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        - 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.
50        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51          instrument editor.
52        - Fixed playing noise at the end of a disk stream under certain conditions.
53    
54      * Real-time instrument scripts:
55        - Added method ScriptVM::setExitResultEnabled() which allows to
56          explicitly enable the built-in exit() function to optionally accept
57          one function argument; the value of the passed exit() function
58          argument will then become available by calling
59          VMExecContext::exitResult() after script execution.
60        - 64 bit support for NKSP integer scripts variables (declare $foo).
61        - Variable names, function names and preprocessor condition names must start
62          with a regular character (a-z or A-Z); starting them with a digit or
63          underscore is not allowed.
64        - NKSP parser fix: equal comparison operator "=" and not equal comparison
65          operator "#" must only accept integer operands.
66        - NKSP language: Implemented support for standard units like Hertz, seconds,
67          Bel including support for metric unit prefixes; so one can now e.g.
68          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
69          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
70          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
71        - NKSP language: Introduced "final" operator "!" which is specifically
72          intended for synthesis parameter values to denote that the synthesis
73          parameter value is intended to be the "final" value for that synthesis
74          parameter that should explicitly be used by the engine and thus causing
75          the sampler engine to ignore all other modulation sources for the same
76          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
77          variable or formula with this new "!" operator the expression is marked as
78          being "final".
79        - NKSP script editor API: Added support for detecting standard unit tokens
80          and their potential metric prefix token.
81        - NKSP language: Added support for NKSP real number literals and
82          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
83        - NKSP language: Added support for NKSP real number (floating point) script
84          variables (declare ~foo).
85        - NKSP language: Added support for NKSP real number (floating point) array
86          script variables (declare ?foo[]).
87        - Built-in script function "message()" accepts now real number argument as
88          well.
89        - Added built-in script function "real_to_int()" and its short hand form
90          "int()" for casting from real number to integer in NKSP scripts.
91        - Added built-in script function "int_to_real()" and its short hand form
92          "real()" for casting from integer to real number in NKSP scripts.
93        - Allow built-in exit() function to potentially accept real number type
94          argument as well.
95        - Built-in script functions may have a different return type depending on
96          the arguments passed to the function.
97        - Built-in script function "abs()" optionally accepts and returns real
98          number.
99        - Built-in script functions "min()" and "max()" optionally accept real
100          number arguments and return real number as result in that case.
101        - NKSP VM API: Allow units and 'final'ness to be returned as result from
102          built-in functions (added methods VMFunction::returnUnitType() and
103          VMFunction::returnsFinal() for that purpose which must be implemented by
104          built-in function implementations).
105        - NKSP language: Allow metric unit prefixes of numeric scalar and array
106          variables to be changed freely at runtime (unlike unit types like Hz etc.
107          which are still sticky, parse-time features of variables which cannot be
108          changed at runtime for the intentional sake of determinism).
109        - NKSP language: 'final' values are prohibited for array variables for now
110          (attempt causes a parsers error).
111        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
112          conditions of runtime control structures like if(), while(), select()
113          (attempt causes a parser error).
114        - NKSP VM API: Allow built-in functions to perform their own, individual
115          parse time checks of arguments going to be passed to the function at
116          runtime (added method VMFunction::checkArgs() for that purpose).
117        - NKSP language: raise parser warning if only one operand of binary
118          operators (like logical 'or' comparison) contain a 'final' value (because
119          it would always yield in a 'final' result in such cases).
120        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
121          different metric unit prefixes, which will behave as expected (e.g.
122          result of expression '1000us < 2ms' is true).
123        - NKSP language: Allow adding values with different metric unit prefixes
124          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
125        - NKSP language: Allow subtracting values with different metric unit
126          prefixes (e.g. result of expression '1ms - 20us' is '980us').
127        - NKSP language: Allow multiplying with any metric unit prefixes
128          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
129          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
130          we don't have any considerable practical use for a term like '4s^2'
131          (hence any attempt multiplying two unit types still causes parser error).
132        - NKSP language: Allow dividing by any metric unit prefixes and allow
133          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
134          yields in unit free result '8'). So this is now a way to cast units away
135          e.g. for passing the result to other expressions, certain function calls
136          or variables which are not accepting any units (or that specific unit).
137        - NKSP language: integer arrays and real number arrays can now be converted
138          to strings (e.g. for dumping their content with message() calls for
139          script debugging purposes).
140        - NKSP language: expressions and variables with units are now correctly
141          casted to strings (e.g. with message() calls).
142        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
143          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
144          floating point tolerances into account.
145        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
146          VMScalarNumberExpr::evalCastReal().
147        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
148          'VMIntArrayExpr' and 'VMRealArrayExpr'.
149        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
150          unitFactor() (runtime) methods.
151        - Built-in function "exit()" supports now returning units and 'final'ness
152          for test cases.
153        - The following built-in functions support now units as well: "abs()",
154          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
155          "real_to_int()", "int()", "int_to_real()" and "real()".
156        - Built-in functions "array_equal()", "search()" and "sort()" support now
157          real number arrays (correctly) as well.
158        - Added individual parse time checks of arguments to be passed to built-in
159          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
160          "array_equal()" and "search()" specific for their individual purposes.
161        - NKSP VM refactoring: Renamed all methods, functions and classes matching
162          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
163          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
164          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
165          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
166          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
167          isScalarNumber() -> isNumber()).
168        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
169          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
170          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
171          as convenient methods for automatically converting values to expected
172          metric value basis.
173        - Built-in function "wait()" accepts now both integers and real numbers as
174          argument.
175        - NKSP VM API cleanup: Get rid of legacy method
176          VMFunction::argType(vmint iArg) which was already superseded by its new
177          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
178        - NKSP parser: if wrong argument type was passed to a built-in function and
179          that built-in function accepts more than one data type for the argument,
180          then show all supported data types as parser error message.
181        - Built-in function "play_note()" accepts now real numbers and seconds as
182          unit type as well for its 3rd and 4th function arguments.
183        - The following built-in functions accept now real numbers as well for their
184          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
185          "change_attack()", "change_decay()", "change_release()",
186          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
187          "change_cutoff_sustain()", "change_cutoff_release()",
188          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
189          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
190          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
191        - Fixed built-in function "change_play_pos()" not having accepted metric
192          prefixes at all.
193        - Fixed the following built-in functions having misinterpreted values given
194          with unit type (for their 2nd argument) as if they were relative values
195          (that is as if they were passed without a unit type): "change_attack()",
196          "change_decay()", "change_release()", "change_cutoff_attack()",
197          "change_cutoff_decay()", "change_cutoff_release()".
198        - Fixed the following built-in functions having applied completely wrong
199          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
200          respective EGs being their modulation sink assume uint data type with
201          value range 0..1000 instead of 0.0..1.0.
202        - Added individual parse-time checks of function arguments for the following
203          built-in functions: "play_note()", "note_off()", "set_event_mark()",
204          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
205          "change_decay()", "change_release()", "change_cutoff_attack()",
206          "change_cutoff_decay()", "change_cutoff_release()",
207          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
208          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
209          "change_pan_time()".
210        - Don't abort function call if unit type was used and at the same time
211          'final' operator was omitted for the primary value argument of the
212          following built-in functions: "change_cutoff()", "change_attack()",
213          "change_decay()", "change_release()", "change_cutoff_attack()",
214          "change_cutoff_decay()", "change_cutoff_release()",
215          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
216          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
217          "change_pan_time()", instead imply 'final'ness at runtime and raise an
218          appropriate parser warning at parse time.
219        - Added built-in real number functions "round()", "ceil()", "floor()",
220          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
221          "cos()", "tan()", "asin()", "acos()", "atan()".
222        - Added built-in script real number constant "~NI_MATH_PI".
223        - Added built-in script real number constant "~NI_MATH_E".
224        - NKSP language: Allow unary '+' operator.
225        - Added built-in script functions "msb()" and "lsb()".
226        - NKSP language: Added support for RPN event handler
227          ("on rpn ... end on" in instrument scripts).
228        - NKSP language: Added support for NRPN event handler
229          ("on nrpn ... end on" in instrument scripts).
230        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
231          may be read from the new RPN/NRPN script handlers to get the (N)RPN
232          parameter that had been changed and its new value.
233        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
234          which are identifying the new (N)RPN handlers as such at script runtime.
235        - Implemented built-in script function "set_rpn()".
236        - Implemented built-in script function "set_nrpn()".
237        - Fix: built-in functions returning an array type were broken and caused a
238          crash when the built-in function's (supposed to be array) result value was
239          used by the script VM.
240        - Removed upper value constraint for 2nd argument of built-in functions
241          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
242          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
243          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
244          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
245          the LFO frequency / resonance / cutoff frequency.
246    
247      * test cases:
248        - Fixed compiler errors in test cases.
249        - Updated README for how to compile & run test cases.
250        - Updated test case
251          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
252          expected behaviour of the Mutex class implementation (recursive
253          mutex type).
254        - Added test cases for NKSP core language aspects and core built-in
255          functions.
256        - Fixed thread tests segfaulting on Linux.
257        - NKSP: Added real number test cases for built-in functions exit(),
258          int_to_real(), real(), real_to_int() and int(), as well as for the
259          plus, minus and negate language operators.
260        - Added massive amount of NKSP test cases for standard measuring units and
261          'final' operator usage cases.
262        - Added NKSP test cases for (floating point tolerance aware) real number
263          equalness / unequalness comparison.
264        - Added NKSP int array and real array tests for value assignment and
265          initialization of arrays.
266        - Added NKSP test cases for built-in functions "round()", "ceil()",
267          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
268          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
269        - Added NKSP test cases for unary '+' operator.
270        - Added NKSP test cases for core built-in variables.
271    
272      * GigaStudio/Gigasampler format engine:
273        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
274          behaviour for start_level_mid.
275        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
276          level (see discussion "GigaStudio LFO compatibility" on mailing list
277          from 2019-09-26 for details).
278        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
279          see discussion "GigaStudio LFO compatibility" on mailing list from
280          2019-09-26 for details).
281        - Format extension: Added support for different LFO wave forms (currently
282          either sine [default], triangle, saw or square).
283        - Format extension: Added support for LFO phase displacement (0°..360°).
284        - Format extension: Added support for flipping LFO polarity on LFO 3
285          (in the original gig format this was only available for LFO 1 and LFO 2).
286        - Format extension: Support for additional filter types:
287          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
288          bandreject 2-pole.
289        - Fixd potential crash with polynomial interpolator and max. pitch.
290        - If minimum cutoff is defined, remap cutoff controller CC values to really
291          span the entire possible cutoff range (and avoiding a dead controller
292          zone).
293    
294      * SFZ format engine:
295        - Fixed support for regions with loccN/hiccN conditions on more than one
296          MIDI controller.
297    
298      * Benchmarks:
299        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
300          algorithm (since result of 2nd run was not accumulated).
301        - Added benchmark for saw wave (benchmarks/saw.cpp).
302        - Added benchmark for sine wave (benchmarks/sine.cpp).
303        - Added benchmark for square wave (benchmarks/square.cpp).
304        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
305          which are large enough on modern systems.
306    
307    Version 2.1.1 (27 Jul 2019)
308    
309      * Real-time instrument scripts:
310        - Fixed behavior of built-in NKSP functions change_sustain(),
311          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
312          and change_cutoff_release().
313    
314      * general changes:
315        - Only play release trigger samples on sustain pedal up if this behaviour
316          was explicitly requested by the instrument (otherwise only on note-off).
317        - Fixed compiler warnings.
318        - Fixed compilation error when cross-compiling to Mac.
319        - FX Sends: Provide more useful error messages on routing problems
320          (see bug #169).
321        - LSCP doc: Be more clear describing the two distinct approaches
322          of using external vs. internal effects (see bug #169).
323        - "optional" class: Fixed comparison operators.
324    
325      * Gigasampler/GigaStudio format engine:
326        - Format extension: If requested by instrument then don't play release
327          trigger sample on note-off events.
328    
329      * SFZ format engine:
330        - Fixed memory leak when releasing samples
331          (fixes bug #307, patch by Jacek Roszkowski)
332        - Fixed potential crash when a sample is shared by more than one region
333          (fixes bug #308, patch by Jacek Roszkowski).
334        - Opcode 'sample': Added support for built-in sample '*silence'
335          (fixes bug #310, patch by Jacek Roszkowski).
336    
337    Version 2.1.0 (25 Nov 2017)
