3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13        - Added public API C++ class "LFO", which is a cluster class encapsulating
14          all the sampler's LFO implementations to be used by 3rd party applications
15          (e.g. by Gigedit).
16        - Added int math square LFO implementation.
17        - Added int math saw LFO implementation.
18        - Added numeric complex nr sine LFO implementation.
19        - Marked class LFOTriangleDiHarmonic as deprecated
20          (will be removed in future).
21        - Added LFOAll.h which includes all LFO implementation's header files.
22        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25          SquareLFO -> LFOSquarePulse and separated the latter to its own header
26          file).
27        - Renamed type LFOSigned -> LFOTriangleSigned.
28        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29        - Using now cubic interpolation as resampling algorithm by default; and
30          linear interpolation is deprecated now.
31        - Event:Init(): memset() entire Event::Param union to zero instead of trying
32          to do that for its individual members; the latter became error prone due
33          to the union's growing complexity meanwhile.
34        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36          methods and marked the old ones as deprecated; and likewise added new
37          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38          methods and marked those old ones deprecated as well.
39        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41        - Implemented support for compressed RPN/NRPN message sequences (that is to
42          allow processing MIDI data entry messages without always having to be
43          preceded strictly by RPN/NRPN parameter selection messages on each value
44          change).
45        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46          decrement).
47        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48          MSB=127 and LSB=127) and which is disabling subsequent data
49          entry/increment/decrement CC messages.
50        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51          instrument editor.
52        - Fixed playing noise at the end of a disk stream under certain conditions.
53        - Fixed potential crash with high pitch at end of RAM playback.
54        - Added configure checks whether C++ compiler supports so called
55          'designated initializers'.
56        - Added global backtraceAsString() function for debugging purposes
57          (POSIX systems only, no Windows implementation yet).
58        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59          nameOfCaller() and setNameOfCaller().
60        - configure: Always check for availability of pthread_testcancel() and use
61          it if so (previously it was only used if explicitly enabled by configure
62          option).
63        - Thread class: raise compiler warning if pthread_testcancel() is not
64          available, because it can lead to deadlocks.
65    
66      * Real-time instrument scripts:
67        - Added method ScriptVM::setExitResultEnabled() which allows to
68          explicitly enable the built-in exit() function to optionally accept
69          one function argument; the value of the passed exit() function
70          argument will then become available by calling
71          VMExecContext::exitResult() after script execution.
72        - 64 bit support for NKSP integer scripts variables (declare $foo).
73        - Variable names, function names and preprocessor condition names must start
74          with a regular character (a-z or A-Z); starting them with a digit or
75          underscore is not allowed.
76        - NKSP parser fix: equal comparison operator "=" and not equal comparison
77          operator "#" must only accept integer operands.
78        - NKSP language: Implemented support for standard units like Hertz, seconds,
79          Bel including support for metric unit prefixes; so one can now e.g.
80          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
81          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
82          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
83        - NKSP language: Introduced "final" operator "!" which is specifically
84          intended for synthesis parameter values to denote that the synthesis
85          parameter value is intended to be the "final" value for that synthesis
86          parameter that should explicitly be used by the engine and thus causing
87          the sampler engine to ignore all other modulation sources for the same
88          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
89          variable or formula with this new "!" operator the expression is marked as
90          being "final".
91        - NKSP script editor API: Added support for detecting standard unit tokens
92          and their potential metric prefix token.
93        - NKSP language: Added support for NKSP real number literals and
94          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
95        - NKSP language: Added support for NKSP real number (floating point) script
96          variables (declare ~foo).
97        - NKSP language: Added support for NKSP real number (floating point) array
98          script variables (declare ?foo[]).
99        - Built-in script function "message()" accepts now real number argument as
100          well.
101        - Added built-in script function "real_to_int()" and its short hand form
102          "int()" for casting from real number to integer in NKSP scripts.
103        - Added built-in script function "int_to_real()" and its short hand form
104          "real()" for casting from integer to real number in NKSP scripts.
105        - Allow built-in exit() function to potentially accept real number type
106          argument as well.
107        - Built-in script functions may have a different return type depending on
108          the arguments passed to the function.
109        - Built-in script function "abs()" optionally accepts and returns real
110          number.
111        - Built-in script functions "min()" and "max()" optionally accept real
112          number arguments and return real number as result in that case.
113        - NKSP VM API: Allow units and 'final'ness to be returned as result from
114          built-in functions (added methods VMFunction::returnUnitType() and
115          VMFunction::returnsFinal() for that purpose which must be implemented by
116          built-in function implementations).
117        - NKSP language: Allow metric unit prefixes of numeric scalar and array
118          variables to be changed freely at runtime (unlike unit types like Hz etc.
119          which are still sticky, parse-time features of variables which cannot be
120          changed at runtime for the intentional sake of determinism).
121        - NKSP language: 'final' values are prohibited for array variables for now
122          (attempt causes a parsers error).
123        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
124          conditions of runtime control structures like if(), while(), select()
125          (attempt causes a parser error).
126        - NKSP VM API: Allow built-in functions to perform their own, individual
127          parse time checks of arguments going to be passed to the function at
128          runtime (added method VMFunction::checkArgs() for that purpose).
129        - NKSP language: raise parser warning if only one operand of binary
130          operators (like logical 'or' comparison) contain a 'final' value (because
131          it would always yield in a 'final' result in such cases).
132        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
133          different metric unit prefixes, which will behave as expected (e.g.
134          result of expression '1000us < 2ms' is true).
135        - NKSP language: Allow adding values with different metric unit prefixes
136          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
137        - NKSP language: Allow subtracting values with different metric unit
138          prefixes (e.g. result of expression '1ms - 20us' is '980us').
139        - NKSP language: Allow multiplying with any metric unit prefixes
140          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
141          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
142          we don't have any considerable practical use for a term like '4s^2'
143          (hence any attempt multiplying two unit types still causes parser error).
144        - NKSP language: Allow dividing by any metric unit prefixes and allow
145          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
146          yields in unit free result '8'). So this is now a way to cast units away
147          e.g. for passing the result to other expressions, certain function calls
148          or variables which are not accepting any units (or that specific unit).
149        - NKSP language: integer arrays and real number arrays can now be converted
150          to strings (e.g. for dumping their content with message() calls for
151          script debugging purposes).
152        - NKSP language: expressions and variables with units are now correctly
153          casted to strings (e.g. with message() calls).
154        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
155          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
156          floating point tolerances into account.
157        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
158          VMScalarNumberExpr::evalCastReal().
159        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
160          'VMIntArrayExpr' and 'VMRealArrayExpr'.
161        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
162          unitFactor() (runtime) methods.
163        - Built-in function "exit()" supports now returning units and 'final'ness
164          for test cases.
165        - The following built-in functions support now units as well: "abs()",
166          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
167          "real_to_int()", "int()", "int_to_real()" and "real()".
168        - Built-in functions "array_equal()", "search()" and "sort()" support now
169          real number arrays (correctly) as well.
170        - Added individual parse time checks of arguments to be passed to built-in
171          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
172          "array_equal()" and "search()" specific for their individual purposes.
173        - NKSP VM refactoring: Renamed all methods, functions and classes matching
174          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
175          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
176          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
177          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
178          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
179          isScalarNumber() -> isNumber()).
180        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
181          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
182          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
183          as convenient methods for automatically converting values to expected
184          metric value basis.
185        - Built-in function "wait()" accepts now both integers and real numbers as
186          argument.
187        - NKSP VM API cleanup: Get rid of legacy method
188          VMFunction::argType(vmint iArg) which was already superseded by its new
189          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
190        - NKSP parser: if wrong argument type was passed to a built-in function and
191          that built-in function accepts more than one data type for the argument,
192          then show all supported data types as parser error message.
193        - Built-in function "play_note()" accepts now real numbers and seconds as
194          unit type as well for its 3rd and 4th function arguments.
195        - The following built-in functions accept now real numbers as well for their
196          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
197          "change_attack()", "change_decay()", "change_release()",
198          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
199          "change_cutoff_sustain()", "change_cutoff_release()",
200          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
201          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
202          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
203        - Fixed built-in function "change_play_pos()" not having accepted metric
204          prefixes at all.
205        - Fixed the following built-in functions having misinterpreted values given
206          with unit type (for their 2nd argument) as if they were relative values
207          (that is as if they were passed without a unit type): "change_attack()",
208          "change_decay()", "change_release()", "change_cutoff_attack()",
209          "change_cutoff_decay()", "change_cutoff_release()".
210        - Fixed the following built-in functions having applied completely wrong
211          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
212          respective EGs being their modulation sink assume uint data type with
213          value range 0..1000 instead of 0.0..1.0.
214        - Added individual parse-time checks of function arguments for the following
215          built-in functions: "play_note()", "note_off()", "set_event_mark()",
216          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
217          "change_decay()", "change_release()", "change_cutoff_attack()",
218          "change_cutoff_decay()", "change_cutoff_release()",
219          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
220          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
221          "change_pan_time()".
222        - Don't abort function call if unit type was used and at the same time
223          'final' operator was omitted for the primary value argument of the
224          following built-in functions: "change_cutoff()", "change_attack()",
225          "change_decay()", "change_release()", "change_cutoff_attack()",
226          "change_cutoff_decay()", "change_cutoff_release()",
227          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
228          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
229          "change_pan_time()", instead imply 'final'ness at runtime and raise an
230          appropriate parser warning at parse time.
231        - Added built-in real number functions "round()", "ceil()", "floor()",
232          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
233          "cos()", "tan()", "asin()", "acos()", "atan()".
234        - Added built-in script real number constant "~NI_MATH_PI".
235        - Added built-in script real number constant "~NI_MATH_E".
236        - NKSP language: Allow unary '+' operator.
237        - Added built-in script functions "msb()" and "lsb()".
238        - NKSP language: Added support for RPN event handler
239          ("on rpn ... end on" in instrument scripts).
240        - NKSP language: Added support for NRPN event handler
241          ("on nrpn ... end on" in instrument scripts).
242        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
243          may be read from the new RPN/NRPN script handlers to get the (N)RPN
244          parameter that had been changed and its new value.
245        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
246          which are identifying the new (N)RPN handlers as such at script runtime.
247        - Implemented built-in script function "set_rpn()".
248        - Implemented built-in script function "set_nrpn()".
249        - Fix: built-in functions returning an array type were broken and caused a
250          crash when the built-in function's (supposed to be array) result value was
251          used by the script VM.
252        - Removed upper value constraint for 2nd argument of built-in functions
253          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
254          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
255          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
256          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
257          the LFO frequency / resonance / cutoff frequency.
258        - Reduced code involved for parsing NKSP variable declarations by using 2
259          generalized grammar rules with optional components (i.e. optional value
260          assignment and optional variable qualifiers) instead of previous linear
261          combinations of grammar rules, which also fixes some edge case.
262        - NKSP language parser: track code block locations also by a) raw byte
263          position in NKSP source code string and b) length of that code block in
264          bytes (along to the already existing code block tracking by line/column);
265          and added appropriate new members to public C++ API classes like
266          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
267        - NKSP language: Added support for 'patch' variable qualifier (capture their
268          locations and allow replacement of their assignment expression via VM C++
269          API).
270        - Fixed incorrect EG times if standard measuring unit was passed to built-in
271          functions "change_attack()", "change_decay()" or "change_release()".
272        - Fixed intermediate function result values never having reflected any
273          standard measuring unit type.
274        - Fixed re-entrant issue with function calls which caused wrong result
275          values if the same function was called multiple times in a term
276          (specifically if metric prefixes were used).
277    
278      * test cases:
279        - Fixed compiler errors in test cases.
280        - Updated README for how to compile & run test cases.
281        - Updated test case
282          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
283          expected behaviour of the Mutex class implementation (recursive
284          mutex type).
285        - Added test cases for NKSP core language aspects and core built-in
286          functions.
287        - Fixed thread tests segfaulting on Linux.
288        - NKSP: Added real number test cases for built-in functions exit(),
289          int_to_real(), real(), real_to_int() and int(), as well as for the
290          plus, minus and negate language operators.
291        - Added massive amount of NKSP test cases for standard measuring units and
292          'final' operator usage cases.
293        - Added NKSP test cases for (floating point tolerance aware) real number
294          equalness / unequalness comparison.
295        - Added NKSP int array and real array tests for value assignment and
296          initialization of arrays.
297        - Added NKSP test cases for built-in functions "round()", "ceil()",
298          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
299          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
300        - Added NKSP test cases for unary '+' operator.
301        - Added NKSP test cases for core built-in variables.
302        - Added thorough NKSP test cases for variable declarations.
303    
304      * GigaStudio/Gigasampler format engine:
305        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
306          behaviour for start_level_mid.
307        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
308          level (see discussion "GigaStudio LFO compatibility" on mailing list
309          from 2019-09-26 for details).
310        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
311          see discussion "GigaStudio LFO compatibility" on mailing list from
312          2019-09-26 for details).
313        - Format extension: Added support for different LFO wave forms (currently
314          either sine [default], triangle, saw or square).
315        - Format extension: Added support for LFO phase displacement (0°..360°).
316        - Format extension: Added support for flipping LFO polarity on LFO 3
317          (in the original gig format this was only available for LFO 1 and LFO 2).
318        - Format extension: Support for additional filter types:
319          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
320          bandreject 2-pole.
321        - Fixd potential crash with polynomial interpolator and max. pitch.
322        - If minimum cutoff is defined, remap cutoff controller CC values to really
323          span the entire possible cutoff range (and avoiding a dead controller
324          zone).
325        - Implemented support for loading instrument scripts with 'patch' variables
326          (by patching these script variables with potentially overridden ones by
327          gig Instrument).
328    
329      * SFZ format engine:
330        - Fixed support for regions with loccN/hiccN conditions on more than one
331          MIDI controller.
332    
333      * Benchmarks:
