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

454        - Implemented built-in script function "change_reso()".
455        - Implemented built-in script function "event_status()".
456        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
457          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
458          "event_status()" function.
459        - NKSP language: Added support for bitwise operators ".or.", ".and."
460          and ".not.".
461        - NKSP language scanner: Fixed IDs matching to require at least one
462          character (i.e. when matching function names or variable names).
463        - NKSP language scanner: disabled unusued rules.
464        - Fixed behavior of play_note() and note_off() functions which must
465          be distinguished engine internally from "real" MIDI note on/off
466          events in order to avoid misbehaviors like hanging notes.
467        - Implemented built-in script variable "$KSP_TIMER".
468        - Implemented built-in script variable "$NKSP_REAL_TIMER".
469        - Implemented built-in script variable "$NKSP_PERF_TIMER".
470        - Implemented built-in script variable "$ENGINE_UPTIME".
471        - Implemented built-in script function "inc()".
472        - Implemented built-in script function "dec()".
473        - NKSP language fix: division expressions were evaluated too often.
474        - NKSP language fix: string concatenation operator was right
475          associative instead of left (to right).
476        - NKSP language correction: allow empty statements in entire language
477          (i.e. "if end if").
478        - Implemented built-in script function "stop_wait()".
479        - Implemented built-in script variable "$NI_CALLBACK_ID".
480        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
481        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
482        - Added support for read-only built-in variables (respectively
483          handled by the script parser).
484        - Added built-in script constant "$NI_CB_TYPE_INIT".
485        - Added built-in script constant "$NI_CB_TYPE_NOTE".
486        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

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

612        - Fixed memory access bug of general DB access code which lead to
613          undefined behavior.
614        - Cleanup of instruments DB file creation and opening code.
615        - The instrument DB path of linuxsampler's --create-instruments-db argument
616          is now optional, if it is missing, then a default location is used.
617        - Added support for scanning SFZ (.sfz) files.
618        - Added support for scanning Sound Font (.sf2) files.
619        - Fixed undefined DB transaction behavior.
620    
621    Version 2.0.0 (15 July 2015)
622    
623      * packaging changes:
624        - fixed building with newer MinGW-w64
625        - Mac OS X: support the new dir for Core Audio SDK
626        - Mac OS X: fixed building outside source directory
627        - made sure all source files for hostplugins are included when
628          doing "make dist"
629        - removed empty directories left from the cvs to svn migration
630        - fixed compilation with gcc 4.6.1
631        - another "make dist" fix, for the LV2 plugin
632        - made --enable-pthread-testcancel default on Mac OS X
633        - minor Makefile fix for building lscpparser when build and source
634          directories are separate
635        - Mac OS X: made it possible to specify plugin installation dir to
636          configure
637        - Mac OS X: Makefile fix for the install-strip target
638        - fixed compilation with gcc 4.7
639        - fixed configure script error with old autoconf versions

653          on the process's main thread
654        - fixed build error on newer MinGW
655        - support building with older jack versions
656        - support building with spaces in vst sdk path
657        - enabled automake 'subdir-objects' option and moved external
658          source references (vst, au, asio) from makefiles to cpp files,
659          in order to get rid of warnings from automake 1.14
660    
661      * general changes:
662        - Refactoring: moved the independent code from
663          the Gigasampler format engine to base classes
664        - command line option '--profile' is currently disabled, since the
665          respective profiling code is currently broken
666        - Introduced support for optional environment variable
667          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
668          where the sampler shall look for instrument editor plugins
669          (patch by Luis Garrido, slightly modified).
670        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
671        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
672        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
673          note (in this implementation of the sampler its simply hard routed to
674          the 1st effect send of the sampler channel, no matter what the actual
675          effect type is)
676        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
677          note (in this implementation of the sampler its simply hard routed to
678          the 2nd effect send of the sampler channel, no matter what the actual
679          effect type is)
680        - implemented support for internal LADSPA effects
681        - raised limit of program change queue from 100 to 512
682          (as suggested by Alex Stone)
683        - implemented sine LFO, pulse LFO and saw LFO
684        - experimental support for per voice equalization
685        - added command line option --exec-after-init
686        - Introduced new C++ API method:
687          EngineChannel::InstrumentFileName(int index)
688          allowing to retrieve the whole list of files used for the loaded
689          instrument on an engine channel (a.k.a. part). Some GigaStudio
690          instruments for example are splitted over several files like
691          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
692        - Added new C++ API method Sampler::GetGlobalMaxVoices().
693        - Added new C++ API method Sampler::GetGlobalMaxStreams().
694        - Added new C++ API method Sampler::SetGlobalMaxVoices().
695        - Added new C++ API method Sampler::SetGlobalMaxStreams().
696        - Various "const" and "restrict" optimizations.
697        - all engines: add pan CC value to instrument pan parameter before
698          applying panning, instead of using two separate pan functions in
699          series (#182)
700        - added a lock guard class for exception safe mutex handling and
701          used it everywhere appropriate
702        - Immediately apply scale tuning changes to active voices.
703        - Exposed scale tuning to C++ API (along to the already existing standard
704          SysEx way).
705        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
706          and broken for ppc64. (Seq_cst loads and stores are actually not
707          used in LS, so the bug wasn't noticable.)
708        - lsatomic.h: added ARMv7 support
709        - Added support for multiple MIDI input ports per sampler channel (and
710          added various new C++ methods for this new feature / design change, old
711          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
712          as deprecated but are still there and should provide full behavior
713          backward compatibility).
714        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
715          unsafe and caused compilation error with clang 2.x).
716        - Bugfix: only process the latest MIDI program change event.
717        - Introducing the LSCP shell, which provides convenient control of the
718          sampler from the command line by providing LSCP aware features.
719        - VirtualMidiDevice: Added support for program change.
720        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
721        - VirtualMidiDevice: Added support for pitch bend.
722        - Aftertouch: extended API to explicitly handle channel pressure and
723          polyphonic key pressure events (so far polyphonic pressure was not
724          supported at all, and channel pressure was rerouted as CC128 but not
725          used so far).
726        - Added initial support for real-time instrument scripts. The script VM
727          code is shared by all sampler engine implemementations, however only the
728          gig file format currently provides support for storing instrument scripts
729          (as LinuxSampler extension to the original GigaStudio 4 format).

741        - handle special case when pan parameter in gig file has max or
742          min value
743        - Exclusive Groups: don't ever stop voices of the same note,
744          doesn't sound naturally with a drumkit

927        - Listen to all interfaces on Mac OS X (INADDR_ANY)
928        - VST bugfix: If the host called resume() before and after
929          changing sample rate or block size, the number of channels was
930          incorrectly set to two. This caused silence in Cubase 5.
931        - save engine type (gig, sfz or sf2) in plugin state
932        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
933          64 bit Windows

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

968      * MIDI driver:
969        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
970          the ALSA sequencer client name

972          there is no reason for this limit
973        - MME: fixed memory handling bug found with cppcheck
974        - MME: removed compiler warning
975        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
976          which allows to retrieve the list of CoreMIDI clients / ports and to connect
977          to them a la JACK, via the usual sampler APIs
978        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
979          the driver will automatically connect to other CoreMIDI clients' ports

988        - MME bugfix: driver wasn't closed properly
989        - CoreMIDI: automatically connect to all input sources by default (driver
990          parameter "AUTO_BIND").
991        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
992        - CoreMIDI: fixed minor memory leak
993    
994      * audio driver:
995        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
996        - JACK audio: react on sample rate changes.
997        - JACK audio: react on buffer size changes.

999          RT context.
1000        - ASIO driver: removed compiler warnings
1001        - CoreAudio: fixed minor error handling bug
1002        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

1004          for audio device parameter "SAMPLERATE" (fixes #166).
1005    
1006      * LSCP server:

1112        - minor valgrind fixes
1113        - fixed crash which occurred when changing an already deployed sampler
1114          channel to a different engine type
1115        - fixed crash when deleting a sampler channel or changing engine
1116          type while an instrument load was in progress
1117        - bugfix: playing a note while changing the instrument could cause
1118          a crash, or give "Handing back unknown region" error messages
1119        - bugfix: calling SET VOICES (which Fantasia does on start and
1120          refresh) could cause instruments to be unloaded
1121        - Mac OS X: fixed name collision of enum in EffectControl and
1122          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1123        - Mac OS X: fixed hanging threads
1124        - Windows: disabled the previous thread fix on non-Mac systems, as
1125          it caused hanging threads on Windows
1126        - Fixed possible crashes due to corrupted MIDI/audio device list
1127          after MIDI/audio device creation failure
1128        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1129          instruments were uselessly precached with zero samples, however it still
1130          took the full preloading time and on 1st program change the respective
1131          instrument was completely reloaded again.
1132        - fixed handling of rapid bank select and program change messages
1133          sent to the same sampler channel (patch from the Open Octave
1134          project, slightly adjusted)
1135        - fixed crash when trying to create an effect instance with controls
1136          which min and/or max values depend on the sample rate
1137        - fixed bug #162
1138        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1139          multiple paths (#165)
1140        - thread safety fixes for the instrument loading thread
1141        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1142          (#176)
1143        - more thread safety fixes for the instrument loading thread
1144        - sfz/sf2 engine: fixed crash when using small audio fragment size
1145        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1146        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1147          introduced in previous fix)
1148        - fixed crash when a channel received a program change while
1149          playing a note in a key group
1150        - fixed erroneous error message piping in VoiceBase.h
1151          (labelled "Disk stream not available in time")
1152        - Update effects on sample rate & period size changes (to avoid
1153          crashes and noise on such transitions).
1154        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1155          (fixes #208)
1156        - Fixed bug in LSCP grammar definition which caused a statement like
1157          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1158          practically irrelevant, however it caused problems with the new LSCP
1159          shell's auto completion feature).
1160        - Fixed MIDI program change messages being ignored if quickly executed
1161          after each other (fixes #231).
