* Event:Init(): memset() entire Event::Param union to zero instead of trying
  to do that for its individual members; the latter became error prone due
  to the union's growing complexity meanwhile.

* Bumped version (2.1.1.svn27).

1 schoenebeck 3548 Version SVN trunk (?)
2    
3     * general changes:
4     - Fixed compiler error in Pool.h.
5 schoenebeck 3581 - Require C++14 compiler support.
6 schoenebeck 3557 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 schoenebeck 3581 for checking in configure for C++14 support (as mandatory
8 schoenebeck 3557 requirement) and automatically adds compiler argument if required
9 schoenebeck 3581 (e.g. -std=C++14).
10 schoenebeck 3575 - 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 schoenebeck 3612 - 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 schoenebeck 3614 - 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 schoenebeck 3639 - Using now cubic interpolation as resampling algorithm by default; and
30     linear interpolation is deprecated now.
31 schoenebeck 3686 - 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 schoenebeck 3550
35 schoenebeck 3551 * Real-time instrument scripts:
36     - Added method ScriptVM::setExitResultEnabled() which allows to
37     explicitly enable the built-in exit() function to optionally accept
38     one function argument; the value of the passed exit() function
39     argument will then become available by calling
40     VMExecContext::exitResult() after script execution.
41 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
42 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
43     with a regular character (a-z or A-Z); starting them with a digit or
44     underscore is not allowed.
45     - NKSP parser fix: equal comparison operator "=" and not equal comparison
46     operator "#" must only accept integer operands.
47     - NKSP language: Implemented support for standard units like Hertz, seconds,
48     Bel including support for metric unit prefixes; so one can now e.g.
49     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
50     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
51     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
52     - NKSP language: Introduced "final" operator "!" which is specifically
53     intended for synthesis parameter values to denote that the synthesis
54     parameter value is intended to be the "final" value for that synthesis
55     parameter that should explicitly be used by the engine and thus causing
56     the sampler engine to ignore all other modulation sources for the same
57     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
58     variable or formula with this new "!" operator the expression is marked as
59     being "final".
60 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
61     and their potential metric prefix token.
62 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
63     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
64     - NKSP language: Added support for NKSP real number (floating point) script
65     variables (declare ~foo).
66     - NKSP language: Added support for NKSP real number (floating point) array
67     script variables (declare ?foo[]).
68     - Built-in script function "message()" accepts now real number argument as
69     well.
70     - Added built-in script function "real_to_int()" and its short hand form
71     "int()" for casting from real number to integer in NKSP scripts.
72     - Added built-in script function "int_to_real()" and its short hand form
73     "real()" for casting from integer to real number in NKSP scripts.
74 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
75     argument as well.
76 schoenebeck 3577 - Built-in script functions may have a different return type depending on
77     the arguments passed to the function.
78     - Built-in script function "abs()" optionally accepts and returns real
79     number.
80     - Built-in script functions "min()" and "max()" optionally accept real
81     number arguments and return real number as result in that case.
82 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
83     built-in functions (added methods VMFunction::returnUnitType() and
84     VMFunction::returnsFinal() for that purpose which must be implemented by
85     built-in function implementations).
86     - NKSP language: Allow metric unit prefixes of numeric scalar and array
87     variables to be changed freely at runtime (unlike unit types like Hz etc.
88     which are still sticky, parse-time features of variables which cannot be
89     changed at runtime for the intentional sake of determinism).
90     - NKSP language: 'final' values are prohibited for array variables for now
91     (attempt causes a parsers error).
92     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
93     conditions of runtime control structures like if(), while(), select()
94     (attempt causes a parser error).
95     - NKSP VM API: Allow built-in functions to perform their own, individual
96     parse time checks of arguments going to be passed to the function at
97     runtime (added method VMFunction::checkArgs() for that purpose).
98     - NKSP language: raise parser warning if only one operand of binary
99     operators (like logical 'or' comparison) contain a 'final' value (because
100     it would always yield in a 'final' result in such cases).
101     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
102     different metric unit prefixes, which will behave as expected (e.g.
103     result of expression '1000us < 2ms' is true).
104     - NKSP language: Allow adding values with different metric unit prefixes
105     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
106     - NKSP language: Allow subtracting values with different metric unit
107     prefixes (e.g. result of expression '1ms - 20us' is '980us').
108     - NKSP language: Allow multiplying with any metric unit prefixes
109     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
110     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
111     we don't have any considerable practical use for a term like '4s^2'
112     (hence any attempt multiplying two unit types still causes parser error).
113     - NKSP language: Allow dividing by any metric unit prefixes and allow
114     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
115     yields in unit free result '8'). So this is now a way to cast units away
116     e.g. for passing the result to other expressions, certain function calls
117     or variables which are not accepting any units (or that specific unit).
118     - NKSP language: integer arrays and real number arrays can now be converted
119     to strings (e.g. for dumping their content with message() calls for
120     script debugging purposes).
121     - NKSP language: expressions and variables with units are now correctly
122     casted to strings (e.g. with message() calls).
123     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
124     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
125     floating point tolerances into account.
126     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
127     VMScalarNumberExpr::evalCastReal().
128     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
129     'VMIntArrayExpr' and 'VMRealArrayExpr'.
130     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
131     unitFactor() (runtime) methods.
132     - Built-in function "exit()" supports now returning units and 'final'ness
133     for test cases.
134     - The following built-in functions support now units as well: "abs()",
135     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
136     "real_to_int()", "int()", "int_to_real()" and "real()".
137     - Built-in functions "array_equal()", "search()" and "sort()" support now
138     real number arrays (correctly) as well.
139     - Added individual parse time checks of arguments to be passed to built-in
140     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
141     "array_equal()" and "search()" specific for their individual purposes.
142 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
143     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
144     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
145     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
146     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
147     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
148     isScalarNumber() -> isNumber()).
149 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
150     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
151     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
152     as convenient methods for automatically converting values to expected
153     metric value basis.
154     - Built-in function "wait()" accepts now both integers and real numbers as
155     argument.
156 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
157     VMFunction::argType(vmint iArg) which was already superseded by its new
158     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
159     - NKSP parser: if wrong argument type was passed to a built-in function and
160     that built-in function accepts more than one data type for the argument,
161     then show all supported data types as parser error message.
162 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
163     unit type as well for its 3rd and 4th function arguments.
164     - The following built-in functions accept now real numbers as well for their
165     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
166     "change_attack()", "change_decay()", "change_release()",
167     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
168     "change_cutoff_sustain()", "change_cutoff_release()",
169     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
170     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
171     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
172     - Fixed built-in function "change_play_pos()" not having accepted metric
173     prefixes at all.
174 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
175     with unit type (for their 2nd argument) as if they were relative values
176     (that is as if they were passed without a unit type): "change_attack()",
177     "change_decay()", "change_release()", "change_cutoff_attack()",
178     "change_cutoff_decay()", "change_cutoff_release()".
179     - Fixed the following built-in functions having applied completely wrong
180     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
181     respective EGs being their modulation sink assume uint data type with
182     value range 0..1000 instead of 0.0..1.0.
183     - Added individual parse-time checks of function arguments for the following
184     built-in functions: "play_note()", "note_off()", "set_event_mark()",
185     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
186     "change_decay()", "change_release()", "change_cutoff_attack()",
187     "change_cutoff_decay()", "change_cutoff_release()",
188     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
189     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
190     "change_pan_time()".
191     - Don't abort function call if unit type was used and at the same time
192     'final' operator was omitted for the primary value argument of the
193     following built-in functions: "change_cutoff()", "change_attack()",
194     "change_decay()", "change_release()", "change_cutoff_attack()",
195     "change_cutoff_decay()", "change_cutoff_release()",
196     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
197     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
198     "change_pan_time()", instead imply 'final'ness at runtime and raise an
199     appropriate parser warning at parse time.
200 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
201     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
202     "cos()", "tan()", "asin()", "acos()", "atan()".
203     - Added built-in script real number constant "~NI_MATH_PI".
204     - Added built-in script real number constant "~NI_MATH_E".
205 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
206 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
207 schoenebeck 3551
208 schoenebeck 3550 * test cases:
209 schoenebeck 3548 - Fixed compiler errors in test cases.
210     - Updated README for how to compile & run test cases.
211     - Updated test case
212     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
213     expected behaviour of the Mutex class implementation (recursive
214     mutex type).
215 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
216     functions.
217 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
218 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
219     int_to_real(), real(), real_to_int() and int(), as well as for the
220     plus, minus and negate language operators.
221 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
222     'final' operator usage cases.
223     - Added NKSP test cases for (floating point tolerance aware) real number
224     equalness / unequalness comparison.
225 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
226     initialization of arrays.
227 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
228     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
229     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
230 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
231 schoenebeck 3548
232 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
233     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
234     behaviour for start_level_mid.
235 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
236     level (see discussion "GigaStudio LFO compatibility" on mailing list
237     from 2019-09-26 for details).
238 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
239     see discussion "GigaStudio LFO compatibility" on mailing list from
240     2019-09-26 for details).
241 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
242     either sine [default], triangle, saw or square).
243     - Format extension: Added support for LFO phase displacement (0��..360��).
244     - Format extension: Added support for flipping LFO polarity on LFO 3
245     (in the original gig format this was only available for LFO 1 and LFO 2).
246 schoenebeck 3646 - Format extension: Support for additional filter types:
247     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
248     bandreject 2-pole.
249 schoenebeck 3611
250 persson 3593 * SFZ format engine:
251     - Fixed support for regions with loccN/hiccN conditions on more than one
252     MIDI controller.
253    
254 schoenebeck 3612 * Benchmarks:
255     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
256     algorithm (since result of 2nd run was not accumulated).
257     - Added benchmark for saw wave (benchmarks/saw.cpp).
258     - Added benchmark for sine wave (benchmarks/sine.cpp).
259     - Added benchmark for square wave (benchmarks/square.cpp).
260     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
261     which are large enough on modern systems.
262    
263 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
264 schoenebeck 3381
265     * Real-time instrument scripts:
266     - Fixed behavior of built-in NKSP functions change_sustain(),
267     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
268     and change_cutoff_release().
269    
270 schoenebeck 3444 * general changes:
271     - Only play release trigger samples on sustain pedal up if this behaviour
272     was explicitly requested by the instrument (otherwise only on note-off).
273 persson 3455 - Fixed compiler warnings.
274     - Fixed compilation error when cross-compiling to Mac.
275 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
276     (see bug #169).
277     - LSCP doc: Be more clear describing the two distinct approaches
278     of using external vs. internal effects (see bug #169).
279 schoenebeck 3514 - "optional" class: Fixed comparison operators.
280 schoenebeck 3444
281 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
282     - Format extension: If requested by instrument then don't play release
283     trigger sample on note-off events.
284    
285 schoenebeck 3487 * SFZ format engine:
286     - Fixed memory leak when releasing samples
287     (fixes bug #307, patch by Jacek Roszkowski)
288 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
289     (fixes bug #308, patch by Jacek Roszkowski).
290 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
291     (fixes bug #310, patch by Jacek Roszkowski).
292 schoenebeck 3487
293 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
294 persson 2837
295 persson 2856 * SFZ format engine:
296     - added support for <global>, <master> and #define (patch by Alby M)
297 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
298     - Added support for sfz extension opcode 'script' which may be used to
299     load real-time instrument script file (NKSP script language).
300 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
301 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
302 persson 3291 - sfz parser: allow missing space between header and opcode
303 persson 2856
304 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
305 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
306     cutoff settings.
307 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
308     all if an up-pitch of more than 40 semi tones was requested (I don't
309     think there is any stock gig sound that requires this behavior to
310     resemble its original sound).
311 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
312     be aborted (as LinuxSampler extension to the original GigaStudio 4
313     format).
314 schoenebeck 3072
315 persson 2837 * general changes:
316     - fixed printf type errors (mostly in debug messages)
317 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
318 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
319     allowing to sort data efficiently in real-time safe manner.
320     - RTList class: added methods for moving/inserting elements to arbitrary
321     position within a list.
322     - RTList class: added method fromPtr() for creating an Iterator object from
323     a raw element pointer.
324     - Attempt to partly fix resetting engine channels vs. resetting engine, an
325     overall cleanup of the Reset*(), ConnectAudioDevice(),
326     DisconnectAudioDevice() API methods would still be desirable though,
327     because the current situation is still inconsistent and error prone.
328 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
329     being directly assigned to a keyboard key. This allows more fine graded
330     processing of voices, which is i.e. required for certain instrument
331     script features.
332 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
333     (CC #64) events.
334     - Fix: Release trigger voices can now also distinguish correctly between
335     note-off and sustain pedal up events.
336 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
337     (while slow rate of crossfade smoother is preserved) to allow quick
338     volume and pan changes by instrument scripts for instance.
339 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
340     properly and thus were ignored for certain uses.
341 schoenebeck 3018 - Added new C++ API method
342     VirtualMidiDevice::SendChannelPressureToSampler().
343 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
344     sub threads is 16-byte aligned
345 schoenebeck 3054 - fixed numerous compiler warnings
346 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
347 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
348     fixes potential undefined behavior.
349 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
350     have a valid sample mapped (fixes bug #252).
351     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
352 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
353     subsequent optional argument due to glibc's implementation oddity
354     which expects a "=" sign, but no space between them.
355 persson 2837
356 schoenebeck 2866 * packaging changes:
357     - removed unnecessary dependency to libuuid
358     (originated by libgig's usage of it)
359 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
360     auto detect whether it (sh/c)ould output its messages in color.
361 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
362     substitution variable.

367 schoenebeck 2871 * Real-time instrument scripts:
368     - Implemented scheduler for delayed MIDI events and for suspended scripts.
369     - Built-in script function "wait()": implemented support for function's
370     "duration-us" argument, thus scripts using this function are now
371     correctly resumed after the requested amount of microseconds.
372     - Built-in script function "play_note()": implemented support for
373     function's "duration-us" argument, thus notes triggered with this
374     argument are now correctly released after the requested amount of
375     microseconds.
376     - Fix: script events were not cleared when engine channel was reset,
377     potentially causing undefined behavior.
378     - Fixed crash which happened when trying to reference an undeclared
379     variable.
380 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
381     special value -1 for "duration-us" argument, which will cause the
382     triggered note to be released once the original note was released.
383 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
384     - Added new API method ScriptVM::syntaxHighlighting() which provides
385     a convenient syntax highlighting backend for external instrument
386     script editor applications.
387 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
388     - Extended parser issues to provide not only first line and first
389     column, but also last line and last column of issue (thus marking
390     the precise span of the issue within the source code).
391 schoenebeck 2902 - Reload script automatically after being modified by an instrument
392     editor.
393 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
394     like "on note end on".
395 schoenebeck 2931 - Implemented built-in script function "change_vol()".
396     - Implemented built-in script function "change_tune()".
397     - Implemented built-in script function "change_pan()".

399     - Implemented built-in script function "change_reso()".
400     - Implemented built-in script function "event_status()".
401     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
402     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
403     "event_status()" function.
404     - NKSP language: Added support for bitwise operators ".or.", ".and."
405     and ".not.".
406     - NKSP language scanner: Fixed IDs matching to require at least one
407     character (i.e. when matching function names or variable names).
408     - NKSP language scanner: disabled unusued rules.
409 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
410     be distinguished engine internally from "real" MIDI note on/off
411     events in order to avoid misbehaviors like hanging notes.
412 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
413     - Implemented built-in script variable "$NKSP_REAL_TIMER".
414     - Implemented built-in script variable "$NKSP_PERF_TIMER".

417     - Implemented built-in script function "dec()".
418     - NKSP language fix: division expressions were evaluated too often.
419     - NKSP language fix: string concatenation operator was right
420     associative instead of left (to right).
421 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
422     (i.e. "if end if").
423 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
424     - Implemented built-in script variable "$NI_CALLBACK_ID".
425     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
426     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

430     - Added built-in script constant "$NI_CB_TYPE_NOTE".
431     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

435     - Implemented built-in script function "change_decay()".
436     - Implemented built-in script function "change_release()".
437 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
438     synthesis parameter changes immediately in case the respective note
439     was triggered at the same time, instead of scheduling the parameter
440     change, especially because it would cause some parameter types's
441     changes either to be ramped (i.e. change_vol()) or other types even
442     to have not effect at all (i.e. change_attack()).
443 schoenebeck 2965 - Implemented built-in script function "sh_left()".
444     - Implemented built-in script function "sh_right()".
445 schoenebeck 2970 - Implemented built-in script function "min()".

447 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
448     was loaded.
449     - NKSP built-in wait() script function: abort script execution if
450     a negative or zero wait time was passed as argument (since this is
451     a common indication of a bug either of the script or even of the
452     engine, which could lead to RT instability or even worse).
453 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
454     threatening scripts.
455 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
456 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
457     initializer list to an array variable.
458 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
459 schoenebeck 3076 - Implemented built-in script function "in_range()".

463     - Implemented built-in script function "change_pitch_lfo_freq()".
464 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
465     - Implemented built-in script function "change_tune_time()".
466     - Implemented built-in script function "fade_in()".
467     - Implemented built-in script function "fade_out()".
468     - Fixed acceptance of wrong data type of parameters passed to built-in
469     script functions "change_vol()", "change_tune()", "change_pan()",
470     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
471     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
472     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
473 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
474     of its possible parameter selections.
475     - Added built-in script function "set_event_par()" and implemented some
476     of its possible parameter selections.
477 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
478 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
479 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
480     built-in function "ignore_controller()".
481 schoenebeck 3214 - Implemented built-in script function "change_velo()".
482     - Implemented built-in script function "change_note()".
483 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
484     intuitive behavior if used in combination with "change_vol_time()" or
485     "change_tune_time()" respectively: now tuning/volume changes are only
486     assigned (without delay) immediately to a new note if the respective
487     timing function has not been called before, otherwise the volume/tuning
488     changes are automatically faded (before, only the event's time stamp was
489     relevant).
490 schoenebeck 3221 - Implemented built-in script function "array_equal()".
491     - Implemented built-in script function "search()".
492     - Implemented built-in script function "sort()".
493     - NKSP Fix: Never suspend "init" event handlers.
494 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
495     available for gig format engine).
496 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
497     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
498     - Implemented built-in script function "change_vol_curve()".
499     - Implemented built-in script function "change_tune_curve()".
500 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
501     offset with argument 3, where special value -1 means to use the regular
502     sample offset as defined by the instrument file.
503 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
504     - Built-in variable $EVENT_NOTE is now a read-only variable.
505     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
506     - built-in "play_note()" function now accepts -2 for its fourth argument
507     (note duration) which means the life time of the note shall be sticked
508     to the requested note number of argument 1.
509     - Fix: built-in "play_note()" function now returns 0 as result value if
510     -1 was passed for its fourth argument (note duration) and the respective
511     parent note is already gone.
512 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
513 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
514     - NKSP language: Raise parser warning if array variable is accessed with
515     an index that exceeds the array's size.

517 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
518     code blocks.
519 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
520     another script handler by passing its callback ID.
521 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
522     "init" event handlers.
523 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
524     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
525     to retrieve all code blocks filtered out by the preprocessor.
526 schoenebeck 3293 - Added built-in script function "fork()".
527     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
528     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
529     - Fixed potential crash when accessing dynamic built-in array variables.
530 schoenebeck 3296 - Added built-in script function "callback_status()".
531     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
532     - Added built-in constant $CALLBACK_STATUS_QUEUE.
533     - Added built-in constant $CALLBACK_STATUS_RUNNING.
534 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
535     "change_decay()" and "change_release()" to i.e. allow passing 2000000
536     for doubling the respective time.
537 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
538     to a lexer start condition stack underrun.
539     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
540     USE_CODE_IF_NOT() preprocessor statements.
541 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
542     can be set to disable all subsequent built-in "message()" function calls
543     on preprocessor level.
544 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
545 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
546     to avoid the editor app to crash on ill-formed text input.
547 schoenebeck 3335 - Added built-in script function "change_pan_time()".
548     - Added built-in script function "change_pan_curve()".
549 schoenebeck 3360 - Added built-in script function "change_cutoff_attack()".
550     - Added built-in script function "change_cutoff_decay()".
551     - Added built-in script function "change_cutoff_sustain()".
552     - Added built-in script function "change_cutoff_release()".
553     - Added built-in script function "change_cutoff_lfo_depth()".
554     - Added built-in script function "change_cutoff_lfo_freq()".
555 schoenebeck 2871
556 schoenebeck 3050 * Instruments DB:
557     - Fixed memory access bug of general DB access code which lead to
558     undefined behavior.
559 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
560     - The instrument DB path of linuxsampler's --create-instruments-db argument
561     is now optional, if it is missing, then a default location is used.
562 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
563     - Added support for scanning Sound Font (.sf2) files.
564 schoenebeck 3101 - Fixed undefined DB transaction behavior.
565 schoenebeck 3050
566 schoenebeck 2787 Version 2.0.0 (15 July 2015)
567 schoenebeck 1993
568 persson 2086 * packaging changes:

570 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
571     - Mac OS X: fixed building outside source directory
572     - made sure all source files for hostplugins are included when
573     doing "make dist"
574     - removed empty directories left from the cvs to svn migration
575 persson 2185 - fixed compilation with gcc 4.6.1
576 persson 2203 - another "make dist" fix, for the LV2 plugin
577 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
578 persson 2197 - minor Makefile fix for building lscpparser when build and source
579     directories are separate
580 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
581     configure
582 persson 2208 - Mac OS X: Makefile fix for the install-strip target
583 persson 2335 - fixed compilation with gcc 4.7

587 persson 2365 - modernized configure script
588 persson 2378 - fixed linkage error when building with
589     LDFLAGS="-Wl,--no-undefined" (#190)
590 persson 2390 - fixed compilation with Clang 3.2
591 persson 2420 - removed usage of deprecated Automake variable INCLUDES

600     - support building with older jack versions
601     - support building with spaces in vst sdk path
602 persson 2519 - enabled automake 'subdir-objects' option and moved external
603     source references (vst, au, asio) from makefiles to cpp files,
604     in order to get rid of warnings from automake 1.14
605 persson 2382
606 persson 2086 * general changes:
607 iliev 2012 - Refactoring: moved the independent code from
608     the Gigasampler format engine to base classes
609 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
610     respective profiling code is currently broken
611 schoenebeck 2053 - Introduced support for optional environment variable
612     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
613     where the sampler shall look for instrument editor plugins
614     (patch by Luis Garrido, slightly modified).
615 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
616     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
617     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
618     note (in this implementation of the sampler its simply hard routed to
619     the 1st effect send of the sampler channel, no matter what the actual
620     effect type is)
621     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
622     note (in this implementation of the sampler its simply hard routed to
623     the 2nd effect send of the sampler channel, no matter what the actual
624     effect type is)
625 schoenebeck 2124 - implemented support for internal LADSPA effects
626 schoenebeck 2140 - raised limit of program change queue from 100 to 512
627     (as suggested by Alex Stone)
628 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
629 iliev 2296 - experimental support for per voice equalization
630 iliev 2306 - added command line option --exec-after-init
631 schoenebeck 2330 - Introduced new C++ API method:
632     EngineChannel::InstrumentFileName(int index)
633     allowing to retrieve the whole list of files used for the loaded
634     instrument on an engine channel (a.k.a. part). Some GigaStudio
635     instruments for example are splitted over several files like
636     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
637 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
638     - Added new C++ API method Sampler::GetGlobalMaxStreams().
639     - Added new C++ API method Sampler::SetGlobalMaxVoices().
640     - Added new C++ API method Sampler::SetGlobalMaxStreams().
641 schoenebeck 2377 - Various "const" and "restrict" optimizations.
642 persson 2382 - all engines: add pan CC value to instrument pan parameter before
643     applying panning, instead of using two separate pan functions in
644     series (#182)
645 persson 2427 - added a lock guard class for exception safe mutex handling and
646     used it everywhere appropriate
647 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
648     - Exposed scale tuning to C++ API (along to the already existing standard
649     SysEx way).
650 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
651     and broken for ppc64. (Seq_cst loads and stores are actually not
652     used in LS, so the bug wasn't noticable.)
653     - lsatomic.h: added ARMv7 support
654 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
655     added various new C++ methods for this new feature / design change, old
656     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
657     as deprecated but are still there and should provide full behavior
658     backward compatibility).
659     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
660     unsafe and caused compilation error with clang 2.x).
661 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
662 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
663     sampler from the command line by providing LSCP aware features.
664 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
665     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
666     - VirtualMidiDevice: Added support for pitch bend.
667 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
668     polyphonic key pressure events (so far polyphonic pressure was not
669     supported at all, and channel pressure was rerouted as CC128 but not
670     used so far).
671 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
672     code is shared by all sampler engine implemementations, however only the
673     gig file format currently provides support for storing instrument scripts
674     (as LinuxSampler extension to the original GigaStudio 4 format).
675 iliev 2012
676 persson 2043 * Gigasampler format engine:
677     - implemented the "round robin keyboard" dimension
678     - fixed round robin and random dimensions for cases when number of
679     dimension zones is not a power of two
680     - made round robin use a counter for each region instead of each
681     key
682 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
683     - bugfix: filter keyboard tracking was broken
684     - filter performance fix (an unnecessary copy was made of the
685     filter parameters in each sub fragment)
686     - handle special case when pan parameter in gig file has max or
687     min value
688 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
689     doesn't sound naturally with a drumkit
690 persson 2408 - fixed EG1 modulation when attack or release is zero
691 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
692 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
693     conditions (see also previous commit on libgig).
694 persson 2673 - fixed behaviour of filter LFO
695 persson 2043
696 schoenebeck 2047 * SFZ format engine:
697 iliev 2012 - Initial implementation (not usable yet)
698 persson 2055 - added support for v2 multiple stage envelope generators
699     - added a fine-tuned v1 envelope generator instead of using the
700     one from the gig engine
701 persson 2058 - fixed memory leak and memory handling errors
702 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
703 persson 2058 - allow non-numerical key values ("C#4" for example)
704     - "key" opcode now sets pitch_keycenter too
705     - fixed error when unloading instrument with same sample used by
706     multiple regions
707     - added some opcode aliases, like loopmode for loop_mode, to be
708     more compatible
709 persson 2061 - added support for trigger=release and rt_decay
710 persson 2063 - added support for off_mode=normal
711 persson 2072 - added support for random, seq_position, seq_length and volume
712     - added v1 LFO opcodes to parser (no support in engine yet)
713 persson 2082 - added support for amp_veltrack and amp_velcurve_N
714     - fine-tuned the default velocity curve
715 persson 2086 - added support for transpose
716     - fixed crash when using sw_down/up
717     - improved logic for sw_lokey/hikey/up/down/last
718     - added more v1 aliases to parser
719 persson 2091 - reduced memory usage for sfz data
720 persson 2101 - RT-safeness: avoid malloc in audio thread
721     - fixed a bug that could cause voice stealing to fail
722 persson 2106 - optimized sample lookup
723 persson 2114 - improved support for exclusive groups (group, off_by and

1072     after MIDI/audio device creation failure
1073 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1075     took the full preloading time and on 1st program change the respective
1076     instrument was completely reloaded again.
1077 persson 2277 - fixed handling of rapid bank select and program change messages
1078     sent to the same sampler channel (patch from the Open Octave

1100     (fixes #208)
1101 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1102     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1103     practically irrelevant, however it caused problems with the new LSCP
1104     shell's auto completion feature).
1105 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1106     after each other (fixes #231).

1158     stacktrace mechanism seems to be broken on most systems at the moment)
1159 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1160     a pointer to the launched InstrumentEditor object
1161 schoenebeck 1876 - added optional 3rd party user data parameter for following

1225     instrument database compilable
1226 schoenebeck 1930 - added instrument database support on Windows
1227     works with both standalone mode and VST plugin.
1228     the instruments DB file is located in
1229     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1230     databases for each windows user
1231     if no DB is present it automatically creates the .linuxsampler subdir
1232     and then creates an empty DB
1233 persson 1943 - fixed recursive import, which was broken on Windows
1234 iliev 1603
1235 persson 1644 * Gigasampler format engine:
1236     - fixed a memory leak that could happen when a channel was deleted
1237     while notes were playing

1243     respective FX send MIDI controller was used
1244 schoenebeck 1724 - added support for GM global device volume SysEx message
1245 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1246     whole sampler [default] or only to the sampler channels that are
1247     connected to the respective MIDI input port the SysEx message arrived
1248     on)
1249 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1250     sometimes wrongly killed in the same buffer, causing no sound to
1251     be played
1252 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1253     which is usally used to switch a part between chromatic sounds and
1254     drumkit sounds (as opposed to their common default setting of MIDI
1255     part 10 being a drumkit part and all other ones chromatic parts), in
1256     LS however one can switch between the first 16 MIDI instrument maps
1257     defined for the sampler
1258 persson 1764 - made it possible to create multiple sample channels even if the
1259     audio thread isn't running
1260 persson 1844 - fixed crash when removing channel with active voices (#116)

1262     un-cache the respective sample if it's really not used by any
1263     sampler engine anymore
1264     - re-cache samples in case they were changed by an instrument editor,
1265     e.g. when a sample was added while playing (#82)
1266 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1267     same time stamp as the voice's note-on event and occured both in the
1268     same audio fragment cycle (fixes bug #112)
1269 persson 1858 - added support for the "fine tune" and "pitch bend range"
1270     instrument-level gig parameters
1271     - fixed minor artifacts in pitch bend handling
1272 schoenebeck 1860 - added support for GS Reset SysEx message
1273 persson 1862 - allow gig files to use unlimited downward pitch shifting
1274     - added a limit check for upward pitch shifting
1275 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1276     note was silent
1277 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1278     same time a new instrument was loading
1279 persson 1644
1280 schoenebeck 1687 * LSCP server:
1281     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1282     react on MIDI data arriving on certain sampler channels (so far only
1283     Note-On and Note-Off events are sent via this LSCP event)
1284 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1285     react on MIDI data arriving on certain MIDI input devices (so far only
1286     Note-On and Note-Off events are sent via this LSCP event)
1287 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1288     SET DB_INSTRUMENT FILE_PATH
1289 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1290     frontends to send MIDI messages to specific sampler channel
1291     - added two additional fields to GET FILE INSTRUMENT INFO command -
1292     KEY_BINDINGS and KEYSWITCH_BINDINGS
1293 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1294     was incorrect
1295 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1296 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1297     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1298     be triggered respectively
1299     - added new LSCP command "SET STREAMS" to globally alter the maximum
1300     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1301     which will be triggered respectively
1302 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1303     a gigedit file dialog is opened)
1304 iliev 1848 - close all connections when LSCPServer is deleted
1305 iliev 1882 - hard close of all sockets on exit

1318     GET AUDIO_OUTPUT_DRIVER INFO
1319     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1320     GET MIDI_INPUT_DRIVER INFO
1321     GET MIDI_INPUT_DRIVER_PARAMETER INFO

1344 schoenebeck 1454
1345 persson 1455 * general changes:
1346     - bugfix: the thread used by an editor plugin didn't die when the
1347     editor closed
1348 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1349     out all the space. operator--() did not apply size_mask after
1350     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1351     order to avoid problems with the _NonVolatileReader functions.
1352     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1353     GetWriteSpace(). Since this function is currently only used in
1354     the stream's qsort() compare function, it didn't trigger any
1355     bugs.
1356     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1357     24bit mode too. Faster method to read 24bit words on little
1358     endian machines (x86): replaced 3 byte reads + shifts with a 1
1359     unaligned 32bit read and shift
1360     - experimental support for MS Windows (MIDI input via MME, AUDIO
1361     output via ASIO)
1362     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1363 iliev 1541 - support for monitoring the total number of active disk streams

1375     forward slash path separators instead of backslash
1376     (i.e. "C:/foo/bar.gig")
1377 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1378     apostrophes as well
1379 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1380     "LIST FILE INSTRUMENTS <file>" and
1381     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1382     about an arbitrary instrument file on the system where the sampler is
1383     running on

1388 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1389     API header files anymore

1391     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1392 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1393     capable to execute our autoconf environment, thus no need anymore
1394     to maintain the compile time configuration file (osx/version.h) for
1395     OSX manually (patch by Toshi Nagata)
1396 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1397     parameters
1398 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1399     C++ API header files, all implementation internal global definitions
1400     are now in global_private.h
1401     - atomic.h is not exposed to the C++ API anymore
1402     - no need to include config.h anymore for using LS's API header files

1405 schoenebeck 947 * general changes:
1406     - replaced the old, confusing MIDI program change mechanism by a
1407     flexible MIDI instrument mapper which allows to map arbitrary
1408 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1409 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1410     loaded on the respective channel when such MIDI program change
1411     messages arrive, beside that, each entry allows to define a life-time
1412     strategy for the instrument, so the user can define whether the
1413     instrument should i.e. be permanently loaded (to be able to switch
1414     quickly among sounds) or i.e. loaded just on demand when the
1415     respective program change arrives (to safe RAM space), as well as a
1416     global volume factor for each entry, so the user can adjust the volume
1417     dynamic of his mapped instrument collection without having to modify
1418 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1419     MIDI instrument maps and assign each sampler channel individually
1420     a certain map, so that i.e. separation of normal instruments and
1421     drumkits is possible
1422 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1423     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1424 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1425     due to a constant size RingBuffer FIFO which is now replaced by a
1426     dynamic (unlimited) size std::list FIFO
1427 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1428     output channels for being processed by external effect processors
1429     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1430     controllers
1431 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1432 iliev 1130 - Implemented new, improved notification system
1433 schoenebeck 1149 - fixed compilation errors regarding OSX
1434     (patch by Toshi Nagata)
1435 iliev 1161 - implemented instruments database
1436 iliev 1345 - added support for escape sequences to the instruments database
1437 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1438     within the sampler's process (by using instrument editor plugins),
1439     you'll notice the new "Registered instrument editors:" message on
1440 schoenebeck 1407 startup, added a new LSCP command:
1441     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1442 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1443     given sampler channel, the plugin path can be overridden at compile
1444     time with ./configure --enable-plugin-dir=/some/dir
1445 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1446     in the sampler's process to safely edit instruments while playing
1447     without a crash (hopefully) by either suspending single regions
1448     wherever possible or if unavoidable whole engine(s)
1449 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1450     policy and priority on thread level, set a minimum stack size for
1451     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1452     threads simply inherited properties of starting thread instead of
1453     setting their own policy and priority
1454 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1455     main process did not wait for the stack trace process to finish
1456     its output
1457 persson 1248 - fixed some minor memory leaks
1458 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1459     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1460 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1461     register, to avoid relocations in the text segment at runtime)
1462 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1463 schoenebeck 947
1464     * MIDI driver:
1465     - dispatch bank select (MSB and LSB) messages
1466    
1467 schoenebeck 1049 * audio driver:
1468     - the ALSA audio output driver parameters now reflect the correct
1469     parameter value ranges for the respective selected sound card
1470     (patch by Till Wimmer, a bit fixed and extended)
1471    
1472 persson 951 * Gigasampler format engine:
1473     - if a filter is used and EG2 finishes before EG1, let the voice
1474     die when EG2 has finished (this fixes a problem with clicks and
1475     voice starvation for some gigs)
1476 persson 1038 - playback is no longer disabled during instrument loading
1477     - all notes playing on a channel that changes its instrument keep
1478     playing with the old instrument until they get a note off
1479     command
1480 persson 1039 - EG fix: a release value of zero could cause noises or crash
1481 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1482 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1483     above max sustain level, which means that there is a decay phase
1484     even if sustain is 100%
1485 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1486     noises or crashes
1487 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1488 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1489     supplied to the configure script (fixes #46)
1490 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1491     instead of a fix value
1492 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1493     127 (solo mode) only kill voices if the respective mode really
1494     changed
1495 persson 951
1496 schoenebeck 1244 * LSCP server:
1497     - fixed compile time error for old Bison versions
1498     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1499 schoenebeck 1245 - parser now supports extended ASCII character set
1500     (up to ASCII code 255, i.e. includes now umlauts and accents)
1501     - filename arguments in LSCP commands now allow to use escape
1502     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1503     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1504     code value like \xf2) (fixes bug #24)
1505 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1506     least one of their text-based parameters (i.e. name, description):
1507     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1508     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1509     "SET DB_INSTRUMENT_DIRECTORY NAME",
1510     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1511     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1512     "FIND DB_INSTRUMENT_DIRECTORIES"
1513 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1514     occured, the unexpected character and the actually expected, possible
1515     character(s), the latter only if less than 5 possibilities)
1516 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1517     settings
1518 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1519     of strings were treated as being one string containing commas
1520     (fixes #57)
1521 schoenebeck 1244
1522 iliev 959 * Bug fixes:
1523     - fixed crash occurring on certain LSCP scripts (Bug 39)
1524 persson 1038 - another thread safety fix for lscp "load engine" and "set
1525     channel audio output device"
1526 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1527     on a sampler channel with connected MIDI device
1528 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1529     device connected to a sampler channel to number less then or equal
1530     to the index of the port to which the sampler channel is connected.
1531 iliev 1296 - The previous bindings were not been disconnected when altering
1532     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1533     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1534 iliev 1297 - The active stream/voice count statistic was incorrect.
1535 iliev 1298 - notification events were not been sent for some sampler
1536     channel changes
1537 iliev 1305 - added default min and max values to restrict the number of allowed
1538     audio output channels and MIDI input ports
1539 iliev 1306 - the connection to the PCM interface is now closed when destroying
1540     an audio output device
1541 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1542 iliev 959
1543 schoenebeck 1221 * test cases:
1544     - updated and fixed (haven't been touched in a while)
1545    
1546 schoenebeck 937 Version 0.4.0 (24 November 2006)
1547 persson 696
1548 schoenebeck 697 * packaging changes:
1549 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1550     to post-(un)install steps; added devel package for liblinuxsampler;
1551     to linuxsampler.spec (RPM)
1552 schoenebeck 697 - install necessary development header files for allowing 3rd party
1553     applications to link against liblinuxsampler
1554     - liblinuxsampler's API documentation can be generated with 'make docs'
1555     (Doxygen required)
1556 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1557     implementation (currently either an integer math solution or a
1558     di-harmonic approximation), automatic detection can be overriden
1559     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1560     configure script argument though (mandatory for cross-compilation)
1561 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1562     provided some on his own (as CXXFLAGS)
1563 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1564     messages
1565 schoenebeck 852 - added compile time options to allow disabling the various audio and
1566     MIDI drivers
1567 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1568     (patch by Ebrahim Mayat)
1569 schoenebeck 697
1570 persson 696 * Gigasampler format engine:
1571 schoenebeck 738 - extensive synthesis optimization
1572     (reimplementation of EGs and LFO(s), removed synthesis parameter
1573     prerendering and the synthesis parameter matrix in general, splitting
1574     each audio fragment into subfragments now where each subfragment uses
1575 persson 830 constant pitch and filter coefficients. The volume coefficient is
1576     linearly interpolated inside a subfragment, unless
1577     --disable-interpolate-volume is set.)
1578 persson 696 - fine tuning of the EG modulation parameters
1579 persson 729 - improved filter cutoff calculation by adding support for the
1580     following gig parameters: Cutoff freq (used when no cutoff
1581     controller is defined), Control invert, Minimum cutoff, Velocity
1582 persson 791 curve and Velocity range. The keyboard tracking now scales
1583     cutoff frequency instead of resonance.
1584 persson 877 - added support for gig parameter Resonance.
1585 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1586 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1587     which can be overridden with --enable-global-attenuation
1588 persson 783 - EG fixes: made the length of "attack hold" stage more
1589     accurate. Release stage can now start before attack stage
1590 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1591     time now has a minimal value to prevent clicks.
1592 persson 799 - fixed pitch changes larger than one octave
1593 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1594     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1595     all modes can be altered via standard GM messages, that is CC5 for
1596     altering portamento time, CC65 for enabling / disabling portamento
1597     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1598 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1599     parameter) and crossfade
1600 persson 831 - added support for the "attenuation controller threshold" gig
1601     parameter
1602 persson 832 - added smoothing of volume changes caused by control change
1603     messages
1604 persson 865 - sample loop parameters are now taken from the DimensionRegion
1605     instead of the wave chunk
1606     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1607     not equal to a power of two
1608 persson 877 - reimplementation of the filter algorithm. The new filter is more
1609     accurate and supports all gig filter types, including bandreject
1610     and lowpass turbo.
1611 persson 903 - real support for 24 bit samples - samples are not truncated to
1612     16 bits anymore
1613     - support for aftertouch (channel pressure, not polyphonic
1614     aftertouch)
1615 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1616     amplifying from 0)
1617 persson 696
1618 schoenebeck 711 * LSCP server:
1619     - fixed application exit on broken pipe error (fixes bug #20)
1620 iliev 793 - fixed the notification messages delay due to lack of
1621     network activity (fixes bug #26)
1622 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1623     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1624 schoenebeck 711
1625 schoenebeck 838 * audio driver:
1626     - added aRts audio output driver (by no means RT safe)
1627    
1628 schoenebeck 775 * MIDI driver:
1629     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1630     messages several times instead of once
1631 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1632     for events (i.e. for offline rendering based MIDI drivers)
1633 persson 922 - added checks for bad MIDI data
1634 schoenebeck 775
1635 schoenebeck 900 * linuxsampler application:
1636     - show available sampler engine types on startup
1637    
1638 schoenebeck 705 * general changes:
1639     - support for muting sampler channels and solo mode of the same, two new
1640     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1641     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1642     introduced for this, the behavior is the same like on a mixer console
1643 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1644     --enable-process-muted-channels which can be used to enable the
1645     processing of muted channels.
1646 iliev 777 - support for sostenuto pedal
1647 iliev 779 - support for monitoring the total number of active voices
1648 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1649     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1650 persson 835 - fixed some memory management errors
1651 persson 841 - fixed some concurrency problems that could lead to crashes when
1652     LSCP commands were executed
1653 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1654     sampler channel (fixes bug #36)
1655 schoenebeck 705
1656 schoenebeck 692 Version 0.3.3 (15 July 2005)
1657 schoenebeck 686
1658     * packaging changes:
1659     - fixed compilation with gcc 4.0
1660    
1661 schoenebeck 687 * Gigasampler format engine:
1662     - LFO preprocessing was performed even though the respective LFO was
1663     disabled by the instrument patch (minor efficiency fix)
1664 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1665     for volume ramp downs in the same fragment (needed for current voice
1666     stealing implementation) then simply inform the user with a warning
1667     about possible click sounds and reduce the volume ramp down
1668     appropriately instead of cancelling the audio device connection
1669 schoenebeck 687
1670 schoenebeck 677 Version 0.3.2 (24 June 2005)
1671 schoenebeck 609
1672     * packaging changes:
1673     - updated autotools build files to compile on OS X
1674     (conditional compilation of CoreMIDI and MidiShare drivers)
1675 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1676     './configure --disable-asm' (definitely not recommended)
1677 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1678     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1679     (due to 'dist-bzip2' automake option)
1680 schoenebeck 649
1681     * Gigasampler format engine:
1682     - support for the gig parameters for "release velocity response" curves
1683     - fine tuning of the EGADSR envelope
1684     - volume of release triggered samples now depends on note-on velocity,
1685     note length and gig parameter "release trigger decay" instead of
1686     note-off velocity.
1687 schoenebeck 663 - revised voice stealing
1688     (fixes crash and endless loop caused by voice stealing)
1689 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1690 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1691     instead of when the respective voice is actually launched
1692     (fixes undefined behavior if stolen voices belonged to a key group -
1693     this case was followed by a "killed voice survived" error message)
1694 schoenebeck 669 - fixed minor issue with null/silence samples
1695     (those stole voices even though they don't need a voice at all which
1696     resulted in "voice stealing didn't work out" messages)
1697 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1698     instrument or audio output device change
1699 schoenebeck 654
1700 schoenebeck 620 * LSCP server:
1701 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1702 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1703 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1704 schoenebeck 609
1705 schoenebeck 668 * linuxsampler application:
1706     - added command line parameters --lscp-addr and --lscp-port to override
1707     default IP address and port of LSCP server
1708    
1709 schoenebeck 579 Version 0.3.1 (24 May 2005)
1710    
1711     * initial release
