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

191          expected behaviour of the Mutex class implementation (recursive
192          mutex type).
193        - Added test cases for NKSP core language aspects and core built-in
194          functions.
195        - Fixed thread tests segfaulting on Linux.
196        - NKSP: Added real number test cases for built-in functions exit(),
197          int_to_real(), real(), real_to_int() and int(), as well as for the
198          plus, minus and negate language operators.
199        - Added massive amount of NKSP test cases for standard measuring units and
200          'final' operator usage cases.
201        - Added NKSP test cases for (floating point tolerance aware) real number
202          equalness / unequalness comparison.
203        - Added NKSP int array and real array tests for value assignment and
204          initialization of arrays.
205        - Added NKSP test cases for built-in functions "round()", "ceil()",

221        - Fixed behavior of built-in NKSP functions change_sustain(),
222          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
223          and change_cutoff_release().
224    
225      * general changes:
226        - Only play release trigger samples on sustain pedal up if this behaviour
227          was explicitly requested by the instrument (otherwise only on note-off).

239    
240      * SFZ format engine:
241        - Fixed memory leak when releasing samples

246          (fixes bug #310, patch by Jacek Roszkowski).
247    
248    Version 2.1.0 (25 Nov 2017)
249

262        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
263          all if an up-pitch of more than 40 semi tones was requested (I don't
264          think there is any stock gig sound that requires this behavior to
265          resemble its original sound).
266        - Added support for controlling whether the individual EGADSR stages may
267          be aborted (as LinuxSampler extension to the original GigaStudio 4
268          format).
269    
270    * general changes:    * general changes:

289        - Fix: Release trigger voices can now also distinguish correctly between
290          note-off and sustain pedal up events.
291        - All engines: Increased ramp speed of volume smoother and pan smoother
292          (while slow rate of crossfade smoother is preserved) to allow quick
293          volume and pan changes by instrument scripts for instance.
294        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
295          properly and thus were ignored for certain uses.
296        - Added new C++ API method
297          VirtualMidiDevice::SendChannelPressureToSampler().

305          have a valid sample mapped (fixes bug #252).
306        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
307        - linuxsampler binary fix: option --create-instruments-db ignored
308          subsequent optional argument due to glibc's implementation oddity
309          which expects a "=" sign, but no space between them.

378        - Implemented built-in script function "stop_wait()".
379        - Implemented built-in script variable "$NI_CALLBACK_ID".
380        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
381        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
382        - Added support for read-only built-in variables (respectively
383          handled by the script parser).

385        - Added built-in script constant "$NI_CB_TYPE_NOTE".
386        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

392        - Fixed all change_*() built-in script functions to apply their
393          synthesis parameter changes immediately in case the respective note
394          was triggered at the same time, instead of scheduling the parameter
395          change, especially because it would cause some parameter types's
396          changes either to be ramped (i.e. change_vol()) or other types even
397          to have not effect at all (i.e. change_attack()).
398        - Implemented built-in script function "sh_left()".

402        - NKSP Fix: "init" event handler was not always executed when a script
403          was loaded.
404        - NKSP built-in wait() script function: abort script execution if
405          a negative or zero wait time was passed as argument (since this is
406          a common indication of a bug either of the script or even of the
407          engine, which could lead to RT instability or even worse).
408        - ScriptVM: Implemented automatic suspension of RT safety
409          threatening scripts.
410        - Provide more user friendly error messages on syntax errors.
411        - Fixed NKSP parser warning "Not a statement" when assigning an

420        - Implemented built-in script function "change_tune_time()".
421        - Implemented built-in script function "fade_in()".
422        - Implemented built-in script function "fade_out()".
423        - Fixed acceptance of wrong data type of parameters passed to built-in
424          script functions "change_vol()", "change_tune()", "change_pan()",
425          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
426          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
427          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
428        - Added built-in script function "get_event_par()" and implemented some
429          of its possible parameter selections.
430        - Added built-in script function "set_event_par()" and implemented some
431          of its possible parameter selections.
432        - Fixed a bunch of scheduler time related bugs.
433        - Fixed polyphonic variables not being reset to zero after usage.
434        - Built-in "ignore_event()" function: argument is now optional, like with
435          built-in function "ignore_controller()".
436        - Implemented built-in script function "change_velo()".
437        - Implemented built-in script function "change_note()".
438        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
439          intuitive behavior if used in combination with "change_vol_time()" or
440          "change_tune_time()" respectively: now tuning/volume changes are only
441          assigned (without delay) immediately to a new note if the respective
442          timing function has not been called before, otherwise the volume/tuning
443          changes are automatically faded (before, only the event's time stamp was
444          relevant).
445         - Implemented built-in script function "array_equal()".
446         - Implemented built-in script function "search()".
447         - Implemented built-in script function "sort()".
448         - NKSP Fix: Never suspend "init" event handlers.
449         - Implemented built-in script function "same_region()" (currently only
450           available for gig format engine).
451         - Added built-in script constant "$NKSP_LINEAR".
452         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
453         - Implemented built-in script function "change_vol_curve()".
454         - Implemented built-in script function "change_tune_curve()".
455         - built-in "play_note()" function now supports a sample playback start
456           offset with argument 3, where special value -1 means to use the regular
457           sample offset as defined by the instrument file.
458         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
459         - Built-in variable $EVENT_NOTE is now a read-only variable.
460         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
461         - built-in "play_note()" function now accepts -2 for its fourth argument
462           (note duration) which means the life time of the note shall be sticked
463           to the requested note number of argument 1.
464         - Fix: built-in "play_note()" function now returns 0 as result value if
465           -1 was passed for its fourth argument (note duration) and the respective
466           parent note is already gone.
467        - Implemented built-in script function "change_play_pos()".
468        - NKSP language: Added support for user declared const array variables.

476        - Fixed potential memory access bug and potential undefined behavior of
477          "init" event handlers.
478        - Print a time stamp along to each call of built-in function "message()".
479        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
480          to retrieve all code blocks filtered out by the preprocessor.
481        - Added built-in script function "fork()".
482        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
483        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
484        - Fixed potential crash when accessing dynamic built-in array variables.

487        - Added built-in constant $CALLBACK_STATUS_QUEUE.
488        - Added built-in constant $CALLBACK_STATUS_RUNNING.
489        - Removed max. value limitation of built-in functions "change_attack()",
490          "change_decay()" and "change_release()" to i.e. allow passing 2000000
491          for doubling the respective time.
492        - NKSP script editor syntax highlighting API: Fixed app termination due
493          to a lexer start condition stack underrun.
494        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
495          USE_CODE_IF_NOT() preprocessor statements.
496        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
497          can be set to disable all subsequent built-in "message()" function calls
498          on preprocessor level.
499        - Implemented built-in script function "change_sustain()".
500        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
501          to avoid the editor app to crash on ill-formed text input.
502        - Added built-in script function "change_pan_time()".
503        - Added built-in script function "change_pan_curve()".
