1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13        - Added public API C++ class "LFO", which is a cluster class encapsulating
14          all the sampler's LFO implementations to be used by 3rd party applications
15          (e.g. by Gigedit).
16        - Added int math square LFO implementation.
17        - Added int math saw LFO implementation.
18        - Added numeric complex nr sine LFO implementation.
19        - Marked class LFOTriangleDiHarmonic as deprecated
20          (will be removed in future).
21        - Added LFOAll.h which includes all LFO implementation's header files.
22        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25          SquareLFO -> LFOSquarePulse and separated the latter to its own header
26          file).
27        - Renamed type LFOSigned -> LFOTriangleSigned.
28        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29        - Using now cubic interpolation as resampling algorithm by default; and
30          linear interpolation is deprecated now.
31        - Event:Init(): memset() entire Event::Param union to zero instead of trying
32          to do that for its individual members; the latter became error prone due
33          to the union's growing complexity meanwhile.
34        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36          methods and marked the old ones as deprecated; and likewise added new
37          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38          methods and marked those old ones deprecated as well.
39        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41    
42      * Real-time instrument scripts:
43        - Added method ScriptVM::setExitResultEnabled() which allows to
44          explicitly enable the built-in exit() function to optionally accept
45          one function argument; the value of the passed exit() function
46          argument will then become available by calling
47          VMExecContext::exitResult() after script execution.
48        - 64 bit support for NKSP integer scripts variables (declare $foo).
49        - Variable names, function names and preprocessor condition names must start
50          with a regular character (a-z or A-Z); starting them with a digit or
51          underscore is not allowed.
52        - NKSP parser fix: equal comparison operator "=" and not equal comparison
53          operator "#" must only accept integer operands.
54        - NKSP language: Implemented support for standard units like Hertz, seconds,
55          Bel including support for metric unit prefixes; so one can now e.g.
56          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
57          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
58          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
59        - NKSP language: Introduced "final" operator "!" which is specifically
60          intended for synthesis parameter values to denote that the synthesis
61          parameter value is intended to be the "final" value for that synthesis
62          parameter that should explicitly be used by the engine and thus causing
63          the sampler engine to ignore all other modulation sources for the same
64          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
65          variable or formula with this new "!" operator the expression is marked as
66          being "final".
67        - NKSP script editor API: Added support for detecting standard unit tokens
68          and their potential metric prefix token.
69        - NKSP language: Added support for NKSP real number literals and
70          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
71        - NKSP language: Added support for NKSP real number (floating point) script
72          variables (declare ~foo).
73        - NKSP language: Added support for NKSP real number (floating point) array
74          script variables (declare ?foo[]).
75        - Built-in script function "message()" accepts now real number argument as
76          well.
77        - Added built-in script function "real_to_int()" and its short hand form
78          "int()" for casting from real number to integer in NKSP scripts.
79        - Added built-in script function "int_to_real()" and its short hand form
80          "real()" for casting from integer to real number in NKSP scripts.
81        - Allow built-in exit() function to potentially accept real number type
82          argument as well.
83        - Built-in script functions may have a different return type depending on
84          the arguments passed to the function.
85        - Built-in script function "abs()" optionally accepts and returns real
86          number.
87        - Built-in script functions "min()" and "max()" optionally accept real
88          number arguments and return real number as result in that case.
89        - NKSP VM API: Allow units and 'final'ness to be returned as result from
90          built-in functions (added methods VMFunction::returnUnitType() and
91          VMFunction::returnsFinal() for that purpose which must be implemented by
92          built-in function implementations).
93        - NKSP language: Allow metric unit prefixes of numeric scalar and array
94          variables to be changed freely at runtime (unlike unit types like Hz etc.
95          which are still sticky, parse-time features of variables which cannot be
96          changed at runtime for the intentional sake of determinism).
97        - NKSP language: 'final' values are prohibited for array variables for now
98          (attempt causes a parsers error).
99        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
100          conditions of runtime control structures like if(), while(), select()
101          (attempt causes a parser error).
102        - NKSP VM API: Allow built-in functions to perform their own, individual
103          parse time checks of arguments going to be passed to the function at
104          runtime (added method VMFunction::checkArgs() for that purpose).
105        - NKSP language: raise parser warning if only one operand of binary
106          operators (like logical 'or' comparison) contain a 'final' value (because
107          it would always yield in a 'final' result in such cases).
108        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
109          different metric unit prefixes, which will behave as expected (e.g.
110          result of expression '1000us < 2ms' is true).
111        - NKSP language: Allow adding values with different metric unit prefixes
112          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
113        - NKSP language: Allow subtracting values with different metric unit
114          prefixes (e.g. result of expression '1ms - 20us' is '980us').
115        - NKSP language: Allow multiplying with any metric unit prefixes
116          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
117          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
118          we don't have any considerable practical use for a term like '4s^2'
119          (hence any attempt multiplying two unit types still causes parser error).
120        - NKSP language: Allow dividing by any metric unit prefixes and allow
121          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
122          yields in unit free result '8'). So this is now a way to cast units away
123          e.g. for passing the result to other expressions, certain function calls
124          or variables which are not accepting any units (or that specific unit).
125        - NKSP language: integer arrays and real number arrays can now be converted
126          to strings (e.g. for dumping their content with message() calls for
127          script debugging purposes).
128        - NKSP language: expressions and variables with units are now correctly
129          casted to strings (e.g. with message() calls).
130        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
131          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
132          floating point tolerances into account.
133        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
134          VMScalarNumberExpr::evalCastReal().
135        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
136          'VMIntArrayExpr' and 'VMRealArrayExpr'.
137        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
138          unitFactor() (runtime) methods.
139        - Built-in function "exit()" supports now returning units and 'final'ness
140          for test cases.
141        - The following built-in functions support now units as well: "abs()",
142          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
143          "real_to_int()", "int()", "int_to_real()" and "real()".
144        - Built-in functions "array_equal()", "search()" and "sort()" support now
145          real number arrays (correctly) as well.
146        - Added individual parse time checks of arguments to be passed to built-in
147          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
148          "array_equal()" and "search()" specific for their individual purposes.
149        - NKSP VM refactoring: Renamed all methods, functions and classes matching
150          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
151          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
152          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
153          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
154          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
155          isScalarNumber() -> isNumber()).
156        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
157          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
158          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
159          as convenient methods for automatically converting values to expected
160          metric value basis.
161        - Built-in function "wait()" accepts now both integers and real numbers as
162          argument.
163        - NKSP VM API cleanup: Get rid of legacy method
164          VMFunction::argType(vmint iArg) which was already superseded by its new
165          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
166        - NKSP parser: if wrong argument type was passed to a built-in function and
167          that built-in function accepts more than one data type for the argument,
168          then show all supported data types as parser error message.
169        - Built-in function "play_note()" accepts now real numbers and seconds as
170          unit type as well for its 3rd and 4th function arguments.
171        - The following built-in functions accept now real numbers as well for their
172          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
173          "change_attack()", "change_decay()", "change_release()",
174          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
175          "change_cutoff_sustain()", "change_cutoff_release()",
176          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
178          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
179        - Fixed built-in function "change_play_pos()" not having accepted metric
180          prefixes at all.
181        - Fixed the following built-in functions having misinterpreted values given
182          with unit type (for their 2nd argument) as if they were relative values
183          (that is as if they were passed without a unit type): "change_attack()",
184          "change_decay()", "change_release()", "change_cutoff_attack()",
185          "change_cutoff_decay()", "change_cutoff_release()".
186        - Fixed the following built-in functions having applied completely wrong
187          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
188          respective EGs being their modulation sink assume uint data type with
189          value range 0..1000 instead of 0.0..1.0.
190        - Added individual parse-time checks of function arguments for the following
191          built-in functions: "play_note()", "note_off()", "set_event_mark()",
192          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
193          "change_decay()", "change_release()", "change_cutoff_attack()",
194          "change_cutoff_decay()", "change_cutoff_release()",
195          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
196          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
197          "change_pan_time()".
198        - Don't abort function call if unit type was used and at the same time
199          'final' operator was omitted for the primary value argument of the
200          following built-in functions: "change_cutoff()", "change_attack()",
201          "change_decay()", "change_release()", "change_cutoff_attack()",
202          "change_cutoff_decay()", "change_cutoff_release()",
203          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
204          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
205          "change_pan_time()", instead imply 'final'ness at runtime and raise an
206          appropriate parser warning at parse time.
207        - Added built-in real number functions "round()", "ceil()", "floor()",
208          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
209          "cos()", "tan()", "asin()", "acos()", "atan()".
210        - Added built-in script real number constant "~NI_MATH_PI".
211        - Added built-in script real number constant "~NI_MATH_E".
212        - NKSP language: Allow unary '+' operator.
213        - Added built-in script functions "msb()" and "lsb()".
214    
215      * test cases:
216        - Fixed compiler errors in test cases.
217        - Updated README for how to compile & run test cases.
218        - Updated test case
219          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
220          expected behaviour of the Mutex class implementation (recursive
221          mutex type).
222        - Added test cases for NKSP core language aspects and core built-in
223          functions.
224        - Fixed thread tests segfaulting on Linux.
225        - NKSP: Added real number test cases for built-in functions exit(),
226          int_to_real(), real(), real_to_int() and int(), as well as for the
227          plus, minus and negate language operators.
228        - Added massive amount of NKSP test cases for standard measuring units and
229          'final' operator usage cases.
230        - Added NKSP test cases for (floating point tolerance aware) real number
231          equalness / unequalness comparison.
232        - Added NKSP int array and real array tests for value assignment and
233          initialization of arrays.
234        - Added NKSP test cases for built-in functions "round()", "ceil()",
235          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
236          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
237        - Added NKSP test cases for unary '+' operator.
238    
239      * GigaStudio/Gigasampler format engine:
240        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
241          behaviour for start_level_mid.
242        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
243          level (see discussion "GigaStudio LFO compatibility" on mailing list
244          from 2019-09-26 for details).
245        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
246          see discussion "GigaStudio LFO compatibility" on mailing list from
247          2019-09-26 for details).
248        - Format extension: Added support for different LFO wave forms (currently
249          either sine [default], triangle, saw or square).
250        - Format extension: Added support for LFO phase displacement (0°..360°).
251        - Format extension: Added support for flipping LFO polarity on LFO 3
252          (in the original gig format this was only available for LFO 1 and LFO 2).
253        - Format extension: Support for additional filter types:
254          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
255          bandreject 2-pole.
256    
257      * SFZ format engine:
258        - Fixed support for regions with loccN/hiccN conditions on more than one
259          MIDI controller.
260    
261      * Benchmarks:
262        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
263          algorithm (since result of 2nd run was not accumulated).
264        - Added benchmark for saw wave (benchmarks/saw.cpp).
265        - Added benchmark for sine wave (benchmarks/sine.cpp).
266        - Added benchmark for square wave (benchmarks/square.cpp).
267        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
268          which are large enough on modern systems.
269    
270    Version 2.1.1 (27 Jul 2019)
271    
272      * Real-time instrument scripts:
273        - Fixed behavior of built-in NKSP functions change_sustain(),
274          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
275          and change_cutoff_release().
276    
277      * general changes:
278        - Only play release trigger samples on sustain pedal up if this behaviour
279          was explicitly requested by the instrument (otherwise only on note-off).
280        - Fixed compiler warnings.
281        - Fixed compilation error when cross-compiling to Mac.
282        - FX Sends: Provide more useful error messages on routing problems
283          (see bug #169).
284        - LSCP doc: Be more clear describing the two distinct approaches
285          of using external vs. internal effects (see bug #169).
286        - "optional" class: Fixed comparison operators.
287    
288      * Gigasampler/GigaStudio format engine:
289        - Format extension: If requested by instrument then don't play release
290          trigger sample on note-off events.
291    
292      * SFZ format engine:
293        - Fixed memory leak when releasing samples
294          (fixes bug #307, patch by Jacek Roszkowski)
295        - Fixed potential crash when a sample is shared by more than one region
296          (fixes bug #308, patch by Jacek Roszkowski).
297        - Opcode 'sample': Added support for built-in sample '*silence'
298          (fixes bug #310, patch by Jacek Roszkowski).
299    
300    Version 2.1.0 (25 Nov 2017)
301    
302      * SFZ format engine:
303        - added support for <global>, <master> and #define (patch by Alby M)
304        - Removed code duplication in SFZ file loading code.
305        - Added support for sfz extension opcode 'script' which may be used to
306          load real-time instrument script file (NKSP script language).
307        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
308        - Fixed unintended volume fade-in of voices under certain conditions.
309        - sfz parser: allow missing space between header and opcode
310    
311      * Gigasampler/GigaStudio format engine:
312        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
313          cutoff settings.
314        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
315          all if an up-pitch of more than 40 semi tones was requested (I don't
316          think there is any stock gig sound that requires this behavior to
317          resemble its original sound).
318        - Added support for controlling whether the individual EGADSR stages may
319          be aborted (as LinuxSampler extension to the original GigaStudio 4
320          format).
321    
322      * general changes:
323        - fixed printf type errors (mostly in debug messages)
324        - use unique_ptr instead of auto_ptr when building with C++11
325        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
326          allowing to sort data efficiently in real-time safe manner.
327        - RTList class: added methods for moving/inserting elements to arbitrary
328          position within a list.
329        - RTList class: added method fromPtr() for creating an Iterator object from
330          a raw element pointer.
331        - Attempt to partly fix resetting engine channels vs. resetting engine, an
332          overall cleanup of the Reset*(), ConnectAudioDevice(),
333          DisconnectAudioDevice() API methods would still be desirable though,
334          because the current situation is still inconsistent and error prone.
335        - Active voices are now internally grouped to "Note" objects, instead of
336          being directly assigned to a keyboard key. This allows more fine graded
337          processing of voices, which is i.e. required for certain instrument
338          script features.
339        - Fix: Release trigger voices were not spawned on sustain pedal up
340          (CC #64) events.
341        - Fix: Release trigger voices can now also distinguish correctly between
342          note-off and sustain pedal up events.
343        - All engines: Increased ramp speed of volume smoother and pan smoother
344          (while slow rate of crossfade smoother is preserved) to allow quick
345          volume and pan changes by instrument scripts for instance.
346        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
347          properly and thus were ignored for certain uses.
348        - Added new C++ API method
349          VirtualMidiDevice::SendChannelPressureToSampler().
350        - windows, 32-bit: fixed potential crashes by making sure the stack in
351          sub threads is 16-byte aligned
352        - fixed numerous compiler warnings
353        - Fixed invalid (note-on) event ID being assigned to new Note objects.
354        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
355          fixes potential undefined behavior.
356        - Fixed Note object leak when triggering notes on keys which did not
357          have a valid sample mapped (fixes bug #252).
358        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
359        - linuxsampler binary fix: option --create-instruments-db ignored
360          subsequent optional argument due to glibc's implementation oddity
361          which expects a "=" sign, but no space between them.
362    
363      * packaging changes:
364        - removed unnecessary dependency to libuuid
365          (originated by libgig's usage of it)
366        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
367          auto detect whether it (sh/c)ould output its messages in color.
368        - Debian: Fixed packaging error about invalid "Source-Version"
369          substitution variable.
370        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
371        - Debian: Added build dependency to libsqlite3-dev for building
372          linuxsampler with instruments DB support.
373    
374      * Real-time instrument scripts:
375        - Implemented scheduler for delayed MIDI events and for suspended scripts.
376        - Built-in script function "wait()": implemented support for function's
377          "duration-us" argument, thus scripts using this function are now
378          correctly resumed after the requested amount of microseconds.
379        - Built-in script function "play_note()": implemented support for
380          function's "duration-us" argument, thus notes triggered with this
381          argument are now correctly released after the requested amount of
382          microseconds.
383        - Fix: script events were not cleared when engine channel was reset,
384          potentially causing undefined behavior.
385        - Fixed crash which happened when trying to reference an undeclared
386          variable.
387        - Built-in script function "play_note()": Added support for passing
388          special value -1 for "duration-us" argument, which will cause the
389          triggered note to be released once the original note was released.
390        - Instrument script classes now exported with the liblinuxsampler C++ API.
391        - Added new API method ScriptVM::syntaxHighlighting() which provides
392          a convenient syntax highlighting backend for external instrument
393          script editor applications.
394        - Added new C++ API class "ScriptVMFactory".
395        - Extended parser issues to provide not only first line and first
396          column, but also last line and last column of issue (thus marking
397          the precise span of the issue within the source code).
398        - Reload script automatically after being modified by an instrument
399          editor.
400        - NKSP language grammar correction: allow empty event handler bodies
401          like "on note end on".
402        - Implemented built-in script function "change_vol()".
403        - Implemented built-in script function "change_tune()".

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

437        - Added built-in script constant "$NI_CB_TYPE_NOTE".
438        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

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

469        - Implemented built-in script function "change_pitch_lfo_depth()".
470        - Implemented built-in script function "change_pitch_lfo_freq()".
471        - Implemented built-in script function "change_vol_time()".
472        - Implemented built-in script function "change_tune_time()".
473        - Implemented built-in script function "fade_in()".
474        - Implemented built-in script function "fade_out()".
475        - Fixed acceptance of wrong data type of parameters passed to built-in
476          script functions "change_vol()", "change_tune()", "change_pan()",
477          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
478          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
479          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
480        - Added built-in script function "get_event_par()" and implemented some
481          of its possible parameter selections.
482        - Added built-in script function "set_event_par()" and implemented some
483          of its possible parameter selections.
484        - Fixed a bunch of scheduler time related bugs.
485        - Fixed polyphonic variables not being reset to zero after usage.
486        - Built-in "ignore_event()" function: argument is now optional, like with
487          built-in function "ignore_controller()".
488        - Implemented built-in script function "change_velo()".
489        - Implemented built-in script function "change_note()".
490        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
491          intuitive behavior if used in combination with "change_vol_time()" or
492          "change_tune_time()" respectively: now tuning/volume changes are only
493          assigned (without delay) immediately to a new note if the respective
494          timing function has not been called before, otherwise the volume/tuning
495          changes are automatically faded (before, only the event's time stamp was
496          relevant).
497         - Implemented built-in script function "array_equal()".
498         - Implemented built-in script function "search()".
499         - Implemented built-in script function "sort()".
500         - NKSP Fix: Never suspend "init" event handlers.
501         - Implemented built-in script function "same_region()" (currently only
502           available for gig format engine).
503         - Added built-in script constant "$NKSP_LINEAR".
504         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
505         - Implemented built-in script function "change_vol_curve()".
506         - Implemented built-in script function "change_tune_curve()".
507         - built-in "play_note()" function now supports a sample playback start
508           offset with argument 3, where special value -1 means to use the regular
509           sample offset as defined by the instrument file.
510         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
511         - Built-in variable $EVENT_NOTE is now a read-only variable.
512         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
513         - built-in "play_note()" function now accepts -2 for its fourth argument
514           (note duration) which means the life time of the note shall be sticked
515           to the requested note number of argument 1.
516         - Fix: built-in "play_note()" function now returns 0 as result value if
517           -1 was passed for its fourth argument (note duration) and the respective
518           parent note is already gone.
519        - Implemented built-in script function "change_play_pos()".
520        - NKSP language: Added support for user declared const array variables.
521        - NKSP language: Raise parser warning if array variable is accessed with
522          an index that exceeds the array's size.
523        - NKSP language fix: Unknown characters were not handled correctly.
524        - NKSP language: Added support for "synchronized .. end synchronized"
525          code blocks.
526        - Implemented built-in script function "abort()" which allows to abort
527          another script handler by passing its callback ID.
528        - Fixed potential memory access bug and potential undefined behavior of
529          "init" event handlers.
530        - Print a time stamp along to each call of built-in function "message()".
531        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
532          to retrieve all code blocks filtered out by the preprocessor.
533        - Added built-in script function "fork()".
534        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
535        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
536        - Fixed potential crash when accessing dynamic built-in array variables.
537        - Added built-in script function "callback_status()".
538        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
539        - Added built-in constant $CALLBACK_STATUS_QUEUE.
540        - Added built-in constant $CALLBACK_STATUS_RUNNING.
541        - Removed max. value limitation of built-in functions "change_attack()",
542          "change_decay()" and "change_release()" to i.e. allow passing 2000000
543          for doubling the respective time.
544        - NKSP script editor syntax highlighting API: Fixed app termination due
545          to a lexer start condition stack underrun.
546        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
547          USE_CODE_IF_NOT() preprocessor statements.
548        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
549          can be set to disable all subsequent built-in "message()" function calls
550          on preprocessor level.
551        - Implemented built-in script function "change_sustain()".
552        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
553          to avoid the editor app to crash on ill-formed text input.
554        - Added built-in script function "change_pan_time()".
555        - Added built-in script function "change_pan_curve()".
556        - Added built-in script function "change_cutoff_attack()".
557        - Added built-in script function "change_cutoff_decay()".
558        - Added built-in script function "change_cutoff_sustain()".
559        - Added built-in script function "change_cutoff_release()".
560        - Added built-in script function "change_cutoff_lfo_depth()".
561        - Added built-in script function "change_cutoff_lfo_freq()".
562    
563      * Instruments DB:
564        - Fixed memory access bug of general DB access code which lead to
565          undefined behavior.
566        - Cleanup of instruments DB file creation and opening code.
567        - The instrument DB path of linuxsampler's --create-instruments-db argument
568          is now optional, if it is missing, then a default location is used.
569        - Added support for scanning SFZ (.sfz) files.
570        - Added support for scanning Sound Font (.sf2) files.
571        - Fixed undefined DB transaction behavior.
572    
573    Version 2.0.0 (15 July 2015)

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

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

1055        - Built-in script functions "ignore_event()", "note_off()" and
1056          "gig_set_dim_zone()" now also accept an array of event IDs as argument
1057          (i.e. return value of new script function "by_marks()").
1058        - Pass/preserve polyphonic variable data from respective "note" event
1059          handler to "release" event handler.
1060        - Fixed crash when using built-in script function "by_marks()".
1061

1063        - Fixed crash which may occur when MIDI key + transpose is out of range
1064        - minor valgrind fixes
1065        - fixed crash which occurred when changing an already deployed sampler
1066          channel to a different engine type
1067        - fixed crash when deleting a sampler channel or changing engine
1068          type while an instrument load was in progress
1069        - bugfix: playing a note while changing the instrument could cause
1070          a crash, or give "Handing back unknown region" error messages
1071        - bugfix: calling SET VOICES (which Fantasia does on start and
1072          refresh) could cause instruments to be unloaded
1073        - Mac OS X: fixed name collision of enum in EffectControl and
1074          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1075        - Mac OS X: fixed hanging threads
1076        - Windows: disabled the previous thread fix on non-Mac systems, as
1077          it caused hanging threads on Windows
1078        - Fixed possible crashes due to corrupted MIDI/audio device list
1079          after MIDI/audio device creation failure
1080        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1081          instruments were uselessly precached with zero samples, however it still
1082          took the full preloading time and on 1st program change the respective
1083          instrument was completely reloaded again.
1084        - fixed handling of rapid bank select and program change messages
1085          sent to the same sampler channel (patch from the Open Octave
1086          project, slightly adjusted)
1087        - fixed crash when trying to create an effect instance with controls
1088          which min and/or max values depend on the sample rate
1089        - fixed bug #162
1090        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1091          multiple paths (#165)
1092        - thread safety fixes for the instrument loading thread
1093        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1094          (#176)
1095        - more thread safety fixes for the instrument loading thread
1096        - sfz/sf2 engine: fixed crash when using small audio fragment size
1097        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1098        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1099          introduced in previous fix)
1100        - fixed crash when a channel received a program change while
1101          playing a note in a key group
1102        - fixed erroneous error message piping in VoiceBase.h
1103          (labelled "Disk stream not available in time")
1104        - Update effects on sample rate & period size changes (to avoid
1105          crashes and noise on such transitions).
1106        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1107          (fixes #208)
1108        - Fixed bug in LSCP grammar definition which caused a statement like
1109          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1110          practically irrelevant, however it caused problems with the new LSCP
1111          shell's auto completion feature).
1112        - Fixed MIDI program change messages being ignored if quickly executed
1113          after each other (fixes #231).
1114    
1115    Version 1.0.0 (31 July 2009)
1116    
1117      * packaging changes:
1118        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1119          causing e.g. the libgig test to fail when
1120          "./configure --disable-jack-driver" was used
1121          (patch by Alexis Ballier)
1122        - fixed compilation with gcc 4.3
1123        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1124        - fixed configure so it detects x86_64 (#107)
1125        - fixes for building with newer MinGW versions
1126        - fix for building with bison 2.4 (#111)
1127        - fixed building with libgig installed in a non-standard directory
1128        - minor fix in configure for mmsystem.h detection on MinGW
1129        - Windows: look for editor plugins and Fantasia using base
1130          directory of liblinuxsampler dll (look in the same directory and one
1131          directory above)
1132        - configure script fix: removed unconditional use of SSE
1133        - fixed building with sqlite installed in a non-standard directory
1134        - when cross-compiling, don't try to create instruments.db
1135        - fix for new mingw-w64 version, which has usleep
1136    
1137      * general changes:
1138        - bugfix: on some POSIX systems instrument editor plugins refused to
1139          load as we used a non-portable Linux specific struct field
1140          (fixes bug #70, patch by Ronald Baljeu)
1141        - fixed endless loop which occured when loading an instrument editor
1142          plugin DLL on Windows systems failed
1143        - fixed memory leaks that occurred when liblinuxsampler was unloaded
1144        - optimized the SynchronizedConfig class so it doesn't wait
1145          unnecessarily long after an update
1146        - added support for notifying instrument editors on note-on / note-off
1147          events (e.g. to highlight the pressed keys on the virtual keyboard
1148          of gigedit)
1149        - added support for triggering notes by instrument editors (see above)
1150        - be verbose on DLL load errors (on Linux)
1151        - fixed di-harmonic triangle LFO implementation (this LFO implementation
1152          is only used by very few systems, most pick the int math
1153          implementation, which is usually faster)
1154        - fixes for audio drivers with varying buffer sizes
1155        - experimental support for running LinuxSampler as a DSSI, LV2 and
1156          VST plugin
1157        - notification events for stream/voice count statistics are now sent
1158          only when there are actual changes
1159        - added memory ordering constraints to improve stability on
1160          multi-core and multi-cpu systems
1161        - maximum voices and disk streams can now be altered at runtime
1162        - fixed CPU feature detection on x86_64 (maybe fixes #108)
1163        - automatic stacktrace mechanism is now turned off by default and can
1164          be switched on by command line option "--stacktrace" (the automatic
1165          stacktrace mechanism seems to be broken on most systems at the moment)
1166        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1167          a pointer to the launched InstrumentEditor object
1168        - added optional 3rd party user data parameter for following
1169          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1170          InstrumentEditor::Launch(),
1171          InstrumentManager::LaunchInstrumentEditor()
1172        - theoretical fix: made SynchronizedConfig follow C++0x memory
1173          model more strictly
1174        - fixes for using large audio device buffers
1175        - Windows: add the installation directory to the DLL search path
1176          when loading an editor plugin (solves problems with VST and
1177          gigedit on systems with other GTK versions installed)
1178        - updated linuxsampler man page
1179    
1180      * audio driver:
1181        - removed the nonsense audio channel constraint (which was hard coded to
1182          max. 100 audio channels) for most audio drivers
1183        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1184          opposed to the LSCP specs
1185        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1186          reflected the wrong value
1187        - fixed a memory management bug in ASIO driver
1188        - Makefile fix: JACK_CFLAGS wasn't used
1189        - JACK: use jack_client_open instead of the deprecated
1190          jack_client_new
1191        - added (experimental) CoreAudio driver
1192        - applied old fixes to the ASIO driver that were included in the
1193          previous binary release but accidentally never committed to CVS
1194          (fixes #117)
1195        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1196          win64)
1197        - VST: added support for sample rate and buffer size changes
1198        - VST: close editor (Fantasia) when the VST is removed
1199        - VST: avoid opening Fantasia more than once for each VST instance
1200        - VST: export main function as "main" on Linux too (fix for
1201          energyXT)
1202        - VST: changed number of output channels from one stereo to 16
1203          stereo
1204        - added channel routing, fxsends and midi maps to the settings
1205          stored in the plugin state
1206        - performance optimization of AudioChannel::MixTo() and
1207          AudioChannel::CopyTo() methods using GCC vector exensions
1208          (if available)
1209        - ASIO fixes: avoid initializing the device twice, avoid throwing
1210          exception when getting parameters from a disconnected device
1211    
1212      * MIDI driver:
1213        - added JACK MIDI driver
1214        - dispatch bank select as ordinary CC as well, the user might seriously
1215          want to (mis)use it for some purpose ("fixed" in all current MIDI
1216          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1217        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1218          CoreMidi or AU
1219        - fixed mingw-w64 compilation error in MME driver
1220        - made program change handling in MIDI thread real-time safe by
1221          moving the logic to a non-RT thread
1222        - fixed minor memory leak in ALSA driver
1223    
1224      * instruments database:
1225        - avoid time consuming samples scanning when adding instruments
1226          to the instruments database
1227        - added support for handling lost files in the instruments database
1228        - Implemented option for adding instruments in separate directories
1229          in the instruments database
1230          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1231        - work-around for missing fnmatch function on Windows to make
1232          instrument database compilable
1233        - added instrument database support on Windows
1234          works with both standalone mode and VST plugin.
1235          the instruments DB file is located in
1236          %USERPROFILE%\.linuxsampler\instruments.db which allows different
1237          databases for each windows user
1238          if no DB is present it automatically creates the .linuxsampler subdir
1239          and then creates an empty DB
1240        - fixed recursive import, which was broken on Windows
1241    
1242      * Gigasampler format engine:
1243        - fixed a memory leak that could happen when a channel was deleted
1244          while notes were playing
1245        - made it possible to load an instrument even if the audio thread
1246          isn't running
1247        - added partial support for the "Controller Triggered" MIDI rule,
1248          enough for piano gigs with pedal noise samples
1249        - minor fix: only mark FX sends as being modified if really the
1250          respective FX send MIDI controller was used
1251        - added support for GM global device volume SysEx message
1252          (can be selected at compile time to either apply globally to the
1253          whole sampler [default] or only to the sampler channels that are
1254          connected to the respective MIDI input port the SysEx message arrived
1255          on)
1256        - bugfix: notes triggered at position 0 in the audio buffer were
1257          sometimes wrongly killed in the same buffer, causing no sound to
1258          be played
1259        - added support for chromatic / drumkit mode Roland GS Sysex message
1260          which is usally used to switch a part between chromatic sounds and
1261          drumkit sounds (as opposed to their common default setting of MIDI
1262          part 10 being a drumkit part and all other ones chromatic parts), in
1263          LS however one can switch between the first 16 MIDI instrument maps
1264          defined for the sampler
1265        - made it possible to create multiple sample channels even if the
1266          audio thread isn't running
1267        - fixed crash when removing channel with active voices (#116)
1268        - bugfix: on sample reference changes (instrument editor), only
1269          un-cache the respective sample if it's really not used by any
1270          sampler engine anymore
1271        - re-cache samples in case they were changed by an instrument editor,
1272          e.g. when a sample was added while playing (#82)
1273        - fixed hanging notes which occured when note-off event had the exact
1274          same time stamp as the voice's note-on event and occured both in the
1275          same audio fragment cycle (fixes bug #112)
1276        - added support for the "fine tune" and "pitch bend range"
1277          instrument-level gig parameters
1278        - fixed minor artifacts in pitch bend handling
1279        - added support for GS Reset SysEx message
1280        - allow gig files to use unlimited downward pitch shifting
1281        - added a limit check for upward pitch shifting
1282        - bugfix: sometimes, when playing a note twice fast, the second
1283          note was silent
1284        - fixed crash happening when a pitch bend event arrived at the
1285          same time a new instrument was loading
1286    
1287      * LSCP server:
1288        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1289          react on MIDI data arriving on certain sampler channels (so far only
1290          Note-On and Note-Off events are sent via this LSCP event)
1291        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1292          react on MIDI data arriving on certain MIDI input devices (so far only
1293          Note-On and Note-Off events are sent via this LSCP event)
1294        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1295          SET DB_INSTRUMENT FILE_PATH
1296        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1297          frontends to send MIDI messages to specific sampler channel
1298        - added two additional fields to GET FILE INSTRUMENT INFO command -
1299          KEY_BINDINGS and KEYSWITCH_BINDINGS
1300        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1301          was incorrect
1302        - Optimized the retrieval of the MIDI instrument mappings
1303        - added new LSCP command "SET VOICES" to globally alter the maximum
1304          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1305          be triggered respectively
1306        - added new LSCP command "SET STREAMS" to globally alter the maximum
1307          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1308          which will be triggered respectively
1309        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1310          a gigedit file dialog is opened)
1311        - close all connections when LSCPServer is deleted
1312        - hard close of all sockets on exit
1313        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1314          driver
1315    
1316      * Bug fixes:
1317        - fixed a crash which occurs when removing a sampler channel waiting
1318          to start instrument loading after another channel
1319        - fixed a crash which occurs when removing a sampler channel with
1320          instrument loading in progress (bug #113)
1321        - fixed termination caused by uncaught exception when adding MIDI
1322          instrument with PERSISTENT load mode
1323        - fixed possible iterator invalidations when resetting the sampler
1324        - fixed memory leaks when issuing the following LSCP commands:
1325          GET AUDIO_OUTPUT_DRIVER INFO
1326          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1327          GET MIDI_INPUT_DRIVER INFO
1328          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1329        - fixed possible compilation error when sqlite is not present
1330        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1331        - fixed crash when changing the audio output device of a sampler
1332          channel with loaded instrument and start playing notes
1333        - fixed endless loop in Engine::SuspendAll() (bug #120)
1334        - fixed a low-level atomic load function that was broken on 64-bit
1335          PowerPC, which probably could cause crashes on that platform
1336        - fixed a memory management error which could cause a crash when a
1337          plugin was unloaded
1338        - bugfix: two private structs had the same name, which could cause
1339          problems if the linker chose the wrong constructor
1340        - fixed low-level ConditionServer usage bug that caused lockups on
1341          Windows
1342    
1343    
1344    Version 0.5.1 (6 December 2007)
1345    
1346      * packaging changes:
1347        - added autoconf checks for pthread library
1348        - added autoconf check for pthread bug found on certain NPTL-enabled
1349          glibc versions (see Gentoo bug report #194076)
1350        - added autoconf checks for MS Windows
1351    
1352      * general changes:
1353        - bugfix: the thread used by an editor plugin didn't die when the
1354          editor closed
1355        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1356          out all the space. operator--() did not apply size_mask after
1357          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1358          order to avoid problems with the _NonVolatileReader functions.
1359        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1360          GetWriteSpace(). Since this function is currently only used in
1361          the stream's qsort() compare function, it didn't trigger any
1362          bugs.
1363        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1364          24bit mode too. Faster method to read 24bit words on little
1365          endian machines (x86): replaced 3 byte reads + shifts with a 1
1366          unaligned 32bit read and shift
1367        - experimental support for MS Windows (MIDI input via MME, AUDIO
1368          output via ASIO)
1369        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1370        - support for monitoring the total number of active disk streams
1371          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1372          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1373    
1374      * AUDIO driver:
1375        - added Windows ASIO low latency audio driver
1376    
1377      * MIDI driver:
1378        - added MME Windows MIDI driver
1379    
1380      * LSCP server:
1381        - added support for Windows style path / filenames, however with
1382          forward slash path separators instead of backslash
1383          (i.e. "C:/foo/bar.gig")
1384        - allow naughty liblscp to send non-string device parameters within
1385          apostrophes as well
1386        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1387          "LIST FILE INSTRUMENTS <file>" and
1388          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1389          about an arbitrary instrument file on the system where the sampler is
1390          running on
1391    
1392    Version 0.5.0 (15 October 2007)
1393    
1394      * packaging changes:
1395        - config.h is not going to be installed along with liblinuxsampler's
1396          API header files anymore
1397        - only the API relevant header (and source) files will be exported to
1398          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1399        - added completely new XCode project files for Mac OSX which is now
1400          capable to execute our autoconf environment, thus no need anymore
1401          to maintain the compile time configuration file (osx/version.h) for
1402          OSX manually (patch by Toshi Nagata)
1403        - fixed buggy boolean --enable-foo / --disable-foo configure script
1404          parameters
1405        - global.h now only covers global definitions that are needed for the
1406          C++ API header files, all implementation internal global definitions
1407          are now in global_private.h
1408        - atomic.h is not exposed to the C++ API anymore
1409        - no need to include config.h anymore for using LS's API header files
1410        - fixed warnings in API doc generation

1439        - Implemented new, improved notification system
1440        - fixed compilation errors regarding OSX
1441          (patch by Toshi Nagata)
1442        - implemented instruments database
1443        - added support for escape sequences to the instruments database
1444        - added highly experimental support for on-the-fly instrument editing
1445          within the sampler's process (by using instrument editor plugins),
1446          you'll notice the new "Registered instrument editors:" message on
1447          startup, added a new LSCP command:
1448          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1449          to spawn a matching instrument editor for the instrument on the
1450          given sampler channel, the plugin path can be overridden at compile
1451          time with ./configure --enable-plugin-dir=/some/dir
1452        - added experimental code for synchronizing instrument editors hosted
1453          in the sampler's process to safely edit instruments while playing
1454          without a crash (hopefully) by either suspending single regions
1455          wherever possible or if unavoidable whole engine(s)
1456        - fixed several issues in fundamental "Thread" class: set scheduling
1457          policy and priority on thread level, set a minimum stack size for
1458          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1459          threads simply inherited properties of starting thread instead of
1460          setting their own policy and priority
1461        - minor fix in our automatic stack trace mechanism on crashes, the
1462          main process did not wait for the stack trace process to finish
1463          its output
1464        - fixed some minor memory leaks
1465        - reenabled assembly features support, at the moment only for
1466          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1467        - minor assembly fix in x86 features detection (don't use the PIC
1468          register, to avoid relocations in the text segment at runtime)
1469        - POSIX callback functions of Thread.h are hidden

1489        - EG fine tuning: when attack is zero the EG starts at a level
1490          above max sustain level, which means that there is a decay phase
1491          even if sustain is 100%
1492        - more EG fixes: the level could sometimes go below zero and cause
1493          noises or crashes
1494        - minor fix of EGDecay (patch by Toshi Nagata)
1495        - fixed compiler error when --enable-override-filter-type was
1496          supplied to the configure script (fixes #46)
1497        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1498          instead of a fix value
1499        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1500          127 (solo mode) only kill voices if the respective mode really
1501          changed
1502    
1503      * LSCP server:
1504        - fixed compile time error for old Bison versions
1505          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1506        - parser now supports extended ASCII character set
1507          (up to ASCII code 255, i.e. includes now umlauts and accents)
1508        - filename arguments in LSCP commands now allow to use escape
1509          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1510          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1511          code value like \xf2) (fixes bug #24)
1512        - the following LSCP commands now also support escape sequences for at
1513          least one of their text-based parameters (i.e. name, description):
1514          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1515          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1516          "SET DB_INSTRUMENT_DIRECTORY NAME",
1517          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1518          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1519          "FIND DB_INSTRUMENT_DIRECTORIES"
1520        - returns verbose syntax errors (line and column where syntax error
1521          occured, the unexpected character and the actually expected, possible
1522          character(s), the latter only if less than 5 possibilities)
1523        - made sure that LSCP syntax is not affected by gigedit locale
1524          settings
1525        - bugfix regarding strings parameter lists: all comma separated lists
1526          of strings were treated as being one string containing commas
1527          (fixes #57)
1528

1532        channel audio output device"        channel audio output device"
1533        - fixed a crash which occurs when reassigning the same engine
1534          on a sampler channel with connected MIDI device
1535        - fixed a crash which occurs when changing the number of ports of a MIDI
1536          device connected to a sampler channel to number less then or equal
1537          to the index of the port to which the sampler channel is connected.
1538        - The previous bindings were not been disconnected when altering
1539          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1540          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1541        - The active stream/voice count statistic was incorrect.
1542        - notification events were not been sent for some sampler
1543          channel changes
1544        - added default min and max values to restrict the number of allowed
1545          audio output channels and MIDI input ports
1546        - the connection to the PCM interface is now closed when destroying
1547          an audio output device
1548        - files with slash in their path or filename could not be loaded
1549
