File size: 93500 byte(s)
Refactored LFO class names and their header file names:

* Renamed PulseLFO -> LFOPulse, LFOSawIntMath -> LFOSawIntMathNew,
  SawLFO -> LFOSawIntMathOld, SineLFO -> LFOSineBuiltinFn,
  LFOSine -> LFOSineNumericComplexNr, SquareLFO -> LFOSquarePulse.

* Separated LFOSquarePulse (previously "SquareLFO") to its own
  header file.

* Renamed type LFOSigned -> LFOTriangleSigned.

* Renamed type LFOUnsigned -> LFOTriangleUnsigned.

* Bumped version (2.1.1.svn19).

1 Version SVN trunk (?)

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

463 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
464 intuitive behavior if used in combination with "change_vol_time()" or
465 "change_tune_time()" respectively: now tuning/volume changes are only
466 assigned (without delay) immediately to a new note if the respective
467 timing function has not been called before, otherwise the volume/tuning

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

513 - Added built-in constant $CALLBACK_STATUS_RUNNING.
514 - Removed max. value limitation of built-in functions "change_attack()",
515 "change_decay()" and "change_release()" to i.e. allow passing 2000000
516 for doubling the respective time.
517 - NKSP script editor syntax highlighting API: Fixed app termination due
518 to a lexer start condition stack underrun.
519 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
520 USE_CODE_IF_NOT() preprocessor statements.

584 in order to get rid of warnings from automake 1.14
585
586 * general changes:
587 - Refactoring: moved the independent code from
588 the Gigasampler format engine to base classes
589 - command line option '--profile' is currently disabled, since the
590 respective profiling code is currently broken
591 - Introduced support for optional environment variable
592 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
593 where the sampler shall look for instrument editor plugins
594 (patch by Luis Garrido, slightly modified).
595 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
596 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
597 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
598 note (in this implementation of the sampler its simply hard routed to
599 the 1st effect send of the sampler channel, no matter what the actual
600 effect type is)
601 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
602 note (in this implementation of the sampler its simply hard routed to
603 the 2nd effect send of the sampler channel, no matter what the actual
604 effect type is)
605 - implemented support for internal LADSPA effects
606 - raised limit of program change queue from 100 to 512
607 (as suggested by Alex Stone)
608 - implemented sine LFO, pulse LFO and saw LFO
609 - experimental support for per voice equalization
610 - added command line option --exec-after-init
611 - Introduced new C++ API method:
612 EngineChannel::InstrumentFileName(int index)
613 allowing to retrieve the whole list of files used for the loaded
614 instrument on an engine channel (a.k.a. part). Some GigaStudio
615 instruments for example are splitted over several files like
616 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
617 - Added new C++ API method Sampler::GetGlobalMaxVoices().
618 - Added new C++ API method Sampler::GetGlobalMaxStreams().
619 - Added new C++ API method Sampler::SetGlobalMaxVoices().
620 - Added new C++ API method Sampler::SetGlobalMaxStreams().
621 - Various "const" and "restrict" optimizations.
622 - all engines: add pan CC value to instrument pan parameter before
623 applying panning, instead of using two separate pan functions in
624 series (#182)
625 - added a lock guard class for exception safe mutex handling and
626 used it everywhere appropriate
627 - Immediately apply scale tuning changes to active voices.
628 - Exposed scale tuning to C++ API (along to the already existing standard
629 SysEx way).
630 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
631 and broken for ppc64. (Seq_cst loads and stores are actually not
632 used in LS, so the bug wasn't noticable.)
633 - lsatomic.h: added ARMv7 support
634 - Added support for multiple MIDI input ports per sampler channel (and
635 added various new C++ methods for this new feature / design change, old
636 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
637 as deprecated but are still there and should provide full behavior
638 backward compatibility).
639 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
640 unsafe and caused compilation error with clang 2.x).
641 - Bugfix: only process the latest MIDI program change event.
642 - Introducing the LSCP shell, which provides convenient control of the
643 sampler from the command line by providing LSCP aware features.
644 - VirtualMidiDevice: Added support for program change.
645 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
646 - VirtualMidiDevice: Added support for pitch bend.
647 - Aftertouch: extended API to explicitly handle channel pressure and
648 polyphonic key pressure events (so far polyphonic pressure was not
649 supported at all, and channel pressure was rerouted as CC128 but not
650 used so far).
651 - Added initial support for real-time instrument scripts. The script VM
652 code is shared by all sampler engine implemementations, however only the
653 gig file format currently provides support for storing instrument scripts
654 (as LinuxSampler extension to the original GigaStudio 4 format).
655
656 * Gigasampler format engine:
657 - implemented the "round robin keyboard" dimension

661 key
662 - bugfix: pitch LFO controller "internal+aftertouch" was broken
663 - bugfix: filter keyboard tracking was broken
664 - filter performance fix (an unnecessary copy was made of the
665 filter parameters in each sub fragment)
666 - handle special case when pan parameter in gig file has max or
667 min value
668 - Exclusive Groups: don't ever stop voices of the same note,
669 doesn't sound naturally with a drumkit
670 - fixed EG1 modulation when attack or release is zero
671 - Fixed support for 'aftertouch' attenuation controller.
672 - Fixed crash that happened with velocity split sounds under certain
673 conditions (see also previous commit on libgig).
674 - fixed behaviour of filter LFO
675
676 * SFZ format engine:

706 - added support for loop_mode=one_shot
707 - fixed playback of 16 bit wav files on big endian CPUs
708 - added support for Ogg Vorbis sample files
709 - use loop markers from sample file if loop_start and loop_end are
710 not set in sfz file
711 - implemeted filters. Filter types: lowpass, bandpass, bandreject
712 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
713 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
714 cutoff_cc, cutoff_chanaft.
715 - bugfix: zero ampeg_sustain didn't work

851 - AU bugfix: failed to destroy its audio/MIDI devices
852 - Listen to all interfaces on Mac OS X (INADDR_ANY)
853 - VST bugfix: If the host called resume() before and after
854 changing sample rate or block size, the number of channels was
855 incorrectly set to two. This caused silence in Cubase 5.
856 - save engine type (gig, sfz or sf2) in plugin state
857 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
858 64 bit Windows

868 loaded a second time (this time it's for Linux and Mac, previous
869 similar fix was for Windows)
870 - thread safety fixes for the instrument loading thread

875 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
876 port and audio channel routing for DSSI plugins are now visible.
877 - LV2: use urid and atom extensions instead of deprecated uri-map
878 and event
879 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

890 spawned for. This allows the instrument editors to interact more actively
891 with the sampler.
892
893 * MIDI driver:
894 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
895 the ALSA sequencer client name

901 which allows to retrieve the list of CoreMIDI clients / ports and to connect
902 to them a la JACK, via the usual sampler APIs
903 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
904 the driver will automatically connect to other CoreMIDI clients' ports
905 (e.g. external MIDI devices being attached to the Mac)
906 - added support for MIDI note on velocity filter
907 - CoreMIDI: fixed memory deallocation error
908 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
909 virtual keyboards in frontends / instrument editors being stuck.
910 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
911 - Implemented missing handling of MIDI "running status".
912 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
913 - MME bugfix: driver wasn't closed properly

979 - Added support for moving cursor left/right with arrow keys.
980 - Added support for built-in LSCP reference documentation, which will
981 automatically show the relevant LSCP reference section on screen as soon

1029 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1030 (i.e. return value of new script function "by_marks()").
1031 - Pass/preserve polyphonic variable data from respective "note" event
1032 handler to "release" event handler.

1039 channel to a different engine type
1040 - fixed crash when deleting a sampler channel or changing engine
1041 type while an instrument load was in progress
1042 - bugfix: playing a note while changing the instrument could cause
1043 a crash, or give "Handing back unknown region" error messages
1044 - bugfix: calling SET VOICES (which Fantasia does on start and
1045 refresh) could cause instruments to be unloaded
1046 - Mac OS X: fixed name collision of enum in EffectControl and
1047 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1048 - Mac OS X: fixed hanging threads
1049 - Windows: disabled the previous thread fix on non-Mac systems, as
1050 it caused hanging threads on Windows
1051 - Fixed possible crashes due to corrupted MIDI/audio device list
1052 after MIDI/audio device creation failure
1053 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1054 instruments were uselessly precached with zero samples, however it still
1055 took the full preloading time and on 1st program change the respective
1056 instrument was completely reloaded again.
1057 - fixed handling of rapid bank select and program change messages
1058 sent to the same sampler channel (patch from the Open Octave
1059 project, slightly adjusted)
1060 - fixed crash when trying to create an effect instance with controls
1061 which min and/or max values depend on the sample rate

1074 playing a note in a key group
1075 - fixed erroneous error message piping in VoiceBase.h
1076 (labelled "Disk stream not available in time")
1077 - Update effects on sample rate & period size changes (to avoid
1078 crashes and noise on such transitions).
1079 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1080 (fixes #208)
1081 - Fixed bug in LSCP grammar definition which caused a statement like
1082 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1083 practically irrelevant, however it caused problems with the new LSCP
1084 shell's auto completion feature).
1085 - Fixed MIDI program change messages being ignored if quickly executed
1086 after each other (fixes #231).
1087
1088 Version 1.0.0 (31 July 2009)
1089
1090 * packaging changes:
1091 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1092 causing e.g. the libgig test to fail when
1093 "./configure --disable-jack-driver" was used
1094 (patch by Alexis Ballier)
1095 - fixed compilation with gcc 4.3
1096 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1101 - minor fix in configure for mmsystem.h detection on MinGW
1102 - Windows: look for editor plugins and Fantasia using base
1103 directory of liblinuxsampler dll (look in the same directory and one
1104 directory above)
1105 - configure script fix: removed unconditional use of SSE
1106 - fixed building with sqlite installed in a non-standard directory
1107 - when cross-compiling, don't try to create instruments.db
1108 - fix for new mingw-w64 version, which has usleep
1109
1110 * general changes:
1111 - bugfix: on some POSIX systems instrument editor plugins refused to
1112 load as we used a non-portable Linux specific struct field
1113 (fixes bug #70, patch by Ronald Baljeu)
1114 - fixed endless loop which occured when loading an instrument editor
1115 plugin DLL on Windows systems failed
1116 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1117 - optimized the SynchronizedConfig class so it doesn't wait
1118 unnecessarily long after an update
1119 - added support for notifying instrument editors on note-on / note-off
1120 events (e.g. to highlight the pressed keys on the virtual keyboard
1121 of gigedit)
1122 - added support for triggering notes by instrument editors (see above)
1123 - be verbose on DLL load errors (on Linux)
1124 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1125 is only used by very few systems, most pick the int math
1126 implementation, which is usually faster)
1127 - fixes for audio drivers with varying buffer sizes
1128 - experimental support for running LinuxSampler as a DSSI, LV2 and
1129 VST plugin
1130 - notification events for stream/voice count statistics are now sent
1131 only when there are actual changes
1132 - added memory ordering constraints to improve stability on
1133 multi-core and multi-cpu systems
1134 - maximum voices and disk streams can now be altered at runtime
1135 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1136 - automatic stacktrace mechanism is now turned off by default and can
1137 be switched on by command line option "--stacktrace" (the automatic
1138 stacktrace mechanism seems to be broken on most systems at the moment)
1139 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1140 a pointer to the launched InstrumentEditor object
1141 - added optional 3rd party user data parameter for following
1142 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1143 InstrumentEditor::Launch(),
1144 InstrumentManager::LaunchInstrumentEditor()
1145 - theoretical fix: made SynchronizedConfig follow C++0x memory
1146 model more strictly
1147 - fixes for using large audio device buffers
1148 - Windows: add the installation directory to the DLL search path
1149 when loading an editor plugin (solves problems with VST and
1150 gigedit on systems with other GTK versions installed)
1151 - updated linuxsampler man page
1152
1153 * audio driver:
1154 - removed the nonsense audio channel constraint (which was hard coded to
1155 max. 100 audio channels) for most audio drivers
1156 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1157 opposed to the LSCP specs
1158 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1159 reflected the wrong value
1160 - fixed a memory management bug in ASIO driver
1161 - Makefile fix: JACK_CFLAGS wasn't used
1162 - JACK: use jack_client_open instead of the deprecated
1163 jack_client_new
1164 - added (experimental) CoreAudio driver
1165 - applied old fixes to the ASIO driver that were included in the
1166 previous binary release but accidentally never committed to CVS
1167 (fixes #117)
1168 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1169 win64)
1170 - VST: added support for sample rate and buffer size changes
1171 - VST: close editor (Fantasia) when the VST is removed
1172 - VST: avoid opening Fantasia more than once for each VST instance
1173 - VST: export main function as "main" on Linux too (fix for
1174 energyXT)
1175 - VST: changed number of output channels from one stereo to 16
1176 stereo
1177 - added channel routing, fxsends and midi maps to the settings
1178 stored in the plugin state
1179 - performance optimization of AudioChannel::MixTo() and
1180 AudioChannel::CopyTo() methods using GCC vector exensions
1181 (if available)
1182 - ASIO fixes: avoid initializing the device twice, avoid throwing
1183 exception when getting parameters from a disconnected device
1184
1185 * MIDI driver:
1186 - added JACK MIDI driver
1187 - dispatch bank select as ordinary CC as well, the user might seriously
1188 want to (mis)use it for some purpose ("fixed" in all current MIDI
1189 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1190 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1191 CoreMidi or AU
1192 - fixed mingw-w64 compilation error in MME driver
1193 - made program change handling in MIDI thread real-time safe by
1194 moving the logic to a non-RT thread
1195 - fixed minor memory leak in ALSA driver
1196
1197 * instruments database:
1198 - avoid time consuming samples scanning when adding instruments
1199 to the instruments database
1200 - added support for handling lost files in the instruments database
1201 - Implemented option for adding instruments in separate directories
1202 in the instruments database
1203 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1204 - work-around for missing fnmatch function on Windows to make
1205 instrument database compilable
1206 - added instrument database support on Windows
1207 works with both standalone mode and VST plugin.
1208 the instruments DB file is located in
1209 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1210 databases for each windows user
1211 if no DB is present it automatically creates the .linuxsampler subdir
1212 and then creates an empty DB
1213 - fixed recursive import, which was broken on Windows
1214
1215 * Gigasampler format engine:
1216 - fixed a memory leak that could happen when a channel was deleted
1217 while notes were playing
1218 - made it possible to load an instrument even if the audio thread
1219 isn't running
1220 - added partial support for the "Controller Triggered" MIDI rule,
1221 enough for piano gigs with pedal noise samples
1222 - minor fix: only mark FX sends as being modified if really the
1223 respective FX send MIDI controller was used
1224 - added support for GM global device volume SysEx message
1225 (can be selected at compile time to either apply globally to the
1226 whole sampler [default] or only to the sampler channels that are
1227 connected to the respective MIDI input port the SysEx message arrived
1228 on)
1229 - bugfix: notes triggered at position 0 in the audio buffer were
1230 sometimes wrongly killed in the same buffer, causing no sound to
1231 be played
1232 - added support for chromatic / drumkit mode Roland GS Sysex message
1233 which is usally used to switch a part between chromatic sounds and
1234 drumkit sounds (as opposed to their common default setting of MIDI
1235 part 10 being a drumkit part and all other ones chromatic parts), in
1236 LS however one can switch between the first 16 MIDI instrument maps
1237 defined for the sampler
1238 - made it possible to create multiple sample channels even if the
1239 audio thread isn't running
1240 - fixed crash when removing channel with active voices (#116)
1241 - bugfix: on sample reference changes (instrument editor), only
1242 un-cache the respective sample if it's really not used by any
1243 sampler engine anymore
1244 - re-cache samples in case they were changed by an instrument editor,
1245 e.g. when a sample was added while playing (#82)
1246 - fixed hanging notes which occured when note-off event had the exact
1247 same time stamp as the voice's note-on event and occured both in the
1248 same audio fragment cycle (fixes bug #112)
1249 - added support for the "fine tune" and "pitch bend range"
1250 instrument-level gig parameters
1251 - fixed minor artifacts in pitch bend handling
1252 - added support for GS Reset SysEx message
1253 - allow gig files to use unlimited downward pitch shifting
1254 - added a limit check for upward pitch shifting
1255 - bugfix: sometimes, when playing a note twice fast, the second
1256 note was silent
1257 - fixed crash happening when a pitch bend event arrived at the
1258 same time a new instrument was loading
1259
1260 * LSCP server:
1261 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1262 react on MIDI data arriving on certain sampler channels (so far only
1263 Note-On and Note-Off events are sent via this LSCP event)
1264 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1265 react on MIDI data arriving on certain MIDI input devices (so far only
1266 Note-On and Note-Off events are sent via this LSCP event)
1267 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1268 SET DB_INSTRUMENT FILE_PATH
1269 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1270 frontends to send MIDI messages to specific sampler channel
1271 - added two additional fields to GET FILE INSTRUMENT INFO command -
1272 KEY_BINDINGS and KEYSWITCH_BINDINGS
1273 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1274 was incorrect
1275 - Optimized the retrieval of the MIDI instrument mappings
1276 - added new LSCP command "SET VOICES" to globally alter the maximum
1277 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1278 be triggered respectively
1279 - added new LSCP command "SET STREAMS" to globally alter the maximum
1280 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1281 which will be triggered respectively
1282 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1283 a gigedit file dialog is opened)
1284 - close all connections when LSCPServer is deleted
1285 - hard close of all sockets on exit
1286 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1287 driver
1288
1289 * Bug fixes:
1290 - fixed a crash which occurs when removing a sampler channel waiting
1291 to start instrument loading after another channel
1292 - fixed a crash which occurs when removing a sampler channel with
1293 instrument loading in progress (bug #113)
1294 - fixed termination caused by uncaught exception when adding MIDI
1295 instrument with PERSISTENT load mode
1296 - fixed possible iterator invalidations when resetting the sampler
1297 - fixed memory leaks when issuing the following LSCP commands:
1298 GET AUDIO_OUTPUT_DRIVER INFO
1299 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1300 GET MIDI_INPUT_DRIVER INFO
1301 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1302 - fixed possible compilation error when sqlite is not present
1303 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1304 - fixed crash when changing the audio output device of a sampler
1305 channel with loaded instrument and start playing notes
1306 - fixed endless loop in Engine::SuspendAll() (bug #120)
1307 - fixed a low-level atomic load function that was broken on 64-bit
1308 PowerPC, which probably could cause crashes on that platform
1309 - fixed a memory management error which could cause a crash when a
1310 plugin was unloaded
1311 - bugfix: two private structs had the same name, which could cause
1312 problems if the linker chose the wrong constructor
1313 - fixed low-level ConditionServer usage bug that caused lockups on
1314 Windows
1315
1316
1317 Version 0.5.1 (6 December 2007)
1318
1319 * packaging changes:
1320 - added autoconf checks for pthread library
1321 - added autoconf check for pthread bug found on certain NPTL-enabled
1322 glibc versions (see Gentoo bug report #194076)
1323 - added autoconf checks for MS Windows
1324
1325 * general changes:
1326 - bugfix: the thread used by an editor plugin didn't die when the
1327 editor closed
1328 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1329 out all the space. operator--() did not apply size_mask after
1330 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1331 order to avoid problems with the _NonVolatileReader functions.
1332 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1333 GetWriteSpace(). Since this function is currently only used in
1334 the stream's qsort() compare function, it didn't trigger any
1335 bugs.
1336 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1337 24bit mode too. Faster method to read 24bit words on little
1338 endian machines (x86): replaced 3 byte reads + shifts with a 1
1339 unaligned 32bit read and shift
1340 - experimental support for MS Windows (MIDI input via MME, AUDIO
1341 output via ASIO)
1342 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1343 - support for monitoring the total number of active disk streams
1344 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1345 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1346
1347 * AUDIO driver:
1348 - added Windows ASIO low latency audio driver
1349
1350 * MIDI driver:
1351 - added MME Windows MIDI driver
1352
1353 * LSCP server:
1354 - added support for Windows style path / filenames, however with
1355 forward slash path separators instead of backslash
1356 (i.e. "C:/foo/bar.gig")
1357 - allow naughty liblscp to send non-string device parameters within
1358 apostrophes as well
1359 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1360 "LIST FILE INSTRUMENTS <file>" and
1361 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1362 about an arbitrary instrument file on the system where the sampler is
1363 running on
1364
1365 Version 0.5.0 (15 October 2007)
1366
1367 * packaging changes:
1368 - config.h is not going to be installed along with liblinuxsampler's
1369 API header files anymore
1370 - only the API relevant header (and source) files will be exported to
1371 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1372 - added completely new XCode project files for Mac OSX which is now
1373 capable to execute our autoconf environment, thus no need anymore
1374 to maintain the compile time configuration file (osx/version.h) for
1375 OSX manually (patch by Toshi Nagata)
1376 - fixed buggy boolean --enable-foo / --disable-foo configure script
1377 parameters
1378 - global.h now only covers global definitions that are needed for the
1379 C++ API header files, all implementation internal global definitions
1380 are now in global_private.h
1381 - atomic.h is not exposed to the C++ API anymore
1382 - no need to include config.h anymore for using LS's API header files
1383 - fixed warnings in API doc generation
1384
1385 * general changes:
1386 - replaced the old, confusing MIDI program change mechanism by a
1387 flexible MIDI instrument mapper which allows to map arbitrary
1388 (MIDI bank, MIDI program) pairs with arbitrary
1389 (engine type, instrument file, file index) triplets which will be
1390 loaded on the respective channel when such MIDI program change
1391 messages arrive, beside that, each entry allows to define a life-time
1392 strategy for the instrument, so the user can define whether the
1393 instrument should i.e. be permanently loaded (to be able to switch
1394 quickly among sounds) or i.e. loaded just on demand when the
1395 respective program change arrives (to safe RAM space), as well as a
1396 global volume factor for each entry, so the user can adjust the volume
1397 dynamic of his mapped instrument collection without having to modify
1398 the instrument files, also one can manage arbitrary amount of such
1399 MIDI instrument maps and assign each sampler channel individually
1400 a certain map, so that i.e. separation of normal instruments and
1401 drumkits is possible
1402 - new notification events for tracking changes to audio/MIDI devices,
1403 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1404 - sampler was limited to load max. 200 instruments in the background
1405 due to a constant size RingBuffer FIFO which is now replaced by a
1406 dynamic (unlimited) size std::list FIFO
1407 - added FX sends, these allow to route audio signals to arbitrary audio
1408 output channels for being processed by external effect processors
1409 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1410 controllers
1411 - global (sampler wide) volume can now be controlled at runtime
1412 - Implemented new, improved notification system
1413 - fixed compilation errors regarding OSX
1414 (patch by Toshi Nagata)
1415 - implemented instruments database
1416 - added support for escape sequences to the instruments database
1417 - added highly experimental support for on-the-fly instrument editing
1418 within the sampler's process (by using instrument editor plugins),
1419 you'll notice the new "Registered instrument editors:" message on
1420 startup, added a new LSCP command:
1421 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1422 to spawn a matching instrument editor for the instrument on the
1423 given sampler channel, the plugin path can be overridden at compile
1424 time with ./configure --enable-plugin-dir=/some/dir
1425 - added experimental code for synchronizing instrument editors hosted
1426 in the sampler's process to safely edit instruments while playing
1427 without a crash (hopefully) by either suspending single regions
1428 wherever possible or if unavoidable whole engine(s)
1429 - fixed several issues in fundamental "Thread" class: set scheduling
1430 policy and priority on thread level, set a minimum stack size for
1431 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1432 threads simply inherited properties of starting thread instead of
1433 setting their own policy and priority
1434 - minor fix in our automatic stack trace mechanism on crashes, the
1435 main process did not wait for the stack trace process to finish
1436 its output
1437 - fixed some minor memory leaks
1438 - reenabled assembly features support, at the moment only for
1439 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1440 - minor assembly fix in x86 features detection (don't use the PIC
1441 register, to avoid relocations in the text segment at runtime)
1442 - POSIX callback functions of Thread.h are hidden
1443
1444 * MIDI driver:
1445 - dispatch bank select (MSB and LSB) messages
1446
1447 * audio driver:
1448 - the ALSA audio output driver parameters now reflect the correct
1449 parameter value ranges for the respective selected sound card
1450 (patch by Till Wimmer, a bit fixed and extended)
1451
1452 * Gigasampler format engine:
1453 - if a filter is used and EG2 finishes before EG1, let the voice
1454 die when EG2 has finished (this fixes a problem with clicks and
1455 voice starvation for some gigs)
1456 - playback is no longer disabled during instrument loading
1457 - all notes playing on a channel that changes its instrument keep
1458 playing with the old instrument until they get a note off
1459 command
1460 - EG fix: a release value of zero could cause noises or crash
1461 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1462 - EG fine tuning: when attack is zero the EG starts at a level
1463 above max sustain level, which means that there is a decay phase
1464 even if sustain is 100%
1465 - more EG fixes: the level could sometimes go below zero and cause
1466 noises or crashes
1467 - minor fix of EGDecay (patch by Toshi Nagata)
1468 - fixed compiler error when --enable-override-filter-type was
1469 supplied to the configure script (fixes #46)
1470 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1471 instead of a fix value
1472 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1473 127 (solo mode) only kill voices if the respective mode really
1474 changed
1475
1476 * LSCP server:
1477 - fixed compile time error for old Bison versions
1478 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1479 - parser now supports extended ASCII character set
1480 (up to ASCII code 255, i.e. includes now umlauts and accents)
1481 - filename arguments in LSCP commands now allow to use escape
1482 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1483 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1484 code value like \xf2) (fixes bug #24)
1485 - the following LSCP commands now also support escape sequences for at
1486 least one of their text-based parameters (i.e. name, description):
1487 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1488 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1489 "SET DB_INSTRUMENT_DIRECTORY NAME",
1490 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1491 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1492 "FIND DB_INSTRUMENT_DIRECTORIES"
1493 - returns verbose syntax errors (line and column where syntax error
1494 occured, the unexpected character and the actually expected, possible
1495 character(s), the latter only if less than 5 possibilities)
1496 - made sure that LSCP syntax is not affected by gigedit locale
1497 settings
1498 - bugfix regarding strings parameter lists: all comma separated lists
1499 of strings were treated as being one string containing commas
1500 (fixes #57)
1501
1502 * Bug fixes:
1503 - fixed crash occurring on certain LSCP scripts (Bug 39)
1504 - another thread safety fix for lscp "load engine" and "set
1505 channel audio output device"
1506 - fixed a crash which occurs when reassigning the same engine
1507 on a sampler channel with connected MIDI device
1508 - fixed a crash which occurs when changing the number of ports of a MIDI
1509 device connected to a sampler channel to number less then or equal
1510 to the index of the port to which the sampler channel is connected.
1511 - The previous bindings were not been disconnected when altering
1512 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1513 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1514 - The active stream/voice count statistic was incorrect.
1515 - notification events were not been sent for some sampler
1516 channel changes
1517 - added default min and max values to restrict the number of allowed
1518 audio output channels and MIDI input ports
1519 - the connection to the PCM interface is now closed when destroying
1520 an audio output device
1521 - files with slash in their path or filename could not be loaded
1522
1523 * test cases:
1524 - updated and fixed (haven't been touched in a while)
1525
1526 Version 0.4.0 (24 November 2006)
1527
1528 * packaging changes:
1529 - changed deprecated copyright attribute to license; added ldconfig
1530 to post-(un)install steps; added devel package for liblinuxsampler;
1531 to linuxsampler.spec (RPM)
1532 - install necessary development header files for allowing 3rd party
1533 applications to link against liblinuxsampler
1534 - liblinuxsampler's API documentation can be generated with 'make docs'
1535 (Doxygen required)
1536 - added benchmark to automatically detect the best triangle LFO
1537 implementation (currently either an integer math solution or a
1538 di-harmonic approximation), automatic detection can be overriden
1539 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1540 configure script argument though (mandatory for cross-compilation)
1541 - do not automatically pick optimized gcc flags if the user already
1542 provided some on his own (as CXXFLAGS)
1543 - added compile time option to disable processing of All-Notes-Off MIDI
1544 messages
1545 - added compile time options to allow disabling the various audio and
1546 MIDI drivers
1547 - fixed automatic GCC CPU switch detection on PPC
1548 (patch by Ebrahim Mayat)
1549
1550 * Gigasampler format engine:
1551 - extensive synthesis optimization
1552 (reimplementation of EGs and LFO(s), removed synthesis parameter
1553 prerendering and the synthesis parameter matrix in general, splitting
1554 each audio fragment into subfragments now where each subfragment uses
1555 constant pitch and filter coefficients. The volume coefficient is
1556 linearly interpolated inside a subfragment, unless
1557 --disable-interpolate-volume is set.)
1558 - fine tuning of the EG modulation parameters
1559 - improved filter cutoff calculation by adding support for the
1560 following gig parameters: Cutoff freq (used when no cutoff
1561 controller is defined), Control invert, Minimum cutoff, Velocity
1562 curve and Velocity range. The keyboard tracking now scales
1563 cutoff frequency instead of resonance.
1564 - added support for gig parameter Resonance.
1565 - fixed bug in sysex handling (patch by Juan Linietsky)
1566 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1567 which can be overridden with --enable-global-attenuation
1568 - EG fixes: made the length of "attack hold" stage more
1569 accurate. Release stage can now start before attack stage
1570 ends. Cancel release didn't work when sustain was zero. Attack
1571 time now has a minimal value to prevent clicks.
1572 - fixed pitch changes larger than one octave
1573 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1574 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1575 all modes can be altered via standard GM messages, that is CC5 for
1576 altering portamento time, CC65 for enabling / disabling portamento
1577 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1578 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1579 parameter) and crossfade
1580 - added support for the "attenuation controller threshold" gig
1581 parameter
1582 - added smoothing of volume changes caused by control change
1583 messages
1584 - sample loop parameters are now taken from the DimensionRegion
1585 instead of the wave chunk
1586 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1587 not equal to a power of two
1588 - reimplementation of the filter algorithm. The new filter is more
1589 accurate and supports all gig filter types, including bandreject
1590 and lowpass turbo.
1591 - real support for 24 bit samples - samples are not truncated to
1592 16 bits anymore
1593 - support for aftertouch (channel pressure, not polyphonic
1594 aftertouch)
1595 - LFO1 behaviour fixed (dampening from max volume instead of
1596 amplifying from 0)
1597
1598 * LSCP server:
1599 - fixed application exit on broken pipe error (fixes bug #20)
1600 - fixed the notification messages delay due to lack of
1601 network activity (fixes bug #26)
1602 - fixed parser bug which occured on space(s) within device parameters
1603 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1604
1605 * audio driver:
1606 - added aRts audio output driver (by no means RT safe)
1607
1608 * MIDI driver:
1609 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1610 messages several times instead of once
1611 - API extension for MIDI drivers which already supply exact time stamps
1612 for events (i.e. for offline rendering based MIDI drivers)
1613 - added checks for bad MIDI data
1614
1615 * linuxsampler application:
1616 - show available sampler engine types on startup
1617
1618 * general changes:
1619 - support for muting sampler channels and solo mode of the same, two new
1620 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1621 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1622 introduced for this, the behavior is the same like on a mixer console
1623 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1624 --enable-process-muted-channels which can be used to enable the
1625 processing of muted channels.
1626 - support for sostenuto pedal
1627 - support for monitoring the total number of active voices
1628 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1629 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1630 - fixed some memory management errors
1631 - fixed some concurrency problems that could lead to crashes when
1632 LSCP commands were executed
1633 - fixed crash when instrument loading failed previously on the same
1634 sampler channel (fixes bug #36)
1635
1636 Version 0.3.3 (15 July 2005)
1637
1638 * packaging changes:
1639 - fixed compilation with gcc 4.0
1640
1641 * Gigasampler format engine:
1642 - LFO preprocessing was performed even though the respective LFO was
1643 disabled by the instrument patch (minor efficiency fix)
1644 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1645 for volume ramp downs in the same fragment (needed for current voice
1646 stealing implementation) then simply inform the user with a warning
1647 about possible click sounds and reduce the volume ramp down
1648 appropriately instead of cancelling the audio device connection
1649
1650 Version 0.3.2 (24 June 2005)
1651
1652 * packaging changes:
1653 - updated autotools build files to compile on OS X
1654 (conditional compilation of CoreMIDI and MidiShare drivers)
1655 - hand-crafted assembly optimization code can be disabled with
1656 './configure --disable-asm' (definitely not recommended)
1657 - fixed 'make dist' rule to include all necessary files
1658 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1659 (due to 'dist-bzip2' automake option)
1660
1661 * Gigasampler format engine:
1662 - support for the gig parameters for "release velocity response" curves
1663 - fine tuning of the EGADSR envelope
1664 - volume of release triggered samples now depends on note-on velocity,
1665 note length and gig parameter "release trigger decay" instead of
1666 note-off velocity.
1667 - revised voice stealing
1668 (fixes crash and endless loop caused by voice stealing)
1669 - don't reset scale tuning on instrument or audio output device change
1670 - handle key group conflicts right at the beginning of each fragment
1671 instead of when the respective voice is actually launched
1672 (fixes undefined behavior if stolen voices belonged to a key group -
1673 this case was followed by a "killed voice survived" error message)
1674 - fixed minor issue with null/silence samples
1675 (those stole voices even though they don't need a voice at all which
1676 resulted in "voice stealing didn't work out" messages)
1677 - don't reset volume, pan, pitch and MIDI controller values on
1678 instrument or audio output device change
1679
1680 * LSCP server:
1681 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1682 - fixed LSCP event "CHANNEL_INFO" notification
1683 (e.g. did not notify on volume changes or MIDI program change events)
1684
1685 * linuxsampler application:
1686 - added command line parameters --lscp-addr and --lscp-port to override
1687 default IP address and port of LSCP server
1688
1689 Version 0.3.1 (24 May 2005)
1690
1691 * initial release
