* Fixed playing noise at the end of a disk stream under certain
  conditions.

* Bumped version (2.1.1.svn42).

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 - 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 - Using now cubic interpolation as resampling algorithm by default; and
30 linear interpolation is deprecated now.
31 - Event:Init(): memset() entire Event::Param union to zero instead of trying
32 to do that for its individual members; the latter became error prone due
33 to the union's growing complexity meanwhile.
34 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36 methods and marked the old ones as deprecated; and likewise added new
37 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38 methods and marked those old ones deprecated as well.
39 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41 - Implemented support for compressed RPN/NRPN message sequences (that is to
42 allow processing MIDI data entry messages without always having to be
43 preceded strictly by RPN/NRPN parameter selection messages on each value
44 change).
45 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46 decrement).
47 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48 MSB=127 and LSB=127) and which is disabling subsequent data
49 entry/increment/decrement CC messages.
50 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51 instrument editor.
52 - Fixed playing noise at the end of a disk stream under certain conditions.
53
54 * Real-time instrument scripts:
55 - Added method ScriptVM::setExitResultEnabled() which allows to
56 explicitly enable the built-in exit() function to optionally accept
57 one function argument; the value of the passed exit() function
58 argument will then become available by calling
59 VMExecContext::exitResult() after script execution.
60 - 64 bit support for NKSP integer scripts variables (declare $foo).
61 - Variable names, function names and preprocessor condition names must start
62 with a regular character (a-z or A-Z); starting them with a digit or
63 underscore is not allowed.
64 - NKSP parser fix: equal comparison operator "=" and not equal comparison
65 operator "#" must only accept integer operands.
66 - NKSP language: Implemented support for standard units like Hertz, seconds,
67 Bel including support for metric unit prefixes; so one can now e.g.
68 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
69 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
70 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
71 - NKSP language: Introduced "final" operator "!" which is specifically
72 intended for synthesis parameter values to denote that the synthesis
73 parameter value is intended to be the "final" value for that synthesis
74 parameter that should explicitly be used by the engine and thus causing
75 the sampler engine to ignore all other modulation sources for the same
76 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
77 variable or formula with this new "!" operator the expression is marked as
78 being "final".
79 - NKSP script editor API: Added support for detecting standard unit tokens
80 and their potential metric prefix token.
81 - NKSP language: Added support for NKSP real number literals and
82 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
83 - NKSP language: Added support for NKSP real number (floating point) script
84 variables (declare ~foo).
85 - NKSP language: Added support for NKSP real number (floating point) array
86 script variables (declare ?foo[]).
87 - Built-in script function "message()" accepts now real number argument as
88 well.
89 - Added built-in script function "real_to_int()" and its short hand form
90 "int()" for casting from real number to integer in NKSP scripts.
91 - Added built-in script function "int_to_real()" and its short hand form
92 "real()" for casting from integer to real number in NKSP scripts.
93 - Allow built-in exit() function to potentially accept real number type
94 argument as well.
95 - Built-in script functions may have a different return type depending on
96 the arguments passed to the function.
97 - Built-in script function "abs()" optionally accepts and returns real
98 number.
99 - Built-in script functions "min()" and "max()" optionally accept real
100 number arguments and return real number as result in that case.
101 - NKSP VM API: Allow units and 'final'ness to be returned as result from
102 built-in functions (added methods VMFunction::returnUnitType() and
103 VMFunction::returnsFinal() for that purpose which must be implemented by
104 built-in function implementations).
105 - NKSP language: Allow metric unit prefixes of numeric scalar and array
106 variables to be changed freely at runtime (unlike unit types like Hz etc.
107 which are still sticky, parse-time features of variables which cannot be
108 changed at runtime for the intentional sake of determinism).
109 - NKSP language: 'final' values are prohibited for array variables for now
110 (attempt causes a parsers error).
111 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
112 conditions of runtime control structures like if(), while(), select()
113 (attempt causes a parser error).
114 - NKSP VM API: Allow built-in functions to perform their own, individual
115 parse time checks of arguments going to be passed to the function at
116 runtime (added method VMFunction::checkArgs() for that purpose).
117 - NKSP language: raise parser warning if only one operand of binary
118 operators (like logical 'or' comparison) contain a 'final' value (because
119 it would always yield in a 'final' result in such cases).
120 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
121 different metric unit prefixes, which will behave as expected (e.g.
122 result of expression '1000us < 2ms' is true).
123 - NKSP language: Allow adding values with different metric unit prefixes
124 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
125 - NKSP language: Allow subtracting values with different metric unit
126 prefixes (e.g. result of expression '1ms - 20us' is '980us').
127 - NKSP language: Allow multiplying with any metric unit prefixes
128 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
129 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
130 we don't have any considerable practical use for a term like '4s^2'
131 (hence any attempt multiplying two unit types still causes parser error).
132 - NKSP language: Allow dividing by any metric unit prefixes and allow
133 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
134 yields in unit free result '8'). So this is now a way to cast units away
135 e.g. for passing the result to other expressions, certain function calls
136 or variables which are not accepting any units (or that specific unit).
137 - NKSP language: integer arrays and real number arrays can now be converted
138 to strings (e.g. for dumping their content with message() calls for
139 script debugging purposes).
140 - NKSP language: expressions and variables with units are now correctly
141 casted to strings (e.g. with message() calls).
142 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
143 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
144 floating point tolerances into account.
145 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
146 VMScalarNumberExpr::evalCastReal().
147 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
148 'VMIntArrayExpr' and 'VMRealArrayExpr'.
149 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
150 unitFactor() (runtime) methods.
151 - Built-in function "exit()" supports now returning units and 'final'ness
152 for test cases.
153 - The following built-in functions support now units as well: "abs()",
154 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
155 "real_to_int()", "int()", "int_to_real()" and "real()".
156 - Built-in functions "array_equal()", "search()" and "sort()" support now
157 real number arrays (correctly) as well.
158 - Added individual parse time checks of arguments to be passed to built-in
159 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
160 "array_equal()" and "search()" specific for their individual purposes.
161 - NKSP VM refactoring: Renamed all methods, functions and classes matching
162 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
163 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
164 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
165 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
166 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
167 isScalarNumber() -> isNumber()).
168 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
169 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
170 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
171 as convenient methods for automatically converting values to expected
172 metric value basis.
173 - Built-in function "wait()" accepts now both integers and real numbers as
174 argument.
175 - NKSP VM API cleanup: Get rid of legacy method
176 VMFunction::argType(vmint iArg) which was already superseded by its new
177 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
178 - NKSP parser: if wrong argument type was passed to a built-in function and
179 that built-in function accepts more than one data type for the argument,
180 then show all supported data types as parser error message.
181 - Built-in function "play_note()" accepts now real numbers and seconds as
182 unit type as well for its 3rd and 4th function arguments.
183 - The following built-in functions accept now real numbers as well for their
184 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
185 "change_attack()", "change_decay()", "change_release()",
186 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
187 "change_cutoff_sustain()", "change_cutoff_release()",
188 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
189 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
190 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
191 - Fixed built-in function "change_play_pos()" not having accepted metric
192 prefixes at all.
193 - Fixed the following built-in functions having misinterpreted values given
194 with unit type (for their 2nd argument) as if they were relative values
195 (that is as if they were passed without a unit type): "change_attack()",
196 "change_decay()", "change_release()", "change_cutoff_attack()",
197 "change_cutoff_decay()", "change_cutoff_release()".
198 - Fixed the following built-in functions having applied completely wrong
199 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
200 respective EGs being their modulation sink assume uint data type with
201 value range 0..1000 instead of 0.0..1.0.
202 - Added individual parse-time checks of function arguments for the following
203 built-in functions: "play_note()", "note_off()", "set_event_mark()",
204 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
205 "change_decay()", "change_release()", "change_cutoff_attack()",
206 "change_cutoff_decay()", "change_cutoff_release()",
207 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
208 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
209 "change_pan_time()".
210 - Don't abort function call if unit type was used and at the same time
211 'final' operator was omitted for the primary value argument of the
212 following built-in functions: "change_cutoff()", "change_attack()",
213 "change_decay()", "change_release()", "change_cutoff_attack()",
214 "change_cutoff_decay()", "change_cutoff_release()",
215 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
216 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
217 "change_pan_time()", instead imply 'final'ness at runtime and raise an
218 appropriate parser warning at parse time.
219 - Added built-in real number functions "round()", "ceil()", "floor()",
220 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
221 "cos()", "tan()", "asin()", "acos()", "atan()".
222 - Added built-in script real number constant "~NI_MATH_PI".
223 - Added built-in script real number constant "~NI_MATH_E".
224 - NKSP language: Allow unary '+' operator.
225 - Added built-in script functions "msb()" and "lsb()".
226 - NKSP language: Added support for RPN event handler
227 ("on rpn ... end on" in instrument scripts).
228 - NKSP language: Added support for NRPN event handler
229 ("on nrpn ... end on" in instrument scripts).
230 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
231 may be read from the new RPN/NRPN script handlers to get the (N)RPN
232 parameter that had been changed and its new value.
233 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
234 which are identifying the new (N)RPN handlers as such at script runtime.
235 - Implemented built-in script function "set_rpn()".
236 - Implemented built-in script function "set_nrpn()".
237 - Fix: built-in functions returning an array type were broken and caused a
238 crash when the built-in function's (supposed to be array) result value was
239 used by the script VM.
240 - Removed upper value constraint for 2nd argument of built-in functions
241 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
242 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
243 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
244 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
245 the LFO frequency / resonance / cutoff frequency.
246
247 * test cases:
248 - Fixed compiler errors in test cases.
249 - Updated README for how to compile & run test cases.
250 - Updated test case
251 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
252 expected behaviour of the Mutex class implementation (recursive
253 mutex type).
254 - Added test cases for NKSP core language aspects and core built-in
255 functions.
256 - Fixed thread tests segfaulting on Linux.
257 - NKSP: Added real number test cases for built-in functions exit(),
258 int_to_real(), real(), real_to_int() and int(), as well as for the
259 plus, minus and negate language operators.
260 - Added massive amount of NKSP test cases for standard measuring units and
261 'final' operator usage cases.
262 - Added NKSP test cases for (floating point tolerance aware) real number
263 equalness / unequalness comparison.
264 - Added NKSP int array and real array tests for value assignment and
265 initialization of arrays.
266 - Added NKSP test cases for built-in functions "round()", "ceil()",
267 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
268 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
269 - Added NKSP test cases for unary '+' operator.
270 - Added NKSP test cases for core built-in variables.
271
272 * GigaStudio/Gigasampler format engine:
273 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
274 behaviour for start_level_mid.
275 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
276 level (see discussion "GigaStudio LFO compatibility" on mailing list
277 from 2019-09-26 for details).
278 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
279 see discussion "GigaStudio LFO compatibility" on mailing list from
280 2019-09-26 for details).
281 - Format extension: Added support for different LFO wave forms (currently
282 either sine [default], triangle, saw or square).
283 - Format extension: Added support for LFO phase displacement (0��..360��).
284 - Format extension: Added support for flipping LFO polarity on LFO 3
285 (in the original gig format this was only available for LFO 1 and LFO 2).
286 - Format extension: Support for additional filter types:
287 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
288 bandreject 2-pole.
289 - Fixd potential crash with polynomial interpolator and max. pitch.
290 - If minimum cutoff is defined, remap cutoff controller CC values to really
291 span the entire possible cutoff range (and avoiding a dead controller
292 zone).
293
294 * SFZ format engine:
295 - Fixed support for regions with loccN/hiccN conditions on more than one
296 MIDI controller.
297
298 * Benchmarks:
299 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
300 algorithm (since result of 2nd run was not accumulated).
301 - Added benchmark for saw wave (benchmarks/saw.cpp).
302 - Added benchmark for sine wave (benchmarks/sine.cpp).
303 - Added benchmark for square wave (benchmarks/square.cpp).
304 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
305 which are large enough on modern systems.
306
307 Version 2.1.1 (27 Jul 2019)
308
309 * Real-time instrument scripts:
310 - Fixed behavior of built-in NKSP functions change_sustain(),
311 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
312 and change_cutoff_release().
313
314 * general changes:
315 - Only play release trigger samples on sustain pedal up if this behaviour
316 was explicitly requested by the instrument (otherwise only on note-off).
317 - Fixed compiler warnings.
318 - Fixed compilation error when cross-compiling to Mac.
319 - FX Sends: Provide more useful error messages on routing problems
320 (see bug #169).
321 - LSCP doc: Be more clear describing the two distinct approaches
322 of using external vs. internal effects (see bug #169).
323 - "optional" class: Fixed comparison operators.
324
325 * Gigasampler/GigaStudio format engine:
326 - Format extension: If requested by instrument then don't play release
327 trigger sample on note-off events.
328
329 * SFZ format engine:
330 - Fixed memory leak when releasing samples
331 (fixes bug #307, patch by Jacek Roszkowski)
332 - Fixed potential crash when a sample is shared by more than one region
333 (fixes bug #308, patch by Jacek Roszkowski).
334 - Opcode 'sample': Added support for built-in sample '*silence'
335 (fixes bug #310, patch by Jacek Roszkowski).
336
337 Version 2.1.0 (25 Nov 2017)
338
339 * SFZ format engine:
340 - added support for <global>, <master> and #define (patch by Alby M)
341 - Removed code duplication in SFZ file loading code.
342 - Added support for sfz extension opcode 'script' which may be used to
343 load real-time instrument script file (NKSP script language).
344 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
345 - Fixed unintended volume fade-in of voices under certain conditions.
346 - sfz parser: allow missing space between header and opcode
347
348 * Gigasampler/GigaStudio format engine:
349 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
350 cutoff settings.
351 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
352 all if an up-pitch of more than 40 semi tones was requested (I don't
353 think there is any stock gig sound that requires this behavior to
354 resemble its original sound).
355 - Added support for controlling whether the individual EGADSR stages may
356 be aborted (as LinuxSampler extension to the original GigaStudio 4
357 format).
358
359 * general changes:
360 - fixed printf type errors (mostly in debug messages)
361 - use unique_ptr instead of auto_ptr when building with C++11
362 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
363 allowing to sort data efficiently in real-time safe manner.
364 - RTList class: added methods for moving/inserting elements to arbitrary
365 position within a list.
366 - RTList class: added method fromPtr() for creating an Iterator object from
367 a raw element pointer.
368 - Attempt to partly fix resetting engine channels vs. resetting engine, an
369 overall cleanup of the Reset*(), ConnectAudioDevice(),
370 DisconnectAudioDevice() API methods would still be desirable though,
371 because the current situation is still inconsistent and error prone.
372 - Active voices are now internally grouped to "Note" objects, instead of
373 being directly assigned to a keyboard key. This allows more fine graded
374 processing of voices, which is i.e. required for certain instrument
375 script features.
376 - Fix: Release trigger voices were not spawned on sustain pedal up
377 (CC #64) events.
378 - Fix: Release trigger voices can now also distinguish correctly between
379 note-off and sustain pedal up events.
380 - All engines: Increased ramp speed of volume smoother and pan smoother
381 (while slow rate of crossfade smoother is preserved) to allow quick
382 volume and pan changes by instrument scripts for instance.
383 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
384 properly and thus were ignored for certain uses.
385 - Added new C++ API method
386 VirtualMidiDevice::SendChannelPressureToSampler().
387 - windows, 32-bit: fixed potential crashes by making sure the stack in
388 sub threads is 16-byte aligned
389 - fixed numerous compiler warnings
390 - Fixed invalid (note-on) event ID being assigned to new Note objects.
391 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
392 fixes potential undefined behavior.
393 - Fixed Note object leak when triggering notes on keys which did not
394 have a valid sample mapped (fixes bug #252).
395 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
396 - linuxsampler binary fix: option --create-instruments-db ignored
397 subsequent optional argument due to glibc's implementation oddity
398 which expects a "=" sign, but no space between them.
399
400 * packaging changes:
401 - removed unnecessary dependency to libuuid
402 (originated by libgig's usage of it)
403 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
404 auto detect whether it (sh/c)ould output its messages in color.
405 - Debian: Fixed packaging error about invalid "Source-Version"
406 substitution variable.
407 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
408 - Debian: Added build dependency to libsqlite3-dev for building
409 linuxsampler with instruments DB support.
410
411 * Real-time instrument scripts:
412 - Implemented scheduler for delayed MIDI events and for suspended scripts.
413 - Built-in script function "wait()": implemented support for function's
414 "duration-us" argument, thus scripts using this function are now
415 correctly resumed after the requested amount of microseconds.
416 - Built-in script function "play_note()": implemented support for
417 function's "duration-us" argument, thus notes triggered with this
418 argument are now correctly released after the requested amount of
419 microseconds.
420 - Fix: script events were not cleared when engine channel was reset,
421 potentially causing undefined behavior.
422 - Fixed crash which happened when trying to reference an undeclared
423 variable.
424 - Built-in script function "play_note()": Added support for passing
425 special value -1 for "duration-us" argument, which will cause the
426 triggered note to be released once the original note was released.
427 - Instrument script classes now exported with the liblinuxsampler C++ API.
428 - Added new API method ScriptVM::syntaxHighlighting() which provides
429 a convenient syntax highlighting backend for external instrument
430 script editor applications.
431 - Added new C++ API class "ScriptVMFactory".
432 - Extended parser issues to provide not only first line and first
433 column, but also last line and last column of issue (thus marking
434 the precise span of the issue within the source code).

448 - NKSP language: Added support for bitwise operators ".or.", ".and."
449 and ".not.".
450 - NKSP language scanner: Fixed IDs matching to require at least one
451 character (i.e. when matching function names or variable names).
452 - NKSP language scanner: disabled unusued rules.
453 - Fixed behavior of play_note() and note_off() functions which must
454 be distinguished engine internally from "real" MIDI note on/off
455 events in order to avoid misbehaviors like hanging notes.

481 - Fixed all change_*() built-in script functions to apply their
482 synthesis parameter changes immediately in case the respective note
483 was triggered at the same time, instead of scheduling the parameter
484 change, especially because it would cause some parameter types's
485 changes either to be ramped (i.e. change_vol()) or other types even
486 to have not effect at all (i.e. change_attack()).
487 - Implemented built-in script function "sh_left()".
488 - Implemented built-in script function "sh_right()".
489 - Implemented built-in script function "min()".
490 - Implemented built-in script function "max()".

492 was loaded.
493 - NKSP built-in wait() script function: abort script execution if
494 a negative or zero wait time was passed as argument (since this is
495 a common indication of a bug either of the script or even of the
496 engine, which could lead to RT instability or even worse).
497 - ScriptVM: Implemented automatic suspension of RT safety
498 threatening scripts.

511 - Implemented built-in script function "fade_out()".
512 - Fixed acceptance of wrong data type of parameters passed to built-in
513 script functions "change_vol()", "change_tune()", "change_pan()",
514 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
515 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

517 - Added built-in script function "get_event_par()" and implemented some
518 of its possible parameter selections.
519 - Added built-in script function "set_event_par()" and implemented some
520 of its possible parameter selections.
521 - Fixed a bunch of scheduler time related bugs.
522 - Fixed polyphonic variables not being reset to zero after usage.
523 - Built-in "ignore_event()" function: argument is now optional, like with
524 built-in function "ignore_controller()".
525 - Implemented built-in script function "change_velo()".
526 - Implemented built-in script function "change_note()".
527 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
528 intuitive behavior if used in combination with "change_vol_time()" or
529 "change_tune_time()" respectively: now tuning/volume changes are only
530 assigned (without delay) immediately to a new note if the respective
531 timing function has not been called before, otherwise the volume/tuning
532 changes are automatically faded (before, only the event's time stamp was
533 relevant).
534 - Implemented built-in script function "array_equal()".
535 - Implemented built-in script function "search()".
536 - Implemented built-in script function "sort()".
537 - NKSP Fix: Never suspend "init" event handlers.

539 available for gig format engine).
540 - Added built-in script constant "$NKSP_LINEAR".
541 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
542 - Implemented built-in script function "change_vol_curve()".
543 - Implemented built-in script function "change_tune_curve()".
544 - built-in "play_note()" function now supports a sample playback start
545 offset with argument 3, where special value -1 means to use the regular
546 sample offset as defined by the instrument file.
547 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
548 - Built-in variable $EVENT_NOTE is now a read-only variable.
549 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
550 - built-in "play_note()" function now accepts -2 for its fourth argument
551 (note duration) which means the life time of the note shall be sticked
552 to the requested note number of argument 1.
553 - Fix: built-in "play_note()" function now returns 0 as result value if
554 -1 was passed for its fourth argument (note duration) and the respective
555 parent note is already gone.
556 - Implemented built-in script function "change_play_pos()".
557 - NKSP language: Added support for user declared const array variables.
558 - NKSP language: Raise parser warning if array variable is accessed with
559 an index that exceeds the array's size.
560 - NKSP language fix: Unknown characters were not handled correctly.
561 - NKSP language: Added support for "synchronized .. end synchronized"
562 code blocks.
563 - Implemented built-in script function "abort()" which allows to abort
564 another script handler by passing its callback ID.
565 - Fixed potential memory access bug and potential undefined behavior of
566 "init" event handlers.
567 - Print a time stamp along to each call of built-in function "message()".
568 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
569 to retrieve all code blocks filtered out by the preprocessor.

577 - Added built-in constant $CALLBACK_STATUS_RUNNING.
578 - Removed max. value limitation of built-in functions "change_attack()",
579 "change_decay()" and "change_release()" to i.e. allow passing 2000000
580 for doubling the respective time.
581 - NKSP script editor syntax highlighting API: Fixed app termination due
582 to a lexer start condition stack underrun.
583 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
584 USE_CODE_IF_NOT() preprocessor statements.
585 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
586 can be set to disable all subsequent built-in "message()" function calls
587 on preprocessor level.
588 - Implemented built-in script function "change_sustain()".

627 - fixed compilation with gcc 4.7
628 - fixed configure script error with old autoconf versions

631 - modernized configure script
632 - fixed linkage error when building with
633 LDFLAGS="-Wl,--no-undefined" (#190)
634 - fixed compilation with Clang 3.2
635 - removed usage of deprecated Automake variable INCLUDES

642 on the process's main thread
643 - fixed build error on newer MinGW
644 - support building with older jack versions

648 in order to get rid of warnings from automake 1.14
649
650 * general changes:
651 - Refactoring: moved the independent code from
652 the Gigasampler format engine to base classes
653 - command line option '--profile' is currently disabled, since the
654 respective profiling code is currently broken
655 - Introduced support for optional environment variable
656 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
657 where the sampler shall look for instrument editor plugins
658 (patch by Luis Garrido, slightly modified).
659 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
660 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
661 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
662 note (in this implementation of the sampler its simply hard routed to
663 the 1st effect send of the sampler channel, no matter what the actual
664 effect type is)
665 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
666 note (in this implementation of the sampler its simply hard routed to
667 the 2nd effect send of the sampler channel, no matter what the actual
668 effect type is)
669 - implemented support for internal LADSPA effects
670 - raised limit of program change queue from 100 to 512
671 (as suggested by Alex Stone)
672 - implemented sine LFO, pulse LFO and saw LFO
673 - experimental support for per voice equalization
674 - added command line option --exec-after-init
675 - Introduced new C++ API method:
676 EngineChannel::InstrumentFileName(int index)
677 allowing to retrieve the whole list of files used for the loaded
678 instrument on an engine channel (a.k.a. part). Some GigaStudio
679 instruments for example are splitted over several files like
680 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
681 - Added new C++ API method Sampler::GetGlobalMaxVoices().
682 - Added new C++ API method Sampler::GetGlobalMaxStreams().
683 - Added new C++ API method Sampler::SetGlobalMaxVoices().
684 - Added new C++ API method Sampler::SetGlobalMaxStreams().
685 - Various "const" and "restrict" optimizations.
686 - all engines: add pan CC value to instrument pan parameter before
687 applying panning, instead of using two separate pan functions in
688 series (#182)
689 - added a lock guard class for exception safe mutex handling and
690 used it everywhere appropriate
691 - Immediately apply scale tuning changes to active voices.
692 - Exposed scale tuning to C++ API (along to the already existing standard
693 SysEx way).
694 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
695 and broken for ppc64. (Seq_cst loads and stores are actually not
696 used in LS, so the bug wasn't noticable.)
697 - lsatomic.h: added ARMv7 support
698 - Added support for multiple MIDI input ports per sampler channel (and
699 added various new C++ methods for this new feature / design change, old
700 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
701 as deprecated but are still there and should provide full behavior
702 backward compatibility).
703 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
704 unsafe and caused compilation error with clang 2.x).
705 - Bugfix: only process the latest MIDI program change event.
706 - Introducing the LSCP shell, which provides convenient control of the
707 sampler from the command line by providing LSCP aware features.
708 - VirtualMidiDevice: Added support for program change.
709 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
710 - VirtualMidiDevice: Added support for pitch bend.
711 - Aftertouch: extended API to explicitly handle channel pressure and
712 polyphonic key pressure events (so far polyphonic pressure was not
713 supported at all, and channel pressure was rerouted as CC128 but not
714 used so far).
715 - Added initial support for real-time instrument scripts. The script VM
716 code is shared by all sampler engine implemementations, however only the
717 gig file format currently provides support for storing instrument scripts
718 (as LinuxSampler extension to the original GigaStudio 4 format).
719
720 * Gigasampler format engine:
721 - implemented the "round robin keyboard" dimension
722 - fixed round robin and random dimensions for cases when number of
723 dimension zones is not a power of two

725 key
726 - bugfix: pitch LFO controller "internal+aftertouch" was broken
727 - bugfix: filter keyboard tracking was broken
728 - filter performance fix (an unnecessary copy was made of the
729 filter parameters in each sub fragment)
730 - handle special case when pan parameter in gig file has max or
731 min value
732 - Exclusive Groups: don't ever stop voices of the same note,
733 doesn't sound naturally with a drumkit
734 - fixed EG1 modulation when attack or release is zero
735 - Fixed support for 'aftertouch' attenuation controller.
736 - Fixed crash that happened with velocity split sounds under certain
737 conditions (see also previous commit on libgig).
738 - fixed behaviour of filter LFO
739
740 * SFZ format engine:

770 - added support for loop_mode=one_shot
771 - fixed playback of 16 bit wav files on big endian CPUs
772 - added support for Ogg Vorbis sample files
773 - use loop markers from sample file if loop_start and loop_end are
774 not set in sfz file
775 - implemeted filters. Filter types: lowpass, bandpass, bandreject
776 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
777 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
778 cutoff_cc, cutoff_chanaft.
779 - bugfix: zero ampeg_sustain didn't work

968 the driver will automatically connect to other CoreMIDI clients' ports
969 (e.g. external MIDI devices being attached to the Mac)
970 - added support for MIDI note on velocity filter
971 - CoreMIDI: fixed memory deallocation error
972 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
973 virtual keyboards in frontends / instrument editors being stuck.

1142 crashes and noise on such transitions).
1143 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1144 (fixes #208)
1145 - Fixed bug in LSCP grammar definition which caused a statement like
1146 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1147 practically irrelevant, however it caused problems with the new LSCP
1148 shell's auto completion feature).
1149 - Fixed MIDI program change messages being ignored if quickly executed
1150 after each other (fixes #231).
1151
1152 Version 1.0.0 (31 July 2009)
1153
1154 * packaging changes:
1155 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1167 directory of liblinuxsampler dll (look in the same directory and one
1168 directory above)
1169 - configure script fix: removed unconditional use of SSE
1170 - fixed building with sqlite installed in a non-standard directory
1171 - when cross-compiling, don't try to create instruments.db

1177 (fixes bug #70, patch by Ronald Baljeu)
1178 - fixed endless loop which occured when loading an instrument editor
1179 plugin DLL on Windows systems failed
1180 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1181 - optimized the SynchronizedConfig class so it doesn't wait
1182 unnecessarily long after an update

1184 events (e.g. to highlight the pressed keys on the virtual keyboard
1185 of gigedit)
1186 - added support for triggering notes by instrument editors (see above)
1187 - be verbose on DLL load errors (on Linux)
1188 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1192 - experimental support for running LinuxSampler as a DSSI, LV2 and
1193 VST plugin

1199 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1200 - automatic stacktrace mechanism is now turned off by default and can
1201 be switched on by command line option "--stacktrace" (the automatic
1202 stacktrace mechanism seems to be broken on most systems at the moment)
1203 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1204 a pointer to the launched InstrumentEditor object
1205 - added optional 3rd party user data parameter for following
1206 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1207 InstrumentEditor::Launch(),

1209 - theoretical fix: made SynchronizedConfig follow C++0x memory
1210 model more strictly
1211 - fixes for using large audio device buffers
1212 - Windows: add the installation directory to the DLL search path
1213 when loading an editor plugin (solves problems with VST and

1218 - removed the nonsense audio channel constraint (which was hard coded to
1219 max. 100 audio channels) for most audio drivers
1220 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1221 opposed to the LSCP specs
1222 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1223 reflected the wrong value
1224 - fixed a memory management bug in ASIO driver
1225 - Makefile fix: JACK_CFLAGS wasn't used
1226 - JACK: use jack_client_open instead of the deprecated

1233 win64)
1234 - VST: added support for sample rate and buffer size changes
1235 - VST: close editor (Fantasia) when the VST is removed
1236 - VST: avoid opening Fantasia more than once for each VST instance

1238 energyXT)
1239 - VST: changed number of output channels from one stereo to 16
1240 stereo
1241 - added channel routing, fxsends and midi maps to the settings
1242 stored in the plugin state
1243 - performance optimization of AudioChannel::MixTo() and
1244 AudioChannel::CopyTo() methods using GCC vector exensions
1245 (if available)

1253 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1254 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1255 CoreMidi or AU
1256 - fixed mingw-w64 compilation error in MME driver
1257 - made program change handling in MIDI thread real-time safe by

1269 instrument database compilable
1270 - added instrument database support on Windows
1271 works with both standalone mode and VST plugin.
1272 the instruments DB file is located in
1273 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1274 databases for each windows user
1275 if no DB is present it automatically creates the .linuxsampler subdir
1276 and then creates an empty DB
1277 - fixed recursive import, which was broken on Windows
1278
1279 * Gigasampler format engine:
1280 - fixed a memory leak that could happen when a channel was deleted
1281 while notes were playing
1282 - made it possible to load an instrument even if the audio thread
1283 isn't running
1284 - added partial support for the "Controller Triggered" MIDI rule,
1285 enough for piano gigs with pedal noise samples
1286 - minor fix: only mark FX sends as being modified if really the
1287 respective FX send MIDI controller was used
1288 - added support for GM global device volume SysEx message
1289 (can be selected at compile time to either apply globally to the
1290 whole sampler [default] or only to the sampler channels that are
1291 connected to the respective MIDI input port the SysEx message arrived
1292 on)
1293 - bugfix: notes triggered at position 0 in the audio buffer were
1294 sometimes wrongly killed in the same buffer, causing no sound to
1295 be played
1296 - added support for chromatic / drumkit mode Roland GS Sysex message
1297 which is usally used to switch a part between chromatic sounds and
1298 drumkit sounds (as opposed to their common default setting of MIDI
1299 part 10 being a drumkit part and all other ones chromatic parts), in
1300 LS however one can switch between the first 16 MIDI instrument maps
1301 defined for the sampler
1302 - made it possible to create multiple sample channels even if the
1303 audio thread isn't running
1304 - fixed crash when removing channel with active voices (#116)
1305 - bugfix: on sample reference changes (instrument editor), only
1306 un-cache the respective sample if it's really not used by any
1307 sampler engine anymore
1308 - re-cache samples in case they were changed by an instrument editor,
1309 e.g. when a sample was added while playing (#82)
1310 - fixed hanging notes which occured when note-off event had the exact
1311 same time stamp as the voice's note-on event and occured both in the
1312 same audio fragment cycle (fixes bug #112)
1313 - added support for the "fine tune" and "pitch bend range"
1314 instrument-level gig parameters
1315 - fixed minor artifacts in pitch bend handling
1316 - added support for GS Reset SysEx message
1317 - allow gig files to use unlimited downward pitch shifting
1318 - added a limit check for upward pitch shifting
1319 - bugfix: sometimes, when playing a note twice fast, the second
1320 note was silent
1321 - fixed crash happening when a pitch bend event arrived at the
1322 same time a new instrument was loading
1323
1324 * LSCP server:
1325 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1326 react on MIDI data arriving on certain sampler channels (so far only
1327 Note-On and Note-Off events are sent via this LSCP event)
1328 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1329 react on MIDI data arriving on certain MIDI input devices (so far only
1330 Note-On and Note-Off events are sent via this LSCP event)
1331 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1332 SET DB_INSTRUMENT FILE_PATH
1333 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1334 frontends to send MIDI messages to specific sampler channel
1335 - added two additional fields to GET FILE INSTRUMENT INFO command -
1336 KEY_BINDINGS and KEYSWITCH_BINDINGS
1337 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1338 was incorrect
1339 - Optimized the retrieval of the MIDI instrument mappings
1340 - added new LSCP command "SET VOICES" to globally alter the maximum
1341 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1342 be triggered respectively
1343 - added new LSCP command "SET STREAMS" to globally alter the maximum
1344 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1345 which will be triggered respectively
1346 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1347 a gigedit file dialog is opened)
1348 - close all connections when LSCPServer is deleted
1349 - hard close of all sockets on exit
1350 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1351 driver
1352
1353 * Bug fixes:
1354 - fixed a crash which occurs when removing a sampler channel waiting
1355 to start instrument loading after another channel
1356 - fixed a crash which occurs when removing a sampler channel with
1357 instrument loading in progress (bug #113)
1358 - fixed termination caused by uncaught exception when adding MIDI
1359 instrument with PERSISTENT load mode
1360 - fixed possible iterator invalidations when resetting the sampler
1361 - fixed memory leaks when issuing the following LSCP commands:
1362 GET AUDIO_OUTPUT_DRIVER INFO
1363 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1364 GET MIDI_INPUT_DRIVER INFO
1365 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1366 - fixed possible compilation error when sqlite is not present
1367 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1368 - fixed crash when changing the audio output device of a sampler
1369 channel with loaded instrument and start playing notes
1370 - fixed endless loop in Engine::SuspendAll() (bug #120)
1371 - fixed a low-level atomic load function that was broken on 64-bit
1372 PowerPC, which probably could cause crashes on that platform
1373 - fixed a memory management error which could cause a crash when a
1374 plugin was unloaded
1375 - bugfix: two private structs had the same name, which could cause
1376 problems if the linker chose the wrong constructor
1377 - fixed low-level ConditionServer usage bug that caused lockups on
1378 Windows
1379
1380
1381 Version 0.5.1 (6 December 2007)
1382
1383 * packaging changes:
1384 - added autoconf checks for pthread library
1385 - added autoconf check for pthread bug found on certain NPTL-enabled
1386 glibc versions (see Gentoo bug report #194076)
1387 - added autoconf checks for MS Windows
1388
1389 * general changes:
1390 - bugfix: the thread used by an editor plugin didn't die when the
1391 editor closed
1392 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1393 out all the space. operator--() did not apply size_mask after
1394 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1395 order to avoid problems with the _NonVolatileReader functions.
1396 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1397 GetWriteSpace(). Since this function is currently only used in
1398 the stream's qsort() compare function, it didn't trigger any
1399 bugs.
1400 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1401 24bit mode too. Faster method to read 24bit words on little
1402 endian machines (x86): replaced 3 byte reads + shifts with a 1
1403 unaligned 32bit read and shift
1404 - experimental support for MS Windows (MIDI input via MME, AUDIO
1405 output via ASIO)
1406 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1407 - support for monitoring the total number of active disk streams
1408 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1409 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1410
1411 * AUDIO driver:
1412 - added Windows ASIO low latency audio driver
1413
1414 * MIDI driver:
1415 - added MME Windows MIDI driver
1416
1417 * LSCP server:
1418 - added support for Windows style path / filenames, however with
1419 forward slash path separators instead of backslash
1420 (i.e. "C:/foo/bar.gig")
1421 - allow naughty liblscp to send non-string device parameters within
1422 apostrophes as well
1423 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1424 "LIST FILE INSTRUMENTS <file>" and
1425 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1426 about an arbitrary instrument file on the system where the sampler is
1427 running on
1428
1429 Version 0.5.0 (15 October 2007)
1430
1431 * packaging changes:
1432 - config.h is not going to be installed along with liblinuxsampler's
1433 API header files anymore
1434 - only the API relevant header (and source) files will be exported to
1435 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1436 - added completely new XCode project files for Mac OSX which is now
1437 capable to execute our autoconf environment, thus no need anymore
1438 to maintain the compile time configuration file (osx/version.h) for
1439 OSX manually (patch by Toshi Nagata)
1440 - fixed buggy boolean --enable-foo / --disable-foo configure script
1441 parameters
1442 - global.h now only covers global definitions that are needed for the
1443 C++ API header files, all implementation internal global definitions
1444 are now in global_private.h
1445 - atomic.h is not exposed to the C++ API anymore
1446 - no need to include config.h anymore for using LS's API header files
1447 - fixed warnings in API doc generation
1448
1449 * general changes:
1450 - replaced the old, confusing MIDI program change mechanism by a
1451 flexible MIDI instrument mapper which allows to map arbitrary
1452 (MIDI bank, MIDI program) pairs with arbitrary
1453 (engine type, instrument file, file index) triplets which will be
1454 loaded on the respective channel when such MIDI program change
1455 messages arrive, beside that, each entry allows to define a life-time
1456 strategy for the instrument, so the user can define whether the
1457 instrument should i.e. be permanently loaded (to be able to switch
1458 quickly among sounds) or i.e. loaded just on demand when the
1459 respective program change arrives (to safe RAM space), as well as a
1460 global volume factor for each entry, so the user can adjust the volume
1461 dynamic of his mapped instrument collection without having to modify
1462 the instrument files, also one can manage arbitrary amount of such
1463 MIDI instrument maps and assign each sampler channel individually
1464 a certain map, so that i.e. separation of normal instruments and
1465 drumkits is possible
1466 - new notification events for tracking changes to audio/MIDI devices,
1467 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1468 - sampler was limited to load max. 200 instruments in the background
1469 due to a constant size RingBuffer FIFO which is now replaced by a
1470 dynamic (unlimited) size std::list FIFO
1471 - added FX sends, these allow to route audio signals to arbitrary audio
1472 output channels for being processed by external effect processors
1473 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1474 controllers
1475 - global (sampler wide) volume can now be controlled at runtime
1476 - Implemented new, improved notification system
1477 - fixed compilation errors regarding OSX
1478 (patch by Toshi Nagata)
1479 - implemented instruments database
1480 - added support for escape sequences to the instruments database
1481 - added highly experimental support for on-the-fly instrument editing
1482 within the sampler's process (by using instrument editor plugins),
1483 you'll notice the new "Registered instrument editors:" message on
1484 startup, added a new LSCP command:
1485 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1486 to spawn a matching instrument editor for the instrument on the
1487 given sampler channel, the plugin path can be overridden at compile
1488 time with ./configure --enable-plugin-dir=/some/dir
1489 - added experimental code for synchronizing instrument editors hosted
1490 in the sampler's process to safely edit instruments while playing
1491 without a crash (hopefully) by either suspending single regions
1492 wherever possible or if unavoidable whole engine(s)
1493 - fixed several issues in fundamental "Thread" class: set scheduling
1494 policy and priority on thread level, set a minimum stack size for
1495 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1496 threads simply inherited properties of starting thread instead of
1497 setting their own policy and priority
1498 - minor fix in our automatic stack trace mechanism on crashes, the
1499 main process did not wait for the stack trace process to finish
1500 its output
1501 - fixed some minor memory leaks
1502 - reenabled assembly features support, at the moment only for
1503 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1504 - minor assembly fix in x86 features detection (don't use the PIC
1505 register, to avoid relocations in the text segment at runtime)
1506 - POSIX callback functions of Thread.h are hidden
1507
1508 * MIDI driver:
1509 - dispatch bank select (MSB and LSB) messages
1510
1511 * audio driver:
1512 - the ALSA audio output driver parameters now reflect the correct
1513 parameter value ranges for the respective selected sound card
1514 (patch by Till Wimmer, a bit fixed and extended)
1515
1516 * Gigasampler format engine:
1517 - if a filter is used and EG2 finishes before EG1, let the voice
1518 die when EG2 has finished (this fixes a problem with clicks and
1519 voice starvation for some gigs)
1520 - playback is no longer disabled during instrument loading
1521 - all notes playing on a channel that changes its instrument keep
1522 playing with the old instrument until they get a note off
1523 command
1524 - EG fix: a release value of zero could cause noises or crash
1525 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1526 - EG fine tuning: when attack is zero the EG starts at a level
1527 above max sustain level, which means that there is a decay phase
1528 even if sustain is 100%
1529 - more EG fixes: the level could sometimes go below zero and cause
1530 noises or crashes
1531 - minor fix of EGDecay (patch by Toshi Nagata)
1532 - fixed compiler error when --enable-override-filter-type was
1533 supplied to the configure script (fixes #46)
1534 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1535 instead of a fix value
1536 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1537 127 (solo mode) only kill voices if the respective mode really
1538 changed
1539
1540 * LSCP server:
1541 - fixed compile time error for old Bison versions
1542 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1543 - parser now supports extended ASCII character set
1544 (up to ASCII code 255, i.e. includes now umlauts and accents)
1545 - filename arguments in LSCP commands now allow to use escape
1546 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1547 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1548 code value like \xf2) (fixes bug #24)
1549 - the following LSCP commands now also support escape sequences for at
1550 least one of their text-based parameters (i.e. name, description):
1551 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1552 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1553 "SET DB_INSTRUMENT_DIRECTORY NAME",
1554 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1555 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1556 "FIND DB_INSTRUMENT_DIRECTORIES"
1557 - returns verbose syntax errors (line and column where syntax error
1558 occured, the unexpected character and the actually expected, possible
1559 character(s), the latter only if less than 5 possibilities)
1560 - made sure that LSCP syntax is not affected by gigedit locale
1561 settings
1562 - bugfix regarding strings parameter lists: all comma separated lists
1563 of strings were treated as being one string containing commas
1564 (fixes #57)
1565
1566 * Bug fixes:
1567 - fixed crash occurring on certain LSCP scripts (Bug 39)
1568 - another thread safety fix for lscp "load engine" and "set
1569 channel audio output device"
1570 - fixed a crash which occurs when reassigning the same engine
1571 on a sampler channel with connected MIDI device
1572 - fixed a crash which occurs when changing the number of ports of a MIDI
1573 device connected to a sampler channel to number less then or equal
1574 to the index of the port to which the sampler channel is connected.
1575 - The previous bindings were not been disconnected when altering
1576 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1577 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1578 - The active stream/voice count statistic was incorrect.
1579 - notification events were not been sent for some sampler
1580 channel changes
1581 - added default min and max values to restrict the number of allowed
1582 audio output channels and MIDI input ports
1583 - the connection to the PCM interface is now closed when destroying
1584 an audio output device
1585 - files with slash in their path or filename could not be loaded
1586
1587 * test cases:
1588 - updated and fixed (haven't been touched in a while)
1589
1590 Version 0.4.0 (24 November 2006)
1591
1592 * packaging changes:
1593 - changed deprecated copyright attribute to license; added ldconfig
1594 to post-(un)install steps; added devel package for liblinuxsampler;
1595 to linuxsampler.spec (RPM)
1596 - install necessary development header files for allowing 3rd party
1597 applications to link against liblinuxsampler
1598 - liblinuxsampler's API documentation can be generated with 'make docs'
1599 (Doxygen required)
1600 - added benchmark to automatically detect the best triangle LFO
1601 implementation (currently either an integer math solution or a
1602 di-harmonic approximation), automatic detection can be overriden
1603 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1604 configure script argument though (mandatory for cross-compilation)
1605 - do not automatically pick optimized gcc flags if the user already
1606 provided some on his own (as CXXFLAGS)
1607 - added compile time option to disable processing of All-Notes-Off MIDI
1608 messages
1609 - added compile time options to allow disabling the various audio and
1610 MIDI drivers
1611 - fixed automatic GCC CPU switch detection on PPC
1612 (patch by Ebrahim Mayat)
1613
1614 * Gigasampler format engine:
1615 - extensive synthesis optimization
1616 (reimplementation of EGs and LFO(s), removed synthesis parameter
1617 prerendering and the synthesis parameter matrix in general, splitting
1618 each audio fragment into subfragments now where each subfragment uses
1619 constant pitch and filter coefficients. The volume coefficient is
1620 linearly interpolated inside a subfragment, unless
1621 --disable-interpolate-volume is set.)
1622 - fine tuning of the EG modulation parameters
1623 - improved filter cutoff calculation by adding support for the
1624 following gig parameters: Cutoff freq (used when no cutoff
1625 controller is defined), Control invert, Minimum cutoff, Velocity
1626 curve and Velocity range. The keyboard tracking now scales
1627 cutoff frequency instead of resonance.
1628 - added support for gig parameter Resonance.
1629 - fixed bug in sysex handling (patch by Juan Linietsky)
1630 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1631 which can be overridden with --enable-global-attenuation
1632 - EG fixes: made the length of "attack hold" stage more
1633 accurate. Release stage can now start before attack stage
1634 ends. Cancel release didn't work when sustain was zero. Attack
1635 time now has a minimal value to prevent clicks.
1636 - fixed pitch changes larger than one octave
1637 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1638 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1639 all modes can be altered via standard GM messages, that is CC5 for
1640 altering portamento time, CC65 for enabling / disabling portamento
1641 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1642 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1643 parameter) and crossfade
1644 - added support for the "attenuation controller threshold" gig
1645 parameter
1646 - added smoothing of volume changes caused by control change
1647 messages
1648 - sample loop parameters are now taken from the DimensionRegion
1649 instead of the wave chunk
1650 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1651 not equal to a power of two
1652 - reimplementation of the filter algorithm. The new filter is more
1653 accurate and supports all gig filter types, including bandreject
1654 and lowpass turbo.
1655 - real support for 24 bit samples - samples are not truncated to
1656 16 bits anymore
1657 - support for aftertouch (channel pressure, not polyphonic
1658 aftertouch)
1659 - LFO1 behaviour fixed (dampening from max volume instead of
1660 amplifying from 0)
1661
1662 * LSCP server:
1663 - fixed application exit on broken pipe error (fixes bug #20)
1664 - fixed the notification messages delay due to lack of
1665 network activity (fixes bug #26)
1666 - fixed parser bug which occured on space(s) within device parameters
1667 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1668
1669 * audio driver:
1670 - added aRts audio output driver (by no means RT safe)
1671
1672 * MIDI driver:
1673 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1674 messages several times instead of once
1675 - API extension for MIDI drivers which already supply exact time stamps
1676 for events (i.e. for offline rendering based MIDI drivers)
1677 - added checks for bad MIDI data
1678
1679 * linuxsampler application:
1680 - show available sampler engine types on startup
1681
1682 * general changes:
1683 - support for muting sampler channels and solo mode of the same, two new
1684 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1685 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1686 introduced for this, the behavior is the same like on a mixer console
1687 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1688 --enable-process-muted-channels which can be used to enable the
1689 processing of muted channels.
1690 - support for sostenuto pedal
1691 - support for monitoring the total number of active voices
1692 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1693 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1694 - fixed some memory management errors
1695 - fixed some concurrency problems that could lead to crashes when
1696 LSCP commands were executed
1697 - fixed crash when instrument loading failed previously on the same
1698 sampler channel (fixes bug #36)
1699
1700 Version 0.3.3 (15 July 2005)
1701
1702 * packaging changes:
1703 - fixed compilation with gcc 4.0
1704
1705 * Gigasampler format engine:
1706 - LFO preprocessing was performed even though the respective LFO was
1707 disabled by the instrument patch (minor efficiency fix)
1708 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1709 for volume ramp downs in the same fragment (needed for current voice
1710 stealing implementation) then simply inform the user with a warning
1711 about possible click sounds and reduce the volume ramp down
1712 appropriately instead of cancelling the audio device connection
1713
1714 Version 0.3.2 (24 June 2005)
1715
1716 * packaging changes:
1717 - updated autotools build files to compile on OS X
1718 (conditional compilation of CoreMIDI and MidiShare drivers)
1719 - hand-crafted assembly optimization code can be disabled with
1720 './configure --disable-asm' (definitely not recommended)
1721 - fixed 'make dist' rule to include all necessary files
1722 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1723 (due to 'dist-bzip2' automake option)
1724
1725 * Gigasampler format engine:
1726 - support for the gig parameters for "release velocity response" curves
1727 - fine tuning of the EGADSR envelope
1728 - volume of release triggered samples now depends on note-on velocity,
1729 note length and gig parameter "release trigger decay" instead of
1730 note-off velocity.
1731 - revised voice stealing
1732 (fixes crash and endless loop caused by voice stealing)
1733 - don't reset scale tuning on instrument or audio output device change
1734 - handle key group conflicts right at the beginning of each fragment
1735 instead of when the respective voice is actually launched
1736 (fixes undefined behavior if stolen voices belonged to a key group -
