File size: 93870 byte(s)
* Gig engine: Changed default wave form for all 3 LFOs to sine
  (instead of triangle; see discussion "GigaStudio LFO
  compatibility" on mailing list from 2019-09-26 for details).
* Bumped version (2.1.1.svn21).

1 schoenebeck 3548 Version SVN trunk (?)
2    
3     * general changes:
4     - Fixed compiler error in Pool.h.
5 schoenebeck 3581 - Require C++14 compiler support.
6 schoenebeck 3557 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 schoenebeck 3581 for checking in configure for C++14 support (as mandatory
8 schoenebeck 3557 requirement) and automatically adds compiler argument if required
9 schoenebeck 3581 (e.g. -std=C++14).
10 schoenebeck 3575 - 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 schoenebeck 3612 - Added public API C++ class "LFO", which is a cluster class encapsulating
14     all the sampler's LFO implementations to be used by 3rd party applications
15     (e.g. by Gigedit).
16     - Added int math square LFO implementation.
17     - Added int math saw LFO implementation.
18     - Added numeric complex nr sine LFO implementation.
19     - Marked class LFOTriangleDiHarmonic as deprecated
20     (will be removed in future).
21     - Added LFOAll.h which includes all LFO implementation's header files.
22 schoenebeck 3614 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23     LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24     SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25     SquareLFO -> LFOSquarePulse and separated the latter to its own header
26     file).
27     - Renamed type LFOSigned -> LFOTriangleSigned.
28     - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29 schoenebeck 3550
30 schoenebeck 3551 * Real-time instrument scripts:
31     - Added method ScriptVM::setExitResultEnabled() which allows to
32     explicitly enable the built-in exit() function to optionally accept
33     one function argument; the value of the passed exit() function
34     argument will then become available by calling
35     VMExecContext::exitResult() after script execution.
36 schoenebeck 3557 - 64 bit support for NKSP integer scripts variables (declare $foo).
37 schoenebeck 3561 - Variable names, function names and preprocessor condition names must start
38     with a regular character (a-z or A-Z); starting them with a digit or
39     underscore is not allowed.
40     - NKSP parser fix: equal comparison operator "=" and not equal comparison
41     operator "#" must only accept integer operands.
42     - NKSP language: Implemented support for standard units like Hertz, seconds,
43     Bel including support for metric unit prefixes; so one can now e.g.
44     conveniently use numbers in scripts like "5us" meaning "5 microseconds",
45     or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
46     "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
47     - NKSP language: Introduced "final" operator "!" which is specifically
48     intended for synthesis parameter values to denote that the synthesis
49     parameter value is intended to be the "final" value for that synthesis
50     parameter that should explicitly be used by the engine and thus causing
51     the sampler engine to ignore all other modulation sources for the same
52     synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
53     variable or formula with this new "!" operator the expression is marked as
54     being "final".
55 schoenebeck 3562 - NKSP script editor API: Added support for detecting standard unit tokens
56     and their potential metric prefix token.
57 schoenebeck 3573 - NKSP language: Added support for NKSP real number literals and
58     arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
59     - NKSP language: Added support for NKSP real number (floating point) script
60     variables (declare ~foo).
61     - NKSP language: Added support for NKSP real number (floating point) array
62     script variables (declare ?foo[]).
63     - Built-in script function "message()" accepts now real number argument as
64     well.
65     - Added built-in script function "real_to_int()" and its short hand form
66     "int()" for casting from real number to integer in NKSP scripts.
67     - Added built-in script function "int_to_real()" and its short hand form
68     "real()" for casting from integer to real number in NKSP scripts.
69 schoenebeck 3575 - Allow built-in exit() function to potentially accept real number type
70     argument as well.
71 schoenebeck 3577 - Built-in script functions may have a different return type depending on
72     the arguments passed to the function.
73     - Built-in script function "abs()" optionally accepts and returns real
74     number.
75     - Built-in script functions "min()" and "max()" optionally accept real
76     number arguments and return real number as result in that case.
77 schoenebeck 3581 - NKSP VM API: Allow units and 'final'ness to be returned as result from
78     built-in functions (added methods VMFunction::returnUnitType() and
79     VMFunction::returnsFinal() for that purpose which must be implemented by
80     built-in function implementations).
81     - NKSP language: Allow metric unit prefixes of numeric scalar and array
82     variables to be changed freely at runtime (unlike unit types like Hz etc.
83     which are still sticky, parse-time features of variables which cannot be
84     changed at runtime for the intentional sake of determinism).
85     - NKSP language: 'final' values are prohibited for array variables for now
86     (attempt causes a parsers error).
87     - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
88     conditions of runtime control structures like if(), while(), select()
89     (attempt causes a parser error).
90     - NKSP VM API: Allow built-in functions to perform their own, individual
91     parse time checks of arguments going to be passed to the function at
92     runtime (added method VMFunction::checkArgs() for that purpose).
93     - NKSP language: raise parser warning if only one operand of binary
94     operators (like logical 'or' comparison) contain a 'final' value (because
95     it would always yield in a 'final' result in such cases).
96     - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
97     different metric unit prefixes, which will behave as expected (e.g.
98     result of expression '1000us < 2ms' is true).
99     - NKSP language: Allow adding values with different metric unit prefixes
100     (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
101     - NKSP language: Allow subtracting values with different metric unit
102     prefixes (e.g. result of expression '1ms - 20us' is '980us').
103     - NKSP language: Allow multiplying with any metric unit prefixes
104     (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
105     with unit types on both sides (e.g. '2s * 2s') is still prohibited since
106     we don't have any considerable practical use for a term like '4s^2'
107     (hence any attempt multiplying two unit types still causes parser error).
108     - NKSP language: Allow dividing by any metric unit prefixes and allow
109     division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
110     yields in unit free result '8'). So this is now a way to cast units away
111     e.g. for passing the result to other expressions, certain function calls
112     or variables which are not accepting any units (or that specific unit).
113     - NKSP language: integer arrays and real number arrays can now be converted
114     to strings (e.g. for dumping their content with message() calls for
115     script debugging purposes).
116     - NKSP language: expressions and variables with units are now correctly
117     casted to strings (e.g. with message() calls).
118     - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
119     unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
120     floating point tolerances into account.
121     - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
122     VMScalarNumberExpr::evalCastReal().
123     - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
124     'VMIntArrayExpr' and 'VMRealArrayExpr'.
125     - NKSP VM API: replaced all unitPrefix() (parse time) methods by
126     unitFactor() (runtime) methods.
127     - Built-in function "exit()" supports now returning units and 'final'ness
128     for test cases.
129     - The following built-in functions support now units as well: "abs()",
130     "random()", "inc()", "dec()", "in_range()", "min()", "max()",
131     "real_to_int()", "int()", "int_to_real()" and "real()".
132     - Built-in functions "array_equal()", "search()" and "sort()" support now
133     real number arrays (correctly) as well.
134     - Added individual parse time checks of arguments to be passed to built-in
135     functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
136     "array_equal()" and "search()" specific for their individual purposes.
137 schoenebeck 3582 - NKSP VM refactoring: Renamed all methods, functions and classes matching
138     pattern *ScalarNumber* to simply *Number* (that is i.e. classes
139     VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
140     ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
141     NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
142     method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
143     isScalarNumber() -> isNumber()).
144 schoenebeck 3584 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
145     evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
146     evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
147     as convenient methods for automatically converting values to expected
148     metric value basis.
149     - Built-in function "wait()" accepts now both integers and real numbers as
150     argument.
151 schoenebeck 3585 - NKSP VM API cleanup: Get rid of legacy method
152     VMFunction::argType(vmint iArg) which was already superseded by its new
153     replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
154     - NKSP parser: if wrong argument type was passed to a built-in function and
155     that built-in function accepts more than one data type for the argument,
156     then show all supported data types as parser error message.
157 schoenebeck 3587 - Built-in function "play_note()" accepts now real numbers and seconds as
158     unit type as well for its 3rd and 4th function arguments.
159     - The following built-in functions accept now real numbers as well for their
160     2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
161     "change_attack()", "change_decay()", "change_release()",
162     "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
163     "change_cutoff_sustain()", "change_cutoff_release()",
164     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
165     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
166     "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
167     - Fixed built-in function "change_play_pos()" not having accepted metric
168     prefixes at all.
169 schoenebeck 3588 - Fixed the following built-in functions having misinterpreted values given
170     with unit type (for their 2nd argument) as if they were relative values
171     (that is as if they were passed without a unit type): "change_attack()",
172     "change_decay()", "change_release()", "change_cutoff_attack()",
173     "change_cutoff_decay()", "change_cutoff_release()".
174     - Fixed the following built-in functions having applied completely wrong
175     'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
176     respective EGs being their modulation sink assume uint data type with
177     value range 0..1000 instead of 0.0..1.0.
178     - Added individual parse-time checks of function arguments for the following
179     built-in functions: "play_note()", "note_off()", "set_event_mark()",
180     "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
181     "change_decay()", "change_release()", "change_cutoff_attack()",
182     "change_cutoff_decay()", "change_cutoff_release()",
183     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
184     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
185     "change_pan_time()".
186     - Don't abort function call if unit type was used and at the same time
187     'final' operator was omitted for the primary value argument of the
188     following built-in functions: "change_cutoff()", "change_attack()",
189     "change_decay()", "change_release()", "change_cutoff_attack()",
190     "change_cutoff_decay()", "change_cutoff_release()",
191     "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
192     "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
193     "change_pan_time()", instead imply 'final'ness at runtime and raise an
194     appropriate parser warning at parse time.
195 schoenebeck 3590 - Added built-in real number functions "round()", "ceil()", "floor()",
196     "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
197     "cos()", "tan()", "asin()", "acos()", "atan()".
198     - Added built-in script real number constant "~NI_MATH_PI".
199     - Added built-in script real number constant "~NI_MATH_E".
200 schoenebeck 3592 - NKSP language: Allow unary '+' operator.
201 schoenebeck 3551
202 schoenebeck 3550 * test cases:
203 schoenebeck 3548 - Fixed compiler errors in test cases.
204     - Updated README for how to compile & run test cases.
205     - Updated test case
206     MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
207     expected behaviour of the Mutex class implementation (recursive
208     mutex type).
209 schoenebeck 3551 - Added test cases for NKSP core language aspects and core built-in
210     functions.
211 schoenebeck 3552 - Fixed thread tests segfaulting on Linux.
212 schoenebeck 3575 - NKSP: Added real number test cases for built-in functions exit(),
213     int_to_real(), real(), real_to_int() and int(), as well as for the
214     plus, minus and negate language operators.
215 schoenebeck 3581 - Added massive amount of NKSP test cases for standard measuring units and
216     'final' operator usage cases.
217     - Added NKSP test cases for (floating point tolerance aware) real number
218     equalness / unequalness comparison.
219 schoenebeck 3586 - Added NKSP int array and real array tests for value assignment and
220     initialization of arrays.
221 schoenebeck 3590 - Added NKSP test cases for built-in functions "round()", "ceil()",
222     "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
223     "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
224 schoenebeck 3592 - Added NKSP test cases for unary '+' operator.
225 schoenebeck 3548
226 schoenebeck 3611 * GigaStudio/Gigasampler format engine:
227     - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
228     behaviour for start_level_mid.
229 schoenebeck 3615 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
230     level (see discussion "GigaStudio LFO compatibility" on mailing list
231     from 2019-09-26 for details).
232 schoenebeck 3616 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
233     see discussion "GigaStudio LFO compatibility" on mailing list from
234     2019-09-26 for details).
235 schoenebeck 3611
236 persson 3593 * SFZ format engine:
237     - Fixed support for regions with loccN/hiccN conditions on more than one
238     MIDI controller.
239    
240 schoenebeck 3612 * Benchmarks:
241     - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
242     algorithm (since result of 2nd run was not accumulated).
243     - Added benchmark for saw wave (benchmarks/saw.cpp).
244     - Added benchmark for sine wave (benchmarks/sine.cpp).
245     - Added benchmark for square wave (benchmarks/square.cpp).
246     - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
247     which are large enough on modern systems.
248    
249 schoenebeck 3537 Version 2.1.1 (27 Jul 2019)
250 schoenebeck 3381
251     * Real-time instrument scripts:
252     - Fixed behavior of built-in NKSP functions change_sustain(),
253     change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
254     and change_cutoff_release().
255    
256 schoenebeck 3444 * general changes:
257     - Only play release trigger samples on sustain pedal up if this behaviour
258     was explicitly requested by the instrument (otherwise only on note-off).
259 persson 3455 - Fixed compiler warnings.
260     - Fixed compilation error when cross-compiling to Mac.
261 schoenebeck 3501 - FX Sends: Provide more useful error messages on routing problems
262     (see bug #169).
263     - LSCP doc: Be more clear describing the two distinct approaches
264     of using external vs. internal effects (see bug #169).
265 schoenebeck 3514 - "optional" class: Fixed comparison operators.
266 schoenebeck 3444
267 schoenebeck 3448 * Gigasampler/GigaStudio format engine:
268     - Format extension: If requested by instrument then don't play release
269     trigger sample on note-off events.
270    
271 schoenebeck 3487 * SFZ format engine:
272     - Fixed memory leak when releasing samples
273     (fixes bug #307, patch by Jacek Roszkowski)
274 schoenebeck 3492 - Fixed potential crash when a sample is shared by more than one region
275     (fixes bug #308, patch by Jacek Roszkowski).
276 schoenebeck 3497 - Opcode 'sample': Added support for built-in sample '*silence'
277     (fixes bug #310, patch by Jacek Roszkowski).
278 schoenebeck 3487
279 schoenebeck 3372 Version 2.1.0 (25 Nov 2017)
280 persson 2837
281 persson 2856 * SFZ format engine:
282     - added support for <global>, <master> and #define (patch by Alby M)
283 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
284     - Added support for sfz extension opcode 'script' which may be used to
285     load real-time instrument script file (NKSP script language).
286 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
287 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
288 persson 3291 - sfz parser: allow missing space between header and opcode
289 persson 2856
290 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
291 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
292     cutoff settings.
293 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
294     all if an up-pitch of more than 40 semi tones was requested (I don't
295     think there is any stock gig sound that requires this behavior to
296     resemble its original sound).
297 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
298     be aborted (as LinuxSampler extension to the original GigaStudio 4
299     format).
300 schoenebeck 3072
301 persson 2837 * general changes:
302     - fixed printf type errors (mostly in debug messages)
303 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
304 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
305     allowing to sort data efficiently in real-time safe manner.
306     - RTList class: added methods for moving/inserting elements to arbitrary
307     position within a list.
308     - RTList class: added method fromPtr() for creating an Iterator object from
309     a raw element pointer.
310     - Attempt to partly fix resetting engine channels vs. resetting engine, an
311     overall cleanup of the Reset*(), ConnectAudioDevice(),
312     DisconnectAudioDevice() API methods would still be desirable though,
313     because the current situation is still inconsistent and error prone.
314 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
315     being directly assigned to a keyboard key. This allows more fine graded
316     processing of voices, which is i.e. required for certain instrument
317     script features.
318 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
319     (CC #64) events.
320     - Fix: Release trigger voices can now also distinguish correctly between
321     note-off and sustain pedal up events.
322 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
323     (while slow rate of crossfade smoother is preserved) to allow quick
324     volume and pan changes by instrument scripts for instance.
325 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
326     properly and thus were ignored for certain uses.
327 schoenebeck 3018 - Added new C++ API method
328     VirtualMidiDevice::SendChannelPressureToSampler().
329 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
330     sub threads is 16-byte aligned
331 schoenebeck 3054 - fixed numerous compiler warnings
332 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
333 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
334     fixes potential undefined behavior.
335 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
336     have a valid sample mapped (fixes bug #252).
337     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
338 schoenebeck 3354 - linuxsampler binary fix: option --create-instruments-db ignored
339     subsequent optional argument due to glibc's implementation oddity
340     which expects a "=" sign, but no space between them.
341 persson 2837
342 schoenebeck 2866 * packaging changes:
343     - removed unnecessary dependency to libuuid
344     (originated by libgig's usage of it)
345 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
346     auto detect whether it (sh/c)ould output its messages in color.
347 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
348     substitution variable.
349     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
350 schoenebeck 3354 - Debian: Added build dependency to libsqlite3-dev for building
351     linuxsampler with instruments DB support.
352 schoenebeck 2866
353 schoenebeck 2871 * Real-time instrument scripts:
354     - Implemented scheduler for delayed MIDI events and for suspended scripts.
355     - Built-in script function "wait()": implemented support for function's
356     "duration-us" argument, thus scripts using this function are now
357     correctly resumed after the requested amount of microseconds.
358     - Built-in script function "play_note()": implemented support for
359     function's "duration-us" argument, thus notes triggered with this
360     argument are now correctly released after the requested amount of
361     microseconds.
362     - Fix: script events were not cleared when engine channel was reset,
363     potentially causing undefined behavior.
364     - Fixed crash which happened when trying to reference an undeclared
365     variable.
366 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing

368     triggered note to be released once the original note was released.
369 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
370     - Added new API method ScriptVM::syntaxHighlighting() which provides
371     a convenient syntax highlighting backend for external instrument
372     script editor applications.
373 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
374     - Extended parser issues to provide not only first line and first
375     column, but also last line and last column of issue (thus marking
376     the precise span of the issue within the source code).
377 schoenebeck 2902 - Reload script automatically after being modified by an instrument
378     editor.
379 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
380     like "on note end on".

389     "event_status()" function.
390     - NKSP language: Added support for bitwise operators ".or.", ".and."
391     and ".not.".
392     - NKSP language scanner: Fixed IDs matching to require at least one
393     character (i.e. when matching function names or variable names).
394     - NKSP language scanner: disabled unusued rules.
395 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
396     be distinguished engine internally from "real" MIDI note on/off
397     events in order to avoid misbehaviors like hanging notes.

403     - Implemented built-in script function "dec()".
404     - NKSP language fix: division expressions were evaluated too often.
405     - NKSP language fix: string concatenation operator was right
406     associative instead of left (to right).
407 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
408     (i.e. "if end if").
409 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
410     - Implemented built-in script variable "$NI_CALLBACK_ID".
411     - Implemented built-in script variable "$NI_CALLBACK_TYPE".

423 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
424     synthesis parameter changes immediately in case the respective note
425     was triggered at the same time, instead of scheduling the parameter
426     change, especially because it would cause some parameter types's
427     changes either to be ramped (i.e. change_vol()) or other types even
428     to have not effect at all (i.e. change_attack()).
429 schoenebeck 2965 - Implemented built-in script function "sh_left()".

433 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
434     was loaded.
435     - NKSP built-in wait() script function: abort script execution if
436     a negative or zero wait time was passed as argument (since this is
437     a common indication of a bug either of the script or even of the
438     engine, which could lead to RT instability or even worse).
439 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
440     threatening scripts.
441 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
442 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
443     initializer list to an array variable.

455     script functions "change_vol()", "change_tune()", "change_pan()",
456     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
457     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
458     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
459 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
460     of its possible parameter selections.
461     - Added built-in script function "set_event_par()" and implemented some
462     of its possible parameter selections.
463 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
464 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
465 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
466     built-in function "ignore_controller()".
467 schoenebeck 3214 - Implemented built-in script function "change_velo()".
468     - Implemented built-in script function "change_note()".
469 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
470     intuitive behavior if used in combination with "change_vol_time()" or
471     "change_tune_time()" respectively: now tuning/volume changes are only
472     assigned (without delay) immediately to a new note if the respective
473     timing function has not been called before, otherwise the volume/tuning
474     changes are automatically faded (before, only the event's time stamp was
475     relevant).
476 schoenebeck 3221 - Implemented built-in script function "array_equal()".
477     - Implemented built-in script function "search()".
478     - Implemented built-in script function "sort()".
479     - NKSP Fix: Never suspend "init" event handlers.
480 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
481     available for gig format engine).
482 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
483     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
484     - Implemented built-in script function "change_vol_curve()".
485     - Implemented built-in script function "change_tune_curve()".
486 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
487     offset with argument 3, where special value -1 means to use the regular
488     sample offset as defined by the instrument file.
489 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
490     - Built-in variable $EVENT_NOTE is now a read-only variable.
491     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
492     - built-in "play_note()" function now accepts -2 for its fourth argument
493     (note duration) which means the life time of the note shall be sticked
494     to the requested note number of argument 1.
495     - Fix: built-in "play_note()" function now returns 0 as result value if
496     -1 was passed for its fourth argument (note duration) and the respective
497     parent note is already gone.
498 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
499 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.

506     another script handler by passing its callback ID.
507 schoenebeck 3283 - Fixed potential memory access bug and potential undefined behavior of
508     "init" event handlers.
509 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
510     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
511     to retrieve all code blocks filtered out by the preprocessor.
512 schoenebeck 3293 - Added built-in script function "fork()".
513     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
514     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
515     - Fixed potential crash when accessing dynamic built-in array variables.
516 schoenebeck 3296 - Added built-in script function "callback_status()".
517     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
518     - Added built-in constant $CALLBACK_STATUS_QUEUE.
519     - Added built-in constant $CALLBACK_STATUS_RUNNING.
520 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
521     "change_decay()" and "change_release()" to i.e. allow passing 2000000
522     for doubling the respective time.
523 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
524     to a lexer start condition stack underrun.
525     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
526     USE_CODE_IF_NOT() preprocessor statements.
527 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
528     can be set to disable all subsequent built-in "message()" function calls
529     on preprocessor level.
530 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
531 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
532     to avoid the editor app to crash on ill-formed text input.
533 schoenebeck 3335 - Added built-in script function "change_pan_time()".
534     - Added built-in script function "change_pan_curve()".
535 schoenebeck 3360 - Added built-in script function "change_cutoff_attack()".
536     - Added built-in script function "change_cutoff_decay()".
537     - Added built-in script function "change_cutoff_sustain()".
538     - Added built-in script function "change_cutoff_release()".
539     - Added built-in script function "change_cutoff_lfo_depth()".
540     - Added built-in script function "change_cutoff_lfo_freq()".
541 schoenebeck 2871
542 schoenebeck 3050 * Instruments DB:
543     - Fixed memory access bug of general DB access code which lead to
544     undefined behavior.
545 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
546     - The instrument DB path of linuxsampler's --create-instruments-db argument
547     is now optional, if it is missing, then a default location is used.
548 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
549     - Added support for scanning Sound Font (.sf2) files.
550 schoenebeck 3101 - Fixed undefined DB transaction behavior.

561 persson 2185 - fixed compilation with gcc 4.6.1
562 persson 2203 - another "make dist" fix, for the LV2 plugin
563 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
564 persson 2197 - minor Makefile fix for building lscpparser when build and source
565     directories are separate
566 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
567     configure

588 persson 2519 - enabled automake 'subdir-objects' option and moved external
589     source references (vst, au, asio) from makefiles to cpp files,
590     in order to get rid of warnings from automake 1.14
591 persson 2382
592 persson 2086 * general changes:
593 iliev 2012 - Refactoring: moved the independent code from
594     the Gigasampler format engine to base classes
595 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
596     respective profiling code is currently broken
597 schoenebeck 2053 - Introduced support for optional environment variable
598     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
599     where the sampler shall look for instrument editor plugins
600     (patch by Luis Garrido, slightly modified).
601 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
602     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
603     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
604     note (in this implementation of the sampler its simply hard routed to
605     the 1st effect send of the sampler channel, no matter what the actual
606     effect type is)
607     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
608     note (in this implementation of the sampler its simply hard routed to
609     the 2nd effect send of the sampler channel, no matter what the actual
610     effect type is)
611 schoenebeck 2124 - implemented support for internal LADSPA effects
612 schoenebeck 2140 - raised limit of program change queue from 100 to 512
613     (as suggested by Alex Stone)
614 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
615 iliev 2296 - experimental support for per voice equalization
616 iliev 2306 - added command line option --exec-after-init
617 schoenebeck 2330 - Introduced new C++ API method:
618     EngineChannel::InstrumentFileName(int index)
619     allowing to retrieve the whole list of files used for the loaded
620     instrument on an engine channel (a.k.a. part). Some GigaStudio
621     instruments for example are splitted over several files like
622     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
623 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
624     - Added new C++ API method Sampler::GetGlobalMaxStreams().
625     - Added new C++ API method Sampler::SetGlobalMaxVoices().
626     - Added new C++ API method Sampler::SetGlobalMaxStreams().
627 schoenebeck 2377 - Various "const" and "restrict" optimizations.
628 persson 2382 - all engines: add pan CC value to instrument pan parameter before
629     applying panning, instead of using two separate pan functions in
630     series (#182)
631 persson 2427 - added a lock guard class for exception safe mutex handling and
632     used it everywhere appropriate
633 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
634     - Exposed scale tuning to C++ API (along to the already existing standard
635     SysEx way).
636 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
637     and broken for ppc64. (Seq_cst loads and stores are actually not
638     used in LS, so the bug wasn't noticable.)
639     - lsatomic.h: added ARMv7 support
640 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
641     added various new C++ methods for this new feature / design change, old
642     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
643     as deprecated but are still there and should provide full behavior
644     backward compatibility).
645     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
646     unsafe and caused compilation error with clang 2.x).
647 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
648 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
649     sampler from the command line by providing LSCP aware features.
650 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
651     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
652     - VirtualMidiDevice: Added support for pitch bend.
653 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
654     polyphonic key pressure events (so far polyphonic pressure was not
655     supported at all, and channel pressure was rerouted as CC128 but not
656     used so far).
657 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
658     code is shared by all sampler engine implemementations, however only the
659     gig file format currently provides support for storing instrument scripts
660     (as LinuxSampler extension to the original GigaStudio 4 format).
661 iliev 2012
662 persson 2043 * Gigasampler format engine:
663     - implemented the "round robin keyboard" dimension
664     - fixed round robin and random dimensions for cases when number of
665     dimension zones is not a power of two
666     - made round robin use a counter for each region instead of each
667     key
668 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
669     - bugfix: filter keyboard tracking was broken
670     - filter performance fix (an unnecessary copy was made of the
671     filter parameters in each sub fragment)
672     - handle special case when pan parameter in gig file has max or
673     min value
674 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
675     doesn't sound naturally with a drumkit
676 persson 2408 - fixed EG1 modulation when attack or release is zero
677 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
678 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
679     conditions (see also previous commit on libgig).
680 persson 2673 - fixed behaviour of filter LFO
681 persson 2043
682 schoenebeck 2047 * SFZ format engine:

696 persson 2063 - added support for off_mode=normal
697 persson 2072 - added support for random, seq_position, seq_length and volume
698     - added v1 LFO opcodes to parser (no support in engine yet)
699 persson 2082 - added support for amp_veltrack and amp_velcurve_N
700     - fine-tuned the default velocity curve
701 persson 2086 - added support for transpose
702     - fixed crash when using sw_down/up
703     - improved logic for sw_lokey/hikey/up/down/last
704     - added more v1 aliases to parser
705 persson 2091 - reduced memory usage for sfz data
706 persson 2101 - RT-safeness: avoid malloc in audio thread
707     - fixed a bug that could cause voice stealing to fail
708 persson 2106 - optimized sample lookup
709 persson 2114 - improved support for exclusive groups (group, off_by and
710     off_mode)
711 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
712     - added support for loop_mode=one_shot
713 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs
714     - added support for Ogg Vorbis sample files
715 persson 2167 - use loop markers from sample file if loop_start and loop_end are
716     not set in sfz file
717 persson 2175 - implemeted filters. Filter types: lowpass, bandpass, bandreject
718     and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
719     cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
720     cutoff_cc, cutoff_chanaft.
721     - bugfix: zero ampeg_sustain didn't work
722 persson 2176 - added support for velocity effect on amplifier envelope time
723     (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

1051     refresh) could cause instruments to be unloaded
1052 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
1053     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1054 persson 2185 - Mac OS X: fixed hanging threads

1058     after MIDI/audio device creation failure
1059 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1061     took the full preloading time and on 1st program change the respective
1062     instrument was completely reloaded again.
1063 persson 2277 - fixed handling of rapid bank select and program change messages
1064     sent to the same sampler channel (patch from the Open Octave

1083 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
1084     crashes and noise on such transitions).
1085 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1086     (fixes #208)
1087 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
1088     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1089     practically irrelevant, however it caused problems with the new LSCP
1090     shell's auto completion feature).
1091 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
1092     after each other (fixes #231).

1120 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
1121     plugin DLL on Windows systems failed
1122 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1123     - optimized the SynchronizedConfig class so it doesn't wait
1124     unnecessarily long after an update
1125 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off

1142 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
1143     be switched on by command line option "--stacktrace" (the automatic
1144     stacktrace mechanism seems to be broken on most systems at the moment)
1145 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1146     a pointer to the launched InstrumentEditor object
1147 schoenebeck 1876 - added optional 3rd party user data parameter for following
1148     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

1171 persson 1888 - applied old fixes to the ASIO driver that were included in the
1172     previous binary release but accidentally never committed to CVS
1173     (fixes #117)

1182     stereo
1183 persson 1922 - added channel routing, fxsends and midi maps to the settings
1184     stored in the plugin state

1190 schoenebeck 1599
1191 persson 1651 * MIDI driver:
1192     - added JACK MIDI driver
1193 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

1195     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1196 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1197 persson 1887 CoreMidi or AU
1198 persson 1889 - fixed mingw-w64 compilation error in MME driver
1199 persson 1924 - made program change handling in MIDI thread real-time safe by

1201 persson 1951 - fixed minor memory leak in ALSA driver
1202 persson 1651
1203 schoenebeck 1604 * instruments database:

1205     to the instruments database
1206 iliev 1727 - added support for handling lost files in the instruments database
1207 iliev 1781 - Implemented option for adding instruments in separate directories
1208     in the instruments database

1210 persson 1908 - work-around for missing fnmatch function on Windows to make
1211     instrument database compilable
1212 schoenebeck 1930 - added instrument database support on Windows
1213     works with both standalone mode and VST plugin.
1214     the instruments DB file is located in
1215     %USERPROFILE%\.linuxsampler\instruments.db which allows different
1216     databases for each windows user
1217     if no DB is present it automatically creates the .linuxsampler subdir
1218     and then creates an empty DB
1219 persson 1943 - fixed recursive import, which was broken on Windows
1220 iliev 1603
1221 persson 1644 * Gigasampler format engine:
1222     - fixed a memory leak that could happen when a channel was deleted
1223     while notes were playing
1224 persson 1646 - made it possible to load an instrument even if the audio thread
1225     isn't running
1226 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
1227     enough for piano gigs with pedal noise samples

1229     respective FX send MIDI controller was used
1230 schoenebeck 1724 - added support for GM global device volume SysEx message
1231 schoenebeck 1762 (can be selected at compile time to either apply globally to the
1232     whole sampler [default] or only to the sampler channels that are
1233     connected to the respective MIDI input port the SysEx message arrived
1234     on)
1235 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
1236     sometimes wrongly killed in the same buffer, causing no sound to
1237     be played
1238 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
1239     which is usally used to switch a part between chromatic sounds and
1240     drumkit sounds (as opposed to their common default setting of MIDI
1241     part 10 being a drumkit part and all other ones chromatic parts), in
1242     LS however one can switch between the first 16 MIDI instrument maps
1243     defined for the sampler
1244 persson 1764 - made it possible to create multiple sample channels even if the
1245     audio thread isn't running
1246 persson 1844 - fixed crash when removing channel with active voices (#116)
1247 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
1248     un-cache the respective sample if it's really not used by any
1249     sampler engine anymore
1250     - re-cache samples in case they were changed by an instrument editor,
1251     e.g. when a sample was added while playing (#82)
1252 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
1253     same time stamp as the voice's note-on event and occured both in the
1254     same audio fragment cycle (fixes bug #112)
1255 persson 1858 - added support for the "fine tune" and "pitch bend range"
1256     instrument-level gig parameters
1257     - fixed minor artifacts in pitch bend handling
1258 schoenebeck 1860 - added support for GS Reset SysEx message
1259 persson 1862 - allow gig files to use unlimited downward pitch shifting
1260     - added a limit check for upward pitch shifting
1261 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
1262     note was silent
1263 persson 1923 - fixed crash happening when a pitch bend event arrived at the
1264     same time a new instrument was loading
1265 persson 1644
1266 schoenebeck 1687 * LSCP server:
1267     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1268     react on MIDI data arriving on certain sampler channels (so far only
1269     Note-On and Note-Off events are sent via this LSCP event)
1270 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1271     react on MIDI data arriving on certain MIDI input devices (so far only
1272     Note-On and Note-Off events are sent via this LSCP event)
1273 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1274     SET DB_INSTRUMENT FILE_PATH
1275 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1276     frontends to send MIDI messages to specific sampler channel
1277     - added two additional fields to GET FILE INSTRUMENT INFO command -
1278     KEY_BINDINGS and KEYSWITCH_BINDINGS
1279 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1280     was incorrect
1281 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
1282 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
1283     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1284     be triggered respectively
1285     - added new LSCP command "SET STREAMS" to globally alter the maximum
1286     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1287     which will be triggered respectively
1288 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1289     a gigedit file dialog is opened)
1290 iliev 1848 - close all connections when LSCPServer is deleted
1291 iliev 1882 - hard close of all sockets on exit
1292 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1293     driver
1294 schoenebeck 1687

1296     - fixed a crash which occurs when removing a sampler channel waiting
1297     to start instrument loading after another channel
1298 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
1299     instrument loading in progress (bug #113)
1300 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
1301     instrument with PERSISTENT load mode
1302 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
1303     - fixed memory leaks when issuing the following LSCP commands:
1304     GET AUDIO_OUTPUT_DRIVER INFO
1305     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1306     GET MIDI_INPUT_DRIVER INFO
1307     GET MIDI_INPUT_DRIVER_PARAMETER INFO
1308     - fixed possible compilation error when sqlite is not present
1309 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1310 iliev 1847 - fixed crash when changing the audio output device of a sampler
1311     channel with loaded instrument and start playing notes
1312 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1313 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
1314     PowerPC, which probably could cause crashes on that platform
1315 persson 1889 - fixed a memory management error which could cause a crash when a
1316     plugin was unloaded
1317 persson 1896 - bugfix: two private structs had the same name, which could cause
1318     problems if the linker chose the wrong constructor
1319 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
1320     Windows
1321 iliev 1761
1322    
1323 schoenebeck 1560 Version 0.5.1 (6 December 2007)
1324 schoenebeck 1454
1325     * packaging changes:
1326     - added autoconf checks for pthread library
1327     - added autoconf check for pthread bug found on certain NPTL-enabled
1328     glibc versions (see Gentoo bug report #194076)
1329 senoner 1502 - added autoconf checks for MS Windows
1330 schoenebeck 1454
1331 persson 1455 * general changes:
1332     - bugfix: the thread used by an editor plugin didn't die when the
1333     editor closed
1334 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1335     out all the space. operator--() did not apply size_mask after
1336     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1337     order to avoid problems with the _NonVolatileReader functions.
1338     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1339     GetWriteSpace(). Since this function is currently only used in
1340     the stream's qsort() compare function, it didn't trigger any
1341     bugs.
1342     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1343     24bit mode too. Faster method to read 24bit words on little
1344     endian machines (x86): replaced 3 byte reads + shifts with a 1
1345     unaligned 32bit read and shift
1346     - experimental support for MS Windows (MIDI input via MME, AUDIO
1347     output via ASIO)
1348     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1349 iliev 1541 - support for monitoring the total number of active disk streams
1350     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1351     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1352 persson 1455
1353 senoner 1500 * AUDIO driver:
1354 persson 1534 - added Windows ASIO low latency audio driver
1355 senoner 1500
1356 senoner 1485 * MIDI driver:
1357 schoenebeck 1495 - added MME Windows MIDI driver
1358 senoner 1485
1359 schoenebeck 1471 * LSCP server:
1360     - added support for Windows style path / filenames, however with
1361     forward slash path separators instead of backslash
1362     (i.e. "C:/foo/bar.gig")
1363 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1364     apostrophes as well
1365 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1366     "LIST FILE INSTRUMENTS <file>" and
1367     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1368     about an arbitrary instrument file on the system where the sampler is
1369     running on
1370 schoenebeck 1471
1371 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1372 schoenebeck 947
1373 schoenebeck 1065 * packaging changes:
1374 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1375     API header files anymore
1376 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1377     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1378 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1379     capable to execute our autoconf environment, thus no need anymore
1380     to maintain the compile time configuration file (osx/version.h) for
1381     OSX manually (patch by Toshi Nagata)
1382 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1383     parameters
1384 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1385     C++ API header files, all implementation internal global definitions
1386     are now in global_private.h
1387     - atomic.h is not exposed to the C++ API anymore
1388     - no need to include config.h anymore for using LS's API header files
1389     - fixed warnings in API doc generation
1390 schoenebeck 1065
1391 schoenebeck 947 * general changes:
1392     - replaced the old, confusing MIDI program change mechanism by a
1393     flexible MIDI instrument mapper which allows to map arbitrary
1394 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1395 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1396     loaded on the respective channel when such MIDI program change
1397     messages arrive, beside that, each entry allows to define a life-time
1398     strategy for the instrument, so the user can define whether the
1399     instrument should i.e. be permanently loaded (to be able to switch
1400     quickly among sounds) or i.e. loaded just on demand when the
1401     respective program change arrives (to safe RAM space), as well as a
1402     global volume factor for each entry, so the user can adjust the volume
1403     dynamic of his mapped instrument collection without having to modify
1404 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1405     MIDI instrument maps and assign each sampler channel individually
1406     a certain map, so that i.e. separation of normal instruments and
1407     drumkits is possible
1408 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1409     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1410 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1411     due to a constant size RingBuffer FIFO which is now replaced by a
1412     dynamic (unlimited) size std::list FIFO
1413 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1414     output channels for being processed by external effect processors
1415     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1416     controllers
1417 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1418 iliev 1130 - Implemented new, improved notification system
1419 schoenebeck 1149 - fixed compilation errors regarding OSX
1420     (patch by Toshi Nagata)
1421 iliev 1161 - implemented instruments database
1422 iliev 1345 - added support for escape sequences to the instruments database
1423 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1424     within the sampler's process (by using instrument editor plugins),
1425     you'll notice the new "Registered instrument editors:" message on
1426 schoenebeck 1407 startup, added a new LSCP command:
1427     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1428 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1429     given sampler channel, the plugin path can be overridden at compile
1430     time with ./configure --enable-plugin-dir=/some/dir
1431 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1432     in the sampler's process to safely edit instruments while playing
1433     without a crash (hopefully) by either suspending single regions
1434     wherever possible or if unavoidable whole engine(s)
1435 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1436     policy and priority on thread level, set a minimum stack size for
1437     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1438     threads simply inherited properties of starting thread instead of
1439     setting their own policy and priority
1440 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1441     main process did not wait for the stack trace process to finish
1442     its output
1443 persson 1248 - fixed some minor memory leaks
1444 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1445     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1446 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1447     register, to avoid relocations in the text segment at runtime)
1448 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1449 schoenebeck 947
1450     * MIDI driver:
1451     - dispatch bank select (MSB and LSB) messages
1452    
1453 schoenebeck 1049 * audio driver:
1454     - the ALSA audio output driver parameters now reflect the correct
1455     parameter value ranges for the respective selected sound card
1456     (patch by Till Wimmer, a bit fixed and extended)
1457    
1458 persson 951 * Gigasampler format engine:
1459     - if a filter is used and EG2 finishes before EG1, let the voice
1460     die when EG2 has finished (this fixes a problem with clicks and
1461     voice starvation for some gigs)
1462 persson 1038 - playback is no longer disabled during instrument loading
1463     - all notes playing on a channel that changes its instrument keep
1464     playing with the old instrument until they get a note off
1465     command
1466 persson 1039 - EG fix: a release value of zero could cause noises or crash
1467 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1468 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1469     above max sustain level, which means that there is a decay phase
1470     even if sustain is 100%
1471 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1472     noises or crashes
1473 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1474 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1475     supplied to the configure script (fixes #46)
1476 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1477     instead of a fix value
1478 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1479     127 (solo mode) only kill voices if the respective mode really
1480     changed
1481 persson 951
1482 schoenebeck 1244 * LSCP server:
1483     - fixed compile time error for old Bison versions
1484     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1485 schoenebeck 1245 - parser now supports extended ASCII character set
1486     (up to ASCII code 255, i.e. includes now umlauts and accents)
1487     - filename arguments in LSCP commands now allow to use escape
1488     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1489     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1490     code value like \xf2) (fixes bug #24)
1491 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1492     least one of their text-based parameters (i.e. name, description):
1493     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1494     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1495     "SET DB_INSTRUMENT_DIRECTORY NAME",
1496     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1497     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1498     "FIND DB_INSTRUMENT_DIRECTORIES"
1499 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1500     occured, the unexpected character and the actually expected, possible
1501     character(s), the latter only if less than 5 possibilities)
1502 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1503     settings
1504 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1505     of strings were treated as being one string containing commas
1506     (fixes #57)
1507 schoenebeck 1244
1508 iliev 959 * Bug fixes:
1509     - fixed crash occurring on certain LSCP scripts (Bug 39)
1510 persson 1038 - another thread safety fix for lscp "load engine" and "set
1511     channel audio output device"
1512 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1513     on a sampler channel with connected MIDI device
1514 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1515     device connected to a sampler channel to number less then or equal
1516     to the index of the port to which the sampler channel is connected.
1517 iliev 1296 - The previous bindings were not been disconnected when altering
1518     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1519     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1520 iliev 1297 - The active stream/voice count statistic was incorrect.
1521 iliev 1298 - notification events were not been sent for some sampler
1522     channel changes
1523 iliev 1305 - added default min and max values to restrict the number of allowed
1524     audio output channels and MIDI input ports
1525 iliev 1306 - the connection to the PCM interface is now closed when destroying
1526     an audio output device
1527 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1528 iliev 959
1529 schoenebeck 1221 * test cases:
1530     - updated and fixed (haven't been touched in a while)
1531    
1532 schoenebeck 937 Version 0.4.0 (24 November 2006)
1533 persson 696
1534 schoenebeck 697 * packaging changes:
1535 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1536     to post-(un)install steps; added devel package for liblinuxsampler;
1537     to linuxsampler.spec (RPM)
1538 schoenebeck 697 - install necessary development header files for allowing 3rd party
1539     applications to link against liblinuxsampler
1540     - liblinuxsampler's API documentation can be generated with 'make docs'
1541     (Doxygen required)
1542 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1543     implementation (currently either an integer math solution or a
1544     di-harmonic approximation), automatic detection can be overriden
1545     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1546     configure script argument though (mandatory for cross-compilation)
1547 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1548     provided some on his own (as CXXFLAGS)
1549 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1550     messages
1551 schoenebeck 852 - added compile time options to allow disabling the various audio and
1552     MIDI drivers
1553 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1554     (patch by Ebrahim Mayat)
1555 schoenebeck 697
1556 persson 696 * Gigasampler format engine:
1557 schoenebeck 738 - extensive synthesis optimization
1558     (reimplementation of EGs and LFO(s), removed synthesis parameter
1559     prerendering and the synthesis parameter matrix in general, splitting
1560     each audio fragment into subfragments now where each subfragment uses
1561 persson 830 constant pitch and filter coefficients. The volume coefficient is
1562     linearly interpolated inside a subfragment, unless
1563     --disable-interpolate-volume is set.)
1564 persson 696 - fine tuning of the EG modulation parameters
1565 persson 729 - improved filter cutoff calculation by adding support for the
1566     following gig parameters: Cutoff freq (used when no cutoff
1567     controller is defined), Control invert, Minimum cutoff, Velocity
1568 persson 791 curve and Velocity range. The keyboard tracking now scales
1569     cutoff frequency instead of resonance.
1570 persson 877 - added support for gig parameter Resonance.
1571 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1572 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1573     which can be overridden with --enable-global-attenuation
1574 persson 783 - EG fixes: made the length of "attack hold" stage more
1575     accurate. Release stage can now start before attack stage
1576 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1577     time now has a minimal value to prevent clicks.
1578 persson 799 - fixed pitch changes larger than one octave
1579 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1580     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1581     all modes can be altered via standard GM messages, that is CC5 for
1582     altering portamento time, CC65 for enabling / disabling portamento
1583     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1584 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1585     parameter) and crossfade
1586 persson 831 - added support for the "attenuation controller threshold" gig
1587     parameter
1588 persson 832 - added smoothing of volume changes caused by control change
1589     messages
1590 persson 865 - sample loop parameters are now taken from the DimensionRegion
1591     instead of the wave chunk
1592     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1593     not equal to a power of two
1594 persson 877 - reimplementation of the filter algorithm. The new filter is more
1595     accurate and supports all gig filter types, including bandreject
1596     and lowpass turbo.
1597 persson 903 - real support for 24 bit samples - samples are not truncated to
1598     16 bits anymore
1599     - support for aftertouch (channel pressure, not polyphonic
1600     aftertouch)
1601 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1602     amplifying from 0)
1603 persson 696
1604 schoenebeck 711 * LSCP server:
1605     - fixed application exit on broken pipe error (fixes bug #20)
1606 iliev 793 - fixed the notification messages delay due to lack of
1607     network activity (fixes bug #26)
1608 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1609     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1610 schoenebeck 711
1611 schoenebeck 838 * audio driver:
1612     - added aRts audio output driver (by no means RT safe)
1613    
1614 schoenebeck 775 * MIDI driver:
1615     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1616     messages several times instead of once
1617 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1618     for events (i.e. for offline rendering based MIDI drivers)
1619 persson 922 - added checks for bad MIDI data
1620 schoenebeck 775
1621 schoenebeck 900 * linuxsampler application:
1622     - show available sampler engine types on startup
1623    
1624 schoenebeck 705 * general changes:
1625     - support for muting sampler channels and solo mode of the same, two new
1626     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1627     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1628     introduced for this, the behavior is the same like on a mixer console
1629 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1630     --enable-process-muted-channels which can be used to enable the
1631     processing of muted channels.
1632 iliev 777 - support for sostenuto pedal
1633 iliev 779 - support for monitoring the total number of active voices
1634 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1635     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1636 persson 835 - fixed some memory management errors
1637 persson 841 - fixed some concurrency problems that could lead to crashes when
1638     LSCP commands were executed
1639 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1640     sampler channel (fixes bug #36)
1641 schoenebeck 705
1642 schoenebeck 692 Version 0.3.3 (15 July 2005)
1643 schoenebeck 686
1644     * packaging changes:
1645     - fixed compilation with gcc 4.0
1646    
1647 schoenebeck 687 * Gigasampler format engine:
1648     - LFO preprocessing was performed even though the respective LFO was
1649     disabled by the instrument patch (minor efficiency fix)
1650 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1651     for volume ramp downs in the same fragment (needed for current voice
1652     stealing implementation) then simply inform the user with a warning
1653     about possible click sounds and reduce the volume ramp down
1654     appropriately instead of cancelling the audio device connection
1655 schoenebeck 687
1656 schoenebeck 677 Version 0.3.2 (24 June 2005)
1657 schoenebeck 609
1658     * packaging changes:
1659     - updated autotools build files to compile on OS X
1660     (conditional compilation of CoreMIDI and MidiShare drivers)
1661 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1662     './configure --disable-asm' (definitely not recommended)
1663 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1664     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1665     (due to 'dist-bzip2' automake option)
1666 schoenebeck 649
1667     * Gigasampler format engine:
1668     - support for the gig parameters for "release velocity response" curves
1669     - fine tuning of the EGADSR envelope
1670     - volume of release triggered samples now depends on note-on velocity,
1671     note length and gig parameter "release trigger decay" instead of
1672     note-off velocity.
1673 schoenebeck 663 - revised voice stealing
1674     (fixes crash and endless loop caused by voice stealing)
1675 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1676 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1677     instead of when the respective voice is actually launched
1678     (fixes undefined behavior if stolen voices belonged to a key group -
1679     this case was followed by a "killed voice survived" error message)
1680 schoenebeck 669 - fixed minor issue with null/silence samples
1681     (those stole voices even though they don't need a voice at all which
1682     resulted in "voice stealing didn't work out" messages)
1683 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1684     instrument or audio output device change
1685 schoenebeck 654
1686 schoenebeck 620 * LSCP server:
1687 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1688 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1689 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1690 schoenebeck 609
1691 schoenebeck 668 * linuxsampler application:
1692     - added command line parameters --lscp-addr and --lscp-port to override
1693     default IP address and port of LSCP server
1694    
1695 schoenebeck 579 Version 0.3.1 (24 May 2005)
1696    
1697     * initial release
