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    
40      * Real-time instrument scripts:
41        - Added method ScriptVM::setExitResultEnabled() which allows to
42          explicitly enable the built-in exit() function to optionally accept
43          one function argument; the value of the passed exit() function
44          argument will then become available by calling
45          VMExecContext::exitResult() after script execution.
46        - 64 bit support for NKSP integer scripts variables (declare $foo).
47        - Variable names, function names and preprocessor condition names must start
48          with a regular character (a-z or A-Z); starting them with a digit or
49          underscore is not allowed.
50        - NKSP parser fix: equal comparison operator "=" and not equal comparison
51          operator "#" must only accept integer operands.
52        - NKSP language: Implemented support for standard units like Hertz, seconds,
53          Bel including support for metric unit prefixes; so one can now e.g.
54          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
55          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
56          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
57        - NKSP language: Introduced "final" operator "!" which is specifically
58          intended for synthesis parameter values to denote that the synthesis
59          parameter value is intended to be the "final" value for that synthesis
60          parameter that should explicitly be used by the engine and thus causing
61          the sampler engine to ignore all other modulation sources for the same
62          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
63          variable or formula with this new "!" operator the expression is marked as
64          being "final".
65        - NKSP script editor API: Added support for detecting standard unit tokens
66          and their potential metric prefix token.
67        - NKSP language: Added support for NKSP real number literals and
68          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
69        - NKSP language: Added support for NKSP real number (floating point) script
70          variables (declare ~foo).
71        - NKSP language: Added support for NKSP real number (floating point) array
72          script variables (declare ?foo[]).
73        - Built-in script function "message()" accepts now real number argument as
74          well.
75        - Added built-in script function "real_to_int()" and its short hand form
76          "int()" for casting from real number to integer in NKSP scripts.
77        - Added built-in script function "int_to_real()" and its short hand form
78          "real()" for casting from integer to real number in NKSP scripts.
79        - Allow built-in exit() function to potentially accept real number type
80          argument as well.
81        - Built-in script functions may have a different return type depending on
82          the arguments passed to the function.
83        - Built-in script function "abs()" optionally accepts and returns real
84          number.
85        - Built-in script functions "min()" and "max()" optionally accept real
86          number arguments and return real number as result in that case.
87        - NKSP VM API: Allow units and 'final'ness to be returned as result from
88          built-in functions (added methods VMFunction::returnUnitType() and
89          VMFunction::returnsFinal() for that purpose which must be implemented by
90          built-in function implementations).
91        - NKSP language: Allow metric unit prefixes of numeric scalar and array
92          variables to be changed freely at runtime (unlike unit types like Hz etc.
93          which are still sticky, parse-time features of variables which cannot be
94          changed at runtime for the intentional sake of determinism).
95        - NKSP language: 'final' values are prohibited for array variables for now
96          (attempt causes a parsers error).
97        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
98          conditions of runtime control structures like if(), while(), select()
99          (attempt causes a parser error).
100        - NKSP VM API: Allow built-in functions to perform their own, individual
101          parse time checks of arguments going to be passed to the function at
102          runtime (added method VMFunction::checkArgs() for that purpose).
103        - NKSP language: raise parser warning if only one operand of binary
104          operators (like logical 'or' comparison) contain a 'final' value (because
105          it would always yield in a 'final' result in such cases).
106        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
107          different metric unit prefixes, which will behave as expected (e.g.
108          result of expression '1000us < 2ms' is true).
109        - NKSP language: Allow adding values with different metric unit prefixes
110          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
111        - NKSP language: Allow subtracting values with different metric unit
112          prefixes (e.g. result of expression '1ms - 20us' is '980us').
113        - NKSP language: Allow multiplying with any metric unit prefixes
114          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
115          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
116          we don't have any considerable practical use for a term like '4s^2'
117          (hence any attempt multiplying two unit types still causes parser error).
118        - NKSP language: Allow dividing by any metric unit prefixes and allow
119          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
120          yields in unit free result '8'). So this is now a way to cast units away
121          e.g. for passing the result to other expressions, certain function calls
122          or variables which are not accepting any units (or that specific unit).
123        - NKSP language: integer arrays and real number arrays can now be converted
124          to strings (e.g. for dumping their content with message() calls for
125          script debugging purposes).
126        - NKSP language: expressions and variables with units are now correctly
127          casted to strings (e.g. with message() calls).
128        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
129          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
130          floating point tolerances into account.
131        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
132          VMScalarNumberExpr::evalCastReal().
133        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
134          'VMIntArrayExpr' and 'VMRealArrayExpr'.
135        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
136          unitFactor() (runtime) methods.
137        - Built-in function "exit()" supports now returning units and 'final'ness
138          for test cases.
139        - The following built-in functions support now units as well: "abs()",
140          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
141          "real_to_int()", "int()", "int_to_real()" and "real()".
142        - Built-in functions "array_equal()", "search()" and "sort()" support now
143          real number arrays (correctly) as well.
144        - Added individual parse time checks of arguments to be passed to built-in
145          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
146          "array_equal()" and "search()" specific for their individual purposes.
147        - NKSP VM refactoring: Renamed all methods, functions and classes matching
148          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
149          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
150          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
151          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
152          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
153          isScalarNumber() -> isNumber()).
154        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
155          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
156          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
157          as convenient methods for automatically converting values to expected
158          metric value basis.
159        - Built-in function "wait()" accepts now both integers and real numbers as
160          argument.
161        - NKSP VM API cleanup: Get rid of legacy method
162          VMFunction::argType(vmint iArg) which was already superseded by its new
163          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
164        - NKSP parser: if wrong argument type was passed to a built-in function and
165          that built-in function accepts more than one data type for the argument,
166          then show all supported data types as parser error message.
167        - Built-in function "play_note()" accepts now real numbers and seconds as
168          unit type as well for its 3rd and 4th function arguments.
169        - The following built-in functions accept now real numbers as well for their
170          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
171          "change_attack()", "change_decay()", "change_release()",
172          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
173          "change_cutoff_sustain()", "change_cutoff_release()",
174          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
175          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
176          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
177        - Fixed built-in function "change_play_pos()" not having accepted metric
178          prefixes at all.
179        - Fixed the following built-in functions having misinterpreted values given
180          with unit type (for their 2nd argument) as if they were relative values
181          (that is as if they were passed without a unit type): "change_attack()",
182          "change_decay()", "change_release()", "change_cutoff_attack()",
183          "change_cutoff_decay()", "change_cutoff_release()".
184        - Fixed the following built-in functions having applied completely wrong
185          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
186          respective EGs being their modulation sink assume uint data type with
187          value range 0..1000 instead of 0.0..1.0.
188        - Added individual parse-time checks of function arguments for the following
189          built-in functions: "play_note()", "note_off()", "set_event_mark()",
190          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
191          "change_decay()", "change_release()", "change_cutoff_attack()",
192          "change_cutoff_decay()", "change_cutoff_release()",
193          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
194          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
195          "change_pan_time()".
196        - Don't abort function call if unit type was used and at the same time
197          'final' operator was omitted for the primary value argument of the
198          following built-in functions: "change_cutoff()", "change_attack()",
199          "change_decay()", "change_release()", "change_cutoff_attack()",
200          "change_cutoff_decay()", "change_cutoff_release()",
201          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
202          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
203          "change_pan_time()", instead imply 'final'ness at runtime and raise an
204          appropriate parser warning at parse time.
205        - Added built-in real number functions "round()", "ceil()", "floor()",
206          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
207          "cos()", "tan()", "asin()", "acos()", "atan()".
208        - Added built-in script real number constant "~NI_MATH_PI".
209        - Added built-in script real number constant "~NI_MATH_E".
210        - NKSP language: Allow unary '+' operator.
211        - Added built-in script functions "msb()" and "lsb()".
212    
213      * test cases:
214        - Fixed compiler errors in test cases.
215        - Updated README for how to compile & run test cases.
216        - Updated test case
217          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
218          expected behaviour of the Mutex class implementation (recursive
219          mutex type).
220        - Added test cases for NKSP core language aspects and core built-in
221          functions.
222        - Fixed thread tests segfaulting on Linux.
223        - NKSP: Added real number test cases for built-in functions exit(),
224          int_to_real(), real(), real_to_int() and int(), as well as for the
225          plus, minus and negate language operators.
226        - Added massive amount of NKSP test cases for standard measuring units and
227          'final' operator usage cases.
228        - Added NKSP test cases for (floating point tolerance aware) real number
229          equalness / unequalness comparison.
230        - Added NKSP int array and real array tests for value assignment and
231          initialization of arrays.
232        - Added NKSP test cases for built-in functions "round()", "ceil()",
233          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
234          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
235        - Added NKSP test cases for unary '+' operator.
236    
237      * GigaStudio/Gigasampler format engine:
238        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
239          behaviour for start_level_mid.
240        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
241          level (see discussion "GigaStudio LFO compatibility" on mailing list
242          from 2019-09-26 for details).
243        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
244          see discussion "GigaStudio LFO compatibility" on mailing list from
245          2019-09-26 for details).
246        - Format extension: Added support for different LFO wave forms (currently
247          either sine [default], triangle, saw or square).
248        - Format extension: Added support for LFO phase displacement (0°..360°).
249        - Format extension: Added support for flipping LFO polarity on LFO 3
250          (in the original gig format this was only available for LFO 1 and LFO 2).
251        - Format extension: Support for additional filter types:
252          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
253          bandreject 2-pole.
254    
255      * SFZ format engine:
256        - Fixed support for regions with loccN/hiccN conditions on more than one
257          MIDI controller.
258    
259      * Benchmarks:
260        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
261          algorithm (since result of 2nd run was not accumulated).
262        - Added benchmark for saw wave (benchmarks/saw.cpp).
263        - Added benchmark for sine wave (benchmarks/sine.cpp).
264        - Added benchmark for square wave (benchmarks/square.cpp).
265        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
266          which are large enough on modern systems.
267    
268    Version 2.1.1 (27 Jul 2019)
269    
270      * Real-time instrument scripts:
271        - Fixed behavior of built-in NKSP functions change_sustain(),
272          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
273          and change_cutoff_release().
274    
275      * general changes:
276        - Only play release trigger samples on sustain pedal up if this behaviour
277          was explicitly requested by the instrument (otherwise only on note-off).
278        - Fixed compiler warnings.
279        - Fixed compilation error when cross-compiling to Mac.
280        - FX Sends: Provide more useful error messages on routing problems
281          (see bug #169).
282        - LSCP doc: Be more clear describing the two distinct approaches
283          of using external vs. internal effects (see bug #169).
284        - "optional" class: Fixed comparison operators.
285    
286      * Gigasampler/GigaStudio format engine:
287        - Format extension: If requested by instrument then don't play release
288          trigger sample on note-off events.
289    
290      * SFZ format engine:
291        - Fixed memory leak when releasing samples
292          (fixes bug #307, patch by Jacek Roszkowski)
293        - Fixed potential crash when a sample is shared by more than one region
294          (fixes bug #308, patch by Jacek Roszkowski).
295        - Opcode 'sample': Added support for built-in sample '*silence'
296          (fixes bug #310, patch by Jacek Roszkowski).
297    
298    Version 2.1.0 (25 Nov 2017)
299    
300      * SFZ format engine:
301        - added support for <global>, <master> and #define (patch by Alby M)
302        - Removed code duplication in SFZ file loading code.
303        - Added support for sfz extension opcode 'script' which may be used to
304          load real-time instrument script file (NKSP script language).
305        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
306        - Fixed unintended volume fade-in of voices under certain conditions.
307        - sfz parser: allow missing space between header and opcode
308    
309      * Gigasampler/GigaStudio format engine:
310        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
311          cutoff settings.
312        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
313          all if an up-pitch of more than 40 semi tones was requested (I don't
314          think there is any stock gig sound that requires this behavior to
315          resemble its original sound).
316        - Added support for controlling whether the individual EGADSR stages may
317          be aborted (as LinuxSampler extension to the original GigaStudio 4
318          format).
319    
320      * general changes:
321        - fixed printf type errors (mostly in debug messages)
322        - use unique_ptr instead of auto_ptr when building with C++11
323        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
324          allowing to sort data efficiently in real-time safe manner.
325        - RTList class: added methods for moving/inserting elements to arbitrary
326          position within a list.
327        - RTList class: added method fromPtr() for creating an Iterator object from
328          a raw element pointer.
329        - Attempt to partly fix resetting engine channels vs. resetting engine, an
330          overall cleanup of the Reset*(), ConnectAudioDevice(),
331          DisconnectAudioDevice() API methods would still be desirable though,
332          because the current situation is still inconsistent and error prone.
333        - Active voices are now internally grouped to "Note" objects, instead of
334          being directly assigned to a keyboard key. This allows more fine graded
335          processing of voices, which is i.e. required for certain instrument
336          script features.
337        - Fix: Release trigger voices were not spawned on sustain pedal up
338          (CC #64) events.
339        - Fix: Release trigger voices can now also distinguish correctly between
340          note-off and sustain pedal up events.
341        - All engines: Increased ramp speed of volume smoother and pan smoother
342          (while slow rate of crossfade smoother is preserved) to allow quick
343          volume and pan changes by instrument scripts for instance.
344        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
345          properly and thus were ignored for certain uses.
346        - Added new C++ API method
347          VirtualMidiDevice::SendChannelPressureToSampler().
348        - windows, 32-bit: fixed potential crashes by making sure the stack in
349          sub threads is 16-byte aligned
350        - fixed numerous compiler warnings
351        - Fixed invalid (note-on) event ID being assigned to new Note objects.
352        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
353          fixes potential undefined behavior.
354        - Fixed Note object leak when triggering notes on keys which did not
355          have a valid sample mapped (fixes bug #252).
356        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
357        - linuxsampler binary fix: option --create-instruments-db ignored
358          subsequent optional argument due to glibc's implementation oddity
359          which expects a "=" sign, but no space between them.
360    
361      * packaging changes:
362        - removed unnecessary dependency to libuuid
363          (originated by libgig's usage of it)
364        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
365          auto detect whether it (sh/c)ould output its messages in color.
366        - Debian: Fixed packaging error about invalid "Source-Version"
367          substitution variable.
368        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
369        - Debian: Added build dependency to libsqlite3-dev for building
370          linuxsampler with instruments DB support.
371    
372      * Real-time instrument scripts:
373        - Implemented scheduler for delayed MIDI events and for suspended scripts.
374        - Built-in script function "wait()": implemented support for function's
375          "duration-us" argument, thus scripts using this function are now
376          correctly resumed after the requested amount of microseconds.
377        - Built-in script function "play_note()": implemented support for
378          function's "duration-us" argument, thus notes triggered with this
379          argument are now correctly released after the requested amount of
380          microseconds.
381        - Fix: script events were not cleared when engine channel was reset,
382          potentially causing undefined behavior.
383        - Fixed crash which happened when trying to reference an undeclared
384          variable.
385        - Built-in script function "play_note()": Added support for passing
386          special value -1 for "duration-us" argument, which will cause the
387          triggered note to be released once the original note was released.
388        - Instrument script classes now exported with the liblinuxsampler C++ API.
389        - Added new API method ScriptVM::syntaxHighlighting() which provides
390          a convenient syntax highlighting backend for external instrument
391          script editor applications.
392        - Added new C++ API class "ScriptVMFactory".
393        - Extended parser issues to provide not only first line and first
394          column, but also last line and last column of issue (thus marking
395          the precise span of the issue within the source code).
396        - Reload script automatically after being modified by an instrument
397          editor.
398        - NKSP language grammar correction: allow empty event handler bodies
399          like "on note end on".
400        - Implemented built-in script function "change_vol()".
401        - Implemented built-in script function "change_tune()".

405        - Implemented built-in script function "event_status()".
406        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
407          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
408          "event_status()" function.
409        - NKSP language: Added support for bitwise operators ".or.", ".and."
410          and ".not.".
411        - NKSP language scanner: Fixed IDs matching to require at least one
412          character (i.e. when matching function names or variable names).
413        - NKSP language scanner: disabled unusued rules.
414        - Fixed behavior of play_note() and note_off() functions which must
415          be distinguished engine internally from "real" MIDI note on/off
416          events in order to avoid misbehaviors like hanging notes.
417        - Implemented built-in script variable "$KSP_TIMER".
418        - Implemented built-in script variable "$NKSP_REAL_TIMER".
419        - Implemented built-in script variable "$NKSP_PERF_TIMER".
420        - Implemented built-in script variable "$ENGINE_UPTIME".
421        - Implemented built-in script function "inc()".
422        - Implemented built-in script function "dec()".
423        - NKSP language fix: division expressions were evaluated too often.
424        - NKSP language fix: string concatenation operator was right
425          associative instead of left (to right).
426        - NKSP language correction: allow empty statements in entire language
427          (i.e. "if end if").
428        - Implemented built-in script function "stop_wait()".
429        - Implemented built-in script variable "$NI_CALLBACK_ID".
430        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
431        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
432        - Added support for read-only built-in variables (respectively
433          handled by the script parser).
434        - Added built-in script constant "$NI_CB_TYPE_INIT".
435        - Added built-in script constant "$NI_CB_TYPE_NOTE".
436        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

440        - Implemented built-in script function "change_decay()".
441        - Implemented built-in script function "change_release()".
442        - Fixed all change_*() built-in script functions to apply their
443          synthesis parameter changes immediately in case the respective note
444          was triggered at the same time, instead of scheduling the parameter
445          change, especially because it would cause some parameter types's
446          changes either to be ramped (i.e. change_vol()) or other types even
447          to have not effect at all (i.e. change_attack()).
448        - Implemented built-in script function "sh_left()".
449        - Implemented built-in script function "sh_right()".
450        - Implemented built-in script function "min()".
451        - Implemented built-in script function "max()".
452        - NKSP Fix: "init" event handler was not always executed when a script
453          was loaded.
454        - NKSP built-in wait() script function: abort script execution if
455          a negative or zero wait time was passed as argument (since this is
456          a common indication of a bug either of the script or even of the
457          engine, which could lead to RT instability or even worse).
458        - ScriptVM: Implemented automatic suspension of RT safety
459          threatening scripts.
460        - Provide more user friendly error messages on syntax errors.
461        - Fixed NKSP parser warning "Not a statement" when assigning an
462          initializer list to an array variable.
463        - Implemented built-in script array variable "%ALL_EVENTS".
464        - Implemented built-in script function "in_range()".

467        - Implemented built-in script function "change_pitch_lfo_depth()".
468        - Implemented built-in script function "change_pitch_lfo_freq()".
469        - Implemented built-in script function "change_vol_time()".
470        - Implemented built-in script function "change_tune_time()".
471        - Implemented built-in script function "fade_in()".
472        - Implemented built-in script function "fade_out()".
473        - Fixed acceptance of wrong data type of parameters passed to built-in
474          script functions "change_vol()", "change_tune()", "change_pan()",
475          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
476          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
477          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
478        - Added built-in script function "get_event_par()" and implemented some
479          of its possible parameter selections.
480        - Added built-in script function "set_event_par()" and implemented some
481          of its possible parameter selections.
482        - Fixed a bunch of scheduler time related bugs.
483        - Fixed polyphonic variables not being reset to zero after usage.
484        - Built-in "ignore_event()" function: argument is now optional, like with
485          built-in function "ignore_controller()".
486        - Implemented built-in script function "change_velo()".
487        - Implemented built-in script function "change_note()".
488        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
489          intuitive behavior if used in combination with "change_vol_time()" or
490          "change_tune_time()" respectively: now tuning/volume changes are only
491          assigned (without delay) immediately to a new note if the respective
492          timing function has not been called before, otherwise the volume/tuning
493          changes are automatically faded (before, only the event's time stamp was
494          relevant).
495         - Implemented built-in script function "array_equal()".
496         - Implemented built-in script function "search()".
497         - Implemented built-in script function "sort()".
498         - NKSP Fix: Never suspend "init" event handlers.
499         - Implemented built-in script function "same_region()" (currently only
500           available for gig format engine).
501         - Added built-in script constant "$NKSP_LINEAR".
502         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
503         - Implemented built-in script function "change_vol_curve()".
504         - Implemented built-in script function "change_tune_curve()".
505         - built-in "play_note()" function now supports a sample playback start
506           offset with argument 3, where special value -1 means to use the regular
507           sample offset as defined by the instrument file.
508         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
509         - Built-in variable $EVENT_NOTE is now a read-only variable.
510         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
511         - built-in "play_note()" function now accepts -2 for its fourth argument
512           (note duration) which means the life time of the note shall be sticked
513           to the requested note number of argument 1.
514         - Fix: built-in "play_note()" function now returns 0 as result value if
515           -1 was passed for its fourth argument (note duration) and the respective
516           parent note is already gone.
517        - Implemented built-in script function "change_play_pos()".
518        - NKSP language: Added support for user declared const array variables.
519        - NKSP language: Raise parser warning if array variable is accessed with
520          an index that exceeds the array's size.
521        - NKSP language fix: Unknown characters were not handled correctly.
522        - NKSP language: Added support for "synchronized .. end synchronized"
523          code blocks.
524        - Implemented built-in script function "abort()" which allows to abort
525          another script handler by passing its callback ID.
526        - Fixed potential memory access bug and potential undefined behavior of
527          "init" event handlers.
528        - Print a time stamp along to each call of built-in function "message()".
529        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
530          to retrieve all code blocks filtered out by the preprocessor.
531        - Added built-in script function "fork()".
532        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
533        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
534        - Fixed potential crash when accessing dynamic built-in array variables.
535        - Added built-in script function "callback_status()".
536        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
537        - Added built-in constant $CALLBACK_STATUS_QUEUE.
538        - Added built-in constant $CALLBACK_STATUS_RUNNING.
539        - Removed max. value limitation of built-in functions "change_attack()",
540          "change_decay()" and "change_release()" to i.e. allow passing 2000000
541          for doubling the respective time.
542        - NKSP script editor syntax highlighting API: Fixed app termination due
543          to a lexer start condition stack underrun.
544        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
545          USE_CODE_IF_NOT() preprocessor statements.
546        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
547          can be set to disable all subsequent built-in "message()" function calls
548          on preprocessor level.
549        - Implemented built-in script function "change_sustain()".
550        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
551          to avoid the editor app to crash on ill-formed text input.
552        - Added built-in script function "change_pan_time()".
553        - Added built-in script function "change_pan_curve()".
554        - Added built-in script function "change_cutoff_attack()".
555        - Added built-in script function "change_cutoff_decay()".
556        - Added built-in script function "change_cutoff_sustain()".
557        - Added built-in script function "change_cutoff_release()".
558        - Added built-in script function "change_cutoff_lfo_depth()".
559        - Added built-in script function "change_cutoff_lfo_freq()".
560    
561      * Instruments DB:
562        - Fixed memory access bug of general DB access code which lead to
563          undefined behavior.
564        - Cleanup of instruments DB file creation and opening code.
565        - The instrument DB path of linuxsampler's --create-instruments-db argument
566          is now optional, if it is missing, then a default location is used.
567        - Added support for scanning SFZ (.sfz) files.
568        - Added support for scanning Sound Font (.sf2) files.
569        - Fixed undefined DB transaction behavior.
570    
571    Version 2.0.0 (15 July 2015)

574        - fixed building with newer MinGW-w64
575        - Mac OS X: support the new dir for Core Audio SDK
576        - Mac OS X: fixed building outside source directory
577        - made sure all source files for hostplugins are included when
578          doing "make dist"
579        - removed empty directories left from the cvs to svn migration
580        - fixed compilation with gcc 4.6.1
581        - another "make dist" fix, for the LV2 plugin
582        - made --enable-pthread-testcancel default on Mac OS X
583        - minor Makefile fix for building lscpparser when build and source
584          directories are separate
585        - Mac OS X: made it possible to specify plugin installation dir to
586          configure
587        - Mac OS X: Makefile fix for the install-strip target
588        - fixed compilation with gcc 4.7
589        - fixed configure script error with old autoconf versions
590        - lsatomic.h: use gcc provided atomic functions if building with
591          gcc 4.7 and C++11
592        - modernized configure script
593        - fixed linkage error when building with
594          LDFLAGS="-Wl,--no-undefined" (#190)
595        - fixed compilation with Clang 3.2

603          on the process's main thread
604        - fixed build error on newer MinGW
605        - support building with older jack versions
606        - support building with spaces in vst sdk path
607        - enabled automake 'subdir-objects' option and moved external
608          source references (vst, au, asio) from makefiles to cpp files,
609          in order to get rid of warnings from automake 1.14
610    
611      * general changes:
612        - Refactoring: moved the independent code from
613          the Gigasampler format engine to base classes
614        - command line option '--profile' is currently disabled, since the
615          respective profiling code is currently broken
616        - Introduced support for optional environment variable
617          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
618          where the sampler shall look for instrument editor plugins
619          (patch by Luis Garrido, slightly modified).
620        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
621        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
622        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
623          note (in this implementation of the sampler its simply hard routed to
624          the 1st effect send of the sampler channel, no matter what the actual
625          effect type is)
626        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
627          note (in this implementation of the sampler its simply hard routed to
628          the 2nd effect send of the sampler channel, no matter what the actual
629          effect type is)
630        - implemented support for internal LADSPA effects
631        - raised limit of program change queue from 100 to 512
632          (as suggested by Alex Stone)
633        - implemented sine LFO, pulse LFO and saw LFO
634        - experimental support for per voice equalization
635        - added command line option --exec-after-init
636        - Introduced new C++ API method:
637          EngineChannel::InstrumentFileName(int index)
638          allowing to retrieve the whole list of files used for the loaded
639          instrument on an engine channel (a.k.a. part). Some GigaStudio
640          instruments for example are splitted over several files like
641          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
642        - Added new C++ API method Sampler::GetGlobalMaxVoices().
643        - Added new C++ API method Sampler::GetGlobalMaxStreams().
644        - Added new C++ API method Sampler::SetGlobalMaxVoices().
645        - Added new C++ API method Sampler::SetGlobalMaxStreams().
646        - Various "const" and "restrict" optimizations.
647        - all engines: add pan CC value to instrument pan parameter before
648          applying panning, instead of using two separate pan functions in
649          series (#182)
650        - added a lock guard class for exception safe mutex handling and
651          used it everywhere appropriate
652        - Immediately apply scale tuning changes to active voices.
653        - Exposed scale tuning to C++ API (along to the already existing standard
654          SysEx way).
655        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
656          and broken for ppc64. (Seq_cst loads and stores are actually not
657          used in LS, so the bug wasn't noticable.)
658        - lsatomic.h: added ARMv7 support
659        - Added support for multiple MIDI input ports per sampler channel (and
660          added various new C++ methods for this new feature / design change, old
661          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
662          as deprecated but are still there and should provide full behavior
663          backward compatibility).
664        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
665          unsafe and caused compilation error with clang 2.x).
666        - Bugfix: only process the latest MIDI program change event.
667        - Introducing the LSCP shell, which provides convenient control of the
668          sampler from the command line by providing LSCP aware features.
669        - VirtualMidiDevice: Added support for program change.
670        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
671        - VirtualMidiDevice: Added support for pitch bend.
672        - Aftertouch: extended API to explicitly handle channel pressure and
673          polyphonic key pressure events (so far polyphonic pressure was not
674          supported at all, and channel pressure was rerouted as CC128 but not
675          used so far).
676        - Added initial support for real-time instrument scripts. The script VM
677          code is shared by all sampler engine implemementations, however only the
678          gig file format currently provides support for storing instrument scripts
679          (as LinuxSampler extension to the original GigaStudio 4 format).
680    
681      * Gigasampler format engine:
682        - implemented the "round robin keyboard" dimension
683        - fixed round robin and random dimensions for cases when number of
684          dimension zones is not a power of two
685        - made round robin use a counter for each region instead of each
686          key
687        - bugfix: pitch LFO controller "internal+aftertouch" was broken
688        - bugfix: filter keyboard tracking was broken
689        - filter performance fix (an unnecessary copy was made of the
690          filter parameters in each sub fragment)
691        - handle special case when pan parameter in gig file has max or
692          min value
693        - Exclusive Groups: don't ever stop voices of the same note,
694          doesn't sound naturally with a drumkit
695        - fixed EG1 modulation when attack or release is zero
696        - Fixed support for 'aftertouch' attenuation controller.
697        - Fixed crash that happened with velocity split sounds under certain
698          conditions (see also previous commit on libgig).
699        - fixed behaviour of filter LFO
700    
701      * SFZ format engine:
702        - Initial implementation (not usable yet)
703        - added support for v2 multiple stage envelope generators
704        - added a fine-tuned v1 envelope generator instead of using the
705          one from the gig engine
706        - fixed memory leak and memory handling errors
707        - added support for trigger=first, trigger=legato and sw_previous
708        - allow non-numerical key values ("C#4" for example)
709        - "key" opcode now sets pitch_keycenter too
710        - fixed error when unloading instrument with same sample used by
711          multiple regions
712        - added some opcode aliases, like loopmode for loop_mode, to be

1042        - Giga format scripts: Implemented built-in script function
1043          "gig_set_dim_zone(event_id, dimension, zone)".
1044        - Implemented built-in script int array variable %KEY_DOWN.
1045        - Implemented built-in script function "abs()".
1046        - Implemented built-in script function "random()".
1047        - Implemented built-in script function "num_elements()".
1048        - Implemented built-in script function "note_off()".

1053        - Built-in script functions "ignore_event()", "note_off()" and
1054          "gig_set_dim_zone()" now also accept an array of event IDs as argument
1055          (i.e. return value of new script function "by_marks()").
1056        - Pass/preserve polyphonic variable data from respective "note" event
1057          handler to "release" event handler.
1058        - Fixed crash when using built-in script function "by_marks()".
1059    
1060      * Bug fixes:
1061        - Fixed crash which may occur when MIDI key + transpose is out of range
1062        - minor valgrind fixes
1063        - fixed crash which occurred when changing an already deployed sampler
1064          channel to a different engine type
1065        - fixed crash when deleting a sampler channel or changing engine
1066          type while an instrument load was in progress
1067        - bugfix: playing a note while changing the instrument could cause
1068          a crash, or give "Handing back unknown region" error messages
1069        - bugfix: calling SET VOICES (which Fantasia does on start and
1070          refresh) could cause instruments to be unloaded
1071        - Mac OS X: fixed name collision of enum in EffectControl and
1072          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1073        - Mac OS X: fixed hanging threads
1074        - Windows: disabled the previous thread fix on non-Mac systems, as
1075          it caused hanging threads on Windows
1076        - Fixed possible crashes due to corrupted MIDI/audio device list
1077          after MIDI/audio device creation failure
1078        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1079          instruments were uselessly precached with zero samples, however it still
1080          took the full preloading time and on 1st program change the respective
1081          instrument was completely reloaded again.
1082        - fixed handling of rapid bank select and program change messages
1083          sent to the same sampler channel (patch from the Open Octave
1084          project, slightly adjusted)
1085        - fixed crash when trying to create an effect instance with controls
1086          which min and/or max values depend on the sample rate
1087        - fixed bug #162
1088        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1089          multiple paths (#165)
1090        - thread safety fixes for the instrument loading thread
1091        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1092          (#176)
1093        - more thread safety fixes for the instrument loading thread
1094        - sfz/sf2 engine: fixed crash when using small audio fragment size
1095        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1096        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1097          introduced in previous fix)
1098        - fixed crash when a channel received a program change while
1099          playing a note in a key group
1100        - fixed erroneous error message piping in VoiceBase.h
1101          (labelled "Disk stream not available in time")
1102        - Update effects on sample rate & period size changes (to avoid
1103          crashes and noise on such transitions).
1104        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1105          (fixes #208)
1106        - Fixed bug in LSCP grammar definition which caused a statement like
1107          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1108          practically irrelevant, however it caused problems with the new LSCP
1109          shell's auto completion feature).
1110        - Fixed MIDI program change messages being ignored if quickly executed
1111          after each other (fixes #231).
