3    * general changes:    * general changes:
4      - Fixed compiler error in Pool.h.      - Fixed compiler error in Pool.h.
5      - Require C++11 compiler support.      - Require C++14 compiler support.
6      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7        for checking in configure for C++11 support (as mandatory        for checking in configure for C++14 support (as mandatory
8        requirement) and automatically adds compiler argument if required        requirement) and automatically adds compiler argument if required
9        (e.g. -std=C++11).        (e.g. -std=C++14).
10      - RTMath: Implemented floating point comparison methods      - RTMath: Implemented floating point comparison methods
11        fEqual32(float,float) and fEqual64(double,double) which take the        fEqual32(float,float) and fEqual64(double,double) which take the
12        expected floating point tolerances into account.        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    
35    * Real-time instrument scripts:    * Real-time instrument scripts:
36      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to

73        "real()" for casting from integer to real number in NKSP scripts.        "real()" for casting from integer to real number in NKSP scripts.
74      - Allow built-in exit() function to potentially accept real number type      - Allow built-in exit() function to potentially accept real number type
75        argument as well.        argument as well.
76        - Built-in script functions may have a different return type depending on
77          the arguments passed to the function.
78        - Built-in script function "abs()" optionally accepts and returns real
79          number.
80        - Built-in script functions "min()" and "max()" optionally accept real
81          number arguments and return real number as result in that case.
82        - NKSP VM API: Allow units and 'final'ness to be returned as result from
83          built-in functions (added methods VMFunction::returnUnitType() and
84          VMFunction::returnsFinal() for that purpose which must be implemented by
85          built-in function implementations).
86        - NKSP language: Allow metric unit prefixes of numeric scalar and array
87          variables to be changed freely at runtime (unlike unit types like Hz etc.
88          which are still sticky, parse-time features of variables which cannot be
89          changed at runtime for the intentional sake of determinism).
90        - NKSP language: 'final' values are prohibited for array variables for now
91          (attempt causes a parsers error).
92        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
93          conditions of runtime control structures like if(), while(), select()
94          (attempt causes a parser error).
95        - NKSP VM API: Allow built-in functions to perform their own, individual
96          parse time checks of arguments going to be passed to the function at
97          runtime (added method VMFunction::checkArgs() for that purpose).
98        - NKSP language: raise parser warning if only one operand of binary
99          operators (like logical 'or' comparison) contain a 'final' value (because
100          it would always yield in a 'final' result in such cases).
101        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
102          different metric unit prefixes, which will behave as expected (e.g.
103          result of expression '1000us < 2ms' is true).
104        - NKSP language: Allow adding values with different metric unit prefixes
105          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
106        - NKSP language: Allow subtracting values with different metric unit
107          prefixes (e.g. result of expression '1ms - 20us' is '980us').
108        - NKSP language: Allow multiplying with any metric unit prefixes
109          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
110          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
111          we don't have any considerable practical use for a term like '4s^2'
112          (hence any attempt multiplying two unit types still causes parser error).
113        - NKSP language: Allow dividing by any metric unit prefixes and allow
114          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
115          yields in unit free result '8'). So this is now a way to cast units away
116          e.g. for passing the result to other expressions, certain function calls
117          or variables which are not accepting any units (or that specific unit).
118        - NKSP language: integer arrays and real number arrays can now be converted
119          to strings (e.g. for dumping their content with message() calls for
120          script debugging purposes).
121        - NKSP language: expressions and variables with units are now correctly
122          casted to strings (e.g. with message() calls).
123        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
124          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
125          floating point tolerances into account.
126        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
127          VMScalarNumberExpr::evalCastReal().
128        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
129          'VMIntArrayExpr' and 'VMRealArrayExpr'.
130        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
131          unitFactor() (runtime) methods.
132        - Built-in function "exit()" supports now returning units and 'final'ness
133          for test cases.
134        - The following built-in functions support now units as well: "abs()",
135          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
136          "real_to_int()", "int()", "int_to_real()" and "real()".
137        - Built-in functions "array_equal()", "search()" and "sort()" support now
138          real number arrays (correctly) as well.
139        - Added individual parse time checks of arguments to be passed to built-in
140          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
141          "array_equal()" and "search()" specific for their individual purposes.
142        - NKSP VM refactoring: Renamed all methods, functions and classes matching
143          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
144          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
145          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
146          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
147          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
148          isScalarNumber() -> isNumber()).
149        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
150          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
151          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
152          as convenient methods for automatically converting values to expected
153          metric value basis.
154        - Built-in function "wait()" accepts now both integers and real numbers as
155          argument.
156        - NKSP VM API cleanup: Get rid of legacy method
157          VMFunction::argType(vmint iArg) which was already superseded by its new
158          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
159        - NKSP parser: if wrong argument type was passed to a built-in function and
160          that built-in function accepts more than one data type for the argument,
161          then show all supported data types as parser error message.
162        - Built-in function "play_note()" accepts now real numbers and seconds as
163          unit type as well for its 3rd and 4th function arguments.
164        - The following built-in functions accept now real numbers as well for their
165          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
166          "change_attack()", "change_decay()", "change_release()",
167          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
168          "change_cutoff_sustain()", "change_cutoff_release()",
169          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
170          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
171          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
172        - Fixed built-in function "change_play_pos()" not having accepted metric
173          prefixes at all.
174        - Fixed the following built-in functions having misinterpreted values given
175          with unit type (for their 2nd argument) as if they were relative values
176          (that is as if they were passed without a unit type): "change_attack()",
177          "change_decay()", "change_release()", "change_cutoff_attack()",
178          "change_cutoff_decay()", "change_cutoff_release()".
179        - Fixed the following built-in functions having applied completely wrong
180          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
181          respective EGs being their modulation sink assume uint data type with
182          value range 0..1000 instead of 0.0..1.0.
183        - Added individual parse-time checks of function arguments for the following
184          built-in functions: "play_note()", "note_off()", "set_event_mark()",
185          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
186          "change_decay()", "change_release()", "change_cutoff_attack()",
187          "change_cutoff_decay()", "change_cutoff_release()",
188          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
189          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
190          "change_pan_time()".
191        - Don't abort function call if unit type was used and at the same time
192          'final' operator was omitted for the primary value argument of the
193          following built-in functions: "change_cutoff()", "change_attack()",
194          "change_decay()", "change_release()", "change_cutoff_attack()",
195          "change_cutoff_decay()", "change_cutoff_release()",
196          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
197          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
198          "change_pan_time()", instead imply 'final'ness at runtime and raise an
199          appropriate parser warning at parse time.
200        - Added built-in real number functions "round()", "ceil()", "floor()",
201          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
202          "cos()", "tan()", "asin()", "acos()", "atan()".
203        - Added built-in script real number constant "~NI_MATH_PI".
204        - Added built-in script real number constant "~NI_MATH_E".
205        - NKSP language: Allow unary '+' operator.
206        - Added built-in script functions "msb()" and "lsb()".

220        plus, minus and negate language operators.        plus, minus and negate language operators.
221        - Added massive amount of NKSP test cases for standard measuring units and

235        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
236          level (see discussion "GigaStudio LFO compatibility" on mailing list
237          from 2019-09-26 for details).
238        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
239          see discussion "GigaStudio LFO compatibility" on mailing list from
240          2019-09-26 for details).
241        - Format extension: Added support for different LFO wave forms (currently
