File size: 96395 byte(s)
* Added support for MIDI CC #96 (data increment).

* Added support for MIDI CC #97 (data decrement).

* Bumped version (2.1.1.svn34).

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

442 - Implemented built-in script function "dec()".
443 - NKSP language fix: division expressions were evaluated too often.
444 - NKSP language fix: string concatenation operator was right
445 associative instead of left (to right).
446 - NKSP language correction: allow empty statements in entire language
447 (i.e. "if end if").

462 - Fixed all change_*() built-in script functions to apply their
463 synthesis parameter changes immediately in case the respective note
464 was triggered at the same time, instead of scheduling the parameter
465 change, especially because it would cause some parameter types's
466 changes either to be ramped (i.e. change_vol()) or other types even
467 to have not effect at all (i.e. change_attack()).
468 - Implemented built-in script function "sh_left()".
469 - Implemented built-in script function "sh_right()".
470 - Implemented built-in script function "min()".
471 - Implemented built-in script function "max()".

473 was loaded.
474 - NKSP built-in wait() script function: abort script execution if
475 a negative or zero wait time was passed as argument (since this is
476 a common indication of a bug either of the script or even of the
477 engine, which could lead to RT instability or even worse).
478 - ScriptVM: Implemented automatic suspension of RT safety
479 threatening scripts.

492 - Implemented built-in script function "fade_out()".
493 - Fixed acceptance of wrong data type of parameters passed to built-in
494 script functions "change_vol()", "change_tune()", "change_pan()",
495 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
496 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

498 - Added built-in script function "get_event_par()" and implemented some
499 of its possible parameter selections.
500 - Added built-in script function "set_event_par()" and implemented some
501 of its possible parameter selections.
502 - Fixed a bunch of scheduler time related bugs.
503 - Fixed polyphonic variables not being reset to zero after usage.
504 - Built-in "ignore_event()" function: argument is now optional, like with
505 built-in function "ignore_controller()".
506 - Implemented built-in script function "change_velo()".
507 - Implemented built-in script function "change_note()".
508 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
509 intuitive behavior if used in combination with "change_vol_time()" or
510 "change_tune_time()" respectively: now tuning/volume changes are only
511 assigned (without delay) immediately to a new note if the respective
512 timing function has not been called before, otherwise the volume/tuning
513 changes are automatically faded (before, only the event's time stamp was
514 relevant).
515 - Implemented built-in script function "array_equal()".
516 - Implemented built-in script function "search()".
517 - Implemented built-in script function "sort()".
518 - NKSP Fix: Never suspend "init" event handlers.

520 available for gig format engine).
521 - Added built-in script constant "$NKSP_LINEAR".
522 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
523 - Implemented built-in script function "change_vol_curve()".
524 - Implemented built-in script function "change_tune_curve()".
525 - built-in "play_note()" function now supports a sample playback start
526 offset with argument 3, where special value -1 means to use the regular
527 sample offset as defined by the instrument file.
528 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
529 - Built-in variable $EVENT_NOTE is now a read-only variable.
530 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
531 - built-in "play_note()" function now accepts -2 for its fourth argument
532 (note duration) which means the life time of the note shall be sticked
533 to the requested note number of argument 1.
534 - Fix: built-in "play_note()" function now returns 0 as result value if
535 -1 was passed for its fourth argument (note duration) and the respective
536 parent note is already gone.
537 - Implemented built-in script function "change_play_pos()".
538 - NKSP language: Added support for user declared const array variables.
539 - NKSP language: Raise parser warning if array variable is accessed with
540 an index that exceeds the array's size.
541 - NKSP language fix: Unknown characters were not handled correctly.
542 - NKSP language: Added support for "synchronized .. end synchronized"
543 code blocks.
544 - Implemented built-in script function "abort()" which allows to abort
545 another script handler by passing its callback ID.
546 - Fixed potential memory access bug and potential undefined behavior of
547 "init" event handlers.
548 - Print a time stamp along to each call of built-in function "message()".

558 - Added built-in constant $CALLBACK_STATUS_RUNNING.
559 - Removed max. value limitation of built-in functions "change_attack()",
560 "change_decay()" and "change_release()" to i.e. allow passing 2000000
561 for doubling the respective time.
562 - NKSP script editor syntax highlighting API: Fixed app termination due
563 to a lexer start condition stack underrun.
564 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
565 USE_CODE_IF_NOT() preprocessor statements.
566 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
567 can be set to disable all subsequent built-in "message()" function calls
568 on preprocessor level.
569 - Implemented built-in script function "change_sustain()".
570 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
571 to avoid the editor app to crash on ill-formed text input.

604 directories are separate
605 - Mac OS X: made it possible to specify plugin installation dir to
606 configure
607 - Mac OS X: Makefile fix for the install-strip target
608 - fixed compilation with gcc 4.7
609 - fixed configure script error with old autoconf versions

613 - fixed linkage error when building with
614 LDFLAGS="-Wl,--no-undefined" (#190)
615 - fixed compilation with Clang 3.2
616 - removed usage of deprecated Automake variable INCLUDES
617 - fixed building with C++11
618 - build fix: ChangeFlagRelaxed.h was missing in makefile

623 on the process's main thread
624 - fixed build error on newer MinGW
625 - support building with older jack versions

629 in order to get rid of warnings from automake 1.14
630
631 * general changes:
632 - Refactoring: moved the independent code from
633 the Gigasampler format engine to base classes
634 - command line option '--profile' is currently disabled, since the
635 respective profiling code is currently broken
636 - Introduced support for optional environment variable
637 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
638 where the sampler shall look for instrument editor plugins
639 (patch by Luis Garrido, slightly modified).
640 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
641 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
642 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
643 note (in this implementation of the sampler its simply hard routed to
644 the 1st effect send of the sampler channel, no matter what the actual
645 effect type is)
646 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
647 note (in this implementation of the sampler its simply hard routed to
648 the 2nd effect send of the sampler channel, no matter what the actual
649 effect type is)
650 - implemented support for internal LADSPA effects
651 - raised limit of program change queue from 100 to 512
652 (as suggested by Alex Stone)
653 - implemented sine LFO, pulse LFO and saw LFO
654 - experimental support for per voice equalization
655 - added command line option --exec-after-init
656 - Introduced new C++ API method:
657 EngineChannel::InstrumentFileName(int index)
658 allowing to retrieve the whole list of files used for the loaded
659 instrument on an engine channel (a.k.a. part). Some GigaStudio
660 instruments for example are splitted over several files like
661 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
662 - Added new C++ API method Sampler::GetGlobalMaxVoices().
663 - Added new C++ API method Sampler::GetGlobalMaxStreams().
664 - Added new C++ API method Sampler::SetGlobalMaxVoices().
665 - Added new C++ API method Sampler::SetGlobalMaxStreams().
666 - Various "const" and "restrict" optimizations.
667 - all engines: add pan CC value to instrument pan parameter before
668 applying panning, instead of using two separate pan functions in
669 series (#182)
670 - added a lock guard class for exception safe mutex handling and
671 used it everywhere appropriate
672 - Immediately apply scale tuning changes to active voices.
673 - Exposed scale tuning to C++ API (along to the already existing standard
674 SysEx way).
675 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
676 and broken for ppc64. (Seq_cst loads and stores are actually not
677 used in LS, so the bug wasn't noticable.)
678 - lsatomic.h: added ARMv7 support
679 - Added support for multiple MIDI input ports per sampler channel (and
680 added various new C++ methods for this new feature / design change, old
681 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
682 as deprecated but are still there and should provide full behavior
683 backward compatibility).
684 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
685 unsafe and caused compilation error with clang 2.x).
686 - Bugfix: only process the latest MIDI program change event.
687 - Introducing the LSCP shell, which provides convenient control of the
688 sampler from the command line by providing LSCP aware features.
689 - VirtualMidiDevice: Added support for program change.
690 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
691 - VirtualMidiDevice: Added support for pitch bend.
692 - Aftertouch: extended API to explicitly handle channel pressure and
693 polyphonic key pressure events (so far polyphonic pressure was not
694 supported at all, and channel pressure was rerouted as CC128 but not
695 used so far).
696 - Added initial support for real-time instrument scripts. The script VM
697 code is shared by all sampler engine implemementations, however only the
698 gig file format currently provides support for storing instrument scripts
699 (as LinuxSampler extension to the original GigaStudio 4 format).
700

706 key
707 - bugfix: pitch LFO controller "internal+aftertouch" was broken
708 - bugfix: filter keyboard tracking was broken
709 - filter performance fix (an unnecessary copy was made of the
710 filter parameters in each sub fragment)
711 - handle special case when pan parameter in gig file has max or
712 min value
713 - Exclusive Groups: don't ever stop voices of the same note,

898 - VST bugfix: If the host called resume() before and after
899 changing sample rate or block size, the number of channels was
900 incorrectly set to two. This caused silence in Cubase 5.
901 - save engine type (gig, sfz or sf2) in plugin state

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

1024 - Added support for moving cursor left/right with arrow keys.
1025 - Added support for built-in LSCP reference documentation, which will
1026 automatically show the relevant LSCP reference section on screen as soon

1074 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1075 (i.e. return value of new script function "by_marks()").
1076 - Pass/preserve polyphonic variable data from respective "note" event
1077 handler to "release" event handler.
1078 - Fixed crash when using built-in script function "by_marks()".
1079

1084 channel to a different engine type
1085 - fixed crash when deleting a sampler channel or changing engine
1086 type while an instrument load was in progress
1087 - bugfix: playing a note while changing the instrument could cause
1088 a crash, or give "Handing back unknown region" error messages
1089 - bugfix: calling SET VOICES (which Fantasia does on start and
1090 refresh) could cause instruments to be unloaded
1091 - Mac OS X: fixed name collision of enum in EffectControl and
1092 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1093 - Mac OS X: fixed hanging threads
1094 - Windows: disabled the previous thread fix on non-Mac systems, as
1095 it caused hanging threads on Windows

1097 after MIDI/audio device creation failure
1098 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1099 instruments were uselessly precached with zero samples, however it still
1100 took the full preloading time and on 1st program change the respective
1101 instrument was completely reloaded again.
1102 - fixed handling of rapid bank select and program change messages
1103 sent to the same sampler channel (patch from the Open Octave
1104 project, slightly adjusted)

1123 crashes and noise on such transitions).
1124 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1125 (fixes #208)
1126 - Fixed bug in LSCP grammar definition which caused a statement like
1127 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1128 practically irrelevant, however it caused problems with the new LSCP
1129 shell's auto completion feature).
1130 - Fixed MIDI program change messages being ignored if quickly executed
1131 after each other (fixes #231).
1132
1133 Version 1.0.0 (31 July 2009)
1134
1135 * packaging changes:
1136 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1137 causing e.g. the libgig test to fail when
1138 "./configure --disable-jack-driver" was used
1139 (patch by Alexis Ballier)
1140 - fixed compilation with gcc 4.3
1141 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1145 - fixed building with libgig installed in a non-standard directory
1146 - minor fix in configure for mmsystem.h detection on MinGW
1147 - Windows: look for editor plugins and Fantasia using base
1148 directory of liblinuxsampler dll (look in the same directory and one
1149 directory above)
1150 - configure script fix: removed unconditional use of SSE
1151 - fixed building with sqlite installed in a non-standard directory
1152 - when cross-compiling, don't try to create instruments.db
1153 - fix for new mingw-w64 version, which has usleep
1154
1155 * general changes:
1156 - bugfix: on some POSIX systems instrument editor plugins refused to
1157 load as we used a non-portable Linux specific struct field
1158 (fixes bug #70, patch by Ronald Baljeu)
1159 - fixed endless loop which occured when loading an instrument editor
1160 plugin DLL on Windows systems failed
1161 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1162 - optimized the SynchronizedConfig class so it doesn't wait
1163 unnecessarily long after an update
1164 - added support for notifying instrument editors on note-on / note-off
1165 events (e.g. to highlight the pressed keys on the virtual keyboard
1166 of gigedit)
1167 - added support for triggering notes by instrument editors (see above)
1168 - be verbose on DLL load errors (on Linux)
1169 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1170 is only used by very few systems, most pick the int math
1171 implementation, which is usually faster)
1172 - fixes for audio drivers with varying buffer sizes
1173 - experimental support for running LinuxSampler as a DSSI, LV2 and
1174 VST plugin
1175 - notification events for stream/voice count statistics are now sent
1176 only when there are actual changes
1177 - added memory ordering constraints to improve stability on
1178 multi-core and multi-cpu systems
1179 - maximum voices and disk streams can now be altered at runtime
1180 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1181 - automatic stacktrace mechanism is now turned off by default and can
1182 be switched on by command line option "--stacktrace" (the automatic
1183 stacktrace mechanism seems to be broken on most systems at the moment)
1184 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1185 a pointer to the launched InstrumentEditor object
1186 - added optional 3rd party user data parameter for following
1187 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1188 InstrumentEditor::Launch(),
1189 InstrumentManager::LaunchInstrumentEditor()
1190 - theoretical fix: made SynchronizedConfig follow C++0x memory
1191 model more strictly
1192 - fixes for using large audio device buffers
1193 - Windows: add the installation directory to the DLL search path
1194 when loading an editor plugin (solves problems with VST and
1195 gigedit on systems with other GTK versions installed)
1196 - updated linuxsampler man page
1197
1198 * audio driver:
1199 - removed the nonsense audio channel constraint (which was hard coded to
1200 max. 100 audio channels) for most audio drivers
1201 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1202 opposed to the LSCP specs
1203 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1204 reflected the wrong value
1205 - fixed a memory management bug in ASIO driver
1206 - Makefile fix: JACK_CFLAGS wasn't used
1207 - JACK: use jack_client_open instead of the deprecated
1208 jack_client_new
1209 - added (experimental) CoreAudio driver
1210 - applied old fixes to the ASIO driver that were included in the
1211 previous binary release but accidentally never committed to CVS
1212 (fixes #117)
1213 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1214 win64)
1215 - VST: added support for sample rate and buffer size changes
1216 - VST: close editor (Fantasia) when the VST is removed
1217 - VST: avoid opening Fantasia more than once for each VST instance
1218 - VST: export main function as "main" on Linux too (fix for
1219 energyXT)
1220 - VST: changed number of output channels from one stereo to 16
1221 stereo
1222 - added channel routing, fxsends and midi maps to the settings
1223 stored in the plugin state
1224 - performance optimization of AudioChannel::MixTo() and
1225 AudioChannel::CopyTo() methods using GCC vector exensions
1226 (if available)
1227 - ASIO fixes: avoid initializing the device twice, avoid throwing
1228 exception when getting parameters from a disconnected device
1229
1230 * MIDI driver:
1231 - added JACK MIDI driver
1232 - dispatch bank select as ordinary CC as well, the user might seriously
1233 want to (mis)use it for some purpose ("fixed" in all current MIDI
1234 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1235 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1236 CoreMidi or AU
1237 - fixed mingw-w64 compilation error in MME driver
1238 - made program change handling in MIDI thread real-time safe by
1239 moving the logic to a non-RT thread
1240 - fixed minor memory leak in ALSA driver
1241
1242 * instruments database:
1243 - avoid time consuming samples scanning when adding instruments
1244 to the instruments database
1245 - added support for handling lost files in the instruments database
1246 - Implemented option for adding instruments in separate directories
1247 in the instruments database
1248 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1249 - work-around for missing fnmatch function on Windows to make
1250 instrument database compilable
1251 - added instrument database support on Windows
1252 works with both standalone mode and VST plugin.
1253 the instruments DB file is located in
1254 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1255 databases for each windows user
1256 if no DB is present it automatically creates the .linuxsampler subdir
1257 and then creates an empty DB
1258 - fixed recursive import, which was broken on Windows
1259
1260 * Gigasampler format engine:
1261 - fixed a memory leak that could happen when a channel was deleted
1262 while notes were playing
1263 - made it possible to load an instrument even if the audio thread
1264 isn't running
1265 - added partial support for the "Controller Triggered" MIDI rule,
1266 enough for piano gigs with pedal noise samples
1267 - minor fix: only mark FX sends as being modified if really the
1268 respective FX send MIDI controller was used
1269 - added support for GM global device volume SysEx message
1270 (can be selected at compile time to either apply globally to the
1271 whole sampler [default] or only to the sampler channels that are
1272 connected to the respective MIDI input port the SysEx message arrived
1273 on)
1274 - bugfix: notes triggered at position 0 in the audio buffer were
1275 sometimes wrongly killed in the same buffer, causing no sound to
1276 be played
1277 - added support for chromatic / drumkit mode Roland GS Sysex message
1278 which is usally used to switch a part between chromatic sounds and
1279 drumkit sounds (as opposed to their common default setting of MIDI
1280 part 10 being a drumkit part and all other ones chromatic parts), in
1281 LS however one can switch between the first 16 MIDI instrument maps
1282 defined for the sampler
1283 - made it possible to create multiple sample channels even if the
1284 audio thread isn't running
1285 - fixed crash when removing channel with active voices (#116)
1286 - bugfix: on sample reference changes (instrument editor), only
1287 un-cache the respective sample if it's really not used by any
1288 sampler engine anymore
1289 - re-cache samples in case they were changed by an instrument editor,
1290 e.g. when a sample was added while playing (#82)
1291 - fixed hanging notes which occured when note-off event had the exact
1292 same time stamp as the voice's note-on event and occured both in the
1293 same audio fragment cycle (fixes bug #112)
1294 - added support for the "fine tune" and "pitch bend range"
1295 instrument-level gig parameters
1296 - fixed minor artifacts in pitch bend handling
1297 - added support for GS Reset SysEx message
1298 - allow gig files to use unlimited downward pitch shifting
1299 - added a limit check for upward pitch shifting
1300 - bugfix: sometimes, when playing a note twice fast, the second
1301 note was silent
1302 - fixed crash happening when a pitch bend event arrived at the
1303 same time a new instrument was loading
1304
1305 * LSCP server:
1306 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1307 react on MIDI data arriving on certain sampler channels (so far only
1308 Note-On and Note-Off events are sent via this LSCP event)
1309 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1310 react on MIDI data arriving on certain MIDI input devices (so far only
1311 Note-On and Note-Off events are sent via this LSCP event)
1312 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1313 SET DB_INSTRUMENT FILE_PATH
1314 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1315 frontends to send MIDI messages to specific sampler channel
1316 - added two additional fields to GET FILE INSTRUMENT INFO command -
1317 KEY_BINDINGS and KEYSWITCH_BINDINGS
1318 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1319 was incorrect
1320 - Optimized the retrieval of the MIDI instrument mappings
1321 - added new LSCP command "SET VOICES" to globally alter the maximum
1322 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1323 be triggered respectively
1324 - added new LSCP command "SET STREAMS" to globally alter the maximum
1325 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1326 which will be triggered respectively
1327 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1328 a gigedit file dialog is opened)
1329 - close all connections when LSCPServer is deleted
1330 - hard close of all sockets on exit
1331 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1332 driver
1333
1334 * Bug fixes:
1335 - fixed a crash which occurs when removing a sampler channel waiting
1336 to start instrument loading after another channel
1337 - fixed a crash which occurs when removing a sampler channel with
1338 instrument loading in progress (bug #113)
1339 - fixed termination caused by uncaught exception when adding MIDI
1340 instrument with PERSISTENT load mode
1341 - fixed possible iterator invalidations when resetting the sampler
1342 - fixed memory leaks when issuing the following LSCP commands:
1343 GET AUDIO_OUTPUT_DRIVER INFO
1344 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1345 GET MIDI_INPUT_DRIVER INFO
1346 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1347 - fixed possible compilation error when sqlite is not present
1348 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1349 - fixed crash when changing the audio output device of a sampler
1350 channel with loaded instrument and start playing notes
1351 - fixed endless loop in Engine::SuspendAll() (bug #120)
1352 - fixed a low-level atomic load function that was broken on 64-bit
1353 PowerPC, which probably could cause crashes on that platform
1354 - fixed a memory management error which could cause a crash when a
1355 plugin was unloaded
1356 - bugfix: two private structs had the same name, which could cause
1357 problems if the linker chose the wrong constructor
1358 - fixed low-level ConditionServer usage bug that caused lockups on
1359 Windows
1360
1361
1362 Version 0.5.1 (6 December 2007)
1363
1364 * packaging changes:
1365 - added autoconf checks for pthread library
1366 - added autoconf check for pthread bug found on certain NPTL-enabled
1367 glibc versions (see Gentoo bug report #194076)
1368 - added autoconf checks for MS Windows
1369
1370 * general changes:
1371 - bugfix: the thread used by an editor plugin didn't die when the
1372 editor closed
1373 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1374 out all the space. operator--() did not apply size_mask after
1375 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1376 order to avoid problems with the _NonVolatileReader functions.
1377 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1378 GetWriteSpace(). Since this function is currently only used in
1379 the stream's qsort() compare function, it didn't trigger any
1380 bugs.
1381 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1382 24bit mode too. Faster method to read 24bit words on little
1383 endian machines (x86): replaced 3 byte reads + shifts with a 1
1384 unaligned 32bit read and shift
1385 - experimental support for MS Windows (MIDI input via MME, AUDIO
1386 output via ASIO)
1387 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1388 - support for monitoring the total number of active disk streams
1389 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1390 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1391
1392 * AUDIO driver:
1393 - added Windows ASIO low latency audio driver
1394
1395 * MIDI driver:
1396 - added MME Windows MIDI driver
1397
1398 * LSCP server:
1399 - added support for Windows style path / filenames, however with
1400 forward slash path separators instead of backslash
1401 (i.e. "C:/foo/bar.gig")
1402 - allow naughty liblscp to send non-string device parameters within
1403 apostrophes as well
1404 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1405 "LIST FILE INSTRUMENTS <file>" and
1406 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1407 about an arbitrary instrument file on the system where the sampler is
1408 running on
1409
1410 Version 0.5.0 (15 October 2007)
1411
1412 * packaging changes:
1413 - config.h is not going to be installed along with liblinuxsampler's
1414 API header files anymore
1415 - only the API relevant header (and source) files will be exported to
1416 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1417 - added completely new XCode project files for Mac OSX which is now
1418 capable to execute our autoconf environment, thus no need anymore
1419 to maintain the compile time configuration file (osx/version.h) for
1420 OSX manually (patch by Toshi Nagata)
1421 - fixed buggy boolean --enable-foo / --disable-foo configure script
1422 parameters
1423 - global.h now only covers global definitions that are needed for the
1424 C++ API header files, all implementation internal global definitions
1425 are now in global_private.h
1426 - atomic.h is not exposed to the C++ API anymore
1427 - no need to include config.h anymore for using LS's API header files
1428 - fixed warnings in API doc generation
1429
1430 * general changes:
1431 - replaced the old, confusing MIDI program change mechanism by a
1432 flexible MIDI instrument mapper which allows to map arbitrary
1433 (MIDI bank, MIDI program) pairs with arbitrary
1434 (engine type, instrument file, file index) triplets which will be
1435 loaded on the respective channel when such MIDI program change
1436 messages arrive, beside that, each entry allows to define a life-time
1437 strategy for the instrument, so the user can define whether the
1438 instrument should i.e. be permanently loaded (to be able to switch
1439 quickly among sounds) or i.e. loaded just on demand when the
1440 respective program change arrives (to safe RAM space), as well as a
1441 global volume factor for each entry, so the user can adjust the volume
1442 dynamic of his mapped instrument collection without having to modify
1443 the instrument files, also one can manage arbitrary amount of such
1444 MIDI instrument maps and assign each sampler channel individually
1445 a certain map, so that i.e. separation of normal instruments and
1446 drumkits is possible
1447 - new notification events for tracking changes to audio/MIDI devices,
1448 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1449 - sampler was limited to load max. 200 instruments in the background
1450 due to a constant size RingBuffer FIFO which is now replaced by a
1451 dynamic (unlimited) size std::list FIFO
1452 - added FX sends, these allow to route audio signals to arbitrary audio
1453 output channels for being processed by external effect processors
1454 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1455 controllers
1456 - global (sampler wide) volume can now be controlled at runtime
1457 - Implemented new, improved notification system
1458 - fixed compilation errors regarding OSX
1459 (patch by Toshi Nagata)
1460 - implemented instruments database
1461 - added support for escape sequences to the instruments database
1462 - added highly experimental support for on-the-fly instrument editing
1463 within the sampler's process (by using instrument editor plugins),
1464 you'll notice the new "Registered instrument editors:" message on
1465 startup, added a new LSCP command:
1466 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1467 to spawn a matching instrument editor for the instrument on the
1468 given sampler channel, the plugin path can be overridden at compile
1469 time with ./configure --enable-plugin-dir=/some/dir
1470 - added experimental code for synchronizing instrument editors hosted
1471 in the sampler's process to safely edit instruments while playing
1472 without a crash (hopefully) by either suspending single regions
1473 wherever possible or if unavoidable whole engine(s)
1474 - fixed several issues in fundamental "Thread" class: set scheduling
1475 policy and priority on thread level, set a minimum stack size for
1476 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1477 threads simply inherited properties of starting thread instead of
1478 setting their own policy and priority
1479 - minor fix in our automatic stack trace mechanism on crashes, the
1480 main process did not wait for the stack trace process to finish
1481 its output
1482 - fixed some minor memory leaks
1483 - reenabled assembly features support, at the moment only for
1484 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1485 - minor assembly fix in x86 features detection (don't use the PIC
1486 register, to avoid relocations in the text segment at runtime)
1487 - POSIX callback functions of Thread.h are hidden
1488
1489 * MIDI driver:
1490 - dispatch bank select (MSB and LSB) messages
1491
1492 * audio driver:
1493 - the ALSA audio output driver parameters now reflect the correct
1494 parameter value ranges for the respective selected sound card
1495 (patch by Till Wimmer, a bit fixed and extended)
1496
1497 * Gigasampler format engine:
1498 - if a filter is used and EG2 finishes before EG1, let the voice
1499 die when EG2 has finished (this fixes a problem with clicks and
1500 voice starvation for some gigs)
1501 - playback is no longer disabled during instrument loading
1502 - all notes playing on a channel that changes its instrument keep
1503 playing with the old instrument until they get a note off
1504 command
1505 - EG fix: a release value of zero could cause noises or crash
1506 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1507 - EG fine tuning: when attack is zero the EG starts at a level
1508 above max sustain level, which means that there is a decay phase
1509 even if sustain is 100%
1510 - more EG fixes: the level could sometimes go below zero and cause
1511 noises or crashes
1512 - minor fix of EGDecay (patch by Toshi Nagata)
1513 - fixed compiler error when --enable-override-filter-type was
1514 supplied to the configure script (fixes #46)
1515 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1516 instead of a fix value
1517 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1518 127 (solo mode) only kill voices if the respective mode really
1519 changed
1520
1521 * LSCP server:
1522 - fixed compile time error for old Bison versions
1523 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1524 - parser now supports extended ASCII character set
1525 (up to ASCII code 255, i.e. includes now umlauts and accents)
1526 - filename arguments in LSCP commands now allow to use escape
1527 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1528 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1529 code value like \xf2) (fixes bug #24)
1530 - the following LSCP commands now also support escape sequences for at
1531 least one of their text-based parameters (i.e. name, description):
1532 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1533 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1534 "SET DB_INSTRUMENT_DIRECTORY NAME",
1535 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1536 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1537 "FIND DB_INSTRUMENT_DIRECTORIES"
1538 - returns verbose syntax errors (line and column where syntax error
1539 occured, the unexpected character and the actually expected, possible
1540 character(s), the latter only if less than 5 possibilities)
1541 - made sure that LSCP syntax is not affected by gigedit locale
1542 settings
1543 - bugfix regarding strings parameter lists: all comma separated lists
1544 of strings were treated as being one string containing commas
1545 (fixes #57)
1546
1547 * Bug fixes:
1548 - fixed crash occurring on certain LSCP scripts (Bug 39)
1549 - another thread safety fix for lscp "load engine" and "set
1550 channel audio output device"
1551 - fixed a crash which occurs when reassigning the same engine
1552 on a sampler channel with connected MIDI device
1553 - fixed a crash which occurs when changing the number of ports of a MIDI
1554 device connected to a sampler channel to number less then or equal
1555 to the index of the port to which the sampler channel is connected.
1556 - The previous bindings were not been disconnected when altering
1557 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1558 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1559 - The active stream/voice count statistic was incorrect.
1560 - notification events were not been sent for some sampler
1561 channel changes
1562 - added default min and max values to restrict the number of allowed
1563 audio output channels and MIDI input ports
1564 - the connection to the PCM interface is now closed when destroying
1565 an audio output device
1566 - files with slash in their path or filename could not be loaded
1567
1568 * test cases:
1569 - updated and fixed (haven't been touched in a while)
1570
1571 Version 0.4.0 (24 November 2006)
1572
1573 * packaging changes:
1574 - changed deprecated copyright attribute to license; added ldconfig
1575 to post-(un)install steps; added devel package for liblinuxsampler;
1576 to linuxsampler.spec (RPM)
1577 - install necessary development header files for allowing 3rd party
1578 applications to link against liblinuxsampler
1579 - liblinuxsampler's API documentation can be generated with 'make docs'
1580 (Doxygen required)
1581 - added benchmark to automatically detect the best triangle LFO
1582 implementation (currently either an integer math solution or a
1583 di-harmonic approximation), automatic detection can be overriden
1584 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1585 configure script argument though (mandatory for cross-compilation)
1586 - do not automatically pick optimized gcc flags if the user already
1587 provided some on his own (as CXXFLAGS)
1588 - added compile time option to disable processing of All-Notes-Off MIDI
1589 messages
1590 - added compile time options to allow disabling the various audio and
1591 MIDI drivers
1592 - fixed automatic GCC CPU switch detection on PPC
1593 (patch by Ebrahim Mayat)
1594
1595 * Gigasampler format engine:
1596 - extensive synthesis optimization
1597 (reimplementation of EGs and LFO(s), removed synthesis parameter
1598 prerendering and the synthesis parameter matrix in general, splitting
1599 each audio fragment into subfragments now where each subfragment uses
1600 constant pitch and filter coefficients. The volume coefficient is
1601 linearly interpolated inside a subfragment, unless
1602 --disable-interpolate-volume is set.)
1603 - fine tuning of the EG modulation parameters
1604 - improved filter cutoff calculation by adding support for the
1605 following gig parameters: Cutoff freq (used when no cutoff
1606 controller is defined), Control invert, Minimum cutoff, Velocity
1607 curve and Velocity range. The keyboard tracking now scales
1608 cutoff frequency instead of resonance.
1609 - added support for gig parameter Resonance.
1610 - fixed bug in sysex handling (patch by Juan Linietsky)
1611 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1612 which can be overridden with --enable-global-attenuation
1613 - EG fixes: made the length of "attack hold" stage more
1614 accurate. Release stage can now start before attack stage
1615 ends. Cancel release didn't work when sustain was zero. Attack
1616 time now has a minimal value to prevent clicks.
1617 - fixed pitch changes larger than one octave
1618 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1619 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1620 all modes can be altered via standard GM messages, that is CC5 for
1621 altering portamento time, CC65 for enabling / disabling portamento
1622 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1623 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1624 parameter) and crossfade
1625 - added support for the "attenuation controller threshold" gig
1626 parameter
1627 - added smoothing of volume changes caused by control change
1628 messages
1629 - sample loop parameters are now taken from the DimensionRegion
1630 instead of the wave chunk
1631 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1632 not equal to a power of two
1633 - reimplementation of the filter algorithm. The new filter is more
1634 accurate and supports all gig filter types, including bandreject
1635 and lowpass turbo.
1636 - real support for 24 bit samples - samples are not truncated to
1637 16 bits anymore
1638 - support for aftertouch (channel pressure, not polyphonic
1639 aftertouch)
1640 - LFO1 behaviour fixed (dampening from max volume instead of
1641 amplifying from 0)
1642
1643 * LSCP server:
1644 - fixed application exit on broken pipe error (fixes bug #20)
1645 - fixed the notification messages delay due to lack of
1646 network activity (fixes bug #26)
1647 - fixed parser bug which occured on space(s) within device parameters
1648 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1649
1650 * audio driver:
1651 - added aRts audio output driver (by no means RT safe)
1652
1653 * MIDI driver:
1654 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1655 messages several times instead of once
1656 - API extension for MIDI drivers which already supply exact time stamps
1657 for events (i.e. for offline rendering based MIDI drivers)
1658 - added checks for bad MIDI data
1659
1660 * linuxsampler application:
1661 - show available sampler engine types on startup
1662
1663 * general changes:
1664 - support for muting sampler channels and solo mode of the same, two new
1665 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1666 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1667 introduced for this, the behavior is the same like on a mixer console
1668 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1669 --enable-process-muted-channels which can be used to enable the
1670 processing of muted channels.
1671 - support for sostenuto pedal
1672 - support for monitoring the total number of active voices
1673 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1674 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1675 - fixed some memory management errors
1676 - fixed some concurrency problems that could lead to crashes when
1677 LSCP commands were executed
1678 - fixed crash when instrument loading failed previously on the same
1679 sampler channel (fixes bug #36)
1680
1681 Version 0.3.3 (15 July 2005)
1682
1683 * packaging changes:
1684 - fixed compilation with gcc 4.0
1685
1686 * Gigasampler format engine:
1687 - LFO preprocessing was performed even though the respective LFO was
1688 disabled by the instrument patch (minor efficiency fix)
1689 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1690 for volume ramp downs in the same fragment (needed for current voice
1691 stealing implementation) then simply inform the user with a warning
1692 about possible click sounds and reduce the volume ramp down
1693 appropriately instead of cancelling the audio device connection
1694
1695 Version 0.3.2 (24 June 2005)
1696
1697 * packaging changes:
1698 - updated autotools build files to compile on OS X
1699 (conditional compilation of CoreMIDI and MidiShare drivers)
1700 - hand-crafted assembly optimization code can be disabled with
1701 './configure --disable-asm' (definitely not recommended)
1702 - fixed 'make dist' rule to include all necessary files
1703 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1704 (due to 'dist-bzip2' automake option)
1705
1706 * Gigasampler format engine:
1707 - support for the gig parameters for "release velocity response" curves
1708 - fine tuning of the EGADSR envelope
1709 - volume of release triggered samples now depends on note-on velocity,
1710 note length and gig parameter "release trigger decay" instead of
1711 note-off velocity.
1712 - revised voice stealing
1713 (fixes crash and endless loop caused by voice stealing)
1714 - don't reset scale tuning on instrument or audio output device change
1715 - handle key group conflicts right at the beginning of each fragment
1716 instead of when the respective voice is actually launched
1717 (fixes undefined behavior if stolen voices belonged to a key group -
1718 this case was followed by a "killed voice survived" error message)
1719 - fixed minor issue with null/silence samples
1720 (those stole voices even though they don't need a voice at all which
1721 resulted in "voice stealing didn't work out" messages)
1722 - don't reset volume, pan, pitch and MIDI controller values on
1723 instrument or audio output device change
1724
1725 * LSCP server:
1726 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1727 - fixed LSCP event "CHANNEL_INFO" notification
1728 (e.g. did not notify on volume changes or MIDI program change events)
1729
1730 * linuxsampler application:
1731 - added command line parameters --lscp-addr and --lscp-port to override
1732 default IP address and port of LSCP server
1733
1734 Version 0.3.1 (24 May 2005)
1735
1736 * initial release
