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    
42      * Real-time instrument scripts:
43        - Added method ScriptVM::setExitResultEnabled() which allows to
44          explicitly enable the built-in exit() function to optionally accept
45          one function argument; the value of the passed exit() function
46          argument will then become available by calling
47          VMExecContext::exitResult() after script execution.
48        - 64 bit support for NKSP integer scripts variables (declare $foo).
49        - Variable names, function names and preprocessor condition names must start
50          with a regular character (a-z or A-Z); starting them with a digit or
51          underscore is not allowed.
52        - NKSP parser fix: equal comparison operator "=" and not equal comparison
53          operator "#" must only accept integer operands.
54        - NKSP language: Implemented support for standard units like Hertz, seconds,
55          Bel including support for metric unit prefixes; so one can now e.g.
56          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
57          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
58          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
59        - NKSP language: Introduced "final" operator "!" which is specifically
60          intended for synthesis parameter values to denote that the synthesis
61          parameter value is intended to be the "final" value for that synthesis
62          parameter that should explicitly be used by the engine and thus causing
63          the sampler engine to ignore all other modulation sources for the same
64          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
65          variable or formula with this new "!" operator the expression is marked as
66          being "final".
67        - NKSP script editor API: Added support for detecting standard unit tokens
68          and their potential metric prefix token.
69        - NKSP language: Added support for NKSP real number literals and
70          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
71        - NKSP language: Added support for NKSP real number (floating point) script
72          variables (declare ~foo).
73        - NKSP language: Added support for NKSP real number (floating point) array
74          script variables (declare ?foo[]).
75        - Built-in script function "message()" accepts now real number argument as
76          well.
77        - Added built-in script function "real_to_int()" and its short hand form
78          "int()" for casting from real number to integer in NKSP scripts.
79        - Added built-in script function "int_to_real()" and its short hand form
80          "real()" for casting from integer to real number in NKSP scripts.
81        - Allow built-in exit() function to potentially accept real number type
82          argument as well.
83        - Built-in script functions may have a different return type depending on
84          the arguments passed to the function.
85        - Built-in script function "abs()" optionally accepts and returns real
86          number.
87        - Built-in script functions "min()" and "max()" optionally accept real
88          number arguments and return real number as result in that case.
89        - NKSP VM API: Allow units and 'final'ness to be returned as result from
90          built-in functions (added methods VMFunction::returnUnitType() and
91          VMFunction::returnsFinal() for that purpose which must be implemented by
92          built-in function implementations).
93        - NKSP language: Allow metric unit prefixes of numeric scalar and array
94          variables to be changed freely at runtime (unlike unit types like Hz etc.
95          which are still sticky, parse-time features of variables which cannot be
96          changed at runtime for the intentional sake of determinism).
97        - NKSP language: 'final' values are prohibited for array variables for now
98          (attempt causes a parsers error).
99        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
100          conditions of runtime control structures like if(), while(), select()
101          (attempt causes a parser error).
102        - NKSP VM API: Allow built-in functions to perform their own, individual
103          parse time checks of arguments going to be passed to the function at
104          runtime (added method VMFunction::checkArgs() for that purpose).
105        - NKSP language: raise parser warning if only one operand of binary
106          operators (like logical 'or' comparison) contain a 'final' value (because
107          it would always yield in a 'final' result in such cases).
108        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
109          different metric unit prefixes, which will behave as expected (e.g.
110          result of expression '1000us < 2ms' is true).
111        - NKSP language: Allow adding values with different metric unit prefixes
112          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
113        - NKSP language: Allow subtracting values with different metric unit
114          prefixes (e.g. result of expression '1ms - 20us' is '980us').
115        - NKSP language: Allow multiplying with any metric unit prefixes
116          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
117          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
118          we don't have any considerable practical use for a term like '4s^2'
119          (hence any attempt multiplying two unit types still causes parser error).
120        - NKSP language: Allow dividing by any metric unit prefixes and allow
121          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
122          yields in unit free result '8'). So this is now a way to cast units away
123          e.g. for passing the result to other expressions, certain function calls
124          or variables which are not accepting any units (or that specific unit).
125        - NKSP language: integer arrays and real number arrays can now be converted
126          to strings (e.g. for dumping their content with message() calls for
127          script debugging purposes).
128        - NKSP language: expressions and variables with units are now correctly
129          casted to strings (e.g. with message() calls).
130        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
131          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
132          floating point tolerances into account.
133        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
134          VMScalarNumberExpr::evalCastReal().
135        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
136          'VMIntArrayExpr' and 'VMRealArrayExpr'.
137        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
138          unitFactor() (runtime) methods.
139        - Built-in function "exit()" supports now returning units and 'final'ness
140          for test cases.
141        - The following built-in functions support now units as well: "abs()",
142          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
143          "real_to_int()", "int()", "int_to_real()" and "real()".
144        - Built-in functions "array_equal()", "search()" and "sort()" support now
145          real number arrays (correctly) as well.
146        - Added individual parse time checks of arguments to be passed to built-in
147          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
148          "array_equal()" and "search()" specific for their individual purposes.
149        - NKSP VM refactoring: Renamed all methods, functions and classes matching
150          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
151          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
152          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
153          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
154          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
155          isScalarNumber() -> isNumber()).
156        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
157          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
158          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
159          as convenient methods for automatically converting values to expected
160          metric value basis.
161        - Built-in function "wait()" accepts now both integers and real numbers as
162          argument.
163        - NKSP VM API cleanup: Get rid of legacy method
164          VMFunction::argType(vmint iArg) which was already superseded by its new
165          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
166        - NKSP parser: if wrong argument type was passed to a built-in function and
167          that built-in function accepts more than one data type for the argument,
168          then show all supported data types as parser error message.
169        - Built-in function "play_note()" accepts now real numbers and seconds as
170          unit type as well for its 3rd and 4th function arguments.
171        - The following built-in functions accept now real numbers as well for their
172          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
173          "change_attack()", "change_decay()", "change_release()",
174          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
175          "change_cutoff_sustain()", "change_cutoff_release()",
176          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
178          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
179        - Fixed built-in function "change_play_pos()" not having accepted metric
180          prefixes at all.
181        - Fixed the following built-in functions having misinterpreted values given
182          with unit type (for their 2nd argument) as if they were relative values
183          (that is as if they were passed without a unit type): "change_attack()",
184          "change_decay()", "change_release()", "change_cutoff_attack()",
185          "change_cutoff_decay()", "change_cutoff_release()".
186        - Fixed the following built-in functions having applied completely wrong
187          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
188          respective EGs being their modulation sink assume uint data type with
189          value range 0..1000 instead of 0.0..1.0.
190        - Added individual parse-time checks of function arguments for the following
191          built-in functions: "play_note()", "note_off()", "set_event_mark()",
192          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
193          "change_decay()", "change_release()", "change_cutoff_attack()",
194          "change_cutoff_decay()", "change_cutoff_release()",
195          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
196          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
197          "change_pan_time()".
198        - Don't abort function call if unit type was used and at the same time
199          'final' operator was omitted for the primary value argument of the
200          following built-in functions: "change_cutoff()", "change_attack()",
201          "change_decay()", "change_release()", "change_cutoff_attack()",
202          "change_cutoff_decay()", "change_cutoff_release()",
203          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
204          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
205          "change_pan_time()", instead imply 'final'ness at runtime and raise an
206          appropriate parser warning at parse time.
207        - Added built-in real number functions "round()", "ceil()", "floor()",
208          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
209          "cos()", "tan()", "asin()", "acos()", "atan()".
210        - Added built-in script real number constant "~NI_MATH_PI".
211        - Added built-in script real number constant "~NI_MATH_E".
212        - NKSP language: Allow unary '+' operator.
213        - Added built-in script functions "msb()" and "lsb()".
214        - NKSP language: Added support for RPN event handler
215          ("on rpn ... end on" in instrument scripts).
216        - NKSP language: Added support for NRPN event handler
217          ("on nrpn ... end on" in instrument scripts).
218        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
219          may be read from the new RPN/NRPN script handlers to get the (N)RPN
220          parameter that had been changed and its new value.
221        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
222          which are identifying the new (N)RPN handlers as such at script runtime.
223        - Implemented built-in script function "set_rpn()".
224        - Implemented built-in script function "set_nrpn()".
225    
226      * test cases:
227        - Fixed compiler errors in test cases.
228        - Updated README for how to compile & run test cases.
229        - Updated test case
230          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
231          expected behaviour of the Mutex class implementation (recursive
232          mutex type).
233        - Added test cases for NKSP core language aspects and core built-in
234          functions.
235        - Fixed thread tests segfaulting on Linux.
236        - NKSP: Added real number test cases for built-in functions exit(),
237          int_to_real(), real(), real_to_int() and int(), as well as for the
238          plus, minus and negate language operators.
239        - Added massive amount of NKSP test cases for standard measuring units and
240          'final' operator usage cases.
241        - Added NKSP test cases for (floating point tolerance aware) real number
242          equalness / unequalness comparison.
243        - Added NKSP int array and real array tests for value assignment and
244          initialization of arrays.
245        - Added NKSP test cases for built-in functions "round()", "ceil()",
246          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
247          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
248        - Added NKSP test cases for unary '+' operator.
249    
250      * GigaStudio/Gigasampler format engine:
251        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
252          behaviour for start_level_mid.
253        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
254          level (see discussion "GigaStudio LFO compatibility" on mailing list
255          from 2019-09-26 for details).
256        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
257          see discussion "GigaStudio LFO compatibility" on mailing list from
258          2019-09-26 for details).
259        - Format extension: Added support for different LFO wave forms (currently
260          either sine [default], triangle, saw or square).
261        - Format extension: Added support for LFO phase displacement (0°..360°).
262        - Format extension: Added support for flipping LFO polarity on LFO 3
263          (in the original gig format this was only available for LFO 1 and LFO 2).
264        - Format extension: Support for additional filter types:
265          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
266          bandreject 2-pole.
267    
268      * SFZ format engine:
269        - Fixed support for regions with loccN/hiccN conditions on more than one
270          MIDI controller.
271    
272      * Benchmarks:
273        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
274          algorithm (since result of 2nd run was not accumulated).

276        - Added benchmark for sine wave (benchmarks/sine.cpp).
277        - Added benchmark for square wave (benchmarks/square.cpp).
278        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
279          which are large enough on modern systems.
