NKSP: Fixed crash with built-in functions returning an array.

* Calling built-in functions returning an array type was broken and
  caused a crash when built-in function's NULL (supposed to be array)
  result value was used by the script VM.

* Bumped version (2.1.1.svn37).

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 3687 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35     *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36     methods and marked the old ones as deprecated; and likewise added new
37     *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38     methods and marked those old ones deprecated as well.
39 schoenebeck 3688 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40     resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41 schoenebeck 3697 - Implemented support for compressed RPN/NRPN message sequences (that is to
42     allow processing MIDI data entry messages without always having to be
43     preceded strictly by RPN/NRPN parameter selection messages on each value
44     change).
45 schoenebeck 3699 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46     decrement).
47 schoenebeck 3701 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48     MSB=127 and LSB=127) and which is disabling subsequent data
49     entry/increment/decrement CC messages.
50 schoenebeck 3550
51 schoenebeck 3551 * Real-time instrument scripts:
52     - Added method ScriptVM::setExitResultEnabled() which allows to
53     explicitly enable the built-in exit() function to optionally accept
54     one function argument; the value of the passed exit() function
55     argument will then become available by calling
56     VMExecContext::exitResult() after script execution.
57 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
58 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
59     with a regular character (a-z or A-Z); starting them with a digit or
60     underscore is not allowed.
61     - NKSP parser fix: equal comparison operator "=" and not equal comparison
62     operator "#" must only accept integer operands.
63     - NKSP language: Implemented support for standard units like Hertz, seconds,
64     Bel including support for metric unit prefixes; so one can now e.g.
65     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
66     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
67     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
68     - NKSP language: Introduced "final" operator "!" which is specifically
69     intended for synthesis parameter values to denote that the synthesis
70     parameter value is intended to be the "final" value for that synthesis
71     parameter that should explicitly be used by the engine and thus causing
72     the sampler engine to ignore all other modulation sources for the same
73     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
74     variable or formula with this new "!" operator the expression is marked as
75     being "final".
76 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
77     and their potential metric prefix token.
78 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
79     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
80     - NKSP language: Added support for NKSP real number (floating point) script
81     variables (declare ~foo).
82     - NKSP language: Added support for NKSP real number (floating point) array
83     script variables (declare ?foo[]).
84     - Built-in script function "message()" accepts now real number argument as
85     well.
86     - Added built-in script function "real_to_int()" and its short hand form
87     "int()" for casting from real number to integer in NKSP scripts.
88     - Added built-in script function "int_to_real()" and its short hand form
89     "real()" for casting from integer to real number in NKSP scripts.
90 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
91     argument as well.
92 schoenebeck 3577 - Built-in script functions may have a different return type depending on
93     the arguments passed to the function.
94     - Built-in script function "abs()" optionally accepts and returns real
95     number.
96     - Built-in script functions "min()" and "max()" optionally accept real
97     number arguments and return real number as result in that case.
98 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
99     built-in functions (added methods VMFunction::returnUnitType() and
100     VMFunction::returnsFinal() for that purpose which must be implemented by
101     built-in function implementations).
102     - NKSP language: Allow metric unit prefixes of numeric scalar and array
103     variables to be changed freely at runtime (unlike unit types like Hz etc.
104     which are still sticky, parse-time features of variables which cannot be
105     changed at runtime for the intentional sake of determinism).
106     - NKSP language: 'final' values are prohibited for array variables for now
107     (attempt causes a parsers error).
108     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
109     conditions of runtime control structures like if(), while(), select()
110     (attempt causes a parser error).
111     - NKSP VM API: Allow built-in functions to perform their own, individual
112     parse time checks of arguments going to be passed to the function at
113     runtime (added method VMFunction::checkArgs() for that purpose).
114     - NKSP language: raise parser warning if only one operand of binary
115     operators (like logical 'or' comparison) contain a 'final' value (because
116     it would always yield in a 'final' result in such cases).
117     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
118     different metric unit prefixes, which will behave as expected (e.g.
119     result of expression '1000us < 2ms' is true).
120     - NKSP language: Allow adding values with different metric unit prefixes
121     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
122     - NKSP language: Allow subtracting values with different metric unit
123     prefixes (e.g. result of expression '1ms - 20us' is '980us').
124     - NKSP language: Allow multiplying with any metric unit prefixes
125     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
126     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
127     we don't have any considerable practical use for a term like '4s^2'
128     (hence any attempt multiplying two unit types still causes parser error).
129     - NKSP language: Allow dividing by any metric unit prefixes and allow
130     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
131     yields in unit free result '8'). So this is now a way to cast units away
132     e.g. for passing the result to other expressions, certain function calls
133     or variables which are not accepting any units (or that specific unit).
134     - NKSP language: integer arrays and real number arrays can now be converted
135     to strings (e.g. for dumping their content with message() calls for
136     script debugging purposes).
137     - NKSP language: expressions and variables with units are now correctly
138     casted to strings (e.g. with message() calls).
139     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
140     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
141     floating point tolerances into account.
142     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
143     VMScalarNumberExpr::evalCastReal().
144     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
145     'VMIntArrayExpr' and 'VMRealArrayExpr'.
146     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
147     unitFactor() (runtime) methods.
148     - Built-in function "exit()" supports now returning units and 'final'ness
149     for test cases.
150     - The following built-in functions support now units as well: "abs()",
151     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
152     "real_to_int()", "int()", "int_to_real()" and "real()".
153     - Built-in functions "array_equal()", "search()" and "sort()" support now
154     real number arrays (correctly) as well.
155     - Added individual parse time checks of arguments to be passed to built-in
156     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
157     "array_equal()" and "search()" specific for their individual purposes.
158 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
159     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
160     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
161     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
162     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
163     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
164     isScalarNumber() -> isNumber()).
165 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
166     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
167     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
168     as convenient methods for automatically converting values to expected
169     metric value basis.
170     - Built-in function "wait()" accepts now both integers and real numbers as
171     argument.
172 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
173     VMFunction::argType(vmint iArg) which was already superseded by its new
174     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
175     - NKSP parser: if wrong argument type was passed to a built-in function and
176     that built-in function accepts more than one data type for the argument,
177     then show all supported data types as parser error message.
178 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
179     unit type as well for its 3rd and 4th function arguments.
180     - The following built-in functions accept now real numbers as well for their
181     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
182     "change_attack()", "change_decay()", "change_release()",
183     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
184     "change_cutoff_sustain()", "change_cutoff_release()",
185     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
187     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
188     - Fixed built-in function "change_play_pos()" not having accepted metric
189     prefixes at all.
190 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
191     with unit type (for their 2nd argument) as if they were relative values
192     (that is as if they were passed without a unit type): "change_attack()",
193     "change_decay()", "change_release()", "change_cutoff_attack()",
194     "change_cutoff_decay()", "change_cutoff_release()".
195     - Fixed the following built-in functions having applied completely wrong
196     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
197     respective EGs being their modulation sink assume uint data type with
198     value range 0..1000 instead of 0.0..1.0.
199     - Added individual parse-time checks of function arguments for the following
200     built-in functions: "play_note()", "note_off()", "set_event_mark()",
201     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
202     "change_decay()", "change_release()", "change_cutoff_attack()",
203     "change_cutoff_decay()", "change_cutoff_release()",
204     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
205     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
206     "change_pan_time()".
207     - Don't abort function call if unit type was used and at the same time
208     'final' operator was omitted for the primary value argument of the
209     following built-in functions: "change_cutoff()", "change_attack()",
210     "change_decay()", "change_release()", "change_cutoff_attack()",
211     "change_cutoff_decay()", "change_cutoff_release()",
212     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
213     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
214     "change_pan_time()", instead imply 'final'ness at runtime and raise an
215     appropriate parser warning at parse time.
216 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
217     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
218     "cos()", "tan()", "asin()", "acos()", "atan()".
219     - Added built-in script real number constant "~NI_MATH_PI".
220     - Added built-in script real number constant "~NI_MATH_E".
221 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
222 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
223 schoenebeck 3690 - NKSP language: Added support for RPN event handler
224     ("on rpn ... end on" in instrument scripts).
225     - NKSP language: Added support for NRPN event handler
226     ("on nrpn ... end on" in instrument scripts).
227     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
228     may be read from the new RPN/NRPN script handlers to get the (N)RPN
229     parameter that had been changed and its new value.
230     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
231     which are identifying the new (N)RPN handlers as such at script runtime.
232 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
233     - Implemented built-in script function "set_nrpn()".
234 schoenebeck 3714 - Fix: built-in functions returning an array type were broken and caused a
235     crash when the built-in function's (supposed to be array) result value was
236     used by the script VM.
237 schoenebeck 3551
238 schoenebeck 3550 * test cases:

240     - Updated README for how to compile & run test cases.
241     - Updated test case
242     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
243     expected behaviour of the Mutex class implementation (recursive
244     mutex type).
245 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
246     functions.
247 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
248 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
249     int_to_real(), real(), real_to_int() and int(), as well as for the
250     plus, minus and negate language operators.
251 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
252     'final' operator usage cases.
253     - Added NKSP test cases for (floating point tolerance aware) real number
254     equalness / unequalness comparison.
255 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
256     initialization of arrays.
257 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
258     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
259     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
260 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.

265     behaviour for start_level_mid.
266 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
267     level (see discussion "GigaStudio LFO compatibility" on mailing list
268     from 2019-09-26 for details).
269 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
270     see discussion "GigaStudio LFO compatibility" on mailing list from
271     2019-09-26 for details).
272 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
273     either sine [default], triangle, saw or square).
274     - Format extension: Added support for LFO phase displacement (0��..360��).
275     - Format extension: Added support for flipping LFO polarity on LFO 3
276     (in the original gig format this was only available for LFO 1 and LFO 2).

278     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
279     bandreject 2-pole.
280 schoenebeck 3611

283     MIDI controller.
284    
285 schoenebeck 3612 * Benchmarks:
286     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"

288     - Added benchmark for saw wave (benchmarks/saw.cpp).
289     - Added benchmark for sine wave (benchmarks/sine.cpp).
290     - Added benchmark for square wave (benchmarks/square.cpp).
291     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
292     which are large enough on modern systems.
293    
294 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
295 schoenebeck 3381
296     * Real-time instrument scripts:
297     - Fixed behavior of built-in NKSP functions change_sustain(),
298     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
299     and change_cutoff_release().
300    
301 schoenebeck 3444 * general changes:
302     - Only play release trigger samples on sustain pedal up if this behaviour
303     was explicitly requested by the instrument (otherwise only on note-off).
304 persson 3455 - Fixed compiler warnings.
305     - Fixed compilation error when cross-compiling to Mac.
306 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
307     (see bug #169).
308     - LSCP doc: Be more clear describing the two distinct approaches
309     of using external vs. internal effects (see bug #169).
310 schoenebeck 3514 - "optional" class: Fixed comparison operators.
311 schoenebeck 3444
312 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
313     - Format extension: If requested by instrument then don't play release
314     trigger sample on note-off events.
315    
316 schoenebeck 3487 * SFZ format engine:
317     - Fixed memory leak when releasing samples
318     (fixes bug #307, patch by Jacek Roszkowski)
319 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
320     (fixes bug #308, patch by Jacek Roszkowski).
321 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
322     (fixes bug #310, patch by Jacek Roszkowski).
323 schoenebeck 3487
324 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
325 persson 2837
326 persson 2856 * SFZ format engine:
327     - added support for <global>, <master> and #define (patch by Alby M)
328 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
329     - Added support for sfz extension opcode 'script' which may be used to
330     load real-time instrument script file (NKSP script language).
331 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
332 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
333 persson 3291 - sfz parser: allow missing space between header and opcode
334 persson 2856
335 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
336 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
337     cutoff settings.
338 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
339     all if an up-pitch of more than 40 semi tones was requested (I don't
340     think there is any stock gig sound that requires this behavior to
341     resemble its original sound).
342 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
343     be aborted (as LinuxSampler extension to the original GigaStudio 4
344     format).
345 schoenebeck 3072
346 persson 2837 * general changes:
347     - fixed printf type errors (mostly in debug messages)
348 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
349 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
350     allowing to sort data efficiently in real-time safe manner.
351     - RTList class: added methods for moving/inserting elements to arbitrary
352     position within a list.
353     - RTList class: added method fromPtr() for creating an Iterator object from
354     a raw element pointer.
355     - Attempt to partly fix resetting engine channels vs. resetting engine, an
356     overall cleanup of the Reset*(), ConnectAudioDevice(),
357     DisconnectAudioDevice() API methods would still be desirable though,
358     because the current situation is still inconsistent and error prone.
359 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
360     being directly assigned to a keyboard key. This allows more fine graded
361     processing of voices, which is i.e. required for certain instrument
362     script features.
363 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
364     (CC #64) events.
365     - Fix: Release trigger voices can now also distinguish correctly between
366     note-off and sustain pedal up events.
367 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
368     (while slow rate of crossfade smoother is preserved) to allow quick
369     volume and pan changes by instrument scripts for instance.
370 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
371     properly and thus were ignored for certain uses.
372 schoenebeck 3018 - Added new C++ API method
373     VirtualMidiDevice::SendChannelPressureToSampler().
374 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
375     sub threads is 16-byte aligned
376 schoenebeck 3054 - fixed numerous compiler warnings
377 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
378 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
379     fixes potential undefined behavior.
380 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
381     have a valid sample mapped (fixes bug #252).
382     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
383 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
384     subsequent optional argument due to glibc's implementation oddity
385     which expects a "=" sign, but no space between them.
386 persson 2837
387 schoenebeck 2866 * packaging changes:
388     - removed unnecessary dependency to libuuid
389     (originated by libgig's usage of it)
390 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
391     auto detect whether it (sh/c)ould output its messages in color.
392 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
393     substitution variable.

396     linuxsampler with instruments DB support.
397 schoenebeck 2866
398 schoenebeck 2871 * Real-time instrument scripts:
399     - Implemented scheduler for delayed MIDI events and for suspended scripts.
400     - Built-in script function "wait()": implemented support for function's
401     "duration-us" argument, thus scripts using this function are now
402     correctly resumed after the requested amount of microseconds.
403     - Built-in script function "play_note()": implemented support for
404     function's "duration-us" argument, thus notes triggered with this
405     argument are now correctly released after the requested amount of
406     microseconds.
407     - Fix: script events were not cleared when engine channel was reset,
408     potentially causing undefined behavior.
409     - Fixed crash which happened when trying to reference an undeclared
410     variable.
411 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
412     special value -1 for "duration-us" argument, which will cause the
413     triggered note to be released once the original note was released.
414 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
415     - Added new API method ScriptVM::syntaxHighlighting() which provides
416     a convenient syntax highlighting backend for external instrument
417     script editor applications.
418 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
419     - Extended parser issues to provide not only first line and first
420     column, but also last line and last column of issue (thus marking
421     the precise span of the issue within the source code).
422 schoenebeck 2902 - Reload script automatically after being modified by an instrument
423     editor.
424 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
425     like "on note end on".
426 schoenebeck 2931 - Implemented built-in script function "change_vol()".
427     - Implemented built-in script function "change_tune()".
428     - Implemented built-in script function "change_pan()".
429 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
430     - Implemented built-in script function "change_reso()".
431     - Implemented built-in script function "event_status()".
432     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
433     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
434     "event_status()" function.
435     - NKSP language: Added support for bitwise operators ".or.", ".and."
436     and ".not.".
437     - NKSP language scanner: Fixed IDs matching to require at least one
438     character (i.e. when matching function names or variable names).
439     - NKSP language scanner: disabled unusued rules.
440 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
441     be distinguished engine internally from "real" MIDI note on/off
442     events in order to avoid misbehaviors like hanging notes.
443 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
444     - Implemented built-in script variable "$NKSP_REAL_TIMER".
445     - Implemented built-in script variable "$NKSP_PERF_TIMER".
446     - Implemented built-in script variable "$ENGINE_UPTIME".
447 schoenebeck 2945 - Implemented built-in script function "inc()".
448     - Implemented built-in script function "dec()".
449     - NKSP language fix: division expressions were evaluated too often.
450     - NKSP language fix: string concatenation operator was right
451     associative instead of left (to right).
452 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
453     (i.e. "if end if").
454 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
455     - Implemented built-in script variable "$NI_CALLBACK_ID".
456     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
457     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
458     - Added support for read-only built-in variables (respectively
459     handled by the script parser).
460     - Added built-in script constant "$NI_CB_TYPE_INIT".
461     - Added built-in script constant "$NI_CB_TYPE_NOTE".
462     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
463     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
464 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
465 schoenebeck 2953 - Implemented built-in script function "change_attack()".
466     - Implemented built-in script function "change_decay()".
467     - Implemented built-in script function "change_release()".
468 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
469     synthesis parameter changes immediately in case the respective note
470     was triggered at the same time, instead of scheduling the parameter
471     change, especially because it would cause some parameter types's
472     changes either to be ramped (i.e. change_vol()) or other types even
473     to have not effect at all (i.e. change_attack()).
474 schoenebeck 2965 - Implemented built-in script function "sh_left()".
475     - Implemented built-in script function "sh_right()".
476 schoenebeck 2970 - Implemented built-in script function "min()".
477     - Implemented built-in script function "max()".
478 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
479     was loaded.
480     - NKSP built-in wait() script function: abort script execution if
481     a negative or zero wait time was passed as argument (since this is
482     a common indication of a bug either of the script or even of the
483     engine, which could lead to RT instability or even worse).
484 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
485     threatening scripts.
486 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
487 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
488     initializer list to an array variable.
489 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
490 schoenebeck 3076 - Implemented built-in script function "in_range()".
491 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".
492     - Implemented built-in script function "change_amp_lfo_freq()".
493     - Implemented built-in script function "change_pitch_lfo_depth()".
494     - Implemented built-in script function "change_pitch_lfo_freq()".
495 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
496     - Implemented built-in script function "change_tune_time()".
497     - Implemented built-in script function "fade_in()".
498     - Implemented built-in script function "fade_out()".
499     - Fixed acceptance of wrong data type of parameters passed to built-in
500     script functions "change_vol()", "change_tune()", "change_pan()",
501     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
502     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
503     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
504 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
505     of its possible parameter selections.
506     - Added built-in script function "set_event_par()" and implemented some
507     of its possible parameter selections.
508 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
509 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
510 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
511     built-in function "ignore_controller()".
512 schoenebeck 3214 - Implemented built-in script function "change_velo()".
513     - Implemented built-in script function "change_note()".
514 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
515     intuitive behavior if used in combination with "change_vol_time()" or
516     "change_tune_time()" respectively: now tuning/volume changes are only
517     assigned (without delay) immediately to a new note if the respective
518     timing function has not been called before, otherwise the volume/tuning
519     changes are automatically faded (before, only the event's time stamp was
520     relevant).
521 schoenebeck 3221 - Implemented built-in script function "array_equal()".
522     - Implemented built-in script function "search()".
523     - Implemented built-in script function "sort()".
524     - NKSP Fix: Never suspend "init" event handlers.
525 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
526     available for gig format engine).
527 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
528     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
529     - Implemented built-in script function "change_vol_curve()".
530     - Implemented built-in script function "change_tune_curve()".
531 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
532     offset with argument 3, where special value -1 means to use the regular
533     sample offset as defined by the instrument file.
534 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
535     - Built-in variable $EVENT_NOTE is now a read-only variable.
536     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
537     - built-in "play_note()" function now accepts -2 for its fourth argument
538     (note duration) which means the life time of the note shall be sticked
539     to the requested note number of argument 1.
540     - Fix: built-in "play_note()" function now returns 0 as result value if
541     -1 was passed for its fourth argument (note duration) and the respective
542     parent note is already gone.
543 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
544 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
545     - NKSP language: Raise parser warning if array variable is accessed with
546     an index that exceeds the array's size.
547 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
548 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
549     code blocks.
550 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
551     another script handler by passing its callback ID.
552 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
553     "init" event handlers.
554 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
555     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
556     to retrieve all code blocks filtered out by the preprocessor.
557 schoenebeck 3293 - Added built-in script function "fork()".
558     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
559     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
560     - Fixed potential crash when accessing dynamic built-in array variables.
561 schoenebeck 3296 - Added built-in script function "callback_status()".
562     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
563     - Added built-in constant $CALLBACK_STATUS_QUEUE.
564     - Added built-in constant $CALLBACK_STATUS_RUNNING.
565 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
566     "change_decay()" and "change_release()" to i.e. allow passing 2000000
567     for doubling the respective time.
568 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
569     to a lexer start condition stack underrun.
570     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
571     USE_CODE_IF_NOT() preprocessor statements.
572 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
573     can be set to disable all subsequent built-in "message()" function calls
574     on preprocessor level.
575 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
576 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
577     to avoid the editor app to crash on ill-formed text input.
578 schoenebeck 3335 - Added built-in script function "change_pan_time()".
579     - Added built-in script function "change_pan_curve()".
580 schoenebeck 3360 - Added built-in script function "change_cutoff_attack()".
581     - Added built-in script function "change_cutoff_decay()".
582     - Added built-in script function "change_cutoff_sustain()".
583     - Added built-in script function "change_cutoff_release()".
584     - Added built-in script function "change_cutoff_lfo_depth()".
585     - Added built-in script function "change_cutoff_lfo_freq()".
586 schoenebeck 2871
587 schoenebeck 3050 * Instruments DB:
588     - Fixed memory access bug of general DB access code which lead to
589     undefined behavior.
590 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
591     - The instrument DB path of linuxsampler's --create-instruments-db argument
592     is now optional, if it is missing, then a default location is used.
593 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
594     - Added support for scanning Sound Font (.sf2) files.
595 schoenebeck 3101 - Fixed undefined DB transaction behavior.
596 schoenebeck 3050
597 schoenebeck 2787 Version 2.0.0 (15 July 2015)
598 schoenebeck 1993
599 persson 2086 * packaging changes:

601 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
602     - Mac OS X: fixed building outside source directory
603     - made sure all source files for hostplugins are included when
604     doing "make dist"
605     - removed empty directories left from the cvs to svn migration
606 persson 2185 - fixed compilation with gcc 4.6.1
607 persson 2203 - another "make dist" fix, for the LV2 plugin
608 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
609 persson 2197 - minor Makefile fix for building lscpparser when build and source
610     directories are separate
611 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
612     configure
613 persson 2208 - Mac OS X: Makefile fix for the install-strip target
614 persson 2335 - fixed compilation with gcc 4.7

616     - lsatomic.h: use gcc provided atomic functions if building with
617     gcc 4.7 and C++11
618 persson 2365 - modernized configure script
619 persson 2378 - fixed linkage error when building with
620     LDFLAGS="-Wl,--no-undefined" (#190)
621 persson 2390 - fixed compilation with Clang 3.2
622 persson 2420 - removed usage of deprecated Automake variable INCLUDES

625     - build fix: libsndfile compiler flags were missing in some
626     makefiles
627 persson 2461 - fix for building with bison 3.0 (#202)
628 schoenebeck 2473 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
629     on the process's main thread
630 persson 2478 - fixed build error on newer MinGW
631     - support building with older jack versions
632     - support building with spaces in vst sdk path
633 persson 2519 - enabled automake 'subdir-objects' option and moved external
634     source references (vst, au, asio) from makefiles to cpp files,
635     in order to get rid of warnings from automake 1.14
636 persson 2382
637 persson 2086 * general changes:
638 iliev 2012 - Refactoring: moved the independent code from
639     the Gigasampler format engine to base classes
640 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
641     respective profiling code is currently broken
642 schoenebeck 2053 - Introduced support for optional environment variable
643     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
644     where the sampler shall look for instrument editor plugins
645     (patch by Luis Garrido, slightly modified).
646 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
647     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
648     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
649     note (in this implementation of the sampler its simply hard routed to
650     the 1st effect send of the sampler channel, no matter what the actual
651     effect type is)
652     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
653     note (in this implementation of the sampler its simply hard routed to
654     the 2nd effect send of the sampler channel, no matter what the actual
655     effect type is)
656 schoenebeck 2124 - implemented support for internal LADSPA effects
657 schoenebeck 2140 - raised limit of program change queue from 100 to 512
658     (as suggested by Alex Stone)
659 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
660 iliev 2296 - experimental support for per voice equalization
661 iliev 2306 - added command line option --exec-after-init
662 schoenebeck 2330 - Introduced new C++ API method:
663     EngineChannel::InstrumentFileName(int index)
664     allowing to retrieve the whole list of files used for the loaded
665     instrument on an engine channel (a.k.a. part). Some GigaStudio
666     instruments for example are splitted over several files like
667     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
668 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
669     - Added new C++ API method Sampler::GetGlobalMaxStreams().
670     - Added new C++ API method Sampler::SetGlobalMaxVoices().
671     - Added new C++ API method Sampler::SetGlobalMaxStreams().
672 schoenebeck 2377 - Various "const" and "restrict" optimizations.
673 persson 2382 - all engines: add pan CC value to instrument pan parameter before
674     applying panning, instead of using two separate pan functions in
675     series (#182)
676 persson 2427 - added a lock guard class for exception safe mutex handling and
677     used it everywhere appropriate
678 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
679     - Exposed scale tuning to C++ API (along to the already existing standard
680     SysEx way).
681 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
682     and broken for ppc64. (Seq_cst loads and stores are actually not
683     used in LS, so the bug wasn't noticable.)
684     - lsatomic.h: added ARMv7 support
685 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
686     added various new C++ methods for this new feature / design change, old
687     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
688     as deprecated but are still there and should provide full behavior
689     backward compatibility).
690     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
691     unsafe and caused compilation error with clang 2.x).
692 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
693 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
694     sampler from the command line by providing LSCP aware features.
695 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
696     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
697     - VirtualMidiDevice: Added support for pitch bend.
698 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
699     polyphonic key pressure events (so far polyphonic pressure was not
700     supported at all, and channel pressure was rerouted as CC128 but not
701     used so far).
702 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
703     code is shared by all sampler engine implemementations, however only the
704     gig file format currently provides support for storing instrument scripts
705     (as LinuxSampler extension to the original GigaStudio 4 format).
706 iliev 2012
707 persson 2043 * Gigasampler format engine:
708     - implemented the "round robin keyboard" dimension
709     - fixed round robin and random dimensions for cases when number of
710     dimension zones is not a power of two
711     - made round robin use a counter for each region instead of each
712     key
713 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
714     - bugfix: filter keyboard tracking was broken
715     - filter performance fix (an unnecessary copy was made of the
716     filter parameters in each sub fragment)
717     - handle special case when pan parameter in gig file has max or

1103     after MIDI/audio device creation failure
1104 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1107     instrument was completely reloaded again.
1108 persson 2277 - fixed handling of rapid bank select and program change messages
1109     sent to the same sampler channel (patch from the Open Octave

1132 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1133     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1134     practically irrelevant, however it caused problems with the new LSCP
1135     shell's auto completion feature).
1136 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1137     after each other (fixes #231).

1189     stacktrace mechanism seems to be broken on most systems at the moment)
1190 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1191     a pointer to the launched InstrumentEditor object
1192 schoenebeck 1876 - added optional 3rd party user data parameter for following

1216 persson 1888 - applied old fixes to the ASIO driver that were included in the
1217     previous binary release but accidentally never committed to CVS
1218     (fixes #117)

1256     instrument database compilable
1257 schoenebeck 1930 - added instrument database support on Windows
1258     works with both standalone mode and VST plugin.
1259     the instruments DB file is located in
1260     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1261     databases for each windows user
1262     if no DB is present it automatically creates the .linuxsampler subdir
1263     and then creates an empty DB
1264 persson 1943 - fixed recursive import, which was broken on Windows
1265 iliev 1603
1266 persson 1644 * Gigasampler format engine:

1275 schoenebeck 1724 - added support for GM global device volume SysEx message
1276 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1277     whole sampler [default] or only to the sampler channels that are
1278     connected to the respective MIDI input port the SysEx message arrived
1279     on)
1280 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1281     sometimes wrongly killed in the same buffer, causing no sound to
1282     be played
1283 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1284     which is usally used to switch a part between chromatic sounds and
1285     drumkit sounds (as opposed to their common default setting of MIDI
1286     part 10 being a drumkit part and all other ones chromatic parts), in
1287     LS however one can switch between the first 16 MIDI instrument maps
1288     defined for the sampler
1289 persson 1764 - made it possible to create multiple sample channels even if the
1290     audio thread isn't running
1291 persson 1844 - fixed crash when removing channel with active voices (#116)
1292 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1293     un-cache the respective sample if it's really not used by any
1294     sampler engine anymore
1295     - re-cache samples in case they were changed by an instrument editor,
1296     e.g. when a sample was added while playing (#82)
1297 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1298     same time stamp as the voice's note-on event and occured both in the
1299     same audio fragment cycle (fixes bug #112)
1300 persson 1858 - added support for the "fine tune" and "pitch bend range"
1301     instrument-level gig parameters
1302     - fixed minor artifacts in pitch bend handling
1303 schoenebeck 1860 - added support for GS Reset SysEx message
1304 persson 1862 - allow gig files to use unlimited downward pitch shifting
1305     - added a limit check for upward pitch shifting
1306 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1307     note was silent
1308 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1309     same time a new instrument was loading
1310 persson 1644
1311 schoenebeck 1687 * LSCP server:
1312     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1313     react on MIDI data arriving on certain sampler channels (so far only
1314     Note-On and Note-Off events are sent via this LSCP event)
1315 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1316     react on MIDI data arriving on certain MIDI input devices (so far only
1317     Note-On and Note-Off events are sent via this LSCP event)
1318 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1319     SET DB_INSTRUMENT FILE_PATH
1320 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1321     frontends to send MIDI messages to specific sampler channel
1322     - added two additional fields to GET FILE INSTRUMENT INFO command -
1323     KEY_BINDINGS and KEYSWITCH_BINDINGS
1324 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1325     was incorrect
1326 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1327 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1328     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1329     be triggered respectively
1330     - added new LSCP command "SET STREAMS" to globally alter the maximum
1331     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1332     which will be triggered respectively
1333 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1334     a gigedit file dialog is opened)
1335 iliev 1848 - close all connections when LSCPServer is deleted
1336 iliev 1882 - hard close of all sockets on exit

1368 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1369 schoenebeck 1454
1370     * packaging changes:
1371     - added autoconf checks for pthread library

1373     glibc versions (see Gentoo bug report #194076)
1374 senoner 1502 - added autoconf checks for MS Windows
1375 schoenebeck 1454
1376 persson 1455 * general changes:
1377     - bugfix: the thread used by an editor plugin didn't die when the
1378     editor closed
1379 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1380     out all the space. operator--() did not apply size_mask after
1381     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1382     order to avoid problems with the _NonVolatileReader functions.
1383     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1384     GetWriteSpace(). Since this function is currently only used in
1385     the stream's qsort() compare function, it didn't trigger any
1386     bugs.
1387     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1388     24bit mode too. Faster method to read 24bit words on little
1389     endian machines (x86): replaced 3 byte reads + shifts with a 1
1390     unaligned 32bit read and shift
1391     - experimental support for MS Windows (MIDI input via MME, AUDIO
1392     output via ASIO)
1393     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1394 iliev 1541 - support for monitoring the total number of active disk streams

1397 persson 1455
1398 senoner 1500 * AUDIO driver:
1399 persson 1534 - added Windows ASIO low latency audio driver
1400 senoner 1500
1401 senoner 1485 * MIDI driver:
1402 schoenebeck 1495 - added MME Windows MIDI driver
1403 senoner 1485
1404 schoenebeck 1471 * LSCP server:
1405     - added support for Windows style path / filenames, however with
1406     forward slash path separators instead of backslash
1407     (i.e. "C:/foo/bar.gig")
1408 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1409     apostrophes as well
1410 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1411     "LIST FILE INSTRUMENTS <file>" and
1412     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1413     about an arbitrary instrument file on the system where the sampler is
1414     running on
1415 schoenebeck 1471
1416 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1417 schoenebeck 947
1418 schoenebeck 1065 * packaging changes:
1419 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1420     API header files anymore
1421 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1422     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1423 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1424     capable to execute our autoconf environment, thus no need anymore
1425     to maintain the compile time configuration file (osx/version.h) for
1426     OSX manually (patch by Toshi Nagata)
1427 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1428     parameters
1429 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1430     C++ API header files, all implementation internal global definitions
1431     are now in global_private.h
1432     - atomic.h is not exposed to the C++ API anymore
1433     - no need to include config.h anymore for using LS's API header files
1434     - fixed warnings in API doc generation
1435 schoenebeck 1065
1436 schoenebeck 947 * general changes:
1437     - replaced the old, confusing MIDI program change mechanism by a
1438     flexible MIDI instrument mapper which allows to map arbitrary
1439 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1440 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1441     loaded on the respective channel when such MIDI program change
1442     messages arrive, beside that, each entry allows to define a life-time
1443     strategy for the instrument, so the user can define whether the
1444     instrument should i.e. be permanently loaded (to be able to switch
1445     quickly among sounds) or i.e. loaded just on demand when the
1446     respective program change arrives (to safe RAM space), as well as a
1447     global volume factor for each entry, so the user can adjust the volume
1448     dynamic of his mapped instrument collection without having to modify
1449 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1450     MIDI instrument maps and assign each sampler channel individually
1451     a certain map, so that i.e. separation of normal instruments and
1452     drumkits is possible
1453 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1454     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1455 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1456     due to a constant size RingBuffer FIFO which is now replaced by a
1457     dynamic (unlimited) size std::list FIFO
1458 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1459     output channels for being processed by external effect processors
1460     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1461     controllers
1462 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1463 iliev 1130 - Implemented new, improved notification system
1464 schoenebeck 1149 - fixed compilation errors regarding OSX
1465     (patch by Toshi Nagata)
1466 iliev 1161 - implemented instruments database
1467 iliev 1345 - added support for escape sequences to the instruments database
1468 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1469     within the sampler's process (by using instrument editor plugins),
1470     you'll notice the new "Registered instrument editors:" message on
1471 schoenebeck 1407 startup, added a new LSCP command:
1472     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1473 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1474     given sampler channel, the plugin path can be overridden at compile
1475     time with ./configure --enable-plugin-dir=/some/dir
1476 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1477     in the sampler's process to safely edit instruments while playing
1478     without a crash (hopefully) by either suspending single regions
1479     wherever possible or if unavoidable whole engine(s)
1480 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1481     policy and priority on thread level, set a minimum stack size for
1482     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1483     threads simply inherited properties of starting thread instead of
1484     setting their own policy and priority
1485 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1486     main process did not wait for the stack trace process to finish
1487     its output
1488 persson 1248 - fixed some minor memory leaks
1489 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1490     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1491 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1492     register, to avoid relocations in the text segment at runtime)
1493 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1494 schoenebeck 947
1495     * MIDI driver:
1496     - dispatch bank select (MSB and LSB) messages
1497    
1498 schoenebeck 1049 * audio driver:
1499     - the ALSA audio output driver parameters now reflect the correct
1500     parameter value ranges for the respective selected sound card
1501     (patch by Till Wimmer, a bit fixed and extended)
1502    
1503 persson 951 * Gigasampler format engine:
1504     - if a filter is used and EG2 finishes before EG1, let the voice
1505     die when EG2 has finished (this fixes a problem with clicks and
1506     voice starvation for some gigs)
1507 persson 1038 - playback is no longer disabled during instrument loading
1508     - all notes playing on a channel that changes its instrument keep
1509     playing with the old instrument until they get a note off
1510     command
1511 persson 1039 - EG fix: a release value of zero could cause noises or crash
1512 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1513 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1514     above max sustain level, which means that there is a decay phase
1515     even if sustain is 100%
1516 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1517     noises or crashes
1518 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1519 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1520     supplied to the configure script (fixes #46)
1521 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1522     instead of a fix value
1523 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1524     127 (solo mode) only kill voices if the respective mode really
1525     changed
1526 persson 951
1527 schoenebeck 1244 * LSCP server:
1528     - fixed compile time error for old Bison versions
1529     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1530 schoenebeck 1245 - parser now supports extended ASCII character set
1531     (up to ASCII code 255, i.e. includes now umlauts and accents)
1532     - filename arguments in LSCP commands now allow to use escape
1533     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1534     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1535     code value like \xf2) (fixes bug #24)
1536 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1537     least one of their text-based parameters (i.e. name, description):
1538     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1539     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1540     "SET DB_INSTRUMENT_DIRECTORY NAME",
1541     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1542     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1543     "FIND DB_INSTRUMENT_DIRECTORIES"
1544 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1545     occured, the unexpected character and the actually expected, possible
1546     character(s), the latter only if less than 5 possibilities)
1547 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1548     settings
1549 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1550     of strings were treated as being one string containing commas
1551     (fixes #57)
1552 schoenebeck 1244
1553 iliev 959 * Bug fixes:
1554     - fixed crash occurring on certain LSCP scripts (Bug 39)
1555 persson 1038 - another thread safety fix for lscp "load engine" and "set
1556     channel audio output device"
1557 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1558     on a sampler channel with connected MIDI device
1559 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1560     device connected to a sampler channel to number less then or equal
1561     to the index of the port to which the sampler channel is connected.
1562 iliev 1296 - The previous bindings were not been disconnected when altering
1563     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1564     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1565 iliev 1297 - The active stream/voice count statistic was incorrect.
1566 iliev 1298 - notification events were not been sent for some sampler
1567     channel changes
1568 iliev 1305 - added default min and max values to restrict the number of allowed
1569     audio output channels and MIDI input ports
1570 iliev 1306 - the connection to the PCM interface is now closed when destroying
1571     an audio output device
1572 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1573 iliev 959
1574 schoenebeck 1221 * test cases:
1575     - updated and fixed (haven't been touched in a while)
1576    
1577 schoenebeck 937 Version 0.4.0 (24 November 2006)
1578 persson 696
1579 schoenebeck 697 * packaging changes:
1580 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1581     to post-(un)install steps; added devel package for liblinuxsampler;
1582     to linuxsampler.spec (RPM)
1583 schoenebeck 697 - install necessary development header files for allowing 3rd party
1584     applications to link against liblinuxsampler
1585     - liblinuxsampler's API documentation can be generated with 'make docs'
1586     (Doxygen required)
1587 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1588     implementation (currently either an integer math solution or a
1589     di-harmonic approximation), automatic detection can be overriden
1590     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1591     configure script argument though (mandatory for cross-compilation)
1592 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1593     provided some on his own (as CXXFLAGS)
1594 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1595     messages
1596 schoenebeck 852 - added compile time options to allow disabling the various audio and
1597     MIDI drivers
1598 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1599     (patch by Ebrahim Mayat)
1600 schoenebeck 697
1601 persson 696 * Gigasampler format engine:
1602 schoenebeck 738 - extensive synthesis optimization
1603     (reimplementation of EGs and LFO(s), removed synthesis parameter
1604     prerendering and the synthesis parameter matrix in general, splitting
1605     each audio fragment into subfragments now where each subfragment uses
1606 persson 830 constant pitch and filter coefficients. The volume coefficient is
1607     linearly interpolated inside a subfragment, unless
1608     --disable-interpolate-volume is set.)
1609 persson 696 - fine tuning of the EG modulation parameters
1610 persson 729 - improved filter cutoff calculation by adding support for the
1611     following gig parameters: Cutoff freq (used when no cutoff
1612     controller is defined), Control invert, Minimum cutoff, Velocity
1613 persson 791 curve and Velocity range. The keyboard tracking now scales
1614     cutoff frequency instead of resonance.
1615 persson 877 - added support for gig parameter Resonance.
1616 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1617 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1618     which can be overridden with --enable-global-attenuation
1619 persson 783 - EG fixes: made the length of "attack hold" stage more
1620     accurate. Release stage can now start before attack stage
1621 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1622     time now has a minimal value to prevent clicks.
1623 persson 799 - fixed pitch changes larger than one octave
1624 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1625     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1626     all modes can be altered via standard GM messages, that is CC5 for
1627     altering portamento time, CC65 for enabling / disabling portamento
1628     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1629 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1630     parameter) and crossfade
1631 persson 831 - added support for the "attenuation controller threshold" gig
1632     parameter
1633 persson 832 - added smoothing of volume changes caused by control change
1634     messages
1635 persson 865 - sample loop parameters are now taken from the DimensionRegion
1636     instead of the wave chunk
1637     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1638     not equal to a power of two
1639 persson 877 - reimplementation of the filter algorithm. The new filter is more
1640     accurate and supports all gig filter types, including bandreject
1641     and lowpass turbo.
1642 persson 903 - real support for 24 bit samples - samples are not truncated to
1643     16 bits anymore
1644     - support for aftertouch (channel pressure, not polyphonic
1645     aftertouch)
1646 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1647     amplifying from 0)
1648 persson 696
1649 schoenebeck 711 * LSCP server:
1650     - fixed application exit on broken pipe error (fixes bug #20)
1651 iliev 793 - fixed the notification messages delay due to lack of
1652     network activity (fixes bug #26)
1653 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1654     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1655 schoenebeck 711
1656 schoenebeck 838 * audio driver:
1657     - added aRts audio output driver (by no means RT safe)
1658    
1659 schoenebeck 775 * MIDI driver:
1660     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1661     messages several times instead of once
1662 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1663     for events (i.e. for offline rendering based MIDI drivers)
1664 persson 922 - added checks for bad MIDI data
1665 schoenebeck 775
1666 schoenebeck 900 * linuxsampler application:
1667     - show available sampler engine types on startup
1668    
1669 schoenebeck 705 * general changes:
1670     - support for muting sampler channels and solo mode of the same, two new
1671     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1672     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1673     introduced for this, the behavior is the same like on a mixer console
1674 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1675     --enable-process-muted-channels which can be used to enable the
1676     processing of muted channels.
1677 iliev 777 - support for sostenuto pedal
1678 iliev 779 - support for monitoring the total number of active voices
1679 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1680     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1681 persson 835 - fixed some memory management errors
1682 persson 841 - fixed some concurrency problems that could lead to crashes when
1683     LSCP commands were executed
1684 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1685     sampler channel (fixes bug #36)
1686 schoenebeck 705
1687 schoenebeck 692 Version 0.3.3 (15 July 2005)
1688 schoenebeck 686
1689     * packaging changes:
1690     - fixed compilation with gcc 4.0
1691    
1692 schoenebeck 687 * Gigasampler format engine:
1693     - LFO preprocessing was performed even though the respective LFO was
1694     disabled by the instrument patch (minor efficiency fix)
1695 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1696     for volume ramp downs in the same fragment (needed for current voice
1697     stealing implementation) then simply inform the user with a warning
1698     about possible click sounds and reduce the volume ramp down
1699     appropriately instead of cancelling the audio device connection
1700 schoenebeck 687
1701 schoenebeck 677 Version 0.3.2 (24 June 2005)
1702 schoenebeck 609
1703     * packaging changes:
1704     - updated autotools build files to compile on OS X
1705     (conditional compilation of CoreMIDI and MidiShare drivers)
1706 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1707     './configure --disable-asm' (definitely not recommended)
1708 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1709     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1710     (due to 'dist-bzip2' automake option)
1711 schoenebeck 649
1712     * Gigasampler format engine:
1713     - support for the gig parameters for "release velocity response" curves
1714     - fine tuning of the EGADSR envelope
1715     - volume of release triggered samples now depends on note-on velocity,
1716     note length and gig parameter "release trigger decay" instead of
1717     note-off velocity.
1718 schoenebeck 663 - revised voice stealing
1719     (fixes crash and endless loop caused by voice stealing)
1720 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1721 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1722     instead of when the respective voice is actually launched
1723     (fixes undefined behavior if stolen voices belonged to a key group -
1724     this case was followed by a "killed voice survived" error message)
1725 schoenebeck 669 - fixed minor issue with null/silence samples
1726     (those stole voices even though they don't need a voice at all which
1727     resulted in "voice stealing didn't work out" messages)
1728 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1729     instrument or audio output device change
1730 schoenebeck 654
1731 schoenebeck 620 * LSCP server:
1732 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1733 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1734 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1735 schoenebeck 609
1736 schoenebeck 668 * linuxsampler application:
1737     - added command line parameters --lscp-addr and --lscp-port to override
1738     default IP address and port of LSCP server
1739    
1740 schoenebeck 579 Version 0.3.1 (24 May 2005)
1741    
1742     * initial release
