* Fix: Do not share compiled instrument scripts among multiple engine
  channels (sampler parts) as this can lead to crashes and would allow the
  same global script variables to be accessible from multiple engine
  channels which would not be the expected behaviour by instrument script

* Bumped version (2.2.0.svn5).

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

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

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

697 * Instruments DB:
698 - Fixed memory access bug of general DB access code which lead to
699 undefined behavior.
700 - Cleanup of instruments DB file creation and opening code.
701 - The instrument DB path of linuxsampler's --create-instruments-db argument
702 is now optional, if it is missing, then a default location is used.
703 - Added support for scanning SFZ (.sfz) files.
704 - Added support for scanning Sound Font (.sf2) files.
705 - Fixed undefined DB transaction behavior.
707 Version 2.0.0 (15 July 2015)

710 - fixed building with newer MinGW-w64
711 - Mac OS X: support the new dir for Core Audio SDK
712 - Mac OS X: fixed building outside source directory
713 - made sure all source files for hostplugins are included when
714 doing "make dist"
715 - removed empty directories left from the cvs to svn migration
716 - fixed compilation with gcc 4.6.1
717 - another "make dist" fix, for the LV2 plugin
718 - made --enable-pthread-testcancel default on Mac OS X
719 - minor Makefile fix for building lscpparser when build and source
720 directories are separate
721 - Mac OS X: made it possible to specify plugin installation dir to
722 configure
723 - Mac OS X: Makefile fix for the install-strip target
724 - fixed compilation with gcc 4.7
725 - fixed configure script error with old autoconf versions
726 - lsatomic.h: use gcc provided atomic functions if building with
727 gcc 4.7 and C++11
728 - modernized configure script
729 - fixed linkage error when building with
730 LDFLAGS="-Wl,--no-undefined" (#190)
731 - fixed compilation with Clang 3.2
732 - removed usage of deprecated Automake variable INCLUDES
733 - fixed building with C++11
734 - build fix: ChangeFlagRelaxed.h was missing in makefile
735 - build fix: libsndfile compiler flags were missing in some
736 makefiles
737 - fix for building with bison 3.0 (#202)
738 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
739 on the process's main thread
740 - fixed build error on newer MinGW
741 - support building with older jack versions
742 - support building with spaces in vst sdk path
743 - enabled automake 'subdir-objects' option and moved external
744 source references (vst, au, asio) from makefiles to cpp files,
745 in order to get rid of warnings from automake 1.14
747 * general changes:
748 - Refactoring: moved the independent code from
749 the Gigasampler format engine to base classes
750 - command line option '--profile' is currently disabled, since the
751 respective profiling code is currently broken
752 - Introduced support for optional environment variable
753 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
754 where the sampler shall look for instrument editor plugins
755 (patch by Luis Garrido, slightly modified).
756 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
757 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
758 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
759 note (in this implementation of the sampler its simply hard routed to
760 the 1st effect send of the sampler channel, no matter what the actual
761 effect type is)
762 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
763 note (in this implementation of the sampler its simply hard routed to
764 the 2nd effect send of the sampler channel, no matter what the actual
765 effect type is)
766 - implemented support for internal LADSPA effects
767 - raised limit of program change queue from 100 to 512
768 (as suggested by Alex Stone)
769 - implemented sine LFO, pulse LFO and saw LFO
770 - experimental support for per voice equalization
771 - added command line option --exec-after-init
772 - Introduced new C++ API method:
773 EngineChannel::InstrumentFileName(int index)
774 allowing to retrieve the whole list of files used for the loaded
775 instrument on an engine channel (a.k.a. part). Some GigaStudio
776 instruments for example are splitted over several files like
777 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
778 - Added new C++ API method Sampler::GetGlobalMaxVoices().
779 - Added new C++ API method Sampler::GetGlobalMaxStreams().
780 - Added new C++ API method Sampler::SetGlobalMaxVoices().
781 - Added new C++ API method Sampler::SetGlobalMaxStreams().
782 - Various "const" and "restrict" optimizations.
783 - all engines: add pan CC value to instrument pan parameter before
784 applying panning, instead of using two separate pan functions in
785 series (#182)
786 - added a lock guard class for exception safe mutex handling and
787 used it everywhere appropriate
788 - Immediately apply scale tuning changes to active voices.
789 - Exposed scale tuning to C++ API (along to the already existing standard
790 SysEx way).
791 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
792 and broken for ppc64. (Seq_cst loads and stores are actually not
793 used in LS, so the bug wasn't noticable.)
794 - lsatomic.h: added ARMv7 support
795 - Added support for multiple MIDI input ports per sampler channel (and
796 added various new C++ methods for this new feature / design change, old
797 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
798 as deprecated but are still there and should provide full behavior
799 backward compatibility).
800 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
801 unsafe and caused compilation error with clang 2.x).
802 - Bugfix: only process the latest MIDI program change event.
803 - Introducing the LSCP shell, which provides convenient control of the
804 sampler from the command line by providing LSCP aware features.
805 - VirtualMidiDevice: Added support for program change.
806 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
807 - VirtualMidiDevice: Added support for pitch bend.
808 - Aftertouch: extended API to explicitly handle channel pressure and
809 polyphonic key pressure events (so far polyphonic pressure was not
810 supported at all, and channel pressure was rerouted as CC128 but not
811 used so far).
812 - Added initial support for real-time instrument scripts. The script VM
813 code is shared by all sampler engine implemementations, however only the
814 gig file format currently provides support for storing instrument scripts
815 (as LinuxSampler extension to the original GigaStudio 4 format).
817 * Gigasampler format engine:
818 - implemented the "round robin keyboard" dimension
819 - fixed round robin and random dimensions for cases when number of
820 dimension zones is not a power of two
821 - made round robin use a counter for each region instead of each
822 key
823 - bugfix: pitch LFO controller "internal+aftertouch" was broken
824 - bugfix: filter keyboard tracking was broken
825 - filter performance fix (an unnecessary copy was made of the
826 filter parameters in each sub fragment)
827 - handle special case when pan parameter in gig file has max or
828 min value
829 - Exclusive Groups: don't ever stop voices of the same note,
830 doesn't sound naturally with a drumkit
831 - fixed EG1 modulation when attack or release is zero
832 - Fixed support for 'aftertouch' attenuation controller.
833 - Fixed crash that happened with velocity split sounds under certain
834 conditions (see also previous commit on libgig).
835 - fixed behaviour of filter LFO
837 * SFZ format engine:
838 - Initial implementation (not usable yet)
839 - added support for v2 multiple stage envelope generators
840 - added a fine-tuned v1 envelope generator instead of using the
841 one from the gig engine
842 - fixed memory leak and memory handling errors
843 - added support for trigger=first, trigger=legato and sw_previous
844 - allow non-numerical key values ("C#4" for example)
845 - "key" opcode now sets pitch_keycenter too
846 - fixed error when unloading instrument with same sample used by
847 multiple regions
848 - added some opcode aliases, like loopmode for loop_mode, to be
849 more compatible
850 - added support for trigger=release and rt_decay
851 - added support for off_mode=normal
852 - added support for random, seq_position, seq_length and volume
853 - added v1 LFO opcodes to parser (no support in engine yet)
854 - added support for amp_veltrack and amp_velcurve_N
855 - fine-tuned the default velocity curve
856 - added support for transpose
857 - fixed crash when using sw_down/up
858 - improved logic for sw_lokey/hikey/up/down/last
859 - added more v1 aliases to parser
860 - reduced memory usage for sfz data
861 - RT-safeness: avoid malloc in audio thread
862 - fixed a bug that could cause voice stealing to fail
863 - optimized sample lookup
864 - improved support for exclusive groups (group, off_by and
865 off_mode)
866 - added support for controller triggered regions (on_locc/on_hicc)
867 - added support for loop_mode=one_shot
868 - fixed playback of 16 bit wav files on big endian CPUs
869 - added support for Ogg Vorbis sample files
870 - use loop markers from sample file if loop_start and loop_end are
871 not set in sfz file
872 - implemeted filters. Filter types: lowpass, bandpass, bandreject
873 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
874 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
875 cutoff_cc, cutoff_chanaft.
876 - bugfix: zero ampeg_sustain didn't work
877 - added support for velocity effect on amplifier envelope time
878 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
879 ampeg_vel2release)
880 - added support for EG hold (ampeg_hold)
881 - added support for sample offset (offset)
882 - use the newly introduced signal units model
883 - implemented opcodes lfoN_delay,
884 lfoN_freq, lfoN_pan, lfoN_cutoff, lfoN_resonance

1016 incorrectly set to two. This caused silence in Cubase 5.
1017 - save engine type (gig, sfz or sf2) in plugin state
1018 - VST: when opening Fantasia, look for both 32 and 64 bit Java on

1064 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1065 the driver will automatically connect to other CoreMIDI clients' ports
1066 (e.g. external MIDI devices being attached to the Mac)
1067 - added support for MIDI note on velocity filter
1068 - CoreMIDI: fixed memory deallocation error
1069 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1243 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1244 practically irrelevant, however it caused problems with the new LSCP
1245 shell's auto completion feature).
1246 - Fixed MIDI program change messages being ignored if quickly executed
1247 after each other (fixes #231).
1249 Version 1.0.0 (31 July 2009)
1251 * packaging changes:

1274 (fixes bug #70, patch by Ronald Baljeu)
1275 - fixed endless loop which occured when loading an instrument editor
1276 plugin DLL on Windows systems failed
1277 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1278 - optimized the SynchronizedConfig class so it doesn't wait

1282 of gigedit)
1283 - added support for triggering notes by instrument editors (see above)
1284 - be verbose on DLL load errors (on Linux)
1285 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1287 implementation, which is usually faster)
1288 - fixes for audio drivers with varying buffer sizes
1289 - experimental support for running LinuxSampler as a DSSI, LV2 and
1290 VST plugin
1291 - notification events for stream/voice count statistics are now sent

1294 multi-core and multi-cpu systems
1295 - maximum voices and disk streams can now be altered at runtime
1296 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1297 - automatic stacktrace mechanism is now turned off by default and can
1298 be switched on by command line option "--stacktrace" (the automatic
1299 stacktrace mechanism seems to be broken on most systems at the moment)
1300 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1301 a pointer to the launched InstrumentEditor object
1302 - added optional 3rd party user data parameter for following
1303 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1304 InstrumentEditor::Launch(),
1305 InstrumentManager::LaunchInstrumentEditor()
1306 - theoretical fix: made SynchronizedConfig follow C++0x memory
1307 model more strictly
1308 - fixes for using large audio device buffers
1309 - Windows: add the installation directory to the DLL search path
1310 when loading an editor plugin (solves problems with VST and
1311 gigedit on systems with other GTK versions installed)
1312 - updated linuxsampler man page
1314 * audio driver:
1315 - removed the nonsense audio channel constraint (which was hard coded to
1316 max. 100 audio channels) for most audio drivers
1317 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1318 opposed to the LSCP specs
1319 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1320 reflected the wrong value
1321 - fixed a memory management bug in ASIO driver
1322 - Makefile fix: JACK_CFLAGS wasn't used
1323 - JACK: use jack_client_open instead of the deprecated
1324 jack_client_new
1325 - added (experimental) CoreAudio driver
1326 - applied old fixes to the ASIO driver that were included in the
1327 previous binary release but accidentally never committed to CVS
1328 (fixes #117)
1329 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1330 win64)
1331 - VST: added support for sample rate and buffer size changes
1332 - VST: close editor (Fantasia) when the VST is removed
1333 - VST: avoid opening Fantasia more than once for each VST instance
1334 - VST: export main function as "main" on Linux too (fix for
1335 energyXT)
1336 - VST: changed number of output channels from one stereo to 16
1337 stereo
1338 - added channel routing, fxsends and midi maps to the settings
1339 stored in the plugin state
1340 - performance optimization of AudioChannel::MixTo() and
1341 AudioChannel::CopyTo() methods using GCC vector exensions
1342 (if available)
1343 - ASIO fixes: avoid initializing the device twice, avoid throwing
1344 exception when getting parameters from a disconnected device
1346 * MIDI driver:
1347 - added JACK MIDI driver
1348 - dispatch bank select as ordinary CC as well, the user might seriously
1349 want to (mis)use it for some purpose ("fixed" in all current MIDI
1350 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1351 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1352 CoreMidi or AU
1353 - fixed mingw-w64 compilation error in MME driver
1354 - made program change handling in MIDI thread real-time safe by
1355 moving the logic to a non-RT thread
1356 - fixed minor memory leak in ALSA driver
1358 * instruments database:
1359 - avoid time consuming samples scanning when adding instruments
1360 to the instruments database
1361 - added support for handling lost files in the instruments database
1362 - Implemented option for adding instruments in separate directories
1363 in the instruments database
1364 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1365 - work-around for missing fnmatch function on Windows to make
1366 instrument database compilable
1367 - added instrument database support on Windows
1368 works with both standalone mode and VST plugin.
1369 the instruments DB file is located in
1370 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1371 databases for each windows user
1372 if no DB is present it automatically creates the .linuxsampler subdir
1373 and then creates an empty DB
1374 - fixed recursive import, which was broken on Windows
1376 * Gigasampler format engine:
1377 - fixed a memory leak that could happen when a channel was deleted
1378 while notes were playing
1379 - made it possible to load an instrument even if the audio thread
1380 isn't running
1381 - added partial support for the "Controller Triggered" MIDI rule,
1382 enough for piano gigs with pedal noise samples
1383 - minor fix: only mark FX sends as being modified if really the
1384 respective FX send MIDI controller was used
1385 - added support for GM global device volume SysEx message
1386 (can be selected at compile time to either apply globally to the
1387 whole sampler [default] or only to the sampler channels that are
1388 connected to the respective MIDI input port the SysEx message arrived
1389 on)
1390 - bugfix: notes triggered at position 0 in the audio buffer were
1391 sometimes wrongly killed in the same buffer, causing no sound to
1392 be played
1393 - added support for chromatic / drumkit mode Roland GS Sysex message
1394 which is usally used to switch a part between chromatic sounds and
1395 drumkit sounds (as opposed to their common default setting of MIDI
1396 part 10 being a drumkit part and all other ones chromatic parts), in
1397 LS however one can switch between the first 16 MIDI instrument maps
1398 defined for the sampler
1399 - made it possible to create multiple sample channels even if the
1400 audio thread isn't running
1401 - fixed crash when removing channel with active voices (#116)
1402 - bugfix: on sample reference changes (instrument editor), only
1403 un-cache the respective sample if it's really not used by any
1404 sampler engine anymore
1405 - re-cache samples in case they were changed by an instrument editor,
1406 e.g. when a sample was added while playing (#82)
1407 - fixed hanging notes which occured when note-off event had the exact
1408 same time stamp as the voice's note-on event and occured both in the
1409 same audio fragment cycle (fixes bug #112)
1410 - added support for the "fine tune" and "pitch bend range"
1411 instrument-level gig parameters
1412 - fixed minor artifacts in pitch bend handling
1413 - added support for GS Reset SysEx message
1414 - allow gig files to use unlimited downward pitch shifting
1415 - added a limit check for upward pitch shifting
1416 - bugfix: sometimes, when playing a note twice fast, the second
1417 note was silent
1418 - fixed crash happening when a pitch bend event arrived at the
1419 same time a new instrument was loading
1421 * LSCP server:
1422 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1423 react on MIDI data arriving on certain sampler channels (so far only
1424 Note-On and Note-Off events are sent via this LSCP event)
1425 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1426 react on MIDI data arriving on certain MIDI input devices (so far only
1427 Note-On and Note-Off events are sent via this LSCP event)
1428 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1430 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1431 frontends to send MIDI messages to specific sampler channel
1432 - added two additional fields to GET FILE INSTRUMENT INFO command -
1434 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1435 was incorrect
1436 - Optimized the retrieval of the MIDI instrument mappings
1437 - added new LSCP command "SET VOICES" to globally alter the maximum
1438 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1439 be triggered respectively
1440 - added new LSCP command "SET STREAMS" to globally alter the maximum
1441 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1442 which will be triggered respectively
1443 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1444 a gigedit file dialog is opened)
1445 - close all connections when LSCPServer is deleted
1446 - hard close of all sockets on exit
1447 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1448 driver
1450 * Bug fixes:
1451 - fixed a crash which occurs when removing a sampler channel waiting
1452 to start instrument loading after another channel
1453 - fixed a crash which occurs when removing a sampler channel with
1454 instrument loading in progress (bug #113)
1455 - fixed termination caused by uncaught exception when adding MIDI
1456 instrument with PERSISTENT load mode
1457 - fixed possible iterator invalidations when resetting the sampler
1458 - fixed memory leaks when issuing the following LSCP commands:
1463 - fixed possible compilation error when sqlite is not present
1464 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1465 - fixed crash when changing the audio output device of a sampler
1466 channel with loaded instrument and start playing notes
1467 - fixed endless loop in Engine::SuspendAll() (bug #120)
1468 - fixed a low-level atomic load function that was broken on 64-bit
1469 PowerPC, which probably could cause crashes on that platform
1470 - fixed a memory management error which could cause a crash when a
1471 plugin was unloaded
1472 - bugfix: two private structs had the same name, which could cause
1473 problems if the linker chose the wrong constructor
1474 - fixed low-level ConditionServer usage bug that caused lockups on
1475 Windows
1478 Version 0.5.1 (6 December 2007)
1480 * packaging changes:
1481 - added autoconf checks for pthread library
1482 - added autoconf check for pthread bug found on certain NPTL-enabled
1483 glibc versions (see Gentoo bug report #194076)
1484 - added autoconf checks for MS Windows
1486 * general changes:
1487 - bugfix: the thread used by an editor plugin didn't die when the
1488 editor closed
1489 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1490 out all the space. operator--() did not apply size_mask after
1491 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1492 order to avoid problems with the _NonVolatileReader functions.
1493 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1494 GetWriteSpace(). Since this function is currently only used in
1495 the stream's qsort() compare function, it didn't trigger any
1496 bugs.
1497 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1498 24bit mode too. Faster method to read 24bit words on little
1499 endian machines (x86): replaced 3 byte reads + shifts with a 1
1500 unaligned 32bit read and shift
1501 - experimental support for MS Windows (MIDI input via MME, AUDIO
1502 output via ASIO)
1503 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1504 - support for monitoring the total number of active disk streams
1505 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1508 * AUDIO driver:
1509 - added Windows ASIO low latency audio driver
1511 * MIDI driver:
1512 - added MME Windows MIDI driver
1514 * LSCP server:
1515 - added support for Windows style path / filenames, however with
1516 forward slash path separators instead of backslash
1517 (i.e. "C:/foo/bar.gig")
1518 - allow naughty liblscp to send non-string device parameters within
1519 apostrophes as well
1520 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1521 "LIST FILE INSTRUMENTS <file>" and
1522 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1523 about an arbitrary instrument file on the system where the sampler is
1524 running on
1526 Version 0.5.0 (15 October 2007)
1528 * packaging changes:
1529 - config.h is not going to be installed along with liblinuxsampler's
1530 API header files anymore
1531 - only the API relevant header (and source) files will be exported to
1532 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1533 - added completely new XCode project files for Mac OSX which is now
1534 capable to execute our autoconf environment, thus no need anymore
1535 to maintain the compile time configuration file (osx/version.h) for
1536 OSX manually (patch by Toshi Nagata)
1537 - fixed buggy boolean --enable-foo / --disable-foo configure script
1538 parameters
1539 - global.h now only covers global definitions that are needed for the
1540 C++ API header files, all implementation internal global definitions
1541 are now in global_private.h
1542 - atomic.h is not exposed to the C++ API anymore
1543 - no need to include config.h anymore for using LS's API header files
1544 - fixed warnings in API doc generation
1546 * general changes:
1547 - replaced the old, confusing MIDI program change mechanism by a
1548 flexible MIDI instrument mapper which allows to map arbitrary
1549 (MIDI bank, MIDI program) pairs with arbitrary
1550 (engine type, instrument file, file index) triplets which will be
1551 loaded on the respective channel when such MIDI program change
1552 messages arrive, beside that, each entry allows to define a life-time
1553 strategy for the instrument, so the user can define whether the
1554 instrument should i.e. be permanently loaded (to be able to switch
1555 quickly among sounds) or i.e. loaded just on demand when the
1556 respective program change arrives (to safe RAM space), as well as a
1557 global volume factor for each entry, so the user can adjust the volume
1558 dynamic of his mapped instrument collection without having to modify
1559 the instrument files, also one can manage arbitrary amount of such
1560 MIDI instrument maps and assign each sampler channel individually
1561 a certain map, so that i.e. separation of normal instruments and
1562 drumkits is possible
1563 - new notification events for tracking changes to audio/MIDI devices,
1564 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1565 - sampler was limited to load max. 200 instruments in the background
1566 due to a constant size RingBuffer FIFO which is now replaced by a
1567 dynamic (unlimited) size std::list FIFO
1568 - added FX sends, these allow to route audio signals to arbitrary audio
1569 output channels for being processed by external effect processors
1570 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1571 controllers
1572 - global (sampler wide) volume can now be controlled at runtime
1573 - Implemented new, improved notification system
1574 - fixed compilation errors regarding OSX
1575 (patch by Toshi Nagata)
1576 - implemented instruments database
1577 - added support for escape sequences to the instruments database
1578 - added highly experimental support for on-the-fly instrument editing
1579 within the sampler's process (by using instrument editor plugins),
1580 you'll notice the new "Registered instrument editors:" message on
1581 startup, added a new LSCP command:
1582 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1583 to spawn a matching instrument editor for the instrument on the
1584 given sampler channel, the plugin path can be overridden at compile
1585 time with ./configure --enable-plugin-dir=/some/dir
1586 - added experimental code for synchronizing instrument editors hosted
1587 in the sampler's process to safely edit instruments while playing
1588 without a crash (hopefully) by either suspending single regions
1589 wherever possible or if unavoidable whole engine(s)
1590 - fixed several issues in fundamental "Thread" class: set scheduling
1591 policy and priority on thread level, set a minimum stack size for
1592 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1593 threads simply inherited properties of starting thread instead of
1594 setting their own policy and priority
1595 - minor fix in our automatic stack trace mechanism on crashes, the
1596 main process did not wait for the stack trace process to finish
1597 its output
1598 - fixed some minor memory leaks
1599 - reenabled assembly features support, at the moment only for
1600 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1601 - minor assembly fix in x86 features detection (don't use the PIC
1602 register, to avoid relocations in the text segment at runtime)
1603 - POSIX callback functions of Thread.h are hidden
1605 * MIDI driver:
1606 - dispatch bank select (MSB and LSB) messages
1608 * audio driver:
1609 - the ALSA audio output driver parameters now reflect the correct
1610 parameter value ranges for the respective selected sound card
1611 (patch by Till Wimmer, a bit fixed and extended)
1613 * Gigasampler format engine:
1614 - if a filter is used and EG2 finishes before EG1, let the voice
1615 die when EG2 has finished (this fixes a problem with clicks and
1616 voice starvation for some gigs)
1617 - playback is no longer disabled during instrument loading
1618 - all notes playing on a channel that changes its instrument keep
1619 playing with the old instrument until they get a note off
1620 command
1621 - EG fix: a release value of zero could cause noises or crash
1622 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1623 - EG fine tuning: when attack is zero the EG starts at a level
1624 above max sustain level, which means that there is a decay phase
1625 even if sustain is 100%
1626 - more EG fixes: the level could sometimes go below zero and cause
1627 noises or crashes
1628 - minor fix of EGDecay (patch by Toshi Nagata)
1629 - fixed compiler error when --enable-override-filter-type was
1630 supplied to the configure script (fixes #46)
1631 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1632 instead of a fix value
1633 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1634 127 (solo mode) only kill voices if the respective mode really
1635 changed
1637 * LSCP server:
1638 - fixed compile time error for old Bison versions
1639 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1640 - parser now supports extended ASCII character set
1641 (up to ASCII code 255, i.e. includes now umlauts and accents)
1642 - filename arguments in LSCP commands now allow to use escape
1643 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1644 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1645 code value like \xf2) (fixes bug #24)
1646 - the following LSCP commands now also support escape sequences for at
1647 least one of their text-based parameters (i.e. name, description):
1654 - returns verbose syntax errors (line and column where syntax error
1655 occured, the unexpected character and the actually expected, possible
1656 character(s), the latter only if less than 5 possibilities)
1657 - made sure that LSCP syntax is not affected by gigedit locale
1658 settings
1659 - bugfix regarding strings parameter lists: all comma separated lists
1660 of strings were treated as being one string containing commas
1661 (fixes #57)
1663 * Bug fixes:
1664 - fixed crash occurring on certain LSCP scripts (Bug 39)
1665 - another thread safety fix for lscp "load engine" and "set
1666 channel audio output device"
1667 - fixed a crash which occurs when reassigning the same engine
1668 on a sampler channel with connected MIDI device
1669 - fixed a crash which occurs when changing the number of ports of a MIDI
1670 device connected to a sampler channel to number less then or equal
1671 to the index of the port to which the sampler channel is connected.
1672 - The previous bindings were not been disconnected when altering
1673 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1674 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1675 - The active stream/voice count statistic was incorrect.
1676 - notification events were not been sent for some sampler
1677 channel changes
1678 - added default min and max values to restrict the number of allowed
1679 audio output channels and MIDI input ports
1680 - the connection to the PCM interface is now closed when destroying
1681 an audio output device
1682 - files with slash in their path or filename could not be loaded
1684 * test cases:
1685 - updated and fixed (haven't been touched in a while)
1687 Version 0.4.0 (24 November 2006)
1689 * packaging changes:
1690 - changed deprecated copyright attribute to license; added ldconfig
1691 to post-(un)install steps; added devel package for liblinuxsampler;
1692 to linuxsampler.spec (RPM)
1693 - install necessary development header files for allowing 3rd party
1694 applications to link against liblinuxsampler
1695 - liblinuxsampler's API documentation can be generated with 'make docs'
1696 (Doxygen required)
1697 - added benchmark to automatically detect the best triangle LFO
1698 implementation (currently either an integer math solution or a
1699 di-harmonic approximation), automatic detection can be overriden
1700 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1701 configure script argument though (mandatory for cross-compilation)
1702 - do not automatically pick optimized gcc flags if the user already
1703 provided some on his own (as CXXFLAGS)
1704 - added compile time option to disable processing of All-Notes-Off MIDI
1705 messages
1706 - added compile time options to allow disabling the various audio and
1707 MIDI drivers
1708 - fixed automatic GCC CPU switch detection on PPC
1709 (patch by Ebrahim Mayat)
1711 * Gigasampler format engine:
1712 - extensive synthesis optimization
1713 (reimplementation of EGs and LFO(s), removed synthesis parameter
1714 prerendering and the synthesis parameter matrix in general, splitting
1715 each audio fragment into subfragments now where each subfragment uses
1716 constant pitch and filter coefficients. The volume coefficient is
1717 linearly interpolated inside a subfragment, unless
1718 --disable-interpolate-volume is set.)
1719 - fine tuning of the EG modulation parameters
1720 - improved filter cutoff calculation by adding support for the
1721 following gig parameters: Cutoff freq (used when no cutoff
1722 controller is defined), Control invert, Minimum cutoff, Velocity
1723 curve and Velocity range. The keyboard tracking now scales
1724 cutoff frequency instead of resonance.
1725 - added support for gig parameter Resonance.
1726 - fixed bug in sysex handling (patch by Juan Linietsky)
1727 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1728 which can be overridden with --enable-global-attenuation
1729 - EG fixes: made the length of "attack hold" stage more
1730 accurate. Release stage can now start before attack stage
1731 ends. Cancel release didn't work when sustain was zero. Attack
1732 time now has a minimal value to prevent clicks.
1733 - fixed pitch changes larger than one octave
1734 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1735 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1736 all modes can be altered via standard GM messages, that is CC5 for
1737 altering portamento time, CC65 for enabling / disabling portamento
1738 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1739 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1740 parameter) and crossfade
1741 - added support for the "attenuation controller threshold" gig
1742 parameter
1743 - added smoothing of volume changes caused by control change
1744 messages
1745 - sample loop parameters are now taken from the DimensionRegion
1746 instead of the wave chunk
1747 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1748 not equal to a power of two
1749 - reimplementation of the filter algorithm. The new filter is more
1750 accurate and supports all gig filter types, including bandreject
1751 and lowpass turbo.
1752 - real support for 24 bit samples - samples are not truncated to
1753 16 bits anymore
1754 - support for aftertouch (channel pressure, not polyphonic
1755 aftertouch)
1756 - LFO1 behaviour fixed (dampening from max volume instead of
1757 amplifying from 0)
1759 * LSCP server:
1760 - fixed application exit on broken pipe error (fixes bug #20)
1761 - fixed the notification messages delay due to lack of
1762 network activity (fixes bug #26)
1763 - fixed parser bug which occured on space(s) within device parameters
1766 * audio driver:
1767 - added aRts audio output driver (by no means RT safe)
1769 * MIDI driver:
1770 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1771 messages several times instead of once
1772 - API extension for MIDI drivers which already supply exact time stamps
1773 for events (i.e. for offline rendering based MIDI drivers)
1774 - added checks for bad MIDI data
1776 * linuxsampler application:
1777 - show available sampler engine types on startup
1779 * general changes:
1780 - support for muting sampler channels and solo mode of the same, two new
1781 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1782 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1783 introduced for this, the behavior is the same like on a mixer console
1784 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1785 --enable-process-muted-channels which can be used to enable the
1786 processing of muted channels.
1787 - support for sostenuto pedal
1788 - support for monitoring the total number of active voices
1791 - fixed some memory management errors
1792 - fixed some concurrency problems that could lead to crashes when
1793 LSCP commands were executed
1794 - fixed crash when instrument loading failed previously on the same
1795 sampler channel (fixes bug #36)
1797 Version 0.3.3 (15 July 2005)
1799 * packaging changes:
1800 - fixed compilation with gcc 4.0
1802 * Gigasampler format engine:
1803 - LFO preprocessing was performed even though the respective LFO was
1804 disabled by the instrument patch (minor efficiency fix)
1805 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1806 for volume ramp downs in the same fragment (needed for current voice
1807 stealing implementation) then simply inform the user with a warning
1808 about possible click sounds and reduce the volume ramp down
1809 appropriately instead of cancelling the audio device connection
1811 Version 0.3.2 (24 June 2005)
1813 * packaging changes:
1814 - updated autotools build files to compile on OS X
1815 (conditional compilation of CoreMIDI and MidiShare drivers)
1816 - hand-crafted assembly optimization code can be disabled with
1817 './configure --disable-asm' (definitely not recommended)
1818 - fixed 'make dist' rule to include all necessary files
1819 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1820 (due to 'dist-bzip2' automake option)
1822 * Gigasampler format engine:
1823 - support for the gig parameters for "release velocity response" curves
1824 - fine tuning of the EGADSR envelope
1825 - volume of release triggered samples now depends on note-on velocity,
1826 note length and gig parameter "release trigger decay" instead of
1827 note-off velocity.
1828 - revised voice stealing
1829 (fixes crash and endless loop caused by voice stealing)
1830 - don't reset scale tuning on instrument or audio output device change
1831 - handle key group conflicts right at the beginning of each fragment
1832 instead of when the respective voice is actually launched
1833 (fixes undefined behavior if stolen voices belonged to a key group -
1834 this case was followed by a "killed voice survived" error message)
1835 - fixed minor issue with null/silence samples
1836 (those stole voices even though they don't need a voice at all which
1837 resulted in "voice stealing didn't work out" messages)
1838 - don't reset volume, pan, pitch and MIDI controller values on
1839 instrument or audio output device change
1841 * LSCP server:
1842 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1843 - fixed LSCP event "CHANNEL_INFO" notification
1844 (e.g. did not notify on volume changes or MIDI program change events)
1846 * linuxsampler application:
1847 - added command line parameters --lscp-addr and --lscp-port to override
1848 default IP address and port of LSCP server
1850 Version 0.3.1 (24 May 2005)
1852 * initial release
