File size: 88614 byte(s)
* NKSP language: Fixed assignment to array variables which was
  broken by floating point support introduction (svn r3573).

* Test cases: Added NKSP int array and real array tests for value
  assignment and initialization of arrays.

* Bumped version (2.1.1.svn11).

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
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
142 * test cases:
143 - Fixed compiler errors in test cases.
144 - Updated README for how to compile & run test cases.
145 - Updated test case
146 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
147 expected behaviour of the Mutex class implementation (recursive
148 mutex type).
149 - Added test cases for NKSP core language aspects and core built-in
150 functions.
151 - Fixed thread tests segfaulting on Linux.
152 - NKSP: Added real number test cases for built-in functions exit(),
153 int_to_real(), real(), real_to_int() and int(), as well as for the
154 plus, minus and negate language operators.
155 - Added massive amount of NKSP test cases for standard measuring units and
156 'final' operator usage cases.
157 - Added NKSP test cases for (floating point tolerance aware) real number
158 equalness / unequalness comparison.
159 - Added NKSP int array and real array tests for value assignment and
160 initialization of arrays.
161
162 Version 2.1.1 (27 Jul 2019)
163
164 * Real-time instrument scripts:
165 - Fixed behavior of built-in NKSP functions change_sustain(),
166 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
167 and change_cutoff_release().
168
169 * general changes:
170 - Only play release trigger samples on sustain pedal up if this behaviour
171 was explicitly requested by the instrument (otherwise only on note-off).
172 - Fixed compiler warnings.
173 - Fixed compilation error when cross-compiling to Mac.
174 - FX Sends: Provide more useful error messages on routing problems
175 (see bug #169).
176 - LSCP doc: Be more clear describing the two distinct approaches
177 of using external vs. internal effects (see bug #169).
178 - "optional" class: Fixed comparison operators.
179
180 * Gigasampler/GigaStudio format engine:
181 - Format extension: If requested by instrument then don't play release
182 trigger sample on note-off events.
183
184 * SFZ format engine:
185 - Fixed memory leak when releasing samples
186 (fixes bug #307, patch by Jacek Roszkowski)
187 - Fixed potential crash when a sample is shared by more than one region
188 (fixes bug #308, patch by Jacek Roszkowski).
189 - Opcode 'sample': Added support for built-in sample '*silence'
190 (fixes bug #310, patch by Jacek Roszkowski).
191
192 Version 2.1.0 (25 Nov 2017)
193
194 * SFZ format engine:
195 - added support for <global>, <master> and #define (patch by Alby M)
196 - Removed code duplication in SFZ file loading code.
197 - Added support for sfz extension opcode 'script' which may be used to
198 load real-time instrument script file (NKSP script language).
199 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
200 - Fixed unintended volume fade-in of voices under certain conditions.
201 - sfz parser: allow missing space between header and opcode
202
203 * Gigasampler/GigaStudio format engine:
204 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
205 cutoff settings.
206 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
207 all if an up-pitch of more than 40 semi tones was requested (I don't
208 think there is any stock gig sound that requires this behavior to
209 resemble its original sound).
210 - Added support for controlling whether the individual EGADSR stages may
211 be aborted (as LinuxSampler extension to the original GigaStudio 4
212 format).
213
214 * general changes:
215 - fixed printf type errors (mostly in debug messages)
216 - use unique_ptr instead of auto_ptr when building with C++11
217 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
218 allowing to sort data efficiently in real-time safe manner.
219 - RTList class: added methods for moving/inserting elements to arbitrary
220 position within a list.
221 - RTList class: added method fromPtr() for creating an Iterator object from
222 a raw element pointer.
223 - Attempt to partly fix resetting engine channels vs. resetting engine, an
224 overall cleanup of the Reset*(), ConnectAudioDevice(),
225 DisconnectAudioDevice() API methods would still be desirable though,
226 because the current situation is still inconsistent and error prone.
227 - Active voices are now internally grouped to "Note" objects, instead of
228 being directly assigned to a keyboard key. This allows more fine graded
229 processing of voices, which is i.e. required for certain instrument
230 script features.
231 - Fix: Release trigger voices were not spawned on sustain pedal up
232 (CC #64) events.
233 - Fix: Release trigger voices can now also distinguish correctly between
234 note-off and sustain pedal up events.
235 - All engines: Increased ramp speed of volume smoother and pan smoother
236 (while slow rate of crossfade smoother is preserved) to allow quick
237 volume and pan changes by instrument scripts for instance.
238 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
239 properly and thus were ignored for certain uses.
240 - Added new C++ API method
241 VirtualMidiDevice::SendChannelPressureToSampler().
242 - windows, 32-bit: fixed potential crashes by making sure the stack in
243 sub threads is 16-byte aligned
244 - fixed numerous compiler warnings
245 - Fixed invalid (note-on) event ID being assigned to new Note objects.
246 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
247 fixes potential undefined behavior.
248 - Fixed Note object leak when triggering notes on keys which did not
249 have a valid sample mapped (fixes bug #252).
250 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
251 - linuxsampler binary fix: option --create-instruments-db ignored
252 subsequent optional argument due to glibc's implementation oddity
253 which expects a "=" sign, but no space between them.
254
255 * packaging changes:
256 - removed unnecessary dependency to libuuid
257 (originated by libgig's usage of it)
258 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
259 auto detect whether it (sh/c)ould output its messages in color.
260 - Debian: Fixed packaging error about invalid "Source-Version"
261 substitution variable.
262 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
263 - Debian: Added build dependency to libsqlite3-dev for building
264 linuxsampler with instruments DB support.
265
266 * Real-time instrument scripts:
267 - Implemented scheduler for delayed MIDI events and for suspended scripts.
268 - Built-in script function "wait()": implemented support for function's
269 "duration-us" argument, thus scripts using this function are now
270 correctly resumed after the requested amount of microseconds.
271 - Built-in script function "play_note()": implemented support for
272 function's "duration-us" argument, thus notes triggered with this
273 argument are now correctly released after the requested amount of
274 microseconds.
275 - Fix: script events were not cleared when engine channel was reset,
276 potentially causing undefined behavior.
277 - Fixed crash which happened when trying to reference an undeclared
278 variable.
279 - Built-in script function "play_note()": Added support for passing
280 special value -1 for "duration-us" argument, which will cause the
281 triggered note to be released once the original note was released.
282 - Instrument script classes now exported with the liblinuxsampler C++ API.
283 - Added new API method ScriptVM::syntaxHighlighting() which provides
284 a convenient syntax highlighting backend for external instrument
285 script editor applications.
286 - Added new C++ API class "ScriptVMFactory".
287 - Extended parser issues to provide not only first line and first
288 column, but also last line and last column of issue (thus marking
289 the precise span of the issue within the source code).
290 - Reload script automatically after being modified by an instrument
291 editor.
292 - NKSP language grammar correction: allow empty event handler bodies
293 like "on note end on".
294 - Implemented built-in script function "change_vol()".
295 - Implemented built-in script function "change_tune()".
296 - Implemented built-in script function "change_pan()".
297 - Implemented built-in script function "change_cutoff()".
298 - Implemented built-in script function "change_reso()".
299 - Implemented built-in script function "event_status()".
300 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
301 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
302 "event_status()" function.
303 - NKSP language: Added support for bitwise operators ".or.", ".and."
304 and ".not.".
305 - NKSP language scanner: Fixed IDs matching to require at least one
306 character (i.e. when matching function names or variable names).
307 - NKSP language scanner: disabled unusued rules.
308 - Fixed behavior of play_note() and note_off() functions which must
309 be distinguished engine internally from "real" MIDI note on/off
310 events in order to avoid misbehaviors like hanging notes.
311 - Implemented built-in script variable "$KSP_TIMER".
312 - Implemented built-in script variable "$NKSP_REAL_TIMER".
313 - Implemented built-in script variable "$NKSP_PERF_TIMER".
314 - Implemented built-in script variable "$ENGINE_UPTIME".
315 - Implemented built-in script function "inc()".
316 - Implemented built-in script function "dec()".
317 - NKSP language fix: division expressions were evaluated too often.
318 - NKSP language fix: string concatenation operator was right
319 associative instead of left (to right).
320 - NKSP language correction: allow empty statements in entire language
321 (i.e. "if end if").
322 - Implemented built-in script function "stop_wait()".
323 - Implemented built-in script variable "$NI_CALLBACK_ID".
324 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
325 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
326 - Added support for read-only built-in variables (respectively
327 handled by the script parser).
328 - Added built-in script constant "$NI_CB_TYPE_INIT".
329 - Added built-in script constant "$NI_CB_TYPE_NOTE".
330 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
331 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
332 - NKSP Language: Added support for user defined script functions.
333 - Implemented built-in script function "change_attack()".
334 - Implemented built-in script function "change_decay()".
335 - Implemented built-in script function "change_release()".
336 - Fixed all change_*() built-in script functions to apply their
337 synthesis parameter changes immediately in case the respective note
338 was triggered at the same time, instead of scheduling the parameter
339 change, especially because it would cause some parameter types's
340 changes either to be ramped (i.e. change_vol()) or other types even
341 to have not effect at all (i.e. change_attack()).
342 - Implemented built-in script function "sh_left()".
343 - Implemented built-in script function "sh_right()".
344 - Implemented built-in script function "min()".
345 - Implemented built-in script function "max()".
346 - NKSP Fix: "init" event handler was not always executed when a script
347 was loaded.
348 - NKSP built-in wait() script function: abort script execution if
349 a negative or zero wait time was passed as argument (since this is
350 a common indication of a bug either of the script or even of the
351 engine, which could lead to RT instability or even worse).
352 - ScriptVM: Implemented automatic suspension of RT safety
353 threatening scripts.
354 - Provide more user friendly error messages on syntax errors.
355 - Fixed NKSP parser warning "Not a statement" when assigning an
356 initializer list to an array variable.
357 - Implemented built-in script array variable "%ALL_EVENTS".
358 - Implemented built-in script function "in_range()".
359 - Implemented built-in script function "change_amp_lfo_depth()".
360 - Implemented built-in script function "change_amp_lfo_freq()".
361 - Implemented built-in script function "change_pitch_lfo_depth()".
362 - Implemented built-in script function "change_pitch_lfo_freq()".
363 - Implemented built-in script function "change_vol_time()".
364 - Implemented built-in script function "change_tune_time()".
365 - Implemented built-in script function "fade_in()".
366 - Implemented built-in script function "fade_out()".
367 - Fixed acceptance of wrong data type of parameters passed to built-in
368 script functions "change_vol()", "change_tune()", "change_pan()",
369 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
370 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
371 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
372 - Added built-in script function "get_event_par()" and implemented some
373 of its possible parameter selections.
374 - Added built-in script function "set_event_par()" and implemented some
375 of its possible parameter selections.
376 - Fixed a bunch of scheduler time related bugs.
377 - Fixed polyphonic variables not being reset to zero after usage.
378 - Built-in "ignore_event()" function: argument is now optional, like with
379 built-in function "ignore_controller()".
380 - Implemented built-in script function "change_velo()".
381 - Implemented built-in script function "change_note()".
382 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
383 intuitive behavior if used in combination with "change_vol_time()" or
384 "change_tune_time()" respectively: now tuning/volume changes are only
385 assigned (without delay) immediately to a new note if the respective
386 timing function has not been called before, otherwise the volume/tuning
387 changes are automatically faded (before, only the event's time stamp was
388 relevant).
389 - Implemented built-in script function "array_equal()".
390 - Implemented built-in script function "search()".
391 - Implemented built-in script function "sort()".
392 - NKSP Fix: Never suspend "init" event handlers.
393 - Implemented built-in script function "same_region()" (currently only
394 available for gig format engine).
395 - Added built-in script constant "$NKSP_LINEAR".
396 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
397 - Implemented built-in script function "change_vol_curve()".
398 - Implemented built-in script function "change_tune_curve()".
399 - built-in "play_note()" function now supports a sample playback start
400 offset with argument 3, where special value -1 means to use the regular
401 sample offset as defined by the instrument file.
402 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
403 - Built-in variable $EVENT_NOTE is now a read-only variable.
404 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
405 - built-in "play_note()" function now accepts -2 for its fourth argument
406 (note duration) which means the life time of the note shall be sticked
407 to the requested note number of argument 1.
408 - Fix: built-in "play_note()" function now returns 0 as result value if
409 -1 was passed for its fourth argument (note duration) and the respective
410 parent note is already gone.
411 - Implemented built-in script function "change_play_pos()".
412 - NKSP language: Added support for user declared const array variables.
413 - NKSP language: Raise parser warning if array variable is accessed with
414 an index that exceeds the array's size.
415 - NKSP language fix: Unknown characters were not handled correctly.
416 - NKSP language: Added support for "synchronized .. end synchronized"
417 code blocks.
418 - Implemented built-in script function "abort()" which allows to abort
419 another script handler by passing its callback ID.
420 - Fixed potential memory access bug and potential undefined behavior of
421 "init" event handlers.
422 - Print a time stamp along to each call of built-in function "message()".
423 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
424 to retrieve all code blocks filtered out by the preprocessor.
425 - Added built-in script function "fork()".
426 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
427 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
428 - Fixed potential crash when accessing dynamic built-in array variables.
429 - Added built-in script function "callback_status()".
430 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
431 - Added built-in constant $CALLBACK_STATUS_QUEUE.
432 - Added built-in constant $CALLBACK_STATUS_RUNNING.
433 - Removed max. value limitation of built-in functions "change_attack()",
434 "change_decay()" and "change_release()" to i.e. allow passing 2000000
435 for doubling the respective time.

486 - modernized configure script
487 - fixed linkage error when building with
488 LDFLAGS="-Wl,--no-undefined" (#190)
489 - fixed compilation with Clang 3.2
490 - removed usage of deprecated Automake variable INCLUDES

504
505 * general changes:
506 - Refactoring: moved the independent code from
507 the Gigasampler format engine to base classes
508 - command line option '--profile' is currently disabled, since the
509 respective profiling code is currently broken
510 - Introduced support for optional environment variable
511 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
512 where the sampler shall look for instrument editor plugins
513 (patch by Luis Garrido, slightly modified).
514 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
515 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
516 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
517 note (in this implementation of the sampler its simply hard routed to
518 the 1st effect send of the sampler channel, no matter what the actual
519 effect type is)
520 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
521 note (in this implementation of the sampler its simply hard routed to
522 the 2nd effect send of the sampler channel, no matter what the actual
523 effect type is)
524 - implemented support for internal LADSPA effects
525 - raised limit of program change queue from 100 to 512
526 (as suggested by Alex Stone)
527 - implemented sine LFO, pulse LFO and saw LFO
528 - experimental support for per voice equalization
529 - added command line option --exec-after-init
530 - Introduced new C++ API method:
531 EngineChannel::InstrumentFileName(int index)
532 allowing to retrieve the whole list of files used for the loaded
533 instrument on an engine channel (a.k.a. part). Some GigaStudio
534 instruments for example are splitted over several files like
535 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
536 - Added new C++ API method Sampler::GetGlobalMaxVoices().
537 - Added new C++ API method Sampler::GetGlobalMaxStreams().
538 - Added new C++ API method Sampler::SetGlobalMaxVoices().
539 - Added new C++ API method Sampler::SetGlobalMaxStreams().
540 - Various "const" and "restrict" optimizations.
541 - all engines: add pan CC value to instrument pan parameter before
542 applying panning, instead of using two separate pan functions in
543 series (#182)
544 - added a lock guard class for exception safe mutex handling and
545 used it everywhere appropriate
546 - Immediately apply scale tuning changes to active voices.
547 - Exposed scale tuning to C++ API (along to the already existing standard
548 SysEx way).
549 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
550 and broken for ppc64. (Seq_cst loads and stores are actually not
551 used in LS, so the bug wasn't noticable.)
552 - lsatomic.h: added ARMv7 support
553 - Added support for multiple MIDI input ports per sampler channel (and
554 added various new C++ methods for this new feature / design change, old
555 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
556 as deprecated but are still there and should provide full behavior
557 backward compatibility).
558 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
559 unsafe and caused compilation error with clang 2.x).
560 - Bugfix: only process the latest MIDI program change event.
561 - Introducing the LSCP shell, which provides convenient control of the
562 sampler from the command line by providing LSCP aware features.
563 - VirtualMidiDevice: Added support for program change.
564 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
565 - VirtualMidiDevice: Added support for pitch bend.
566 - Aftertouch: extended API to explicitly handle channel pressure and
567 polyphonic key pressure events (so far polyphonic pressure was not
568 supported at all, and channel pressure was rerouted as CC128 but not
569 used so far).
570 - Added initial support for real-time instrument scripts. The script VM
571 code is shared by all sampler engine implemementations, however only the
572 gig file format currently provides support for storing instrument scripts
573 (as LinuxSampler extension to the original GigaStudio 4 format).
574
575 * Gigasampler format engine:
576 - implemented the "round robin keyboard" dimension

580 key
581 - bugfix: pitch LFO controller "internal+aftertouch" was broken
582 - bugfix: filter keyboard tracking was broken
583 - filter performance fix (an unnecessary copy was made of the
584 filter parameters in each sub fragment)
585 - handle special case when pan parameter in gig file has max or
586 min value
587 - Exclusive Groups: don't ever stop voices of the same note,
588 doesn't sound naturally with a drumkit
589 - fixed EG1 modulation when attack or release is zero
590 - Fixed support for 'aftertouch' attenuation controller.
591 - Fixed crash that happened with velocity split sounds under certain
592 conditions (see also previous commit on libgig).
593 - fixed behaviour of filter LFO
594
595 * SFZ format engine:

625 - added support for loop_mode=one_shot
626 - fixed playback of 16 bit wav files on big endian CPUs
627 - added support for Ogg Vorbis sample files
628 - use loop markers from sample file if loop_start and loop_end are
629 not set in sfz file

771 - Listen to all interfaces on Mac OS X (INADDR_ANY)
772 - VST bugfix: If the host called resume() before and after
773 changing sample rate or block size, the number of channels was
774 incorrectly set to two. This caused silence in Cubase 5.
775 - save engine type (gig, sfz or sf2) in plugin state
776 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
777 64 bit Windows

811
812 * MIDI driver:
813 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
814 the ALSA sequencer client name

820 which allows to retrieve the list of CoreMIDI clients / ports and to connect
821 to them a la JACK, via the usual sampler APIs
822 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
823 the driver will automatically connect to other CoreMIDI clients' ports
824 (e.g. external MIDI devices being attached to the Mac)
825 - added support for MIDI note on velocity filter
826 - CoreMIDI: fixed memory deallocation error
827 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
828 virtual keyboards in frontends / instrument editors being stuck.
829 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
830 - Implemented missing handling of MIDI "running status".
831 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
832 - MME bugfix: driver wasn't closed properly

957 - fixed crash which occurred when changing an already deployed sampler
958 channel to a different engine type
959 - fixed crash when deleting a sampler channel or changing engine
960 type while an instrument load was in progress
961 - bugfix: playing a note while changing the instrument could cause
962 a crash, or give "Handing back unknown region" error messages
963 - bugfix: calling SET VOICES (which Fantasia does on start and
964 refresh) could cause instruments to be unloaded
965 - Mac OS X: fixed name collision of enum in EffectControl and
966 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
967 - Mac OS X: fixed hanging threads
968 - Windows: disabled the previous thread fix on non-Mac systems, as
969 it caused hanging threads on Windows
970 - Fixed possible crashes due to corrupted MIDI/audio device list
971 after MIDI/audio device creation failure
972 - When creating MIDI instrument map entries with "PERSISTENT" type, the
973 instruments were uselessly precached with zero samples, however it still
974 took the full preloading time and on 1st program change the respective
975 instrument was completely reloaded again.
976 - fixed handling of rapid bank select and program change messages
977 sent to the same sampler channel (patch from the Open Octave
978 project, slightly adjusted)
979 - fixed crash when trying to create an effect instance with controls
980 which min and/or max values depend on the sample rate

993 playing a note in a key group
994 - fixed erroneous error message piping in VoiceBase.h
995 (labelled "Disk stream not available in time")
996 - Update effects on sample rate & period size changes (to avoid
997 crashes and noise on such transitions).
998 - ignore missing LADSPA paths without ignoring valid LADSPA paths
999 (fixes #208)
1000 - Fixed bug in LSCP grammar definition which caused a statement like
1001 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1002 practically irrelevant, however it caused problems with the new LSCP
1003 shell's auto completion feature).
1004 - Fixed MIDI program change messages being ignored if quickly executed
1005 after each other (fixes #231).
1006
1007 Version 1.0.0 (31 July 2009)
1008
1009 * packaging changes:
1010 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1011 causing e.g. the libgig test to fail when
1012 "./configure --disable-jack-driver" was used
1013 (patch by Alexis Ballier)
1014 - fixed compilation with gcc 4.3
1015 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1022 directory of liblinuxsampler dll (look in the same directory and one
1023 directory above)
1024 - configure script fix: removed unconditional use of SSE
1025 - fixed building with sqlite installed in a non-standard directory
1026 - when cross-compiling, don't try to create instruments.db
1027 - fix for new mingw-w64 version, which has usleep
1028
1029 * general changes:
1030 - bugfix: on some POSIX systems instrument editor plugins refused to
1031 load as we used a non-portable Linux specific struct field
1032 (fixes bug #70, patch by Ronald Baljeu)
1033 - fixed endless loop which occured when loading an instrument editor
1034 plugin DLL on Windows systems failed
1035 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1036 - optimized the SynchronizedConfig class so it doesn't wait
1037 unnecessarily long after an update
1038 - added support for notifying instrument editors on note-on / note-off
1039 events (e.g. to highlight the pressed keys on the virtual keyboard
1040 of gigedit)
1041 - added support for triggering notes by instrument editors (see above)
1042 - be verbose on DLL load errors (on Linux)
1043 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1044 is only used by very few systems, most pick the int math
1045 implementation, which is usually faster)
1046 - fixes for audio drivers with varying buffer sizes
1047 - experimental support for running LinuxSampler as a DSSI, LV2 and
1048 VST plugin
1049 - notification events for stream/voice count statistics are now sent
1050 only when there are actual changes
1051 - added memory ordering constraints to improve stability on
1052 multi-core and multi-cpu systems
1053 - maximum voices and disk streams can now be altered at runtime
1054 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1055 - automatic stacktrace mechanism is now turned off by default and can
1056 be switched on by command line option "--stacktrace" (the automatic
1057 stacktrace mechanism seems to be broken on most systems at the moment)
1058 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1059 a pointer to the launched InstrumentEditor object
1060 - added optional 3rd party user data parameter for following
1061 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1062 InstrumentEditor::Launch(),
1063 InstrumentManager::LaunchInstrumentEditor()
1064 - theoretical fix: made SynchronizedConfig follow C++0x memory
1065 model more strictly
1066 - fixes for using large audio device buffers
1067 - Windows: add the installation directory to the DLL search path
1068 when loading an editor plugin (solves problems with VST and
1069 gigedit on systems with other GTK versions installed)
1070 - updated linuxsampler man page
1071
1072 * audio driver:
1073 - removed the nonsense audio channel constraint (which was hard coded to
1074 max. 100 audio channels) for most audio drivers
1075 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1076 opposed to the LSCP specs
1077 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1078 reflected the wrong value
1079 - fixed a memory management bug in ASIO driver
1080 - Makefile fix: JACK_CFLAGS wasn't used
1081 - JACK: use jack_client_open instead of the deprecated
1082 jack_client_new
1083 - added (experimental) CoreAudio driver
1084 - applied old fixes to the ASIO driver that were included in the
1085 previous binary release but accidentally never committed to CVS
1086 (fixes #117)
1087 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1088 win64)
1089 - VST: added support for sample rate and buffer size changes
1090 - VST: close editor (Fantasia) when the VST is removed
1091 - VST: avoid opening Fantasia more than once for each VST instance
1092 - VST: export main function as "main" on Linux too (fix for
1093 energyXT)
1094 - VST: changed number of output channels from one stereo to 16
1095 stereo
1096 - added channel routing, fxsends and midi maps to the settings
1097 stored in the plugin state
1098 - performance optimization of AudioChannel::MixTo() and
1099 AudioChannel::CopyTo() methods using GCC vector exensions
1100 (if available)
1101 - ASIO fixes: avoid initializing the device twice, avoid throwing
1102 exception when getting parameters from a disconnected device
1103
1104 * MIDI driver:
1105 - added JACK MIDI driver
1106 - dispatch bank select as ordinary CC as well, the user might seriously
1107 want to (mis)use it for some purpose ("fixed" in all current MIDI
1108 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1109 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1110 CoreMidi or AU
1111 - fixed mingw-w64 compilation error in MME driver
1112 - made program change handling in MIDI thread real-time safe by
1113 moving the logic to a non-RT thread
1114 - fixed minor memory leak in ALSA driver
1115
1116 * instruments database:
1117 - avoid time consuming samples scanning when adding instruments
1118 to the instruments database
1119 - added support for handling lost files in the instruments database
1120 - Implemented option for adding instruments in separate directories
1121 in the instruments database
1122 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1123 - work-around for missing fnmatch function on Windows to make
1124 instrument database compilable
1125 - added instrument database support on Windows
1126 works with both standalone mode and VST plugin.
1127 the instruments DB file is located in
1128 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1129 databases for each windows user
1130 if no DB is present it automatically creates the .linuxsampler subdir
1131 and then creates an empty DB
1132 - fixed recursive import, which was broken on Windows
1133
1134 * Gigasampler format engine:
1135 - fixed a memory leak that could happen when a channel was deleted
1136 while notes were playing
1137 - made it possible to load an instrument even if the audio thread
1138 isn't running
1139 - added partial support for the "Controller Triggered" MIDI rule,
1140 enough for piano gigs with pedal noise samples
1141 - minor fix: only mark FX sends as being modified if really the
1142 respective FX send MIDI controller was used
1143 - added support for GM global device volume SysEx message
1144 (can be selected at compile time to either apply globally to the
1145 whole sampler [default] or only to the sampler channels that are
1146 connected to the respective MIDI input port the SysEx message arrived
1147 on)
1148 - bugfix: notes triggered at position 0 in the audio buffer were
1149 sometimes wrongly killed in the same buffer, causing no sound to
1150 be played
1151 - added support for chromatic / drumkit mode Roland GS Sysex message
1152 which is usally used to switch a part between chromatic sounds and
1153 drumkit sounds (as opposed to their common default setting of MIDI
1154 part 10 being a drumkit part and all other ones chromatic parts), in
1155 LS however one can switch between the first 16 MIDI instrument maps
1156 defined for the sampler
1157 - made it possible to create multiple sample channels even if the
1158 audio thread isn't running
1159 - fixed crash when removing channel with active voices (#116)
1160 - bugfix: on sample reference changes (instrument editor), only
1161 un-cache the respective sample if it's really not used by any
1162 sampler engine anymore
1163 - re-cache samples in case they were changed by an instrument editor,
1164 e.g. when a sample was added while playing (#82)
1165 - fixed hanging notes which occured when note-off event had the exact
1166 same time stamp as the voice's note-on event and occured both in the
1167 same audio fragment cycle (fixes bug #112)
1168 - added support for the "fine tune" and "pitch bend range"
1169 instrument-level gig parameters
1170 - fixed minor artifacts in pitch bend handling
1171 - added support for GS Reset SysEx message
1172 - allow gig files to use unlimited downward pitch shifting
1173 - added a limit check for upward pitch shifting
1174 - bugfix: sometimes, when playing a note twice fast, the second
1175 note was silent
1176 - fixed crash happening when a pitch bend event arrived at the
1177 same time a new instrument was loading
1178
1179 * LSCP server:
1180 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1181 react on MIDI data arriving on certain sampler channels (so far only
1182 Note-On and Note-Off events are sent via this LSCP event)
1183 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1184 react on MIDI data arriving on certain MIDI input devices (so far only
1185 Note-On and Note-Off events are sent via this LSCP event)
1186 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1187 SET DB_INSTRUMENT FILE_PATH
1188 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1189 frontends to send MIDI messages to specific sampler channel
1190 - added two additional fields to GET FILE INSTRUMENT INFO command -
1191 KEY_BINDINGS and KEYSWITCH_BINDINGS
1192 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1193 was incorrect
1194 - Optimized the retrieval of the MIDI instrument mappings
1195 - added new LSCP command "SET VOICES" to globally alter the maximum
1196 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1197 be triggered respectively
1198 - added new LSCP command "SET STREAMS" to globally alter the maximum
1199 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1200 which will be triggered respectively
1201 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1202 a gigedit file dialog is opened)
1203 - close all connections when LSCPServer is deleted
1204 - hard close of all sockets on exit
1205 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1206 driver
1207
1208 * Bug fixes:
1209 - fixed a crash which occurs when removing a sampler channel waiting
1210 to start instrument loading after another channel
1211 - fixed a crash which occurs when removing a sampler channel with
1212 instrument loading in progress (bug #113)
1213 - fixed termination caused by uncaught exception when adding MIDI
1214 instrument with PERSISTENT load mode
1215 - fixed possible iterator invalidations when resetting the sampler
1216 - fixed memory leaks when issuing the following LSCP commands:
1217 GET AUDIO_OUTPUT_DRIVER INFO
1218 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1219 GET MIDI_INPUT_DRIVER INFO
1220 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1221 - fixed possible compilation error when sqlite is not present
1222 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1223 - fixed crash when changing the audio output device of a sampler
1224 channel with loaded instrument and start playing notes
1225 - fixed endless loop in Engine::SuspendAll() (bug #120)
1226 - fixed a low-level atomic load function that was broken on 64-bit
1227 PowerPC, which probably could cause crashes on that platform
1228 - fixed a memory management error which could cause a crash when a
1229 plugin was unloaded
1230 - bugfix: two private structs had the same name, which could cause
1231 problems if the linker chose the wrong constructor
1232 - fixed low-level ConditionServer usage bug that caused lockups on
1233 Windows
1234
1235
1236 Version 0.5.1 (6 December 2007)
1237
1238 * packaging changes:
1239 - added autoconf checks for pthread library
1240 - added autoconf check for pthread bug found on certain NPTL-enabled
1241 glibc versions (see Gentoo bug report #194076)
1242 - added autoconf checks for MS Windows
1243
1244 * general changes:
1245 - bugfix: the thread used by an editor plugin didn't die when the
1246 editor closed
1247 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1248 out all the space. operator--() did not apply size_mask after
1249 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1250 order to avoid problems with the _NonVolatileReader functions.
1251 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1252 GetWriteSpace(). Since this function is currently only used in
1253 the stream's qsort() compare function, it didn't trigger any
1254 bugs.
1255 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1256 24bit mode too. Faster method to read 24bit words on little
1257 endian machines (x86): replaced 3 byte reads + shifts with a 1
1258 unaligned 32bit read and shift
1259 - experimental support for MS Windows (MIDI input via MME, AUDIO
1260 output via ASIO)
1261 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1262 - support for monitoring the total number of active disk streams
1263 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1264 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1265
1266 * AUDIO driver:
1267 - added Windows ASIO low latency audio driver
1268
1269 * MIDI driver:
1270 - added MME Windows MIDI driver
1271
1272 * LSCP server:
1273 - added support for Windows style path / filenames, however with
1274 forward slash path separators instead of backslash
1275 (i.e. "C:/foo/bar.gig")
1276 - allow naughty liblscp to send non-string device parameters within
1277 apostrophes as well
1278 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1279 "LIST FILE INSTRUMENTS <file>" and
1280 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1281 about an arbitrary instrument file on the system where the sampler is
1282 running on
1283
1284 Version 0.5.0 (15 October 2007)
1285
1286 * packaging changes:
1287 - config.h is not going to be installed along with liblinuxsampler's
1288 API header files anymore
1289 - only the API relevant header (and source) files will be exported to
1290 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1291 - added completely new XCode project files for Mac OSX which is now
1292 capable to execute our autoconf environment, thus no need anymore
1293 to maintain the compile time configuration file (osx/version.h) for
1294 OSX manually (patch by Toshi Nagata)
1295 - fixed buggy boolean --enable-foo / --disable-foo configure script
1296 parameters
1297 - global.h now only covers global definitions that are needed for the
1298 C++ API header files, all implementation internal global definitions
1299 are now in global_private.h
1300 - atomic.h is not exposed to the C++ API anymore
1301 - no need to include config.h anymore for using LS's API header files
1302 - fixed warnings in API doc generation
1303
1304 * general changes:
1305 - replaced the old, confusing MIDI program change mechanism by a
1306 flexible MIDI instrument mapper which allows to map arbitrary
1307 (MIDI bank, MIDI program) pairs with arbitrary
1308 (engine type, instrument file, file index) triplets which will be
1309 loaded on the respective channel when such MIDI program change
1310 messages arrive, beside that, each entry allows to define a life-time
1311 strategy for the instrument, so the user can define whether the
1312 instrument should i.e. be permanently loaded (to be able to switch
1313 quickly among sounds) or i.e. loaded just on demand when the
1314 respective program change arrives (to safe RAM space), as well as a
1315 global volume factor for each entry, so the user can adjust the volume
1316 dynamic of his mapped instrument collection without having to modify
1317 the instrument files, also one can manage arbitrary amount of such
1318 MIDI instrument maps and assign each sampler channel individually
1319 a certain map, so that i.e. separation of normal instruments and
1320 drumkits is possible
1321 - new notification events for tracking changes to audio/MIDI devices,
1322 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1323 - sampler was limited to load max. 200 instruments in the background
1324 due to a constant size RingBuffer FIFO which is now replaced by a
1325 dynamic (unlimited) size std::list FIFO
1326 - added FX sends, these allow to route audio signals to arbitrary audio
1327 output channels for being processed by external effect processors
1328 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1329 controllers
1330 - global (sampler wide) volume can now be controlled at runtime
1331 - Implemented new, improved notification system
1332 - fixed compilation errors regarding OSX
1333 (patch by Toshi Nagata)
1334 - implemented instruments database
1335 - added support for escape sequences to the instruments database
1336 - added highly experimental support for on-the-fly instrument editing
1337 within the sampler's process (by using instrument editor plugins),
1338 you'll notice the new "Registered instrument editors:" message on
1339 startup, added a new LSCP command:
1340 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1341 to spawn a matching instrument editor for the instrument on the
1342 given sampler channel, the plugin path can be overridden at compile
1343 time with ./configure --enable-plugin-dir=/some/dir
1344 - added experimental code for synchronizing instrument editors hosted
1345 in the sampler's process to safely edit instruments while playing
1346 without a crash (hopefully) by either suspending single regions
1347 wherever possible or if unavoidable whole engine(s)
1348 - fixed several issues in fundamental "Thread" class: set scheduling
1349 policy and priority on thread level, set a minimum stack size for
1350 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1351 threads simply inherited properties of starting thread instead of
1352 setting their own policy and priority
1353 - minor fix in our automatic stack trace mechanism on crashes, the
1354 main process did not wait for the stack trace process to finish
1355 its output
1356 - fixed some minor memory leaks
1357 - reenabled assembly features support, at the moment only for
1358 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1359 - minor assembly fix in x86 features detection (don't use the PIC
1360 register, to avoid relocations in the text segment at runtime)
1361 - POSIX callback functions of Thread.h are hidden
1362
1363 * MIDI driver:
1364 - dispatch bank select (MSB and LSB) messages
1365
1366 * audio driver:
1367 - the ALSA audio output driver parameters now reflect the correct
1368 parameter value ranges for the respective selected sound card
1369 (patch by Till Wimmer, a bit fixed and extended)
1370
1371 * Gigasampler format engine:
1372 - if a filter is used and EG2 finishes before EG1, let the voice
1373 die when EG2 has finished (this fixes a problem with clicks and
1374 voice starvation for some gigs)
1375 - playback is no longer disabled during instrument loading
1376 - all notes playing on a channel that changes its instrument keep
1377 playing with the old instrument until they get a note off
1378 command
1379 - EG fix: a release value of zero could cause noises or crash
1380 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1381 - EG fine tuning: when attack is zero the EG starts at a level
1382 above max sustain level, which means that there is a decay phase
1383 even if sustain is 100%
1384 - more EG fixes: the level could sometimes go below zero and cause
1385 noises or crashes
1386 - minor fix of EGDecay (patch by Toshi Nagata)
1387 - fixed compiler error when --enable-override-filter-type was
1388 supplied to the configure script (fixes #46)
1389 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1390 instead of a fix value
1391 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1392 127 (solo mode) only kill voices if the respective mode really
1393 changed
1394
1395 * LSCP server:
1396 - fixed compile time error for old Bison versions
1397 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1398 - parser now supports extended ASCII character set
1399 (up to ASCII code 255, i.e. includes now umlauts and accents)
1400 - filename arguments in LSCP commands now allow to use escape
1401 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1402 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1403 code value like \xf2) (fixes bug #24)
1404 - the following LSCP commands now also support escape sequences for at
1405 least one of their text-based parameters (i.e. name, description):
1406 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1407 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1408 "SET DB_INSTRUMENT_DIRECTORY NAME",
1409 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1410 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1411 "FIND DB_INSTRUMENT_DIRECTORIES"
1412 - returns verbose syntax errors (line and column where syntax error
1413 occured, the unexpected character and the actually expected, possible
1414 character(s), the latter only if less than 5 possibilities)
1415 - made sure that LSCP syntax is not affected by gigedit locale
1416 settings
1417 - bugfix regarding strings parameter lists: all comma separated lists
1418 of strings were treated as being one string containing commas
1419 (fixes #57)
1420
1421 * Bug fixes:
1422 - fixed crash occurring on certain LSCP scripts (Bug 39)
1423 - another thread safety fix for lscp "load engine" and "set
1424 channel audio output device"
1425 - fixed a crash which occurs when reassigning the same engine
1426 on a sampler channel with connected MIDI device
1427 - fixed a crash which occurs when changing the number of ports of a MIDI
1428 device connected to a sampler channel to number less then or equal
1429 to the index of the port to which the sampler channel is connected.
1430 - The previous bindings were not been disconnected when altering
1431 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1432 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1433 - The active stream/voice count statistic was incorrect.
1434 - notification events were not been sent for some sampler
1435 channel changes
1436 - added default min and max values to restrict the number of allowed
1437 audio output channels and MIDI input ports
1438 - the connection to the PCM interface is now closed when destroying
1439 an audio output device
1440 - files with slash in their path or filename could not be loaded
1441
1442 * test cases:
1443 - updated and fixed (haven't been touched in a while)
1444
1445 Version 0.4.0 (24 November 2006)
1446
1447 * packaging changes:
1448 - changed deprecated copyright attribute to license; added ldconfig
1449 to post-(un)install steps; added devel package for liblinuxsampler;
1450 to linuxsampler.spec (RPM)
1451 - install necessary development header files for allowing 3rd party
1452 applications to link against liblinuxsampler
1453 - liblinuxsampler's API documentation can be generated with 'make docs'
1454 (Doxygen required)
1455 - added benchmark to automatically detect the best triangle LFO
1456 implementation (currently either an integer math solution or a
1457 di-harmonic approximation), automatic detection can be overriden
1458 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1459 configure script argument though (mandatory for cross-compilation)
1460 - do not automatically pick optimized gcc flags if the user already
1461 provided some on his own (as CXXFLAGS)
1462 - added compile time option to disable processing of All-Notes-Off MIDI
1463 messages
1464 - added compile time options to allow disabling the various audio and
1465 MIDI drivers
1466 - fixed automatic GCC CPU switch detection on PPC
1467 (patch by Ebrahim Mayat)
1468
1469 * Gigasampler format engine:
1470 - extensive synthesis optimization
1471 (reimplementation of EGs and LFO(s), removed synthesis parameter
1472 prerendering and the synthesis parameter matrix in general, splitting
1473 each audio fragment into subfragments now where each subfragment uses
1474 constant pitch and filter coefficients. The volume coefficient is
1475 linearly interpolated inside a subfragment, unless
1476 --disable-interpolate-volume is set.)
1477 - fine tuning of the EG modulation parameters
1478 - improved filter cutoff calculation by adding support for the
1479 following gig parameters: Cutoff freq (used when no cutoff
1480 controller is defined), Control invert, Minimum cutoff, Velocity
1481 curve and Velocity range. The keyboard tracking now scales
1482 cutoff frequency instead of resonance.
1483 - added support for gig parameter Resonance.
1484 - fixed bug in sysex handling (patch by Juan Linietsky)
1485 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1486 which can be overridden with --enable-global-attenuation
1487 - EG fixes: made the length of "attack hold" stage more
1488 accurate. Release stage can now start before attack stage
1489 ends. Cancel release didn't work when sustain was zero. Attack
1490 time now has a minimal value to prevent clicks.
1491 - fixed pitch changes larger than one octave
1492 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1493 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1494 all modes can be altered via standard GM messages, that is CC5 for
1495 altering portamento time, CC65 for enabling / disabling portamento
1496 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1497 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1498 parameter) and crossfade
1499 - added support for the "attenuation controller threshold" gig
1500 parameter
1501 - added smoothing of volume changes caused by control change
1502 messages
1503 - sample loop parameters are now taken from the DimensionRegion
1504 instead of the wave chunk
1505 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1506 not equal to a power of two
1507 - reimplementation of the filter algorithm. The new filter is more
1508 accurate and supports all gig filter types, including bandreject
1509 and lowpass turbo.
1510 - real support for 24 bit samples - samples are not truncated to
1511 16 bits anymore
1512 - support for aftertouch (channel pressure, not polyphonic
1513 aftertouch)
1514 - LFO1 behaviour fixed (dampening from max volume instead of
1515 amplifying from 0)
1516
1517 * LSCP server:
1518 - fixed application exit on broken pipe error (fixes bug #20)
1519 - fixed the notification messages delay due to lack of
1520 network activity (fixes bug #26)
1521 - fixed parser bug which occured on space(s) within device parameters
1522 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1523
1524 * audio driver:
1525 - added aRts audio output driver (by no means RT safe)
1526
1527 * MIDI driver:
1528 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1529 messages several times instead of once
1530 - API extension for MIDI drivers which already supply exact time stamps
1531 for events (i.e. for offline rendering based MIDI drivers)
1532 - added checks for bad MIDI data
1533
1534 * linuxsampler application:
1535 - show available sampler engine types on startup
1536
1537 * general changes:
1538 - support for muting sampler channels and solo mode of the same, two new
1539 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1540 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1541 introduced for this, the behavior is the same like on a mixer console
1542 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1543 --enable-process-muted-channels which can be used to enable the
1544 processing of muted channels.
1545 - support for sostenuto pedal
1546 - support for monitoring the total number of active voices
1547 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1548 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1549 - fixed some memory management errors
1550 - fixed some concurrency problems that could lead to crashes when
1551 LSCP commands were executed
1552 - fixed crash when instrument loading failed previously on the same
1553 sampler channel (fixes bug #36)
1554
1555 Version 0.3.3 (15 July 2005)
1556
1557 * packaging changes:
1558 - fixed compilation with gcc 4.0
1559
1560 * Gigasampler format engine:
1561 - LFO preprocessing was performed even though the respective LFO was
1562 disabled by the instrument patch (minor efficiency fix)
1563 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1564 for volume ramp downs in the same fragment (needed for current voice
1565 stealing implementation) then simply inform the user with a warning
1566 about possible click sounds and reduce the volume ramp down
1567 appropriately instead of cancelling the audio device connection
1568
1569 Version 0.3.2 (24 June 2005)
1570
1571 * packaging changes:
1572 - updated autotools build files to compile on OS X
1573 (conditional compilation of CoreMIDI and MidiShare drivers)
1574 - hand-crafted assembly optimization code can be disabled with
1575 './configure --disable-asm' (definitely not recommended)
1576 - fixed 'make dist' rule to include all necessary files
1577 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1578 (due to 'dist-bzip2' automake option)
1579
1580 * Gigasampler format engine:
1581 - support for the gig parameters for "release velocity response" curves
1582 - fine tuning of the EGADSR envelope
1583 - volume of release triggered samples now depends on note-on velocity,
1584 note length and gig parameter "release trigger decay" instead of
1585 note-off velocity.
1586 - revised voice stealing
1587 (fixes crash and endless loop caused by voice stealing)
1588 - don't reset scale tuning on instrument or audio output device change
1589 - handle key group conflicts right at the beginning of each fragment
1590 instead of when the respective voice is actually launched
1591 (fixes undefined behavior if stolen voices belonged to a key group -
1592 this case was followed by a "killed voice survived" error message)
1593 - fixed minor issue with null/silence samples
1594 (those stole voices even though they don't need a voice at all which
1595 resulted in "voice stealing didn't work out" messages)
1596 - don't reset volume, pan, pitch and MIDI controller values on
1597 instrument or audio output device change
1598
1599 * LSCP server:
1600 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1601 - fixed LSCP event "CHANNEL_INFO" notification
1602 (e.g. did not notify on volume changes or MIDI program change events)
1603
1604 * linuxsampler application:
1605 - added command line parameters --lscp-addr and --lscp-port to override
1606 default IP address and port of LSCP server
1607
1608 Version 0.3.1 (24 May 2005)
1609
1610 * initial release
