File size: 100123 byte(s)
* Fixed compilation error with Bison >= 3.6.0.

* Bumped version (2.1.1.svn58).

1 Version SVN trunk (?)
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++14 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++14 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++14).
10 - RTMath: Implemented floating point comparison methods
11 fEqual32(float,float) and fEqual64(double,double) which take the
12 expected floating point tolerances into account.
13 - Added public API C++ class "LFO", which is a cluster class encapsulating
14 all the sampler's LFO implementations to be used by 3rd party applications
15 (e.g. by Gigedit).
16 - Added int math square LFO implementation.
17 - Added int math saw LFO implementation.
18 - Added numeric complex nr sine LFO implementation.
19 - Marked class LFOTriangleDiHarmonic as deprecated
20 (will be removed in future).
21 - Added LFOAll.h which includes all LFO implementation's header files.
22 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25 SquareLFO -> LFOSquarePulse and separated the latter to its own header
26 file).
27 - Renamed type LFOSigned -> LFOTriangleSigned.
28 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29 - 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 - Added configure checks whether C++ compiler supports so called
55 'designated initializers'.
56 - Added global backtraceAsString() function for debugging purposes
57 (POSIX systems only, no Windows implementation yet).
58 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59 nameOfCaller() and setNameOfCaller().
60 - configure: Always check for availability of pthread_testcancel() and use
61 it if so (previously it was only used if explicitly enabled by configure
62 option).
63 - Thread class: raise compiler warning if pthread_testcancel() is not
64 available, because it can lead to deadlocks.
65 - Mutex class: Implemented optional bug detection and deadlock debugging
66 features.
67 - Ref<> class is now thread safe (as lock-free and wait-free
68 implementation).
69 - Fixed compilation error with Bison >= 3.6.0.
71 * Real-time instrument scripts:
72 - Added method ScriptVM::setExitResultEnabled() which allows to
73 explicitly enable the built-in exit() function to optionally accept
74 one function argument; the value of the passed exit() function
75 argument will then become available by calling
76 VMExecContext::exitResult() after script execution.
77 - 64 bit support for NKSP integer scripts variables (declare $foo).
78 - Variable names, function names and preprocessor condition names must start
79 with a regular character (a-z or A-Z); starting them with a digit or
80 underscore is not allowed.
81 - NKSP parser fix: equal comparison operator "=" and not equal comparison
82 operator "#" must only accept integer operands.
83 - NKSP language: Implemented support for standard units like Hertz, seconds,
84 Bel including support for metric unit prefixes; so one can now e.g.
85 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
86 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
87 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
88 - NKSP language: Introduced "final" operator "!" which is specifically
89 intended for synthesis parameter values to denote that the synthesis
90 parameter value is intended to be the "final" value for that synthesis
91 parameter that should explicitly be used by the engine and thus causing
92 the sampler engine to ignore all other modulation sources for the same
93 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
94 variable or formula with this new "!" operator the expression is marked as
95 being "final".
96 - NKSP script editor API: Added support for detecting standard unit tokens
97 and their potential metric prefix token.
98 - NKSP language: Added support for NKSP real number literals and
99 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
100 - NKSP language: Added support for NKSP real number (floating point) script
101 variables (declare ~foo).
102 - NKSP language: Added support for NKSP real number (floating point) array
103 script variables (declare ?foo[]).
104 - Built-in script function "message()" accepts now real number argument as
105 well.
106 - Added built-in script function "real_to_int()" and its short hand form
107 "int()" for casting from real number to integer in NKSP scripts.
108 - Added built-in script function "int_to_real()" and its short hand form
109 "real()" for casting from integer to real number in NKSP scripts.
110 - Allow built-in exit() function to potentially accept real number type
111 argument as well.
112 - Built-in script functions may have a different return type depending on
113 the arguments passed to the function.
114 - Built-in script function "abs()" optionally accepts and returns real
115 number.
116 - Built-in script functions "min()" and "max()" optionally accept real
117 number arguments and return real number as result in that case.
118 - NKSP VM API: Allow units and 'final'ness to be returned as result from
119 built-in functions (added methods VMFunction::returnUnitType() and
120 VMFunction::returnsFinal() for that purpose which must be implemented by
121 built-in function implementations).
122 - NKSP language: Allow metric unit prefixes of numeric scalar and array
123 variables to be changed freely at runtime (unlike unit types like Hz etc.
124 which are still sticky, parse-time features of variables which cannot be
125 changed at runtime for the intentional sake of determinism).
126 - NKSP language: 'final' values are prohibited for array variables for now
127 (attempt causes a parsers error).
128 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
129 conditions of runtime control structures like if(), while(), select()
130 (attempt causes a parser error).
131 - NKSP VM API: Allow built-in functions to perform their own, individual
132 parse time checks of arguments going to be passed to the function at
133 runtime (added method VMFunction::checkArgs() for that purpose).
134 - NKSP language: raise parser warning if only one operand of binary
135 operators (like logical 'or' comparison) contain a 'final' value (because
136 it would always yield in a 'final' result in such cases).
137 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
138 different metric unit prefixes, which will behave as expected (e.g.
139 result of expression '1000us < 2ms' is true).
140 - NKSP language: Allow adding values with different metric unit prefixes
141 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
142 - NKSP language: Allow subtracting values with different metric unit
143 prefixes (e.g. result of expression '1ms - 20us' is '980us').
144 - NKSP language: Allow multiplying with any metric unit prefixes
145 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
146 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
147 we don't have any considerable practical use for a term like '4s^2'
148 (hence any attempt multiplying two unit types still causes parser error).
149 - NKSP language: Allow dividing by any metric unit prefixes and allow
150 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
151 yields in unit free result '8'). So this is now a way to cast units away
152 e.g. for passing the result to other expressions, certain function calls
153 or variables which are not accepting any units (or that specific unit).
154 - NKSP language: integer arrays and real number arrays can now be converted
155 to strings (e.g. for dumping their content with message() calls for
156 script debugging purposes).
157 - NKSP language: expressions and variables with units are now correctly
158 casted to strings (e.g. with message() calls).
159 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
160 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
161 floating point tolerances into account.
162 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
163 VMScalarNumberExpr::evalCastReal().
164 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
165 'VMIntArrayExpr' and 'VMRealArrayExpr'.
166 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
167 unitFactor() (runtime) methods.
168 - Built-in function "exit()" supports now returning units and 'final'ness
169 for test cases.
170 - The following built-in functions support now units as well: "abs()",
171 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
172 "real_to_int()", "int()", "int_to_real()" and "real()".
173 - Built-in functions "array_equal()", "search()" and "sort()" support now
174 real number arrays (correctly) as well.
175 - Added individual parse time checks of arguments to be passed to built-in
176 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
177 "array_equal()" and "search()" specific for their individual purposes.
178 - NKSP VM refactoring: Renamed all methods, functions and classes matching
179 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
180 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
181 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
182 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
183 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
184 isScalarNumber() -> isNumber()).
185 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
186 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
187 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
188 as convenient methods for automatically converting values to expected
189 metric value basis.
190 - Built-in function "wait()" accepts now both integers and real numbers as
191 argument.
192 - NKSP VM API cleanup: Get rid of legacy method
193 VMFunction::argType(vmint iArg) which was already superseded by its new
194 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
195 - NKSP parser: if wrong argument type was passed to a built-in function and
196 that built-in function accepts more than one data type for the argument,
197 then show all supported data types as parser error message.
198 - Built-in function "play_note()" accepts now real numbers and seconds as
199 unit type as well for its 3rd and 4th function arguments.
200 - The following built-in functions accept now real numbers as well for their
201 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
202 "change_attack()", "change_decay()", "change_release()",
203 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
204 "change_cutoff_sustain()", "change_cutoff_release()",
205 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
206 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
207 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
208 - Fixed built-in function "change_play_pos()" not having accepted metric
209 prefixes at all.
210 - Fixed the following built-in functions having misinterpreted values given
211 with unit type (for their 2nd argument) as if they were relative values
212 (that is as if they were passed without a unit type): "change_attack()",
213 "change_decay()", "change_release()", "change_cutoff_attack()",
214 "change_cutoff_decay()", "change_cutoff_release()".
215 - Fixed the following built-in functions having applied completely wrong
216 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
217 respective EGs being their modulation sink assume uint data type with
218 value range 0..1000 instead of 0.0..1.0.
219 - Added individual parse-time checks of function arguments for the following
220 built-in functions: "play_note()", "note_off()", "set_event_mark()",
221 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
222 "change_decay()", "change_release()", "change_cutoff_attack()",
223 "change_cutoff_decay()", "change_cutoff_release()",
224 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
225 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
226 "change_pan_time()".
227 - Don't abort function call if unit type was used and at the same time
228 'final' operator was omitted for the primary value argument of the
229 following built-in functions: "change_cutoff()", "change_attack()",
230 "change_decay()", "change_release()", "change_cutoff_attack()",
231 "change_cutoff_decay()", "change_cutoff_release()",
232 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
233 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
234 "change_pan_time()", instead imply 'final'ness at runtime and raise an
235 appropriate parser warning at parse time.
236 - Added built-in real number functions "round()", "ceil()", "floor()",
237 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
238 "cos()", "tan()", "asin()", "acos()", "atan()".
239 - Added built-in script real number constant "~NI_MATH_PI".
240 - Added built-in script real number constant "~NI_MATH_E".
241 - NKSP language: Allow unary '+' operator.
242 - Added built-in script functions "msb()" and "lsb()".
243 - NKSP language: Added support for RPN event handler
244 ("on rpn ... end on" in instrument scripts).
245 - NKSP language: Added support for NRPN event handler
246 ("on nrpn ... end on" in instrument scripts).
247 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
248 may be read from the new RPN/NRPN script handlers to get the (N)RPN
249 parameter that had been changed and its new value.
250 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
251 which are identifying the new (N)RPN handlers as such at script runtime.
252 - Implemented built-in script function "set_rpn()".
253 - Implemented built-in script function "set_nrpn()".
254 - Fix: built-in functions returning an array type were broken and caused a
255 crash when the built-in function's (supposed to be array) result value was
256 used by the script VM.
257 - Removed upper value constraint for 2nd argument of built-in functions
258 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
259 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
260 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
261 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
262 the LFO frequency / resonance / cutoff frequency.
263 - Reduced code involved for parsing NKSP variable declarations by using 2
264 generalized grammar rules with optional components (i.e. optional value
265 assignment and optional variable qualifiers) instead of previous linear
266 combinations of grammar rules, which also fixes some edge case.
267 - NKSP language parser: track code block locations also by a) raw byte
268 position in NKSP source code string and b) length of that code block in
269 bytes (along to the already existing code block tracking by line/column);
270 and added appropriate new members to public C++ API classes like
271 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
272 - NKSP language: Added support for 'patch' variable qualifier (capture their
273 locations and allow replacement of their assignment expression via VM C++
274 API).
275 - Fixed incorrect EG times if standard measuring unit was passed to built-in
276 functions "change_attack()", "change_decay()" or "change_release()".
277 - Fixed intermediate function result values never having reflected any
278 standard measuring unit type.
279 - Fixed re-entrant issue with function calls which caused wrong result
280 values if the same function was called multiple times in a term
281 (specifically if metric prefixes were used).
283 * test cases:
284 - Fixed compiler errors in test cases.
285 - Updated README for how to compile & run test cases.
286 - Updated test case
287 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
288 expected behaviour of the Mutex class implementation (recursive
289 mutex type).
290 - Added test cases for NKSP core language aspects and core built-in
291 functions.
292 - Fixed thread tests segfaulting on Linux.
293 - NKSP: Added real number test cases for built-in functions exit(),
294 int_to_real(), real(), real_to_int() and int(), as well as for the
295 plus, minus and negate language operators.
296 - Added massive amount of NKSP test cases for standard measuring units and
297 'final' operator usage cases.
298 - Added NKSP test cases for (floating point tolerance aware) real number
299 equalness / unequalness comparison.
300 - Added NKSP int array and real array tests for value assignment and
301 initialization of arrays.
302 - Added NKSP test cases for built-in functions "round()", "ceil()",
303 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
304 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
305 - Added NKSP test cases for unary '+' operator.
306 - Added NKSP test cases for core built-in variables.
307 - Added thorough NKSP test cases for variable declarations.
309 * GigaStudio/Gigasampler format engine:
310 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
311 behaviour for start_level_mid.
312 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
313 level (see discussion "GigaStudio LFO compatibility" on mailing list
314 from 2019-09-26 for details).
315 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
316 see discussion "GigaStudio LFO compatibility" on mailing list from
317 2019-09-26 for details).
318 - Format extension: Added support for different LFO wave forms (currently
319 either sine [default], triangle, saw or square).
320 - Format extension: Added support for LFO phase displacement (0��..360��).
321 - Format extension: Added support for flipping LFO polarity on LFO 3
322 (in the original gig format this was only available for LFO 1 and LFO 2).
323 - Format extension: Support for additional filter types:
324 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
325 bandreject 2-pole.
326 - Fixd potential crash with polynomial interpolator and max. pitch.
327 - If minimum cutoff is defined, remap cutoff controller CC values to really
328 span the entire possible cutoff range (and avoiding a dead controller
329 zone).
330 - Implemented support for loading instrument scripts with 'patch' variables
331 (by patching these script variables with potentially overridden ones by
332 gig Instrument).
334 * SFZ format engine:
335 - Fixed support for regions with loccN/hiccN conditions on more than one
336 MIDI controller.
338 * Benchmarks:
339 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
340 algorithm (since result of 2nd run was not accumulated).
341 - Added benchmark for saw wave (benchmarks/saw.cpp).
342 - Added benchmark for sine wave (benchmarks/sine.cpp).
343 - Added benchmark for square wave (benchmarks/square.cpp).
344 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
345 which are large enough on modern systems.
347 Version 2.1.1 (27 Jul 2019)
349 * Real-time instrument scripts:
350 - Fixed behavior of built-in NKSP functions change_sustain(),
351 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
352 and change_cutoff_release().
354 * general changes:
355 - Only play release trigger samples on sustain pedal up if this behaviour
356 was explicitly requested by the instrument (otherwise only on note-off).
357 - Fixed compiler warnings.
358 - Fixed compilation error when cross-compiling to Mac.
359 - FX Sends: Provide more useful error messages on routing problems
360 (see bug #169).
361 - LSCP doc: Be more clear describing the two distinct approaches
362 of using external vs. internal effects (see bug #169).
363 - "optional" class: Fixed comparison operators.
365 * Gigasampler/GigaStudio format engine:
366 - Format extension: If requested by instrument then don't play release
367 trigger sample on note-off events.
369 * SFZ format engine:
370 - Fixed memory leak when releasing samples
371 (fixes bug #307, patch by Jacek Roszkowski)
372 - Fixed potential crash when a sample is shared by more than one region
373 (fixes bug #308, patch by Jacek Roszkowski).
374 - Opcode 'sample': Added support for built-in sample '*silence'
375 (fixes bug #310, patch by Jacek Roszkowski).
377 Version 2.1.0 (25 Nov 2017)
379 * SFZ format engine:
380 - added support for <global>, <master> and #define (patch by Alby M)
381 - Removed code duplication in SFZ file loading code.
382 - Added support for sfz extension opcode 'script' which may be used to
383 load real-time instrument script file (NKSP script language).
384 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
385 - Fixed unintended volume fade-in of voices under certain conditions.
386 - sfz parser: allow missing space between header and opcode
388 * Gigasampler/GigaStudio format engine:
389 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
390 cutoff settings.
391 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
392 all if an up-pitch of more than 40 semi tones was requested (I don't
393 think there is any stock gig sound that requires this behavior to
394 resemble its original sound).
395 - Added support for controlling whether the individual EGADSR stages may
396 be aborted (as LinuxSampler extension to the original GigaStudio 4
397 format).
399 * general changes:
400 - fixed printf type errors (mostly in debug messages)
401 - use unique_ptr instead of auto_ptr when building with C++11
402 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
403 allowing to sort data efficiently in real-time safe manner.
404 - RTList class: added methods for moving/inserting elements to arbitrary
405 position within a list.
406 - RTList class: added method fromPtr() for creating an Iterator object from
407 a raw element pointer.
408 - Attempt to partly fix resetting engine channels vs. resetting engine, an
409 overall cleanup of the Reset*(), ConnectAudioDevice(),
410 DisconnectAudioDevice() API methods would still be desirable though,
411 because the current situation is still inconsistent and error prone.
412 - Active voices are now internally grouped to "Note" objects, instead of
413 being directly assigned to a keyboard key. This allows more fine graded
414 processing of voices, which is i.e. required for certain instrument
415 script features.
416 - Fix: Release trigger voices were not spawned on sustain pedal up
417 (CC #64) events.
418 - Fix: Release trigger voices can now also distinguish correctly between
419 note-off and sustain pedal up events.
420 - All engines: Increased ramp speed of volume smoother and pan smoother
421 (while slow rate of crossfade smoother is preserved) to allow quick
422 volume and pan changes by instrument scripts for instance.
423 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
424 properly and thus were ignored for certain uses.
425 - Added new C++ API method
426 VirtualMidiDevice::SendChannelPressureToSampler().
427 - windows, 32-bit: fixed potential crashes by making sure the stack in
428 sub threads is 16-byte aligned
429 - fixed numerous compiler warnings
430 - Fixed invalid (note-on) event ID being assigned to new Note objects.
431 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
432 fixes potential undefined behavior.
433 - Fixed Note object leak when triggering notes on keys which did not
434 have a valid sample mapped (fixes bug #252).
435 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
436 - linuxsampler binary fix: option --create-instruments-db ignored
437 subsequent optional argument due to glibc's implementation oddity
438 which expects a "=" sign, but no space between them.
440 * packaging changes:
441 - removed unnecessary dependency to libuuid
442 (originated by libgig's usage of it)
443 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
444 auto detect whether it (sh/c)ould output its messages in color.
445 - Debian: Fixed packaging error about invalid "Source-Version"
446 substitution variable.
447 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".

449 linuxsampler with instruments DB support.
451 * Real-time instrument scripts:
452 - Implemented scheduler for delayed MIDI events and for suspended scripts.
453 - Built-in script function "wait()": implemented support for function's
454 "duration-us" argument, thus scripts using this function are now
455 correctly resumed after the requested amount of microseconds.
456 - Built-in script function "play_note()": implemented support for
457 function's "duration-us" argument, thus notes triggered with this
458 argument are now correctly released after the requested amount of
459 microseconds.
460 - Fix: script events were not cleared when engine channel was reset,
461 potentially causing undefined behavior.
462 - Fixed crash which happened when trying to reference an undeclared
463 variable.
464 - Built-in script function "play_note()": Added support for passing
465 special value -1 for "duration-us" argument, which will cause the
466 triggered note to be released once the original note was released.
467 - Instrument script classes now exported with the liblinuxsampler C++ API.
468 - Added new API method ScriptVM::syntaxHighlighting() which provides
469 a convenient syntax highlighting backend for external instrument
470 script editor applications.
471 - Added new C++ API class "ScriptVMFactory".
472 - Extended parser issues to provide not only first line and first
473 column, but also last line and last column of issue (thus marking
474 the precise span of the issue within the source code).
475 - Reload script automatically after being modified by an instrument
476 editor.
477 - NKSP language grammar correction: allow empty event handler bodies
478 like "on note end on".

484 - Implemented built-in script function "event_status()".
485 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
486 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
487 "event_status()" function.
488 - NKSP language: Added support for bitwise operators ".or.", ".and."
489 and ".not.".
490 - NKSP language scanner: Fixed IDs matching to require at least one
491 character (i.e. when matching function names or variable names).
492 - NKSP language scanner: disabled unusued rules.
493 - Fixed behavior of play_note() and note_off() functions which must
494 be distinguished engine internally from "real" MIDI note on/off
495 events in order to avoid misbehaviors like hanging notes.
496 - Implemented built-in script variable "$KSP_TIMER".
497 - Implemented built-in script variable "$NKSP_REAL_TIMER".
498 - Implemented built-in script variable "$NKSP_PERF_TIMER".

502 - NKSP language fix: division expressions were evaluated too often.
503 - NKSP language fix: string concatenation operator was right
504 associative instead of left (to right).
505 - NKSP language correction: allow empty statements in entire language
506 (i.e. "if end if").
507 - Implemented built-in script function "stop_wait()".

518 - Implemented built-in script function "change_attack()".
519 - Implemented built-in script function "change_decay()".
520 - Implemented built-in script function "change_release()".
521 - Fixed all change_*() built-in script functions to apply their
522 synthesis parameter changes immediately in case the respective note
523 was triggered at the same time, instead of scheduling the parameter
524 change, especially because it would cause some parameter types's
525 changes either to be ramped (i.e. change_vol()) or other types even
526 to have not effect at all (i.e. change_attack()).
527 - Implemented built-in script function "sh_left()".
528 - Implemented built-in script function "sh_right()".
529 - Implemented built-in script function "min()".
530 - Implemented built-in script function "max()".
531 - NKSP Fix: "init" event handler was not always executed when a script
532 was loaded.
533 - NKSP built-in wait() script function: abort script execution if
534 a negative or zero wait time was passed as argument (since this is
535 a common indication of a bug either of the script or even of the
536 engine, which could lead to RT instability or even worse).
537 - ScriptVM: Implemented automatic suspension of RT safety
538 threatening scripts.
539 - Provide more user friendly error messages on syntax errors.
540 - Fixed NKSP parser warning "Not a statement" when assigning an
541 initializer list to an array variable.

548 - Implemented built-in script function "change_vol_time()".
549 - Implemented built-in script function "change_tune_time()".
550 - Implemented built-in script function "fade_in()".
551 - Implemented built-in script function "fade_out()".
552 - Fixed acceptance of wrong data type of parameters passed to built-in
553 script functions "change_vol()", "change_tune()", "change_pan()",
554 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
555 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
556 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
557 - Added built-in script function "get_event_par()" and implemented some
558 of its possible parameter selections.
559 - Added built-in script function "set_event_par()" and implemented some
560 of its possible parameter selections.
561 - Fixed a bunch of scheduler time related bugs.
562 - Fixed polyphonic variables not being reset to zero after usage.
563 - Built-in "ignore_event()" function: argument is now optional, like with
564 built-in function "ignore_controller()".
565 - Implemented built-in script function "change_velo()".
566 - Implemented built-in script function "change_note()".
567 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
568 intuitive behavior if used in combination with "change_vol_time()" or
569 "change_tune_time()" respectively: now tuning/volume changes are only
570 assigned (without delay) immediately to a new note if the respective
571 timing function has not been called before, otherwise the volume/tuning
572 changes are automatically faded (before, only the event's time stamp was
573 relevant).
574 - Implemented built-in script function "array_equal()".
575 - Implemented built-in script function "search()".
576 - Implemented built-in script function "sort()".
577 - NKSP Fix: Never suspend "init" event handlers.
578 - Implemented built-in script function "same_region()" (currently only
579 available for gig format engine).
580 - Added built-in script constant "$NKSP_LINEAR".
581 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
582 - Implemented built-in script function "change_vol_curve()".
583 - Implemented built-in script function "change_tune_curve()".
584 - built-in "play_note()" function now supports a sample playback start
585 offset with argument 3, where special value -1 means to use the regular
586 sample offset as defined by the instrument file.
587 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
588 - Built-in variable $EVENT_NOTE is now a read-only variable.
589 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
590 - built-in "play_note()" function now accepts -2 for its fourth argument
591 (note duration) which means the life time of the note shall be sticked
592 to the requested note number of argument 1.
593 - Fix: built-in "play_note()" function now returns 0 as result value if
594 -1 was passed for its fourth argument (note duration) and the respective
595 parent note is already gone.
596 - Implemented built-in script function "change_play_pos()".
597 - NKSP language: Added support for user declared const array variables.
598 - NKSP language: Raise parser warning if array variable is accessed with
599 an index that exceeds the array's size.
600 - NKSP language fix: Unknown characters were not handled correctly.
601 - NKSP language: Added support for "synchronized .. end synchronized"
602 code blocks.
603 - Implemented built-in script function "abort()" which allows to abort
604 another script handler by passing its callback ID.
605 - Fixed potential memory access bug and potential undefined behavior of
606 "init" event handlers.
607 - Print a time stamp along to each call of built-in function "message()".
608 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
609 to retrieve all code blocks filtered out by the preprocessor.
610 - Added built-in script function "fork()".
611 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
612 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

616 - Added built-in constant $CALLBACK_STATUS_QUEUE.
617 - Added built-in constant $CALLBACK_STATUS_RUNNING.
618 - Removed max. value limitation of built-in functions "change_attack()",
619 "change_decay()" and "change_release()" to i.e. allow passing 2000000
620 for doubling the respective time.
621 - NKSP script editor syntax highlighting API: Fixed app termination due
622 to a lexer start condition stack underrun.
623 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
624 USE_CODE_IF_NOT() preprocessor statements.
625 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
626 can be set to disable all subsequent built-in "message()" function calls
627 on preprocessor level.
628 - Implemented built-in script function "change_sustain()".
629 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

642 undefined behavior.
643 - Cleanup of instruments DB file creation and opening code.

645 is now optional, if it is missing, then a default location is used.
646 - Added support for scanning SFZ (.sfz) files.
647 - Added support for scanning Sound Font (.sf2) files.
648 - Fixed undefined DB transaction behavior.

658 - removed empty directories left from the cvs to svn migration
659 - fixed compilation with gcc 4.6.1
660 - another "make dist" fix, for the LV2 plugin
661 - made --enable-pthread-testcancel default on Mac OS X
662 - minor Makefile fix for building lscpparser when build and source
663 directories are separate
664 - Mac OS X: made it possible to specify plugin installation dir to
665 configure
666 - Mac OS X: Makefile fix for the install-strip target
667 - fixed compilation with gcc 4.7
668 - fixed configure script error with old autoconf versions
669 - lsatomic.h: use gcc provided atomic functions if building with
670 gcc 4.7 and C++11
671 - modernized configure script
672 - fixed linkage error when building with
673 LDFLAGS="-Wl,--no-undefined" (#190)
674 - fixed compilation with Clang 3.2
675 - removed usage of deprecated Automake variable INCLUDES

678 - build fix: libsndfile compiler flags were missing in some
679 makefiles
680 - fix for building with bison 3.0 (#202)
681 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
682 on the process's main thread
683 - fixed build error on newer MinGW
684 - support building with older jack versions
685 - support building with spaces in vst sdk path
686 - enabled automake 'subdir-objects' option and moved external
687 source references (vst, au, asio) from makefiles to cpp files,
688 in order to get rid of warnings from automake 1.14
690 * general changes:
691 - Refactoring: moved the independent code from
692 the Gigasampler format engine to base classes
693 - command line option '--profile' is currently disabled, since the
694 respective profiling code is currently broken
695 - Introduced support for optional environment variable
696 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
697 where the sampler shall look for instrument editor plugins
698 (patch by Luis Garrido, slightly modified).
699 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
700 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
701 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
702 note (in this implementation of the sampler its simply hard routed to
703 the 1st effect send of the sampler channel, no matter what the actual
704 effect type is)
705 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
706 note (in this implementation of the sampler its simply hard routed to
707 the 2nd effect send of the sampler channel, no matter what the actual
708 effect type is)
709 - implemented support for internal LADSPA effects
710 - raised limit of program change queue from 100 to 512
711 (as suggested by Alex Stone)
712 - implemented sine LFO, pulse LFO and saw LFO
713 - experimental support for per voice equalization
714 - added command line option --exec-after-init
715 - Introduced new C++ API method:
716 EngineChannel::InstrumentFileName(int index)
717 allowing to retrieve the whole list of files used for the loaded
718 instrument on an engine channel (a.k.a. part). Some GigaStudio
719 instruments for example are splitted over several files like
720 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
721 - Added new C++ API method Sampler::GetGlobalMaxVoices().
722 - Added new C++ API method Sampler::GetGlobalMaxStreams().
723 - Added new C++ API method Sampler::SetGlobalMaxVoices().
724 - Added new C++ API method Sampler::SetGlobalMaxStreams().
725 - Various "const" and "restrict" optimizations.
726 - all engines: add pan CC value to instrument pan parameter before
727 applying panning, instead of using two separate pan functions in
728 series (#182)
729 - added a lock guard class for exception safe mutex handling and
730 used it everywhere appropriate
731 - Immediately apply scale tuning changes to active voices.
732 - Exposed scale tuning to C++ API (along to the already existing standard
733 SysEx way).
734 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
735 and broken for ppc64. (Seq_cst loads and stores are actually not
736 used in LS, so the bug wasn't noticable.)
737 - lsatomic.h: added ARMv7 support
738 - Added support for multiple MIDI input ports per sampler channel (and
739 added various new C++ methods for this new feature / design change, old
740 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
741 as deprecated but are still there and should provide full behavior
742 backward compatibility).
743 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
744 unsafe and caused compilation error with clang 2.x).
745 - Bugfix: only process the latest MIDI program change event.
746 - Introducing the LSCP shell, which provides convenient control of the
747 sampler from the command line by providing LSCP aware features.
748 - VirtualMidiDevice: Added support for program change.
749 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
750 - VirtualMidiDevice: Added support for pitch bend.
751 - Aftertouch: extended API to explicitly handle channel pressure and
752 polyphonic key pressure events (so far polyphonic pressure was not
753 supported at all, and channel pressure was rerouted as CC128 but not
754 used so far).
755 - Added initial support for real-time instrument scripts. The script VM
756 code is shared by all sampler engine implemementations, however only the
757 gig file format currently provides support for storing instrument scripts
758 (as LinuxSampler extension to the original GigaStudio 4 format).
760 * Gigasampler format engine:
761 - implemented the "round robin keyboard" dimension
762 - fixed round robin and random dimensions for cases when number of
763 dimension zones is not a power of two
764 - made round robin use a counter for each region instead of each
765 key
766 - bugfix: pitch LFO controller "internal+aftertouch" was broken
767 - bugfix: filter keyboard tracking was broken
768 - filter performance fix (an unnecessary copy was made of the
769 filter parameters in each sub fragment)
770 - handle special case when pan parameter in gig file has max or
771 min value
772 - Exclusive Groups: don't ever stop voices of the same note,
773 doesn't sound naturally with a drumkit
774 - fixed EG1 modulation when attack or release is zero
775 - Fixed support for 'aftertouch' attenuation controller.
776 - Fixed crash that happened with velocity split sounds under certain
777 conditions (see also previous commit on libgig).
778 - fixed behaviour of filter LFO
780 * SFZ format engine:
781 - Initial implementation (not usable yet)
782 - added support for v2 multiple stage envelope generators
783 - added a fine-tuned v1 envelope generator instead of using the
784 one from the gig engine
785 - fixed memory leak and memory handling errors
786 - added support for trigger=first, trigger=legato and sw_previous
787 - allow non-numerical key values ("C#4" for example)
788 - "key" opcode now sets pitch_keycenter too
789 - fixed error when unloading instrument with same sample used by
790 multiple regions
791 - added some opcode aliases, like loopmode for loop_mode, to be
792 more compatible
793 - added support for trigger=release and rt_decay
794 - added support for off_mode=normal
795 - added support for random, seq_position, seq_length and volume
796 - added v1 LFO opcodes to parser (no support in engine yet)
797 - added support for amp_veltrack and amp_velcurve_N
798 - fine-tuned the default velocity curve
799 - added support for transpose
800 - fixed crash when using sw_down/up
801 - improved logic for sw_lokey/hikey/up/down/last
802 - added more v1 aliases to parser
803 - reduced memory usage for sfz data
804 - RT-safeness: avoid malloc in audio thread
805 - fixed a bug that could cause voice stealing to fail
806 - optimized sample lookup
807 - improved support for exclusive groups (group, off_by and
808 off_mode)
809 - added support for controller triggered regions (on_locc/on_hicc)
810 - added support for loop_mode=one_shot
811 - fixed playback of 16 bit wav files on big endian CPUs
812 - added support for Ogg Vorbis sample files
813 - use loop markers from sample file if loop_start and loop_end are
814 not set in sfz file
815 - implemeted filters. Filter types: lowpass, bandpass, bandreject
816 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
817 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
818 cutoff_cc, cutoff_chanaft.
819 - bugfix: zero ampeg_sustain didn't work
820 - added support for velocity effect on amplifier envelope time
821 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
822 ampeg_vel2release)
823 - added support for EG hold (ampeg_hold)

1008 the driver will automatically connect to other CoreMIDI clients' ports
1009 (e.g. external MIDI devices being attached to the Mac)
1010 - added support for MIDI note on velocity filter
1011 - CoreMIDI: fixed memory deallocation error
1012 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1186 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1187 practically irrelevant, however it caused problems with the new LSCP
1188 shell's auto completion feature).
1189 - Fixed MIDI program change messages being ignored if quickly executed
1190 after each other (fixes #231).

1225 of gigedit)
1226 - added support for triggering notes by instrument editors (see above)
1227 - be verbose on DLL load errors (on Linux)
1228 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1230 implementation, which is usually faster)
1231 - fixes for audio drivers with varying buffer sizes
1232 - experimental support for running LinuxSampler as a DSSI, LV2 and
1233 VST plugin

1238 - maximum voices and disk streams can now be altered at runtime
1239 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1240 - automatic stacktrace mechanism is now turned off by default and can
1241 be switched on by command line option "--stacktrace" (the automatic
1242 stacktrace mechanism seems to be broken on most systems at the moment)
1243 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1244 a pointer to the launched InstrumentEditor object
1245 - added optional 3rd party user data parameter for following
1246 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1247 InstrumentEditor::Launch(),

1249 - theoretical fix: made SynchronizedConfig follow C++0x memory
1250 model more strictly
1251 - fixes for using large audio device buffers
1252 - Windows: add the installation directory to the DLL search path

1259 max. 100 audio channels) for most audio drivers
1260 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1261 opposed to the LSCP specs
1262 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1263 reflected the wrong value
1264 - fixed a memory management bug in ASIO driver
1265 - Makefile fix: JACK_CFLAGS wasn't used
1266 - JACK: use jack_client_open instead of the deprecated

1280 stereo
1281 - added channel routing, fxsends and midi maps to the settings
1282 stored in the plugin state
1283 - performance optimization of AudioChannel::MixTo() and
1284 AudioChannel::CopyTo() methods using GCC vector exensions

1294 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1295 CoreMidi or AU
1296 - fixed mingw-w64 compilation error in MME driver
1297 - made program change handling in MIDI thread real-time safe by
1298 moving the logic to a non-RT thread

1309 instrument database compilable
1310 - added instrument database support on Windows
1311 works with both standalone mode and VST plugin.
1312 the instruments DB file is located in
1313 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1314 databases for each windows user
1315 if no DB is present it automatically creates the .linuxsampler subdir
1316 and then creates an empty DB
1317 - fixed recursive import, which was broken on Windows
1319 * Gigasampler format engine:
1320 - fixed a memory leak that could happen when a channel was deleted
1321 while notes were playing
1322 - made it possible to load an instrument even if the audio thread
1323 isn't running
1324 - added partial support for the "Controller Triggered" MIDI rule,
1325 enough for piano gigs with pedal noise samples
1326 - minor fix: only mark FX sends as being modified if really the
1327 respective FX send MIDI controller was used
1328 - added support for GM global device volume SysEx message
1329 (can be selected at compile time to either apply globally to the
1330 whole sampler [default] or only to the sampler channels that are
1331 connected to the respective MIDI input port the SysEx message arrived
1332 on)
1333 - bugfix: notes triggered at position 0 in the audio buffer were
1334 sometimes wrongly killed in the same buffer, causing no sound to
1335 be played
1336 - added support for chromatic / drumkit mode Roland GS Sysex message
1337 which is usally used to switch a part between chromatic sounds and
1338 drumkit sounds (as opposed to their common default setting of MIDI
1339 part 10 being a drumkit part and all other ones chromatic parts), in
1340 LS however one can switch between the first 16 MIDI instrument maps
1341 defined for the sampler
1342 - made it possible to create multiple sample channels even if the
1343 audio thread isn't running
1344 - fixed crash when removing channel with active voices (#116)
1345 - bugfix: on sample reference changes (instrument editor), only
1346 un-cache the respective sample if it's really not used by any
1347 sampler engine anymore
1348 - re-cache samples in case they were changed by an instrument editor,
1349 e.g. when a sample was added while playing (#82)
1350 - fixed hanging notes which occured when note-off event had the exact
1351 same time stamp as the voice's note-on event and occured both in the
1352 same audio fragment cycle (fixes bug #112)
1353 - added support for the "fine tune" and "pitch bend range"
1354 instrument-level gig parameters
1355 - fixed minor artifacts in pitch bend handling
1356 - added support for GS Reset SysEx message
1357 - allow gig files to use unlimited downward pitch shifting
1358 - added a limit check for upward pitch shifting
1359 - bugfix: sometimes, when playing a note twice fast, the second
1360 note was silent
1361 - fixed crash happening when a pitch bend event arrived at the
1362 same time a new instrument was loading
1364 * LSCP server:
1365 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1366 react on MIDI data arriving on certain sampler channels (so far only
1367 Note-On and Note-Off events are sent via this LSCP event)
1368 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1369 react on MIDI data arriving on certain MIDI input devices (so far only
1370 Note-On and Note-Off events are sent via this LSCP event)
1371 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1373 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1374 frontends to send MIDI messages to specific sampler channel
1375 - added two additional fields to GET FILE INSTRUMENT INFO command -
1377 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1378 was incorrect
1379 - Optimized the retrieval of the MIDI instrument mappings
1380 - added new LSCP command "SET VOICES" to globally alter the maximum
1381 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1382 be triggered respectively
1383 - added new LSCP command "SET STREAMS" to globally alter the maximum
1384 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1385 which will be triggered respectively
1386 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1387 a gigedit file dialog is opened)
1388 - close all connections when LSCPServer is deleted
1389 - hard close of all sockets on exit
1390 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1391 driver
1393 * Bug fixes:
1394 - fixed a crash which occurs when removing a sampler channel waiting
1395 to start instrument loading after another channel
1396 - fixed a crash which occurs when removing a sampler channel with
1397 instrument loading in progress (bug #113)
1398 - fixed termination caused by uncaught exception when adding MIDI
1399 instrument with PERSISTENT load mode
1400 - fixed possible iterator invalidations when resetting the sampler
1401 - fixed memory leaks when issuing the following LSCP commands:
1406 - fixed possible compilation error when sqlite is not present
1407 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1408 - fixed crash when changing the audio output device of a sampler
1409 channel with loaded instrument and start playing notes
1410 - fixed endless loop in Engine::SuspendAll() (bug #120)
1411 - fixed a low-level atomic load function that was broken on 64-bit
1412 PowerPC, which probably could cause crashes on that platform
1413 - fixed a memory management error which could cause a crash when a
1414 plugin was unloaded
1415 - bugfix: two private structs had the same name, which could cause
1416 problems if the linker chose the wrong constructor
1417 - fixed low-level ConditionServer usage bug that caused lockups on
1418 Windows
1421 Version 0.5.1 (6 December 2007)
1423 * packaging changes:
1424 - added autoconf checks for pthread library
1425 - added autoconf check for pthread bug found on certain NPTL-enabled
1426 glibc versions (see Gentoo bug report #194076)
1427 - added autoconf checks for MS Windows
1429 * general changes:
1430 - bugfix: the thread used by an editor plugin didn't die when the
1431 editor closed
1432 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1433 out all the space. operator--() did not apply size_mask after
1434 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1435 order to avoid problems with the _NonVolatileReader functions.
1436 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1437 GetWriteSpace(). Since this function is currently only used in
1438 the stream's qsort() compare function, it didn't trigger any
1439 bugs.
1440 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1441 24bit mode too. Faster method to read 24bit words on little
1442 endian machines (x86): replaced 3 byte reads + shifts with a 1
1443 unaligned 32bit read and shift
1444 - experimental support for MS Windows (MIDI input via MME, AUDIO
1445 output via ASIO)
1446 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1447 - support for monitoring the total number of active disk streams
1448 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1451 * AUDIO driver:
1452 - added Windows ASIO low latency audio driver
1454 * MIDI driver:
1455 - added MME Windows MIDI driver
1457 * LSCP server:
1458 - added support for Windows style path / filenames, however with
1459 forward slash path separators instead of backslash
1460 (i.e. "C:/foo/bar.gig")
1461 - allow naughty liblscp to send non-string device parameters within
1462 apostrophes as well
1463 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1464 "LIST FILE INSTRUMENTS <file>" and
1465 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1466 about an arbitrary instrument file on the system where the sampler is
1467 running on
1469 Version 0.5.0 (15 October 2007)
1471 * packaging changes:
1472 - config.h is not going to be installed along with liblinuxsampler's
1473 API header files anymore
1474 - only the API relevant header (and source) files will be exported to
1475 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1476 - added completely new XCode project files for Mac OSX which is now
1477 capable to execute our autoconf environment, thus no need anymore
1478 to maintain the compile time configuration file (osx/version.h) for
1479 OSX manually (patch by Toshi Nagata)
1480 - fixed buggy boolean --enable-foo / --disable-foo configure script
1481 parameters
1482 - global.h now only covers global definitions that are needed for the
1483 C++ API header files, all implementation internal global definitions
1484 are now in global_private.h
1485 - atomic.h is not exposed to the C++ API anymore
1486 - no need to include config.h anymore for using LS's API header files
1487 - fixed warnings in API doc generation
1489 * general changes:
1490 - replaced the old, confusing MIDI program change mechanism by a
1491 flexible MIDI instrument mapper which allows to map arbitrary
1492 (MIDI bank, MIDI program) pairs with arbitrary
1493 (engine type, instrument file, file index) triplets which will be
1494 loaded on the respective channel when such MIDI program change
1495 messages arrive, beside that, each entry allows to define a life-time
1496 strategy for the instrument, so the user can define whether the
1497 instrument should i.e. be permanently loaded (to be able to switch
1498 quickly among sounds) or i.e. loaded just on demand when the
1499 respective program change arrives (to safe RAM space), as well as a
1500 global volume factor for each entry, so the user can adjust the volume
1501 dynamic of his mapped instrument collection without having to modify
1502 the instrument files, also one can manage arbitrary amount of such
1503 MIDI instrument maps and assign each sampler channel individually
1504 a certain map, so that i.e. separation of normal instruments and
1505 drumkits is possible
1506 - new notification events for tracking changes to audio/MIDI devices,
1507 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1508 - sampler was limited to load max. 200 instruments in the background
1509 due to a constant size RingBuffer FIFO which is now replaced by a
1510 dynamic (unlimited) size std::list FIFO
1511 - added FX sends, these allow to route audio signals to arbitrary audio
1512 output channels for being processed by external effect processors
1513 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1514 controllers
1515 - global (sampler wide) volume can now be controlled at runtime
1516 - Implemented new, improved notification system
1517 - fixed compilation errors regarding OSX
1518 (patch by Toshi Nagata)
1519 - implemented instruments database
1520 - added support for escape sequences to the instruments database
1521 - added highly experimental support for on-the-fly instrument editing
1522 within the sampler's process (by using instrument editor plugins),
1523 you'll notice the new "Registered instrument editors:" message on
1524 startup, added a new LSCP command:
1525 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1526 to spawn a matching instrument editor for the instrument on the
1527 given sampler channel, the plugin path can be overridden at compile
1528 time with ./configure --enable-plugin-dir=/some/dir
1529 - added experimental code for synchronizing instrument editors hosted
1530 in the sampler's process to safely edit instruments while playing
1531 without a crash (hopefully) by either suspending single regions
1532 wherever possible or if unavoidable whole engine(s)
1533 - fixed several issues in fundamental "Thread" class: set scheduling
1534 policy and priority on thread level, set a minimum stack size for
1535 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1536 threads simply inherited properties of starting thread instead of
1537 setting their own policy and priority
1538 - minor fix in our automatic stack trace mechanism on crashes, the
1539 main process did not wait for the stack trace process to finish
1540 its output
1541 - fixed some minor memory leaks
1542 - reenabled assembly features support, at the moment only for
1543 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1544 - minor assembly fix in x86 features detection (don't use the PIC
1545 register, to avoid relocations in the text segment at runtime)
1546 - POSIX callback functions of Thread.h are hidden
1548 * MIDI driver:
1549 - dispatch bank select (MSB and LSB) messages
1551 * audio driver:
1552 - the ALSA audio output driver parameters now reflect the correct
1553 parameter value ranges for the respective selected sound card
1554 (patch by Till Wimmer, a bit fixed and extended)
1556 * Gigasampler format engine:
1557 - if a filter is used and EG2 finishes before EG1, let the voice
1558 die when EG2 has finished (this fixes a problem with clicks and
1559 voice starvation for some gigs)
1560 - playback is no longer disabled during instrument loading
1561 - all notes playing on a channel that changes its instrument keep
1562 playing with the old instrument until they get a note off
1563 command
1564 - EG fix: a release value of zero could cause noises or crash
1565 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1566 - EG fine tuning: when attack is zero the EG starts at a level
1567 above max sustain level, which means that there is a decay phase
1568 even if sustain is 100%
1569 - more EG fixes: the level could sometimes go below zero and cause
1570 noises or crashes
1571 - minor fix of EGDecay (patch by Toshi Nagata)
1572 - fixed compiler error when --enable-override-filter-type was
1573 supplied to the configure script (fixes #46)
1574 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1575 instead of a fix value
1576 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1577 127 (solo mode) only kill voices if the respective mode really
1578 changed
1580 * LSCP server:
1581 - fixed compile time error for old Bison versions
1582 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1583 - parser now supports extended ASCII character set
1584 (up to ASCII code 255, i.e. includes now umlauts and accents)
1585 - filename arguments in LSCP commands now allow to use escape
1586 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1587 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1588 code value like \xf2) (fixes bug #24)
1589 - the following LSCP commands now also support escape sequences for at
1590 least one of their text-based parameters (i.e. name, description):
1597 - returns verbose syntax errors (line and column where syntax error
1598 occured, the unexpected character and the actually expected, possible
1599 character(s), the latter only if less than 5 possibilities)
1600 - made sure that LSCP syntax is not affected by gigedit locale
1601 settings
1602 - bugfix regarding strings parameter lists: all comma separated lists
1603 of strings were treated as being one string containing commas
1604 (fixes #57)
1606 * Bug fixes:
1607 - fixed crash occurring on certain LSCP scripts (Bug 39)
1608 - another thread safety fix for lscp "load engine" and "set
1609 channel audio output device"
1610 - fixed a crash which occurs when reassigning the same engine
1611 on a sampler channel with connected MIDI device
1612 - fixed a crash which occurs when changing the number of ports of a MIDI
1613 device connected to a sampler channel to number less then or equal
1614 to the index of the port to which the sampler channel is connected.
1615 - The previous bindings were not been disconnected when altering
1616 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1617 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1618 - The active stream/voice count statistic was incorrect.
1619 - notification events were not been sent for some sampler
1620 channel changes
1621 - added default min and max values to restrict the number of allowed
1622 audio output channels and MIDI input ports
1623 - the connection to the PCM interface is now closed when destroying
1624 an audio output device
1625 - files with slash in their path or filename could not be loaded
1627 * test cases:
1628 - updated and fixed (haven't been touched in a while)
1630 Version 0.4.0 (24 November 2006)
1632 * packaging changes:
1633 - changed deprecated copyright attribute to license; added ldconfig
1634 to post-(un)install steps; added devel package for liblinuxsampler;
1635 to linuxsampler.spec (RPM)
1636 - install necessary development header files for allowing 3rd party
1637 applications to link against liblinuxsampler
1638 - liblinuxsampler's API documentation can be generated with 'make docs'
1639 (Doxygen required)
1640 - added benchmark to automatically detect the best triangle LFO
1641 implementation (currently either an integer math solution or a
1642 di-harmonic approximation), automatic detection can be overriden
1643 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1644 configure script argument though (mandatory for cross-compilation)
1645 - do not automatically pick optimized gcc flags if the user already
1646 provided some on his own (as CXXFLAGS)
1647 - added compile time option to disable processing of All-Notes-Off MIDI
1648 messages
1649 - added compile time options to allow disabling the various audio and
1650 MIDI drivers
1651 - fixed automatic GCC CPU switch detection on PPC
1652 (patch by Ebrahim Mayat)
1654 * Gigasampler format engine:
1655 - extensive synthesis optimization
1656 (reimplementation of EGs and LFO(s), removed synthesis parameter
1657 prerendering and the synthesis parameter matrix in general, splitting
1658 each audio fragment into subfragments now where each subfragment uses
1659 constant pitch and filter coefficients. The volume coefficient is
1660 linearly interpolated inside a subfragment, unless
1661 --disable-interpolate-volume is set.)
1662 - fine tuning of the EG modulation parameters
1663 - improved filter cutoff calculation by adding support for the
1664 following gig parameters: Cutoff freq (used when no cutoff
1665 controller is defined), Control invert, Minimum cutoff, Velocity
1666 curve and Velocity range. The keyboard tracking now scales
1667 cutoff frequency instead of resonance.
1668 - added support for gig parameter Resonance.
1669 - fixed bug in sysex handling (patch by Juan Linietsky)
1670 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1671 which can be overridden with --enable-global-attenuation
1672 - EG fixes: made the length of "attack hold" stage more
1673 accurate. Release stage can now start before attack stage
1674 ends. Cancel release didn't work when sustain was zero. Attack
1675 time now has a minimal value to prevent clicks.
1676 - fixed pitch changes larger than one octave
1677 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1678 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1679 all modes can be altered via standard GM messages, that is CC5 for
1680 altering portamento time, CC65 for enabling / disabling portamento
1681 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1682 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1683 parameter) and crossfade
1684 - added support for the "attenuation controller threshold" gig
1685 parameter
1686 - added smoothing of volume changes caused by control change
1687 messages
1688 - sample loop parameters are now taken from the DimensionRegion
1689 instead of the wave chunk
1690 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1691 not equal to a power of two
1692 - reimplementation of the filter algorithm. The new filter is more
1693 accurate and supports all gig filter types, including bandreject
1694 and lowpass turbo.
1695 - real support for 24 bit samples - samples are not truncated to
1696 16 bits anymore
1697 - support for aftertouch (channel pressure, not polyphonic
1698 aftertouch)
1699 - LFO1 behaviour fixed (dampening from max volume instead of
1700 amplifying from 0)
1702 * LSCP server:
1703 - fixed application exit on broken pipe error (fixes bug #20)
1704 - fixed the notification messages delay due to lack of
1705 network activity (fixes bug #26)
1706 - fixed parser bug which occured on space(s) within device parameters
1709 * audio driver:
1710 - added aRts audio output driver (by no means RT safe)
1712 * MIDI driver:
1713 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1714 messages several times instead of once
1715 - API extension for MIDI drivers which already supply exact time stamps
1716 for events (i.e. for offline rendering based MIDI drivers)
1717 - added checks for bad MIDI data
1719 * linuxsampler application:
1720 - show available sampler engine types on startup
1722 * general changes:
1723 - support for muting sampler channels and solo mode of the same, two new
1724 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1725 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1726 introduced for this, the behavior is the same like on a mixer console
1727 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1728 --enable-process-muted-channels which can be used to enable the
1729 processing of muted channels.
1730 - support for sostenuto pedal
1731 - support for monitoring the total number of active voices
1734 - fixed some memory management errors
1735 - fixed some concurrency problems that could lead to crashes when
1736 LSCP commands were executed
1737 - fixed crash when instrument loading failed previously on the same
1738 sampler channel (fixes bug #36)
1740 Version 0.3.3 (15 July 2005)
1742 * packaging changes:
1743 - fixed compilation with gcc 4.0
1745 * Gigasampler format engine:
1746 - LFO preprocessing was performed even though the respective LFO was
1747 disabled by the instrument patch (minor efficiency fix)
1748 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1749 for volume ramp downs in the same fragment (needed for current voice
1750 stealing implementation) then simply inform the user with a warning
1751 about possible click sounds and reduce the volume ramp down
1752 appropriately instead of cancelling the audio device connection
1754 Version 0.3.2 (24 June 2005)
1756 * packaging changes:
1757 - updated autotools build files to compile on OS X
1758 (conditional compilation of CoreMIDI and MidiShare drivers)
1759 - hand-crafted assembly optimization code can be disabled with
1760 './configure --disable-asm' (definitely not recommended)
1761 - fixed 'make dist' rule to include all necessary files
1762 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1763 (due to 'dist-bzip2' automake option)
1765 * Gigasampler format engine:
1766 - support for the gig parameters for "release velocity response" curves
1767 - fine tuning of the EGADSR envelope
1768 - volume of release triggered samples now depends on note-on velocity,
1769 note length and gig parameter "release trigger decay" instead of
1770 note-off velocity.
1771 - revised voice stealing
1772 (fixes crash and endless loop caused by voice stealing)
1773 - don't reset scale tuning on instrument or audio output device change
1774 - handle key group conflicts right at the beginning of each fragment
1775 instead of when the respective voice is actually launched
1776 (fixes undefined behavior if stolen voices belonged to a key group -
1777 this case was followed by a "killed voice survived" error message)
1778 - fixed minor issue with null/silence samples
1779 (those stole voices even though they don't need a voice at all which
1780 resulted in "voice stealing didn't work out" messages)
1781 - don't reset volume, pan, pitch and MIDI controller values on
1782 instrument or audio output device change
1784 * LSCP server:
1785 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1786 - fixed LSCP event "CHANNEL_INFO" notification
1787 (e.g. did not notify on volume changes or MIDI program change events)
1789 * linuxsampler application:
1790 - added command line parameters --lscp-addr and --lscp-port to override
1791 default IP address and port of LSCP server
1793 Version 0.3.1 (24 May 2005)
1795 * initial release
