# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13        - Added public API C++ class "LFO", which is a cluster class encapsulating
14          all the sampler's LFO implementations to be used by 3rd party applications
15          (e.g. by Gigedit).
16        - Added int math square LFO implementation.
17        - Added int math saw LFO implementation.
18        - Added numeric complex nr sine LFO implementation.
19        - Marked class LFOTriangleDiHarmonic as deprecated
20          (will be removed in future).
21        - Added LFOAll.h which includes all LFO implementation's header files.
22        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25          SquareLFO -> LFOSquarePulse and separated the latter to its own header
26          file).
27        - Renamed type LFOSigned -> LFOTriangleSigned.
28        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29        - Using now cubic interpolation as resampling algorithm by default; and
30          linear interpolation is deprecated now.
31        - Event:Init(): memset() entire Event::Param union to zero instead of trying
32          to do that for its individual members; the latter became error prone due
33          to the union's growing complexity meanwhile.
34        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36          methods and marked the old ones as deprecated; and likewise added new
37          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38          methods and marked those old ones deprecated as well.
39        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41        - Implemented support for compressed RPN/NRPN message sequences (that is to
42          allow processing MIDI data entry messages without always having to be
43          preceded strictly by RPN/NRPN parameter selection messages on each value
44          change).
45        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46          decrement).
47    
48      * Real-time instrument scripts:
49        - Added method ScriptVM::setExitResultEnabled() which allows to
50          explicitly enable the built-in exit() function to optionally accept
51          one function argument; the value of the passed exit() function
52          argument will then become available by calling
53          VMExecContext::exitResult() after script execution.
54        - 64 bit support for NKSP integer scripts variables (declare $foo).
55        - Variable names, function names and preprocessor condition names must start
56          with a regular character (a-z or A-Z); starting them with a digit or
57          underscore is not allowed.
58        - NKSP parser fix: equal comparison operator "=" and not equal comparison
59          operator "#" must only accept integer operands.
60        - NKSP language: Implemented support for standard units like Hertz, seconds,
61          Bel including support for metric unit prefixes; so one can now e.g.
62          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
63          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
64          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
65        - NKSP language: Introduced "final" operator "!" which is specifically
66          intended for synthesis parameter values to denote that the synthesis
67          parameter value is intended to be the "final" value for that synthesis
68          parameter that should explicitly be used by the engine and thus causing
69          the sampler engine to ignore all other modulation sources for the same
70          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
71          variable or formula with this new "!" operator the expression is marked as
72          being "final".
73        - NKSP script editor API: Added support for detecting standard unit tokens
74          and their potential metric prefix token.
75        - NKSP language: Added support for NKSP real number literals and
76          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
77        - NKSP language: Added support for NKSP real number (floating point) script
78          variables (declare ~foo).
79        - NKSP language: Added support for NKSP real number (floating point) array
80          script variables (declare ?foo[]).
81        - Built-in script function "message()" accepts now real number argument as
82          well.
83        - Added built-in script function "real_to_int()" and its short hand form
84          "int()" for casting from real number to integer in NKSP scripts.
85        - Added built-in script function "int_to_real()" and its short hand form
86          "real()" for casting from integer to real number in NKSP scripts.
87        - Allow built-in exit() function to potentially accept real number type
88          argument as well.
89        - Built-in script functions may have a different return type depending on
90          the arguments passed to the function.
91        - Built-in script function "abs()" optionally accepts and returns real
92          number.
93        - Built-in script functions "min()" and "max()" optionally accept real
94          number arguments and return real number as result in that case.
95        - NKSP VM API: Allow units and 'final'ness to be returned as result from
96          built-in functions (added methods VMFunction::returnUnitType() and
97          VMFunction::returnsFinal() for that purpose which must be implemented by
98          built-in function implementations).
99        - NKSP language: Allow metric unit prefixes of numeric scalar and array
100          variables to be changed freely at runtime (unlike unit types like Hz etc.
101          which are still sticky, parse-time features of variables which cannot be
102          changed at runtime for the intentional sake of determinism).
103        - NKSP language: 'final' values are prohibited for array variables for now
104          (attempt causes a parsers error).
105        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
106          conditions of runtime control structures like if(), while(), select()
107          (attempt causes a parser error).
108        - NKSP VM API: Allow built-in functions to perform their own, individual
109          parse time checks of arguments going to be passed to the function at
110          runtime (added method VMFunction::checkArgs() for that purpose).
111        - NKSP language: raise parser warning if only one operand of binary
112          operators (like logical 'or' comparison) contain a 'final' value (because
113          it would always yield in a 'final' result in such cases).
114        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
115          different metric unit prefixes, which will behave as expected (e.g.
116          result of expression '1000us < 2ms' is true).
117        - NKSP language: Allow adding values with different metric unit prefixes
118          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
119        - NKSP language: Allow subtracting values with different metric unit
120          prefixes (e.g. result of expression '1ms - 20us' is '980us').
121        - NKSP language: Allow multiplying with any metric unit prefixes
122          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
123          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
124          we don't have any considerable practical use for a term like '4s^2'
125          (hence any attempt multiplying two unit types still causes parser error).
126        - NKSP language: Allow dividing by any metric unit prefixes and allow
127          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
128          yields in unit free result '8'). So this is now a way to cast units away
129          e.g. for passing the result to other expressions, certain function calls
130          or variables which are not accepting any units (or that specific unit).
131        - NKSP language: integer arrays and real number arrays can now be converted
132          to strings (e.g. for dumping their content with message() calls for
133          script debugging purposes).
134        - NKSP language: expressions and variables with units are now correctly
135          casted to strings (e.g. with message() calls).
136        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
137          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
138          floating point tolerances into account.
139        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
140          VMScalarNumberExpr::evalCastReal().
141        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
142          'VMIntArrayExpr' and 'VMRealArrayExpr'.
143        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
144          unitFactor() (runtime) methods.
145        - Built-in function "exit()" supports now returning units and 'final'ness
146          for test cases.
147        - The following built-in functions support now units as well: "abs()",
148          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
149          "real_to_int()", "int()", "int_to_real()" and "real()".
150        - Built-in functions "array_equal()", "search()" and "sort()" support now
151          real number arrays (correctly) as well.
152        - Added individual parse time checks of arguments to be passed to built-in
153          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
154          "array_equal()" and "search()" specific for their individual purposes.
155        - NKSP VM refactoring: Renamed all methods, functions and classes matching
156          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
157          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
158          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
159          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
160          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
161          isScalarNumber() -> isNumber()).
162        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
163          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
164          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
165          as convenient methods for automatically converting values to expected
166          metric value basis.
167        - Built-in function "wait()" accepts now both integers and real numbers as
168          argument.
169        - NKSP VM API cleanup: Get rid of legacy method
170          VMFunction::argType(vmint iArg) which was already superseded by its new
171          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
172        - NKSP parser: if wrong argument type was passed to a built-in function and
173          that built-in function accepts more than one data type for the argument,
174          then show all supported data types as parser error message.
175        - Built-in function "play_note()" accepts now real numbers and seconds as
176          unit type as well for its 3rd and 4th function arguments.
177        - The following built-in functions accept now real numbers as well for their
178          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
179          "change_attack()", "change_decay()", "change_release()",
180          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
181          "change_cutoff_sustain()", "change_cutoff_release()",
182          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
183          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
184          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
185        - Fixed built-in function "change_play_pos()" not having accepted metric
186          prefixes at all.
187        - Fixed the following built-in functions having misinterpreted values given
188          with unit type (for their 2nd argument) as if they were relative values
189          (that is as if they were passed without a unit type): "change_attack()",
190          "change_decay()", "change_release()", "change_cutoff_attack()",
191          "change_cutoff_decay()", "change_cutoff_release()".
192        - Fixed the following built-in functions having applied completely wrong
193          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
194          respective EGs being their modulation sink assume uint data type with
195          value range 0..1000 instead of 0.0..1.0.
196        - Added individual parse-time checks of function arguments for the following
197          built-in functions: "play_note()", "note_off()", "set_event_mark()",
198          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
199          "change_decay()", "change_release()", "change_cutoff_attack()",
200          "change_cutoff_decay()", "change_cutoff_release()",
201          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
202          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
203          "change_pan_time()".
204        - Don't abort function call if unit type was used and at the same time
205          'final' operator was omitted for the primary value argument of the
206          following built-in functions: "change_cutoff()", "change_attack()",
207          "change_decay()", "change_release()", "change_cutoff_attack()",
208          "change_cutoff_decay()", "change_cutoff_release()",
209          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
210          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
211          "change_pan_time()", instead imply 'final'ness at runtime and raise an
212          appropriate parser warning at parse time.
213        - Added built-in real number functions "round()", "ceil()", "floor()",
214          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
215          "cos()", "tan()", "asin()", "acos()", "atan()".
216        - Added built-in script real number constant "~NI_MATH_PI".
217        - Added built-in script real number constant "~NI_MATH_E".
218        - NKSP language: Allow unary '+' operator.
219        - Added built-in script functions "msb()" and "lsb()".
220        - NKSP language: Added support for RPN event handler
221          ("on rpn ... end on" in instrument scripts).
222        - NKSP language: Added support for NRPN event handler
223          ("on nrpn ... end on" in instrument scripts).
224        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
225          may be read from the new RPN/NRPN script handlers to get the (N)RPN
226          parameter that had been changed and its new value.
227        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
228          which are identifying the new (N)RPN handlers as such at script runtime.
229        - Implemented built-in script function "set_rpn()".
230        - Implemented built-in script function "set_nrpn()".
231    
232      * test cases:
233        - Fixed compiler errors in test cases.
234        - Updated README for how to compile & run test cases.
235        - Updated test case
236          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
237          expected behaviour of the Mutex class implementation (recursive
238          mutex type).
239        - Added test cases for NKSP core language aspects and core built-in
240          functions.
241        - Fixed thread tests segfaulting on Linux.
242        - NKSP: Added real number test cases for built-in functions exit(),
243          int_to_real(), real(), real_to_int() and int(), as well as for the
244          plus, minus and negate language operators.
245        - Added massive amount of NKSP test cases for standard measuring units and
246          'final' operator usage cases.
247        - Added NKSP test cases for (floating point tolerance aware) real number
248          equalness / unequalness comparison.
249        - Added NKSP int array and real array tests for value assignment and
250          initialization of arrays.
251        - Added NKSP test cases for built-in functions "round()", "ceil()",
252          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
253          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
254        - Added NKSP test cases for unary '+' operator.
255        - Added NKSP test cases for core built-in variables.
256    
257      * GigaStudio/Gigasampler format engine:
258        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
259          behaviour for start_level_mid.
260        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
261          level (see discussion "GigaStudio LFO compatibility" on mailing list
262          from 2019-09-26 for details).
263        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
264          see discussion "GigaStudio LFO compatibility" on mailing list from
265          2019-09-26 for details).
266        - Format extension: Added support for different LFO wave forms (currently
267          either sine [default], triangle, saw or square).
268        - Format extension: Added support for LFO phase displacement (0°..360°).
269        - Format extension: Added support for flipping LFO polarity on LFO 3
270          (in the original gig format this was only available for LFO 1 and LFO 2).
271        - Format extension: Support for additional filter types:
272          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
273          bandreject 2-pole.
274    
275      * SFZ format engine:
276        - Fixed support for regions with loccN/hiccN conditions on more than one
277          MIDI controller.
278    
279      * Benchmarks:
280        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
281          algorithm (since result of 2nd run was not accumulated).
282        - Added benchmark for saw wave (benchmarks/saw.cpp).
283        - Added benchmark for sine wave (benchmarks/sine.cpp).
284        - Added benchmark for square wave (benchmarks/square.cpp).
285        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
286          which are large enough on modern systems.
287    
288    Version 2.1.1 (27 Jul 2019)
289    
290      * Real-time instrument scripts:
291        - Fixed behavior of built-in NKSP functions change_sustain(),
292          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
293          and change_cutoff_release().
294    
295      * general changes:
296        - Only play release trigger samples on sustain pedal up if this behaviour
297          was explicitly requested by the instrument (otherwise only on note-off).
298        - Fixed compiler warnings.
299        - Fixed compilation error when cross-compiling to Mac.
300        - FX Sends: Provide more useful error messages on routing problems
301          (see bug #169).
302        - LSCP doc: Be more clear describing the two distinct approaches
303          of using external vs. internal effects (see bug #169).
304        - "optional" class: Fixed comparison operators.
305    
306      * Gigasampler/GigaStudio format engine:
307        - Format extension: If requested by instrument then don't play release
308          trigger sample on note-off events.
309    
310      * SFZ format engine:
311        - Fixed memory leak when releasing samples
312          (fixes bug #307, patch by Jacek Roszkowski)
313        - Fixed potential crash when a sample is shared by more than one region
314          (fixes bug #308, patch by Jacek Roszkowski).
315        - Opcode 'sample': Added support for built-in sample '*silence'
316          (fixes bug #310, patch by Jacek Roszkowski).
317    
318    Version 2.1.0 (25 Nov 2017)
319    
320      * SFZ format engine:
321        - added support for <global>, <master> and #define (patch by Alby M)
322        - Removed code duplication in SFZ file loading code.
323        - Added support for sfz extension opcode 'script' which may be used to
324          load real-time instrument script file (NKSP script language).
325        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
326        - Fixed unintended volume fade-in of voices under certain conditions.
327        - sfz parser: allow missing space between header and opcode
328    
329      * Gigasampler/GigaStudio format engine:
330        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
331          cutoff settings.
332        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
333          all if an up-pitch of more than 40 semi tones was requested (I don't
334          think there is any stock gig sound that requires this behavior to
335          resemble its original sound).
336        - Added support for controlling whether the individual EGADSR stages may
337          be aborted (as LinuxSampler extension to the original GigaStudio 4
338          format).
339    
340      * general changes:
341        - fixed printf type errors (mostly in debug messages)
342        - use unique_ptr instead of auto_ptr when building with C++11
343        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
344          allowing to sort data efficiently in real-time safe manner.
345        - RTList class: added methods for moving/inserting elements to arbitrary
346          position within a list.
347        - RTList class: added method fromPtr() for creating an Iterator object from
348          a raw element pointer.
349        - Attempt to partly fix resetting engine channels vs. resetting engine, an
350          overall cleanup of the Reset*(), ConnectAudioDevice(),
351          DisconnectAudioDevice() API methods would still be desirable though,
352          because the current situation is still inconsistent and error prone.
353        - Active voices are now internally grouped to "Note" objects, instead of
354          being directly assigned to a keyboard key. This allows more fine graded
355          processing of voices, which is i.e. required for certain instrument
356          script features.
357        - Fix: Release trigger voices were not spawned on sustain pedal up
358          (CC #64) events.
359        - Fix: Release trigger voices can now also distinguish correctly between
360          note-off and sustain pedal up events.
361        - All engines: Increased ramp speed of volume smoother and pan smoother
362          (while slow rate of crossfade smoother is preserved) to allow quick
363          volume and pan changes by instrument scripts for instance.
364        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
365          properly and thus were ignored for certain uses.
366        - Added new C++ API method
367          VirtualMidiDevice::SendChannelPressureToSampler().
368        - windows, 32-bit: fixed potential crashes by making sure the stack in
369          sub threads is 16-byte aligned
370        - fixed numerous compiler warnings
371        - Fixed invalid (note-on) event ID being assigned to new Note objects.
372        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
373          fixes potential undefined behavior.
374        - Fixed Note object leak when triggering notes on keys which did not
375          have a valid sample mapped (fixes bug #252).
376        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
377        - linuxsampler binary fix: option --create-instruments-db ignored
378          subsequent optional argument due to glibc's implementation oddity
379          which expects a "=" sign, but no space between them.
380    
381      * packaging changes:
382        - removed unnecessary dependency to libuuid
383          (originated by libgig's usage of it)
384        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
385          auto detect whether it (sh/c)ould output its messages in color.
386        - Debian: Fixed packaging error about invalid "Source-Version"
387          substitution variable.
388        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
389        - Debian: Added build dependency to libsqlite3-dev for building
390          linuxsampler with instruments DB support.
391    
392      * Real-time instrument scripts:
393        - Implemented scheduler for delayed MIDI events and for suspended scripts.
394        - Built-in script function "wait()": implemented support for function's
395          "duration-us" argument, thus scripts using this function are now
396          correctly resumed after the requested amount of microseconds.
397        - Built-in script function "play_note()": implemented support for
398          function's "duration-us" argument, thus notes triggered with this
399          argument are now correctly released after the requested amount of
400          microseconds.
401        - Fix: script events were not cleared when engine channel was reset,
402          potentially causing undefined behavior.
403        - Fixed crash which happened when trying to reference an undeclared
404          variable.
405        - Built-in script function "play_note()": Added support for passing
406          special value -1 for "duration-us" argument, which will cause the
407          triggered note to be released once the original note was released.
408        - Instrument script classes now exported with the liblinuxsampler C++ API.
409        - Added new API method ScriptVM::syntaxHighlighting() which provides
410          a convenient syntax highlighting backend for external instrument
411          script editor applications.
412        - Added new C++ API class "ScriptVMFactory".
413        - Extended parser issues to provide not only first line and first
414          column, but also last line and last column of issue (thus marking
415          the precise span of the issue within the source code).
416        - Reload script automatically after being modified by an instrument
417          editor.
418        - NKSP language grammar correction: allow empty event handler bodies
419          like "on note end on".
420        - Implemented built-in script function "change_vol()".
421        - Implemented built-in script function "change_tune()".
422        - Implemented built-in script function "change_pan()".

424        - Implemented built-in script function "change_reso()".
425        - Implemented built-in script function "event_status()".
426        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
427          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
428          "event_status()" function.
429        - NKSP language: Added support for bitwise operators ".or.", ".and."
430          and ".not.".
431        - NKSP language scanner: Fixed IDs matching to require at least one
432          character (i.e. when matching function names or variable names).
433        - NKSP language scanner: disabled unusued rules.
434        - Fixed behavior of play_note() and note_off() functions which must
435          be distinguished engine internally from "real" MIDI note on/off
436          events in order to avoid misbehaviors like hanging notes.
437        - Implemented built-in script variable "$KSP_TIMER".
438        - Implemented built-in script variable "$NKSP_REAL_TIMER".
439        - Implemented built-in script variable "$NKSP_PERF_TIMER".
440        - Implemented built-in script variable "$ENGINE_UPTIME".
441        - Implemented built-in script function "inc()".
442        - Implemented built-in script function "dec()".
443        - NKSP language fix: division expressions were evaluated too often.
444        - NKSP language fix: string concatenation operator was right
445          associative instead of left (to right).
446        - NKSP language correction: allow empty statements in entire language
447          (i.e. "if end if").
448        - Implemented built-in script function "stop_wait()".
449        - Implemented built-in script variable "$NI_CALLBACK_ID".
450        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
451        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
452        - Added support for read-only built-in variables (respectively
453          handled by the script parser).
454        - Added built-in script constant "$NI_CB_TYPE_INIT".
455        - Added built-in script constant "$NI_CB_TYPE_NOTE".
456        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

460        - Implemented built-in script function "change_decay()".
461        - Implemented built-in script function "change_release()".
462        - Fixed all change_*() built-in script functions to apply their
463          synthesis parameter changes immediately in case the respective note
464          was triggered at the same time, instead of scheduling the parameter
465          change, especially because it would cause some parameter types's
466          changes either to be ramped (i.e. change_vol()) or other types even
467          to have not effect at all (i.e. change_attack()).
468        - Implemented built-in script function "sh_left()".
469        - Implemented built-in script function "sh_right()".
470        - Implemented built-in script function "min()".
471        - Implemented built-in script function "max()".
472        - NKSP Fix: "init" event handler was not always executed when a script
473          was loaded.
474        - NKSP built-in wait() script function: abort script execution if
475          a negative or zero wait time was passed as argument (since this is
476          a common indication of a bug either of the script or even of the
477          engine, which could lead to RT instability or even worse).
478        - ScriptVM: Implemented automatic suspension of RT safety
479          threatening scripts.
480        - Provide more user friendly error messages on syntax errors.
481        - Fixed NKSP parser warning "Not a statement" when assigning an
482          initializer list to an array variable.
483        - Implemented built-in script array variable "%ALL_EVENTS".
484        - Implemented built-in script function "in_range()".
485        - Implemented built-in script function "change_amp_lfo_depth()".
486        - Implemented built-in script function "change_amp_lfo_freq()".
487        - Implemented built-in script function "change_pitch_lfo_depth()".
488        - Implemented built-in script function "change_pitch_lfo_freq()".
489        - Implemented built-in script function "change_vol_time()".
490        - Implemented built-in script function "change_tune_time()".
491        - Implemented built-in script function "fade_in()".
492        - Implemented built-in script function "fade_out()".
493        - Fixed acceptance of wrong data type of parameters passed to built-in
494          script functions "change_vol()", "change_tune()", "change_pan()",
495          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
496          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
497          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
498        - Added built-in script function "get_event_par()" and implemented some
499          of its possible parameter selections.
500        - Added built-in script function "set_event_par()" and implemented some
501          of its possible parameter selections.
502        - Fixed a bunch of scheduler time related bugs.
503        - Fixed polyphonic variables not being reset to zero after usage.
504        - Built-in "ignore_event()" function: argument is now optional, like with
505          built-in function "ignore_controller()".
506        - Implemented built-in script function "change_velo()".
507        - Implemented built-in script function "change_note()".
508        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
509          intuitive behavior if used in combination with "change_vol_time()" or
510          "change_tune_time()" respectively: now tuning/volume changes are only
511          assigned (without delay) immediately to a new note if the respective
512          timing function has not been called before, otherwise the volume/tuning
513          changes are automatically faded (before, only the event's time stamp was
514          relevant).
515         - Implemented built-in script function "array_equal()".
516         - Implemented built-in script function "search()".
517         - Implemented built-in script function "sort()".
518         - NKSP Fix: Never suspend "init" event handlers.
519         - Implemented built-in script function "same_region()" (currently only
520           available for gig format engine).
521         - Added built-in script constant "$NKSP_LINEAR".
522         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
523         - Implemented built-in script function "change_vol_curve()".
524         - Implemented built-in script function "change_tune_curve()".
525         - built-in "play_note()" function now supports a sample playback start
526           offset with argument 3, where special value -1 means to use the regular
527           sample offset as defined by the instrument file.
528         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
529         - Built-in variable $EVENT_NOTE is now a read-only variable.
530         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
531         - built-in "play_note()" function now accepts -2 for its fourth argument
532           (note duration) which means the life time of the note shall be sticked
533           to the requested note number of argument 1.
534         - Fix: built-in "play_note()" function now returns 0 as result value if
535           -1 was passed for its fourth argument (note duration) and the respective
536           parent note is already gone.
537        - Implemented built-in script function "change_play_pos()".
538        - NKSP language: Added support for user declared const array variables.
539        - NKSP language: Raise parser warning if array variable is accessed with
540          an index that exceeds the array's size.
541        - NKSP language fix: Unknown characters were not handled correctly.
542        - NKSP language: Added support for "synchronized .. end synchronized"
543          code blocks.
544        - Implemented built-in script function "abort()" which allows to abort
545          another script handler by passing its callback ID.
546        - Fixed potential memory access bug and potential undefined behavior of
547          "init" event handlers.
548        - Print a time stamp along to each call of built-in function "message()".
549        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
550          to retrieve all code blocks filtered out by the preprocessor.
551        - Added built-in script function "fork()".
552        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
553        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
554        - Fixed potential crash when accessing dynamic built-in array variables.
555        - Added built-in script function "callback_status()".
556        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
557        - Added built-in constant $CALLBACK_STATUS_QUEUE.
558        - Added built-in constant $CALLBACK_STATUS_RUNNING.
559        - Removed max. value limitation of built-in functions "change_attack()",
560          "change_decay()" and "change_release()" to i.e. allow passing 2000000
561          for doubling the respective time.
562        - NKSP script editor syntax highlighting API: Fixed app termination due
563          to a lexer start condition stack underrun.
564        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
565          USE_CODE_IF_NOT() preprocessor statements.
566        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
567          can be set to disable all subsequent built-in "message()" function calls
568          on preprocessor level.
569        - Implemented built-in script function "change_sustain()".
570        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
571          to avoid the editor app to crash on ill-formed text input.
572        - Added built-in script function "change_pan_time()".
573        - Added built-in script function "change_pan_curve()".
574        - Added built-in script function "change_cutoff_attack()".
575        - Added built-in script function "change_cutoff_decay()".
576        - Added built-in script function "change_cutoff_sustain()".
577        - Added built-in script function "change_cutoff_release()".
578        - Added built-in script function "change_cutoff_lfo_depth()".
579        - Added built-in script function "change_cutoff_lfo_freq()".
580    
581      * Instruments DB:
582        - Fixed memory access bug of general DB access code which lead to
583          undefined behavior.
584        - Cleanup of instruments DB file creation and opening code.
585        - The instrument DB path of linuxsampler's --create-instruments-db argument
586          is now optional, if it is missing, then a default location is used.
587        - Added support for scanning SFZ (.sfz) files.
588        - Added support for scanning Sound Font (.sf2) files.
589        - Fixed undefined DB transaction behavior.
590    
591    Version 2.0.0 (15 July 2015)
592    
593      * packaging changes:
594        - fixed building with newer MinGW-w64
595        - Mac OS X: support the new dir for Core Audio SDK
596        - Mac OS X: fixed building outside source directory
597        - made sure all source files for hostplugins are included when
598          doing "make dist"
599        - removed empty directories left from the cvs to svn migration
600        - fixed compilation with gcc 4.6.1
601        - another "make dist" fix, for the LV2 plugin
602        - made --enable-pthread-testcancel default on Mac OS X
603        - minor Makefile fix for building lscpparser when build and source
604          directories are separate
605        - Mac OS X: made it possible to specify plugin installation dir to
606          configure
607        - Mac OS X: Makefile fix for the install-strip target
608        - fixed compilation with gcc 4.7
609        - fixed configure script error with old autoconf versions
610        - lsatomic.h: use gcc provided atomic functions if building with
611          gcc 4.7 and C++11
612        - modernized configure script
613        - fixed linkage error when building with
614          LDFLAGS="-Wl,--no-undefined" (#190)
615        - fixed compilation with Clang 3.2
616        - removed usage of deprecated Automake variable INCLUDES
617        - fixed building with C++11
618        - build fix: ChangeFlagRelaxed.h was missing in makefile
619        - build fix: libsndfile compiler flags were missing in some
620          makefiles
621        - fix for building with bison 3.0 (#202)
622        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
623          on the process's main thread
624        - fixed build error on newer MinGW
625        - support building with older jack versions
626        - support building with spaces in vst sdk path
627        - enabled automake 'subdir-objects' option and moved external
628          source references (vst, au, asio) from makefiles to cpp files,
629          in order to get rid of warnings from automake 1.14
630    
631      * general changes:
632        - Refactoring: moved the independent code from
633          the Gigasampler format engine to base classes
634        - command line option '--profile' is currently disabled, since the
635          respective profiling code is currently broken
636        - Introduced support for optional environment variable
637          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
638          where the sampler shall look for instrument editor plugins
639          (patch by Luis Garrido, slightly modified).
640        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
641        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
642        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
643          note (in this implementation of the sampler its simply hard routed to
644          the 1st effect send of the sampler channel, no matter what the actual
645          effect type is)
646        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
647          note (in this implementation of the sampler its simply hard routed to
648          the 2nd effect send of the sampler channel, no matter what the actual
649          effect type is)
650        - implemented support for internal LADSPA effects
651        - raised limit of program change queue from 100 to 512
652          (as suggested by Alex Stone)
653        - implemented sine LFO, pulse LFO and saw LFO
654        - experimental support for per voice equalization
655        - added command line option --exec-after-init
656        - Introduced new C++ API method:
657          EngineChannel::InstrumentFileName(int index)
658          allowing to retrieve the whole list of files used for the loaded
659          instrument on an engine channel (a.k.a. part). Some GigaStudio
660          instruments for example are splitted over several files like
661          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
662        - Added new C++ API method Sampler::GetGlobalMaxVoices().
663        - Added new C++ API method Sampler::GetGlobalMaxStreams().
664        - Added new C++ API method Sampler::SetGlobalMaxVoices().
665        - Added new C++ API method Sampler::SetGlobalMaxStreams().
666        - Various "const" and "restrict" optimizations.
667        - all engines: add pan CC value to instrument pan parameter before
668          applying panning, instead of using two separate pan functions in
669          series (#182)
670        - added a lock guard class for exception safe mutex handling and
671          used it everywhere appropriate
672        - Immediately apply scale tuning changes to active voices.
673        - Exposed scale tuning to C++ API (along to the already existing standard
674          SysEx way).
675        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
676          and broken for ppc64. (Seq_cst loads and stores are actually not
677          used in LS, so the bug wasn't noticable.)
678        - lsatomic.h: added ARMv7 support
679        - Added support for multiple MIDI input ports per sampler channel (and
680          added various new C++ methods for this new feature / design change, old
681          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
682          as deprecated but are still there and should provide full behavior
683          backward compatibility).
684        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
685          unsafe and caused compilation error with clang 2.x).
686        - Bugfix: only process the latest MIDI program change event.
687        - Introducing the LSCP shell, which provides convenient control of the
688          sampler from the command line by providing LSCP aware features.
689        - VirtualMidiDevice: Added support for program change.
690        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
691        - VirtualMidiDevice: Added support for pitch bend.
692        - Aftertouch: extended API to explicitly handle channel pressure and
693          polyphonic key pressure events (so far polyphonic pressure was not
694          supported at all, and channel pressure was rerouted as CC128 but not
695          used so far).
696        - Added initial support for real-time instrument scripts. The script VM
697          code is shared by all sampler engine implemementations, however only the
698          gig file format currently provides support for storing instrument scripts
699          (as LinuxSampler extension to the original GigaStudio 4 format).
700    
701      * Gigasampler format engine:
702        - implemented the "round robin keyboard" dimension
703        - fixed round robin and random dimensions for cases when number of
704          dimension zones is not a power of two
705        - made round robin use a counter for each region instead of each

958        - MME bugfix: driver wasn't closed properly
959        - CoreMIDI: automatically connect to all input sources by default (driver
960          parameter "AUTO_BIND").

962        - CoreMIDI: fixed minor memory leak
963    
964      * audio driver:

1083        - fixed crash which occurred when changing an already deployed sampler
1084          channel to a different engine type
1085        - fixed crash when deleting a sampler channel or changing engine
1086          type while an instrument load was in progress
1087        - bugfix: playing a note while changing the instrument could cause
1088          a crash, or give "Handing back unknown region" error messages
1089        - bugfix: calling SET VOICES (which Fantasia does on start and
1090          refresh) could cause instruments to be unloaded
1091        - Mac OS X: fixed name collision of enum in EffectControl and
1092          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1093        - Mac OS X: fixed hanging threads
1094        - Windows: disabled the previous thread fix on non-Mac systems, as
1095          it caused hanging threads on Windows
1096        - Fixed possible crashes due to corrupted MIDI/audio device list
1097          after MIDI/audio device creation failure
1098        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1099          instruments were uselessly precached with zero samples, however it still
1100          took the full preloading time and on 1st program change the respective
1101          instrument was completely reloaded again.
1102        - fixed handling of rapid bank select and program change messages
1103          sent to the same sampler channel (patch from the Open Octave
1104          project, slightly adjusted)

1115        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1116        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1117          introduced in previous fix)
1118        - fixed crash when a channel received a program change while
1119          playing a note in a key group
1120        - fixed erroneous error message piping in VoiceBase.h
1121          (labelled "Disk stream not available in time")
1122        - Update effects on sample rate & period size changes (to avoid
1123          crashes and noise on such transitions).
1124        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1125          (fixes #208)
1126        - Fixed bug in LSCP grammar definition which caused a statement like
1127          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1128          practically irrelevant, however it caused problems with the new LSCP
1129          shell's auto completion feature).
1130        - Fixed MIDI program change messages being ignored if quickly executed
1131          after each other (fixes #231).
