* Fixed playing noise at the end of a disk stream under certain
  conditions.

* Bumped version (2.1.1.svn42).

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 3724 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51     instrument editor.
52 schoenebeck 3725 - Fixed playing noise at the end of a disk stream under certain conditions.
53 schoenebeck 3550
54 schoenebeck 3551 * Real-time instrument scripts:
55     - Added method ScriptVM::setExitResultEnabled() which allows to
56     explicitly enable the built-in exit() function to optionally accept
57     one function argument; the value of the passed exit() function
58     argument will then become available by calling
59     VMExecContext::exitResult() after script execution.
60 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
61 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
62     with a regular character (a-z or A-Z); starting them with a digit or
63     underscore is not allowed.
64     - NKSP parser fix: equal comparison operator "=" and not equal comparison
65     operator "#" must only accept integer operands.
66     - NKSP language: Implemented support for standard units like Hertz, seconds,
67     Bel including support for metric unit prefixes; so one can now e.g.
68     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
69     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
70     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
71     - NKSP language: Introduced "final" operator "!" which is specifically
72     intended for synthesis parameter values to denote that the synthesis
73     parameter value is intended to be the "final" value for that synthesis
74     parameter that should explicitly be used by the engine and thus causing
75     the sampler engine to ignore all other modulation sources for the same
76     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
77     variable or formula with this new "!" operator the expression is marked as
78     being "final".
79 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
80     and their potential metric prefix token.
81 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
82     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
83     - NKSP language: Added support for NKSP real number (floating point) script
84     variables (declare ~foo).
85     - NKSP language: Added support for NKSP real number (floating point) array
86     script variables (declare ?foo[]).
87     - Built-in script function "message()" accepts now real number argument as
88     well.
89     - Added built-in script function "real_to_int()" and its short hand form
90     "int()" for casting from real number to integer in NKSP scripts.
91     - Added built-in script function "int_to_real()" and its short hand form
92     "real()" for casting from integer to real number in NKSP scripts.
93 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
94     argument as well.
95 schoenebeck 3577 - Built-in script functions may have a different return type depending on
96     the arguments passed to the function.
97     - Built-in script function "abs()" optionally accepts and returns real
98     number.
99     - Built-in script functions "min()" and "max()" optionally accept real
100     number arguments and return real number as result in that case.
101 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
102     built-in functions (added methods VMFunction::returnUnitType() and
103     VMFunction::returnsFinal() for that purpose which must be implemented by
104     built-in function implementations).
105     - NKSP language: Allow metric unit prefixes of numeric scalar and array
106     variables to be changed freely at runtime (unlike unit types like Hz etc.
107     which are still sticky, parse-time features of variables which cannot be
108     changed at runtime for the intentional sake of determinism).
109     - NKSP language: 'final' values are prohibited for array variables for now
110     (attempt causes a parsers error).
111     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
112     conditions of runtime control structures like if(), while(), select()
113     (attempt causes a parser error).
114     - NKSP VM API: Allow built-in functions to perform their own, individual
115     parse time checks of arguments going to be passed to the function at
116     runtime (added method VMFunction::checkArgs() for that purpose).
117     - NKSP language: raise parser warning if only one operand of binary
118     operators (like logical 'or' comparison) contain a 'final' value (because
119     it would always yield in a 'final' result in such cases).
120     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
121     different metric unit prefixes, which will behave as expected (e.g.
122     result of expression '1000us < 2ms' is true).
123     - NKSP language: Allow adding values with different metric unit prefixes
124     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
125     - NKSP language: Allow subtracting values with different metric unit
126     prefixes (e.g. result of expression '1ms - 20us' is '980us').
127     - NKSP language: Allow multiplying with any metric unit prefixes
128     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
129     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
130     we don't have any considerable practical use for a term like '4s^2'
131     (hence any attempt multiplying two unit types still causes parser error).
132     - NKSP language: Allow dividing by any metric unit prefixes and allow
133     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
134     yields in unit free result '8'). So this is now a way to cast units away
135     e.g. for passing the result to other expressions, certain function calls
136     or variables which are not accepting any units (or that specific unit).
137     - NKSP language: integer arrays and real number arrays can now be converted
138     to strings (e.g. for dumping their content with message() calls for
139     script debugging purposes).
140     - NKSP language: expressions and variables with units are now correctly
141     casted to strings (e.g. with message() calls).
142     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
143     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
144     floating point tolerances into account.
145     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
146     VMScalarNumberExpr::evalCastReal().
147     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
148     'VMIntArrayExpr' and 'VMRealArrayExpr'.
149     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
150     unitFactor() (runtime) methods.
151     - Built-in function "exit()" supports now returning units and 'final'ness
152     for test cases.
153     - The following built-in functions support now units as well: "abs()",
154     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
155     "real_to_int()", "int()", "int_to_real()" and "real()".
156     - Built-in functions "array_equal()", "search()" and "sort()" support now
157     real number arrays (correctly) as well.
158     - Added individual parse time checks of arguments to be passed to built-in
159     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
160     "array_equal()" and "search()" specific for their individual purposes.
161 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
162     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
163     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
164     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
165     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
166     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
167     isScalarNumber() -> isNumber()).
168 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
169     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
170     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
171     as convenient methods for automatically converting values to expected
172     metric value basis.
173     - Built-in function "wait()" accepts now both integers and real numbers as
174     argument.
175 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
176     VMFunction::argType(vmint iArg) which was already superseded by its new
177     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
178     - NKSP parser: if wrong argument type was passed to a built-in function and
179     that built-in function accepts more than one data type for the argument,
180     then show all supported data types as parser error message.
181 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
182     unit type as well for its 3rd and 4th function arguments.
183     - The following built-in functions accept now real numbers as well for their
184     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
185     "change_attack()", "change_decay()", "change_release()",
186     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
187     "change_cutoff_sustain()", "change_cutoff_release()",
188     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
189     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
190     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
191     - Fixed built-in function "change_play_pos()" not having accepted metric
192     prefixes at all.
193 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
194     with unit type (for their 2nd argument) as if they were relative values
195     (that is as if they were passed without a unit type): "change_attack()",
196     "change_decay()", "change_release()", "change_cutoff_attack()",
197     "change_cutoff_decay()", "change_cutoff_release()".
198     - Fixed the following built-in functions having applied completely wrong
199     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
200     respective EGs being their modulation sink assume uint data type with
201     value range 0..1000 instead of 0.0..1.0.
202     - Added individual parse-time checks of function arguments for the following
203     built-in functions: "play_note()", "note_off()", "set_event_mark()",
204     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
205     "change_decay()", "change_release()", "change_cutoff_attack()",
206     "change_cutoff_decay()", "change_cutoff_release()",
207     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
208     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
209     "change_pan_time()".
210     - Don't abort function call if unit type was used and at the same time
211     'final' operator was omitted for the primary value argument of the
212     following built-in functions: "change_cutoff()", "change_attack()",
213     "change_decay()", "change_release()", "change_cutoff_attack()",
214     "change_cutoff_decay()", "change_cutoff_release()",
215     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
216     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
217     "change_pan_time()", instead imply 'final'ness at runtime and raise an
218     appropriate parser warning at parse time.
219 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
220     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
221     "cos()", "tan()", "asin()", "acos()", "atan()".
222     - Added built-in script real number constant "~NI_MATH_PI".
223     - Added built-in script real number constant "~NI_MATH_E".
224 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
225 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
226 schoenebeck 3690 - NKSP language: Added support for RPN event handler
227     ("on rpn ... end on" in instrument scripts).
228     - NKSP language: Added support for NRPN event handler
229     ("on nrpn ... end on" in instrument scripts).
230     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
231     may be read from the new RPN/NRPN script handlers to get the (N)RPN
232     parameter that had been changed and its new value.
233     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
234     which are identifying the new (N)RPN handlers as such at script runtime.
235 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
236     - Implemented built-in script function "set_nrpn()".
237 schoenebeck 3714 - Fix: built-in functions returning an array type were broken and caused a
238     crash when the built-in function's (supposed to be array) result value was
239     used by the script VM.
240 schoenebeck 3715 - Removed upper value constraint for 2nd argument of built-in functions
241     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
242     "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
243     "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
244     "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
245     the LFO frequency / resonance / cutoff frequency.
246 schoenebeck 3551
247 schoenebeck 3550 * test cases:

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

271 schoenebeck 3548
272 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
273     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
274     behaviour for start_level_mid.
275 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
276     level (see discussion "GigaStudio LFO compatibility" on mailing list
277     from 2019-09-26 for details).
278 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
279     see discussion "GigaStudio LFO compatibility" on mailing list from
280     2019-09-26 for details).
281 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
282     either sine [default], triangle, saw or square).
283     - Format extension: Added support for LFO phase displacement (0��..360��).
284     - Format extension: Added support for flipping LFO polarity on LFO 3
285     (in the original gig format this was only available for LFO 1 and LFO 2).
286 schoenebeck 3646 - Format extension: Support for additional filter types:
287     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
288     bandreject 2-pole.
289 schoenebeck 3719 - Fixd potential crash with polynomial interpolator and max. pitch.
290 schoenebeck 3721 - If minimum cutoff is defined, remap cutoff controller CC values to really
291     span the entire possible cutoff range (and avoiding a dead controller
292     zone).
293 schoenebeck 3611
294 persson 3593 * SFZ format engine:
295     - Fixed support for regions with loccN/hiccN conditions on more than one
296     MIDI controller.
297    
298 schoenebeck 3612 * Benchmarks:
299     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
300     algorithm (since result of 2nd run was not accumulated).
301     - Added benchmark for saw wave (benchmarks/saw.cpp).
302     - Added benchmark for sine wave (benchmarks/sine.cpp).
303     - Added benchmark for square wave (benchmarks/square.cpp).
304     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
305     which are large enough on modern systems.
306    
307 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
308 schoenebeck 3381
309     * Real-time instrument scripts:
310     - Fixed behavior of built-in NKSP functions change_sustain(),
311     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
312     and change_cutoff_release().
313    
314 schoenebeck 3444 * general changes:
315     - Only play release trigger samples on sustain pedal up if this behaviour
316     was explicitly requested by the instrument (otherwise only on note-off).
317 persson 3455 - Fixed compiler warnings.
318     - Fixed compilation error when cross-compiling to Mac.
319 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
320     (see bug #169).
321     - LSCP doc: Be more clear describing the two distinct approaches
322     of using external vs. internal effects (see bug #169).
323 schoenebeck 3514 - "optional" class: Fixed comparison operators.
324 schoenebeck 3444
325 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
326     - Format extension: If requested by instrument then don't play release
327     trigger sample on note-off events.
328    
329 schoenebeck 3487 * SFZ format engine:
330     - Fixed memory leak when releasing samples
331     (fixes bug #307, patch by Jacek Roszkowski)
332 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
333     (fixes bug #308, patch by Jacek Roszkowski).

350     cutoff settings.
351 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
352     all if an up-pitch of more than 40 semi tones was requested (I don't
353     think there is any stock gig sound that requires this behavior to
354     resemble its original sound).
355 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
356     be aborted (as LinuxSampler extension to the original GigaStudio 4
357     format).
358 schoenebeck 3072
359 persson 2837 * general changes:
360     - fixed printf type errors (mostly in debug messages)
361 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
362 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
363     allowing to sort data efficiently in real-time safe manner.
364     - RTList class: added methods for moving/inserting elements to arbitrary
365     position within a list.
366     - RTList class: added method fromPtr() for creating an Iterator object from
367     a raw element pointer.
368     - Attempt to partly fix resetting engine channels vs. resetting engine, an
369     overall cleanup of the Reset*(), ConnectAudioDevice(),
370     DisconnectAudioDevice() API methods would still be desirable though,
371     because the current situation is still inconsistent and error prone.
372 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
373     being directly assigned to a keyboard key. This allows more fine graded
374     processing of voices, which is i.e. required for certain instrument
375     script features.
376 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
377     (CC #64) events.
378     - Fix: Release trigger voices can now also distinguish correctly between
379     note-off and sustain pedal up events.
380 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
381     (while slow rate of crossfade smoother is preserved) to allow quick
382     volume and pan changes by instrument scripts for instance.
383 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
384     properly and thus were ignored for certain uses.
385 schoenebeck 3018 - Added new C++ API method
386     VirtualMidiDevice::SendChannelPressureToSampler().
387 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
388     sub threads is 16-byte aligned
389 schoenebeck 3054 - fixed numerous compiler warnings
390 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
391 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
392     fixes potential undefined behavior.
393 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
394     have a valid sample mapped (fixes bug #252).
395     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
396 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
397     subsequent optional argument due to glibc's implementation oddity
398     which expects a "=" sign, but no space between them.
399 persson 2837
400 schoenebeck 2866 * packaging changes:
401     - removed unnecessary dependency to libuuid
402     (originated by libgig's usage of it)
403 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
404     auto detect whether it (sh/c)ould output its messages in color.
405 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
406     substitution variable.
407     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
408 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
409     linuxsampler with instruments DB support.
410 schoenebeck 2866
411 schoenebeck 2871 * Real-time instrument scripts:
412     - Implemented scheduler for delayed MIDI events and for suspended scripts.
413     - Built-in script function "wait()": implemented support for function's
414     "duration-us" argument, thus scripts using this function are now
415     correctly resumed after the requested amount of microseconds.
416     - Built-in script function "play_note()": implemented support for
417     function's "duration-us" argument, thus notes triggered with this
418     argument are now correctly released after the requested amount of
419     microseconds.
420     - Fix: script events were not cleared when engine channel was reset,
421     potentially causing undefined behavior.
422     - Fixed crash which happened when trying to reference an undeclared
423     variable.
424 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
425     special value -1 for "duration-us" argument, which will cause the
426     triggered note to be released once the original note was released.
427 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
428     - Added new API method ScriptVM::syntaxHighlighting() which provides
429     a convenient syntax highlighting backend for external instrument
430     script editor applications.
431 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
432     - Extended parser issues to provide not only first line and first
433     column, but also last line and last column of issue (thus marking
434     the precise span of the issue within the source code).
435 schoenebeck 2902 - Reload script automatically after being modified by an instrument
436     editor.
437 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
438     like "on note end on".
439 schoenebeck 2931 - Implemented built-in script function "change_vol()".
440     - Implemented built-in script function "change_tune()".
441     - Implemented built-in script function "change_pan()".
442 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
443     - Implemented built-in script function "change_reso()".
444     - Implemented built-in script function "event_status()".
445     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
446     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
447     "event_status()" function.
448     - NKSP language: Added support for bitwise operators ".or.", ".and."
449     and ".not.".
450     - NKSP language scanner: Fixed IDs matching to require at least one
451     character (i.e. when matching function names or variable names).
452     - NKSP language scanner: disabled unusued rules.
453 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
454     be distinguished engine internally from "real" MIDI note on/off
455     events in order to avoid misbehaviors like hanging notes.
456 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
457     - Implemented built-in script variable "$NKSP_REAL_TIMER".
458     - Implemented built-in script variable "$NKSP_PERF_TIMER".
459     - Implemented built-in script variable "$ENGINE_UPTIME".
460 schoenebeck 2945 - Implemented built-in script function "inc()".
461     - Implemented built-in script function "dec()".
462     - NKSP language fix: division expressions were evaluated too often.
463     - NKSP language fix: string concatenation operator was right
464     associative instead of left (to right).
465 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
466     (i.e. "if end if").
467 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
468     - Implemented built-in script variable "$NI_CALLBACK_ID".
469     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
470     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
471     - Added support for read-only built-in variables (respectively

474     - Added built-in script constant "$NI_CB_TYPE_NOTE".
475     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

479     - Implemented built-in script function "change_decay()".
480     - Implemented built-in script function "change_release()".
481 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
482     synthesis parameter changes immediately in case the respective note
483     was triggered at the same time, instead of scheduling the parameter
484     change, especially because it would cause some parameter types's
485     changes either to be ramped (i.e. change_vol()) or other types even
486     to have not effect at all (i.e. change_attack()).
487 schoenebeck 2965 - Implemented built-in script function "sh_left()".
488     - Implemented built-in script function "sh_right()".
489 schoenebeck 2970 - Implemented built-in script function "min()".
490     - Implemented built-in script function "max()".
491 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
492     was loaded.
493     - NKSP built-in wait() script function: abort script execution if
494     a negative or zero wait time was passed as argument (since this is
495     a common indication of a bug either of the script or even of the
496     engine, which could lead to RT instability or even worse).
497 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
498     threatening scripts.
499 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
500 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
501     initializer list to an array variable.
502 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
503 schoenebeck 3076 - Implemented built-in script function "in_range()".

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

613     - fixed building with newer MinGW-w64
614 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
615     - Mac OS X: fixed building outside source directory

617     doing "make dist"
618     - removed empty directories left from the cvs to svn migration
619 persson 2185 - fixed compilation with gcc 4.6.1
620 persson 2203 - another "make dist" fix, for the LV2 plugin
621 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
622 persson 2197 - minor Makefile fix for building lscpparser when build and source
623     directories are separate
624 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
625     configure

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

1120     instrument was completely reloaded again.
1121 persson 2277 - fixed handling of rapid bank select and program change messages

1145 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1146     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1147     practically irrelevant, however it caused problems with the new LSCP
1148     shell's auto completion feature).
1149 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1150     after each other (fixes #231).

1202     stacktrace mechanism seems to be broken on most systems at the moment)
1203 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1204     a pointer to the launched InstrumentEditor object
1205 schoenebeck 1876 - added optional 3rd party user data parameter for following

1271     works with both standalone mode and VST plugin.
1272     the instruments DB file is located in
1273     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1274     databases for each windows user
1275     if no DB is present it automatically creates the .linuxsampler subdir
1276     and then creates an empty DB
1277 persson 1943 - fixed recursive import, which was broken on Windows
1278 iliev 1603
1279 persson 1644 * Gigasampler format engine:

1291     connected to the respective MIDI input port the SysEx message arrived
1292     on)
1293 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1294     sometimes wrongly killed in the same buffer, causing no sound to
1295     be played
1296 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1297     which is usally used to switch a part between chromatic sounds and
1298     drumkit sounds (as opposed to their common default setting of MIDI
1299     part 10 being a drumkit part and all other ones chromatic parts), in
1300     LS however one can switch between the first 16 MIDI instrument maps
1301     defined for the sampler
1302 persson 1764 - made it possible to create multiple sample channels even if the
1303     audio thread isn't running
1304 persson 1844 - fixed crash when removing channel with active voices (#116)

1306     un-cache the respective sample if it's really not used by any
1307     sampler engine anymore
1308     - re-cache samples in case they were changed by an instrument editor,
1309     e.g. when a sample was added while playing (#82)
1310 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1311     same time stamp as the voice's note-on event and occured both in the
1312     same audio fragment cycle (fixes bug #112)
1313 persson 1858 - added support for the "fine tune" and "pitch bend range"
1314     instrument-level gig parameters
1315     - fixed minor artifacts in pitch bend handling
1316 schoenebeck 1860 - added support for GS Reset SysEx message
1317 persson 1862 - allow gig files to use unlimited downward pitch shifting
1318     - added a limit check for upward pitch shifting
1319 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1320     note was silent
1321 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1322     same time a new instrument was loading
1323 persson 1644
1324 schoenebeck 1687 * LSCP server:
1325     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1326     react on MIDI data arriving on certain sampler channels (so far only
1327     Note-On and Note-Off events are sent via this LSCP event)
1328 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1329     react on MIDI data arriving on certain MIDI input devices (so far only
1330     Note-On and Note-Off events are sent via this LSCP event)
1331 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1332     SET DB_INSTRUMENT FILE_PATH
1333 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1334     frontends to send MIDI messages to specific sampler channel
1335     - added two additional fields to GET FILE INSTRUMENT INFO command -
1336     KEY_BINDINGS and KEYSWITCH_BINDINGS
1337 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1338     was incorrect
1339 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1340 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1341     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1342     be triggered respectively
1343     - added new LSCP command "SET STREAMS" to globally alter the maximum
1344     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1345     which will be triggered respectively
1346 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1347     a gigedit file dialog is opened)

1388 schoenebeck 1454
1389 persson 1455 * general changes:
1390     - bugfix: the thread used by an editor plugin didn't die when the
1391     editor closed
1392 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1393     out all the space. operator--() did not apply size_mask after

1395     order to avoid problems with the _NonVolatileReader functions.
1396     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1397     GetWriteSpace(). Since this function is currently only used in
1398     the stream's qsort() compare function, it didn't trigger any
1399     bugs.
1400     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1401     24bit mode too. Faster method to read 24bit words on little
1402     endian machines (x86): replaced 3 byte reads + shifts with a 1
1403     unaligned 32bit read and shift
1404     - experimental support for MS Windows (MIDI input via MME, AUDIO
1405     output via ASIO)
1406     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1407 iliev 1541 - support for monitoring the total number of active disk streams
1408     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1409     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1410 persson 1455
1411 senoner 1500 * AUDIO driver:
1412 persson 1534 - added Windows ASIO low latency audio driver
1413 senoner 1500
1414 senoner 1485 * MIDI driver:
1415 schoenebeck 1495 - added MME Windows MIDI driver
1416 senoner 1485
1417 schoenebeck 1471 * LSCP server:
1418     - added support for Windows style path / filenames, however with
1419     forward slash path separators instead of backslash
1420     (i.e. "C:/foo/bar.gig")
1421 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1422     apostrophes as well
1423 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1424     "LIST FILE INSTRUMENTS <file>" and
1425     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1426     about an arbitrary instrument file on the system where the sampler is
1427     running on
1428 schoenebeck 1471
1429 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1430 schoenebeck 947
1431 schoenebeck 1065 * packaging changes:
1432 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1433     API header files anymore
1434 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1435     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1436 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1437     capable to execute our autoconf environment, thus no need anymore
1438     to maintain the compile time configuration file (osx/version.h) for
1439     OSX manually (patch by Toshi Nagata)
1440 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1441     parameters
1442 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1443     C++ API header files, all implementation internal global definitions
1444     are now in global_private.h
1445     - atomic.h is not exposed to the C++ API anymore
1446     - no need to include config.h anymore for using LS's API header files
1447     - fixed warnings in API doc generation
1448 schoenebeck 1065
1449 schoenebeck 947 * general changes:
1450     - replaced the old, confusing MIDI program change mechanism by a
1451     flexible MIDI instrument mapper which allows to map arbitrary
1452 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1453 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1454     loaded on the respective channel when such MIDI program change
1455     messages arrive, beside that, each entry allows to define a life-time
1456     strategy for the instrument, so the user can define whether the
1457     instrument should i.e. be permanently loaded (to be able to switch
1458     quickly among sounds) or i.e. loaded just on demand when the
1459     respective program change arrives (to safe RAM space), as well as a
1460     global volume factor for each entry, so the user can adjust the volume
1461     dynamic of his mapped instrument collection without having to modify
1462 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1463     MIDI instrument maps and assign each sampler channel individually
1464     a certain map, so that i.e. separation of normal instruments and
1465     drumkits is possible
1466 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1467     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1468 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1469     due to a constant size RingBuffer FIFO which is now replaced by a
1470     dynamic (unlimited) size std::list FIFO
1471 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1472     output channels for being processed by external effect processors
1473     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1474     controllers
1475 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1476 iliev 1130 - Implemented new, improved notification system
1477 schoenebeck 1149 - fixed compilation errors regarding OSX
1478     (patch by Toshi Nagata)
1479 iliev 1161 - implemented instruments database
1480 iliev 1345 - added support for escape sequences to the instruments database
1481 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1482     within the sampler's process (by using instrument editor plugins),
1483     you'll notice the new "Registered instrument editors:" message on
1484 schoenebeck 1407 startup, added a new LSCP command:
1485     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1486 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1487     given sampler channel, the plugin path can be overridden at compile
1488     time with ./configure --enable-plugin-dir=/some/dir
1489 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1490     in the sampler's process to safely edit instruments while playing
1491     without a crash (hopefully) by either suspending single regions
1492     wherever possible or if unavoidable whole engine(s)
1493 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1494     policy and priority on thread level, set a minimum stack size for
1495     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1496     threads simply inherited properties of starting thread instead of
1497     setting their own policy and priority
1498 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1499     main process did not wait for the stack trace process to finish
1500     its output
1501 persson 1248 - fixed some minor memory leaks
1502 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1503     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1504 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1505     register, to avoid relocations in the text segment at runtime)
1506 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1507 schoenebeck 947
1508     * MIDI driver:
1509     - dispatch bank select (MSB and LSB) messages
1510    
1511 schoenebeck 1049 * audio driver:
1512     - the ALSA audio output driver parameters now reflect the correct
1513     parameter value ranges for the respective selected sound card
1514     (patch by Till Wimmer, a bit fixed and extended)
1515    
1516 persson 951 * Gigasampler format engine:
1517     - if a filter is used and EG2 finishes before EG1, let the voice
1518     die when EG2 has finished (this fixes a problem with clicks and
1519     voice starvation for some gigs)
1520 persson 1038 - playback is no longer disabled during instrument loading
1521     - all notes playing on a channel that changes its instrument keep
1522     playing with the old instrument until they get a note off
1523     command
1524 persson 1039 - EG fix: a release value of zero could cause noises or crash
1525 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1526 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1527     above max sustain level, which means that there is a decay phase
1528     even if sustain is 100%
1529 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1530     noises or crashes
1531 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1532 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1533     supplied to the configure script (fixes #46)
1534 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1535     instead of a fix value
1536 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1537     127 (solo mode) only kill voices if the respective mode really
1538     changed
1539 persson 951
1540 schoenebeck 1244 * LSCP server:
1541     - fixed compile time error for old Bison versions
1542     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1543 schoenebeck 1245 - parser now supports extended ASCII character set
1544     (up to ASCII code 255, i.e. includes now umlauts and accents)
1545     - filename arguments in LSCP commands now allow to use escape
1546     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1547     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1548     code value like \xf2) (fixes bug #24)
1549 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1550     least one of their text-based parameters (i.e. name, description):
1551     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1552     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1553     "SET DB_INSTRUMENT_DIRECTORY NAME",
1554     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1555     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1556     "FIND DB_INSTRUMENT_DIRECTORIES"
1557 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1558     occured, the unexpected character and the actually expected, possible
1559     character(s), the latter only if less than 5 possibilities)
1560 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1561     settings
1562 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1563     of strings were treated as being one string containing commas
1564     (fixes #57)
1565 schoenebeck 1244
1566 iliev 959 * Bug fixes:
1567     - fixed crash occurring on certain LSCP scripts (Bug 39)
1568 persson 1038 - another thread safety fix for lscp "load engine" and "set
1569     channel audio output device"
1570 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1571     on a sampler channel with connected MIDI device
1572 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1573     device connected to a sampler channel to number less then or equal
1574     to the index of the port to which the sampler channel is connected.
1575 iliev 1296 - The previous bindings were not been disconnected when altering
1576     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1577     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1578 iliev 1297 - The active stream/voice count statistic was incorrect.
1579 iliev 1298 - notification events were not been sent for some sampler
1580     channel changes
1581 iliev 1305 - added default min and max values to restrict the number of allowed
1582     audio output channels and MIDI input ports
1583 iliev 1306 - the connection to the PCM interface is now closed when destroying
1584     an audio output device
1585 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1586 iliev 959
1587 schoenebeck 1221 * test cases:
1588     - updated and fixed (haven't been touched in a while)
1589    
1590 schoenebeck 937 Version 0.4.0 (24 November 2006)
1591 persson 696
1592 schoenebeck 697 * packaging changes:
1593 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1594     to post-(un)install steps; added devel package for liblinuxsampler;
1595     to linuxsampler.spec (RPM)
1596 schoenebeck 697 - install necessary development header files for allowing 3rd party
1597     applications to link against liblinuxsampler
1598     - liblinuxsampler's API documentation can be generated with 'make docs'
1599     (Doxygen required)
1600 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1601     implementation (currently either an integer math solution or a
1602     di-harmonic approximation), automatic detection can be overriden
1603     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1604     configure script argument though (mandatory for cross-compilation)
1605 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1606     provided some on his own (as CXXFLAGS)
1607 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1608     messages
1609 schoenebeck 852 - added compile time options to allow disabling the various audio and
1610     MIDI drivers
1611 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1612     (patch by Ebrahim Mayat)
1613 schoenebeck 697
1614 persson 696 * Gigasampler format engine:
1615 schoenebeck 738 - extensive synthesis optimization
1616     (reimplementation of EGs and LFO(s), removed synthesis parameter
1617     prerendering and the synthesis parameter matrix in general, splitting
1618     each audio fragment into subfragments now where each subfragment uses
1619 persson 830 constant pitch and filter coefficients. The volume coefficient is
1620     linearly interpolated inside a subfragment, unless
1621     --disable-interpolate-volume is set.)
1622 persson 696 - fine tuning of the EG modulation parameters
1623 persson 729 - improved filter cutoff calculation by adding support for the
1624     following gig parameters: Cutoff freq (used when no cutoff
1625     controller is defined), Control invert, Minimum cutoff, Velocity
1626 persson 791 curve and Velocity range. The keyboard tracking now scales
1627     cutoff frequency instead of resonance.
1628 persson 877 - added support for gig parameter Resonance.
1629 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1630 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1631     which can be overridden with --enable-global-attenuation
1632 persson 783 - EG fixes: made the length of "attack hold" stage more
1633     accurate. Release stage can now start before attack stage
1634 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1635     time now has a minimal value to prevent clicks.
1636 persson 799 - fixed pitch changes larger than one octave
1637 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1638     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1639     all modes can be altered via standard GM messages, that is CC5 for
1640     altering portamento time, CC65 for enabling / disabling portamento
1641     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1642 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1643     parameter) and crossfade
1644 persson 831 - added support for the "attenuation controller threshold" gig
1645     parameter
1646 persson 832 - added smoothing of volume changes caused by control change
1647     messages
1648 persson 865 - sample loop parameters are now taken from the DimensionRegion
1649     instead of the wave chunk
1650     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1651     not equal to a power of two
1652 persson 877 - reimplementation of the filter algorithm. The new filter is more
1653     accurate and supports all gig filter types, including bandreject
1654     and lowpass turbo.
1655 persson 903 - real support for 24 bit samples - samples are not truncated to
1656     16 bits anymore
1657     - support for aftertouch (channel pressure, not polyphonic
1658     aftertouch)
1659 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1660     amplifying from 0)
1661 persson 696
1662 schoenebeck 711 * LSCP server:
1663     - fixed application exit on broken pipe error (fixes bug #20)
1664 iliev 793 - fixed the notification messages delay due to lack of
1665     network activity (fixes bug #26)
1666 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1667     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1668 schoenebeck 711
1669 schoenebeck 838 * audio driver:
1670     - added aRts audio output driver (by no means RT safe)
1671    
1672 schoenebeck 775 * MIDI driver:
1673     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1674     messages several times instead of once
1675 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1676     for events (i.e. for offline rendering based MIDI drivers)
1677 persson 922 - added checks for bad MIDI data
1678 schoenebeck 775
1679 schoenebeck 900 * linuxsampler application:
1680     - show available sampler engine types on startup
1681    
1682 schoenebeck 705 * general changes:
1683     - support for muting sampler channels and solo mode of the same, two new
1684     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1685     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1686     introduced for this, the behavior is the same like on a mixer console
1687 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1688     --enable-process-muted-channels which can be used to enable the
1689     processing of muted channels.
1690 iliev 777 - support for sostenuto pedal
1691 iliev 779 - support for monitoring the total number of active voices
1692 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1693     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1694 persson 835 - fixed some memory management errors
1695 persson 841 - fixed some concurrency problems that could lead to crashes when
1696     LSCP commands were executed
1697 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1698     sampler channel (fixes bug #36)
1699 schoenebeck 705
1700 schoenebeck 692 Version 0.3.3 (15 July 2005)
1701 schoenebeck 686
1702     * packaging changes:
1703     - fixed compilation with gcc 4.0
1704    
1705 schoenebeck 687 * Gigasampler format engine:
1706     - LFO preprocessing was performed even though the respective LFO was
1707     disabled by the instrument patch (minor efficiency fix)
1708 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1709     for volume ramp downs in the same fragment (needed for current voice
1710     stealing implementation) then simply inform the user with a warning
1711     about possible click sounds and reduce the volume ramp down
1712     appropriately instead of cancelling the audio device connection
1713 schoenebeck 687
1714 schoenebeck 677 Version 0.3.2 (24 June 2005)
1715 schoenebeck 609
1716     * packaging changes:
1717     - updated autotools build files to compile on OS X
1718     (conditional compilation of CoreMIDI and MidiShare drivers)
1719 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1720     './configure --disable-asm' (definitely not recommended)
1721 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1722     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1723     (due to 'dist-bzip2' automake option)
1724 schoenebeck 649
1725     * Gigasampler format engine:
1726     - support for the gig parameters for "release velocity response" curves
1727     - fine tuning of the EGADSR envelope
1728     - volume of release triggered samples now depends on note-on velocity,
1729     note length and gig parameter "release trigger decay" instead of
1730     note-off velocity.
1731 schoenebeck 663 - revised voice stealing
1732     (fixes crash and endless loop caused by voice stealing)
1733 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1734 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1735     instead of when the respective voice is actually launched
1736     (fixes undefined behavior if stolen voices belonged to a key group -
1737     this case was followed by a "killed voice survived" error message)
1738 schoenebeck 669 - fixed minor issue with null/silence samples
1739     (those stole voices even though they don't need a voice at all which
1740     resulted in "voice stealing didn't work out" messages)
1741 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1742     instrument or audio output device change
1743 schoenebeck 654
1744 schoenebeck 620 * LSCP server:
1745 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1746 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1747 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1748 schoenebeck 609
1749 schoenebeck 668 * linuxsampler application:
1750     - added command line parameters --lscp-addr and --lscp-port to override
1751     default IP address and port of LSCP server
1752    
1753 schoenebeck 579 Version 0.3.1 (24 May 2005)
1754    
1755     * initial release
