# 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    
32      * Real-time instrument scripts:
33        - Added method ScriptVM::setExitResultEnabled() which allows to
34          explicitly enable the built-in exit() function to optionally accept
35          one function argument; the value of the passed exit() function
36          argument will then become available by calling
37          VMExecContext::exitResult() after script execution.
38        - 64 bit support for NKSP integer scripts variables (declare $foo).
39        - Variable names, function names and preprocessor condition names must start
40          with a regular character (a-z or A-Z); starting them with a digit or
41          underscore is not allowed.
42        - NKSP parser fix: equal comparison operator "=" and not equal comparison
43          operator "#" must only accept integer operands.
44        - NKSP language: Implemented support for standard units like Hertz, seconds,
45          Bel including support for metric unit prefixes; so one can now e.g.
46          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
47          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
48          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
49        - NKSP language: Introduced "final" operator "!" which is specifically
50          intended for synthesis parameter values to denote that the synthesis
51          parameter value is intended to be the "final" value for that synthesis
52          parameter that should explicitly be used by the engine and thus causing
53          the sampler engine to ignore all other modulation sources for the same
54          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
55          variable or formula with this new "!" operator the expression is marked as
56          being "final".
57        - NKSP script editor API: Added support for detecting standard unit tokens
58          and their potential metric prefix token.
59        - NKSP language: Added support for NKSP real number literals and
60          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
61        - NKSP language: Added support for NKSP real number (floating point) script
62          variables (declare ~foo).
63        - NKSP language: Added support for NKSP real number (floating point) array
64          script variables (declare ?foo[]).
65        - Built-in script function "message()" accepts now real number argument as
66          well.
67        - Added built-in script function "real_to_int()" and its short hand form
68          "int()" for casting from real number to integer in NKSP scripts.
69        - Added built-in script function "int_to_real()" and its short hand form
70          "real()" for casting from integer to real number in NKSP scripts.
71        - Allow built-in exit() function to potentially accept real number type
72          argument as well.
73        - Built-in script functions may have a different return type depending on
74          the arguments passed to the function.
75        - Built-in script function "abs()" optionally accepts and returns real
76          number.
77        - Built-in script functions "min()" and "max()" optionally accept real
78          number arguments and return real number as result in that case.
79        - NKSP VM API: Allow units and 'final'ness to be returned as result from
80          built-in functions (added methods VMFunction::returnUnitType() and
81          VMFunction::returnsFinal() for that purpose which must be implemented by
82          built-in function implementations).
83        - NKSP language: Allow metric unit prefixes of numeric scalar and array
84          variables to be changed freely at runtime (unlike unit types like Hz etc.
85          which are still sticky, parse-time features of variables which cannot be
86          changed at runtime for the intentional sake of determinism).
87        - NKSP language: 'final' values are prohibited for array variables for now
88          (attempt causes a parsers error).
89        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
90          conditions of runtime control structures like if(), while(), select()
91          (attempt causes a parser error).
92        - NKSP VM API: Allow built-in functions to perform their own, individual
93          parse time checks of arguments going to be passed to the function at
94          runtime (added method VMFunction::checkArgs() for that purpose).
95        - NKSP language: raise parser warning if only one operand of binary
96          operators (like logical 'or' comparison) contain a 'final' value (because
97          it would always yield in a 'final' result in such cases).
98        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
99          different metric unit prefixes, which will behave as expected (e.g.
100          result of expression '1000us < 2ms' is true).
101        - NKSP language: Allow adding values with different metric unit prefixes
102          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
103        - NKSP language: Allow subtracting values with different metric unit
104          prefixes (e.g. result of expression '1ms - 20us' is '980us').
105        - NKSP language: Allow multiplying with any metric unit prefixes
106          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
107          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
108          we don't have any considerable practical use for a term like '4s^2'
109          (hence any attempt multiplying two unit types still causes parser error).
110        - NKSP language: Allow dividing by any metric unit prefixes and allow
111          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
112          yields in unit free result '8'). So this is now a way to cast units away
113          e.g. for passing the result to other expressions, certain function calls
114          or variables which are not accepting any units (or that specific unit).
115        - NKSP language: integer arrays and real number arrays can now be converted
116          to strings (e.g. for dumping their content with message() calls for
117          script debugging purposes).
118        - NKSP language: expressions and variables with units are now correctly
119          casted to strings (e.g. with message() calls).
120        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
121          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
122          floating point tolerances into account.
123        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
124          VMScalarNumberExpr::evalCastReal().
125        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
126          'VMIntArrayExpr' and 'VMRealArrayExpr'.
127        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
128          unitFactor() (runtime) methods.
129        - Built-in function "exit()" supports now returning units and 'final'ness
130          for test cases.
131        - The following built-in functions support now units as well: "abs()",
132          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
133          "real_to_int()", "int()", "int_to_real()" and "real()".
134        - Built-in functions "array_equal()", "search()" and "sort()" support now
135          real number arrays (correctly) as well.
136        - Added individual parse time checks of arguments to be passed to built-in
137          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
138          "array_equal()" and "search()" specific for their individual purposes.
139        - NKSP VM refactoring: Renamed all methods, functions and classes matching
140          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
141          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
142          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
143          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
144          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
145          isScalarNumber() -> isNumber()).
146        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
147          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
148          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
149          as convenient methods for automatically converting values to expected
150          metric value basis.
151        - Built-in function "wait()" accepts now both integers and real numbers as
152          argument.
153        - NKSP VM API cleanup: Get rid of legacy method
154          VMFunction::argType(vmint iArg) which was already superseded by its new
155          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
156        - NKSP parser: if wrong argument type was passed to a built-in function and
157          that built-in function accepts more than one data type for the argument,
158          then show all supported data types as parser error message.
159        - Built-in function "play_note()" accepts now real numbers and seconds as
160          unit type as well for its 3rd and 4th function arguments.
161        - The following built-in functions accept now real numbers as well for their
162          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
163          "change_attack()", "change_decay()", "change_release()",
164          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
165          "change_cutoff_sustain()", "change_cutoff_release()",
166          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
167          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
168          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
169        - Fixed built-in function "change_play_pos()" not having accepted metric
170          prefixes at all.
171        - Fixed the following built-in functions having misinterpreted values given
172          with unit type (for their 2nd argument) as if they were relative values
173          (that is as if they were passed without a unit type): "change_attack()",
174          "change_decay()", "change_release()", "change_cutoff_attack()",
175          "change_cutoff_decay()", "change_cutoff_release()".
176        - Fixed the following built-in functions having applied completely wrong
177          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
178          respective EGs being their modulation sink assume uint data type with
179          value range 0..1000 instead of 0.0..1.0.
180        - Added individual parse-time checks of function arguments for the following
181          built-in functions: "play_note()", "note_off()", "set_event_mark()",
182          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
183          "change_decay()", "change_release()", "change_cutoff_attack()",
184          "change_cutoff_decay()", "change_cutoff_release()",
185          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
187          "change_pan_time()".
188        - Don't abort function call if unit type was used and at the same time
189          'final' operator was omitted for the primary value argument of the
190          following built-in functions: "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()",
195          "change_pan_time()", instead imply 'final'ness at runtime and raise an
196          appropriate parser warning at parse time.
197        - Added built-in real number functions "round()", "ceil()", "floor()",
198          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
199          "cos()", "tan()", "asin()", "acos()", "atan()".
200        - Added built-in script real number constant "~NI_MATH_PI".
201        - Added built-in script real number constant "~NI_MATH_E".
202        - NKSP language: Allow unary '+' operator.
203    
204      * test cases:
205        - Fixed compiler errors in test cases.
206        - Updated README for how to compile & run test cases.
207        - Updated test case
208          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
209          expected behaviour of the Mutex class implementation (recursive
210          mutex type).
211        - Added test cases for NKSP core language aspects and core built-in
212          functions.
213        - Fixed thread tests segfaulting on Linux.
214        - NKSP: Added real number test cases for built-in functions exit(),
215          int_to_real(), real(), real_to_int() and int(), as well as for the
216          plus, minus and negate language operators.
217        - Added massive amount of NKSP test cases for standard measuring units and
218          'final' operator usage cases.
219        - Added NKSP test cases for (floating point tolerance aware) real number
220          equalness / unequalness comparison.
221        - Added NKSP int array and real array tests for value assignment and
222          initialization of arrays.
223        - Added NKSP test cases for built-in functions "round()", "ceil()",
224          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
225          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
226        - Added NKSP test cases for unary '+' operator.
227    
228      * GigaStudio/Gigasampler format engine:
229        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
230          behaviour for start_level_mid.
231        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
232          level (see discussion "GigaStudio LFO compatibility" on mailing list
233          from 2019-09-26 for details).
234        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
235          see discussion "GigaStudio LFO compatibility" on mailing list from
236          2019-09-26 for details).
237        - Format extension: Added support for different LFO wave forms (currently
238          either sine [default], triangle, saw or square).
239        - Format extension: Added support for LFO phase displacement (0°..360°).
240        - Format extension: Added support for flipping LFO polarity on LFO 3
241          (in the original gig format this was only available for LFO 1 and LFO 2).
242    
243      * SFZ format engine:
244        - Fixed support for regions with loccN/hiccN conditions on more than one
245          MIDI controller.
246    
247      * Benchmarks:
248        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
249          algorithm (since result of 2nd run was not accumulated).
250        - Added benchmark for saw wave (benchmarks/saw.cpp).
251        - Added benchmark for sine wave (benchmarks/sine.cpp).
252        - Added benchmark for square wave (benchmarks/square.cpp).
253        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
254          which are large enough on modern systems.
255    
256    Version 2.1.1 (27 Jul 2019)
257    
258      * Real-time instrument scripts:
259        - Fixed behavior of built-in NKSP functions change_sustain(),
260          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
261          and change_cutoff_release().
262    
263      * general changes:
264        - Only play release trigger samples on sustain pedal up if this behaviour
265          was explicitly requested by the instrument (otherwise only on note-off).
266        - Fixed compiler warnings.
267        - Fixed compilation error when cross-compiling to Mac.
268        - FX Sends: Provide more useful error messages on routing problems
269          (see bug #169).
270        - LSCP doc: Be more clear describing the two distinct approaches
271          of using external vs. internal effects (see bug #169).
272        - "optional" class: Fixed comparison operators.
273    
274      * Gigasampler/GigaStudio format engine:
275        - Format extension: If requested by instrument then don't play release
276          trigger sample on note-off events.
277    
278      * SFZ format engine:
279        - Fixed memory leak when releasing samples
280          (fixes bug #307, patch by Jacek Roszkowski)
281        - Fixed potential crash when a sample is shared by more than one region
282          (fixes bug #308, patch by Jacek Roszkowski).
283        - Opcode 'sample': Added support for built-in sample '*silence'
284          (fixes bug #310, patch by Jacek Roszkowski).
285    
286    Version 2.1.0 (25 Nov 2017)
287    
288      * SFZ format engine:
289        - added support for <global>, <master> and #define (patch by Alby M)
290        - Removed code duplication in SFZ file loading code.
291        - Added support for sfz extension opcode 'script' which may be used to
292          load real-time instrument script file (NKSP script language).
293        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
294        - Fixed unintended volume fade-in of voices under certain conditions.
295        - sfz parser: allow missing space between header and opcode
296    
297      * Gigasampler/GigaStudio format engine:
298        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
299          cutoff settings.
300        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
301          all if an up-pitch of more than 40 semi tones was requested (I don't
302          think there is any stock gig sound that requires this behavior to
303          resemble its original sound).
304        - Added support for controlling whether the individual EGADSR stages may
305          be aborted (as LinuxSampler extension to the original GigaStudio 4
306          format).
307    
308      * general changes:
309        - fixed printf type errors (mostly in debug messages)
310        - use unique_ptr instead of auto_ptr when building with C++11
311        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
312          allowing to sort data efficiently in real-time safe manner.
313        - RTList class: added methods for moving/inserting elements to arbitrary
314          position within a list.
315        - RTList class: added method fromPtr() for creating an Iterator object from
316          a raw element pointer.
317        - Attempt to partly fix resetting engine channels vs. resetting engine, an
318          overall cleanup of the Reset*(), ConnectAudioDevice(),
319          DisconnectAudioDevice() API methods would still be desirable though,
320          because the current situation is still inconsistent and error prone.
321        - Active voices are now internally grouped to "Note" objects, instead of
322          being directly assigned to a keyboard key. This allows more fine graded
323          processing of voices, which is i.e. required for certain instrument
324          script features.
325        - Fix: Release trigger voices were not spawned on sustain pedal up
326          (CC #64) events.
327        - Fix: Release trigger voices can now also distinguish correctly between
328          note-off and sustain pedal up events.
329        - All engines: Increased ramp speed of volume smoother and pan smoother
330          (while slow rate of crossfade smoother is preserved) to allow quick
331          volume and pan changes by instrument scripts for instance.
332        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
333          properly and thus were ignored for certain uses.
334        - Added new C++ API method
335          VirtualMidiDevice::SendChannelPressureToSampler().
336        - windows, 32-bit: fixed potential crashes by making sure the stack in
337          sub threads is 16-byte aligned
338        - fixed numerous compiler warnings
339        - Fixed invalid (note-on) event ID being assigned to new Note objects.
340        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
341          fixes potential undefined behavior.
342        - Fixed Note object leak when triggering notes on keys which did not
343          have a valid sample mapped (fixes bug #252).
344        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
345        - linuxsampler binary fix: option --create-instruments-db ignored
346          subsequent optional argument due to glibc's implementation oddity
347          which expects a "=" sign, but no space between them.
348    
349      * packaging changes:
350        - removed unnecessary dependency to libuuid
351          (originated by libgig's usage of it)
352        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
353          auto detect whether it (sh/c)ould output its messages in color.
354        - Debian: Fixed packaging error about invalid "Source-Version"
355          substitution variable.
356        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
357        - Debian: Added build dependency to libsqlite3-dev for building
358          linuxsampler with instruments DB support.
359    
360      * Real-time instrument scripts:
361        - Implemented scheduler for delayed MIDI events and for suspended scripts.
362        - Built-in script function "wait()": implemented support for function's
363          "duration-us" argument, thus scripts using this function are now
364          correctly resumed after the requested amount of microseconds.
365        - Built-in script function "play_note()": implemented support for
366          function's "duration-us" argument, thus notes triggered with this
367          argument are now correctly released after the requested amount of
368          microseconds.
369        - Fix: script events were not cleared when engine channel was reset,
370          potentially causing undefined behavior.
371        - Fixed crash which happened when trying to reference an undeclared
372          variable.
373        - Built-in script function "play_note()": Added support for passing
374          special value -1 for "duration-us" argument, which will cause the
375          triggered note to be released once the original note was released.
376        - Instrument script classes now exported with the liblinuxsampler C++ API.
377        - Added new API method ScriptVM::syntaxHighlighting() which provides
378          a convenient syntax highlighting backend for external instrument
379          script editor applications.
380        - Added new C++ API class "ScriptVMFactory".
381        - Extended parser issues to provide not only first line and first
382          column, but also last line and last column of issue (thus marking
383          the precise span of the issue within the source code).
384        - Reload script automatically after being modified by an instrument
385          editor.
386        - NKSP language grammar correction: allow empty event handler bodies
387          like "on note end on".
388        - Implemented built-in script function "change_vol()".
389        - Implemented built-in script function "change_tune()".

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

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

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

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

592        - fixed build error on newer MinGW
593        - support building with older jack versions
594        - support building with spaces in vst sdk path
595        - enabled automake 'subdir-objects' option and moved external
596          source references (vst, au, asio) from makefiles to cpp files,
597          in order to get rid of warnings from automake 1.14
598    
599      * general changes:
600        - Refactoring: moved the independent code from
601          the Gigasampler format engine to base classes
602        - command line option '--profile' is currently disabled, since the
603          respective profiling code is currently broken
604        - Introduced support for optional environment variable
605          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
606          where the sampler shall look for instrument editor plugins
607          (patch by Luis Garrido, slightly modified).
608        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
609        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
610        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
611          note (in this implementation of the sampler its simply hard routed to
612          the 1st effect send of the sampler channel, no matter what the actual
613          effect type is)
614        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
615          note (in this implementation of the sampler its simply hard routed to
616          the 2nd effect send of the sampler channel, no matter what the actual
617          effect type is)
618        - implemented support for internal LADSPA effects
619        - raised limit of program change queue from 100 to 512
620          (as suggested by Alex Stone)
621        - implemented sine LFO, pulse LFO and saw LFO
622        - experimental support for per voice equalization
623        - added command line option --exec-after-init
624        - Introduced new C++ API method:
625          EngineChannel::InstrumentFileName(int index)
626          allowing to retrieve the whole list of files used for the loaded
627          instrument on an engine channel (a.k.a. part). Some GigaStudio
628          instruments for example are splitted over several files like
629          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
630        - Added new C++ API method Sampler::GetGlobalMaxVoices().
631        - Added new C++ API method Sampler::GetGlobalMaxStreams().
632        - Added new C++ API method Sampler::SetGlobalMaxVoices().
633        - Added new C++ API method Sampler::SetGlobalMaxStreams().
634        - Various "const" and "restrict" optimizations.
635        - all engines: add pan CC value to instrument pan parameter before
636          applying panning, instead of using two separate pan functions in
637          series (#182)
638        - added a lock guard class for exception safe mutex handling and
639          used it everywhere appropriate
640        - Immediately apply scale tuning changes to active voices.
641        - Exposed scale tuning to C++ API (along to the already existing standard
642          SysEx way).
643        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
644          and broken for ppc64. (Seq_cst loads and stores are actually not
645          used in LS, so the bug wasn't noticable.)
646        - lsatomic.h: added ARMv7 support
647        - Added support for multiple MIDI input ports per sampler channel (and
648          added various new C++ methods for this new feature / design change, old
649          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
650          as deprecated but are still there and should provide full behavior
651          backward compatibility).
652        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
653          unsafe and caused compilation error with clang 2.x).
654        - Bugfix: only process the latest MIDI program change event.
655        - Introducing the LSCP shell, which provides convenient control of the
656          sampler from the command line by providing LSCP aware features.
657        - VirtualMidiDevice: Added support for program change.
658        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
659        - VirtualMidiDevice: Added support for pitch bend.
660        - Aftertouch: extended API to explicitly handle channel pressure and
661          polyphonic key pressure events (so far polyphonic pressure was not
662          supported at all, and channel pressure was rerouted as CC128 but not
663          used so far).
664        - Added initial support for real-time instrument scripts. The script VM
665          code is shared by all sampler engine implemementations, however only the
666          gig file format currently provides support for storing instrument scripts
667          (as LinuxSampler extension to the original GigaStudio 4 format).
668    
669      * Gigasampler format engine:
670        - implemented the "round robin keyboard" dimension
671        - fixed round robin and random dimensions for cases when number of
672          dimension zones is not a power of two
673        - made round robin use a counter for each region instead of each
674          key
675        - bugfix: pitch LFO controller "internal+aftertouch" was broken
676        - bugfix: filter keyboard tracking was broken
677        - filter performance fix (an unnecessary copy was made of the
678          filter parameters in each sub fragment)
679        - handle special case when pan parameter in gig file has max or
680          min value
681        - Exclusive Groups: don't ever stop voices of the same note,
682          doesn't sound naturally with a drumkit
683        - fixed EG1 modulation when attack or release is zero
684        - Fixed support for 'aftertouch' attenuation controller.
685        - Fixed crash that happened with velocity split sounds under certain
686          conditions (see also previous commit on libgig).
687        - fixed behaviour of filter LFO
688    
689      * SFZ format engine:
690        - Initial implementation (not usable yet)
691        - added support for v2 multiple stage envelope generators
692        - added a fine-tuned v1 envelope generator instead of using the
693          one from the gig engine
694        - fixed memory leak and memory handling errors
695        - added support for trigger=first, trigger=legato and sw_previous
696        - allow non-numerical key values ("C#4" for example)
697        - "key" opcode now sets pitch_keycenter too
698        - fixed error when unloading instrument with same sample used by
699          multiple regions
700        - added some opcode aliases, like loopmode for loop_mode, to be
701          more compatible
702        - added support for trigger=release and rt_decay
703        - added support for off_mode=normal
704        - added support for random, seq_position, seq_length and volume
705        - added v1 LFO opcodes to parser (no support in engine yet)
706        - added support for amp_veltrack and amp_velcurve_N
707        - fine-tuned the default velocity curve
708        - added support for transpose
709        - fixed crash when using sw_down/up
710        - improved logic for sw_lokey/hikey/up/down/last
711        - added more v1 aliases to parser
712        - reduced memory usage for sfz data
713        - RT-safeness: avoid malloc in audio thread
714        - fixed a bug that could cause voice stealing to fail
715        - optimized sample lookup
716        - improved support for exclusive groups (group, off_by and

1050        - minor valgrind fixes
1051        - fixed crash which occurred when changing an already deployed sampler
1052          channel to a different engine type
1053        - fixed crash when deleting a sampler channel or changing engine
1054          type while an instrument load was in progress
1055        - bugfix: playing a note while changing the instrument could cause
1056          a crash, or give "Handing back unknown region" error messages
1057        - bugfix: calling SET VOICES (which Fantasia does on start and
1058          refresh) could cause instruments to be unloaded
1059        - Mac OS X: fixed name collision of enum in EffectControl and
1060          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1061        - Mac OS X: fixed hanging threads
1062        - Windows: disabled the previous thread fix on non-Mac systems, as
1063          it caused hanging threads on Windows
1064        - Fixed possible crashes due to corrupted MIDI/audio device list
1065          after MIDI/audio device creation failure
1066        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1067          instruments were uselessly precached with zero samples, however it still
1068          took the full preloading time and on 1st program change the respective
1069          instrument was completely reloaded again.
1070        - fixed handling of rapid bank select and program change messages
1071          sent to the same sampler channel (patch from the Open Octave
1072          project, slightly adjusted)
1073        - fixed crash when trying to create an effect instance with controls
1074          which min and/or max values depend on the sample rate

1076        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1077          multiple paths (#165)
1078        - thread safety fixes for the instrument loading thread
1079        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1080          (#176)
1081        - more thread safety fixes for the instrument loading thread
1082        - sfz/sf2 engine: fixed crash when using small audio fragment size
1083        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1084        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1085          introduced in previous fix)
1086        - fixed crash when a channel received a program change while
1087          playing a note in a key group
1088        - fixed erroneous error message piping in VoiceBase.h
1089          (labelled "Disk stream not available in time")
1090        - Update effects on sample rate & period size changes (to avoid
1091          crashes and noise on such transitions).
1092        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1093          (fixes #208)
1094        - Fixed bug in LSCP grammar definition which caused a statement like
1095          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1096          practically irrelevant, however it caused problems with the new LSCP
1097          shell's auto completion feature).
1098        - Fixed MIDI program change messages being ignored if quickly executed
1099          after each other (fixes #231).
