File size: 88079 byte(s)
* NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
  evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
  evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
  as convenient methods for automatically converting values to expected
  metric value basis.

* NKSP built-in function "wait()" accepts now both integers and real numbers
  as argument.

* Bumped version (2.1.1.svn9).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++14 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++14 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++14).
10 - 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
14 * 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 - 64 bit support for NKSP integer scripts variables (declare $foo).
21 - 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 - NKSP script editor API: Added support for detecting standard unit tokens
40 and their potential metric prefix token.
41 - 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 - Allow built-in exit() function to potentially accept real number type
54 argument as well.
55 - 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 - NKSP VM API: Allow units and 'final'ness to be returned as result from
62 built-in functions (added methods VMFunction::returnUnitType() and
63 VMFunction::returnsFinal() for that purpose which must be implemented by
64 built-in function implementations).
65 - NKSP language: Allow metric unit prefixes of numeric scalar and array
66 variables to be changed freely at runtime (unlike unit types like Hz etc.
67 which are still sticky, parse-time features of variables which cannot be
68 changed at runtime for the intentional sake of determinism).
69 - NKSP language: 'final' values are prohibited for array variables for now
70 (attempt causes a parsers error).
71 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
72 conditions of runtime control structures like if(), while(), select()
73 (attempt causes a parser error).
74 - NKSP VM API: Allow built-in functions to perform their own, individual
75 parse time checks of arguments going to be passed to the function at
76 runtime (added method VMFunction::checkArgs() for that purpose).
77 - NKSP language: raise parser warning if only one operand of binary
78 operators (like logical 'or' comparison) contain a 'final' value (because
79 it would always yield in a 'final' result in such cases).
80 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
81 different metric unit prefixes, which will behave as expected (e.g.
82 result of expression '1000us < 2ms' is true).
83 - NKSP language: Allow adding values with different metric unit prefixes
84 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
85 - NKSP language: Allow subtracting values with different metric unit
86 prefixes (e.g. result of expression '1ms - 20us' is '980us').
87 - NKSP language: Allow multiplying with any metric unit prefixes
88 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
89 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
90 we don't have any considerable practical use for a term like '4s^2'
91 (hence any attempt multiplying two unit types still causes parser error).
92 - NKSP language: Allow dividing by any metric unit prefixes and allow
93 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
94 yields in unit free result '8'). So this is now a way to cast units away
95 e.g. for passing the result to other expressions, certain function calls
96 or variables which are not accepting any units (or that specific unit).
97 - NKSP language: integer arrays and real number arrays can now be converted
98 to strings (e.g. for dumping their content with message() calls for
99 script debugging purposes).
100 - NKSP language: expressions and variables with units are now correctly
101 casted to strings (e.g. with message() calls).
102 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
103 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
104 floating point tolerances into account.
105 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
106 VMScalarNumberExpr::evalCastReal().
107 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
108 'VMIntArrayExpr' and 'VMRealArrayExpr'.
109 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
110 unitFactor() (runtime) methods.
111 - Built-in function "exit()" supports now returning units and 'final'ness
112 for test cases.
113 - The following built-in functions support now units as well: "abs()",
114 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
115 "real_to_int()", "int()", "int_to_real()" and "real()".
116 - Built-in functions "array_equal()", "search()" and "sort()" support now
117 real number arrays (correctly) as well.
118 - Added individual parse time checks of arguments to be passed to built-in
119 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
120 "array_equal()" and "search()" specific for their individual purposes.
121 - NKSP VM refactoring: Renamed all methods, functions and classes matching
122 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
123 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
124 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
125 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
126 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
127 isScalarNumber() -> isNumber()).
128 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
129 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
130 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
131 as convenient methods for automatically converting values to expected
132 metric value basis.
133 - Built-in function "wait()" accepts now both integers and real numbers as
134 argument.
135
136 * test cases:
137 - Fixed compiler errors in test cases.
138 - Updated README for how to compile & run test cases.
139 - Updated test case
140 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
141 expected behaviour of the Mutex class implementation (recursive
142 mutex type).
143 - Added test cases for NKSP core language aspects and core built-in
144 functions.
145 - Fixed thread tests segfaulting on Linux.
146 - NKSP: Added real number test cases for built-in functions exit(),
147 int_to_real(), real(), real_to_int() and int(), as well as for the
148 plus, minus and negate language operators.
149 - Added massive amount of NKSP test cases for standard measuring units and
150 'final' operator usage cases.
151 - Added NKSP test cases for (floating point tolerance aware) real number
152 equalness / unequalness comparison.
153
154 Version 2.1.1 (27 Jul 2019)
155
156 * Real-time instrument scripts:
157 - Fixed behavior of built-in NKSP functions change_sustain(),
158 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
159 and change_cutoff_release().
160
161 * general changes:
162 - Only play release trigger samples on sustain pedal up if this behaviour
163 was explicitly requested by the instrument (otherwise only on note-off).
164 - Fixed compiler warnings.
165 - Fixed compilation error when cross-compiling to Mac.
166 - FX Sends: Provide more useful error messages on routing problems
167 (see bug #169).
168 - LSCP doc: Be more clear describing the two distinct approaches
169 of using external vs. internal effects (see bug #169).
170 - "optional" class: Fixed comparison operators.
171
172 * Gigasampler/GigaStudio format engine:
173 - Format extension: If requested by instrument then don't play release
174 trigger sample on note-off events.
175
176 * SFZ format engine:
177 - Fixed memory leak when releasing samples
178 (fixes bug #307, patch by Jacek Roszkowski)
179 - Fixed potential crash when a sample is shared by more than one region
180 (fixes bug #308, patch by Jacek Roszkowski).
181 - Opcode 'sample': Added support for built-in sample '*silence'
182 (fixes bug #310, patch by Jacek Roszkowski).
183
184 Version 2.1.0 (25 Nov 2017)
185
186 * SFZ format engine:
187 - added support for <global>, <master> and #define (patch by Alby M)
188 - Removed code duplication in SFZ file loading code.
189 - Added support for sfz extension opcode 'script' which may be used to
190 load real-time instrument script file (NKSP script language).
191 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
192 - Fixed unintended volume fade-in of voices under certain conditions.
193 - sfz parser: allow missing space between header and opcode
194
195 * Gigasampler/GigaStudio format engine:
196 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
197 cutoff settings.
198 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
199 all if an up-pitch of more than 40 semi tones was requested (I don't
200 think there is any stock gig sound that requires this behavior to
201 resemble its original sound).
202 - Added support for controlling whether the individual EGADSR stages may
203 be aborted (as LinuxSampler extension to the original GigaStudio 4
204 format).
205
206 * general changes:
207 - fixed printf type errors (mostly in debug messages)
208 - use unique_ptr instead of auto_ptr when building with C++11
209 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
210 allowing to sort data efficiently in real-time safe manner.
211 - RTList class: added methods for moving/inserting elements to arbitrary
212 position within a list.
213 - RTList class: added method fromPtr() for creating an Iterator object from
214 a raw element pointer.
215 - Attempt to partly fix resetting engine channels vs. resetting engine, an
216 overall cleanup of the Reset*(), ConnectAudioDevice(),
217 DisconnectAudioDevice() API methods would still be desirable though,
218 because the current situation is still inconsistent and error prone.
219 - Active voices are now internally grouped to "Note" objects, instead of
220 being directly assigned to a keyboard key. This allows more fine graded
221 processing of voices, which is i.e. required for certain instrument
222 script features.
223 - Fix: Release trigger voices were not spawned on sustain pedal up
224 (CC #64) events.
225 - Fix: Release trigger voices can now also distinguish correctly between
226 note-off and sustain pedal up events.
227 - All engines: Increased ramp speed of volume smoother and pan smoother
228 (while slow rate of crossfade smoother is preserved) to allow quick
229 volume and pan changes by instrument scripts for instance.
230 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
231 properly and thus were ignored for certain uses.
232 - Added new C++ API method
233 VirtualMidiDevice::SendChannelPressureToSampler().
234 - windows, 32-bit: fixed potential crashes by making sure the stack in
235 sub threads is 16-byte aligned
236 - fixed numerous compiler warnings
237 - Fixed invalid (note-on) event ID being assigned to new Note objects.
238 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
239 fixes potential undefined behavior.
240 - Fixed Note object leak when triggering notes on keys which did not
241 have a valid sample mapped (fixes bug #252).
242 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
243 - linuxsampler binary fix: option --create-instruments-db ignored
244 subsequent optional argument due to glibc's implementation oddity
245 which expects a "=" sign, but no space between them.
246
247 * packaging changes:
248 - removed unnecessary dependency to libuuid
249 (originated by libgig's usage of it)
250 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
251 auto detect whether it (sh/c)ould output its messages in color.
252 - Debian: Fixed packaging error about invalid "Source-Version"
253 substitution variable.
254 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
255 - Debian: Added build dependency to libsqlite3-dev for building
256 linuxsampler with instruments DB support.
257
258 * Real-time instrument scripts:
259 - Implemented scheduler for delayed MIDI events and for suspended scripts.
260 - Built-in script function "wait()": implemented support for function's
261 "duration-us" argument, thus scripts using this function are now
262 correctly resumed after the requested amount of microseconds.
263 - Built-in script function "play_note()": implemented support for
264 function's "duration-us" argument, thus notes triggered with this
265 argument are now correctly released after the requested amount of
266 microseconds.
267 - Fix: script events were not cleared when engine channel was reset,
268 potentially causing undefined behavior.
269 - Fixed crash which happened when trying to reference an undeclared
270 variable.
271 - Built-in script function "play_note()": Added support for passing
272 special value -1 for "duration-us" argument, which will cause the
273 triggered note to be released once the original note was released.
274 - Instrument script classes now exported with the liblinuxsampler C++ API.
275 - Added new API method ScriptVM::syntaxHighlighting() which provides
276 a convenient syntax highlighting backend for external instrument
277 script editor applications.
278 - Added new C++ API class "ScriptVMFactory".
279 - Extended parser issues to provide not only first line and first
280 column, but also last line and last column of issue (thus marking
281 the precise span of the issue within the source code).
282 - Reload script automatically after being modified by an instrument
283 editor.
284 - NKSP language grammar correction: allow empty event handler bodies
285 like "on note end on".
286 - Implemented built-in script function "change_vol()".
287 - Implemented built-in script function "change_tune()".
288 - Implemented built-in script function "change_pan()".
289 - Implemented built-in script function "change_cutoff()".
290 - Implemented built-in script function "change_reso()".
291 - Implemented built-in script function "event_status()".
292 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
293 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
294 "event_status()" function.
295 - NKSP language: Added support for bitwise operators ".or.", ".and."
296 and ".not.".
297 - NKSP language scanner: Fixed IDs matching to require at least one
298 character (i.e. when matching function names or variable names).
299 - NKSP language scanner: disabled unusued rules.
300 - Fixed behavior of play_note() and note_off() functions which must
301 be distinguished engine internally from "real" MIDI note on/off
302 events in order to avoid misbehaviors like hanging notes.
303 - Implemented built-in script variable "$KSP_TIMER".
304 - Implemented built-in script variable "$NKSP_REAL_TIMER".
305 - Implemented built-in script variable "$NKSP_PERF_TIMER".
306 - Implemented built-in script variable "$ENGINE_UPTIME".
307 - Implemented built-in script function "inc()".
308 - Implemented built-in script function "dec()".
309 - NKSP language fix: division expressions were evaluated too often.
310 - NKSP language fix: string concatenation operator was right
311 associative instead of left (to right).
312 - NKSP language correction: allow empty statements in entire language
313 (i.e. "if end if").
314 - Implemented built-in script function "stop_wait()".
315 - Implemented built-in script variable "$NI_CALLBACK_ID".
316 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
317 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
318 - Added support for read-only built-in variables (respectively
319 handled by the script parser).
320 - Added built-in script constant "$NI_CB_TYPE_INIT".
321 - Added built-in script constant "$NI_CB_TYPE_NOTE".
322 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
323 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
324 - NKSP Language: Added support for user defined script functions.
325 - Implemented built-in script function "change_attack()".
326 - Implemented built-in script function "change_decay()".
327 - Implemented built-in script function "change_release()".
328 - Fixed all change_*() built-in script functions to apply their
329 synthesis parameter changes immediately in case the respective note
330 was triggered at the same time, instead of scheduling the parameter
331 change, especially because it would cause some parameter types's
332 changes either to be ramped (i.e. change_vol()) or other types even
333 to have not effect at all (i.e. change_attack()).
334 - Implemented built-in script function "sh_left()".
335 - Implemented built-in script function "sh_right()".
336 - Implemented built-in script function "min()".
337 - Implemented built-in script function "max()".
338 - NKSP Fix: "init" event handler was not always executed when a script
339 was loaded.
340 - NKSP built-in wait() script function: abort script execution if
341 a negative or zero wait time was passed as argument (since this is
342 a common indication of a bug either of the script or even of the
343 engine, which could lead to RT instability or even worse).
344 - ScriptVM: Implemented automatic suspension of RT safety
345 threatening scripts.
346 - Provide more user friendly error messages on syntax errors.
347 - Fixed NKSP parser warning "Not a statement" when assigning an
348 initializer list to an array variable.
349 - Implemented built-in script array variable "%ALL_EVENTS".
350 - Implemented built-in script function "in_range()".
351 - Implemented built-in script function "change_amp_lfo_depth()".
352 - Implemented built-in script function "change_amp_lfo_freq()".
353 - Implemented built-in script function "change_pitch_lfo_depth()".
354 - Implemented built-in script function "change_pitch_lfo_freq()".
355 - Implemented built-in script function "change_vol_time()".
356 - Implemented built-in script function "change_tune_time()".
357 - Implemented built-in script function "fade_in()".
358 - Implemented built-in script function "fade_out()".
359 - Fixed acceptance of wrong data type of parameters passed to built-in
360 script functions "change_vol()", "change_tune()", "change_pan()",
361 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
362 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
363 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
364 - Added built-in script function "get_event_par()" and implemented some
365 of its possible parameter selections.
366 - Added built-in script function "set_event_par()" and implemented some
367 of its possible parameter selections.
368 - Fixed a bunch of scheduler time related bugs.
369 - Fixed polyphonic variables not being reset to zero after usage.
370 - Built-in "ignore_event()" function: argument is now optional, like with
371 built-in function "ignore_controller()".
372 - Implemented built-in script function "change_velo()".
373 - Implemented built-in script function "change_note()".
374 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
375 intuitive behavior if used in combination with "change_vol_time()" or
376 "change_tune_time()" respectively: now tuning/volume changes are only
377 assigned (without delay) immediately to a new note if the respective
378 timing function has not been called before, otherwise the volume/tuning
379 changes are automatically faded (before, only the event's time stamp was
380 relevant).
381 - Implemented built-in script function "array_equal()".
382 - Implemented built-in script function "search()".
383 - Implemented built-in script function "sort()".
384 - NKSP Fix: Never suspend "init" event handlers.
385 - Implemented built-in script function "same_region()" (currently only
386 available for gig format engine).
387 - Added built-in script constant "$NKSP_LINEAR".
388 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
389 - Implemented built-in script function "change_vol_curve()".
390 - Implemented built-in script function "change_tune_curve()".
391 - built-in "play_note()" function now supports a sample playback start
392 offset with argument 3, where special value -1 means to use the regular
393 sample offset as defined by the instrument file.
394 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
395 - Built-in variable $EVENT_NOTE is now a read-only variable.
396 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
397 - built-in "play_note()" function now accepts -2 for its fourth argument
398 (note duration) which means the life time of the note shall be sticked
399 to the requested note number of argument 1.
400 - Fix: built-in "play_note()" function now returns 0 as result value if
401 -1 was passed for its fourth argument (note duration) and the respective
402 parent note is already gone.
403 - Implemented built-in script function "change_play_pos()".
404 - NKSP language: Added support for user declared const array variables.
405 - NKSP language: Raise parser warning if array variable is accessed with
406 an index that exceeds the array's size.
407 - NKSP language fix: Unknown characters were not handled correctly.
408 - NKSP language: Added support for "synchronized .. end synchronized"
409 code blocks.
410 - Implemented built-in script function "abort()" which allows to abort
411 another script handler by passing its callback ID.
412 - Fixed potential memory access bug and potential undefined behavior of
413 "init" event handlers.
414 - Print a time stamp along to each call of built-in function "message()".
415 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
416 to retrieve all code blocks filtered out by the preprocessor.
417 - Added built-in script function "fork()".
418 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
419 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
420 - Fixed potential crash when accessing dynamic built-in array variables.
421 - Added built-in script function "callback_status()".
422 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
423 - Added built-in constant $CALLBACK_STATUS_QUEUE.
424 - Added built-in constant $CALLBACK_STATUS_RUNNING.
425 - Removed max. value limitation of built-in functions "change_attack()",
426 "change_decay()" and "change_release()" to i.e. allow passing 2000000
427 for doubling the respective time.
428 - NKSP script editor syntax highlighting API: Fixed app termination due
429 to a lexer start condition stack underrun.
430 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
431 USE_CODE_IF_NOT() preprocessor statements.
432 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
433 can be set to disable all subsequent built-in "message()" function calls
434 on preprocessor level.

478 - modernized configure script
479 - fixed linkage error when building with
480 LDFLAGS="-Wl,--no-undefined" (#190)
481 - fixed compilation with Clang 3.2
482 - removed usage of deprecated Automake variable INCLUDES

496
497 * general changes:
498 - Refactoring: moved the independent code from
499 the Gigasampler format engine to base classes
500 - command line option '--profile' is currently disabled, since the
501 respective profiling code is currently broken
502 - Introduced support for optional environment variable
503 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
504 where the sampler shall look for instrument editor plugins
505 (patch by Luis Garrido, slightly modified).
506 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
507 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
508 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
509 note (in this implementation of the sampler its simply hard routed to
510 the 1st effect send of the sampler channel, no matter what the actual
511 effect type is)
512 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
513 note (in this implementation of the sampler its simply hard routed to
514 the 2nd effect send of the sampler channel, no matter what the actual
515 effect type is)
516 - implemented support for internal LADSPA effects
517 - raised limit of program change queue from 100 to 512
518 (as suggested by Alex Stone)
519 - implemented sine LFO, pulse LFO and saw LFO
520 - experimental support for per voice equalization
521 - added command line option --exec-after-init
522 - Introduced new C++ API method:
523 EngineChannel::InstrumentFileName(int index)
524 allowing to retrieve the whole list of files used for the loaded
525 instrument on an engine channel (a.k.a. part). Some GigaStudio
526 instruments for example are splitted over several files like
527 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
528 - Added new C++ API method Sampler::GetGlobalMaxVoices().
529 - Added new C++ API method Sampler::GetGlobalMaxStreams().
530 - Added new C++ API method Sampler::SetGlobalMaxVoices().
531 - Added new C++ API method Sampler::SetGlobalMaxStreams().
532 - Various "const" and "restrict" optimizations.
533 - all engines: add pan CC value to instrument pan parameter before
534 applying panning, instead of using two separate pan functions in
535 series (#182)
536 - added a lock guard class for exception safe mutex handling and
537 used it everywhere appropriate
538 - Immediately apply scale tuning changes to active voices.
539 - Exposed scale tuning to C++ API (along to the already existing standard
540 SysEx way).
541 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
542 and broken for ppc64. (Seq_cst loads and stores are actually not
543 used in LS, so the bug wasn't noticable.)
544 - lsatomic.h: added ARMv7 support
545 - Added support for multiple MIDI input ports per sampler channel (and
546 added various new C++ methods for this new feature / design change, old
547 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
548 as deprecated but are still there and should provide full behavior
549 backward compatibility).
550 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
551 unsafe and caused compilation error with clang 2.x).
552 - Bugfix: only process the latest MIDI program change event.
553 - Introducing the LSCP shell, which provides convenient control of the
554 sampler from the command line by providing LSCP aware features.
555 - VirtualMidiDevice: Added support for program change.
556 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
557 - VirtualMidiDevice: Added support for pitch bend.
558 - Aftertouch: extended API to explicitly handle channel pressure and
559 polyphonic key pressure events (so far polyphonic pressure was not
560 supported at all, and channel pressure was rerouted as CC128 but not
561 used so far).
562 - Added initial support for real-time instrument scripts. The script VM
563 code is shared by all sampler engine implemementations, however only the
564 gig file format currently provides support for storing instrument scripts
565 (as LinuxSampler extension to the original GigaStudio 4 format).
566
567 * Gigasampler format engine:
568 - implemented the "round robin keyboard" dimension
569 - fixed round robin and random dimensions for cases when number of
570 dimension zones is not a power of two

572 key
573 - bugfix: pitch LFO controller "internal+aftertouch" was broken
574 - bugfix: filter keyboard tracking was broken
575 - filter performance fix (an unnecessary copy was made of the
576 filter parameters in each sub fragment)
577 - handle special case when pan parameter in gig file has max or
578 min value
579 - Exclusive Groups: don't ever stop voices of the same note,
580 doesn't sound naturally with a drumkit
581 - fixed EG1 modulation when attack or release is zero
582 - Fixed support for 'aftertouch' attenuation controller.
583 - Fixed crash that happened with velocity split sounds under certain
584 conditions (see also previous commit on libgig).
585 - fixed behaviour of filter LFO
586
587 * SFZ format engine:
588 - Initial implementation (not usable yet)

617 - added support for loop_mode=one_shot
618 - fixed playback of 16 bit wav files on big endian CPUs
619 - added support for Ogg Vorbis sample files
620 - use loop markers from sample file if loop_start and loop_end are
621 not set in sfz file
622 - implemeted filters. Filter types: lowpass, bandpass, bandreject
623 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,

763 - Listen to all interfaces on Mac OS X (INADDR_ANY)
764 - VST bugfix: If the host called resume() before and after
765 changing sample rate or block size, the number of channels was
766 incorrectly set to two. This caused silence in Cubase 5.
767 - save engine type (gig, sfz or sf2) in plugin state
768 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
769 64 bit Windows

812 which allows to retrieve the list of CoreMIDI clients / ports and to connect
813 to them a la JACK, via the usual sampler APIs
814 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
815 the driver will automatically connect to other CoreMIDI clients' ports
816 (e.g. external MIDI devices being attached to the Mac)
817 - added support for MIDI note on velocity filter
818 - CoreMIDI: fixed memory deallocation error
819 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
820 virtual keyboards in frontends / instrument editors being stuck.
821 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
822 - Implemented missing handling of MIDI "running status".
823 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
824 - MME bugfix: driver wasn't closed properly

942 - Pass/preserve polyphonic variable data from respective "note" event
943 handler to "release" event handler.

945
946 * Bug fixes:
947 - Fixed crash which may occur when MIDI key + transpose is out of range
948 - minor valgrind fixes
949 - fixed crash which occurred when changing an already deployed sampler
950 channel to a different engine type
951 - fixed crash when deleting a sampler channel or changing engine
952 type while an instrument load was in progress
953 - bugfix: playing a note while changing the instrument could cause
954 a crash, or give "Handing back unknown region" error messages
955 - bugfix: calling SET VOICES (which Fantasia does on start and
956 refresh) could cause instruments to be unloaded
957 - Mac OS X: fixed name collision of enum in EffectControl and
958 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
959 - Mac OS X: fixed hanging threads
960 - Windows: disabled the previous thread fix on non-Mac systems, as
961 it caused hanging threads on Windows
962 - Fixed possible crashes due to corrupted MIDI/audio device list
963 after MIDI/audio device creation failure
964 - When creating MIDI instrument map entries with "PERSISTENT" type, the
965 instruments were uselessly precached with zero samples, however it still
966 took the full preloading time and on 1st program change the respective
967 instrument was completely reloaded again.
968 - fixed handling of rapid bank select and program change messages
969 sent to the same sampler channel (patch from the Open Octave
970 project, slightly adjusted)
971 - fixed crash when trying to create an effect instance with controls
972 which min and/or max values depend on the sample rate

985 playing a note in a key group
986 - fixed erroneous error message piping in VoiceBase.h
987 (labelled "Disk stream not available in time")
988 - Update effects on sample rate & period size changes (to avoid
989 crashes and noise on such transitions).
990 - ignore missing LADSPA paths without ignoring valid LADSPA paths
991 (fixes #208)
992 - Fixed bug in LSCP grammar definition which caused a statement like
993 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
994 practically irrelevant, however it caused problems with the new LSCP
995 shell's auto completion feature).
996 - Fixed MIDI program change messages being ignored if quickly executed
997 after each other (fixes #231).
998
999 Version 1.0.0 (31 July 2009)
1000
1001 * packaging changes:
1002 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1003 causing e.g. the libgig test to fail when
1004 "./configure --disable-jack-driver" was used
1005 (patch by Alexis Ballier)
1006 - fixed compilation with gcc 4.3
1007 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1008 - fixed configure so it detects x86_64 (#107)
1009 - fixes for building with newer MinGW versions
1010 - fix for building with bison 2.4 (#111)
1011 - fixed building with libgig installed in a non-standard directory
1012 - minor fix in configure for mmsystem.h detection on MinGW
1013 - Windows: look for editor plugins and Fantasia using base
1014 directory of liblinuxsampler dll (look in the same directory and one
1015 directory above)
1016 - configure script fix: removed unconditional use of SSE
1017 - fixed building with sqlite installed in a non-standard directory
1018 - when cross-compiling, don't try to create instruments.db
1019 - fix for new mingw-w64 version, which has usleep
1020
1021 * general changes:
1022 - bugfix: on some POSIX systems instrument editor plugins refused to
1023 load as we used a non-portable Linux specific struct field
1024 (fixes bug #70, patch by Ronald Baljeu)
1025 - fixed endless loop which occured when loading an instrument editor
1026 plugin DLL on Windows systems failed
1027 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1028 - optimized the SynchronizedConfig class so it doesn't wait
1029 unnecessarily long after an update
1030 - added support for notifying instrument editors on note-on / note-off
1031 events (e.g. to highlight the pressed keys on the virtual keyboard
1032 of gigedit)
1033 - added support for triggering notes by instrument editors (see above)
1034 - be verbose on DLL load errors (on Linux)
1035 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1036 is only used by very few systems, most pick the int math
1037 implementation, which is usually faster)
1038 - fixes for audio drivers with varying buffer sizes
1039 - experimental support for running LinuxSampler as a DSSI, LV2 and
1040 VST plugin
1041 - notification events for stream/voice count statistics are now sent
1042 only when there are actual changes
1043 - added memory ordering constraints to improve stability on
1044 multi-core and multi-cpu systems
1045 - maximum voices and disk streams can now be altered at runtime
1046 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1047 - automatic stacktrace mechanism is now turned off by default and can
1048 be switched on by command line option "--stacktrace" (the automatic
1049 stacktrace mechanism seems to be broken on most systems at the moment)
1050 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1051 a pointer to the launched InstrumentEditor object
1052 - added optional 3rd party user data parameter for following
1053 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1054 InstrumentEditor::Launch(),
1055 InstrumentManager::LaunchInstrumentEditor()
1056 - theoretical fix: made SynchronizedConfig follow C++0x memory
1057 model more strictly
1058 - fixes for using large audio device buffers
1059 - Windows: add the installation directory to the DLL search path
1060 when loading an editor plugin (solves problems with VST and
1061 gigedit on systems with other GTK versions installed)
1062 - updated linuxsampler man page
1063
1064 * audio driver:
1065 - removed the nonsense audio channel constraint (which was hard coded to
1066 max. 100 audio channels) for most audio drivers
1067 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1068 opposed to the LSCP specs
1069 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1070 reflected the wrong value
1071 - fixed a memory management bug in ASIO driver
1072 - Makefile fix: JACK_CFLAGS wasn't used
1073 - JACK: use jack_client_open instead of the deprecated
1074 jack_client_new
1075 - added (experimental) CoreAudio driver
1076 - applied old fixes to the ASIO driver that were included in the
1077 previous binary release but accidentally never committed to CVS
1078 (fixes #117)
1079 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1080 win64)
1081 - VST: added support for sample rate and buffer size changes
1082 - VST: close editor (Fantasia) when the VST is removed
1083 - VST: avoid opening Fantasia more than once for each VST instance
1084 - VST: export main function as "main" on Linux too (fix for
1085 energyXT)
1086 - VST: changed number of output channels from one stereo to 16
1087 stereo
1088 - added channel routing, fxsends and midi maps to the settings
1089 stored in the plugin state
1090 - performance optimization of AudioChannel::MixTo() and
1091 AudioChannel::CopyTo() methods using GCC vector exensions
1092 (if available)
1093 - ASIO fixes: avoid initializing the device twice, avoid throwing
1094 exception when getting parameters from a disconnected device
1095
1096 * MIDI driver:
1097 - added JACK MIDI driver
1098 - dispatch bank select as ordinary CC as well, the user might seriously
1099 want to (mis)use it for some purpose ("fixed" in all current MIDI
1100 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1101 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1102 CoreMidi or AU
1103 - fixed mingw-w64 compilation error in MME driver
1104 - made program change handling in MIDI thread real-time safe by
1105 moving the logic to a non-RT thread
1106 - fixed minor memory leak in ALSA driver
1107
1108 * instruments database:
1109 - avoid time consuming samples scanning when adding instruments
1110 to the instruments database
1111 - added support for handling lost files in the instruments database
1112 - Implemented option for adding instruments in separate directories
1113 in the instruments database
1114 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1115 - work-around for missing fnmatch function on Windows to make
1116 instrument database compilable
1117 - added instrument database support on Windows
1118 works with both standalone mode and VST plugin.
1119 the instruments DB file is located in
1120 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1121 databases for each windows user
1122 if no DB is present it automatically creates the .linuxsampler subdir
1123 and then creates an empty DB
1124 - fixed recursive import, which was broken on Windows
1125
1126 * Gigasampler format engine:
1127 - fixed a memory leak that could happen when a channel was deleted
1128 while notes were playing
1129 - made it possible to load an instrument even if the audio thread
1130 isn't running
1131 - added partial support for the "Controller Triggered" MIDI rule,
1132 enough for piano gigs with pedal noise samples
1133 - minor fix: only mark FX sends as being modified if really the
1134 respective FX send MIDI controller was used
1135 - added support for GM global device volume SysEx message
1136 (can be selected at compile time to either apply globally to the
1137 whole sampler [default] or only to the sampler channels that are
1138 connected to the respective MIDI input port the SysEx message arrived
1139 on)
1140 - bugfix: notes triggered at position 0 in the audio buffer were
1141 sometimes wrongly killed in the same buffer, causing no sound to
1142 be played
1143 - added support for chromatic / drumkit mode Roland GS Sysex message
1144 which is usally used to switch a part between chromatic sounds and
1145 drumkit sounds (as opposed to their common default setting of MIDI
1146 part 10 being a drumkit part and all other ones chromatic parts), in
1147 LS however one can switch between the first 16 MIDI instrument maps
1148 defined for the sampler
1149 - made it possible to create multiple sample channels even if the
1150 audio thread isn't running
1151 - fixed crash when removing channel with active voices (#116)
1152 - bugfix: on sample reference changes (instrument editor), only
1153 un-cache the respective sample if it's really not used by any
1154 sampler engine anymore
1155 - re-cache samples in case they were changed by an instrument editor,
1156 e.g. when a sample was added while playing (#82)
1157 - fixed hanging notes which occured when note-off event had the exact
1158 same time stamp as the voice's note-on event and occured both in the
1159 same audio fragment cycle (fixes bug #112)
1160 - added support for the "fine tune" and "pitch bend range"
1161 instrument-level gig parameters
1162 - fixed minor artifacts in pitch bend handling
1163 - added support for GS Reset SysEx message
1164 - allow gig files to use unlimited downward pitch shifting
1165 - added a limit check for upward pitch shifting
1166 - bugfix: sometimes, when playing a note twice fast, the second
1167 note was silent
1168 - fixed crash happening when a pitch bend event arrived at the
1169 same time a new instrument was loading
1170
1171 * LSCP server:
1172 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1173 react on MIDI data arriving on certain sampler channels (so far only
1174 Note-On and Note-Off events are sent via this LSCP event)
1175 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1176 react on MIDI data arriving on certain MIDI input devices (so far only
1177 Note-On and Note-Off events are sent via this LSCP event)
1178 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1179 SET DB_INSTRUMENT FILE_PATH
1180 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1181 frontends to send MIDI messages to specific sampler channel
1182 - added two additional fields to GET FILE INSTRUMENT INFO command -
1183 KEY_BINDINGS and KEYSWITCH_BINDINGS
1184 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1185 was incorrect
1186 - Optimized the retrieval of the MIDI instrument mappings
1187 - added new LSCP command "SET VOICES" to globally alter the maximum
1188 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1189 be triggered respectively
1190 - added new LSCP command "SET STREAMS" to globally alter the maximum
1191 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1192 which will be triggered respectively
1193 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1194 a gigedit file dialog is opened)
1195 - close all connections when LSCPServer is deleted
1196 - hard close of all sockets on exit
1197 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1198 driver
1199
1200 * Bug fixes:
1201 - fixed a crash which occurs when removing a sampler channel waiting
1202 to start instrument loading after another channel
1203 - fixed a crash which occurs when removing a sampler channel with
1204 instrument loading in progress (bug #113)
1205 - fixed termination caused by uncaught exception when adding MIDI
1206 instrument with PERSISTENT load mode
1207 - fixed possible iterator invalidations when resetting the sampler
1208 - fixed memory leaks when issuing the following LSCP commands:
1209 GET AUDIO_OUTPUT_DRIVER INFO
1210 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1211 GET MIDI_INPUT_DRIVER INFO
1212 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1213 - fixed possible compilation error when sqlite is not present
1214 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1215 - fixed crash when changing the audio output device of a sampler
1216 channel with loaded instrument and start playing notes
1217 - fixed endless loop in Engine::SuspendAll() (bug #120)
1218 - fixed a low-level atomic load function that was broken on 64-bit
1219 PowerPC, which probably could cause crashes on that platform
1220 - fixed a memory management error which could cause a crash when a
1221 plugin was unloaded
1222 - bugfix: two private structs had the same name, which could cause
1223 problems if the linker chose the wrong constructor
1224 - fixed low-level ConditionServer usage bug that caused lockups on
1225 Windows
1226
1227
1228 Version 0.5.1 (6 December 2007)
1229
1230 * packaging changes:
1231 - added autoconf checks for pthread library
1232 - added autoconf check for pthread bug found on certain NPTL-enabled
1233 glibc versions (see Gentoo bug report #194076)
1234 - added autoconf checks for MS Windows
1235
1236 * general changes:
1237 - bugfix: the thread used by an editor plugin didn't die when the
1238 editor closed
1239 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1240 out all the space. operator--() did not apply size_mask after
1241 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1242 order to avoid problems with the _NonVolatileReader functions.
1243 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1244 GetWriteSpace(). Since this function is currently only used in
1245 the stream's qsort() compare function, it didn't trigger any
1246 bugs.
1247 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1248 24bit mode too. Faster method to read 24bit words on little
1249 endian machines (x86): replaced 3 byte reads + shifts with a 1
1250 unaligned 32bit read and shift
1251 - experimental support for MS Windows (MIDI input via MME, AUDIO
1252 output via ASIO)
1253 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1254 - support for monitoring the total number of active disk streams
1255 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1256 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1257
1258 * AUDIO driver:
1259 - added Windows ASIO low latency audio driver
1260
1261 * MIDI driver:
1262 - added MME Windows MIDI driver
1263
1264 * LSCP server:
1265 - added support for Windows style path / filenames, however with
1266 forward slash path separators instead of backslash
1267 (i.e. "C:/foo/bar.gig")
1268 - allow naughty liblscp to send non-string device parameters within
1269 apostrophes as well
1270 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1271 "LIST FILE INSTRUMENTS <file>" and
1272 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1273 about an arbitrary instrument file on the system where the sampler is
1274 running on
1275
1276 Version 0.5.0 (15 October 2007)
1277
1278 * packaging changes:
1279 - config.h is not going to be installed along with liblinuxsampler's
1280 API header files anymore
1281 - only the API relevant header (and source) files will be exported to
1282 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1283 - added completely new XCode project files for Mac OSX which is now
1284 capable to execute our autoconf environment, thus no need anymore
1285 to maintain the compile time configuration file (osx/version.h) for
1286 OSX manually (patch by Toshi Nagata)
1287 - fixed buggy boolean --enable-foo / --disable-foo configure script
1288 parameters
1289 - global.h now only covers global definitions that are needed for the
1290 C++ API header files, all implementation internal global definitions
1291 are now in global_private.h
1292 - atomic.h is not exposed to the C++ API anymore
1293 - no need to include config.h anymore for using LS's API header files
1294 - fixed warnings in API doc generation
1295
1296 * general changes:
1297 - replaced the old, confusing MIDI program change mechanism by a
1298 flexible MIDI instrument mapper which allows to map arbitrary
1299 (MIDI bank, MIDI program) pairs with arbitrary
1300 (engine type, instrument file, file index) triplets which will be
1301 loaded on the respective channel when such MIDI program change
1302 messages arrive, beside that, each entry allows to define a life-time
1303 strategy for the instrument, so the user can define whether the
1304 instrument should i.e. be permanently loaded (to be able to switch
1305 quickly among sounds) or i.e. loaded just on demand when the
1306 respective program change arrives (to safe RAM space), as well as a
1307 global volume factor for each entry, so the user can adjust the volume
1308 dynamic of his mapped instrument collection without having to modify
1309 the instrument files, also one can manage arbitrary amount of such
1310 MIDI instrument maps and assign each sampler channel individually
1311 a certain map, so that i.e. separation of normal instruments and
1312 drumkits is possible
1313 - new notification events for tracking changes to audio/MIDI devices,
1314 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1315 - sampler was limited to load max. 200 instruments in the background
1316 due to a constant size RingBuffer FIFO which is now replaced by a
1317 dynamic (unlimited) size std::list FIFO
1318 - added FX sends, these allow to route audio signals to arbitrary audio
1319 output channels for being processed by external effect processors
1320 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1321 controllers
1322 - global (sampler wide) volume can now be controlled at runtime
1323 - Implemented new, improved notification system
1324 - fixed compilation errors regarding OSX
1325 (patch by Toshi Nagata)
1326 - implemented instruments database
1327 - added support for escape sequences to the instruments database
1328 - added highly experimental support for on-the-fly instrument editing
1329 within the sampler's process (by using instrument editor plugins),
1330 you'll notice the new "Registered instrument editors:" message on
1331 startup, added a new LSCP command:
1332 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1333 to spawn a matching instrument editor for the instrument on the
1334 given sampler channel, the plugin path can be overridden at compile
1335 time with ./configure --enable-plugin-dir=/some/dir
1336 - added experimental code for synchronizing instrument editors hosted
1337 in the sampler's process to safely edit instruments while playing
1338 without a crash (hopefully) by either suspending single regions
1339 wherever possible or if unavoidable whole engine(s)
1340 - fixed several issues in fundamental "Thread" class: set scheduling
1341 policy and priority on thread level, set a minimum stack size for
1342 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1343 threads simply inherited properties of starting thread instead of
1344 setting their own policy and priority
1345 - minor fix in our automatic stack trace mechanism on crashes, the
1346 main process did not wait for the stack trace process to finish
1347 its output
1348 - fixed some minor memory leaks
1349 - reenabled assembly features support, at the moment only for
1350 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1351 - minor assembly fix in x86 features detection (don't use the PIC
1352 register, to avoid relocations in the text segment at runtime)
1353 - POSIX callback functions of Thread.h are hidden
1354
1355 * MIDI driver:
1356 - dispatch bank select (MSB and LSB) messages
1357
1358 * audio driver:
1359 - the ALSA audio output driver parameters now reflect the correct
1360 parameter value ranges for the respective selected sound card
1361 (patch by Till Wimmer, a bit fixed and extended)
1362
1363 * Gigasampler format engine:
1364 - if a filter is used and EG2 finishes before EG1, let the voice
1365 die when EG2 has finished (this fixes a problem with clicks and
1366 voice starvation for some gigs)
1367 - playback is no longer disabled during instrument loading
1368 - all notes playing on a channel that changes its instrument keep
1369 playing with the old instrument until they get a note off
1370 command
1371 - EG fix: a release value of zero could cause noises or crash
1372 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1373 - EG fine tuning: when attack is zero the EG starts at a level
1374 above max sustain level, which means that there is a decay phase
1375 even if sustain is 100%
1376 - more EG fixes: the level could sometimes go below zero and cause
1377 noises or crashes
1378 - minor fix of EGDecay (patch by Toshi Nagata)
1379 - fixed compiler error when --enable-override-filter-type was
1380 supplied to the configure script (fixes #46)
1381 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1382 instead of a fix value
1383 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1384 127 (solo mode) only kill voices if the respective mode really
1385 changed
1386
1387 * LSCP server:
1388 - fixed compile time error for old Bison versions
1389 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1390 - parser now supports extended ASCII character set
1391 (up to ASCII code 255, i.e. includes now umlauts and accents)
1392 - filename arguments in LSCP commands now allow to use escape
1393 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1394 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1395 code value like \xf2) (fixes bug #24)
1396 - the following LSCP commands now also support escape sequences for at
1397 least one of their text-based parameters (i.e. name, description):
1398 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1399 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1400 "SET DB_INSTRUMENT_DIRECTORY NAME",
1401 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1402 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1403 "FIND DB_INSTRUMENT_DIRECTORIES"
1404 - returns verbose syntax errors (line and column where syntax error
1405 occured, the unexpected character and the actually expected, possible
1406 character(s), the latter only if less than 5 possibilities)
1407 - made sure that LSCP syntax is not affected by gigedit locale
1408 settings
1409 - bugfix regarding strings parameter lists: all comma separated lists
1410 of strings were treated as being one string containing commas
1411 (fixes #57)
1412
1413 * Bug fixes:
1414 - fixed crash occurring on certain LSCP scripts (Bug 39)
1415 - another thread safety fix for lscp "load engine" and "set
1416 channel audio output device"
1417 - fixed a crash which occurs when reassigning the same engine
1418 on a sampler channel with connected MIDI device
1419 - fixed a crash which occurs when changing the number of ports of a MIDI
1420 device connected to a sampler channel to number less then or equal
1421 to the index of the port to which the sampler channel is connected.
1422 - The previous bindings were not been disconnected when altering
1423 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1424 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1425 - The active stream/voice count statistic was incorrect.
1426 - notification events were not been sent for some sampler
1427 channel changes
1428 - added default min and max values to restrict the number of allowed
1429 audio output channels and MIDI input ports
1430 - the connection to the PCM interface is now closed when destroying
1431 an audio output device
1432 - files with slash in their path or filename could not be loaded
1433
1434 * test cases:
1435 - updated and fixed (haven't been touched in a while)
1436
1437 Version 0.4.0 (24 November 2006)
1438
1439 * packaging changes:
1440 - changed deprecated copyright attribute to license; added ldconfig
1441 to post-(un)install steps; added devel package for liblinuxsampler;
1442 to linuxsampler.spec (RPM)
1443 - install necessary development header files for allowing 3rd party
1444 applications to link against liblinuxsampler
1445 - liblinuxsampler's API documentation can be generated with 'make docs'
1446 (Doxygen required)
1447 - added benchmark to automatically detect the best triangle LFO
1448 implementation (currently either an integer math solution or a
1449 di-harmonic approximation), automatic detection can be overriden
1450 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1451 configure script argument though (mandatory for cross-compilation)
1452 - do not automatically pick optimized gcc flags if the user already
1453 provided some on his own (as CXXFLAGS)
1454 - added compile time option to disable processing of All-Notes-Off MIDI
1455 messages
1456 - added compile time options to allow disabling the various audio and
1457 MIDI drivers
1458 - fixed automatic GCC CPU switch detection on PPC
1459 (patch by Ebrahim Mayat)
1460
1461 * Gigasampler format engine:
1462 - extensive synthesis optimization
1463 (reimplementation of EGs and LFO(s), removed synthesis parameter
1464 prerendering and the synthesis parameter matrix in general, splitting
1465 each audio fragment into subfragments now where each subfragment uses
1466 constant pitch and filter coefficients. The volume coefficient is
1467 linearly interpolated inside a subfragment, unless
1468 --disable-interpolate-volume is set.)
1469 - fine tuning of the EG modulation parameters
1470 - improved filter cutoff calculation by adding support for the
1471 following gig parameters: Cutoff freq (used when no cutoff
1472 controller is defined), Control invert, Minimum cutoff, Velocity
1473 curve and Velocity range. The keyboard tracking now scales
1474 cutoff frequency instead of resonance.
1475 - added support for gig parameter Resonance.
1476 - fixed bug in sysex handling (patch by Juan Linietsky)
1477 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1478 which can be overridden with --enable-global-attenuation
1479 - EG fixes: made the length of "attack hold" stage more
1480 accurate. Release stage can now start before attack stage
1481 ends. Cancel release didn't work when sustain was zero. Attack
1482 time now has a minimal value to prevent clicks.
1483 - fixed pitch changes larger than one octave
1484 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1485 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1486 all modes can be altered via standard GM messages, that is CC5 for
1487 altering portamento time, CC65 for enabling / disabling portamento
1488 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1489 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1490 parameter) and crossfade
1491 - added support for the "attenuation controller threshold" gig
1492 parameter
1493 - added smoothing of volume changes caused by control change
1494 messages
1495 - sample loop parameters are now taken from the DimensionRegion
1496 instead of the wave chunk
1497 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1498 not equal to a power of two
1499 - reimplementation of the filter algorithm. The new filter is more
1500 accurate and supports all gig filter types, including bandreject
1501 and lowpass turbo.
1502 - real support for 24 bit samples - samples are not truncated to
1503 16 bits anymore
1504 - support for aftertouch (channel pressure, not polyphonic
1505 aftertouch)
1506 - LFO1 behaviour fixed (dampening from max volume instead of
1507 amplifying from 0)
1508
1509 * LSCP server:
1510 - fixed application exit on broken pipe error (fixes bug #20)
1511 - fixed the notification messages delay due to lack of
1512 network activity (fixes bug #26)
1513 - fixed parser bug which occured on space(s) within device parameters
1514 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1515
1516 * audio driver:
1517 - added aRts audio output driver (by no means RT safe)
1518
1519 * MIDI driver:
1520 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1521 messages several times instead of once
1522 - API extension for MIDI drivers which already supply exact time stamps
1523 for events (i.e. for offline rendering based MIDI drivers)
1524 - added checks for bad MIDI data
1525
1526 * linuxsampler application:
1527 - show available sampler engine types on startup
1528
1529 * general changes:
1530 - support for muting sampler channels and solo mode of the same, two new
1531 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1532 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1533 introduced for this, the behavior is the same like on a mixer console
1534 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1535 --enable-process-muted-channels which can be used to enable the
1536 processing of muted channels.
1537 - support for sostenuto pedal
1538 - support for monitoring the total number of active voices
1539 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1540 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1541 - fixed some memory management errors
1542 - fixed some concurrency problems that could lead to crashes when
1543 LSCP commands were executed
1544 - fixed crash when instrument loading failed previously on the same
1545 sampler channel (fixes bug #36)
1546
1547 Version 0.3.3 (15 July 2005)
1548
1549 * packaging changes:
1550 - fixed compilation with gcc 4.0
1551
1552 * Gigasampler format engine:
1553 - LFO preprocessing was performed even though the respective LFO was
1554 disabled by the instrument patch (minor efficiency fix)
1555 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1556 for volume ramp downs in the same fragment (needed for current voice
1557 stealing implementation) then simply inform the user with a warning
1558 about possible click sounds and reduce the volume ramp down
1559 appropriately instead of cancelling the audio device connection
1560
1561 Version 0.3.2 (24 June 2005)
1562
1563 * packaging changes:
1564 - updated autotools build files to compile on OS X
1565 (conditional compilation of CoreMIDI and MidiShare drivers)
1566 - hand-crafted assembly optimization code can be disabled with
1567 './configure --disable-asm' (definitely not recommended)
1568 - fixed 'make dist' rule to include all necessary files
1569 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1570 (due to 'dist-bzip2' automake option)
1571
1572 * Gigasampler format engine:
1573 - support for the gig parameters for "release velocity response" curves
1574 - fine tuning of the EGADSR envelope
1575 - volume of release triggered samples now depends on note-on velocity,
1576 note length and gig parameter "release trigger decay" instead of
1577 note-off velocity.
1578 - revised voice stealing
1579 (fixes crash and endless loop caused by voice stealing)
1580 - don't reset scale tuning on instrument or audio output device change
1581 - handle key group conflicts right at the beginning of each fragment
1582 instead of when the respective voice is actually launched
1583 (fixes undefined behavior if stolen voices belonged to a key group -
1584 this case was followed by a "killed voice survived" error message)
1585 - fixed minor issue with null/silence samples
1586 (those stole voices even though they don't need a voice at all which
1587 resulted in "voice stealing didn't work out" messages)
1588 - don't reset volume, pan, pitch and MIDI controller values on
1589 instrument or audio output device change
1590
1591 * LSCP server:
1592 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1593 - fixed LSCP event "CHANNEL_INFO" notification
1594 (e.g. did not notify on volume changes or MIDI program change events)
1595
1596 * linuxsampler application:
1597 - added command line parameters --lscp-addr and --lscp-port to override
1598 default IP address and port of LSCP server
1599
1600 Version 0.3.1 (24 May 2005)
1601
1602 * initial release
