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

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

416        - Added built-in script constant "$NI_CB_TYPE_NOTE".
417        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

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

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

555        - fixed building with newer MinGW-w64
556        - Mac OS X: support the new dir for Core Audio SDK
557        - Mac OS X: fixed building outside source directory
558        - made sure all source files for hostplugins are included when
559          doing "make dist"
560        - removed empty directories left from the cvs to svn migration
561        - fixed compilation with gcc 4.6.1
562        - another "make dist" fix, for the LV2 plugin
563        - made --enable-pthread-testcancel default on Mac OS X
564        - minor Makefile fix for building lscpparser when build and source
565          directories are separate
566        - Mac OS X: made it possible to specify plugin installation dir to
567          configure
568        - Mac OS X: Makefile fix for the install-strip target
569        - fixed compilation with gcc 4.7
570        - fixed configure script error with old autoconf versions

572          gcc 4.7 and C++11
573        - modernized configure script
574        - fixed linkage error when building with
575          LDFLAGS="-Wl,--no-undefined" (#190)
576        - fixed compilation with Clang 3.2

584          on the process's main thread
585        - fixed build error on newer MinGW
586        - support building with older jack versions
587        - support building with spaces in vst sdk path
588        - enabled automake 'subdir-objects' option and moved external
589          source references (vst, au, asio) from makefiles to cpp files,
590          in order to get rid of warnings from automake 1.14
591    
592      * general changes:
593        - Refactoring: moved the independent code from
594          the Gigasampler format engine to base classes
595        - command line option '--profile' is currently disabled, since the
596          respective profiling code is currently broken
597        - Introduced support for optional environment variable
598          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
599          where the sampler shall look for instrument editor plugins
600          (patch by Luis Garrido, slightly modified).
601        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
602        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
603        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
604          note (in this implementation of the sampler its simply hard routed to
605          the 1st effect send of the sampler channel, no matter what the actual
606          effect type is)
607        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
608          note (in this implementation of the sampler its simply hard routed to
609          the 2nd effect send of the sampler channel, no matter what the actual
610          effect type is)
611        - implemented support for internal LADSPA effects
612        - raised limit of program change queue from 100 to 512
613          (as suggested by Alex Stone)
614        - implemented sine LFO, pulse LFO and saw LFO
615        - experimental support for per voice equalization
616        - added command line option --exec-after-init
617        - Introduced new C++ API method:
618          EngineChannel::InstrumentFileName(int index)
619          allowing to retrieve the whole list of files used for the loaded
620          instrument on an engine channel (a.k.a. part). Some GigaStudio
621          instruments for example are splitted over several files like
622          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
623        - Added new C++ API method Sampler::GetGlobalMaxVoices().
624        - Added new C++ API method Sampler::GetGlobalMaxStreams().
625        - Added new C++ API method Sampler::SetGlobalMaxVoices().
626        - Added new C++ API method Sampler::SetGlobalMaxStreams().
627        - Various "const" and "restrict" optimizations.
628        - all engines: add pan CC value to instrument pan parameter before
629          applying panning, instead of using two separate pan functions in
630          series (#182)
631        - added a lock guard class for exception safe mutex handling and
632          used it everywhere appropriate
633        - Immediately apply scale tuning changes to active voices.
634        - Exposed scale tuning to C++ API (along to the already existing standard
635          SysEx way).
636        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
637          and broken for ppc64. (Seq_cst loads and stores are actually not
638          used in LS, so the bug wasn't noticable.)
639        - lsatomic.h: added ARMv7 support
640        - Added support for multiple MIDI input ports per sampler channel (and
641          added various new C++ methods for this new feature / design change, old
642          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
643          as deprecated but are still there and should provide full behavior
644          backward compatibility).
645        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
646          unsafe and caused compilation error with clang 2.x).
647        - Bugfix: only process the latest MIDI program change event.
648        - Introducing the LSCP shell, which provides convenient control of the
649          sampler from the command line by providing LSCP aware features.
650        - VirtualMidiDevice: Added support for program change.
651        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
652        - VirtualMidiDevice: Added support for pitch bend.
653        - Aftertouch: extended API to explicitly handle channel pressure and
654          polyphonic key pressure events (so far polyphonic pressure was not
655          supported at all, and channel pressure was rerouted as CC128 but not
656          used so far).
657        - Added initial support for real-time instrument scripts. The script VM
658          code is shared by all sampler engine implemementations, however only the
659          gig file format currently provides support for storing instrument scripts
660          (as LinuxSampler extension to the original GigaStudio 4 format).
661    
662      * Gigasampler format engine:
663        - implemented the "round robin keyboard" dimension
664        - fixed round robin and random dimensions for cases when number of
665          dimension zones is not a power of two
666        - made round robin use a counter for each region instead of each
667          key
668        - bugfix: pitch LFO controller "internal+aftertouch" was broken
669        - bugfix: filter keyboard tracking was broken
670        - filter performance fix (an unnecessary copy was made of the
671          filter parameters in each sub fragment)
672        - handle special case when pan parameter in gig file has max or
673          min value
674        - Exclusive Groups: don't ever stop voices of the same note,
675          doesn't sound naturally with a drumkit
676        - fixed EG1 modulation when attack or release is zero
677        - Fixed support for 'aftertouch' attenuation controller.
678        - Fixed crash that happened with velocity split sounds under certain
679          conditions (see also previous commit on libgig).
680        - fixed behaviour of filter LFO
681    
682      * SFZ format engine:
683        - Initial implementation (not usable yet)
684        - added support for v2 multiple stage envelope generators
685        - added a fine-tuned v1 envelope generator instead of using the
686          one from the gig engine
687        - fixed memory leak and memory handling errors
688        - added support for trigger=first, trigger=legato and sw_previous
689        - allow non-numerical key values ("C#4" for example)
690        - "key" opcode now sets pitch_keycenter too
691        - fixed error when unloading instrument with same sample used by
692          multiple regions
693        - added some opcode aliases, like loopmode for loop_mode, to be
694          more compatible
695        - added support for trigger=release and rt_decay
696        - added support for off_mode=normal
697        - added support for random, seq_position, seq_length and volume
698        - added v1 LFO opcodes to parser (no support in engine yet)
699        - added support for amp_veltrack and amp_velcurve_N
700        - fine-tuned the default velocity curve
701        - added support for transpose
702        - fixed crash when using sw_down/up
703        - improved logic for sw_lokey/hikey/up/down/last
704        - added more v1 aliases to parser
705        - reduced memory usage for sfz data
706        - RT-safeness: avoid malloc in audio thread
707        - fixed a bug that could cause voice stealing to fail
708        - optimized sample lookup
709        - improved support for exclusive groups (group, off_by and
710          off_mode)
711        - added support for controller triggered regions (on_locc/on_hicc)
712        - added support for loop_mode=one_shot
713        - fixed playback of 16 bit wav files on big endian CPUs
714        - added support for Ogg Vorbis sample files
715        - use loop markers from sample file if loop_start and loop_end are

919        - MME bugfix: driver wasn't closed properly
920        - CoreMIDI: automatically connect to all input sources by default (driver
921          parameter "AUTO_BIND").
922        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
923        - CoreMIDI: fixed minor memory leak
924    
925      * audio driver:

1040    
1041      * Bug fixes:
1042        - Fixed crash which may occur when MIDI key + transpose is out of range
1043        - minor valgrind fixes
1044        - fixed crash which occurred when changing an already deployed sampler
1045          channel to a different engine type
1046        - fixed crash when deleting a sampler channel or changing engine
1047          type while an instrument load was in progress
1048        - bugfix: playing a note while changing the instrument could cause
1049          a crash, or give "Handing back unknown region" error messages
1050        - bugfix: calling SET VOICES (which Fantasia does on start and
1051          refresh) could cause instruments to be unloaded
1052        - Mac OS X: fixed name collision of enum in EffectControl and
1053          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1054        - Mac OS X: fixed hanging threads
1055        - Windows: disabled the previous thread fix on non-Mac systems, as
1056          it caused hanging threads on Windows
1057        - Fixed possible crashes due to corrupted MIDI/audio device list
1058          after MIDI/audio device creation failure
1059        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1060          instruments were uselessly precached with zero samples, however it still
1061          took the full preloading time and on 1st program change the respective
1062          instrument was completely reloaded again.
1063        - fixed handling of rapid bank select and program change messages
1064          sent to the same sampler channel (patch from the Open Octave
1065          project, slightly adjusted)
1066        - fixed crash when trying to create an effect instance with controls
1067          which min and/or max values depend on the sample rate
1068        - fixed bug #162
1069        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1070          multiple paths (#165)
1071        - thread safety fixes for the instrument loading thread
1072        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1073          (#176)
1074        - more thread safety fixes for the instrument loading thread
1075        - sfz/sf2 engine: fixed crash when using small audio fragment size
1076        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1077        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1078          introduced in previous fix)
1079        - fixed crash when a channel received a program change while
1080          playing a note in a key group
1081        - fixed erroneous error message piping in VoiceBase.h
1082          (labelled "Disk stream not available in time")
1083        - Update effects on sample rate & period size changes (to avoid
1084          crashes and noise on such transitions).
1085        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1086          (fixes #208)
1087        - Fixed bug in LSCP grammar definition which caused a statement like
1088          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1089          practically irrelevant, however it caused problems with the new LSCP
1090          shell's auto completion feature).
1091        - Fixed MIDI program change messages being ignored if quickly executed
1092          after each other (fixes #231).
