3      * Real-time instrument scripts:
4        - Fix: Do not share compiled instrument scripts among multiple engine
5          channels (sampler parts) as this can lead to crashes and would allow the
6          same global script variables to be accessible from multiple engine
7          channels which would not be the expected behaviour by instrument script
8          authors.
9    
10      * GigaStudio/Gigasampler format engine:
11        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
12          issues with .gig file.
13        - Use libgig's new method gig::File::GetSample() with method
14          gig::File::CountSamples() instead of now deprecated
15          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
16        - Use libgig's new method gig::Instrument::GetRegionAt() with method
17          gig::Instrument:CountRegions() instead of now deprecated
18          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
19        - Use libgig's gig::File::GetInstrument() method with method
20          gig::File::CountInstruments() instead of now deprecated
21          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.

50      - Renamed type LFOUnsigned -> LFOTriangleUnsigned.      - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
51      - Using now cubic interpolation as resampling algorithm by default; and      - Using now cubic interpolation as resampling algorithm by default; and
52        linear interpolation is deprecated now.        linear interpolation is deprecated now.
53        - Event:Init(): memset() entire Event::Param union to zero instead of trying
54          to do that for its individual members; the latter became error prone due
55          to the union's growing complexity meanwhile.
56        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
57          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
58          methods and marked the old ones as deprecated; and likewise added new
59          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
60          methods and marked those old ones deprecated as well.
61        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
62          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
63        - Implemented support for compressed RPN/NRPN message sequences (that is to
64          allow processing MIDI data entry messages without always having to be
65          preceded strictly by RPN/NRPN parameter selection messages on each value
66          change).
67        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
68          decrement).
69        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
70          MSB=127 and LSB=127) and which is disabling subsequent data
71          entry/increment/decrement CC messages.
72        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
73          instrument editor.
74        - Fixed playing noise at the end of a disk stream under certain conditions.
75        - Fixed potential crash with high pitch at end of RAM playback.
76        - Added configure checks whether C++ compiler supports so called
77          'designated initializers'.
78        - Added global backtraceAsString() function for debugging purposes
79          (POSIX systems only, no Windows implementation yet).
80        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
81          nameOfCaller() and setNameOfCaller().
82        - configure: Always check for availability of pthread_testcancel() and use
83          it if so (previously it was only used if explicitly enabled by configure
84          option).
85        - Thread class: raise compiler warning if pthread_testcancel() is not
86          available, because it can lead to deadlocks.
87        - Mutex class: Implemented optional bug detection and deadlock debugging
88          features.
89        - Ref<> class is now thread safe (as lock-free and wait-free
90          implementation).
91        - Fixed compilation error with Bison >= 3.6.0.
92        - Fixed rare crash when switching between instruments that had instrument
93          scripts loaded.
94        - Allow EffectChain::InsertEffect() as alternative to
95          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
96        - ConstCapacityArray class: Fixed bug in remove() method.
97        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
98          real-time instrument script was loaded.

# Line 200  Version SVN trunk (?) Line 268  Version SVN trunk (?)
268      - Added built-in script real number constant "~NI_MATH_PI".      - Added built-in script real number constant "~NI_MATH_PI".
269      - Added built-in script real number constant "~NI_MATH_E".      - Added built-in script real number constant "~NI_MATH_E".
270      - NKSP language: Allow unary '+' operator.      - NKSP language: Allow unary '+' operator.
271        - Added built-in script functions "msb()" and "lsb()".
272        - NKSP language: Added support for RPN event handler
273          ("on rpn ... end on" in instrument scripts).
274        - NKSP language: Added support for NRPN event handler
275          ("on nrpn ... end on" in instrument scripts).
276        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
277          may be read from the new RPN/NRPN script handlers to get the (N)RPN
278          parameter that had been changed and its new value.
279        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
280          which are identifying the new (N)RPN handlers as such at script runtime.
281        - Implemented built-in script function "set_rpn()".
282        - Implemented built-in script function "set_nrpn()".
283        - Fix: built-in functions returning an array type were broken and caused a
284          crash when the built-in function's (supposed to be array) result value was
285          used by the script VM.
286        - Removed upper value constraint for 2nd argument of built-in functions
287          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
288          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
289          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
290          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
291          the LFO frequency / resonance / cutoff frequency.
292        - Reduced code involved for parsing NKSP variable declarations by using 2
293          generalized grammar rules with optional components (i.e. optional value
294          assignment and optional variable qualifiers) instead of previous linear
295          combinations of grammar rules, which also fixes some edge case.
296        - NKSP language parser: track code block locations also by a) raw byte
297          position in NKSP source code string and b) length of that code block in
298          bytes (along to the already existing code block tracking by line/column);
299          and added appropriate new members to public C++ API classes like
300          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
301        - NKSP language: Added support for 'patch' variable qualifier (capture their
302          locations and allow replacement of their assignment expression via VM C++
303          API).
304        - Fixed incorrect EG times if standard measuring unit was passed to built-in
305          functions "change_attack()", "change_decay()" or "change_release()".
306        - Fixed intermediate function result values never having reflected any
307          standard measuring unit type.
308        - Fixed re-entrant issue with function calls which caused wrong result
309          values if the same function was called multiple times in a term
310          (specifically if metric prefixes were used).
311        - NKSP language: Just throw a warning, not an error if an array variable of
312          size zero was declared.
313        - NKSP language: Allow omitting explicit array size on array variable
314          declaration if combined with immediate value assignment
315          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
316        - NKSP language: emit warning if an array variable was declared with bigger
317          array size than amount of initial values been assigned, and initialize the
318          missing array elements with zero in this case.
319        - Fixed built-in NKSP exit() function to behave as return statement.
320        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
321          data type.
322        - NKSP VM: Fixed the "release" handler being executed too often under
323          certain situations if polyphonic data was passed from "note" handler to
324          "release" handler.
325        - Fixed memory leak in NKSP parser: string tokens were allocated as C
326          strings and never freed.
327        - Fixed incorrect polyphonic data transfer from wrong note handler to
328          release handler; which also fixes no release handler being executed
329          sometimes, and due to the latter it also fixes potential crashes as some
330          polyphonic script events were never released and the engine hence was
331          running out of free script events.
332        - Fixed crash when handling array results of built-in functions
333          (e.g. "num_elements(by_marks($MARK_1)").
334        - NKSP VM: Fixed dead note events not been removed from user's event groups
335          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
336          and set_event_mark() after max. size of event group list was exhausted).
337    
338    * test cases:    * test cases:
339      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

358        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
359        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
360      - Added NKSP test cases for unary '+' operator.      - Added NKSP test cases for unary '+' operator.
361        - Added NKSP test cases for core built-in variables.
362        - Added thorough NKSP test cases for variable declarations.

378      - Format extension: Support for additional filter types:      - Format extension: Support for additional filter types:
379        lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,        lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
380        bandreject 2-pole.        bandreject 2-pole.
381        - Fixd potential crash with polynomial interpolator and max. pitch.
382        - If minimum cutoff is defined, remap cutoff controller CC values to really
383          span the entire possible cutoff range (and avoiding a dead controller
384          zone).
385        - Implemented support for loading instrument scripts with 'patch' variables
386          (by patching these script variables with potentially overridden ones by
387          gig Instrument).
