Ref<> class: Use C++ atomics instead of C atomics (as some compilers seem
to be unable to mix C atomics with C++ code, and the generated result
should be binary identical anyway).

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

482     - Implemented built-in script function "change_reso()".
483     - Implemented built-in script function "event_status()".
484     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
485     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
486     "event_status()" function.
487     - NKSP language: Added support for bitwise operators ".or.", ".and."
488     and ".not.".
489     - NKSP language scanner: Fixed IDs matching to require at least one
490     character (i.e. when matching function names or variable names).
491     - NKSP language scanner: disabled unusued rules.
492 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
493     be distinguished engine internally from "real" MIDI note on/off
494     events in order to avoid misbehaviors like hanging notes.
495 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
496     - Implemented built-in script variable "$NKSP_REAL_TIMER".
497     - Implemented built-in script variable "$NKSP_PERF_TIMER".

499 schoenebeck 2945 - Implemented built-in script function "inc()".
500     - Implemented built-in script function "dec()".
501     - NKSP language fix: division expressions were evaluated too often.
502     - NKSP language fix: string concatenation operator was right
503     associative instead of left (to right).
504 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
505     (i.e. "if end if").
506 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
507     - Implemented built-in script variable "$NI_CALLBACK_ID".
508     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
509     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

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

548     - Implemented built-in script function "change_tune_time()".
549     - Implemented built-in script function "fade_in()".
550     - Implemented built-in script function "fade_out()".
551     - Fixed acceptance of wrong data type of parameters passed to built-in
552     script functions "change_vol()", "change_tune()", "change_pan()",
553     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
554     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
555     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
556 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
557     of its possible parameter selections.
558     - Added built-in script function "set_event_par()" and implemented some
559     of its possible parameter selections.
560 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
561 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
562 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
563     built-in function "ignore_controller()".
564 schoenebeck 3214 - Implemented built-in script function "change_velo()".
565     - Implemented built-in script function "change_note()".
566 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
567     intuitive behavior if used in combination with "change_vol_time()" or
568     "change_tune_time()" respectively: now tuning/volume changes are only
569     assigned (without delay) immediately to a new note if the respective
570     timing function has not been called before, otherwise the volume/tuning
571     changes are automatically faded (before, only the event's time stamp was
572     relevant).
573 schoenebeck 3221 - Implemented built-in script function "array_equal()".
574     - Implemented built-in script function "search()".
575     - Implemented built-in script function "sort()".

577 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
578     available for gig format engine).
579 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
580     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
581     - Implemented built-in script function "change_vol_curve()".
582     - Implemented built-in script function "change_tune_curve()".
583 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
584     offset with argument 3, where special value -1 means to use the regular
585     sample offset as defined by the instrument file.
586 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
587     - Built-in variable $EVENT_NOTE is now a read-only variable.
588     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
589     - built-in "play_note()" function now accepts -2 for its fourth argument
590     (note duration) which means the life time of the note shall be sticked
591     to the requested note number of argument 1.
592     - Fix: built-in "play_note()" function now returns 0 as result value if
593     -1 was passed for its fourth argument (note duration) and the respective
594     parent note is already gone.
595 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".

604 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
605     "init" event handlers.
606 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
607     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
608     to retrieve all code blocks filtered out by the preprocessor.
609 schoenebeck 3293 - Added built-in script function "fork()".
610     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
611     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

619     for doubling the respective time.
620 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
621     to a lexer start condition stack underrun.
622     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
623     USE_CODE_IF_NOT() preprocessor statements.
624 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
625     can be set to disable all subsequent built-in "message()" function calls
626     on preprocessor level.
627 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
628 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
629     to avoid the editor app to crash on ill-formed text input.
630 schoenebeck 3335 - Added built-in script function "change_pan_time()".
631     - Added built-in script function "change_pan_curve()".

690 iliev 2012 - Refactoring: moved the independent code from
691     the Gigasampler format engine to base classes
692 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
693     respective profiling code is currently broken
694 schoenebeck 2053 - Introduced support for optional environment variable
695     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
696     where the sampler shall look for instrument editor plugins

699     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
700     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per

703     effect type is)
704     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
705     note (in this implementation of the sampler its simply hard routed to

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

1159     instrument was completely reloaded again.
1160 persson 2277 - fixed handling of rapid bank select and program change messages

1184 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1185     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1186     practically irrelevant, however it caused problems with the new LSCP
1187     shell's auto completion feature).
1188 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1189     after each other (fixes #231).

1241     stacktrace mechanism seems to be broken on most systems at the moment)
1242 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1243     a pointer to the launched InstrumentEditor object
1244 schoenebeck 1876 - added optional 3rd party user data parameter for following

1310     works with both standalone mode and VST plugin.
1311     the instruments DB file is located in
1312     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1313     databases for each windows user
1314     if no DB is present it automatically creates the .linuxsampler subdir
1315     and then creates an empty DB
1316 persson 1943 - fixed recursive import, which was broken on Windows
1317 iliev 1603
1318 persson 1644 * Gigasampler format engine:

1330     connected to the respective MIDI input port the SysEx message arrived
1331     on)
1332 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1333     sometimes wrongly killed in the same buffer, causing no sound to
1334     be played
1335 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1336     which is usally used to switch a part between chromatic sounds and
1337     drumkit sounds (as opposed to their common default setting of MIDI
1338     part 10 being a drumkit part and all other ones chromatic parts), in
1339     LS however one can switch between the first 16 MIDI instrument maps
1340     defined for the sampler
1341 persson 1764 - made it possible to create multiple sample channels even if the
1342     audio thread isn't running

1346     sampler engine anymore
1347     - re-cache samples in case they were changed by an instrument editor,
1348     e.g. when a sample was added while playing (#82)
1349 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1350     same time stamp as the voice's note-on event and occured both in the
1351     same audio fragment cycle (fixes bug #112)
1352 persson 1858 - added support for the "fine tune" and "pitch bend range"
1353     instrument-level gig parameters
1354     - fixed minor artifacts in pitch bend handling
1355 schoenebeck 1860 - added support for GS Reset SysEx message
1356 persson 1862 - allow gig files to use unlimited downward pitch shifting
1357     - added a limit check for upward pitch shifting
1358 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1359     note was silent
1360 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1361     same time a new instrument was loading
1362 persson 1644
1363 schoenebeck 1687 * LSCP server:
1364     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1365     react on MIDI data arriving on certain sampler channels (so far only
1366     Note-On and Note-Off events are sent via this LSCP event)
1367 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1368     react on MIDI data arriving on certain MIDI input devices (so far only
1369     Note-On and Note-Off events are sent via this LSCP event)
1370 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1371     SET DB_INSTRUMENT FILE_PATH
1372 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1373     frontends to send MIDI messages to specific sampler channel
1374     - added two additional fields to GET FILE INSTRUMENT INFO command -
1375     KEY_BINDINGS and KEYSWITCH_BINDINGS
1376 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1377     was incorrect
1378 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1379 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1380     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1381     be triggered respectively
1382     - added new LSCP command "SET STREAMS" to globally alter the maximum
1383     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1384     which will be triggered respectively
1385 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1386     a gigedit file dialog is opened)
1387 iliev 1848 - close all connections when LSCPServer is deleted
1388 iliev 1882 - hard close of all sockets on exit

1394     to start instrument loading after another channel
1395 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1396     instrument loading in progress (bug #113)
1397 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1398     instrument with PERSISTENT load mode
1399 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1400     - fixed memory leaks when issuing the following LSCP commands:
1401     GET AUDIO_OUTPUT_DRIVER INFO
1402     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1403     GET MIDI_INPUT_DRIVER INFO
1404     GET MIDI_INPUT_DRIVER_PARAMETER INFO

1409 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1410 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1411     PowerPC, which probably could cause crashes on that platform
1412 persson 1889 - fixed a memory management error which could cause a crash when a
1413     plugin was unloaded
1414 persson 1896 - bugfix: two private structs had the same name, which could cause
1415     problems if the linker chose the wrong constructor

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