not been called before, otherwise the volume/tuning
295     changes are automatically faded (before, only the event's time stamp was
296     relevant).
297 schoenebeck 3221 - Implemented built-in script function "array_equal()".
298     - Implemented built-in script function "search()".
299     - Implemented built-in script function "sort()".
300     - NKSP Fix: Never suspend "init" event handlers.
301 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
302     available for gig format engine).
303 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
304     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
305     - Implemented built-in script function "change_vol_curve()".
306     - Implemented built-in script function "change_tune_curve()".
307 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
308     offset with argument 3, where special value -1 means to use the regular
309     sample offset as defined by the instrument file.
310 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
311     - Built-in variable $EVENT_NOTE is now a read-only variable.
312     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
313     - built-in "play_note()" function now accepts -2 for its fourth argument
314     (note duration) which means the life time of the note shall be sticked
315     to the requested note number of argument 1.
316     - Fix: built-in "play_note()" function now returns 0 as result value if
317     -1 was passed for its fourth argument (note duration) and the respective
318     parent note is already gone.
319 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
320 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
321     - NKSP language: Raise parser warning if array variable is accessed with
322     an index that exceeds the array's size.

324 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
325     code blocks.
326 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
327     another script handler by passing its callback ID.
328 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
329     "init" event handlers.
330 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
331     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
332     to retrieve all code blocks filtered out by the preprocessor.
333 schoenebeck 3293 - Added built-in script function "fork()".
334     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
335     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
336     - Fixed potential crash when accessing dynamic built-in array variables.

338     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
339     - Added built-in constant $CALLBACK_STATUS_QUEUE.
340     - Added built-in constant $CALLBACK_STATUS_RUNNING.
341 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
342     "change_decay()" and "change_release()" to i.e. allow passing 2000000
343     for doubling the respective time.
344 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
345     to a lexer start condition stack underrun.
346     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
347     USE_CODE_IF_NOT() preprocessor statements.
348 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
349     can be set to disable all subsequent built-in "message()" function calls
350     on preprocessor level.
351 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
352 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
353     to avoid the editor app to crash on ill-formed text input.
354 schoenebeck 3335 - Added built-in script function "change_pan_time()".
355     - Added built-in script function "change_pan_curve()".

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

492     filter parameters in each sub fragment)
493     - handle special case when pan parameter in gig file has max or
494     min value
495 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
496     doesn't sound naturally with a drumkit

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

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

1035     the instruments DB file is located in
1036     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1037     databases for each windows user
1038     if no DB is present it automatically creates the .linuxsampler subdir
1039     and then creates an empty DB
1040 persson 1943 - fixed recursive import, which was broken on Windows
1041 iliev 1603

1054     connected to the respective MIDI input port the SysEx message arrived
1055     on)
1056 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1057     sometimes wrongly killed in the same buffer, causing no sound to
1058     be played
1059 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1060     which is usally used to switch a part between chromatic sounds and
1061     drumkit sounds (as opposed to their common default setting of MIDI
1062     part 10 being a drumkit part and all other ones chromatic parts), in
1063     LS however one can switch between the first 16 MIDI instrument maps
1064     defined for the sampler
1065 persson 1764 - made it possible to create multiple sample channels even if the
1066     audio thread isn't running
1067 persson 1844 - fixed crash when removing channel with active voices (#116)
1068 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1069     un-cache the respective sample if it's really not used by any
1070     sampler engine anymore
1071     - re-cache samples in case they were changed by an instrument editor,
1072     e.g. when a sample was added while playing (#82)
1073 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1074     same time stamp as the voice's note-on event and occured both in the
1075     same audio fragment cycle (fixes bug #112)
1076 persson 1858 - added support for the "fine tune" and "pitch bend range"
1077     instrument-level gig parameters
1078     - fixed minor artifacts in pitch bend handling
1079 schoenebeck 1860 - added support for GS Reset SysEx message
1080 persson 1862 - allow gig files to use unlimited downward pitch shifting
1081     - added a limit check for upward pitch shifting
1082 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1083     note was silent
1084 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1085     same time a new instrument was loading
1086 persson 1644
1087 schoenebeck 1687 * LSCP server:
1088     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1089     react on MIDI data arriving on certain sampler channels (so far only
1090     Note-On and Note-Off events are sent via this LSCP event)
1091 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1092     react on MIDI data arriving on certain MIDI input devices (so far only
1093     Note-On and Note-Off events are sent via this LSCP event)
1094 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1095     SET DB_INSTRUMENT FILE_PATH
1096 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1097     frontends to send MIDI messages to specific sampler channel
1098     - added two additional fields to GET FILE INSTRUMENT INFO command -
1099     KEY_BINDINGS and KEYSWITCH_BINDINGS
1100 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1101     was incorrect
1102 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1103 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1104     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1105     be triggered respectively
1106     - added new LSCP command "SET STREAMS" to globally alter the maximum
1107     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1108     which will be triggered respectively
1109 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1110     a gigedit file dialog is opened)
1111 iliev 1848 - close all connections when LSCPServer is deleted
1112 iliev 1882 - hard close of all sockets on exit
1113 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1114     driver
1115 schoenebeck 1687
1116 iliev 1761 * Bug fixes:
1117     - fixed a crash which occurs when removing a sampler channel waiting
1118     to start instrument loading after another channel
1119 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1120     instrument loading in progress (bug #113)
1121 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1122     instrument with PERSISTENT load mode
1123 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1124     - fixed memory leaks when issuing the following LSCP commands:
1125     GET AUDIO_OUTPUT_DRIVER INFO
1126     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1127     GET MIDI_INPUT_DRIVER INFO
1128     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1129     - fixed possible compilation error when sqlite is not present
1130 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1131 iliev 1847 - fixed crash when changing the audio output device of a sampler
1132     channel with loaded instrument and start playing notes
1133 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1134 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1135     PowerPC, which probably could cause crashes on that platform
1136 persson 1889 - fixed a memory management error which could cause a crash when a
1137     plugin was unloaded
1138 persson 1896 - bugfix: two private structs had the same name, which could cause
1139     problems if the linker chose the wrong constructor
1140 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1141     Windows
1142 iliev 1761
1143    
1144 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1145 schoenebeck 1454
1146     * packaging changes:
1147     - added autoconf checks for pthread library
1148     - added autoconf check for pthread bug found on certain NPTL-enabled
1149     glibc versions (see Gentoo bug report #194076)
1150 senoner 1502 - added autoconf checks for MS Windows
1151 schoenebeck 1454
1152 persson 1455 * general changes:
1153     - bugfix: the thread used by an editor plugin didn't die when the
1154     editor closed
1155 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1156     out all the space. operator--() did not apply size_mask after
1157     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1158     order to avoid problems with the _NonVolatileReader functions.
1159     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1160     GetWriteSpace(). Since this function is currently only used in
1161     the stream's qsort() compare function, it didn't trigger any
1162     bugs.
1163     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1164     24bit mode too. Faster method to read 24bit words on little
1165     endian machines (x86): replaced 3 byte reads + shifts with a 1
1166     unaligned 32bit read and shift
1167     - experimental support for MS Windows (MIDI input via MME, AUDIO
1168     output via ASIO)
1169     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1170 iliev 1541 - support for monitoring the total number of active disk streams
1171     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1172     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1173 persson 1455
1174 senoner 1500 * AUDIO driver:
1175 persson 1534 - added Windows ASIO low latency audio driver
1176 senoner 1500
1177 senoner 1485 * MIDI driver:
1178 schoenebeck 1495 - added MME Windows MIDI driver
1179 senoner 1485
1180 schoenebeck 1471 * LSCP server:
1181     - added support for Windows style path / filenames, however with
1182     forward slash path separators instead of backslash
1183     (i.e. "C:/foo/bar.gig")
1184 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1185     apostrophes as well
1186 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1187     "LIST FILE INSTRUMENTS <file>" and
1188     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1189     about an arbitrary instrument file on the system where the sampler is
1190     running on
1191 schoenebeck 1471
1192 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1193 schoenebeck 947
1194 schoenebeck 1065 * packaging changes:
1195 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1196     API header files anymore
1197 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1198     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1199 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1200     capable to execute our autoconf environment, thus no need anymore
1201     to maintain the compile time configuration file (osx/version.h) for
1202     OSX manually (patch by Toshi Nagata)
1203 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1204     parameters
1205 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1206     C++ API header files, all implementation internal global definitions
1207     are now in global_private.h
1208     - atomic.h is not exposed to the C++ API anymore
1209     - no need to include config.h anymore for using LS's API header files
1210     - fixed warnings in API doc generation
1211 schoenebeck 1065
1212 schoenebeck 947 * general changes:
1213     - replaced the old, confusing MIDI program change mechanism by a
1214     flexible MIDI instrument mapper which allows to map arbitrary
1215 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1216 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1217     loaded on the respective channel when such MIDI program change
1218     messages arrive, beside that, each entry allows to define a life-time
1219     strategy for the instrument, so the user can define whether the
1220     instrument should i.e. be permanently loaded (to be able to switch
1221     quickly among sounds) or i.e. loaded just on demand when the
1222     respective program change arrives (to safe RAM space), as well as a
1223     global volume factor for each entry, so the user can adjust the volume
1224     dynamic of his mapped instrument collection without having to modify
1225 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1226     MIDI instrument maps and assign each sampler channel individually
1227     a certain map, so that i.e. separation of normal instruments and
1228     drumkits is possible
1229 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1230     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1231 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1232     due to a constant size RingBuffer FIFO which is now replaced by a
1233     dynamic (unlimited) size std::list FIFO
1234 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1235     output channels for being processed by external effect processors
1236     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1237     controllers
1238 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1239 iliev 1130 - Implemented new, improved notification system
1240 schoenebeck 1149 - fixed compilation errors regarding OSX
1241     (patch by Toshi Nagata)
1242 iliev 1161 - implemented instruments database
1243 iliev 1345 - added support for escape sequences to the instruments database
1244 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1245     within the sampler's process (by using instrument editor plugins),
1246     you'll notice the new "Registered instrument editors:" message on
1247 schoenebeck 1407 startup, added a new LSCP command:
1248     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1249 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1250     given sampler channel, the plugin path can be overridden at compile
1251     time with ./configure --enable-plugin-dir=/some/dir
1252 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1253     in the sampler's process to safely edit instruments while playing
1254     without a crash (hopefully) by either suspending single regions
1255     wherever possible or if unavoidable whole engine(s)
1256 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1257     policy and priority on thread level, set a minimum stack size for
1258     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1259     threads simply inherited properties of starting thread instead of
1260     setting their own policy and priority
1261 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1262     main process did not wait for the stack trace process to finish
1263     its output
1264 persson 1248 - fixed some minor memory leaks
1265 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1266     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1267 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1268     register, to avoid relocations in the text segment at runtime)
1269 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1270 schoenebeck 947
1271     * MIDI driver:
1272     - dispatch bank select (MSB and LSB) messages
1273    
1274 schoenebeck 1049 * audio driver:
1275     - the ALSA audio output driver parameters now reflect the correct
1276     parameter value ranges for the respective selected sound card
1277     (patch by Till Wimmer, a bit fixed and extended)
1278    
1279 persson 951 * Gigasampler format engine:
1280     - if a filter is used and EG2 finishes before EG1, let the voice
1281     die when EG2 has finished (this fixes a problem with clicks and
1282     voice starvation for some gigs)
1283 persson 1038 - playback is no longer disabled during instrument loading
1284     - all notes playing on a channel that changes its instrument keep
1285     playing with the old instrument until they get a note off
1286     command
1287 persson 1039 - EG fix: a release value of zero could cause noises or crash
1288 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1289 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1290     above max sustain level, which means that there is a decay phase
1291     even if sustain is 100%
1292 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1293     noises or crashes
1294 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1295 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1296     supplied to the configure script (fixes #46)
1297 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1298     instead of a fix value
1299 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1300     127 (solo mode) only kill voices if the respective mode really
1301     changed
1302 persson 951
1303 schoenebeck 1244 * LSCP server:
1304     - fixed compile time error for old Bison versions
1305     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1306 schoenebeck 1245 - parser now supports extended ASCII character set
1307     (up to ASCII code 255, i.e. includes now umlauts and accents)
1308     - filename arguments in LSCP commands now allow to use escape
1309     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1310     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1311     code value like \xf2) (fixes bug #24)
1312 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1313     least one of their text-based parameters (i.e. name, description):
1314     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1315     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1316     "SET DB_INSTRUMENT_DIRECTORY NAME",
1317     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1318     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1319     "FIND DB_INSTRUMENT_DIRECTORIES"
1320 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1321     occured, the unexpected character and the actually expected, possible
1322     character(s), the latter only if less than 5 possibilities)
1323 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1324     settings
1325 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1326     of strings were treated as being one string containing commas
1327     (fixes #57)
1328 schoenebeck 1244
1329 iliev 959 * Bug fixes:
1330     - fixed crash occurring on certain LSCP scripts (Bug 39)
1331 persson 1038 - another thread safety fix for lscp "load engine" and "set
1332     channel audio output device"
1333 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1334     on a sampler channel with connected MIDI device
1335 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1336     device connected to a sampler channel to number less then or equal
1337     to the index of the port to which the sampler channel is connected.
1338 iliev 1296 - The previous bindings were not been disconnected when altering
1339     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1340     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1341 iliev 1297 - The active stream/voice count statistic was incorrect.
1342 iliev 1298 - notification events were not been sent for some sampler
1343     channel changes
1344 iliev 1305 - added default min and max values to restrict the number of allowed
1345     audio output channels and MIDI input ports
1346 iliev 1306 - the connection to the PCM interface is now closed when destroying
1347     an audio output device
1348 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1349 iliev 959
1350 schoenebeck 1221 * test cases:
1351     - updated and fixed (haven't been touched in a while)
1352    
1353 schoenebeck 937 Version 0.4.0 (24 November 2006)
1354 persson 696
1355 schoenebeck 697 * packaging changes:
1356 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1357     to post-(un)install steps; added devel package for liblinuxsampler;
1358     to linuxsampler.spec (RPM)
1359 schoenebeck 697 - install necessary development header files for allowing 3rd party
1360     applications to link against liblinuxsampler
1361     - liblinuxsampler's API documentation can be generated with 'make docs'
1362     (Doxygen required)
1363 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1364     implementation (currently either an integer math solution or a
1365     di-harmonic approximation), automatic detection can be overriden
1366     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1367     configure script argument though (mandatory for cross-compilation)
1368 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1369     provided some on his own (as CXXFLAGS)
1370 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1371     messages
1372 schoenebeck 852 - added compile time options to allow disabling the various audio and
1373     MIDI drivers
1374 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1375     (patch by Ebrahim Mayat)
1376 schoenebeck 697
1377 persson 696 * Gigasampler format engine:
1378 schoenebeck 738 - extensive synthesis optimization
1379     (reimplementation of EGs and LFO(s), removed synthesis parameter
1380     prerendering and the synthesis parameter matrix in general, splitting
1381     each audio fragment into subfragments now where each subfragment uses
1382 persson 830 constant pitch and filter coefficients. The volume coefficient is
1383     linearly interpolated inside a subfragment, unless
1384     --disable-interpolate-volume is set.)
1385 persson 696 - fine tuning of the EG modulation parameters
1386 persson 729 - improved filter cutoff calculation by adding support for the
1387     following gig parameters: Cutoff freq (used when no cutoff
1388     controller is defined), Control invert, Minimum cutoff, Velocity
1389 persson 791 curve and Velocity range. The keyboard tracking now scales
1390     cutoff frequency instead of resonance.
1391 persson 877 - added support for gig parameter Resonance.
1392 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1393 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1394     which can be overridden with --enable-global-attenuation
1395 persson 783 - EG fixes: made the length of "attack hold" stage more
1396     accurate. Release stage can now start before attack stage
1397 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1398     time now has a minimal value to prevent clicks.
1399 persson 799 - fixed pitch changes larger than one octave
1400 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1401     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1402     all modes can be altered via standard GM messages, that is CC5 for
1403     altering portamento time, CC65 for enabling / disabling portamento
1404     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1405 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1406     parameter) and crossfade
1407 persson 831 - added support for the "attenuation controller threshold" gig
1408     parameter
1409 persson 832 - added smoothing of volume changes caused by control change
1410     messages
1411 persson 865 - sample loop parameters are now taken from the DimensionRegion
1412     instead of the wave chunk
1413     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1414     not equal to a power of two
1415 persson 877 - reimplementation of the filter algorithm. The new filter is more
1416     accurate and supports all gig filter types, including bandreject
1417     and lowpass turbo.
1418 persson 903 - real support for 24 bit samples - samples are not truncated to
1419     16 bits anymore
1420     - support for aftertouch (channel pressure, not polyphonic
1421     aftertouch)
1422 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1423     amplifying from 0)
1424 persson 696
1425 schoenebeck 711 * LSCP server:
1426     - fixed application exit on broken pipe error (fixes bug #20)
1427 iliev 793 - fixed the notification messages delay due to lack of
1428     network activity (fixes bug #26)
1429 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1430     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1431 schoenebeck 711
1432 schoenebeck 838 * audio driver:
1433     - added aRts audio output driver (by no means RT safe)
1434    
1435 schoenebeck 775 * MIDI driver:
1436     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1437     messages several times instead of once
1438 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1439     for events (i.e. for offline rendering based MIDI drivers)
1440 persson 922 - added checks for bad MIDI data
1441 schoenebeck 775
1442 schoenebeck 900 * linuxsampler application:
1443     - show available sampler engine types on startup
1444    
1445 schoenebeck 705 * general changes:
1446     - support for muting sampler channels and solo mode of the same, two new
1447     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1448     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1449     introduced for this, the behavior is the same like on a mixer console
1450 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1451     --enable-process-muted-channels which can be used to enable the
1452     processing of muted channels.
1453 iliev 777 - support for sostenuto pedal
1454 iliev 779 - support for monitoring the total number of active voices
1455 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1456     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1457 persson 835 - fixed some memory management errors
1458 persson 841 - fixed some concurrency problems that could lead to crashes when
1459     LSCP commands were executed
1460 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1461     sampler channel (fixes bug #36)
1462 schoenebeck 705
1463 schoenebeck 692 Version 0.3.3 (15 July 2005)
1464 schoenebeck 686
1465     * packaging changes:
1466     - fixed compilation with gcc 4.0
1467    
1468 schoenebeck 687 * Gigasampler format engine:
1469     - LFO preprocessing was performed even though the respective LFO was
1470     disabled by the instrument patch (minor efficiency fix)
1471 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1472     for volume ramp downs in the same fragment (needed for current voice
1473     stealing implementation) then simply inform the user with a warning
1474     about possible click sounds and reduce the volume ramp down
1475     appropriately instead of cancelling the audio device connection
1476 schoenebeck 687
1477 schoenebeck 677 Version 0.3.2 (24 June 2005)
1478 schoenebeck 609
1479     * packaging changes:
1480     - updated autotools build files to compile on OS X
1481     (conditional compilation of CoreMIDI and MidiShare drivers)
1482 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1483     './configure --disable-asm' (definitely not recommended)
1484 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1485     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1486     (due to 'dist-bzip2' automake option)
1487 schoenebeck 649
1488     * Gigasampler format engine:
1489     - support for the gig parameters for "release velocity response" curves
1490     - fine tuning of the EGADSR envelope
1491     - volume of release triggered samples now depends on note-on velocity,
1492     note length and gig parameter "release trigger decay" instead of
1493     note-off velocity.
1494 schoenebeck 663 - revised voice stealing
1495     (fixes crash and endless loop caused by voice stealing)
1496 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1497 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1498     instead of when the respective voice is actually launched
1499     (fixes undefined behavior if stolen voices belonged to a key group -
1500     this case was followed by a "killed voice survived" error message)
1501 schoenebeck 669 - fixed minor issue with null/silence samples
1502     (those stole voices even though they don't need a voice at all which
1503     resulted in "voice stealing didn't work out" messages)
1504 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1505     instrument or audio output device change
1506 schoenebeck 654
1507 schoenebeck 620 * LSCP server:
1508 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1509 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1510 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1511 schoenebeck 609
1512 schoenebeck 668 * linuxsampler application:
1513     - added command line parameters --lscp-addr and --lscp-port to override
1514     default IP address and port of LSCP server
1515    
1516 schoenebeck 579 Version 0.3.1 (24 May 2005)
1517    
1518     * initial release
