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        - Using now cubic interpolation as resampling algorithm by default; and
30          linear interpolation is deprecated now.
31    
32      * Real-time instrument scripts:
33        - Added method ScriptVM::setExitResultEnabled() which allows to
34          explicitly enable the built-in exit() function to optionally accept
35          one function argument; the value of the passed exit() function
36          argument will then become available by calling
37          VMExecContext::exitResult() after script execution.
38        - 64 bit support for NKSP integer scripts variables (declare $foo).
39        - Variable names, function names and preprocessor condition names must start
40          with a regular character (a-z or A-Z); starting them with a digit or
41          underscore is not allowed.
42        - NKSP parser fix: equal comparison operator "=" and not equal comparison
43          operator "#" must only accept integer operands.
44        - NKSP language: Implemented support for standard units like Hertz, seconds,
45          Bel including support for metric unit prefixes; so one can now e.g.
46          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
47          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
48          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
49        - NKSP language: Introduced "final" operator "!" which is specifically
50          intended for synthesis parameter values to denote that the synthesis
51          parameter value is intended to be the "final" value for that synthesis
52          parameter that should explicitly be used by the engine and thus causing
53          the sampler engine to ignore all other modulation sources for the same
54          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
55          variable or formula with this new "!" operator the expression is marked as
56          being "final".
57        - NKSP script editor API: Added support for detecting standard unit tokens
58          and their potential metric prefix token.
59        - NKSP language: Added support for NKSP real number literals and
60          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
61        - NKSP language: Added support for NKSP real number (floating point) script
62          variables (declare ~foo).
63        - NKSP language: Added support for NKSP real number (floating point) array
64          script variables (declare ?foo[]).
65        - Built-in script function "message()" accepts now real number argument as
66          well.
67        - Added built-in script function "real_to_int()" and its short hand form
68          "int()" for casting from real number to integer in NKSP scripts.
69        - Added built-in script function "int_to_real()" and its short hand form
70          "real()" for casting from integer to real number in NKSP scripts.
71        - Allow built-in exit() function to potentially accept real number type
72          argument as well.
73        - Built-in script functions may have a different return type depending on
74          the arguments passed to the function.
75        - Built-in script function "abs()" optionally accepts and returns real
76          number.
77        - Built-in script functions "min()" and "max()" optionally accept real
78          number arguments and return real number as result in that case.
79        - NKSP VM API: Allow units and 'final'ness to be returned as result from
80          built-in functions (added methods VMFunction::returnUnitType() and
81          VMFunction::returnsFinal() for that purpose which must be implemented by
82          built-in function implementations).
83        - NKSP language: Allow metric unit prefixes of numeric scalar and array
84          variables to be changed freely at runtime (unlike unit types like Hz etc.
85          which are still sticky, parse-time features of variables which cannot be
86          changed at runtime for the intentional sake of determinism).
87        - NKSP language: 'final' values are prohibited for array variables for now
88          (attempt causes a parsers error).
89        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
90          conditions of runtime control structures like if(), while(), select()
91          (attempt causes a parser error).
92        - NKSP VM API: Allow built-in functions to perform their own, individual
93          parse time checks of arguments going to be passed to the function at
94          runtime (added method VMFunction::checkArgs() for that purpose).
95        - NKSP language: raise parser warning if only one operand of binary
96          operators (like logical 'or' comparison) contain a 'final' value (because
97          it would always yield in a 'final' result in such cases).
98        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
99          different metric unit prefixes, which will behave as expected (e.g.
100          result of expression '1000us < 2ms' is true).
101        - NKSP language: Allow adding values with different metric unit prefixes
102          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
103        - NKSP language: Allow subtracting values with different metric unit
104          prefixes (e.g. result of expression '1ms - 20us' is '980us').
105        - NKSP language: Allow multiplying with any metric unit prefixes
106          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
107          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
108          we don't have any considerable practical use for a term like '4s^2'
109          (hence any attempt multiplying two unit types still causes parser error).
110        - NKSP language: Allow dividing by any metric unit prefixes and allow
111          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
112          yields in unit free result '8'). So this is now a way to cast units away
113          e.g. for passing the result to other expressions, certain function calls
114          or variables which are not accepting any units (or that specific unit).
115        - NKSP language: integer arrays and real number arrays can now be converted
116          to strings (e.g. for dumping their content with message() calls for
117          script debugging purposes).
118        - NKSP language: expressions and variables with units are now correctly
119          casted to strings (e.g. with message() calls).
120        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
121          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
122          floating point tolerances into account.
123        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
124          VMScalarNumberExpr::evalCastReal().
125        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
126          'VMIntArrayExpr' and 'VMRealArrayExpr'.
127        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
128          unitFactor() (runtime) methods.
129        - Built-in function "exit()" supports now returning units and 'final'ness
130          for test cases.
131        - The following built-in functions support now units as well: "abs()",
132          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
133          "real_to_int()", "int()", "int_to_real()" and "real()".
134        - Built-in functions "array_equal()", "search()" and "sort()" support now
135          real number arrays (correctly) as well.
136        - Added individual parse time checks of arguments to be passed to built-in
137          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
138          "array_equal()" and "search()" specific for their individual purposes.
139        - NKSP VM refactoring: Renamed all methods, functions and classes matching
140          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
141          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
142          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
143          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
144          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
145          isScalarNumber() -> isNumber()).
146        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
147          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
148          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
149          as convenient methods for automatically converting values to expected
150          metric value basis.
151        - Built-in function "wait()" accepts now both integers and real numbers as
152          argument.
153        - NKSP VM API cleanup: Get rid of legacy method
154          VMFunction::argType(vmint iArg) which was already superseded by its new
155          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
156        - NKSP parser: if wrong argument type was passed to a built-in function and
157          that built-in function accepts more than one data type for the argument,
158          then show all supported data types as parser error message.
159        - Built-in function "play_note()" accepts now real numbers and seconds as
160          unit type as well for its 3rd and 4th function arguments.
161        - The following built-in functions accept now real numbers as well for their
162          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
163          "change_attack()", "change_decay()", "change_release()",
164          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
165          "change_cutoff_sustain()", "change_cutoff_release()",
166          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
167          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
168          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
169        - Fixed built-in function "change_play_pos()" not having accepted metric
170          prefixes at all.
171        - Fixed the following built-in functions having misinterpreted values given
172          with unit type (for their 2nd argument) as if they were relative values
173          (that is as if they were passed without a unit type): "change_attack()",
174          "change_decay()", "change_release()", "change_cutoff_attack()",
175          "change_cutoff_decay()", "change_cutoff_release()".
176        - Fixed the following built-in functions having applied completely wrong
177          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
178          respective EGs being their modulation sink assume uint data type with
179          value range 0..1000 instead of 0.0..1.0.
180        - Added individual parse-time checks of function arguments for the following
181          built-in functions: "play_note()", "note_off()", "set_event_mark()",
182          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
183          "change_decay()", "change_release()", "change_cutoff_attack()",
184          "change_cutoff_decay()", "change_cutoff_release()",
185          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
187          "change_pan_time()".
188        - Don't abort function call if unit type was used and at the same time
189          'final' operator was omitted for the primary value argument of the
190          following built-in functions: "change_cutoff()", "change_attack()",
191          "change_decay()", "change_release()", "change_cutoff_attack()",
192          "change_cutoff_decay()", "change_cutoff_release()",
193          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
194          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
195          "change_pan_time()", instead imply 'final'ness at runtime and raise an
196          appropriate parser warning at parse time.
197        - Added built-in real number functions "round()", "ceil()", "floor()",
198          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
199          "cos()", "tan()", "asin()", "acos()", "atan()".
200        - Added built-in script real number constant "~NI_MATH_PI".
201        - Added built-in script real number constant "~NI_MATH_E".
202        - NKSP language: Allow unary '+' operator.
203        - Added built-in script functions "msb()" and "lsb()".
204    
205      * test cases:
206        - Fixed compiler errors in test cases.
207        - Updated README for how to compile & run test cases.
208        - Updated test case
209          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
210          expected behaviour of the Mutex class implementation (recursive
211          mutex type).
212        - Added test cases for NKSP core language aspects and core built-in
213          functions.
214        - Fixed thread tests segfaulting on Linux.
215        - NKSP: Added real number test cases for built-in functions exit(),
216          int_to_real(), real(), real_to_int() and int(), as well as for the
217          plus, minus and negate language operators.
218        - Added massive amount of NKSP test cases for standard measuring units and
219          'final' operator usage cases.
220        - Added NKSP test cases for (floating point tolerance aware) real number
221          equalness / unequalness comparison.
222        - Added NKSP int array and real array tests for value assignment and
223          initialization of arrays.
224        - Added NKSP test cases for built-in functions "round()", "ceil()",
225          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
226          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
227        - Added NKSP test cases for unary '+' operator.
228    
229      * GigaStudio/Gigasampler format engine:
230        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
231          behaviour for start_level_mid.
232        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
233          level (see discussion "GigaStudio LFO compatibility" on mailing list
234          from 2019-09-26 for details).
235        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
236          see discussion "GigaStudio LFO compatibility" on mailing list from
237          2019-09-26 for details).
238        - Format extension: Added support for different LFO wave forms (currently
239          either sine [default], triangle, saw or square).
240        - Format extension: Added support for LFO phase displacement (0°..360°).
241        - Format extension: Added support for flipping LFO polarity on LFO 3
242          (in the original gig format this was only available for LFO 1 and LFO 2).

246    
247      * SFZ format engine:
248        - Fixed support for regions with loccN/hiccN conditions on more than one
249          MIDI controller.
250    
251      * Benchmarks:
252        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
253          algorithm (since result of 2nd run was not accumulated).
254        - Added benchmark for saw wave (benchmarks/saw.cpp).
255        - Added benchmark for sine wave (benchmarks/sine.cpp).
256        - Added benchmark for square wave (benchmarks/square.cpp).
257        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
258          which are large enough on modern systems.
259    
260    Version 2.1.1 (27 Jul 2019)
261    
262      * Real-time instrument scripts:
263        - Fixed behavior of built-in NKSP functions change_sustain(),
264          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
265          and change_cutoff_release().
266    
267      * general changes:
268        - Only play release trigger samples on sustain pedal up if this behaviour
269          was explicitly requested by the instrument (otherwise only on note-off).
270        - Fixed compiler warnings.
271        - Fixed compilation error when cross-compiling to Mac.
272        - FX Sends: Provide more useful error messages on routing problems

275          of using external vs. internal effects (see bug #169).
276        - "optional" class: Fixed comparison operators.
277    
278      * Gigasampler/GigaStudio format engine:

283        - Fixed memory leak when releasing samples
284          (fixes bug #307, patch by Jacek Roszkowski)
285        - Fixed potential crash when a sample is shared by more than one region
286          (fixes bug #308, patch by Jacek Roszkowski).

304        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
305          all if an up-pitch of more than 40 semi tones was requested (I don't
306          think there is any stock gig sound that requires this behavior to
307          resemble its original sound).
308        - Added support for controlling whether the individual EGADSR stages may
309          be aborted (as LinuxSampler extension to the original GigaStudio 4
