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 3550
14 schoenebeck 3551 * Real-time instrument scripts:
15     - Added method ScriptVM::setExitResultEnabled() which allows to
16     explicitly enable the built-in exit() function to optionally accept
17     one function argument; the value of the passed exit() function
18     argument will then become available by calling
19     VMExecContext::exitResult() after script execution.
20 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
21 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
22     with a regular character (a-z or A-Z); starting them with a digit or
23     underscore is not allowed.
24     - NKSP parser fix: equal comparison operator "=" and not equal comparison
25     operator "#" must only accept integer operands.
26     - NKSP language: Implemented support for standard units like Hertz, seconds,
27     Bel including support for metric unit prefixes; so one can now e.g.
28     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
29     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
30     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
31     - NKSP language: Introduced "final" operator "!" which is specifically
32     intended for synthesis parameter values to denote that the synthesis
33     parameter value is intended to be the "final" value for that synthesis
34     parameter that should explicitly be used by the engine and thus causing
35     the sampler engine to ignore all other modulation sources for the same
36     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
37     variable or formula with this new "!" operator the expression is marked as
38     being "final".
39 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
40     and their potential metric prefix token.
41 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
42     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
43     - NKSP language: Added support for NKSP real number (floating point) script
44     variables (declare ~foo).
45     - NKSP language: Added support for NKSP real number (floating point) array
46     script variables (declare ?foo[]).
47     - Built-in script function "message()" accepts now real number argument as
48     well.
49     - Added built-in script function "real_to_int()" and its short hand form
50     "int()" for casting from real number to integer in NKSP scripts.
51     - Added built-in script function "int_to_real()" and its short hand form
52     "real()" for casting from integer to real number in NKSP scripts.
53 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
54     argument as well.
55 schoenebeck 3577 - Built-in script functions may have a different return type depending on
56     the arguments passed to the function.
57     - Built-in script function "abs()" optionally accepts and returns real
58     number.
59     - Built-in script functions "min()" and "max()" optionally accept real
60     number arguments and return real number as result in that case.
61 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
62     built-in functions (added methods VMFunction::returnUnitType() and
63     VMFunction::returnsFinal() for that purpose which must be implemented by
64     built-in function implementations).
65     - NKSP language: Allow metric unit prefixes of numeric scalar and array
66     variables to be changed freely at runtime (unlike unit types like Hz etc.
67     which are still sticky, parse-time features of variables which cannot be
68     changed at runtime for the intentional sake of determinism).
69     - NKSP language: 'final' values are prohibited for array variables for now
70     (attempt causes a parsers error).
71     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
72     conditions of runtime control structures like if(), while(), select()
73     (attempt causes a parser error).
74     - NKSP VM API: Allow built-in functions to perform their own, individual
75     parse time checks of arguments going to be passed to the function at
76     runtime (added method VMFunction::checkArgs() for that purpose).
77     - NKSP language: raise parser warning if only one operand of binary
78     operators (like logical 'or' comparison) contain a 'final' value (because
79     it would always yield in a 'final' result in such cases).
80     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
81     different metric unit prefixes, which will behave as expected (e.g.
82     result of expression '1000us < 2ms' is true).
83     - NKSP language: Allow adding values with different metric unit prefixes
84     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
85     - NKSP language: Allow subtracting values with different metric unit
86     prefixes (e.g. result of expression '1ms - 20us' is '980us').
87     - NKSP language: Allow multiplying with any metric unit prefixes
88     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
89     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
90     we don't have any considerable practical use for a term like '4s^2'
91     (hence any attempt multiplying two unit types still causes parser error).
92     - NKSP language: Allow dividing by any metric unit prefixes and allow
93     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
94     yields in unit free result '8'). So this is now a way to cast units away
95     e.g. for passing the result to other expressions, certain function calls
96     or variables which are not accepting any units (or that specific unit).
97     - NKSP language: integer arrays and real number arrays can now be converted
98     to strings (e.g. for dumping their content with message() calls for
99     script debugging purposes).
100     - NKSP language: expressions and variables with units are now correctly
101     casted to strings (e.g. with message() calls).
102     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
103     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
104     floating point tolerances into account.
105     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
106     VMScalarNumberExpr::evalCastReal().
107     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
108     'VMIntArrayExpr' and 'VMRealArrayExpr'.
109     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
110     unitFactor() (runtime) methods.
111     - Built-in function "exit()" supports now returning units and 'final'ness
112     for test cases.
113     - The following built-in functions support now units as well: "abs()",
114     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
115     "real_to_int()", "int()", "int_to_real()" and "real()".
116     - Built-in functions "array_equal()", "search()" and "sort()" support now
117     real number arrays (correctly) as well.
118     - Added individual parse time checks of arguments to be passed to built-in
119     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
120     "array_equal()" and "search()" specific for their individual purposes.
121 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
122     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
123     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
124     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
125     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
126     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
127     isScalarNumber() -> isNumber()).
128 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
129     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
130     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
131     as convenient methods for automatically converting values to expected
132     metric value basis.
133     - Built-in function "wait()" accepts now both integers and real numbers as
134     argument.
135 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
136     VMFunction::argType(vmint iArg) which was already superseded by its new
137     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
138     - NKSP parser: if wrong argument type was passed to a built-in function and
139     that built-in function accepts more than one data type for the argument,
140     then show all supported data types as parser error message.
141 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
142     unit type as well for its 3rd and 4th function arguments.
143     - The following built-in functions accept now real numbers as well for their
144     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
145     "change_attack()", "change_decay()", "change_release()",
146     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
147     "change_cutoff_sustain()", "change_cutoff_release()",
148     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
149     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
150     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
151     - Fixed built-in function "change_play_pos()" not having accepted metric
152     prefixes at all.
153 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
154     with unit type (for their 2nd argument) as if they were relative values
155     (that is as if they were passed without a unit type): "change_attack()",
156     "change_decay()", "change_release()", "change_cutoff_attack()",
157     "change_cutoff_decay()", "change_cutoff_release()".
158     - Fixed the following built-in functions having applied completely wrong
159     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
160     respective EGs being their modulation sink assume uint data type with
161     value range 0..1000 instead of 0.0..1.0.
162     - Added individual parse-time checks of function arguments for the following
163     built-in functions: "play_note()", "note_off()", "set_event_mark()",
164     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
165     "change_decay()", "change_release()", "change_cutoff_attack()",
166     "change_cutoff_decay()", "change_cutoff_release()",
167     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
168     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
169     "change_pan_time()".
170     - Don't abort function call if unit type was used and at the same time
171     'final' operator was omitted for the primary value argument of the
172     following built-in functions: "change_cutoff()", "change_attack()",
173     "change_decay()", "change_release()", "change_cutoff_attack()",
174     "change_cutoff_decay()", "change_cutoff_release()",
175     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
176     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
177     "change_pan_time()", instead imply 'final'ness at runtime and raise an
178     appropriate parser warning at parse time.
179 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
180     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
181     "cos()", "tan()", "asin()", "acos()", "atan()".
182     - Added built-in script real number constant "~NI_MATH_PI".
183     - Added built-in script real number constant "~NI_MATH_E".
184 schoenebeck 3551
185 schoenebeck 3550 * test cases:
186 schoenebeck 3548 - Fixed compiler errors in test cases.
187     - Updated README for how to compile & run test cases.
188     - Updated test case
189     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
190     expected behaviour of the Mutex class implementation (recursive
191     mutex type).
192 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
193     functions.
194 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
195 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
196     int_to_real(), real(), real_to_int() and int(), as well as for the
197     plus, minus and negate language operators.
198 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
199     'final' operator usage cases.
200     - Added NKSP test cases for (floating point tolerance aware) real number
201     equalness / unequalness comparison.
202 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
203     initialization of arrays.
204 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
205     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
206     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
207 schoenebeck 3548
208 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
209 schoenebeck 3381
210     * Real-time instrument scripts:
211     - Fixed behavior of built-in NKSP functions change_sustain(),
212     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
213     and change_cutoff_release().
214    
215 schoenebeck 3444 * general changes:
216     - Only play release trigger samples on sustain pedal up if this behaviour
217     was explicitly requested by the instrument (otherwise only on note-off).
218 persson 3455 - Fixed compiler warnings.
219     - Fixed compilation error when cross-compiling to Mac.
220 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
221     (see bug #169).
222     - LSCP doc: Be more clear describing the two distinct approaches
223     of using external vs. internal effects (see bug #169).
224 schoenebeck 3514 - "optional" class: Fixed comparison operators.
225 schoenebeck 3444
226 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
227     - Format extension: If requested by instrument then don't play release
228     trigger sample on note-off events.
229    
230 schoenebeck 3487 * SFZ format engine:
231     - Fixed memory leak when releasing samples
232     (fixes bug #307, patch by Jacek Roszkowski)
233 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
234     (fixes bug #308, patch by Jacek Roszkowski).
235 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
236     (fixes bug #310, patch by Jacek Roszkowski).
237 schoenebeck 3487
238 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
239 persson 2837
240 persson 2856 * SFZ format engine:
241     - added support for <global>, <master> and #define (patch by Alby M)
242 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
243     - Added support for sfz extension opcode 'script' which may be used to
244     load real-time instrument script file (NKSP script language).
245 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
246 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
247 persson 3291 - sfz parser: allow missing space between header and opcode
248 persson 2856
249 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
250 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
251     cutoff settings.
252 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
253     all if an up-pitch of more than 40 semi tones was requested (I don't
254     think there is any stock gig sound that requires this behavior to
255     resemble its original sound).
256 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
257     be aborted (as LinuxSampler extension to the original GigaStudio 4
258     format).
259 schoenebeck 3072
260 persson 2837 * general changes:
261     - fixed printf type errors (mostly in debug messages)
262 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
263 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
264     allowing to sort data efficiently in real-time safe manner.
265     - RTList class: added methods for moving/inserting elements to arbitrary
266     position within a list.
267     - RTList class: added method fromPtr() for creating an Iterator object from
268     a raw element pointer.
269     - Attempt to partly fix resetting engine channels vs. resetting engine, an
270     overall cleanup of the Reset*(), ConnectAudioDevice(),
271     DisconnectAudioDevice() API methods would still be desirable though,
272     because the current situation is still inconsistent and error prone.
273 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
274     being directly assigned to a keyboard key. This allows more fine graded
275     processing of voices, which is i.e. required for certain instrument
276     script features.
277 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
278     (CC #64) events.
279     - Fix: Release trigger voices can now also distinguish correctly between
280     note-off and sustain pedal up events.
281 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
282     (while slow rate of crossfade smoother is preserved) to allow quick
283     volume and pan changes by instrument scripts for instance.
284 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
285     properly and thus were ignored for certain uses.
286 schoenebeck 3018 - Added new C++ API method
287     VirtualMidiDevice::SendChannelPressureToSampler().
288 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
289     sub threads is 16-byte aligned
290 schoenebeck 3054 - fixed numerous compiler warnings
291 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
292 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
293     fixes potential undefined behavior.
294 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
295     have a valid sample mapped (fixes bug #252).
296     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
297 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
298     subsequent optional argument due to glibc's implementation oddity
299     which expects a "=" sign, but no space between them.
300 persson 2837
301 schoenebeck 2866 * packaging changes:
302     - removed unnecessary dependency to libuuid
303     (originated by libgig's usage of it)
304 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
305     auto detect whether it (sh/c)ould output its messages in color.
306 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
307     substitution variable.
308     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
309 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
310     linuxsampler with instruments DB support.
311 schoenebeck 2866
312 schoenebeck 2871 * Real-time instrument scripts:
313     - Implemented scheduler for delayed MIDI events and for suspended scripts.
314     - Built-in script function "wait()": implemented support for function's
315     "duration-us" argument, thus scripts using this function are now
316     correctly resumed after the requested amount of microseconds.
317     - Built-in script function "play_note()": implemented support for
318     function's "duration-us" argument, thus notes triggered with this
319     argument are now correctly released after the requested amount of
320     microseconds.
321     - Fix: script events were not cleared when engine channel was reset,
322     potentially causing undefined behavior.
323     - Fixed crash which happened when trying to reference an undeclared
324     variable.
325 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
326     special value -1 for "duration-us" argument, which will cause the
327     triggered note to be released once the original note was released.
328 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
329     - Added new API method ScriptVM::syntaxHighlighting() which provides
330     a convenient syntax highlighting backend for external instrument
331     script editor applications.
332 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
333     - Extended parser issues to provide not only first line and first
334     column, but also last line and last column of issue (thus marking
335     the precise span of the issue within the source code).
336 schoenebeck 2902 - Reload script automatically after being modified by an instrument
337     editor.
338 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
339     like "on note end on".
340 schoenebeck 2931 - Implemented built-in script function "change_vol()".
341     - Implemented built-in script function "change_tune()".
342     - Implemented built-in script function "change_pan()".
343 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
344     - Implemented built-in script function "change_reso()".
345     - Implemented built-in script function "event_status()".
346     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
347     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
348     "event_status()" function.
349     - NKSP language: Added support for bitwise operators ".or.", ".and."
350     and ".not.".
351     - NKSP language scanner: Fixed IDs matching to require at least one
352     character (i.e. when matching function names or variable names).
353     - NKSP language scanner: disabled unusued rules.
354 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
355     be distinguished engine internally from "real" MIDI note on/off
356     events in order to avoid misbehaviors like hanging notes.

364     - NKSP language fix: string concatenation operator was right
365     associative instead of left (to right).
366 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
367     (i.e. "if end if").
368 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
369     - Implemented built-in script variable "$NI_CALLBACK_ID".
370     - Implemented built-in script variable "$NI_CALLBACK_TYPE".

382 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
383     synthesis parameter changes immediately in case the respective note
384     was triggered at the same time, instead of scheduling the parameter
385     change, especially because it would cause some parameter types's
386     changes either to be ramped (i.e. change_vol()) or other types even
387     to have not effect at all (i.e. change_attack()).
388 schoenebeck 2965 - Implemented built-in script function "sh_left()".

393     was loaded.
394     - NKSP built-in wait() script function: abort script execution if
395     a negative or zero wait time was passed as argument (since this is
396     a common indication of a bug either of the script or even of the
397     engine, which could lead to RT instability or even worse).
398 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
399     threatening scripts.
400 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.

415     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
416     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
417     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
418 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
419     of its possible parameter selections.
420     - Added built-in script function "set_event_par()" and implemented some
421     of its possible parameter selections.
422 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
423 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
424 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
425     built-in function "ignore_controller()".
426 schoenebeck 3214 - Implemented built-in script function "change_velo()".
427     - Implemented built-in script function "change_note()".
428 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
429     intuitive behavior if used in combination with "change_vol_time()" or
430     "change_tune_time()" respectively: now tuning/volume changes are only
431     assigned (without delay) immediately to a new note if the respective
432     timing function has not been called before, otherwise the volume/tuning
433     changes are automatically faded (before, only the event's time stamp was
434     relevant).
435 schoenebeck 3221 - Implemented built-in script function "array_equal()".
436     - Implemented built-in script function "search()".
437     - Implemented built-in script function "sort()".

439 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
440     available for gig format engine).
441 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
442     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
443     - Implemented built-in script function "change_vol_curve()".
444     - Implemented built-in script function "change_tune_curve()".
445 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
446     offset with argument 3, where special value -1 means to use the regular
447     sample offset as defined by the instrument file.
448 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
449     - Built-in variable $EVENT_NOTE is now a read-only variable.
450     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
451     - built-in "play_note()" function now accepts -2 for its fourth argument
452     (note duration) which means the life time of the note shall be sticked
453     to the requested note number of argument 1.
454     - Fix: built-in "play_note()" function now returns 0 as result value if
455     -1 was passed for its fourth argument (note duration) and the respective
456     parent note is already gone.
457 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
458 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

467     "init" event handlers.
468 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
469     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
470     to retrieve all code blocks filtered out by the preprocessor.
471 schoenebeck 3293 - Added built-in script function "fork()".
472     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
473     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
474     - Fixed potential crash when accessing dynamic built-in array variables.
475 schoenebeck 3296 - Added built-in script function "callback_status()".
476     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
477     - Added built-in constant $CALLBACK_STATUS_QUEUE.
478     - Added built-in constant $CALLBACK_STATUS_RUNNING.
479 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
480     "change_decay()" and "change_release()" to i.e. allow passing 2000000
481     for doubling the respective time.
482 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
483     to a lexer start condition stack underrun.
484     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
485     USE_CODE_IF_NOT() preprocessor statements.
486 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
487     can be set to disable all subsequent built-in "message()" function calls
488     on preprocessor level.
489 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
490 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
491     to avoid the editor app to crash on ill-formed text input.
492 schoenebeck 3335 - Added built-in script function "change_pan_time()".
493     - Added built-in script function "change_pan_curve()".

495     - Added built-in script function "change_cutoff_decay()".
496     - Added built-in script function "change_cutoff_sustain()".
497     - Added built-in script function "change_cutoff_release()".
498     - Added built-in script function "change_cutoff_lfo_depth()".
499     - Added built-in script function "change_cutoff_lfo_freq()".
500 schoenebeck 2871
501 schoenebeck 3050 * Instruments DB:
502     - Fixed memory access bug of general DB access code which lead to
503     undefined behavior.
504 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
505     - The instrument DB path of linuxsampler's --create-instruments-db argument
506     is now optional, if it is missing, then a default location is used.
507 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
508     - Added support for scanning Sound Font (.sf2) files.
509 schoenebeck 3101 - Fixed undefined DB transaction behavior.

520 persson 2185 - fixed compilation with gcc 4.6.1
521 persson 2203 - another "make dist" fix, for the LV2 plugin
522 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
523 persson 2197 - minor Makefile fix for building lscpparser when build and source
524     directories are separate
525 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
526     configure

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

659     - fine-tuned the default velocity curve
660 persson 2086 - added support for transpose
661     - fixed crash when using sw_down/up
662     - improved logic for sw_lokey/hikey/up/down/last
663     - added more v1 aliases to parser
664 persson 2091 - reduced memory usage for sfz data
665 persson 2101 - RT-safeness: avoid malloc in audio thread

1044 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1045     (fixes #208)
1046 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1047     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1048     practically irrelevant, however it caused problems with the new LSCP
1049     shell's auto completion feature).
1050 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1051     after each other (fixes #231).

1075 schoenebeck 1601 * general changes:
1076     - bugfix: on some POSIX systems instrument editor plugins refused to
1077     load as we used a non-portable Linux specific struct field

1079 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
1080     plugin DLL on Windows systems failed
1081 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1082     - optimized the SynchronizedConfig class so it doesn't wait
1083     unnecessarily long after an update
1084 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
1085     events (e.g. to highlight the pressed keys on the virtual keyboard
1086     of gigedit)
1087 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
1088 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
1089 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1101 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
1102     be switched on by command line option "--stacktrace" (the automatic
1103     stacktrace mechanism seems to be broken on most systems at the moment)
1104 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1105     a pointer to the launched InstrumentEditor object
1106 schoenebeck 1876 - added optional 3rd party user data parameter for following
1107     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1108     InstrumentEditor::Launch(),
1109     InstrumentManager::LaunchInstrumentEditor()
1110 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory

1119     - removed the nonsense audio channel constraint (which was hard coded to
1120     max. 100 audio channels) for most audio drivers
1121 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1122     opposed to the LSCP specs

1124     reflected the wrong value
1125 persson 1644 - fixed a memory management bug in ASIO driver
1126 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

1128 persson 1748 jack_client_new
1129 iliev 1829 - added (experimental) CoreAudio driver
1130 persson 1888 - applied old fixes to the ASIO driver that were included in the
1131     previous binary release but accidentally never committed to CVS
1132     (fixes #117)
1133 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1134     win64)
1135 persson 1895 - VST: added support for sample rate and buffer size changes

1141     stereo
1142 persson 1922 - added channel routing, fxsends and midi maps to the settings
1143     stored in the plugin state
1144 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
1145     AudioChannel::CopyTo() methods using GCC vector exensions

1148     exception when getting parameters from a disconnected device
1149 schoenebeck 1599
1150 persson 1651 * MIDI driver:
1151     - added JACK MIDI driver
1152 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
1153     want to (mis)use it for some purpose ("fixed" in all current MIDI
1154     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1155 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1156 persson 1887 CoreMidi or AU
1157 persson 1889 - fixed mingw-w64 compilation error in MME driver
1158 persson 1924 - made program change handling in MIDI thread real-time safe by
1159     moving the logic to a non-RT thread
1160 persson 1951 - fixed minor memory leak in ALSA driver
1161 persson 1651
1162 schoenebeck 1604 * instruments database:
1163 iliev 1603 - avoid time consuming samples scanning when adding instruments
1164     to the instruments database
1165 iliev 1727 - added support for handling lost files in the instruments database
1166 iliev 1781 - Implemented option for adding instruments in separate directories
1167     in the instruments database
1168     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1169 persson 1908 - work-around for missing fnmatch function on Windows to make
1170     instrument database compilable
1171 schoenebeck 1930 - added instrument database support on Windows
1172     works with both standalone mode and VST plugin.
1173     the instruments DB file is located in
1174     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1175     databases for each windows user
1176     if no DB is present it automatically creates the .linuxsampler subdir
1177     and then creates an empty DB
1178 persson 1943 - fixed recursive import, which was broken on Windows
1179 iliev 1603
1180 persson 1644 * Gigasampler format engine:
1181     - fixed a memory leak that could happen when a channel was deleted
1182     while notes were playing
1183 persson 1646 - made it possible to load an instrument even if the audio thread
1184     isn't running
1185 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1186     enough for piano gigs with pedal noise samples
1187 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1188     respective FX send MIDI controller was used
1189 schoenebeck 1724 - added support for GM global device volume SysEx message
1190 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1191     whole sampler [default] or only to the sampler channels that are
1192     connected to the respective MIDI input port the SysEx message arrived
1193     on)
1194 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1195     sometimes wrongly killed in the same buffer, causing no sound to
1196     be played
1197 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1198     which is usally used to switch a part between chromatic sounds and
1199     drumkit sounds (as opposed to their common default setting of MIDI
1200     part 10 being a drumkit part and all other ones chromatic parts), in
1201     LS however one can switch between the first 16 MIDI instrument maps
1202     defined for the sampler
1203 persson 1764 - made it possible to create multiple sample channels even if the
1204     audio thread isn't running
1205 persson 1844 - fixed crash when removing channel with active voices (#116)
1206 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1207     un-cache the respective sample if it's really not used by any
1208     sampler engine anymore
1209     - re-cache samples in case they were changed by an instrument editor,
1210     e.g. when a sample was added while playing (#82)
1211 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1212     same time stamp as the voice's note-on event and occured both in the
1213     same audio fragment cycle (fixes bug #112)
1214 persson 1858 - added support for the "fine tune" and "pitch bend range"
1215     instrument-level gig parameters
1216     - fixed minor artifacts in pitch bend handling
1217 schoenebeck 1860 - added support for GS Reset SysEx message
1218 persson 1862 - allow gig files to use unlimited downward pitch shifting
1219     - added a limit check for upward pitch shifting
1220 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1221     note was silent
1222 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1223     same time a new instrument was loading
1224 persson 1644
1225 schoenebeck 1687 * LSCP server:
1226     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1227     react on MIDI data arriving on certain sampler channels (so far only
1228     Note-On and Note-Off events are sent via this LSCP event)
1229 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1230     react on MIDI data arriving on certain MIDI input devices (so far only
1231     Note-On and Note-Off events are sent via this LSCP event)
1232 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1233     SET DB_INSTRUMENT FILE_PATH
1234 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1235     frontends to send MIDI messages to specific sampler channel
1236     - added two additional fields to GET FILE INSTRUMENT INFO command -
1237     KEY_BINDINGS and KEYSWITCH_BINDINGS
1238 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1239     was incorrect
1240 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1241 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1242     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1243     be triggered respectively
1244     - added new LSCP command "SET STREAMS" to globally alter the maximum
1245     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1246     which will be triggered respectively
1247 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1248     a gigedit file dialog is opened)
1249 iliev 1848 - close all connections when LSCPServer is deleted
1250 iliev 1882 - hard close of all sockets on exit
1251 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1252     driver
1253 schoenebeck 1687
1254 iliev 1761 * Bug fixes:
1255     - fixed a crash which occurs when removing a sampler channel waiting
1256     to start instrument loading after another channel
1257 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1258     instrument loading in progress (bug #113)
1259 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1260     instrument with PERSISTENT load mode
1261 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1262     - fixed memory leaks when issuing the following LSCP commands:
1263     GET AUDIO_OUTPUT_DRIVER INFO
1264     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1265     GET MIDI_INPUT_DRIVER INFO
1266     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1267     - fixed possible compilation error when sqlite is not present
1268 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1269 iliev 1847 - fixed crash when changing the audio output device of a sampler
1270     channel with loaded instrument and start playing notes
1271 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1272 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1273     PowerPC, which probably could cause crashes on that platform
1274 persson 1889 - fixed a memory management error which could cause a crash when a
1275     plugin was unloaded
1276 persson 1896 - bugfix: two private structs had the same name, which could cause
1277     problems if the linker chose the wrong constructor
1278 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1279     Windows
1280 iliev 1761
1281    
1282 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1283 schoenebeck 1454
1284     * packaging changes:
1285     - added autoconf checks for pthread library
1286     - added autoconf check for pthread bug found on certain NPTL-enabled
1287     glibc versions (see Gentoo bug report #194076)
1288 senoner 1502 - added autoconf checks for MS Windows
1289 schoenebeck 1454
1290 persson 1455 * general changes:
1291     - bugfix: the thread used by an editor plugin didn't die when the
1292     editor closed
1293 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1294     out all the space. operator--() did not apply size_mask after
1295     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1296     order to avoid problems with the _NonVolatileReader functions.
1297     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1298     GetWriteSpace(). Since this function is currently only used in
1299     the stream's qsort() compare function, it didn't trigger any
1300     bugs.
1301     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1302     24bit mode too. Faster method to read 24bit words on little
1303     endian machines (x86): replaced 3 byte reads + shifts with a 1
1304     unaligned 32bit read and shift
1305     - experimental support for MS Windows (MIDI input via MME, AUDIO
1306     output via ASIO)
1307     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1308 iliev 1541 - support for monitoring the total number of active disk streams
1309     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1310     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1311 persson 1455
1312 senoner 1500 * AUDIO driver:
1313 persson 1534 - added Windows ASIO low latency audio driver
1314 senoner 1500
1315 senoner 1485 * MIDI driver:
1316 schoenebeck 1495 - added MME Windows MIDI driver
1317 senoner 1485
1318 schoenebeck 1471 * LSCP server:
1319     - added support for Windows style path / filenames, however with
1320     forward slash path separators instead of backslash
1321     (i.e. "C:/foo/bar.gig")
1322 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1323     apostrophes as well
1324 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1325     "LIST FILE INSTRUMENTS <file>" and
1326     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1327     about an arbitrary instrument file on the system where the sampler is
1328     running on
1329 schoenebeck 1471
1330 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1331 schoenebeck 947
1332 schoenebeck 1065 * packaging changes:
1333 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1334     API header files anymore
1335 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1336     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1337 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1338     capable to execute our autoconf environment, thus no need anymore
1339     to maintain the compile time configuration file (osx/version.h) for
1340     OSX manually (patch by Toshi Nagata)
1341 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1342     parameters
1343 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1344     C++ API header files, all implementation internal global definitions
1345     are now in global_private.h
1346     - atomic.h is not exposed to the C++ API anymore
1347     - no need to include config.h anymore for using LS's API header files
1348     - fixed warnings in API doc generation
1349 schoenebeck 1065
1350 schoenebeck 947 * general changes:
1351     - replaced the old, confusing MIDI program change mechanism by a
1352     flexible MIDI instrument mapper which allows to map arbitrary
1353 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1354 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1355     loaded on the respective channel when such MIDI program change
1356     messages arrive, beside that, each entry allows to define a life-time
1357     strategy for the instrument, so the user can define whether the
1358     instrument should i.e. be permanently loaded (to be able to switch
1359     quickly among sounds) or i.e. loaded just on demand when the
1360     respective program change arrives (to safe RAM space), as well as a
1361     global volume factor for each entry, so the user can adjust the volume
1362     dynamic of his mapped instrument collection without having to modify
1363 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1364     MIDI instrument maps and assign each sampler channel individually
1365     a certain map, so that i.e. separation of normal instruments and
1366     drumkits is possible
1367 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1368     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1369 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1370     due to a constant size RingBuffer FIFO which is now replaced by a
1371     dynamic (unlimited) size std::list FIFO
1372 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1373     output channels for being processed by external effect processors
1374     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1375     controllers
1376 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1377 iliev 1130 - Implemented new, improved notification system
1378 schoenebeck 1149 - fixed compilation errors regarding OSX
1379     (patch by Toshi Nagata)
1380 iliev 1161 - implemented instruments database
1381 iliev 1345 - added support for escape sequences to the instruments database
1382 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1383     within the sampler's process (by using instrument editor plugins),
1384     you'll notice the new "Registered instrument editors:" message on
1385 schoenebeck 1407 startup, added a new LSCP command:
1386     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1387 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1388     given sampler channel, the plugin path can be overridden at compile
1389     time with ./configure --enable-plugin-dir=/some/dir
1390 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1391     in the sampler's process to safely edit instruments while playing
1392     without a crash (hopefully) by either suspending single regions
1393     wherever possible or if unavoidable whole engine(s)
1394 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1395     policy and priority on thread level, set a minimum stack size for
1396     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1397     threads simply inherited properties of starting thread instead of
1398     setting their own policy and priority
1399 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1400     main process did not wait for the stack trace process to finish
1401     its output
1402 persson 1248 - fixed some minor memory leaks
1403 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1404     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1405 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1406     register, to avoid relocations in the text segment at runtime)
1407 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1408 schoenebeck 947
1409     * MIDI driver:
1410     - dispatch bank select (MSB and LSB) messages
1411    
1412 schoenebeck 1049 * audio driver:
1413     - the ALSA audio output driver parameters now reflect the correct
1414     parameter value ranges for the respective selected sound card
1415     (patch by Till Wimmer, a bit fixed and extended)
1416    
1417 persson 951 * Gigasampler format engine:
1418     - if a filter is used and EG2 finishes before EG1, let the voice
1419     die when EG2 has finished (this fixes a problem with clicks and
1420     voice starvation for some gigs)
1421 persson 1038 - playback is no longer disabled during instrument loading
1422     - all notes playing on a channel that changes its instrument keep
1423     playing with the old instrument until they get a note off
1424     command
1425 persson 1039 - EG fix: a release value of zero could cause noises or crash
1426 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1427 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1428     above max sustain level, which means that there is a decay phase
1429     even if sustain is 100%
1430 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1431     noises or crashes
1432 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1433 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1434     supplied to the configure script (fixes #46)
1435 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1436     instead of a fix value
1437 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1438     127 (solo mode) only kill voices if the respective mode really
1439     changed
1440 persson 951
1441 schoenebeck 1244 * LSCP server:
1442     - fixed compile time error for old Bison versions
1443     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1444 schoenebeck 1245 - parser now supports extended ASCII character set
1445     (up to ASCII code 255, i.e. includes now umlauts and accents)
1446     - filename arguments in LSCP commands now allow to use escape
1447     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1448     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1449     code value like \xf2) (fixes bug #24)
1450 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1451     least one of their text-based parameters (i.e. name, description):
1452     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1453     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1454     "SET DB_INSTRUMENT_DIRECTORY NAME",
1455     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1456     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1457     "FIND DB_INSTRUMENT_DIRECTORIES"
1458 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1459     occured, the unexpected character and the actually expected, possible
1460     character(s), the latter only if less than 5 possibilities)
1461 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1462     settings
1463 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1464     of strings were treated as being one string containing commas
1465     (fixes #57)
1466 schoenebeck 1244
1467 iliev 959 * Bug fixes:
1468     - fixed crash occurring on certain LSCP scripts (Bug 39)
1469 persson 1038 - another thread safety fix for lscp "load engine" and "set
1470     channel audio output device"
1471 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1472     on a sampler channel with connected MIDI device
1473 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1474     device connected to a sampler channel to number less then or equal
1475     to the index of the port to which the sampler channel is connected.
1476 iliev 1296 - The previous bindings were not been disconnected when altering
1477     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1478     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1479 iliev 1297 - The active stream/voice count statistic was incorrect.
1480 iliev 1298 - notification events were not been sent for some sampler
1481     channel changes
1482 iliev 1305 - added default min and max values to restrict the number of allowed
1483     audio output channels and MIDI input ports
1484 iliev 1306 - the connection to the PCM interface is now closed when destroying
1485     an audio output device
1486 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1487 iliev 959
1488 schoenebeck 1221 * test cases:
1489     - updated and fixed (haven't been touched in a while)
1490    
1491 schoenebeck 937 Version 0.4.0 (24 November 2006)
1492 persson 696
1493 schoenebeck 697 * packaging changes:
1494 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1495     to post-(un)install steps; added devel package for liblinuxsampler;
1496     to linuxsampler.spec (RPM)
1497 schoenebeck 697 - install necessary development header files for allowing 3rd party
1498     applications to link against liblinuxsampler
1499     - liblinuxsampler's API documentation can be generated with 'make docs'
1500     (Doxygen required)
1501 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1502     implementation (currently either an integer math solution or a
1503     di-harmonic approximation), automatic detection can be overriden
1504     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1505     configure script argument though (mandatory for cross-compilation)
1506 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1507     provided some on his own (as CXXFLAGS)
1508 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1509     messages
1510 schoenebeck 852 - added compile time options to allow disabling the various audio and
1511     MIDI drivers
1512 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1513     (patch by Ebrahim Mayat)
1514 schoenebeck 697
1515 persson 696 * Gigasampler format engine:
1516 schoenebeck 738 - extensive synthesis optimization
1517     (reimplementation of EGs and LFO(s), removed synthesis parameter
1518     prerendering and the synthesis parameter matrix in general, splitting
1519     each audio fragment into subfragments now where each subfragment uses
1520 persson 830 constant pitch and filter coefficients. The volume coefficient is
1521     linearly interpolated inside a subfragment, unless
1522     --disable-interpolate-volume is set.)
1523 persson 696 - fine tuning of the EG modulation parameters
1524 persson 729 - improved filter cutoff calculation by adding support for the
1525     following gig parameters: Cutoff freq (used when no cutoff
1526     controller is defined), Control invert, Minimum cutoff, Velocity
1527 persson 791 curve and Velocity range. The keyboard tracking now scales
1528     cutoff frequency instead of resonance.
1529 persson 877 - added support for gig parameter Resonance.
1530 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1531 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1532     which can be overridden with --enable-global-attenuation
1533 persson 783 - EG fixes: made the length of "attack hold" stage more
1534     accurate. Release stage can now start before attack stage
1535 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1536     time now has a minimal value to prevent clicks.
1537 persson 799 - fixed pitch changes larger than one octave
1538 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1539     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1540     all modes can be altered via standard GM messages, that is CC5 for
1541     altering portamento time, CC65 for enabling / disabling portamento
1542     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1543 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1544     parameter) and crossfade
1545 persson 831 - added support for the "attenuation controller threshold" gig
1546     parameter
1547 persson 832 - added smoothing of volume changes caused by control change
1548     messages
1549 persson 865 - sample loop parameters are now taken from the DimensionRegion
1550     instead of the wave chunk
1551     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1552     not equal to a power of two
1553 persson 877 - reimplementation of the filter algorithm. The new filter is more
1554     accurate and supports all gig filter types, including bandreject
1555     and lowpass turbo.
1556 persson 903 - real support for 24 bit samples - samples are not truncated to
1557     16 bits anymore
1558     - support for aftertouch (channel pressure, not polyphonic
1559     aftertouch)
1560 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1561     amplifying from 0)
1562 persson 696
1563 schoenebeck 711 * LSCP server:
1564     - fixed application exit on broken pipe error (fixes bug #20)
1565 iliev 793 - fixed the notification messages delay due to lack of
1566     network activity (fixes bug #26)
1567 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1568     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1569 schoenebeck 711
1570 schoenebeck 838 * audio driver:
1571     - added aRts audio output driver (by no means RT safe)
1572    
1573 schoenebeck 775 * MIDI driver:
1574     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1575     messages several times instead of once
1576 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1577     for events (i.e. for offline rendering based MIDI drivers)
1578 persson 922 - added checks for bad MIDI data
1579 schoenebeck 775
1580 schoenebeck 900 * linuxsampler application:
1581     - show available sampler engine types on startup
1582    
1583 schoenebeck 705 * general changes:
1584     - support for muting sampler channels and solo mode of the same, two new
1585     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1586     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1587     introduced for this, the behavior is the same like on a mixer console
1588 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1589     --enable-process-muted-channels which can be used to enable the
1590     processing of muted channels.
1591 iliev 777 - support for sostenuto pedal
1592 iliev 779 - support for monitoring the total number of active voices
1593 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1594     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1595 persson 835 - fixed some memory management errors
1596 persson 841 - fixed some concurrency problems that could lead to crashes when
1597     LSCP commands were executed
1598 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1599     sampler channel (fixes bug #36)
1600 schoenebeck 705
1601 schoenebeck 692 Version 0.3.3 (15 July 2005)
1602 schoenebeck 686
1603     * packaging changes:
1604     - fixed compilation with gcc 4.0
1605    
1606 schoenebeck 687 * Gigasampler format engine:
1607     - LFO preprocessing was performed even though the respective LFO was
1608     disabled by the instrument patch (minor efficiency fix)
1609 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1610     for volume ramp downs in the same fragment (needed for current voice
1611     stealing implementation) then simply inform the user with a warning
1612     about possible click sounds and reduce the volume ramp down
1613     appropriately instead of cancelling the audio device connection
1614 schoenebeck 687
1615 schoenebeck 677 Version 0.3.2 (24 June 2005)
1616 schoenebeck 609
1617     * packaging changes:
1618     - updated autotools build files to compile on OS X
1619     (conditional compilation of CoreMIDI and MidiShare drivers)
1620 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1621     './configure --disable-asm' (definitely not recommended)
1622 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1623     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1624     (due to 'dist-bzip2' automake option)
1625 schoenebeck 649
1626     * Gigasampler format engine:
1627     - support for the gig parameters for "release velocity response" curves
1628     - fine tuning of the EGADSR envelope
1629     - volume of release triggered samples now depends on note-on velocity,
1630     note length and gig parameter "release trigger decay" instead of
1631     note-off velocity.
1632 schoenebeck 663 - revised voice stealing
1633     (fixes crash and endless loop caused by voice stealing)
1634 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1635 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1636     instead of when the respective voice is actually launched
1637     (fixes undefined behavior if stolen voices belonged to a key group -
1638     this case was followed by a "killed voice survived" error message)
1639 schoenebeck 669 - fixed minor issue with null/silence samples
1640     (those stole voices even though they don't need a voice at all which
1641     resulted in "voice stealing didn't work out" messages)
1642 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1643     instrument or audio output device change
1644 schoenebeck 654
1645 schoenebeck 620 * LSCP server:
1646 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1647 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1648 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1649 schoenebeck 609
1650 schoenebeck 668 * linuxsampler application:
1651     - added command line parameters --lscp-addr and --lscp-port to override
1652     default IP address and port of LSCP server
1653    
1654 schoenebeck 579 Version 0.3.1 (24 May 2005)
1655    
1656     * initial release
