* NKSP language: Allow unary '+' operator.

* Test cases: Added NKSP tests for unary '+' operator.

* Bumped version (2.1.1.svn15).

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

529 - Mac OS X: Makefile fix for the install-strip target
530 - fixed compilation with gcc 4.7
531 - fixed configure script error with old autoconf versions

553 * general changes:
554 - Refactoring: moved the independent code from
555 the Gigasampler format engine to base classes
556 - command line option '--profile' is currently disabled, since the
557 respective profiling code is currently broken
558 - Introduced support for optional environment variable
559 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
560 where the sampler shall look for instrument editor plugins
561 (patch by Luis Garrido, slightly modified).
562 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
563 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
564 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
565 note (in this implementation of the sampler its simply hard routed to
566 the 1st effect send of the sampler channel, no matter what the actual
567 effect type is)
568 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
569 note (in this implementation of the sampler its simply hard routed to
570 the 2nd effect send of the sampler channel, no matter what the actual
571 effect type is)
572 - implemented support for internal LADSPA effects
573 - raised limit of program change queue from 100 to 512
574 (as suggested by Alex Stone)
575 - implemented sine LFO, pulse LFO and saw LFO
576 - experimental support for per voice equalization
577 - added command line option --exec-after-init
578 - Introduced new C++ API method:
579 EngineChannel::InstrumentFileName(int index)
580 allowing to retrieve the whole list of files used for the loaded
581 instrument on an engine channel (a.k.a. part). Some GigaStudio
582 instruments for example are splitted over several files like
583 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
584 - Added new C++ API method Sampler::GetGlobalMaxVoices().
585 - Added new C++ API method Sampler::GetGlobalMaxStreams().
586 - Added new C++ API method Sampler::SetGlobalMaxVoices().
587 - Added new C++ API method Sampler::SetGlobalMaxStreams().
588 - Various "const" and "restrict" optimizations.

590 applying panning, instead of using two separate pan functions in
591 series (#182)
592 - added a lock guard class for exception safe mutex handling and
593 used it everywhere appropriate
594 - Immediately apply scale tuning changes to active voices.
595 - Exposed scale tuning to C++ API (along to the already existing standard
596 SysEx way).
597 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
598 and broken for ppc64. (Seq_cst loads and stores are actually not
599 used in LS, so the bug wasn't noticable.)
600 - lsatomic.h: added ARMv7 support
601 - Added support for multiple MIDI input ports per sampler channel (and
602 added various new C++ methods for this new feature / design change, old
603 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
604 as deprecated but are still there and should provide full behavior
605 backward compatibility).
606 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
607 unsafe and caused compilation error with clang 2.x).
608 - Bugfix: only process the latest MIDI program change event.
609 - Introducing the LSCP shell, which provides convenient control of the
610 sampler from the command line by providing LSCP aware features.
611 - VirtualMidiDevice: Added support for program change.
612 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
613 - VirtualMidiDevice: Added support for pitch bend.
614 - Aftertouch: extended API to explicitly handle channel pressure and
615 polyphonic key pressure events (so far polyphonic pressure was not
616 supported at all, and channel pressure was rerouted as CC128 but not
617 used so far).
618 - Added initial support for real-time instrument scripts. The script VM
619 code is shared by all sampler engine implemementations, however only the
620 gig file format currently provides support for storing instrument scripts
621 (as LinuxSampler extension to the original GigaStudio 4 format).
623 * Gigasampler format engine:
624 - implemented the "round robin keyboard" dimension
625 - fixed round robin and random dimensions for cases when number of
626 dimension zones is not a power of two

628 key
629 - bugfix: pitch LFO controller "internal+aftertouch" was broken
630 - bugfix: filter keyboard tracking was broken
631 - filter performance fix (an unnecessary copy was made of the
632 filter parameters in each sub fragment)
633 - handle special case when pan parameter in gig file has max or
634 min value
635 - Exclusive Groups: don't ever stop voices of the same note,
636 doesn't sound naturally with a drumkit
637 - fixed EG1 modulation when attack or release is zero
638 - Fixed support for 'aftertouch' attenuation controller.
639 - Fixed crash that happened with velocity split sounds under certain
640 conditions (see also previous commit on libgig).
641 - fixed behaviour of filter LFO
643 * SFZ format engine:
644 - Initial implementation (not usable yet)
645 - added support for v2 multiple stage envelope generators
646 - added a fine-tuned v1 envelope generator instead of using the
647 one from the gig engine

652 - fixed error when unloading instrument with same sample used by
653 multiple regions
654 - added some opcode aliases, like loopmode for loop_mode, to be
655 more compatible

673 - added support for loop_mode=one_shot
674 - fixed playback of 16 bit wav files on big endian CPUs
675 - added support for Ogg Vorbis sample files
676 - use loop markers from sample file if loop_start and loop_end are
677 not set in sfz file
678 - implemeted filters. Filter types: lowpass, bandpass, bandreject
679 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
680 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
681 cutoff_cc, cutoff_chanaft.
682 - bugfix: zero ampeg_sustain didn't work

857 spawned for. This allows the instrument editors to interact more actively
858 with the sampler.
860 * MIDI driver:
861 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
862 the ALSA sequencer client name

945 be the case in other shells).
946 - Added support for moving cursor left/right with arrow keys.
947 - Added support for built-in LSCP reference documentation, which will
948 automatically show the relevant LSCP reference section on screen as soon

1006 channel to a different engine type
1007 - fixed crash when deleting a sampler channel or changing engine
1008 type while an instrument load was in progress
1009 - bugfix: playing a note while changing the instrument could cause
1010 a crash, or give "Handing back unknown region" error messages
1011 - bugfix: calling SET VOICES (which Fantasia does on start and
1012 refresh) could cause instruments to be unloaded
1013 - Mac OS X: fixed name collision of enum in EffectControl and
1014 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1015 - Mac OS X: fixed hanging threads
1016 - Windows: disabled the previous thread fix on non-Mac systems, as
1017 it caused hanging threads on Windows
1018 - Fixed possible crashes due to corrupted MIDI/audio device list
1019 after MIDI/audio device creation failure
1020 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1021 instruments were uselessly precached with zero samples, however it still
1022 took the full preloading time and on 1st program change the respective
1023 instrument was completely reloaded again.
1024 - fixed handling of rapid bank select and program change messages
1025 sent to the same sampler channel (patch from the Open Octave
1026 project, slightly adjusted)

1043 (labelled "Disk stream not available in time")
1044 - Update effects on sample rate & period size changes (to avoid
1045 crashes and noise on such transitions).
1046 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1047 (fixes #208)
1048 - Fixed bug in LSCP grammar definition which caused a statement like
1049 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1050 practically irrelevant, however it caused problems with the new LSCP
1051 shell's auto completion feature).
1052 - Fixed MIDI program change messages being ignored if quickly executed
1053 after each other (fixes #231).
1055 Version 1.0.0 (31 July 2009)
1057 * packaging changes:

1080 (fixes bug #70, patch by Ronald Baljeu)
1081 - fixed endless loop which occured when loading an instrument editor
1082 plugin DLL on Windows systems failed
1083 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1084 - optimized the SynchronizedConfig class so it doesn't wait
1085 unnecessarily long after an update

1087 events (e.g. to highlight the pressed keys on the virtual keyboard
1088 of gigedit)
1089 - added support for triggering notes by instrument editors (see above)
1090 - be verbose on DLL load errors (on Linux)
1091 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1092 is only used by very few systems, most pick the int math
1093 implementation, which is usually faster)
1094 - fixes for audio drivers with varying buffer sizes
1095 - experimental support for running LinuxSampler as a DSSI, LV2 and
1096 VST plugin
1097 - notification events for stream/voice count statistics are now sent

1101 - maximum voices and disk streams can now be altered at runtime
1102 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1103 - automatic stacktrace mechanism is now turned off by default and can
1104 be switched on by command line option "--stacktrace" (the automatic
1105 stacktrace mechanism seems to be broken on most systems at the moment)
1106 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1107 a pointer to the launched InstrumentEditor object
1108 - added optional 3rd party user data parameter for following
1109 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1110 InstrumentEditor::Launch(),
1111 InstrumentManager::LaunchInstrumentEditor()
1112 - theoretical fix: made SynchronizedConfig follow C++0x memory
1113 model more strictly
1114 - fixes for using large audio device buffers
1115 - Windows: add the installation directory to the DLL search path
1116 when loading an editor plugin (solves problems with VST and
1117 gigedit on systems with other GTK versions installed)
1118 - updated linuxsampler man page
1120 * audio driver:
1121 - removed the nonsense audio channel constraint (which was hard coded to
1122 max. 100 audio channels) for most audio drivers
1123 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1124 opposed to the LSCP specs
1125 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1126 reflected the wrong value
1127 - fixed a memory management bug in ASIO driver
1128 - Makefile fix: JACK_CFLAGS wasn't used
1129 - JACK: use jack_client_open instead of the deprecated
1130 jack_client_new

1136 win64)
1137 - VST: added support for sample rate and buffer size changes
1138 - VST: close editor (Fantasia) when the VST is removed
1139 - VST: avoid opening Fantasia more than once for each VST instance
1140 - VST: export main function as "main" on Linux too (fix for
1141 energyXT)
1142 - VST: changed number of output channels from one stereo to 16
1143 stereo
1144 - added channel routing, fxsends and midi maps to the settings
1145 stored in the plugin state
1146 - performance optimization of AudioChannel::MixTo() and
1147 AudioChannel::CopyTo() methods using GCC vector exensions
1148 (if available)
1149 - ASIO fixes: avoid initializing the device twice, avoid throwing
1150 exception when getting parameters from a disconnected device
1152 * MIDI driver:
1153 - added JACK MIDI driver
1154 - dispatch bank select as ordinary CC as well, the user might seriously
1155 want to (mis)use it for some purpose ("fixed" in all current MIDI
1156 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1157 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1158 CoreMidi or AU
1159 - fixed mingw-w64 compilation error in MME driver
1160 - made program change handling in MIDI thread real-time safe by
1161 moving the logic to a non-RT thread

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