Revision 3726 - (show annotations) (download)
Sun Jan 26 15:30:52 2020 UTC (4 years, 2 months ago) by schoenebeck
File size: 97666 byte(s)
Fixed potential crash with high pitch at end of RAM playback:

* AbstractVoice: variable 'cachedsamples' is already in sample points,
  so the previous division by amount of audio channels, allowed RAM
  playback to exceed beyond the amount of samples being cached.

* Bumped version (2.1.1.svn43).

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
273 * GigaStudio/Gigasampler format engine:
274 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
275 behaviour for start_level_mid.
276 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
277 level (see discussion "GigaStudio LFO compatibility" on mailing list
278 from 2019-09-26 for details).
279 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
280 see discussion "GigaStudio LFO compatibility" on mailing list from
281 2019-09-26 for details).
282 - Format extension: Added support for different LFO wave forms (currently
283 either sine [default], triangle, saw or square).
284 - Format extension: Added support for LFO phase displacement (0��..360��).
285 - Format extension: Added support for flipping LFO polarity on LFO 3
286 (in the original gig format this was only available for LFO 1 and LFO 2).
287 - Format extension: Support for additional filter types:
288 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
289 bandreject 2-pole.
290 - Fixd potential crash with polynomial interpolator and max. pitch.
291 - If minimum cutoff is defined, remap cutoff controller CC values to really
292 span the entire possible cutoff range (and avoiding a dead controller
293 zone).
294
295 * SFZ format engine:
296 - Fixed support for regions with loccN/hiccN conditions on more than one
297 MIDI controller.
298
299 * Benchmarks:
300 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
301 algorithm (since result of 2nd run was not accumulated).
302 - Added benchmark for saw wave (benchmarks/saw.cpp).
303 - Added benchmark for sine wave (benchmarks/sine.cpp).
304 - Added benchmark for square wave (benchmarks/square.cpp).
305 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
306 which are large enough on modern systems.
307
308 Version 2.1.1 (27 Jul 2019)
309
310 * Real-time instrument scripts:
311 - Fixed behavior of built-in NKSP functions change_sustain(),
312 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
313 and change_cutoff_release().
314
315 * general changes:
316 - Only play release trigger samples on sustain pedal up if this behaviour
317 was explicitly requested by the instrument (otherwise only on note-off).
318 - Fixed compiler warnings.
319 - Fixed compilation error when cross-compiling to Mac.
320 - FX Sends: Provide more useful error messages on routing problems
321 (see bug #169).
322 - LSCP doc: Be more clear describing the two distinct approaches
323 of using external vs. internal effects (see bug #169).
324 - "optional" class: Fixed comparison operators.
325
326 * Gigasampler/GigaStudio format engine:
327 - Format extension: If requested by instrument then don't play release
328 trigger sample on note-off events.
329
330 * SFZ format engine:
331 - Fixed memory leak when releasing samples
332 (fixes bug #307, patch by Jacek Roszkowski)
333 - Fixed potential crash when a sample is shared by more than one region
334 (fixes bug #308, patch by Jacek Roszkowski).
335 - Opcode 'sample': Added support for built-in sample '*silence'
336 (fixes bug #310, patch by Jacek Roszkowski).
337
338 Version 2.1.0 (25 Nov 2017)
339
340 * SFZ format engine:
341 - added support for <global>, <master> and #define (patch by Alby M)
342 - Removed code duplication in SFZ file loading code.
343 - Added support for sfz extension opcode 'script' which may be used to
344 load real-time instrument script file (NKSP script language).
345 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
346 - Fixed unintended volume fade-in of voices under certain conditions.
347 - sfz parser: allow missing space between header and opcode
348
349 * Gigasampler/GigaStudio format engine:
350 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
351 cutoff settings.
352 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
353 all if an up-pitch of more than 40 semi tones was requested (I don't
354 think there is any stock gig sound that requires this behavior to
355 resemble its original sound).
356 - Added support for controlling whether the individual EGADSR stages may
357 be aborted (as LinuxSampler extension to the original GigaStudio 4
358 format).
359
360 * general changes:
361 - fixed printf type errors (mostly in debug messages)
362 - use unique_ptr instead of auto_ptr when building with C++11
363 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
364 allowing to sort data efficiently in real-time safe manner.
365 - RTList class: added methods for moving/inserting elements to arbitrary
366 position within a list.
367 - RTList class: added method fromPtr() for creating an Iterator object from
368 a raw element pointer.
369 - Attempt to partly fix resetting engine channels vs. resetting engine, an
370 overall cleanup of the Reset*(), ConnectAudioDevice(),
371 DisconnectAudioDevice() API methods would still be desirable though,
372 because the current situation is still inconsistent and error prone.
373 - Active voices are now internally grouped to "Note" objects, instead of
374 being directly assigned to a keyboard key. This allows more fine graded
375 processing of voices, which is i.e. required for certain instrument
376 script features.
377 - Fix: Release trigger voices were not spawned on sustain pedal up
378 (CC #64) events.
379 - Fix: Release trigger voices can now also distinguish correctly between
380 note-off and sustain pedal up events.
381 - All engines: Increased ramp speed of volume smoother and pan smoother
382 (while slow rate of crossfade smoother is preserved) to allow quick
383 volume and pan changes by instrument scripts for instance.
384 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
385 properly and thus were ignored for certain uses.
386 - Added new C++ API method
387 VirtualMidiDevice::SendChannelPressureToSampler().
388 - windows, 32-bit: fixed potential crashes by making sure the stack in
389 sub threads is 16-byte aligned
390 - fixed numerous compiler warnings
391 - Fixed invalid (note-on) event ID being assigned to new Note objects.
392 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
393 fixes potential undefined behavior.
394 - Fixed Note object leak when triggering notes on keys which did not
395 have a valid sample mapped (fixes bug #252).
396 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
397 - linuxsampler binary fix: option --create-instruments-db ignored
398 subsequent optional argument due to glibc's implementation oddity
399 which expects a "=" sign, but no space between them.
400
401 * packaging changes:
402 - removed unnecessary dependency to libuuid
403 (originated by libgig's usage of it)
404 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
405 auto detect whether it (sh/c)ould output its messages in color.
406 - Debian: Fixed packaging error about invalid "Source-Version"
407 substitution variable.
408 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
409 - Debian: Added build dependency to libsqlite3-dev for building
410 linuxsampler with instruments DB support.
411
412 * Real-time instrument scripts:
413 - Implemented scheduler for delayed MIDI events and for suspended scripts.
414 - Built-in script function "wait()": implemented support for function's
415 "duration-us" argument, thus scripts using this function are now
416 correctly resumed after the requested amount of microseconds.
417 - Built-in script function "play_note()": implemented support for
418 function's "duration-us" argument, thus notes triggered with this
419 argument are now correctly released after the requested amount of
420 microseconds.
421 - Fix: script events were not cleared when engine channel was reset,
422 potentially causing undefined behavior.
423 - Fixed crash which happened when trying to reference an undeclared
424 variable.
425 - Built-in script function "play_note()": Added support for passing

429 - Added new API method ScriptVM::syntaxHighlighting() which provides
430 a convenient syntax highlighting backend for external instrument
431 script editor applications.

433 - Extended parser issues to provide not only first line and first
434 column, but also last line and last column of issue (thus marking
435 the precise span of the issue within the source code).

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

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

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

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

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

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

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

627 - Mac OS X: Makefile fix for the install-strip target
628 - fixed compilation with gcc 4.7
629 - fixed configure script error with old autoconf versions

632 - modernized configure script
633 - fixed linkage error when building with
634 LDFLAGS="-Wl,--no-undefined" (#190)

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

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

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

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

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

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

1143 crashes and noise on such transitions).
1144 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1145 (fixes #208)
1146 - Fixed bug in LSCP grammar definition which caused a statement like
1147 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1148 practically irrelevant, however it caused problems with the new LSCP
1149 shell's auto completion feature).
1150 - Fixed MIDI program change messages being ignored if quickly executed
1151 after each other (fixes #231).
1152
1153 Version 1.0.0 (31 July 2009)
1154
1155 * packaging changes:
1156 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1168 directory of liblinuxsampler dll (look in the same directory and one
1169 directory above)
1170 - configure script fix: removed unconditional use of SSE
1171 - fixed building with sqlite installed in a non-standard directory
1172 - when cross-compiling, don't try to create instruments.db

1178 (fixes bug #70, patch by Ronald Baljeu)
1179 - fixed endless loop which occured when loading an instrument editor
1180 plugin DLL on Windows systems failed
1181 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1182 - optimized the SynchronizedConfig class so it doesn't wait
1183 unnecessarily long after an update

1185 events (e.g. to highlight the pressed keys on the virtual keyboard
1186 of gigedit)
1187 - added support for triggering notes by instrument editors (see above)
1188 - be verbose on DLL load errors (on Linux)
1189 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1193 - experimental support for running LinuxSampler as a DSSI, LV2 and
1194 VST plugin

1200 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1201 - automatic stacktrace mechanism is now turned off by default and can
1202 be switched on by command line option "--stacktrace" (the automatic
1203 stacktrace mechanism seems to be broken on most systems at the moment)
1204 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1205 a pointer to the launched InstrumentEditor object
1206 - added optional 3rd party user data parameter for following
1207 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1208 InstrumentEditor::Launch(),

1210 - theoretical fix: made SynchronizedConfig follow C++0x memory
1211 model more strictly
1212 - fixes for using large audio device buffers
1213 - Windows: add the installation directory to the DLL search path
1214 when loading an editor plugin (solves problems with VST and

1219 - removed the nonsense audio channel constraint (which was hard coded to
1220 max. 100 audio channels) for most audio drivers
1221 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1222 opposed to the LSCP specs
1223 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1224 reflected the wrong value
1225 - fixed a memory management bug in ASIO driver
1226 - Makefile fix: JACK_CFLAGS wasn't used
1227 - JACK: use jack_client_open instead of the deprecated

1234 win64)
1235 - VST: added support for sample rate and buffer size changes
1236 - VST: close editor (Fantasia) when the VST is removed
1237 - VST: avoid opening Fantasia more than once for each VST instance

1239 energyXT)
1240 - VST: changed number of output channels from one stereo to 16
1241 stereo
1242 - added channel routing, fxsends and midi maps to the settings
1243 stored in the plugin state
1244 - performance optimization of AudioChannel::MixTo() and
1245 AudioChannel::CopyTo() methods using GCC vector exensions
1246 (if available)

1254 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1255 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1256 CoreMidi or AU
1257 - fixed mingw-w64 compilation error in MME driver
1258 - made program change handling in MIDI thread real-time safe by
1259 moving the logic to a non-RT thread

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

1737 (fixes undefined behavior if stolen voices belonged to a key group -
1738 this case was followed by a "killed voice survived" error message)
1739 - fixed minor issue with null/silence samples
1740 (those stole voices even though they don't need a voice at all which
1741 resulted in "voice stealing didn't work out" messages)
1742 - don't reset volume, pan, pitch and MIDI controller values on
1743 instrument or audio output device change

1751 - added command line parameters --lscp-addr and --lscp-port to override
1752 default IP address and port of LSCP server
