File size: 97730 byte(s)
Tests: Added thorough NKSP test cases for variable declarations.

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

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

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

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

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

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

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

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

628 - Mac OS X: Makefile fix for the install-strip target
629 - fixed compilation with gcc 4.7
630 - fixed configure script error with old autoconf versions
631 - lsatomic.h: use gcc provided atomic functions if building with
632 gcc 4.7 and C++11
633 - modernized configure script
634 - fixed linkage error when building with
635 LDFLAGS="-Wl,--no-undefined" (#190)
636 - fixed compilation with Clang 3.2
637 - removed usage of deprecated Automake variable INCLUDES
638 - fixed building with C++11

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

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

727 key
728 - bugfix: pitch LFO controller "internal+aftertouch" was broken
729 - bugfix: filter keyboard tracking was broken
730 - filter performance fix (an unnecessary copy was made of the
731 filter parameters in each sub fragment)
732 - handle special case when pan parameter in gig file has max or
733 min value
734 - Exclusive Groups: don't ever stop voices of the same note,
735 doesn't sound naturally with a drumkit
736 - fixed EG1 modulation when attack or release is zero
737 - Fixed support for 'aftertouch' attenuation controller.
738 - Fixed crash that happened with velocity split sounds under certain
739 conditions (see also previous commit on libgig).
740 - fixed behaviour of filter LFO
741
742 * SFZ format engine:

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

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

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

1108 - bugfix: playing a note while changing the instrument could cause
1109 a crash, or give "Handing back unknown region" error messages
1110 - bugfix: calling SET VOICES (which Fantasia does on start and
1111 refresh) could cause instruments to be unloaded
1112 - Mac OS X: fixed name collision of enum in EffectControl and
1113 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp

1144 crashes and noise on such transitions).
1145 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1146 (fixes #208)
1147 - Fixed bug in LSCP grammar definition which caused a statement like
1148 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1149 practically irrelevant, however it caused problems with the new LSCP
1150 shell's auto completion feature).
1151 - Fixed MIDI program change messages being ignored if quickly executed
1152 after each other (fixes #231).
1153
1154 Version 1.0.0 (31 July 2009)
1155
1156 * packaging changes:
1157 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1169 directory of liblinuxsampler dll (look in the same directory and one
1170 directory above)
1171 - configure script fix: removed unconditional use of SSE
1172 - fixed building with sqlite installed in a non-standard directory
1173 - when cross-compiling, don't try to create instruments.db

1179 (fixes bug #70, patch by Ronald Baljeu)
1180 - fixed endless loop which occured when loading an instrument editor
1181 plugin DLL on Windows systems failed
1182 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1183 - optimized the SynchronizedConfig class so it doesn't wait
1184 unnecessarily long after an update

1186 events (e.g. to highlight the pressed keys on the virtual keyboard
1187 of gigedit)
1188 - added support for triggering notes by instrument editors (see above)
1189 - be verbose on DLL load errors (on Linux)
1190 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1192 implementation, which is usually faster)
1193 - fixes for audio drivers with varying buffer sizes
1194 - experimental support for running LinuxSampler as a DSSI, LV2 and
1195 VST plugin

1201 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1202 - automatic stacktrace mechanism is now turned off by default and can
1203 be switched on by command line option "--stacktrace" (the automatic
1204 stacktrace mechanism seems to be broken on most systems at the moment)
1205 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1206 a pointer to the launched InstrumentEditor object
1207 - added optional 3rd party user data parameter for following
1208 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1209 InstrumentEditor::Launch(),

1211 - theoretical fix: made SynchronizedConfig follow C++0x memory
1212 model more strictly
1213 - fixes for using large audio device buffers
1214 - Windows: add the installation directory to the DLL search path
1215 when loading an editor plugin (solves problems with VST and

1220 - removed the nonsense audio channel constraint (which was hard coded to
1221 max. 100 audio channels) for most audio drivers
1222 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1223 opposed to the LSCP specs
1224 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1225 reflected the wrong value
1226 - fixed a memory management bug in ASIO driver
1227 - Makefile fix: JACK_CFLAGS wasn't used
1228 - JACK: use jack_client_open instead of the deprecated

1235 win64)
1236 - VST: added support for sample rate and buffer size changes
1237 - VST: close editor (Fantasia) when the VST is removed
1238 - VST: avoid opening Fantasia more than once for each VST instance

1240 energyXT)
1241 - VST: changed number of output channels from one stereo to 16
1242 stereo
1243 - added channel routing, fxsends and midi maps to the settings
1244 stored in the plugin state
1245 - performance optimization of AudioChannel::MixTo() and
1246 AudioChannel::CopyTo() methods using GCC vector exensions
1247 (if available)

1249 exception when getting parameters from a disconnected device
1250
1251 * MIDI driver:
1252 - added JACK MIDI driver
1253 - dispatch bank select as ordinary CC as well, the user might seriously
1254 want to (mis)use it for some purpose ("fixed" in all current MIDI
1255 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1256 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1257 CoreMidi or AU
1258 - fixed mingw-w64 compilation error in MME driver
1259 - made program change handling in MIDI thread real-time safe by
1260 moving the logic to a non-RT thread

1271 instrument database compilable
1272 - added instrument database support on Windows
1273 works with both standalone mode and VST plugin.
1274 the instruments DB file is located in
1275 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1276 databases for each windows user
1277 if no DB is present it automatically creates the .linuxsampler subdir
1278 and then creates an empty DB
1279 - fixed recursive import, which was broken on Windows
1280
1281 * Gigasampler format engine:
1282 - fixed a memory leak that could happen when a channel was deleted
1283 while notes were playing
1284 - made it possible to load an instrument even if the audio thread
1285 isn't running
1286 - added partial support for the "Controller Triggered" MIDI rule,
1287 enough for piano gigs with pedal noise samples
1288 - minor fix: only mark FX sends as being modified if really the
1289 respective FX send MIDI controller was used
1290 - added support for GM global device volume SysEx message
1291 (can be selected at compile time to either apply globally to the
1292 whole sampler [default] or only to the sampler channels that are
1293 connected to the respective MIDI input port the SysEx message arrived
1294 on)
1295 - bugfix: notes triggered at position 0 in the audio buffer were
1296 sometimes wrongly killed in the same buffer, causing no sound to
1297 be played
1298 - added support for chromatic / drumkit mode Roland GS Sysex message
1299 which is usally used to switch a part between chromatic sounds and
1300 drumkit sounds (as opposed to their common default setting of MIDI
1301 part 10 being a drumkit part and all other ones chromatic parts), in
1302 LS however one can switch between the first 16 MIDI instrument maps
1303 defined for the sampler
1304 - made it possible to create multiple sample channels even if the
1305 audio thread isn't running
1306 - fixed crash when removing channel with active voices (#116)
1307 - bugfix: on sample reference changes (instrument editor), only
1308 un-cache the respective sample if it's really not used by any
1309 sampler engine anymore
1310 - re-cache samples in case they were changed by an instrument editor,
1311 e.g. when a sample was added while playing (#82)
1312 - fixed hanging notes which occured when note-off event had the exact
1313 same time stamp as the voice's note-on event and occured both in the
1314 same audio fragment cycle (fixes bug #112)
1315 - added support for the "fine tune" and "pitch bend range"
1316 instrument-level gig parameters
1317 - fixed minor artifacts in pitch bend handling
1318 - added support for GS Reset SysEx message
1319 - allow gig files to use unlimited downward pitch shifting
1320 - added a limit check for upward pitch shifting
1321 - bugfix: sometimes, when playing a note twice fast, the second
1322 note was silent
1323 - fixed crash happening when a pitch bend event arrived at the
1324 same time a new instrument was loading
1325
1326 * LSCP server:
1327 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1328 react on MIDI data arriving on certain sampler channels (so far only
1329 Note-On and Note-Off events are sent via this LSCP event)
1330 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1331 react on MIDI data arriving on certain MIDI input devices (so far only
1332 Note-On and Note-Off events are sent via this LSCP event)
1333 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1334 SET DB_INSTRUMENT FILE_PATH
1335 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1336 frontends to send MIDI messages to specific sampler channel
1337 - added two additional fields to GET FILE INSTRUMENT INFO command -
1338 KEY_BINDINGS and KEYSWITCH_BINDINGS
1339 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1340 was incorrect
1341 - Optimized the retrieval of the MIDI instrument mappings
1342 - added new LSCP command "SET VOICES" to globally alter the maximum
1343 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1344 be triggered respectively
1345 - added new LSCP command "SET STREAMS" to globally alter the maximum
1346 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1347 which will be triggered respectively
1348 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1349 a gigedit file dialog is opened)
1350 - close all connections when LSCPServer is deleted
1351 - hard close of all sockets on exit
1352 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1353 driver
1354
1355 * Bug fixes:
1356 - fixed a crash which occurs when removing a sampler channel waiting
1357 to start instrument loading after another channel
1358 - fixed a crash which occurs when removing a sampler channel with
1359 instrument loading in progress (bug #113)
1360 - fixed termination caused by uncaught exception when adding MIDI
1361 instrument with PERSISTENT load mode
1362 - fixed possible iterator invalidations when resetting the sampler
1363 - fixed memory leaks when issuing the following LSCP commands:
1364 GET AUDIO_OUTPUT_DRIVER INFO
1365 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1366 GET MIDI_INPUT_DRIVER INFO
1367 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1368 - fixed possible compilation error when sqlite is not present
1369 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1370 - fixed crash when changing the audio output device of a sampler
1371 channel with loaded instrument and start playing notes
1372 - fixed endless loop in Engine::SuspendAll() (bug #120)
1373 - fixed a low-level atomic load function that was broken on 64-bit
1374 PowerPC, which probably could cause crashes on that platform
1375 - fixed a memory management error which could cause a crash when a
1376 plugin was unloaded
1377 - bugfix: two private structs had the same name, which could cause
1378 problems if the linker chose the wrong constructor
1379 - fixed low-level ConditionServer usage bug that caused lockups on
1380 Windows
1381
1382
1383 Version 0.5.1 (6 December 2007)
1384
1385 * packaging changes:
1386 - added autoconf checks for pthread library
1387 - added autoconf check for pthread bug found on certain NPTL-enabled
1388 glibc versions (see Gentoo bug report #194076)
1389 - added autoconf checks for MS Windows
1390
1391 * general changes:
1392 - bugfix: the thread used by an editor plugin didn't die when the
1393 editor closed
1394 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1395 out all the space. operator--() did not apply size_mask after
1396 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1397 order to avoid problems with the _NonVolatileReader functions.
1398 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1399 GetWriteSpace(). Since this function is currently only used in
1400 the stream's qsort() compare function, it didn't trigger any
1401 bugs.
1402 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1403 24bit mode too. Faster method to read 24bit words on little
1404 endian machines (x86): replaced 3 byte reads + shifts with a 1
1405 unaligned 32bit read and shift
1406 - experimental support for MS Windows (MIDI input via MME, AUDIO
1407 output via ASIO)
1408 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1409 - support for monitoring the total number of active disk streams
1410 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1411 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1412
1413 * AUDIO driver:
1414 - added Windows ASIO low latency audio driver
1415
1416 * MIDI driver:
1417 - added MME Windows MIDI driver
1418
1419 * LSCP server:
1420 - added support for Windows style path / filenames, however with
1421 forward slash path separators instead of backslash
1422 (i.e. "C:/foo/bar.gig")
1423 - allow naughty liblscp to send non-string device parameters within
1424 apostrophes as well
1425 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1426 "LIST FILE INSTRUMENTS <file>" and
1427 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1428 about an arbitrary instrument file on the system where the sampler is
1429 running on
1430
1431 Version 0.5.0 (15 October 2007)
1432
1433 * packaging changes:
1434 - config.h is not going to be installed along with liblinuxsampler's
1435 API header files anymore
1436 - only the API relevant header (and source) files will be exported to
1437 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1438 - added completely new XCode project files for Mac OSX which is now
1439 capable to execute our autoconf environment, thus no need anymore
1440 to maintain the compile time configuration file (osx/version.h) for
1441 OSX manually (patch by Toshi Nagata)
1442 - fixed buggy boolean --enable-foo / --disable-foo configure script
1443 parameters
1444 - global.h now only covers global definitions that are needed for the
1445 C++ API header files, all implementation internal global definitions
1446 are now in global_private.h
1447 - atomic.h is not exposed to the C++ API anymore
1448 - no need to include config.h anymore for using LS's API header files
1449 - fixed warnings in API doc generation
1450
1451 * general changes:
1452 - replaced the old, confusing MIDI program change mechanism by a
1453 flexible MIDI instrument mapper which allows to map arbitrary
1454 (MIDI bank, MIDI program) pairs with arbitrary
1455 (engine type, instrument file, file index) triplets which will be
1456 loaded on the respective channel when such MIDI program change
1457 messages arrive, beside that, each entry allows to define a life-time
1458 strategy for the instrument, so the user can define whether the
1459 instrument should i.e. be permanently loaded (to be able to switch
1460 quickly among sounds) or i.e. loaded just on demand when the
1461 respective program change arrives (to safe RAM space), as well as a
1462 global volume factor for each entry, so the user can adjust the volume
1463 dynamic of his mapped instrument collection without having to modify
1464 the instrument files, also one can manage arbitrary amount of such
1465 MIDI instrument maps and assign each sampler channel individually
1466 a certain map, so that i.e. separation of normal instruments and
1467 drumkits is possible
1468 - new notification events for tracking changes to audio/MIDI devices,
1469 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1470 - sampler was limited to load max. 200 instruments in the background
1471 due to a constant size RingBuffer FIFO which is now replaced by a
1472 dynamic (unlimited) size std::list FIFO
1473 - added FX sends, these allow to route audio signals to arbitrary audio
1474 output channels for being processed by external effect processors
1475 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1476 controllers
1477 - global (sampler wide) volume can now be controlled at runtime
1478 - Implemented new, improved notification system
1479 - fixed compilation errors regarding OSX
1480 (patch by Toshi Nagata)
1481 - implemented instruments database
1482 - added support for escape sequences to the instruments database
1483 - added highly experimental support for on-the-fly instrument editing
1484 within the sampler's process (by using instrument editor plugins),
1485 you'll notice the new "Registered instrument editors:" message on
1486 startup, added a new LSCP command:
1487 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1488 to spawn a matching instrument editor for the instrument on the
1489 given sampler channel, the plugin path can be overridden at compile
1490 time with ./configure --enable-plugin-dir=/some/dir
1491 - added experimental code for synchronizing instrument editors hosted
1492 in the sampler's process to safely edit instruments while playing
1493 without a crash (hopefully) by either suspending single regions
1494 wherever possible or if unavoidable whole engine(s)
1495 - fixed several issues in fundamental "Thread" class: set scheduling
1496 policy and priority on thread level, set a minimum stack size for
1497 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1498 threads simply inherited properties of starting thread instead of
1499 setting their own policy and priority
1500 - minor fix in our automatic stack trace mechanism on crashes, the
1501 main process did not wait for the stack trace process to finish
1502 its output
1503 - fixed some minor memory leaks
1504 - reenabled assembly features support, at the moment only for
1505 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1506 - minor assembly fix in x86 features detection (don't use the PIC
1507 register, to avoid relocations in the text segment at runtime)
1508 - POSIX callback functions of Thread.h are hidden
1509
1510 * MIDI driver:
1511 - dispatch bank select (MSB and LSB) messages
1512
1513 * audio driver:
1514 - the ALSA audio output driver parameters now reflect the correct
1515 parameter value ranges for the respective selected sound card
1516 (patch by Till Wimmer, a bit fixed and extended)
1517
1518 * Gigasampler format engine:
1519 - if a filter is used and EG2 finishes before EG1, let the voice
1520 die when EG2 has finished (this fixes a problem with clicks and
1521 voice starvation for some gigs)
1522 - playback is no longer disabled during instrument loading
1523 - all notes playing on a channel that changes its instrument keep
1524 playing with the old instrument until they get a note off
1525 command
1526 - EG fix: a release value of zero could cause noises or crash
1527 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1528 - EG fine tuning: when attack is zero the EG starts at a level
1529 above max sustain level, which means that there is a decay phase
1530 even if sustain is 100%
1531 - more EG fixes: the level could sometimes go below zero and cause
1532 noises or crashes
1533 - minor fix of EGDecay (patch by Toshi Nagata)
1534 - fixed compiler error when --enable-override-filter-type was
1535 supplied to the configure script (fixes #46)
1536 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1537 instead of a fix value
1538 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1539 127 (solo mode) only kill voices if the respective mode really
1540 changed
1541
1542 * LSCP server:
1543 - fixed compile time error for old Bison versions
1544 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1545 - parser now supports extended ASCII character set
1546 (up to ASCII code 255, i.e. includes now umlauts and accents)
1547 - filename arguments in LSCP commands now allow to use escape
1548 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1549 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1550 code value like \xf2) (fixes bug #24)
1551 - the following LSCP commands now also support escape sequences for at
1552 least one of their text-based parameters (i.e. name, description):
1553 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1554 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1555 "SET DB_INSTRUMENT_DIRECTORY NAME",
1556 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1557 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1558 "FIND DB_INSTRUMENT_DIRECTORIES"
1559 - returns verbose syntax errors (line and column where syntax error
1560 occured, the unexpected character and the actually expected, possible
1561 character(s), the latter only if less than 5 possibilities)
1562 - made sure that LSCP syntax is not affected by gigedit locale
1563 settings
1564 - bugfix regarding strings parameter lists: all comma separated lists
1565 of strings were treated as being one string containing commas
1566 (fixes #57)
1567
1568 * Bug fixes:
1569 - fixed crash occurring on certain LSCP scripts (Bug 39)
1570 - another thread safety fix for lscp "load engine" and "set
1571 channel audio output device"
1572 - fixed a crash which occurs when reassigning the same engine
1573 on a sampler channel with connected MIDI device
1574 - fixed a crash which occurs when changing the number of ports of a MIDI
1575 device connected to a sampler channel to number less then or equal
1576 to the index of the port to which the sampler channel is connected.
1577 - The previous bindings were not been disconnected when altering
1578 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1579 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1580 - The active stream/voice count statistic was incorrect.
1581 - notification events were not been sent for some sampler
1582 channel changes
1583 - added default min and max values to restrict the number of allowed
1584 audio output channels and MIDI input ports
1585 - the connection to the PCM interface is now closed when destroying
1586 an audio output device
1587 - files with slash in their path or filename could not be loaded
1588
1589 * test cases:
1590 - updated and fixed (haven't been touched in a while)
1591
1592 Version 0.4.0 (24 November 2006)
1593
1594 * packaging changes:
1595 - changed deprecated copyright attribute to license; added ldconfig
1596 to post-(un)install steps; added devel package for liblinuxsampler;
1597 to linuxsampler.spec (RPM)
1598 - install necessary development header files for allowing 3rd party
1599 applications to link against liblinuxsampler
1600 - liblinuxsampler's API documentation can be generated with 'make docs'
1601 (Doxygen required)
1602 - added benchmark to automatically detect the best triangle LFO
1603 implementation (currently either an integer math solution or a
1604 di-harmonic approximation), automatic detection can be overriden
1605 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1606 configure script argument though (mandatory for cross-compilation)
1607 - do not automatically pick optimized gcc flags if the user already
1608 provided some on his own (as CXXFLAGS)
1609 - added compile time option to disable processing of All-Notes-Off MIDI
1610 messages
1611 - added compile time options to allow disabling the various audio and
1612 MIDI drivers
1613 - fixed automatic GCC CPU switch detection on PPC
1614 (patch by Ebrahim Mayat)
1615
1616 * Gigasampler format engine:
1617 - extensive synthesis optimization
1618 (reimplementation of EGs and LFO(s), removed synthesis parameter
1619 prerendering and the synthesis parameter matrix in general, splitting
1620 each audio fragment into subfragments now where each subfragment uses
1621 constant pitch and filter coefficients. The volume coefficient is
1622 linearly interpolated inside a subfragment, unless
1623 --disable-interpolate-volume is set.)
1624 - fine tuning of the EG modulation parameters
1625 - improved filter cutoff calculation by adding support for the
1626 following gig parameters: Cutoff freq (used when no cutoff
1627 controller is defined), Control invert, Minimum cutoff, Velocity
1628 curve and Velocity range. The keyboard tracking now scales
1629 cutoff frequency instead of resonance.
1630 - added support for gig parameter Resonance.
1631 - fixed bug in sysex handling (patch by Juan Linietsky)
1632 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1633 which can be overridden with --enable-global-attenuation
1634 - EG fixes: made the length of "attack hold" stage more
1635 accurate. Release stage can now start before attack stage
1636 ends. Cancel release didn't work when sustain was zero. Attack
1637 time now has a minimal value to prevent clicks.
1638 - fixed pitch changes larger than one octave
1639 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1640 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1641 all modes can be altered via standard GM messages, that is CC5 for
1642 altering portamento time, CC65 for enabling / disabling portamento
1643 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1644 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1645 parameter) and crossfade
1646 - added support for the "attenuation controller threshold" gig
1647 parameter
1648 - added smoothing of volume changes caused by control change
1649 messages
1650 - sample loop parameters are now taken from the DimensionRegion
1651 instead of the wave chunk
1652 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1653 not equal to a power of two
1654 - reimplementation of the filter algorithm. The new filter is more
1655 accurate and supports all gig filter types, including bandreject
1656 and lowpass turbo.
1657 - real support for 24 bit samples - samples are not truncated to
1658 16 bits anymore
1659 - support for aftertouch (channel pressure, not polyphonic
1660 aftertouch)
1661 - LFO1 behaviour fixed (dampening from max volume instead of
1662 amplifying from 0)
1663
1664 * LSCP server:
1665 - fixed application exit on broken pipe error (fixes bug #20)
1666 - fixed the notification messages delay due to lack of
1667 network activity (fixes bug #26)
1668 - fixed parser bug which occured on space(s) within device parameters
1669 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1670
1671 * audio driver:
1672 - added aRts audio output driver (by no means RT safe)
1673
1674 * MIDI driver:
1675 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1676 messages several times instead of once
1677 - API extension for MIDI drivers which already supply exact time stamps
1678 for events (i.e. for offline rendering based MIDI drivers)
1679 - added checks for bad MIDI data
1680
1681 * linuxsampler application:
1682 - show available sampler engine types on startup
1683
1684 * general changes:
1685 - support for muting sampler channels and solo mode of the same, two new
1686 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1687 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1688 introduced for this, the behavior is the same like on a mixer console
1689 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1690 --enable-process-muted-channels which can be used to enable the
1691 processing of muted channels.
1692 - support for sostenuto pedal
1693 - support for monitoring the total number of active voices
1694 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1695 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1696 - fixed some memory management errors
1697 - fixed some concurrency problems that could lead to crashes when
1698 LSCP commands were executed
1699 - fixed crash when instrument loading failed previously on the same
1700 sampler channel (fixes bug #36)
1701
1702 Version 0.3.3 (15 July 2005)
1703
1704 * packaging changes:
1705 - fixed compilation with gcc 4.0
1706
1707 * Gigasampler format engine:
1708 - LFO preprocessing was performed even though the respective LFO was
1709 disabled by the instrument patch (minor efficiency fix)
1710 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1711 for volume ramp downs in the same fragment (needed for current voice
1712 stealing implementation) then simply inform the user with a warning
1713 about possible click sounds and reduce the volume ramp down
1714 appropriately instead of cancelling the audio device connection
1715
1716 Version 0.3.2 (24 June 2005)
1717
1718 * packaging changes:
1719 - updated autotools build files to compile on OS X
1720 (conditional compilation of CoreMIDI and MidiShare drivers)
1721 - hand-crafted assembly optimization code can be disabled with
1722 './configure --disable-asm' (definitely not recommended)
1723 - fixed 'make dist' rule to include all necessary files
1724 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1725 (due to 'dist-bzip2' automake option)
1726
1727 * Gigasampler format engine:
1728 - support for the gig parameters for "release velocity response" curves
1729 - fine tuning of the EGADSR envelope
1730 - volume of release triggered samples now depends on note-on velocity,
1731 note length and gig parameter "release trigger decay" instead of
1732 note-off velocity.
1733 - revised voice stealing
1734 (fixes crash and endless loop caused by voice stealing)
1735 - don't reset scale tuning on instrument or audio output device change
1736 - handle key group conflicts right at the beginning of each fragment
1737 instead of when the respective voice is actually launched
1738 (fixes undefined behavior if stolen voices belonged to a key group -
