* Fixed rare crash when switching between instruments that had instrument
  scripts loaded.

* Bumped version (2.1.1.svn61).

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 3763 - Added global backtraceAsString() function for debugging purposes
57     (POSIX systems only, no Windows implementation yet).
58 schoenebeck 3764 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59     nameOfCaller() and setNameOfCaller().
60     - configure: Always check for availability of pthread_testcancel() and use
61     it if so (previously it was only used if explicitly enabled by configure
62     option).
63     - Thread class: raise compiler warning if pthread_testcancel() is not
64     available, because it can lead to deadlocks.
65 schoenebeck 3765 - Mutex class: Implemented optional bug detection and deadlock debugging
66     features.
67 schoenebeck 3768 - Ref<> class is now thread safe (as lock-free and wait-free
68     implementation).
69 schoenebeck 3787 - Fixed compilation error with Bison >= 3.6.0.
70 schoenebeck 3802 - Fixed rare crash when switching between instruments that had instrument
71     scripts loaded.
72 schoenebeck 3550
73 schoenebeck 3551 * Real-time instrument scripts:
74     - Added method ScriptVM::setExitResultEnabled() which allows to
75     explicitly enable the built-in exit() function to optionally accept
76     one function argument; the value of the passed exit() function
77     argument will then become available by calling
78     VMExecContext::exitResult() after script execution.
79 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
80 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
81     with a regular character (a-z or A-Z); starting them with a digit or
82     underscore is not allowed.
83     - NKSP parser fix: equal comparison operator "=" and not equal comparison
84     operator "#" must only accept integer operands.
85     - NKSP language: Implemented support for standard units like Hertz, seconds,
86     Bel including support for metric unit prefixes; so one can now e.g.
87     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
88     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
89     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
90     - NKSP language: Introduced "final" operator "!" which is specifically
91     intended for synthesis parameter values to denote that the synthesis
92     parameter value is intended to be the "final" value for that synthesis
93     parameter that should explicitly be used by the engine and thus causing
94     the sampler engine to ignore all other modulation sources for the same
95     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
96     variable or formula with this new "!" operator the expression is marked as
97     being "final".
98 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
99     and their potential metric prefix token.
100 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
101     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
102     - NKSP language: Added support for NKSP real number (floating point) script
103     variables (declare ~foo).
104     - NKSP language: Added support for NKSP real number (floating point) array
105     script variables (declare ?foo[]).
106     - Built-in script function "message()" accepts now real number argument as
107     well.
108     - Added built-in script function "real_to_int()" and its short hand form
109     "int()" for casting from real number to integer in NKSP scripts.
110     - Added built-in script function "int_to_real()" and its short hand form
111     "real()" for casting from integer to real number in NKSP scripts.
112 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
113     argument as well.
114 schoenebeck 3577 - Built-in script functions may have a different return type depending on
115     the arguments passed to the function.
116     - Built-in script function "abs()" optionally accepts and returns real
117     number.
118     - Built-in script functions "min()" and "max()" optionally accept real
119     number arguments and return real number as result in that case.
120 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
121     built-in functions (added methods VMFunction::returnUnitType() and
122     VMFunction::returnsFinal() for that purpose which must be implemented by
123     built-in function implementations).
124     - NKSP language: Allow metric unit prefixes of numeric scalar and array
125     variables to be changed freely at runtime (unlike unit types like Hz etc.
126     which are still sticky, parse-time features of variables which cannot be
127     changed at runtime for the intentional sake of determinism).
128     - NKSP language: 'final' values are prohibited for array variables for now
129     (attempt causes a parsers error).
130     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
131     conditions of runtime control structures like if(), while(), select()
132     (attempt causes a parser error).
133     - NKSP VM API: Allow built-in functions to perform their own, individual
134     parse time checks of arguments going to be passed to the function at
135     runtime (added method VMFunction::checkArgs() for that purpose).
136     - NKSP language: raise parser warning if only one operand of binary
137     operators (like logical 'or' comparison) contain a 'final' value (because
138     it would always yield in a 'final' result in such cases).
139     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
140     different metric unit prefixes, which will behave as expected (e.g.
141     result of expression '1000us < 2ms' is true).
142     - NKSP language: Allow adding values with different metric unit prefixes
143     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
144     - NKSP language: Allow subtracting values with different metric unit
145     prefixes (e.g. result of expression '1ms - 20us' is '980us').
146     - NKSP language: Allow multiplying with any metric unit prefixes
147     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
148     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
149     we don't have any considerable practical use for a term like '4s^2'
150     (hence any attempt multiplying two unit types still causes parser error).
151     - NKSP language: Allow dividing by any metric unit prefixes and allow
152     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
153     yields in unit free result '8'). So this is now a way to cast units away
154     e.g. for passing the result to other expressions, certain function calls
155     or variables which are not accepting any units (or that specific unit).
156     - NKSP language: integer arrays and real number arrays can now be converted
157     to strings (e.g. for dumping their content with message() calls for
158     script debugging purposes).
159     - NKSP language: expressions and variables with units are now correctly
160     casted to strings (e.g. with message() calls).
161     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
162     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
163     floating point tolerances into account.
164     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
165     VMScalarNumberExpr::evalCastReal().
166     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
167     'VMIntArrayExpr' and 'VMRealArrayExpr'.
168     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
169     unitFactor() (runtime) methods.
170     - Built-in function "exit()" supports now returning units and 'final'ness
171     for test cases.
172     - The following built-in functions support now units as well: "abs()",
173     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
174     "real_to_int()", "int()", "int_to_real()" and "real()".
175     - Built-in functions "array_equal()", "search()" and "sort()" support now
176     real number arrays (correctly) as well.
177     - Added individual parse time checks of arguments to be passed to built-in
178     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
179     "array_equal()" and "search()" specific for their individual purposes.
180 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
181     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
182     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
183     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
184     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
185     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
186     isScalarNumber() -> isNumber()).
187 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
188     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
189     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
190     as convenient methods for automatically converting values to expected
191     metric value basis.
192     - Built-in function "wait()" accepts now both integers and real numbers as
193     argument.
194 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
195     VMFunction::argType(vmint iArg) which was already superseded by its new
196     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
197     - NKSP parser: if wrong argument type was passed to a built-in function and
198     that built-in function accepts more than one data type for the argument,
199     then show all supported data types as parser error message.
200 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
201     unit type as well for its 3rd and 4th function arguments.
202     - The following built-in functions accept now real numbers as well for their
203     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
204     "change_attack()", "change_decay()", "change_release()",
205     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
206     "change_cutoff_sustain()", "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()", "fade_in()", "fade_out()", "change_play_pos()".
210     - Fixed built-in function "change_play_pos()" not having accepted metric
211     prefixes at all.
212 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
213     with unit type (for their 2nd argument) as if they were relative values
214     (that is as if they were passed without a unit type): "change_attack()",
215     "change_decay()", "change_release()", "change_cutoff_attack()",
216     "change_cutoff_decay()", "change_cutoff_release()".
217     - Fixed the following built-in functions having applied completely wrong
218     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
219     respective EGs being their modulation sink assume uint data type with
220     value range 0..1000 instead of 0.0..1.0.
221     - Added individual parse-time checks of function arguments for the following
222     built-in functions: "play_note()", "note_off()", "set_event_mark()",
223     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
224     "change_decay()", "change_release()", "change_cutoff_attack()",
225     "change_cutoff_decay()", "change_cutoff_release()",
226     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
227     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
228     "change_pan_time()".
229     - Don't abort function call if unit type was used and at the same time
230     'final' operator was omitted for the primary value argument of the
231     following built-in functions: "change_cutoff()", "change_attack()",
232     "change_decay()", "change_release()", "change_cutoff_attack()",
233     "change_cutoff_decay()", "change_cutoff_release()",
234     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
235     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
236     "change_pan_time()", instead imply 'final'ness at runtime and raise an
237     appropriate parser warning at parse time.
238 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
239     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
240     "cos()", "tan()", "asin()", "acos()", "atan()".
241     - Added built-in script real number constant "~NI_MATH_PI".
242     - Added built-in script real number constant "~NI_MATH_E".
243 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
244 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
245 schoenebeck 3690 - NKSP language: Added support for RPN event handler
246     ("on rpn ... end on" in instrument scripts).
247     - NKSP language: Added support for NRPN event handler
248     ("on nrpn ... end on" in instrument scripts).
249     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
250     may be read from the new RPN/NRPN script handlers to get the (N)RPN
251     parameter that had been changed and its new value.
252     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
253     which are identifying the new (N)RPN handlers as such at script runtime.
254 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
255     - Implemented built-in script function "set_nrpn()".
256 schoenebeck 3714 - Fix: built-in functions returning an array type were broken and caused a
257     crash when the built-in function's (supposed to be array) result value was
258     used by the script VM.
259 schoenebeck 3715 - Removed upper value constraint for 2nd argument of built-in functions
260     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
261     "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
262     "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
263     "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
264     the LFO frequency / resonance / cutoff frequency.
265 schoenebeck 3728 - Reduced code involved for parsing NKSP variable declarations by using 2
266     generalized grammar rules with optional components (i.e. optional value
267     assignment and optional variable qualifiers) instead of previous linear
268     combinations of grammar rules, which also fixes some edge case.
269 schoenebeck 3729 - NKSP language parser: track code block locations also by a) raw byte
270     position in NKSP source code string and b) length of that code block in
271     bytes (along to the already existing code block tracking by line/column);
272     and added appropriate new members to public C++ API classes like
273     'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
274 schoenebeck 3733 - NKSP language: Added support for 'patch' variable qualifier (capture their
275     locations and allow replacement of their assignment expression via VM C++
276     API).
277 schoenebeck 3742 - Fixed incorrect EG times if standard measuring unit was passed to built-in
278     functions "change_attack()", "change_decay()" or "change_release()".
279 schoenebeck 3744 - Fixed intermediate function result values never having reflected any
280     standard measuring unit type.
281 schoenebeck 3747 - Fixed re-entrant issue with function calls which caused wrong result
282     values if the same function was called multiple times in a term
283     (specifically if metric prefixes were used).
284 schoenebeck 3790 - NKSP language: Just throw a warning, not an error if an array variable of
285     size zero was declared.
286     - NKSP language: Allow omitting explicit array size on array variable
287     declaration if combined with immediate value assignment
288     (e.g. declare %foo[] := ( 1, 2, 3 ) ).
289 schoenebeck 3792 - NKSP language: emit warning if an array variable was declared with bigger
290     array size than amount of initial values been assigned, and initialize the
291     missing array elements with zero in this case.
292 schoenebeck 3551
293 schoenebeck 3550 * test cases:
294 schoenebeck 3548 - Fixed compiler errors in test cases.
295     - Updated README for how to compile & run test cases.
296     - Updated test case
297     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
298     expected behaviour of the Mutex class implementation (recursive
299     mutex type).
300 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
301     functions.
302 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
303 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
304     int_to_real(), real(), real_to_int() and int(), as well as for the
305     plus, minus and negate language operators.
306 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
307     'final' operator usage cases.
308     - Added NKSP test cases for (floating point tolerance aware) real number
309     equalness / unequalness comparison.
310 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
311     initialization of arrays.
312 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
313     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
314     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
315 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
316 schoenebeck 3693 - Added NKSP test cases for core built-in variables.
317 schoenebeck 3727 - Added thorough NKSP test cases for variable declarations.
318 schoenebeck 3548
319 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
320     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
321     behaviour for start_level_mid.
322 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
323     level (see discussion "GigaStudio LFO compatibility" on mailing list
324     from 2019-09-26 for details).
325 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
326     see discussion "GigaStudio LFO compatibility" on mailing list from
327     2019-09-26 for details).
328 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
329     either sine [default], triangle, saw or square).
330     - Format extension: Added support for LFO phase displacement (0��..360��).
331     - Format extension: Added support for flipping LFO polarity on LFO 3
332     (in the original gig format this was only available for LFO 1 and LFO 2).
333 schoenebeck 3646 - Format extension: Support for additional filter types:
334     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
335     bandreject 2-pole.
336 schoenebeck 3719 - Fixd potential crash with polynomial interpolator and max. pitch.
337 schoenebeck 3721 - If minimum cutoff is defined, remap cutoff controller CC values to really
338     span the entire possible cutoff range (and avoiding a dead controller
339     zone).
340 schoenebeck 3733 - Implemented support for loading instrument scripts with 'patch' variables
341     (by patching these script variables with potentially overridden ones by
342     gig Instrument).
343 schoenebeck 3611
344 persson 3593 * SFZ format engine:
345     - Fixed support for regions with loccN/hiccN conditions on more than one
346     MIDI controller.
347    
348 schoenebeck 3612 * Benchmarks:
349     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
350     algorithm (since result of 2nd run was not accumulated).
351     - Added benchmark for saw wave (benchmarks/saw.cpp).
352     - Added benchmark for sine wave (benchmarks/sine.cpp).
353     - Added benchmark for square wave (benchmarks/square.cpp).
354     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
355     which are large enough on modern systems.
356    
357 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
358 schoenebeck 3381
359     * Real-time instrument scripts:
360     - Fixed behavior of built-in NKSP functions change_sustain(),
361     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
362     and change_cutoff_release().
363    
364 schoenebeck 3444 * general changes:
365     - Only play release trigger samples on sustain pedal up if this behaviour
366     was explicitly requested by the instrument (otherwise only on note-off).
367 persson 3455 - Fixed compiler warnings.
368     - Fixed compilation error when cross-compiling to Mac.
369 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
370     (see bug #169).
371     - LSCP doc: Be more clear describing the two distinct approaches
372     of using external vs. internal effects (see bug #169).
373 schoenebeck 3514 - "optional" class: Fixed comparison operators.
374 schoenebeck 3444
375 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
376     - Format extension: If requested by instrument then don't play release
377     trigger sample on note-off events.
378    
379 schoenebeck 3487 * SFZ format engine:
380     - Fixed memory leak when releasing samples
381     (fixes bug #307, patch by Jacek Roszkowski)
382 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
383     (fixes bug #308, patch by Jacek Roszkowski).
384 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
385     (fixes bug #310, patch by Jacek Roszkowski).
386 schoenebeck 3487
387 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
388 persson 2837
389 persson 2856 * SFZ format engine:
390     - added support for <global>, <master> and #define (patch by Alby M)
391 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
392     - Added support for sfz extension opcode 'script' which may be used to
393     load real-time instrument script file (NKSP script language).
394 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
395 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
396 persson 3291 - sfz parser: allow missing space between header and opcode
397 persson 2856
398 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
399 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
400     cutoff settings.
401 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
402     all if an up-pitch of more than 40 semi tones was requested (I don't
403     think there is any stock gig sound that requires this behavior to
404     resemble its original sound).
405 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
406     be aborted (as LinuxSampler extension to the original GigaStudio 4
407     format).
408 schoenebeck 3072
409 persson 2837 * general changes:
410     - fixed printf type errors (mostly in debug messages)
411 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
412 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
413     allowing to sort data efficiently in real-time safe manner.
414     - RTList class: added methods for moving/inserting elements to arbitrary
415     position within a list.
416     - RTList class: added method fromPtr() for creating an Iterator object from
417     a raw element pointer.
418     - Attempt to partly fix resetting engine channels vs. resetting engine, an
419     overall cleanup of the Reset*(), ConnectAudioDevice(),
420     DisconnectAudioDevice() API methods would still be desirable though,
421     because the current situation is still inconsistent and error prone.
422 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
423     being directly assigned to a keyboard key. This allows more fine graded
424     processing of voices, which is i.e. required for certain instrument
425     script features.
426 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
427     (CC #64) events.
428     - Fix: Release trigger voices can now also distinguish correctly between
429     note-off and sustain pedal up events.
430 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
431     (while slow rate of crossfade smoother is preserved) to allow quick
432     volume and pan changes by instrument scripts for instance.
433 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
434     properly and thus were ignored for certain uses.
435 schoenebeck 3018 - Added new C++ API method
436     VirtualMidiDevice::SendChannelPressureToSampler().
437 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
438     sub threads is 16-byte aligned
439 schoenebeck 3054 - fixed numerous compiler warnings
440 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
441 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
442     fixes potential undefined behavior.
443 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
444     have a valid sample mapped (fixes bug #252).
445     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
446 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
447     subsequent optional argument due to glibc's implementation oddity
448     which expects a "=" sign, but no space between them.
449 persson 2837
450 schoenebeck 2866 * packaging changes:
451     - removed unnecessary dependency to libuuid
452     (originated by libgig's usage of it)
453 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
454     auto detect whether it (sh/c)ould output its messages in color.
455 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
456     substitution variable.
457     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
458 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
459     linuxsampler with instruments DB support.
460 schoenebeck 2866
461 schoenebeck 2871 * Real-time instrument scripts:
462     - Implemented scheduler for delayed MIDI events and for suspended scripts.
463     - Built-in script function "wait()": implemented support for function's
464     "duration-us" argument, thus scripts using this function are now
465     correctly resumed after the requested amount of microseconds.
466     - Built-in script function "play_note()": implemented support for
467     function's "duration-us" argument, thus notes triggered with this
468     argument are now correctly released after the requested amount of
469     microseconds.
470     - Fix: script events were not cleared when engine channel was reset,
471     potentially causing undefined behavior.
472     - Fixed crash which happened when trying to reference an undeclared
473     variable.
474 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
475     special value -1 for "duration-us" argument, which will cause the
476     triggered note to be released once the original note was released.
477 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
478     - Added new API method ScriptVM::syntaxHighlighting() which provides
479     a convenient syntax highlighting backend for external instrument
480     script editor applications.
481 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
482     - Extended parser issues to provide not only first line and first
483     column, but also last line and last column of issue (thus marking
484     the precise span of the issue within the source code).
485 schoenebeck 2902 - Reload script automatically after being modified by an instrument
486     editor.
487 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
488     like "on note end on".

493     - Implemented built-in script function "change_reso()".
494     - Implemented built-in script function "event_status()".
495     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
496     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
497     "event_status()" function.
498     - NKSP language: Added support for bitwise operators ".or.", ".and."
499     and ".not.".
500     - NKSP language scanner: Fixed IDs matching to require at least one
501     character (i.e. when matching function names or variable names).
502     - NKSP language scanner: disabled unusued rules.
503 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
504     be distinguished engine internally from "real" MIDI note on/off
505     events in order to avoid misbehaviors like hanging notes.
506 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
507     - Implemented built-in script variable "$NKSP_REAL_TIMER".
508     - Implemented built-in script variable "$NKSP_PERF_TIMER".

511     - Implemented built-in script function "dec()".
512     - NKSP language fix: division expressions were evaluated too often.
513     - NKSP language fix: string concatenation operator was right
514     associative instead of left (to right).
515 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
516     (i.e. "if end if").
517 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
518     - Implemented built-in script variable "$NI_CALLBACK_ID".
519     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
520     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
521     - Added support for read-only built-in variables (respectively

529     - Implemented built-in script function "change_decay()".
530     - Implemented built-in script function "change_release()".
531 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
532     synthesis parameter changes immediately in case the respective note
533     was triggered at the same time, instead of scheduling the parameter
534     change, especially because it would cause some parameter types's
535     changes either to be ramped (i.e. change_vol()) or other types even
536     to have not effect at all (i.e. change_attack()).
537 schoenebeck 2965 - Implemented built-in script function "sh_left()".
538     - Implemented built-in script function "sh_right()".
539 schoenebeck 2970 - Implemented built-in script function "min()".
540     - Implemented built-in script function "max()".
541 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
542     was loaded.
543     - NKSP built-in wait() script function: abort script execution if
544     a negative or zero wait time was passed as argument (since this is
545     a common indication of a bug either of the script or even of the
546     engine, which could lead to RT instability or even worse).
547 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
548     threatening scripts.
549 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
550 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
551     initializer list to an array variable.
552 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
553 schoenebeck 3076 - Implemented built-in script function "in_range()".

559     - Implemented built-in script function "change_tune_time()".
560     - Implemented built-in script function "fade_in()".
561     - Implemented built-in script function "fade_out()".
562     - Fixed acceptance of wrong data type of parameters passed to built-in
563     script functions "change_vol()", "change_tune()", "change_pan()",
564     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
565     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
566     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
567 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
568     of its possible parameter selections.
569     - Added built-in script function "set_event_par()" and implemented some
570     of its possible parameter selections.
571 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
572 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
573 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
574     built-in function "ignore_controller()".
575 schoenebeck 3214 - Implemented built-in script function "change_velo()".
576     - Implemented built-in script function "change_note()".
577 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
578     intuitive behavior if used in combination with "change_vol_time()" or
579     "change_tune_time()" respectively: now tuning/volume changes are only
580     assigned (without delay) immediately to a new note if the respective
581     timing function has not been called before, otherwise the volume/tuning
582     changes are automatically faded (before, only the event's time stamp was
583     relevant).
584 schoenebeck 3221 - Implemented built-in script function "array_equal()".
585     - Implemented built-in script function "search()".
586     - Implemented built-in script function "sort()".
587     - NKSP Fix: Never suspend "init" event handlers.
588 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
589     available for gig format engine).
590 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
591     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
592     - Implemented built-in script function "change_vol_curve()".
593     - Implemented built-in script function "change_tune_curve()".
594 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
595     offset with argument 3, where special value -1 means to use the regular
596     sample offset as defined by the instrument file.
597 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
598     - Built-in variable $EVENT_NOTE is now a read-only variable.
599     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
600     - built-in "play_note()" function now accepts -2 for its fourth argument
601     (note duration) which means the life time of the note shall be sticked
602     to the requested note number of argument 1.
603     - Fix: built-in "play_note()" function now returns 0 as result value if
604     -1 was passed for its fourth argument (note duration) and the respective
605     parent note is already gone.
606 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
607 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

615 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
616     "init" event handlers.
617 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
618     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
619     to retrieve all code blocks filtered out by the preprocessor.
620 schoenebeck 3293 - Added built-in script function "fork()".
621     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
622     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

628 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
629     "change_decay()" and "change_release()" to i.e. allow passing 2000000
630     for doubling the respective time.
631 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
632     to a lexer start condition stack underrun.
633     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
634     USE_CODE_IF_NOT() preprocessor statements.
635 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
636     can be set to disable all subsequent built-in "message()" function calls
637     on preprocessor level.
638 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
639 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
640     to avoid the editor app to crash on ill-formed text input.
641 schoenebeck 3335 - Added built-in script function "change_pan_time()".
642     - Added built-in script function "change_pan_curve()".

657     - Added support for scanning Sound Font (.sf2) files.
658 schoenebeck 3101 - Fixed undefined DB transaction behavior.

700 persson 2086 * general changes:
701 iliev 2012 - Refactoring: moved the independent code from
702     the Gigasampler format engine to base classes
703 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
704     respective profiling code is currently broken
705 schoenebeck 2053 - Introduced support for optional environment variable
706     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
707     where the sampler shall look for instrument editor plugins

709 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
710     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
711     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per

714     effect type is)
715     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
716     note (in this implementation of the sampler its simply hard routed to
717     the 2nd effect send of the sampler channel, no matter what the actual
718     effect type is)
719 schoenebeck 2124 - implemented support for internal LADSPA effects
720 schoenebeck 2140 - raised limit of program change queue from 100 to 512
721     (as suggested by Alex Stone)

723 iliev 2296 - experimental support for per voice equalization
724 iliev 2306 - added command line option --exec-after-init
725 schoenebeck 2330 - Introduced new C++ API method:
726     EngineChannel::InstrumentFileName(int index)
727     allowing to retrieve the whole list of files used for the loaded
728     instrument on an engine channel (a.k.a. part). Some GigaStudio
729     instruments for example are splitted over several files like
730     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
731 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
732     - Added new C++ API method Sampler::GetGlobalMaxStreams().
733     - Added new C++ API method Sampler::SetGlobalMaxVoices().
734     - Added new C++ API method Sampler::SetGlobalMaxStreams().
735 schoenebeck 2377 - Various "const" and "restrict" optimizations.
736 persson 2382 - all engines: add pan CC value to instrument pan parameter before
737     applying panning, instead of using two separate pan functions in
738     series (#182)
739 persson 2427 - added a lock guard class for exception safe mutex handling and
740     used it everywhere appropriate
741 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
742     - Exposed scale tuning to C++ API (along to the already existing standard
743     SysEx way).
744 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
745     and broken for ppc64. (Seq_cst loads and stores are actually not
746     used in LS, so the bug wasn't noticable.)
747     - lsatomic.h: added ARMv7 support
748 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
749     added various new C++ methods for this new feature / design change, old
750     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
751     as deprecated but are still there and should provide full behavior
752     backward compatibility).
753     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
754     unsafe and caused compilation error with clang 2.x).
755 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
756 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
757     sampler from the command line by providing LSCP aware features.
758 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
759     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
760     - VirtualMidiDevice: Added support for pitch bend.
761 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
762     polyphonic key pressure events (so far polyphonic pressure was not
763     supported at all, and channel pressure was rerouted as CC128 but not
764     used so far).
765 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
766     code is shared by all sampler engine implemementations, however only the
767     gig file format currently provides support for storing instrument scripts
768     (as LinuxSampler extension to the original GigaStudio 4 format).

1170     instrument was completely reloaded again.
1171 persson 2277 - fixed handling of rapid bank select and program change messages

1195 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1196     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1197     practically irrelevant, however it caused problems with the new LSCP
1198     shell's auto completion feature).
1199 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1200     after each other (fixes #231).

1252     stacktrace mechanism seems to be broken on most systems at the moment)
1253 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1254     a pointer to the launched InstrumentEditor object
1255 schoenebeck 1876 - added optional 3rd party user data parameter for following

1321     works with both standalone mode and VST plugin.
1322     the instruments DB file is located in
1323     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1324     databases for each windows user
1325     if no DB is present it automatically creates the .linuxsampler subdir
1326     and then creates an empty DB
1327 persson 1943 - fixed recursive import, which was broken on Windows
1328 iliev 1603
1329 persson 1644 * Gigasampler format engine:

1341     connected to the respective MIDI input port the SysEx message arrived
1342     on)
1343 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1344     sometimes wrongly killed in the same buffer, causing no sound to
1345     be played
1346 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1347     which is usally used to switch a part between chromatic sounds and
1348     drumkit sounds (as opposed to their common default setting of MIDI
1349     part 10 being a drumkit part and all other ones chromatic parts), in
1350     LS however one can switch between the first 16 MIDI instrument maps
1351     defined for the sampler
1352 persson 1764 - made it possible to create multiple sample channels even if the
1353     audio thread isn't running

1357     sampler engine anymore
1358     - re-cache samples in case they were changed by an instrument editor,
1359     e.g. when a sample was added while playing (#82)
1360 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1361     same time stamp as the voice's note-on event and occured both in the
1362     same audio fragment cycle (fixes bug #112)
1363 persson 1858 - added support for the "fine tune" and "pitch bend range"
1364     instrument-level gig parameters
1365     - fixed minor artifacts in pitch bend handling
1366 schoenebeck 1860 - added support for GS Reset SysEx message
1367 persson 1862 - allow gig files to use unlimited downward pitch shifting
1368     - added a limit check for upward pitch shifting
1369 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1370     note was silent
1371 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1372     same time a new instrument was loading
1373 persson 1644
1374 schoenebeck 1687 * LSCP server:
1375     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

1377     Note-On and Note-Off events are sent via this LSCP event)
1378 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1379     react on MIDI data arriving on certain MIDI input devices (so far only
1380     Note-On and Note-Off events are sent via this LSCP event)
1381 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1382     SET DB_INSTRUMENT FILE_PATH
1383 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1384     frontends to send MIDI messages to specific sampler channel
1385     - added two additional fields to GET FILE INSTRUMENT INFO command -
1386     KEY_BINDINGS and KEYSWITCH_BINDINGS
1387 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1388     was incorrect
1389 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1390 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1391     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1392     be triggered respectively
1393     - added new LSCP command "SET STREAMS" to globally alter the maximum
1394     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1395     which will be triggered respectively
1396 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1397     a gigedit file dialog is opened)
1398 iliev 1848 - close all connections when LSCPServer is deleted
1399 iliev 1882 - hard close of all sockets on exit
1400 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1401     driver
1402 schoenebeck 1687
1403 iliev 1761 * Bug fixes:
1404     - fixed a crash which occurs when removing a sampler channel waiting
1405     to start instrument loading after another channel
1406 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1407     instrument loading in progress (bug #113)
1408 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1409     instrument with PERSISTENT load mode
1410 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1411     - fixed memory leaks when issuing the following LSCP commands:
1412     GET AUDIO_OUTPUT_DRIVER INFO
1413     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1414     GET MIDI_INPUT_DRIVER INFO
1415     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1416     - fixed possible compilation error when sqlite is not present
1417 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1418 iliev 1847 - fixed crash when changing the audio output device of a sampler
1419     channel with loaded instrument and start playing notes
1420 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1421 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1422     PowerPC, which probably could cause crashes on that platform
1423 persson 1889 - fixed a memory management error which could cause a crash when a
1424     plugin was unloaded
1425 persson 1896 - bugfix: two private structs had the same name, which could cause
1426     problems if the linker chose the wrong constructor
1427 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1428     Windows
1429 iliev 1761

1431 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1432 schoenebeck 1454
1433     * packaging changes:
1434     - added autoconf checks for pthread library
1435     - added autoconf check for pthread bug found on certain NPTL-enabled
1436     glibc versions (see Gentoo bug report #194076)
1437 senoner 1502 - added autoconf checks for MS Windows
1438 schoenebeck 1454
1439 persson 1455 * general changes:
1440     - bugfix: the thread used by an editor plugin didn't die when the
1441     editor closed
1442 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1443     out all the space. operator--() did not apply size_mask after
1444     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1445     order to avoid problems with the _NonVolatileReader functions.
1446     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1447     GetWriteSpace(). Since this function is currently only used in
1448     the stream's qsort() compare function, it didn't trigger any
1449     bugs.
1450     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1451     24bit mode too. Faster method to read 24bit words on little
1452     endian machines (x86): replaced 3 byte reads + shifts with a 1
1453     unaligned 32bit read and shift
1454     - experimental support for MS Windows (MIDI input via MME, AUDIO
1455     output via ASIO)
1456     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1457 iliev 1541 - support for monitoring the total number of active disk streams
1458     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1459     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1460 persson 1455
1461 senoner 1500 * AUDIO driver:
1462 persson 1534 - added Windows ASIO low latency audio driver
1463 senoner 1500
1464 senoner 1485 * MIDI driver:
1465 schoenebeck 1495 - added MME Windows MIDI driver
1466 senoner 1485
1467 schoenebeck 1471 * LSCP server:
1468     - added support for Windows style path / filenames, however with
1469     forward slash path separators instead of backslash
1470     (i.e. "C:/foo/bar.gig")
1471 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1472     apostrophes as well
1473 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1474     "LIST FILE INSTRUMENTS <file>" and
1475     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1476     about an arbitrary instrument file on the system where the sampler is
1477     running on
1478 schoenebeck 1471
1479 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1480 schoenebeck 947
1481 schoenebeck 1065 * packaging changes:
1482 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1483     API header files anymore
1484 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1485     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1486 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1487     capable to execute our autoconf environment, thus no need anymore
1488     to maintain the compile time configuration file (osx/version.h) for
1489     OSX manually (patch by Toshi Nagata)
1490 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1491     parameters
1492 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1493     C++ API header files, all implementation internal global definitions
1494     are now in global_private.h
1495     - atomic.h is not exposed to the C++ API anymore
1496     - no need to include config.h anymore for using LS's API header files
1497     - fixed warnings in API doc generation
1498 schoenebeck 1065
1499 schoenebeck 947 * general changes:
1500     - replaced the old, confusing MIDI program change mechanism by a
1501     flexible MIDI instrument mapper which allows to map arbitrary
1502 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1503 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1504     loaded on the respective channel when such MIDI program change
1505     messages arrive, beside that, each entry allows to define a life-time
1506     strategy for the instrument, so the user can define whether the
1507     instrument should i.e. be permanently loaded (to be able to switch
1508     quickly among sounds) or i.e. loaded just on demand when the
1509     respective program change arrives (to safe RAM space), as well as a
1510     global volume factor for each entry, so the user can adjust the volume
1511     dynamic of his mapped instrument collection without having to modify
1512 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1513     MIDI instrument maps and assign each sampler channel individually
1514     a certain map, so that i.e. separation of normal instruments and
1515     drumkits is possible
1516 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1517     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1518 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1519     due to a constant size RingBuffer FIFO which is now replaced by a
1520     dynamic (unlimited) size std::list FIFO
1521 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1522     output channels for being processed by external effect processors
1523     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1524     controllers
1525 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1526 iliev 1130 - Implemented new, improved notification system
1527 schoenebeck 1149 - fixed compilation errors regarding OSX
1528     (patch by Toshi Nagata)
1529 iliev 1161 - implemented instruments database
1530 iliev 1345 - added support for escape sequences to the instruments database
1531 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1532     within the sampler's process (by using instrument editor plugins),
1533     you'll notice the new "Registered instrument editors:" message on
1534 schoenebeck 1407 startup, added a new LSCP command:
1535     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1536 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1537     given sampler channel, the plugin path can be overridden at compile
1538     time with ./configure --enable-plugin-dir=/some/dir
1539 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1540     in the sampler's process to safely edit instruments while playing
1541     without a crash (hopefully) by either suspending single regions
1542     wherever possible or if unavoidable whole engine(s)
1543 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1544     policy and priority on thread level, set a minimum stack size for
1545     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1546     threads simply inherited properties of starting thread instead of
1547     setting their own policy and priority
1548 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1549     main process did not wait for the stack trace process to finish
1550     its output
1551 persson 1248 - fixed some minor memory leaks
1552 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1553     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1554 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1555     register, to avoid relocations in the text segment at runtime)
1556 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1557 schoenebeck 947
1558     * MIDI driver:
1559     - dispatch bank select (MSB and LSB) messages
1560    
1561 schoenebeck 1049 * audio driver:
1562     - the ALSA audio output driver parameters now reflect the correct
1563     parameter value ranges for the respective selected sound card
1564     (patch by Till Wimmer, a bit fixed and extended)
1565    
1566 persson 951 * Gigasampler format engine:
1567     - if a filter is used and EG2 finishes before EG1, let the voice
1568     die when EG2 has finished (this fixes a problem with clicks and
1569     voice starvation for some gigs)
1570 persson 1038 - playback is no longer disabled during instrument loading
1571     - all notes playing on a channel that changes its instrument keep
1572     playing with the old instrument until they get a note off
1573     command
1574 persson 1039 - EG fix: a release value of zero could cause noises or crash
1575 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1576 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1577     above max sustain level, which means that there is a decay phase
1578     even if sustain is 100%
1579 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1580     noises or crashes
1581 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1582 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1583     supplied to the configure script (fixes #46)
1584 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1585     instead of a fix value
1586 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1587     127 (solo mode) only kill voices if the respective mode really
1588     changed
1589 persson 951
1590 schoenebeck 1244 * LSCP server:
1591     - fixed compile time error for old Bison versions
1592     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1593 schoenebeck 1245 - parser now supports extended ASCII character set
1594     (up to ASCII code 255, i.e. includes now umlauts and accents)
1595     - filename arguments in LSCP commands now allow to use escape
1596     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1597     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1598     code value like \xf2) (fixes bug #24)
1599 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1600     least one of their text-based parameters (i.e. name, description):
1601     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1602     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1603     "SET DB_INSTRUMENT_DIRECTORY NAME",
1604     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1605     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1606     "FIND DB_INSTRUMENT_DIRECTORIES"
1607 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1608     occured, the unexpected character and the actually expected, possible
1609     character(s), the latter only if less than 5 possibilities)
1610 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1611     settings
1612 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1613     of strings were treated as being one string containing commas
1614     (fixes #57)
1615 schoenebeck 1244
1616 iliev 959 * Bug fixes:
1617     - fixed crash occurring on certain LSCP scripts (Bug 39)
1618 persson 1038 - another thread safety fix for lscp "load engine" and "set
1619     channel audio output device"
1620 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1621     on a sampler channel with connected MIDI device
1622 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1623     device connected to a sampler channel to number less then or equal
1624     to the index of the port to which the sampler channel is connected.
1625 iliev 1296 - The previous bindings were not been disconnected when altering
1626     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1627     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1628 iliev 1297 - The active stream/voice count statistic was incorrect.
1629 iliev 1298 - notification events were not been sent for some sampler
1630     channel changes
1631 iliev 1305 - added default min and max values to restrict the number of allowed
1632     audio output channels and MIDI input ports
1633 iliev 1306 - the connection to the PCM interface is now closed when destroying
1634     an audio output device
1635 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1636 iliev 959
1637 schoenebeck 1221 * test cases:
1638     - updated and fixed (haven't been touched in a while)
1639    
1640 schoenebeck 937 Version 0.4.0 (24 November 2006)
1641 persson 696
1642 schoenebeck 697 * packaging changes:
1643 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1644     to post-(un)install steps; added devel package for liblinuxsampler;
1645     to linuxsampler.spec (RPM)
1646 schoenebeck 697 - install necessary development header files for allowing 3rd party
1647     applications to link against liblinuxsampler
1648     - liblinuxsampler's API documentation can be generated with 'make docs'
1649     (Doxygen required)
1650 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1651     implementation (currently either an integer math solution or a
1652     di-harmonic approximation), automatic detection can be overriden
1653     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1654     configure script argument though (mandatory for cross-compilation)
1655 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1656     provided some on his own (as CXXFLAGS)
1657 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1658     messages
1659 schoenebeck 852 - added compile time options to allow disabling the various audio and
1660     MIDI drivers
1661 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1662     (patch by Ebrahim Mayat)
1663 schoenebeck 697
1664 persson 696 * Gigasampler format engine:
1665 schoenebeck 738 - extensive synthesis optimization
1666     (reimplementation of EGs and LFO(s), removed synthesis parameter
1667     prerendering and the synthesis parameter matrix in general, splitting
1668     each audio fragment into subfragments now where each subfragment uses
1669 persson 830 constant pitch and filter coefficients. The volume coefficient is
1670     linearly interpolated inside a subfragment, unless
1671     --disable-interpolate-volume is set.)
1672 persson 696 - fine tuning of the EG modulation parameters
1673 persson 729 - improved filter cutoff calculation by adding support for the
1674     following gig parameters: Cutoff freq (used when no cutoff
1675     controller is defined), Control invert, Minimum cutoff, Velocity
1676 persson 791 curve and Velocity range. The keyboard tracking now scales
1677     cutoff frequency instead of resonance.
1678 persson 877 - added support for gig parameter Resonance.
1679 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1680 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1681     which can be overridden with --enable-global-attenuation
1682 persson 783 - EG fixes: made the length of "attack hold" stage more
1683     accurate. Release stage can now start before attack stage
1684 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1685     time now has a minimal value to prevent clicks.
1686 persson 799 - fixed pitch changes larger than one octave
1687 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1688     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1689     all modes can be altered via standard GM messages, that is CC5 for
1690     altering portamento time, CC65 for enabling / disabling portamento
1691     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1692 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1693     parameter) and crossfade
1694 persson 831 - added support for the "attenuation controller threshold" gig
1695     parameter
1696 persson 832 - added smoothing of volume changes caused by control change
1697     messages
1698 persson 865 - sample loop parameters are now taken from the DimensionRegion
1699     instead of the wave chunk
1700     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1701     not equal to a power of two
1702 persson 877 - reimplementation of the filter algorithm. The new filter is more
1703     accurate and supports all gig filter types, including bandreject
1704     and lowpass turbo.
1705 persson 903 - real support for 24 bit samples - samples are not truncated to
1706     16 bits anymore
1707     - support for aftertouch (channel pressure, not polyphonic
1708     aftertouch)
1709 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1710     amplifying from 0)
1711 persson 696
1712 schoenebeck 711 * LSCP server:
1713     - fixed application exit on broken pipe error (fixes bug #20)
1714 iliev 793 - fixed the notification messages delay due to lack of
1715     network activity (fixes bug #26)
1716 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1717     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1718 schoenebeck 711
1719 schoenebeck 838 * audio driver:
1720     - added aRts audio output driver (by no means RT safe)
1721    
1722 schoenebeck 775 * MIDI driver:
1723     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1724     messages several times instead of once
1725 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1726     for events (i.e. for offline rendering based MIDI drivers)
1727 persson 922 - added checks for bad MIDI data
1728 schoenebeck 775
1729 schoenebeck 900 * linuxsampler application:
1730     - show available sampler engine types on startup
1731    
1732 schoenebeck 705 * general changes:
1733     - support for muting sampler channels and solo mode of the same, two new
1734     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1735     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1736     introduced for this, the behavior is the same like on a mixer console
1737 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1738     --enable-process-muted-channels which can be used to enable the
1739     processing of muted channels.
1740 iliev 777 - support for sostenuto pedal
1741 iliev 779 - support for monitoring the total number of active voices
1742 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1743     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1744 persson 835 - fixed some memory management errors
1745 persson 841 - fixed some concurrency problems that could lead to crashes when
1746     LSCP commands were executed
1747 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1748     sampler channel (fixes bug #36)
1749 schoenebeck 705
1750 schoenebeck 692 Version 0.3.3 (15 July 2005)
1751 schoenebeck 686
1752     * packaging changes:
1753     - fixed compilation with gcc 4.0
1754    
1755 schoenebeck 687 * Gigasampler format engine:
1756     - LFO preprocessing was performed even though the respective LFO was
1757     disabled by the instrument patch (minor efficiency fix)
1758 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1759     for volume ramp downs in the same fragment (needed for current voice
1760     stealing implementation) then simply inform the user with a warning
1761     about possible click sounds and reduce the volume ramp down
1762     appropriately instead of cancelling the audio device connection
1763 schoenebeck 687
1764 schoenebeck 677 Version 0.3.2 (24 June 2005)
1765 schoenebeck 609
1766     * packaging changes:
1767     - updated autotools build files to compile on OS X
1768     (conditional compilation of CoreMIDI and MidiShare drivers)
1769 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1770     './configure --disable-asm' (definitely not recommended)
1771 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1772     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1773     (due to 'dist-bzip2' automake option)
1774 schoenebeck 649
1775     * Gigasampler format engine:
1776     - support for the gig parameters for "release velocity response" curves
1777     - fine tuning of the EGADSR envelope
1778     - volume of release triggered samples now depends on note-on velocity,
1779     note length and gig parameter "release trigger decay" instead of
1780     note-off velocity.
1781 schoenebeck 663 - revised voice stealing
1782     (fixes crash and endless loop caused by voice stealing)
1783 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1784 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1785     instead of when the respective voice is actually launched
1786     (fixes undefined behavior if stolen voices belonged to a key group -
1787     this case was followed by a "killed voice survived" error message)
1788 schoenebeck 669 - fixed minor issue with null/silence samples
1789     (those stole voices even though they don't need a voice at all which
1790     resulted in "voice stealing didn't work out" messages)
1791 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1792     instrument or audio output device change
1793 schoenebeck 654
1794 schoenebeck 620 * LSCP server:
1795 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1796 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1797 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1798 schoenebeck 609
1799 schoenebeck 668 * linuxsampler application:
1800     - added command line parameters --lscp-addr and --lscp-port to override
1801     default IP address and port of LSCP server
1802    
1803 schoenebeck 579 Version 0.3.1 (24 May 2005)
1804    
1805     * initial release
