* Added configure checks whether C++ compiler supports so called
  'designated initializers'.

* Bumped version (2.1.1.svn47).

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 3739 - Added configure checks whether C++ compiler supports so called
55     'designated initializers'.
56 schoenebeck 3550
57 schoenebeck 3551 * Real-time instrument scripts:
58     - Added method ScriptVM::setExitResultEnabled() which allows to
59     explicitly enable the built-in exit() function to optionally accept
60     one function argument; the value of the passed exit() function
61     argument will then become available by calling
62     VMExecContext::exitResult() after script execution.
63 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
64 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
65     with a regular character (a-z or A-Z); starting them with a digit or
66     underscore is not allowed.
67     - NKSP parser fix: equal comparison operator "=" and not equal comparison
68     operator "#" must only accept integer operands.
69     - NKSP language: Implemented support for standard units like Hertz, seconds,
70     Bel including support for metric unit prefixes; so one can now e.g.
71     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
72     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
73     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
74     - NKSP language: Introduced "final" operator "!" which is specifically
75     intended for synthesis parameter values to denote that the synthesis
76     parameter value is intended to be the "final" value for that synthesis
77     parameter that should explicitly be used by the engine and thus causing
78     the sampler engine to ignore all other modulation sources for the same
79     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
80     variable or formula with this new "!" operator the expression is marked as
81     being "final".
82 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
83     and their potential metric prefix token.
84 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
85     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
86     - NKSP language: Added support for NKSP real number (floating point) script
87     variables (declare ~foo).
88     - NKSP language: Added support for NKSP real number (floating point) array
89     script variables (declare ?foo[]).
90     - Built-in script function "message()" accepts now real number argument as
91     well.
92     - Added built-in script function "real_to_int()" and its short hand form
93     "int()" for casting from real number to integer in NKSP scripts.
94     - Added built-in script function "int_to_real()" and its short hand form
95     "real()" for casting from integer to real number in NKSP scripts.
96 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
97     argument as well.
98 schoenebeck 3577 - Built-in script functions may have a different return type depending on
99     the arguments passed to the function.
100     - Built-in script function "abs()" optionally accepts and returns real
101     number.
102     - Built-in script functions "min()" and "max()" optionally accept real
103     number arguments and return real number as result in that case.
104 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
105     built-in functions (added methods VMFunction::returnUnitType() and
106     VMFunction::returnsFinal() for that purpose which must be implemented by
107     built-in function implementations).
108     - NKSP language: Allow metric unit prefixes of numeric scalar and array
109     variables to be changed freely at runtime (unlike unit types like Hz etc.
110     which are still sticky, parse-time features of variables which cannot be
111     changed at runtime for the intentional sake of determinism).
112     - NKSP language: 'final' values are prohibited for array variables for now
113     (attempt causes a parsers error).
114     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
115     conditions of runtime control structures like if(), while(), select()
116     (attempt causes a parser error).
117     - NKSP VM API: Allow built-in functions to perform their own, individual
118     parse time checks of arguments going to be passed to the function at
119     runtime (added method VMFunction::checkArgs() for that purpose).
120     - NKSP language: raise parser warning if only one operand of binary
121     operators (like logical 'or' comparison) contain a 'final' value (because
122     it would always yield in a 'final' result in such cases).
123     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
124     different metric unit prefixes, which will behave as expected (e.g.
125     result of expression '1000us < 2ms' is true).
126     - NKSP language: Allow adding values with different metric unit prefixes
127     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
128     - NKSP language: Allow subtracting values with different metric unit
129     prefixes (e.g. result of expression '1ms - 20us' is '980us').
130     - NKSP language: Allow multiplying with any metric unit prefixes
131     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
132     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
133     we don't have any considerable practical use for a term like '4s^2'
134     (hence any attempt multiplying two unit types still causes parser error).
135     - NKSP language: Allow dividing by any metric unit prefixes and allow
136     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
137     yields in unit free result '8'). So this is now a way to cast units away
138     e.g. for passing the result to other expressions, certain function calls
139     or variables which are not accepting any units (or that specific unit).
140     - NKSP language: integer arrays and real number arrays can now be converted
141     to strings (e.g. for dumping their content with message() calls for
142     script debugging purposes).
143     - NKSP language: expressions and variables with units are now correctly
144     casted to strings (e.g. with message() calls).
145     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
146     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
147     floating point tolerances into account.
148     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
149     VMScalarNumberExpr::evalCastReal().
150     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
151     'VMIntArrayExpr' and 'VMRealArrayExpr'.
152     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
153     unitFactor() (runtime) methods.
154     - Built-in function "exit()" supports now returning units and 'final'ness
155     for test cases.
156     - The following built-in functions support now units as well: "abs()",
157     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
158     "real_to_int()", "int()", "int_to_real()" and "real()".
159     - Built-in functions "array_equal()", "search()" and "sort()" support now
160     real number arrays (correctly) as well.
161     - Added individual parse time checks of arguments to be passed to built-in
162     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
163     "array_equal()" and "search()" specific for their individual purposes.
164 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
165     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
166     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
167     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
168     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
169     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
170     isScalarNumber() -> isNumber()).
171 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
172     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
173     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
174     as convenient methods for automatically converting values to expected
175     metric value basis.
176     - Built-in function "wait()" accepts now both integers and real numbers as
177     argument.
178 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
179     VMFunction::argType(vmint iArg) which was already superseded by its new
180     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
181     - NKSP parser: if wrong argument type was passed to a built-in function and
182     that built-in function accepts more than one data type for the argument,
183     then show all supported data types as parser error message.
184 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
185     unit type as well for its 3rd and 4th function arguments.
186     - The following built-in functions accept now real numbers as well for their
187     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
188     "change_attack()", "change_decay()", "change_release()",
189     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
190     "change_cutoff_sustain()", "change_cutoff_release()",
191     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
192     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
193     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
194     - Fixed built-in function "change_play_pos()" not having accepted metric
195     prefixes at all.
196 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
197     with unit type (for their 2nd argument) as if they were relative values
198     (that is as if they were passed without a unit type): "change_attack()",
199     "change_decay()", "change_release()", "change_cutoff_attack()",
200     "change_cutoff_decay()", "change_cutoff_release()".
201     - Fixed the following built-in functions having applied completely wrong
202     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
203     respective EGs being their modulation sink assume uint data type with
204     value range 0..1000 instead of 0.0..1.0.
205     - Added individual parse-time checks of function arguments for the following
206     built-in functions: "play_note()", "note_off()", "set_event_mark()",
207     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
208     "change_decay()", "change_release()", "change_cutoff_attack()",
209     "change_cutoff_decay()", "change_cutoff_release()",
210     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
211     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
212     "change_pan_time()".
213     - Don't abort function call if unit type was used and at the same time
214     'final' operator was omitted for the primary value argument of the
215     following built-in functions: "change_cutoff()", "change_attack()",
216     "change_decay()", "change_release()", "change_cutoff_attack()",
217     "change_cutoff_decay()", "change_cutoff_release()",
218     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
219     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
220     "change_pan_time()", instead imply 'final'ness at runtime and raise an
221     appropriate parser warning at parse time.
222 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
223     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
224     "cos()", "tan()", "asin()", "acos()", "atan()".
225     - Added built-in script real number constant "~NI_MATH_PI".
226     - Added built-in script real number constant "~NI_MATH_E".
227 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
228 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
229 schoenebeck 3690 - NKSP language: Added support for RPN event handler
230     ("on rpn ... end on" in instrument scripts).
231     - NKSP language: Added support for NRPN event handler
232     ("on nrpn ... end on" in instrument scripts).
233     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
234     may be read from the new RPN/NRPN script handlers to get the (N)RPN
235     parameter that had been changed and its new value.
236     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
237     which are identifying the new (N)RPN handlers as such at script runtime.
238 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
239     - Implemented built-in script function "set_nrpn()".
240 schoenebeck 3714 - Fix: built-in functions returning an array type were broken and caused a
241     crash when the built-in function's (supposed to be array) result value was
242     used by the script VM.
243 schoenebeck 3715 - Removed upper value constraint for 2nd argument of built-in functions
244     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
245     "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
246     "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
247     "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
248     the LFO frequency / resonance / cutoff frequency.
249 schoenebeck 3728 - Reduced code involved for parsing NKSP variable declarations by using 2
250     generalized grammar rules with optional components (i.e. optional value
251     assignment and optional variable qualifiers) instead of previous linear
252     combinations of grammar rules, which also fixes some edge case.
253 schoenebeck 3729 - NKSP language parser: track code block locations also by a) raw byte
254     position in NKSP source code string and b) length of that code block in
255     bytes (along to the already existing code block tracking by line/column);
256     and added appropriate new members to public C++ API classes like
257     'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
258 schoenebeck 3733 - NKSP language: Added support for 'patch' variable qualifier (capture their
259     locations and allow replacement of their assignment expression via VM C++
260     API).
261 schoenebeck 3551
262 schoenebeck 3550 * test cases:
263 schoenebeck 3548 - Fixed compiler errors in test cases.
264     - Updated README for how to compile & run test cases.
265     - Updated test case
266     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
267     expected behaviour of the Mutex class implementation (recursive
268     mutex type).
269 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
270     functions.
271 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
272 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
273     int_to_real(), real(), real_to_int() and int(), as well as for the
274     plus, minus and negate language operators.
275 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
276     'final' operator usage cases.
277     - Added NKSP test cases for (floating point tolerance aware) real number
278     equalness / unequalness comparison.
279 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
280     initialization of arrays.
281 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
282     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
283     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
284 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
285 schoenebeck 3693 - Added NKSP test cases for core built-in variables.
286 schoenebeck 3727 - Added thorough NKSP test cases for variable declarations.
287 schoenebeck 3548
288 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
289     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
290     behaviour for start_level_mid.
291 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
292     level (see discussion "GigaStudio LFO compatibility" on mailing list
293     from 2019-09-26 for details).
294 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
295     see discussion "GigaStudio LFO compatibility" on mailing list from
296     2019-09-26 for details).
297 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
298     either sine [default], triangle, saw or square).
299     - Format extension: Added support for LFO phase displacement (0��..360��).
300     - Format extension: Added support for flipping LFO polarity on LFO 3
301     (in the original gig format this was only available for LFO 1 and LFO 2).
302 schoenebeck 3646 - Format extension: Support for additional filter types:
303     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
304     bandreject 2-pole.
305 schoenebeck 3719 - Fixd potential crash with polynomial interpolator and max. pitch.
306 schoenebeck 3721 - If minimum cutoff is defined, remap cutoff controller CC values to really
307     span the entire possible cutoff range (and avoiding a dead controller
308     zone).
309 schoenebeck 3733 - Implemented support for loading instrument scripts with 'patch' variables
310     (by patching these script variables with potentially overridden ones by
311     gig Instrument).
312 schoenebeck 3611
313 persson 3593 * SFZ format engine:
314     - Fixed support for regions with loccN/hiccN conditions on more than one
315     MIDI controller.
316    
317 schoenebeck 3612 * Benchmarks:
318     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
319     algorithm (since result of 2nd run was not accumulated).
320     - Added benchmark for saw wave (benchmarks/saw.cpp).
321     - Added benchmark for sine wave (benchmarks/sine.cpp).
322     - Added benchmark for square wave (benchmarks/square.cpp).
323     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
324     which are large enough on modern systems.
325    
326 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
327 schoenebeck 3381
328     * Real-time instrument scripts:
329     - Fixed behavior of built-in NKSP functions change_sustain(),
330     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
331     and change_cutoff_release().
332    
333 schoenebeck 3444 * general changes:
334     - Only play release trigger samples on sustain pedal up if this behaviour
335     was explicitly requested by the instrument (otherwise only on note-off).
336 persson 3455 - Fixed compiler warnings.
337     - Fixed compilation error when cross-compiling to Mac.
338 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
339     (see bug #169).
340     - LSCP doc: Be more clear describing the two distinct approaches
341     of using external vs. internal effects (see bug #169).
342 schoenebeck 3514 - "optional" class: Fixed comparison operators.
343 schoenebeck 3444
344 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
345     - Format extension: If requested by instrument then don't play release
346     trigger sample on note-off events.
347    
348 schoenebeck 3487 * SFZ format engine:
349     - Fixed memory leak when releasing samples
350     (fixes bug #307, patch by Jacek Roszkowski)
351 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
352     (fixes bug #308, patch by Jacek Roszkowski).
353 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
354     (fixes bug #310, patch by Jacek Roszkowski).
355 schoenebeck 3487
356 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
357 persson 2837
358 persson 2856 * SFZ format engine:
359     - added support for <global>, <master> and #define (patch by Alby M)
360 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
361     - Added support for sfz extension opcode 'script' which may be used to
362     load real-time instrument script file (NKSP script language).
363 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
364 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
365 persson 3291 - sfz parser: allow missing space between header and opcode
366 persson 2856
367 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
368 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
369     cutoff settings.
370 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
371     all if an up-pitch of more than 40 semi tones was requested (I don't
372     think there is any stock gig sound that requires this behavior to
373     resemble its original sound).
374 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
375     be aborted (as LinuxSampler extension to the original GigaStudio 4
376     format).
377 schoenebeck 3072
378 persson 2837 * general changes:
379     - fixed printf type errors (mostly in debug messages)
380 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
381 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
382     allowing to sort data efficiently in real-time safe manner.
383     - RTList class: added methods for moving/inserting elements to arbitrary
384     position within a list.
385     - RTList class: added method fromPtr() for creating an Iterator object from
386     a raw element pointer.
387     - Attempt to partly fix resetting engine channels vs. resetting engine, an
388     overall cleanup of the Reset*(), ConnectAudioDevice(),
389     DisconnectAudioDevice() API methods would still be desirable though,
390     because the current situation is still inconsistent and error prone.
391 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
392     being directly assigned to a keyboard key. This allows more fine graded
393     processing of voices, which is i.e. required for certain instrument
394     script features.
395 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
396     (CC #64) events.
397     - Fix: Release trigger voices can now also distinguish correctly between
398     note-off and sustain pedal up events.
399 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
400     (while slow rate of crossfade smoother is preserved) to allow quick
401     volume and pan changes by instrument scripts for instance.
402 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
403     properly and thus were ignored for certain uses.
404 schoenebeck 3018 - Added new C++ API method
405     VirtualMidiDevice::SendChannelPressureToSampler().
406 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
407     sub threads is 16-byte aligned
408 schoenebeck 3054 - fixed numerous compiler warnings
409 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
410 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
411     fixes potential undefined behavior.
412 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
413     have a valid sample mapped (fixes bug #252).
414     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
415 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
416     subsequent optional argument due to glibc's implementation oddity
417     which expects a "=" sign, but no space between them.
418 persson 2837
419 schoenebeck 2866 * packaging changes:
420     - removed unnecessary dependency to libuuid
421     (originated by libgig's usage of it)
422 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
423     auto detect whether it (sh/c)ould output its messages in color.
424 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
425     substitution variable.
426     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
427 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
428     linuxsampler with instruments DB support.
429 schoenebeck 2866
430 schoenebeck 2871 * Real-time instrument scripts:
431     - Implemented scheduler for delayed MIDI events and for suspended scripts.
432     - Built-in script function "wait()": implemented support for function's
433     "duration-us" argument, thus scripts using this function are now
434     correctly resumed after the requested amount of microseconds.
435     - Built-in script function "play_note()": implemented support for
436     function's "duration-us" argument, thus notes triggered with this
437     argument are now correctly released after the requested amount of
438     microseconds.
439     - Fix: script events were not cleared when engine channel was reset,
440     potentially causing undefined behavior.
441     - Fixed crash which happened when trying to reference an undeclared
442     variable.
443 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
444     special value -1 for "duration-us" argument, which will cause the
445     triggered note to be released once the original note was released.
446 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
447     - Added new API method ScriptVM::syntaxHighlighting() which provides
448     a convenient syntax highlighting backend for external instrument
449     script editor applications.
450 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
451     - Extended parser issues to provide not only first line and first
452     column, but also last line and last column of issue (thus marking
453     the precise span of the issue within the source code).
454 schoenebeck 2902 - Reload script automatically after being modified by an instrument
455     editor.
456 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
457     like "on note end on".
458 schoenebeck 2931 - Implemented built-in script function "change_vol()".
459     - Implemented built-in script function "change_tune()".

462     - Implemented built-in script function "change_reso()".
463     - Implemented built-in script function "event_status()".
464     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
465     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
466     "event_status()" function.
467     - NKSP language: Added support for bitwise operators ".or.", ".and."
468     and ".not.".
469     - NKSP language scanner: Fixed IDs matching to require at least one
470     character (i.e. when matching function names or variable names).
471     - NKSP language scanner: disabled unusued rules.
472 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
473     be distinguished engine internally from "real" MIDI note on/off
474     events in order to avoid misbehaviors like hanging notes.
475 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
476     - Implemented built-in script variable "$NKSP_REAL_TIMER".
477     - Implemented built-in script variable "$NKSP_PERF_TIMER".
478     - Implemented built-in script variable "$ENGINE_UPTIME".
479 schoenebeck 2945 - Implemented built-in script function "inc()".
480     - Implemented built-in script function "dec()".
481     - NKSP language fix: division expressions were evaluated too often.
482     - NKSP language fix: string concatenation operator was right
483     associative instead of left (to right).
484 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
485     (i.e. "if end if").
486 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
487     - Implemented built-in script variable "$NI_CALLBACK_ID".
488     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
489     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
490     - Added support for read-only built-in variables (respectively

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

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

594     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
595     - Added built-in constant $CALLBACK_STATUS_QUEUE.
596     - Added built-in constant $CALLBACK_STATUS_RUNNING.
597 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
598     "change_decay()" and "change_release()" to i.e. allow passing 2000000
599     for doubling the respective time.
600 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
601     to a lexer start condition stack underrun.
602     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
603     USE_CODE_IF_NOT() preprocessor statements.
604 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
605     can be set to disable all subsequent built-in "message()" function calls
606     on preprocessor level.
607 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
608 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
609     to avoid the editor app to crash on ill-formed text input.
610 schoenebeck 3335 - Added built-in script function "change_pan_time()".
611     - Added built-in script function "change_pan_curve()".

619 schoenebeck 3050 * Instruments DB:
620     - Fixed memory access bug of general DB access code which lead to
621     undefined behavior.
622 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
623     - The instrument DB path of linuxsampler's --create-instruments-db argument
624     is now optional, if it is missing, then a default location is used.
625 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
626     - Added support for scanning Sound Font (.sf2) files.
627 schoenebeck 3101 - Fixed undefined DB transaction behavior.

663     - support building with older jack versions
664     - support building with spaces in vst sdk path
665 persson 2519 - enabled automake 'subdir-objects' option and moved external

667     in order to get rid of warnings from automake 1.14
668 persson 2382
669 persson 2086 * general changes:
670 iliev 2012 - Refactoring: moved the independent code from
671     the Gigasampler format engine to base classes
672 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
673     respective profiling code is currently broken
674 schoenebeck 2053 - Introduced support for optional environment variable
675     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
676     where the sampler shall look for instrument editor plugins
677     (patch by Luis Garrido, slightly modified).
678 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
679     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
680     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
681     note (in this implementation of the sampler its simply hard routed to
682     the 1st effect send of the sampler channel, no matter what the actual
683     effect type is)
684     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
685     note (in this implementation of the sampler its simply hard routed to
686     the 2nd effect send of the sampler channel, no matter what the actual
687     effect type is)
688 schoenebeck 2124 - implemented support for internal LADSPA effects
689 schoenebeck 2140 - raised limit of program change queue from 100 to 512
690     (as suggested by Alex Stone)
691 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
692 iliev 2296 - experimental support for per voice equalization
693 iliev 2306 - added command line option --exec-after-init
694 schoenebeck 2330 - Introduced new C++ API method:
695     EngineChannel::InstrumentFileName(int index)
696     allowing to retrieve the whole list of files used for the loaded
697     instrument on an engine channel (a.k.a. part). Some GigaStudio
698     instruments for example are splitted over several files like
699     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
700 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
701     - Added new C++ API method Sampler::GetGlobalMaxStreams().
702     - Added new C++ API method Sampler::SetGlobalMaxVoices().
703     - Added new C++ API method Sampler::SetGlobalMaxStreams().
704 schoenebeck 2377 - Various "const" and "restrict" optimizations.
705 persson 2382 - all engines: add pan CC value to instrument pan parameter before
706     applying panning, instead of using two separate pan functions in
707     series (#182)
708 persson 2427 - added a lock guard class for exception safe mutex handling and
709     used it everywhere appropriate
710 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
711     - Exposed scale tuning to C++ API (along to the already existing standard
712     SysEx way).
713 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
714     and broken for ppc64. (Seq_cst loads and stores are actually not
715     used in LS, so the bug wasn't noticable.)
716     - lsatomic.h: added ARMv7 support
717 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
718     added various new C++ methods for this new feature / design change, old
719     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
720     as deprecated but are still there and should provide full behavior
721     backward compatibility).
722     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
723     unsafe and caused compilation error with clang 2.x).
724 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
725 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
726     sampler from the command line by providing LSCP aware features.
727 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
728     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
729     - VirtualMidiDevice: Added support for pitch bend.
730 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
731     polyphonic key pressure events (so far polyphonic pressure was not
732     supported at all, and channel pressure was rerouted as CC128 but not
733     used so far).
734 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
735     code is shared by all sampler engine implemementations, however only the
736     gig file format currently provides support for storing instrument scripts
737     (as LinuxSampler extension to the original GigaStudio 4 format).

1139     instrument was completely reloaded again.
1140 persson 2277 - fixed handling of rapid bank select and program change messages

1164 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1165     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1166     practically irrelevant, however it caused problems with the new LSCP
1167     shell's auto completion feature).
1168 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1169     after each other (fixes #231).

1222 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1223     a pointer to the launched InstrumentEditor object
1224 schoenebeck 1876 - added optional 3rd party user data parameter for following

1294     if no DB is present it automatically creates the .linuxsampler subdir
1295     and then creates an empty DB
1296 persson 1943 - fixed recursive import, which was broken on Windows
1297 iliev 1603
1298 persson 1644 * Gigasampler format engine:

1310     connected to the respective MIDI input port the SysEx message arrived
1311     on)
1312 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1313     sometimes wrongly killed in the same buffer, causing no sound to
1314     be played
1315 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1316     which is usally used to switch a part between chromatic sounds and
1317     drumkit sounds (as opposed to their common default setting of MIDI
1318     part 10 being a drumkit part and all other ones chromatic parts), in
1319     LS however one can switch between the first 16 MIDI instrument maps
1320     defined for the sampler
1321 persson 1764 - made it possible to create multiple sample channels even if the

1328     e.g. when a sample was added while playing (#82)
1329 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1330     same time stamp as the voice's note-on event and occured both in the
1331     same audio fragment cycle (fixes bug #112)
1332 persson 1858 - added support for the "fine tune" and "pitch bend range"
1333     instrument-level gig parameters
1334     - fixed minor artifacts in pitch bend handling
1335 schoenebeck 1860 - added support for GS Reset SysEx message
1336 persson 1862 - allow gig files to use unlimited downward pitch shifting
1337     - added a limit check for upward pitch shifting
1338 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1339     note was silent
1340 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1341     same time a new instrument was loading
1342 persson 1644
1343 schoenebeck 1687 * LSCP server:
1344     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

1346     Note-On and Note-Off events are sent via this LSCP event)
1347 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1348     react on MIDI data arriving on certain MIDI input devices (so far only
1349     Note-On and Note-Off events are sent via this LSCP event)
1350 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1351     SET DB_INSTRUMENT FILE_PATH
1352 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1353     frontends to send MIDI messages to specific sampler channel
1354     - added two additional fields to GET FILE INSTRUMENT INFO command -
1355     KEY_BINDINGS and KEYSWITCH_BINDINGS
1356 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1357     was incorrect
1358 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1359 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1360     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1361     be triggered respectively
1362     - added new LSCP command "SET STREAMS" to globally alter the maximum
1363     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1364     which will be triggered respectively
1365 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1366     a gigedit file dialog is opened)

1396 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1397     Windows

1400 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1401 schoenebeck 1454
1402     * packaging changes:
1403     - added autoconf checks for pthread library
1404     - added autoconf check for pthread bug found on certain NPTL-enabled
1405     glibc versions (see Gentoo bug report #194076)
1406 senoner 1502 - added autoconf checks for MS Windows
1407 schoenebeck 1454
1408 persson 1455 * general changes:
1409     - bugfix: the thread used by an editor plugin didn't die when the
1410     editor closed
1411 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1412     out all the space. operator--() did not apply size_mask after
1413     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1414     order to avoid problems with the _NonVolatileReader functions.
1415     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1416     GetWriteSpace(). Since this function is currently only used in
1417     the stream's qsort() compare function, it didn't trigger any
1418     bugs.
1419     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1420     24bit mode too. Faster method to read 24bit words on little
1421     endian machines (x86): replaced 3 byte reads + shifts with a 1
1422     unaligned 32bit read and shift
1423     - experimental support for MS Windows (MIDI input via MME, AUDIO
1424     output via ASIO)
1425     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1426 iliev 1541 - support for monitoring the total number of active disk streams
1427     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1428     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1429 persson 1455
1430 senoner 1500 * AUDIO driver:
1431 persson 1534 - added Windows ASIO low latency audio driver
1432 senoner 1500
1433 senoner 1485 * MIDI driver:
1434 schoenebeck 1495 - added MME Windows MIDI driver
1435 senoner 1485
1436 schoenebeck 1471 * LSCP server:
1437     - added support for Windows style path / filenames, however with
1438     forward slash path separators instead of backslash
1439     (i.e. "C:/foo/bar.gig")
1440 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1441     apostrophes as well
1442 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1443     "LIST FILE INSTRUMENTS <file>" and
1444     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1445     about an arbitrary instrument file on the system where the sampler is
1446     running on
1447 schoenebeck 1471
1448 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1449 schoenebeck 947
1450 schoenebeck 1065 * packaging changes:
1451 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1452     API header files anymore
1453 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1454     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1455 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1456     capable to execute our autoconf environment, thus no need anymore
1457     to maintain the compile time configuration file (osx/version.h) for
1458     OSX manually (patch by Toshi Nagata)
1459 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1460     parameters
1461 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1462     C++ API header files, all implementation internal global definitions
1463     are now in global_private.h
1464     - atomic.h is not exposed to the C++ API anymore
1465     - no need to include config.h anymore for using LS's API header files
1466     - fixed warnings in API doc generation
1467 schoenebeck 1065
1468 schoenebeck 947 * general changes:
1469     - replaced the old, confusing MIDI program change mechanism by a
1470     flexible MIDI instrument mapper which allows to map arbitrary
1471 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1472 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1473     loaded on the respective channel when such MIDI program change
1474     messages arrive, beside that, each entry allows to define a life-time
1475     strategy for the instrument, so the user can define whether the
1476     instrument should i.e. be permanently loaded (to be able to switch
1477     quickly among sounds) or i.e. loaded just on demand when the
1478     respective program change arrives (to safe RAM space), as well as a
1479     global volume factor for each entry, so the user can adjust the volume
1480     dynamic of his mapped instrument collection without having to modify
1481 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1482     MIDI instrument maps and assign each sampler channel individually
1483     a certain map, so that i.e. separation of normal instruments and
1484     drumkits is possible
1485 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1486     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1487 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1488     due to a constant size RingBuffer FIFO which is now replaced by a
1489     dynamic (unlimited) size std::list FIFO
1490 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1491     output channels for being processed by external effect processors
1492     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1493     controllers
1494 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1495 iliev 1130 - Implemented new, improved notification system
1496 schoenebeck 1149 - fixed compilation errors regarding OSX
1497     (patch by Toshi Nagata)
1498 iliev 1161 - implemented instruments database
1499 iliev 1345 - added support for escape sequences to the instruments database
1500 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1501     within the sampler's process (by using instrument editor plugins),
1502     you'll notice the new "Registered instrument editors:" message on
1503 schoenebeck 1407 startup, added a new LSCP command:
1504     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1505 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1506     given sampler channel, the plugin path can be overridden at compile
1507     time with ./configure --enable-plugin-dir=/some/dir
1508 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1509     in the sampler's process to safely edit instruments while playing
1510     without a crash (hopefully) by either suspending single regions
1511     wherever possible or if unavoidable whole engine(s)
1512 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1513     policy and priority on thread level, set a minimum stack size for
1514     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1515     threads simply inherited properties of starting thread instead of
1516     setting their own policy and priority
1517 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1518     main process did not wait for the stack trace process to finish
1519     its output
1520 persson 1248 - fixed some minor memory leaks
1521 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1522     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1523 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1524     register, to avoid relocations in the text segment at runtime)
1525 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1526 schoenebeck 947
1527     * MIDI driver:
1528     - dispatch bank select (MSB and LSB) messages
1529    
1530 schoenebeck 1049 * audio driver:
1531     - the ALSA audio output driver parameters now reflect the correct
1532     parameter value ranges for the respective selected sound card
1533     (patch by Till Wimmer, a bit fixed and extended)
1534    
1535 persson 951 * Gigasampler format engine:
1536     - if a filter is used and EG2 finishes before EG1, let the voice
1537     die when EG2 has finished (this fixes a problem with clicks and
1538     voice starvation for some gigs)
1539 persson 1038 - playback is no longer disabled during instrument loading
1540     - all notes playing on a channel that changes its instrument keep
1541     playing with the old instrument until they get a note off
1542     command
1543 persson 1039 - EG fix: a release value of zero could cause noises or crash
1544 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1545 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1546     above max sustain level, which means that there is a decay phase
1547     even if sustain is 100%
1548 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1549     noises or crashes
1550 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1551 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1552     supplied to the configure script (fixes #46)
1553 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1554     instead of a fix value
1555 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1556     127 (solo mode) only kill voices if the respective mode really
1557     changed
1558 persson 951
1559 schoenebeck 1244 * LSCP server:
1560     - fixed compile time error for old Bison versions
1561     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1562 schoenebeck 1245 - parser now supports extended ASCII character set
1563     (up to ASCII code 255, i.e. includes now umlauts and accents)
1564     - filename arguments in LSCP commands now allow to use escape
1565     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1566     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1567     code value like \xf2) (fixes bug #24)
1568 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1569     least one of their text-based parameters (i.e. name, description):
1570     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1571     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1572     "SET DB_INSTRUMENT_DIRECTORY NAME",
1573     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1574     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1575     "FIND DB_INSTRUMENT_DIRECTORIES"
1576 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1577     occured, the unexpected character and the actually expected, possible
1578     character(s), the latter only if less than 5 possibilities)
1579 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1580     settings
1581 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1582     of strings were treated as being one string containing commas
1583     (fixes #57)
1584 schoenebeck 1244
1585 iliev 959 * Bug fixes:
1586     - fixed crash occurring on certain LSCP scripts (Bug 39)
1587 persson 1038 - another thread safety fix for lscp "load engine" and "set
1588     channel audio output device"
1589 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1590     on a sampler channel with connected MIDI device
1591 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1592     device connected to a sampler channel to number less then or equal
1593     to the index of the port to which the sampler channel is connected.
1594 iliev 1296 - The previous bindings were not been disconnected when altering
1595     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1596     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1597 iliev 1297 - The active stream/voice count statistic was incorrect.
1598 iliev 1298 - notification events were not been sent for some sampler
1599     channel changes
1600 iliev 1305 - added default min and max values to restrict the number of allowed
1601     audio output channels and MIDI input ports
1602 iliev 1306 - the connection to the PCM interface is now closed when destroying
1603     an audio output device
1604 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1605 iliev 959
1606 schoenebeck 1221 * test cases:
1607     - updated and fixed (haven't been touched in a while)
1608    
1609 schoenebeck 937 Version 0.4.0 (24 November 2006)
1610 persson 696
1611 schoenebeck 697 * packaging changes:
1612 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1613     to post-(un)install steps; added devel package for liblinuxsampler;
1614     to linuxsampler.spec (RPM)
1615 schoenebeck 697 - install necessary development header files for allowing 3rd party
1616     applications to link against liblinuxsampler
1617     - liblinuxsampler's API documentation can be generated with 'make docs'
1618     (Doxygen required)
1619 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1620     implementation (currently either an integer math solution or a
1621     di-harmonic approximation), automatic detection can be overriden
1622     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1623     configure script argument though (mandatory for cross-compilation)
1624 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1625     provided some on his own (as CXXFLAGS)
1626 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1627     messages
1628 schoenebeck 852 - added compile time options to allow disabling the various audio and
1629     MIDI drivers
1630 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1631     (patch by Ebrahim Mayat)
1632 schoenebeck 697
1633 persson 696 * Gigasampler format engine:
1634 schoenebeck 738 - extensive synthesis optimization
1635     (reimplementation of EGs and LFO(s), removed synthesis parameter
1636     prerendering and the synthesis parameter matrix in general, splitting
1637     each audio fragment into subfragments now where each subfragment uses
1638 persson 830 constant pitch and filter coefficients. The volume coefficient is
1639     linearly interpolated inside a subfragment, unless
1640     --disable-interpolate-volume is set.)
1641 persson 696 - fine tuning of the EG modulation parameters
1642 persson 729 - improved filter cutoff calculation by adding support for the
1643     following gig parameters: Cutoff freq (used when no cutoff
1644     controller is defined), Control invert, Minimum cutoff, Velocity
1645 persson 791 curve and Velocity range. The keyboard tracking now scales
1646     cutoff frequency instead of resonance.
1647 persson 877 - added support for gig parameter Resonance.
1648 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1649 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1650     which can be overridden with --enable-global-attenuation
1651 persson 783 - EG fixes: made the length of "attack hold" stage more
1652     accurate. Release stage can now start before attack stage
1653 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1654     time now has a minimal value to prevent clicks.
1655 persson 799 - fixed pitch changes larger than one octave
1656 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1657     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1658     all modes can be altered via standard GM messages, that is CC5 for
1659     altering portamento time, CC65 for enabling / disabling portamento
1660     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1661 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1662     parameter) and crossfade
1663 persson 831 - added support for the "attenuation controller threshold" gig
1664     parameter
1665 persson 832 - added smoothing of volume changes caused by control change
1666     messages
1667 persson 865 - sample loop parameters are now taken from the DimensionRegion
1668     instead of the wave chunk
1669     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1670     not equal to a power of two
1671 persson 877 - reimplementation of the filter algorithm. The new filter is more
1672     accurate and supports all gig filter types, including bandreject
1673     and lowpass turbo.
1674 persson 903 - real support for 24 bit samples - samples are not truncated to
1675     16 bits anymore
1676     - support for aftertouch (channel pressure, not polyphonic
1677     aftertouch)
1678 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1679     amplifying from 0)
1680 persson 696
1681 schoenebeck 711 * LSCP server:
1682     - fixed application exit on broken pipe error (fixes bug #20)
1683 iliev 793 - fixed the notification messages delay due to lack of
1684     network activity (fixes bug #26)
1685 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1686     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1687 schoenebeck 711
1688 schoenebeck 838 * audio driver:
1689     - added aRts audio output driver (by no means RT safe)
1690    
1691 schoenebeck 775 * MIDI driver:
1692     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1693     messages several times instead of once
1694 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1695     for events (i.e. for offline rendering based MIDI drivers)
1696 persson 922 - added checks for bad MIDI data
1697 schoenebeck 775
1698 schoenebeck 900 * linuxsampler application:
1699     - show available sampler engine types on startup
1700    
1701 schoenebeck 705 * general changes:
1702     - support for muting sampler channels and solo mode of the same, two new
1703     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1704     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1705     introduced for this, the behavior is the same like on a mixer console
1706 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1707     --enable-process-muted-channels which can be used to enable the
1708     processing of muted channels.
1709 iliev 777 - support for sostenuto pedal
1710 iliev 779 - support for monitoring the total number of active voices
1711 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1712     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1713 persson 835 - fixed some memory management errors
1714 persson 841 - fixed some concurrency problems that could lead to crashes when
1715     LSCP commands were executed
1716 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1717     sampler channel (fixes bug #36)
1718 schoenebeck 705
1719 schoenebeck 692 Version 0.3.3 (15 July 2005)
1720 schoenebeck 686
1721     * packaging changes:
1722     - fixed compilation with gcc 4.0
1723    
1724 schoenebeck 687 * Gigasampler format engine:
1725     - LFO preprocessing was performed even though the respective LFO was
1726     disabled by the instrument patch (minor efficiency fix)
1727 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1728     for volume ramp downs in the same fragment (needed for current voice
1729     stealing implementation) then simply inform the user with a warning
1730     about possible click sounds and reduce the volume ramp down
1731     appropriately instead of cancelling the audio device connection
1732 schoenebeck 687
1733 schoenebeck 677 Version 0.3.2 (24 June 2005)
1734 schoenebeck 609
1735     * packaging changes:
1736     - updated autotools build files to compile on OS X
1737     (conditional compilation of CoreMIDI and MidiShare drivers)
1738 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1739     './configure --disable-asm' (definitely not recommended)
1740 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1741     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1742     (due to 'dist-bzip2' automake option)
1743 schoenebeck 649
1744     * Gigasampler format engine:
1745     - support for the gig parameters for "release velocity response" curves
1746     - fine tuning of the EGADSR envelope
1747     - volume of release triggered samples now depends on note-on velocity,
1748     note length and gig parameter "release trigger decay" instead of
1749     note-off velocity.
1750 schoenebeck 663 - revised voice stealing
1751     (fixes crash and endless loop caused by voice stealing)
1752 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1753 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1754     instead of when the respective voice is actually launched
1755     (fixes undefined behavior if stolen voices belonged to a key group -
1756     this case was followed by a "killed voice survived" error message)
1757 schoenebeck 669 - fixed minor issue with null/silence samples
1758     (those stole voices even though they don't need a voice at all which
1759     resulted in "voice stealing didn't work out" messages)
1760 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1761     instrument or audio output device change
1762 schoenebeck 654
1763 schoenebeck 620 * LSCP server:
1764 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1765 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1766 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1767 schoenebeck 609
1768 schoenebeck 668 * linuxsampler application:
1769     - added command line parameters --lscp-addr and --lscp-port to override
