NKSP: Added support for 'patch' variables.

* NKSP language: Added support for 'patch' variable qualifier
  (as new dedicated keyword 'patch').

* NKSP parser: capture locations of 'patch' variable declarations
  in script's source code.

* ScriptVM: Allow patching 'patch' script variables by replacing
  their default assignment expression with a supplied replacement
  variable initialization expression by optional 2nd argument when
  calling loadScript().

* ScriptVM: Allow retrieval of default initialization expressions
  of all 'patch' variables by optional 3rd argument when calling
  loadScript() (i.e. for instrument editors).

* gig engine: Implemented support for loading real-time instrument
  scripts with 'patch' variables bundled with gig instruments.

* Bumped version (2.1.1.svn46).


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 - Added public API C++ class "LFO", which is a cluster class encapsulating
14 all the sampler's LFO implementations to be used by 3rd party applications
15 (e.g. by Gigedit).
16 - Added int math square LFO implementation.
17 - Added int math saw LFO implementation.
18 - Added numeric complex nr sine LFO implementation.
19 - Marked class LFOTriangleDiHarmonic as deprecated
20 (will be removed in future).
21 - Added LFOAll.h which includes all LFO implementation's header files.
22 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25 SquareLFO -> LFOSquarePulse and separated the latter to its own header
26 file).
27 - Renamed type LFOSigned -> LFOTriangleSigned.
28 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29 - Using now cubic interpolation as resampling algorithm by default; and
30 linear interpolation is deprecated now.
31 - Event:Init(): memset() entire Event::Param union to zero instead of trying
32 to do that for its individual members; the latter became error prone due
33 to the union's growing complexity meanwhile.
34 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36 methods and marked the old ones as deprecated; and likewise added new
37 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38 methods and marked those old ones deprecated as well.
39 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41 - Implemented support for compressed RPN/NRPN message sequences (that is to
42 allow processing MIDI data entry messages without always having to be
43 preceded strictly by RPN/NRPN parameter selection messages on each value
44 change).
45 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46 decrement).
47 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48 MSB=127 and LSB=127) and which is disabling subsequent data
49 entry/increment/decrement CC messages.
50 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51 instrument editor.
52 - Fixed playing noise at the end of a disk stream under certain conditions.
53 - Fixed potential crash with high pitch at end of RAM playback.
54
55 * Real-time instrument scripts:
56 - Added method ScriptVM::setExitResultEnabled() which allows to
57 explicitly enable the built-in exit() function to optionally accept
58 one function argument; the value of the passed exit() function
59 argument will then become available by calling
60 VMExecContext::exitResult() after script execution.
61 - 64 bit support for NKSP integer scripts variables (declare $foo).
62 - Variable names, function names and preprocessor condition names must start
63 with a regular character (a-z or A-Z); starting them with a digit or
64 underscore is not allowed.
65 - NKSP parser fix: equal comparison operator "=" and not equal comparison
66 operator "#" must only accept integer operands.
67 - NKSP language: Implemented support for standard units like Hertz, seconds,
68 Bel including support for metric unit prefixes; so one can now e.g.
69 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
70 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
71 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
72 - NKSP language: Introduced "final" operator "!" which is specifically
73 intended for synthesis parameter values to denote that the synthesis
74 parameter value is intended to be the "final" value for that synthesis
75 parameter that should explicitly be used by the engine and thus causing
76 the sampler engine to ignore all other modulation sources for the same
77 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
78 variable or formula with this new "!" operator the expression is marked as
79 being "final".
80 - NKSP script editor API: Added support for detecting standard unit tokens
81 and their potential metric prefix token.
82 - NKSP language: Added support for NKSP real number literals and
83 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
84 - NKSP language: Added support for NKSP real number (floating point) script
85 variables (declare ~foo).
86 - NKSP language: Added support for NKSP real number (floating point) array
87 script variables (declare ?foo[]).
88 - Built-in script function "message()" accepts now real number argument as
89 well.
90 - Added built-in script function "real_to_int()" and its short hand form
91 "int()" for casting from real number to integer in NKSP scripts.
92 - Added built-in script function "int_to_real()" and its short hand form
93 "real()" for casting from integer to real number in NKSP scripts.
94 - Allow built-in exit() function to potentially accept real number type
95 argument as well.
96 - Built-in script functions may have a different return type depending on
97 the arguments passed to the function.
98 - Built-in script function "abs()" optionally accepts and returns real
99 number.
100 - Built-in script functions "min()" and "max()" optionally accept real
101 number arguments and return real number as result in that case.
102 - NKSP VM API: Allow units and 'final'ness to be returned as result from
103 built-in functions (added methods VMFunction::returnUnitType() and
104 VMFunction::returnsFinal() for that purpose which must be implemented by
105 built-in function implementations).
106 - NKSP language: Allow metric unit prefixes of numeric scalar and array
107 variables to be changed freely at runtime (unlike unit types like Hz etc.
108 which are still sticky, parse-time features of variables which cannot be
109 changed at runtime for the intentional sake of determinism).
110 - NKSP language: 'final' values are prohibited for array variables for now
111 (attempt causes a parsers error).
112 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
113 conditions of runtime control structures like if(), while(), select()
114 (attempt causes a parser error).
115 - NKSP VM API: Allow built-in functions to perform their own, individual
116 parse time checks of arguments going to be passed to the function at
117 runtime (added method VMFunction::checkArgs() for that purpose).
118 - NKSP language: raise parser warning if only one operand of binary
119 operators (like logical 'or' comparison) contain a 'final' value (because
120 it would always yield in a 'final' result in such cases).
121 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
122 different metric unit prefixes, which will behave as expected (e.g.
123 result of expression '1000us < 2ms' is true).
124 - NKSP language: Allow adding values with different metric unit prefixes
125 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
126 - NKSP language: Allow subtracting values with different metric unit
127 prefixes (e.g. result of expression '1ms - 20us' is '980us').
128 - NKSP language: Allow multiplying with any metric unit prefixes
129 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
130 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
131 we don't have any considerable practical use for a term like '4s^2'
132 (hence any attempt multiplying two unit types still causes parser error).
133 - NKSP language: Allow dividing by any metric unit prefixes and allow
134 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
135 yields in unit free result '8'). So this is now a way to cast units away
136 e.g. for passing the result to other expressions, certain function calls
137 or variables which are not accepting any units (or that specific unit).
138 - NKSP language: integer arrays and real number arrays can now be converted
139 to strings (e.g. for dumping their content with message() calls for
140 script debugging purposes).
141 - NKSP language: expressions and variables with units are now correctly
142 casted to strings (e.g. with message() calls).
143 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
144 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
145 floating point tolerances into account.
146 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
147 VMScalarNumberExpr::evalCastReal().
148 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
149 'VMIntArrayExpr' and 'VMRealArrayExpr'.
150 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
151 unitFactor() (runtime) methods.
152 - Built-in function "exit()" supports now returning units and 'final'ness
153 for test cases.
154 - The following built-in functions support now units as well: "abs()",
155 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
156 "real_to_int()", "int()", "int_to_real()" and "real()".
157 - Built-in functions "array_equal()", "search()" and "sort()" support now
158 real number arrays (correctly) as well.
159 - Added individual parse time checks of arguments to be passed to built-in
160 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
161 "array_equal()" and "search()" specific for their individual purposes.
162 - NKSP VM refactoring: Renamed all methods, functions and classes matching
163 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
164 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
165 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
166 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
167 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
168 isScalarNumber() -> isNumber()).
169 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
170 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
171 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
172 as convenient methods for automatically converting values to expected
173 metric value basis.
174 - Built-in function "wait()" accepts now both integers and real numbers as
175 argument.
176 - NKSP VM API cleanup: Get rid of legacy method
177 VMFunction::argType(vmint iArg) which was already superseded by its new
178 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
179 - NKSP parser: if wrong argument type was passed to a built-in function and
180 that built-in function accepts more than one data type for the argument,
181 then show all supported data types as parser error message.
182 - Built-in function "play_note()" accepts now real numbers and seconds as
183 unit type as well for its 3rd and 4th function arguments.
184 - The following built-in functions accept now real numbers as well for their
185 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
186 "change_attack()", "change_decay()", "change_release()",
187 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
188 "change_cutoff_sustain()", "change_cutoff_release()",
189 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
190 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
191 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
192 - Fixed built-in function "change_play_pos()" not having accepted metric
193 prefixes at all.
194 - Fixed the following built-in functions having misinterpreted values given
195 with unit type (for their 2nd argument) as if they were relative values
196 (that is as if they were passed without a unit type): "change_attack()",
197 "change_decay()", "change_release()", "change_cutoff_attack()",
198 "change_cutoff_decay()", "change_cutoff_release()".
199 - Fixed the following built-in functions having applied completely wrong
200 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
201 respective EGs being their modulation sink assume uint data type with
202 value range 0..1000 instead of 0.0..1.0.
203 - Added individual parse-time checks of function arguments for the following
204 built-in functions: "play_note()", "note_off()", "set_event_mark()",
205 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
206 "change_decay()", "change_release()", "change_cutoff_attack()",
207 "change_cutoff_decay()", "change_cutoff_release()",
208 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
209 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
210 "change_pan_time()".
211 - Don't abort function call if unit type was used and at the same time
212 'final' operator was omitted for the primary value argument of the
213 following built-in functions: "change_cutoff()", "change_attack()",
214 "change_decay()", "change_release()", "change_cutoff_attack()",
215 "change_cutoff_decay()", "change_cutoff_release()",
216 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
217 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
218 "change_pan_time()", instead imply 'final'ness at runtime and raise an
219 appropriate parser warning at parse time.
220 - Added built-in real number functions "round()", "ceil()", "floor()",
221 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
222 "cos()", "tan()", "asin()", "acos()", "atan()".
223 - Added built-in script real number constant "~NI_MATH_PI".
224 - Added built-in script real number constant "~NI_MATH_E".
225 - NKSP language: Allow unary '+' operator.
226 - Added built-in script functions "msb()" and "lsb()".
227 - NKSP language: Added support for RPN event handler
228 ("on rpn ... end on" in instrument scripts).
229 - NKSP language: Added support for NRPN event handler
230 ("on nrpn ... end on" in instrument scripts).
231 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
232 may be read from the new RPN/NRPN script handlers to get the (N)RPN
233 parameter that had been changed and its new value.
234 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
235 which are identifying the new (N)RPN handlers as such at script runtime.
236 - Implemented built-in script function "set_rpn()".
237 - Implemented built-in script function "set_nrpn()".
238 - Fix: built-in functions returning an array type were broken and caused a
239 crash when the built-in function's (supposed to be array) result value was
240 used by the script VM.
241 - Removed upper value constraint for 2nd argument of built-in functions
242 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
243 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
244 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
245 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
246 the LFO frequency / resonance / cutoff frequency.
247 - Reduced code involved for parsing NKSP variable declarations by using 2
248 generalized grammar rules with optional components (i.e. optional value
249 assignment and optional variable qualifiers) instead of previous linear
250 combinations of grammar rules, which also fixes some edge case.
251 - NKSP language parser: track code block locations also by a) raw byte
252 position in NKSP source code string and b) length of that code block in
253 bytes (along to the already existing code block tracking by line/column);
254 and added appropriate new members to public C++ API classes like
255 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
256 - NKSP language: Added support for 'patch' variable qualifier (capture their
257 locations and allow replacement of their assignment expression via VM C++
258 API).
259
260 * test cases:
261 - Fixed compiler errors in test cases.
262 - Updated README for how to compile & run test cases.
263 - Updated test case
264 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
265 expected behaviour of the Mutex class implementation (recursive
266 mutex type).
267 - Added test cases for NKSP core language aspects and core built-in
268 functions.
269 - Fixed thread tests segfaulting on Linux.
270 - NKSP: Added real number test cases for built-in functions exit(),
271 int_to_real(), real(), real_to_int() and int(), as well as for the
272 plus, minus and negate language operators.
273 - Added massive amount of NKSP test cases for standard measuring units and
274 'final' operator usage cases.
275 - Added NKSP test cases for (floating point tolerance aware) real number
276 equalness / unequalness comparison.
277 - Added NKSP int array and real array tests for value assignment and
278 initialization of arrays.
279 - Added NKSP test cases for built-in functions "round()", "ceil()",
280 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
281 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
282 - Added NKSP test cases for unary '+' operator.
283 - Added NKSP test cases for core built-in variables.
284 - Added thorough NKSP test cases for variable declarations.
285
286 * GigaStudio/Gigasampler format engine:
287 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
288 behaviour for start_level_mid.
289 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
290 level (see discussion "GigaStudio LFO compatibility" on mailing list
291 from 2019-09-26 for details).
292 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
293 see discussion "GigaStudio LFO compatibility" on mailing list from
294 2019-09-26 for details).
295 - Format extension: Added support for different LFO wave forms (currently
296 either sine [default], triangle, saw or square).
297 - Format extension: Added support for LFO phase displacement (0��..360��).
298 - Format extension: Added support for flipping LFO polarity on LFO 3
299 (in the original gig format this was only available for LFO 1 and LFO 2).
300 - Format extension: Support for additional filter types:
301 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
302 bandreject 2-pole.
303 - Fixd potential crash with polynomial interpolator and max. pitch.
304 - If minimum cutoff is defined, remap cutoff controller CC values to really
305 span the entire possible cutoff range (and avoiding a dead controller
306 zone).
307 - Implemented support for loading instrument scripts with 'patch' variables
308 (by patching these script variables with potentially overridden ones by
309 gig Instrument).
310
311 * SFZ format engine:
312 - Fixed support for regions with loccN/hiccN conditions on more than one
313 MIDI controller.
314
315 * Benchmarks:
316 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
317 algorithm (since result of 2nd run was not accumulated).
318 - Added benchmark for saw wave (benchmarks/saw.cpp).
319 - Added benchmark for sine wave (benchmarks/sine.cpp).
320 - Added benchmark for square wave (benchmarks/square.cpp).
321 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
322 which are large enough on modern systems.
323
324 Version 2.1.1 (27 Jul 2019)
325
326 * Real-time instrument scripts:
327 - Fixed behavior of built-in NKSP functions change_sustain(),
328 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
329 and change_cutoff_release().
330
331 * general changes:
332 - Only play release trigger samples on sustain pedal up if this behaviour
333 was explicitly requested by the instrument (otherwise only on note-off).
334 - Fixed compiler warnings.
335 - Fixed compilation error when cross-compiling to Mac.
336 - FX Sends: Provide more useful error messages on routing problems
337 (see bug #169).
338 - LSCP doc: Be more clear describing the two distinct approaches
339 of using external vs. internal effects (see bug #169).
340 - "optional" class: Fixed comparison operators.
341
342 * Gigasampler/GigaStudio format engine:
343 - Format extension: If requested by instrument then don't play release
344 trigger sample on note-off events.
345
346 * SFZ format engine:
347 - Fixed memory leak when releasing samples
348 (fixes bug #307, patch by Jacek Roszkowski)
349 - Fixed potential crash when a sample is shared by more than one region
350 (fixes bug #308, patch by Jacek Roszkowski).
351 - Opcode 'sample': Added support for built-in sample '*silence'
352 (fixes bug #310, patch by Jacek Roszkowski).
353
354 Version 2.1.0 (25 Nov 2017)
355
356 * SFZ format engine:
357 - added support for <global>, <master> and #define (patch by Alby M)
358 - Removed code duplication in SFZ file loading code.
359 - Added support for sfz extension opcode 'script' which may be used to
360 load real-time instrument script file (NKSP script language).
361 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
362 - Fixed unintended volume fade-in of voices under certain conditions.
363 - sfz parser: allow missing space between header and opcode
364
365 * Gigasampler/GigaStudio format engine:
366 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
367 cutoff settings.
368 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
369 all if an up-pitch of more than 40 semi tones was requested (I don't
370 think there is any stock gig sound that requires this behavior to
371 resemble its original sound).
372 - Added support for controlling whether the individual EGADSR stages may
373 be aborted (as LinuxSampler extension to the original GigaStudio 4
374 format).
375
376 * general changes:
377 - fixed printf type errors (mostly in debug messages)
378 - use unique_ptr instead of auto_ptr when building with C++11
379 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
380 allowing to sort data efficiently in real-time safe manner.
381 - RTList class: added methods for moving/inserting elements to arbitrary
382 position within a list.
383 - RTList class: added method fromPtr() for creating an Iterator object from
384 a raw element pointer.
385 - Attempt to partly fix resetting engine channels vs. resetting engine, an
386 overall cleanup of the Reset*(), ConnectAudioDevice(),
387 DisconnectAudioDevice() API methods would still be desirable though,
388 because the current situation is still inconsistent and error prone.
389 - Active voices are now internally grouped to "Note" objects, instead of
390 being directly assigned to a keyboard key. This allows more fine graded
391 processing of voices, which is i.e. required for certain instrument
392 script features.
393 - Fix: Release trigger voices were not spawned on sustain pedal up
394 (CC #64) events.
395 - Fix: Release trigger voices can now also distinguish correctly between
396 note-off and sustain pedal up events.
397 - All engines: Increased ramp speed of volume smoother and pan smoother
398 (while slow rate of crossfade smoother is preserved) to allow quick
399 volume and pan changes by instrument scripts for instance.
400 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
401 properly and thus were ignored for certain uses.
402 - Added new C++ API method
403 VirtualMidiDevice::SendChannelPressureToSampler().
404 - windows, 32-bit: fixed potential crashes by making sure the stack in
405 sub threads is 16-byte aligned
406 - fixed numerous compiler warnings
407 - Fixed invalid (note-on) event ID being assigned to new Note objects.
408 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
409 fixes potential undefined behavior.
410 - Fixed Note object leak when triggering notes on keys which did not
411 have a valid sample mapped (fixes bug #252).
412 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
413 - linuxsampler binary fix: option --create-instruments-db ignored
414 subsequent optional argument due to glibc's implementation oddity
415 which expects a "=" sign, but no space between them.
416
417 * packaging changes:
418 - removed unnecessary dependency to libuuid
419 (originated by libgig's usage of it)
420 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
421 auto detect whether it (sh/c)ould output its messages in color.
422 - Debian: Fixed packaging error about invalid "Source-Version"
423 substitution variable.
424 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
425 - Debian: Added build dependency to libsqlite3-dev for building
426 linuxsampler with instruments DB support.
427
428 * Real-time instrument scripts:
429 - Implemented scheduler for delayed MIDI events and for suspended scripts.
430 - Built-in script function "wait()": implemented support for function's
431 "duration-us" argument, thus scripts using this function are now
432 correctly resumed after the requested amount of microseconds.
433 - Built-in script function "play_note()": implemented support for
434 function's "duration-us" argument, thus notes triggered with this
435 argument are now correctly released after the requested amount of
436 microseconds.
437 - Fix: script events were not cleared when engine channel was reset,
438 potentially causing undefined behavior.
439 - Fixed crash which happened when trying to reference an undeclared
440 variable.
441 - Built-in script function "play_note()": Added support for passing
442 special value -1 for "duration-us" argument, which will cause the
443 triggered note to be released once the original note was released.
444 - Instrument script classes now exported with the liblinuxsampler C++ API.
445 - Added new API method ScriptVM::syntaxHighlighting() which provides
446 a convenient syntax highlighting backend for external instrument
447 script editor applications.
448 - Added new C++ API class "ScriptVMFactory".
449 - Extended parser issues to provide not only first line and first
450 column, but also last line and last column of issue (thus marking
451 the precise span of the issue within the source code).
452 - Reload script automatically after being modified by an instrument
453 editor.
454 - NKSP language grammar correction: allow empty event handler bodies
455 like "on note end on".

461 - Implemented built-in script function "event_status()".
462 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
463 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
464 "event_status()" function.
465 - NKSP language: Added support for bitwise operators ".or.", ".and."
466 and ".not.".
467 - NKSP language scanner: Fixed IDs matching to require at least one
468 character (i.e. when matching function names or variable names).
469 - NKSP language scanner: disabled unusued rules.
470 - Fixed behavior of play_note() and note_off() functions which must
471 be distinguished engine internally from "real" MIDI note on/off
472 events in order to avoid misbehaviors like hanging notes.
473 - Implemented built-in script variable "$KSP_TIMER".
474 - Implemented built-in script variable "$NKSP_REAL_TIMER".
475 - Implemented built-in script variable "$NKSP_PERF_TIMER".

479 - NKSP language fix: division expressions were evaluated too often.
480 - NKSP language fix: string concatenation operator was right
481 associative instead of left (to right).
482 - NKSP language correction: allow empty statements in entire language
483 (i.e. "if end if").
484 - Implemented built-in script function "stop_wait()".

496 - Implemented built-in script function "change_decay()".
497 - Implemented built-in script function "change_release()".
498 - Fixed all change_*() built-in script functions to apply their
499 synthesis parameter changes immediately in case the respective note
500 was triggered at the same time, instead of scheduling the parameter
501 change, especially because it would cause some parameter types's
502 changes either to be ramped (i.e. change_vol()) or other types even
503 to have not effect at all (i.e. change_attack()).
504 - Implemented built-in script function "sh_left()".
505 - Implemented built-in script function "sh_right()".
506 - Implemented built-in script function "min()".
507 - Implemented built-in script function "max()".
508 - NKSP Fix: "init" event handler was not always executed when a script
509 was loaded.
510 - NKSP built-in wait() script function: abort script execution if
511 a negative or zero wait time was passed as argument (since this is
512 a common indication of a bug either of the script or even of the
513 engine, which could lead to RT instability or even worse).
514 - ScriptVM: Implemented automatic suspension of RT safety
515 threatening scripts.
516 - Provide more user friendly error messages on syntax errors.
517 - Fixed NKSP parser warning "Not a statement" when assigning an
518 initializer list to an array variable.

524 - Implemented built-in script function "change_pitch_lfo_freq()".
525 - Implemented built-in script function "change_vol_time()".
526 - Implemented built-in script function "change_tune_time()".
527 - Implemented built-in script function "fade_in()".
528 - Implemented built-in script function "fade_out()".
529 - Fixed acceptance of wrong data type of parameters passed to built-in
530 script functions "change_vol()", "change_tune()", "change_pan()",
531 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
532 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
533 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
534 - Added built-in script function "get_event_par()" and implemented some
535 of its possible parameter selections.
536 - Added built-in script function "set_event_par()" and implemented some
537 of its possible parameter selections.
538 - Fixed a bunch of scheduler time related bugs.
539 - Fixed polyphonic variables not being reset to zero after usage.
540 - Built-in "ignore_event()" function: argument is now optional, like with
541 built-in function "ignore_controller()".
542 - Implemented built-in script function "change_velo()".
543 - Implemented built-in script function "change_note()".
544 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
545 intuitive behavior if used in combination with "change_vol_time()" or
546 "change_tune_time()" respectively: now tuning/volume changes are only
547 assigned (without delay) immediately to a new note if the respective
548 timing function has not been called before, otherwise the volume/tuning
549 changes are automatically faded (before, only the event's time stamp was
550 relevant).
551 - Implemented built-in script function "array_equal()".
552 - Implemented built-in script function "search()".
553 - Implemented built-in script function "sort()".
554 - NKSP Fix: Never suspend "init" event handlers.
555 - Implemented built-in script function "same_region()" (currently only
556 available for gig format engine).
557 - Added built-in script constant "$NKSP_LINEAR".
558 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
559 - Implemented built-in script function "change_vol_curve()".
560 - Implemented built-in script function "change_tune_curve()".
561 - built-in "play_note()" function now supports a sample playback start
562 offset with argument 3, where special value -1 means to use the regular
563 sample offset as defined by the instrument file.
564 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
565 - Built-in variable $EVENT_NOTE is now a read-only variable.
566 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
567 - built-in "play_note()" function now accepts -2 for its fourth argument
568 (note duration) which means the life time of the note shall be sticked
569 to the requested note number of argument 1.
570 - Fix: built-in "play_note()" function now returns 0 as result value if
571 -1 was passed for its fourth argument (note duration) and the respective
572 parent note is already gone.
573 - Implemented built-in script function "change_play_pos()".
574 - NKSP language: Added support for user declared const array variables.
575 - NKSP language: Raise parser warning if array variable is accessed with
576 an index that exceeds the array's size.
577 - NKSP language fix: Unknown characters were not handled correctly.
578 - NKSP language: Added support for "synchronized .. end synchronized"
579 code blocks.
580 - Implemented built-in script function "abort()" which allows to abort
581 another script handler by passing its callback ID.
582 - Fixed potential memory access bug and potential undefined behavior of
583 "init" event handlers.
584 - Print a time stamp along to each call of built-in function "message()".
585 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
586 to retrieve all code blocks filtered out by the preprocessor.
587 - Added built-in script function "fork()".
588 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
589 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

591 - Added built-in script function "callback_status()".
592 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
593 - Added built-in constant $CALLBACK_STATUS_QUEUE.
594 - Added built-in constant $CALLBACK_STATUS_RUNNING.
595 - Removed max. value limitation of built-in functions "change_attack()",
596 "change_decay()" and "change_release()" to i.e. allow passing 2000000
597 for doubling the respective time.
598 - NKSP script editor syntax highlighting API: Fixed app termination due
599 to a lexer start condition stack underrun.
600 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
601 USE_CODE_IF_NOT() preprocessor statements.
602 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
603 can be set to disable all subsequent built-in "message()" function calls
604 on preprocessor level.
605 - Implemented built-in script function "change_sustain()".
606 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

624 - Added support for scanning Sound Font (.sf2) files.
625 - Fixed undefined DB transaction behavior.

639 - minor Makefile fix for building lscpparser when build and source
640 directories are separate
641 - Mac OS X: made it possible to specify plugin installation dir to
642 configure
643 - Mac OS X: Makefile fix for the install-strip target
644 - fixed compilation with gcc 4.7
645 - fixed configure script error with old autoconf versions
646 - lsatomic.h: use gcc provided atomic functions if building with
647 gcc 4.7 and C++11
648 - modernized configure script
649 - fixed linkage error when building with
650 LDFLAGS="-Wl,--no-undefined" (#190)
651 - fixed compilation with Clang 3.2
652 - removed usage of deprecated Automake variable INCLUDES
653 - fixed building with C++11
654 - build fix: ChangeFlagRelaxed.h was missing in makefile
655 - build fix: libsndfile compiler flags were missing in some
656 makefiles
657 - fix for building with bison 3.0 (#202)
658 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
659 on the process's main thread
660 - fixed build error on newer MinGW
661 - support building with older jack versions

665 in order to get rid of warnings from automake 1.14
666
667 * general changes:
668 - Refactoring: moved the independent code from
669 the Gigasampler format engine to base classes
670 - command line option '--profile' is currently disabled, since the
671 respective profiling code is currently broken
672 - Introduced support for optional environment variable
673 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
674 where the sampler shall look for instrument editor plugins
675 (patch by Luis Garrido, slightly modified).
676 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
677 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
678 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
679 note (in this implementation of the sampler its simply hard routed to
680 the 1st effect send of the sampler channel, no matter what the actual
681 effect type is)
682 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
683 note (in this implementation of the sampler its simply hard routed to
684 the 2nd effect send of the sampler channel, no matter what the actual
685 effect type is)
686 - implemented support for internal LADSPA effects
687 - raised limit of program change queue from 100 to 512
688 (as suggested by Alex Stone)
689 - implemented sine LFO, pulse LFO and saw LFO
690 - experimental support for per voice equalization
691 - added command line option --exec-after-init
692 - Introduced new C++ API method:
693 EngineChannel::InstrumentFileName(int index)
694 allowing to retrieve the whole list of files used for the loaded
695 instrument on an engine channel (a.k.a. part). Some GigaStudio
696 instruments for example are splitted over several files like
697 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
698 - Added new C++ API method Sampler::GetGlobalMaxVoices().
699 - Added new C++ API method Sampler::GetGlobalMaxStreams().
700 - Added new C++ API method Sampler::SetGlobalMaxVoices().
701 - Added new C++ API method Sampler::SetGlobalMaxStreams().
702 - Various "const" and "restrict" optimizations.
703 - all engines: add pan CC value to instrument pan parameter before
704 applying panning, instead of using two separate pan functions in
705 series (#182)
706 - added a lock guard class for exception safe mutex handling and
707 used it everywhere appropriate
708 - Immediately apply scale tuning changes to active voices.
709 - Exposed scale tuning to C++ API (along to the already existing standard
710 SysEx way).
711 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
712 and broken for ppc64. (Seq_cst loads and stores are actually not
713 used in LS, so the bug wasn't noticable.)
714 - lsatomic.h: added ARMv7 support
715 - Added support for multiple MIDI input ports per sampler channel (and
716 added various new C++ methods for this new feature / design change, old
717 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
718 as deprecated but are still there and should provide full behavior
719 backward compatibility).
720 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
721 unsafe and caused compilation error with clang 2.x).
722 - Bugfix: only process the latest MIDI program change event.
723 - Introducing the LSCP shell, which provides convenient control of the
724 sampler from the command line by providing LSCP aware features.
725 - VirtualMidiDevice: Added support for program change.
726 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
727 - VirtualMidiDevice: Added support for pitch bend.
728 - Aftertouch: extended API to explicitly handle channel pressure and
729 polyphonic key pressure events (so far polyphonic pressure was not
730 supported at all, and channel pressure was rerouted as CC128 but not
731 used so far).
732 - Added initial support for real-time instrument scripts. The script VM
733 code is shared by all sampler engine implemementations, however only the
734 gig file format currently provides support for storing instrument scripts
735 (as LinuxSampler extension to the original GigaStudio 4 format).
736
737 * Gigasampler format engine:
738 - implemented the "round robin keyboard" dimension
739 - fixed round robin and random dimensions for cases when number of
740 dimension zones is not a power of two

742 key
743 - bugfix: pitch LFO controller "internal+aftertouch" was broken
744 - bugfix: filter keyboard tracking was broken
745 - filter performance fix (an unnecessary copy was made of the
746 filter parameters in each sub fragment)
747 - handle special case when pan parameter in gig file has max or
748 min value
749 - Exclusive Groups: don't ever stop voices of the same note,
750 doesn't sound naturally with a drumkit
751 - fixed EG1 modulation when attack or release is zero
752 - Fixed support for 'aftertouch' attenuation controller.
753 - Fixed crash that happened with velocity split sounds under certain
754 conditions (see also previous commit on libgig).
755 - fixed behaviour of filter LFO
756
757 * SFZ format engine:

787 - added support for loop_mode=one_shot
788 - fixed playback of 16 bit wav files on big endian CPUs
789 - added support for Ogg Vorbis sample files
790 - use loop markers from sample file if loop_start and loop_end are
791 not set in sfz file
792 - implemeted filters. Filter types: lowpass, bandpass, bandreject
793 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
794 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
795 cutoff_cc, cutoff_chanaft.
796 - bugfix: zero ampeg_sustain didn't work

985 the driver will automatically connect to other CoreMIDI clients' ports
986 (e.g. external MIDI devices being attached to the Mac)
987 - added support for MIDI note on velocity filter
988 - CoreMIDI: fixed memory deallocation error
989 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
990 virtual keyboards in frontends / instrument editors being stuck.

1159 crashes and noise on such transitions).
1160 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1161 (fixes #208)
1162 - Fixed bug in LSCP grammar definition which caused a statement like
1163 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1164 practically irrelevant, however it caused problems with the new LSCP
1165 shell's auto completion feature).
1166 - Fixed MIDI program change messages being ignored if quickly executed
1167 after each other (fixes #231).
1168
1169 Version 1.0.0 (31 July 2009)
1170
1171 * packaging changes:
1172 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1184 directory of liblinuxsampler dll (look in the same directory and one
1185 directory above)
1186 - configure script fix: removed unconditional use of SSE
1187 - fixed building with sqlite installed in a non-standard directory
1188 - when cross-compiling, don't try to create instruments.db
1189 - fix for new mingw-w64 version, which has usleep
1190
1191 * general changes:
1192 - bugfix: on some POSIX systems instrument editor plugins refused to
1193 load as we used a non-portable Linux specific struct field
1194 (fixes bug #70, patch by Ronald Baljeu)
1195 - fixed endless loop which occured when loading an instrument editor
1196 plugin DLL on Windows systems failed
1197 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1198 - optimized the SynchronizedConfig class so it doesn't wait
1199 unnecessarily long after an update

1201 events (e.g. to highlight the pressed keys on the virtual keyboard
1202 of gigedit)
1203 - added support for triggering notes by instrument editors (see above)
1204 - be verbose on DLL load errors (on Linux)
1205 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1207 implementation, which is usually faster)
1208 - fixes for audio drivers with varying buffer sizes
1209 - experimental support for running LinuxSampler as a DSSI, LV2 and
1210 VST plugin
1211 - notification events for stream/voice count statistics are now sent

1216 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1217 - automatic stacktrace mechanism is now turned off by default and can
1218 be switched on by command line option "--stacktrace" (the automatic
1219 stacktrace mechanism seems to be broken on most systems at the moment)
1220 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1221 a pointer to the launched InstrumentEditor object
1222 - added optional 3rd party user data parameter for following
1223 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1224 InstrumentEditor::Launch(),

1226 - theoretical fix: made SynchronizedConfig follow C++0x memory
1227 model more strictly
1228 - fixes for using large audio device buffers
1229 - Windows: add the installation directory to the DLL search path
1230 when loading an editor plugin (solves problems with VST and

1233
1234 * audio driver:
1235 - removed the nonsense audio channel constraint (which was hard coded to
1236 max. 100 audio channels) for most audio drivers
1237 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1238 opposed to the LSCP specs
1239 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1240 reflected the wrong value
1241 - fixed a memory management bug in ASIO driver
1242 - Makefile fix: JACK_CFLAGS wasn't used
1243 - JACK: use jack_client_open instead of the deprecated

1250 win64)
1251 - VST: added support for sample rate and buffer size changes
1252 - VST: close editor (Fantasia) when the VST is removed
1253 - VST: avoid opening Fantasia more than once for each VST instance
1254 - VST: export main function as "main" on Linux too (fix for
1255 energyXT)
1256 - VST: changed number of output channels from one stereo to 16
1257 stereo
1258 - added channel routing, fxsends and midi maps to the settings
1259 stored in the plugin state
1260 - performance optimization of AudioChannel::MixTo() and
1261 AudioChannel::CopyTo() methods using GCC vector exensions
1262 (if available)
1263 - ASIO fixes: avoid initializing the device twice, avoid throwing
1264 exception when getting parameters from a disconnected device
1265
1266 * MIDI driver:
1267 - added JACK MIDI driver
1268 - dispatch bank select as ordinary CC as well, the user might seriously
1269 want to (mis)use it for some purpose ("fixed" in all current MIDI
1270 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1271 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1272 CoreMidi or AU
1273 - fixed mingw-w64 compilation error in MME driver
1274 - made program change handling in MIDI thread real-time safe by
1275 moving the logic to a non-RT thread
1276 - fixed minor memory leak in ALSA driver
1277
1278 * instruments database:
1279 - avoid time consuming samples scanning when adding instruments
1280 to the instruments database
1281 - added support for handling lost files in the instruments database
1282 - Implemented option for adding instruments in separate directories
1283 in the instruments database
1284 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1285 - work-around for missing fnmatch function on Windows to make
1286 instrument database compilable
1287 - added instrument database support on Windows
1288 works with both standalone mode and VST plugin.
1289 the instruments DB file is located in
1290 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1291 databases for each windows user
1292 if no DB is present it automatically creates the .linuxsampler subdir
1293 and then creates an empty DB
1294 - fixed recursive import, which was broken on Windows
1295
1296 * Gigasampler format engine:
1297 - fixed a memory leak that could happen when a channel was deleted
1298 while notes were playing
1299 - made it possible to load an instrument even if the audio thread
1300 isn't running
1301 - added partial support for the "Controller Triggered" MIDI rule,
1302 enough for piano gigs with pedal noise samples
1303 - minor fix: only mark FX sends as being modified if really the
1304 respective FX send MIDI controller was used
1305 - added support for GM global device volume SysEx message
1306 (can be selected at compile time to either apply globally to the
1307 whole sampler [default] or only to the sampler channels that are
1308 connected to the respective MIDI input port the SysEx message arrived
1309 on)
1310 - bugfix: notes triggered at position 0 in the audio buffer were
1311 sometimes wrongly killed in the same buffer, causing no sound to
1312 be played
1313 - added support for chromatic / drumkit mode Roland GS Sysex message
1314 which is usally used to switch a part between chromatic sounds and
1315 drumkit sounds (as opposed to their common default setting of MIDI
1316 part 10 being a drumkit part and all other ones chromatic parts), in
1317 LS however one can switch between the first 16 MIDI instrument maps
1318 defined for the sampler
1319 - made it possible to create multiple sample channels even if the
1320 audio thread isn't running
1321 - fixed crash when removing channel with active voices (#116)
1322 - bugfix: on sample reference changes (instrument editor), only
1323 un-cache the respective sample if it's really not used by any
1324 sampler engine anymore
1325 - re-cache samples in case they were changed by an instrument editor,
1326 e.g. when a sample was added while playing (#82)
1327 - fixed hanging notes which occured when note-off event had the exact
1328 same time stamp as the voice's note-on event and occured both in the
1329 same audio fragment cycle (fixes bug #112)
1330 - added support for the "fine tune" and "pitch bend range"
1331 instrument-level gig parameters
1332 - fixed minor artifacts in pitch bend handling
1333 - added support for GS Reset SysEx message
1334 - allow gig files to use unlimited downward pitch shifting
1335 - added a limit check for upward pitch shifting
1336 - bugfix: sometimes, when playing a note twice fast, the second
1337 note was silent
1338 - fixed crash happening when a pitch bend event arrived at the
1339 same time a new instrument was loading
1340
1341 * LSCP server:
1342 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1343 react on MIDI data arriving on certain sampler channels (so far only
1344 Note-On and Note-Off events are sent via this LSCP event)
1345 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1346 react on MIDI data arriving on certain MIDI input devices (so far only
1347 Note-On and Note-Off events are sent via this LSCP event)
1348 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1349 SET DB_INSTRUMENT FILE_PATH
1350 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1351 frontends to send MIDI messages to specific sampler channel
1352 - added two additional fields to GET FILE INSTRUMENT INFO command -
1353 KEY_BINDINGS and KEYSWITCH_BINDINGS
1354 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1355 was incorrect
1356 - Optimized the retrieval of the MIDI instrument mappings
1357 - added new LSCP command "SET VOICES" to globally alter the maximum
1358 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1359 be triggered respectively
1360 - added new LSCP command "SET STREAMS" to globally alter the maximum
1361 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1362 which will be triggered respectively
1363 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1364 a gigedit file dialog is opened)
1365 - close all connections when LSCPServer is deleted
1366 - hard close of all sockets on exit
1367 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1368 driver
1369
1370 * Bug fixes:
1371 - fixed a crash which occurs when removing a sampler channel waiting
1372 to start instrument loading after another channel
1373 - fixed a crash which occurs when removing a sampler channel with
1374 instrument loading in progress (bug #113)
1375 - fixed termination caused by uncaught exception when adding MIDI
1376 instrument with PERSISTENT load mode
1377 - fixed possible iterator invalidations when resetting the sampler
1378 - fixed memory leaks when issuing the following LSCP commands:
1379 GET AUDIO_OUTPUT_DRIVER INFO
1380 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1381 GET MIDI_INPUT_DRIVER INFO
1382 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1383 - fixed possible compilation error when sqlite is not present
1384 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1385 - fixed crash when changing the audio output device of a sampler
1386 channel with loaded instrument and start playing notes
1387 - fixed endless loop in Engine::SuspendAll() (bug #120)
1388 - fixed a low-level atomic load function that was broken on 64-bit
1389 PowerPC, which probably could cause crashes on that platform
1390 - fixed a memory management error which could cause a crash when a
1391 plugin was unloaded
1392 - bugfix: two private structs had the same name, which could cause
1393 problems if the linker chose the wrong constructor
1394 - fixed low-level ConditionServer usage bug that caused lockups on
1395 Windows
1396
1397
1398 Version 0.5.1 (6 December 2007)
1399
1400 * packaging changes:
1401 - added autoconf checks for pthread library
1402 - added autoconf check for pthread bug found on certain NPTL-enabled
1403 glibc versions (see Gentoo bug report #194076)
1404 - added autoconf checks for MS Windows
1405
1406 * general changes:
1407 - bugfix: the thread used by an editor plugin didn't die when the
1408 editor closed
1409 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1410 out all the space. operator--() did not apply size_mask after
1411 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1412 order to avoid problems with the _NonVolatileReader functions.
1413 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1414 GetWriteSpace(). Since this function is currently only used in
1415 the stream's qsort() compare function, it didn't trigger any
1416 bugs.
1417 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1418 24bit mode too. Faster method to read 24bit words on little
1419 endian machines (x86): replaced 3 byte reads + shifts with a 1
1420 unaligned 32bit read and shift
1421 - experimental support for MS Windows (MIDI input via MME, AUDIO
1422 output via ASIO)
1423 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1424 - support for monitoring the total number of active disk streams
1425 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1426 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1427
1428 * AUDIO driver:
1429 - added Windows ASIO low latency audio driver
1430
1431 * MIDI driver:
1432 - added MME Windows MIDI driver
1433
1434 * LSCP server:
1435 - added support for Windows style path / filenames, however with
1436 forward slash path separators instead of backslash
1437 (i.e. "C:/foo/bar.gig")
1438 - allow naughty liblscp to send non-string device parameters within
1439 apostrophes as well
1440 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1441 "LIST FILE INSTRUMENTS <file>" and
1442 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1443 about an arbitrary instrument file on the system where the sampler is
1444 running on
1445
1446 Version 0.5.0 (15 October 2007)
1447
1448 * packaging changes:
1449 - config.h is not going to be installed along with liblinuxsampler's
1450 API header files anymore
1451 - only the API relevant header (and source) files will be exported to
1452 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1453 - added completely new XCode project files for Mac OSX which is now
1454 capable to execute our autoconf environment, thus no need anymore
1455 to maintain the compile time configuration file (osx/version.h) for
1456 OSX manually (patch by Toshi Nagata)
1457 - fixed buggy boolean --enable-foo / --disable-foo configure script
1458 parameters
1459 - global.h now only covers global definitions that are needed for the
1460 C++ API header files, all implementation internal global definitions
1461 are now in global_private.h
1462 - atomic.h is not exposed to the C++ API anymore
1463 - no need to include config.h anymore for using LS's API header files
1464 - fixed warnings in API doc generation
1465
1466 * general changes:
1467 - replaced the old, confusing MIDI program change mechanism by a
1468 flexible MIDI instrument mapper which allows to map arbitrary
1469 (MIDI bank, MIDI program) pairs with arbitrary
1470 (engine type, instrument file, file index) triplets which will be
1471 loaded on the respective channel when such MIDI program change
1472 messages arrive, beside that, each entry allows to define a life-time
1473 strategy for the instrument, so the user can define whether the
1474 instrument should i.e. be permanently loaded (to be able to switch
1475 quickly among sounds) or i.e. loaded just on demand when the
1476 respective program change arrives (to safe RAM space), as well as a
1477 global volume factor for each entry, so the user can adjust the volume
1478 dynamic of his mapped instrument collection without having to modify
1479 the instrument files, also one can manage arbitrary amount of such
1480 MIDI instrument maps and assign each sampler channel individually
1481 a certain map, so that i.e. separation of normal instruments and
1482 drumkits is possible
1483 - new notification events for tracking changes to audio/MIDI devices,
1484 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1485 - sampler was limited to load max. 200 instruments in the background
1486 due to a constant size RingBuffer FIFO which is now replaced by a
1487 dynamic (unlimited) size std::list FIFO
1488 - added FX sends, these allow to route audio signals to arbitrary audio
1489 output channels for being processed by external effect processors
1490 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1491 controllers
1492 - global (sampler wide) volume can now be controlled at runtime
1493 - Implemented new, improved notification system
1494 - fixed compilation errors regarding OSX
1495 (patch by Toshi Nagata)
1496 - implemented instruments database
1497 - added support for escape sequences to the instruments database
1498 - added highly experimental support for on-the-fly instrument editing
1499 within the sampler's process (by using instrument editor plugins),
1500 you'll notice the new "Registered instrument editors:" message on
1501 startup, added a new LSCP command:
1502 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1503 to spawn a matching instrument editor for the instrument on the
1504 given sampler channel, the plugin path can be overridden at compile
1505 time with ./configure --enable-plugin-dir=/some/dir
1506 - added experimental code for synchronizing instrument editors hosted
1507 in the sampler's process to safely edit instruments while playing
1508 without a crash (hopefully) by either suspending single regions
1509 wherever possible or if unavoidable whole engine(s)
1510 - fixed several issues in fundamental "Thread" class: set scheduling
1511 policy and priority on thread level, set a minimum stack size for
1512 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1513 threads simply inherited properties of starting thread instead of
1514 setting their own policy and priority
1515 - minor fix in our automatic stack trace mechanism on crashes, the
1516 main process did not wait for the stack trace process to finish
1517 its output
1518 - fixed some minor memory leaks
1519 - reenabled assembly features support, at the moment only for
1520 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1521 - minor assembly fix in x86 features detection (don't use the PIC
1522 register, to avoid relocations in the text segment at runtime)
1523 - POSIX callback functions of Thread.h are hidden
1524
1525 * MIDI driver:
1526 - dispatch bank select (MSB and LSB) messages
1527
1528 * audio driver:
1529 - the ALSA audio output driver parameters now reflect the correct
1530 parameter value ranges for the respective selected sound card
1531 (patch by Till Wimmer, a bit fixed and extended)
1532
1533 * Gigasampler format engine:
1534 - if a filter is used and EG2 finishes before EG1, let the voice
1535 die when EG2 has finished (this fixes a problem with clicks and
1536 voice starvation for some gigs)
1537 - playback is no longer disabled during instrument loading
1538 - all notes playing on a channel that changes its instrument keep
1539 playing with the old instrument until they get a note off
1540 command
1541 - EG fix: a release value of zero could cause noises or crash
1542 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1543 - EG fine tuning: when attack is zero the EG starts at a level
1544 above max sustain level, which means that there is a decay phase
1545 even if sustain is 100%
1546 - more EG fixes: the level could sometimes go below zero and cause
1547 noises or crashes
1548 - minor fix of EGDecay (patch by Toshi Nagata)
1549 - fixed compiler error when --enable-override-filter-type was
1550 supplied to the configure script (fixes #46)
1551 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1552 instead of a fix value
1553 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1554 127 (solo mode) only kill voices if the respective mode really
1555 changed
1556
1557 * LSCP server:
1558 - fixed compile time error for old Bison versions
1559 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1560 - parser now supports extended ASCII character set
1561 (up to ASCII code 255, i.e. includes now umlauts and accents)
1562 - filename arguments in LSCP commands now allow to use escape
1563 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1564 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1565 code value like \xf2) (fixes bug #24)
1566 - the following LSCP commands now also support escape sequences for at
1567 least one of their text-based parameters (i.e. name, description):
1568 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1569 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1570 "SET DB_INSTRUMENT_DIRECTORY NAME",
1571 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1572 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1573 "FIND DB_INSTRUMENT_DIRECTORIES"
1574 - returns verbose syntax errors (line and column where syntax error
1575 occured, the unexpected character and the actually expected, possible
1576 character(s), the latter only if less than 5 possibilities)
1577 - made sure that LSCP syntax is not affected by gigedit locale
1578 settings
1579 - bugfix regarding strings parameter lists: all comma separated lists
1580 of strings were treated as being one string containing commas
1581 (fixes #57)
1582
1583 * Bug fixes:
1584 - fixed crash occurring on certain LSCP scripts (Bug 39)
1585 - another thread safety fix for lscp "load engine" and "set
1586 channel audio output device"
1587 - fixed a crash which occurs when reassigning the same engine
1588 on a sampler channel with connected MIDI device
1589 - fixed a crash which occurs when changing the number of ports of a MIDI
1590 device connected to a sampler channel to number less then or equal
1591 to the index of the port to which the sampler channel is connected.
1592 - The previous bindings were not been disconnected when altering
1593 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1594 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1595 - The active stream/voice count statistic was incorrect.
1596 - notification events were not been sent for some sampler
1597 channel changes
1598 - added default min and max values to restrict the number of allowed
1599 audio output channels and MIDI input ports
1600 - the connection to the PCM interface is now closed when destroying
1601 an audio output device
1602 - files with slash in their path or filename could not be loaded
1603
1604 * test cases:
1605 - updated and fixed (haven't been touched in a while)
1606
1607 Version 0.4.0 (24 November 2006)
1608
1609 * packaging changes:
1610 - changed deprecated copyright attribute to license; added ldconfig
1611 to post-(un)install steps; added devel package for liblinuxsampler;
1612 to linuxsampler.spec (RPM)
1613 - install necessary development header files for allowing 3rd party
1614 applications to link against liblinuxsampler
1615 - liblinuxsampler's API documentation can be generated with 'make docs'
1616 (Doxygen required)
1617 - added benchmark to automatically detect the best triangle LFO
1618 implementation (currently either an integer math solution or a
1619 di-harmonic approximation), automatic detection can be overriden
1620 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1621 configure script argument though (mandatory for cross-compilation)
1622 - do not automatically pick optimized gcc flags if the user already
1623 provided some on his own (as CXXFLAGS)
1624 - added compile time option to disable processing of All-Notes-Off MIDI
1625 messages
1626 - added compile time options to allow disabling the various audio and
1627 MIDI drivers
1628 - fixed automatic GCC CPU switch detection on PPC
1629 (patch by Ebrahim Mayat)
1630
1631 * Gigasampler format engine:
1632 - extensive synthesis optimization
1633 (reimplementation of EGs and LFO(s), removed synthesis parameter
1634 prerendering and the synthesis parameter matrix in general, splitting
1635 each audio fragment into subfragments now where each subfragment uses
1636 constant pitch and filter coefficients. The volume coefficient is
1637 linearly interpolated inside a subfragment, unless
1638 --disable-interpolate-volume is set.)
1639 - fine tuning of the EG modulation parameters
1640 - improved filter cutoff calculation by adding support for the
1641 following gig parameters: Cutoff freq (used when no cutoff
1642 controller is defined), Control invert, Minimum cutoff, Velocity
1643 curve and Velocity range. The keyboard tracking now scales
1644 cutoff frequency instead of resonance.
1645 - added support for gig parameter Resonance.
1646 - fixed bug in sysex handling (patch by Juan Linietsky)
1647 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1648 which can be overridden with --enable-global-attenuation
1649 - EG fixes: made the length of "attack hold" stage more
1650 accurate. Release stage can now start before attack stage
1651 ends. Cancel release didn't work when sustain was zero. Attack
1652 time now has a minimal value to prevent clicks.
1653 - fixed pitch changes larger than one octave
1654 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1655 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1656 all modes can be altered via standard GM messages, that is CC5 for
1657 altering portamento time, CC65 for enabling / disabling portamento
1658 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1659 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1660 parameter) and crossfade
1661 - added support for the "attenuation controller threshold" gig
1662 parameter
1663 - added smoothing of volume changes caused by control change
1664 messages
1665 - sample loop parameters are now taken from the DimensionRegion
1666 instead of the wave chunk
1667 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1668 not equal to a power of two
1669 - reimplementation of the filter algorithm. The new filter is more
1670 accurate and supports all gig filter types, including bandreject
1671 and lowpass turbo.
1672 - real support for 24 bit samples - samples are not truncated to
1673 16 bits anymore
1674 - support for aftertouch (channel pressure, not polyphonic
1675 aftertouch)
1676 - LFO1 behaviour fixed (dampening from max volume instead of
1677 amplifying from 0)
1678
1679 * LSCP server:
1680 - fixed application exit on broken pipe error (fixes bug #20)
1681 - fixed the notification messages delay due to lack of
1682 network activity (fixes bug #26)
1683 - fixed parser bug which occured on space(s) within device parameters
1684 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1685
1686 * audio driver:
1687 - added aRts audio output driver (by no means RT safe)
1688
1689 * MIDI driver:
1690 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1691 messages several times instead of once
1692 - API extension for MIDI drivers which already supply exact time stamps
1693 for events (i.e. for offline rendering based MIDI drivers)
1694 - added checks for bad MIDI data
1695
1696 * linuxsampler application:
1697 - show available sampler engine types on startup
1698
1699 * general changes:
1700 - support for muting sampler channels and solo mode of the same, two new
1701 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1702 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1703 introduced for this, the behavior is the same like on a mixer console
1704 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1705 --enable-process-muted-channels which can be used to enable the
1706 processing of muted channels.
1707 - support for sostenuto pedal
1708 - support for monitoring the total number of active voices
1709 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1710 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1711 - fixed some memory management errors
1712 - fixed some concurrency problems that could lead to crashes when
1713 LSCP commands were executed
1714 - fixed crash when instrument loading failed previously on the same
1715 sampler channel (fixes bug #36)
1716
1717 Version 0.3.3 (15 July 2005)
1718
1719 * packaging changes:
1720 - fixed compilation with gcc 4.0
1721
1722 * Gigasampler format engine:
1723 - LFO preprocessing was performed even though the respective LFO was
1724 disabled by the instrument patch (minor efficiency fix)
1725 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1726 for volume ramp downs in the same fragment (needed for current voice
1727 stealing implementation) then simply inform the user with a warning
1728 about possible click sounds and reduce the volume ramp down
1729 appropriately instead of cancelling the audio device connection
1730
1731 Version 0.3.2 (24 June 2005)
1732
1733 * packaging changes:
1734 - updated autotools build files to compile on OS X
1735 (conditional compilation of CoreMIDI and MidiShare drivers)
1736 - hand-crafted assembly optimization code can be disabled with
1737 './configure --disable-asm' (definitely not recommended)
1738 - fixed 'make dist' rule to include all necessary files
1739 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1740 (due to 'dist-bzip2' automake option)
1741
1742 * Gigasampler format engine:
1743 - support for the gig parameters for "release velocity response" curves
1744 - fine tuning of the EGADSR envelope
1745 - volume of release triggered samples now depends on note-on velocity,
1746 note length and gig parameter "release trigger decay" instead of
1747 note-off velocity.
1748 - revised voice stealing
1749 (fixes crash and endless loop caused by voice stealing)
1750 - don't reset scale tuning on instrument or audio output device change
1751 - handle key group conflicts right at the beginning of each fragment
1752 instead of when the respective voice is actually launched
1753 (fixes undefined behavior if stolen voices belonged to a key group -
1754 this case was followed by a "killed voice survived" error message)
1755 - fixed minor issue with null/silence samples
1756 (those stole voices even though they don't need a voice at all which
1757 resulted in "voice stealing didn't work out" messages)
1758 - don't reset volume, pan, pitch and MIDI controller values on
1759 instrument or audio output device change
1760
1761 * LSCP server:
1762 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1763 - fixed LSCP event "CHANNEL_INFO" notification
1764 (e.g. did not notify on volume changes or MIDI program change events)
1765
1766 * linuxsampler application:
1767 - added command line parameters --lscp-addr and --lscp-port to override
1768 default IP address and port of LSCP server
1769
1770 Version 0.3.1 (24 May 2005)
1771
1772 * initial release
