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        - Implemented support for compressed RPN/NRPN message sequences (that is to
42          allow processing MIDI data entry messages without always having to be
43          preceded strictly by RPN/NRPN parameter selection messages on each value
44          change).
45        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46          decrement).
47        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48          MSB=127 and LSB=127) and which is disabling subsequent data
49          entry/increment/decrement CC messages.
50        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51          instrument editor.
52        - Fixed playing noise at the end of a disk stream under certain conditions.
53        - Fixed potential crash with high pitch at end of RAM playback.
54        - Added configure checks whether C++ compiler supports so called
55          'designated initializers'.
56    
57      * Real-time instrument scripts:
58        - Added method ScriptVM::setExitResultEnabled() which allows to
59          explicitly enable the built-in exit() function to optionally accept
60          one function argument; the value of the passed exit() function
61          argument will then become available by calling
62          VMExecContext::exitResult() after script execution.
63        - 64 bit support for NKSP integer scripts variables (declare $foo).
64        - Variable names, function names and preprocessor condition names must start
65          with a regular character (a-z or A-Z); starting them with a digit or
66          underscore is not allowed.
67        - NKSP parser fix: equal comparison operator "=" and not equal comparison
68          operator "#" must only accept integer operands.
69        - NKSP language: Implemented support for standard units like Hertz, seconds,
70          Bel including support for metric unit prefixes; so one can now e.g.
71          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
72          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
73          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
74        - NKSP language: Introduced "final" operator "!" which is specifically
75          intended for synthesis parameter values to denote that the synthesis
76          parameter value is intended to be the "final" value for that synthesis
77          parameter that should explicitly be used by the engine and thus causing
78          the sampler engine to ignore all other modulation sources for the same
79          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
80          variable or formula with this new "!" operator the expression is marked as
81          being "final".
82        - NKSP script editor API: Added support for detecting standard unit tokens
83          and their potential metric prefix token.
84        - NKSP language: Added support for NKSP real number literals and
85          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
86        - NKSP language: Added support for NKSP real number (floating point) script
87          variables (declare ~foo).
88        - NKSP language: Added support for NKSP real number (floating point) array
89          script variables (declare ?foo[]).
90        - Built-in script function "message()" accepts now real number argument as
91          well.
92        - Added built-in script function "real_to_int()" and its short hand form
93          "int()" for casting from real number to integer in NKSP scripts.
94        - Added built-in script function "int_to_real()" and its short hand form
95          "real()" for casting from integer to real number in NKSP scripts.
96        - Allow built-in exit() function to potentially accept real number type
97          argument as well.
98        - Built-in script functions may have a different return type depending on
99          the arguments passed to the function.
100        - Built-in script function "abs()" optionally accepts and returns real
101          number.
102        - Built-in script functions "min()" and "max()" optionally accept real
103          number arguments and return real number as result in that case.
104        - NKSP VM API: Allow units and 'final'ness to be returned as result from
105          built-in functions (added methods VMFunction::returnUnitType() and
106          VMFunction::returnsFinal() for that purpose which must be implemented by
107          built-in function implementations).
108        - NKSP language: Allow metric unit prefixes of numeric scalar and array
109          variables to be changed freely at runtime (unlike unit types like Hz etc.
110          which are still sticky, parse-time features of variables which cannot be
111          changed at runtime for the intentional sake of determinism).
112        - NKSP language: 'final' values are prohibited for array variables for now
113          (attempt causes a parsers error).
114        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
115          conditions of runtime control structures like if(), while(), select()
116          (attempt causes a parser error).
117        - NKSP VM API: Allow built-in functions to perform their own, individual
118          parse time checks of arguments going to be passed to the function at
119          runtime (added method VMFunction::checkArgs() for that purpose).
120        - NKSP language: raise parser warning if only one operand of binary
121          operators (like logical 'or' comparison) contain a 'final' value (because
122          it would always yield in a 'final' result in such cases).
123        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
124          different metric unit prefixes, which will behave as expected (e.g.
125          result of expression '1000us < 2ms' is true).
126        - NKSP language: Allow adding values with different metric unit prefixes
127          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
128        - NKSP language: Allow subtracting values with different metric unit
129          prefixes (e.g. result of expression '1ms - 20us' is '980us').
130        - NKSP language: Allow multiplying with any metric unit prefixes
131          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
132          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
133          we don't have any considerable practical use for a term like '4s^2'
134          (hence any attempt multiplying two unit types still causes parser error).
135        - NKSP language: Allow dividing by any metric unit prefixes and allow
136          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
137          yields in unit free result '8'). So this is now a way to cast units away
138          e.g. for passing the result to other expressions, certain function calls
139          or variables which are not accepting any units (or that specific unit).
140        - NKSP language: integer arrays and real number arrays can now be converted
141          to strings (e.g. for dumping their content with message() calls for
142          script debugging purposes).
143        - NKSP language: expressions and variables with units are now correctly
144          casted to strings (e.g. with message() calls).
145        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
146          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
147          floating point tolerances into account.
148        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
149          VMScalarNumberExpr::evalCastReal().
150        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
151          'VMIntArrayExpr' and 'VMRealArrayExpr'.
152        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
153          unitFactor() (runtime) methods.
154        - Built-in function "exit()" supports now returning units and 'final'ness
155          for test cases.
156        - The following built-in functions support now units as well: "abs()",
157          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
158          "real_to_int()", "int()", "int_to_real()" and "real()".
159        - Built-in functions "array_equal()", "search()" and "sort()" support now
160          real number arrays (correctly) as well.
161        - Added individual parse time checks of arguments to be passed to built-in
162          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
163          "array_equal()" and "search()" specific for their individual purposes.
164        - NKSP VM refactoring: Renamed all methods, functions and classes matching
165          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
166          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
167          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
168          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
169          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
170          isScalarNumber() -> isNumber()).
171        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
172          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
173          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
174          as convenient methods for automatically converting values to expected
175          metric value basis.
176        - Built-in function "wait()" accepts now both integers and real numbers as
177          argument.
178        - NKSP VM API cleanup: Get rid of legacy method
179          VMFunction::argType(vmint iArg) which was already superseded by its new
180          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
181        - NKSP parser: if wrong argument type was passed to a built-in function and
182          that built-in function accepts more than one data type for the argument,
183          then show all supported data types as parser error message.
184        - Built-in function "play_note()" accepts now real numbers and seconds as
185          unit type as well for its 3rd and 4th function arguments.
186        - The following built-in functions accept now real numbers as well for their
187          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
188          "change_attack()", "change_decay()", "change_release()",
189          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
190          "change_cutoff_sustain()", "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()", "fade_in()", "fade_out()", "change_play_pos()".
194        - Fixed built-in function "change_play_pos()" not having accepted metric
195          prefixes at all.
196        - Fixed the following built-in functions having misinterpreted values given
197          with unit type (for their 2nd argument) as if they were relative values
198          (that is as if they were passed without a unit type): "change_attack()",
199          "change_decay()", "change_release()", "change_cutoff_attack()",
200          "change_cutoff_decay()", "change_cutoff_release()".
201        - Fixed the following built-in functions having applied completely wrong
202          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
203          respective EGs being their modulation sink assume uint data type with
204          value range 0..1000 instead of 0.0..1.0.
205        - Added individual parse-time checks of function arguments for the following
206          built-in functions: "play_note()", "note_off()", "set_event_mark()",
207          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
208          "change_decay()", "change_release()", "change_cutoff_attack()",
209          "change_cutoff_decay()", "change_cutoff_release()",
210          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
211          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
212          "change_pan_time()".
213        - Don't abort function call if unit type was used and at the same time
214          'final' operator was omitted for the primary value argument of the
215          following built-in functions: "change_cutoff()", "change_attack()",
216          "change_decay()", "change_release()", "change_cutoff_attack()",
217          "change_cutoff_decay()", "change_cutoff_release()",
218          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
219          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
220          "change_pan_time()", instead imply 'final'ness at runtime and raise an
221          appropriate parser warning at parse time.
222        - Added built-in real number functions "round()", "ceil()", "floor()",
223          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
224          "cos()", "tan()", "asin()", "acos()", "atan()".
225        - Added built-in script real number constant "~NI_MATH_PI".
226        - Added built-in script real number constant "~NI_MATH_E".
227        - NKSP language: Allow unary '+' operator.
228        - Added built-in script functions "msb()" and "lsb()".
229        - NKSP language: Added support for RPN event handler
230          ("on rpn ... end on" in instrument scripts).
231        - NKSP language: Added support for NRPN event handler
232          ("on nrpn ... end on" in instrument scripts).
233        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
234          may be read from the new RPN/NRPN script handlers to get the (N)RPN
235          parameter that had been changed and its new value.
236        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
237          which are identifying the new (N)RPN handlers as such at script runtime.
238        - Implemented built-in script function "set_rpn()".
239        - Implemented built-in script function "set_nrpn()".
240        - Fix: built-in functions returning an array type were broken and caused a
241          crash when the built-in function's (supposed to be array) result value was
242          used by the script VM.
243        - Removed upper value constraint for 2nd argument of built-in functions
244          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
245          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
246          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
247          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
248          the LFO frequency / resonance / cutoff frequency.
249        - Reduced code involved for parsing NKSP variable declarations by using 2
250          generalized grammar rules with optional components (i.e. optional value
251          assignment and optional variable qualifiers) instead of previous linear
252          combinations of grammar rules, which also fixes some edge case.
253        - NKSP language parser: track code block locations also by a) raw byte
254          position in NKSP source code string and b) length of that code block in
255          bytes (along to the already existing code block tracking by line/column);
256          and added appropriate new members to public C++ API classes like
257          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
258        - NKSP language: Added support for 'patch' variable qualifier (capture their
259          locations and allow replacement of their assignment expression via VM C++
260          API).
261        - Fixed incorrect EG times if standard measuring unit was passed to built-in
262          functions "change_attack()", "change_decay()" or "change_release()".
263        - Fixed intermediate function result values never having reflected any
264          standard measuring unit type.
265    
266      * test cases:
267        - Fixed compiler errors in test cases.
268        - Updated README for how to compile & run test cases.
269        - Updated test case
270          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
271          expected behaviour of the Mutex class implementation (recursive
272          mutex type).
273        - Added test cases for NKSP core language aspects and core built-in
274          functions.
275        - Fixed thread tests segfaulting on Linux.
276        - NKSP: Added real number test cases for built-in functions exit(),
277          int_to_real(), real(), real_to_int() and int(), as well as for the
278          plus, minus and negate language operators.
279        - Added massive amount of NKSP test cases for standard measuring units and
280          'final' operator usage cases.
281        - Added NKSP test cases for (floating point tolerance aware) real number
282          equalness / unequalness comparison.
283        - Added NKSP int array and real array tests for value assignment and
284          initialization of arrays.
285        - Added NKSP test cases for built-in functions "round()", "ceil()",
286          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
287          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
288        - Added NKSP test cases for unary '+' operator.
289        - Added NKSP test cases for core built-in variables.
290        - Added thorough NKSP test cases for variable declarations.
291    
292      * GigaStudio/Gigasampler format engine:
293        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
294          behaviour for start_level_mid.
295        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
296          level (see discussion "GigaStudio LFO compatibility" on mailing list
297          from 2019-09-26 for details).
298        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
299          see discussion "GigaStudio LFO compatibility" on mailing list from
300          2019-09-26 for details).
301        - Format extension: Added support for different LFO wave forms (currently
302          either sine [default], triangle, saw or square).
303        - Format extension: Added support for LFO phase displacement (0°..360°).
304        - Format extension: Added support for flipping LFO polarity on LFO 3
305          (in the original gig format this was only available for LFO 1 and LFO 2).
306        - Format extension: Support for additional filter types:
307          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
308          bandreject 2-pole.
309        - Fixd potential crash with polynomial interpolator and max. pitch.
310        - If minimum cutoff is defined, remap cutoff controller CC values to really
311          span the entire possible cutoff range (and avoiding a dead controller
312          zone).
313        - Implemented support for loading instrument scripts with 'patch' variables
314          (by patching these script variables with potentially overridden ones by
315          gig Instrument).
316    
317      * SFZ format engine:
318        - Fixed support for regions with loccN/hiccN conditions on more than one
319          MIDI controller.
320    
321      * Benchmarks:
322        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
323          algorithm (since result of 2nd run was not accumulated).
324        - Added benchmark for saw wave (benchmarks/saw.cpp).
325        - Added benchmark for sine wave (benchmarks/sine.cpp).
326        - Added benchmark for square wave (benchmarks/square.cpp).
327        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
328          which are large enough on modern systems.
329    
330    Version 2.1.1 (27 Jul 2019)
331    
332      * Real-time instrument scripts:
333        - Fixed behavior of built-in NKSP functions change_sustain(),
334          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
335          and change_cutoff_release().
336    
337      * general changes:
338        - Only play release trigger samples on sustain pedal up if this behaviour
339          was explicitly requested by the instrument (otherwise only on note-off).
340        - Fixed compiler warnings.
341        - Fixed compilation error when cross-compiling to Mac.
342        - FX Sends: Provide more useful error messages on routing problems
343          (see bug #169).
344        - LSCP doc: Be more clear describing the two distinct approaches
345          of using external vs. internal effects (see bug #169).
346        - "optional" class: Fixed comparison operators.
347    
348      * Gigasampler/GigaStudio format engine:
349        - Format extension: If requested by instrument then don't play release
350          trigger sample on note-off events.
351    
352      * SFZ format engine:
353        - Fixed memory leak when releasing samples
354          (fixes bug #307, patch by Jacek Roszkowski)
355        - Fixed potential crash when a sample is shared by more than one region
356          (fixes bug #308, patch by Jacek Roszkowski).
357        - Opcode 'sample': Added support for built-in sample '*silence'
358          (fixes bug #310, patch by Jacek Roszkowski).
359    
360    Version 2.1.0 (25 Nov 2017)
361    
362      * SFZ format engine:
363        - added support for <global>, <master> and #define (patch by Alby M)
364        - Removed code duplication in SFZ file loading code.
365        - Added support for sfz extension opcode 'script' which may be used to
366          load real-time instrument script file (NKSP script language).
367        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
368        - Fixed unintended volume fade-in of voices under certain conditions.
369        - sfz parser: allow missing space between header and opcode
370    
371      * Gigasampler/GigaStudio format engine:
372        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
373          cutoff settings.
374        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
375          all if an up-pitch of more than 40 semi tones was requested (I don't
376          think there is any stock gig sound that requires this behavior to
377          resemble its original sound).
378        - Added support for controlling whether the individual EGADSR stages may
379          be aborted (as LinuxSampler extension to the original GigaStudio 4
380          format).
381    
382      * general changes:
383        - fixed printf type errors (mostly in debug messages)
384        - use unique_ptr instead of auto_ptr when building with C++11
385        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
386          allowing to sort data efficiently in real-time safe manner.
387        - RTList class: added methods for moving/inserting elements to arbitrary
388          position within a list.
389        - RTList class: added method fromPtr() for creating an Iterator object from
390          a raw element pointer.
391        - Attempt to partly fix resetting engine channels vs. resetting engine, an
392          overall cleanup of the Reset*(), ConnectAudioDevice(),
393          DisconnectAudioDevice() API methods would still be desirable though,
394          because the current situation is still inconsistent and error prone.
395        - Active voices are now internally grouped to "Note" objects, instead of
396          being directly assigned to a keyboard key. This allows more fine graded
397          processing of voices, which is i.e. required for certain instrument
398          script features.
399        - Fix: Release trigger voices were not spawned on sustain pedal up
400          (CC #64) events.
401        - Fix: Release trigger voices can now also distinguish correctly between
402          note-off and sustain pedal up events.
403        - All engines: Increased ramp speed of volume smoother and pan smoother
404          (while slow rate of crossfade smoother is preserved) to allow quick
405          volume and pan changes by instrument scripts for instance.
406        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
407          properly and thus were ignored for certain uses.
408        - Added new C++ API method
409          VirtualMidiDevice::SendChannelPressureToSampler().
410        - windows, 32-bit: fixed potential crashes by making sure the stack in
411          sub threads is 16-byte aligned
412        - fixed numerous compiler warnings
413        - Fixed invalid (note-on) event ID being assigned to new Note objects.
414        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
415          fixes potential undefined behavior.
416        - Fixed Note object leak when triggering notes on keys which did not
417          have a valid sample mapped (fixes bug #252).
418        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
419        - linuxsampler binary fix: option --create-instruments-db ignored
420          subsequent optional argument due to glibc's implementation oddity
421          which expects a "=" sign, but no space between them.
422    
423      * packaging changes:
424        - removed unnecessary dependency to libuuid
425          (originated by libgig's usage of it)
426        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
427          auto detect whether it (sh/c)ould output its messages in color.
428        - Debian: Fixed packaging error about invalid "Source-Version"
429          substitution variable.
430        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
431        - Debian: Added build dependency to libsqlite3-dev for building
432          linuxsampler with instruments DB support.
433    
434      * Real-time instrument scripts:
435        - Implemented scheduler for delayed MIDI events and for suspended scripts.
436        - Built-in script function "wait()": implemented support for function's
437          "duration-us" argument, thus scripts using this function are now
438          correctly resumed after the requested amount of microseconds.
439        - Built-in script function "play_note()": implemented support for
440          function's "duration-us" argument, thus notes triggered with this
441          argument are now correctly released after the requested amount of
442          microseconds.
443        - Fix: script events were not cleared when engine channel was reset,
444          potentially causing undefined behavior.
445        - Fixed crash which happened when trying to reference an undeclared
446          variable.
447        - Built-in script function "play_note()": Added support for passing
448          special value -1 for "duration-us" argument, which will cause the
449          triggered note to be released once the original note was released.
450        - Instrument script classes now exported with the liblinuxsampler C++ API.
451        - Added new API method ScriptVM::syntaxHighlighting() which provides
452          a convenient syntax highlighting backend for external instrument
453          script editor applications.
454        - Added new C++ API class "ScriptVMFactory".
455        - Extended parser issues to provide not only first line and first
456          column, but also last line and last column of issue (thus marking
457          the precise span of the issue within the source code).
458        - Reload script automatically after being modified by an instrument
459          editor.
460        - NKSP language grammar correction: allow empty event handler bodies
461          like "on note end on".
462        - Implemented built-in script function "change_vol()".
463        - Implemented built-in script function "change_tune()".
464        - Implemented built-in script function "change_pan()".
465        - Implemented built-in script function "change_cutoff()".
466        - Implemented built-in script function "change_reso()".
467        - Implemented built-in script function "event_status()".
468        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
469          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
470          "event_status()" function.
471        - NKSP language: Added support for bitwise operators ".or.", ".and."
472          and ".not.".
473        - NKSP language scanner: Fixed IDs matching to require at least one
474          character (i.e. when matching function names or variable names).
475        - NKSP language scanner: disabled unusued rules.
476        - Fixed behavior of play_note() and note_off() functions which must
477          be distinguished engine internally from "real" MIDI note on/off
478          events in order to avoid misbehaviors like hanging notes.
479        - Implemented built-in script variable "$KSP_TIMER".
480        - Implemented built-in script variable "$NKSP_REAL_TIMER".
481        - Implemented built-in script variable "$NKSP_PERF_TIMER".
482        - Implemented built-in script variable "$ENGINE_UPTIME".
483        - Implemented built-in script function "inc()".
484        - Implemented built-in script function "dec()".
485        - NKSP language fix: division expressions were evaluated too often.
486        - NKSP language fix: string concatenation operator was right
487          associative instead of left (to right).
488        - NKSP language correction: allow empty statements in entire language
489          (i.e. "if end if").
490        - Implemented built-in script function "stop_wait()".
491        - Implemented built-in script variable "$NI_CALLBACK_ID".
492        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
493        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
494        - Added support for read-only built-in variables (respectively
495          handled by the script parser).
496        - Added built-in script constant "$NI_CB_TYPE_INIT".
497        - Added built-in script constant "$NI_CB_TYPE_NOTE".
498        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

502        - Implemented built-in script function "change_decay()".
503        - Implemented built-in script function "change_release()".
504        - Fixed all change_*() built-in script functions to apply their
505          synthesis parameter changes immediately in case the respective note
506          was triggered at the same time, instead of scheduling the parameter
507          change, especially because it would cause some parameter types's
508          changes either to be ramped (i.e. change_vol()) or other types even
509          to have not effect at all (i.e. change_attack()).
510        - Implemented built-in script function "sh_left()".
511        - Implemented built-in script function "sh_right()".
512        - Implemented built-in script function "min()".
513        - Implemented built-in script function "max()".
514        - NKSP Fix: "init" event handler was not always executed when a script
515          was loaded.
516        - NKSP built-in wait() script function: abort script execution if
517          a negative or zero wait time was passed as argument (since this is
518          a common indication of a bug either of the script or even of the
519          engine, which could lead to RT instability or even worse).
520        - ScriptVM: Implemented automatic suspension of RT safety
521          threatening scripts.
522        - Provide more user friendly error messages on syntax errors.
523        - Fixed NKSP parser warning "Not a statement" when assigning an
524          initializer list to an array variable.
525        - Implemented built-in script array variable "%ALL_EVENTS".
526        - Implemented built-in script function "in_range()".
527        - Implemented built-in script function "change_amp_lfo_depth()".
528        - Implemented built-in script function "change_amp_lfo_freq()".
529        - Implemented built-in script function "change_pitch_lfo_depth()".
530        - Implemented built-in script function "change_pitch_lfo_freq()".
531        - Implemented built-in script function "change_vol_time()".
532        - Implemented built-in script function "change_tune_time()".
533        - Implemented built-in script function "fade_in()".
534        - Implemented built-in script function "fade_out()".
535        - Fixed acceptance of wrong data type of parameters passed to built-in
536          script functions "change_vol()", "change_tune()", "change_pan()",
537          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
538          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
539          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
540        - Added built-in script function "get_event_par()" and implemented some
541          of its possible parameter selections.
542        - Added built-in script function "set_event_par()" and implemented some
543          of its possible parameter selections.
544        - Fixed a bunch of scheduler time related bugs.
545        - Fixed polyphonic variables not being reset to zero after usage.
546        - Built-in "ignore_event()" function: argument is now optional, like with
547          built-in function "ignore_controller()".
548        - Implemented built-in script function "change_velo()".
549        - Implemented built-in script function "change_note()".
550        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
551          intuitive behavior if used in combination with "change_vol_time()" or
552          "change_tune_time()" respectively: now tuning/volume changes are only
553          assigned (without delay) immediately to a new note if the respective
554          timing function has not been called before, otherwise the volume/tuning
555          changes are automatically faded (before, only the event's time stamp was
556          relevant).
557         - Implemented built-in script function "array_equal()".
558         - Implemented built-in script function "search()".
559         - Implemented built-in script function "sort()".
560         - NKSP Fix: Never suspend "init" event handlers.
561         - Implemented built-in script function "same_region()" (currently only
562           available for gig format engine).
563         - Added built-in script constant "$NKSP_LINEAR".
564         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
565         - Implemented built-in script function "change_vol_curve()".
566         - Implemented built-in script function "change_tune_curve()".
567         - built-in "play_note()" function now supports a sample playback start
568           offset with argument 3, where special value -1 means to use the regular
569           sample offset as defined by the instrument file.
570         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
571         - Built-in variable $EVENT_NOTE is now a read-only variable.
572         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
573         - built-in "play_note()" function now accepts -2 for its fourth argument
574           (note duration) which means the life time of the note shall be sticked
575           to the requested note number of argument 1.
576         - Fix: built-in "play_note()" function now returns 0 as result value if
577           -1 was passed for its fourth argument (note duration) and the respective
578           parent note is already gone.
579        - Implemented built-in script function "change_play_pos()".
580        - NKSP language: Added support for user declared const array variables.
581        - NKSP language: Raise parser warning if array variable is accessed with
582          an index that exceeds the array's size.
583        - NKSP language fix: Unknown characters were not handled correctly.
584        - NKSP language: Added support for "synchronized .. end synchronized"
585          code blocks.
586        - Implemented built-in script function "abort()" which allows to abort
587          another script handler by passing its callback ID.
588        - Fixed potential memory access bug and potential undefined behavior of
589          "init" event handlers.
590        - Print a time stamp along to each call of built-in function "message()".
591        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
592          to retrieve all code blocks filtered out by the preprocessor.
593        - Added built-in script function "fork()".
594        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
595        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
596        - Fixed potential crash when accessing dynamic built-in array variables.
597        - Added built-in script function "callback_status()".
598        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
599        - Added built-in constant $CALLBACK_STATUS_QUEUE.
600        - Added built-in constant $CALLBACK_STATUS_RUNNING.
601        - Removed max. value limitation of built-in functions "change_attack()",
602          "change_decay()" and "change_release()" to i.e. allow passing 2000000
603          for doubling the respective time.
604        - NKSP script editor syntax highlighting API: Fixed app termination due
605          to a lexer start condition stack underrun.
606        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
607          USE_CODE_IF_NOT() preprocessor statements.
608        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
609          can be set to disable all subsequent built-in "message()" function calls
610          on preprocessor level.
611        - Implemented built-in script function "change_sustain()".
612        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
613          to avoid the editor app to crash on ill-formed text input.
614        - Added built-in script function "change_pan_time()".
615        - Added built-in script function "change_pan_curve()".

621        - Added built-in script function "change_cutoff_lfo_freq()".
622    
623      * Instruments DB:
624        - Fixed memory access bug of general DB access code which lead to
625          undefined behavior.
626        - Cleanup of instruments DB file creation and opening code.
627        - The instrument DB path of linuxsampler's --create-instruments-db argument
628          is now optional, if it is missing, then a default location is used.
629        - Added support for scanning SFZ (.sfz) files.
630        - Added support for scanning Sound Font (.sf2) files.
631        - Fixed undefined DB transaction behavior.
632    
633    Version 2.0.0 (15 July 2015)
634    
635      * packaging changes:
636        - fixed building with newer MinGW-w64
637        - Mac OS X: support the new dir for Core Audio SDK
638        - Mac OS X: fixed building outside source directory
639        - made sure all source files for hostplugins are included when
640          doing "make dist"
641        - removed empty directories left from the cvs to svn migration
642        - fixed compilation with gcc 4.6.1
643        - another "make dist" fix, for the LV2 plugin
644        - made --enable-pthread-testcancel default on Mac OS X
645        - minor Makefile fix for building lscpparser when build and source
646          directories are separate
647        - Mac OS X: made it possible to specify plugin installation dir to
648          configure
649        - Mac OS X: Makefile fix for the install-strip target
650        - fixed compilation with gcc 4.7
651        - fixed configure script error with old autoconf versions

653          gcc 4.7 and C++11
654        - modernized configure script
655        - fixed linkage error when building with
656          LDFLAGS="-Wl,--no-undefined" (#190)
657        - fixed compilation with Clang 3.2
658        - removed usage of deprecated Automake variable INCLUDES

660        - build fix: ChangeFlagRelaxed.h was missing in makefile
661        - build fix: libsndfile compiler flags were missing in some
662          makefiles

664        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
665          on the process's main thread
666        - fixed build error on newer MinGW
667        - support building with older jack versions
668        - support building with spaces in vst sdk path
669        - enabled automake 'subdir-objects' option and moved external
670          source references (vst, au, asio) from makefiles to cpp files,
671          in order to get rid of warnings from automake 1.14
672    
673      * general changes:
674        - Refactoring: moved the independent code from
675          the Gigasampler format engine to base classes
676        - command line option '--profile' is currently disabled, since the
677          respective profiling code is currently broken
678        - Introduced support for optional environment variable
679          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
680          where the sampler shall look for instrument editor plugins
681          (patch by Luis Garrido, slightly modified).
682        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
683        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
684        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
685          note (in this implementation of the sampler its simply hard routed to
686          the 1st effect send of the sampler channel, no matter what the actual
687          effect type is)
688        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
689          note (in this implementation of the sampler its simply hard routed to
690          the 2nd effect send of the sampler channel, no matter what the actual
691          effect type is)
692        - implemented support for internal LADSPA effects
693        - raised limit of program change queue from 100 to 512
694          (as suggested by Alex Stone)
695        - implemented sine LFO, pulse LFO and saw LFO
696        - experimental support for per voice equalization
697        - added command line option --exec-after-init
698        - Introduced new C++ API method:
699          EngineChannel::InstrumentFileName(int index)
700          allowing to retrieve the whole list of files used for the loaded
701          instrument on an engine channel (a.k.a. part). Some GigaStudio
702          instruments for example are splitted over several files like
703          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
704        - Added new C++ API method Sampler::GetGlobalMaxVoices().
705        - Added new C++ API method Sampler::GetGlobalMaxStreams().
706        - Added new C++ API method Sampler::SetGlobalMaxVoices().
707        - Added new C++ API method Sampler::SetGlobalMaxStreams().
708        - Various "const" and "restrict" optimizations.
709        - all engines: add pan CC value to instrument pan parameter before
710          applying panning, instead of using two separate pan functions in
711          series (#182)
712        - added a lock guard class for exception safe mutex handling and
713          used it everywhere appropriate
714        - Immediately apply scale tuning changes to active voices.
715        - Exposed scale tuning to C++ API (along to the already existing standard
716          SysEx way).
717        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
718          and broken for ppc64. (Seq_cst loads and stores are actually not
719          used in LS, so the bug wasn't noticable.)
720        - lsatomic.h: added ARMv7 support
721        - Added support for multiple MIDI input ports per sampler channel (and
722          added various new C++ methods for this new feature / design change, old
723          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
724          as deprecated but are still there and should provide full behavior
725          backward compatibility).
726        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
727          unsafe and caused compilation error with clang 2.x).
728        - Bugfix: only process the latest MIDI program change event.
729        - Introducing the LSCP shell, which provides convenient control of the
730          sampler from the command line by providing LSCP aware features.
731        - VirtualMidiDevice: Added support for program change.
732        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
733        - VirtualMidiDevice: Added support for pitch bend.
734        - Aftertouch: extended API to explicitly handle channel pressure and
735          polyphonic key pressure events (so far polyphonic pressure was not
736          supported at all, and channel pressure was rerouted as CC128 but not
737          used so far).
738        - Added initial support for real-time instrument scripts. The script VM
739          code is shared by all sampler engine implemementations, however only the
740          gig file format currently provides support for storing instrument scripts
741          (as LinuxSampler extension to the original GigaStudio 4 format).

754          min value
755        - Exclusive Groups: don't ever stop voices of the same note,
756          doesn't sound naturally with a drumkit

940        - VST bugfix: If the host called resume() before and after
941          changing sample rate or block size, the number of channels was
942          incorrectly set to two. This caused silence in Cubase 5.
943        - save engine type (gig, sfz or sf2) in plugin state
944        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
945          64 bit Windows

961        - VST: fixed crashes on Linux Ardour and EnergyXT
962        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

984          there is no reason for this limit
985        - MME: fixed memory handling bug found with cppcheck
986        - MME: removed compiler warning
987        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
988          which allows to retrieve the list of CoreMIDI clients / ports and to connect
989          to them a la JACK, via the usual sampler APIs
990        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
991          the driver will automatically connect to other CoreMIDI clients' ports

1000        - MME bugfix: driver wasn't closed properly
1001        - CoreMIDI: automatically connect to all input sources by default (driver
1002          parameter "AUTO_BIND").
1003        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
1004        - CoreMIDI: fixed minor memory leak
1005    
1006      * audio driver:
1007        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
1008        - JACK audio: react on sample rate changes.

1011          RT context.
1012        - ASIO driver: removed compiler warnings
1013        - CoreAudio: fixed minor error handling bug
1014        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

1016          for audio device parameter "SAMPLERATE" (fixes #166).
1017    
1018      * LSCP server:

1125        - fixed crash which occurred when changing an already deployed sampler
1126          channel to a different engine type
1127        - fixed crash when deleting a sampler channel or changing engine
1128          type while an instrument load was in progress
1129        - bugfix: playing a note while changing the instrument could cause
1130          a crash, or give "Handing back unknown region" error messages
1131        - bugfix: calling SET VOICES (which Fantasia does on start and
1132          refresh) could cause instruments to be unloaded
1133        - Mac OS X: fixed name collision of enum in EffectControl and
1134          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1135        - Mac OS X: fixed hanging threads
1136        - Windows: disabled the previous thread fix on non-Mac systems, as
1137          it caused hanging threads on Windows
1138        - Fixed possible crashes due to corrupted MIDI/audio device list
1139          after MIDI/audio device creation failure
1140        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1141          instruments were uselessly precached with zero samples, however it still
1142          took the full preloading time and on 1st program change the respective
1143          instrument was completely reloaded again.
1144        - fixed handling of rapid bank select and program change messages
1145          sent to the same sampler channel (patch from the Open Octave
1146          project, slightly adjusted)
1147        - fixed crash when trying to create an effect instance with controls
1148          which min and/or max values depend on the sample rate
1149        - fixed bug #162
1150        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1151          multiple paths (#165)
1152        - thread safety fixes for the instrument loading thread
1153        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1154          (#176)
1155        - more thread safety fixes for the instrument loading thread
1156        - sfz/sf2 engine: fixed crash when using small audio fragment size
1157        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1158        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1159          introduced in previous fix)
1160        - fixed crash when a channel received a program change while
1161          playing a note in a key group
1162        - fixed erroneous error message piping in VoiceBase.h
1163          (labelled "Disk stream not available in time")
1164        - Update effects on sample rate & period size changes (to avoid
1165          crashes and noise on such transitions).
1166        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1167          (fixes #208)
1168        - Fixed bug in LSCP grammar definition which caused a statement like
1169          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1170          practically irrelevant, however it caused problems with the new LSCP
1171          shell's auto completion feature).
1172        - Fixed MIDI program change messages being ignored if quickly executed
1173          after each other (fixes #231).
