1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          expected floating point tolerances into account.
13        - Added public API C++ class "LFO", which is a cluster class encapsulating
14          all the sampler's LFO implementations to be used by 3rd party applications
15          (e.g. by Gigedit).
16        - Added int math square LFO implementation.
17        - Added int math saw LFO implementation.
18        - Added numeric complex nr sine LFO implementation.
19        - Marked class LFOTriangleDiHarmonic as deprecated
20          (will be removed in future).
21        - Added LFOAll.h which includes all LFO implementation's header files.
22        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25          SquareLFO -> LFOSquarePulse and separated the latter to its own header
26          file).
27        - Renamed type LFOSigned -> LFOTriangleSigned.
28        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29        - Using now cubic interpolation as resampling algorithm by default; and
30          linear interpolation is deprecated now.
31        - Event:Init(): memset() entire Event::Param union to zero instead of trying
32          to do that for its individual members; the latter became error prone due
33          to the union's growing complexity meanwhile.
34        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36          methods and marked the old ones as deprecated; and likewise added new
37          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38          methods and marked those old ones deprecated as well.
39        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41    
42      * Real-time instrument scripts:
43        - Added method ScriptVM::setExitResultEnabled() which allows to
44          explicitly enable the built-in exit() function to optionally accept
45          one function argument; the value of the passed exit() function
46          argument will then become available by calling
47          VMExecContext::exitResult() after script execution.
48        - 64 bit support for NKSP integer scripts variables (declare $foo).
49        - Variable names, function names and preprocessor condition names must start
50          with a regular character (a-z or A-Z); starting them with a digit or
51          underscore is not allowed.
52        - NKSP parser fix: equal comparison operator "=" and not equal comparison
53          operator "#" must only accept integer operands.
54        - NKSP language: Implemented support for standard units like Hertz, seconds,
55          Bel including support for metric unit prefixes; so one can now e.g.
56          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
57          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
58          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
59        - NKSP language: Introduced "final" operator "!" which is specifically
60          intended for synthesis parameter values to denote that the synthesis
61          parameter value is intended to be the "final" value for that synthesis
62          parameter that should explicitly be used by the engine and thus causing
63          the sampler engine to ignore all other modulation sources for the same
64          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
65          variable or formula with this new "!" operator the expression is marked as
66          being "final".
67        - NKSP script editor API: Added support for detecting standard unit tokens
68          and their potential metric prefix token.
69        - NKSP language: Added support for NKSP real number literals and
70          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
71        - NKSP language: Added support for NKSP real number (floating point) script
72          variables (declare ~foo).
73        - NKSP language: Added support for NKSP real number (floating point) array
74          script variables (declare ?foo[]).
75        - Built-in script function "message()" accepts now real number argument as
76          well.
77        - Added built-in script function "real_to_int()" and its short hand form
78          "int()" for casting from real number to integer in NKSP scripts.
79        - Added built-in script function "int_to_real()" and its short hand form
80          "real()" for casting from integer to real number in NKSP scripts.
81        - Allow built-in exit() function to potentially accept real number type
82          argument as well.
83        - Built-in script functions may have a different return type depending on
84          the arguments passed to the function.
85        - Built-in script function "abs()" optionally accepts and returns real
86          number.
87        - Built-in script functions "min()" and "max()" optionally accept real
88          number arguments and return real number as result in that case.
89        - NKSP VM API: Allow units and 'final'ness to be returned as result from
90          built-in functions (added methods VMFunction::returnUnitType() and
91          VMFunction::returnsFinal() for that purpose which must be implemented by
92          built-in function implementations).
93        - NKSP language: Allow metric unit prefixes of numeric scalar and array
94          variables to be changed freely at runtime (unlike unit types like Hz etc.
95          which are still sticky, parse-time features of variables which cannot be
96          changed at runtime for the intentional sake of determinism).
97        - NKSP language: 'final' values are prohibited for array variables for now
98          (attempt causes a parsers error).
99        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
100          conditions of runtime control structures like if(), while(), select()
101          (attempt causes a parser error).
102        - NKSP VM API: Allow built-in functions to perform their own, individual
103          parse time checks of arguments going to be passed to the function at
104          runtime (added method VMFunction::checkArgs() for that purpose).
105        - NKSP language: raise parser warning if only one operand of binary
106          operators (like logical 'or' comparison) contain a 'final' value (because
107          it would always yield in a 'final' result in such cases).
108        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
109          different metric unit prefixes, which will behave as expected (e.g.
110          result of expression '1000us < 2ms' is true).
111        - NKSP language: Allow adding values with different metric unit prefixes
112          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
113        - NKSP language: Allow subtracting values with different metric unit
114          prefixes (e.g. result of expression '1ms - 20us' is '980us').
115        - NKSP language: Allow multiplying with any metric unit prefixes
116          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
117          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
118          we don't have any considerable practical use for a term like '4s^2'
119          (hence any attempt multiplying two unit types still causes parser error).
120        - NKSP language: Allow dividing by any metric unit prefixes and allow
121          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
122          yields in unit free result '8'). So this is now a way to cast units away
123          e.g. for passing the result to other expressions, certain function calls
124          or variables which are not accepting any units (or that specific unit).
125        - NKSP language: integer arrays and real number arrays can now be converted
126          to strings (e.g. for dumping their content with message() calls for
127          script debugging purposes).
128        - NKSP language: expressions and variables with units are now correctly
129          casted to strings (e.g. with message() calls).
130        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
131          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
132          floating point tolerances into account.
133        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
134          VMScalarNumberExpr::evalCastReal().
135        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
136          'VMIntArrayExpr' and 'VMRealArrayExpr'.
137        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
138          unitFactor() (runtime) methods.
139        - Built-in function "exit()" supports now returning units and 'final'ness
140          for test cases.
141        - The following built-in functions support now units as well: "abs()",
142          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
143          "real_to_int()", "int()", "int_to_real()" and "real()".
144        - Built-in functions "array_equal()", "search()" and "sort()" support now
145          real number arrays (correctly) as well.
146        - Added individual parse time checks of arguments to be passed to built-in
147          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
148          "array_equal()" and "search()" specific for their individual purposes.
149        - NKSP VM refactoring: Renamed all methods, functions and classes matching
150          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
151          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
152          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
153          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
154          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
155          isScalarNumber() -> isNumber()).
156        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
157          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
158          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
159          as convenient methods for automatically converting values to expected
160          metric value basis.
161        - Built-in function "wait()" accepts now both integers and real numbers as
162          argument.
163        - NKSP VM API cleanup: Get rid of legacy method
164          VMFunction::argType(vmint iArg) which was already superseded by its new
165          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
166        - NKSP parser: if wrong argument type was passed to a built-in function and
167          that built-in function accepts more than one data type for the argument,
168          then show all supported data types as parser error message.
169        - Built-in function "play_note()" accepts now real numbers and seconds as
170          unit type as well for its 3rd and 4th function arguments.
171        - The following built-in functions accept now real numbers as well for their
172          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
173          "change_attack()", "change_decay()", "change_release()",
174          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
175          "change_cutoff_sustain()", "change_cutoff_release()",
176          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
178          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
179        - Fixed built-in function "change_play_pos()" not having accepted metric
180          prefixes at all.
181        - Fixed the following built-in functions having misinterpreted values given
182          with unit type (for their 2nd argument) as if they were relative values
183          (that is as if they were passed without a unit type): "change_attack()",
184          "change_decay()", "change_release()", "change_cutoff_attack()",
185          "change_cutoff_decay()", "change_cutoff_release()".
186        - Fixed the following built-in functions having applied completely wrong
187          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
188          respective EGs being their modulation sink assume uint data type with
189          value range 0..1000 instead of 0.0..1.0.
190        - Added individual parse-time checks of function arguments for the following
191          built-in functions: "play_note()", "note_off()", "set_event_mark()",
192          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
193          "change_decay()", "change_release()", "change_cutoff_attack()",
194          "change_cutoff_decay()", "change_cutoff_release()",
195          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
196          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
197          "change_pan_time()".
198        - Don't abort function call if unit type was used and at the same time
199          'final' operator was omitted for the primary value argument of the
200          following built-in functions: "change_cutoff()", "change_attack()",
201          "change_decay()", "change_release()", "change_cutoff_attack()",
202          "change_cutoff_decay()", "change_cutoff_release()",
203          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
204          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
205          "change_pan_time()", instead imply 'final'ness at runtime and raise an
206          appropriate parser warning at parse time.
207        - Added built-in real number functions "round()", "ceil()", "floor()",
208          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
209          "cos()", "tan()", "asin()", "acos()", "atan()".
210        - Added built-in script real number constant "~NI_MATH_PI".
211        - Added built-in script real number constant "~NI_MATH_E".
212        - NKSP language: Allow unary '+' operator.
213        - Added built-in script functions "msb()" and "lsb()".
214        - NKSP language: Added support for RPN event handler
215          ("on rpn ... end on" in instrument scripts).
216        - NKSP language: Added support for NRPN event handler
217          ("on nrpn ... end on" in instrument scripts).
218        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
219          may be read from the new RPN/NRPN script handlers to get the (N)RPN
220          parameter that had been changed and its new value.
221        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
222          which are identifying the new (N)RPN handlers as such at script runtime.
223        - Implemented built-in script function "set_rpn()".
224        - Implemented built-in script function "set_nrpn()".
225    
226      * test cases:
227        - Fixed compiler errors in test cases.
228        - Updated README for how to compile & run test cases.
229        - Updated test case
230          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
231          expected behaviour of the Mutex class implementation (recursive
232          mutex type).
233        - Added test cases for NKSP core language aspects and core built-in
234          functions.
235        - Fixed thread tests segfaulting on Linux.
236        - NKSP: Added real number test cases for built-in functions exit(),
237          int_to_real(), real(), real_to_int() and int(), as well as for the
238          plus, minus and negate language operators.
239        - Added massive amount of NKSP test cases for standard measuring units and
240          'final' operator usage cases.
241        - Added NKSP test cases for (floating point tolerance aware) real number
242          equalness / unequalness comparison.
243        - Added NKSP int array and real array tests for value assignment and
244          initialization of arrays.
245        - Added NKSP test cases for built-in functions "round()", "ceil()",
246          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
247          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
248        - Added NKSP test cases for unary '+' operator.
249    
250      * GigaStudio/Gigasampler format engine:
251        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
252          behaviour for start_level_mid.
253        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
254          level (see discussion "GigaStudio LFO compatibility" on mailing list
255          from 2019-09-26 for details).
256        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
257          see discussion "GigaStudio LFO compatibility" on mailing list from
258          2019-09-26 for details).
259        - Format extension: Added support for different LFO wave forms (currently
260          either sine [default], triangle, saw or square).
261        - Format extension: Added support for LFO phase displacement (0°..360°).
262        - Format extension: Added support for flipping LFO polarity on LFO 3
263          (in the original gig format this was only available for LFO 1 and LFO 2).
264        - Format extension: Support for additional filter types:
265          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
266          bandreject 2-pole.
267    
268      * SFZ format engine:
269        - Fixed support for regions with loccN/hiccN conditions on more than one
270          MIDI controller.
271    
272      * Benchmarks:
273        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
274          algorithm (since result of 2nd run was not accumulated).
275        - Added benchmark for saw wave (benchmarks/saw.cpp).
276        - Added benchmark for sine wave (benchmarks/sine.cpp).
277        - Added benchmark for square wave (benchmarks/square.cpp).
278        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
279          which are large enough on modern systems.
280    
281    Version 2.1.1 (27 Jul 2019)
282    
283      * Real-time instrument scripts:
284        - Fixed behavior of built-in NKSP functions change_sustain(),
285          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
286          and change_cutoff_release().
287    
288      * general changes:
289        - Only play release trigger samples on sustain pedal up if this behaviour
290          was explicitly requested by the instrument (otherwise only on note-off).
291        - Fixed compiler warnings.
292        - Fixed compilation error when cross-compiling to Mac.
293        - FX Sends: Provide more useful error messages on routing problems
294          (see bug #169).
295        - LSCP doc: Be more clear describing the two distinct approaches
296          of using external vs. internal effects (see bug #169).
297        - "optional" class: Fixed comparison operators.
298    
299      * Gigasampler/GigaStudio format engine:
300        - Format extension: If requested by instrument then don't play release
301          trigger sample on note-off events.
302    
303      * SFZ format engine:
304        - Fixed memory leak when releasing samples
305          (fixes bug #307, patch by Jacek Roszkowski)
306        - Fixed potential crash when a sample is shared by more than one region
307          (fixes bug #308, patch by Jacek Roszkowski).
308        - Opcode 'sample': Added support for built-in sample '*silence'
309          (fixes bug #310, patch by Jacek Roszkowski).
310    
311    Version 2.1.0 (25 Nov 2017)
312    
313      * SFZ format engine:
314        - added support for <global>, <master> and #define (patch by Alby M)
315        - Removed code duplication in SFZ file loading code.
316        - Added support for sfz extension opcode 'script' which may be used to
317          load real-time instrument script file (NKSP script language).
318        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
319        - Fixed unintended volume fade-in of voices under certain conditions.
320        - sfz parser: allow missing space between header and opcode
321    
322      * Gigasampler/GigaStudio format engine:
323        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
324          cutoff settings.
325        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
326          all if an up-pitch of more than 40 semi tones was requested (I don't
327          think there is any stock gig sound that requires this behavior to
328          resemble its original sound).
329        - Added support for controlling whether the individual EGADSR stages may
330          be aborted (as LinuxSampler extension to the original GigaStudio 4
331          format).
332    
333      * general changes:
334        - fixed printf type errors (mostly in debug messages)
335        - use unique_ptr instead of auto_ptr when building with C++11
336        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
337          allowing to sort data efficiently in real-time safe manner.
338        - RTList class: added methods for moving/inserting elements to arbitrary
339          position within a list.
340        - RTList class: added method fromPtr() for creating an Iterator object from
341          a raw element pointer.
342        - Attempt to partly fix resetting engine channels vs. resetting engine, an
343          overall cleanup of the Reset*(), ConnectAudioDevice(),
344          DisconnectAudioDevice() API methods would still be desirable though,
345          because the current situation is still inconsistent and error prone.
346        - Active voices are now internally grouped to "Note" objects, instead of
347          being directly assigned to a keyboard key. This allows more fine graded
348          processing of voices, which is i.e. required for certain instrument
349          script features.
350        - Fix: Release trigger voices were not spawned on sustain pedal up
351          (CC #64) events.
352        - Fix: Release trigger voices can now also distinguish correctly between
353          note-off and sustain pedal up events.
354        - All engines: Increased ramp speed of volume smoother and pan smoother
355          (while slow rate of crossfade smoother is preserved) to allow quick
356          volume and pan changes by instrument scripts for instance.
357        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
358          properly and thus were ignored for certain uses.
359        - Added new C++ API method
360          VirtualMidiDevice::SendChannelPressureToSampler().
361        - windows, 32-bit: fixed potential crashes by making sure the stack in
362          sub threads is 16-byte aligned
363        - fixed numerous compiler warnings
364        - Fixed invalid (note-on) event ID being assigned to new Note objects.
365        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
366          fixes potential undefined behavior.
367        - Fixed Note object leak when triggering notes on keys which did not
368          have a valid sample mapped (fixes bug #252).
369        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
370        - linuxsampler binary fix: option --create-instruments-db ignored
371          subsequent optional argument due to glibc's implementation oddity
372          which expects a "=" sign, but no space between them.
373    
374      * packaging changes:
375        - removed unnecessary dependency to libuuid
376          (originated by libgig's usage of it)
377        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
378          auto detect whether it (sh/c)ould output its messages in color.
379        - Debian: Fixed packaging error about invalid "Source-Version"
380          substitution variable.
381        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
382        - Debian: Added build dependency to libsqlite3-dev for building
383          linuxsampler with instruments DB support.
384    
385      * Real-time instrument scripts:
386        - Implemented scheduler for delayed MIDI events and for suspended scripts.
387        - Built-in script function "wait()": implemented support for function's
388          "duration-us" argument, thus scripts using this function are now
389          correctly resumed after the requested amount of microseconds.
390        - Built-in script function "play_note()": implemented support for
391          function's "duration-us" argument, thus notes triggered with this
392          argument are now correctly released after the requested amount of
393          microseconds.
394        - Fix: script events were not cleared when engine channel was reset,
395          potentially causing undefined behavior.
396        - Fixed crash which happened when trying to reference an undeclared
397          variable.
398        - Built-in script function "play_note()": Added support for passing
399          special value -1 for "duration-us" argument, which will cause the
400          triggered note to be released once the original note was released.
401        - Instrument script classes now exported with the liblinuxsampler C++ API.
402        - Added new API method ScriptVM::syntaxHighlighting() which provides
403          a convenient syntax highlighting backend for external instrument
404          script editor applications.
405        - Added new C++ API class "ScriptVMFactory".
406        - Extended parser issues to provide not only first line and first
407          column, but also last line and last column of issue (thus marking
408          the precise span of the issue within the source code).
409        - Reload script automatically after being modified by an instrument
410          editor.
411        - NKSP language grammar correction: allow empty event handler bodies
412          like "on note end on".
413        - Implemented built-in script function "change_vol()".
414        - Implemented built-in script function "change_tune()".
415        - Implemented built-in script function "change_pan()".

417        - Implemented built-in script function "change_reso()".
418        - Implemented built-in script function "event_status()".
419        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
420          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
421          "event_status()" function.
422        - NKSP language: Added support for bitwise operators ".or.", ".and."
423          and ".not.".
424        - NKSP language scanner: Fixed IDs matching to require at least one
425          character (i.e. when matching function names or variable names).
426        - NKSP language scanner: disabled unusued rules.
427        - Fixed behavior of play_note() and note_off() functions which must
428          be distinguished engine internally from "real" MIDI note on/off
429          events in order to avoid misbehaviors like hanging notes.
430        - Implemented built-in script variable "$KSP_TIMER".
431        - Implemented built-in script variable "$NKSP_REAL_TIMER".
432        - Implemented built-in script variable "$NKSP_PERF_TIMER".
433        - Implemented built-in script variable "$ENGINE_UPTIME".
434        - Implemented built-in script function "inc()".
435        - Implemented built-in script function "dec()".
436        - NKSP language fix: division expressions were evaluated too often.
437        - NKSP language fix: string concatenation operator was right
438          associative instead of left (to right).
439        - NKSP language correction: allow empty statements in entire language
440          (i.e. "if end if").
441        - Implemented built-in script function "stop_wait()".
442        - Implemented built-in script variable "$NI_CALLBACK_ID".
443        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
444        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
445        - Added support for read-only built-in variables (respectively
446          handled by the script parser).
447        - Added built-in script constant "$NI_CB_TYPE_INIT".
448        - Added built-in script constant "$NI_CB_TYPE_NOTE".
449        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

453        - Implemented built-in script function "change_decay()".
454        - Implemented built-in script function "change_release()".
455        - Fixed all change_*() built-in script functions to apply their
456          synthesis parameter changes immediately in case the respective note
457          was triggered at the same time, instead of scheduling the parameter
458          change, especially because it would cause some parameter types's
459          changes either to be ramped (i.e. change_vol()) or other types even
460          to have not effect at all (i.e. change_attack()).
461        - Implemented built-in script function "sh_left()".
462        - Implemented built-in script function "sh_right()".
463        - Implemented built-in script function "min()".
464        - Implemented built-in script function "max()".
465        - NKSP Fix: "init" event handler was not always executed when a script
466          was loaded.
467        - NKSP built-in wait() script function: abort script execution if
468          a negative or zero wait time was passed as argument (since this is
469          a common indication of a bug either of the script or even of the
470          engine, which could lead to RT instability or even worse).
471        - ScriptVM: Implemented automatic suspension of RT safety
472          threatening scripts.
473        - Provide more user friendly error messages on syntax errors.
474        - Fixed NKSP parser warning "Not a statement" when assigning an
475          initializer list to an array variable.
476        - Implemented built-in script array variable "%ALL_EVENTS".
477        - Implemented built-in script function "in_range()".
478        - Implemented built-in script function "change_amp_lfo_depth()".
479        - Implemented built-in script function "change_amp_lfo_freq()".
480        - Implemented built-in script function "change_pitch_lfo_depth()".
481        - Implemented built-in script function "change_pitch_lfo_freq()".
482        - Implemented built-in script function "change_vol_time()".
483        - Implemented built-in script function "change_tune_time()".
484        - Implemented built-in script function "fade_in()".
485        - Implemented built-in script function "fade_out()".
486        - Fixed acceptance of wrong data type of parameters passed to built-in
487          script functions "change_vol()", "change_tune()", "change_pan()",
488          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
489          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
490          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
491        - Added built-in script function "get_event_par()" and implemented some
492          of its possible parameter selections.
493        - Added built-in script function "set_event_par()" and implemented some
494          of its possible parameter selections.
495        - Fixed a bunch of scheduler time related bugs.
496        - Fixed polyphonic variables not being reset to zero after usage.
497        - Built-in "ignore_event()" function: argument is now optional, like with
498          built-in function "ignore_controller()".
499        - Implemented built-in script function "change_velo()".
500        - Implemented built-in script function "change_note()".
501        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
502          intuitive behavior if used in combination with "change_vol_time()" or
503          "change_tune_time()" respectively: now tuning/volume changes are only
504          assigned (without delay) immediately to a new note if the respective
505          timing function has not been called before, otherwise the volume/tuning
506          changes are automatically faded (before, only the event's time stamp was
507          relevant).
508         - Implemented built-in script function "array_equal()".
509         - Implemented built-in script function "search()".
510         - Implemented built-in script function "sort()".
511         - NKSP Fix: Never suspend "init" event handlers.
512         - Implemented built-in script function "same_region()" (currently only
513           available for gig format engine).
514         - Added built-in script constant "$NKSP_LINEAR".
515         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
516         - Implemented built-in script function "change_vol_curve()".
517         - Implemented built-in script function "change_tune_curve()".
518         - built-in "play_note()" function now supports a sample playback start
519           offset with argument 3, where special value -1 means to use the regular
520           sample offset as defined by the instrument file.
521         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
522         - Built-in variable $EVENT_NOTE is now a read-only variable.
523         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
524         - built-in "play_note()" function now accepts -2 for its fourth argument
525           (note duration) which means the life time of the note shall be sticked
526           to the requested note number of argument 1.
527         - Fix: built-in "play_note()" function now returns 0 as result value if
528           -1 was passed for its fourth argument (note duration) and the respective
529           parent note is already gone.
530        - Implemented built-in script function "change_play_pos()".
531        - NKSP language: Added support for user declared const array variables.
532        - NKSP language: Raise parser warning if array variable is accessed with
533          an index that exceeds the array's size.
534        - NKSP language fix: Unknown characters were not handled correctly.
535        - NKSP language: Added support for "synchronized .. end synchronized"
536          code blocks.
537        - Implemented built-in script function "abort()" which allows to abort
538          another script handler by passing its callback ID.
539        - Fixed potential memory access bug and potential undefined behavior of
540          "init" event handlers.
541        - Print a time stamp along to each call of built-in function "message()".
542        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
543          to retrieve all code blocks filtered out by the preprocessor.
544        - Added built-in script function "fork()".
545        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
546        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
547        - Fixed potential crash when accessing dynamic built-in array variables.
548        - Added built-in script function "callback_status()".
549        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
550        - Added built-in constant $CALLBACK_STATUS_QUEUE.
551        - Added built-in constant $CALLBACK_STATUS_RUNNING.
552        - Removed max. value limitation of built-in functions "change_attack()",
553          "change_decay()" and "change_release()" to i.e. allow passing 2000000
554          for doubling the respective time.
555        - NKSP script editor syntax highlighting API: Fixed app termination due
556          to a lexer start condition stack underrun.
557        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
558          USE_CODE_IF_NOT() preprocessor statements.
559        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
560          can be set to disable all subsequent built-in "message()" function calls
561          on preprocessor level.
562        - Implemented built-in script function "change_sustain()".
563        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
564          to avoid the editor app to crash on ill-formed text input.
565        - Added built-in script function "change_pan_time()".
566        - Added built-in script function "change_pan_curve()".
567        - Added built-in script function "change_cutoff_attack()".
568        - Added built-in script function "change_cutoff_decay()".
569        - Added built-in script function "change_cutoff_sustain()".
570        - Added built-in script function "change_cutoff_release()".
571        - Added built-in script function "change_cutoff_lfo_depth()".
572        - Added built-in script function "change_cutoff_lfo_freq()".
573    
574      * Instruments DB:
575        - Fixed memory access bug of general DB access code which lead to
576          undefined behavior.
577        - Cleanup of instruments DB file creation and opening code.
578        - The instrument DB path of linuxsampler's --create-instruments-db argument
579          is now optional, if it is missing, then a default location is used.
580        - Added support for scanning SFZ (.sfz) files.
581        - Added support for scanning Sound Font (.sf2) files.
582        - Fixed undefined DB transaction behavior.
583    
584    Version 2.0.0 (15 July 2015)
585    
586      * packaging changes:
587        - fixed building with newer MinGW-w64
588        - Mac OS X: support the new dir for Core Audio SDK
589        - Mac OS X: fixed building outside source directory
590        - made sure all source files for hostplugins are included when
591          doing "make dist"
592        - removed empty directories left from the cvs to svn migration
593        - fixed compilation with gcc 4.6.1
594        - another "make dist" fix, for the LV2 plugin
595        - made --enable-pthread-testcancel default on Mac OS X
596        - minor Makefile fix for building lscpparser when build and source
597          directories are separate
598        - Mac OS X: made it possible to specify plugin installation dir to
599          configure
600        - Mac OS X: Makefile fix for the install-strip target
601        - fixed compilation with gcc 4.7
602        - fixed configure script error with old autoconf versions
603        - lsatomic.h: use gcc provided atomic functions if building with
604          gcc 4.7 and C++11
605        - modernized configure script
606        - fixed linkage error when building with
607          LDFLAGS="-Wl,--no-undefined" (#190)
608        - fixed compilation with Clang 3.2
609        - removed usage of deprecated Automake variable INCLUDES
610        - fixed building with C++11
611        - build fix: ChangeFlagRelaxed.h was missing in makefile
612        - build fix: libsndfile compiler flags were missing in some
613          makefiles
614        - fix for building with bison 3.0 (#202)
615        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
616          on the process's main thread
617        - fixed build error on newer MinGW
618        - support building with older jack versions
619        - support building with spaces in vst sdk path
620        - enabled automake 'subdir-objects' option and moved external
621          source references (vst, au, asio) from makefiles to cpp files,
622          in order to get rid of warnings from automake 1.14
623    
624      * general changes:
625        - Refactoring: moved the independent code from
626          the Gigasampler format engine to base classes
627        - command line option '--profile' is currently disabled, since the
628          respective profiling code is currently broken
629        - Introduced support for optional environment variable
630          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
631          where the sampler shall look for instrument editor plugins
632          (patch by Luis Garrido, slightly modified).
633        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
634        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
635        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
636          note (in this implementation of the sampler its simply hard routed to
637          the 1st effect send of the sampler channel, no matter what the actual
638          effect type is)
639        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
640          note (in this implementation of the sampler its simply hard routed to
641          the 2nd effect send of the sampler channel, no matter what the actual
642          effect type is)
643        - implemented support for internal LADSPA effects
644        - raised limit of program change queue from 100 to 512
645          (as suggested by Alex Stone)
646        - implemented sine LFO, pulse LFO and saw LFO
647        - experimental support for per voice equalization
648        - added command line option --exec-after-init
649        - Introduced new C++ API method:
650          EngineChannel::InstrumentFileName(int index)
651          allowing to retrieve the whole list of files used for the loaded
652          instrument on an engine channel (a.k.a. part). Some GigaStudio
653          instruments for example are splitted over several files like
654          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
655        - Added new C++ API method Sampler::GetGlobalMaxVoices().
656        - Added new C++ API method Sampler::GetGlobalMaxStreams().
657        - Added new C++ API method Sampler::SetGlobalMaxVoices().
658        - Added new C++ API method Sampler::SetGlobalMaxStreams().
659        - Various "const" and "restrict" optimizations.
660        - all engines: add pan CC value to instrument pan parameter before
661          applying panning, instead of using two separate pan functions in
662          series (#182)
663        - added a lock guard class for exception safe mutex handling and
664          used it everywhere appropriate
665        - Immediately apply scale tuning changes to active voices.
666        - Exposed scale tuning to C++ API (along to the already existing standard
667          SysEx way).
668        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
669          and broken for ppc64. (Seq_cst loads and stores are actually not
670          used in LS, so the bug wasn't noticable.)
671        - lsatomic.h: added ARMv7 support
672        - Added support for multiple MIDI input ports per sampler channel (and
673          added various new C++ methods for this new feature / design change, old
674          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
675          as deprecated but are still there and should provide full behavior
676          backward compatibility).
677        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
678          unsafe and caused compilation error with clang 2.x).
679        - Bugfix: only process the latest MIDI program change event.
680        - Introducing the LSCP shell, which provides convenient control of the
681          sampler from the command line by providing LSCP aware features.
682        - VirtualMidiDevice: Added support for program change.
683        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
684        - VirtualMidiDevice: Added support for pitch bend.
685        - Aftertouch: extended API to explicitly handle channel pressure and
686          polyphonic key pressure events (so far polyphonic pressure was not
687          supported at all, and channel pressure was rerouted as CC128 but not
688          used so far).
689        - Added initial support for real-time instrument scripts. The script VM
690          code is shared by all sampler engine implemementations, however only the
691          gig file format currently provides support for storing instrument scripts
692          (as LinuxSampler extension to the original GigaStudio 4 format).
693    
694      * Gigasampler format engine:
695        - implemented the "round robin keyboard" dimension
696        - fixed round robin and random dimensions for cases when number of
697          dimension zones is not a power of two
698        - made round robin use a counter for each region instead of each
699          key
700        - bugfix: pitch LFO controller "internal+aftertouch" was broken
701        - bugfix: filter keyboard tracking was broken
702        - filter performance fix (an unnecessary copy was made of the
703          filter parameters in each sub fragment)
704        - handle special case when pan parameter in gig file has max or
705          min value
706        - Exclusive Groups: don't ever stop voices of the same note,

1035          max. four function arguments are currently implemented yet though).
1036        - Implemented built-in script int variable $EVENT_ID.
1037        - Implemented built-in script function "ignore_event()"
1038        - Implemented built-in script function "ignore_controller()" (may have one
1039          or no argument).
1040        - Implemented built-in script function "set_controller()".
1041        - Added extended script VM for the Gigasampler/GigaStudio format sampler
1042          engine, which extends the general instrument script VM with Giga format
1043          specific variables and functions.
1044        - Giga format scripts: added built-in script int constant variables
1045          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,
1046          $GIG_DIM_RELEASE, $GIG_DIM_KEYBOARD, $GIG_DIM_ROUNDROBIN, $GIG_DIM_RANDOM,

1065        - Added built-in script int const variables $MARK_1 to $MARK_28.
1066        - Built-in script functions "ignore_event()", "note_off()" and
1067          "gig_set_dim_zone()" now also accept an array of event IDs as argument
1068          (i.e. return value of new script function "by_marks()").
1069        - Pass/preserve polyphonic variable data from respective "note" event
1070          handler to "release" event handler.
1071        - Fixed crash when using built-in script function "by_marks()".
1072    
1073      * Bug fixes:
1074        - Fixed crash which may occur when MIDI key + transpose is out of range
1075        - minor valgrind fixes
1076        - fixed crash which occurred when changing an already deployed sampler
1077          channel to a different engine type
1078        - fixed crash when deleting a sampler channel or changing engine
1079          type while an instrument load was in progress
1080        - bugfix: playing a note while changing the instrument could cause
1081          a crash, or give "Handing back unknown region" error messages
1082        - bugfix: calling SET VOICES (which Fantasia does on start and
1083          refresh) could cause instruments to be unloaded
1084        - Mac OS X: fixed name collision of enum in EffectControl and
1085          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1086        - Mac OS X: fixed hanging threads
1087        - Windows: disabled the previous thread fix on non-Mac systems, as
1088          it caused hanging threads on Windows
1089        - Fixed possible crashes due to corrupted MIDI/audio device list
1090          after MIDI/audio device creation failure
1091        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1092          instruments were uselessly precached with zero samples, however it still
1093          took the full preloading time and on 1st program change the respective
1094          instrument was completely reloaded again.
1095        - fixed handling of rapid bank select and program change messages
1096          sent to the same sampler channel (patch from the Open Octave
1097          project, slightly adjusted)
1098        - fixed crash when trying to create an effect instance with controls
1099          which min and/or max values depend on the sample rate
1100        - fixed bug #162
1101        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1102          multiple paths (#165)
1103        - thread safety fixes for the instrument loading thread
1104        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1105          (#176)
1106        - more thread safety fixes for the instrument loading thread
1107        - sfz/sf2 engine: fixed crash when using small audio fragment size
1108        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1109        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1110          introduced in previous fix)
1111        - fixed crash when a channel received a program change while
1112          playing a note in a key group
1113        - fixed erroneous error message piping in VoiceBase.h
1114          (labelled "Disk stream not available in time")
1115        - Update effects on sample rate & period size changes (to avoid
1116          crashes and noise on such transitions).
1117        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1118          (fixes #208)
1119        - Fixed bug in LSCP grammar definition which caused a statement like
1120          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1121          practically irrelevant, however it caused problems with the new LSCP
1122          shell's auto completion feature).
1123        - Fixed MIDI program change messages being ignored if quickly executed
1124          after each other (fixes #231).
1125    
1126    Version 1.0.0 (31 July 2009)
1127    
1128      * packaging changes:
1129        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1130          causing e.g. the libgig test to fail when
1131          "./configure --disable-jack-driver" was used
1132          (patch by Alexis Ballier)
1133        - fixed compilation with gcc 4.3
1134        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1135        - fixed configure so it detects x86_64 (#107)
1136        - fixes for building with newer MinGW versions
1137        - fix for building with bison 2.4 (#111)
1138        - fixed building with libgig installed in a non-standard directory
1139        - minor fix in configure for mmsystem.h detection on MinGW
1140        - Windows: look for editor plugins and Fantasia using base
1141          directory of liblinuxsampler dll (look in the same directory and one
1142          directory above)
1143        - configure script fix: removed unconditional use of SSE
1144        - fixed building with sqlite installed in a non-standard directory
1145        - when cross-compiling, don't try to create instruments.db
1146        - fix for new mingw-w64 version, which has usleep
1147    
1148      * general changes:
1149        - bugfix: on some POSIX systems instrument editor plugins refused to
1150          load as we used a non-portable Linux specific struct field
1151          (fixes bug #70, patch by Ronald Baljeu)
1152        - fixed endless loop which occured when loading an instrument editor
1153          plugin DLL on Windows systems failed
1154        - fixed memory leaks that occurred when liblinuxsampler was unloaded
1155        - optimized the SynchronizedConfig class so it doesn't wait
1156          unnecessarily long after an update
1157        - added support for notifying instrument editors on note-on / note-off
1158          events (e.g. to highlight the pressed keys on the virtual keyboard
1159          of gigedit)
1160        - added support for triggering notes by instrument editors (see above)
1161        - be verbose on DLL load errors (on Linux)
1162        - fixed di-harmonic triangle LFO implementation (this LFO implementation
1163          is only used by very few systems, most pick the int math
1164          implementation, which is usually faster)
1165        - fixes for audio drivers with varying buffer sizes
1166        - experimental support for running LinuxSampler as a DSSI, LV2 and
1167          VST plugin
1168        - notification events for stream/voice count statistics are now sent
1169          only when there are actual changes
1170        - added memory ordering constraints to improve stability on
1171          multi-core and multi-cpu systems
1172        - maximum voices and disk streams can now be altered at runtime
1173        - fixed CPU feature detection on x86_64 (maybe fixes #108)
1174        - automatic stacktrace mechanism is now turned off by default and can
1175          be switched on by command line option "--stacktrace" (the automatic
1176          stacktrace mechanism seems to be broken on most systems at the moment)
1177        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1178          a pointer to the launched InstrumentEditor object
1179        - added optional 3rd party user data parameter for following
1180          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1181          InstrumentEditor::Launch(),
1182          InstrumentManager::LaunchInstrumentEditor()
1183        - theoretical fix: made SynchronizedConfig follow C++0x memory
1184          model more strictly
1185        - fixes for using large audio device buffers
1186        - Windows: add the installation directory to the DLL search path
1187          when loading an editor plugin (solves problems with VST and
1188          gigedit on systems with other GTK versions installed)
1189        - updated linuxsampler man page
1190    
1191      * audio driver:
1192        - removed the nonsense audio channel constraint (which was hard coded to
1193          max. 100 audio channels) for most audio drivers
1194        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1195          opposed to the LSCP specs
1196        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1197          reflected the wrong value
1198        - fixed a memory management bug in ASIO driver
1199        - Makefile fix: JACK_CFLAGS wasn't used
1200        - JACK: use jack_client_open instead of the deprecated
1201          jack_client_new
1202        - added (experimental) CoreAudio driver
1203        - applied old fixes to the ASIO driver that were included in the
1204          previous binary release but accidentally never committed to CVS
1205          (fixes #117)
1206        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1207          win64)
1208        - VST: added support for sample rate and buffer size changes
1209        - VST: close editor (Fantasia) when the VST is removed
1210        - VST: avoid opening Fantasia more than once for each VST instance
1211        - VST: export main function as "main" on Linux too (fix for
1212          energyXT)
1213        - VST: changed number of output channels from one stereo to 16
1214          stereo
1215        - added channel routing, fxsends and midi maps to the settings
1216          stored in the plugin state
1217        - performance optimization of AudioChannel::MixTo() and
1218          AudioChannel::CopyTo() methods using GCC vector exensions
1219          (if available)
1220        - ASIO fixes: avoid initializing the device twice, avoid throwing
1221          exception when getting parameters from a disconnected device
1222    
1223      * MIDI driver:
1224        - added JACK MIDI driver
1225        - dispatch bank select as ordinary CC as well, the user might seriously
1226          want to (mis)use it for some purpose ("fixed" in all current MIDI
1227          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1228        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1229          CoreMidi or AU
1230        - fixed mingw-w64 compilation error in MME driver
1231        - made program change handling in MIDI thread real-time safe by
1232          moving the logic to a non-RT thread
1233        - fixed minor memory leak in ALSA driver
1234    
1235      * instruments database:
1236        - avoid time consuming samples scanning when adding instruments
1237          to the instruments database
1238        - added support for handling lost files in the instruments database
1239        - Implemented option for adding instruments in separate directories
1240          in the instruments database
1241          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1242        - work-around for missing fnmatch function on Windows to make
1243          instrument database compilable
1244        - added instrument database support on Windows
1245          works with both standalone mode and VST plugin.
1246          the instruments DB file is located in
1247          %USERPROFILE%\.linuxsampler\instruments.db which allows different
1248          databases for each windows user
1249          if no DB is present it automatically creates the .linuxsampler subdir
1250          and then creates an empty DB
1251        - fixed recursive import, which was broken on Windows
1252    
1253      * Gigasampler format engine:
1254        - fixed a memory leak that could happen when a channel was deleted
1255          while notes were playing
1256        - made it possible to load an instrument even if the audio thread
1257          isn't running
1258        - added partial support for the "Controller Triggered" MIDI rule,
1259          enough for piano gigs with pedal noise samples
1260        - minor fix: only mark FX sends as being modified if really the
1261          respective FX send MIDI controller was used
1262        - added support for GM global device volume SysEx message
1263          (can be selected at compile time to either apply globally to the
1264          whole sampler [default] or only to the sampler channels that are
1265          connected to the respective MIDI input port the SysEx message arrived
1266          on)
1267        - bugfix: notes triggered at position 0 in the audio buffer were
1268          sometimes wrongly killed in the same buffer, causing no sound to
1269          be played
1270        - added support for chromatic / drumkit mode Roland GS Sysex message
1271          which is usally used to switch a part between chromatic sounds and
1272          drumkit sounds (as opposed to their common default setting of MIDI
1273          part 10 being a drumkit part and all other ones chromatic parts), in
1274          LS however one can switch between the first 16 MIDI instrument maps
1275          defined for the sampler
1276        - made it possible to create multiple sample channels even if the
1277          audio thread isn't running
1278        - fixed crash when removing channel with active voices (#116)
1279        - bugfix: on sample reference changes (instrument editor), only
1280          un-cache the respective sample if it's really not used by any
1281          sampler engine anymore
1282        - re-cache samples in case they were changed by an instrument editor,
1283          e.g. when a sample was added while playing (#82)
1284        - fixed hanging notes which occured when note-off event had the exact
1285          same time stamp as the voice's note-on event and occured both in the
1286          same audio fragment cycle (fixes bug #112)
1287        - added support for the "fine tune" and "pitch bend range"
1288          instrument-level gig parameters
1289        - fixed minor artifacts in pitch bend handling
1290        - added support for GS Reset SysEx message
1291        - allow gig files to use unlimited downward pitch shifting
1292        - added a limit check for upward pitch shifting
1293        - bugfix: sometimes, when playing a note twice fast, the second
1294          note was silent
1295        - fixed crash happening when a pitch bend event arrived at the
1296          same time a new instrument was loading
1297    
1298      * LSCP server:
1299        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1300          react on MIDI data arriving on certain sampler channels (so far only
1301          Note-On and Note-Off events are sent via this LSCP event)
1302        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1303          react on MIDI data arriving on certain MIDI input devices (so far only
1304          Note-On and Note-Off events are sent via this LSCP event)
1305        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1306          SET DB_INSTRUMENT FILE_PATH
1307        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1308          frontends to send MIDI messages to specific sampler channel
1309        - added two additional fields to GET FILE INSTRUMENT INFO command -
1310          KEY_BINDINGS and KEYSWITCH_BINDINGS
1311        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1312          was incorrect
1313        - Optimized the retrieval of the MIDI instrument mappings
1314        - added new LSCP command "SET VOICES" to globally alter the maximum
1315          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1316          be triggered respectively
1317        - added new LSCP command "SET STREAMS" to globally alter the maximum
1318          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1319          which will be triggered respectively
1320        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1321          a gigedit file dialog is opened)
1322        - close all connections when LSCPServer is deleted
1323        - hard close of all sockets on exit
1324        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1325          driver
1326    
1327      * Bug fixes:
1328        - fixed a crash which occurs when removing a sampler channel waiting
1329          to start instrument loading after another channel
1330        - fixed a crash which occurs when removing a sampler channel with
1331          instrument loading in progress (bug #113)
1332        - fixed termination caused by uncaught exception when adding MIDI
1333          instrument with PERSISTENT load mode
1334        - fixed possible iterator invalidations when resetting the sampler
1335        - fixed memory leaks when issuing the following LSCP commands:
1336          GET AUDIO_OUTPUT_DRIVER INFO
1337          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1338          GET MIDI_INPUT_DRIVER INFO
1339          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1340        - fixed possible compilation error when sqlite is not present
1341        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1342        - fixed crash when changing the audio output device of a sampler
1343          channel with loaded instrument and start playing notes
1344        - fixed endless loop in Engine::SuspendAll() (bug #120)
1345        - fixed a low-level atomic load function that was broken on 64-bit
1346          PowerPC, which probably could cause crashes on that platform
1347        - fixed a memory management error which could cause a crash when a
1348          plugin was unloaded
1349        - bugfix: two private structs had the same name, which could cause
1350          problems if the linker chose the wrong constructor
1351        - fixed low-level ConditionServer usage bug that caused lockups on
1352          Windows
1353    
1354    
1355    Version 0.5.1 (6 December 2007)
1356    
1357      * packaging changes:
1358        - added autoconf checks for pthread library
1359        - added autoconf check for pthread bug found on certain NPTL-enabled
1360          glibc versions (see Gentoo bug report #194076)
1361        - added autoconf checks for MS Windows
1362    
1363      * general changes:
1364        - bugfix: the thread used by an editor plugin didn't die when the
1365          editor closed
1366        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1367          out all the space. operator--() did not apply size_mask after
1368          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1369          order to avoid problems with the _NonVolatileReader functions.
1370        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1371          GetWriteSpace(). Since this function is currently only used in
1372          the stream's qsort() compare function, it didn't trigger any
1373          bugs.
1374        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1375          24bit mode too. Faster method to read 24bit words on little
1376          endian machines (x86): replaced 3 byte reads + shifts with a 1
1377          unaligned 32bit read and shift
1378        - experimental support for MS Windows (MIDI input via MME, AUDIO
1379          output via ASIO)
1380        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1381        - support for monitoring the total number of active disk streams
1382          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1383          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1384    
1385      * AUDIO driver:
1386        - added Windows ASIO low latency audio driver
1387    
1388      * MIDI driver:
1389        - added MME Windows MIDI driver
1390    
1391      * LSCP server:
1392        - added support for Windows style path / filenames, however with
1393          forward slash path separators instead of backslash
1394          (i.e. "C:/foo/bar.gig")
