# Line 1  Line 1 
1  Version CVS HEAD (?)  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        - 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        - Fixed potential crash with high pitch at end of RAM playback.
54        - Added configure checks whether C++ compiler supports so called
55          'designated initializers'.
56        - Added global backtraceAsString() function for debugging purposes
57          (POSIX systems only, no Windows implementation yet).
58        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59          nameOfCaller() and setNameOfCaller().
60        - configure: Always check for availability of pthread_testcancel() and use
61          it if so (previously it was only used if explicitly enabled by configure
62          option).
63        - Thread class: raise compiler warning if pthread_testcancel() is not
64          available, because it can lead to deadlocks.
65        - Mutex class: Implemented optional bug detection and deadlock debugging
66          features.
67        - Ref<> class is now thread safe (as lock-free and wait-free
68          implementation).
69        - Fixed compilation error with Bison >= 3.6.0.
70    
71      * Real-time instrument scripts:
72        - Added method ScriptVM::setExitResultEnabled() which allows to
73          explicitly enable the built-in exit() function to optionally accept
74          one function argument; the value of the passed exit() function
75          argument will then become available by calling
76          VMExecContext::exitResult() after script execution.
77        - 64 bit support for NKSP integer scripts variables (declare $foo).
78        - Variable names, function names and preprocessor condition names must start
79          with a regular character (a-z or A-Z); starting them with a digit or
80          underscore is not allowed.
81        - NKSP parser fix: equal comparison operator "=" and not equal comparison
82          operator "#" must only accept integer operands.
83        - NKSP language: Implemented support for standard units like Hertz, seconds,
84          Bel including support for metric unit prefixes; so one can now e.g.
85          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
86          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
87          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
88        - NKSP language: Introduced "final" operator "!" which is specifically
89          intended for synthesis parameter values to denote that the synthesis
90          parameter value is intended to be the "final" value for that synthesis
91          parameter that should explicitly be used by the engine and thus causing
92          the sampler engine to ignore all other modulation sources for the same
93          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
94          variable or formula with this new "!" operator the expression is marked as
95          being "final".
96        - NKSP script editor API: Added support for detecting standard unit tokens
97          and their potential metric prefix token.
98        - NKSP language: Added support for NKSP real number literals and
99          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
100        - NKSP language: Added support for NKSP real number (floating point) script
101          variables (declare ~foo).
102        - NKSP language: Added support for NKSP real number (floating point) array
103          script variables (declare ?foo[]).
104        - Built-in script function "message()" accepts now real number argument as
105          well.
106        - Added built-in script function "real_to_int()" and its short hand form
107          "int()" for casting from real number to integer in NKSP scripts.
108        - Added built-in script function "int_to_real()" and its short hand form
109          "real()" for casting from integer to real number in NKSP scripts.
110        - Allow built-in exit() function to potentially accept real number type
111          argument as well.
112        - Built-in script functions may have a different return type depending on
113          the arguments passed to the function.
114        - Built-in script function "abs()" optionally accepts and returns real
115          number.
116        - Built-in script functions "min()" and "max()" optionally accept real
117          number arguments and return real number as result in that case.
118        - NKSP VM API: Allow units and 'final'ness to be returned as result from
119          built-in functions (added methods VMFunction::returnUnitType() and
120          VMFunction::returnsFinal() for that purpose which must be implemented by
121          built-in function implementations).
122        - NKSP language: Allow metric unit prefixes of numeric scalar and array
123          variables to be changed freely at runtime (unlike unit types like Hz etc.
124          which are still sticky, parse-time features of variables which cannot be
125          changed at runtime for the intentional sake of determinism).
126        - NKSP language: 'final' values are prohibited for array variables for now
127          (attempt causes a parsers error).
128        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
129          conditions of runtime control structures like if(), while(), select()
130          (attempt causes a parser error).
131        - NKSP VM API: Allow built-in functions to perform their own, individual
132          parse time checks of arguments going to be passed to the function at
133          runtime (added method VMFunction::checkArgs() for that purpose).
134        - NKSP language: raise parser warning if only one operand of binary
135          operators (like logical 'or' comparison) contain a 'final' value (because
136          it would always yield in a 'final' result in such cases).
137        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
138          different metric unit prefixes, which will behave as expected (e.g.
139          result of expression '1000us < 2ms' is true).
140        - NKSP language: Allow adding values with different metric unit prefixes
141          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
142        - NKSP language: Allow subtracting values with different metric unit
143          prefixes (e.g. result of expression '1ms - 20us' is '980us').
144        - NKSP language: Allow multiplying with any metric unit prefixes
145          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
146          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
147          we don't have any considerable practical use for a term like '4s^2'
148          (hence any attempt multiplying two unit types still causes parser error).
149        - NKSP language: Allow dividing by any metric unit prefixes and allow
150          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
151          yields in unit free result '8'). So this is now a way to cast units away
152          e.g. for passing the result to other expressions, certain function calls
153          or variables which are not accepting any units (or that specific unit).
154        - NKSP language: integer arrays and real number arrays can now be converted
155          to strings (e.g. for dumping their content with message() calls for
156          script debugging purposes).
157        - NKSP language: expressions and variables with units are now correctly
158          casted to strings (e.g. with message() calls).
159        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
160          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
161          floating point tolerances into account.
162        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
163          VMScalarNumberExpr::evalCastReal().
164        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
165          'VMIntArrayExpr' and 'VMRealArrayExpr'.
166        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
167          unitFactor() (runtime) methods.
168        - Built-in function "exit()" supports now returning units and 'final'ness
169          for test cases.
170        - The following built-in functions support now units as well: "abs()",
171          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
172          "real_to_int()", "int()", "int_to_real()" and "real()".
173        - Built-in functions "array_equal()", "search()" and "sort()" support now
174          real number arrays (correctly) as well.
175        - Added individual parse time checks of arguments to be passed to built-in
176          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
177          "array_equal()" and "search()" specific for their individual purposes.
178        - NKSP VM refactoring: Renamed all methods, functions and classes matching
179          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
180          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
181          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
182          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
183          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
184          isScalarNumber() -> isNumber()).
185        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
186          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
187          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
188          as convenient methods for automatically converting values to expected
189          metric value basis.
190        - Built-in function "wait()" accepts now both integers and real numbers as
191          argument.
192        - NKSP VM API cleanup: Get rid of legacy method
193          VMFunction::argType(vmint iArg) which was already superseded by its new
194          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
195        - NKSP parser: if wrong argument type was passed to a built-in function and
196          that built-in function accepts more than one data type for the argument,
197          then show all supported data types as parser error message.
198        - Built-in function "play_note()" accepts now real numbers and seconds as
199          unit type as well for its 3rd and 4th function arguments.
200        - The following built-in functions accept now real numbers as well for their
201          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
202          "change_attack()", "change_decay()", "change_release()",
203          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
204          "change_cutoff_sustain()", "change_cutoff_release()",
205          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
206          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
207          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
208        - Fixed built-in function "change_play_pos()" not having accepted metric
209          prefixes at all.
210        - Fixed the following built-in functions having misinterpreted values given
211          with unit type (for their 2nd argument) as if they were relative values
212          (that is as if they were passed without a unit type): "change_attack()",
213          "change_decay()", "change_release()", "change_cutoff_attack()",
214          "change_cutoff_decay()", "change_cutoff_release()".
215        - Fixed the following built-in functions having applied completely wrong
216          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
217          respective EGs being their modulation sink assume uint data type with
218          value range 0..1000 instead of 0.0..1.0.
219        - Added individual parse-time checks of function arguments for the following
220          built-in functions: "play_note()", "note_off()", "set_event_mark()",
221          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
222          "change_decay()", "change_release()", "change_cutoff_attack()",
223          "change_cutoff_decay()", "change_cutoff_release()",
224          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
225          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
226          "change_pan_time()".
227        - Don't abort function call if unit type was used and at the same time
228          'final' operator was omitted for the primary value argument of the
229          following built-in functions: "change_cutoff()", "change_attack()",
230          "change_decay()", "change_release()", "change_cutoff_attack()",
231          "change_cutoff_decay()", "change_cutoff_release()",
232          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
233          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
234          "change_pan_time()", instead imply 'final'ness at runtime and raise an
235          appropriate parser warning at parse time.
236        - Added built-in real number functions "round()", "ceil()", "floor()",
237          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
238          "cos()", "tan()", "asin()", "acos()", "atan()".
239        - Added built-in script real number constant "~NI_MATH_PI".
240        - Added built-in script real number constant "~NI_MATH_E".
241        - NKSP language: Allow unary '+' operator.
242        - Added built-in script functions "msb()" and "lsb()".
243        - NKSP language: Added support for RPN event handler
244          ("on rpn ... end on" in instrument scripts).
245        - NKSP language: Added support for NRPN event handler
246          ("on nrpn ... end on" in instrument scripts).
247        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
248          may be read from the new RPN/NRPN script handlers to get the (N)RPN
249          parameter that had been changed and its new value.
250        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
251          which are identifying the new (N)RPN handlers as such at script runtime.
252        - Implemented built-in script function "set_rpn()".
253        - Implemented built-in script function "set_nrpn()".
254        - Fix: built-in functions returning an array type were broken and caused a
255          crash when the built-in function's (supposed to be array) result value was
256          used by the script VM.
257        - Removed upper value constraint for 2nd argument of built-in functions
258          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
259          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
260          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
261          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
262          the LFO frequency / resonance / cutoff frequency.
263        - Reduced code involved for parsing NKSP variable declarations by using 2
264          generalized grammar rules with optional components (i.e. optional value
265          assignment and optional variable qualifiers) instead of previous linear
266          combinations of grammar rules, which also fixes some edge case.
267        - NKSP language parser: track code block locations also by a) raw byte
268          position in NKSP source code string and b) length of that code block in
269          bytes (along to the already existing code block tracking by line/column);
270          and added appropriate new members to public C++ API classes like
271          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
272        - NKSP language: Added support for 'patch' variable qualifier (capture their
273          locations and allow replacement of their assignment expression via VM C++
274          API).
275        - Fixed incorrect EG times if standard measuring unit was passed to built-in
276          functions "change_attack()", "change_decay()" or "change_release()".
277        - Fixed intermediate function result values never having reflected any
278          standard measuring unit type.
279        - Fixed re-entrant issue with function calls which caused wrong result
280          values if the same function was called multiple times in a term
281          (specifically if metric prefixes were used).
282        - NKSP language: Just throw a warning, not an error if an array variable of
283          size zero was declared.
284        - NKSP language: Allow omitting explicit array size on array variable
285          declaration if combined with immediate value assignment
286          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
287        - NKSP language: emit warning if an array variable was declared with bigger
288          array size than amount of initial values been assigned, and initialize the
289          missing array elements with zero in this case.
290    
291      * test cases:
292        - Fixed compiler errors in test cases.
293        - Updated README for how to compile & run test cases.
294        - Updated test case
295          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
296          expected behaviour of the Mutex class implementation (recursive
297          mutex type).
298        - Added test cases for NKSP core language aspects and core built-in
299          functions.
300        - Fixed thread tests segfaulting on Linux.
301        - NKSP: Added real number test cases for built-in functions exit(),
302          int_to_real(), real(), real_to_int() and int(), as well as for the
303          plus, minus and negate language operators.
304        - Added massive amount of NKSP test cases for standard measuring units and
305          'final' operator usage cases.
306        - Added NKSP test cases for (floating point tolerance aware) real number
307          equalness / unequalness comparison.
308        - Added NKSP int array and real array tests for value assignment and
309          initialization of arrays.
310        - Added NKSP test cases for built-in functions "round()", "ceil()",
311          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
312          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
313        - Added NKSP test cases for unary '+' operator.
314        - Added NKSP test cases for core built-in variables.
315        - Added thorough NKSP test cases for variable declarations.
316    
317      * GigaStudio/Gigasampler format engine:
318        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
319          behaviour for start_level_mid.
320        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
321          level (see discussion "GigaStudio LFO compatibility" on mailing list
322          from 2019-09-26 for details).
323        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
324          see discussion "GigaStudio LFO compatibility" on mailing list from
325          2019-09-26 for details).
326        - Format extension: Added support for different LFO wave forms (currently
327          either sine [default], triangle, saw or square).
328        - Format extension: Added support for LFO phase displacement (0°..360°).
329        - Format extension: Added support for flipping LFO polarity on LFO 3
330          (in the original gig format this was only available for LFO 1 and LFO 2).
331        - Format extension: Support for additional filter types:
332          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
333          bandreject 2-pole.
334        - Fixd potential crash with polynomial interpolator and max. pitch.
335        - If minimum cutoff is defined, remap cutoff controller CC values to really
336          span the entire possible cutoff range (and avoiding a dead controller
337          zone).
338        - Implemented support for loading instrument scripts with 'patch' variables
339          (by patching these script variables with potentially overridden ones by
340          gig Instrument).
341    
342      * SFZ format engine:
343        - Fixed support for regions with loccN/hiccN conditions on more than one
344          MIDI controller.
345    
346      * Benchmarks:
347        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
348          algorithm (since result of 2nd run was not accumulated).
349        - Added benchmark for saw wave (benchmarks/saw.cpp).
350        - Added benchmark for sine wave (benchmarks/sine.cpp).
351        - Added benchmark for square wave (benchmarks/square.cpp).
352        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
353          which are large enough on modern systems.
354    
355    Version 2.1.1 (27 Jul 2019)
356    
357      * Real-time instrument scripts:
358        - Fixed behavior of built-in NKSP functions change_sustain(),
359          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
360          and change_cutoff_release().
361    
362      * general changes:
363        - Only play release trigger samples on sustain pedal up if this behaviour
364          was explicitly requested by the instrument (otherwise only on note-off).
365        - Fixed compiler warnings.
366        - Fixed compilation error when cross-compiling to Mac.
367        - FX Sends: Provide more useful error messages on routing problems
368          (see bug #169).
369        - LSCP doc: Be more clear describing the two distinct approaches
370          of using external vs. internal effects (see bug #169).
371        - "optional" class: Fixed comparison operators.
372    
373      * Gigasampler/GigaStudio format engine:
374        - Format extension: If requested by instrument then don't play release
375          trigger sample on note-off events.
376    
377      * SFZ format engine:
378        - Fixed memory leak when releasing samples
379          (fixes bug #307, patch by Jacek Roszkowski)
380        - Fixed potential crash when a sample is shared by more than one region
381          (fixes bug #308, patch by Jacek Roszkowski).
382        - Opcode 'sample': Added support for built-in sample '*silence'
383          (fixes bug #310, patch by Jacek Roszkowski).
384    
385    Version 2.1.0 (25 Nov 2017)
386    
387      * SFZ format engine:
388        - added support for <global>, <master> and #define (patch by Alby M)
389        - Removed code duplication in SFZ file loading code.
390        - Added support for sfz extension opcode 'script' which may be used to
391          load real-time instrument script file (NKSP script language).
392        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
393        - Fixed unintended volume fade-in of voices under certain conditions.
394        - sfz parser: allow missing space between header and opcode
395    
396      * Gigasampler/GigaStudio format engine:
397        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
398          cutoff settings.
399        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
400          all if an up-pitch of more than 40 semi tones was requested (I don't
401          think there is any stock gig sound that requires this behavior to
402          resemble its original sound).
403        - Added support for controlling whether the individual EGADSR stages may
404          be aborted (as LinuxSampler extension to the original GigaStudio 4
405          format).
406    
407      * general changes:
408        - fixed printf type errors (mostly in debug messages)
409        - use unique_ptr instead of auto_ptr when building with C++11
410        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
411          allowing to sort data efficiently in real-time safe manner.
412        - RTList class: added methods for moving/inserting elements to arbitrary
413          position within a list.
414        - RTList class: added method fromPtr() for creating an Iterator object from
415          a raw element pointer.
416        - Attempt to partly fix resetting engine channels vs. resetting engine, an
417          overall cleanup of the Reset*(), ConnectAudioDevice(),
418          DisconnectAudioDevice() API methods would still be desirable though,
419          because the current situation is still inconsistent and error prone.
420        - Active voices are now internally grouped to "Note" objects, instead of
421          being directly assigned to a keyboard key. This allows more fine graded
422          processing of voices, which is i.e. required for certain instrument
423          script features.
424        - Fix: Release trigger voices were not spawned on sustain pedal up
425          (CC #64) events.
426        - Fix: Release trigger voices can now also distinguish correctly between
427          note-off and sustain pedal up events.
428        - All engines: Increased ramp speed of volume smoother and pan smoother
429          (while slow rate of crossfade smoother is preserved) to allow quick
430          volume and pan changes by instrument scripts for instance.
431        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
432          properly and thus were ignored for certain uses.
433        - Added new C++ API method
434          VirtualMidiDevice::SendChannelPressureToSampler().
435        - windows, 32-bit: fixed potential crashes by making sure the stack in
436          sub threads is 16-byte aligned
437        - fixed numerous compiler warnings
438        - Fixed invalid (note-on) event ID being assigned to new Note objects.
439        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
440          fixes potential undefined behavior.
441        - Fixed Note object leak when triggering notes on keys which did not
442          have a valid sample mapped (fixes bug #252).
443        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
444        - linuxsampler binary fix: option --create-instruments-db ignored
445          subsequent optional argument due to glibc's implementation oddity
446          which expects a "=" sign, but no space between them.
447    
448      * packaging changes:
449        - removed unnecessary dependency to libuuid
450          (originated by libgig's usage of it)
451        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
452          auto detect whether it (sh/c)ould output its messages in color.
453        - Debian: Fixed packaging error about invalid "Source-Version"
454          substitution variable.
455        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
456        - Debian: Added build dependency to libsqlite3-dev for building
457          linuxsampler with instruments DB support.
458    
459      * Real-time instrument scripts:
460        - Implemented scheduler for delayed MIDI events and for suspended scripts.
461        - Built-in script function "wait()": implemented support for function's
462          "duration-us" argument, thus scripts using this function are now
463          correctly resumed after the requested amount of microseconds.
464        - Built-in script function "play_note()": implemented support for
465          function's "duration-us" argument, thus notes triggered with this
466          argument are now correctly released after the requested amount of
467          microseconds.
468        - Fix: script events were not cleared when engine channel was reset,
469          potentially causing undefined behavior.
470        - Fixed crash which happened when trying to reference an undeclared
471          variable.
472        - Built-in script function "play_note()": Added support for passing
473          special value -1 for "duration-us" argument, which will cause the
474          triggered note to be released once the original note was released.
475        - Instrument script classes now exported with the liblinuxsampler C++ API.
476        - Added new API method ScriptVM::syntaxHighlighting() which provides
477          a convenient syntax highlighting backend for external instrument
478          script editor applications.
479        - Added new C++ API class "ScriptVMFactory".
480        - Extended parser issues to provide not only first line and first
481          column, but also last line and last column of issue (thus marking
482          the precise span of the issue within the source code).
483        - Reload script automatically after being modified by an instrument
484          editor.
485        - NKSP language grammar correction: allow empty event handler bodies
486          like "on note end on".
487        - Implemented built-in script function "change_vol()".
488        - Implemented built-in script function "change_tune()".
489        - Implemented built-in script function "change_pan()".
490        - Implemented built-in script function "change_cutoff()".
491        - Implemented built-in script function "change_reso()".
492        - Implemented built-in script function "event_status()".
493        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
494          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
495          "event_status()" function.
496        - NKSP language: Added support for bitwise operators ".or.", ".and."
497          and ".not.".
498        - NKSP language scanner: Fixed IDs matching to require at least one
499          character (i.e. when matching function names or variable names).
500        - NKSP language scanner: disabled unusued rules.
501        - Fixed behavior of play_note() and note_off() functions which must
502          be distinguished engine internally from "real" MIDI note on/off
503          events in order to avoid misbehaviors like hanging notes.
504        - Implemented built-in script variable "$KSP_TIMER".
505        - Implemented built-in script variable "$NKSP_REAL_TIMER".
506        - Implemented built-in script variable "$NKSP_PERF_TIMER".
507        - Implemented built-in script variable "$ENGINE_UPTIME".
508        - Implemented built-in script function "inc()".
509        - Implemented built-in script function "dec()".
510        - NKSP language fix: division expressions were evaluated too often.
511        - NKSP language fix: string concatenation operator was right
512          associative instead of left (to right).
513        - NKSP language correction: allow empty statements in entire language
514          (i.e. "if end if").
515        - Implemented built-in script function "stop_wait()".
516        - Implemented built-in script variable "$NI_CALLBACK_ID".
517        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
518        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
519        - Added support for read-only built-in variables (respectively
520          handled by the script parser).
521        - Added built-in script constant "$NI_CB_TYPE_INIT".
522        - Added built-in script constant "$NI_CB_TYPE_NOTE".
523        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

527        - Implemented built-in script function "change_decay()".
528        - Implemented built-in script function "change_release()".
529        - Fixed all change_*() built-in script functions to apply their
530          synthesis parameter changes immediately in case the respective note
531          was triggered at the same time, instead of scheduling the parameter
532          change, especially because it would cause some parameter types's
533          changes either to be ramped (i.e. change_vol()) or other types even
534          to have not effect at all (i.e. change_attack()).
535        - Implemented built-in script function "sh_left()".
536        - Implemented built-in script function "sh_right()".
537        - Implemented built-in script function "min()".
538        - Implemented built-in script function "max()".
539        - NKSP Fix: "init" event handler was not always executed when a script
540          was loaded.
541        - NKSP built-in wait() script function: abort script execution if
542          a negative or zero wait time was passed as argument (since this is
543          a common indication of a bug either of the script or even of the
544          engine, which could lead to RT instability or even worse).
545        - ScriptVM: Implemented automatic suspension of RT safety
546          threatening scripts.
547        - Provide more user friendly error messages on syntax errors.
548        - Fixed NKSP parser warning "Not a statement" when assigning an
549          initializer list to an array variable.
550        - Implemented built-in script array variable "%ALL_EVENTS".
551        - Implemented built-in script function "in_range()".
552        - Implemented built-in script function "change_amp_lfo_depth()".
553        - Implemented built-in script function "change_amp_lfo_freq()".
554        - Implemented built-in script function "change_pitch_lfo_depth()".
555        - Implemented built-in script function "change_pitch_lfo_freq()".
556        - Implemented built-in script function "change_vol_time()".
557        - Implemented built-in script function "change_tune_time()".
558        - Implemented built-in script function "fade_in()".
559        - Implemented built-in script function "fade_out()".
560        - Fixed acceptance of wrong data type of parameters passed to built-in
561          script functions "change_vol()", "change_tune()", "change_pan()",
562          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
563          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
564          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
565        - Added built-in script function "get_event_par()" and implemented some
566          of its possible parameter selections.
567        - Added built-in script function "set_event_par()" and implemented some
568          of its possible parameter selections.
569        - Fixed a bunch of scheduler time related bugs.
570        - Fixed polyphonic variables not being reset to zero after usage.
571        - Built-in "ignore_event()" function: argument is now optional, like with
572          built-in function "ignore_controller()".
573        - Implemented built-in script function "change_velo()".
574        - Implemented built-in script function "change_note()".
575        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
576          intuitive behavior if used in combination with "change_vol_time()" or
577          "change_tune_time()" respectively: now tuning/volume changes are only
578          assigned (without delay) immediately to a new note if the respective
579          timing function has not been called before, otherwise the volume/tuning
580          changes are automatically faded (before, only the event's time stamp was
581          relevant).
582         - Implemented built-in script function "array_equal()".
583         - Implemented built-in script function "search()".
584         - Implemented built-in script function "sort()".
585         - NKSP Fix: Never suspend "init" event handlers.
586         - Implemented built-in script function "same_region()" (currently only
587           available for gig format engine).
588         - Added built-in script constant "$NKSP_LINEAR".
589         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
590         - Implemented built-in script function "change_vol_curve()".
591         - Implemented built-in script function "change_tune_curve()".
592         - built-in "play_note()" function now supports a sample playback start
593           offset with argument 3, where special value -1 means to use the regular
594           sample offset as defined by the instrument file.
595         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
596         - Built-in variable $EVENT_NOTE is now a read-only variable.
597         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
598         - built-in "play_note()" function now accepts -2 for its fourth argument
599           (note duration) which means the life time of the note shall be sticked
600           to the requested note number of argument 1.
601         - Fix: built-in "play_note()" function now returns 0 as result value if
602           -1 was passed for its fourth argument (note duration) and the respective
603           parent note is already gone.
604        - Implemented built-in script function "change_play_pos()".
605        - NKSP language: Added support for user declared const array variables.

609        - NKSP language: Added support for "synchronized .. end synchronized"
610          code blocks.
611        - Implemented built-in script function "abort()" which allows to abort
612          another script handler by passing its callback ID.
613        - Fixed potential memory access bug and potential undefined behavior of
614          "init" event handlers.
615        - Print a time stamp along to each call of built-in function "message()".
616        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
617          to retrieve all code blocks filtered out by the preprocessor.
618        - Added built-in script function "fork()".
619        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
620        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
621        - Fixed potential crash when accessing dynamic built-in array variables.
622        - Added built-in script function "callback_status()".

624        - Added built-in constant $CALLBACK_STATUS_QUEUE.
625        - Added built-in constant $CALLBACK_STATUS_RUNNING.
626        - Removed max. value limitation of built-in functions "change_attack()",
627          "change_decay()" and "change_release()" to i.e. allow passing 2000000
628          for doubling the respective time.
629        - NKSP script editor syntax highlighting API: Fixed app termination due
630          to a lexer start condition stack underrun.
631        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
632          USE_CODE_IF_NOT() preprocessor statements.
633        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
634          can be set to disable all subsequent built-in "message()" function calls
635          on preprocessor level.
636        - Implemented built-in script function "change_sustain()".
637        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
638          to avoid the editor app to crash on ill-formed text input.
639        - Added built-in script function "change_pan_time()".
640        - Added built-in script function "change_pan_curve()".

649        - Fixed memory access bug of general DB access code which lead to
650          undefined behavior.
651        - Cleanup of instruments DB file creation and opening code.
652        - The instrument DB path of linuxsampler's --create-instruments-db argument
653          is now optional, if it is missing, then a default location is used.
654        - Added support for scanning SFZ (.sfz) files.
655        - Added support for scanning Sound Font (.sf2) files.
656        - Fixed undefined DB transaction behavior.

717        - implemented support for internal LADSPA effects
718        - raised limit of program change queue from 100 to 512
719          (as suggested by Alex Stone)
720        - implemented sine LFO, pulse LFO and saw LFO
721        - experimental support for per voice equalization
722        - added command line option --exec-after-init
723        - Introduced new C++ API method:
724          EngineChannel::InstrumentFileName(int index)
725          allowing to retrieve the whole list of files used for the loaded
726          instrument on an engine channel (a.k.a. part). Some GigaStudio
727          instruments for example are splitted over several files like
728          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
729        - Added new C++ API method Sampler::GetGlobalMaxVoices().
730        - Added new C++ API method Sampler::GetGlobalMaxStreams().
731        - Added new C++ API method Sampler::SetGlobalMaxVoices().
732        - Added new C++ API method Sampler::SetGlobalMaxStreams().
733        - Various "const" and "restrict" optimizations.
734        - all engines: add pan CC value to instrument pan parameter before
735          applying panning, instead of using two separate pan functions in
736          series (#182)
737        - added a lock guard class for exception safe mutex handling and
738          used it everywhere appropriate
739        - Immediately apply scale tuning changes to active voices.
740        - Exposed scale tuning to C++ API (along to the already existing standard
741          SysEx way).
742        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
743          and broken for ppc64. (Seq_cst loads and stores are actually not
744          used in LS, so the bug wasn't noticable.)
745        - lsatomic.h: added ARMv7 support
746        - Added support for multiple MIDI input ports per sampler channel (and
747          added various new C++ methods for this new feature / design change, old
748          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
749          as deprecated but are still there and should provide full behavior
750          backward compatibility).
751        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
752          unsafe and caused compilation error with clang 2.x).
753        - Bugfix: only process the latest MIDI program change event.
754        - Introducing the LSCP shell, which provides convenient control of the
755          sampler from the command line by providing LSCP aware features.
756        - VirtualMidiDevice: Added support for program change.
757        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
758        - VirtualMidiDevice: Added support for pitch bend.
759        - Aftertouch: extended API to explicitly handle channel pressure and
760          polyphonic key pressure events (so far polyphonic pressure was not
761          supported at all, and channel pressure was rerouted as CC128 but not
762          used so far).
763        - Added initial support for real-time instrument scripts. The script VM
764          code is shared by all sampler engine implemementations, however only the
765          gig file format currently provides support for storing instrument scripts
766          (as LinuxSampler extension to the original GigaStudio 4 format).

778        - handle special case when pan parameter in gig file has max or
779          min value
780        - Exclusive Groups: don't ever stop voices of the same note,
781          doesn't sound naturally with a drumkit

1150        - fixed crash which occurred when changing an already deployed sampler
1151          channel to a different engine type
1152        - fixed crash when deleting a sampler channel or changing engine
1153          type while an instrument load was in progress
1154        - bugfix: playing a note while changing the instrument could cause
1155          a crash, or give "Handing back unknown region" error messages
1156        - bugfix: calling SET VOICES (which Fantasia does on start and
1157          refresh) could cause instruments to be unloaded
1158        - Mac OS X: fixed name collision of enum in EffectControl and
1159          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1160        - Mac OS X: fixed hanging threads
1161        - Windows: disabled the previous thread fix on non-Mac systems, as
1162          it caused hanging threads on Windows
1163        - Fixed possible crashes due to corrupted MIDI/audio device list
1164          after MIDI/audio device creation failure
1165        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1166          instruments were uselessly precached with zero samples, however it still
1167          took the full preloading time and on 1st program change the respective
1168          instrument was completely reloaded again.
1169        - fixed handling of rapid bank select and program change messages
1170          sent to the same sampler channel (patch from the Open Octave
1171          project, slightly adjusted)
1172        - fixed crash when trying to create an effect instance with controls
1173          which min and/or max values depend on the sample rate
1174        - fixed bug #162
1175        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1176          multiple paths (#165)
1177        - thread safety fixes for the instrument loading thread
1178        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1179          (#176)
1180        - more thread safety fixes for the instrument loading thread
1181        - sfz/sf2 engine: fixed crash when using small audio fragment size
1182        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1183        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1184          introduced in previous fix)
1185        - fixed crash when a channel received a program change while
1186          playing a note in a key group
1187        - fixed erroneous error message piping in VoiceBase.h
1188          (labelled "Disk stream not available in time")
1189        - Update effects on sample rate & period size changes (to avoid
1190          crashes and noise on such transitions).
1191        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1192          (fixes #208)
1193        - Fixed bug in LSCP grammar definition which caused a statement like
1194          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1195          practically irrelevant, however it caused problems with the new LSCP
1196          shell's auto completion feature).
1197        - Fixed MIDI program change messages being ignored if quickly executed
1198          after each other (fixes #231).
