Implemented support for compressed RPN/NRPN message sequences:

* Allow processing MIDI data entry messages without having to be
  preceded strictly always by RPN/NRPN parameter selection messages
  prior to each value change (i.e. data entry CC).

* Bumped version (2.1.1.svn33).

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

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

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

439 schoenebeck 2945 - Implemented built-in script function "inc()".
440     - Implemented built-in script function "dec()".
441     - NKSP language fix: division expressions were evaluated too often.
442     - NKSP language fix: string concatenation operator was right
443     associative instead of left (to right).
444 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
445     (i.e. "if end if").
446 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
447     - Implemented built-in script variable "$NI_CALLBACK_ID".
448     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
449     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

453     - Added built-in script constant "$NI_CB_TYPE_NOTE".
454     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

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

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

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

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

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

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

1095     after MIDI/audio device creation failure
1096 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1099     instrument was completely reloaded again.
1100 persson 2277 - fixed handling of rapid bank select and program change messages
1101     sent to the same sampler channel (patch from the Open Octave

1124 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1125     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1126     practically irrelevant, however it caused problems with the new LSCP
1127     shell's auto completion feature).
1128 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1129     after each other (fixes #231).

1181     stacktrace mechanism seems to be broken on most systems at the moment)
1182 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1183     a pointer to the launched InstrumentEditor object
1184 schoenebeck 1876 - added optional 3rd party user data parameter for following

1248     instrument database compilable
1249 schoenebeck 1930 - added instrument database support on Windows
1250     works with both standalone mode and VST plugin.
1251     the instruments DB file is located in
1252     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1253     databases for each windows user
1254     if no DB is present it automatically creates the .linuxsampler subdir
1255     and then creates an empty DB
1256 persson 1943 - fixed recursive import, which was broken on Windows
1257 iliev 1603
1258 persson 1644 * Gigasampler format engine:

1267 schoenebeck 1724 - added support for GM global device volume SysEx message
1268 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1269     whole sampler [default] or only to the sampler channels that are
1270     connected to the respective MIDI input port the SysEx message arrived
1271     on)
1272 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1273     sometimes wrongly killed in the same buffer, causing no sound to
1274     be played
1275 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1276     which is usally used to switch a part between chromatic sounds and
1277     drumkit sounds (as opposed to their common default setting of MIDI
1278     part 10 being a drumkit part and all other ones chromatic parts), in
1279     LS however one can switch between the first 16 MIDI instrument maps
1280     defined for the sampler
1281 persson 1764 - made it possible to create multiple sample channels even if the
1282     audio thread isn't running
1283 persson 1844 - fixed crash when removing channel with active voices (#116)

1285     un-cache the respective sample if it's really not used by any
1286     sampler engine anymore
1287     - re-cache samples in case they were changed by an instrument editor,
1288     e.g. when a sample was added while playing (#82)
1289 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1290     same time stamp as the voice's note-on event and occured both in the
1291     same audio fragment cycle (fixes bug #112)
1292 persson 1858 - added support for the "fine tune" and "pitch bend range"
1293     instrument-level gig parameters
1294     - fixed minor artifacts in pitch bend handling
1295 schoenebeck 1860 - added support for GS Reset SysEx message
1296 persson 1862 - allow gig files to use unlimited downward pitch shifting
1297     - added a limit check for upward pitch shifting
1298 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1299     note was silent
1300 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1301     same time a new instrument was loading
1302 persson 1644
1303 schoenebeck 1687 * LSCP server:
1304     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1305     react on MIDI data arriving on certain sampler channels (so far only
1306     Note-On and Note-Off events are sent via this LSCP event)
1307 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1308     react on MIDI data arriving on certain MIDI input devices (so far only
1309     Note-On and Note-Off events are sent via this LSCP event)
1310 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1311     SET DB_INSTRUMENT FILE_PATH
1312 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1313     frontends to send MIDI messages to specific sampler channel
1314     - added two additional fields to GET FILE INSTRUMENT INFO command -
1315     KEY_BINDINGS and KEYSWITCH_BINDINGS
1316 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1317     was incorrect
1318 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1319 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1320     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1321     be triggered respectively
1322     - added new LSCP command "SET STREAMS" to globally alter the maximum
1323     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1324     which will be triggered respectively
1325 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1326     a gigedit file dialog is opened)
1327 iliev 1848 - close all connections when LSCPServer is deleted
1328 iliev 1882 - hard close of all sockets on exit

1367 schoenebeck 1454
1368 persson 1455 * general changes:
1369     - bugfix: the thread used by an editor plugin didn't die when the
1370     editor closed
1371 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1372     out all the space. operator--() did not apply size_mask after
1373     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1374     order to avoid problems with the _NonVolatileReader functions.
1375     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1376     GetWriteSpace(). Since this function is currently only used in
1377     the stream's qsort() compare function, it didn't trigger any
1378     bugs.
1379     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1380     24bit mode too. Faster method to read 24bit words on little
1381     endian machines (x86): replaced 3 byte reads + shifts with a 1
1382     unaligned 32bit read and shift
1383     - experimental support for MS Windows (MIDI input via MME, AUDIO
1384     output via ASIO)
1385     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1386 iliev 1541 - support for monitoring the total number of active disk streams

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