NKSP: Introducing variable return type for built-in functions.

* Changed method signature VMFunction::returnType() ->
  VMFunction::returnType(VMFnArgs* args) to allow built-in
  functions to proclaim a different result value type depending
  on the arguments to be passed to the function.

* Built-in script function abs() optionally accepts and returns
  real number.

* Built-in script functions min() and max() optionally accept
  real number arguments and return real number as result in that
  case.

* Added real number test cases for the built-in abs(), min() and
  max() functions.

* Bumped version (2.1.1.svn7).

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 3577 - Built-in script functions may have a different return type depending on
56     the arguments passed to the function.
57     - Built-in script function "abs()" optionally accepts and returns real
58     number.
59     - Built-in script functions "min()" and "max()" optionally accept real
60     number arguments and return real number as result in that case.
61 schoenebeck 3551
62 schoenebeck 3550 * test cases:
63 schoenebeck 3548 - Fixed compiler errors in test cases.
64     - Updated README for how to compile & run test cases.
65     - Updated test case
66     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
67     expected behaviour of the Mutex class implementation (recursive
68     mutex type).
69 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
70     functions.
71 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
72 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
73     int_to_real(), real(), real_to_int() and int(), as well as for the
74     plus, minus and negate language operators.
75 schoenebeck 3548
76 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
77 schoenebeck 3381
78     * Real-time instrument scripts:
79     - Fixed behavior of built-in NKSP functions change_sustain(),
80     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
81     and change_cutoff_release().
82    
83 schoenebeck 3444 * general changes:
84     - Only play release trigger samples on sustain pedal up if this behaviour
85     was explicitly requested by the instrument (otherwise only on note-off).
86 persson 3455 - Fixed compiler warnings.
87     - Fixed compilation error when cross-compiling to Mac.
88 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
89     (see bug #169).
90     - LSCP doc: Be more clear describing the two distinct approaches
91     of using external vs. internal effects (see bug #169).
92 schoenebeck 3514 - "optional" class: Fixed comparison operators.
93 schoenebeck 3444
94 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
95     - Format extension: If requested by instrument then don't play release
96     trigger sample on note-off events.
97    
98 schoenebeck 3487 * SFZ format engine:
99     - Fixed memory leak when releasing samples
100     (fixes bug #307, patch by Jacek Roszkowski)
101 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
102     (fixes bug #308, patch by Jacek Roszkowski).
103 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
104     (fixes bug #310, patch by Jacek Roszkowski).
105 schoenebeck 3487
106 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
107 persson 2837
108 persson 2856 * SFZ format engine:
109     - added support for <global>, <master> and #define (patch by Alby M)
110 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
111     - Added support for sfz extension opcode 'script' which may be used to
112     load real-time instrument script file (NKSP script language).
113 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
114 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
115 persson 3291 - sfz parser: allow missing space between header and opcode
116 persson 2856
117 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
118 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
119     cutoff settings.
120 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
121     all if an up-pitch of more than 40 semi tones was requested (I don't
122     think there is any stock gig sound that requires this behavior to
123     resemble its original sound).
124 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
125     be aborted (as LinuxSampler extension to the original GigaStudio 4
126     format).
127 schoenebeck 3072
128 persson 2837 * general changes:
129     - fixed printf type errors (mostly in debug messages)
130 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
131 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
132     allowing to sort data efficiently in real-time safe manner.
133     - RTList class: added methods for moving/inserting elements to arbitrary
134     position within a list.
135     - RTList class: added method fromPtr() for creating an Iterator object from
136     a raw element pointer.
137     - Attempt to partly fix resetting engine channels vs. resetting engine, an
138     overall cleanup of the Reset*(), ConnectAudioDevice(),
139     DisconnectAudioDevice() API methods would still be desirable though,
140     because the current situation is still inconsistent and error prone.
141 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
142     being directly assigned to a keyboard key. This allows more fine graded
143     processing of voices, which is i.e. required for certain instrument
144     script features.
145 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
146     (CC #64) events.
147     - Fix: Release trigger voices can now also distinguish correctly between
148     note-off and sustain pedal up events.
149 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
150     (while slow rate of crossfade smoother is preserved) to allow quick
151     volume and pan changes by instrument scripts for instance.
152 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
153     properly and thus were ignored for certain uses.
154 schoenebeck 3018 - Added new C++ API method
155     VirtualMidiDevice::SendChannelPressureToSampler().
156 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
157     sub threads is 16-byte aligned
158 schoenebeck 3054 - fixed numerous compiler warnings
159 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
160 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
161     fixes potential undefined behavior.
162 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
163     have a valid sample mapped (fixes bug #252).
164     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
165 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
166     subsequent optional argument due to glibc's implementation oddity
167     which expects a "=" sign, but no space between them.
168 persson 2837
169 schoenebeck 2866 * packaging changes:
170     - removed unnecessary dependency to libuuid
171     (originated by libgig's usage of it)
172 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
173     auto detect whether it (sh/c)ould output its messages in color.
174 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
175     substitution variable.
176     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
177 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
178     linuxsampler with instruments DB support.
179 schoenebeck 2866
180 schoenebeck 2871 * Real-time instrument scripts:
181     - Implemented scheduler for delayed MIDI events and for suspended scripts.
182     - Built-in script function "wait()": implemented support for function's
183     "duration-us" argument, thus scripts using this function are now
184     correctly resumed after the requested amount of microseconds.
185     - Built-in script function "play_note()": implemented support for
186     function's "duration-us" argument, thus notes triggered with this
187     argument are now correctly released after the requested amount of
188     microseconds.
189     - Fix: script events were not cleared when engine channel was reset,
190     potentially causing undefined behavior.
191     - Fixed crash which happened when trying to reference an undeclared
192     variable.
193 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
194     special value -1 for "duration-us" argument, which will cause the
195     triggered note to be released once the original note was released.
196 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
197     - Added new API method ScriptVM::syntaxHighlighting() which provides
198     a convenient syntax highlighting backend for external instrument
199     script editor applications.
200 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
201     - Extended parser issues to provide not only first line and first
202     column, but also last line and last column of issue (thus marking
203     the precise span of the issue within the source code).
204 schoenebeck 2902 - Reload script automatically after being modified by an instrument
205     editor.
206 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
207     like "on note end on".
208 schoenebeck 2931 - Implemented built-in script function "change_vol()".
209     - Implemented built-in script function "change_tune()".
210     - Implemented built-in script function "change_pan()".
211 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
212     - Implemented built-in script function "change_reso()".
213     - Implemented built-in script function "event_status()".
214     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
215     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
216     "event_status()" function.
217     - NKSP language: Added support for bitwise operators ".or.", ".and."
218     and ".not.".
219     - NKSP language scanner: Fixed IDs matching to require at least one
220     character (i.e. when matching function names or variable names).
221     - NKSP language scanner: disabled unusued rules.
222 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
223     be distinguished engine internally from "real" MIDI note on/off
224     events in order to avoid misbehaviors like hanging notes.
225 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
226     - Implemented built-in script variable "$NKSP_REAL_TIMER".
227     - Implemented built-in script variable "$NKSP_PERF_TIMER".
228     - Implemented built-in script variable "$ENGINE_UPTIME".
229 schoenebeck 2945 - Implemented built-in script function "inc()".
230     - Implemented built-in script function "dec()".
231     - NKSP language fix: division expressions were evaluated too often.
232     - NKSP language fix: string concatenation operator was right
233     associative instead of left (to right).
234 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
235     (i.e. "if end if").
236 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
237     - Implemented built-in script variable "$NI_CALLBACK_ID".
238     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
239     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
240     - Added support for read-only built-in variables (respectively
241     handled by the script parser).
242     - Added built-in script constant "$NI_CB_TYPE_INIT".
243     - Added built-in script constant "$NI_CB_TYPE_NOTE".
244     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
245     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
246 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
247 schoenebeck 2953 - Implemented built-in script function "change_attack()".
248     - Implemented built-in script function "change_decay()".
249     - Implemented built-in script function "change_release()".
250 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
251     synthesis parameter changes immediately in case the respective note
252     was triggered at the same time, instead of scheduling the parameter
253     change, especially because it would cause some parameter types's
254     changes either to be ramped (i.e. change_vol()) or other types even
255     to have not effect at all (i.e. change_attack()).
256 schoenebeck 2965 - Implemented built-in script function "sh_left()".
257     - Implemented built-in script function "sh_right()".
258 schoenebeck 2970 - Implemented built-in script function "min()".
259     - Implemented built-in script function "max()".
260 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
261     was loaded.
262     - NKSP built-in wait() script function: abort script execution if
263     a negative or zero wait time was passed as argument (since this is
264     a common indication of a bug either of the script or even of the
265     engine, which could lead to RT instability or even worse).
266 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
267     threatening scripts.
268 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
269 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
270     initializer list to an array variable.
271 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
272 schoenebeck 3076 - Implemented built-in script function "in_range()".
273 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
274     - Implemented built-in script function "change_amp_lfo_freq()".
275     - Implemented built-in script function "change_pitch_lfo_depth()".
276     - Implemented built-in script function "change_pitch_lfo_freq()".
277 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
278     - Implemented built-in script function "change_tune_time()".
279     - Implemented built-in script function "fade_in()".
280     - Implemented built-in script function "fade_out()".
281     - Fixed acceptance of wrong data type of parameters passed to built-in
282     script functions "change_vol()", "change_tune()", "change_pan()",
283     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
284     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
285     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
286 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
287     of its possible parameter selections.
288     - Added built-in script function "set_event_par()" and implemented some
289     of its possible parameter selections.
290 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
291 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
292 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
293     built-in function "ignore_controller()".
294 schoenebeck 3214 - Implemented built-in script function "change_velo()".
295     - Implemented built-in script function "change_note()".
296 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
297     intuitive behavior if used in combination with "change_vol_time()" or
298     "change_tune_time()" respectively: now tuning/volume changes are only
299     assigned (without delay) immediately to a new note if the respective
300     timing function has not been called before, otherwise the volume/tuning
301     changes are automatically faded (before, only the event's time stamp was
302     relevant).
303 schoenebeck 3221 - Implemented built-in script function "array_equal()".
304     - Implemented built-in script function "search()".
305     - Implemented built-in script function "sort()".
306     - NKSP Fix: Never suspend "init" event handlers.
307 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
308     available for gig format engine).
309 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
310     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
311     - Implemented built-in script function "change_vol_curve()".
312     - Implemented built-in script function "change_tune_curve()".
313 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
314     offset with argument 3, where special value -1 means to use the regular
315     sample offset as defined by the instrument file.
316 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
317     - Built-in variable $EVENT_NOTE is now a read-only variable.
318     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
319     - built-in "play_note()" function now accepts -2 for its fourth argument
320     (note duration) which means the life time of the note shall be sticked
321     to the requested note number of argument 1.
322     - Fix: built-in "play_note()" function now returns 0 as result value if
323     -1 was passed for its fourth argument (note duration) and the respective
324     parent note is already gone.
325 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
326 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
327     - NKSP language: Raise parser warning if array variable is accessed with
328     an index that exceeds the array's size.
329 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
330 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
331     code blocks.

333     another script handler by passing its callback ID.
334 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
335     "init" event handlers.
336 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
337     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
338     to retrieve all code blocks filtered out by the preprocessor.
339 schoenebeck 3293 - Added built-in script function "fork()".
340     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
341     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
342     - Fixed potential crash when accessing dynamic built-in array variables.
343 schoenebeck 3296 - Added built-in script function "callback_status()".
344     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
345     - Added built-in constant $CALLBACK_STATUS_QUEUE.
346     - Added built-in constant $CALLBACK_STATUS_RUNNING.
347 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
348     "change_decay()" and "change_release()" to i.e. allow passing 2000000
349     for doubling the respective time.
350 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
351     to a lexer start condition stack underrun.
352     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
353     USE_CODE_IF_NOT() preprocessor statements.
354 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
355     can be set to disable all subsequent built-in "message()" function calls
356     on preprocessor level.
357 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
358 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
359     to avoid the editor app to crash on ill-formed text input.

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

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

913     (fixes #208)
914 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
915     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
916     practically irrelevant, however it caused problems with the new LSCP
917     shell's auto completion feature).
918 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
919     after each other (fixes #231).

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

1055 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1056     respective FX send MIDI controller was used
1057 schoenebeck 1724 - added support for GM global device volume SysEx message
1058 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1059     whole sampler [default] or only to the sampler channels that are
1060     connected to the respective MIDI input port the SysEx message arrived
1061     on)
1062 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1063     sometimes wrongly killed in the same buffer, causing no sound to
1064     be played
1065 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1066     which is usally used to switch a part between chromatic sounds and
1067     drumkit sounds (as opposed to their common default setting of MIDI
1068     part 10 being a drumkit part and all other ones chromatic parts), in
1069     LS however one can switch between the first 16 MIDI instrument maps
1070     defined for the sampler
1071 persson 1764 - made it possible to create multiple sample channels even if the
1072     audio thread isn't running
1073 persson 1844 - fixed crash when removing channel with active voices (#116)
1074 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1075     un-cache the respective sample if it's really not used by any
1076     sampler engine anymore
1077     - re-cache samples in case they were changed by an instrument editor,
1078     e.g. when a sample was added while playing (#82)
1079 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1080     same time stamp as the voice's note-on event and occured both in the
1081     same audio fragment cycle (fixes bug #112)
1082 persson 1858 - added support for the "fine tune" and "pitch bend range"
1083     instrument-level gig parameters
1084     - fixed minor artifacts in pitch bend handling
1085 schoenebeck 1860 - added support for GS Reset SysEx message
1086 persson 1862 - allow gig files to use unlimited downward pitch shifting
1087     - added a limit check for upward pitch shifting
1088 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1089     note was silent
1090 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1091     same time a new instrument was loading
1092 persson 1644
1093 schoenebeck 1687 * LSCP server:
1094     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1095     react on MIDI data arriving on certain sampler channels (so far only
1096     Note-On and Note-Off events are sent via this LSCP event)
1097 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1098     react on MIDI data arriving on certain MIDI input devices (so far only
1099     Note-On and Note-Off events are sent via this LSCP event)
1100 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1101     SET DB_INSTRUMENT FILE_PATH
1102 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1103     frontends to send MIDI messages to specific sampler channel
1104     - added two additional fields to GET FILE INSTRUMENT INFO command -
1105     KEY_BINDINGS and KEYSWITCH_BINDINGS
1106 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1107     was incorrect
1108 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1109 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1110     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1111     be triggered respectively
1112     - added new LSCP command "SET STREAMS" to globally alter the maximum
1113     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1114     which will be triggered respectively
1115 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1116     a gigedit file dialog is opened)
1117 iliev 1848 - close all connections when LSCPServer is deleted
1118 iliev 1882 - hard close of all sockets on exit
1119 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1120     driver
1121 schoenebeck 1687
1122 iliev 1761 * Bug fixes:
1123     - fixed a crash which occurs when removing a sampler channel waiting
1124     to start instrument loading after another channel
1125 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1126     instrument loading in progress (bug #113)
1127 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1128     instrument with PERSISTENT load mode
1129 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1130     - fixed memory leaks when issuing the following LSCP commands:
1131     GET AUDIO_OUTPUT_DRIVER INFO
1132     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1133     GET MIDI_INPUT_DRIVER INFO
1134     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1135     - fixed possible compilation error when sqlite is not present
1136 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1137 iliev 1847 - fixed crash when changing the audio output device of a sampler
1138     channel with loaded instrument and start playing notes
1139 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1140 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1141     PowerPC, which probably could cause crashes on that platform
1142 persson 1889 - fixed a memory management error which could cause a crash when a
1143     plugin was unloaded
1144 persson 1896 - bugfix: two private structs had the same name, which could cause
1145     problems if the linker chose the wrong constructor
1146 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1147     Windows
1148 iliev 1761

1150 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1151 schoenebeck 1454
1152     * packaging changes:
1153     - added autoconf checks for pthread library
1154     - added autoconf check for pthread bug found on certain NPTL-enabled
1155     glibc versions (see Gentoo bug report #194076)
1156 senoner 1502 - added autoconf checks for MS Windows
1157 schoenebeck 1454
1158 persson 1455 * general changes:
1159     - bugfix: the thread used by an editor plugin didn't die when the
1160     editor closed
1161 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1162     out all the space. operator--() did not apply size_mask after
1163     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1164     order to avoid problems with the _NonVolatileReader functions.
1165     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1166     GetWriteSpace(). Since this function is currently only used in
1167     the stream's qsort() compare function, it didn't trigger any
1168     bugs.
1169     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1170     24bit mode too. Faster method to read 24bit words on little
1171     endian machines (x86): replaced 3 byte reads + shifts with a 1
1172     unaligned 32bit read and shift
1173     - experimental support for MS Windows (MIDI input via MME, AUDIO
1174     output via ASIO)
1175     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1176 iliev 1541 - support for monitoring the total number of active disk streams
1177     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1178     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1179 persson 1455
1180 senoner 1500 * AUDIO driver:
1181 persson 1534 - added Windows ASIO low latency audio driver
1182 senoner 1500
1183 senoner 1485 * MIDI driver:
1184 schoenebeck 1495 - added MME Windows MIDI driver
1185 senoner 1485
1186 schoenebeck 1471 * LSCP server:
1187     - added support for Windows style path / filenames, however with
1188     forward slash path separators instead of backslash
1189     (i.e. "C:/foo/bar.gig")
1190 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1191     apostrophes as well
1192 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1193     "LIST FILE INSTRUMENTS <file>" and
1194     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1195     about an arbitrary instrument file on the system where the sampler is
1196     running on
1197 schoenebeck 1471
1198 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1199 schoenebeck 947
1200 schoenebeck 1065 * packaging changes:
1201 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1202     API header files anymore
1203 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1204     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1205 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1206     capable to execute our autoconf environment, thus no need anymore
1207     to maintain the compile time configuration file (osx/version.h) for
1208     OSX manually (patch by Toshi Nagata)
1209 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1210     parameters
1211 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1212     C++ API header files, all implementation internal global definitions
1213     are now in global_private.h
1214     - atomic.h is not exposed to the C++ API anymore
1215     - no need to include config.h anymore for using LS's API header files
1216     - fixed warnings in API doc generation
1217 schoenebeck 1065
1218 schoenebeck 947 * general changes:
1219     - replaced the old, confusing MIDI program change mechanism by a
1220     flexible MIDI instrument mapper which allows to map arbitrary
1221 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1222 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1223     loaded on the respective channel when such MIDI program change
1224     messages arrive, beside that, each entry allows to define a life-time
1225     strategy for the instrument, so the user can define whether the
1226     instrument should i.e. be permanently loaded (to be able to switch
1227     quickly among sounds) or i.e. loaded just on demand when the
1228     respective program change arrives (to safe RAM space), as well as a
1229     global volume factor for each entry, so the user can adjust the volume
1230     dynamic of his mapped instrument collection without having to modify
1231 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1232     MIDI instrument maps and assign each sampler channel individually
1233     a certain map, so that i.e. separation of normal instruments and
1234     drumkits is possible
1235 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1236     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1237 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1238     due to a constant size RingBuffer FIFO which is now replaced by a
1239     dynamic (unlimited) size std::list FIFO
1240 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1241     output channels for being processed by external effect processors
1242     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1243     controllers
1244 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1245 iliev 1130 - Implemented new, improved notification system
1246 schoenebeck 1149 - fixed compilation errors regarding OSX
1247     (patch by Toshi Nagata)
1248 iliev 1161 - implemented instruments database
1249 iliev 1345 - added support for escape sequences to the instruments database
1250 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1251     within the sampler's process (by using instrument editor plugins),
1252     you'll notice the new "Registered instrument editors:" message on
1253 schoenebeck 1407 startup, added a new LSCP command:
1254     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1255 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1256     given sampler channel, the plugin path can be overridden at compile
1257     time with ./configure --enable-plugin-dir=/some/dir
1258 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1259     in the sampler's process to safely edit instruments while playing
1260     without a crash (hopefully) by either suspending single regions
1261     wherever possible or if unavoidable whole engine(s)
1262 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1263     policy and priority on thread level, set a minimum stack size for
1264     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1265     threads simply inherited properties of starting thread instead of
1266     setting their own policy and priority
1267 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1268     main process did not wait for the stack trace process to finish
1269     its output
1270 persson 1248 - fixed some minor memory leaks
1271 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1272     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1273 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1274     register, to avoid relocations in the text segment at runtime)
1275 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1276 schoenebeck 947
1277     * MIDI driver:
1278     - dispatch bank select (MSB and LSB) messages
1279    
1280 schoenebeck 1049 * audio driver:
1281     - the ALSA audio output driver parameters now reflect the correct
1282     parameter value ranges for the respective selected sound card
1283     (patch by Till Wimmer, a bit fixed and extended)
1284    
1285 persson 951 * Gigasampler format engine:
1286     - if a filter is used and EG2 finishes before EG1, let the voice
1287     die when EG2 has finished (this fixes a problem with clicks and
1288     voice starvation for some gigs)
1289 persson 1038 - playback is no longer disabled during instrument loading
1290     - all notes playing on a channel that changes its instrument keep
1291     playing with the old instrument until they get a note off
1292     command
1293 persson 1039 - EG fix: a release value of zero could cause noises or crash
1294 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1295 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1296     above max sustain level, which means that there is a decay phase
1297     even if sustain is 100%
1298 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1299     noises or crashes
1300 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1301 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1302     supplied to the configure script (fixes #46)
1303 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1304     instead of a fix value
1305 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1306     127 (solo mode) only kill voices if the respective mode really
1307     changed
1308 persson 951
1309 schoenebeck 1244 * LSCP server:
1310     - fixed compile time error for old Bison versions
1311     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1312 schoenebeck 1245 - parser now supports extended ASCII character set
1313     (up to ASCII code 255, i.e. includes now umlauts and accents)
1314     - filename arguments in LSCP commands now allow to use escape
1315     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1316     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1317     code value like \xf2) (fixes bug #24)
1318 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1319     least one of their text-based parameters (i.e. name, description):
1320     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1321     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1322     "SET DB_INSTRUMENT_DIRECTORY NAME",
1323     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1324     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1325     "FIND DB_INSTRUMENT_DIRECTORIES"
1326 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1327     occured, the unexpected character and the actually expected, possible
1328     character(s), the latter only if less than 5 possibilities)
1329 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1330     settings
1331 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1332     of strings were treated as being one string containing commas
1333     (fixes #57)
1334 schoenebeck 1244
1335 iliev 959 * Bug fixes:
1336     - fixed crash occurring on certain LSCP scripts (Bug 39)
1337 persson 1038 - another thread safety fix for lscp "load engine" and "set
1338     channel audio output device"
1339 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1340     on a sampler channel with connected MIDI device
1341 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1342     device connected to a sampler channel to number less then or equal
1343     to the index of the port to which the sampler channel is connected.
1344 iliev 1296 - The previous bindings were not been disconnected when altering
1345     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1346     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1347 iliev 1297 - The active stream/voice count statistic was incorrect.
1348 iliev 1298 - notification events were not been sent for some sampler
1349     channel changes
1350 iliev 1305 - added default min and max values to restrict the number of allowed
1351     audio output channels and MIDI input ports
1352 iliev 1306 - the connection to the PCM interface is now closed when destroying
1353     an audio output device
1354 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1355 iliev 959
1356 schoenebeck 1221 * test cases:
1357     - updated and fixed (haven't been touched in a while)
1358    
1359 schoenebeck 937 Version 0.4.0 (24 November 2006)
1360 persson 696
1361 schoenebeck 697 * packaging changes:
1362 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1363     to post-(un)install steps; added devel package for liblinuxsampler;
1364     to linuxsampler.spec (RPM)
1365 schoenebeck 697 - install necessary development header files for allowing 3rd party
1366     applications to link against liblinuxsampler
1367     - liblinuxsampler's API documentation can be generated with 'make docs'
1368     (Doxygen required)
1369 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1370     implementation (currently either an integer math solution or a
1371     di-harmonic approximation), automatic detection can be overriden
1372     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1373     configure script argument though (mandatory for cross-compilation)
1374 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1375     provided some on his own (as CXXFLAGS)
1376 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1377     messages
1378 schoenebeck 852 - added compile time options to allow disabling the various audio and
1379     MIDI drivers
1380 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1381     (patch by Ebrahim Mayat)
1382 schoenebeck 697
1383 persson 696 * Gigasampler format engine:
1384 schoenebeck 738 - extensive synthesis optimization
1385     (reimplementation of EGs and LFO(s), removed synthesis parameter
1386     prerendering and the synthesis parameter matrix in general, splitting
1387     each audio fragment into subfragments now where each subfragment uses
1388 persson 830 constant pitch and filter coefficients. The volume coefficient is
1389     linearly interpolated inside a subfragment, unless
1390     --disable-interpolate-volume is set.)
1391 persson 696 - fine tuning of the EG modulation parameters
1392 persson 729 - improved filter cutoff calculation by adding support for the
1393     following gig parameters: Cutoff freq (used when no cutoff
1394     controller is defined), Control invert, Minimum cutoff, Velocity
1395 persson 791 curve and Velocity range. The keyboard tracking now scales
1396     cutoff frequency instead of resonance.
1397 persson 877 - added support for gig parameter Resonance.
1398 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1399 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1400     which can be overridden with --enable-global-attenuation
1401 persson 783 - EG fixes: made the length of "attack hold" stage more
1402     accurate. Release stage can now start before attack stage
1403 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1404     time now has a minimal value to prevent clicks.
1405 persson 799 - fixed pitch changes larger than one octave
1406 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1407     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1408     all modes can be altered via standard GM messages, that is CC5 for
1409     altering portamento time, CC65 for enabling / disabling portamento
1410     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1411 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1412     parameter) and crossfade
1413 persson 831 - added support for the "attenuation controller threshold" gig
1414     parameter
1415 persson 832 - added smoothing of volume changes caused by control change
1416     messages
1417 persson 865 - sample loop parameters are now taken from the DimensionRegion
1418     instead of the wave chunk
1419     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1420     not equal to a power of two
1421 persson 877 - reimplementation of the filter algorithm. The new filter is more
1422     accurate and supports all gig filter types, including bandreject
1423     and lowpass turbo.
1424 persson 903 - real support for 24 bit samples - samples are not truncated to
1425     16 bits anymore
1426     - support for aftertouch (channel pressure, not polyphonic
1427     aftertouch)
1428 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1429     amplifying from 0)
1430 persson 696
1431 schoenebeck 711 * LSCP server:
1432     - fixed application exit on broken pipe error (fixes bug #20)
1433 iliev 793 - fixed the notification messages delay due to lack of
1434     network activity (fixes bug #26)
1435 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1436     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1437 schoenebeck 711
1438 schoenebeck 838 * audio driver:
1439     - added aRts audio output driver (by no means RT safe)
1440    
1441 schoenebeck 775 * MIDI driver:
1442     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1443     messages several times instead of once
1444 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1445     for events (i.e. for offline rendering based MIDI drivers)
1446 persson 922 - added checks for bad MIDI data
1447 schoenebeck 775
1448 schoenebeck 900 * linuxsampler application:
1449     - show available sampler engine types on startup
1450    
1451 schoenebeck 705 * general changes:
1452     - support for muting sampler channels and solo mode of the same, two new
1453     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1454     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1455     introduced for this, the behavior is the same like on a mixer console
1456 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1457     --enable-process-muted-channels which can be used to enable the
1458     processing of muted channels.
1459 iliev 777 - support for sostenuto pedal
1460 iliev 779 - support for monitoring the total number of active voices
1461 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1462     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1463 persson 835 - fixed some memory management errors
1464 persson 841 - fixed some concurrency problems that could lead to crashes when
1465     LSCP commands were executed
1466 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1467     sampler channel (fixes bug #36)
1468 schoenebeck 705
1469 schoenebeck 692 Version 0.3.3 (15 July 2005)
1470 schoenebeck 686
1471     * packaging changes:
1472     - fixed compilation with gcc 4.0
1473    
1474 schoenebeck 687 * Gigasampler format engine:
1475     - LFO preprocessing was performed even though the respective LFO was
1476     disabled by the instrument patch (minor efficiency fix)
1477 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1478     for volume ramp downs in the same fragment (needed for current voice
1479     stealing implementation) then simply inform the user with a warning
1480     about possible click sounds and reduce the volume ramp down
1481     appropriately instead of cancelling the audio device connection
1482 schoenebeck 687
1483 schoenebeck 677 Version 0.3.2 (24 June 2005)
1484 schoenebeck 609
1485     * packaging changes:
1486     - updated autotools build files to compile on OS X
1487     (conditional compilation of CoreMIDI and MidiShare drivers)
1488 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1489     './configure --disable-asm' (definitely not recommended)
1490 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1491     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1492     (due to 'dist-bzip2' automake option)
1493 schoenebeck 649
1494     * Gigasampler format engine:
1495     - support for the gig parameters for "release velocity response" curves
1496     - fine tuning of the EGADSR envelope
1497     - volume of release triggered samples now depends on note-on velocity,
1498     note length and gig parameter "release trigger decay" instead of
1499     note-off velocity.
1500 schoenebeck 663 - revised voice stealing
1501     (fixes crash and endless loop caused by voice stealing)
1502 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1503 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1504     instead of when the respective voice is actually launched
1505     (fixes undefined behavior if stolen voices belonged to a key group -
1506     this case was followed by a "killed voice survived" error message)
1507 schoenebeck 669 - fixed minor issue with null/silence samples
1508     (those stole voices even though they don't need a voice at all which
1509     resulted in "voice stealing didn't work out" messages)
1510 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1511     instrument or audio output device change
1512 schoenebeck 654
1513 schoenebeck 620 * LSCP server:
1514 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1515 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1516 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1517 schoenebeck 609
1518 schoenebeck 668 * linuxsampler application:
1519     - added command line parameters --lscp-addr and --lscp-port to override
1520     default IP address and port of LSCP server
1521    
1522 schoenebeck 579 Version 0.3.1 (24 May 2005)
1523    
1524     * initial release
