Revision 3769 - (show annotations) (download)
Fri May 15 20:16:39 2020 UTC (3 years, 10 months ago) by schoenebeck
File size: 100072 byte(s)
Ref<> class: Use C++ atomics instead of C atomics (as some compilers seem
to be unable to mix C atomics with C++ code, and the generated result
should be binary identical anyway).

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

427 sub threads is 16-byte aligned
428 - fixed numerous compiler warnings
429 - Fixed invalid (note-on) event ID being assigned to new Note objects.
430 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
431 fixes potential undefined behavior.

433 have a valid sample mapped (fixes bug #252).
434 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.

438
439 * packaging changes:
440 - removed unnecessary dependency to libuuid
441 (originated by libgig's usage of it)
442 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
443 auto detect whether it (sh/c)ould output its messages in color.
444 - Debian: Fixed packaging error about invalid "Source-Version"
445 substitution variable.

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

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

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

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

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

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

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

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

664 configure
665 - Mac OS X: Makefile fix for the install-strip target
666 - fixed compilation with gcc 4.7
667 - fixed configure script error with old autoconf versions
668 - lsatomic.h: use gcc provided atomic functions if building with
669 gcc 4.7 and C++11
670 - modernized configure script
671 - fixed linkage error when building with
672 LDFLAGS="-Wl,--no-undefined" (#190)
673 - fixed compilation with Clang 3.2
674 - removed usage of deprecated Automake variable INCLUDES
675 - fixed building with C++11

681 on the process's main thread
682 - fixed build error on newer MinGW
683 - support building with older jack versions

687 in order to get rid of warnings from automake 1.14
688
689 * general changes:
690 - Refactoring: moved the independent code from
691 the Gigasampler format engine to base classes
692 - command line option '--profile' is currently disabled, since the
693 respective profiling code is currently broken
694 - Introduced support for optional environment variable
695 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
696 where the sampler shall look for instrument editor plugins
697 (patch by Luis Garrido, slightly modified).
698 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
699 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
700 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
701 note (in this implementation of the sampler its simply hard routed to
702 the 1st effect send of the sampler channel, no matter what the actual
703 effect type is)
704 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
705 note (in this implementation of the sampler its simply hard routed to
706 the 2nd effect send of the sampler channel, no matter what the actual
707 effect type is)
708 - implemented support for internal LADSPA effects
709 - raised limit of program change queue from 100 to 512
710 (as suggested by Alex Stone)
711 - implemented sine LFO, pulse LFO and saw LFO
712 - experimental support for per voice equalization
713 - added command line option --exec-after-init
714 - Introduced new C++ API method:
715 EngineChannel::InstrumentFileName(int index)
716 allowing to retrieve the whole list of files used for the loaded
717 instrument on an engine channel (a.k.a. part). Some GigaStudio
718 instruments for example are splitted over several files like
719 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
720 - Added new C++ API method Sampler::GetGlobalMaxVoices().
721 - Added new C++ API method Sampler::GetGlobalMaxStreams().
722 - Added new C++ API method Sampler::SetGlobalMaxVoices().
723 - Added new C++ API method Sampler::SetGlobalMaxStreams().
724 - Various "const" and "restrict" optimizations.
725 - all engines: add pan CC value to instrument pan parameter before
726 applying panning, instead of using two separate pan functions in
727 series (#182)
728 - added a lock guard class for exception safe mutex handling and
729 used it everywhere appropriate
730 - Immediately apply scale tuning changes to active voices.
731 - Exposed scale tuning to C++ API (along to the already existing standard
732 SysEx way).
733 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
734 and broken for ppc64. (Seq_cst loads and stores are actually not
735 used in LS, so the bug wasn't noticable.)
736 - lsatomic.h: added ARMv7 support
737 - Added support for multiple MIDI input ports per sampler channel (and
738 added various new C++ methods for this new feature / design change, old
739 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
740 as deprecated but are still there and should provide full behavior
741 backward compatibility).
742 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
743 unsafe and caused compilation error with clang 2.x).
744 - Bugfix: only process the latest MIDI program change event.
745 - Introducing the LSCP shell, which provides convenient control of the
746 sampler from the command line by providing LSCP aware features.
747 - VirtualMidiDevice: Added support for program change.
748 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
749 - VirtualMidiDevice: Added support for pitch bend.
750 - Aftertouch: extended API to explicitly handle channel pressure and
751 polyphonic key pressure events (so far polyphonic pressure was not
752 supported at all, and channel pressure was rerouted as CC128 but not
753 used so far).
754 - Added initial support for real-time instrument scripts. The script VM
755 code is shared by all sampler engine implemementations, however only the
756 gig file format currently provides support for storing instrument scripts
757 (as LinuxSampler extension to the original GigaStudio 4 format).
758
759 * Gigasampler format engine:
760 - implemented the "round robin keyboard" dimension
761 - fixed round robin and random dimensions for cases when number of
762 dimension zones is not a power of two
763 - made round robin use a counter for each region instead of each
764 key
765 - bugfix: pitch LFO controller "internal+aftertouch" was broken
766 - bugfix: filter keyboard tracking was broken
767 - filter performance fix (an unnecessary copy was made of the
768 filter parameters in each sub fragment)
769 - handle special case when pan parameter in gig file has max or
770 min value
771 - Exclusive Groups: don't ever stop voices of the same note,
772 doesn't sound naturally with a drumkit
773 - fixed EG1 modulation when attack or release is zero
774 - Fixed support for 'aftertouch' attenuation controller.
775 - Fixed crash that happened with velocity split sounds under certain
776 conditions (see also previous commit on libgig).
777 - fixed behaviour of filter LFO
778
779 * SFZ format engine:

788 - fixed error when unloading instrument with same sample used by
789 multiple regions
790 - added some opcode aliases, like loopmode for loop_mode, to be
791 more compatible
792 - added support for trigger=release and rt_decay
793 - added support for off_mode=normal

809 - added support for loop_mode=one_shot
810 - fixed playback of 16 bit wav files on big endian CPUs
811 - added support for Ogg Vorbis sample files
812 - use loop markers from sample file if loop_start and loop_end are
813 not set in sfz file
814 - implemeted filters. Filter types: lowpass, bandpass, bandreject
815 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
816 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
817 cutoff_cc, cutoff_chanaft.
818 - bugfix: zero ampeg_sustain didn't work

1007 the driver will automatically connect to other CoreMIDI clients' ports
1008 (e.g. external MIDI devices being attached to the Mac)
1009 - added support for MIDI note on velocity filter
1010 - CoreMIDI: fixed memory deallocation error
1011 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1145 - bugfix: playing a note while changing the instrument could cause
1146 a crash, or give "Handing back unknown region" error messages
1147 - bugfix: calling SET VOICES (which Fantasia does on start and
1148 refresh) could cause instruments to be unloaded
1149 - Mac OS X: fixed name collision of enum in EffectControl and
1150 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp

1181 crashes and noise on such transitions).
1182 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1183 (fixes #208)
1184 - Fixed bug in LSCP grammar definition which caused a statement like
1185 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1186 practically irrelevant, however it caused problems with the new LSCP
1187 shell's auto completion feature).
1188 - Fixed MIDI program change messages being ignored if quickly executed
1189 after each other (fixes #231).
1190
1191 Version 1.0.0 (31 July 2009)
1192
1193 * packaging changes:
1194 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1195 causing e.g. the libgig test to fail when
1196 "./configure --disable-jack-driver" was used
1197 (patch by Alexis Ballier)
1198 - fixed compilation with gcc 4.3
1199 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1203 - fixed building with libgig installed in a non-standard directory
1204 - minor fix in configure for mmsystem.h detection on MinGW
1205 - Windows: look for editor plugins and Fantasia using base
1206 directory of liblinuxsampler dll (look in the same directory and one
1207 directory above)
1208 - configure script fix: removed unconditional use of SSE
1209 - fixed building with sqlite installed in a non-standard directory
1210 - when cross-compiling, don't try to create instruments.db
1211 - fix for new mingw-w64 version, which has usleep
1212
1213 * general changes:
1214 - bugfix: on some POSIX systems instrument editor plugins refused to
1215 load as we used a non-portable Linux specific struct field
1216 (fixes bug #70, patch by Ronald Baljeu)
1217 - fixed endless loop which occured when loading an instrument editor
1218 plugin DLL on Windows systems failed
1219 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1220 - optimized the SynchronizedConfig class so it doesn't wait
1221 unnecessarily long after an update
1222 - added support for notifying instrument editors on note-on / note-off
1223 events (e.g. to highlight the pressed keys on the virtual keyboard
1224 of gigedit)
1225 - added support for triggering notes by instrument editors (see above)
1226 - be verbose on DLL load errors (on Linux)
1227 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1228 is only used by very few systems, most pick the int math
1229 implementation, which is usually faster)
1230 - fixes for audio drivers with varying buffer sizes
1231 - experimental support for running LinuxSampler as a DSSI, LV2 and
1232 VST plugin
1233 - notification events for stream/voice count statistics are now sent
1234 only when there are actual changes
1235 - added memory ordering constraints to improve stability on
1236 multi-core and multi-cpu systems
1237 - maximum voices and disk streams can now be altered at runtime
1238 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1239 - automatic stacktrace mechanism is now turned off by default and can
1240 be switched on by command line option "--stacktrace" (the automatic
1241 stacktrace mechanism seems to be broken on most systems at the moment)
1242 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1243 a pointer to the launched InstrumentEditor object
1244 - added optional 3rd party user data parameter for following
1245 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1246 InstrumentEditor::Launch(),
1247 InstrumentManager::LaunchInstrumentEditor()
1248 - theoretical fix: made SynchronizedConfig follow C++0x memory
1249 model more strictly
1250 - fixes for using large audio device buffers
1251 - Windows: add the installation directory to the DLL search path
1252 when loading an editor plugin (solves problems with VST and
1253 gigedit on systems with other GTK versions installed)
1254 - updated linuxsampler man page
1255
1256 * audio driver:
1257 - removed the nonsense audio channel constraint (which was hard coded to
1258 max. 100 audio channels) for most audio drivers
1259 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1260 opposed to the LSCP specs
1261 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1262 reflected the wrong value
1263 - fixed a memory management bug in ASIO driver
1264 - Makefile fix: JACK_CFLAGS wasn't used
1265 - JACK: use jack_client_open instead of the deprecated
1266 jack_client_new
1267 - added (experimental) CoreAudio driver
1268 - applied old fixes to the ASIO driver that were included in the
1269 previous binary release but accidentally never committed to CVS
1270 (fixes #117)
1271 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1272 win64)
1273 - VST: added support for sample rate and buffer size changes
1274 - VST: close editor (Fantasia) when the VST is removed
1275 - VST: avoid opening Fantasia more than once for each VST instance
1276 - VST: export main function as "main" on Linux too (fix for
1277 energyXT)
1278 - VST: changed number of output channels from one stereo to 16
1279 stereo
1280 - added channel routing, fxsends and midi maps to the settings
1281 stored in the plugin state
1282 - performance optimization of AudioChannel::MixTo() and
1283 AudioChannel::CopyTo() methods using GCC vector exensions
1284 (if available)
1285 - ASIO fixes: avoid initializing the device twice, avoid throwing
1286 exception when getting parameters from a disconnected device
1287
1288 * MIDI driver:
1289 - added JACK MIDI driver
1290 - dispatch bank select as ordinary CC as well, the user might seriously
1291 want to (mis)use it for some purpose ("fixed" in all current MIDI
1292 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1293 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1294 CoreMidi or AU
1295 - fixed mingw-w64 compilation error in MME driver
1296 - made program change handling in MIDI thread real-time safe by
1297 moving the logic to a non-RT thread
1298 - fixed minor memory leak in ALSA driver
1299
1300 * instruments database:
1301 - avoid time consuming samples scanning when adding instruments
1302 to the instruments database
1303 - added support for handling lost files in the instruments database
1304 - Implemented option for adding instruments in separate directories
1305 in the instruments database
1306 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1307 - work-around for missing fnmatch function on Windows to make
1308 instrument database compilable
1309 - added instrument database support on Windows
1310 works with both standalone mode and VST plugin.
1311 the instruments DB file is located in
1312 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1313 databases for each windows user
1314 if no DB is present it automatically creates the .linuxsampler subdir
1315 and then creates an empty DB
1316 - fixed recursive import, which was broken on Windows
1317
1318 * Gigasampler format engine:
1319 - fixed a memory leak that could happen when a channel was deleted
1320 while notes were playing
1321 - made it possible to load an instrument even if the audio thread
1322 isn't running
1323 - added partial support for the "Controller Triggered" MIDI rule,
1324 enough for piano gigs with pedal noise samples
1325 - minor fix: only mark FX sends as being modified if really the
1326 respective FX send MIDI controller was used
1327 - added support for GM global device volume SysEx message
1328 (can be selected at compile time to either apply globally to the
1329 whole sampler [default] or only to the sampler channels that are
1330 connected to the respective MIDI input port the SysEx message arrived
1331 on)
1332 - bugfix: notes triggered at position 0 in the audio buffer were
1333 sometimes wrongly killed in the same buffer, causing no sound to
1334 be played
1335 - added support for chromatic / drumkit mode Roland GS Sysex message
1336 which is usally used to switch a part between chromatic sounds and
1337 drumkit sounds (as opposed to their common default setting of MIDI
1338 part 10 being a drumkit part and all other ones chromatic parts), in
1339 LS however one can switch between the first 16 MIDI instrument maps
1340 defined for the sampler
1341 - made it possible to create multiple sample channels even if the
1342 audio thread isn't running
1343 - fixed crash when removing channel with active voices (#116)
1344 - bugfix: on sample reference changes (instrument editor), only
1345 un-cache the respective sample if it's really not used by any
1346 sampler engine anymore
1347 - re-cache samples in case they were changed by an instrument editor,
1348 e.g. when a sample was added while playing (#82)
1349 - fixed hanging notes which occured when note-off event had the exact
1350 same time stamp as the voice's note-on event and occured both in the
1351 same audio fragment cycle (fixes bug #112)
1352 - added support for the "fine tune" and "pitch bend range"
1353 instrument-level gig parameters
1354 - fixed minor artifacts in pitch bend handling
1355 - added support for GS Reset SysEx message
1356 - allow gig files to use unlimited downward pitch shifting
1357 - added a limit check for upward pitch shifting
1358 - bugfix: sometimes, when playing a note twice fast, the second
1359 note was silent
1360 - fixed crash happening when a pitch bend event arrived at the
1361 same time a new instrument was loading
1362
1363 * LSCP server:
1364 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1365 react on MIDI data arriving on certain sampler channels (so far only
1366 Note-On and Note-Off events are sent via this LSCP event)
1367 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1368 react on MIDI data arriving on certain MIDI input devices (so far only
1369 Note-On and Note-Off events are sent via this LSCP event)
1370 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1371 SET DB_INSTRUMENT FILE_PATH
1372 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1373 frontends to send MIDI messages to specific sampler channel
1374 - added two additional fields to GET FILE INSTRUMENT INFO command -
1375 KEY_BINDINGS and KEYSWITCH_BINDINGS
1376 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1377 was incorrect
1378 - Optimized the retrieval of the MIDI instrument mappings
1379 - added new LSCP command "SET VOICES" to globally alter the maximum
1380 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1381 be triggered respectively
1382 - added new LSCP command "SET STREAMS" to globally alter the maximum
1383 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1384 which will be triggered respectively
1385 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1386 a gigedit file dialog is opened)
1387 - close all connections when LSCPServer is deleted
1388 - hard close of all sockets on exit
1389 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1390 driver
1391
1392 * Bug fixes:
1393 - fixed a crash which occurs when removing a sampler channel waiting
1394 to start instrument loading after another channel
1395 - fixed a crash which occurs when removing a sampler channel with
1396 instrument loading in progress (bug #113)
1397 - fixed termination caused by uncaught exception when adding MIDI
1398 instrument with PERSISTENT load mode
1399 - fixed possible iterator invalidations when resetting the sampler
1400 - fixed memory leaks when issuing the following LSCP commands:
1401 GET AUDIO_OUTPUT_DRIVER INFO
1402 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1403 GET MIDI_INPUT_DRIVER INFO
1404 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1405 - fixed possible compilation error when sqlite is not present
1406 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1407 - fixed crash when changing the audio output device of a sampler
1408 channel with loaded instrument and start playing notes
1409 - fixed endless loop in Engine::SuspendAll() (bug #120)
1410 - fixed a low-level atomic load function that was broken on 64-bit
1411 PowerPC, which probably could cause crashes on that platform
1412 - fixed a memory management error which could cause a crash when a
1413 plugin was unloaded
1414 - bugfix: two private structs had the same name, which could cause
1415 problems if the linker chose the wrong constructor
1416 - fixed low-level ConditionServer usage bug that caused lockups on
1417 Windows
1418
1419
1420 Version 0.5.1 (6 December 2007)
1421
1422 * packaging changes:
1423 - added autoconf checks for pthread library
1424 - added autoconf check for pthread bug found on certain NPTL-enabled
1425 glibc versions (see Gentoo bug report #194076)
1426 - added autoconf checks for MS Windows
1427
1428 * general changes:
1429 - bugfix: the thread used by an editor plugin didn't die when the
1430 editor closed
1431 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1432 out all the space. operator--() did not apply size_mask after
1433 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1434 order to avoid problems with the _NonVolatileReader functions.
1435 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1436 GetWriteSpace(). Since this function is currently only used in
1437 the stream's qsort() compare function, it didn't trigger any
1438 bugs.
1439 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1440 24bit mode too. Faster method to read 24bit words on little
1441 endian machines (x86): replaced 3 byte reads + shifts with a 1
1442 unaligned 32bit read and shift
1443 - experimental support for MS Windows (MIDI input via MME, AUDIO
1444 output via ASIO)
1445 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1446 - support for monitoring the total number of active disk streams
1447 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1448 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1449
1450 * AUDIO driver:
1451 - added Windows ASIO low latency audio driver
1452
1453 * MIDI driver:
1454 - added MME Windows MIDI driver
1455
1456 * LSCP server:
1457 - added support for Windows style path / filenames, however with
1458 forward slash path separators instead of backslash
1459 (i.e. "C:/foo/bar.gig")
1460 - allow naughty liblscp to send non-string device parameters within
1461 apostrophes as well
1462 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1463 "LIST FILE INSTRUMENTS <file>" and
1464 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1465 about an arbitrary instrument file on the system where the sampler is
1466 running on
1467
1468 Version 0.5.0 (15 October 2007)
1469
1470 * packaging changes:
1471 - config.h is not going to be installed along with liblinuxsampler's
1472 API header files anymore
1473 - only the API relevant header (and source) files will be exported to
1474 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1475 - added completely new XCode project files for Mac OSX which is now
1476 capable to execute our autoconf environment, thus no need anymore
1477 to maintain the compile time configuration file (osx/version.h) for
1478 OSX manually (patch by Toshi Nagata)
1479 - fixed buggy boolean --enable-foo / --disable-foo configure script
1480 parameters
1481 - global.h now only covers global definitions that are needed for the
1482 C++ API header files, all implementation internal global definitions
1483 are now in global_private.h
1484 - atomic.h is not exposed to the C++ API anymore
1485 - no need to include config.h anymore for using LS's API header files
1486 - fixed warnings in API doc generation
1487
1488 * general changes:
1489 - replaced the old, confusing MIDI program change mechanism by a
1490 flexible MIDI instrument mapper which allows to map arbitrary
1491 (MIDI bank, MIDI program) pairs with arbitrary
1492 (engine type, instrument file, file index) triplets which will be
1493 loaded on the respective channel when such MIDI program change
1494 messages arrive, beside that, each entry allows to define a life-time
1495 strategy for the instrument, so the user can define whether the
1496 instrument should i.e. be permanently loaded (to be able to switch
1497 quickly among sounds) or i.e. loaded just on demand when the
1498 respective program change arrives (to safe RAM space), as well as a
1499 global volume factor for each entry, so the user can adjust the volume
1500 dynamic of his mapped instrument collection without having to modify
1501 the instrument files, also one can manage arbitrary amount of such
1502 MIDI instrument maps and assign each sampler channel individually
1503 a certain map, so that i.e. separation of normal instruments and
1504 drumkits is possible
1505 - new notification events for tracking changes to audio/MIDI devices,
1506 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1507 - sampler was limited to load max. 200 instruments in the background
1508 due to a constant size RingBuffer FIFO which is now replaced by a
1509 dynamic (unlimited) size std::list FIFO
1510 - added FX sends, these allow to route audio signals to arbitrary audio
1511 output channels for being processed by external effect processors
1512 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1513 controllers
1514 - global (sampler wide) volume can now be controlled at runtime
1515 - Implemented new, improved notification system
1516 - fixed compilation errors regarding OSX
1517 (patch by Toshi Nagata)
1518 - implemented instruments database
1519 - added support for escape sequences to the instruments database
1520 - added highly experimental support for on-the-fly instrument editing
1521 within the sampler's process (by using instrument editor plugins),
1522 you'll notice the new "Registered instrument editors:" message on
1523 startup, added a new LSCP command:
1524 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1525 to spawn a matching instrument editor for the instrument on the
1526 given sampler channel, the plugin path can be overridden at compile
1527 time with ./configure --enable-plugin-dir=/some/dir
1528 - added experimental code for synchronizing instrument editors hosted
1529 in the sampler's process to safely edit instruments while playing
1530 without a crash (hopefully) by either suspending single regions
1531 wherever possible or if unavoidable whole engine(s)
1532 - fixed several issues in fundamental "Thread" class: set scheduling
1533 policy and priority on thread level, set a minimum stack size for
1534 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1535 threads simply inherited properties of starting thread instead of
1536 setting their own policy and priority
1537 - minor fix in our automatic stack trace mechanism on crashes, the
1538 main process did not wait for the stack trace process to finish
1539 its output
1540 - fixed some minor memory leaks
1541 - reenabled assembly features support, at the moment only for
1542 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1543 - minor assembly fix in x86 features detection (don't use the PIC
1544 register, to avoid relocations in the text segment at runtime)
1545 - POSIX callback functions of Thread.h are hidden
1546
1547 * MIDI driver:
1548 - dispatch bank select (MSB and LSB) messages
1549
1550 * audio driver:
1551 - the ALSA audio output driver parameters now reflect the correct
1552 parameter value ranges for the respective selected sound card
1553 (patch by Till Wimmer, a bit fixed and extended)
1554
1555 * Gigasampler format engine:
1556 - if a filter is used and EG2 finishes before EG1, let the voice
1557 die when EG2 has finished (this fixes a problem with clicks and
1558 voice starvation for some gigs)
1559 - playback is no longer disabled during instrument loading
1560 - all notes playing on a channel that changes its instrument keep
1561 playing with the old instrument until they get a note off
1562 command
1563 - EG fix: a release value of zero could cause noises or crash
1564 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1565 - EG fine tuning: when attack is zero the EG starts at a level
1566 above max sustain level, which means that there is a decay phase
1567 even if sustain is 100%
1568 - more EG fixes: the level could sometimes go below zero and cause
1569 noises or crashes
1570 - minor fix of EGDecay (patch by Toshi Nagata)
1571 - fixed compiler error when --enable-override-filter-type was
1572 supplied to the configure script (fixes #46)
1573 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1574 instead of a fix value
1575 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1576 127 (solo mode) only kill voices if the respective mode really
1577 changed
1578
1579 * LSCP server:
1580 - fixed compile time error for old Bison versions
1581 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1582 - parser now supports extended ASCII character set
1583 (up to ASCII code 255, i.e. includes now umlauts and accents)
1584 - filename arguments in LSCP commands now allow to use escape
1585 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1586 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1587 code value like \xf2) (fixes bug #24)
1588 - the following LSCP commands now also support escape sequences for at
1589 least one of their text-based parameters (i.e. name, description):
1590 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1591 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1592 "SET DB_INSTRUMENT_DIRECTORY NAME",
1593 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1594 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1595 "FIND DB_INSTRUMENT_DIRECTORIES"
1596 - returns verbose syntax errors (line and column where syntax error
1597 occured, the unexpected character and the actually expected, possible
1598 character(s), the latter only if less than 5 possibilities)
1599 - made sure that LSCP syntax is not affected by gigedit locale
1600 settings
1601 - bugfix regarding strings parameter lists: all comma separated lists
1602 of strings were treated as being one string containing commas
1603 (fixes #57)
1604
1605 * Bug fixes:
1606 - fixed crash occurring on certain LSCP scripts (Bug 39)
1607 - another thread safety fix for lscp "load engine" and "set
1608 channel audio output device"
1609 - fixed a crash which occurs when reassigning the same engine
1610 on a sampler channel with connected MIDI device
1611 - fixed a crash which occurs when changing the number of ports of a MIDI
1612 device connected to a sampler channel to number less then or equal
1613 to the index of the port to which the sampler channel is connected.
1614 - The previous bindings were not been disconnected when altering
1615 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1616 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1617 - The active stream/voice count statistic was incorrect.
1618 - notification events were not been sent for some sampler
1619 channel changes
1620 - added default min and max values to restrict the number of allowed
1621 audio output channels and MIDI input ports
1622 - the connection to the PCM interface is now closed when destroying
1623 an audio output device
1624 - files with slash in their path or filename could not be loaded
1625
1626 * test cases:
1627 - updated and fixed (haven't been touched in a while)
1628
1629 Version 0.4.0 (24 November 2006)
1630
1631 * packaging changes:
1632 - changed deprecated copyright attribute to license; added ldconfig
1633 to post-(un)install steps; added devel package for liblinuxsampler;
1634 to linuxsampler.spec (RPM)
1635 - install necessary development header files for allowing 3rd party
1636 applications to link against liblinuxsampler
1637 - liblinuxsampler's API documentation can be generated with 'make docs'
1638 (Doxygen required)
1639 - added benchmark to automatically detect the best triangle LFO
1640 implementation (currently either an integer math solution or a
1641 di-harmonic approximation), automatic detection can be overriden
1642 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1643 configure script argument though (mandatory for cross-compilation)
1644 - do not automatically pick optimized gcc flags if the user already
1645 provided some on his own (as CXXFLAGS)
1646 - added compile time option to disable processing of All-Notes-Off MIDI
1647 messages
1648 - added compile time options to allow disabling the various audio and
1649 MIDI drivers
1650 - fixed automatic GCC CPU switch detection on PPC
1651 (patch by Ebrahim Mayat)
1652
1653 * Gigasampler format engine:
1654 - extensive synthesis optimization
1655 (reimplementation of EGs and LFO(s), removed synthesis parameter
1656 prerendering and the synthesis parameter matrix in general, splitting
1657 each audio fragment into subfragments now where each subfragment uses
1658 constant pitch and filter coefficients. The volume coefficient is
1659 linearly interpolated inside a subfragment, unless
1660 --disable-interpolate-volume is set.)
1661 - fine tuning of the EG modulation parameters
1662 - improved filter cutoff calculation by adding support for the
1663 following gig parameters: Cutoff freq (used when no cutoff
1664 controller is defined), Control invert, Minimum cutoff, Velocity
1665 curve and Velocity range. The keyboard tracking now scales
1666 cutoff frequency instead of resonance.
1667 - added support for gig parameter Resonance.
1668 - fixed bug in sysex handling (patch by Juan Linietsky)
1669 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1670 which can be overridden with --enable-global-attenuation
1671 - EG fixes: made the length of "attack hold" stage more
1672 accurate. Release stage can now start before attack stage
1673 ends. Cancel release didn't work when sustain was zero. Attack
1674 time now has a minimal value to prevent clicks.
1675 - fixed pitch changes larger than one octave
1676 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1677 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1678 all modes can be altered via standard GM messages, that is CC5 for
1679 altering portamento time, CC65 for enabling / disabling portamento
1680 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1681 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1682 parameter) and crossfade
1683 - added support for the "attenuation controller threshold" gig
1684 parameter
1685 - added smoothing of volume changes caused by control change
1686 messages
1687 - sample loop parameters are now taken from the DimensionRegion
1688 instead of the wave chunk
1689 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1690 not equal to a power of two
1691 - reimplementation of the filter algorithm. The new filter is more
1692 accurate and supports all gig filter types, including bandreject
1693 and lowpass turbo.
1694 - real support for 24 bit samples - samples are not truncated to
1695 16 bits anymore
1696 - support for aftertouch (channel pressure, not polyphonic
1697 aftertouch)
1698 - LFO1 behaviour fixed (dampening from max volume instead of
1699 amplifying from 0)
1700
1701 * LSCP server:
1702 - fixed application exit on broken pipe error (fixes bug #20)
1703 - fixed the notification messages delay due to lack of
1704 network activity (fixes bug #26)
1705 - fixed parser bug which occured on space(s) within device parameters
1706 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1707
1708 * audio driver:
1709 - added aRts audio output driver (by no means RT safe)
1710
1711 * MIDI driver:
1712 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1713 messages several times instead of once
1714 - API extension for MIDI drivers which already supply exact time stamps
1715 for events (i.e. for offline rendering based MIDI drivers)
1716 - added checks for bad MIDI data
1717
1718 * linuxsampler application:
1719 - show available sampler engine types on startup
1720
1721 * general changes:
1722 - support for muting sampler channels and solo mode of the same, two new
1723 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1724 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1725 introduced for this, the behavior is the same like on a mixer console
1726 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1727 --enable-process-muted-channels which can be used to enable the
1728 processing of muted channels.
1729 - support for sostenuto pedal
1730 - support for monitoring the total number of active voices
1731 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1732 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1733 - fixed some memory management errors
1734 - fixed some concurrency problems that could lead to crashes when
1735 LSCP commands were executed
1736 - fixed crash when instrument loading failed previously on the same
1737 sampler channel (fixes bug #36)
1738
1739 Version 0.3.3 (15 July 2005)
1740
1741 * packaging changes:
1742 - fixed compilation with gcc 4.0
1743
1744 * Gigasampler format engine:
1745 - LFO preprocessing was performed even though the respective LFO was
1746 disabled by the instrument patch (minor efficiency fix)
1747 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1748 for volume ramp downs in the same fragment (needed for current voice
1749 stealing implementation) then simply inform the user with a warning
1750 about possible click sounds and reduce the volume ramp down
1751 appropriately instead of cancelling the audio device connection
1752
1753 Version 0.3.2 (24 June 2005)
1754
1755 * packaging changes:
1756 - updated autotools build files to compile on OS X
1757 (conditional compilation of CoreMIDI and MidiShare drivers)
1758 - hand-crafted assembly optimization code can be disabled with
1759 './configure --disable-asm' (definitely not recommended)
1760 - fixed 'make dist' rule to include all necessary files
1761 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1762 (due to 'dist-bzip2' automake option)
1763
1764 * Gigasampler format engine:
1765 - support for the gig parameters for "release velocity response" curves
1766 - fine tuning of the EGADSR envelope
1767 - volume of release triggered samples now depends on note-on velocity,
1768 note length and gig parameter "release trigger decay" instead of
1769 note-off velocity.
1770 - revised voice stealing
1771 (fixes crash and endless loop caused by voice stealing)
1772 - don't reset scale tuning on instrument or audio output device change
1773 - handle key group conflicts right at the beginning of each fragment
1774 instead of when the respective voice is actually launched
1775 (fixes undefined behavior if stolen voices belonged to a key group -
1776 this case was followed by a "killed voice survived" error message)
1777 - fixed minor issue with null/silence samples
1778 (those stole voices even though they don't need a voice at all which
1779 resulted in "voice stealing didn't work out" messages)
1780 - don't reset volume, pan, pitch and MIDI controller values on
1781 instrument or audio output device change
1782
1783 * LSCP server:
1784 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1785 - fixed LSCP event "CHANNEL_INFO" notification
1786 (e.g. did not notify on volume changes or MIDI program change events)
1787
1788 * linuxsampler application:
1789 - added command line parameters --lscp-addr and --lscp-port to override
1790 default IP address and port of LSCP server
1791
1792 Version 0.3.1 (24 May 2005)
1793
1794 * initial release
