* Gig engine: changed LFO start levels; LFO1 and LFO2 both to mid,
  LFO3 to max. start level (see discussion "GigaStudio LFO  
  compatibility" on mailing list from 2019-09-26 for details).
* Bumped version (2.1.1.svn20).

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

366 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
367     - Added new API method ScriptVM::syntaxHighlighting() which provides

371     - Extended parser issues to provide not only first line and first
372     column, but also last line and last column of issue (thus marking

374 schoenebeck 2902 - Reload script automatically after being modified by an instrument
375     editor.
376 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies

388     and ".not.".
389     - NKSP language scanner: Fixed IDs matching to require at least one
390     character (i.e. when matching function names or variable names).
391     - NKSP language scanner: disabled unusued rules.
392 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
393     be distinguished engine internally from "real" MIDI note on/off

407     - Implemented built-in script variable "$NI_CALLBACK_ID".
408     - Implemented built-in script variable "$NI_CALLBACK_TYPE".

420 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
421     synthesis parameter changes immediately in case the respective note
422     was triggered at the same time, instead of scheduling the parameter
423     change, especially because it would cause some parameter types's
424     changes either to be ramped (i.e. change_vol()) or other types even

431     was loaded.
432     - NKSP built-in wait() script function: abort script execution if
433     a negative or zero wait time was passed as argument (since this is
434     a common indication of a bug either of the script or even of the
435     engine, which could lead to RT instability or even worse).
436 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
437     threatening scripts.
438 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.

454     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
455     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
456 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
457     of its possible parameter selections.
458     - Added built-in script function "set_event_par()" and implemented some
459     of its possible parameter selections.
460 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
461 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
462 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
463     built-in function "ignore_controller()".
464 schoenebeck 3214 - Implemented built-in script function "change_velo()".
465     - Implemented built-in script function "change_note()".
466 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
467     intuitive behavior if used in combination with "change_vol_time()" or
468     "change_tune_time()" respectively: now tuning/volume changes are only
469     assigned (without delay) immediately to a new note if the respective
470     timing function has not been called before, otherwise the volume/tuning
471     changes are automatically faded (before, only the event's time stamp was
472     relevant).
473 schoenebeck 3221 - Implemented built-in script function "array_equal()".
474     - Implemented built-in script function "search()".
475     - Implemented built-in script function "sort()".

477 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
478     available for gig format engine).
479 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
480     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
481     - Implemented built-in script function "change_vol_curve()".
482     - Implemented built-in script function "change_tune_curve()".
483 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
484     offset with argument 3, where special value -1 means to use the regular
485     sample offset as defined by the instrument file.
486 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
487     - Built-in variable $EVENT_NOTE is now a read-only variable.
488     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
489     - built-in "play_note()" function now accepts -2 for its fourth argument
490     (note duration) which means the life time of the note shall be sticked
491     to the requested note number of argument 1.
492     - Fix: built-in "play_note()" function now returns 0 as result value if
493     -1 was passed for its fourth argument (note duration) and the respective
494     parent note is already gone.
495 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
496 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

504 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
505     "init" event handlers.
506 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
507     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
508     to retrieve all code blocks filtered out by the preprocessor.
509 schoenebeck 3293 - Added built-in script function "fork()".
510     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
511     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
512     - Fixed potential crash when accessing dynamic built-in array variables.
513 schoenebeck 3296 - Added built-in script function "callback_status()".
514     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
515     - Added built-in constant $CALLBACK_STATUS_QUEUE.
516     - Added built-in constant $CALLBACK_STATUS_RUNNING.
517 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
518     "change_decay()" and "change_release()" to i.e. allow passing 2000000
519     for doubling the respective time.
520 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
521     to a lexer start condition stack underrun.
522     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
523     USE_CODE_IF_NOT() preprocessor statements.
524 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
525     can be set to disable all subsequent built-in "message()" function calls
526     on preprocessor level.
527 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
528 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
529     to avoid the editor app to crash on ill-formed text input.
530 schoenebeck 3335 - Added built-in script function "change_pan_time()".
531     - Added built-in script function "change_pan_curve()".

533     - Added built-in script function "change_cutoff_decay()".
534     - Added built-in script function "change_cutoff_sustain()".
535     - Added built-in script function "change_cutoff_release()".
536     - Added built-in script function "change_cutoff_lfo_depth()".
537     - Added built-in script function "change_cutoff_lfo_freq()".
538 schoenebeck 2871
539 schoenebeck 3050 * Instruments DB:
540     - Fixed memory access bug of general DB access code which lead to
541     undefined behavior.
542 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
543     - The instrument DB path of linuxsampler's --create-instruments-db argument
544     is now optional, if it is missing, then a default location is used.
545 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
546     - Added support for scanning Sound Font (.sf2) files.
547 schoenebeck 3101 - Fixed undefined DB transaction behavior.

559 persson 2203 - another "make dist" fix, for the LV2 plugin
560 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
561 persson 2197 - minor Makefile fix for building lscpparser when build and source
562     directories are separate
563 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

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

695     - added v1 LFO opcodes to parser (no support in engine yet)
696 persson 2082 - added support for amp_veltrack and amp_velcurve_N
697     - fine-tuned the default velocity curve
698 persson 2086 - added support for transpose
699     - fixed crash when using sw_down/up
700     - improved logic for sw_lokey/hikey/up/down/last
701     - added more v1 aliases to parser
702 persson 2091 - reduced memory usage for sfz data
703 persson 2101 - RT-safeness: avoid malloc in audio thread
704     - fixed a bug that could cause voice stealing to fail
705 persson 2106 - optimized sample lookup
706 persson 2114 - improved support for exclusive groups (group, off_by and
707     off_mode)

709     - added support for loop_mode=one_shot
710 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs
711     - added support for Ogg Vorbis sample files
712 persson 2167 - use loop markers from sample file if loop_start and loop_end are
713     not set in sfz file
714 persson 2175 - implemeted filters. Filter types: lowpass, bandpass, bandreject
715     and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
716     cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
717     cutoff_cc, cutoff_chanaft.
718     - bugfix: zero ampeg_sustain didn't work
719 persson 2176 - added support for velocity effect on amplifier envelope time
720     (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
721     ampeg_vel2release)
722 persson 2203 - added support for EG hold (ampeg_hold)
723 iliev 2216 - added support for sample offset (offset)

1042 schoenebeck 2123 channel to a different engine type
1043 persson 2127 - fixed crash when deleting a sampler channel or changing engine
1044     type while an instrument load was in progress
1045 persson 2162 - bugfix: playing a note while changing the instrument could cause
1046     a crash, or give "Handing back unknown region" error messages
1047 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
1048     refresh) could cause instruments to be unloaded
1049 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
1050     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1051 persson 2185 - Mac OS X: fixed hanging threads
1052 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
1053     it caused hanging threads on Windows
1054 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
1055     after MIDI/audio device creation failure
1056 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1057     instruments were uselessly precached with zero samples, however it still
1058     took the full preloading time and on 1st program change the respective
1059     instrument was completely reloaded again.
1060 persson 2277 - fixed handling of rapid bank select and program change messages
1061     sent to the same sampler channel (patch from the Open Octave
1062     project, slightly adjusted)

1079     (labelled "Disk stream not available in time")
1080 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
1081     crashes and noise on such transitions).
1082 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1083     (fixes #208)
1084 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1085     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1086     practically irrelevant, however it caused problems with the new LSCP
1087     shell's auto completion feature).
1088 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1089     after each other (fixes #231).

1117 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
1118     plugin DLL on Windows systems failed
1119 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1120     - optimized the SynchronizedConfig class so it doesn't wait
1121     unnecessarily long after an update
1122 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
1123     events (e.g. to highlight the pressed keys on the virtual keyboard
1124     of gigedit)
1125 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
1126 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
1127 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1139 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
1140     be switched on by command line option "--stacktrace" (the automatic
1141     stacktrace mechanism seems to be broken on most systems at the moment)
1142 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1143     a pointer to the launched InstrumentEditor object
1144 schoenebeck 1876 - added optional 3rd party user data parameter for following
1145     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1146     InstrumentEditor::Launch(),

1168 persson 1888 - applied old fixes to the ASIO driver that were included in the
1169     previous binary release but accidentally never committed to CVS
1170     (fixes #117)
1171 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

1179     stereo
1180 persson 1922 - added channel routing, fxsends and midi maps to the settings
1181     stored in the plugin state
1182 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
1183     AudioChannel::CopyTo() methods using GCC vector exensions

1187 schoenebeck 1599
1188 persson 1651 * MIDI driver:
1189     - added JACK MIDI driver
1190 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

1192     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1193 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1194 persson 1887 CoreMidi or AU
1195 persson 1889 - fixed mingw-w64 compilation error in MME driver
1196 persson 1924 - made program change handling in MIDI thread real-time safe by
1197     moving the logic to a non-RT thread
1198 persson 1951 - fixed minor memory leak in ALSA driver
1199 persson 1651
1200 schoenebeck 1604 * instruments database:
1201 iliev 1603 - avoid time consuming samples scanning when adding instruments
1202     to the instruments database
1203 iliev 1727 - added support for handling lost files in the instruments database
1204 iliev 1781 - Implemented option for adding instruments in separate directories
1205     in the instruments database

1207 persson 1908 - work-around for missing fnmatch function on Windows to make
1208     instrument database compilable
1209 schoenebeck 1930 - added instrument database support on Windows
1210     works with both standalone mode and VST plugin.
1211     the instruments DB file is located in
1212     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1213     databases for each windows user
1214     if no DB is present it automatically creates the .linuxsampler subdir
1215     and then creates an empty DB
1216 persson 1943 - fixed recursive import, which was broken on Windows
1217 iliev 1603
1218 persson 1644 * Gigasampler format engine:
1219     - fixed a memory leak that could happen when a channel was deleted
1220     while notes were playing
1221 persson 1646 - made it possible to load an instrument even if the audio thread
1222     isn't running
1223 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1224     enough for piano gigs with pedal noise samples
1225 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1226     respective FX send MIDI controller was used
1227 schoenebeck 1724 - added support for GM global device volume SysEx message
1228 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1229     whole sampler [default] or only to the sampler channels that are
1230     connected to the respective MIDI input port the SysEx message arrived
1231     on)
1232 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1233     sometimes wrongly killed in the same buffer, causing no sound to
1234     be played
1235 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1236     which is usally used to switch a part between chromatic sounds and
1237     drumkit sounds (as opposed to their common default setting of MIDI
1238     part 10 being a drumkit part and all other ones chromatic parts), in
1239     LS however one can switch between the first 16 MIDI instrument maps
1240     defined for the sampler
1241 persson 1764 - made it possible to create multiple sample channels even if the
1242     audio thread isn't running
1243 persson 1844 - fixed crash when removing channel with active voices (#116)
1244 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1245     un-cache the respective sample if it's really not used by any
1246     sampler engine anymore
1247     - re-cache samples in case they were changed by an instrument editor,
1248     e.g. when a sample was added while playing (#82)
1249 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1250     same time stamp as the voice's note-on event and occured both in the
1251     same audio fragment cycle (fixes bug #112)
1252 persson 1858 - added support for the "fine tune" and "pitch bend range"
1253     instrument-level gig parameters
1254     - fixed minor artifacts in pitch bend handling
1255 schoenebeck 1860 - added support for GS Reset SysEx message
1256 persson 1862 - allow gig files to use unlimited downward pitch shifting
1257     - added a limit check for upward pitch shifting
1258 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1259     note was silent
1260 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1261     same time a new instrument was loading
1262 persson 1644
1263 schoenebeck 1687 * LSCP server:
1264     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1265     react on MIDI data arriving on certain sampler channels (so far only
1266     Note-On and Note-Off events are sent via this LSCP event)
1267 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1268     react on MIDI data arriving on certain MIDI input devices (so far only
1269     Note-On and Note-Off events are sent via this LSCP event)
1270 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1271     SET DB_INSTRUMENT FILE_PATH
1272 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1273     frontends to send MIDI messages to specific sampler channel
1274     - added two additional fields to GET FILE INSTRUMENT INFO command -
1275     KEY_BINDINGS and KEYSWITCH_BINDINGS
1276 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1277     was incorrect
1278 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1279 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1280     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1281     be triggered respectively
1282     - added new LSCP command "SET STREAMS" to globally alter the maximum
1283     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1284     which will be triggered respectively
1285 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1286     a gigedit file dialog is opened)
1287 iliev 1848 - close all connections when LSCPServer is deleted
1288 iliev 1882 - hard close of all sockets on exit
1289 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1290     driver
1291 schoenebeck 1687
1292 iliev 1761 * Bug fixes:
1293     - fixed a crash which occurs when removing a sampler channel waiting
1294     to start instrument loading after another channel
1295 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1296     instrument loading in progress (bug #113)
1297 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1298     instrument with PERSISTENT load mode
1299 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1300     - fixed memory leaks when issuing the following LSCP commands:
1301     GET AUDIO_OUTPUT_DRIVER INFO
1302     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1303     GET MIDI_INPUT_DRIVER INFO
1304     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1305     - fixed possible compilation error when sqlite is not present
1306 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1307 iliev 1847 - fixed crash when changing the audio output device of a sampler
1308     channel with loaded instrument and start playing notes
1309 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1310 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1311     PowerPC, which probably could cause crashes on that platform
1312 persson 1889 - fixed a memory management error which could cause a crash when a
1313     plugin was unloaded
1314 persson 1896 - bugfix: two private structs had the same name, which could cause
1315     problems if the linker chose the wrong constructor
1316 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1317     Windows
1318 iliev 1761

1320 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1321 schoenebeck 1454
1322     * packaging changes:
1323     - added autoconf checks for pthread library
1324     - added autoconf check for pthread bug found on certain NPTL-enabled
1325     glibc versions (see Gentoo bug report #194076)
1326 senoner 1502 - added autoconf checks for MS Windows
1327 schoenebeck 1454
1328 persson 1455 * general changes:
1329     - bugfix: the thread used by an editor plugin didn't die when the
1330     editor closed
1331 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1332     out all the space. operator--() did not apply size_mask after
1333     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1334     order to avoid problems with the _NonVolatileReader functions.
1335     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1336     GetWriteSpace(). Since this function is currently only used in
1337     the stream's qsort() compare function, it didn't trigger any
1338     bugs.
1339     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1340     24bit mode too. Faster method to read 24bit words on little
1341     endian machines (x86): replaced 3 byte reads + shifts with a 1
1342     unaligned 32bit read and shift
1343     - experimental support for MS Windows (MIDI input via MME, AUDIO
1344     output via ASIO)
1345     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1346 iliev 1541 - support for monitoring the total number of active disk streams
1347     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1348     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1349 persson 1455
1350 senoner 1500 * AUDIO driver:
1351 persson 1534 - added Windows ASIO low latency audio driver
1352 senoner 1500
1353 senoner 1485 * MIDI driver:
1354 schoenebeck 1495 - added MME Windows MIDI driver
1355 senoner 1485
1356 schoenebeck 1471 * LSCP server:
1357     - added support for Windows style path / filenames, however with
1358     forward slash path separators instead of backslash
1359     (i.e. "C:/foo/bar.gig")
1360 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1361     apostrophes as well
1362 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1363     "LIST FILE INSTRUMENTS <file>" and
1364     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1365     about an arbitrary instrument file on the system where the sampler is
1366     running on
1367 schoenebeck 1471
1368 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1369 schoenebeck 947
1370 schoenebeck 1065 * packaging changes:
1371 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1372     API header files anymore
1373 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1374     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1375 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1376     capable to execute our autoconf environment, thus no need anymore
1377     to maintain the compile time configuration file (osx/version.h) for
1378     OSX manually (patch by Toshi Nagata)
1379 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1380     parameters
1381 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1382     C++ API header files, all implementation internal global definitions
1383     are now in global_private.h
1384     - atomic.h is not exposed to the C++ API anymore
1385     - no need to include config.h anymore for using LS's API header files
1386     - fixed warnings in API doc generation
1387 schoenebeck 1065
1388 schoenebeck 947 * general changes:
1389     - replaced the old, confusing MIDI program change mechanism by a
1390     flexible MIDI instrument mapper which allows to map arbitrary
1391 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1392 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1393     loaded on the respective channel when such MIDI program change
1394     messages arrive, beside that, each entry allows to define a life-time
1395     strategy for the instrument, so the user can define whether the
1396     instrument should i.e. be permanently loaded (to be able to switch
1397     quickly among sounds) or i.e. loaded just on demand when the
1398     respective program change arrives (to safe RAM space), as well as a
1399     global volume factor for each entry, so the user can adjust the volume
1400     dynamic of his mapped instrument collection without having to modify
1401 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1402     MIDI instrument maps and assign each sampler channel individually
1403     a certain map, so that i.e. separation of normal instruments and
1404     drumkits is possible
1405 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1406     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1407 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1408     due to a constant size RingBuffer FIFO which is now replaced by a
1409     dynamic (unlimited) size std::list FIFO
1410 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1411     output channels for being processed by external effect processors
1412     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1413     controllers
1414 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1415 iliev 1130 - Implemented new, improved notification system
1416 schoenebeck 1149 - fixed compilation errors regarding OSX
1417     (patch by Toshi Nagata)
1418 iliev 1161 - implemented instruments database
1419 iliev 1345 - added support for escape sequences to the instruments database
1420 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1421     within the sampler's process (by using instrument editor plugins),
1422     you'll notice the new "Registered instrument editors:" message on
1423 schoenebeck 1407 startup, added a new LSCP command:
1424     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1425 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1426     given sampler channel, the plugin path can be overridden at compile
1427     time with ./configure --enable-plugin-dir=/some/dir
1428 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1429     in the sampler's process to safely edit instruments while playing
1430     without a crash (hopefully) by either suspending single regions
1431     wherever possible or if unavoidable whole engine(s)
1432 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1433     policy and priority on thread level, set a minimum stack size for
1434     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1435     threads simply inherited properties of starting thread instead of
1436     setting their own policy and priority
1437 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1438     main process did not wait for the stack trace process to finish
1439     its output
1440 persson 1248 - fixed some minor memory leaks
1441 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1442     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1443 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1444     register, to avoid relocations in the text segment at runtime)
1445 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1446 schoenebeck 947
1447     * MIDI driver:
1448     - dispatch bank select (MSB and LSB) messages
1449    
1450 schoenebeck 1049 * audio driver:
1451     - the ALSA audio output driver parameters now reflect the correct
1452     parameter value ranges for the respective selected sound card
1453     (patch by Till Wimmer, a bit fixed and extended)
1454    
1455 persson 951 * Gigasampler format engine:
1456     - if a filter is used and EG2 finishes before EG1, let the voice
1457     die when EG2 has finished (this fixes a problem with clicks and
1458     voice starvation for some gigs)
1459 persson 1038 - playback is no longer disabled during instrument loading
1460     - all notes playing on a channel that changes its instrument keep
1461     playing with the old instrument until they get a note off
1462     command
1463 persson 1039 - EG fix: a release value of zero could cause noises or crash
1464 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1465 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1466     above max sustain level, which means that there is a decay phase
1467     even if sustain is 100%
1468 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1469     noises or crashes
1470 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1471 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1472     supplied to the configure script (fixes #46)
1473 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1474     instead of a fix value
1475 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1476     127 (solo mode) only kill voices if the respective mode really
1477     changed
1478 persson 951
1479 schoenebeck 1244 * LSCP server:
1480     - fixed compile time error for old Bison versions
1481     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1482 schoenebeck 1245 - parser now supports extended ASCII character set
1483     (up to ASCII code 255, i.e. includes now umlauts and accents)
1484     - filename arguments in LSCP commands now allow to use escape
1485     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1486     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1487     code value like \xf2) (fixes bug #24)
1488 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1489     least one of their text-based parameters (i.e. name, description):
1490     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1491     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1492     "SET DB_INSTRUMENT_DIRECTORY NAME",
1493     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1494     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1495     "FIND DB_INSTRUMENT_DIRECTORIES"
1496 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1497     occured, the unexpected character and the actually expected, possible
1498     character(s), the latter only if less than 5 possibilities)
1499 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1500     settings
1501 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1502     of strings were treated as being one string containing commas
1503     (fixes #57)
1504 schoenebeck 1244
1505 iliev 959 * Bug fixes:
1506     - fixed crash occurring on certain LSCP scripts (Bug 39)
1507 persson 1038 - another thread safety fix for lscp "load engine" and "set
1508     channel audio output device"
1509 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1510     on a sampler channel with connected MIDI device
1511 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1512     device connected to a sampler channel to number less then or equal
1513     to the index of the port to which the sampler channel is connected.
1514 iliev 1296 - The previous bindings were not been disconnected when altering
1515     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1516     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1517 iliev 1297 - The active stream/voice count statistic was incorrect.
1518 iliev 1298 - notification events were not been sent for some sampler
1519     channel changes
1520 iliev 1305 - added default min and max values to restrict the number of allowed
1521     audio output channels and MIDI input ports
1522 iliev 1306 - the connection to the PCM interface is now closed when destroying
1523     an audio output device
1524 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1525 iliev 959
1526 schoenebeck 1221 * test cases:
1527     - updated and fixed (haven't been touched in a while)
1528    
1529 schoenebeck 937 Version 0.4.0 (24 November 2006)
1530 persson 696
1531 schoenebeck 697 * packaging changes:
1532 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1533     to post-(un)install steps; added devel package for liblinuxsampler;
1534     to linuxsampler.spec (RPM)
1535 schoenebeck 697 - install necessary development header files for allowing 3rd party
1536     applications to link against liblinuxsampler
1537     - liblinuxsampler's API documentation can be generated with 'make docs'
1538     (Doxygen required)
1539 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1540     implementation (currently either an integer math solution or a
1541     di-harmonic approximation), automatic detection can be overriden
1542     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1543     configure script argument though (mandatory for cross-compilation)
1544 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1545     provided some on his own (as CXXFLAGS)
1546 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1547     messages
1548 schoenebeck 852 - added compile time options to allow disabling the various audio and
1549     MIDI drivers
1550 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1551     (patch by Ebrahim Mayat)
1552 schoenebeck 697
1553 persson 696 * Gigasampler format engine:
1554 schoenebeck 738 - extensive synthesis optimization
1555     (reimplementation of EGs and LFO(s), removed synthesis parameter
1556     prerendering and the synthesis parameter matrix in general, splitting
1557     each audio fragment into subfragments now where each subfragment uses
1558 persson 830 constant pitch and filter coefficients. The volume coefficient is
1559     linearly interpolated inside a subfragment, unless
1560     --disable-interpolate-volume is set.)
1561 persson 696 - fine tuning of the EG modulation parameters
1562 persson 729 - improved filter cutoff calculation by adding support for the
1563     following gig parameters: Cutoff freq (used when no cutoff
1564     controller is defined), Control invert, Minimum cutoff, Velocity
1565 persson 791 curve and Velocity range. The keyboard tracking now scales
1566     cutoff frequency instead of resonance.
1567 persson 877 - added support for gig parameter Resonance.
1568 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1569 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1570     which can be overridden with --enable-global-attenuation
1571 persson 783 - EG fixes: made the length of "attack hold" stage more
1572     accurate. Release stage can now start before attack stage
1573 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1574     time now has a minimal value to prevent clicks.
1575 persson 799 - fixed pitch changes larger than one octave
1576 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1577     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1578     all modes can be altered via standard GM messages, that is CC5 for
1579     altering portamento time, CC65 for enabling / disabling portamento
1580     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1581 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1582     parameter) and crossfade
1583 persson 831 - added support for the "attenuation controller threshold" gig
1584     parameter
1585 persson 832 - added smoothing of volume changes caused by control change
1586     messages
1587 persson 865 - sample loop parameters are now taken from the DimensionRegion
1588     instead of the wave chunk
1589     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1590     not equal to a power of two
1591 persson 877 - reimplementation of the filter algorithm. The new filter is more
1592     accurate and supports all gig filter types, including bandreject
1593     and lowpass turbo.
1594 persson 903 - real support for 24 bit samples - samples are not truncated to
1595     16 bits anymore
1596     - support for aftertouch (channel pressure, not polyphonic
1597     aftertouch)
1598 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1599     amplifying from 0)
1600 persson 696
1601 schoenebeck 711 * LSCP server:
1602     - fixed application exit on broken pipe error (fixes bug #20)
1603 iliev 793 - fixed the notification messages delay due to lack of
1604     network activity (fixes bug #26)
1605 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1606     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1607 schoenebeck 711
1608 schoenebeck 838 * audio driver:
1609     - added aRts audio output driver (by no means RT safe)
1610    
1611 schoenebeck 775 * MIDI driver:
1612     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1613     messages several times instead of once
1614 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1615     for events (i.e. for offline rendering based MIDI drivers)
1616 persson 922 - added checks for bad MIDI data
1617 schoenebeck 775
1618 schoenebeck 900 * linuxsampler application:
1619     - show available sampler engine types on startup
1620    
1621 schoenebeck 705 * general changes:
1622     - support for muting sampler channels and solo mode of the same, two new
1623     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1624     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1625     introduced for this, the behavior is the same like on a mixer console
1626 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1627     --enable-process-muted-channels which can be used to enable the
1628     processing of muted channels.
1629 iliev 777 - support for sostenuto pedal
1630 iliev 779 - support for monitoring the total number of active voices
1631 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1632     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1633 persson 835 - fixed some memory management errors
1634 persson 841 - fixed some concurrency problems that could lead to crashes when
1635     LSCP commands were executed
1636 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1637     sampler channel (fixes bug #36)
1638 schoenebeck 705
1639 schoenebeck 692 Version 0.3.3 (15 July 2005)
1640 schoenebeck 686
1641     * packaging changes:
1642     - fixed compilation with gcc 4.0
1643    
1644 schoenebeck 687 * Gigasampler format engine:
1645     - LFO preprocessing was performed even though the respective LFO was
1646     disabled by the instrument patch (minor efficiency fix)
1647 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1648     for volume ramp downs in the same fragment (needed for current voice
1649     stealing implementation) then simply inform the user with a warning
1650     about possible click sounds and reduce the volume ramp down
1651     appropriately instead of cancelling the audio device connection
1652 schoenebeck 687
1653 schoenebeck 677 Version 0.3.2 (24 June 2005)
1654 schoenebeck 609
1655     * packaging changes:
1656     - updated autotools build files to compile on OS X
1657     (conditional compilation of CoreMIDI and MidiShare drivers)
1658 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1659     './configure --disable-asm' (definitely not recommended)
1660 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1661     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1662     (due to 'dist-bzip2' automake option)
1663 schoenebeck 649
1664     * Gigasampler format engine:
1665     - support for the gig parameters for "release velocity response" curves
1666     - fine tuning of the EGADSR envelope
1667     - volume of release triggered samples now depends on note-on velocity,
1668     note length and gig parameter "release trigger decay" instead of
1669     note-off velocity.
1670 schoenebeck 663 - revised voice stealing
1671     (fixes crash and endless loop caused by voice stealing)
1672 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1673 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1674     instead of when the respective voice is actually launched
1675     (fixes undefined behavior if stolen voices belonged to a key group -
1676     this case was followed by a "killed voice survived" error message)
1677 schoenebeck 669 - fixed minor issue with null/silence samples
1678     (those stole voices even though they don't need a voice at all which
1679     resulted in "voice stealing didn't work out" messages)
1680 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1681     instrument or audio output device change
1682 schoenebeck 654
1683 schoenebeck 620 * LSCP server:
1684 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1685 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1686 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1687 schoenebeck 609
1688 schoenebeck 668 * linuxsampler application:
1689     - added command line parameters --lscp-addr and --lscp-port to override
1690     default IP address and port of LSCP server
1691    
1692 schoenebeck 579 Version 0.3.1 (24 May 2005)
1693    
1694     * initial release
