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

1 Version SVN trunk (?)
2
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++14 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++14 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++14).
10 - 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
14 * 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 - 64 bit support for NKSP integer scripts variables (declare $foo).
21 - 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 - NKSP script editor API: Added support for detecting standard unit tokens
40 and their potential metric prefix token.
41 - 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 - Allow built-in exit() function to potentially accept real number type
54 argument as well.
55 - 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 - 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 - 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 - 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 - 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 - 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 - 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 - 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 - NKSP language: Allow unary '+' operator.
185
186 * test cases:
187 - 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 - Added test cases for NKSP core language aspects and core built-in
194 functions.
195 - Fixed thread tests segfaulting on Linux.
196 - 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 - 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 - Added NKSP int array and real array tests for value assignment and
204 initialization of arrays.
205 - 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 - Added NKSP test cases for unary '+' operator.
209
210 * SFZ format engine:
211 - Fixed support for regions with loccN/hiccN conditions on more than one
212 MIDI controller.
213
214 Version 2.1.1 (27 Jul 2019)
215
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 * 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 - Fixed compiler warnings.
225 - Fixed compilation error when cross-compiling to Mac.
226 - 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 - "optional" class: Fixed comparison operators.
231
232 * 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 * SFZ format engine:
237 - Fixed memory leak when releasing samples
238 (fixes bug #307, patch by Jacek Roszkowski)
239 - Fixed potential crash when a sample is shared by more than one region
240 (fixes bug #308, patch by Jacek Roszkowski).
241 - Opcode 'sample': Added support for built-in sample '*silence'
242 (fixes bug #310, patch by Jacek Roszkowski).
243
244 Version 2.1.0 (25 Nov 2017)
245
246 * SFZ format engine:
247 - added support for <global>, <master> and #define (patch by Alby M)
248 - 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 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
252 - Fixed unintended volume fade-in of voices under certain conditions.
253 - sfz parser: allow missing space between header and opcode
254
255 * Gigasampler/GigaStudio format engine:
256 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
257 cutoff settings.
258 - 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 - Added support for controlling whether the individual EGADSR stages may
263 be aborted (as LinuxSampler extension to the original GigaStudio 4
264 format).
265
266 * general changes:
267 - fixed printf type errors (mostly in debug messages)
268 - use unique_ptr instead of auto_ptr when building with C++11
269 - 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 - 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 - 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 - 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 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
291 properly and thus were ignored for certain uses.
292 - Added new C++ API method
293 VirtualMidiDevice::SendChannelPressureToSampler().
294 - windows, 32-bit: fixed potential crashes by making sure the stack in
295 sub threads is 16-byte aligned
296 - fixed numerous compiler warnings
297 - Fixed invalid (note-on) event ID being assigned to new Note objects.
298 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
299 fixes potential undefined behavior.
300 - 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 - 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
307 * packaging changes:
308 - removed unnecessary dependency to libuuid
309 (originated by libgig's usage of it)
310 - 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 - Debian: Fixed packaging error about invalid "Source-Version"
313 substitution variable.
314 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
315 - Debian: Added build dependency to libsqlite3-dev for building
316 linuxsampler with instruments DB support.
317
318 * 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 - 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 - 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 - 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 - Reload script automatically after being modified by an instrument
343 editor.
344 - NKSP language grammar correction: allow empty event handler bodies
345 like "on note end on".
346 - Implemented built-in script function "change_vol()".
347 - Implemented built-in script function "change_tune()".
348 - Implemented built-in script function "change_pan()".
349 - 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 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
354 "event_status()" function.
355 - NKSP language: Added support for bitwise operators ".or.", ".and."
356 and ".not.".
357 - NKSP language scanner: Fixed IDs matching to require at least one
358 character (i.e. when matching function names or variable names).
359 - NKSP language scanner: disabled unusued rules.
360 - Fixed behavior of play_note() and note_off() functions which must
361 be distinguished engine internally from "real" MIDI note on/off
362 events in order to avoid misbehaviors like hanging notes.
363 - Implemented built-in script variable "$KSP_TIMER".
364 - Implemented built-in script variable "$NKSP_REAL_TIMER".
365 - Implemented built-in script variable "$NKSP_PERF_TIMER".
366 - Implemented built-in script variable "$ENGINE_UPTIME".
367 - Implemented built-in script function "inc()".
368 - Implemented built-in script function "dec()".
369 - NKSP language fix: division expressions were evaluated too often.
370 - NKSP language fix: string concatenation operator was right
371 associative instead of left (to right).
372 - NKSP language correction: allow empty statements in entire language
373 (i.e. "if end if").
374 - Implemented built-in script function "stop_wait()".
375 - Implemented built-in script variable "$NI_CALLBACK_ID".
376 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
377 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
378 - Added support for read-only built-in variables (respectively
379 handled by the script parser).
380 - Added built-in script constant "$NI_CB_TYPE_INIT".
381 - Added built-in script constant "$NI_CB_TYPE_NOTE".
382 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
383 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
384 - NKSP Language: Added support for user defined script functions.
385 - Implemented built-in script function "change_attack()".
386 - Implemented built-in script function "change_decay()".
387 - Implemented built-in script function "change_release()".
388 - 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 - Implemented built-in script function "sh_left()".
395 - Implemented built-in script function "sh_right()".
396 - Implemented built-in script function "min()".
397 - Implemented built-in script function "max()".
398 - NKSP Fix: "init" event handler was not always executed when a script
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 - ScriptVM: Implemented automatic suspension of RT safety
405 threatening scripts.
406 - Provide more user friendly error messages on syntax errors.
407 - Fixed NKSP parser warning "Not a statement" when assigning an
408 initializer list to an array variable.
409 - Implemented built-in script array variable "%ALL_EVENTS".
410 - Implemented built-in script function "in_range()".
411 - Implemented built-in script function "change_amp_lfo_depth()".
412 - Implemented built-in script function "change_amp_lfo_freq()".
413 - Implemented built-in script function "change_pitch_lfo_depth()".
414 - Implemented built-in script function "change_pitch_lfo_freq()".
415 - Implemented built-in script function "change_vol_time()".
416 - Implemented built-in script function "change_tune_time()".
417 - Implemented built-in script function "fade_in()".
418 - Implemented built-in script function "fade_out()".
419 - Fixed acceptance of wrong data type of parameters passed to built-in
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 - 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 - Fixed a bunch of scheduler time related bugs.
429 - Fixed polyphonic variables not being reset to zero after usage.
430 - Built-in "ignore_event()" function: argument is now optional, like with
431 built-in function "ignore_controller()".
432 - Implemented built-in script function "change_velo()".
433 - Implemented built-in script function "change_note()".
434 - 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 - 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.

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 - 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 - 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 - Implemented built-in script function "change_play_pos()".
464 - NKSP language: Added support for user declared const array variables.
465 - NKSP language: Raise parser warning if array variable is accessed with
466 an index that exceeds the array's size.
467 - NKSP language fix: Unknown characters were not handled correctly.
468 - NKSP language: Added support for "synchronized .. end synchronized"
469 code blocks.
470 - Implemented built-in script function "abort()" which allows to abort
471 another script handler by passing its callback ID.
472 - Fixed potential memory access bug and potential undefined behavior of
473 "init" event handlers.
474 - 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 - 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 - 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 - 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 - 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 - 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 - Implemented built-in script function "change_sustain()".
496 - 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 - Added built-in script function "change_pan_time()".
499 - Added built-in script function "change_pan_curve()".

507 * Instruments DB:
508 - Fixed memory access bug of general DB access code which lead to
509 undefined behavior.
510 - 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.
513 - Added support for scanning SFZ (.sfz) files.
514 - Added support for scanning Sound Font (.sf2) files.
515 - Fixed undefined DB transaction behavior.

534 - fixed compilation with gcc 4.7
535 - fixed configure script error with old autoconf versions

538 - modernized configure script
539 - fixed linkage error when building with
540 LDFLAGS="-Wl,--no-undefined" (#190)

556
557 * general changes:
558 - Refactoring: moved the independent code from
559 the Gigasampler format engine to base classes
560 - command line option '--profile' is currently disabled, since the
561 respective profiling code is currently broken
562 - 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 - 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 - implemented support for internal LADSPA effects
577 - raised limit of program change queue from 100 to 512
578 (as suggested by Alex Stone)
579 - implemented sine LFO, pulse LFO and saw LFO
580 - experimental support for per voice equalization
581 - added command line option --exec-after-init
582 - 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 - 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 - Various "const" and "restrict" optimizations.
593 - 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 - added a lock guard class for exception safe mutex handling and
597 used it everywhere appropriate
598 - 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 - 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 - 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 - Bugfix: only process the latest MIDI program change event.
613 - Introducing the LSCP shell, which provides convenient control of the
614 sampler from the command line by providing LSCP aware features.
615 - VirtualMidiDevice: Added support for program change.
616 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
617 - VirtualMidiDevice: Added support for pitch bend.
618 - 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 - 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

632 key
633 - 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 - Exclusive Groups: don't ever stop voices of the same note,
640 doesn't sound naturally with a drumkit
641 - fixed EG1 modulation when attack or release is zero
642 - Fixed support for 'aftertouch' attenuation controller.
643 - Fixed crash that happened with velocity split sounds under certain
644 conditions (see also previous commit on libgig).
645 - fixed behaviour of filter LFO
646
647 * SFZ format engine:

677 - added support for loop_mode=one_shot
678 - fixed playback of 16 bit wav files on big endian CPUs
679 - added support for Ogg Vorbis sample files
680 - use loop markers from sample file if loop_start and loop_end are
681 not set in sfz file
682 - implemeted filters. Filter types: lowpass, bandpass, bandreject
683 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,

839 loaded a second time (this time it's for Linux and Mac, previous
840 similar fix was for Windows)
841 - thread safety fixes for the instrument loading thread
842 - LV2: use the new lv2 package if present

860 informations like the EngineChannel for which the instrument editor was
861 spawned for. This allows the instrument editors to interact more actively
862 with the sampler.
863
864 * MIDI driver:
865 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
866 the ALSA sequencer client name

868 there is no reason for this limit
869 - MME: fixed memory handling bug found with cppcheck
870 - MME: removed compiler warning
871 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
872 which allows to retrieve the list of CoreMIDI clients / ports and to connect
873 to them a la JACK, via the usual sampler APIs
874 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
875 the driver will automatically connect to other CoreMIDI clients' ports
876 (e.g. external MIDI devices being attached to the Mac)
877 - added support for MIDI note on velocity filter
878 - CoreMIDI: fixed memory deallocation error
879 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
880 virtual keyboards in frontends / instrument editors being stuck.
881 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
882 - Implemented missing handling of MIDI "running status".
883 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
884 - MME bugfix: driver wasn't closed properly
885 - CoreMIDI: automatically connect to all input sources by default (driver
886 parameter "AUTO_BIND").

1000 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1001 (i.e. return value of new script function "by_marks()").
1002 - Pass/preserve polyphonic variable data from respective "note" event
1003 handler to "release" event handler.
1004 - Fixed crash when using built-in script function "by_marks()".
1005

1010 channel to a different engine type
1011 - fixed crash when deleting a sampler channel or changing engine
1012 type while an instrument load was in progress
1013 - bugfix: playing a note while changing the instrument could cause
1014 a crash, or give "Handing back unknown region" error messages
1015 - bugfix: calling SET VOICES (which Fantasia does on start and
1016 refresh) could cause instruments to be unloaded
1017 - Mac OS X: fixed name collision of enum in EffectControl and
1018 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1019 - Mac OS X: fixed hanging threads
1020 - Windows: disabled the previous thread fix on non-Mac systems, as
1021 it caused hanging threads on Windows
1022 - Fixed possible crashes due to corrupted MIDI/audio device list
1023 after MIDI/audio device creation failure
1024 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1025 instruments were uselessly precached with zero samples, however it still
1026 took the full preloading time and on 1st program change the respective
1027 instrument was completely reloaded again.
1028 - fixed handling of rapid bank select and program change messages
1029 sent to the same sampler channel (patch from the Open Octave
1030 project, slightly adjusted)
1031 - fixed crash when trying to create an effect instance with controls
1032 which min and/or max values depend on the sample rate

1045 playing a note in a key group
1046 - fixed erroneous error message piping in VoiceBase.h
1047 (labelled "Disk stream not available in time")
1048 - Update effects on sample rate & period size changes (to avoid
1049 crashes and noise on such transitions).
1050 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1051 (fixes #208)
1052 - 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 - Fixed MIDI program change messages being ignored if quickly executed
1057 after each other (fixes #231).
1058
1059 Version 1.0.0 (31 July 2009)
1060
1061 * packaging changes:
1062 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1063 causing e.g. the libgig test to fail when
1064 "./configure --disable-jack-driver" was used
1065 (patch by Alexis Ballier)
1066 - fixed compilation with gcc 4.3
1067 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1072 - minor fix in configure for mmsystem.h detection on MinGW
1073 - Windows: look for editor plugins and Fantasia using base
1074 directory of liblinuxsampler dll (look in the same directory and one
1075 directory above)
1076 - configure script fix: removed unconditional use of SSE
1077 - fixed building with sqlite installed in a non-standard directory
1078 - when cross-compiling, don't try to create instruments.db
1079 - fix for new mingw-w64 version, which has usleep
1080
1081 * 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 - fixed endless loop which occured when loading an instrument editor
1086 plugin DLL on Windows systems failed
1087 - 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 - 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 - added support for triggering notes by instrument editors (see above)
1094 - be verbose on DLL load errors (on Linux)
1095 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1096 is only used by very few systems, most pick the int math
1097 implementation, which is usually faster)
1098 - fixes for audio drivers with varying buffer sizes
1099 - experimental support for running LinuxSampler as a DSSI, LV2 and
1100 VST plugin
1101 - notification events for stream/voice count statistics are now sent
1102 only when there are actual changes
1103 - added memory ordering constraints to improve stability on
1104 multi-core and multi-cpu systems
1105 - maximum voices and disk streams can now be altered at runtime
1106 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1107 - 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 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1111 a pointer to the launched InstrumentEditor object
1112 - added optional 3rd party user data parameter for following
1113 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1114 InstrumentEditor::Launch(),
1115 InstrumentManager::LaunchInstrumentEditor()
1116 - theoretical fix: made SynchronizedConfig follow C++0x memory
1117 model more strictly
1118 - fixes for using large audio device buffers
1119 - Windows: add the installation directory to the DLL search path
1120 when loading an editor plugin (solves problems with VST and
1121 gigedit on systems with other GTK versions installed)
1122 - updated linuxsampler man page
1123
1124 * audio driver:
1125 - removed the nonsense audio channel constraint (which was hard coded to
1126 max. 100 audio channels) for most audio drivers
1127 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1128 opposed to the LSCP specs
1129 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1130 reflected the wrong value
1131 - fixed a memory management bug in ASIO driver
1132 - Makefile fix: JACK_CFLAGS wasn't used
1133 - JACK: use jack_client_open instead of the deprecated
1134 jack_client_new
1135 - added (experimental) CoreAudio driver
1136 - 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 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1140 win64)
1141 - VST: added support for sample rate and buffer size changes
1142 - VST: close editor (Fantasia) when the VST is removed
1143 - VST: avoid opening Fantasia more than once for each VST instance
1144 - VST: export main function as "main" on Linux too (fix for
1145 energyXT)
1146 - VST: changed number of output channels from one stereo to 16
1147 stereo
1148 - added channel routing, fxsends and midi maps to the settings
1149 stored in the plugin state
1150 - performance optimization of AudioChannel::MixTo() and
1151 AudioChannel::CopyTo() methods using GCC vector exensions
1152 (if available)
1153 - ASIO fixes: avoid initializing the device twice, avoid throwing
1154 exception when getting parameters from a disconnected device
1155
1156 * MIDI driver:
1157 - added JACK MIDI driver
1158 - 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 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1162 CoreMidi or AU
1163 - fixed mingw-w64 compilation error in MME driver
1164 - made program change handling in MIDI thread real-time safe by
1165 moving the logic to a non-RT thread

1174 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1175 - work-around for missing fnmatch function on Windows to make
1176 instrument database compilable
1177 - 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 - fixed recursive import, which was broken on Windows
1185
1186 * Gigasampler format engine:
1187 - fixed a memory leak that could happen when a channel was deleted
1188 while notes were playing
1189 - made it possible to load an instrument even if the audio thread
1190 isn't running
1191 - added partial support for the "Controller Triggered" MIDI rule,
1192 enough for piano gigs with pedal noise samples
1193 - minor fix: only mark FX sends as being modified if really the
1194 respective FX send MIDI controller was used
1195 - added support for GM global device volume SysEx message
1196 (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 - 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 - 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 - made it possible to create multiple sample channels even if the
1210 audio thread isn't running
1211 - fixed crash when removing channel with active voices (#116)
1212 - 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 - 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 - added support for the "fine tune" and "pitch bend range"
1221 instrument-level gig parameters
1222 - fixed minor artifacts in pitch bend handling
1223 - added support for GS Reset SysEx message
1224 - allow gig files to use unlimited downward pitch shifting
1225 - added a limit check for upward pitch shifting
1226 - bugfix: sometimes, when playing a note twice fast, the second
1227 note was silent
1228 - fixed crash happening when a pitch bend event arrived at the
1229 same time a new instrument was loading
1230
1231 * 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 - 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 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1239 SET DB_INSTRUMENT FILE_PATH
1240 - 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 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1245 was incorrect
1246 - Optimized the retrieval of the MIDI instrument mappings
1247 - 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 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1254 a gigedit file dialog is opened)
1255 - close all connections when LSCPServer is deleted
1256 - hard close of all sockets on exit
1257 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1258 driver
1259
1260 * Bug fixes:
1261 - fixed a crash which occurs when removing a sampler channel waiting
1262 to start instrument loading after another channel
1263 - fixed a crash which occurs when removing a sampler channel with
1264 instrument loading in progress (bug #113)
1265 - fixed termination caused by uncaught exception when adding MIDI
1266 instrument with PERSISTENT load mode
1267 - 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 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1275 - fixed crash when changing the audio output device of a sampler
1276 channel with loaded instrument and start playing notes
1277 - fixed endless loop in Engine::SuspendAll() (bug #120)
1278 - fixed a low-level atomic load function that was broken on 64-bit
1279 PowerPC, which probably could cause crashes on that platform
1280 - fixed a memory management error which could cause a crash when a
1281 plugin was unloaded
1282 - bugfix: two private structs had the same name, which could cause
1283 problems if the linker chose the wrong constructor
1284 - fixed low-level ConditionServer usage bug that caused lockups on
1285 Windows
1286
1287
1288 Version 0.5.1 (6 December 2007)

1292 - added autoconf check for pthread bug found on certain NPTL-enabled
1293 glibc versions (see Gentoo bug report #194076)
1294 - added autoconf checks for MS Windows
1295
1296 * general changes:
1297 - bugfix: the thread used by an editor plugin didn't die when the
1298 editor closed
1299 - 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 - 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
1318 * AUDIO driver:
1319 - added Windows ASIO low latency audio driver
1320
1321 * MIDI driver:
1322 - added MME Windows MIDI driver
1323
1324 * 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 - allow naughty liblscp to send non-string device parameters within
1329 apostrophes as well
1330 - 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
1336 Version 0.5.0 (15 October 2007)
1337
1338 * packaging changes:
1339 - config.h is not going to be installed along with liblinuxsampler's
1340 API header files anymore
1341 - only the API relevant header (and source) files will be exported to
1342 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1343 - 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 - fixed buggy boolean --enable-foo / --disable-foo configure script
1348 parameters
1349 - 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
1356 * general changes:
1357 - replaced the old, confusing MIDI program change mechanism by a
1358 flexible MIDI instrument mapper which allows to map arbitrary
1359 (MIDI bank, MIDI program) pairs with arbitrary
1360 (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 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 - new notification events for tracking changes to audio/MIDI devices,
1374 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1375 - 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 - 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 - global (sampler wide) volume can now be controlled at runtime
1383 - Implemented new, improved notification system
1384 - fixed compilation errors regarding OSX
1385 (patch by Toshi Nagata)
1386 - implemented instruments database
1387 - added support for escape sequences to the instruments database
1388 - 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 startup, added a new LSCP command:
1392 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1393 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 - 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 - 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 - 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 - fixed some minor memory leaks
1409 - reenabled assembly features support, at the moment only for
1410 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1411 - minor assembly fix in x86 features detection (don't use the PIC
1412 register, to avoid relocations in the text segment at runtime)
1413 - POSIX callback functions of Thread.h are hidden
1414
1415 * MIDI driver:
1416 - dispatch bank select (MSB and LSB) messages
1417
1418 * 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 * 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 - 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 - EG fix: a release value of zero could cause noises or crash
1432 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1433 - 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 - more EG fixes: the level could sometimes go below zero and cause
1437 noises or crashes
1438 - minor fix of EGDecay (patch by Toshi Nagata)
1439 - fixed compiler error when --enable-override-filter-type was
1440 supplied to the configure script (fixes #46)
1441 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1442 instead of a fix value
1443 - 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
1447 * 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 - 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 - 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 - 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 - made sure that LSCP syntax is not affected by gigedit locale
1468 settings
1469 - bugfix regarding strings parameter lists: all comma separated lists
1470 of strings were treated as being one string containing commas
1471 (fixes #57)
1472
1473 * Bug fixes:
1474 - fixed crash occurring on certain LSCP scripts (Bug 39)
1475 - another thread safety fix for lscp "load engine" and "set
1476 channel audio output device"
1477 - fixed a crash which occurs when reassigning the same engine
1478 on a sampler channel with connected MIDI device
1479 - 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 - 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 - The active stream/voice count statistic was incorrect.
1486 - notification events were not been sent for some sampler
1487 channel changes
1488 - added default min and max values to restrict the number of allowed
1489 audio output channels and MIDI input ports
1490 - the connection to the PCM interface is now closed when destroying
1491 an audio output device
1492 - files with slash in their path or filename could not be loaded
1493
1494 * test cases:
1495 - updated and fixed (haven't been touched in a while)
1496
1497 Version 0.4.0 (24 November 2006)
1498
1499 * packaging changes:
1500 - 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 - 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 - 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 - do not automatically pick optimized gcc flags if the user already
1513 provided some on his own (as CXXFLAGS)
1514 - added compile time option to disable processing of All-Notes-Off MIDI
1515 messages
1516 - added compile time options to allow disabling the various audio and
1517 MIDI drivers
1518 - fixed automatic GCC CPU switch detection on PPC
1519 (patch by Ebrahim Mayat)
1520
1521 * Gigasampler format engine:
1522 - 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 constant pitch and filter coefficients. The volume coefficient is
1527 linearly interpolated inside a subfragment, unless
1528 --disable-interpolate-volume is set.)
1529 - fine tuning of the EG modulation parameters
1530 - 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 curve and Velocity range. The keyboard tracking now scales
1534 cutoff frequency instead of resonance.
1535 - added support for gig parameter Resonance.
1536 - fixed bug in sysex handling (patch by Juan Linietsky)
1537 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1538 which can be overridden with --enable-global-attenuation
1539 - EG fixes: made the length of "attack hold" stage more
1540 accurate. Release stage can now start before attack stage
1541 ends. Cancel release didn't work when sustain was zero. Attack
1542 time now has a minimal value to prevent clicks.
1543 - fixed pitch changes larger than one octave
1544 - 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 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1550 parameter) and crossfade
1551 - added support for the "attenuation controller threshold" gig
1552 parameter
1553 - added smoothing of volume changes caused by control change
1554 messages
1555 - 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 - 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 - 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 - LFO1 behaviour fixed (dampening from max volume instead of
1567 amplifying from 0)
1568
1569 * LSCP server:
1570 - fixed application exit on broken pipe error (fixes bug #20)
1571 - fixed the notification messages delay due to lack of
1572 network activity (fixes bug #26)
1573 - 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
1576 * audio driver:
1577 - added aRts audio output driver (by no means RT safe)
1578
1579 * MIDI driver:
1580 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1581 messages several times instead of once
1582 - API extension for MIDI drivers which already supply exact time stamps
1583 for events (i.e. for offline rendering based MIDI drivers)
1584 - added checks for bad MIDI data
1585
1586 * linuxsampler application:
1587 - show available sampler engine types on startup
1588
1589 * 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 (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 - support for sostenuto pedal
1598 - support for monitoring the total number of active voices
1599 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1600 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1601 - fixed some memory management errors
1602 - fixed some concurrency problems that could lead to crashes when
1603 LSCP commands were executed
1604 - fixed crash when instrument loading failed previously on the same
1605 sampler channel (fixes bug #36)
1606
1607 Version 0.3.3 (15 July 2005)
1608
1609 * packaging changes:
1610 - fixed compilation with gcc 4.0
1611
1612 * Gigasampler format engine:
1613 - LFO preprocessing was performed even though the respective LFO was
1614 disabled by the instrument patch (minor efficiency fix)
1615 - 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
1621 Version 0.3.2 (24 June 2005)
1622
1623 * packaging changes:
1624 - updated autotools build files to compile on OS X
1625 (conditional compilation of CoreMIDI and MidiShare drivers)
1626 - hand-crafted assembly optimization code can be disabled with
1627 './configure --disable-asm' (definitely not recommended)
1628 - 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
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 - revised voice stealing
1639 (fixes crash and endless loop caused by voice stealing)
1640 - don't reset scale tuning on instrument or audio output device change
1641 - 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 - 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 - don't reset volume, pan, pitch and MIDI controller values on
1649 instrument or audio output device change
1650
1651 * LSCP server:
1652 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1653 - fixed LSCP event "CHANNEL_INFO" notification
1654 (e.g. did not notify on volume changes or MIDI program change events)
1655
1656 * 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 Version 0.3.1 (24 May 2005)
1661
1662 * initial release
