1  Version SVN trunk (?)  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    
30      * Real-time instrument scripts:
31        - Added method ScriptVM::setExitResultEnabled() which allows to
32          explicitly enable the built-in exit() function to optionally accept
33          one function argument; the value of the passed exit() function
34          argument will then become available by calling
35          VMExecContext::exitResult() after script execution.
36        - 64 bit support for NKSP integer scripts variables (declare $foo).
37        - Variable names, function names and preprocessor condition names must start
38          with a regular character (a-z or A-Z); starting them with a digit or
39          underscore is not allowed.
40        - NKSP parser fix: equal comparison operator "=" and not equal comparison
41          operator "#" must only accept integer operands.
42        - NKSP language: Implemented support for standard units like Hertz, seconds,
43          Bel including support for metric unit prefixes; so one can now e.g.
44          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
45          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
46          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
47        - NKSP language: Introduced "final" operator "!" which is specifically
48          intended for synthesis parameter values to denote that the synthesis
49          parameter value is intended to be the "final" value for that synthesis
50          parameter that should explicitly be used by the engine and thus causing
51          the sampler engine to ignore all other modulation sources for the same
52          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
53          variable or formula with this new "!" operator the expression is marked as
54          being "final".
55        - NKSP script editor API: Added support for detecting standard unit tokens
56          and their potential metric prefix token.
57        - NKSP language: Added support for NKSP real number literals and
58          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
59        - NKSP language: Added support for NKSP real number (floating point) script
60          variables (declare ~foo).
61        - NKSP language: Added support for NKSP real number (floating point) array
62          script variables (declare ?foo[]).
63        - Built-in script function "message()" accepts now real number argument as
64          well.
65        - Added built-in script function "real_to_int()" and its short hand form
66          "int()" for casting from real number to integer in NKSP scripts.
67        - Added built-in script function "int_to_real()" and its short hand form
68          "real()" for casting from integer to real number in NKSP scripts.
69        - Allow built-in exit() function to potentially accept real number type
70          argument as well.
71        - Built-in script functions may have a different return type depending on
72          the arguments passed to the function.
73        - Built-in script function "abs()" optionally accepts and returns real
74          number.
75        - Built-in script functions "min()" and "max()" optionally accept real
76          number arguments and return real number as result in that case.
77        - NKSP VM API: Allow units and 'final'ness to be returned as result from
78          built-in functions (added methods VMFunction::returnUnitType() and
79          VMFunction::returnsFinal() for that purpose which must be implemented by
80          built-in function implementations).
81        - NKSP language: Allow metric unit prefixes of numeric scalar and array
82          variables to be changed freely at runtime (unlike unit types like Hz etc.
83          which are still sticky, parse-time features of variables which cannot be
84          changed at runtime for the intentional sake of determinism).
85        - NKSP language: 'final' values are prohibited for array variables for now
86          (attempt causes a parsers error).
87        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
88          conditions of runtime control structures like if(), while(), select()
89          (attempt causes a parser error).
90        - NKSP VM API: Allow built-in functions to perform their own, individual
91          parse time checks of arguments going to be passed to the function at
92          runtime (added method VMFunction::checkArgs() for that purpose).
93        - NKSP language: raise parser warning if only one operand of binary
94          operators (like logical 'or' comparison) contain a 'final' value (because
95          it would always yield in a 'final' result in such cases).
96        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
97          different metric unit prefixes, which will behave as expected (e.g.
98          result of expression '1000us < 2ms' is true).
99        - NKSP language: Allow adding values with different metric unit prefixes
100          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
101        - NKSP language: Allow subtracting values with different metric unit
102          prefixes (e.g. result of expression '1ms - 20us' is '980us').
103        - NKSP language: Allow multiplying with any metric unit prefixes
104          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
105          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
106          we don't have any considerable practical use for a term like '4s^2'
107          (hence any attempt multiplying two unit types still causes parser error).
108        - NKSP language: Allow dividing by any metric unit prefixes and allow
109          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
110          yields in unit free result '8'). So this is now a way to cast units away
111          e.g. for passing the result to other expressions, certain function calls
112          or variables which are not accepting any units (or that specific unit).
113        - NKSP language: integer arrays and real number arrays can now be converted
114          to strings (e.g. for dumping their content with message() calls for
115          script debugging purposes).
116        - NKSP language: expressions and variables with units are now correctly
117          casted to strings (e.g. with message() calls).
118        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
119          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
120          floating point tolerances into account.
121        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
122          VMScalarNumberExpr::evalCastReal().
123        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
124          'VMIntArrayExpr' and 'VMRealArrayExpr'.
125        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
126          unitFactor() (runtime) methods.
127        - Built-in function "exit()" supports now returning units and 'final'ness
128          for test cases.
129        - The following built-in functions support now units as well: "abs()",
130          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
131          "real_to_int()", "int()", "int_to_real()" and "real()".
132        - Built-in functions "array_equal()", "search()" and "sort()" support now
133          real number arrays (correctly) as well.
134        - Added individual parse time checks of arguments to be passed to built-in
135          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
136          "array_equal()" and "search()" specific for their individual purposes.
137        - NKSP VM refactoring: Renamed all methods, functions and classes matching
138          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
139          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
140          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
141          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
142          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
143          isScalarNumber() -> isNumber()).
144        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
145          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
146          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
147          as convenient methods for automatically converting values to expected
148          metric value basis.
149        - Built-in function "wait()" accepts now both integers and real numbers as
150          argument.
151        - NKSP VM API cleanup: Get rid of legacy method
152          VMFunction::argType(vmint iArg) which was already superseded by its new
153          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
154        - NKSP parser: if wrong argument type was passed to a built-in function and
155          that built-in function accepts more than one data type for the argument,
156          then show all supported data types as parser error message.
157        - Built-in function "play_note()" accepts now real numbers and seconds as
158          unit type as well for its 3rd and 4th function arguments.
159        - The following built-in functions accept now real numbers as well for their
160          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
161          "change_attack()", "change_decay()", "change_release()",
162          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
163          "change_cutoff_sustain()", "change_cutoff_release()",
164          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
165          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
166          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
167        - Fixed built-in function "change_play_pos()" not having accepted metric
168          prefixes at all.
169        - Fixed the following built-in functions having misinterpreted values given
170          with unit type (for their 2nd argument) as if they were relative values
171          (that is as if they were passed without a unit type): "change_attack()",
172          "change_decay()", "change_release()", "change_cutoff_attack()",
173          "change_cutoff_decay()", "change_cutoff_release()".
174        - Fixed the following built-in functions having applied completely wrong
175          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
176          respective EGs being their modulation sink assume uint data type with
177          value range 0..1000 instead of 0.0..1.0.
178        - Added individual parse-time checks of function arguments for the following
179          built-in functions: "play_note()", "note_off()", "set_event_mark()",
180          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
181          "change_decay()", "change_release()", "change_cutoff_attack()",
182          "change_cutoff_decay()", "change_cutoff_release()",
183          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
184          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
185          "change_pan_time()".
186        - Don't abort function call if unit type was used and at the same time
187          'final' operator was omitted for the primary value argument of the
188          following built-in functions: "change_cutoff()", "change_attack()",
189          "change_decay()", "change_release()", "change_cutoff_attack()",
190          "change_cutoff_decay()", "change_cutoff_release()",
191          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
192          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
193          "change_pan_time()", instead imply 'final'ness at runtime and raise an
194          appropriate parser warning at parse time.
195        - Added built-in real number functions "round()", "ceil()", "floor()",
196          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
197          "cos()", "tan()", "asin()", "acos()", "atan()".
198        - Added built-in script real number constant "~NI_MATH_PI".
199        - Added built-in script real number constant "~NI_MATH_E".

209        - Added test cases for NKSP core language aspects and core built-in
210          functions.
211        - Fixed thread tests segfaulting on Linux.
212        - NKSP: Added real number test cases for built-in functions exit(),
213          int_to_real(), real(), real_to_int() and int(), as well as for the
214          plus, minus and negate language operators.
215        - Added massive amount of NKSP test cases for standard measuring units and
216          'final' operator usage cases.
217        - Added NKSP test cases for (floating point tolerance aware) real number
218          equalness / unequalness comparison.
219        - Added NKSP int array and real array tests for value assignment and
220          initialization of arrays.
221        - Added NKSP test cases for built-in functions "round()", "ceil()",
222          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",

232          MIDI controller.
233    
234      * Benchmarks:
235        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
236          algorithm (since result of 2nd run was not accumulated).
237        - Added benchmark for saw wave (benchmarks/saw.cpp).
238        - Added benchmark for sine wave (benchmarks/sine.cpp).
239        - Added benchmark for square wave (benchmarks/square.cpp).
240        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
241          which are large enough on modern systems.
