NKSP: Reduced code for parsing NKSP variable declarations:

* Use 2 generalized grammar rules with optional components (i.e. optional
  value assignment and optional variable qualifiers) instead of previous
  linear combinations of grammar rules, which also fixes some edge case.

* Bumped version (2.1.1.svn44).

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 3726 - Fixed potential crash with high pitch at end of RAM playback.
54 schoenebeck 3550
55 schoenebeck 3551 * Real-time instrument scripts:
56     - Added method ScriptVM::setExitResultEnabled() which allows to
57     explicitly enable the built-in exit() function to optionally accept
58     one function argument; the value of the passed exit() function
59     argument will then become available by calling
60     VMExecContext::exitResult() after script execution.
61 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
62 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
63     with a regular character (a-z or A-Z); starting them with a digit or
64     underscore is not allowed.
65     - NKSP parser fix: equal comparison operator "=" and not equal comparison
66     operator "#" must only accept integer operands.
67     - NKSP language: Implemented support for standard units like Hertz, seconds,
68     Bel including support for metric unit prefixes; so one can now e.g.
69     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
70     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
71     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
72     - NKSP language: Introduced "final" operator "!" which is specifically
73     intended for synthesis parameter values to denote that the synthesis
74     parameter value is intended to be the "final" value for that synthesis
75     parameter that should explicitly be used by the engine and thus causing
76     the sampler engine to ignore all other modulation sources for the same
77     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
78     variable or formula with this new "!" operator the expression is marked as
79     being "final".
80 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
81     and their potential metric prefix token.
82 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
83     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
84     - NKSP language: Added support for NKSP real number (floating point) script
85     variables (declare ~foo).
86     - NKSP language: Added support for NKSP real number (floating point) array
87     script variables (declare ?foo[]).
88     - Built-in script function "message()" accepts now real number argument as
89     well.
90     - Added built-in script function "real_to_int()" and its short hand form
91     "int()" for casting from real number to integer in NKSP scripts.
92     - Added built-in script function "int_to_real()" and its short hand form
93     "real()" for casting from integer to real number in NKSP scripts.
94 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
95     argument as well.
96 schoenebeck 3577 - Built-in script functions may have a different return type depending on
97     the arguments passed to the function.
98     - Built-in script function "abs()" optionally accepts and returns real
99     number.
100     - Built-in script functions "min()" and "max()" optionally accept real
101     number arguments and return real number as result in that case.
102 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
103     built-in functions (added methods VMFunction::returnUnitType() and
104     VMFunction::returnsFinal() for that purpose which must be implemented by
105     built-in function implementations).
106     - NKSP language: Allow metric unit prefixes of numeric scalar and array
107     variables to be changed freely at runtime (unlike unit types like Hz etc.
108     which are still sticky, parse-time features of variables which cannot be
109     changed at runtime for the intentional sake of determinism).
110     - NKSP language: 'final' values are prohibited for array variables for now
111     (attempt causes a parsers error).
112     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
113     conditions of runtime control structures like if(), while(), select()
114     (attempt causes a parser error).
115     - NKSP VM API: Allow built-in functions to perform their own, individual
116     parse time checks of arguments going to be passed to the function at
117     runtime (added method VMFunction::checkArgs() for that purpose).
118     - NKSP language: raise parser warning if only one operand of binary
119     operators (like logical 'or' comparison) contain a 'final' value (because
120     it would always yield in a 'final' result in such cases).
121     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
122     different metric unit prefixes, which will behave as expected (e.g.
123     result of expression '1000us < 2ms' is true).
124     - NKSP language: Allow adding values with different metric unit prefixes
125     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
126     - NKSP language: Allow subtracting values with different metric unit
127     prefixes (e.g. result of expression '1ms - 20us' is '980us').
128     - NKSP language: Allow multiplying with any metric unit prefixes
129     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
130     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
131     we don't have any considerable practical use for a term like '4s^2'
132     (hence any attempt multiplying two unit types still causes parser error).
133     - NKSP language: Allow dividing by any metric unit prefixes and allow
134     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
135     yields in unit free result '8'). So this is now a way to cast units away
136     e.g. for passing the result to other expressions, certain function calls
137     or variables which are not accepting any units (or that specific unit).
138     - NKSP language: integer arrays and real number arrays can now be converted
139     to strings (e.g. for dumping their content with message() calls for
140     script debugging purposes).
141     - NKSP language: expressions and variables with units are now correctly
142     casted to strings (e.g. with message() calls).
143     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
144     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
145     floating point tolerances into account.
146     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
147     VMScalarNumberExpr::evalCastReal().
148     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
149     'VMIntArrayExpr' and 'VMRealArrayExpr'.
150     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
151     unitFactor() (runtime) methods.
152     - Built-in function "exit()" supports now returning units and 'final'ness
153     for test cases.
154     - The following built-in functions support now units as well: "abs()",
155     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
156     "real_to_int()", "int()", "int_to_real()" and "real()".
157     - Built-in functions "array_equal()", "search()" and "sort()" support now
158     real number arrays (correctly) as well.
159     - Added individual parse time checks of arguments to be passed to built-in
160     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
161     "array_equal()" and "search()" specific for their individual purposes.
162 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
163     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
164     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
165     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
166     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
167     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
168     isScalarNumber() -> isNumber()).
169 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
170     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
171     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
172     as convenient methods for automatically converting values to expected
173     metric value basis.
174     - Built-in function "wait()" accepts now both integers and real numbers as
175     argument.
176 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
177     VMFunction::argType(vmint iArg) which was already superseded by its new
178     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
179     - NKSP parser: if wrong argument type was passed to a built-in function and
180     that built-in function accepts more than one data type for the argument,
181     then show all supported data types as parser error message.
182 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
183     unit type as well for its 3rd and 4th function arguments.
184     - The following built-in functions accept now real numbers as well for their
185     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
186     "change_attack()", "change_decay()", "change_release()",
187     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
188     "change_cutoff_sustain()", "change_cutoff_release()",
189     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
190     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
191     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
192     - Fixed built-in function "change_play_pos()" not having accepted metric
193     prefixes at all.
194 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
195     with unit type (for their 2nd argument) as if they were relative values
196     (that is as if they were passed without a unit type): "change_attack()",
197     "change_decay()", "change_release()", "change_cutoff_attack()",
198     "change_cutoff_decay()", "change_cutoff_release()".
199     - Fixed the following built-in functions having applied completely wrong
200     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
201     respective EGs being their modulation sink assume uint data type with
202     value range 0..1000 instead of 0.0..1.0.
203     - Added individual parse-time checks of function arguments for the following
204     built-in functions: "play_note()", "note_off()", "set_event_mark()",
205     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
206     "change_decay()", "change_release()", "change_cutoff_attack()",
207     "change_cutoff_decay()", "change_cutoff_release()",
208     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
209     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
210     "change_pan_time()".
211     - Don't abort function call if unit type was used and at the same time
212     'final' operator was omitted for the primary value argument of the
213     following built-in functions: "change_cutoff()", "change_attack()",
214     "change_decay()", "change_release()", "change_cutoff_attack()",
215     "change_cutoff_decay()", "change_cutoff_release()",
216     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
217     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
218     "change_pan_time()", instead imply 'final'ness at runtime and raise an
219     appropriate parser warning at parse time.
220 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
221     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
222     "cos()", "tan()", "asin()", "acos()", "atan()".
223     - Added built-in script real number constant "~NI_MATH_PI".
224     - Added built-in script real number constant "~NI_MATH_E".
225 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
226 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
227 schoenebeck 3690 - NKSP language: Added support for RPN event handler
228     ("on rpn ... end on" in instrument scripts).
229     - NKSP language: Added support for NRPN event handler
230     ("on nrpn ... end on" in instrument scripts).
231     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
232     may be read from the new RPN/NRPN script handlers to get the (N)RPN
233     parameter that had been changed and its new value.
234     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
235     which are identifying the new (N)RPN handlers as such at script runtime.
236 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
237     - Implemented built-in script function "set_nrpn()".
238 schoenebeck 3714 - Fix: built-in functions returning an array type were broken and caused a
239     crash when the built-in function's (supposed to be array) result value was
240     used by the script VM.
241 schoenebeck 3715 - Removed upper value constraint for 2nd argument of built-in functions
242     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
243     "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
244     "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
245     "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
246     the LFO frequency / resonance / cutoff frequency.
247 schoenebeck 3728 - Reduced code involved for parsing NKSP variable declarations by using 2
248     generalized grammar rules with optional components (i.e. optional value
249     assignment and optional variable qualifiers) instead of previous linear
250     combinations of grammar rules, which also fixes some edge case.
251 schoenebeck 3551
252 schoenebeck 3550 * test cases:
253 schoenebeck 3548 - Fixed compiler errors in test cases.
254     - Updated README for how to compile & run test cases.
255     - Updated test case
256     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
257     expected behaviour of the Mutex class implementation (recursive
258     mutex type).
259 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
260     functions.
261 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
262 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
263     int_to_real(), real(), real_to_int() and int(), as well as for the
264     plus, minus and negate language operators.
265 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
266     'final' operator usage cases.
267     - Added NKSP test cases for (floating point tolerance aware) real number
268     equalness / unequalness comparison.
269 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
270     initialization of arrays.
271 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
272     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
273     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
274 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
275 schoenebeck 3693 - Added NKSP test cases for core built-in variables.
276 schoenebeck 3727 - Added thorough NKSP test cases for variable declarations.
277 schoenebeck 3548
278 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
279     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
280     behaviour for start_level_mid.
281 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
282     level (see discussion "GigaStudio LFO compatibility" on mailing list
283     from 2019-09-26 for details).
284 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
285     see discussion "GigaStudio LFO compatibility" on mailing list from
286     2019-09-26 for details).
287 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
288     either sine [default], triangle, saw or square).
289     - Format extension: Added support for LFO phase displacement (0��..360��).
290     - Format extension: Added support for flipping LFO polarity on LFO 3
291     (in the original gig format this was only available for LFO 1 and LFO 2).
292 schoenebeck 3646 - Format extension: Support for additional filter types:
293     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
294     bandreject 2-pole.
295 schoenebeck 3719 - Fixd potential crash with polynomial interpolator and max. pitch.
296 schoenebeck 3721 - If minimum cutoff is defined, remap cutoff controller CC values to really
297     span the entire possible cutoff range (and avoiding a dead controller
298     zone).
299 schoenebeck 3611
300 persson 3593 * SFZ format engine:
301     - Fixed support for regions with loccN/hiccN conditions on more than one
302     MIDI controller.
303    
304 schoenebeck 3612 * Benchmarks:
305     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
306     algorithm (since result of 2nd run was not accumulated).
307     - Added benchmark for saw wave (benchmarks/saw.cpp).
308     - Added benchmark for sine wave (benchmarks/sine.cpp).
309     - Added benchmark for square wave (benchmarks/square.cpp).
310     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
311     which are large enough on modern systems.
312    
313 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
314 schoenebeck 3381
315     * Real-time instrument scripts:
316     - Fixed behavior of built-in NKSP functions change_sustain(),
317     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
318     and change_cutoff_release().
319    
320 schoenebeck 3444 * general changes:
321     - Only play release trigger samples on sustain pedal up if this behaviour
322     was explicitly requested by the instrument (otherwise only on note-off).
323 persson 3455 - Fixed compiler warnings.
324     - Fixed compilation error when cross-compiling to Mac.
325 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems

327     - LSCP doc: Be more clear describing the two distinct approaches
328     of using external vs. internal effects (see bug #169).
329 schoenebeck 3514 - "optional" class: Fixed comparison operators.
330 schoenebeck 3444
331 schoenebeck 3448 * Gigasampler/GigaStudio format engine:

348     - Added support for sfz extension opcode 'script' which may be used to
349     load real-time instrument script file (NKSP script language).
350 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
351 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
352 persson 3291 - sfz parser: allow missing space between header and opcode
353 persson 2856
354 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
355 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
356     cutoff settings.
357 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
358     all if an up-pitch of more than 40 semi tones was requested (I don't
359     think there is any stock gig sound that requires this behavior to
360     resemble its original sound).
361 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
362     be aborted (as LinuxSampler extension to the original GigaStudio 4
363     format).
364 schoenebeck 3072
365 persson 2837 * general changes:
366     - fixed printf type errors (mostly in debug messages)
367 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
368 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
369     allowing to sort data efficiently in real-time safe manner.
370     - RTList class: added methods for moving/inserting elements to arbitrary
371     position within a list.
372     - RTList class: added method fromPtr() for creating an Iterator object from
373     a raw element pointer.
374     - Attempt to partly fix resetting engine channels vs. resetting engine, an
375     overall cleanup of the Reset*(), ConnectAudioDevice(),
376     DisconnectAudioDevice() API methods would still be desirable though,
377     because the current situation is still inconsistent and error prone.
378 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
379     being directly assigned to a keyboard key. This allows more fine graded
380     processing of voices, which is i.e. required for certain instrument
381     script features.
382 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
383     (CC #64) events.
384     - Fix: Release trigger voices can now also distinguish correctly between
385     note-off and sustain pedal up events.
386 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
387     (while slow rate of crossfade smoother is preserved) to allow quick
388     volume and pan changes by instrument scripts for instance.
389 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
390     properly and thus were ignored for certain uses.
391 schoenebeck 3018 - Added new C++ API method
392     VirtualMidiDevice::SendChannelPressureToSampler().
393 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
394     sub threads is 16-byte aligned
395 schoenebeck 3054 - fixed numerous compiler warnings
396 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
397 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
398     fixes potential undefined behavior.
399 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
400     have a valid sample mapped (fixes bug #252).
401     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
402 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
403     subsequent optional argument due to glibc's implementation oddity
404     which expects a "=" sign, but no space between them.
405 persson 2837
406 schoenebeck 2866 * packaging changes:
407     - removed unnecessary dependency to libuuid
408     (originated by libgig's usage of it)
409 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
410     auto detect whether it (sh/c)ould output its messages in color.
411 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
412     substitution variable.
413     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
414 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
415     linuxsampler with instruments DB support.
416 schoenebeck 2866
417 schoenebeck 2871 * Real-time instrument scripts:
418     - Implemented scheduler for delayed MIDI events and for suspended scripts.
419     - Built-in script function "wait()": implemented support for function's
420     "duration-us" argument, thus scripts using this function are now
421     correctly resumed after the requested amount of microseconds.
422     - Built-in script function "play_note()": implemented support for
423     function's "duration-us" argument, thus notes triggered with this
424     argument are now correctly released after the requested amount of
425     microseconds.
426     - Fix: script events were not cleared when engine channel was reset,
427     potentially causing undefined behavior.
428     - Fixed crash which happened when trying to reference an undeclared
429     variable.
430 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
431     special value -1 for "duration-us" argument, which will cause the
432     triggered note to be released once the original note was released.
433 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
434     - Added new API method ScriptVM::syntaxHighlighting() which provides
435     a convenient syntax highlighting backend for external instrument
436     script editor applications.
437 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
438     - Extended parser issues to provide not only first line and first
439     column, but also last line and last column of issue (thus marking
440     the precise span of the issue within the source code).
441 schoenebeck 2902 - Reload script automatically after being modified by an instrument
442     editor.
443 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
444     like "on note end on".
445 schoenebeck 2931 - Implemented built-in script function "change_vol()".
446     - Implemented built-in script function "change_tune()".
447     - Implemented built-in script function "change_pan()".
448 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
449     - Implemented built-in script function "change_reso()".
450     - Implemented built-in script function "event_status()".
451     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
452     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
453     "event_status()" function.
454     - NKSP language: Added support for bitwise operators ".or.", ".and."
455     and ".not.".
456     - NKSP language scanner: Fixed IDs matching to require at least one
457     character (i.e. when matching function names or variable names).
458     - NKSP language scanner: disabled unusued rules.
459 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
460     be distinguished engine internally from "real" MIDI note on/off
461     events in order to avoid misbehaviors like hanging notes.
462 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
463     - Implemented built-in script variable "$NKSP_REAL_TIMER".
464     - Implemented built-in script variable "$NKSP_PERF_TIMER".
465     - Implemented built-in script variable "$ENGINE_UPTIME".
466 schoenebeck 2945 - Implemented built-in script function "inc()".
467     - Implemented built-in script function "dec()".
468     - NKSP language fix: division expressions were evaluated too often.
469     - NKSP language fix: string concatenation operator was right
470     associative instead of left (to right).
471 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
472     (i.e. "if end if").
473 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
474     - Implemented built-in script variable "$NI_CALLBACK_ID".
475     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
476     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
477     - Added support for read-only built-in variables (respectively

485     - Implemented built-in script function "change_decay()".
486     - Implemented built-in script function "change_release()".
487 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
488     synthesis parameter changes immediately in case the respective note
489     was triggered at the same time, instead of scheduling the parameter
490     change, especially because it would cause some parameter types's
491     changes either to be ramped (i.e. change_vol()) or other types even
492     to have not effect at all (i.e. change_attack()).
493 schoenebeck 2965 - Implemented built-in script function "sh_left()".
494     - Implemented built-in script function "sh_right()".
495 schoenebeck 2970 - Implemented built-in script function "min()".
496     - Implemented built-in script function "max()".
497 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
498     was loaded.
499     - NKSP built-in wait() script function: abort script execution if
500     a negative or zero wait time was passed as argument (since this is
501     a common indication of a bug either of the script or even of the
502     engine, which could lead to RT instability or even worse).
503 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
504     threatening scripts.
505 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
506 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
507     initializer list to an array variable.
508 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
509 schoenebeck 3076 - Implemented built-in script function "in_range()".
510 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".

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

605 schoenebeck 2871
606 schoenebeck 3050 * Instruments DB:
607     - Fixed memory access bug of general DB access code which lead to
608     undefined behavior.
609 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
610     - The instrument DB path of linuxsampler's --create-instruments-db argument
611     is now optional, if it is missing, then a default location is used.
612 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
613     - Added support for scanning Sound Font (.sf2) files.
614 schoenebeck 3101 - Fixed undefined DB transaction behavior.
615 schoenebeck 3050
616 schoenebeck 2787 Version 2.0.0 (15 July 2015)
617 schoenebeck 1993

648     on the process's main thread
649 persson 2478 - fixed build error on newer MinGW
650     - support building with older jack versions
651     - support building with spaces in vst sdk path
652 persson 2519 - enabled automake 'subdir-objects' option and moved external
653     source references (vst, au, asio) from makefiles to cpp files,
654     in order to get rid of warnings from automake 1.14
655 persson 2382
656 persson 2086 * general changes:
657 iliev 2012 - Refactoring: moved the independent code from
658     the Gigasampler format engine to base classes
659 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
660     respective profiling code is currently broken
661 schoenebeck 2053 - Introduced support for optional environment variable
662     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
663     where the sampler shall look for instrument editor plugins
664     (patch by Luis Garrido, slightly modified).
665 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
666     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
667     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
668     note (in this implementation of the sampler its simply hard routed to
669     the 1st effect send of the sampler channel, no matter what the actual
670     effect type is)
671     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
672     note (in this implementation of the sampler its simply hard routed to
673     the 2nd effect send of the sampler channel, no matter what the actual
674     effect type is)
675 schoenebeck 2124 - implemented support for internal LADSPA effects
676 schoenebeck 2140 - raised limit of program change queue from 100 to 512
677     (as suggested by Alex Stone)
678 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
679 iliev 2296 - experimental support for per voice equalization
680 iliev 2306 - added command line option --exec-after-init
681 schoenebeck 2330 - Introduced new C++ API method:
682     EngineChannel::InstrumentFileName(int index)
683     allowing to retrieve the whole list of files used for the loaded
684     instrument on an engine channel (a.k.a. part). Some GigaStudio
685     instruments for example are splitted over several files like
686     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
687 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
688     - Added new C++ API method Sampler::GetGlobalMaxStreams().
689     - Added new C++ API method Sampler::SetGlobalMaxVoices().
690     - Added new C++ API method Sampler::SetGlobalMaxStreams().
691 schoenebeck 2377 - Various "const" and "restrict" optimizations.
692 persson 2382 - all engines: add pan CC value to instrument pan parameter before
693     applying panning, instead of using two separate pan functions in
694     series (#182)
695 persson 2427 - added a lock guard class for exception safe mutex handling and
696     used it everywhere appropriate
697 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
698     - Exposed scale tuning to C++ API (along to the already existing standard
699     SysEx way).
700 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
701     and broken for ppc64. (Seq_cst loads and stores are actually not
702     used in LS, so the bug wasn't noticable.)
703     - lsatomic.h: added ARMv7 support
704 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
705     added various new C++ methods for this new feature / design change, old
706     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
707     as deprecated but are still there and should provide full behavior
708     backward compatibility).
709     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
710     unsafe and caused compilation error with clang 2.x).
711 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
712 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
713     sampler from the command line by providing LSCP aware features.
714 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
715     - VirtualMidiDevice: Added support for bank select (MSB & LSB).

717 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
718     polyphonic key pressure events (so far polyphonic pressure was not
719     supported at all, and channel pressure was rerouted as CC128 but not
720     used so far).

722     code is shared by all sampler engine implemementations, however only the
723     gig file format currently provides support for storing instrument scripts

1125     took the full preloading time and on 1st program change the respective
1126     instrument was completely reloaded again.
1127 persson 2277 - fixed handling of rapid bank select and program change messages

1151 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1152     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1153     practically irrelevant, however it caused problems with the new LSCP
1154     shell's auto completion feature).
1155 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1156     after each other (fixes #231).

1208     stacktrace mechanism seems to be broken on most systems at the moment)
1209 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1210     a pointer to the launched InstrumentEditor object
1211 schoenebeck 1876 - added optional 3rd party user data parameter for following

1281     if no DB is present it automatically creates the .linuxsampler subdir
1282     and then creates an empty DB
1283 persson 1943 - fixed recursive import, which was broken on Windows
1284 iliev 1603
1285 persson 1644 * Gigasampler format engine:

1297     connected to the respective MIDI input port the SysEx message arrived
1298     on)
1299 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1300     sometimes wrongly killed in the same buffer, causing no sound to
1301     be played
1302 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1303     which is usally used to switch a part between chromatic sounds and
1304     drumkit sounds (as opposed to their common default setting of MIDI
1305     part 10 being a drumkit part and all other ones chromatic parts), in
1306     LS however one can switch between the first 16 MIDI instrument maps
1307     defined for the sampler
1308 persson 1764 - made it possible to create multiple sample channels even if the

1313     sampler engine anymore
1314     - re-cache samples in case they were changed by an instrument editor,
1315     e.g. when a sample was added while playing (#82)
1316 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1317     same time stamp as the voice's note-on event and occured both in the
1318     same audio fragment cycle (fixes bug #112)
1319 persson 1858 - added support for the "fine tune" and "pitch bend range"
1320     instrument-level gig parameters
1321     - fixed minor artifacts in pitch bend handling
1322 schoenebeck 1860 - added support for GS Reset SysEx message
1323 persson 1862 - allow gig files to use unlimited downward pitch shifting
1324     - added a limit check for upward pitch shifting
1325 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1326     note was silent
1327 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1328     same time a new instrument was loading
1329 persson 1644
1330 schoenebeck 1687 * LSCP server:
1331     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

1333     Note-On and Note-Off events are sent via this LSCP event)
1334 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1335     react on MIDI data arriving on certain MIDI input devices (so far only
1336     Note-On and Note-Off events are sent via this LSCP event)
1337 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1338     SET DB_INSTRUMENT FILE_PATH
1339 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1340     frontends to send MIDI messages to specific sampler channel
1341     - added two additional fields to GET FILE INSTRUMENT INFO command -
1342     KEY_BINDINGS and KEYSWITCH_BINDINGS
1343 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1344     was incorrect
1345 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1346 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1347     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1348     be triggered respectively
1349     - added new LSCP command "SET STREAMS" to globally alter the maximum
1350     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1351     which will be triggered respectively
1352 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1353     a gigedit file dialog is opened)

1396     - bugfix: the thread used by an editor plugin didn't die when the
1397     editor closed
1398 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1399     out all the space. operator--() did not apply size_mask after
1400     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1401     order to avoid problems with the _NonVolatileReader functions.
1402     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1403     GetWriteSpace(). Since this function is currently only used in
1404     the stream's qsort() compare function, it didn't trigger any
1405     bugs.
1406     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1407     24bit mode too. Faster method to read 24bit words on little
1408     endian machines (x86): replaced 3 byte reads + shifts with a 1
1409     unaligned 32bit read and shift
1410     - experimental support for MS Windows (MIDI input via MME, AUDIO
1411     output via ASIO)
1412     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1413 iliev 1541 - support for monitoring the total number of active disk streams
1414     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1415     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1416 persson 1455
1417 senoner 1500 * AUDIO driver:
1418 persson 1534 - added Windows ASIO low latency audio driver
1419 senoner 1500
1420 senoner 1485 * MIDI driver:
1421 schoenebeck 1495 - added MME Windows MIDI driver
1422 senoner 1485
1423 schoenebeck 1471 * LSCP server:
1424     - added support for Windows style path / filenames, however with
1425     forward slash path separators instead of backslash
1426     (i.e. "C:/foo/bar.gig")
1427 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1428     apostrophes as well
1429 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1430     "LIST FILE INSTRUMENTS <file>" and
1431     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1432     about an arbitrary instrument file on the system where the sampler is
1433     running on
1434 schoenebeck 1471
1435 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1436 schoenebeck 947
1437 schoenebeck 1065 * packaging changes:
1438 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1439     API header files anymore
1440 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1441     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1442 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1443     capable to execute our autoconf environment, thus no need anymore
1444     to maintain the compile time configuration file (osx/version.h) for
1445     OSX manually (patch by Toshi Nagata)
1446 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1447     parameters
1448 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1449     C++ API header files, all implementation internal global definitions
1450     are now in global_private.h
1451     - atomic.h is not exposed to the C++ API anymore
1452     - no need to include config.h anymore for using LS's API header files
1453     - fixed warnings in API doc generation
1454 schoenebeck 1065
1455 schoenebeck 947 * general changes:
1456     - replaced the old, confusing MIDI program change mechanism by a
1457     flexible MIDI instrument mapper which allows to map arbitrary
1458 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1459 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1460     loaded on the respective channel when such MIDI program change
1461     messages arrive, beside that, each entry allows to define a life-time
1462     strategy for the instrument, so the user can define whether the
1463     instrument should i.e. be permanently loaded (to be able to switch
1464     quickly among sounds) or i.e. loaded just on demand when the
1465     respective program change arrives (to safe RAM space), as well as a
1466     global volume factor for each entry, so the user can adjust the volume
1467     dynamic of his mapped instrument collection without having to modify
1468 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1469     MIDI instrument maps and assign each sampler channel individually
1470     a certain map, so that i.e. separation of normal instruments and
1471     drumkits is possible
1472 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1473     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1474 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1475     due to a constant size RingBuffer FIFO which is now replaced by a
1476     dynamic (unlimited) size std::list FIFO
1477 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1478     output channels for being processed by external effect processors
1479     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1480     controllers
1481 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1482 iliev 1130 - Implemented new, improved notification system
1483 schoenebeck 1149 - fixed compilation errors regarding OSX
1484     (patch by Toshi Nagata)
1485 iliev 1161 - implemented instruments database
1486 iliev 1345 - added support for escape sequences to the instruments database
1487 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1488     within the sampler's process (by using instrument editor plugins),
1489     you'll notice the new "Registered instrument editors:" message on
1490 schoenebeck 1407 startup, added a new LSCP command:
1491     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1492 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1493     given sampler channel, the plugin path can be overridden at compile
1494     time with ./configure --enable-plugin-dir=/some/dir
1495 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1496     in the sampler's process to safely edit instruments while playing
1497     without a crash (hopefully) by either suspending single regions
1498     wherever possible or if unavoidable whole engine(s)
1499 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1500     policy and priority on thread level, set a minimum stack size for
1501     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1502     threads simply inherited properties of starting thread instead of
1503     setting their own policy and priority
1504 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1505     main process did not wait for the stack trace process to finish
1506     its output
1507 persson 1248 - fixed some minor memory leaks
1508 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1509     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1510 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1511     register, to avoid relocations in the text segment at runtime)
1512 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1513 schoenebeck 947
1514     * MIDI driver:
1515     - dispatch bank select (MSB and LSB) messages
1516    
1517 schoenebeck 1049 * audio driver:
1518     - the ALSA audio output driver parameters now reflect the correct
1519     parameter value ranges for the respective selected sound card
1520     (patch by Till Wimmer, a bit fixed and extended)
1521    
1522 persson 951 * Gigasampler format engine:
1523     - if a filter is used and EG2 finishes before EG1, let the voice
1524     die when EG2 has finished (this fixes a problem with clicks and
1525     voice starvation for some gigs)
1526 persson 1038 - playback is no longer disabled during instrument loading
1527     - all notes playing on a channel that changes its instrument keep
1528     playing with the old instrument until they get a note off
1529     command
1530 persson 1039 - EG fix: a release value of zero could cause noises or crash
1531 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1532 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1533     above max sustain level, which means that there is a decay phase
1534     even if sustain is 100%
1535 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1536     noises or crashes
1537 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1538 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1539     supplied to the configure script (fixes #46)
1540 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1541     instead of a fix value
1542 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1543     127 (solo mode) only kill voices if the respective mode really
1544     changed
1545 persson 951
1546 schoenebeck 1244 * LSCP server:
1547     - fixed compile time error for old Bison versions
1548     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1549 schoenebeck 1245 - parser now supports extended ASCII character set
1550     (up to ASCII code 255, i.e. includes now umlauts and accents)
1551     - filename arguments in LSCP commands now allow to use escape
1552     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1553     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1554     code value like \xf2) (fixes bug #24)
1555 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1556     least one of their text-based parameters (i.e. name, description):
1557     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1558     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1559     "SET DB_INSTRUMENT_DIRECTORY NAME",
1560     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1561     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1562     "FIND DB_INSTRUMENT_DIRECTORIES"
1563 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1564     occured, the unexpected character and the actually expected, possible
1565     character(s), the latter only if less than 5 possibilities)
1566 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1567     settings
1568 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1569     of strings were treated as being one string containing commas
1570     (fixes #57)
1571 schoenebeck 1244
1572 iliev 959 * Bug fixes:
1573     - fixed crash occurring on certain LSCP scripts (Bug 39)
1574 persson 1038 - another thread safety fix for lscp "load engine" and "set
1575     channel audio output device"
1576 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1577     on a sampler channel with connected MIDI device
1578 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1579     device connected to a sampler channel to number less then or equal
1580     to the index of the port to which the sampler channel is connected.
1581 iliev 1296 - The previous bindings were not been disconnected when altering
1582     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1583     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1584 iliev 1297 - The active stream/voice count statistic was incorrect.
1585 iliev 1298 - notification events were not been sent for some sampler
1586     channel changes
1587 iliev 1305 - added default min and max values to restrict the number of allowed
1588     audio output channels and MIDI input ports
1589 iliev 1306 - the connection to the PCM interface is now closed when destroying
1590     an audio output device
1591 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1592 iliev 959
1593 schoenebeck 1221 * test cases:
1594     - updated and fixed (haven't been touched in a while)
1595    
1596 schoenebeck 937 Version 0.4.0 (24 November 2006)
1597 persson 696
1598 schoenebeck 697 * packaging changes:
1599 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1600     to post-(un)install steps; added devel package for liblinuxsampler;
1601     to linuxsampler.spec (RPM)
1602 schoenebeck 697 - install necessary development header files for allowing 3rd party
1603     applications to link against liblinuxsampler
1604     - liblinuxsampler's API documentation can be generated with 'make docs'
1605     (Doxygen required)
1606 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1607     implementation (currently either an integer math solution or a
1608     di-harmonic approximation), automatic detection can be overriden
1609     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1610     configure script argument though (mandatory for cross-compilation)
1611 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1612     provided some on his own (as CXXFLAGS)
1613 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1614     messages
1615 schoenebeck 852 - added compile time options to allow disabling the various audio and
1616     MIDI drivers
1617 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1618     (patch by Ebrahim Mayat)
1619 schoenebeck 697
1620 persson 696 * Gigasampler format engine:
1621 schoenebeck 738 - extensive synthesis optimization
1622     (reimplementation of EGs and LFO(s), removed synthesis parameter
1623     prerendering and the synthesis parameter matrix in general, splitting
1624     each audio fragment into subfragments now where each subfragment uses
1625 persson 830 constant pitch and filter coefficients. The volume coefficient is
1626     linearly interpolated inside a subfragment, unless
1627     --disable-interpolate-volume is set.)
1628 persson 696 - fine tuning of the EG modulation parameters
1629 persson 729 - improved filter cutoff calculation by adding support for the
1630     following gig parameters: Cutoff freq (used when no cutoff
1631     controller is defined), Control invert, Minimum cutoff, Velocity
1632 persson 791 curve and Velocity range. The keyboard tracking now scales
1633     cutoff frequency instead of resonance.
1634 persson 877 - added support for gig parameter Resonance.
1635 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1636 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1637     which can be overridden with --enable-global-attenuation
1638 persson 783 - EG fixes: made the length of "attack hold" stage more
1639     accurate. Release stage can now start before attack stage
1640 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1641     time now has a minimal value to prevent clicks.
1642 persson 799 - fixed pitch changes larger than one octave
1643 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1644     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1645     all modes can be altered via standard GM messages, that is CC5 for
1646     altering portamento time, CC65 for enabling / disabling portamento
1647     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1648 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1649     parameter) and crossfade
1650 persson 831 - added support for the "attenuation controller threshold" gig
1651     parameter
1652 persson 832 - added smoothing of volume changes caused by control change
1653     messages
1654 persson 865 - sample loop parameters are now taken from the DimensionRegion
1655     instead of the wave chunk
1656     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1657     not equal to a power of two
1658 persson 877 - reimplementation of the filter algorithm. The new filter is more
1659     accurate and supports all gig filter types, including bandreject
1660     and lowpass turbo.
1661 persson 903 - real support for 24 bit samples - samples are not truncated to
1662     16 bits anymore
1663     - support for aftertouch (channel pressure, not polyphonic
1664     aftertouch)
1665 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1666     amplifying from 0)
1667 persson 696
1668 schoenebeck 711 * LSCP server:
1669     - fixed application exit on broken pipe error (fixes bug #20)
1670 iliev 793 - fixed the notification messages delay due to lack of
1671     network activity (fixes bug #26)
1672 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1673     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1674 schoenebeck 711
1675 schoenebeck 838 * audio driver:
1676     - added aRts audio output driver (by no means RT safe)
1677    
1678 schoenebeck 775 * MIDI driver:
1679     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1680     messages several times instead of once
1681 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1682     for events (i.e. for offline rendering based MIDI drivers)
1683 persson 922 - added checks for bad MIDI data
1684 schoenebeck 775
1685 schoenebeck 900 * linuxsampler application:
1686     - show available sampler engine types on startup
1687    
1688 schoenebeck 705 * general changes:
1689     - support for muting sampler channels and solo mode of the same, two new
1690     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1691     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1692     introduced for this, the behavior is the same like on a mixer console
1693 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1694     --enable-process-muted-channels which can be used to enable the
1695     processing of muted channels.
1696 iliev 777 - support for sostenuto pedal
1697 iliev 779 - support for monitoring the total number of active voices
1698 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1699     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1700 persson 835 - fixed some memory management errors
1701 persson 841 - fixed some concurrency problems that could lead to crashes when
1702     LSCP commands were executed
1703 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1704     sampler channel (fixes bug #36)
1705 schoenebeck 705
1706 schoenebeck 692 Version 0.3.3 (15 July 2005)
1707 schoenebeck 686
1708     * packaging changes:
1709     - fixed compilation with gcc 4.0
1710    
1711 schoenebeck 687 * Gigasampler format engine:
1712     - LFO preprocessing was performed even though the respective LFO was
1713     disabled by the instrument patch (minor efficiency fix)
1714 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1715     for volume ramp downs in the same fragment (needed for current voice
1716     stealing implementation) then simply inform the user with a warning
1717     about possible click sounds and reduce the volume ramp down
1718     appropriately instead of cancelling the audio device connection
1719 schoenebeck 687
1720 schoenebeck 677 Version 0.3.2 (24 June 2005)
1721 schoenebeck 609
1722     * packaging changes:
1723     - updated autotools build files to compile on OS X
1724     (conditional compilation of CoreMIDI and MidiShare drivers)
1725 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1726     './configure --disable-asm' (definitely not recommended)
1727 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1728     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1729     (due to 'dist-bzip2' automake option)
1730 schoenebeck 649
1731     * Gigasampler format engine:
1732     - support for the gig parameters for "release velocity response" curves
1733     - fine tuning of the EGADSR envelope
1734     - volume of release triggered samples now depends on note-on velocity,
1735     note length and gig parameter "release trigger decay" instead of
1736     note-off velocity.
1737 schoenebeck 663 - revised voice stealing
1738     (fixes crash and endless loop caused by voice stealing)
1739 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1740 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1741     instead of when the respective voice is actually launched
1742     (fixes undefined behavior if stolen voices belonged to a key group -
1743     this case was followed by a "killed voice survived" error message)
1744 schoenebeck 669 - fixed minor issue with null/silence samples
1745     (those stole voices even though they don't need a voice at all which
1746     resulted in "voice stealing didn't work out" messages)
1747 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1748     instrument or audio output device change
1749 schoenebeck 654
1750 schoenebeck 620 * LSCP server:
1751 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1752 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1753 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1754 schoenebeck 609
1755 schoenebeck 668 * linuxsampler application:
1756     - added command line parameters --lscp-addr and --lscp-port to override
1757     default IP address and port of LSCP server
1758    
1759 schoenebeck 579 Version 0.3.1 (24 May 2005)
1760    
1761     * initial release
