* gig format extension: Support for additional filter types:
  lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
  bandreject 2-pole.

* Bumped version (2.1.1.svn24).

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 3550
32 schoenebeck 3551 * Real-time instrument scripts:
33     - Added method ScriptVM::setExitResultEnabled() which allows to
34     explicitly enable the built-in exit() function to optionally accept
35     one function argument; the value of the passed exit() function
36     argument will then become available by calling
37     VMExecContext::exitResult() after script execution.
38 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
39 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
40     with a regular character (a-z or A-Z); starting them with a digit or
41     underscore is not allowed.
42     - NKSP parser fix: equal comparison operator "=" and not equal comparison
43     operator "#" must only accept integer operands.
44     - NKSP language: Implemented support for standard units like Hertz, seconds,
45     Bel including support for metric unit prefixes; so one can now e.g.
46     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
47     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
48     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
49     - NKSP language: Introduced "final" operator "!" which is specifically
50     intended for synthesis parameter values to denote that the synthesis
51     parameter value is intended to be the "final" value for that synthesis
52     parameter that should explicitly be used by the engine and thus causing
53     the sampler engine to ignore all other modulation sources for the same
54     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
55     variable or formula with this new "!" operator the expression is marked as
56     being "final".
57 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
58     and their potential metric prefix token.
59 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
60     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
61     - NKSP language: Added support for NKSP real number (floating point) script
62     variables (declare ~foo).
63     - NKSP language: Added support for NKSP real number (floating point) array
64     script variables (declare ?foo[]).
65     - Built-in script function "message()" accepts now real number argument as
66     well.
67     - Added built-in script function "real_to_int()" and its short hand form
68     "int()" for casting from real number to integer in NKSP scripts.
69     - Added built-in script function "int_to_real()" and its short hand form
70     "real()" for casting from integer to real number in NKSP scripts.
71 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
72     argument as well.
73 schoenebeck 3577 - Built-in script functions may have a different return type depending on
74     the arguments passed to the function.
75     - Built-in script function "abs()" optionally accepts and returns real
76     number.
77     - Built-in script functions "min()" and "max()" optionally accept real
78     number arguments and return real number as result in that case.
79 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
80     built-in functions (added methods VMFunction::returnUnitType() and
81     VMFunction::returnsFinal() for that purpose which must be implemented by
82     built-in function implementations).
83     - NKSP language: Allow metric unit prefixes of numeric scalar and array
84     variables to be changed freely at runtime (unlike unit types like Hz etc.
85     which are still sticky, parse-time features of variables which cannot be
86     changed at runtime for the intentional sake of determinism).
87     - NKSP language: 'final' values are prohibited for array variables for now
88     (attempt causes a parsers error).
89     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
90     conditions of runtime control structures like if(), while(), select()
91     (attempt causes a parser error).
92     - NKSP VM API: Allow built-in functions to perform their own, individual
93     parse time checks of arguments going to be passed to the function at
94     runtime (added method VMFunction::checkArgs() for that purpose).
95     - NKSP language: raise parser warning if only one operand of binary
96     operators (like logical 'or' comparison) contain a 'final' value (because
97     it would always yield in a 'final' result in such cases).
98     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
99     different metric unit prefixes, which will behave as expected (e.g.
100     result of expression '1000us < 2ms' is true).
101     - NKSP language: Allow adding values with different metric unit prefixes
102     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
103     - NKSP language: Allow subtracting values with different metric unit
104     prefixes (e.g. result of expression '1ms - 20us' is '980us').
105     - NKSP language: Allow multiplying with any metric unit prefixes
106     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
107     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
108     we don't have any considerable practical use for a term like '4s^2'
109     (hence any attempt multiplying two unit types still causes parser error).
110     - NKSP language: Allow dividing by any metric unit prefixes and allow
111     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
112     yields in unit free result '8'). So this is now a way to cast units away
113     e.g. for passing the result to other expressions, certain function calls
114     or variables which are not accepting any units (or that specific unit).
115     - NKSP language: integer arrays and real number arrays can now be converted
116     to strings (e.g. for dumping their content with message() calls for
117     script debugging purposes).
118     - NKSP language: expressions and variables with units are now correctly
119     casted to strings (e.g. with message() calls).
120     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
121     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
122     floating point tolerances into account.
123     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
124     VMScalarNumberExpr::evalCastReal().
125     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
126     'VMIntArrayExpr' and 'VMRealArrayExpr'.
127     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
128     unitFactor() (runtime) methods.
129     - Built-in function "exit()" supports now returning units and 'final'ness
130     for test cases.
131     - The following built-in functions support now units as well: "abs()",
132     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
133     "real_to_int()", "int()", "int_to_real()" and "real()".
134     - Built-in functions "array_equal()", "search()" and "sort()" support now
135     real number arrays (correctly) as well.
136     - Added individual parse time checks of arguments to be passed to built-in
137     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
138     "array_equal()" and "search()" specific for their individual purposes.
139 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
140     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
141     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
142     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
143     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
144     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
145     isScalarNumber() -> isNumber()).
146 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
147     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
148     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
149     as convenient methods for automatically converting values to expected
150     metric value basis.
151     - Built-in function "wait()" accepts now both integers and real numbers as
152     argument.
153 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
154     VMFunction::argType(vmint iArg) which was already superseded by its new
155     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
156     - NKSP parser: if wrong argument type was passed to a built-in function and
157     that built-in function accepts more than one data type for the argument,
158     then show all supported data types as parser error message.
159 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
160     unit type as well for its 3rd and 4th function arguments.
161     - The following built-in functions accept now real numbers as well for their
162     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
163     "change_attack()", "change_decay()", "change_release()",
164     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
165     "change_cutoff_sustain()", "change_cutoff_release()",
166     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
167     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
168     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
169     - Fixed built-in function "change_play_pos()" not having accepted metric
170     prefixes at all.
171 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
172     with unit type (for their 2nd argument) as if they were relative values
173     (that is as if they were passed without a unit type): "change_attack()",
174     "change_decay()", "change_release()", "change_cutoff_attack()",
175     "change_cutoff_decay()", "change_cutoff_release()".
176     - Fixed the following built-in functions having applied completely wrong
177     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
178     respective EGs being their modulation sink assume uint data type with
179     value range 0..1000 instead of 0.0..1.0.
180     - Added individual parse-time checks of function arguments for the following
181     built-in functions: "play_note()", "note_off()", "set_event_mark()",
182     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
183     "change_decay()", "change_release()", "change_cutoff_attack()",
184     "change_cutoff_decay()", "change_cutoff_release()",
185     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
187     "change_pan_time()".
188     - Don't abort function call if unit type was used and at the same time
189     'final' operator was omitted for the primary value argument of the
190     following built-in functions: "change_cutoff()", "change_attack()",
191     "change_decay()", "change_release()", "change_cutoff_attack()",
192     "change_cutoff_decay()", "change_cutoff_release()",
193     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
194     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
195     "change_pan_time()", instead imply 'final'ness at runtime and raise an
196     appropriate parser warning at parse time.
197 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
198     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
199     "cos()", "tan()", "asin()", "acos()", "atan()".
200     - Added built-in script real number constant "~NI_MATH_PI".
201     - Added built-in script real number constant "~NI_MATH_E".
202 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
203 schoenebeck 3551
204 schoenebeck 3550 * test cases:
205 schoenebeck 3548 - Fixed compiler errors in test cases.
206     - Updated README for how to compile & run test cases.
207     - Updated test case
208     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
209     expected behaviour of the Mutex class implementation (recursive
210     mutex type).
211 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
212     functions.
213 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
214 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
215     int_to_real(), real(), real_to_int() and int(), as well as for the
216     plus, minus and negate language operators.
217 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
218     'final' operator usage cases.
219     - Added NKSP test cases for (floating point tolerance aware) real number
220     equalness / unequalness comparison.
221 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
222     initialization of arrays.
223 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
224     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
225     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
226 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
227 schoenebeck 3548
228 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
229     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
230     behaviour for start_level_mid.
231 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
232     level (see discussion "GigaStudio LFO compatibility" on mailing list
233     from 2019-09-26 for details).
234 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
235     see discussion "GigaStudio LFO compatibility" on mailing list from
236     2019-09-26 for details).
237 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
238     either sine [default], triangle, saw or square).
239     - Format extension: Added support for LFO phase displacement (0��..360��).
240     - Format extension: Added support for flipping LFO polarity on LFO 3
241     (in the original gig format this was only available for LFO 1 and LFO 2).
242 schoenebeck 3646 - Format extension: Support for additional filter types:

244     bandreject 2-pole.
245 schoenebeck 3611
246 persson 3593 * SFZ format engine:
247     - Fixed support for regions with loccN/hiccN conditions on more than one
248     MIDI controller.
249    
250 schoenebeck 3612 * Benchmarks:
251     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
252     algorithm (since result of 2nd run was not accumulated).
253     - Added benchmark for saw wave (benchmarks/saw.cpp).
254     - Added benchmark for sine wave (benchmarks/sine.cpp).
255     - Added benchmark for square wave (benchmarks/square.cpp).
256     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
257     which are large enough on modern systems.
258    
259 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
260 schoenebeck 3381
261     * Real-time instrument scripts:
262     - Fixed behavior of built-in NKSP functions change_sustain(),
263     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
264     and change_cutoff_release().
265    
266 schoenebeck 3444 * general changes:
267     - Only play release trigger samples on sustain pedal up if this behaviour
268     was explicitly requested by the instrument (otherwise only on note-off).
269 persson 3455 - Fixed compiler warnings.
270     - Fixed compilation error when cross-compiling to Mac.
271 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
272     (see bug #169).
273     - LSCP doc: Be more clear describing the two distinct approaches
274     of using external vs. internal effects (see bug #169).
275 schoenebeck 3514 - "optional" class: Fixed comparison operators.
276 schoenebeck 3444
277 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
278     - Format extension: If requested by instrument then don't play release
279     trigger sample on note-off events.
280    
281 schoenebeck 3487 * SFZ format engine:
282     - Fixed memory leak when releasing samples
283     (fixes bug #307, patch by Jacek Roszkowski)
284 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
285     (fixes bug #308, patch by Jacek Roszkowski).
286 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
287     (fixes bug #310, patch by Jacek Roszkowski).
288 schoenebeck 3487
289 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
290 persson 2837
291 persson 2856 * SFZ format engine:
292     - added support for <global>, <master> and #define (patch by Alby M)
293 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
294     - Added support for sfz extension opcode 'script' which may be used to
295     load real-time instrument script file (NKSP script language).
296 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
297 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
298 persson 3291 - sfz parser: allow missing space between header and opcode
299 persson 2856
300 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
301 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
302     cutoff settings.
303 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
304     all if an up-pitch of more than 40 semi tones was requested (I don't
305     think there is any stock gig sound that requires this behavior to
306     resemble its original sound).
307 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
308     be aborted (as LinuxSampler extension to the original GigaStudio 4
309     format).
310 schoenebeck 3072
311 persson 2837 * general changes:
312     - fixed printf type errors (mostly in debug messages)
313 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
314 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
315     allowing to sort data efficiently in real-time safe manner.
316     - RTList class: added methods for moving/inserting elements to arbitrary
317     position within a list.
318     - RTList class: added method fromPtr() for creating an Iterator object from
319     a raw element pointer.
320     - Attempt to partly fix resetting engine channels vs. resetting engine, an
321     overall cleanup of the Reset*(), ConnectAudioDevice(),
322     DisconnectAudioDevice() API methods would still be desirable though,
323     because the current situation is still inconsistent and error prone.
324 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
325     being directly assigned to a keyboard key. This allows more fine graded
326     processing of voices, which is i.e. required for certain instrument
327     script features.
328 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
329     (CC #64) events.
330     - Fix: Release trigger voices can now also distinguish correctly between
331     note-off and sustain pedal up events.
332 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
333     (while slow rate of crossfade smoother is preserved) to allow quick
334     volume and pan changes by instrument scripts for instance.
335 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
336     properly and thus were ignored for certain uses.
337 schoenebeck 3018 - Added new C++ API method
338     VirtualMidiDevice::SendChannelPressureToSampler().
339 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
340     sub threads is 16-byte aligned
341 schoenebeck 3054 - fixed numerous compiler warnings
342 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
343 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
344     fixes potential undefined behavior.
345 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
346     have a valid sample mapped (fixes bug #252).
347     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
348 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
349     subsequent optional argument due to glibc's implementation oddity
350     which expects a "=" sign, but no space between them.
351 persson 2837
352 schoenebeck 2866 * packaging changes:
353     - removed unnecessary dependency to libuuid
354     (originated by libgig's usage of it)
355 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
356     auto detect whether it (sh/c)ould output its messages in color.

363 schoenebeck 2871 * Real-time instrument scripts:
364     - Implemented scheduler for delayed MIDI events and for suspended scripts.
365     - Built-in script function "wait()": implemented support for function's
366     "duration-us" argument, thus scripts using this function are now
367     correctly resumed after the requested amount of microseconds.
368     - Built-in script function "play_note()": implemented support for
369     function's "duration-us" argument, thus notes triggered with this
370     argument are now correctly released after the requested amount of
371     microseconds.
372     - Fix: script events were not cleared when engine channel was reset,
373     potentially causing undefined behavior.
374     - Fixed crash which happened when trying to reference an undeclared
375     variable.
376 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing

378     triggered note to be released once the original note was released.
379 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
380     - Added new API method ScriptVM::syntaxHighlighting() which provides
381     a convenient syntax highlighting backend for external instrument
382     script editor applications.
383 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
384     - Extended parser issues to provide not only first line and first
385     column, but also last line and last column of issue (thus marking
386     the precise span of the issue within the source code).
387 schoenebeck 2902 - Reload script automatically after being modified by an instrument
388     editor.
389 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
390     like "on note end on".
391 schoenebeck 2931 - Implemented built-in script function "change_vol()".
392     - Implemented built-in script function "change_tune()".

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

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

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

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

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

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

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

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

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

704     more compatible
705 persson 2061 - added support for trigger=release and rt_decay
706 persson 2063 - added support for off_mode=normal
707 persson 2072 - added support for random, seq_position, seq_length and volume
708     - added v1 LFO opcodes to parser (no support in engine yet)
709 persson 2082 - added support for amp_veltrack and amp_velcurve_N
710     - fine-tuned the default velocity curve
711 persson 2086 - added support for transpose
712     - fixed crash when using sw_down/up
713     - improved logic for sw_lokey/hikey/up/down/last
714     - added more v1 aliases to parser
715 persson 2091 - reduced memory usage for sfz data
716 persson 2101 - RT-safeness: avoid malloc in audio thread
717     - fixed a bug that could cause voice stealing to fail
718 persson 2106 - optimized sample lookup
719 persson 2114 - improved support for exclusive groups (group, off_by and
720     off_mode)
721 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
722     - added support for loop_mode=one_shot
723 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs

1068     after MIDI/audio device creation failure
1069 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1071     took the full preloading time and on 1st program change the respective
1072     instrument was completely reloaded again.
1073 persson 2277 - fixed handling of rapid bank select and program change messages
1074     sent to the same sampler channel (patch from the Open Octave

1095 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1096     (fixes #208)
1097 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1098     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1099     practically irrelevant, however it caused problems with the new LSCP
1100     shell's auto completion feature).
1101 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1102     after each other (fixes #231).

1133     - optimized the SynchronizedConfig class so it doesn't wait
1134     unnecessarily long after an update
1135 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off

1154     stacktrace mechanism seems to be broken on most systems at the moment)
1155 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1156     a pointer to the launched InstrumentEditor object
1157 schoenebeck 1876 - added optional 3rd party user data parameter for following
1158     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

1221     instrument database compilable
1222 schoenebeck 1930 - added instrument database support on Windows
1223     works with both standalone mode and VST plugin.
1224     the instruments DB file is located in
1225     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1226     databases for each windows user
1227     if no DB is present it automatically creates the .linuxsampler subdir
1228     and then creates an empty DB
1229 persson 1943 - fixed recursive import, which was broken on Windows
1230 iliev 1603
1231 persson 1644 * Gigasampler format engine:
1232     - fixed a memory leak that could happen when a channel was deleted
1233     while notes were playing
1234 persson 1646 - made it possible to load an instrument even if the audio thread
1235     isn't running
1236 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,

1239     respective FX send MIDI controller was used
1240 schoenebeck 1724 - added support for GM global device volume SysEx message
1241 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1242     whole sampler [default] or only to the sampler channels that are
1243     connected to the respective MIDI input port the SysEx message arrived
1244     on)
1245 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1246     sometimes wrongly killed in the same buffer, causing no sound to
1247     be played
1248 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1249     which is usally used to switch a part between chromatic sounds and
1250     drumkit sounds (as opposed to their common default setting of MIDI
1251     part 10 being a drumkit part and all other ones chromatic parts), in
1252     LS however one can switch between the first 16 MIDI instrument maps
1253     defined for the sampler
1254 persson 1764 - made it possible to create multiple sample channels even if the
1255     audio thread isn't running
1256 persson 1844 - fixed crash when removing channel with active voices (#116)
1257 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1258     un-cache the respective sample if it's really not used by any
1259     sampler engine anymore
1260     - re-cache samples in case they were changed by an instrument editor,
1261     e.g. when a sample was added while playing (#82)
1262 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1263     same time stamp as the voice's note-on event and occured both in the
1264     same audio fragment cycle (fixes bug #112)
1265 persson 1858 - added support for the "fine tune" and "pitch bend range"
1266     instrument-level gig parameters
1267     - fixed minor artifacts in pitch bend handling
1268 schoenebeck 1860 - added support for GS Reset SysEx message
1269 persson 1862 - allow gig files to use unlimited downward pitch shifting
1270     - added a limit check for upward pitch shifting
1271 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1272     note was silent
1273 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1274     same time a new instrument was loading
1275 persson 1644
1276 schoenebeck 1687 * LSCP server:
1277     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1278     react on MIDI data arriving on certain sampler channels (so far only
1279     Note-On and Note-Off events are sent via this LSCP event)
1280 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1281     react on MIDI data arriving on certain MIDI input devices (so far only
1282     Note-On and Note-Off events are sent via this LSCP event)
1283 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1284     SET DB_INSTRUMENT FILE_PATH
1285 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1286     frontends to send MIDI messages to specific sampler channel
1287     - added two additional fields to GET FILE INSTRUMENT INFO command -
1288     KEY_BINDINGS and KEYSWITCH_BINDINGS
1289 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1290     was incorrect
1291 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1292 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1293     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1294     be triggered respectively
1295     - added new LSCP command "SET STREAMS" to globally alter the maximum
1296     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1297     which will be triggered respectively
1298 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1299     a gigedit file dialog is opened)
1300 iliev 1848 - close all connections when LSCPServer is deleted
1301 iliev 1882 - hard close of all sockets on exit
1302 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1303     driver
1304 schoenebeck 1687

1308 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1309     instrument loading in progress (bug #113)
1310 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1311     instrument with PERSISTENT load mode
1312 iliev 1835 - fixed possible iterator invalidations when resetting the sampler

1314     GET AUDIO_OUTPUT_DRIVER INFO
1315     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1316     GET MIDI_INPUT_DRIVER INFO
1317     GET MIDI_INPUT_DRIVER_PARAMETER INFO

1319 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1320 iliev 1847 - fixed crash when changing the audio output device of a sampler
1321     channel with loaded instrument and start playing notes
1322 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1323 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1324     PowerPC, which probably could cause crashes on that platform
1325 persson 1889 - fixed a memory management error which could cause a crash when a
1326     plugin was unloaded
1327 persson 1896 - bugfix: two private structs had the same name, which could cause

1339 senoner 1502 - added autoconf checks for MS Windows
1340 schoenebeck 1454
1341 persson 1455 * general changes:
1342     - bugfix: the thread used by an editor plugin didn't die when the
1343     editor closed
1344 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1345     out all the space. operator--() did not apply size_mask after
1346     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1347     order to avoid problems with the _NonVolatileReader functions.
1348     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1349     GetWriteSpace(). Since this function is currently only used in
1350     the stream's qsort() compare function, it didn't trigger any
1351     bugs.
1352     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1353     24bit mode too. Faster method to read 24bit words on little
1354     endian machines (x86): replaced 3 byte reads + shifts with a 1
1355     unaligned 32bit read and shift
1356     - experimental support for MS Windows (MIDI input via MME, AUDIO
1357     output via ASIO)
1358     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1359 iliev 1541 - support for monitoring the total number of active disk streams

1371     forward slash path separators instead of backslash
1372     (i.e. "C:/foo/bar.gig")
1373 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1374     apostrophes as well
1375 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1376     "LIST FILE INSTRUMENTS <file>" and
1377     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1378     about an arbitrary instrument file on the system where the sampler is
1379     running on
1380 schoenebeck 1471
1381 schoenebeck 1424 Version 0.5.0 (15 October 2007)

1383 schoenebeck 1065 * packaging changes:
1384 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1385     API header files anymore
1386 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1387     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1388 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1389     capable to execute our autoconf environment, thus no need anymore
1390     to maintain the compile time configuration file (osx/version.h) for
1391     OSX manually (patch by Toshi Nagata)
1392 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1393     parameters
1394 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1395     C++ API header files, all implementation internal global definitions
1396     are now in global_private.h
1397     - atomic.h is not exposed to the C++ API anymore
1398     - no need to include config.h anymore for using LS's API header files
1399     - fixed warnings in API doc generation
1400 schoenebeck 1065
1401 schoenebeck 947 * general changes:
1402     - replaced the old, confusing MIDI program change mechanism by a
1403     flexible MIDI instrument mapper which allows to map arbitrary
1404 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1405 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1406     loaded on the respective channel when such MIDI program change
1407     messages arrive, beside that, each entry allows to define a life-time
1408     strategy for the instrument, so the user can define whether the
1409     instrument should i.e. be permanently loaded (to be able to switch
1410     quickly among sounds) or i.e. loaded just on demand when the
1411     respective program change arrives (to safe RAM space), as well as a
1412     global volume factor for each entry, so the user can adjust the volume
1413     dynamic of his mapped instrument collection without having to modify
1414 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1415     MIDI instrument maps and assign each sampler channel individually
1416     a certain map, so that i.e. separation of normal instruments and
1417     drumkits is possible
1418 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1419     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1420 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1421     due to a constant size RingBuffer FIFO which is now replaced by a
1422     dynamic (unlimited) size std::list FIFO
1423 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1424     output channels for being processed by external effect processors
1425     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1426     controllers
1427 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1428 iliev 1130 - Implemented new, improved notification system
1429 schoenebeck 1149 - fixed compilation errors regarding OSX
1430     (patch by Toshi Nagata)
1431 iliev 1161 - implemented instruments database
1432 iliev 1345 - added support for escape sequences to the instruments database
1433 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1434     within the sampler's process (by using instrument editor plugins),
1435     you'll notice the new "Registered instrument editors:" message on
1436 schoenebeck 1407 startup, added a new LSCP command:
1437     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1438 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1439     given sampler channel, the plugin path can be overridden at compile
1440     time with ./configure --enable-plugin-dir=/some/dir
1441 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1442     in the sampler's process to safely edit instruments while playing
1443     without a crash (hopefully) by either suspending single regions
1444     wherever possible or if unavoidable whole engine(s)
1445 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1446     policy and priority on thread level, set a minimum stack size for
1447     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1448     threads simply inherited properties of starting thread instead of
1449     setting their own policy and priority
1450 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1451     main process did not wait for the stack trace process to finish
1452     its output
1453 persson 1248 - fixed some minor memory leaks
1454 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1455     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1456 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1457     register, to avoid relocations in the text segment at runtime)
1458 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1459 schoenebeck 947
1460     * MIDI driver:
1461     - dispatch bank select (MSB and LSB) messages
1462    
1463 schoenebeck 1049 * audio driver:
1464     - the ALSA audio output driver parameters now reflect the correct
1465     parameter value ranges for the respective selected sound card
1466     (patch by Till Wimmer, a bit fixed and extended)
1467    
1468 persson 951 * Gigasampler format engine:
1469     - if a filter is used and EG2 finishes before EG1, let the voice
1470     die when EG2 has finished (this fixes a problem with clicks and
1471     voice starvation for some gigs)
1472 persson 1038 - playback is no longer disabled during instrument loading
1473     - all notes playing on a channel that changes its instrument keep
1474     playing with the old instrument until they get a note off
1475     command
1476 persson 1039 - EG fix: a release value of zero could cause noises or crash
1477 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1478 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1479     above max sustain level, which means that there is a decay phase
1480     even if sustain is 100%
1481 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1482     noises or crashes
1483 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1484 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1485     supplied to the configure script (fixes #46)
1486 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1487     instead of a fix value
1488 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1489     127 (solo mode) only kill voices if the respective mode really
1490     changed
1491 persson 951
1492 schoenebeck 1244 * LSCP server:
1493     - fixed compile time error for old Bison versions
1494     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1495 schoenebeck 1245 - parser now supports extended ASCII character set
1496     (up to ASCII code 255, i.e. includes now umlauts and accents)
1497     - filename arguments in LSCP commands now allow to use escape
1498     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1499     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1500     code value like \xf2) (fixes bug #24)
1501 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1502     least one of their text-based parameters (i.e. name, description):
1503     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1504     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1505     "SET DB_INSTRUMENT_DIRECTORY NAME",
1506     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1507     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1508     "FIND DB_INSTRUMENT_DIRECTORIES"
1509 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1510     occured, the unexpected character and the actually expected, possible
1511     character(s), the latter only if less than 5 possibilities)
1512 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1513     settings
1514 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1515     of strings were treated as being one string containing commas
1516     (fixes #57)
1517 schoenebeck 1244
1518 iliev 959 * Bug fixes:
1519     - fixed crash occurring on certain LSCP scripts (Bug 39)
1520 persson 1038 - another thread safety fix for lscp "load engine" and "set
1521     channel audio output device"
1522 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1523     on a sampler channel with connected MIDI device
1524 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1525     device connected to a sampler channel to number less then or equal
1526     to the index of the port to which the sampler channel is connected.
1527 iliev 1296 - The previous bindings were not been disconnected when altering
1528     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1529     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1530 iliev 1297 - The active stream/voice count statistic was incorrect.
1531 iliev 1298 - notification events were not been sent for some sampler
1532     channel changes
1533 iliev 1305 - added default min and max values to restrict the number of allowed
1534     audio output channels and MIDI input ports
1535 iliev 1306 - the connection to the PCM interface is now closed when destroying
1536     an audio output device
1537 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1538 iliev 959
1539 schoenebeck 1221 * test cases:
1540     - updated and fixed (haven't been touched in a while)
1541    
1542 schoenebeck 937 Version 0.4.0 (24 November 2006)
1543 persson 696
1544 schoenebeck 697 * packaging changes:
1545 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1546     to post-(un)install steps; added devel package for liblinuxsampler;
1547     to linuxsampler.spec (RPM)
1548 schoenebeck 697 - install necessary development header files for allowing 3rd party
1549     applications to link against liblinuxsampler
1550     - liblinuxsampler's API documentation can be generated with 'make docs'
1551     (Doxygen required)
1552 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1553     implementation (currently either an integer math solution or a
1554     di-harmonic approximation), automatic detection can be overriden
1555     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1556     configure script argument though (mandatory for cross-compilation)
1557 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1558     provided some on his own (as CXXFLAGS)
1559 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1560     messages
1561 schoenebeck 852 - added compile time options to allow disabling the various audio and
1562     MIDI drivers
1563 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1564     (patch by Ebrahim Mayat)
1565 schoenebeck 697
1566 persson 696 * Gigasampler format engine:
1567 schoenebeck 738 - extensive synthesis optimization
1568     (reimplementation of EGs and LFO(s), removed synthesis parameter
1569     prerendering and the synthesis parameter matrix in general, splitting
1570     each audio fragment into subfragments now where each subfragment uses
1571 persson 830 constant pitch and filter coefficients. The volume coefficient is
1572     linearly interpolated inside a subfragment, unless
1573     --disable-interpolate-volume is set.)
1574 persson 696 - fine tuning of the EG modulation parameters
1575 persson 729 - improved filter cutoff calculation by adding support for the
1576     following gig parameters: Cutoff freq (used when no cutoff
1577     controller is defined), Control invert, Minimum cutoff, Velocity
1578 persson 791 curve and Velocity range. The keyboard tracking now scales
1579     cutoff frequency instead of resonance.
1580 persson 877 - added support for gig parameter Resonance.
1581 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1582 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1583     which can be overridden with --enable-global-attenuation
1584 persson 783 - EG fixes: made the length of "attack hold" stage more
1585     accurate. Release stage can now start before attack stage
1586 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1587     time now has a minimal value to prevent clicks.
1588 persson 799 - fixed pitch changes larger than one octave
1589 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1590     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1591     all modes can be altered via standard GM messages, that is CC5 for
1592     altering portamento time, CC65 for enabling / disabling portamento
1593     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1594 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1595     parameter) and crossfade
1596 persson 831 - added support for the "attenuation controller threshold" gig
1597     parameter
1598 persson 832 - added smoothing of volume changes caused by control change
1599     messages
1600 persson 865 - sample loop parameters are now taken from the DimensionRegion
1601     instead of the wave chunk
1602     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1603     not equal to a power of two
1604 persson 877 - reimplementation of the filter algorithm. The new filter is more
1605     accurate and supports all gig filter types, including bandreject
1606     and lowpass turbo.
1607 persson 903 - real support for 24 bit samples - samples are not truncated to
1608     16 bits anymore
1609     - support for aftertouch (channel pressure, not polyphonic
1610     aftertouch)
1611 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1612     amplifying from 0)
1613 persson 696
1614 schoenebeck 711 * LSCP server:
1615     - fixed application exit on broken pipe error (fixes bug #20)
1616 iliev 793 - fixed the notification messages delay due to lack of
1617     network activity (fixes bug #26)
1618 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1619     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1620 schoenebeck 711
1621 schoenebeck 838 * audio driver:
1622     - added aRts audio output driver (by no means RT safe)
1623    
1624 schoenebeck 775 * MIDI driver:
1625     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1626     messages several times instead of once
1627 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1628     for events (i.e. for offline rendering based MIDI drivers)
1629 persson 922 - added checks for bad MIDI data
1630 schoenebeck 775
1631 schoenebeck 900 * linuxsampler application:
1632     - show available sampler engine types on startup
1633    
1634 schoenebeck 705 * general changes:
1635     - support for muting sampler channels and solo mode of the same, two new
1636     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1637     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1638     introduced for this, the behavior is the same like on a mixer console
1639 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1640     --enable-process-muted-channels which can be used to enable the
1641     processing of muted channels.
1642 iliev 777 - support for sostenuto pedal
1643 iliev 779 - support for monitoring the total number of active voices
1644 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1645     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1646 persson 835 - fixed some memory management errors
1647 persson 841 - fixed some concurrency problems that could lead to crashes when
1648     LSCP commands were executed
1649 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1650     sampler channel (fixes bug #36)
1651 schoenebeck 705
1652 schoenebeck 692 Version 0.3.3 (15 July 2005)
1653 schoenebeck 686
1654     * packaging changes:
1655     - fixed compilation with gcc 4.0
1656    
1657 schoenebeck 687 * Gigasampler format engine:
1658     - LFO preprocessing was performed even though the respective LFO was
1659     disabled by the instrument patch (minor efficiency fix)
1660 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1661     for volume ramp downs in the same fragment (needed for current voice
1662     stealing implementation) then simply inform the user with a warning
1663     about possible click sounds and reduce the volume ramp down
1664     appropriately instead of cancelling the audio device connection
1665 schoenebeck 687
1666 schoenebeck 677 Version 0.3.2 (24 June 2005)
1667 schoenebeck 609
1668     * packaging changes:
1669     - updated autotools build files to compile on OS X
1670     (conditional compilation of CoreMIDI and MidiShare drivers)
1671 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1672     './configure --disable-asm' (definitely not recommended)
1673 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1674     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1675     (due to 'dist-bzip2' automake option)
1676 schoenebeck 649
1677     * Gigasampler format engine:
1678     - support for the gig parameters for "release velocity response" curves
1679     - fine tuning of the EGADSR envelope
1680     - volume of release triggered samples now depends on note-on velocity,
1681     note length and gig parameter "release trigger decay" instead of
1682     note-off velocity.
1683 schoenebeck 663 - revised voice stealing
1684     (fixes crash and endless loop caused by voice stealing)
1685 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1686 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1687     instead of when the respective voice is actually launched
1688     (fixes undefined behavior if stolen voices belonged to a key group -
1689     this case was followed by a "killed voice survived" error message)
1690 schoenebeck 669 - fixed minor issue with null/silence samples
1691     (those stole voices even though they don't need a voice at all which
1692     resulted in "voice stealing didn't work out" messages)
1693 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1694     instrument or audio output device change
1695 schoenebeck 654
1696 schoenebeck 620 * LSCP server:
1697 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1698 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1699 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1700 schoenebeck 609
1701 schoenebeck 668 * linuxsampler application:
1702     - added command line parameters --lscp-addr and --lscp-port to override
1703     default IP address and port of LSCP server
1704    
1705 schoenebeck 579 Version 0.3.1 (24 May 2005)
1706    
1707     * initial release
