* Fix compiler error with release tarball if no Bison installed
  (SVN version still requires Flex and Bison being installed).

* Bumped version (2.2.0.svn7).

1 Version SVN trunk (?)
3 * general changes:
4 - AbstractEngineChannel: fixed CCs not being forwarded to all
5 VirtualMIDIDevices.
6 - Fix compiler error with release tarball if no Bison installed
7 (SVN version still requires Flex and Bison being installed).
9 * Real-time instrument scripts:
10 - Fix: Do not share compiled instrument scripts among multiple engine
11 channels (sampler parts) as this can lead to crashes and would allow the
12 same global script variables to be accessible from multiple engine
13 channels which would not be the expected behaviour by instrument script
14 authors.
16 * GigaStudio/Gigasampler format engine:
17 - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
18 issues with .gig file.
19 - Use libgig's new method gig::File::GetSample() with method
20 gig::File::CountSamples() instead of now deprecated
21 gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
22 - Use libgig's new method gig::Instrument::GetRegionAt() with method
23 gig::Instrument:CountRegions() instead of now deprecated
24 gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
25 - Use libgig's gig::File::GetInstrument() method with method
26 gig::File::CountInstruments() instead of now deprecated
27 gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
29 * MIDI driver:
30 - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
31 in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
32 - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
34 Version 2.2.0 (9 May 2021)
36 * general changes:
37 - Fixed compiler error in Pool.h.
38 - Require C++14 compiler support.
39 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
40 for checking in configure for C++14 support (as mandatory
41 requirement) and automatically adds compiler argument if required
42 (e.g. -std=C++14).
43 - RTMath: Implemented floating point comparison methods
44 fEqual32(float,float) and fEqual64(double,double) which take the
45 expected floating point tolerances into account.
46 - Added public API C++ class "LFO", which is a cluster class encapsulating
47 all the sampler's LFO implementations to be used by 3rd party applications
48 (e.g. by Gigedit).
49 - Added int math square LFO implementation.
50 - Added int math saw LFO implementation.
51 - Added numeric complex nr sine LFO implementation.
52 - Marked class LFOTriangleDiHarmonic as deprecated
53 (will be removed in future).
54 - Added LFOAll.h which includes all LFO implementation's header files.
55 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
56 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
57 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
58 SquareLFO -> LFOSquarePulse and separated the latter to its own header
59 file).
60 - Renamed type LFOSigned -> LFOTriangleSigned.
61 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
62 - Using now cubic interpolation as resampling algorithm by default; and
63 linear interpolation is deprecated now.
64 - Event:Init(): memset() entire Event::Param union to zero instead of trying
65 to do that for its individual members; the latter became error prone due
66 to the union's growing complexity meanwhile.
67 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
68 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
69 methods and marked the old ones as deprecated; and likewise added new
70 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
71 methods and marked those old ones deprecated as well.
72 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
73 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
74 - Implemented support for compressed RPN/NRPN message sequences (that is to
75 allow processing MIDI data entry messages without always having to be
76 preceded strictly by RPN/NRPN parameter selection messages on each value
77 change).
78 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
79 decrement).
80 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
81 MSB=127 and LSB=127) and which is disabling subsequent data
82 entry/increment/decrement CC messages.
83 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
84 instrument editor.
85 - Fixed playing noise at the end of a disk stream under certain conditions.
86 - Fixed potential crash with high pitch at end of RAM playback.
87 - Added configure checks whether C++ compiler supports so called
88 'designated initializers'.
89 - Added global backtraceAsString() function for debugging purposes
90 (POSIX systems only, no Windows implementation yet).
91 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
92 nameOfCaller() and setNameOfCaller().
93 - configure: Always check for availability of pthread_testcancel() and use
94 it if so (previously it was only used if explicitly enabled by configure
95 option).
96 - Thread class: raise compiler warning if pthread_testcancel() is not
97 available, because it can lead to deadlocks.
98 - Mutex class: Implemented optional bug detection and deadlock debugging
99 features.
100 - Ref<> class is now thread safe (as lock-free and wait-free
101 implementation).
102 - Fixed compilation error with Bison >= 3.6.0.
103 - Fixed rare crash when switching between instruments that had instrument
104 scripts loaded.
105 - Allow EffectChain::InsertEffect() as alternative to
106 EffectChain::AppendEffect() (i.e. with index equal to current chain size).
107 - ConstCapacityArray class: Fixed bug in remove() method.
108 - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
109 real-time instrument script was loaded.
111 * Real-time instrument scripts:
112 - Added method ScriptVM::setExitResultEnabled() which allows to
113 explicitly enable the built-in exit() function to optionally accept
114 one function argument; the value of the passed exit() function
115 argument will then become available by calling
116 VMExecContext::exitResult() after script execution.
117 - 64 bit support for NKSP integer scripts variables (declare $foo).
118 - Variable names, function names and preprocessor condition names must start
119 with a regular character (a-z or A-Z); starting them with a digit or
120 underscore is not allowed.
121 - NKSP parser fix: equal comparison operator "=" and not equal comparison
122 operator "#" must only accept integer operands.
123 - NKSP language: Implemented support for standard units like Hertz, seconds,
124 Bel including support for metric unit prefixes; so one can now e.g.
125 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
126 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
127 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
128 - NKSP language: Introduced "final" operator "!" which is specifically
129 intended for synthesis parameter values to denote that the synthesis
130 parameter value is intended to be the "final" value for that synthesis
131 parameter that should explicitly be used by the engine and thus causing
132 the sampler engine to ignore all other modulation sources for the same
133 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
134 variable or formula with this new "!" operator the expression is marked as
135 being "final".
136 - NKSP script editor API: Added support for detecting standard unit tokens
137 and their potential metric prefix token.
138 - NKSP language: Added support for NKSP real number literals and
139 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
140 - NKSP language: Added support for NKSP real number (floating point) script
141 variables (declare ~foo).
142 - NKSP language: Added support for NKSP real number (floating point) array
143 script variables (declare ?foo[]).
144 - Built-in script function "message()" accepts now real number argument as
145 well.
146 - Added built-in script function "real_to_int()" and its short hand form
147 "int()" for casting from real number to integer in NKSP scripts.
148 - Added built-in script function "int_to_real()" and its short hand form
149 "real()" for casting from integer to real number in NKSP scripts.
150 - Allow built-in exit() function to potentially accept real number type
151 argument as well.
152 - Built-in script functions may have a different return type depending on
153 the arguments passed to the function.
154 - Built-in script function "abs()" optionally accepts and returns real
155 number.
156 - Built-in script functions "min()" and "max()" optionally accept real
157 number arguments and return real number as result in that case.
158 - NKSP VM API: Allow units and 'final'ness to be returned as result from
159 built-in functions (added methods VMFunction::returnUnitType() and
160 VMFunction::returnsFinal() for that purpose which must be implemented by
161 built-in function implementations).
162 - NKSP language: Allow metric unit prefixes of numeric scalar and array
163 variables to be changed freely at runtime (unlike unit types like Hz etc.
164 which are still sticky, parse-time features of variables which cannot be
165 changed at runtime for the intentional sake of determinism).
166 - NKSP language: 'final' values are prohibited for array variables for now
167 (attempt causes a parsers error).
168 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
169 conditions of runtime control structures like if(), while(), select()
170 (attempt causes a parser error).
171 - NKSP VM API: Allow built-in functions to perform their own, individual
172 parse time checks of arguments going to be passed to the function at
173 runtime (added method VMFunction::checkArgs() for that purpose).
174 - NKSP language: raise parser warning if only one operand of binary
175 operators (like logical 'or' comparison) contain a 'final' value (because
176 it would always yield in a 'final' result in such cases).
177 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
178 different metric unit prefixes, which will behave as expected (e.g.
179 result of expression '1000us < 2ms' is true).
180 - NKSP language: Allow adding values with different metric unit prefixes
181 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
182 - NKSP language: Allow subtracting values with different metric unit
183 prefixes (e.g. result of expression '1ms - 20us' is '980us').
184 - NKSP language: Allow multiplying with any metric unit prefixes
185 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
186 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
187 we don't have any considerable practical use for a term like '4s^2'
188 (hence any attempt multiplying two unit types still causes parser error).
189 - NKSP language: Allow dividing by any metric unit prefixes and allow
190 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
191 yields in unit free result '8'). So this is now a way to cast units away
192 e.g. for passing the result to other expressions, certain function calls
193 or variables which are not accepting any units (or that specific unit).
194 - NKSP language: integer arrays and real number arrays can now be converted
195 to strings (e.g. for dumping their content with message() calls for
196 script debugging purposes).
197 - NKSP language: expressions and variables with units are now correctly
198 casted to strings (e.g. with message() calls).
199 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
200 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
201 floating point tolerances into account.
202 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
203 VMScalarNumberExpr::evalCastReal().
204 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
205 'VMIntArrayExpr' and 'VMRealArrayExpr'.
206 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
207 unitFactor() (runtime) methods.
208 - Built-in function "exit()" supports now returning units and 'final'ness
209 for test cases.
210 - The following built-in functions support now units as well: "abs()",
211 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
212 "real_to_int()", "int()", "int_to_real()" and "real()".
213 - Built-in functions "array_equal()", "search()" and "sort()" support now
214 real number arrays (correctly) as well.
215 - Added individual parse time checks of arguments to be passed to built-in
216 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
217 "array_equal()" and "search()" specific for their individual purposes.
218 - NKSP VM refactoring: Renamed all methods, functions and classes matching
219 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
220 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
221 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
222 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
223 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
224 isScalarNumber() -> isNumber()).
225 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
226 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
227 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
228 as convenient methods for automatically converting values to expected
229 metric value basis.
230 - Built-in function "wait()" accepts now both integers and real numbers as
231 argument.
232 - NKSP VM API cleanup: Get rid of legacy method
233 VMFunction::argType(vmint iArg) which was already superseded by its new
234 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
235 - NKSP parser: if wrong argument type was passed to a built-in function and
236 that built-in function accepts more than one data type for the argument,
237 then show all supported data types as parser error message.
238 - Built-in function "play_note()" accepts now real numbers and seconds as
239 unit type as well for its 3rd and 4th function arguments.
240 - The following built-in functions accept now real numbers as well for their
241 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
242 "change_attack()", "change_decay()", "change_release()",
243 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
244 "change_cutoff_sustain()", "change_cutoff_release()",
245 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
246 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
247 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
248 - Fixed built-in function "change_play_pos()" not having accepted metric
249 prefixes at all.
250 - Fixed the following built-in functions having misinterpreted values given
251 with unit type (for their 2nd argument) as if they were relative values
252 (that is as if they were passed without a unit type): "change_attack()",
253 "change_decay()", "change_release()", "change_cutoff_attack()",
254 "change_cutoff_decay()", "change_cutoff_release()".
255 - Fixed the following built-in functions having applied completely wrong
256 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
257 respective EGs being their modulation sink assume uint data type with
258 value range 0..1000 instead of 0.0..1.0.
259 - Added individual parse-time checks of function arguments for the following
260 built-in functions: "play_note()", "note_off()", "set_event_mark()",
261 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
262 "change_decay()", "change_release()", "change_cutoff_attack()",
263 "change_cutoff_decay()", "change_cutoff_release()",
264 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
265 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
266 "change_pan_time()".
267 - Don't abort function call if unit type was used and at the same time
268 'final' operator was omitted for the primary value argument of the
269 following built-in functions: "change_cutoff()", "change_attack()",
270 "change_decay()", "change_release()", "change_cutoff_attack()",
271 "change_cutoff_decay()", "change_cutoff_release()",
272 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
273 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
274 "change_pan_time()", instead imply 'final'ness at runtime and raise an
275 appropriate parser warning at parse time.
276 - Added built-in real number functions "round()", "ceil()", "floor()",
277 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
278 "cos()", "tan()", "asin()", "acos()", "atan()".
279 - Added built-in script real number constant "~NI_MATH_PI".
280 - Added built-in script real number constant "~NI_MATH_E".
281 - NKSP language: Allow unary '+' operator.
282 - Added built-in script functions "msb()" and "lsb()".
283 - NKSP language: Added support for RPN event handler
284 ("on rpn ... end on" in instrument scripts).
285 - NKSP language: Added support for NRPN event handler
286 ("on nrpn ... end on" in instrument scripts).
287 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
288 may be read from the new RPN/NRPN script handlers to get the (N)RPN
289 parameter that had been changed and its new value.
290 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
291 which are identifying the new (N)RPN handlers as such at script runtime.
292 - Implemented built-in script function "set_rpn()".
293 - Implemented built-in script function "set_nrpn()".
294 - Fix: built-in functions returning an array type were broken and caused a
295 crash when the built-in function's (supposed to be array) result value was
296 used by the script VM.
297 - Removed upper value constraint for 2nd argument of built-in functions
298 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
299 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
300 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
301 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
302 the LFO frequency / resonance / cutoff frequency.
303 - Reduced code involved for parsing NKSP variable declarations by using 2
304 generalized grammar rules with optional components (i.e. optional value
305 assignment and optional variable qualifiers) instead of previous linear
306 combinations of grammar rules, which also fixes some edge case.
307 - NKSP language parser: track code block locations also by a) raw byte
308 position in NKSP source code string and b) length of that code block in
309 bytes (along to the already existing code block tracking by line/column);
310 and added appropriate new members to public C++ API classes like
311 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
312 - NKSP language: Added support for 'patch' variable qualifier (capture their
313 locations and allow replacement of their assignment expression via VM C++
314 API).
315 - Fixed incorrect EG times if standard measuring unit was passed to built-in
316 functions "change_attack()", "change_decay()" or "change_release()".
317 - Fixed intermediate function result values never having reflected any
318 standard measuring unit type.
319 - Fixed re-entrant issue with function calls which caused wrong result
320 values if the same function was called multiple times in a term
321 (specifically if metric prefixes were used).
322 - NKSP language: Just throw a warning, not an error if an array variable of
323 size zero was declared.
324 - NKSP language: Allow omitting explicit array size on array variable
325 declaration if combined with immediate value assignment
326 (e.g. declare %foo[] := ( 1, 2, 3 ) ).
327 - NKSP language: emit warning if an array variable was declared with bigger
328 array size than amount of initial values been assigned, and initialize the
329 missing array elements with zero in this case.
330 - Fixed built-in NKSP exit() function to behave as return statement.
331 - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
332 data type.
333 - NKSP VM: Fixed the "release" handler being executed too often under
334 certain situations if polyphonic data was passed from "note" handler to
335 "release" handler.
336 - Fixed memory leak in NKSP parser: string tokens were allocated as C
337 strings and never freed.
338 - Fixed incorrect polyphonic data transfer from wrong note handler to
339 release handler; which also fixes no release handler being executed
340 sometimes, and due to the latter it also fixes potential crashes as some
341 polyphonic script events were never released and the engine hence was
342 running out of free script events.
343 - Fixed crash when handling array results of built-in functions
344 (e.g. "num_elements(by_marks($MARK_1)").
345 - NKSP VM: Fixed dead note events not been removed from user's event groups
346 (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
347 and set_event_mark() after max. size of event group list was exhausted).
349 * test cases:
350 - Fixed compiler errors in test cases.
351 - Updated README for how to compile & run test cases.
352 - Updated test case
353 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
354 expected behaviour of the Mutex class implementation (recursive
355 mutex type).
356 - Added test cases for NKSP core language aspects and core built-in
357 functions.
358 - Fixed thread tests segfaulting on Linux.
359 - NKSP: Added real number test cases for built-in functions exit(),
360 int_to_real(), real(), real_to_int() and int(), as well as for the
361 plus, minus and negate language operators.
362 - Added massive amount of NKSP test cases for standard measuring units and
363 'final' operator usage cases.
364 - Added NKSP test cases for (floating point tolerance aware) real number
365 equalness / unequalness comparison.
366 - Added NKSP int array and real array tests for value assignment and
367 initialization of arrays.
368 - Added NKSP test cases for built-in functions "round()", "ceil()",
369 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
370 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
371 - Added NKSP test cases for unary '+' operator.
372 - Added NKSP test cases for core built-in variables.
373 - Added thorough NKSP test cases for variable declarations.
375 * GigaStudio/Gigasampler format engine:
376 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
377 behaviour for start_level_mid.
378 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
379 level (see discussion "GigaStudio LFO compatibility" on mailing list
380 from 2019-09-26 for details).
381 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
382 see discussion "GigaStudio LFO compatibility" on mailing list from
383 2019-09-26 for details).
384 - Format extension: Added support for different LFO wave forms (currently
385 either sine [default], triangle, saw or square).
386 - Format extension: Added support for LFO phase displacement (0��..360��).
387 - Format extension: Added support for flipping LFO polarity on LFO 3
388 (in the original gig format this was only available for LFO 1 and LFO 2).
389 - Format extension: Support for additional filter types:
390 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
391 bandreject 2-pole.
392 - Fixd potential crash with polynomial interpolator and max. pitch.
393 - If minimum cutoff is defined, remap cutoff controller CC values to really
394 span the entire possible cutoff range (and avoiding a dead controller
395 zone).
396 - Implemented support for loading instrument scripts with 'patch' variables
397 (by patching these script variables with potentially overridden ones by
398 gig Instrument).
400 * SFZ format engine:
401 - Fixed support for regions with loccN/hiccN conditions on more than one
402 MIDI controller.
403 - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
404 'xfin_lovel' (patch by Christian Czezatke).
406 * Benchmarks:
407 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
408 algorithm (since result of 2nd run was not accumulated).
409 - Added benchmark for saw wave (benchmarks/saw.cpp).
410 - Added benchmark for sine wave (benchmarks/sine.cpp).
411 - Added benchmark for square wave (benchmarks/square.cpp).
412 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
413 which are large enough on modern systems.
415 Version 2.1.1 (27 Jul 2019)
417 * Real-time instrument scripts:
418 - Fixed behavior of built-in NKSP functions change_sustain(),
419 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
420 and change_cutoff_release().
422 * general changes:
423 - Only play release trigger samples on sustain pedal up if this behaviour
424 was explicitly requested by the instrument (otherwise only on note-off).
425 - Fixed compiler warnings.
426 - Fixed compilation error when cross-compiling to Mac.
427 - FX Sends: Provide more useful error messages on routing problems
428 (see bug #169).
429 - LSCP doc: Be more clear describing the two distinct approaches
430 of using external vs. internal effects (see bug #169).
431 - "optional" class: Fixed comparison operators.
433 * Gigasampler/GigaStudio format engine:
434 - Format extension: If requested by instrument then don't play release
435 trigger sample on note-off events.
437 * SFZ format engine:
438 - Fixed memory leak when releasing samples
439 (fixes bug #307, patch by Jacek Roszkowski)
440 - Fixed potential crash when a sample is shared by more than one region
441 (fixes bug #308, patch by Jacek Roszkowski).
442 - Opcode 'sample': Added support for built-in sample '*silence'
443 (fixes bug #310, patch by Jacek Roszkowski).
445 Version 2.1.0 (25 Nov 2017)
447 * SFZ format engine:
448 - added support for <global>, <master> and #define (patch by Alby M)
449 - Removed code duplication in SFZ file loading code.
450 - Added support for sfz extension opcode 'script' which may be used to
451 load real-time instrument script file (NKSP script language).
452 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
453 - Fixed unintended volume fade-in of voices under certain conditions.
454 - sfz parser: allow missing space between header and opcode
456 * Gigasampler/GigaStudio format engine:
457 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
458 cutoff settings.
459 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
460 all if an up-pitch of more than 40 semi tones was requested (I don't
461 think there is any stock gig sound that requires this behavior to
462 resemble its original sound).
463 - Added support for controlling whether the individual EGADSR stages may
464 be aborted (as LinuxSampler extension to the original GigaStudio 4
465 format).
467 * general changes:
468 - fixed printf type errors (mostly in debug messages)
469 - use unique_ptr instead of auto_ptr when building with C++11
470 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
471 allowing to sort data efficiently in real-time safe manner.
472 - RTList class: added methods for moving/inserting elements to arbitrary
473 position within a list.
474 - RTList class: added method fromPtr() for creating an Iterator object from
475 a raw element pointer.
476 - Attempt to partly fix resetting engine channels vs. resetting engine, an
477 overall cleanup of the Reset*(), ConnectAudioDevice(),
478 DisconnectAudioDevice() API methods would still be desirable though,
479 because the current situation is still inconsistent and error prone.
480 - Active voices are now internally grouped to "Note" objects, instead of
481 being directly assigned to a keyboard key. This allows more fine graded
482 processing of voices, which is i.e. required for certain instrument
483 script features.
484 - Fix: Release trigger voices were not spawned on sustain pedal up
485 (CC #64) events.
486 - Fix: Release trigger voices can now also distinguish correctly between
487 note-off and sustain pedal up events.
488 - All engines: Increased ramp speed of volume smoother and pan smoother
489 (while slow rate of crossfade smoother is preserved) to allow quick
490 volume and pan changes by instrument scripts for instance.
491 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
492 properly and thus were ignored for certain uses.
493 - Added new C++ API method
494 VirtualMidiDevice::SendChannelPressureToSampler().
495 - windows, 32-bit: fixed potential crashes by making sure the stack in
496 sub threads is 16-byte aligned
497 - fixed numerous compiler warnings
498 - Fixed invalid (note-on) event ID being assigned to new Note objects.
499 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
500 fixes potential undefined behavior.
501 - Fixed Note object leak when triggering notes on keys which did not
502 have a valid sample mapped (fixes bug #252).
503 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
504 - linuxsampler binary fix: option --create-instruments-db ignored
505 subsequent optional argument due to glibc's implementation oddity
506 which expects a "=" sign, but no space between them.
508 * packaging changes:
509 - removed unnecessary dependency to libuuid
510 (originated by libgig's usage of it)
511 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
512 auto detect whether it (sh/c)ould output its messages in color.
513 - Debian: Fixed packaging error about invalid "Source-Version"
514 substitution variable.
515 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
516 - Debian: Added build dependency to libsqlite3-dev for building
517 linuxsampler with instruments DB support.
519 * Real-time instrument scripts:
520 - Implemented scheduler for delayed MIDI events and for suspended scripts.
521 - Built-in script function "wait()": implemented support for function's
522 "duration-us" argument, thus scripts using this function are now
523 correctly resumed after the requested amount of microseconds.
524 - Built-in script function "play_note()": implemented support for
525 function's "duration-us" argument, thus notes triggered with this
526 argument are now correctly released after the requested amount of
527 microseconds.
528 - Fix: script events were not cleared when engine channel was reset,
529 potentially causing undefined behavior.
530 - Fixed crash which happened when trying to reference an undeclared
531 variable.
532 - Built-in script function "play_note()": Added support for passing
533 special value -1 for "duration-us" argument, which will cause the
534 triggered note to be released once the original note was released.
535 - Instrument script classes now exported with the liblinuxsampler C++ API.
536 - Added new API method ScriptVM::syntaxHighlighting() which provides
537 a convenient syntax highlighting backend for external instrument
538 script editor applications.
539 - Added new C++ API class "ScriptVMFactory".
540 - Extended parser issues to provide not only first line and first
541 column, but also last line and last column of issue (thus marking
542 the precise span of the issue within the source code).
543 - Reload script automatically after being modified by an instrument
544 editor.
545 - NKSP language grammar correction: allow empty event handler bodies
546 like "on note end on".
547 - Implemented built-in script function "change_vol()".
548 - Implemented built-in script function "change_tune()".
549 - Implemented built-in script function "change_pan()".
550 - Implemented built-in script function "change_cutoff()".
551 - Implemented built-in script function "change_reso()".
552 - Implemented built-in script function "event_status()".
553 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
554 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
555 "event_status()" function.
556 - NKSP language: Added support for bitwise operators ".or.", ".and."
557 and ".not.".
558 - NKSP language scanner: Fixed IDs matching to require at least one
559 character (i.e. when matching function names or variable names).
560 - NKSP language scanner: disabled unusued rules.
561 - Fixed behavior of play_note() and note_off() functions which must
562 be distinguished engine internally from "real" MIDI note on/off
563 events in order to avoid misbehaviors like hanging notes.
564 - Implemented built-in script variable "$KSP_TIMER".
565 - Implemented built-in script variable "$NKSP_REAL_TIMER".
566 - Implemented built-in script variable "$NKSP_PERF_TIMER".
567 - Implemented built-in script variable "$ENGINE_UPTIME".
568 - Implemented built-in script function "inc()".
569 - Implemented built-in script function "dec()".
570 - NKSP language fix: division expressions were evaluated too often.
571 - NKSP language fix: string concatenation operator was right
572 associative instead of left (to right).
573 - NKSP language correction: allow empty statements in entire language
574 (i.e. "if end if").
575 - Implemented built-in script function "stop_wait()".
576 - Implemented built-in script variable "$NI_CALLBACK_ID".
577 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
578 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
579 - Added support for read-only built-in variables (respectively
580 handled by the script parser).
581 - Added built-in script constant "$NI_CB_TYPE_INIT".
582 - Added built-in script constant "$NI_CB_TYPE_NOTE".
583 - Added built-in script constant "$NI_CB_TYPE_RELEASE".

586 - Implemented built-in script function "change_attack()".
587 - Implemented built-in script function "change_decay()".
588 - Implemented built-in script function "change_release()".
589 - Fixed all change_*() built-in script functions to apply their
590 synthesis parameter changes immediately in case the respective note
591 was triggered at the same time, instead of scheduling the parameter
592 change, especially because it would cause some parameter types's
593 changes either to be ramped (i.e. change_vol()) or other types even
594 to have not effect at all (i.e. change_attack()).
595 - Implemented built-in script function "sh_left()".
596 - Implemented built-in script function "sh_right()".
597 - Implemented built-in script function "min()".
598 - Implemented built-in script function "max()".
599 - NKSP Fix: "init" event handler was not always executed when a script
600 was loaded.
601 - NKSP built-in wait() script function: abort script execution if
602 a negative or zero wait time was passed as argument (since this is
603 a common indication of a bug either of the script or even of the
604 engine, which could lead to RT instability or even worse).
605 - ScriptVM: Implemented automatic suspension of RT safety
606 threatening scripts.
607 - Provide more user friendly error messages on syntax errors.
608 - Fixed NKSP parser warning "Not a statement" when assigning an
609 initializer list to an array variable.

612 - Implemented built-in script function "change_amp_lfo_depth()".
613 - Implemented built-in script function "change_amp_lfo_freq()".
614 - Implemented built-in script function "change_pitch_lfo_depth()".
615 - Implemented built-in script function "change_pitch_lfo_freq()".
616 - Implemented built-in script function "change_vol_time()".
617 - Implemented built-in script function "change_tune_time()".
618 - Implemented built-in script function "fade_in()".
619 - Implemented built-in script function "fade_out()".
620 - Fixed acceptance of wrong data type of parameters passed to built-in
621 script functions "change_vol()", "change_tune()", "change_pan()",
622 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
623 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
624 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
625 - Added built-in script function "get_event_par()" and implemented some
626 of its possible parameter selections.
627 - Added built-in script function "set_event_par()" and implemented some
628 of its possible parameter selections.
629 - Fixed a bunch of scheduler time related bugs.
630 - Fixed polyphonic variables not being reset to zero after usage.
631 - Built-in "ignore_event()" function: argument is now optional, like with
632 built-in function "ignore_controller()".
633 - Implemented built-in script function "change_velo()".
634 - Implemented built-in script function "change_note()".
635 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
636 intuitive behavior if used in combination with "change_vol_time()" or
637 "change_tune_time()" respectively: now tuning/volume changes are only
638 assigned (without delay) immediately to a new note if the respective
639 timing function has not been called before, otherwise the volume/tuning
640 changes are automatically faded (before, only the event's time stamp was
641 relevant).
642 - Implemented built-in script function "array_equal()".
643 - Implemented built-in script function "search()".
644 - Implemented built-in script function "sort()".
645 - NKSP Fix: Never suspend "init" event handlers.
646 - Implemented built-in script function "same_region()" (currently only
647 available for gig format engine).
648 - Added built-in script constant "$NKSP_LINEAR".
649 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
650 - Implemented built-in script function "change_vol_curve()".
651 - Implemented built-in script function "change_tune_curve()".
652 - built-in "play_note()" function now supports a sample playback start
653 offset with argument 3, where special value -1 means to use the regular
654 sample offset as defined by the instrument file.
655 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
656 - Built-in variable $EVENT_NOTE is now a read-only variable.
657 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
658 - built-in "play_note()" function now accepts -2 for its fourth argument
659 (note duration) which means the life time of the note shall be sticked
660 to the requested note number of argument 1.
661 - Fix: built-in "play_note()" function now returns 0 as result value if
662 -1 was passed for its fourth argument (note duration) and the respective
663 parent note is already gone.
664 - Implemented built-in script function "change_play_pos()".
665 - NKSP language: Added support for user declared const array variables.
666 - NKSP language: Raise parser warning if array variable is accessed with
667 an index that exceeds the array's size.
668 - NKSP language fix: Unknown characters were not handled correctly.
669 - NKSP language: Added support for "synchronized .. end synchronized"
670 code blocks.
671 - Implemented built-in script function "abort()" which allows to abort
672 another script handler by passing its callback ID.
673 - Fixed potential memory access bug and potential undefined behavior of
674 "init" event handlers.
675 - Print a time stamp along to each call of built-in function "message()".
676 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
677 to retrieve all code blocks filtered out by the preprocessor.
678 - Added built-in script function "fork()".
679 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
680 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
681 - Fixed potential crash when accessing dynamic built-in array variables.
682 - Added built-in script function "callback_status()".
683 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
684 - Added built-in constant $CALLBACK_STATUS_QUEUE.
685 - Added built-in constant $CALLBACK_STATUS_RUNNING.
686 - Removed max. value limitation of built-in functions "change_attack()",
687 "change_decay()" and "change_release()" to i.e. allow passing 2000000
688 for doubling the respective time.
689 - NKSP script editor syntax highlighting API: Fixed app termination due
690 to a lexer start condition stack underrun.
691 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
692 USE_CODE_IF_NOT() preprocessor statements.
693 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
694 can be set to disable all subsequent built-in "message()" function calls
695 on preprocessor level.
696 - Implemented built-in script function "change_sustain()".
697 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
698 to avoid the editor app to crash on ill-formed text input.

705 - Added built-in script function "change_cutoff_lfo_depth()".
706 - Added built-in script function "change_cutoff_lfo_freq()".
708 * Instruments DB:
709 - Fixed memory access bug of general DB access code which lead to
710 undefined behavior.
711 - Cleanup of instruments DB file creation and opening code.
712 - The instrument DB path of linuxsampler's --create-instruments-db argument
713 is now optional, if it is missing, then a default location is used.
714 - Added support for scanning SFZ (.sfz) files.
715 - Added support for scanning Sound Font (.sf2) files.
716 - Fixed undefined DB transaction behavior.
718 Version 2.0.0 (15 July 2015)

721 - fixed building with newer MinGW-w64
722 - Mac OS X: support the new dir for Core Audio SDK
723 - Mac OS X: fixed building outside source directory
724 - made sure all source files for hostplugins are included when
725 doing "make dist"
726 - removed empty directories left from the cvs to svn migration
727 - fixed compilation with gcc 4.6.1
728 - another "make dist" fix, for the LV2 plugin
729 - made --enable-pthread-testcancel default on Mac OS X
730 - minor Makefile fix for building lscpparser when build and source
731 directories are separate
732 - Mac OS X: made it possible to specify plugin installation dir to
733 configure
734 - Mac OS X: Makefile fix for the install-strip target
735 - fixed compilation with gcc 4.7
736 - fixed configure script error with old autoconf versions
737 - lsatomic.h: use gcc provided atomic functions if building with
738 gcc 4.7 and C++11
739 - modernized configure script
740 - fixed linkage error when building with
741 LDFLAGS="-Wl,--no-undefined" (#190)
742 - fixed compilation with Clang 3.2
743 - removed usage of deprecated Automake variable INCLUDES
744 - fixed building with C++11
745 - build fix: ChangeFlagRelaxed.h was missing in makefile
746 - build fix: libsndfile compiler flags were missing in some
747 makefiles
748 - fix for building with bison 3.0 (#202)
749 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
750 on the process's main thread
751 - fixed build error on newer MinGW
752 - support building with older jack versions
753 - support building with spaces in vst sdk path
754 - enabled automake 'subdir-objects' option and moved external
755 source references (vst, au, asio) from makefiles to cpp files,
756 in order to get rid of warnings from automake 1.14
758 * general changes:
759 - Refactoring: moved the independent code from
760 the Gigasampler format engine to base classes
761 - command line option '--profile' is currently disabled, since the
762 respective profiling code is currently broken
763 - Introduced support for optional environment variable
764 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
765 where the sampler shall look for instrument editor plugins
766 (patch by Luis Garrido, slightly modified).
767 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
768 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
769 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
770 note (in this implementation of the sampler its simply hard routed to
771 the 1st effect send of the sampler channel, no matter what the actual
772 effect type is)
773 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
774 note (in this implementation of the sampler its simply hard routed to
775 the 2nd effect send of the sampler channel, no matter what the actual
776 effect type is)
777 - implemented support for internal LADSPA effects
778 - raised limit of program change queue from 100 to 512
779 (as suggested by Alex Stone)
780 - implemented sine LFO, pulse LFO and saw LFO
781 - experimental support for per voice equalization
782 - added command line option --exec-after-init
783 - Introduced new C++ API method:
784 EngineChannel::InstrumentFileName(int index)
785 allowing to retrieve the whole list of files used for the loaded
786 instrument on an engine channel (a.k.a. part). Some GigaStudio
787 instruments for example are splitted over several files like
788 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
789 - Added new C++ API method Sampler::GetGlobalMaxVoices().
790 - Added new C++ API method Sampler::GetGlobalMaxStreams().
791 - Added new C++ API method Sampler::SetGlobalMaxVoices().
792 - Added new C++ API method Sampler::SetGlobalMaxStreams().
793 - Various "const" and "restrict" optimizations.
794 - all engines: add pan CC value to instrument pan parameter before
795 applying panning, instead of using two separate pan functions in
796 series (#182)
797 - added a lock guard class for exception safe mutex handling and
798 used it everywhere appropriate
799 - Immediately apply scale tuning changes to active voices.
800 - Exposed scale tuning to C++ API (along to the already existing standard
801 SysEx way).
802 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
803 and broken for ppc64. (Seq_cst loads and stores are actually not
804 used in LS, so the bug wasn't noticable.)
805 - lsatomic.h: added ARMv7 support
806 - Added support for multiple MIDI input ports per sampler channel (and
807 added various new C++ methods for this new feature / design change, old
808 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
809 as deprecated but are still there and should provide full behavior
810 backward compatibility).
811 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
812 unsafe and caused compilation error with clang 2.x).
813 - Bugfix: only process the latest MIDI program change event.
814 - Introducing the LSCP shell, which provides convenient control of the
815 sampler from the command line by providing LSCP aware features.
816 - VirtualMidiDevice: Added support for program change.
817 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
818 - VirtualMidiDevice: Added support for pitch bend.
819 - Aftertouch: extended API to explicitly handle channel pressure and
820 polyphonic key pressure events (so far polyphonic pressure was not
821 supported at all, and channel pressure was rerouted as CC128 but not
822 used so far).
823 - Added initial support for real-time instrument scripts. The script VM
824 code is shared by all sampler engine implemementations, however only the
825 gig file format currently provides support for storing instrument scripts
826 (as LinuxSampler extension to the original GigaStudio 4 format).
828 * Gigasampler format engine:
829 - implemented the "round robin keyboard" dimension
830 - fixed round robin and random dimensions for cases when number of
831 dimension zones is not a power of two
832 - made round robin use a counter for each region instead of each
833 key
834 - bugfix: pitch LFO controller "internal+aftertouch" was broken
835 - bugfix: filter keyboard tracking was broken
836 - filter performance fix (an unnecessary copy was made of the
837 filter parameters in each sub fragment)
838 - handle special case when pan parameter in gig file has max or
839 min value
840 - Exclusive Groups: don't ever stop voices of the same note,
841 doesn't sound naturally with a drumkit
842 - fixed EG1 modulation when attack or release is zero
843 - Fixed support for 'aftertouch' attenuation controller.
844 - Fixed crash that happened with velocity split sounds under certain
845 conditions (see also previous commit on libgig).
846 - fixed behaviour of filter LFO
848 * SFZ format engine:
849 - Initial implementation (not usable yet)
850 - added support for v2 multiple stage envelope generators
851 - added a fine-tuned v1 envelope generator instead of using the
852 one from the gig engine
853 - fixed memory leak and memory handling errors
854 - added support for trigger=first, trigger=legato and sw_previous
855 - allow non-numerical key values ("C#4" for example)
856 - "key" opcode now sets pitch_keycenter too
857 - fixed error when unloading instrument with same sample used by
858 multiple regions
859 - added some opcode aliases, like loopmode for loop_mode, to be
860 more compatible
861 - added support for trigger=release and rt_decay
862 - added support for off_mode=normal
863 - added support for random, seq_position, seq_length and volume
864 - added v1 LFO opcodes to parser (no support in engine yet)
865 - added support for amp_veltrack and amp_velcurve_N
866 - fine-tuned the default velocity curve
867 - added support for transpose
868 - fixed crash when using sw_down/up
869 - improved logic for sw_lokey/hikey/up/down/last
870 - added more v1 aliases to parser
871 - reduced memory usage for sfz data
872 - RT-safeness: avoid malloc in audio thread
873 - fixed a bug that could cause voice stealing to fail
874 - optimized sample lookup
875 - improved support for exclusive groups (group, off_by and
876 off_mode)
877 - added support for controller triggered regions (on_locc/on_hicc)
878 - added support for loop_mode=one_shot
879 - fixed playback of 16 bit wav files on big endian CPUs
880 - added support for Ogg Vorbis sample files
881 - use loop markers from sample file if loop_start and loop_end are
882 not set in sfz file
883 - implemeted filters. Filter types: lowpass, bandpass, bandreject
884 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
885 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
886 cutoff_cc, cutoff_chanaft.
887 - bugfix: zero ampeg_sustain didn't work
888 - added support for velocity effect on amplifier envelope time
889 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

1075 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1076 the driver will automatically connect to other CoreMIDI clients' ports
1077 (e.g. external MIDI devices being attached to the Mac)
1078 - added support for MIDI note on velocity filter
1079 - CoreMIDI: fixed memory deallocation error
1080 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1254 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1255 practically irrelevant, however it caused problems with the new LSCP
1256 shell's auto completion feature).
1257 - Fixed MIDI program change messages being ignored if quickly executed
1258 after each other (fixes #231).
1260 Version 1.0.0 (31 July 2009)
1262 * packaging changes:

1293 of gigedit)
1294 - added support for triggering notes by instrument editors (see above)
1295 - be verbose on DLL load errors (on Linux)
1296 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1298 implementation, which is usually faster)
1299 - fixes for audio drivers with varying buffer sizes
1300 - experimental support for running LinuxSampler as a DSSI, LV2 and
1301 VST plugin
1302 - notification events for stream/voice count statistics are now sent
1303 only when there are actual changes
1304 - added memory ordering constraints to improve stability on
1305 multi-core and multi-cpu systems
1306 - maximum voices and disk streams can now be altered at runtime
1307 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1308 - automatic stacktrace mechanism is now turned off by default and can
1309 be switched on by command line option "--stacktrace" (the automatic
1310 stacktrace mechanism seems to be broken on most systems at the moment)
1311 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1312 a pointer to the launched InstrumentEditor object
1313 - added optional 3rd party user data parameter for following
1314 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1315 InstrumentEditor::Launch(),
1316 InstrumentManager::LaunchInstrumentEditor()
1317 - theoretical fix: made SynchronizedConfig follow C++0x memory
1318 model more strictly
1319 - fixes for using large audio device buffers
1320 - Windows: add the installation directory to the DLL search path
1321 when loading an editor plugin (solves problems with VST and
1322 gigedit on systems with other GTK versions installed)
1323 - updated linuxsampler man page
1325 * audio driver:
1326 - removed the nonsense audio channel constraint (which was hard coded to
1327 max. 100 audio channels) for most audio drivers
1328 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1329 opposed to the LSCP specs
1330 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1331 reflected the wrong value
1332 - fixed a memory management bug in ASIO driver
1333 - Makefile fix: JACK_CFLAGS wasn't used
1334 - JACK: use jack_client_open instead of the deprecated
1335 jack_client_new
1336 - added (experimental) CoreAudio driver
1337 - applied old fixes to the ASIO driver that were included in the
1338 previous binary release but accidentally never committed to CVS
1339 (fixes #117)
1340 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1341 win64)
1342 - VST: added support for sample rate and buffer size changes
1343 - VST: close editor (Fantasia) when the VST is removed
1344 - VST: avoid opening Fantasia more than once for each VST instance
1345 - VST: export main function as "main" on Linux too (fix for
1346 energyXT)
1347 - VST: changed number of output channels from one stereo to 16
1348 stereo
1349 - added channel routing, fxsends and midi maps to the settings
1350 stored in the plugin state
1351 - performance optimization of AudioChannel::MixTo() and
1352 AudioChannel::CopyTo() methods using GCC vector exensions
1353 (if available)
1354 - ASIO fixes: avoid initializing the device twice, avoid throwing
1355 exception when getting parameters from a disconnected device
1357 * MIDI driver:
1358 - added JACK MIDI driver
1359 - dispatch bank select as ordinary CC as well, the user might seriously
1360 want to (mis)use it for some purpose ("fixed" in all current MIDI
1361 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1362 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1363 CoreMidi or AU
1364 - fixed mingw-w64 compilation error in MME driver
1365 - made program change handling in MIDI thread real-time safe by
1366 moving the logic to a non-RT thread
1367 - fixed minor memory leak in ALSA driver
1369 * instruments database:
1370 - avoid time consuming samples scanning when adding instruments
1371 to the instruments database
1372 - added support for handling lost files in the instruments database
1373 - Implemented option for adding instruments in separate directories
1374 in the instruments database
1375 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1376 - work-around for missing fnmatch function on Windows to make
1377 instrument database compilable
1378 - added instrument database support on Windows
1379 works with both standalone mode and VST plugin.
1380 the instruments DB file is located in
1381 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1382 databases for each windows user
1383 if no DB is present it automatically creates the .linuxsampler subdir
1384 and then creates an empty DB
1385 - fixed recursive import, which was broken on Windows
1387 * Gigasampler format engine:
1388 - fixed a memory leak that could happen when a channel was deleted
1389 while notes were playing
1390 - made it possible to load an instrument even if the audio thread
1391 isn't running
1392 - added partial support for the "Controller Triggered" MIDI rule,
1393 enough for piano gigs with pedal noise samples
1394 - minor fix: only mark FX sends as being modified if really the
1395 respective FX send MIDI controller was used
1396 - added support for GM global device volume SysEx message
1397 (can be selected at compile time to either apply globally to the
1398 whole sampler [default] or only to the sampler channels that are
1399 connected to the respective MIDI input port the SysEx message arrived
1400 on)
1401 - bugfix: notes triggered at position 0 in the audio buffer were
1402 sometimes wrongly killed in the same buffer, causing no sound to
1403 be played
1404 - added support for chromatic / drumkit mode Roland GS Sysex message
1405 which is usally used to switch a part between chromatic sounds and
1406 drumkit sounds (as opposed to their common default setting of MIDI
1407 part 10 being a drumkit part and all other ones chromatic parts), in
1408 LS however one can switch between the first 16 MIDI instrument maps
1409 defined for the sampler
1410 - made it possible to create multiple sample channels even if the
1411 audio thread isn't running
1412 - fixed crash when removing channel with active voices (#116)
1413 - bugfix: on sample reference changes (instrument editor), only
1414 un-cache the respective sample if it's really not used by any
1415 sampler engine anymore
1416 - re-cache samples in case they were changed by an instrument editor,
1417 e.g. when a sample was added while playing (#82)
1418 - fixed hanging notes which occured when note-off event had the exact
1419 same time stamp as the voice's note-on event and occured both in the
1420 same audio fragment cycle (fixes bug #112)
1421 - added support for the "fine tune" and "pitch bend range"
1422 instrument-level gig parameters
1423 - fixed minor artifacts in pitch bend handling
1424 - added support for GS Reset SysEx message
1425 - allow gig files to use unlimited downward pitch shifting
1426 - added a limit check for upward pitch shifting
1427 - bugfix: sometimes, when playing a note twice fast, the second
1428 note was silent
1429 - fixed crash happening when a pitch bend event arrived at the
1430 same time a new instrument was loading
1432 * LSCP server:
1433 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1434 react on MIDI data arriving on certain sampler channels (so far only
1435 Note-On and Note-Off events are sent via this LSCP event)
1436 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1437 react on MIDI data arriving on certain MIDI input devices (so far only
1438 Note-On and Note-Off events are sent via this LSCP event)
1439 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1441 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1442 frontends to send MIDI messages to specific sampler channel
1443 - added two additional fields to GET FILE INSTRUMENT INFO command -
1445 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1446 was incorrect
1447 - Optimized the retrieval of the MIDI instrument mappings
1448 - added new LSCP command "SET VOICES" to globally alter the maximum
1449 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1450 be triggered respectively
1451 - added new LSCP command "SET STREAMS" to globally alter the maximum
1452 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1453 which will be triggered respectively
1454 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1455 a gigedit file dialog is opened)
1456 - close all connections when LSCPServer is deleted
1457 - hard close of all sockets on exit
1458 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1459 driver
1461 * Bug fixes:
1462 - fixed a crash which occurs when removing a sampler channel waiting
1463 to start instrument loading after another channel
1464 - fixed a crash which occurs when removing a sampler channel with
1465 instrument loading in progress (bug #113)
1466 - fixed termination caused by uncaught exception when adding MIDI
1467 instrument with PERSISTENT load mode
1468 - fixed possible iterator invalidations when resetting the sampler
1469 - fixed memory leaks when issuing the following LSCP commands:
1474 - fixed possible compilation error when sqlite is not present
1475 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1476 - fixed crash when changing the audio output device of a sampler
1477 channel with loaded instrument and start playing notes
1478 - fixed endless loop in Engine::SuspendAll() (bug #120)
1479 - fixed a low-level atomic load function that was broken on 64-bit
1480 PowerPC, which probably could cause crashes on that platform
1481 - fixed a memory management error which could cause a crash when a
1482 plugin was unloaded
1483 - bugfix: two private structs had the same name, which could cause
1484 problems if the linker chose the wrong constructor
1485 - fixed low-level ConditionServer usage bug that caused lockups on
1486 Windows
1489 Version 0.5.1 (6 December 2007)
1491 * packaging changes:
1492 - added autoconf checks for pthread library
1493 - added autoconf check for pthread bug found on certain NPTL-enabled
1494 glibc versions (see Gentoo bug report #194076)
1495 - added autoconf checks for MS Windows
1497 * general changes:
1498 - bugfix: the thread used by an editor plugin didn't die when the
1499 editor closed
1500 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1501 out all the space. operator--() did not apply size_mask after
1502 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1503 order to avoid problems with the _NonVolatileReader functions.
1504 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1505 GetWriteSpace(). Since this function is currently only used in
1506 the stream's qsort() compare function, it didn't trigger any
1507 bugs.
1508 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1509 24bit mode too. Faster method to read 24bit words on little
1510 endian machines (x86): replaced 3 byte reads + shifts with a 1
1511 unaligned 32bit read and shift
1512 - experimental support for MS Windows (MIDI input via MME, AUDIO
1513 output via ASIO)
1514 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1515 - support for monitoring the total number of active disk streams
1516 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1519 * AUDIO driver:
1520 - added Windows ASIO low latency audio driver
1522 * MIDI driver:
1523 - added MME Windows MIDI driver
1525 * LSCP server:
1526 - added support for Windows style path / filenames, however with
1527 forward slash path separators instead of backslash
1528 (i.e. "C:/foo/bar.gig")
1529 - allow naughty liblscp to send non-string device parameters within
1530 apostrophes as well
1531 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1532 "LIST FILE INSTRUMENTS <file>" and
1533 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1534 about an arbitrary instrument file on the system where the sampler is
1535 running on
1537 Version 0.5.0 (15 October 2007)
1539 * packaging changes:
1540 - config.h is not going to be installed along with liblinuxsampler's
1541 API header files anymore
1542 - only the API relevant header (and source) files will be exported to
1543 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1544 - added completely new XCode project files for Mac OSX which is now
1545 capable to execute our autoconf environment, thus no need anymore
1546 to maintain the compile time configuration file (osx/version.h) for
1547 OSX manually (patch by Toshi Nagata)
1548 - fixed buggy boolean --enable-foo / --disable-foo configure script
1549 parameters
1550 - global.h now only covers global definitions that are needed for the
1551 C++ API header files, all implementation internal global definitions
1552 are now in global_private.h
1553 - atomic.h is not exposed to the C++ API anymore
1554 - no need to include config.h anymore for using LS's API header files
1555 - fixed warnings in API doc generation
1557 * general changes:
1558 - replaced the old, confusing MIDI program change mechanism by a
1559 flexible MIDI instrument mapper which allows to map arbitrary
1560 (MIDI bank, MIDI program) pairs with arbitrary
1561 (engine type, instrument file, file index) triplets which will be
1562 loaded on the respective channel when such MIDI program change
1563 messages arrive, beside that, each entry allows to define a life-time
1564 strategy for the instrument, so the user can define whether the
1565 instrument should i.e. be permanently loaded (to be able to switch
1566 quickly among sounds) or i.e. loaded just on demand when the
1567 respective program change arrives (to safe RAM space), as well as a
1568 global volume factor for each entry, so the user can adjust the volume
1569 dynamic of his mapped instrument collection without having to modify
1570 the instrument files, also one can manage arbitrary amount of such
1571 MIDI instrument maps and assign each sampler channel individually
1572 a certain map, so that i.e. separation of normal instruments and
1573 drumkits is possible
1574 - new notification events for tracking changes to audio/MIDI devices,
1575 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1576 - sampler was limited to load max. 200 instruments in the background
1577 due to a constant size RingBuffer FIFO which is now replaced by a
1578 dynamic (unlimited) size std::list FIFO
1579 - added FX sends, these allow to route audio signals to arbitrary audio
1580 output channels for being processed by external effect processors
1581 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1582 controllers
1583 - global (sampler wide) volume can now be controlled at runtime
1584 - Implemented new, improved notification system
1585 - fixed compilation errors regarding OSX
1586 (patch by Toshi Nagata)
1587 - implemented instruments database
1588 - added support for escape sequences to the instruments database
1589 - added highly experimental support for on-the-fly instrument editing
1590 within the sampler's process (by using instrument editor plugins),
1591 you'll notice the new "Registered instrument editors:" message on
1592 startup, added a new LSCP command:
1593 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1594 to spawn a matching instrument editor for the instrument on the
1595 given sampler channel, the plugin path can be overridden at compile
1596 time with ./configure --enable-plugin-dir=/some/dir
1597 - added experimental code for synchronizing instrument editors hosted
1598 in the sampler's process to safely edit instruments while playing
1599 without a crash (hopefully) by either suspending single regions
1600 wherever possible or if unavoidable whole engine(s)
1601 - fixed several issues in fundamental "Thread" class: set scheduling
1602 policy and priority on thread level, set a minimum stack size for
1603 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1604 threads simply inherited properties of starting thread instead of
1605 setting their own policy and priority
1606 - minor fix in our automatic stack trace mechanism on crashes, the
1607 main process did not wait for the stack trace process to finish
1608 its output
1609 - fixed some minor memory leaks
1610 - reenabled assembly features support, at the moment only for
1611 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1612 - minor assembly fix in x86 features detection (don't use the PIC
1613 register, to avoid relocations in the text segment at runtime)
1614 - POSIX callback functions of Thread.h are hidden
1616 * MIDI driver:
1617 - dispatch bank select (MSB and LSB) messages
1619 * audio driver:
1620 - the ALSA audio output driver parameters now reflect the correct
1621 parameter value ranges for the respective selected sound card
1622 (patch by Till Wimmer, a bit fixed and extended)
1624 * Gigasampler format engine:
1625 - if a filter is used and EG2 finishes before EG1, let the voice
1626 die when EG2 has finished (this fixes a problem with clicks and
1627 voice starvation for some gigs)
1628 - playback is no longer disabled during instrument loading
1629 - all notes playing on a channel that changes its instrument keep
1630 playing with the old instrument until they get a note off
1631 command
1632 - EG fix: a release value of zero could cause noises or crash
1633 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1634 - EG fine tuning: when attack is zero the EG starts at a level
1635 above max sustain level, which means that there is a decay phase
1636 even if sustain is 100%
1637 - more EG fixes: the level could sometimes go below zero and cause
1638 noises or crashes
1639 - minor fix of EGDecay (patch by Toshi Nagata)
1640 - fixed compiler error when --enable-override-filter-type was
1641 supplied to the configure script (fixes #46)
1642 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1643 instead of a fix value
1644 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1645 127 (solo mode) only kill voices if the respective mode really
1646 changed
1648 * LSCP server:
1649 - fixed compile time error for old Bison versions
1650 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1651 - parser now supports extended ASCII character set
1652 (up to ASCII code 255, i.e. includes now umlauts and accents)
1653 - filename arguments in LSCP commands now allow to use escape
1654 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1655 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1656 code value like \xf2) (fixes bug #24)
1657 - the following LSCP commands now also support escape sequences for at
1658 least one of their text-based parameters (i.e. name, description):
1665 - returns verbose syntax errors (line and column where syntax error
1666 occured, the unexpected character and the actually expected, possible
1667 character(s), the latter only if less than 5 possibilities)
1668 - made sure that LSCP syntax is not affected by gigedit locale
1669 settings
1670 - bugfix regarding strings parameter lists: all comma separated lists
1671 of strings were treated as being one string containing commas
1672 (fixes #57)
1674 * Bug fixes:
1675 - fixed crash occurring on certain LSCP scripts (Bug 39)
1676 - another thread safety fix for lscp "load engine" and "set
1677 channel audio output device"
1678 - fixed a crash which occurs when reassigning the same engine
1679 on a sampler channel with connected MIDI device
1680 - fixed a crash which occurs when changing the number of ports of a MIDI
1681 device connected to a sampler channel to number less then or equal
1682 to the index of the port to which the sampler channel is connected.
1683 - The previous bindings were not been disconnected when altering
1684 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1685 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1686 - The active stream/voice count statistic was incorrect.
1687 - notification events were not been sent for some sampler
1688 channel changes
1689 - added default min and max values to restrict the number of allowed
1690 audio output channels and MIDI input ports
1691 - the connection to the PCM interface is now closed when destroying
1692 an audio output device
1693 - files with slash in their path or filename could not be loaded
1695 * test cases:
1696 - updated and fixed (haven't been touched in a while)
1698 Version 0.4.0 (24 November 2006)
1700 * packaging changes:
1701 - changed deprecated copyright attribute to license; added ldconfig
1702 to post-(un)install steps; added devel package for liblinuxsampler;
1703 to linuxsampler.spec (RPM)
1704 - install necessary development header files for allowing 3rd party
1705 applications to link against liblinuxsampler
1706 - liblinuxsampler's API documentation can be generated with 'make docs'
1707 (Doxygen required)
1708 - added benchmark to automatically detect the best triangle LFO
1709 implementation (currently either an integer math solution or a
1710 di-harmonic approximation), automatic detection can be overriden
1711 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1712 configure script argument though (mandatory for cross-compilation)
1713 - do not automatically pick optimized gcc flags if the user already
1714 provided some on his own (as CXXFLAGS)
1715 - added compile time option to disable processing of All-Notes-Off MIDI
1716 messages
1717 - added compile time options to allow disabling the various audio and
1718 MIDI drivers
1719 - fixed automatic GCC CPU switch detection on PPC
1720 (patch by Ebrahim Mayat)
1722 * Gigasampler format engine:
1723 - extensive synthesis optimization
1724 (reimplementation of EGs and LFO(s), removed synthesis parameter
1725 prerendering and the synthesis parameter matrix in general, splitting
1726 each audio fragment into subfragments now where each subfragment uses
1727 constant pitch and filter coefficients. The volume coefficient is
1728 linearly interpolated inside a subfragment, unless
1729 --disable-interpolate-volume is set.)
1730 - fine tuning of the EG modulation parameters
1731 - improved filter cutoff calculation by adding support for the
1732 following gig parameters: Cutoff freq (used when no cutoff
1733 controller is defined), Control invert, Minimum cutoff, Velocity
1734 curve and Velocity range. The keyboard tracking now scales
1735 cutoff frequency instead of resonance.
1736 - added support for gig parameter Resonance.
1737 - fixed bug in sysex handling (patch by Juan Linietsky)
1738 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1739 which can be overridden with --enable-global-attenuation
1740 - EG fixes: made the length of "attack hold" stage more
1741 accurate. Release stage can now start before attack stage
1742 ends. Cancel release didn't work when sustain was zero. Attack
1743 time now has a minimal value to prevent clicks.
1744 - fixed pitch changes larger than one octave
1745 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1746 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1747 all modes can be altered via standard GM messages, that is CC5 for
1748 altering portamento time, CC65 for enabling / disabling portamento
1749 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1750 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1751 parameter) and crossfade
1752 - added support for the "attenuation controller threshold" gig
1753 parameter
1754 - added smoothing of volume changes caused by control change
1755 messages
1756 - sample loop parameters are now taken from the DimensionRegion
1757 instead of the wave chunk
1758 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1759 not equal to a power of two
1760 - reimplementation of the filter algorithm. The new filter is more
1761 accurate and supports all gig filter types, including bandreject
1762 and lowpass turbo.
1763 - real support for 24 bit samples - samples are not truncated to
1764 16 bits anymore
1765 - support for aftertouch (channel pressure, not polyphonic
1766 aftertouch)
1767 - LFO1 behaviour fixed (dampening from max volume instead of
1768 amplifying from 0)
1770 * LSCP server:
1771 - fixed application exit on broken pipe error (fixes bug #20)
1772 - fixed the notification messages delay due to lack of
1773 network activity (fixes bug #26)
1774 - fixed parser bug which occured on space(s) within device parameters
1777 * audio driver:
1778 - added aRts audio output driver (by no means RT safe)
1780 * MIDI driver:
1781 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1782 messages several times instead of once
1783 - API extension for MIDI drivers which already supply exact time stamps
1784 for events (i.e. for offline rendering based MIDI drivers)
1785 - added checks for bad MIDI data
1787 * linuxsampler application:
1788 - show available sampler engine types on startup
1790 * general changes:
1791 - support for muting sampler channels and solo mode of the same, two new
1792 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1793 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1794 introduced for this, the behavior is the same like on a mixer console
1795 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1796 --enable-process-muted-channels which can be used to enable the
1797 processing of muted channels.
1798 - support for sostenuto pedal
1799 - support for monitoring the total number of active voices
1802 - fixed some memory management errors
1803 - fixed some concurrency problems that could lead to crashes when
1804 LSCP commands were executed
1805 - fixed crash when instrument loading failed previously on the same
1806 sampler channel (fixes bug #36)
1808 Version 0.3.3 (15 July 2005)
1810 * packaging changes:
1811 - fixed compilation with gcc 4.0
1813 * Gigasampler format engine:
1814 - LFO preprocessing was performed even though the respective LFO was
1815 disabled by the instrument patch (minor efficiency fix)
1816 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1817 for volume ramp downs in the same fragment (needed for current voice
1818 stealing implementation) then simply inform the user with a warning
1819 about possible click sounds and reduce the volume ramp down
1820 appropriately instead of cancelling the audio device connection
1822 Version 0.3.2 (24 June 2005)
1824 * packaging changes:
1825 - updated autotools build files to compile on OS X
1826 (conditional compilation of CoreMIDI and MidiShare drivers)
1827 - hand-crafted assembly optimization code can be disabled with
1828 './configure --disable-asm' (definitely not recommended)
1829 - fixed 'make dist' rule to include all necessary files
1830 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1831 (due to 'dist-bzip2' automake option)
1833 * Gigasampler format engine:
1834 - support for the gig parameters for "release velocity response" curves
1835 - fine tuning of the EGADSR envelope
1836 - volume of release triggered samples now depends on note-on velocity,
1837 note length and gig parameter "release trigger decay" instead of
1838 note-off velocity.
1839 - revised voice stealing
1840 (fixes crash and endless loop caused by voice stealing)
1841 - don't reset scale tuning on instrument or audio output device change
1842 - handle key group conflicts right at the beginning of each fragment
1843 instead of when the respective voice is actually launched
1844 (fixes undefined behavior if stolen voices belonged to a key group -
1845 this case was followed by a "killed voice survived" error message)
1846 - fixed minor issue with null/silence samples
1847 (those stole voices even though they don't need a voice at all which
1848 resulted in "voice stealing didn't work out" messages)
1849 - don't reset volume, pan, pitch and MIDI controller values on
1850 instrument or audio output device change
1852 * LSCP server:
1853 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1854 - fixed LSCP event "CHANNEL_INFO" notification
1855 (e.g. did not notify on volume changes or MIDI program change events)
1857 * linuxsampler application:
1858 - added command line parameters --lscp-addr and --lscp-port to override
1859 default IP address and port of LSCP server
1861 Version 0.3.1 (24 May 2005)
1863 * initial release
