NKSP: Real number support for core instrument built-in functions.

* NKSP: Built-in function "play_note()" accepts now real numbers and
  seconds as unit type as well for its 3rd and 4th function arguments.

* NKSP: The following built-in functions accept now real numbers as well for
  their 2nd function argument: "change_vol()", "change_tune()",
  "change_cutoff()", "change_attack()", "change_decay()",
  "change_release()", "change_sustain()", "change_cutoff_attack()",
  "change_cutoff_decay()", "change_cutoff_sustain()",
  "change_cutoff_release()", "change_amp_lfo_freq()",
  "change_cutoff_lfo_freq()", "change_pitch_lfo_freq()",
  "change_vol_time()", "change_tune_time()", "change_pan_time()",
  "fade_in()", "fade_out()", "change_play_pos()".

* NKSP: Fixed built-in function "change_play_pos()" not having accepted
  metric prefixes at all.

* Bumped version (2.1.1.svn12).

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 - NKSP VM API cleanup: Get rid of legacy method
136 VMFunction::argType(vmint iArg) which was already superseded by its new
137 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
138 - NKSP parser: if wrong argument type was passed to a built-in function and
139 that built-in function accepts more than one data type for the argument,
140 then show all supported data types as parser error message.
141 - Built-in function "play_note()" accepts now real numbers and seconds as
142 unit type as well for its 3rd and 4th function arguments.
143 - The following built-in functions accept now real numbers as well for their
144 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
145 "change_attack()", "change_decay()", "change_release()",
146 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
147 "change_cutoff_sustain()", "change_cutoff_release()",
148 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
149 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
150 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
151 - Fixed built-in function "change_play_pos()" not having accepted metric
152 prefixes at all.
153
154 * test cases:
155 - Fixed compiler errors in test cases.
156 - Updated README for how to compile & run test cases.
157 - Updated test case
158 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
159 expected behaviour of the Mutex class implementation (recursive
160 mutex type).
161 - Added test cases for NKSP core language aspects and core built-in
162 functions.
163 - Fixed thread tests segfaulting on Linux.
164 - NKSP: Added real number test cases for built-in functions exit(),
165 int_to_real(), real(), real_to_int() and int(), as well as for the
166 plus, minus and negate language operators.
167 - Added massive amount of NKSP test cases for standard measuring units and
168 'final' operator usage cases.
169 - Added NKSP test cases for (floating point tolerance aware) real number
170 equalness / unequalness comparison.
171 - Added NKSP int array and real array tests for value assignment and
172 initialization of arrays.
173
174 Version 2.1.1 (27 Jul 2019)
175
176 * Real-time instrument scripts:
177 - Fixed behavior of built-in NKSP functions change_sustain(),
178 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
179 and change_cutoff_release().
180
181 * general changes:
182 - Only play release trigger samples on sustain pedal up if this behaviour
183 was explicitly requested by the instrument (otherwise only on note-off).
184 - Fixed compiler warnings.
185 - Fixed compilation error when cross-compiling to Mac.
186 - FX Sends: Provide more useful error messages on routing problems
187 (see bug #169).
188 - LSCP doc: Be more clear describing the two distinct approaches
189 of using external vs. internal effects (see bug #169).
190 - "optional" class: Fixed comparison operators.
191
192 * Gigasampler/GigaStudio format engine:
193 - Format extension: If requested by instrument then don't play release
194 trigger sample on note-off events.
195
196 * SFZ format engine:
197 - Fixed memory leak when releasing samples
198 (fixes bug #307, patch by Jacek Roszkowski)
199 - Fixed potential crash when a sample is shared by more than one region
200 (fixes bug #308, patch by Jacek Roszkowski).
201 - Opcode 'sample': Added support for built-in sample '*silence'
202 (fixes bug #310, patch by Jacek Roszkowski).
203
204 Version 2.1.0 (25 Nov 2017)
205
206 * SFZ format engine:
207 - added support for <global>, <master> and #define (patch by Alby M)
208 - Removed code duplication in SFZ file loading code.
209 - Added support for sfz extension opcode 'script' which may be used to
210 load real-time instrument script file (NKSP script language).
211 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
212 - Fixed unintended volume fade-in of voices under certain conditions.
213 - sfz parser: allow missing space between header and opcode
214
215 * Gigasampler/GigaStudio format engine:
216 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
217 cutoff settings.
218 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
219 all if an up-pitch of more than 40 semi tones was requested (I don't
220 think there is any stock gig sound that requires this behavior to
221 resemble its original sound).
222 - Added support for controlling whether the individual EGADSR stages may
223 be aborted (as LinuxSampler extension to the original GigaStudio 4
224 format).
225
226 * general changes:
227 - fixed printf type errors (mostly in debug messages)
228 - use unique_ptr instead of auto_ptr when building with C++11
229 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
230 allowing to sort data efficiently in real-time safe manner.
231 - RTList class: added methods for moving/inserting elements to arbitrary
232 position within a list.
233 - RTList class: added method fromPtr() for creating an Iterator object from
234 a raw element pointer.
235 - Attempt to partly fix resetting engine channels vs. resetting engine, an
236 overall cleanup of the Reset*(), ConnectAudioDevice(),
237 DisconnectAudioDevice() API methods would still be desirable though,
238 because the current situation is still inconsistent and error prone.
239 - Active voices are now internally grouped to "Note" objects, instead of
240 being directly assigned to a keyboard key. This allows more fine graded
241 processing of voices, which is i.e. required for certain instrument
242 script features.
243 - Fix: Release trigger voices were not spawned on sustain pedal up
244 (CC #64) events.
245 - Fix: Release trigger voices can now also distinguish correctly between
246 note-off and sustain pedal up events.
247 - All engines: Increased ramp speed of volume smoother and pan smoother
248 (while slow rate of crossfade smoother is preserved) to allow quick
249 volume and pan changes by instrument scripts for instance.
250 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
251 properly and thus were ignored for certain uses.
252 - Added new C++ API method
253 VirtualMidiDevice::SendChannelPressureToSampler().
254 - windows, 32-bit: fixed potential crashes by making sure the stack in
255 sub threads is 16-byte aligned
256 - fixed numerous compiler warnings
257 - Fixed invalid (note-on) event ID being assigned to new Note objects.
258 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
259 fixes potential undefined behavior.
260 - Fixed Note object leak when triggering notes on keys which did not
261 have a valid sample mapped (fixes bug #252).
262 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
263 - linuxsampler binary fix: option --create-instruments-db ignored
264 subsequent optional argument due to glibc's implementation oddity
265 which expects a "=" sign, but no space between them.
266
267 * packaging changes:
268 - removed unnecessary dependency to libuuid
269 (originated by libgig's usage of it)
270 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
271 auto detect whether it (sh/c)ould output its messages in color.
272 - Debian: Fixed packaging error about invalid "Source-Version"
273 substitution variable.
274 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
275 - Debian: Added build dependency to libsqlite3-dev for building
276 linuxsampler with instruments DB support.
277
278 * Real-time instrument scripts:
279 - Implemented scheduler for delayed MIDI events and for suspended scripts.
280 - Built-in script function "wait()": implemented support for function's
281 "duration-us" argument, thus scripts using this function are now
282 correctly resumed after the requested amount of microseconds.
283 - Built-in script function "play_note()": implemented support for
284 function's "duration-us" argument, thus notes triggered with this
285 argument are now correctly released after the requested amount of
286 microseconds.
287 - Fix: script events were not cleared when engine channel was reset,
288 potentially causing undefined behavior.
289 - Fixed crash which happened when trying to reference an undeclared
290 variable.
291 - Built-in script function "play_note()": Added support for passing
292 special value -1 for "duration-us" argument, which will cause the
293 triggered note to be released once the original note was released.
294 - Instrument script classes now exported with the liblinuxsampler C++ API.
295 - Added new API method ScriptVM::syntaxHighlighting() which provides
296 a convenient syntax highlighting backend for external instrument
297 script editor applications.
298 - Added new C++ API class "ScriptVMFactory".
299 - Extended parser issues to provide not only first line and first
300 column, but also last line and last column of issue (thus marking
301 the precise span of the issue within the source code).
302 - Reload script automatically after being modified by an instrument
303 editor.
304 - NKSP language grammar correction: allow empty event handler bodies
305 like "on note end on".
306 - Implemented built-in script function "change_vol()".
307 - Implemented built-in script function "change_tune()".
308 - Implemented built-in script function "change_pan()".
309 - Implemented built-in script function "change_cutoff()".
310 - Implemented built-in script function "change_reso()".
311 - Implemented built-in script function "event_status()".
312 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
313 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
314 "event_status()" function.
315 - NKSP language: Added support for bitwise operators ".or.", ".and."
316 and ".not.".
317 - NKSP language scanner: Fixed IDs matching to require at least one
318 character (i.e. when matching function names or variable names).
319 - NKSP language scanner: disabled unusued rules.
320 - Fixed behavior of play_note() and note_off() functions which must
321 be distinguished engine internally from "real" MIDI note on/off
322 events in order to avoid misbehaviors like hanging notes.
323 - Implemented built-in script variable "$KSP_TIMER".
324 - Implemented built-in script variable "$NKSP_REAL_TIMER".
325 - Implemented built-in script variable "$NKSP_PERF_TIMER".
326 - Implemented built-in script variable "$ENGINE_UPTIME".
327 - Implemented built-in script function "inc()".
328 - Implemented built-in script function "dec()".
329 - NKSP language fix: division expressions were evaluated too often.
330 - NKSP language fix: string concatenation operator was right
331 associative instead of left (to right).
332 - NKSP language correction: allow empty statements in entire language
333 (i.e. "if end if").
334 - Implemented built-in script function "stop_wait()".
335 - Implemented built-in script variable "$NI_CALLBACK_ID".
336 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
337 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
338 - Added support for read-only built-in variables (respectively
339 handled by the script parser).
340 - Added built-in script constant "$NI_CB_TYPE_INIT".
341 - Added built-in script constant "$NI_CB_TYPE_NOTE".
342 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
343 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
344 - NKSP Language: Added support for user defined script functions.
345 - Implemented built-in script function "change_attack()".
346 - Implemented built-in script function "change_decay()".
347 - Implemented built-in script function "change_release()".
348 - Fixed all change_*() built-in script functions to apply their
349 synthesis parameter changes immediately in case the respective note
350 was triggered at the same time, instead of scheduling the parameter
351 change, especially because it would cause some parameter types's
352 changes either to be ramped (i.e. change_vol()) or other types even
353 to have not effect at all (i.e. change_attack()).
354 - Implemented built-in script function "sh_left()".
355 - Implemented built-in script function "sh_right()".
356 - Implemented built-in script function "min()".
357 - Implemented built-in script function "max()".
358 - NKSP Fix: "init" event handler was not always executed when a script
359 was loaded.
360 - NKSP built-in wait() script function: abort script execution if
361 a negative or zero wait time was passed as argument (since this is
362 a common indication of a bug either of the script or even of the
363 engine, which could lead to RT instability or even worse).
364 - ScriptVM: Implemented automatic suspension of RT safety
365 threatening scripts.
366 - Provide more user friendly error messages on syntax errors.
367 - Fixed NKSP parser warning "Not a statement" when assigning an
368 initializer list to an array variable.
369 - Implemented built-in script array variable "%ALL_EVENTS".
370 - Implemented built-in script function "in_range()".
371 - Implemented built-in script function "change_amp_lfo_depth()".
372 - Implemented built-in script function "change_amp_lfo_freq()".
373 - Implemented built-in script function "change_pitch_lfo_depth()".
374 - Implemented built-in script function "change_pitch_lfo_freq()".
375 - Implemented built-in script function "change_vol_time()".
376 - Implemented built-in script function "change_tune_time()".
377 - Implemented built-in script function "fade_in()".
378 - Implemented built-in script function "fade_out()".
379 - Fixed acceptance of wrong data type of parameters passed to built-in
380 script functions "change_vol()", "change_tune()", "change_pan()",
381 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
382 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
383 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
384 - Added built-in script function "get_event_par()" and implemented some
385 of its possible parameter selections.
386 - Added built-in script function "set_event_par()" and implemented some
387 of its possible parameter selections.
388 - Fixed a bunch of scheduler time related bugs.
389 - Fixed polyphonic variables not being reset to zero after usage.
390 - Built-in "ignore_event()" function: argument is now optional, like with
391 built-in function "ignore_controller()".
392 - Implemented built-in script function "change_velo()".
393 - Implemented built-in script function "change_note()".
394 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
395 intuitive behavior if used in combination with "change_vol_time()" or
396 "change_tune_time()" respectively: now tuning/volume changes are only
397 assigned (without delay) immediately to a new note if the respective
398 timing function has not been called before, otherwise the volume/tuning
399 changes are automatically faded (before, only the event's time stamp was
400 relevant).
401 - Implemented built-in script function "array_equal()".
402 - Implemented built-in script function "search()".
403 - Implemented built-in script function "sort()".
404 - NKSP Fix: Never suspend "init" event handlers.
405 - Implemented built-in script function "same_region()" (currently only
406 available for gig format engine).
407 - Added built-in script constant "$NKSP_LINEAR".
408 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
409 - Implemented built-in script function "change_vol_curve()".
410 - Implemented built-in script function "change_tune_curve()".
411 - built-in "play_note()" function now supports a sample playback start
412 offset with argument 3, where special value -1 means to use the regular
413 sample offset as defined by the instrument file.
414 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
415 - Built-in variable $EVENT_NOTE is now a read-only variable.
416 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
417 - built-in "play_note()" function now accepts -2 for its fourth argument
418 (note duration) which means the life time of the note shall be sticked
419 to the requested note number of argument 1.
420 - Fix: built-in "play_note()" function now returns 0 as result value if
421 -1 was passed for its fourth argument (note duration) and the respective
422 parent note is already gone.

494 - fixed compilation with gcc 4.7
495 - fixed configure script error with old autoconf versions

498 - modernized configure script
499 - fixed linkage error when building with
500 LDFLAGS="-Wl,--no-undefined" (#190)
501 - fixed compilation with Clang 3.2
502 - removed usage of deprecated Automake variable INCLUDES

516
517 * general changes:
518 - Refactoring: moved the independent code from
519 the Gigasampler format engine to base classes
520 - command line option '--profile' is currently disabled, since the
521 respective profiling code is currently broken
522 - Introduced support for optional environment variable
523 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
524 where the sampler shall look for instrument editor plugins
525 (patch by Luis Garrido, slightly modified).
526 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
527 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
528 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
529 note (in this implementation of the sampler its simply hard routed to
530 the 1st effect send of the sampler channel, no matter what the actual
531 effect type is)
532 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
533 note (in this implementation of the sampler its simply hard routed to
534 the 2nd effect send of the sampler channel, no matter what the actual
535 effect type is)
536 - implemented support for internal LADSPA effects
537 - raised limit of program change queue from 100 to 512
538 (as suggested by Alex Stone)
539 - implemented sine LFO, pulse LFO and saw LFO
540 - experimental support for per voice equalization
541 - added command line option --exec-after-init
542 - Introduced new C++ API method:
543 EngineChannel::InstrumentFileName(int index)
544 allowing to retrieve the whole list of files used for the loaded
545 instrument on an engine channel (a.k.a. part). Some GigaStudio
546 instruments for example are splitted over several files like
547 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
548 - Added new C++ API method Sampler::GetGlobalMaxVoices().
549 - Added new C++ API method Sampler::GetGlobalMaxStreams().
550 - Added new C++ API method Sampler::SetGlobalMaxVoices().
551 - Added new C++ API method Sampler::SetGlobalMaxStreams().
552 - Various "const" and "restrict" optimizations.
553 - all engines: add pan CC value to instrument pan parameter before
554 applying panning, instead of using two separate pan functions in
555 series (#182)
556 - added a lock guard class for exception safe mutex handling and
557 used it everywhere appropriate
558 - Immediately apply scale tuning changes to active voices.
559 - Exposed scale tuning to C++ API (along to the already existing standard
560 SysEx way).
561 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
562 and broken for ppc64. (Seq_cst loads and stores are actually not
563 used in LS, so the bug wasn't noticable.)
564 - lsatomic.h: added ARMv7 support
565 - Added support for multiple MIDI input ports per sampler channel (and
566 added various new C++ methods for this new feature / design change, old
567 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
568 as deprecated but are still there and should provide full behavior
569 backward compatibility).
570 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
571 unsafe and caused compilation error with clang 2.x).
572 - Bugfix: only process the latest MIDI program change event.
573 - Introducing the LSCP shell, which provides convenient control of the
574 sampler from the command line by providing LSCP aware features.
575 - VirtualMidiDevice: Added support for program change.
576 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
577 - VirtualMidiDevice: Added support for pitch bend.
578 - Aftertouch: extended API to explicitly handle channel pressure and
579 polyphonic key pressure events (so far polyphonic pressure was not
580 supported at all, and channel pressure was rerouted as CC128 but not
581 used so far).
582 - Added initial support for real-time instrument scripts. The script VM
583 code is shared by all sampler engine implemementations, however only the
584 gig file format currently provides support for storing instrument scripts
585 (as LinuxSampler extension to the original GigaStudio 4 format).
586

592 key
593 - bugfix: pitch LFO controller "internal+aftertouch" was broken
594 - bugfix: filter keyboard tracking was broken
595 - filter performance fix (an unnecessary copy was made of the
596 filter parameters in each sub fragment)
597 - handle special case when pan parameter in gig file has max or
598 min value
599 - Exclusive Groups: don't ever stop voices of the same note,
600 doesn't sound naturally with a drumkit
601 - fixed EG1 modulation when attack or release is zero
602 - Fixed support for 'aftertouch' attenuation controller.
603 - Fixed crash that happened with velocity split sounds under certain
604 conditions (see also previous commit on libgig).
605 - fixed behaviour of filter LFO
606
607 * SFZ format engine:

637 - added support for loop_mode=one_shot
638 - fixed playback of 16 bit wav files on big endian CPUs
639 - added support for Ogg Vorbis sample files
640 - use loop markers from sample file if loop_start and loop_end are
641 not set in sfz file

769 - bugfix: line numbers in error messages were wrong after "#include"
770 - added support for float and 32 bit sample files
771
772 * SoundFont format engine:
773 - Initial implementation (not usable yet)
774 - RT-safeness: avoid malloc in audio thread

782 - AU bugfix: failed to destroy its audio/MIDI devices
783 - Listen to all interfaces on Mac OS X (INADDR_ANY)
784 - VST bugfix: If the host called resume() before and after
785 changing sample rate or block size, the number of channels was
786 incorrectly set to two. This caused silence in Cubase 5.
787 - save engine type (gig, sfz or sf2) in plugin state
788 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
789 64 bit Windows
790 - AU: changed number of output channels from one stereo to 16
791 stereo
792 - VST: made it possible to build the VST plugin for Mac

799 loaded a second time (this time it's for Linux and Mac, previous
800 similar fix was for Windows)
801 - thread safety fixes for the instrument loading thread
802 - LV2: use the new lv2 package if present

809 and event
810 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

817
818 * Instrument editor interface:
819 - Changed instrument editor plugin interface, providing additional
820 informations like the EngineChannel for which the instrument editor was
821 spawned for. This allows the instrument editors to interact more actively
822 with the sampler.
823
824 * MIDI driver:
825 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
826 the ALSA sequencer client name

828 there is no reason for this limit
829 - MME: fixed memory handling bug found with cppcheck
830 - MME: removed compiler warning
831 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
832 which allows to retrieve the list of CoreMIDI clients / ports and to connect

970 channel to a different engine type
971 - fixed crash when deleting a sampler channel or changing engine
972 type while an instrument load was in progress
973 - bugfix: playing a note while changing the instrument could cause
974 a crash, or give "Handing back unknown region" error messages
975 - bugfix: calling SET VOICES (which Fantasia does on start and
976 refresh) could cause instruments to be unloaded
977 - Mac OS X: fixed name collision of enum in EffectControl and
978 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
979 - Mac OS X: fixed hanging threads
980 - Windows: disabled the previous thread fix on non-Mac systems, as
981 it caused hanging threads on Windows
982 - Fixed possible crashes due to corrupted MIDI/audio device list
983 after MIDI/audio device creation failure
984 - When creating MIDI instrument map entries with "PERSISTENT" type, the
985 instruments were uselessly precached with zero samples, however it still
986 took the full preloading time and on 1st program change the respective
987 instrument was completely reloaded again.
988 - fixed handling of rapid bank select and program change messages
989 sent to the same sampler channel (patch from the Open Octave
990 project, slightly adjusted)

1009 crashes and noise on such transitions).
1010 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1011 (fixes #208)
1012 - Fixed bug in LSCP grammar definition which caused a statement like
1013 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1014 practically irrelevant, however it caused problems with the new LSCP
1015 shell's auto completion feature).
1016 - Fixed MIDI program change messages being ignored if quickly executed
1017 after each other (fixes #231).
1018
1019 Version 1.0.0 (31 July 2009)
1020
1021 * packaging changes:
1022 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1035 directory above)
1036 - configure script fix: removed unconditional use of SSE
1037 - fixed building with sqlite installed in a non-standard directory
1038 - when cross-compiling, don't try to create instruments.db

1040
1041 * general changes:
1042 - bugfix: on some POSIX systems instrument editor plugins refused to
1043 load as we used a non-portable Linux specific struct field
1044 (fixes bug #70, patch by Ronald Baljeu)
1045 - fixed endless loop which occured when loading an instrument editor
1046 plugin DLL on Windows systems failed
1047 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1048 - optimized the SynchronizedConfig class so it doesn't wait
1049 unnecessarily long after an update
1050 - added support for notifying instrument editors on note-on / note-off
1051 events (e.g. to highlight the pressed keys on the virtual keyboard
1052 of gigedit)
1053 - added support for triggering notes by instrument editors (see above)
1054 - be verbose on DLL load errors (on Linux)
1055 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1056 is only used by very few systems, most pick the int math
1057 implementation, which is usually faster)
1058 - fixes for audio drivers with varying buffer sizes
1059 - experimental support for running LinuxSampler as a DSSI, LV2 and
1060 VST plugin
1061 - notification events for stream/voice count statistics are now sent
1062 only when there are actual changes

1064 multi-core and multi-cpu systems
1065 - maximum voices and disk streams can now be altered at runtime
1066 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1067 - automatic stacktrace mechanism is now turned off by default and can
1068 be switched on by command line option "--stacktrace" (the automatic
1069 stacktrace mechanism seems to be broken on most systems at the moment)
1070 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1071 a pointer to the launched InstrumentEditor object
1072 - added optional 3rd party user data parameter for following
1073 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1074 InstrumentEditor::Launch(),
1075 InstrumentManager::LaunchInstrumentEditor()
1076 - theoretical fix: made SynchronizedConfig follow C++0x memory
1077 model more strictly
1078 - fixes for using large audio device buffers
1079 - Windows: add the installation directory to the DLL search path
1080 when loading an editor plugin (solves problems with VST and
1081 gigedit on systems with other GTK versions installed)
1082 - updated linuxsampler man page
1083
1084 * audio driver:
1085 - removed the nonsense audio channel constraint (which was hard coded to
1086 max. 100 audio channels) for most audio drivers
1087 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1088 opposed to the LSCP specs
1089 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1090 reflected the wrong value
1091 - fixed a memory management bug in ASIO driver
1092 - Makefile fix: JACK_CFLAGS wasn't used
1093 - JACK: use jack_client_open instead of the deprecated
1094 jack_client_new
1095 - added (experimental) CoreAudio driver
1096 - applied old fixes to the ASIO driver that were included in the
1097 previous binary release but accidentally never committed to CVS
1098 (fixes #117)
1099 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1100 win64)
1101 - VST: added support for sample rate and buffer size changes
1102 - VST: close editor (Fantasia) when the VST is removed
1103 - VST: avoid opening Fantasia more than once for each VST instance
1104 - VST: export main function as "main" on Linux too (fix for
1105 energyXT)
1106 - VST: changed number of output channels from one stereo to 16
1107 stereo
1108 - added channel routing, fxsends and midi maps to the settings
1109 stored in the plugin state
1110 - performance optimization of AudioChannel::MixTo() and
1111 AudioChannel::CopyTo() methods using GCC vector exensions
1112 (if available)
1113 - ASIO fixes: avoid initializing the device twice, avoid throwing
1114 exception when getting parameters from a disconnected device
1115
1116 * MIDI driver:
1117 - added JACK MIDI driver
1118 - dispatch bank select as ordinary CC as well, the user might seriously
1119 want to (mis)use it for some purpose ("fixed" in all current MIDI
1120 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1121 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1122 CoreMidi or AU
1123 - fixed mingw-w64 compilation error in MME driver
1124 - made program change handling in MIDI thread real-time safe by
1125 moving the logic to a non-RT thread
1126 - fixed minor memory leak in ALSA driver
1127
1128 * instruments database:
1129 - avoid time consuming samples scanning when adding instruments
1130 to the instruments database
1131 - added support for handling lost files in the instruments database
1132 - Implemented option for adding instruments in separate directories
1133 in the instruments database
1134 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1135 - work-around for missing fnmatch function on Windows to make
1136 instrument database compilable
1137 - added instrument database support on Windows
1138 works with both standalone mode and VST plugin.
1139 the instruments DB file is located in
1140 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1141 databases for each windows user
1142 if no DB is present it automatically creates the .linuxsampler subdir
1143 and then creates an empty DB
1144 - fixed recursive import, which was broken on Windows
1145
1146 * Gigasampler format engine:
1147 - fixed a memory leak that could happen when a channel was deleted
1148 while notes were playing
1149 - made it possible to load an instrument even if the audio thread
1150 isn't running
1151 - added partial support for the "Controller Triggered" MIDI rule,
1152 enough for piano gigs with pedal noise samples
1153 - minor fix: only mark FX sends as being modified if really the
1154 respective FX send MIDI controller was used
1155 - added support for GM global device volume SysEx message
1156 (can be selected at compile time to either apply globally to the
1157 whole sampler [default] or only to the sampler channels that are
1158 connected to the respective MIDI input port the SysEx message arrived
1159 on)
1160 - bugfix: notes triggered at position 0 in the audio buffer were
1161 sometimes wrongly killed in the same buffer, causing no sound to
1162 be played
1163 - added support for chromatic / drumkit mode Roland GS Sysex message
1164 which is usally used to switch a part between chromatic sounds and
1165 drumkit sounds (as opposed to their common default setting of MIDI
1166 part 10 being a drumkit part and all other ones chromatic parts), in
1167 LS however one can switch between the first 16 MIDI instrument maps
1168 defined for the sampler
1169 - made it possible to create multiple sample channels even if the
1170 audio thread isn't running
1171 - fixed crash when removing channel with active voices (#116)
1172 - bugfix: on sample reference changes (instrument editor), only
1173 un-cache the respective sample if it's really not used by any
1174 sampler engine anymore
1175 - re-cache samples in case they were changed by an instrument editor,
1176 e.g. when a sample was added while playing (#82)
1177 - fixed hanging notes which occured when note-off event had the exact
1178 same time stamp as the voice's note-on event and occured both in the
1179 same audio fragment cycle (fixes bug #112)
1180 - added support for the "fine tune" and "pitch bend range"
1181 instrument-level gig parameters
1182 - fixed minor artifacts in pitch bend handling
1183 - added support for GS Reset SysEx message
1184 - allow gig files to use unlimited downward pitch shifting
1185 - added a limit check for upward pitch shifting
1186 - bugfix: sometimes, when playing a note twice fast, the second
1187 note was silent
1188 - fixed crash happening when a pitch bend event arrived at the
1189 same time a new instrument was loading
1190
1191 * LSCP server:
1192 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1193 react on MIDI data arriving on certain sampler channels (so far only
1194 Note-On and Note-Off events are sent via this LSCP event)
1195 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1196 react on MIDI data arriving on certain MIDI input devices (so far only
1197 Note-On and Note-Off events are sent via this LSCP event)
1198 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1199 SET DB_INSTRUMENT FILE_PATH
1200 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1201 frontends to send MIDI messages to specific sampler channel
1202 - added two additional fields to GET FILE INSTRUMENT INFO command -
1203 KEY_BINDINGS and KEYSWITCH_BINDINGS
1204 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1205 was incorrect
1206 - Optimized the retrieval of the MIDI instrument mappings
1207 - added new LSCP command "SET VOICES" to globally alter the maximum
1208 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1209 be triggered respectively
1210 - added new LSCP command "SET STREAMS" to globally alter the maximum
1211 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1212 which will be triggered respectively
1213 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1214 a gigedit file dialog is opened)
1215 - close all connections when LSCPServer is deleted
1216 - hard close of all sockets on exit
1217 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1218 driver
1219
1220 * Bug fixes:
1221 - fixed a crash which occurs when removing a sampler channel waiting
1222 to start instrument loading after another channel
1223 - fixed a crash which occurs when removing a sampler channel with
1224 instrument loading in progress (bug #113)
1225 - fixed termination caused by uncaught exception when adding MIDI
1226 instrument with PERSISTENT load mode
1227 - fixed possible iterator invalidations when resetting the sampler
1228 - fixed memory leaks when issuing the following LSCP commands:
1229 GET AUDIO_OUTPUT_DRIVER INFO
1230 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1231 GET MIDI_INPUT_DRIVER INFO
1232 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1233 - fixed possible compilation error when sqlite is not present
1234 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1235 - fixed crash when changing the audio output device of a sampler
1236 channel with loaded instrument and start playing notes
1237 - fixed endless loop in Engine::SuspendAll() (bug #120)
1238 - fixed a low-level atomic load function that was broken on 64-bit
1239 PowerPC, which probably could cause crashes on that platform
1240 - fixed a memory management error which could cause a crash when a
1241 plugin was unloaded
1242 - bugfix: two private structs had the same name, which could cause
1243 problems if the linker chose the wrong constructor
1244 - fixed low-level ConditionServer usage bug that caused lockups on
1245 Windows
1246
1247
1248 Version 0.5.1 (6 December 2007)
1249
1250 * packaging changes:
1251 - added autoconf checks for pthread library
1252 - added autoconf check for pthread bug found on certain NPTL-enabled
1253 glibc versions (see Gentoo bug report #194076)
1254 - added autoconf checks for MS Windows
1255
1256 * general changes:
1257 - bugfix: the thread used by an editor plugin didn't die when the
1258 editor closed
1259 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1260 out all the space. operator--() did not apply size_mask after
1261 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1262 order to avoid problems with the _NonVolatileReader functions.
1263 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1264 GetWriteSpace(). Since this function is currently only used in
1265 the stream's qsort() compare function, it didn't trigger any
1266 bugs.
1267 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1268 24bit mode too. Faster method to read 24bit words on little
1269 endian machines (x86): replaced 3 byte reads + shifts with a 1
1270 unaligned 32bit read and shift
1271 - experimental support for MS Windows (MIDI input via MME, AUDIO
1272 output via ASIO)
1273 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1274 - support for monitoring the total number of active disk streams
1275 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1276 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1277
1278 * AUDIO driver:
1279 - added Windows ASIO low latency audio driver
1280
1281 * MIDI driver:
1282 - added MME Windows MIDI driver
1283
1284 * LSCP server:
1285 - added support for Windows style path / filenames, however with
1286 forward slash path separators instead of backslash
1287 (i.e. "C:/foo/bar.gig")
1288 - allow naughty liblscp to send non-string device parameters within
1289 apostrophes as well
1290 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1291 "LIST FILE INSTRUMENTS <file>" and
1292 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1293 about an arbitrary instrument file on the system where the sampler is
1294 running on
1295
1296 Version 0.5.0 (15 October 2007)
1297
1298 * packaging changes:
1299 - config.h is not going to be installed along with liblinuxsampler's
1300 API header files anymore
1301 - only the API relevant header (and source) files will be exported to
1302 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1303 - added completely new XCode project files for Mac OSX which is now
1304 capable to execute our autoconf environment, thus no need anymore
1305 to maintain the compile time configuration file (osx/version.h) for
1306 OSX manually (patch by Toshi Nagata)
1307 - fixed buggy boolean --enable-foo / --disable-foo configure script
1308 parameters
1309 - global.h now only covers global definitions that are needed for the
1310 C++ API header files, all implementation internal global definitions
1311 are now in global_private.h
1312 - atomic.h is not exposed to the C++ API anymore
1313 - no need to include config.h anymore for using LS's API header files
1314 - fixed warnings in API doc generation
1315
1316 * general changes:
1317 - replaced the old, confusing MIDI program change mechanism by a
1318 flexible MIDI instrument mapper which allows to map arbitrary
1319 (MIDI bank, MIDI program) pairs with arbitrary
1320 (engine type, instrument file, file index) triplets which will be
1321 loaded on the respective channel when such MIDI program change
1322 messages arrive, beside that, each entry allows to define a life-time
1323 strategy for the instrument, so the user can define whether the
1324 instrument should i.e. be permanently loaded (to be able to switch
1325 quickly among sounds) or i.e. loaded just on demand when the
1326 respective program change arrives (to safe RAM space), as well as a
1327 global volume factor for each entry, so the user can adjust the volume
1328 dynamic of his mapped instrument collection without having to modify
1329 the instrument files, also one can manage arbitrary amount of such
1330 MIDI instrument maps and assign each sampler channel individually
1331 a certain map, so that i.e. separation of normal instruments and
1332 drumkits is possible
1333 - new notification events for tracking changes to audio/MIDI devices,
1334 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1335 - sampler was limited to load max. 200 instruments in the background
1336 due to a constant size RingBuffer FIFO which is now replaced by a
1337 dynamic (unlimited) size std::list FIFO
1338 - added FX sends, these allow to route audio signals to arbitrary audio
1339 output channels for being processed by external effect processors
1340 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1341 controllers
1342 - global (sampler wide) volume can now be controlled at runtime
1343 - Implemented new, improved notification system
1344 - fixed compilation errors regarding OSX
1345 (patch by Toshi Nagata)
1346 - implemented instruments database
1347 - added support for escape sequences to the instruments database
1348 - added highly experimental support for on-the-fly instrument editing
1349 within the sampler's process (by using instrument editor plugins),
1350 you'll notice the new "Registered instrument editors:" message on
1351 startup, added a new LSCP command:
1352 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1353 to spawn a matching instrument editor for the instrument on the
1354 given sampler channel, the plugin path can be overridden at compile
1355 time with ./configure --enable-plugin-dir=/some/dir
1356 - added experimental code for synchronizing instrument editors hosted
1357 in the sampler's process to safely edit instruments while playing
1358 without a crash (hopefully) by either suspending single regions
1359 wherever possible or if unavoidable whole engine(s)
1360 - fixed several issues in fundamental "Thread" class: set scheduling
1361 policy and priority on thread level, set a minimum stack size for
1362 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1363 threads simply inherited properties of starting thread instead of
1364 setting their own policy and priority
1365 - minor fix in our automatic stack trace mechanism on crashes, the
1366 main process did not wait for the stack trace process to finish
1367 its output
1368 - fixed some minor memory leaks
1369 - reenabled assembly features support, at the moment only for
1370 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1371 - minor assembly fix in x86 features detection (don't use the PIC
1372 register, to avoid relocations in the text segment at runtime)
1373 - POSIX callback functions of Thread.h are hidden
1374
1375 * MIDI driver:
1376 - dispatch bank select (MSB and LSB) messages
1377
1378 * audio driver:
1379 - the ALSA audio output driver parameters now reflect the correct
1380 parameter value ranges for the respective selected sound card
1381 (patch by Till Wimmer, a bit fixed and extended)
1382
1383 * Gigasampler format engine:
1384 - if a filter is used and EG2 finishes before EG1, let the voice
1385 die when EG2 has finished (this fixes a problem with clicks and
1386 voice starvation for some gigs)
1387 - playback is no longer disabled during instrument loading
1388 - all notes playing on a channel that changes its instrument keep
1389 playing with the old instrument until they get a note off
1390 command
1391 - EG fix: a release value of zero could cause noises or crash
1392 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1393 - EG fine tuning: when attack is zero the EG starts at a level
1394 above max sustain level, which means that there is a decay phase
1395 even if sustain is 100%
1396 - more EG fixes: the level could sometimes go below zero and cause
1397 noises or crashes
1398 - minor fix of EGDecay (patch by Toshi Nagata)
1399 - fixed compiler error when --enable-override-filter-type was
1400 supplied to the configure script (fixes #46)
1401 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1402 instead of a fix value
1403 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1404 127 (solo mode) only kill voices if the respective mode really
1405 changed
1406
1407 * LSCP server:
1408 - fixed compile time error for old Bison versions
1409 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1410 - parser now supports extended ASCII character set
1411 (up to ASCII code 255, i.e. includes now umlauts and accents)
1412 - filename arguments in LSCP commands now allow to use escape
1413 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1414 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1415 code value like \xf2) (fixes bug #24)
1416 - the following LSCP commands now also support escape sequences for at
1417 least one of their text-based parameters (i.e. name, description):
1418 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1419 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1420 "SET DB_INSTRUMENT_DIRECTORY NAME",
1421 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1422 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1423 "FIND DB_INSTRUMENT_DIRECTORIES"
1424 - returns verbose syntax errors (line and column where syntax error
1425 occured, the unexpected character and the actually expected, possible
1426 character(s), the latter only if less than 5 possibilities)
1427 - made sure that LSCP syntax is not affected by gigedit locale
1428 settings
1429 - bugfix regarding strings parameter lists: all comma separated lists
1430 of strings were treated as being one string containing commas
1431 (fixes #57)
1432
1433 * Bug fixes:
1434 - fixed crash occurring on certain LSCP scripts (Bug 39)
1435 - another thread safety fix for lscp "load engine" and "set
1436 channel audio output device"
1437 - fixed a crash which occurs when reassigning the same engine
1438 on a sampler channel with connected MIDI device
1439 - fixed a crash which occurs when changing the number of ports of a MIDI
1440 device connected to a sampler channel to number less then or equal
1441 to the index of the port to which the sampler channel is connected.
1442 - The previous bindings were not been disconnected when altering
1443 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1444 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1445 - The active stream/voice count statistic was incorrect.
1446 - notification events were not been sent for some sampler
1447 channel changes
1448 - added default min and max values to restrict the number of allowed
1449 audio output channels and MIDI input ports
1450 - the connection to the PCM interface is now closed when destroying
1451 an audio output device
1452 - files with slash in their path or filename could not be loaded
1453
1454 * test cases:
1455 - updated and fixed (haven't been touched in a while)
1456
1457 Version 0.4.0 (24 November 2006)
1458
1459 * packaging changes:
1460 - changed deprecated copyright attribute to license; added ldconfig
1461 to post-(un)install steps; added devel package for liblinuxsampler;
1462 to linuxsampler.spec (RPM)
1463 - install necessary development header files for allowing 3rd party
1464 applications to link against liblinuxsampler
1465 - liblinuxsampler's API documentation can be generated with 'make docs'
1466 (Doxygen required)
1467 - added benchmark to automatically detect the best triangle LFO
1468 implementation (currently either an integer math solution or a
1469 di-harmonic approximation), automatic detection can be overriden
1470 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1471 configure script argument though (mandatory for cross-compilation)
1472 - do not automatically pick optimized gcc flags if the user already
1473 provided some on his own (as CXXFLAGS)
1474 - added compile time option to disable processing of All-Notes-Off MIDI
1475 messages
1476 - added compile time options to allow disabling the various audio and
1477 MIDI drivers
1478 - fixed automatic GCC CPU switch detection on PPC
1479 (patch by Ebrahim Mayat)
1480
1481 * Gigasampler format engine:
1482 - extensive synthesis optimization
1483 (reimplementation of EGs and LFO(s), removed synthesis parameter
1484 prerendering and the synthesis parameter matrix in general, splitting
1485 each audio fragment into subfragments now where each subfragment uses
1486 constant pitch and filter coefficients. The volume coefficient is
1487 linearly interpolated inside a subfragment, unless
1488 --disable-interpolate-volume is set.)
1489 - fine tuning of the EG modulation parameters
1490 - improved filter cutoff calculation by adding support for the
1491 following gig parameters: Cutoff freq (used when no cutoff
1492 controller is defined), Control invert, Minimum cutoff, Velocity
1493 curve and Velocity range. The keyboard tracking now scales
1494 cutoff frequency instead of resonance.
1495 - added support for gig parameter Resonance.
1496 - fixed bug in sysex handling (patch by Juan Linietsky)
1497 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1498 which can be overridden with --enable-global-attenuation
1499 - EG fixes: made the length of "attack hold" stage more
1500 accurate. Release stage can now start before attack stage
1501 ends. Cancel release didn't work when sustain was zero. Attack
1502 time now has a minimal value to prevent clicks.
1503 - fixed pitch changes larger than one octave
1504 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1505 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1506 all modes can be altered via standard GM messages, that is CC5 for
1507 altering portamento time, CC65 for enabling / disabling portamento
1508 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1509 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1510 parameter) and crossfade
1511 - added support for the "attenuation controller threshold" gig
1512 parameter
1513 - added smoothing of volume changes caused by control change
1514 messages
1515 - sample loop parameters are now taken from the DimensionRegion
1516 instead of the wave chunk
1517 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1518 not equal to a power of two
1519 - reimplementation of the filter algorithm. The new filter is more
1520 accurate and supports all gig filter types, including bandreject
1521 and lowpass turbo.
1522 - real support for 24 bit samples - samples are not truncated to
1523 16 bits anymore
1524 - support for aftertouch (channel pressure, not polyphonic
1525 aftertouch)
1526 - LFO1 behaviour fixed (dampening from max volume instead of
1527 amplifying from 0)
1528
1529 * LSCP server:
1530 - fixed application exit on broken pipe error (fixes bug #20)
1531 - fixed the notification messages delay due to lack of
1532 network activity (fixes bug #26)
1533 - fixed parser bug which occured on space(s) within device parameters
1534 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1535
1536 * audio driver:
1537 - added aRts audio output driver (by no means RT safe)
1538
1539 * MIDI driver:
1540 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1541 messages several times instead of once
1542 - API extension for MIDI drivers which already supply exact time stamps
1543 for events (i.e. for offline rendering based MIDI drivers)
1544 - added checks for bad MIDI data
1545
1546 * linuxsampler application:
1547 - show available sampler engine types on startup
1548
1549 * general changes:
1550 - support for muting sampler channels and solo mode of the same, two new
1551 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1552 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1553 introduced for this, the behavior is the same like on a mixer console
1554 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1555 --enable-process-muted-channels which can be used to enable the
1556 processing of muted channels.
1557 - support for sostenuto pedal
1558 - support for monitoring the total number of active voices
1559 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1560 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1561 - fixed some memory management errors
1562 - fixed some concurrency problems that could lead to crashes when
1563 LSCP commands were executed
1564 - fixed crash when instrument loading failed previously on the same
1565 sampler channel (fixes bug #36)
1566
1567 Version 0.3.3 (15 July 2005)
1568
1569 * packaging changes:
1570 - fixed compilation with gcc 4.0
1571
1572 * Gigasampler format engine:
1573 - LFO preprocessing was performed even though the respective LFO was
1574 disabled by the instrument patch (minor efficiency fix)
1575 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1576 for volume ramp downs in the same fragment (needed for current voice
1577 stealing implementation) then simply inform the user with a warning
1578 about possible click sounds and reduce the volume ramp down
1579 appropriately instead of cancelling the audio device connection
1580
1581 Version 0.3.2 (24 June 2005)
1582
1583 * packaging changes:
1584 - updated autotools build files to compile on OS X
1585 (conditional compilation of CoreMIDI and MidiShare drivers)
1586 - hand-crafted assembly optimization code can be disabled with
1587 './configure --disable-asm' (definitely not recommended)
1588 - fixed 'make dist' rule to include all necessary files
1589 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1590 (due to 'dist-bzip2' automake option)
1591
1592 * Gigasampler format engine:
1593 - support for the gig parameters for "release velocity response" curves
1594 - fine tuning of the EGADSR envelope
1595 - volume of release triggered samples now depends on note-on velocity,
1596 note length and gig parameter "release trigger decay" instead of
1597 note-off velocity.
1598 - revised voice stealing
1599 (fixes crash and endless loop caused by voice stealing)
1600 - don't reset scale tuning on instrument or audio output device change
1601 - handle key group conflicts right at the beginning of each fragment
1602 instead of when the respective voice is actually launched
1603 (fixes undefined behavior if stolen voices belonged to a key group -
1604 this case was followed by a "killed voice survived" error message)
1605 - fixed minor issue with null/silence samples
1606 (those stole voices even though they don't need a voice at all which
1607 resulted in "voice stealing didn't work out" messages)
1608 - don't reset volume, pan, pitch and MIDI controller values on
1609 instrument or audio output device change
1610
1611 * LSCP server:
1612 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1613 - fixed LSCP event "CHANNEL_INFO" notification
1614 (e.g. did not notify on volume changes or MIDI program change events)
1615
1616 * linuxsampler application:
1617 - added command line parameters --lscp-addr and --lscp-port to override
1618 default IP address and port of LSCP server
1619
1620 Version 0.3.1 (24 May 2005)
1621
1622 * initial release
