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

355        - NKSP language: Added support for bitwise operators ".or.", ".and."
356          and ".not.".
357        - NKSP language scanner: Fixed IDs matching to require at least one
358          character (i.e. when matching function names or variable names).
359        - NKSP language scanner: disabled unusued rules.
360        - Fixed behavior of play_note() and note_off() functions which must
361          be distinguished engine internally from "real" MIDI note on/off
362          events in order to avoid misbehaviors like hanging notes.
363        - Implemented built-in script variable "$KSP_TIMER".
364        - Implemented built-in script variable "$NKSP_REAL_TIMER".
365        - Implemented built-in script variable "$NKSP_PERF_TIMER".

370        - NKSP language fix: string concatenation operator was right
371          associative instead of left (to right).
372        - NKSP language correction: allow empty statements in entire language
373          (i.e. "if end if").

375        - Implemented built-in script variable "$NI_CALLBACK_ID".
376        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
377        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

389          synthesis parameter changes immediately in case the respective note
390          was triggered at the same time, instead of scheduling the parameter
391          change, especially because it would cause some parameter types's
392          changes either to be ramped (i.e. change_vol()) or other types even
393          to have not effect at all (i.e. change_attack()).

398        - NKSP Fix: "init" event handler was not always executed when a script
399          was loaded.
400        - NKSP built-in wait() script function: abort script execution if
401          a negative or zero wait time was passed as argument (since this is
402          a common indication of a bug either of the script or even of the
403          engine, which could lead to RT instability or even worse).
404        - ScriptVM: Implemented automatic suspension of RT safety
405          threatening scripts.
406        - Provide more user friendly error messages on syntax errors.
407        - Fixed NKSP parser warning "Not a statement" when assigning an

420          script functions "change_vol()", "change_tune()", "change_pan()",
421          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
422          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
423          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
424        - Added built-in script function "get_event_par()" and implemented some
425          of its possible parameter selections.
426        - Added built-in script function "set_event_par()" and implemented some
427          of its possible parameter selections.
428        - Fixed a bunch of scheduler time related bugs.
429        - Fixed polyphonic variables not being reset to zero after usage.
430        - Built-in "ignore_event()" function: argument is now optional, like with
431          built-in function "ignore_controller()".
432        - Implemented built-in script function "change_velo()".
433        - Implemented built-in script function "change_note()".
434        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
435          intuitive behavior if used in combination with "change_vol_time()" or
436          "change_tune_time()" respectively: now tuning/volume changes are only
437          assigned (without delay) immediately to a new note if the respective
438          timing function has not been called before, otherwise the volume/tuning
439          changes are automatically faded (before, only the event's time stamp was
440          relevant).
441         - Implemented built-in script function "array_equal()".
442         - Implemented built-in script function "search()".
443         - Implemented built-in script function "sort()".
444         - NKSP Fix: Never suspend "init" event handlers.
445         - Implemented built-in script function "same_region()" (currently only
446           available for gig format engine).
447         - Added built-in script constant "$NKSP_LINEAR".
448         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
449         - Implemented built-in script function "change_vol_curve()".
450         - Implemented built-in script function "change_tune_curve()".
451         - built-in "play_note()" function now supports a sample playback start
452           offset with argument 3, where special value -1 means to use the regular
453           sample offset as defined by the instrument file.
454         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
455         - Built-in variable $EVENT_NOTE is now a read-only variable.
456         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
457         - built-in "play_note()" function now accepts -2 for its fourth argument
458           (note duration) which means the life time of the note shall be sticked
459           to the requested note number of argument 1.
460         - Fix: built-in "play_note()" function now returns 0 as result value if
461           -1 was passed for its fourth argument (note duration) and the respective
462           parent note is already gone.
463        - Implemented built-in script function "change_play_pos()".
464        - NKSP language: Added support for user declared const array variables.
465        - NKSP language: Raise parser warning if array variable is accessed with
466          an index that exceeds the array's size.

468        - NKSP language: Added support for "synchronized .. end synchronized"
469          code blocks.

472        - Fixed potential memory access bug and potential undefined behavior of
473          "init" event handlers.
474        - Print a time stamp along to each call of built-in function "message()".
475        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
476          to retrieve all code blocks filtered out by the preprocessor.
477        - Added built-in script function "fork()".
478        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
479        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
480        - Fixed potential crash when accessing dynamic built-in array variables.
481        - Added built-in script function "callback_status()".
482        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
483        - Added built-in constant $CALLBACK_STATUS_QUEUE.
484        - Added built-in constant $CALLBACK_STATUS_RUNNING.
485        - Removed max. value limitation of built-in functions "change_attack()",
486          "change_decay()" and "change_release()" to i.e. allow passing 2000000
487          for doubling the respective time.
488        - NKSP script editor syntax highlighting API: Fixed app termination due
489          to a lexer start condition stack underrun.
490        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
491          USE_CODE_IF_NOT() preprocessor statements.
492        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
493          can be set to disable all subsequent built-in "message()" function calls
494          on preprocessor level.
495        - Implemented built-in script function "change_sustain()".
496        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
497          to avoid the editor app to crash on ill-formed text input.
498        - Added built-in script function "change_pan_time()".
499        - Added built-in script function "change_pan_curve()".

524          doing "make dist"
525        - removed empty directories left from the cvs to svn migration
526        - fixed compilation with gcc 4.6.1
527        - another "make dist" fix, for the LV2 plugin
528        - made --enable-pthread-testcancel default on Mac OS X
529        - minor Makefile fix for building lscpparser when build and source
530          directories are separate
531        - Mac OS X: made it possible to specify plugin installation dir to
532          configure
533        - Mac OS X: Makefile fix for the install-strip target
534        - fixed compilation with gcc 4.7
535        - fixed configure script error with old autoconf versions

550        - fixed build error on newer MinGW
551        - support building with older jack versions
552        - support building with spaces in vst sdk path
553        - enabled automake 'subdir-objects' option and moved external
554          source references (vst, au, asio) from makefiles to cpp files,
555          in order to get rid of warnings from automake 1.14
556    
557      * general changes:
558        - Refactoring: moved the independent code from
559          the Gigasampler format engine to base classes
560        - command line option '--profile' is currently disabled, since the
561          respective profiling code is currently broken
562        - Introduced support for optional environment variable
563          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
564          where the sampler shall look for instrument editor plugins
565          (patch by Luis Garrido, slightly modified).
566        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
567        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
568        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
569          note (in this implementation of the sampler its simply hard routed to
570          the 1st effect send of the sampler channel, no matter what the actual
571          effect type is)
572        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
573          note (in this implementation of the sampler its simply hard routed to
574          the 2nd effect send of the sampler channel, no matter what the actual
575          effect type is)
576        - implemented support for internal LADSPA effects
577        - raised limit of program change queue from 100 to 512
578          (as suggested by Alex Stone)
579        - implemented sine LFO, pulse LFO and saw LFO
580        - experimental support for per voice equalization
581        - added command line option --exec-after-init
582        - Introduced new C++ API method:
583          EngineChannel::InstrumentFileName(int index)
584          allowing to retrieve the whole list of files used for the loaded
585          instrument on an engine channel (a.k.a. part). Some GigaStudio
586          instruments for example are splitted over several files like
587          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
588        - Added new C++ API method Sampler::GetGlobalMaxVoices().
589        - Added new C++ API method Sampler::GetGlobalMaxStreams().
590        - Added new C++ API method Sampler::SetGlobalMaxVoices().
591        - Added new C++ API method Sampler::SetGlobalMaxStreams().
592        - Various "const" and "restrict" optimizations.
593        - all engines: add pan CC value to instrument pan parameter before
594          applying panning, instead of using two separate pan functions in
595          series (#182)
596        - added a lock guard class for exception safe mutex handling and
597          used it everywhere appropriate
598        - Immediately apply scale tuning changes to active voices.
599        - Exposed scale tuning to C++ API (along to the already existing standard
600          SysEx way).
601        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
602          and broken for ppc64. (Seq_cst loads and stores are actually not
603          used in LS, so the bug wasn't noticable.)
604        - lsatomic.h: added ARMv7 support
605        - Added support for multiple MIDI input ports per sampler channel (and
606          added various new C++ methods for this new feature / design change, old
607          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
608          as deprecated but are still there and should provide full behavior
609          backward compatibility).
610        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
611          unsafe and caused compilation error with clang 2.x).
612        - Bugfix: only process the latest MIDI program change event.
613        - Introducing the LSCP shell, which provides convenient control of the
614          sampler from the command line by providing LSCP aware features.
615        - VirtualMidiDevice: Added support for program change.
616        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
617        - VirtualMidiDevice: Added support for pitch bend.
618        - Aftertouch: extended API to explicitly handle channel pressure and
619          polyphonic key pressure events (so far polyphonic pressure was not
620          supported at all, and channel pressure was rerouted as CC128 but not
621          used so far).
622        - Added initial support for real-time instrument scripts. The script VM
623          code is shared by all sampler engine implemementations, however only the
624          gig file format currently provides support for storing instrument scripts
625          (as LinuxSampler extension to the original GigaStudio 4 format).
626    
627      * Gigasampler format engine:
628        - implemented the "round robin keyboard" dimension
629        - fixed round robin and random dimensions for cases when number of
630          dimension zones is not a power of two
631        - made round robin use a counter for each region instead of each
632          key
633        - bugfix: pitch LFO controller "internal+aftertouch" was broken
634        - bugfix: filter keyboard tracking was broken
635        - filter performance fix (an unnecessary copy was made of the
636          filter parameters in each sub fragment)
637        - handle special case when pan parameter in gig file has max or
638          min value
639        - Exclusive Groups: don't ever stop voices of the same note,
640          doesn't sound naturally with a drumkit
641        - fixed EG1 modulation when attack or release is zero
642        - Fixed support for 'aftertouch' attenuation controller.
643        - Fixed crash that happened with velocity split sounds under certain
644          conditions (see also previous commit on libgig).
645        - fixed behaviour of filter LFO
646    
647      * SFZ format engine:
648        - Initial implementation (not usable yet)
649        - added support for v2 multiple stage envelope generators
650        - added a fine-tuned v1 envelope generator instead of using the
651          one from the gig engine

653        - added support for trigger=first, trigger=legato and sw_previous
654        - allow non-numerical key values ("C#4" for example)

662        - added support for random, seq_position, seq_length and volume
663        - added v1 LFO opcodes to parser (no support in engine yet)
664        - added support for amp_veltrack and amp_velcurve_N
665        - fine-tuned the default velocity curve
666        - added support for transpose
667        - fixed crash when using sw_down/up
668        - improved logic for sw_lokey/hikey/up/down/last
669        - added more v1 aliases to parser
670        - reduced memory usage for sfz data
671        - RT-safeness: avoid malloc in audio thread
672        - fixed a bug that could cause voice stealing to fail
673        - optimized sample lookup
674        - improved support for exclusive groups (group, off_by and
675          off_mode)
676        - added support for controller triggered regions (on_locc/on_hicc)
677        - added support for loop_mode=one_shot
678        - fixed playback of 16 bit wav files on big endian CPUs
679        - added support for Ogg Vorbis sample files
680        - use loop markers from sample file if loop_start and loop_end are
681          not set in sfz file
682        - implemeted filters. Filter types: lowpass, bandpass, bandreject
683          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
684          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
685          cutoff_cc, cutoff_chanaft.
686        - bugfix: zero ampeg_sustain didn't work
687        - added support for velocity effect on amplifier envelope time
688          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
689          ampeg_vel2release)
690        - added support for EG hold (ampeg_hold)
691        - added support for sample offset (offset)
692        - use the newly introduced signal units model

826          incorrectly set to two. This caused silence in Cubase 5.
827        - save engine type (gig, sfz or sf2) in plugin state
828        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
829          64 bit Windows

884        - MME bugfix: driver wasn't closed properly
885        - CoreMIDI: automatically connect to all input sources by default (driver
886          parameter "AUTO_BIND").

1032          which min and/or max values depend on the sample rate
1033        - fixed bug #162
1034        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1035          multiple paths (#165)
1036        - thread safety fixes for the instrument loading thread
1037        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1038          (#176)

1042        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1043          introduced in previous fix)
1044        - fixed crash when a channel received a program change while
1045          playing a note in a key group
1046        - fixed erroneous error message piping in VoiceBase.h
1047          (labelled "Disk stream not available in time")
1048        - Update effects on sample rate & period size changes (to avoid
1049          crashes and noise on such transitions).
1050        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1051          (fixes #208)
1052        - Fixed bug in LSCP grammar definition which caused a statement like
1053          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1054          practically irrelevant, however it caused problems with the new LSCP
1055          shell's auto completion feature).
1056        - Fixed MIDI program change messages being ignored if quickly executed
1057          after each other (fixes #231).
