Added new LFO implementations:

* Added int math square LFO implementation.

* Added int math saw LFO implementation.

* Added numeric complex nr sine LFO implementation.

* Added public API C++ class "LFO", which is a cluster class
  encapsulating all the sampler's LFO implementations to be used by
  3rd party applications (e.g. by Gigedit).

* Marked class LFOTriangleDiHarmonic as deprecated
  (will be removed in future).

* Added LFOAll.h which includes all LFO implementation's header files.

* Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
  algorithm (since result of 2nd run was not accumulated).

* Added benchmark for saw wave (benchmarks/saw.cpp).

* Added benchmark for sine wave (benchmarks/sine.cpp).

* Added benchmark for square wave (benchmarks/square.cpp).

* Increased amount of benchmarks runs by factor 6 to achieve benchmark

* Bumped version (2.1.1.svn18).

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 3550
23 schoenebeck 3551 * Real-time instrument scripts:
24     - Added method ScriptVM::setExitResultEnabled() which allows to
25     explicitly enable the built-in exit() function to optionally accept
26     one function argument; the value of the passed exit() function
27     argument will then become available by calling
28     VMExecContext::exitResult() after script execution.
29 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
30 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
31     with a regular character (a-z or A-Z); starting them with a digit or
32     underscore is not allowed.
33     - NKSP parser fix: equal comparison operator "=" and not equal comparison
34     operator "#" must only accept integer operands.
35     - NKSP language: Implemented support for standard units like Hertz, seconds,
36     Bel including support for metric unit prefixes; so one can now e.g.
37     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
38     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
39     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
40     - NKSP language: Introduced "final" operator "!" which is specifically
41     intended for synthesis parameter values to denote that the synthesis
42     parameter value is intended to be the "final" value for that synthesis
43     parameter that should explicitly be used by the engine and thus causing
44     the sampler engine to ignore all other modulation sources for the same
45     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
46     variable or formula with this new "!" operator the expression is marked as
47     being "final".
48 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
49     and their potential metric prefix token.
50 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
51     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
52     - NKSP language: Added support for NKSP real number (floating point) script
53     variables (declare ~foo).
54     - NKSP language: Added support for NKSP real number (floating point) array
55     script variables (declare ?foo[]).
56     - Built-in script function "message()" accepts now real number argument as
57     well.
58     - Added built-in script function "real_to_int()" and its short hand form
59     "int()" for casting from real number to integer in NKSP scripts.
60     - Added built-in script function "int_to_real()" and its short hand form
61     "real()" for casting from integer to real number in NKSP scripts.
62 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
63     argument as well.
64 schoenebeck 3577 - Built-in script functions may have a different return type depending on
65     the arguments passed to the function.
66     - Built-in script function "abs()" optionally accepts and returns real
67     number.
68     - Built-in script functions "min()" and "max()" optionally accept real
69     number arguments and return real number as result in that case.
70 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
71     built-in functions (added methods VMFunction::returnUnitType() and
72     VMFunction::returnsFinal() for that purpose which must be implemented by
73     built-in function implementations).
74     - NKSP language: Allow metric unit prefixes of numeric scalar and array
75     variables to be changed freely at runtime (unlike unit types like Hz etc.
76     which are still sticky, parse-time features of variables which cannot be
77     changed at runtime for the intentional sake of determinism).
78     - NKSP language: 'final' values are prohibited for array variables for now
79     (attempt causes a parsers error).
80     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
81     conditions of runtime control structures like if(), while(), select()
82     (attempt causes a parser error).
83     - NKSP VM API: Allow built-in functions to perform their own, individual
84     parse time checks of arguments going to be passed to the function at
85     runtime (added method VMFunction::checkArgs() for that purpose).
86     - NKSP language: raise parser warning if only one operand of binary
87     operators (like logical 'or' comparison) contain a 'final' value (because
88     it would always yield in a 'final' result in such cases).
89     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
90     different metric unit prefixes, which will behave as expected (e.g.
91     result of expression '1000us < 2ms' is true).
92     - NKSP language: Allow adding values with different metric unit prefixes
93     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
94     - NKSP language: Allow subtracting values with different metric unit
95     prefixes (e.g. result of expression '1ms - 20us' is '980us').
96     - NKSP language: Allow multiplying with any metric unit prefixes
97     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
98     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
99     we don't have any considerable practical use for a term like '4s^2'
100     (hence any attempt multiplying two unit types still causes parser error).
101     - NKSP language: Allow dividing by any metric unit prefixes and allow
102     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
103     yields in unit free result '8'). So this is now a way to cast units away
104     e.g. for passing the result to other expressions, certain function calls
105     or variables which are not accepting any units (or that specific unit).
106     - NKSP language: integer arrays and real number arrays can now be converted
107     to strings (e.g. for dumping their content with message() calls for
108     script debugging purposes).
109     - NKSP language: expressions and variables with units are now correctly
110     casted to strings (e.g. with message() calls).
111     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
112     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
113     floating point tolerances into account.
114     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
115     VMScalarNumberExpr::evalCastReal().
116     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
117     'VMIntArrayExpr' and 'VMRealArrayExpr'.
118     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
119     unitFactor() (runtime) methods.
120     - Built-in function "exit()" supports now returning units and 'final'ness
121     for test cases.
122     - The following built-in functions support now units as well: "abs()",
123     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
124     "real_to_int()", "int()", "int_to_real()" and "real()".
125     - Built-in functions "array_equal()", "search()" and "sort()" support now
126     real number arrays (correctly) as well.
127     - Added individual parse time checks of arguments to be passed to built-in
128     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
129     "array_equal()" and "search()" specific for their individual purposes.
130 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
131     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
132     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
133     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
134     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
135     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
136     isScalarNumber() -> isNumber()).
137 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
138     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
139     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
140     as convenient methods for automatically converting values to expected
141     metric value basis.
142     - Built-in function "wait()" accepts now both integers and real numbers as
143     argument.
144 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
145     VMFunction::argType(vmint iArg) which was already superseded by its new
146     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
147     - NKSP parser: if wrong argument type was passed to a built-in function and
148     that built-in function accepts more than one data type for the argument,
149     then show all supported data types as parser error message.
150 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
151     unit type as well for its 3rd and 4th function arguments.
152     - The following built-in functions accept now real numbers as well for their
153     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
154     "change_attack()", "change_decay()", "change_release()",
155     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
156     "change_cutoff_sustain()", "change_cutoff_release()",
157     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
158     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
159     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
160     - Fixed built-in function "change_play_pos()" not having accepted metric
161     prefixes at all.
162 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
163     with unit type (for their 2nd argument) as if they were relative values
164     (that is as if they were passed without a unit type): "change_attack()",
165     "change_decay()", "change_release()", "change_cutoff_attack()",
166     "change_cutoff_decay()", "change_cutoff_release()".
167     - Fixed the following built-in functions having applied completely wrong
168     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
169     respective EGs being their modulation sink assume uint data type with
170     value range 0..1000 instead of 0.0..1.0.
171     - Added individual parse-time checks of function arguments for the following
172     built-in functions: "play_note()", "note_off()", "set_event_mark()",
173     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
174     "change_decay()", "change_release()", "change_cutoff_attack()",
175     "change_cutoff_decay()", "change_cutoff_release()",
176     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
178     "change_pan_time()".
179     - Don't abort function call if unit type was used and at the same time
180     'final' operator was omitted for the primary value argument of the
181     following built-in functions: "change_cutoff()", "change_attack()",
182     "change_decay()", "change_release()", "change_cutoff_attack()",
183     "change_cutoff_decay()", "change_cutoff_release()",
184     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
185     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
186     "change_pan_time()", instead imply 'final'ness at runtime and raise an
187     appropriate parser warning at parse time.
188 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
189     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
190     "cos()", "tan()", "asin()", "acos()", "atan()".
191     - Added built-in script real number constant "~NI_MATH_PI".
192     - Added built-in script real number constant "~NI_MATH_E".
193 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
194 schoenebeck 3551
195 schoenebeck 3550 * test cases:
196 schoenebeck 3548 - Fixed compiler errors in test cases.
197     - Updated README for how to compile & run test cases.
198     - Updated test case
199     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
200     expected behaviour of the Mutex class implementation (recursive
201     mutex type).
202 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
203     functions.
204 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
205 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
206     int_to_real(), real(), real_to_int() and int(), as well as for the
207     plus, minus and negate language operators.
208 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
209     'final' operator usage cases.
210     - Added NKSP test cases for (floating point tolerance aware) real number
211     equalness / unequalness comparison.
212 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
213     initialization of arrays.
214 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
215     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",

224     - Fixed support for regions with loccN/hiccN conditions on more than one
225     MIDI controller.
226    
227 schoenebeck 3612 * Benchmarks:
228     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
229     algorithm (since result of 2nd run was not accumulated).
230     - Added benchmark for saw wave (benchmarks/saw.cpp).
231     - Added benchmark for sine wave (benchmarks/sine.cpp).
232     - Added benchmark for square wave (benchmarks/square.cpp).
233     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
234     which are large enough on modern systems.
235    
236 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
237 schoenebeck 3381
238     * Real-time instrument scripts:
239     - Fixed behavior of built-in NKSP functions change_sustain(),
240     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
241     and change_cutoff_release().
242    
243 schoenebeck 3444 * general changes:
244     - Only play release trigger samples on sustain pedal up if this behaviour
245     was explicitly requested by the instrument (otherwise only on note-off).
246 persson 3455 - Fixed compiler warnings.
247     - Fixed compilation error when cross-compiling to Mac.
248 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
249     (see bug #169).
250     - LSCP doc: Be more clear describing the two distinct approaches
251     of using external vs. internal effects (see bug #169).
252 schoenebeck 3514 - "optional" class: Fixed comparison operators.
253 schoenebeck 3444
254 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
255     - Format extension: If requested by instrument then don't play release
256     trigger sample on note-off events.
257    
258 schoenebeck 3487 * SFZ format engine:
259     - Fixed memory leak when releasing samples
260     (fixes bug #307, patch by Jacek Roszkowski)
261 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
262     (fixes bug #308, patch by Jacek Roszkowski).
263 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
264     (fixes bug #310, patch by Jacek Roszkowski).
265 schoenebeck 3487
266 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
267 persson 2837
268 persson 2856 * SFZ format engine:
269     - added support for <global>, <master> and #define (patch by Alby M)
270 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
271     - Added support for sfz extension opcode 'script' which may be used to
272     load real-time instrument script file (NKSP script language).
273 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
274 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
275 persson 3291 - sfz parser: allow missing space between header and opcode
276 persson 2856
277 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
278 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
279     cutoff settings.
280 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
281     all if an up-pitch of more than 40 semi tones was requested (I don't
282     think there is any stock gig sound that requires this behavior to
283     resemble its original sound).
284 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
285     be aborted (as LinuxSampler extension to the original GigaStudio 4
286     format).
287 schoenebeck 3072
288 persson 2837 * general changes:
289     - fixed printf type errors (mostly in debug messages)
290 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
291 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
292     allowing to sort data efficiently in real-time safe manner.
293     - RTList class: added methods for moving/inserting elements to arbitrary
294     position within a list.
295     - RTList class: added method fromPtr() for creating an Iterator object from
296     a raw element pointer.
297     - Attempt to partly fix resetting engine channels vs. resetting engine, an
298     overall cleanup of the Reset*(), ConnectAudioDevice(),
299     DisconnectAudioDevice() API methods would still be desirable though,
300     because the current situation is still inconsistent and error prone.
301 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
302     being directly assigned to a keyboard key. This allows more fine graded
303     processing of voices, which is i.e. required for certain instrument
304     script features.
305 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
306     (CC #64) events.
307     - Fix: Release trigger voices can now also distinguish correctly between
308     note-off and sustain pedal up events.
309 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
310     (while slow rate of crossfade smoother is preserved) to allow quick
311     volume and pan changes by instrument scripts for instance.
312 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
313     properly and thus were ignored for certain uses.
314 schoenebeck 3018 - Added new C++ API method
315     VirtualMidiDevice::SendChannelPressureToSampler().
316 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
317     sub threads is 16-byte aligned
318 schoenebeck 3054 - fixed numerous compiler warnings
319 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
320 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
321     fixes potential undefined behavior.
322 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
323     have a valid sample mapped (fixes bug #252).
324     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
325 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
326     subsequent optional argument due to glibc's implementation oddity
327     which expects a "=" sign, but no space between them.
328 persson 2837
329 schoenebeck 2866 * packaging changes:
330     - removed unnecessary dependency to libuuid
331     (originated by libgig's usage of it)
332 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
333     auto detect whether it (sh/c)ould output its messages in color.
334 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
335     substitution variable.
336     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
337 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
338     linuxsampler with instruments DB support.
339 schoenebeck 2866
340 schoenebeck 2871 * Real-time instrument scripts:
341     - Implemented scheduler for delayed MIDI events and for suspended scripts.
342     - Built-in script function "wait()": implemented support for function's
343     "duration-us" argument, thus scripts using this function are now
344     correctly resumed after the requested amount of microseconds.
345     - Built-in script function "play_note()": implemented support for
346     function's "duration-us" argument, thus notes triggered with this
347     argument are now correctly released after the requested amount of
348     microseconds.
349     - Fix: script events were not cleared when engine channel was reset,
350     potentially causing undefined behavior.
351     - Fixed crash which happened when trying to reference an undeclared
352     variable.
353 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing

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

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

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

395     (i.e. "if end if").
396 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
397     - Implemented built-in script variable "$NI_CALLBACK_ID".
398     - Implemented built-in script variable "$NI_CALLBACK_TYPE".

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

421     was loaded.
422     - NKSP built-in wait() script function: abort script execution if
423     a negative or zero wait time was passed as argument (since this is
424     a common indication of a bug either of the script or even of the
425     engine, which could lead to RT instability or even worse).
426 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
427     threatening scripts.
428 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.

443     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
444     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
445     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
446 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
447     of its possible parameter selections.
448     - Added built-in script function "set_event_par()" and implemented some
449     of its possible parameter selections.
450 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
451 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
452 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
453     built-in function "ignore_controller()".
454 schoenebeck 3214 - Implemented built-in script function "change_velo()".
455     - Implemented built-in script function "change_note()".
456 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
457     intuitive behavior if used in combination with "change_vol_time()" or
458     "change_tune_time()" respectively: now tuning/volume changes are only
459     assigned (without delay) immediately to a new note if the respective
460     timing function has not been called before, otherwise the volume/tuning
461     changes are automatically faded (before, only the event's time stamp was
462     relevant).
463 schoenebeck 3221 - Implemented built-in script function "array_equal()".
464     - Implemented built-in script function "search()".
465     - Implemented built-in script function "sort()".
466     - NKSP Fix: Never suspend "init" event handlers.
467 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
468     available for gig format engine).
469 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
470     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
471     - Implemented built-in script function "change_vol_curve()".
472     - Implemented built-in script function "change_tune_curve()".
473 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
474     offset with argument 3, where special value -1 means to use the regular
475     sample offset as defined by the instrument file.
476 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
477     - Built-in variable $EVENT_NOTE is now a read-only variable.
478     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
479     - built-in "play_note()" function now accepts -2 for its fourth argument
480     (note duration) which means the life time of the note shall be sticked
481     to the requested note number of argument 1.
482     - Fix: built-in "play_note()" function now returns 0 as result value if
483     -1 was passed for its fourth argument (note duration) and the respective
484     parent note is already gone.
485 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
486 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

493     another script handler by passing its callback ID.
494 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
495     "init" event handlers.
496 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
497     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
498     to retrieve all code blocks filtered out by the preprocessor.
499 schoenebeck 3293 - Added built-in script function "fork()".
500     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
501     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
502     - Fixed potential crash when accessing dynamic built-in array variables.
503 schoenebeck 3296 - Added built-in script function "callback_status()".
504     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
505     - Added built-in constant $CALLBACK_STATUS_QUEUE.
506     - Added built-in constant $CALLBACK_STATUS_RUNNING.
507 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
508     "change_decay()" and "change_release()" to i.e. allow passing 2000000
509     for doubling the respective time.
510 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
511     to a lexer start condition stack underrun.
512     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
513     USE_CODE_IF_NOT() preprocessor statements.
514 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
515     can be set to disable all subsequent built-in "message()" function calls
516     on preprocessor level.
517 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
518 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
519     to avoid the editor app to crash on ill-formed text input.
520 schoenebeck 3335 - Added built-in script function "change_pan_time()".
521     - Added built-in script function "change_pan_curve()".
522 schoenebeck 3360 - Added built-in script function "change_cutoff_attack()".
523     - Added built-in script function "change_cutoff_decay()".
524     - Added built-in script function "change_cutoff_sustain()".
525     - Added built-in script function "change_cutoff_release()".
526     - Added built-in script function "change_cutoff_lfo_depth()".
527     - Added built-in script function "change_cutoff_lfo_freq()".
528 schoenebeck 2871
529 schoenebeck 3050 * Instruments DB:
530     - Fixed memory access bug of general DB access code which lead to
531     undefined behavior.
532 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
533     - The instrument DB path of linuxsampler's --create-instruments-db argument
534     is now optional, if it is missing, then a default location is used.
535 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
536     - Added support for scanning Sound Font (.sf2) files.
537 schoenebeck 3101 - Fixed undefined DB transaction behavior.

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

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

685     - added v1 LFO opcodes to parser (no support in engine yet)
686 persson 2082 - added support for amp_veltrack and amp_velcurve_N
687     - fine-tuned the default velocity curve
688 persson 2086 - added support for transpose
689     - fixed crash when using sw_down/up
690     - improved logic for sw_lokey/hikey/up/down/last
691     - added more v1 aliases to parser
692 persson 2091 - reduced memory usage for sfz data
693 persson 2101 - RT-safeness: avoid malloc in audio thread
694     - fixed a bug that could cause voice stealing to fail
695 persson 2106 - optimized sample lookup
696 persson 2114 - improved support for exclusive groups (group, off_by and
697     off_mode)

699     - added support for loop_mode=one_shot
700 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs
701     - added support for Ogg Vorbis sample files
702 persson 2167 - use loop markers from sample file if loop_start and loop_end are
703     not set in sfz file
704 persson 2175 - implemeted filters. Filter types: lowpass, bandpass, bandreject
705     and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
706     cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
707     cutoff_cc, cutoff_chanaft.
708     - bugfix: zero ampeg_sustain didn't work
709 persson 2176 - added support for velocity effect on amplifier envelope time
710     (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
711     ampeg_vel2release)
712 persson 2203 - added support for EG hold (ampeg_hold)

1032 schoenebeck 2123 channel to a different engine type
1033 persson 2127 - fixed crash when deleting a sampler channel or changing engine
1034     type while an instrument load was in progress
1035 persson 2162 - bugfix: playing a note while changing the instrument could cause
1036     a crash, or give "Handing back unknown region" error messages
1037 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
1038     refresh) could cause instruments to be unloaded
1039 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
1040     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1041 persson 2185 - Mac OS X: fixed hanging threads
1042 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
1043     it caused hanging threads on Windows
1044 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
1045     after MIDI/audio device creation failure
1046 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1047     instruments were uselessly precached with zero samples, however it still
1048     took the full preloading time and on 1st program change the respective
1049     instrument was completely reloaded again.
1050 persson 2277 - fixed handling of rapid bank select and program change messages
1051     sent to the same sampler channel (patch from the Open Octave

1069     (labelled "Disk stream not available in time")
1070 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
1071     crashes and noise on such transitions).
1072 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1073     (fixes #208)
1074 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1075     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1076     practically irrelevant, however it caused problems with the new LSCP
1077     shell's auto completion feature).
1078 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1079     after each other (fixes #231).

1102 schoenebeck 1639
1103 schoenebeck 1601 * general changes:
1104     - bugfix: on some POSIX systems instrument editor plugins refused to
1105     load as we used a non-portable Linux specific struct field

1107 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
1108     plugin DLL on Windows systems failed
1109 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1110     - optimized the SynchronizedConfig class so it doesn't wait
1111     unnecessarily long after an update
1112 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
1113     events (e.g. to highlight the pressed keys on the virtual keyboard
1114     of gigedit)
1115 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
1116 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
1117 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1129 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
1130     be switched on by command line option "--stacktrace" (the automatic
1131     stacktrace mechanism seems to be broken on most systems at the moment)
1132 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1133     a pointer to the launched InstrumentEditor object
1134 schoenebeck 1876 - added optional 3rd party user data parameter for following
1135     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1136     InstrumentEditor::Launch(),

1157 iliev 1829 - added (experimental) CoreAudio driver
1158 persson 1888 - applied old fixes to the ASIO driver that were included in the
1159     previous binary release but accidentally never committed to CVS
1160     (fixes #117)
1161 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

1169     stereo
1170 persson 1922 - added channel routing, fxsends and midi maps to the settings
1171     stored in the plugin state
1172 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
1173     AudioChannel::CopyTo() methods using GCC vector exensions

1176     exception when getting parameters from a disconnected device
1177 schoenebeck 1599
1178 persson 1651 * MIDI driver:
1179     - added JACK MIDI driver
1180 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

1182     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1183 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1184 persson 1887 CoreMidi or AU
1185 persson 1889 - fixed mingw-w64 compilation error in MME driver
1186 persson 1924 - made program change handling in MIDI thread real-time safe by
1187     moving the logic to a non-RT thread
1188 persson 1951 - fixed minor memory leak in ALSA driver
1189 persson 1651
1190 schoenebeck 1604 * instruments database:
1191 iliev 1603 - avoid time consuming samples scanning when adding instruments
1192     to the instruments database
1193 iliev 1727 - added support for handling lost files in the instruments database
1194 iliev 1781 - Implemented option for adding instruments in separate directories
1195     in the instruments database

1197 persson 1908 - work-around for missing fnmatch function on Windows to make
1198     instrument database compilable
1199 schoenebeck 1930 - added instrument database support on Windows
1200     works with both standalone mode and VST plugin.
1201     the instruments DB file is located in
1202     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1203     databases for each windows user
1204     if no DB is present it automatically creates the .linuxsampler subdir
1205     and then creates an empty DB
1206 persson 1943 - fixed recursive import, which was broken on Windows
1207 iliev 1603
1208 persson 1644 * Gigasampler format engine:
1209     - fixed a memory leak that could happen when a channel was deleted
1210     while notes were playing
1211 persson 1646 - made it possible to load an instrument even if the audio thread
1212     isn't running
1213 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1214     enough for piano gigs with pedal noise samples
1215 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1216     respective FX send MIDI controller was used
1217 schoenebeck 1724 - added support for GM global device volume SysEx message
1218 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1219     whole sampler [default] or only to the sampler channels that are
1220     connected to the respective MIDI input port the SysEx message arrived
1221     on)
1222 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1223     sometimes wrongly killed in the same buffer, causing no sound to
1224     be played
1225 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1226     which is usally used to switch a part between chromatic sounds and
1227     drumkit sounds (as opposed to their common default setting of MIDI
1228     part 10 being a drumkit part and all other ones chromatic parts), in
1229     LS however one can switch between the first 16 MIDI instrument maps
1230     defined for the sampler
1231 persson 1764 - made it possible to create multiple sample channels even if the
1232     audio thread isn't running
1233 persson 1844 - fixed crash when removing channel with active voices (#116)
1234 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1235     un-cache the respective sample if it's really not used by any
1236     sampler engine anymore
1237     - re-cache samples in case they were changed by an instrument editor,
1238     e.g. when a sample was added while playing (#82)
1239 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1240     same time stamp as the voice's note-on event and occured both in the
1241     same audio fragment cycle (fixes bug #112)
1242 persson 1858 - added support for the "fine tune" and "pitch bend range"
1243     instrument-level gig parameters
1244     - fixed minor artifacts in pitch bend handling
1245 schoenebeck 1860 - added support for GS Reset SysEx message
1246 persson 1862 - allow gig files to use unlimited downward pitch shifting
1247     - added a limit check for upward pitch shifting
1248 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1249     note was silent
1250 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1251     same time a new instrument was loading
1252 persson 1644
1253 schoenebeck 1687 * LSCP server:
1254     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1255     react on MIDI data arriving on certain sampler channels (so far only
1256     Note-On and Note-Off events are sent via this LSCP event)
1257 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1258     react on MIDI data arriving on certain MIDI input devices (so far only
1259     Note-On and Note-Off events are sent via this LSCP event)
1260 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1261     SET DB_INSTRUMENT FILE_PATH
1262 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1263     frontends to send MIDI messages to specific sampler channel
1264     - added two additional fields to GET FILE INSTRUMENT INFO command -
1265     KEY_BINDINGS and KEYSWITCH_BINDINGS
1266 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1267     was incorrect
1268 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1269 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1270     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1271     be triggered respectively
1272     - added new LSCP command "SET STREAMS" to globally alter the maximum
1273     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1274     which will be triggered respectively
1275 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1276     a gigedit file dialog is opened)
1277 iliev 1848 - close all connections when LSCPServer is deleted
1278 iliev 1882 - hard close of all sockets on exit
1279 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1280     driver
1281 schoenebeck 1687

1283     - fixed a crash which occurs when removing a sampler channel waiting
1284     to start instrument loading after another channel
1285 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1286     instrument loading in progress (bug #113)
1287 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1288     instrument with PERSISTENT load mode
1289 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1290     - fixed memory leaks when issuing the following LSCP commands:
1291     GET AUDIO_OUTPUT_DRIVER INFO
1292     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1293     GET MIDI_INPUT_DRIVER INFO
1294     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1295     - fixed possible compilation error when sqlite is not present
1296 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1297 iliev 1847 - fixed crash when changing the audio output device of a sampler
1298     channel with loaded instrument and start playing notes
1299 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1300 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1301     PowerPC, which probably could cause crashes on that platform
1302 persson 1889 - fixed a memory management error which could cause a crash when a
1303     plugin was unloaded
1304 persson 1896 - bugfix: two private structs had the same name, which could cause
1305     problems if the linker chose the wrong constructor
1306 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1307     Windows
1308 iliev 1761

1310 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1311 schoenebeck 1454
1312     * packaging changes:
1313     - added autoconf checks for pthread library
1314     - added autoconf check for pthread bug found on certain NPTL-enabled
1315     glibc versions (see Gentoo bug report #194076)
1316 senoner 1502 - added autoconf checks for MS Windows
1317 schoenebeck 1454
1318 persson 1455 * general changes:
1319     - bugfix: the thread used by an editor plugin didn't die when the
1320     editor closed
1321 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1322     out all the space. operator--() did not apply size_mask after
1323     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1324     order to avoid problems with the _NonVolatileReader functions.
1325     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1326     GetWriteSpace(). Since this function is currently only used in
1327     the stream's qsort() compare function, it didn't trigger any
1328     bugs.
1329     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1330     24bit mode too. Faster method to read 24bit words on little
1331     endian machines (x86): replaced 3 byte reads + shifts with a 1
1332     unaligned 32bit read and shift
1333     - experimental support for MS Windows (MIDI input via MME, AUDIO
1334     output via ASIO)
1335     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1336 iliev 1541 - support for monitoring the total number of active disk streams
1337     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1338     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1339 persson 1455
1340 senoner 1500 * AUDIO driver:
1341 persson 1534 - added Windows ASIO low latency audio driver
1342 senoner 1500
1343 senoner 1485 * MIDI driver:
1344 schoenebeck 1495 - added MME Windows MIDI driver
1345 senoner 1485
1346 schoenebeck 1471 * LSCP server:
1347     - added support for Windows style path / filenames, however with
1348     forward slash path separators instead of backslash
1349     (i.e. "C:/foo/bar.gig")
1350 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1351     apostrophes as well
1352 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1353     "LIST FILE INSTRUMENTS <file>" and
1354     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1355     about an arbitrary instrument file on the system where the sampler is
1356     running on
1357 schoenebeck 1471
1358 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1359 schoenebeck 947
1360 schoenebeck 1065 * packaging changes:
1361 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1362     API header files anymore
1363 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1364     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1365 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1366     capable to execute our autoconf environment, thus no need anymore
1367     to maintain the compile time configuration file (osx/version.h) for
1368     OSX manually (patch by Toshi Nagata)
1369 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1370     parameters
1371 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1372     C++ API header files, all implementation internal global definitions
1373     are now in global_private.h
1374     - atomic.h is not exposed to the C++ API anymore
1375     - no need to include config.h anymore for using LS's API header files
1376     - fixed warnings in API doc generation
1377 schoenebeck 1065
1378 schoenebeck 947 * general changes:
1379     - replaced the old, confusing MIDI program change mechanism by a
1380     flexible MIDI instrument mapper which allows to map arbitrary
1381 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1382 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1383     loaded on the respective channel when such MIDI program change
1384     messages arrive, beside that, each entry allows to define a life-time
1385     strategy for the instrument, so the user can define whether the
1386     instrument should i.e. be permanently loaded (to be able to switch
1387     quickly among sounds) or i.e. loaded just on demand when the
1388     respective program change arrives (to safe RAM space), as well as a
1389     global volume factor for each entry, so the user can adjust the volume
1390     dynamic of his mapped instrument collection without having to modify
1391 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1392     MIDI instrument maps and assign each sampler channel individually
1393     a certain map, so that i.e. separation of normal instruments and
1394     drumkits is possible
1395 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1396     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1397 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1398     due to a constant size RingBuffer FIFO which is now replaced by a
1399     dynamic (unlimited) size std::list FIFO
1400 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1401     output channels for being processed by external effect processors
1402     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1403     controllers
1404 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1405 iliev 1130 - Implemented new, improved notification system
1406 schoenebeck 1149 - fixed compilation errors regarding OSX
1407     (patch by Toshi Nagata)
1408 iliev 1161 - implemented instruments database
1409 iliev 1345 - added support for escape sequences to the instruments database
1410 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1411     within the sampler's process (by using instrument editor plugins),
1412     you'll notice the new "Registered instrument editors:" message on
1413 schoenebeck 1407 startup, added a new LSCP command:
1414     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1415 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1416     given sampler channel, the plugin path can be overridden at compile
1417     time with ./configure --enable-plugin-dir=/some/dir
1418 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1419     in the sampler's process to safely edit instruments while playing
1420     without a crash (hopefully) by either suspending single regions
1421     wherever possible or if unavoidable whole engine(s)
1422 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1423     policy and priority on thread level, set a minimum stack size for
1424     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1425     threads simply inherited properties of starting thread instead of
1426     setting their own policy and priority
1427 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1428     main process did not wait for the stack trace process to finish
1429     its output
1430 persson 1248 - fixed some minor memory leaks
1431 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1432     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1433 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1434     register, to avoid relocations in the text segment at runtime)
1435 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1436 schoenebeck 947
1437     * MIDI driver:
1438     - dispatch bank select (MSB and LSB) messages
1439    
1440 schoenebeck 1049 * audio driver:
1441     - the ALSA audio output driver parameters now reflect the correct
1442     parameter value ranges for the respective selected sound card
1443     (patch by Till Wimmer, a bit fixed and extended)
1444    
1445 persson 951 * Gigasampler format engine:
1446     - if a filter is used and EG2 finishes before EG1, let the voice
1447     die when EG2 has finished (this fixes a problem with clicks and
1448     voice starvation for some gigs)
1449 persson 1038 - playback is no longer disabled during instrument loading
1450     - all notes playing on a channel that changes its instrument keep
1451     playing with the old instrument until they get a note off
1452     command
1453 persson 1039 - EG fix: a release value of zero could cause noises or crash
1454 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1455 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1456     above max sustain level, which means that there is a decay phase
1457     even if sustain is 100%
1458 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1459     noises or crashes
1460 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1461 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1462     supplied to the configure script (fixes #46)
1463 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1464     instead of a fix value
1465 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1466     127 (solo mode) only kill voices if the respective mode really
1467     changed
1468 persson 951
1469 schoenebeck 1244 * LSCP server:
1470     - fixed compile time error for old Bison versions
1471     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1472 schoenebeck 1245 - parser now supports extended ASCII character set
1473     (up to ASCII code 255, i.e. includes now umlauts and accents)
1474     - filename arguments in LSCP commands now allow to use escape
1475     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1476     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1477     code value like \xf2) (fixes bug #24)
1478 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1479     least one of their text-based parameters (i.e. name, description):
1480     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1481     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1482     "SET DB_INSTRUMENT_DIRECTORY NAME",
1483     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1484     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1485     "FIND DB_INSTRUMENT_DIRECTORIES"
1486 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1487     occured, the unexpected character and the actually expected, possible
1488     character(s), the latter only if less than 5 possibilities)
1489 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1490     settings
1491 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1492     of strings were treated as being one string containing commas
1493     (fixes #57)
1494 schoenebeck 1244
1495 iliev 959 * Bug fixes:
1496     - fixed crash occurring on certain LSCP scripts (Bug 39)
1497 persson 1038 - another thread safety fix for lscp "load engine" and "set
1498     channel audio output device"
1499 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1500     on a sampler channel with connected MIDI device
1501 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1502     device connected to a sampler channel to number less then or equal
1503     to the index of the port to which the sampler channel is connected.
1504 iliev 1296 - The previous bindings were not been disconnected when altering
1505     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1506     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1507 iliev 1297 - The active stream/voice count statistic was incorrect.
1508 iliev 1298 - notification events were not been sent for some sampler
1509     channel changes
1510 iliev 1305 - added default min and max values to restrict the number of allowed
1511     audio output channels and MIDI input ports
1512 iliev 1306 - the connection to the PCM interface is now closed when destroying
1513     an audio output device
1514 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1515 iliev 959
1516 schoenebeck 1221 * test cases:
1517     - updated and fixed (haven't been touched in a while)
1518    
1519 schoenebeck 937 Version 0.4.0 (24 November 2006)
1520 persson 696
1521 schoenebeck 697 * packaging changes:
1522 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1523     to post-(un)install steps; added devel package for liblinuxsampler;
1524     to linuxsampler.spec (RPM)
1525 schoenebeck 697 - install necessary development header files for allowing 3rd party
1526     applications to link against liblinuxsampler
1527     - liblinuxsampler's API documentation can be generated with 'make docs'
1528     (Doxygen required)
1529 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1530     implementation (currently either an integer math solution or a
1531     di-harmonic approximation), automatic detection can be overriden
1532     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1533     configure script argument though (mandatory for cross-compilation)
1534 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1535     provided some on his own (as CXXFLAGS)
1536 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1537     messages
1538 schoenebeck 852 - added compile time options to allow disabling the various audio and
1539     MIDI drivers
1540 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1541     (patch by Ebrahim Mayat)
1542 schoenebeck 697
1543 persson 696 * Gigasampler format engine:
1544 schoenebeck 738 - extensive synthesis optimization
1545     (reimplementation of EGs and LFO(s), removed synthesis parameter
1546     prerendering and the synthesis parameter matrix in general, splitting
1547     each audio fragment into subfragments now where each subfragment uses
1548 persson 830 constant pitch and filter coefficients. The volume coefficient is
1549     linearly interpolated inside a subfragment, unless
1550     --disable-interpolate-volume is set.)
1551 persson 696 - fine tuning of the EG modulation parameters
1552 persson 729 - improved filter cutoff calculation by adding support for the
1553     following gig parameters: Cutoff freq (used when no cutoff
1554     controller is defined), Control invert, Minimum cutoff, Velocity
1555 persson 791 curve and Velocity range. The keyboard tracking now scales
1556     cutoff frequency instead of resonance.
1557 persson 877 - added support for gig parameter Resonance.
1558 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1559 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1560     which can be overridden with --enable-global-attenuation
1561 persson 783 - EG fixes: made the length of "attack hold" stage more
1562     accurate. Release stage can now start before attack stage
1563 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1564     time now has a minimal value to prevent clicks.
1565 persson 799 - fixed pitch changes larger than one octave
1566 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1567     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1568     all modes can be altered via standard GM messages, that is CC5 for
1569     altering portamento time, CC65 for enabling / disabling portamento
1570     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1571 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1572     parameter) and crossfade
1573 persson 831 - added support for the "attenuation controller threshold" gig
1574     parameter
1575 persson 832 - added smoothing of volume changes caused by control change
1576     messages
1577 persson 865 - sample loop parameters are now taken from the DimensionRegion
1578     instead of the wave chunk
1579     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1580     not equal to a power of two
1581 persson 877 - reimplementation of the filter algorithm. The new filter is more
1582     accurate and supports all gig filter types, including bandreject
1583     and lowpass turbo.
1584 persson 903 - real support for 24 bit samples - samples are not truncated to
1585     16 bits anymore
1586     - support for aftertouch (channel pressure, not polyphonic
1587     aftertouch)
1588 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1589     amplifying from 0)
1590 persson 696
1591 schoenebeck 711 * LSCP server:
1592     - fixed application exit on broken pipe error (fixes bug #20)
1593 iliev 793 - fixed the notification messages delay due to lack of
1594     network activity (fixes bug #26)
1595 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1596     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1597 schoenebeck 711
1598 schoenebeck 838 * audio driver:
1599     - added aRts audio output driver (by no means RT safe)
1600    
1601 schoenebeck 775 * MIDI driver:
1602     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1603     messages several times instead of once
1604 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1605     for events (i.e. for offline rendering based MIDI drivers)
1606 persson 922 - added checks for bad MIDI data
1607 schoenebeck 775
1608 schoenebeck 900 * linuxsampler application:
1609     - show available sampler engine types on startup
1610    
1611 schoenebeck 705 * general changes:
1612     - support for muting sampler channels and solo mode of the same, two new
1613     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1614     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1615     introduced for this, the behavior is the same like on a mixer console
1616 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1617     --enable-process-muted-channels which can be used to enable the
1618     processing of muted channels.
1619 iliev 777 - support for sostenuto pedal
1620 iliev 779 - support for monitoring the total number of active voices
1621 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1622     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1623 persson 835 - fixed some memory management errors
1624 persson 841 - fixed some concurrency problems that could lead to crashes when
1625     LSCP commands were executed
1626 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1627     sampler channel (fixes bug #36)
1628 schoenebeck 705
1629 schoenebeck 692 Version 0.3.3 (15 July 2005)
1630 schoenebeck 686
1631     * packaging changes:
1632     - fixed compilation with gcc 4.0
1633    
1634 schoenebeck 687 * Gigasampler format engine:
1635     - LFO preprocessing was performed even though the respective LFO was
1636     disabled by the instrument patch (minor efficiency fix)
1637 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1638     for volume ramp downs in the same fragment (needed for current voice
1639     stealing implementation) then simply inform the user with a warning
1640     about possible click sounds and reduce the volume ramp down
1641     appropriately instead of cancelling the audio device connection
1642 schoenebeck 687
1643 schoenebeck 677 Version 0.3.2 (24 June 2005)
1644 schoenebeck 609
1645     * packaging changes:
1646     - updated autotools build files to compile on OS X
1647     (conditional compilation of CoreMIDI and MidiShare drivers)
1648 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1649     './configure --disable-asm' (definitely not recommended)
1650 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1651     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1652     (due to 'dist-bzip2' automake option)
1653 schoenebeck 649
1654     * Gigasampler format engine:
1655     - support for the gig parameters for "release velocity response" curves
1656     - fine tuning of the EGADSR envelope
1657     - volume of release triggered samples now depends on note-on velocity,
1658     note length and gig parameter "release trigger decay" instead of
1659     note-off velocity.
1660 schoenebeck 663 - revised voice stealing
1661     (fixes crash and endless loop caused by voice stealing)
1662 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1663 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1664     instead of when the respective voice is actually launched
1665     (fixes undefined behavior if stolen voices belonged to a key group -
1666     this case was followed by a "killed voice survived" error message)
1667 schoenebeck 669 - fixed minor issue with null/silence samples
1668     (those stole voices even though they don't need a voice at all which
1669     resulted in "voice stealing didn't work out" messages)
1670 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1671     instrument or audio output device change
1672 schoenebeck 654
1673 schoenebeck 620 * LSCP server:
1674 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1675 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1676 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1677 schoenebeck 609
1678 schoenebeck 668 * linuxsampler application:
1679     - added command line parameters --lscp-addr and --lscp-port to override
1680     default IP address and port of LSCP server
1681    
1682 schoenebeck 579 Version 0.3.1 (24 May 2005)
1683    
1684     * initial release
