* SFZ format engine: fixed support for regions with loccN/hiccN
  conditions on more than one MIDI controller.

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 3592 - NKSP language: Allow unary '+' operator.
185 schoenebeck 3551
186 schoenebeck 3550 * test cases:
187 schoenebeck 3548 - Fixed compiler errors in test cases.
188     - Updated README for how to compile & run test cases.
189     - Updated test case
190     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
191     expected behaviour of the Mutex class implementation (recursive
192     mutex type).
193 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
194     functions.
195 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
196 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
197     int_to_real(), real(), real_to_int() and int(), as well as for the
198     plus, minus and negate language operators.
199 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
200     'final' operator usage cases.
201     - Added NKSP test cases for (floating point tolerance aware) real number
202     equalness / unequalness comparison.
203 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
204     initialization of arrays.
205 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
206     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
207     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
208 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
209 schoenebeck 3548
210 persson 3593 * SFZ format engine:
211     - Fixed support for regions with loccN/hiccN conditions on more than one
212     MIDI controller.
213    
214 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
215 schoenebeck 3381
216     * Real-time instrument scripts:
217     - Fixed behavior of built-in NKSP functions change_sustain(),
218     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
219     and change_cutoff_release().
220    
221 schoenebeck 3444 * general changes:
222     - Only play release trigger samples on sustain pedal up if this behaviour
223     was explicitly requested by the instrument (otherwise only on note-off).
224 persson 3455 - Fixed compiler warnings.
225     - Fixed compilation error when cross-compiling to Mac.
226 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
227     (see bug #169).
228     - LSCP doc: Be more clear describing the two distinct approaches
229     of using external vs. internal effects (see bug #169).
230 schoenebeck 3514 - "optional" class: Fixed comparison operators.
231 schoenebeck 3444
232 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
233     - Format extension: If requested by instrument then don't play release
234     trigger sample on note-off events.
235    
236 schoenebeck 3487 * SFZ format engine:
237     - Fixed memory leak when releasing samples
238     (fixes bug #307, patch by Jacek Roszkowski)
239 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
240     (fixes bug #308, patch by Jacek Roszkowski).
241 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
242     (fixes bug #310, patch by Jacek Roszkowski).
243 schoenebeck 3487
244 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
245 persson 2837
246 persson 2856 * SFZ format engine:
247     - added support for <global>, <master> and #define (patch by Alby M)
248 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
249     - Added support for sfz extension opcode 'script' which may be used to
250     load real-time instrument script file (NKSP script language).
251 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
252 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
253 persson 3291 - sfz parser: allow missing space between header and opcode
254 persson 2856
255 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
256 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
257     cutoff settings.
258 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
259     all if an up-pitch of more than 40 semi tones was requested (I don't
260     think there is any stock gig sound that requires this behavior to
261     resemble its original sound).
262 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
263     be aborted (as LinuxSampler extension to the original GigaStudio 4
264     format).
265 schoenebeck 3072
266 persson 2837 * general changes:
267     - fixed printf type errors (mostly in debug messages)
268 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
269 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
270     allowing to sort data efficiently in real-time safe manner.
271     - RTList class: added methods for moving/inserting elements to arbitrary
272     position within a list.
273     - RTList class: added method fromPtr() for creating an Iterator object from
274     a raw element pointer.
275     - Attempt to partly fix resetting engine channels vs. resetting engine, an
276     overall cleanup of the Reset*(), ConnectAudioDevice(),
277     DisconnectAudioDevice() API methods would still be desirable though,
278     because the current situation is still inconsistent and error prone.
279 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
280     being directly assigned to a keyboard key. This allows more fine graded
281     processing of voices, which is i.e. required for certain instrument
282     script features.
283 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
284     (CC #64) events.
285     - Fix: Release trigger voices can now also distinguish correctly between
286     note-off and sustain pedal up events.
287 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
288     (while slow rate of crossfade smoother is preserved) to allow quick
289     volume and pan changes by instrument scripts for instance.
290 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
291     properly and thus were ignored for certain uses.
292 schoenebeck 3018 - Added new C++ API method
293     VirtualMidiDevice::SendChannelPressureToSampler().
294 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
295     sub threads is 16-byte aligned
296 schoenebeck 3054 - fixed numerous compiler warnings
297 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
298 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
299     fixes potential undefined behavior.
300 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
301     have a valid sample mapped (fixes bug #252).
302     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
303 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
304     subsequent optional argument due to glibc's implementation oddity
305     which expects a "=" sign, but no space between them.
306 persson 2837
307 schoenebeck 2866 * packaging changes:
308     - removed unnecessary dependency to libuuid
309     (originated by libgig's usage of it)
310 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
311     auto detect whether it (sh/c)ould output its messages in color.
312 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
313     substitution variable.
314     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
315 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
316     linuxsampler with instruments DB support.
317 schoenebeck 2866
318 schoenebeck 2871 * Real-time instrument scripts:
319     - Implemented scheduler for delayed MIDI events and for suspended scripts.
320     - Built-in script function "wait()": implemented support for function's
321     "duration-us" argument, thus scripts using this function are now
322     correctly resumed after the requested amount of microseconds.
323     - Built-in script function "play_note()": implemented support for
324     function's "duration-us" argument, thus notes triggered with this
325     argument are now correctly released after the requested amount of
326     microseconds.
327     - Fix: script events were not cleared when engine channel was reset,
328     potentially causing undefined behavior.
329     - Fixed crash which happened when trying to reference an undeclared
330     variable.
331 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
332     special value -1 for "duration-us" argument, which will cause the
333     triggered note to be released once the original note was released.
334 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
335     - Added new API method ScriptVM::syntaxHighlighting() which provides
336     a convenient syntax highlighting backend for external instrument
337     script editor applications.
338 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
339     - Extended parser issues to provide not only first line and first
340     column, but also last line and last column of issue (thus marking
341     the precise span of the issue within the source code).
342 schoenebeck 2902 - Reload script automatically after being modified by an instrument
343     editor.
344 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
345     like "on note end on".
346 schoenebeck 2931 - Implemented built-in script function "change_vol()".
347     - Implemented built-in script function "change_tune()".
348     - Implemented built-in script function "change_pan()".
349 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
350     - Implemented built-in script function "change_reso()".
351     - Implemented built-in script function "event_status()".
352     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
353     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
354     "event_status()" function.
355     - NKSP language: Added support for bitwise operators ".or.", ".and."
356     and ".not.".
357     - NKSP language scanner: Fixed IDs matching to require at least one
358     character (i.e. when matching function names or variable names).
359     - NKSP language scanner: disabled unusued rules.
360 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
361     be distinguished engine internally from "real" MIDI note on/off
362     events in order to avoid misbehaviors like hanging notes.

369     - NKSP language fix: division expressions were evaluated too often.
370     - NKSP language fix: string concatenation operator was right
371     associative instead of left (to right).
372 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
373     (i.e. "if end if").
374 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
375     - Implemented built-in script variable "$NI_CALLBACK_ID".
376     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
377     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

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

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

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

472 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
473     "init" event handlers.
474 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
475     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
476     to retrieve all code blocks filtered out by the preprocessor.
477 schoenebeck 3293 - Added built-in script function "fork()".
478     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
479     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
480     - Fixed potential crash when accessing dynamic built-in array variables.
481 schoenebeck 3296 - Added built-in script function "callback_status()".
482     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
483     - Added built-in constant $CALLBACK_STATUS_QUEUE.
484     - Added built-in constant $CALLBACK_STATUS_RUNNING.
485 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
486     "change_decay()" and "change_release()" to i.e. allow passing 2000000
487     for doubling the respective time.
488 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
489     to a lexer start condition stack underrun.
490     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
491     USE_CODE_IF_NOT() preprocessor statements.
492 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
493     can be set to disable all subsequent built-in "message()" function calls
494     on preprocessor level.
495 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
496 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
497     to avoid the editor app to crash on ill-formed text input.
498 schoenebeck 3335 - Added built-in script function "change_pan_time()".
499     - Added built-in script function "change_pan_curve()".

501     - Added built-in script function "change_cutoff_decay()".
502     - Added built-in script function "change_cutoff_sustain()".
503     - Added built-in script function "change_cutoff_release()".
504     - Added built-in script function "change_cutoff_lfo_depth()".
505     - Added built-in script function "change_cutoff_lfo_freq()".
506 schoenebeck 2871
507 schoenebeck 3050 * Instruments DB:
508     - Fixed memory access bug of general DB access code which lead to
509     undefined behavior.
510 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
511     - The instrument DB path of linuxsampler's --create-instruments-db argument
512     is now optional, if it is missing, then a default location is used.

514     - Added support for scanning Sound Font (.sf2) files.
515 schoenebeck 3101 - Fixed undefined DB transaction behavior.

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

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

632     key
633 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
634     - bugfix: filter keyboard tracking was broken
635     - filter performance fix (an unnecessary copy was made of the
636     filter parameters in each sub fragment)
637     - handle special case when pan parameter in gig file has max or
638     min value
639 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
640     doesn't sound naturally with a drumkit
641 persson 2408 - fixed EG1 modulation when attack or release is zero
642 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
643 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
644     conditions (see also previous commit on libgig).

665     - fine-tuned the default velocity curve
666 persson 2086 - added support for transpose
667     - fixed crash when using sw_down/up
668     - improved logic for sw_lokey/hikey/up/down/last
669     - added more v1 aliases to parser
670 persson 2091 - reduced memory usage for sfz data
671 persson 2101 - RT-safeness: avoid malloc in audio thread

1047     (labelled "Disk stream not available in time")
1048 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
1049     crashes and noise on such transitions).
1050 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1051     (fixes #208)
1052 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1053     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1054     practically irrelevant, however it caused problems with the new LSCP
1055     shell's auto completion feature).
1056 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1057     after each other (fixes #231).

1081 schoenebeck 1601 * general changes:
1082     - bugfix: on some POSIX systems instrument editor plugins refused to
1083     load as we used a non-portable Linux specific struct field
1084     (fixes bug #70, patch by Ronald Baljeu)
1085 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
1086     plugin DLL on Windows systems failed
1087 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1088     - optimized the SynchronizedConfig class so it doesn't wait
1089     unnecessarily long after an update
1090 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
1091     events (e.g. to highlight the pressed keys on the virtual keyboard
1092     of gigedit)
1093 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
1094 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
1095 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1107 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
1108     be switched on by command line option "--stacktrace" (the automatic
1109     stacktrace mechanism seems to be broken on most systems at the moment)
1110 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1111     a pointer to the launched InstrumentEditor object
1112 schoenebeck 1876 - added optional 3rd party user data parameter for following
1113     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1114     InstrumentEditor::Launch(),
1115     InstrumentManager::LaunchInstrumentEditor()
1116 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory

1123 schoenebeck 1601
1124 schoenebeck 1599 * audio driver:
1125     - removed the nonsense audio channel constraint (which was hard coded to
1126     max. 100 audio channels) for most audio drivers
1127 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1128     opposed to the LSCP specs

1130     reflected the wrong value
1131 persson 1644 - fixed a memory management bug in ASIO driver
1132 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

1134 persson 1748 jack_client_new
1135 iliev 1829 - added (experimental) CoreAudio driver
1136 persson 1888 - applied old fixes to the ASIO driver that were included in the
1137     previous binary release but accidentally never committed to CVS
1138     (fixes #117)
1139 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1140     win64)
1141 persson 1895 - VST: added support for sample rate and buffer size changes

1147     stereo
1148 persson 1922 - added channel routing, fxsends and midi maps to the settings
1149     stored in the plugin state
1150 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
1151     AudioChannel::CopyTo() methods using GCC vector exensions

1154     exception when getting parameters from a disconnected device
1155 schoenebeck 1599
1156 persson 1651 * MIDI driver:
1157     - added JACK MIDI driver
1158 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
1159     want to (mis)use it for some purpose ("fixed" in all current MIDI
1160     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1161 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1162 persson 1887 CoreMidi or AU
1163 persson 1889 - fixed mingw-w64 compilation error in MME driver
1164 persson 1924 - made program change handling in MIDI thread real-time safe by
1165     moving the logic to a non-RT thread
1166 persson 1951 - fixed minor memory leak in ALSA driver
1167 persson 1651
1168 schoenebeck 1604 * instruments database:
1169 iliev 1603 - avoid time consuming samples scanning when adding instruments
1170     to the instruments database
1171 iliev 1727 - added support for handling lost files in the instruments database
1172 iliev 1781 - Implemented option for adding instruments in separate directories
1173     in the instruments database
1174     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1175 persson 1908 - work-around for missing fnmatch function on Windows to make
1176     instrument database compilable
1177 schoenebeck 1930 - added instrument database support on Windows
1178     works with both standalone mode and VST plugin.
1179     the instruments DB file is located in
1180     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1181     databases for each windows user
1182     if no DB is present it automatically creates the .linuxsampler subdir
1183     and then creates an empty DB
1184 persson 1943 - fixed recursive import, which was broken on Windows
1185 iliev 1603
1186 persson 1644 * Gigasampler format engine:
1187     - fixed a memory leak that could happen when a channel was deleted
1188     while notes were playing
1189 persson 1646 - made it possible to load an instrument even if the audio thread
1190     isn't running
1191 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1192     enough for piano gigs with pedal noise samples
1193 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
1194     respective FX send MIDI controller was used
1195 schoenebeck 1724 - added support for GM global device volume SysEx message
1196 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1197     whole sampler [default] or only to the sampler channels that are
1198     connected to the respective MIDI input port the SysEx message arrived
1199     on)
1200 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1201     sometimes wrongly killed in the same buffer, causing no sound to
1202     be played
1203 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1204     which is usally used to switch a part between chromatic sounds and
1205     drumkit sounds (as opposed to their common default setting of MIDI
1206     part 10 being a drumkit part and all other ones chromatic parts), in
1207     LS however one can switch between the first 16 MIDI instrument maps
1208     defined for the sampler
1209 persson 1764 - made it possible to create multiple sample channels even if the
1210     audio thread isn't running
1211 persson 1844 - fixed crash when removing channel with active voices (#116)
1212 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1213     un-cache the respective sample if it's really not used by any
1214     sampler engine anymore
1215     - re-cache samples in case they were changed by an instrument editor,
1216     e.g. when a sample was added while playing (#82)
1217 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1218     same time stamp as the voice's note-on event and occured both in the
1219     same audio fragment cycle (fixes bug #112)
1220 persson 1858 - added support for the "fine tune" and "pitch bend range"
1221     instrument-level gig parameters
1222     - fixed minor artifacts in pitch bend handling
1223 schoenebeck 1860 - added support for GS Reset SysEx message
1224 persson 1862 - allow gig files to use unlimited downward pitch shifting
1225     - added a limit check for upward pitch shifting
1226 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1227     note was silent
1228 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1229     same time a new instrument was loading
1230 persson 1644
1231 schoenebeck 1687 * LSCP server:
1232     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1233     react on MIDI data arriving on certain sampler channels (so far only
1234     Note-On and Note-Off events are sent via this LSCP event)
1235 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1236     react on MIDI data arriving on certain MIDI input devices (so far only
1237     Note-On and Note-Off events are sent via this LSCP event)
1238 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1239     SET DB_INSTRUMENT FILE_PATH
1240 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1241     frontends to send MIDI messages to specific sampler channel
1242     - added two additional fields to GET FILE INSTRUMENT INFO command -
1243     KEY_BINDINGS and KEYSWITCH_BINDINGS
1244 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1245     was incorrect
1246 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1247 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1248     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1249     be triggered respectively
1250     - added new LSCP command "SET STREAMS" to globally alter the maximum
1251     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1252     which will be triggered respectively
1253 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1254     a gigedit file dialog is opened)
1255 iliev 1848 - close all connections when LSCPServer is deleted
1256 iliev 1882 - hard close of all sockets on exit
1257 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1258     driver
1259 schoenebeck 1687
1260 iliev 1761 * Bug fixes:
1261     - fixed a crash which occurs when removing a sampler channel waiting
1262     to start instrument loading after another channel
1263 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1264     instrument loading in progress (bug #113)
1265 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1266     instrument with PERSISTENT load mode
1267 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1268     - fixed memory leaks when issuing the following LSCP commands:
1269     GET AUDIO_OUTPUT_DRIVER INFO
1270     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1271     GET MIDI_INPUT_DRIVER INFO
1272     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1273     - fixed possible compilation error when sqlite is not present
1274 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1275 iliev 1847 - fixed crash when changing the audio output device of a sampler
1276     channel with loaded instrument and start playing notes
1277 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1278 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1279     PowerPC, which probably could cause crashes on that platform
1280 persson 1889 - fixed a memory management error which could cause a crash when a
1281     plugin was unloaded
1282 persson 1896 - bugfix: two private structs had the same name, which could cause
1283     problems if the linker chose the wrong constructor
1284 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1285     Windows
1286 iliev 1761
1287    
1288 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1289 schoenebeck 1454
1290     * packaging changes:
1291     - added autoconf checks for pthread library
1292     - added autoconf check for pthread bug found on certain NPTL-enabled
1293     glibc versions (see Gentoo bug report #194076)
1294 senoner 1502 - added autoconf checks for MS Windows
1295 schoenebeck 1454
1296 persson 1455 * general changes:
1297     - bugfix: the thread used by an editor plugin didn't die when the
1298     editor closed
1299 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1300     out all the space. operator--() did not apply size_mask after
1301     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1302     order to avoid problems with the _NonVolatileReader functions.
1303     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1304     GetWriteSpace(). Since this function is currently only used in
1305     the stream's qsort() compare function, it didn't trigger any
1306     bugs.
1307     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1308     24bit mode too. Faster method to read 24bit words on little
1309     endian machines (x86): replaced 3 byte reads + shifts with a 1
1310     unaligned 32bit read and shift
1311     - experimental support for MS Windows (MIDI input via MME, AUDIO
1312     output via ASIO)
1313     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1314 iliev 1541 - support for monitoring the total number of active disk streams
1315     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1316     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1317 persson 1455
1318 senoner 1500 * AUDIO driver:
1319 persson 1534 - added Windows ASIO low latency audio driver
1320 senoner 1500
1321 senoner 1485 * MIDI driver:
1322 schoenebeck 1495 - added MME Windows MIDI driver
1323 senoner 1485
1324 schoenebeck 1471 * LSCP server:
1325     - added support for Windows style path / filenames, however with
1326     forward slash path separators instead of backslash
1327     (i.e. "C:/foo/bar.gig")
1328 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1329     apostrophes as well
1330 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1331     "LIST FILE INSTRUMENTS <file>" and
1332     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1333     about an arbitrary instrument file on the system where the sampler is
1334     running on
1335 schoenebeck 1471
1336 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1337 schoenebeck 947
1338 schoenebeck 1065 * packaging changes:
1339 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1340     API header files anymore
1341 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1342     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1343 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1344     capable to execute our autoconf environment, thus no need anymore
1345     to maintain the compile time configuration file (osx/version.h) for
1346     OSX manually (patch by Toshi Nagata)
1347 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1348     parameters
1349 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1350     C++ API header files, all implementation internal global definitions
1351     are now in global_private.h
1352     - atomic.h is not exposed to the C++ API anymore
1353     - no need to include config.h anymore for using LS's API header files
1354     - fixed warnings in API doc generation
1355 schoenebeck 1065
1356 schoenebeck 947 * general changes:
1357     - replaced the old, confusing MIDI program change mechanism by a
1358     flexible MIDI instrument mapper which allows to map arbitrary
1359 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1360 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1361     loaded on the respective channel when such MIDI program change
1362     messages arrive, beside that, each entry allows to define a life-time
1363     strategy for the instrument, so the user can define whether the
1364     instrument should i.e. be permanently loaded (to be able to switch
1365     quickly among sounds) or i.e. loaded just on demand when the
1366     respective program change arrives (to safe RAM space), as well as a
1367     global volume factor for each entry, so the user can adjust the volume
1368     dynamic of his mapped instrument collection without having to modify
1369 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1370     MIDI instrument maps and assign each sampler channel individually
1371     a certain map, so that i.e. separation of normal instruments and
1372     drumkits is possible
1373 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1374     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1375 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1376     due to a constant size RingBuffer FIFO which is now replaced by a
1377     dynamic (unlimited) size std::list FIFO
1378 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1379     output channels for being processed by external effect processors
1380     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1381     controllers
1382 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1383 iliev 1130 - Implemented new, improved notification system
1384 schoenebeck 1149 - fixed compilation errors regarding OSX
1385     (patch by Toshi Nagata)
1386 iliev 1161 - implemented instruments database
1387 iliev 1345 - added support for escape sequences to the instruments database
1388 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1389     within the sampler's process (by using instrument editor plugins),
1390     you'll notice the new "Registered instrument editors:" message on
1391 schoenebeck 1407 startup, added a new LSCP command:
1392     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1393 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1394     given sampler channel, the plugin path can be overridden at compile
1395     time with ./configure --enable-plugin-dir=/some/dir
1396 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1397     in the sampler's process to safely edit instruments while playing
1398     without a crash (hopefully) by either suspending single regions
1399     wherever possible or if unavoidable whole engine(s)
1400 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1401     policy and priority on thread level, set a minimum stack size for
1402     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1403     threads simply inherited properties of starting thread instead of
1404     setting their own policy and priority
1405 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1406     main process did not wait for the stack trace process to finish
1407     its output
1408 persson 1248 - fixed some minor memory leaks
1409 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1410     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1411 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1412     register, to avoid relocations in the text segment at runtime)
1413 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1414 schoenebeck 947
1415     * MIDI driver:
1416     - dispatch bank select (MSB and LSB) messages
1417    
1418 schoenebeck 1049 * audio driver:
1419     - the ALSA audio output driver parameters now reflect the correct
1420     parameter value ranges for the respective selected sound card
1421     (patch by Till Wimmer, a bit fixed and extended)
1422    
1423 persson 951 * Gigasampler format engine:
1424     - if a filter is used and EG2 finishes before EG1, let the voice
1425     die when EG2 has finished (this fixes a problem with clicks and
1426     voice starvation for some gigs)
1427 persson 1038 - playback is no longer disabled during instrument loading
1428     - all notes playing on a channel that changes its instrument keep
1429     playing with the old instrument until they get a note off
1430     command
1431 persson 1039 - EG fix: a release value of zero could cause noises or crash
1432 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1433 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1434     above max sustain level, which means that there is a decay phase
1435     even if sustain is 100%
1436 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1437     noises or crashes
1438 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1439 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1440     supplied to the configure script (fixes #46)
1441 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1442     instead of a fix value
1443 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1444     127 (solo mode) only kill voices if the respective mode really
1445     changed
1446 persson 951
1447 schoenebeck 1244 * LSCP server:
1448     - fixed compile time error for old Bison versions
1449     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1450 schoenebeck 1245 - parser now supports extended ASCII character set
1451     (up to ASCII code 255, i.e. includes now umlauts and accents)
1452     - filename arguments in LSCP commands now allow to use escape
1453     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1454     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1455     code value like \xf2) (fixes bug #24)
1456 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1457     least one of their text-based parameters (i.e. name, description):
1458     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1459     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1460     "SET DB_INSTRUMENT_DIRECTORY NAME",
1461     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1462     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1463     "FIND DB_INSTRUMENT_DIRECTORIES"
1464 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1465     occured, the unexpected character and the actually expected, possible
1466     character(s), the latter only if less than 5 possibilities)
1467 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1468     settings
1469 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1470     of strings were treated as being one string containing commas
1471     (fixes #57)
1472 schoenebeck 1244
1473 iliev 959 * Bug fixes:
1474     - fixed crash occurring on certain LSCP scripts (Bug 39)
1475 persson 1038 - another thread safety fix for lscp "load engine" and "set
1476     channel audio output device"
1477 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1478     on a sampler channel with connected MIDI device
1479 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1480     device connected to a sampler channel to number less then or equal
1481     to the index of the port to which the sampler channel is connected.
1482 iliev 1296 - The previous bindings were not been disconnected when altering
1483     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1484     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1485 iliev 1297 - The active stream/voice count statistic was incorrect.
1486 iliev 1298 - notification events were not been sent for some sampler
1487     channel changes
1488 iliev 1305 - added default min and max values to restrict the number of allowed
1489     audio output channels and MIDI input ports
1490 iliev 1306 - the connection to the PCM interface is now closed when destroying
1491     an audio output device
1492 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1493 iliev 959
1494 schoenebeck 1221 * test cases:
1495     - updated and fixed (haven't been touched in a while)
1496    
1497 schoenebeck 937 Version 0.4.0 (24 November 2006)
1498 persson 696
1499 schoenebeck 697 * packaging changes:
1500 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1501     to post-(un)install steps; added devel package for liblinuxsampler;
1502     to linuxsampler.spec (RPM)
1503 schoenebeck 697 - install necessary development header files for allowing 3rd party
1504     applications to link against liblinuxsampler
1505     - liblinuxsampler's API documentation can be generated with 'make docs'
1506     (Doxygen required)
1507 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1508     implementation (currently either an integer math solution or a
1509     di-harmonic approximation), automatic detection can be overriden
1510     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1511     configure script argument though (mandatory for cross-compilation)
1512 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1513     provided some on his own (as CXXFLAGS)
1514 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1515     messages
1516 schoenebeck 852 - added compile time options to allow disabling the various audio and
1517     MIDI drivers
1518 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1519     (patch by Ebrahim Mayat)
1520 schoenebeck 697
1521 persson 696 * Gigasampler format engine:
1522 schoenebeck 738 - extensive synthesis optimization
1523     (reimplementation of EGs and LFO(s), removed synthesis parameter
1524     prerendering and the synthesis parameter matrix in general, splitting
1525     each audio fragment into subfragments now where each subfragment uses
1526 persson 830 constant pitch and filter coefficients. The volume coefficient is
1527     linearly interpolated inside a subfragment, unless
1528     --disable-interpolate-volume is set.)
1529 persson 696 - fine tuning of the EG modulation parameters
1530 persson 729 - improved filter cutoff calculation by adding support for the
1531     following gig parameters: Cutoff freq (used when no cutoff
1532     controller is defined), Control invert, Minimum cutoff, Velocity
1533 persson 791 curve and Velocity range. The keyboard tracking now scales
1534     cutoff frequency instead of resonance.
1535 persson 877 - added support for gig parameter Resonance.
1536 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1537 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1538     which can be overridden with --enable-global-attenuation
1539 persson 783 - EG fixes: made the length of "attack hold" stage more
1540     accurate. Release stage can now start before attack stage
1541 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1542     time now has a minimal value to prevent clicks.
1543 persson 799 - fixed pitch changes larger than one octave
1544 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1545     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1546     all modes can be altered via standard GM messages, that is CC5 for
1547     altering portamento time, CC65 for enabling / disabling portamento
1548     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1549 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1550     parameter) and crossfade
1551 persson 831 - added support for the "attenuation controller threshold" gig
1552     parameter
1553 persson 832 - added smoothing of volume changes caused by control change
1554     messages
1555 persson 865 - sample loop parameters are now taken from the DimensionRegion
1556     instead of the wave chunk
1557     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1558     not equal to a power of two
1559 persson 877 - reimplementation of the filter algorithm. The new filter is more
1560     accurate and supports all gig filter types, including bandreject
1561     and lowpass turbo.
1562 persson 903 - real support for 24 bit samples - samples are not truncated to
1563     16 bits anymore
1564     - support for aftertouch (channel pressure, not polyphonic
1565     aftertouch)
1566 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1567     amplifying from 0)
1568 persson 696
1569 schoenebeck 711 * LSCP server:
1570     - fixed application exit on broken pipe error (fixes bug #20)
1571 iliev 793 - fixed the notification messages delay due to lack of
1572     network activity (fixes bug #26)
1573 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1574     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1575 schoenebeck 711
1576 schoenebeck 838 * audio driver:
1577     - added aRts audio output driver (by no means RT safe)
1578    
1579 schoenebeck 775 * MIDI driver:
1580     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1581     messages several times instead of once
1582 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1583     for events (i.e. for offline rendering based MIDI drivers)
1584 persson 922 - added checks for bad MIDI data
1585 schoenebeck 775
1586 schoenebeck 900 * linuxsampler application:
1587     - show available sampler engine types on startup
1588    
1589 schoenebeck 705 * general changes:
1590     - support for muting sampler channels and solo mode of the same, two new
1591     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1592     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1593     introduced for this, the behavior is the same like on a mixer console
1594 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1595     --enable-process-muted-channels which can be used to enable the
1596     processing of muted channels.
1597 iliev 777 - support for sostenuto pedal
1598 iliev 779 - support for monitoring the total number of active voices
1599 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1600     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1601 persson 835 - fixed some memory management errors
1602 persson 841 - fixed some concurrency problems that could lead to crashes when
1603     LSCP commands were executed
1604 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1605     sampler channel (fixes bug #36)
1606 schoenebeck 705
1607 schoenebeck 692 Version 0.3.3 (15 July 2005)
1608 schoenebeck 686
1609     * packaging changes:
1610     - fixed compilation with gcc 4.0
1611    
1612 schoenebeck 687 * Gigasampler format engine:
1613     - LFO preprocessing was performed even though the respective LFO was
1614     disabled by the instrument patch (minor efficiency fix)
1615 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1616     for volume ramp downs in the same fragment (needed for current voice
1617     stealing implementation) then simply inform the user with a warning
1618     about possible click sounds and reduce the volume ramp down
1619     appropriately instead of cancelling the audio device connection
1620 schoenebeck 687
1621 schoenebeck 677 Version 0.3.2 (24 June 2005)
1622 schoenebeck 609
1623     * packaging changes:
1624     - updated autotools build files to compile on OS X
1625     (conditional compilation of CoreMIDI and MidiShare drivers)
1626 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1627     './configure --disable-asm' (definitely not recommended)
1628 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1629     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1630     (due to 'dist-bzip2' automake option)
1631 schoenebeck 649
1632     * Gigasampler format engine:
1633     - support for the gig parameters for "release velocity response" curves
1634     - fine tuning of the EGADSR envelope
1635     - volume of release triggered samples now depends on note-on velocity,
1636     note length and gig parameter "release trigger decay" instead of
1637     note-off velocity.
1638 schoenebeck 663 - revised voice stealing
1639     (fixes crash and endless loop caused by voice stealing)
1640 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1641 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1642     instead of when the respective voice is actually launched
1643     (fixes undefined behavior if stolen voices belonged to a key group -
1644     this case was followed by a "killed voice survived" error message)
1645 schoenebeck 669 - fixed minor issue with null/silence samples
1646     (those stole voices even though they don't need a voice at all which
1647     resulted in "voice stealing didn't work out" messages)
1648 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1649     instrument or audio output device change
1650 schoenebeck 654
1651 schoenebeck 620 * LSCP server:
1652 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1653 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1654 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1655 schoenebeck 609
1656 schoenebeck 668 * linuxsampler application:
1657     - added command line parameters --lscp-addr and --lscp-port to override
1658     default IP address and port of LSCP server
1659    
1660 schoenebeck 579 Version 0.3.1 (24 May 2005)
1661    
1662     * initial release
