* Preparations for new release (2.3.1).
1 schoenebeck 4103 Version 2.3.1 (26 Mar 2024)
2 schoenebeck 4101
3     * general changes:
4     - CoreVMFunctions.cpp: Fixed compiler error with certain C++ stdlib
5     versions (due to const-ness differences with STL's std::sort()
6     implementations).
7    
8 schoenebeck 4079 Version 2.3.0 (26 Jan 2024)
9 schoenebeck 3917
10 schoenebeck 3988 * general changes:
11     - AbstractEngineChannel: fixed CCs not being forwarded to all
12     VirtualMIDIDevices.
13 schoenebeck 4002 - Fix compiler error with release tarball if no Bison installed
14     (SVN version still requires Flex and Bison being installed).
15 schoenebeck 4021 - Sampler::Reset() no longer unloads instrument editor plugins, this is a
16     workaround for the issue that instrument editor plugins were no longer
17     available after sending a LSCP "RESET" command (probably due to a race).
18 schoenebeck 3988
19 schoenebeck 3971 * Real-time instrument scripts:
20     - Fix: Do not share compiled instrument scripts among multiple engine
21     channels (sampler parts) as this can lead to crashes and would allow the
22     same global script variables to be accessible from multiple engine
23     channels which would not be the expected behaviour by instrument script
24     authors.
25    
26 schoenebeck 3917 * GigaStudio/Gigasampler format engine:
27     - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
28     issues with .gig file.
29 schoenebeck 3964 - Use libgig's new method gig::File::GetSample() with method
30     gig::File::CountSamples() instead of now deprecated
31     gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
32 schoenebeck 3966 - Use libgig's new method gig::Instrument::GetRegionAt() with method
33     gig::Instrument:CountRegions() instead of now deprecated
34     gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
35 schoenebeck 3967 - Use libgig's gig::File::GetInstrument() method with method
36     gig::File::CountInstruments() instead of now deprecated
37     gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
38 schoenebeck 4009 - Show a more detailed error message on terminal if an appropriate editor
39 schoenebeck 4010 could not be found for a .gig instrument (if there is not any editor then
40     say so, if there is one but not capable to handle the instrument, then
41     make this case clear to the user; in both cases print the expected
42     location for instrument editor plugins).
43 schoenebeck 4020 - Fixed wrong velocity for release triggered samples: if and only if
44     note-off velocity is exactly zero (which means MIDI keyboard does not have
45     release velocity sensors) then use previous note-on velocity as note-off
46     velocity for release triggered samples instead.
47 schoenebeck 3917
48 schoenebeck 4013 * SFZ format engine:
49 schoenebeck 4020 - Fixed wrong velocity for release triggered samples: if and only if
50     note-off velocity is exactly zero (which means MIDI keyboard does not have
51     release velocity sensors) then use previous note-on velocity as note-off
52     velocity for release triggered samples instead.
53 schoenebeck 4015 - sfz.h: Added File::filename() method.
54 schoenebeck 4016 - sfz.h: Added File::checkFileModified() method allowing to detect file
55     changes (e.g. by other apps).
56 schoenebeck 4018 - sfz.h: Added Instrument::GetFile() method.
57 schoenebeck 4019 - Automatically reload .sfz files on file changes (e.g. by some external
58     text editor).
59 schoenebeck 4013
60 schoenebeck 3986 * MIDI driver:
61     - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
62     in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
63 schoenebeck 3987 - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
64 schoenebeck 3986
65 schoenebeck 3880 Version 2.2.0 (9 May 2021)
66 schoenebeck 3548
67     * general changes:
68     - Fixed compiler error in Pool.h.
69 schoenebeck 3581 - Require C++14 compiler support.
70 schoenebeck 3557 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
71 schoenebeck 3581 for checking in configure for C++14 support (as mandatory
72 schoenebeck 3557 requirement) and automatically adds compiler argument if required
73 schoenebeck 3581 (e.g. -std=C++14).
74 schoenebeck 3575 - RTMath: Implemented floating point comparison methods
75     fEqual32(float,float) and fEqual64(double,double) which take the
76     expected floating point tolerances into account.
77 schoenebeck 3612 - Added public API C++ class "LFO", which is a cluster class encapsulating
78     all the sampler's LFO implementations to be used by 3rd party applications
79     (e.g. by Gigedit).
80     - Added int math square LFO implementation.
81     - Added int math saw LFO implementation.
82     - Added numeric complex nr sine LFO implementation.
83     - Marked class LFOTriangleDiHarmonic as deprecated
84     (will be removed in future).
85     - Added LFOAll.h which includes all LFO implementation's header files.
86 schoenebeck 3614 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
87     LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
88     SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
89     SquareLFO -> LFOSquarePulse and separated the latter to its own header
90     file).
91     - Renamed type LFOSigned -> LFOTriangleSigned.
92     - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
93 schoenebeck 3639 - Using now cubic interpolation as resampling algorithm by default; and
94     linear interpolation is deprecated now.
95 schoenebeck 3686 - Event:Init(): memset() entire Event::Param union to zero instead of trying
96     to do that for its individual members; the latter became error prone due
97     to the union's growing complexity meanwhile.
98 schoenebeck 3687 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
99     *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
100     methods and marked the old ones as deprecated; and likewise added new
101     *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
102     methods and marked those old ones deprecated as well.
103 schoenebeck 3688 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
104     resolution for certain (e.g. hard coded) RPN and NRPN parameters.
105 schoenebeck 3697 - Implemented support for compressed RPN/NRPN message sequences (that is to
106     allow processing MIDI data entry messages without always having to be
107     preceded strictly by RPN/NRPN parameter selection messages on each value
108     change).
109 schoenebeck 3699 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
110     decrement).
111 schoenebeck 3701 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
112     MSB=127 and LSB=127) and which is disabling subsequent data
113     entry/increment/decrement CC messages.
114 schoenebeck 3724 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
115     instrument editor.
116 schoenebeck 3725 - Fixed playing noise at the end of a disk stream under certain conditions.
117 schoenebeck 3726 - Fixed potential crash with high pitch at end of RAM playback.
118 schoenebeck 3739 - Added configure checks whether C++ compiler supports so called
119     'designated initializers'.
120 schoenebeck 3763 - Added global backtraceAsString() function for debugging purposes
121     (POSIX systems only, no Windows implementation yet).
122 schoenebeck 3764 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
123     nameOfCaller() and setNameOfCaller().
124     - configure: Always check for availability of pthread_testcancel() and use
125     it if so (previously it was only used if explicitly enabled by configure
126     option).
127     - Thread class: raise compiler warning if pthread_testcancel() is not
128     available, because it can lead to deadlocks.
129 schoenebeck 3765 - Mutex class: Implemented optional bug detection and deadlock debugging
130     features.
131 schoenebeck 3768 - Ref<> class is now thread safe (as lock-free and wait-free
132     implementation).
133 schoenebeck 3787 - Fixed compilation error with Bison >= 3.6.0.
134 schoenebeck 3802 - Fixed rare crash when switching between instruments that had instrument
135     scripts loaded.
136 schoenebeck 3840 - Allow EffectChain::InsertEffect() as alternative to
137     EffectChain::AppendEffect() (i.e. with index equal to current chain size).
138 schoenebeck 3847 - ConstCapacityArray class: Fixed bug in remove() method.
139 schoenebeck 3854 - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
140     real-time instrument script was loaded.
141 schoenebeck 3550
142 schoenebeck 3551 * Real-time instrument scripts:
143     - Added method ScriptVM::setExitResultEnabled() which allows to
144     explicitly enable the built-in exit() function to optionally accept
145     one function argument; the value of the passed exit() function
146     argument will then become available by calling
147     VMExecContext::exitResult() after script execution.
148 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
149 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
150     with a regular character (a-z or A-Z); starting them with a digit or
151     underscore is not allowed.
152     - NKSP parser fix: equal comparison operator "=" and not equal comparison
153     operator "#" must only accept integer operands.
154     - NKSP language: Implemented support for standard units like Hertz, seconds,
155     Bel including support for metric unit prefixes; so one can now e.g.
156     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
157     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
158     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
159     - NKSP language: Introduced "final" operator "!" which is specifically
160     intended for synthesis parameter values to denote that the synthesis
161     parameter value is intended to be the "final" value for that synthesis
162     parameter that should explicitly be used by the engine and thus causing
163     the sampler engine to ignore all other modulation sources for the same
164     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
165     variable or formula with this new "!" operator the expression is marked as
166     being "final".
167 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
168     and their potential metric prefix token.
169 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
170     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
171     - NKSP language: Added support for NKSP real number (floating point) script
172     variables (declare ~foo).
173     - NKSP language: Added support for NKSP real number (floating point) array
174     script variables (declare ?foo[]).
175     - Built-in script function "message()" accepts now real number argument as
176     well.
177     - Added built-in script function "real_to_int()" and its short hand form
178     "int()" for casting from real number to integer in NKSP scripts.
179     - Added built-in script function "int_to_real()" and its short hand form
180     "real()" for casting from integer to real number in NKSP scripts.
181 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
182     argument as well.
183 schoenebeck 3577 - Built-in script functions may have a different return type depending on
184     the arguments passed to the function.
185     - Built-in script function "abs()" optionally accepts and returns real
186     number.
187     - Built-in script functions "min()" and "max()" optionally accept real
188     number arguments and return real number as result in that case.
189 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
190     built-in functions (added methods VMFunction::returnUnitType() and
191     VMFunction::returnsFinal() for that purpose which must be implemented by
192     built-in function implementations).
193     - NKSP language: Allow metric unit prefixes of numeric scalar and array
194     variables to be changed freely at runtime (unlike unit types like Hz etc.
195     which are still sticky, parse-time features of variables which cannot be
196     changed at runtime for the intentional sake of determinism).
197     - NKSP language: 'final' values are prohibited for array variables for now
198     (attempt causes a parsers error).
199     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
200     conditions of runtime control structures like if(), while(), select()
201     (attempt causes a parser error).
202     - NKSP VM API: Allow built-in functions to perform their own, individual
203     parse time checks of arguments going to be passed to the function at
204     runtime (added method VMFunction::checkArgs() for that purpose).
205     - NKSP language: raise parser warning if only one operand of binary
206     operators (like logical 'or' comparison) contain a 'final' value (because
207     it would always yield in a 'final' result in such cases).
208     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
209     different metric unit prefixes, which will behave as expected (e.g.
210     result of expression '1000us < 2ms' is true).
211     - NKSP language: Allow adding values with different metric unit prefixes
212     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
213     - NKSP language: Allow subtracting values with different metric unit
214     prefixes (e.g. result of expression '1ms - 20us' is '980us').
215     - NKSP language: Allow multiplying with any metric unit prefixes
216     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
217     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
218     we don't have any considerable practical use for a term like '4s^2'
219     (hence any attempt multiplying two unit types still causes parser error).
220     - NKSP language: Allow dividing by any metric unit prefixes and allow
221     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
222     yields in unit free result '8'). So this is now a way to cast units away
223     e.g. for passing the result to other expressions, certain function calls
224     or variables which are not accepting any units (or that specific unit).
225     - NKSP language: integer arrays and real number arrays can now be converted
226     to strings (e.g. for dumping their content with message() calls for
227     script debugging purposes).
228     - NKSP language: expressions and variables with units are now correctly
229     casted to strings (e.g. with message() calls).
230     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
231     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
232     floating point tolerances into account.
233     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
234     VMScalarNumberExpr::evalCastReal().
235     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
236     'VMIntArrayExpr' and 'VMRealArrayExpr'.
237     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
238     unitFactor() (runtime) methods.
239     - Built-in function "exit()" supports now returning units and 'final'ness
240     for test cases.
241     - The following built-in functions support now units as well: "abs()",
242     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
243     "real_to_int()", "int()", "int_to_real()" and "real()".
244     - Built-in functions "array_equal()", "search()" and "sort()" support now
245     real number arrays (correctly) as well.
246     - Added individual parse time checks of arguments to be passed to built-in
247     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
248     "array_equal()" and "search()" specific for their individual purposes.
249 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
250     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
251     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
252     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
253     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
254     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
255     isScalarNumber() -> isNumber()).
256 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
257     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
258     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
259     as convenient methods for automatically converting values to expected
260     metric value basis.
261     - Built-in function "wait()" accepts now both integers and real numbers as
262     argument.
263 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
264     VMFunction::argType(vmint iArg) which was already superseded by its new
265     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
266     - NKSP parser: if wrong argument type was passed to a built-in function and
267     that built-in function accepts more than one data type for the argument,
268     then show all supported data types as parser error message.
269 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
270     unit type as well for its 3rd and 4th function arguments.
271     - The following built-in functions accept now real numbers as well for their
272     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
273     "change_attack()", "change_decay()", "change_release()",
274     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
275     "change_cutoff_sustain()", "change_cutoff_release()",
276     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
277     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
278     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
279     - Fixed built-in function "change_play_pos()" not having accepted metric
280     prefixes at all.
281 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
282     with unit type (for their 2nd argument) as if they were relative values
283     (that is as if they were passed without a unit type): "change_attack()",
284     "change_decay()", "change_release()", "change_cutoff_attack()",
285     "change_cutoff_decay()", "change_cutoff_release()".
286     - Fixed the following built-in functions having applied completely wrong
287     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
288     respective EGs being their modulation sink assume uint data type with
289     value range 0..1000 instead of 0.0..1.0.
290     - Added individual parse-time checks of function arguments for the following
291     built-in functions: "play_note()", "note_off()", "set_event_mark()",
292     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
293     "change_decay()", "change_release()", "change_cutoff_attack()",
294     "change_cutoff_decay()", "change_cutoff_release()",
295     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
296     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
297     "change_pan_time()".
298     - Don't abort function call if unit type was used and at the same time
299     'final' operator was omitted for the primary value argument of the
300     following built-in functions: "change_cutoff()", "change_attack()",
301     "change_decay()", "change_release()", "change_cutoff_attack()",
302     "change_cutoff_decay()", "change_cutoff_release()",
303     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
304     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
305     "change_pan_time()", instead imply 'final'ness at runtime and raise an
306     appropriate parser warning at parse time.
307 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
308     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
309     "cos()", "tan()", "asin()", "acos()", "atan()".
310     - Added built-in script real number constant "~NI_MATH_PI".
311     - Added built-in script real number constant "~NI_MATH_E".
312 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
313 schoenebeck 3678 - Added built-in script functions "msb()" and "lsb()".
314 schoenebeck 3690 - NKSP language: Added support for RPN event handler
315     ("on rpn ... end on" in instrument scripts).
316     - NKSP language: Added support for NRPN event handler
317     ("on nrpn ... end on" in instrument scripts).
318     - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
319     may be read from the new RPN/NRPN script handlers to get the (N)RPN
320     parameter that had been changed and its new value.
321     - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
322     which are identifying the new (N)RPN handlers as such at script runtime.
323 schoenebeck 3691 - Implemented built-in script function "set_rpn()".
324     - Implemented built-in script function "set_nrpn()".
325 schoenebeck 3714 - Fix: built-in functions returning an array type were broken and caused a
326     crash when the built-in function's (supposed to be array) result value was
327     used by the script VM.
328 schoenebeck 3715 - Removed upper value constraint for 2nd argument of built-in functions
329     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
330     "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
331     "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
332     "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
333     the LFO frequency / resonance / cutoff frequency.
334 schoenebeck 3728 - Reduced code involved for parsing NKSP variable declarations by using 2
335     generalized grammar rules with optional components (i.e. optional value
336     assignment and optional variable qualifiers) instead of previous linear
337     combinations of grammar rules, which also fixes some edge case.
338 schoenebeck 3729 - NKSP language parser: track code block locations also by a) raw byte
339     position in NKSP source code string and b) length of that code block in
340     bytes (along to the already existing code block tracking by line/column);
341     and added appropriate new members to public C++ API classes like
342     'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
343 schoenebeck 3733 - NKSP language: Added support for 'patch' variable qualifier (capture their
344     locations and allow replacement of their assignment expression via VM C++
345     API).
346 schoenebeck 3742 - Fixed incorrect EG times if standard measuring unit was passed to built-in
347     functions "change_attack()", "change_decay()" or "change_release()".
348 schoenebeck 3744 - Fixed intermediate function result values never having reflected any
349     standard measuring unit type.
350 schoenebeck 3747 - Fixed re-entrant issue with function calls which caused wrong result
351     values if the same function was called multiple times in a term
352     (specifically if metric prefixes were used).
353 schoenebeck 3790 - NKSP language: Just throw a warning, not an error if an array variable of
354     size zero was declared.
355     - NKSP language: Allow omitting explicit array size on array variable
356     declaration if combined with immediate value assignment
357     (e.g. declare %foo[] := ( 1, 2, 3 ) ).
358 schoenebeck 3792 - NKSP language: emit warning if an array variable was declared with bigger
359     array size than amount of initial values been assigned, and initialize the
360     missing array elements with zero in this case.
361 schoenebeck 3804 - Fixed built-in NKSP exit() function to behave as return statement.
362 schoenebeck 3816 - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
363     data type.
364 schoenebeck 3818 - NKSP VM: Fixed the "release" handler being executed too often under
365     certain situations if polyphonic data was passed from "note" handler to
366     "release" handler.
367 schoenebeck 3836 - Fixed memory leak in NKSP parser: string tokens were allocated as C
368     strings and never freed.
369 schoenebeck 3845 - Fixed incorrect polyphonic data transfer from wrong note handler to
370     release handler; which also fixes no release handler being executed
371     sometimes, and due to the latter it also fixes potential crashes as some
372     polyphonic script events were never released and the engine hence was
373     running out of free script events.
374 schoenebeck 3846 - Fixed crash when handling array results of built-in functions
375     (e.g. "num_elements(by_marks($MARK_1)").
376 schoenebeck 3848 - NKSP VM: Fixed dead note events not been removed from user's event groups
377     (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
378     and set_event_mark() after max. size of event group list was exhausted).
379 schoenebeck 3551
380 schoenebeck 3550 * test cases:
381 schoenebeck 3548 - Fixed compiler errors in test cases.
382     - Updated README for how to compile & run test cases.
383     - Updated test case
384     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
385     expected behaviour of the Mutex class implementation (recursive

390 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
391     int_to_real(), real(), real_to_int() and int(), as well as for the
392     plus, minus and negate language operators.
393 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
394     'final' operator usage cases.
395     - Added NKSP test cases for (floating point tolerance aware) real number
396     equalness / unequalness comparison.
397 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
398     initialization of arrays.
399 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
400     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",

405 schoenebeck 3548
406 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
407     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
408     behaviour for start_level_mid.
409 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
410     level (see discussion "GigaStudio LFO compatibility" on mailing list
411     from 2019-09-26 for details).
412 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
413     see discussion "GigaStudio LFO compatibility" on mailing list from
414     2019-09-26 for details).
415 schoenebeck 3625 - Format extension: Added support for different LFO wave forms (currently
416     either sine [default], triangle, saw or square).
417     - Format extension: Added support for LFO phase displacement (0��..360��).
418     - Format extension: Added support for flipping LFO polarity on LFO 3
419     (in the original gig format this was only available for LFO 1 and LFO 2).
420 schoenebeck 3646 - Format extension: Support for additional filter types:
421     lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
422     bandreject 2-pole.
423 schoenebeck 3719 - Fixd potential crash with polynomial interpolator and max. pitch.
424 schoenebeck 3721 - If minimum cutoff is defined, remap cutoff controller CC values to really
425     span the entire possible cutoff range (and avoiding a dead controller
426     zone).
427 schoenebeck 3733 - Implemented support for loading instrument scripts with 'patch' variables
428     (by patching these script variables with potentially overridden ones by
429     gig Instrument).
430 schoenebeck 3611
431 persson 3593 * SFZ format engine:
432     - Fixed support for regions with loccN/hiccN conditions on more than one
433     MIDI controller.
434 schoenebeck 3819 - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
435     'xfin_lovel' (patch by Christian Czezatke).
436 persson 3593
437 schoenebeck 3612 * Benchmarks:
438     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
439     algorithm (since result of 2nd run was not accumulated).
440     - Added benchmark for saw wave (benchmarks/saw.cpp).
441     - Added benchmark for sine wave (benchmarks/sine.cpp).
442     - Added benchmark for square wave (benchmarks/square.cpp).
443     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
444     which are large enough on modern systems.
445    
446 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
447 schoenebeck 3381
448     * Real-time instrument scripts:
449     - Fixed behavior of built-in NKSP functions change_sustain(),
450     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
451     and change_cutoff_release().
452    
453 schoenebeck 3444 * general changes:
454     - Only play release trigger samples on sustain pedal up if this behaviour
455     was explicitly requested by the instrument (otherwise only on note-off).
456 persson 3455 - Fixed compiler warnings.
457     - Fixed compilation error when cross-compiling to Mac.
458 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
459     (see bug #169).
460     - LSCP doc: Be more clear describing the two distinct approaches
461     of using external vs. internal effects (see bug #169).
462 schoenebeck 3514 - "optional" class: Fixed comparison operators.
463 schoenebeck 3444
464 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
465     - Format extension: If requested by instrument then don't play release
466     trigger sample on note-off events.
467    
468 schoenebeck 3487 * SFZ format engine:
469     - Fixed memory leak when releasing samples
470     (fixes bug #307, patch by Jacek Roszkowski)
471 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
472     (fixes bug #308, patch by Jacek Roszkowski).
473 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
474     (fixes bug #310, patch by Jacek Roszkowski).
475 schoenebeck 3487
476 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
477 persson 2837
478 persson 2856 * SFZ format engine:
479     - added support for <global>, <master> and #define (patch by Alby M)
480 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
481     - Added support for sfz extension opcode 'script' which may be used to
482     load real-time instrument script file (NKSP script language).
483 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
484 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
485 persson 3291 - sfz parser: allow missing space between header and opcode
486 persson 2856
487 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
488 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
489     cutoff settings.
490 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
491     all if an up-pitch of more than 40 semi tones was requested (I don't
492     think there is any stock gig sound that requires this behavior to
493     resemble its original sound).
494 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
495     be aborted (as LinuxSampler extension to the original GigaStudio 4
496     format).
497 schoenebeck 3072
498 persson 2837 * general changes:
499     - fixed printf type errors (mostly in debug messages)
500 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
501 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
502     allowing to sort data efficiently in real-time safe manner.
503     - RTList class: added methods for moving/inserting elements to arbitrary
504     position within a list.
505     - RTList class: added method fromPtr() for creating an Iterator object from
506     a raw element pointer.
507     - Attempt to partly fix resetting engine channels vs. resetting engine, an
508     overall cleanup of the Reset*(), ConnectAudioDevice(),
509     DisconnectAudioDevice() API methods would still be desirable though,
510     because the current situation is still inconsistent and error prone.
511 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
512     being directly assigned to a keyboard key. This allows more fine graded
513     processing of voices, which is i.e. required for certain instrument
514     script features.
515 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
516     (CC #64) events.
517     - Fix: Release trigger voices can now also distinguish correctly between
518     note-off and sustain pedal up events.
519 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
520     (while slow rate of crossfade smoother is preserved) to allow quick
521     volume and pan changes by instrument scripts for instance.
522 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
523     properly and thus were ignored for certain uses.
524 schoenebeck 3018 - Added new C++ API method
525     VirtualMidiDevice::SendChannelPressureToSampler().
526 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
527     sub threads is 16-byte aligned
528 schoenebeck 3054 - fixed numerous compiler warnings
529 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
530 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
531     fixes potential undefined behavior.
532 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
533     have a valid sample mapped (fixes bug #252).
534     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
535 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
536     subsequent optional argument due to glibc's implementation oddity
537     which expects a "=" sign, but no space between them.
538 persson 2837
539 schoenebeck 2866 * packaging changes:
540     - removed unnecessary dependency to libuuid
541     (originated by libgig's usage of it)
542 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
543     auto detect whether it (sh/c)ould output its messages in color.
544 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
545     substitution variable.
546     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
547 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
548     linuxsampler with instruments DB support.
549 schoenebeck 2866
550 schoenebeck 2871 * Real-time instrument scripts:
551     - Implemented scheduler for delayed MIDI events and for suspended scripts.
552     - Built-in script function "wait()": implemented support for function's
553     "duration-us" argument, thus scripts using this function are now
554     correctly resumed after the requested amount of microseconds.
555     - Built-in script function "play_note()": implemented support for
556     function's "duration-us" argument, thus notes triggered with this
557     argument are now correctly released after the requested amount of
558     microseconds.
559     - Fix: script events were not cleared when engine channel was reset,
560     potentially causing undefined behavior.
561     - Fixed crash which happened when trying to reference an undeclared
562     variable.
563 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
564     special value -1 for "duration-us" argument, which will cause the
565     triggered note to be released once the original note was released.
566 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
567     - Added new API method ScriptVM::syntaxHighlighting() which provides
568     a convenient syntax highlighting backend for external instrument
569     script editor applications.
570 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
571     - Extended parser issues to provide not only first line and first
572     column, but also last line and last column of issue (thus marking
573     the precise span of the issue within the source code).
574 schoenebeck 2902 - Reload script automatically after being modified by an instrument
575     editor.
576 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
577     like "on note end on".
578 schoenebeck 2931 - Implemented built-in script function "change_vol()".
579     - Implemented built-in script function "change_tune()".
580     - Implemented built-in script function "change_pan()".
581 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
582     - Implemented built-in script function "change_reso()".
583     - Implemented built-in script function "event_status()".
584     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
585     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
586     "event_status()" function.
587     - NKSP language: Added support for bitwise operators ".or.", ".and."
588     and ".not.".
589     - NKSP language scanner: Fixed IDs matching to require at least one
590     character (i.e. when matching function names or variable names).
591     - NKSP language scanner: disabled unusued rules.
592 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
593     be distinguished engine internally from "real" MIDI note on/off
594     events in order to avoid misbehaviors like hanging notes.
595 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
596     - Implemented built-in script variable "$NKSP_REAL_TIMER".
597     - Implemented built-in script variable "$NKSP_PERF_TIMER".
598     - Implemented built-in script variable "$ENGINE_UPTIME".
599 schoenebeck 2945 - Implemented built-in script function "inc()".
600     - Implemented built-in script function "dec()".
601     - NKSP language fix: division expressions were evaluated too often.
602     - NKSP language fix: string concatenation operator was right
603     associative instead of left (to right).
604 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
605     (i.e. "if end if").
606 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
607     - Implemented built-in script variable "$NI_CALLBACK_ID".
608     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
609     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
610     - Added support for read-only built-in variables (respectively
611     handled by the script parser).
612     - Added built-in script constant "$NI_CB_TYPE_INIT".
613     - Added built-in script constant "$NI_CB_TYPE_NOTE".
614     - Added built-in script constant "$NI_CB_TYPE_RELEASE".

617 schoenebeck 2953 - Implemented built-in script function "change_attack()".
618     - Implemented built-in script function "change_decay()".
619     - Implemented built-in script function "change_release()".
620 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
621     synthesis parameter changes immediately in case the respective note
622     was triggered at the same time, instead of scheduling the parameter
623     change, especially because it would cause some parameter types's
624     changes either to be ramped (i.e. change_vol()) or other types even
625     to have not effect at all (i.e. change_attack()).
626 schoenebeck 2965 - Implemented built-in script function "sh_left()".
627     - Implemented built-in script function "sh_right()".
628 schoenebeck 2970 - Implemented built-in script function "min()".
629     - Implemented built-in script function "max()".
630 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
631     was loaded.
632     - NKSP built-in wait() script function: abort script execution if
633     a negative or zero wait time was passed as argument (since this is
634     a common indication of a bug either of the script or even of the
635     engine, which could lead to RT instability or even worse).
636 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
637     threatening scripts.
638 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
639 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
640     initializer list to an array variable.
641 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
642 schoenebeck 3076 - Implemented built-in script function "in_range()".
643 schoenebeck 3118 - Implemented built-in script function "change_amp_lfo_depth()".

646     - Implemented built-in script function "change_pitch_lfo_freq()".
647 schoenebeck 3188 - Implemented built-in script function "change_vol_time()".
648     - Implemented built-in script function "change_tune_time()".
649     - Implemented built-in script function "fade_in()".
650     - Implemented built-in script function "fade_out()".
651     - Fixed acceptance of wrong data type of parameters passed to built-in
652     script functions "change_vol()", "change_tune()", "change_pan()",
653     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
654     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
655     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
656 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
657     of its possible parameter selections.
658     - Added built-in script function "set_event_par()" and implemented some
659     of its possible parameter selections.
660 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
661 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
662 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
663     built-in function "ignore_controller()".
664 schoenebeck 3214 - Implemented built-in script function "change_velo()".
665     - Implemented built-in script function "change_note()".
666 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
667     intuitive behavior if used in combination with "change_vol_time()" or
668     "change_tune_time()" respectively: now tuning/volume changes are only
669     assigned (without delay) immediately to a new note if the respective
670     timing function has not been called before, otherwise the volume/tuning
671     changes are automatically faded (before, only the event's time stamp was
672     relevant).
673 schoenebeck 3221 - Implemented built-in script function "array_equal()".
674     - Implemented built-in script function "search()".
675     - Implemented built-in script function "sort()".
676     - NKSP Fix: Never suspend "init" event handlers.
677 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
678     available for gig format engine).
679 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
680     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
681     - Implemented built-in script function "change_vol_curve()".
682     - Implemented built-in script function "change_tune_curve()".
683 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
684     offset with argument 3, where special value -1 means to use the regular
685     sample offset as defined by the instrument file.
686 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
687     - Built-in variable $EVENT_NOTE is now a read-only variable.
688     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
689     - built-in "play_note()" function now accepts -2 for its fourth argument
690     (note duration) which means the life time of the note shall be sticked
691     to the requested note number of argument 1.
692     - Fix: built-in "play_note()" function now returns 0 as result value if
693     -1 was passed for its fourth argument (note duration) and the respective
694     parent note is already gone.
695 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
696 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

703     another script handler by passing its callback ID.
704 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
705     "init" event handlers.
706 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
707     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
708     to retrieve all code blocks filtered out by the preprocessor.
709 schoenebeck 3293 - Added built-in script function "fork()".
710     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
711     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
712     - Fixed potential crash when accessing dynamic built-in array variables.

788 persson 2382
789 persson 2086 * general changes:
790 iliev 2012 - Refactoring: moved the independent code from
791     the Gigasampler format engine to base classes
792 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
793     respective profiling code is currently broken
794 schoenebeck 2053 - Introduced support for optional environment variable
795     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
796     where the sampler shall look for instrument editor plugins
797     (patch by Luis Garrido, slightly modified).
798 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
799     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
800     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
801     note (in this implementation of the sampler its simply hard routed to
802     the 1st effect send of the sampler channel, no matter what the actual
803     effect type is)
804     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
805     note (in this implementation of the sampler its simply hard routed to
806     the 2nd effect send of the sampler channel, no matter what the actual
807     effect type is)
808 schoenebeck 2124 - implemented support for internal LADSPA effects
809 schoenebeck 2140 - raised limit of program change queue from 100 to 512
810     (as suggested by Alex Stone)
811 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
812 iliev 2296 - experimental support for per voice equalization
813 iliev 2306 - added command line option --exec-after-init
814 schoenebeck 2330 - Introduced new C++ API method:
815     EngineChannel::InstrumentFileName(int index)
816     allowing to retrieve the whole list of files used for the loaded
817     instrument on an engine channel (a.k.a. part). Some GigaStudio
818     instruments for example are splitted over several files like
819     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
820 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
821     - Added new C++ API method Sampler::GetGlobalMaxStreams().
822     - Added new C++ API method Sampler::SetGlobalMaxVoices().
823     - Added new C++ API method Sampler::SetGlobalMaxStreams().
824 schoenebeck 2377 - Various "const" and "restrict" optimizations.
825 persson 2382 - all engines: add pan CC value to instrument pan parameter before
826     applying panning, instead of using two separate pan functions in
827     series (#182)
828 persson 2427 - added a lock guard class for exception safe mutex handling and
829     used it everywhere appropriate
830 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
831     - Exposed scale tuning to C++ API (along to the already existing standard
832     SysEx way).
833 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
834     and broken for ppc64. (Seq_cst loads and stores are actually not
835     used in LS, so the bug wasn't noticable.)
836     - lsatomic.h: added ARMv7 support
837 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
838     added various new C++ methods for this new feature / design change, old
839     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
840     as deprecated but are still there and should provide full behavior
841     backward compatibility).
842     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
843     unsafe and caused compilation error with clang 2.x).
844 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
845 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
846     sampler from the command line by providing LSCP aware features.
847 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
848     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
849     - VirtualMidiDevice: Added support for pitch bend.
850 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
851     polyphonic key pressure events (so far polyphonic pressure was not
852     supported at all, and channel pressure was rerouted as CC128 but not
853     used so far).
854 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
855     code is shared by all sampler engine implemementations, however only the
856     gig file format currently provides support for storing instrument scripts
857     (as LinuxSampler extension to the original GigaStudio 4 format).
858 iliev 2012
859 persson 2043 * Gigasampler format engine:
860     - implemented the "round robin keyboard" dimension
861     - fixed round robin and random dimensions for cases when number of

868     filter parameters in each sub fragment)
869     - handle special case when pan parameter in gig file has max or
870     min value
871 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
872     doesn't sound naturally with a drumkit

1259     instrument was completely reloaded again.
1260 persson 2277 - fixed handling of rapid bank select and program change messages

1284 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1285     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1286     practically irrelevant, however it caused problems with the new LSCP
1287     shell's auto completion feature).
1288 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1289     after each other (fixes #231).

1387 schoenebeck 1599
1388 persson 1651 * MIDI driver:
1389     - added JACK MIDI driver
1390 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
1391     want to (mis)use it for some purpose ("fixed" in all current MIDI
1392     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1393 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1394 persson 1887 CoreMidi or AU
1395 persson 1889 - fixed mingw-w64 compilation error in MME driver
1396 persson 1924 - made program change handling in MIDI thread real-time safe by
1397     moving the logic to a non-RT thread
1398 persson 1951 - fixed minor memory leak in ALSA driver
1399 persson 1651
1400 schoenebeck 1604 * instruments database:
1401 iliev 1603 - avoid time consuming samples scanning when adding instruments
1402     to the instruments database
1403 iliev 1727 - added support for handling lost files in the instruments database
1404 iliev 1781 - Implemented option for adding instruments in separate directories
1405     in the instruments database
1406     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1407 persson 1908 - work-around for missing fnmatch function on Windows to make
1408     instrument database compilable
1409 schoenebeck 1930 - added instrument database support on Windows
1410     works with both standalone mode and VST plugin.
1411     the instruments DB file is located in
1412     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1413     databases for each windows user
1414     if no DB is present it automatically creates the .linuxsampler subdir
1415     and then creates an empty DB
1416 persson 1943 - fixed recursive import, which was broken on Windows
1417 iliev 1603
1418 persson 1644 * Gigasampler format engine:
1419     - fixed a memory leak that could happen when a channel was deleted
1420     while notes were playing
1421 persson 1646 - made it possible to load an instrument even if the audio thread
1422     isn't running
1423 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1424     enough for piano gigs with pedal noise samples
1425 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1426     respective FX send MIDI controller was used
1427 schoenebeck 1724 - added support for GM global device volume SysEx message
1428 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1429     whole sampler [default] or only to the sampler channels that are
1430     connected to the respective MIDI input port the SysEx message arrived
1431     on)
1432 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1433     sometimes wrongly killed in the same buffer, causing no sound to
1434     be played
1435 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1436     which is usally used to switch a part between chromatic sounds and
1437     drumkit sounds (as opposed to their common default setting of MIDI
1438     part 10 being a drumkit part and all other ones chromatic parts), in
1439     LS however one can switch between the first 16 MIDI instrument maps
1440     defined for the sampler
1441 persson 1764 - made it possible to create multiple sample channels even if the
1442     audio thread isn't running
1443 persson 1844 - fixed crash when removing channel with active voices (#116)
1444 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1445     un-cache the respective sample if it's really not used by any
1446     sampler engine anymore
1447     - re-cache samples in case they were changed by an instrument editor,
1448     e.g. when a sample was added while playing (#82)
1449 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1450     same time stamp as the voice's note-on event and occured both in the
1451     same audio fragment cycle (fixes bug #112)
1452 persson 1858 - added support for the "fine tune" and "pitch bend range"
1453     instrument-level gig parameters
1454     - fixed minor artifacts in pitch bend handling
1455 schoenebeck 1860 - added support for GS Reset SysEx message
1456 persson 1862 - allow gig files to use unlimited downward pitch shifting
1457     - added a limit check for upward pitch shifting
1458 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1459     note was silent
1460 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1461     same time a new instrument was loading
1462 persson 1644
1463 schoenebeck 1687 * LSCP server:
1464     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1465     react on MIDI data arriving on certain sampler channels (so far only
1466     Note-On and Note-Off events are sent via this LSCP event)
1467 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1468     react on MIDI data arriving on certain MIDI input devices (so far only
1469     Note-On and Note-Off events are sent via this LSCP event)
1470 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1471     SET DB_INSTRUMENT FILE_PATH
1472 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1473     frontends to send MIDI messages to specific sampler channel
1474     - added two additional fields to GET FILE INSTRUMENT INFO command -
1475     KEY_BINDINGS and KEYSWITCH_BINDINGS
1476 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1477     was incorrect
1478 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1479 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1480     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1481     be triggered respectively
1482     - added new LSCP command "SET STREAMS" to globally alter the maximum
1483     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1484     which will be triggered respectively
1485 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1486     a gigedit file dialog is opened)
1487 iliev 1848 - close all connections when LSCPServer is deleted
1488 iliev 1882 - hard close of all sockets on exit
1489 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1490     driver
1491 schoenebeck 1687
1492 iliev 1761 * Bug fixes:
1493     - fixed a crash which occurs when removing a sampler channel waiting
1494     to start instrument loading after another channel
1495 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1496     instrument loading in progress (bug #113)
1497 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1498     instrument with PERSISTENT load mode
1499 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1500     - fixed memory leaks when issuing the following LSCP commands:
1501     GET AUDIO_OUTPUT_DRIVER INFO
1502     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1503     GET MIDI_INPUT_DRIVER INFO
1504     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1505     - fixed possible compilation error when sqlite is not present
1506 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1507 iliev 1847 - fixed crash when changing the audio output device of a sampler
1508     channel with loaded instrument and start playing notes
1509 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1510 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1511     PowerPC, which probably could cause crashes on that platform
1512 persson 1889 - fixed a memory management error which could cause a crash when a
1513     plugin was unloaded
1514 persson 1896 - bugfix: two private structs had the same name, which could cause
1515     problems if the linker chose the wrong constructor
1516 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1517     Windows
1518 iliev 1761

1520 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1521 schoenebeck 1454
1522     * packaging changes:
1523     - added autoconf checks for pthread library
1524     - added autoconf check for pthread bug found on certain NPTL-enabled
1525     glibc versions (see Gentoo bug report #194076)
1526 senoner 1502 - added autoconf checks for MS Windows
1527 schoenebeck 1454
1528 persson 1455 * general changes:
1529     - bugfix: the thread used by an editor plugin didn't die when the
1530     editor closed
1531 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1532     out all the space. operator--() did not apply size_mask after
1533     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1534     order to avoid problems with the _NonVolatileReader functions.
1535     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1536     GetWriteSpace(). Since this function is currently only used in
1537     the stream's qsort() compare function, it didn't trigger any
1538     bugs.
1539     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1540     24bit mode too. Faster method to read 24bit words on little
1541     endian machines (x86): replaced 3 byte reads + shifts with a 1
1542     unaligned 32bit read and shift
1543     - experimental support for MS Windows (MIDI input via MME, AUDIO
1544     output via ASIO)
1545     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1546 iliev 1541 - support for monitoring the total number of active disk streams
1547     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1548     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1549 persson 1455
1550 senoner 1500 * AUDIO driver:
1551 persson 1534 - added Windows ASIO low latency audio driver
1552 senoner 1500
1553 senoner 1485 * MIDI driver:
1554 schoenebeck 1495 - added MME Windows MIDI driver
1555 senoner 1485
1556 schoenebeck 1471 * LSCP server:
1557     - added support for Windows style path / filenames, however with
1558     forward slash path separators instead of backslash
1559     (i.e. "C:/foo/bar.gig")
1560 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1561     apostrophes as well
1562 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1563     "LIST FILE INSTRUMENTS <file>" and
1564     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1565     about an arbitrary instrument file on the system where the sampler is
1566     running on
1567 schoenebeck 1471
1568 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1569 schoenebeck 947
1570 schoenebeck 1065 * packaging changes:
1571 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1572     API header files anymore
1573 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1574     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1575 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1576     capable to execute our autoconf environment, thus no need anymore
1577     to maintain the compile time configuration file (osx/version.h) for
1578     OSX manually (patch by Toshi Nagata)
1579 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1580     parameters
1581 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1582     C++ API header files, all implementation internal global definitions
1583     are now in global_private.h
1584     - atomic.h is not exposed to the C++ API anymore
1585     - no need to include config.h anymore for using LS's API header files
1586     - fixed warnings in API doc generation
1587 schoenebeck 1065
1588 schoenebeck 947 * general changes:
1589     - replaced the old, confusing MIDI program change mechanism by a
1590     flexible MIDI instrument mapper which allows to map arbitrary
1591 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1592 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1593     loaded on the respective channel when such MIDI program change
1594     messages arrive, beside that, each entry allows to define a life-time
1595     strategy for the instrument, so the user can define whether the
1596     instrument should i.e. be permanently loaded (to be able to switch
1597     quickly among sounds) or i.e. loaded just on demand when the
1598     respective program change arrives (to safe RAM space), as well as a
1599     global volume factor for each entry, so the user can adjust the volume
1600     dynamic of his mapped instrument collection without having to modify
1601 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1602     MIDI instrument maps and assign each sampler channel individually
1603     a certain map, so that i.e. separation of normal instruments and
1604     drumkits is possible
1605 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1606     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1607 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1608     due to a constant size RingBuffer FIFO which is now replaced by a
1609     dynamic (unlimited) size std::list FIFO
1610 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1611     output channels for being processed by external effect processors
1612     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1613     controllers
1614 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1615 iliev 1130 - Implemented new, improved notification system
1616 schoenebeck 1149 - fixed compilation errors regarding OSX
1617     (patch by Toshi Nagata)
1618 iliev 1161 - implemented instruments database
1619 iliev 1345 - added support for escape sequences to the instruments database
1620 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1621     within the sampler's process (by using instrument editor plugins),
1622     you'll notice the new "Registered instrument editors:" message on
1623 schoenebeck 1407 startup, added a new LSCP command:
1624     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1625 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1626     given sampler channel, the plugin path can be overridden at compile
1627     time with ./configure --enable-plugin-dir=/some/dir
1628 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1629     in the sampler's process to safely edit instruments while playing
1630     without a crash (hopefully) by either suspending single regions
1631     wherever possible or if unavoidable whole engine(s)
1632 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1633     policy and priority on thread level, set a minimum stack size for
1634     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1635     threads simply inherited properties of starting thread instead of
1636     setting their own policy and priority
1637 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1638     main process did not wait for the stack trace process to finish
1639     its output
1640 persson 1248 - fixed some minor memory leaks
1641 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1642     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1643 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1644     register, to avoid relocations in the text segment at runtime)
1645 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1646 schoenebeck 947
1647     * MIDI driver:
1648     - dispatch bank select (MSB and LSB) messages
1649    
1650 schoenebeck 1049 * audio driver:
1651     - the ALSA audio output driver parameters now reflect the correct
1652     parameter value ranges for the respective selected sound card
1653     (patch by Till Wimmer, a bit fixed and extended)
1654    
1655 persson 951 * Gigasampler format engine:
1656     - if a filter is used and EG2 finishes before EG1, let the voice
1657     die when EG2 has finished (this fixes a problem with clicks and
1658     voice starvation for some gigs)
1659 persson 1038 - playback is no longer disabled during instrument loading
1660     - all notes playing on a channel that changes its instrument keep
1661     playing with the old instrument until they get a note off
1662     command
1663 persson 1039 - EG fix: a release value of zero could cause noises or crash
1664 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1665 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1666     above max sustain level, which means that there is a decay phase
1667     even if sustain is 100%
1668 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1669     noises or crashes
1670 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1671 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1672     supplied to the configure script (fixes #46)
1673 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1674     instead of a fix value
1675 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1676     127 (solo mode) only kill voices if the respective mode really
1677     changed
1678 persson 951
1679 schoenebeck 1244 * LSCP server:
1680     - fixed compile time error for old Bison versions
1681     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1682 schoenebeck 1245 - parser now supports extended ASCII character set
1683     (up to ASCII code 255, i.e. includes now umlauts and accents)
1684     - filename arguments in LSCP commands now allow to use escape
1685     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1686     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1687     code value like \xf2) (fixes bug #24)
1688 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1689     least one of their text-based parameters (i.e. name, description):
1690     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1691     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1692     "SET DB_INSTRUMENT_DIRECTORY NAME",
1693     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1694     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1695     "FIND DB_INSTRUMENT_DIRECTORIES"
1696 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1697     occured, the unexpected character and the actually expected, possible
1698     character(s), the latter only if less than 5 possibilities)
1699 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1700     settings
1701 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1702     of strings were treated as being one string containing commas
1703     (fixes #57)
1704 schoenebeck 1244
1705 iliev 959 * Bug fixes:
1706     - fixed crash occurring on certain LSCP scripts (Bug 39)
1707 persson 1038 - another thread safety fix for lscp "load engine" and "set
1708     channel audio output device"
1709 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1710     on a sampler channel with connected MIDI device
1711 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1712     device connected to a sampler channel to number less then or equal
1713     to the index of the port to which the sampler channel is connected.
1714 iliev 1296 - The previous bindings were not been disconnected when altering
1715     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1716     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1717 iliev 1297 - The active stream/voice count statistic was incorrect.
1718 iliev 1298 - notification events were not been sent for some sampler
1719     channel changes
1720 iliev 1305 - added default min and max values to restrict the number of allowed
1721     audio output channels and MIDI input ports
1722 iliev 1306 - the connection to the PCM interface is now closed when destroying
1723     an audio output device
1724 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1725 iliev 959
1726 schoenebeck 1221 * test cases:
1727     - updated and fixed (haven't been touched in a while)
1728    
1729 schoenebeck 937 Version 0.4.0 (24 November 2006)
1730 persson 696
1731 schoenebeck 697 * packaging changes:
1732 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1733     to post-(un)install steps; added devel package for liblinuxsampler;
1734     to linuxsampler.spec (RPM)
1735 schoenebeck 697 - install necessary development header files for allowing 3rd party
1736     applications to link against liblinuxsampler
1737     - liblinuxsampler's API documentation can be generated with 'make docs'
1738     (Doxygen required)
1739 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1740     implementation (currently either an integer math solution or a
1741     di-harmonic approximation), automatic detection can be overriden
1742     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1743     configure script argument though (mandatory for cross-compilation)
1744 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1745     provided some on his own (as CXXFLAGS)
1746 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1747     messages
1748 schoenebeck 852 - added compile time options to allow disabling the various audio and
1749     MIDI drivers
1750 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1751     (patch by Ebrahim Mayat)
1752 schoenebeck 697
1753 persson 696 * Gigasampler format engine:
1754 schoenebeck 738 - extensive synthesis optimization
1755     (reimplementation of EGs and LFO(s), removed synthesis parameter
1756     prerendering and the synthesis parameter matrix in general, splitting
1757     each audio fragment into subfragments now where each subfragment uses
1758 persson 830 constant pitch and filter coefficients. The volume coefficient is
1759     linearly interpolated inside a subfragment, unless
1760     --disable-interpolate-volume is set.)
1761 persson 696 - fine tuning of the EG modulation parameters
1762 persson 729 - improved filter cutoff calculation by adding support for the
1763     following gig parameters: Cutoff freq (used when no cutoff
1764     controller is defined), Control invert, Minimum cutoff, Velocity
1765 persson 791 curve and Velocity range. The keyboard tracking now scales
1766     cutoff frequency instead of resonance.
1767 persson 877 - added support for gig parameter Resonance.
1768 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1769 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1770     which can be overridden with --enable-global-attenuation
1771 persson 783 - EG fixes: made the length of "attack hold" stage more
1772     accurate. Release stage can now start before attack stage
1773 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1774     time now has a minimal value to prevent clicks.
1775 persson 799 - fixed pitch changes larger than one octave
1776 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1777     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1778     all modes can be altered via standard GM messages, that is CC5 for
1779     altering portamento time, CC65 for enabling / disabling portamento
1780     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1781 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1782     parameter) and crossfade
1783 persson 831 - added support for the "attenuation controller threshold" gig
1784     parameter
1785 persson 832 - added smoothing of volume changes caused by control change
1786     messages
1787 persson 865 - sample loop parameters are now taken from the DimensionRegion
1788     instead of the wave chunk
1789     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1790     not equal to a power of two
1791 persson 877 - reimplementation of the filter algorithm. The new filter is more
1792     accurate and supports all gig filter types, including bandreject
1793     and lowpass turbo.
1794 persson 903 - real support for 24 bit samples - samples are not truncated to
1795     16 bits anymore
1796     - support for aftertouch (channel pressure, not polyphonic
1797     aftertouch)
1798 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1799     amplifying from 0)
1800 persson 696
1801 schoenebeck 711 * LSCP server:
1802     - fixed application exit on broken pipe error (fixes bug #20)
1803 iliev 793 - fixed the notification messages delay due to lack of
1804     network activity (fixes bug #26)
1805 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1806     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1807 schoenebeck 711
1808 schoenebeck 838 * audio driver:
1809     - added aRts audio output driver (by no means RT safe)
1810    
1811 schoenebeck 775 * MIDI driver:
1812     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1813     messages several times instead of once
1814 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1815     for events (i.e. for offline rendering based MIDI drivers)
1816 persson 922 - added checks for bad MIDI data
1817 schoenebeck 775
1818 schoenebeck 900 * linuxsampler application:
1819     - show available sampler engine types on startup
1820    
1821 schoenebeck 705 * general changes:
1822     - support for muting sampler channels and solo mode of the same, two new
1823     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1824     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1825     introduced for this, the behavior is the same like on a mixer console
1826 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1827     --enable-process-muted-channels which can be used to enable the
1828     processing of muted channels.
1829 iliev 777 - support for sostenuto pedal
1830 iliev 779 - support for monitoring the total number of active voices
1831 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1832     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1833 persson 835 - fixed some memory management errors
1834 persson 841 - fixed some concurrency problems that could lead to crashes when
1835     LSCP commands were executed
1836 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1837     sampler channel (fixes bug #36)
1838 schoenebeck 705
1839 schoenebeck 692 Version 0.3.3 (15 July 2005)
1840 schoenebeck 686
1841     * packaging changes:
1842     - fixed compilation with gcc 4.0
1843    
1844 schoenebeck 687 * Gigasampler format engine:
1845     - LFO preprocessing was performed even though the respective LFO was
1846     disabled by the instrument patch (minor efficiency fix)
1847 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1848     for volume ramp downs in the same fragment (needed for current voice
1849     stealing implementation) then simply inform the user with a warning
1850     about possible click sounds and reduce the volume ramp down
1851     appropriately instead of cancelling the audio device connection
1852 schoenebeck 687
1853 schoenebeck 677 Version 0.3.2 (24 June 2005)
1854 schoenebeck 609
1855     * packaging changes:
1856     - updated autotools build files to compile on OS X
1857     (conditional compilation of CoreMIDI and MidiShare drivers)
1858 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1859     './configure --disable-asm' (definitely not recommended)
1860 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1861     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1862     (due to 'dist-bzip2' automake option)
1863 schoenebeck 649
1864     * Gigasampler format engine:
1865     - support for the gig parameters for "release velocity response" curves
1866     - fine tuning of the EGADSR envelope
1867     - volume of release triggered samples now depends on note-on velocity,
1868     note length and gig parameter "release trigger decay" instead of
1869     note-off velocity.
1870 schoenebeck 663 - revised voice stealing
1871     (fixes crash and endless loop caused by voice stealing)
1872 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1873 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1874     instead of when the respective voice is actually launched
1875     (fixes undefined behavior if stolen voices belonged to a key group -
1876     this case was followed by a "killed voice survived" error message)
1877 schoenebeck 669 - fixed minor issue with null/silence samples
1878     (those stole voices even though they don't need a voice at all which
1879     resulted in "voice stealing didn't work out" messages)
1880 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1881     instrument or audio output device change
1882 schoenebeck 654
1883 schoenebeck 620 * LSCP server:
1884 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1885 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1886 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1887 schoenebeck 609
1888 schoenebeck 668 * linuxsampler application:
1889     - added command line parameters --lscp-addr and --lscp-port to override
1890     default IP address and port of LSCP server
1891    
1892 schoenebeck 579 Version 0.3.1 (24 May 2005)
1893    
1894     * initial release
