# 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    
230      * SFZ format engine:
231        - Fixed support for regions with loccN/hiccN conditions on more than one
232          MIDI controller.
233    
234      * Benchmarks:
235        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
236          algorithm (since result of 2nd run was not accumulated).
237        - Added benchmark for saw wave (benchmarks/saw.cpp).
238        - Added benchmark for sine wave (benchmarks/sine.cpp).
239        - Added benchmark for square wave (benchmarks/square.cpp).
240        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
241          which are large enough on modern systems.
242    
243    Version 2.1.1 (27 Jul 2019)
244    
245      * Real-time instrument scripts:
246        - Fixed behavior of built-in NKSP functions change_sustain(),
247          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
248          and change_cutoff_release().
249    
250      * general changes:
251        - Only play release trigger samples on sustain pedal up if this behaviour
252          was explicitly requested by the instrument (otherwise only on note-off).
253        - Fixed compiler warnings.
254        - Fixed compilation error when cross-compiling to Mac.
255        - FX Sends: Provide more useful error messages on routing problems
256          (see bug #169).
257        - LSCP doc: Be more clear describing the two distinct approaches
258          of using external vs. internal effects (see bug #169).
259        - "optional" class: Fixed comparison operators.
260    
261      * Gigasampler/GigaStudio format engine:
262        - Format extension: If requested by instrument then don't play release
263          trigger sample on note-off events.
264    
265      * SFZ format engine:
266        - Fixed memory leak when releasing samples
267          (fixes bug #307, patch by Jacek Roszkowski)
268        - Fixed potential crash when a sample is shared by more than one region
269          (fixes bug #308, patch by Jacek Roszkowski).
270        - Opcode 'sample': Added support for built-in sample '*silence'
271          (fixes bug #310, patch by Jacek Roszkowski).
272    
273    Version 2.1.0 (25 Nov 2017)
274    
275      * SFZ format engine:
276        - added support for <global>, <master> and #define (patch by Alby M)
277        - Removed code duplication in SFZ file loading code.
278        - Added support for sfz extension opcode 'script' which may be used to
279          load real-time instrument script file (NKSP script language).
280        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
281        - Fixed unintended volume fade-in of voices under certain conditions.
282        - sfz parser: allow missing space between header and opcode
283    
284      * Gigasampler/GigaStudio format engine:
285        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
286          cutoff settings.
287        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
288          all if an up-pitch of more than 40 semi tones was requested (I don't
289          think there is any stock gig sound that requires this behavior to
290          resemble its original sound).
291        - Added support for controlling whether the individual EGADSR stages may
292          be aborted (as LinuxSampler extension to the original GigaStudio 4
293          format).
294    
295      * general changes:
296        - fixed printf type errors (mostly in debug messages)
297        - use unique_ptr instead of auto_ptr when building with C++11
298        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
299          allowing to sort data efficiently in real-time safe manner.
300        - RTList class: added methods for moving/inserting elements to arbitrary
301          position within a list.
302        - RTList class: added method fromPtr() for creating an Iterator object from
303          a raw element pointer.
304        - Attempt to partly fix resetting engine channels vs. resetting engine, an
305          overall cleanup of the Reset*(), ConnectAudioDevice(),
306          DisconnectAudioDevice() API methods would still be desirable though,
307          because the current situation is still inconsistent and error prone.
308        - Active voices are now internally grouped to "Note" objects, instead of
309          being directly assigned to a keyboard key. This allows more fine graded
310          processing of voices, which is i.e. required for certain instrument
311          script features.
312        - Fix: Release trigger voices were not spawned on sustain pedal up
313          (CC #64) events.
314        - Fix: Release trigger voices can now also distinguish correctly between
315          note-off and sustain pedal up events.
316        - All engines: Increased ramp speed of volume smoother and pan smoother
317          (while slow rate of crossfade smoother is preserved) to allow quick
318          volume and pan changes by instrument scripts for instance.
319        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
320          properly and thus were ignored for certain uses.
321        - Added new C++ API method
322          VirtualMidiDevice::SendChannelPressureToSampler().
323        - windows, 32-bit: fixed potential crashes by making sure the stack in
324          sub threads is 16-byte aligned
325        - fixed numerous compiler warnings
326        - Fixed invalid (note-on) event ID being assigned to new Note objects.
327        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
328          fixes potential undefined behavior.
329        - Fixed Note object leak when triggering notes on keys which did not
330          have a valid sample mapped (fixes bug #252).
331        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
332        - linuxsampler binary fix: option --create-instruments-db ignored
333          subsequent optional argument due to glibc's implementation oddity
334          which expects a "=" sign, but no space between them.
335    
336      * packaging changes:
337        - removed unnecessary dependency to libuuid
338          (originated by libgig's usage of it)
339        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
340          auto detect whether it (sh/c)ould output its messages in color.
341        - Debian: Fixed packaging error about invalid "Source-Version"
342          substitution variable.
343        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
344        - Debian: Added build dependency to libsqlite3-dev for building
345          linuxsampler with instruments DB support.
346    
347      * Real-time instrument scripts:
348        - Implemented scheduler for delayed MIDI events and for suspended scripts.
349        - Built-in script function "wait()": implemented support for function's
350          "duration-us" argument, thus scripts using this function are now
351          correctly resumed after the requested amount of microseconds.
352        - Built-in script function "play_note()": implemented support for
353          function's "duration-us" argument, thus notes triggered with this
354          argument are now correctly released after the requested amount of
355          microseconds.
356        - Fix: script events were not cleared when engine channel was reset,
357          potentially causing undefined behavior.
358        - Fixed crash which happened when trying to reference an undeclared
359          variable.
360        - Built-in script function "play_note()": Added support for passing
361          special value -1 for "duration-us" argument, which will cause the
362          triggered note to be released once the original note was released.
363        - Instrument script classes now exported with the liblinuxsampler C++ API.
364        - Added new API method ScriptVM::syntaxHighlighting() which provides
365          a convenient syntax highlighting backend for external instrument
366          script editor applications.
367        - Added new C++ API class "ScriptVMFactory".
368        - Extended parser issues to provide not only first line and first
369          column, but also last line and last column of issue (thus marking
370          the precise span of the issue within the source code).
371        - Reload script automatically after being modified by an instrument
372          editor.
373        - NKSP language grammar correction: allow empty event handler bodies
374          like "on note end on".

381        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
382          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
383          "event_status()" function.
384        - NKSP language: Added support for bitwise operators ".or.", ".and."
385          and ".not.".
386        - NKSP language scanner: Fixed IDs matching to require at least one
387          character (i.e. when matching function names or variable names).
388        - NKSP language scanner: disabled unusued rules.
389        - Fixed behavior of play_note() and note_off() functions which must
390          be distinguished engine internally from "real" MIDI note on/off
391          events in order to avoid misbehaviors like hanging notes.
392        - Implemented built-in script variable "$KSP_TIMER".
393        - Implemented built-in script variable "$NKSP_REAL_TIMER".
394        - Implemented built-in script variable "$NKSP_PERF_TIMER".

397        - Implemented built-in script function "dec()".
398        - NKSP language fix: division expressions were evaluated too often.
399        - NKSP language fix: string concatenation operator was right
400          associative instead of left (to right).
401        - NKSP language correction: allow empty statements in entire language
402          (i.e. "if end if").
403        - Implemented built-in script function "stop_wait()".
404        - Implemented built-in script variable "$NI_CALLBACK_ID".
405        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
406        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

417        - Fixed all change_*() built-in script functions to apply their
418          synthesis parameter changes immediately in case the respective note
419          was triggered at the same time, instead of scheduling the parameter
420          change, especially because it would cause some parameter types's
421          changes either to be ramped (i.e. change_vol()) or other types even
422          to have not effect at all (i.e. change_attack()).
423        - Implemented built-in script function "sh_left()".

427        - NKSP Fix: "init" event handler was not always executed when a script
428          was loaded.
429        - NKSP built-in wait() script function: abort script execution if
430          a negative or zero wait time was passed as argument (since this is
431          a common indication of a bug either of the script or even of the
432          engine, which could lead to RT instability or even worse).
433        - ScriptVM: Implemented automatic suspension of RT safety
434          threatening scripts.
435        - Provide more user friendly error messages on syntax errors.
436        - Fixed NKSP parser warning "Not a statement" when assigning an

448        - Fixed acceptance of wrong data type of parameters passed to built-in
449          script functions "change_vol()", "change_tune()", "change_pan()",
450          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
451          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
452          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
453        - Added built-in script function "get_event_par()" and implemented some
454          of its possible parameter selections.
455        - Added built-in script function "set_event_par()" and implemented some
456          of its possible parameter selections.
457        - Fixed a bunch of scheduler time related bugs.
458        - Fixed polyphonic variables not being reset to zero after usage.
459        - Built-in "ignore_event()" function: argument is now optional, like with
460          built-in function "ignore_controller()".
461        - Implemented built-in script function "change_velo()".
462        - Implemented built-in script function "change_note()".
463        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
464          intuitive behavior if used in combination with "change_vol_time()" or
465          "change_tune_time()" respectively: now tuning/volume changes are only
466          assigned (without delay) immediately to a new note if the respective
467          timing function has not been called before, otherwise the volume/tuning
468          changes are automatically faded (before, only the event's time stamp was
469          relevant).
470         - Implemented built-in script function "array_equal()".
471         - Implemented built-in script function "search()".
472         - Implemented built-in script function "sort()".
473         - NKSP Fix: Never suspend "init" event handlers.
474         - Implemented built-in script function "same_region()" (currently only
475           available for gig format engine).
476         - Added built-in script constant "$NKSP_LINEAR".
477         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
478         - Implemented built-in script function "change_vol_curve()".
479         - Implemented built-in script function "change_tune_curve()".
480         - built-in "play_note()" function now supports a sample playback start
481           offset with argument 3, where special value -1 means to use the regular
482           sample offset as defined by the instrument file.
483         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
484         - Built-in variable $EVENT_NOTE is now a read-only variable.
485         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
486         - built-in "play_note()" function now accepts -2 for its fourth argument
487           (note duration) which means the life time of the note shall be sticked
488           to the requested note number of argument 1.
489         - Fix: built-in "play_note()" function now returns 0 as result value if
490           -1 was passed for its fourth argument (note duration) and the respective
491           parent note is already gone.
492        - Implemented built-in script function "change_play_pos()".
493        - NKSP language: Added support for user declared const array variables.
494        - NKSP language: Raise parser warning if array variable is accessed with
495          an index that exceeds the array's size.

497        - NKSP language: Added support for "synchronized .. end synchronized"
498          code blocks.

501        - Fixed potential memory access bug and potential undefined behavior of
502          "init" event handlers.
503        - Print a time stamp along to each call of built-in function "message()".
504        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
505          to retrieve all code blocks filtered out by the preprocessor.
506        - Added built-in script function "fork()".
507        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
508        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
509        - Fixed potential crash when accessing dynamic built-in array variables.
510        - Added built-in script function "callback_status()".
511        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
512        - Added built-in constant $CALLBACK_STATUS_QUEUE.
513        - Added built-in constant $CALLBACK_STATUS_RUNNING.
514        - Removed max. value limitation of built-in functions "change_attack()",
515          "change_decay()" and "change_release()" to i.e. allow passing 2000000
516          for doubling the respective time.
517        - NKSP script editor syntax highlighting API: Fixed app termination due
518          to a lexer start condition stack underrun.
519        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
520          USE_CODE_IF_NOT() preprocessor statements.
521        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
522          can be set to disable all subsequent built-in "message()" function calls
523          on preprocessor level.
524        - Implemented built-in script function "change_sustain()".
525        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
526          to avoid the editor app to crash on ill-formed text input.
527        - Added built-in script function "change_pan_time()".
528        - Added built-in script function "change_pan_curve()".

530        - Added built-in script function "change_cutoff_decay()".
531        - Added built-in script function "change_cutoff_sustain()".
532        - Added built-in script function "change_cutoff_release()".
533        - Added built-in script function "change_cutoff_lfo_depth()".
534        - Added built-in script function "change_cutoff_lfo_freq()".
535    
536      * Instruments DB:

538          undefined behavior.
539        - Cleanup of instruments DB file creation and opening code.
540        - The instrument DB path of linuxsampler's --create-instruments-db argument
541          is now optional, if it is missing, then a default location is used.
542        - Added support for scanning SFZ (.sfz) files.
543        - Added support for scanning Sound Font (.sf2) files.
544        - Fixed undefined DB transaction behavior.

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

567        - modernized configure script
568        - fixed linkage error when building with
569          LDFLAGS="-Wl,--no-undefined" (#190)

579        - fixed build error on newer MinGW
580        - support building with older jack versions
581        - support building with spaces in vst sdk path
582        - enabled automake 'subdir-objects' option and moved external
583          source references (vst, au, asio) from makefiles to cpp files,
584          in order to get rid of warnings from automake 1.14
585    
586      * general changes:
587        - Refactoring: moved the independent code from
588          the Gigasampler format engine to base classes
589        - command line option '--profile' is currently disabled, since the
590          respective profiling code is currently broken
591        - Introduced support for optional environment variable
592          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
593          where the sampler shall look for instrument editor plugins
594          (patch by Luis Garrido, slightly modified).
595        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
596        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
597        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
598          note (in this implementation of the sampler its simply hard routed to
599          the 1st effect send of the sampler channel, no matter what the actual
600          effect type is)
601        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
602          note (in this implementation of the sampler its simply hard routed to
603          the 2nd effect send of the sampler channel, no matter what the actual
604          effect type is)
605        - implemented support for internal LADSPA effects
606        - raised limit of program change queue from 100 to 512
607          (as suggested by Alex Stone)
608        - implemented sine LFO, pulse LFO and saw LFO
609        - experimental support for per voice equalization
610        - added command line option --exec-after-init
611        - Introduced new C++ API method:
612          EngineChannel::InstrumentFileName(int index)
613          allowing to retrieve the whole list of files used for the loaded
614          instrument on an engine channel (a.k.a. part). Some GigaStudio
615          instruments for example are splitted over several files like
616          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
617        - Added new C++ API method Sampler::GetGlobalMaxVoices().
618        - Added new C++ API method Sampler::GetGlobalMaxStreams().
619        - Added new C++ API method Sampler::SetGlobalMaxVoices().
620        - Added new C++ API method Sampler::SetGlobalMaxStreams().
621        - Various "const" and "restrict" optimizations.
622        - all engines: add pan CC value to instrument pan parameter before
623          applying panning, instead of using two separate pan functions in
624          series (#182)
625        - added a lock guard class for exception safe mutex handling and
626          used it everywhere appropriate
627        - Immediately apply scale tuning changes to active voices.
628        - Exposed scale tuning to C++ API (along to the already existing standard
629          SysEx way).
630        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
631          and broken for ppc64. (Seq_cst loads and stores are actually not
632          used in LS, so the bug wasn't noticable.)
633        - lsatomic.h: added ARMv7 support
634        - Added support for multiple MIDI input ports per sampler channel (and
635          added various new C++ methods for this new feature / design change, old
636          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
637          as deprecated but are still there and should provide full behavior
638          backward compatibility).
639        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
640          unsafe and caused compilation error with clang 2.x).
641        - Bugfix: only process the latest MIDI program change event.
642        - Introducing the LSCP shell, which provides convenient control of the
643          sampler from the command line by providing LSCP aware features.
644        - VirtualMidiDevice: Added support for program change.
645        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
646        - VirtualMidiDevice: Added support for pitch bend.
647        - Aftertouch: extended API to explicitly handle channel pressure and
648          polyphonic key pressure events (so far polyphonic pressure was not
649          supported at all, and channel pressure was rerouted as CC128 but not
650          used so far).
651        - Added initial support for real-time instrument scripts. The script VM
652          code is shared by all sampler engine implemementations, however only the
653          gig file format currently provides support for storing instrument scripts
654          (as LinuxSampler extension to the original GigaStudio 4 format).
655    
656      * Gigasampler format engine:
657        - implemented the "round robin keyboard" dimension
658        - fixed round robin and random dimensions for cases when number of
659          dimension zones is not a power of two
660        - made round robin use a counter for each region instead of each
661          key
662        - bugfix: pitch LFO controller "internal+aftertouch" was broken
663        - bugfix: filter keyboard tracking was broken
664        - filter performance fix (an unnecessary copy was made of the
665          filter parameters in each sub fragment)
666        - handle special case when pan parameter in gig file has max or
667          min value
668        - Exclusive Groups: don't ever stop voices of the same note,
669          doesn't sound naturally with a drumkit
670        - fixed EG1 modulation when attack or release is zero
671        - Fixed support for 'aftertouch' attenuation controller.
672        - Fixed crash that happened with velocity split sounds under certain
673          conditions (see also previous commit on libgig).
674        - fixed behaviour of filter LFO
675    
676      * SFZ format engine:
677        - Initial implementation (not usable yet)
678        - added support for v2 multiple stage envelope generators
679        - added a fine-tuned v1 envelope generator instead of using the
680          one from the gig engine
681        - fixed memory leak and memory handling errors
682        - added support for trigger=first, trigger=legato and sw_previous
683        - allow non-numerical key values ("C#4" for example)
684        - "key" opcode now sets pitch_keycenter too
685        - fixed error when unloading instrument with same sample used by
686          multiple regions
687        - added some opcode aliases, like loopmode for loop_mode, to be
688          more compatible
689        - added support for trigger=release and rt_decay
690        - added support for off_mode=normal
691        - added support for random, seq_position, seq_length and volume
692        - added v1 LFO opcodes to parser (no support in engine yet)
693        - added support for amp_veltrack and amp_velcurve_N
694        - fine-tuned the default velocity curve
695        - added support for transpose
696        - fixed crash when using sw_down/up
697        - improved logic for sw_lokey/hikey/up/down/last
698        - added more v1 aliases to parser
699        - reduced memory usage for sfz data
700        - RT-safeness: avoid malloc in audio thread
701        - fixed a bug that could cause voice stealing to fail
702        - optimized sample lookup
703        - improved support for exclusive groups (group, off_by and
704          off_mode)
705        - added support for controller triggered regions (on_locc/on_hicc)
706        - added support for loop_mode=one_shot
707        - fixed playback of 16 bit wav files on big endian CPUs
708        - added support for Ogg Vorbis sample files
709        - use loop markers from sample file if loop_start and loop_end are
710          not set in sfz file
711        - implemeted filters. Filter types: lowpass, bandpass, bandreject
712          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
713          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
714          cutoff_cc, cutoff_chanaft.
715        - bugfix: zero ampeg_sustain didn't work
716        - added support for velocity effect on amplifier envelope time

1031        - Pass/preserve polyphonic variable data from respective "note" event
1032          handler to "release" event handler.
1033        - Fixed crash when using built-in script function "by_marks()".
1034    
1035      * Bug fixes:
1036        - Fixed crash which may occur when MIDI key + transpose is out of range
1037        - minor valgrind fixes
1038        - fixed crash which occurred when changing an already deployed sampler
1039          channel to a different engine type
1040        - fixed crash when deleting a sampler channel or changing engine
1041          type while an instrument load was in progress
1042        - bugfix: playing a note while changing the instrument could cause
1043          a crash, or give "Handing back unknown region" error messages
1044        - bugfix: calling SET VOICES (which Fantasia does on start and
1045          refresh) could cause instruments to be unloaded
1046        - Mac OS X: fixed name collision of enum in EffectControl and
1047          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1048        - Mac OS X: fixed hanging threads
1049        - Windows: disabled the previous thread fix on non-Mac systems, as
1050          it caused hanging threads on Windows
1051        - Fixed possible crashes due to corrupted MIDI/audio device list
1052          after MIDI/audio device creation failure
1053        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1054          instruments were uselessly precached with zero samples, however it still
1055          took the full preloading time and on 1st program change the respective
1056          instrument was completely reloaded again.
1057        - fixed handling of rapid bank select and program change messages
1058          sent to the same sampler channel (patch from the Open Octave
1059          project, slightly adjusted)
1060        - fixed crash when trying to create an effect instance with controls
1061          which min and/or max values depend on the sample rate
1062        - fixed bug #162
1063        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1064          multiple paths (#165)
1065        - thread safety fixes for the instrument loading thread
1066        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1067          (#176)
1068        - more thread safety fixes for the instrument loading thread
1069        - sfz/sf2 engine: fixed crash when using small audio fragment size
1070        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1071        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1072          introduced in previous fix)
1073        - fixed crash when a channel received a program change while
1074          playing a note in a key group
1075        - fixed erroneous error message piping in VoiceBase.h
1076          (labelled "Disk stream not available in time")
1077        - Update effects on sample rate & period size changes (to avoid
1078          crashes and noise on such transitions).
1079        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1080          (fixes #208)
1081        - Fixed bug in LSCP grammar definition which caused a statement like
1082          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1083          practically irrelevant, however it caused problems with the new LSCP
1084          shell's auto completion feature).
1085        - Fixed MIDI program change messages being ignored if quickly executed
1086          after each other (fixes #231).
1087    
1088    Version 1.0.0 (31 July 2009)
1089    
1090      * packaging changes:
1091        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1092          causing e.g. the libgig test to fail when
1093          "./configure --disable-jack-driver" was used
1094          (patch by Alexis Ballier)
1095        - fixed compilation with gcc 4.3
1096        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1097        - fixed configure so it detects x86_64 (#107)
1098        - fixes for building with newer MinGW versions
1099        - fix for building with bison 2.4 (#111)
1100        - fixed building with libgig installed in a non-standard directory
1101        - minor fix in configure for mmsystem.h detection on MinGW
1102        - Windows: look for editor plugins and Fantasia using base
1103          directory of liblinuxsampler dll (look in the same directory and one
1104          directory above)
1105        - configure script fix: removed unconditional use of SSE
1106        - fixed building with sqlite installed in a non-standard directory
1107        - when cross-compiling, don't try to create instruments.db
1108        - fix for new mingw-w64 version, which has usleep
1109    
1110      * general changes:
1111        - bugfix: on some POSIX systems instrument editor plugins refused to
1112          load as we used a non-portable Linux specific struct field
1113          (fixes bug #70, patch by Ronald Baljeu)
1114        - fixed endless loop which occured when loading an instrument editor
1115          plugin DLL on Windows systems failed
1116        - fixed memory leaks that occurred when liblinuxsampler was unloaded
1117        - optimized the SynchronizedConfig class so it doesn't wait
1118          unnecessarily long after an update
1119        - added support for notifying instrument editors on note-on / note-off
1120          events (e.g. to highlight the pressed keys on the virtual keyboard
1121          of gigedit)
1122        - added support for triggering notes by instrument editors (see above)
1123        - be verbose on DLL load errors (on Linux)
1124        - fixed di-harmonic triangle LFO implementation (this LFO implementation
1125          is only used by very few systems, most pick the int math
1126          implementation, which is usually faster)
1127        - fixes for audio drivers with varying buffer sizes
1128        - experimental support for running LinuxSampler as a DSSI, LV2 and
1129          VST plugin
1130        - notification events for stream/voice count statistics are now sent
1131          only when there are actual changes
1132        - added memory ordering constraints to improve stability on
1133          multi-core and multi-cpu systems
1134        - maximum voices and disk streams can now be altered at runtime
1135        - fixed CPU feature detection on x86_64 (maybe fixes #108)
1136        - automatic stacktrace mechanism is now turned off by default and can
1137          be switched on by command line option "--stacktrace" (the automatic
1138          stacktrace mechanism seems to be broken on most systems at the moment)
1139        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1140          a pointer to the launched InstrumentEditor object
1141        - added optional 3rd party user data parameter for following
1142          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1143          InstrumentEditor::Launch(),
1144          InstrumentManager::LaunchInstrumentEditor()
1145        - theoretical fix: made SynchronizedConfig follow C++0x memory
1146          model more strictly
1147        - fixes for using large audio device buffers
1148        - Windows: add the installation directory to the DLL search path
1149          when loading an editor plugin (solves problems with VST and
1150          gigedit on systems with other GTK versions installed)
1151        - updated linuxsampler man page
1152    
1153      * audio driver:
1154        - removed the nonsense audio channel constraint (which was hard coded to
1155          max. 100 audio channels) for most audio drivers
1156        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1157          opposed to the LSCP specs
1158        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1159          reflected the wrong value
1160        - fixed a memory management bug in ASIO driver
1161        - Makefile fix: JACK_CFLAGS wasn't used
1162        - JACK: use jack_client_open instead of the deprecated
1163          jack_client_new
1164        - added (experimental) CoreAudio driver
1165        - applied old fixes to the ASIO driver that were included in the
1166          previous binary release but accidentally never committed to CVS
1167          (fixes #117)
1168        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1169          win64)
1170        - VST: added support for sample rate and buffer size changes
1171        - VST: close editor (Fantasia) when the VST is removed
1172        - VST: avoid opening Fantasia more than once for each VST instance
1173        - VST: export main function as "main" on Linux too (fix for
1174          energyXT)
1175        - VST: changed number of output channels from one stereo to 16
1176          stereo
1177        - added channel routing, fxsends and midi maps to the settings
1178          stored in the plugin state
1179        - performance optimization of AudioChannel::MixTo() and
1180          AudioChannel::CopyTo() methods using GCC vector exensions
1181          (if available)
1182        - ASIO fixes: avoid initializing the device twice, avoid throwing
1183          exception when getting parameters from a disconnected device
1184    
1185      * MIDI driver:
1186        - added JACK MIDI driver
1187        - dispatch bank select as ordinary CC as well, the user might seriously
1188          want to (mis)use it for some purpose ("fixed" in all current MIDI
1189          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1190        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1191          CoreMidi or AU
1192        - fixed mingw-w64 compilation error in MME driver
1193        - made program change handling in MIDI thread real-time safe by
1194          moving the logic to a non-RT thread
1195        - fixed minor memory leak in ALSA driver
1196    
1197      * instruments database:
1198        - avoid time consuming samples scanning when adding instruments
1199          to the instruments database
1200        - added support for handling lost files in the instruments database
1201        - Implemented option for adding instruments in separate directories
1202          in the instruments database
1203          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1204        - work-around for missing fnmatch function on Windows to make
1205          instrument database compilable
1206        - added instrument database support on Windows
1207          works with both standalone mode and VST plugin.
1208          the instruments DB file is located in
1209          %USERPROFILE%\.linuxsampler\instruments.db which allows different
1210          databases for each windows user
1211          if no DB is present it automatically creates the .linuxsampler subdir
1212          and then creates an empty DB
1213        - fixed recursive import, which was broken on Windows
1214    
1215      * Gigasampler format engine:
1216        - fixed a memory leak that could happen when a channel was deleted
1217          while notes were playing
1218        - made it possible to load an instrument even if the audio thread
1219          isn't running
1220        - added partial support for the "Controller Triggered" MIDI rule,
1221          enough for piano gigs with pedal noise samples
1222        - minor fix: only mark FX sends as being modified if really the
1223          respective FX send MIDI controller was used
1224        - added support for GM global device volume SysEx message
1225          (can be selected at compile time to either apply globally to the
1226          whole sampler [default] or only to the sampler channels that are
1227          connected to the respective MIDI input port the SysEx message arrived
1228          on)
1229        - bugfix: notes triggered at position 0 in the audio buffer were
1230          sometimes wrongly killed in the same buffer, causing no sound to
1231          be played
1232        - added support for chromatic / drumkit mode Roland GS Sysex message
1233          which is usally used to switch a part between chromatic sounds and
1234          drumkit sounds (as opposed to their common default setting of MIDI
1235          part 10 being a drumkit part and all other ones chromatic parts), in
1236          LS however one can switch between the first 16 MIDI instrument maps
1237          defined for the sampler
1238        - made it possible to create multiple sample channels even if the
1239          audio thread isn't running
1240        - fixed crash when removing channel with active voices (#116)
1241        - bugfix: on sample reference changes (instrument editor), only
1242          un-cache the respective sample if it's really not used by any
1243          sampler engine anymore
1244        - re-cache samples in case they were changed by an instrument editor,
1245          e.g. when a sample was added while playing (#82)
1246        - fixed hanging notes which occured when note-off event had the exact
1247          same time stamp as the voice's note-on event and occured both in the
1248          same audio fragment cycle (fixes bug #112)
1249        - added support for the "fine tune" and "pitch bend range"
1250          instrument-level gig parameters
1251        - fixed minor artifacts in pitch bend handling
1252        - added support for GS Reset SysEx message
1253        - allow gig files to use unlimited downward pitch shifting
1254        - added a limit check for upward pitch shifting
1255        - bugfix: sometimes, when playing a note twice fast, the second
1256          note was silent
1257        - fixed crash happening when a pitch bend event arrived at the
1258          same time a new instrument was loading
1259    
1260      * LSCP server:
1261        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1262          react on MIDI data arriving on certain sampler channels (so far only
1263          Note-On and Note-Off events are sent via this LSCP event)
1264        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1265          react on MIDI data arriving on certain MIDI input devices (so far only
1266          Note-On and Note-Off events are sent via this LSCP event)
1267        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1268          SET DB_INSTRUMENT FILE_PATH
1269        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1270          frontends to send MIDI messages to specific sampler channel
1271        - added two additional fields to GET FILE INSTRUMENT INFO command -
1272          KEY_BINDINGS and KEYSWITCH_BINDINGS
1273        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1274          was incorrect
1275        - Optimized the retrieval of the MIDI instrument mappings
1276        - added new LSCP command "SET VOICES" to globally alter the maximum
1277          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1278          be triggered respectively
1279        - added new LSCP command "SET STREAMS" to globally alter the maximum
1280          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1281          which will be triggered respectively
1282        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1283          a gigedit file dialog is opened)
1284        - close all connections when LSCPServer is deleted
1285        - hard close of all sockets on exit
1286        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1287          driver
1288    
1289      * Bug fixes:
1290        - fixed a crash which occurs when removing a sampler channel waiting
1291          to start instrument loading after another channel
1292        - fixed a crash which occurs when removing a sampler channel with
1293          instrument loading in progress (bug #113)
1294        - fixed termination caused by uncaught exception when adding MIDI
1295          instrument with PERSISTENT load mode
1296        - fixed possible iterator invalidations when resetting the sampler
1297        - fixed memory leaks when issuing the following LSCP commands:
1298          GET AUDIO_OUTPUT_DRIVER INFO
1299          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1300          GET MIDI_INPUT_DRIVER INFO
1301          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1302        - fixed possible compilation error when sqlite is not present
1303        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1304        - fixed crash when changing the audio output device of a sampler
1305          channel with loaded instrument and start playing notes
1306        - fixed endless loop in Engine::SuspendAll() (bug #120)
1307        - fixed a low-level atomic load function that was broken on 64-bit
1308          PowerPC, which probably could cause crashes on that platform
1309        - fixed a memory management error which could cause a crash when a
1310          plugin was unloaded
1311        - bugfix: two private structs had the same name, which could cause
1312          problems if the linker chose the wrong constructor
1313        - fixed low-level ConditionServer usage bug that caused lockups on
1314          Windows
1315    
1316    
1317    Version 0.5.1 (6 December 2007)
1318    
1319      * packaging changes:
1320        - added autoconf checks for pthread library
1321        - added autoconf check for pthread bug found on certain NPTL-enabled
1322          glibc versions (see Gentoo bug report #194076)
1323        - added autoconf checks for MS Windows
1324    
1325      * general changes:
1326        - bugfix: the thread used by an editor plugin didn't die when the
1327          editor closed
1328        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1329          out all the space. operator--() did not apply size_mask after
1330          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1331          order to avoid problems with the _NonVolatileReader functions.
1332        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1333          GetWriteSpace(). Since this function is currently only used in
1334          the stream's qsort() compare function, it didn't trigger any
1335          bugs.
1336        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1337          24bit mode too. Faster method to read 24bit words on little
1338          endian machines (x86): replaced 3 byte reads + shifts with a 1
1339          unaligned 32bit read and shift
1340        - experimental support for MS Windows (MIDI input via MME, AUDIO
1341          output via ASIO)
1342        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1343        - support for monitoring the total number of active disk streams
1344          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1345          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1346    
1347      * AUDIO driver:
1348        - added Windows ASIO low latency audio driver
1349    
1350      * MIDI driver:
1351        - added MME Windows MIDI driver
1352    
1353      * LSCP server:
1354        - added support for Windows style path / filenames, however with
1355          forward slash path separators instead of backslash
1356          (i.e. "C:/foo/bar.gig")
1357        - allow naughty liblscp to send non-string device parameters within
1358          apostrophes as well
1359        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1360          "LIST FILE INSTRUMENTS <file>" and
1361          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1362          about an arbitrary instrument file on the system where the sampler is
1363          running on
1364    
1365    Version 0.5.0 (15 October 2007)
1366    
1367      * packaging changes:
1368        - config.h is not going to be installed along with liblinuxsampler's
1369          API header files anymore
1370        - only the API relevant header (and source) files will be exported to
1371          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1372        - added completely new XCode project files for Mac OSX which is now
1373          capable to execute our autoconf environment, thus no need anymore
1374          to maintain the compile time configuration file (osx/version.h) for
1375          OSX manually (patch by Toshi Nagata)
1376        - fixed buggy boolean --enable-foo / --disable-foo configure script
1377          parameters
1378        - global.h now only covers global definitions that are needed for the
1379          C++ API header files, all implementation internal global definitions
1380          are now in global_private.h
1381        - atomic.h is not exposed to the C++ API anymore
1382        - no need to include config.h anymore for using LS's API header files
1383        - fixed warnings in API doc generation
1384

1412        - Implemented new, improved notification system
1413        - fixed compilation errors regarding OSX
1414          (patch by Toshi Nagata)
1415        - implemented instruments database
1416        - added support for escape sequences to the instruments database
1417        - added highly experimental support for on-the-fly instrument editing
1418          within the sampler's process (by using instrument editor plugins),
1419          you'll notice the new "Registered instrument editors:" message on
1420          startup, added a new LSCP command:
1421          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1422          to spawn a matching instrument editor for the instrument on the
1423          given sampler channel, the plugin path can be overridden at compile
1424          time with ./configure --enable-plugin-dir=/some/dir
1425        - added experimental code for synchronizing instrument editors hosted
1426          in the sampler's process to safely edit instruments while playing
1427          without a crash (hopefully) by either suspending single regions
1428          wherever possible or if unavoidable whole engine(s)
1429        - fixed several issues in fundamental "Thread" class: set scheduling
1430          policy and priority on thread level, set a minimum stack size for
1431          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1432          threads simply inherited properties of starting thread instead of
1433          setting their own policy and priority
1434        - minor fix in our automatic stack trace mechanism on crashes, the
1435          main process did not wait for the stack trace process to finish
1436          its output
1437        - fixed some minor memory leaks
1438        - reenabled assembly features support, at the moment only for
1439          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1440        - minor assembly fix in x86 features detection (don't use the PIC
1441          register, to avoid relocations in the text segment at runtime)
1442        - POSIX callback functions of Thread.h are hidden

1447      * audio driver:
1448        - the ALSA audio output driver parameters now reflect the correct
1449          parameter value ranges for the respective selected sound card
1450          (patch by Till Wimmer, a bit fixed and extended)

1467        - minor fix of EGDecay (patch by Toshi Nagata)
1468        - fixed compiler error when --enable-override-filter-type was
1469          supplied to the configure script (fixes #46)
1470        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1471          instead of a fix value
1472        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1473          127 (solo mode) only kill voices if the respective mode really
1474          changed
1475    
1476      * LSCP server:
1477        - fixed compile time error for old Bison versions
1478          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1479        - parser now supports extended ASCII character set
1480          (up to ASCII code 255, i.e. includes now umlauts and accents)
1481        - filename arguments in LSCP commands now allow to use escape
1482          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1483          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1484          code value like \xf2) (fixes bug #24)
1485        - the following LSCP commands now also support escape sequences for at
1486          least one of their text-based parameters (i.e. name, description):
1487          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1488          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1489          "SET DB_INSTRUMENT_DIRECTORY NAME",
1490          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1491          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1492          "FIND DB_INSTRUMENT_DIRECTORIES"
1493        - returns verbose syntax errors (line and column where syntax error
1494          occured, the unexpected character and the actually expected, possible
1495          character(s), the latter only if less than 5 possibilities)
1496        - made sure that LSCP syntax is not affected by gigedit locale
1497          settings
1498        - bugfix regarding strings parameter lists: all comma separated lists
1499          of strings were treated as being one string containing commas
1500          (fixes #57)

1502    * Bug fixes:    * Bug fixes:
1503      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
1504      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
1505        channel audio output device"        channel audio output device"
1506        - fixed a crash which occurs when reassigning the same engine
1507          on a sampler channel with connected MIDI device
1508        - fixed a crash which occurs when changing the number of ports of a MIDI
1509          device connected to a sampler channel to number less then or equal
1510          to the index of the port to which the sampler channel is connected.
1511        - The previous bindings were not been disconnected when altering
1512          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1513          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1514        - The active stream/voice count statistic was incorrect.
1515        - notification events were not been sent for some sampler
1516          channel changes
1517        - added default min and max values to restrict the number of allowed
1518          audio output channels and MIDI input ports
1519        - the connection to the PCM interface is now closed when destroying
1520          an audio output device
1521        - files with slash in their path or filename could not be loaded
1522
