3    * general changes:    * general changes:
4      - Fixed compiler error in Pool.h.      - 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.

51    * Real-time instrument scripts:    * Real-time instrument scripts:
52      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to

56        VMExecContext::exitResult() after script execution.        VMExecContext::exitResult() after script execution.
57        - 64 bit support for NKSP integer scripts variables (declare $foo).
58        - Variable names, function names and preprocessor condition names must start
59          with a regular character (a-z or A-Z); starting them with a digit or
60          underscore is not allowed.
61        - NKSP parser fix: equal comparison operator "=" and not equal comparison
62          operator "#" must only accept integer operands.
63        - NKSP language: Implemented support for standard units like Hertz, seconds,
64          Bel including support for metric unit prefixes; so one can now e.g.
65          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
66          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
67          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
68        - NKSP language: Introduced "final" operator "!" which is specifically
69          intended for synthesis parameter values to denote that the synthesis
70          parameter value is intended to be the "final" value for that synthesis
71          parameter that should explicitly be used by the engine and thus causing
72          the sampler engine to ignore all other modulation sources for the same
73          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
74          variable or formula with this new "!" operator the expression is marked as
75          being "final".
76        - NKSP script editor API: Added support for detecting standard unit tokens
77          and their potential metric prefix token.
78        - NKSP language: Added support for NKSP real number literals and
79          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
80        - NKSP language: Added support for NKSP real number (floating point) script
81          variables (declare ~foo).
82        - NKSP language: Added support for NKSP real number (floating point) array
83          script variables (declare ?foo[]).
84        - Built-in script function "message()" accepts now real number argument as
85          well.
86        - Added built-in script function "real_to_int()" and its short hand form
87          "int()" for casting from real number to integer in NKSP scripts.
88        - Added built-in script function "int_to_real()" and its short hand form
89          "real()" for casting from integer to real number in NKSP scripts.
90        - Allow built-in exit() function to potentially accept real number type
91          argument as well.
92        - Built-in script functions may have a different return type depending on
93          the arguments passed to the function.
94        - Built-in script function "abs()" optionally accepts and returns real
95          number.
96        - Built-in script functions "min()" and "max()" optionally accept real
97          number arguments and return real number as result in that case.
98        - NKSP VM API: Allow units and 'final'ness to be returned as result from
99          built-in functions (added methods VMFunction::returnUnitType() and
100          VMFunction::returnsFinal() for that purpose which must be implemented by
101          built-in function implementations).
102        - NKSP language: Allow metric unit prefixes of numeric scalar and array
103          variables to be changed freely at runtime (unlike unit types like Hz etc.
104          which are still sticky, parse-time features of variables which cannot be
105          changed at runtime for the intentional sake of determinism).
106        - NKSP language: 'final' values are prohibited for array variables for now
107          (attempt causes a parsers error).
108        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
109          conditions of runtime control structures like if(), while(), select()
110          (attempt causes a parser error).
111        - NKSP VM API: Allow built-in functions to perform their own, individual
112          parse time checks of arguments going to be passed to the function at
113          runtime (added method VMFunction::checkArgs() for that purpose).
114        - NKSP language: raise parser warning if only one operand of binary
115          operators (like logical 'or' comparison) contain a 'final' value (because
116          it would always yield in a 'final' result in such cases).
117        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
118          different metric unit prefixes, which will behave as expected (e.g.
119          result of expression '1000us < 2ms' is true).
120        - NKSP language: Allow adding values with different metric unit prefixes
121          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
122        - NKSP language: Allow subtracting values with different metric unit
123          prefixes (e.g. result of expression '1ms - 20us' is '980us').
124        - NKSP language: Allow multiplying with any metric unit prefixes
125          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
126          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
127          we don't have any considerable practical use for a term like '4s^2'
128          (hence any attempt multiplying two unit types still causes parser error).
129        - NKSP language: Allow dividing by any metric unit prefixes and allow
130          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
131          yields in unit free result '8'). So this is now a way to cast units away
132          e.g. for passing the result to other expressions, certain function calls
133          or variables which are not accepting any units (or that specific unit).
134        - NKSP language: integer arrays and real number arrays can now be converted
135          to strings (e.g. for dumping their content with message() calls for
136          script debugging purposes).
137        - NKSP language: expressions and variables with units are now correctly
138          casted to strings (e.g. with message() calls).
139        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
140          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
141          floating point tolerances into account.
142        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
143          VMScalarNumberExpr::evalCastReal().
144        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
145          'VMIntArrayExpr' and 'VMRealArrayExpr'.
146        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
147          unitFactor() (runtime) methods.
148        - Built-in function "exit()" supports now returning units and 'final'ness
149          for test cases.
150        - The following built-in functions support now units as well: "abs()",
151          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
152          "real_to_int()", "int()", "int_to_real()" and "real()".
153        - Built-in functions "array_equal()", "search()" and "sort()" support now
154          real number arrays (correctly) as well.
155        - Added individual parse time checks of arguments to be passed to built-in
156          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
157          "array_equal()" and "search()" specific for their individual purposes.
158        - NKSP VM refactoring: Renamed all methods, functions and classes matching
159          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
160          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
161          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
162          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
163          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
164          isScalarNumber() -> isNumber()).
165        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
166          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
167          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
168          as convenient methods for automatically converting values to expected
169          metric value basis.
170        - Built-in function "wait()" accepts now both integers and real numbers as
171          argument.
172        - NKSP VM API cleanup: Get rid of legacy method
173          VMFunction::argType(vmint iArg) which was already superseded by its new
174          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
175        - NKSP parser: if wrong argument type was passed to a built-in function and
176          that built-in function accepts more than one data type for the argument,
177          then show all supported data types as parser error message.
178        - Built-in function "play_note()" accepts now real numbers and seconds as
179          unit type as well for its 3rd and 4th function arguments.
180        - The following built-in functions accept now real numbers as well for their
181          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
182          "change_attack()", "change_decay()", "change_release()",
183          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
184          "change_cutoff_sustain()", "change_cutoff_release()",
185          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
187          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
188        - Fixed built-in function "change_play_pos()" not having accepted metric
189          prefixes at all.
190        - Fixed the following built-in functions having misinterpreted values given
191          with unit type (for their 2nd argument) as if they were relative values
192          (that is as if they were passed without a unit type): "change_attack()",
193          "change_decay()", "change_release()", "change_cutoff_attack()",
194          "change_cutoff_decay()", "change_cutoff_release()".
195        - Fixed the following built-in functions having applied completely wrong
196          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
197          respective EGs being their modulation sink assume uint data type with
198          value range 0..1000 instead of 0.0..1.0.
199        - Added individual parse-time checks of function arguments for the following
200          built-in functions: "play_note()", "note_off()", "set_event_mark()",
201          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
202          "change_decay()", "change_release()", "change_cutoff_attack()",
203          "change_cutoff_decay()", "change_cutoff_release()",
204          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
205          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
206          "change_pan_time()".
207        - Don't abort function call if unit type was used and at the same time
208          'final' operator was omitted for the primary value argument of the
209          following built-in functions: "change_cutoff()", "change_attack()",
210          "change_decay()", "change_release()", "change_cutoff_attack()",
211          "change_cutoff_decay()", "change_cutoff_release()",
212          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
213          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
214          "change_pan_time()", instead imply 'final'ness at runtime and raise an
215          appropriate parser warning at parse time.
216        - Added built-in real number functions "round()", "ceil()", "floor()",
217          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
218          "cos()", "tan()", "asin()", "acos()", "atan()".
219        - Added built-in script real number constant "~NI_MATH_PI".
220        - Added built-in script real number constant "~NI_MATH_E".
221        - NKSP language: Allow unary '+' operator.
222        - Added built-in script functions "msb()" and "lsb()".
223        - NKSP language: Added support for RPN event handler
224          ("on rpn ... end on" in instrument scripts).
225        - NKSP language: Added support for NRPN event handler
226          ("on nrpn ... end on" in instrument scripts).
227        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
228          may be read from the new RPN/NRPN script handlers to get the (N)RPN
229          parameter that had been changed and its new value.
230        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
231          which are identifying the new (N)RPN handlers as such at script runtime.
232        - Implemented built-in script function "set_rpn()".
233        - Implemented built-in script function "set_nrpn()".
234        - Fix: built-in functions returning an array type were broken and caused a
235          crash when the built-in function's (supposed to be array) result value was
236          used by the script VM.
237        - Removed upper value constraint for 2nd argument of built-in functions
238          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
239          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
240          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
241          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
242          the LFO frequency / resonance / cutoff frequency.

271          behaviour for start_level_mid.
272        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
273          level (see discussion "GigaStudio LFO compatibility" on mailing list
274          from 2019-09-26 for details).
275        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
276          see discussion "GigaStudio LFO compatibility" on mailing list from
277          2019-09-26 for details).
