Added NKSP test cases for core built-in variables.

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 3550
42 schoenebeck 3551 * Real-time instrument scripts:
43     - Added method ScriptVM::setExitResultEnabled() which allows to
44     explicitly enable the built-in exit() function to optionally accept
45     one function argument; the value of the passed exit() function
46     argument will then become available by calling
47     VMExecContext::exitResult() after script execution.
48 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
49 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
50     with a regular character (a-z or A-Z); starting them with a digit or
51     underscore is not allowed.
52     - NKSP parser fix: equal comparison operator "=" and not equal comparison
53     operator "#" must only accept integer operands.
54     - NKSP language: Implemented support for standard units like Hertz, seconds,
55     Bel including support for metric unit prefixes; so one can now e.g.
56     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
57     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
58     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
59     - NKSP language: Introduced "final" operator "!" which is specifically
60     intended for synthesis parameter values to denote that the synthesis
61     parameter value is intended to be the "final" value for that synthesis
62     parameter that should explicitly be used by the engine and thus causing
63     the sampler engine to ignore all other modulation sources for the same
64     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
65     variable or formula with this new "!" operator the expression is marked as
66     being "final".
67 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
68     and their potential metric prefix token.
69 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
70     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
71     - NKSP language: Added support for NKSP real number (floating point) script
72     variables (declare ~foo).
73     - NKSP language: Added support for NKSP real number (floating point) array
74     script variables (declare ?foo[]).
75     - Built-in script function "message()" accepts now real number argument as
76     well.
77     - Added built-in script function "real_to_int()" and its short hand form
78     "int()" for casting from real number to integer in NKSP scripts.
79     - Added built-in script function "int_to_real()" and its short hand form
80     "real()" for casting from integer to real number in NKSP scripts.
81 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
82     argument as well.
83 schoenebeck 3577 - Built-in script functions may have a different return type depending on
84     the arguments passed to the function.
85     - Built-in script function "abs()" optionally accepts and returns real
86     number.
87     - Built-in script functions "min()" and "max()" optionally accept real
88     number arguments and return real number as result in that case.
89 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
90     built-in functions (added methods VMFunction::returnUnitType() and
91     VMFunction::returnsFinal() for that purpose which must be implemented by
92     built-in function implementations).
93     - NKSP language: Allow metric unit prefixes of numeric scalar and array
94     variables to be changed freely at runtime (unlike unit types like Hz etc.
95     which are still sticky, parse-time features of variables which cannot be
96     changed at runtime for the intentional sake of determinism).
97     - NKSP language: 'final' values are prohibited for array variables for now
98     (attempt causes a parsers error).
99     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
100     conditions of runtime control structures like if(), while(), select()
101     (attempt causes a parser error).
102     - NKSP VM API: Allow built-in functions to perform their own, individual
103     parse time checks of arguments going to be passed to the function at
104     runtime (added method VMFunction::checkArgs() for that purpose).
105     - NKSP language: raise parser warning if only one operand of binary
106     operators (like logical 'or' comparison) contain a 'final' value (because
107     it would always yield in a 'final' result in such cases).
108     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
109     different metric unit prefixes, which will behave as expected (e.g.
110     result of expression '1000us < 2ms' is true).
111     - NKSP language: Allow adding values with different metric unit prefixes
112     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
113     - NKSP language: Allow subtracting values with different metric unit
114     prefixes (e.g. result of expression '1ms - 20us' is '980us').
115     - NKSP language: Allow multiplying with any metric unit prefixes
116     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
117     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
118     we don't have any considerable practical use for a term like '4s^2'
119     (hence any attempt multiplying two unit types still causes parser error).
120     - NKSP language: Allow dividing by any metric unit prefixes and allow
121     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
122     yields in unit free result '8'). So this is now a way to cast units away
123     e.g. for passing the result to other expressions, certain function calls
124     or variables which are not accepting any units (or that specific unit).
125     - NKSP language: integer arrays and real number arrays can now be converted
126     to strings (e.g. for dumping their content with message() calls for
127     script debugging purposes).
128     - NKSP language: expressions and variables with units are now correctly
129     casted to strings (e.g. with message() calls).
130     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
131     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
132     floating point tolerances into account.
133     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
134     VMScalarNumberExpr::evalCastReal().
135     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
136     'VMIntArrayExpr' and 'VMRealArrayExpr'.
137     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
138     unitFactor() (runtime) methods.
139     - Built-in function "exit()" supports now returning units and 'final'ness
140     for test cases.
141     - The following built-in functions support now units as well: "abs()",
142     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
143     "real_to_int()", "int()", "int_to_real()" and "real()".
144     - Built-in functions "array_equal()", "search()" and "sort()" support now
145     real number arrays (correctly) as well.
146     - Added individual parse time checks of arguments to be passed to built-in
147     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
148     "array_equal()" and "search()" specific for their individual purposes.
149 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
150     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
151     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
152     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
153     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
154     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
155     isScalarNumber() -> isNumber()).
156 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
157     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
158     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
159     as convenient methods for automatically converting values to expected
160     metric value basis.
161     - Built-in function "wait()" accepts now both integers and real numbers as
162     argument.
163 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
164     VMFunction::argType(vmint iArg) which was already superseded by its new
165     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
166     - NKSP parser: if wrong argument type was passed to a built-in function and
167     that built-in function accepts more than one data type for the argument,
168     then show all supported data types as parser error message.
169 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
170     unit type as well for its 3rd and 4th function arguments.
171     - The following built-in functions accept now real numbers as well for their
172     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
173     "change_attack()", "change_decay()", "change_release()",
174     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
175     "change_cutoff_sustain()", "change_cutoff_release()",
176     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
178     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
179     - Fixed built-in function "change_play_pos()" not having accepted metric
180     prefixes at all.
181 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
182     with unit type (for their 2nd argument) as if they were relative values
183     (that is as if they were passed without a unit type): "change_attack()",
184     "change_decay()", "change_release()", "change_cutoff_attack()",
185     "change_cutoff_decay()", "change_cutoff_release()".
186     - Fixed the following built-in functions having applied completely wrong
187     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
188     respective EGs being their modulation sink assume uint data type with
189     value range 0..1000 instead of 0.0..1.0.
190     - Added individual parse-time checks of function arguments for the following
191     built-in functions: "play_note()", "note_off()", "set_event_mark()",
192     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
193     "change_decay()", "change_release()", "change_cutoff_attack()",
194     "change_cutoff_decay()", "change_cutoff_release()",
195     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
196     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
197     "change_pan_time()".
198     - Don't abort function call if unit type was used and at the same time
199     'final' operator was omitted for the primary value argument of the
200     following built-in functions: "change_cutoff()", "change_attack()",
201     "change_decay()", "change_release()", "change_cutoff_attack()",
202     "change_cutoff_decay()", "change_cutoff_release()",
203     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
204     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
205     "change_pan_time()", instead imply 'final'ness at runtime and raise an
206     appropriate parser warning at parse time.
207 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
208     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
209     "cos()", "tan()", "asin()", "acos()", "atan()".
210     - Added built-in script real number constant "~NI_MATH_PI".
211     - Added built-in script real number constant "~NI_MATH_E".
212 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
213 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
214 schoenebeck 3690 - NKSP language: Added support for RPN event handler
215     ("on rpn ... end on" in instrument scripts).
216     - NKSP language: Added support for NRPN event handler
217     ("on nrpn ... end on" in instrument scripts).
218     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
219     may be read from the new RPN/NRPN script handlers to get the (N)RPN
220     parameter that had been changed and its new value.
221     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
222     which are identifying the new (N)RPN handlers as such at script runtime.
223 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
224     - Implemented built-in script function "set_nrpn()".
225 schoenebeck 3551
226 schoenebeck 3550 * test cases:
227 schoenebeck 3548 - Fixed compiler errors in test cases.
228     - Updated README for how to compile & run test cases.
229     - Updated test case
230     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
231     expected behaviour of the Mutex class implementation (recursive
232     mutex type).
233 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
234     functions.
235 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
236 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
237     int_to_real(), real(), real_to_int() and int(), as well as for the
238     plus, minus and negate language operators.
239 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
240     'final' operator usage cases.
241     - Added NKSP test cases for (floating point tolerance aware) real number
242     equalness / unequalness comparison.
243 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
244     initialization of arrays.
245 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
246     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
247     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
248 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
249 schoenebeck 3693 - Added NKSP test cases for core built-in variables.
250 schoenebeck 3548
251 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
252     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
253     behaviour for start_level_mid.
254 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
255     level (see discussion "GigaStudio LFO compatibility" on mailing list
256     from 2019-09-26 for details).
257 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
258     see discussion "GigaStudio LFO compatibility" on mailing list from
259     2019-09-26 for details).
260 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
261     either sine [default], triangle, saw or square).
262     - Format extension: Added support for LFO phase displacement (0��..360��).
263     - Format extension: Added support for flipping LFO polarity on LFO 3
264     (in the original gig format this was only available for LFO 1 and LFO 2).
265 schoenebeck 3646 - Format extension: Support for additional filter types:
266     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
267     bandreject 2-pole.
268 schoenebeck 3611
269 persson 3593 * SFZ format engine:
270     - Fixed support for regions with loccN/hiccN conditions on more than one
271     MIDI controller.
272    
273 schoenebeck 3612 * Benchmarks:
274     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
275     algorithm (since result of 2nd run was not accumulated).
276     - Added benchmark for saw wave (benchmarks/saw.cpp).
277     - Added benchmark for sine wave (benchmarks/sine.cpp).
278     - Added benchmark for square wave (benchmarks/square.cpp).
279     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
280     which are large enough on modern systems.
281    
282 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
283 schoenebeck 3381
284     * Real-time instrument scripts:
285     - Fixed behavior of built-in NKSP functions change_sustain(),
286     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
287     and change_cutoff_release().
288    
289 schoenebeck 3444 * general changes:
290     - Only play release trigger samples on sustain pedal up if this behaviour
291     was explicitly requested by the instrument (otherwise only on note-off).
292 persson 3455 - Fixed compiler warnings.
293     - Fixed compilation error when cross-compiling to Mac.
294 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
295     (see bug #169).
296     - LSCP doc: Be more clear describing the two distinct approaches
297     of using external vs. internal effects (see bug #169).
298 schoenebeck 3514 - "optional" class: Fixed comparison operators.
299 schoenebeck 3444
300 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
301     - Format extension: If requested by instrument then don't play release
302     trigger sample on note-off events.
303    
304 schoenebeck 3487 * SFZ format engine:
305     - Fixed memory leak when releasing samples
306     (fixes bug #307, patch by Jacek Roszkowski)
307 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
308     (fixes bug #308, patch by Jacek Roszkowski).
309 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
310     (fixes bug #310, patch by Jacek Roszkowski).
311 schoenebeck 3487
312 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
313 persson 2837
314 persson 2856 * SFZ format engine:
315     - added support for <global>, <master> and #define (patch by Alby M)
316 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
317     - Added support for sfz extension opcode 'script' which may be used to
318     load real-time instrument script file (NKSP script language).
319 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
320 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
321 persson 3291 - sfz parser: allow missing space between header and opcode
322 persson 2856
323 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
324 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
325     cutoff settings.
326 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
327     all if an up-pitch of more than 40 semi tones was requested (I don't
328     think there is any stock gig sound that requires this behavior to
329     resemble its original sound).
330 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
331     be aborted (as LinuxSampler extension to the original GigaStudio 4
332     format).
333 schoenebeck 3072
334 persson 2837 * general changes:
335     - fixed printf type errors (mostly in debug messages)
336 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
337 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
338     allowing to sort data efficiently in real-time safe manner.
339     - RTList class: added methods for moving/inserting elements to arbitrary
340     position within a list.
341     - RTList class: added method fromPtr() for creating an Iterator object from
342     a raw element pointer.
343     - Attempt to partly fix resetting engine channels vs. resetting engine, an
344     overall cleanup of the Reset*(), ConnectAudioDevice(),
345     DisconnectAudioDevice() API methods would still be desirable though,
346     because the current situation is still inconsistent and error prone.
347 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
348     being directly assigned to a keyboard key. This allows more fine graded
349     processing of voices, which is i.e. required for certain instrument
350     script features.
351 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
352     (CC #64) events.
353     - Fix: Release trigger voices can now also distinguish correctly between
354     note-off and sustain pedal up events.
355 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
356     (while slow rate of crossfade smoother is preserved) to allow quick
357     volume and pan changes by instrument scripts for instance.
358 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
359     properly and thus were ignored for certain uses.
360 schoenebeck 3018 - Added new C++ API method
361     VirtualMidiDevice::SendChannelPressureToSampler().
362 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
363     sub threads is 16-byte aligned
364 schoenebeck 3054 - fixed numerous compiler warnings
365 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
366 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
367     fixes potential undefined behavior.
368 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
369     have a valid sample mapped (fixes bug #252).
370     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
371 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
372     subsequent optional argument due to glibc's implementation oddity
373     which expects a "=" sign, but no space between them.
374 persson 2837
375 schoenebeck 2866 * packaging changes:
376     - removed unnecessary dependency to libuuid
377     (originated by libgig's usage of it)
378 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
379     auto detect whether it (sh/c)ould output its messages in color.
380 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
381     substitution variable.

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

418     - Implemented built-in script function "change_reso()".
419     - Implemented built-in script function "event_status()".
420     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
421     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
422     "event_status()" function.
423     - NKSP language: Added support for bitwise operators ".or.", ".and."
424     and ".not.".
425     - NKSP language scanner: Fixed IDs matching to require at least one
426     character (i.e. when matching function names or variable names).
427     - NKSP language scanner: disabled unusued rules.
428 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
429     be distinguished engine internally from "real" MIDI note on/off
430     events in order to avoid misbehaviors like hanging notes.
431 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
432     - Implemented built-in script variable "$NKSP_REAL_TIMER".
433     - Implemented built-in script variable "$NKSP_PERF_TIMER".

436     - Implemented built-in script function "dec()".
437     - NKSP language fix: division expressions were evaluated too often.
438     - NKSP language fix: string concatenation operator was right
439     associative instead of left (to right).
440 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
441     (i.e. "if end if").
442 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
443     - Implemented built-in script variable "$NI_CALLBACK_ID".
444     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
445     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

449     - Added built-in script constant "$NI_CB_TYPE_NOTE".
450     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

454     - Implemented built-in script function "change_decay()".
455     - Implemented built-in script function "change_release()".
456 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
457     synthesis parameter changes immediately in case the respective note
458     was triggered at the same time, instead of scheduling the parameter
459     change, especially because it would cause some parameter types's
460     changes either to be ramped (i.e. change_vol()) or other types even
461     to have not effect at all (i.e. change_attack()).
462 schoenebeck 2965 - Implemented built-in script function "sh_left()".
463     - Implemented built-in script function "sh_right()".
464 schoenebeck 2970 - Implemented built-in script function "min()".

466 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
467     was loaded.
468     - NKSP built-in wait() script function: abort script execution if
469     a negative or zero wait time was passed as argument (since this is
470     a common indication of a bug either of the script or even of the
471     engine, which could lead to RT instability or even worse).
472 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
473     threatening scripts.
474 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
475 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
476     initializer list to an array variable.
477 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
478 schoenebeck 3076 - Implemented built-in script function "in_range()".

482     - Implemented built-in script function "change_pitch_lfo_freq()".
483 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
484     - Implemented built-in script function "change_tune_time()".
485     - Implemented built-in script function "fade_in()".
486     - Implemented built-in script function "fade_out()".
487     - Fixed acceptance of wrong data type of parameters passed to built-in
488     script functions "change_vol()", "change_tune()", "change_pan()",
489     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
490     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
491     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
492 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
493     of its possible parameter selections.
494     - Added built-in script function "set_event_par()" and implemented some
495     of its possible parameter selections.
496 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
497 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
498 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
499     built-in function "ignore_controller()".
500 schoenebeck 3214 - Implemented built-in script function "change_velo()".
501     - Implemented built-in script function "change_note()".
502 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
503     intuitive behavior if used in combination with "change_vol_time()" or
504     "change_tune_time()" respectively: now tuning/volume changes are only
505     assigned (without delay) immediately to a new note if the respective
506     timing function has not been called before, otherwise the volume/tuning
507     changes are automatically faded (before, only the event's time stamp was
508     relevant).
509 schoenebeck 3221 - Implemented built-in script function "array_equal()".
510     - Implemented built-in script function "search()".
511     - Implemented built-in script function "sort()".
512     - NKSP Fix: Never suspend "init" event handlers.
513 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
514     available for gig format engine).
515 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
516     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
517     - Implemented built-in script function "change_vol_curve()".
518     - Implemented built-in script function "change_tune_curve()".
519 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
520     offset with argument 3, where special value -1 means to use the regular
521     sample offset as defined by the instrument file.
522 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
523     - Built-in variable $EVENT_NOTE is now a read-only variable.
524     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
525     - built-in "play_note()" function now accepts -2 for its fourth argument
526     (note duration) which means the life time of the note shall be sticked
527     to the requested note number of argument 1.
528     - Fix: built-in "play_note()" function now returns 0 as result value if
529     -1 was passed for its fourth argument (note duration) and the respective
530     parent note is already gone.
531 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
532 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
533     - NKSP language: Raise parser warning if array variable is accessed with
534     an index that exceeds the array's size.
535 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
536 schoenebeck 3260 - NKSP language: Added support for "synchronized .. end synchronized"
537     code blocks.
538 schoenebeck 3277 - Implemented built-in script function "abort()" which allows to abort
539     another script handler by passing its callback ID.
540 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
541     "init" event handlers.
542 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
543     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
544     to retrieve all code blocks filtered out by the preprocessor.
545 schoenebeck 3293 - Added built-in script function "fork()".
546     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
547     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
548     - Fixed potential crash when accessing dynamic built-in array variables.
549 schoenebeck 3296 - Added built-in script function "callback_status()".
550     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
551     - Added built-in constant $CALLBACK_STATUS_QUEUE.
552     - Added built-in constant $CALLBACK_STATUS_RUNNING.
553 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
554     "change_decay()" and "change_release()" to i.e. allow passing 2000000
555     for doubling the respective time.
556 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
557     to a lexer start condition stack underrun.
558     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
559     USE_CODE_IF_NOT() preprocessor statements.
560 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
561     can be set to disable all subsequent built-in "message()" function calls
562     on preprocessor level.
563 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
564 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
565     to avoid the editor app to crash on ill-formed text input.
566 schoenebeck 3335 - Added built-in script function "change_pan_time()".
567     - Added built-in script function "change_pan_curve()".
568 schoenebeck 3360 - Added built-in script function "change_cutoff_attack()".
569     - Added built-in script function "change_cutoff_decay()".
570     - Added built-in script function "change_cutoff_sustain()".
571     - Added built-in script function "change_cutoff_release()".
572     - Added built-in script function "change_cutoff_lfo_depth()".
573     - Added built-in script function "change_cutoff_lfo_freq()".
574 schoenebeck 2871
575 schoenebeck 3050 * Instruments DB:
576     - Fixed memory access bug of general DB access code which lead to
577     undefined behavior.
578 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
579     - The instrument DB path of linuxsampler's --create-instruments-db argument
580     is now optional, if it is missing, then a default location is used.
581 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
582     - Added support for scanning Sound Font (.sf2) files.
583 schoenebeck 3101 - Fixed undefined DB transaction behavior.
584 schoenebeck 3050
585 schoenebeck 2787 Version 2.0.0 (15 July 2015)
586 schoenebeck 1993
587 persson 2086 * packaging changes:

589 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
590     - Mac OS X: fixed building outside source directory
591     - made sure all source files for hostplugins are included when
592     doing "make dist"
593     - removed empty directories left from the cvs to svn migration
594 persson 2185 - fixed compilation with gcc 4.6.1
595 persson 2203 - another "make dist" fix, for the LV2 plugin
596 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
597 persson 2197 - minor Makefile fix for building lscpparser when build and source
598     directories are separate
599 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
600     configure
601 persson 2208 - Mac OS X: Makefile fix for the install-strip target
602 persson 2335 - fixed compilation with gcc 4.7

605     gcc 4.7 and C++11
606 persson 2365 - modernized configure script
607 persson 2378 - fixed linkage error when building with
608     LDFLAGS="-Wl,--no-undefined" (#190)
609 persson 2390 - fixed compilation with Clang 3.2
610 persson 2420 - removed usage of deprecated Automake variable INCLUDES

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

1091     after MIDI/audio device creation failure
1092 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1094     took the full preloading time and on 1st program change the respective
1095     instrument was completely reloaded again.
1096 persson 2277 - fixed handling of rapid bank select and program change messages
1097     sent to the same sampler channel (patch from the Open Octave

1119     (fixes #208)
1120 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1121     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1122     practically irrelevant, however it caused problems with the new LSCP
1123     shell's auto completion feature).
1124 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1125     after each other (fixes #231).

1177     stacktrace mechanism seems to be broken on most systems at the moment)
1178 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1179     a pointer to the launched InstrumentEditor object
1180 schoenebeck 1876 - added optional 3rd party user data parameter for following

1204 persson 1888 - applied old fixes to the ASIO driver that were included in the
1205     previous binary release but accidentally never committed to CVS
1206     (fixes #117)

1244     instrument database compilable
1245 schoenebeck 1930 - added instrument database support on Windows
1246     works with both standalone mode and VST plugin.
1247     the instruments DB file is located in
1248     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1249     databases for each windows user
1250     if no DB is present it automatically creates the .linuxsampler subdir
1251     and then creates an empty DB
1252 persson 1943 - fixed recursive import, which was broken on Windows
1253 iliev 1603
1254 persson 1644 * Gigasampler format engine:
1255     - fixed a memory leak that could happen when a channel was deleted
1256     while notes were playing
1257 persson 1646 - made it possible to load an instrument even if the audio thread
1258     isn't running
1259 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,

1262     respective FX send MIDI controller was used
1263 schoenebeck 1724 - added support for GM global device volume SysEx message
1264 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1265     whole sampler [default] or only to the sampler channels that are
1266     connected to the respective MIDI input port the SysEx message arrived
1267     on)
1268 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1269     sometimes wrongly killed in the same buffer, causing no sound to
1270     be played
1271 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1272     which is usally used to switch a part between chromatic sounds and
1273     drumkit sounds (as opposed to their common default setting of MIDI
1274     part 10 being a drumkit part and all other ones chromatic parts), in
1275     LS however one can switch between the first 16 MIDI instrument maps
1276     defined for the sampler
1277 persson 1764 - made it possible to create multiple sample channels even if the
1278     audio thread isn't running
1279 persson 1844 - fixed crash when removing channel with active voices (#116)
1280 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1281     un-cache the respective sample if it's really not used by any
1282     sampler engine anymore
1283     - re-cache samples in case they were changed by an instrument editor,
1284     e.g. when a sample was added while playing (#82)
1285 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1286     same time stamp as the voice's note-on event and occured both in the
1287     same audio fragment cycle (fixes bug #112)
1288 persson 1858 - added support for the "fine tune" and "pitch bend range"
1289     instrument-level gig parameters
1290     - fixed minor artifacts in pitch bend handling
1291 schoenebeck 1860 - added support for GS Reset SysEx message
1292 persson 1862 - allow gig files to use unlimited downward pitch shifting
1293     - added a limit check for upward pitch shifting
1294 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1295     note was silent
1296 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1297     same time a new instrument was loading
1298 persson 1644
1299 schoenebeck 1687 * LSCP server:
1300     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1301     react on MIDI data arriving on certain sampler channels (so far only
1302     Note-On and Note-Off events are sent via this LSCP event)
1303 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1304     react on MIDI data arriving on certain MIDI input devices (so far only
1305     Note-On and Note-Off events are sent via this LSCP event)
1306 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1307     SET DB_INSTRUMENT FILE_PATH
1308 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1309     frontends to send MIDI messages to specific sampler channel
1310     - added two additional fields to GET FILE INSTRUMENT INFO command -
1311     KEY_BINDINGS and KEYSWITCH_BINDINGS
1312 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1313     was incorrect
1314 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1315 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1316     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1317     be triggered respectively
1318     - added new LSCP command "SET STREAMS" to globally alter the maximum
1319     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1320     which will be triggered respectively
1321 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1322     a gigedit file dialog is opened)
1323 iliev 1848 - close all connections when LSCPServer is deleted
1324 iliev 1882 - hard close of all sockets on exit

1362 senoner 1502 - added autoconf checks for MS Windows
1363 schoenebeck 1454
1364 persson 1455 * general changes:
1365     - bugfix: the thread used by an editor plugin didn't die when the
1366     editor closed
1367 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1368     out all the space. operator--() did not apply size_mask after
1369     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1370     order to avoid problems with the _NonVolatileReader functions.
1371     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1372     GetWriteSpace(). Since this function is currently only used in
1373     the stream's qsort() compare function, it didn't trigger any
1374     bugs.
1375     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1376     24bit mode too. Faster method to read 24bit words on little
1377     endian machines (x86): replaced 3 byte reads + shifts with a 1
1378     unaligned 32bit read and shift
1379     - experimental support for MS Windows (MIDI input via MME, AUDIO
1380     output via ASIO)
1381     - made handling of SIGINT signal (Ctrl-C) a bit more robust

1391 senoner 1485
1392 schoenebeck 1471 * LSCP server:
1393     - added support for Windows style path / filenames, however with
1394     forward slash path separators instead of backslash
1395     (i.e. "C:/foo/bar.gig")
1396 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1397     apostrophes as well
1398 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1399     "LIST FILE INSTRUMENTS <file>" and
1400     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1401     about an arbitrary instrument file on the system where the sampler is
1402     running on

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