# 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    
154      * test cases:
155        - Fixed compiler errors in test cases.
156        - Updated README for how to compile & run test cases.
157        - Updated test case
158          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
159          expected behaviour of the Mutex class implementation (recursive
160          mutex type).
161        - Added test cases for NKSP core language aspects and core built-in
162          functions.
163        - Fixed thread tests segfaulting on Linux.
164        - NKSP: Added real number test cases for built-in functions exit(),
165          int_to_real(), real(), real_to_int() and int(), as well as for the
166          plus, minus and negate language operators.
167        - Added massive amount of NKSP test cases for standard measuring units and
168          'final' operator usage cases.
169        - Added NKSP test cases for (floating point tolerance aware) real number
170          equalness / unequalness comparison.
171        - Added NKSP int array and real array tests for value assignment and
172          initialization of arrays.
173    
174    Version 2.1.1 (27 Jul 2019)
175    
176      * Real-time instrument scripts:
177        - Fixed behavior of built-in NKSP functions change_sustain(),
178          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
179          and change_cutoff_release().
180    
181      * general changes:
182        - Only play release trigger samples on sustain pedal up if this behaviour
183          was explicitly requested by the instrument (otherwise only on note-off).
184        - Fixed compiler warnings.
185        - Fixed compilation error when cross-compiling to Mac.
186        - FX Sends: Provide more useful error messages on routing problems
187          (see bug #169).
188        - LSCP doc: Be more clear describing the two distinct approaches
189          of using external vs. internal effects (see bug #169).
190        - "optional" class: Fixed comparison operators.
191    
192      * Gigasampler/GigaStudio format engine:
193        - Format extension: If requested by instrument then don't play release
194          trigger sample on note-off events.
195    
196      * SFZ format engine:
197        - Fixed memory leak when releasing samples
198          (fixes bug #307, patch by Jacek Roszkowski)
199        - Fixed potential crash when a sample is shared by more than one region
200          (fixes bug #308, patch by Jacek Roszkowski).
201        - Opcode 'sample': Added support for built-in sample '*silence'
202          (fixes bug #310, patch by Jacek Roszkowski).
203    
204    Version 2.1.0 (25 Nov 2017)
205    
206      * SFZ format engine:
207        - added support for <global>, <master> and #define (patch by Alby M)
208        - Removed code duplication in SFZ file loading code.
209        - Added support for sfz extension opcode 'script' which may be used to
210          load real-time instrument script file (NKSP script language).
211        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
212        - Fixed unintended volume fade-in of voices under certain conditions.
213        - sfz parser: allow missing space between header and opcode
214    
215      * Gigasampler/GigaStudio format engine:
216        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
217          cutoff settings.
218        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
219          all if an up-pitch of more than 40 semi tones was requested (I don't
220          think there is any stock gig sound that requires this behavior to
221          resemble its original sound).
222        - Added support for controlling whether the individual EGADSR stages may
223          be aborted (as LinuxSampler extension to the original GigaStudio 4
224          format).
225    
226      * general changes:
227        - fixed printf type errors (mostly in debug messages)
228        - use unique_ptr instead of auto_ptr when building with C++11
229        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
230          allowing to sort data efficiently in real-time safe manner.
231        - RTList class: added methods for moving/inserting elements to arbitrary
232          position within a list.
233        - RTList class: added method fromPtr() for creating an Iterator object from
234          a raw element pointer.
235        - Attempt to partly fix resetting engine channels vs. resetting engine, an
236          overall cleanup of the Reset*(), ConnectAudioDevice(),
237          DisconnectAudioDevice() API methods would still be desirable though,
238          because the current situation is still inconsistent and error prone.
239        - Active voices are now internally grouped to "Note" objects, instead of
240          being directly assigned to a keyboard key. This allows more fine graded
241          processing of voices, which is i.e. required for certain instrument
242          script features.
243        - Fix: Release trigger voices were not spawned on sustain pedal up
244          (CC #64) events.
245        - Fix: Release trigger voices can now also distinguish correctly between
246          note-off and sustain pedal up events.
247        - All engines: Increased ramp speed of volume smoother and pan smoother
248          (while slow rate of crossfade smoother is preserved) to allow quick
249          volume and pan changes by instrument scripts for instance.
250        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
251          properly and thus were ignored for certain uses.
252        - Added new C++ API method
253          VirtualMidiDevice::SendChannelPressureToSampler().
254        - windows, 32-bit: fixed potential crashes by making sure the stack in
255          sub threads is 16-byte aligned
256        - fixed numerous compiler warnings
257        - Fixed invalid (note-on) event ID being assigned to new Note objects.
258        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
259          fixes potential undefined behavior.
260        - Fixed Note object leak when triggering notes on keys which did not
261          have a valid sample mapped (fixes bug #252).
262        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
263        - linuxsampler binary fix: option --create-instruments-db ignored
264          subsequent optional argument due to glibc's implementation oddity
265          which expects a "=" sign, but no space between them.
266    
267      * packaging changes:
268        - removed unnecessary dependency to libuuid
269          (originated by libgig's usage of it)
270        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
271          auto detect whether it (sh/c)ould output its messages in color.
272        - Debian: Fixed packaging error about invalid "Source-Version"
273          substitution variable.
274        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
275        - Debian: Added build dependency to libsqlite3-dev for building
276          linuxsampler with instruments DB support.
277    
278      * Real-time instrument scripts:
279        - Implemented scheduler for delayed MIDI events and for suspended scripts.
280        - Built-in script function "wait()": implemented support for function's
281          "duration-us" argument, thus scripts using this function are now
282          correctly resumed after the requested amount of microseconds.
283        - Built-in script function "play_note()": implemented support for
284          function's "duration-us" argument, thus notes triggered with this
285          argument are now correctly released after the requested amount of
286          microseconds.
287        - Fix: script events were not cleared when engine channel was reset,
288          potentially causing undefined behavior.
289        - Fixed crash which happened when trying to reference an undeclared
290          variable.
291        - Built-in script function "play_note()": Added support for passing
292          special value -1 for "duration-us" argument, which will cause the
293          triggered note to be released once the original note was released.
294        - Instrument script classes now exported with the liblinuxsampler C++ API.
295        - Added new API method ScriptVM::syntaxHighlighting() which provides
296          a convenient syntax highlighting backend for external instrument
297          script editor applications.
298        - Added new C++ API class "ScriptVMFactory".
299        - Extended parser issues to provide not only first line and first
300          column, but also last line and last column of issue (thus marking
301          the precise span of the issue within the source code).
302        - Reload script automatically after being modified by an instrument
303          editor.
304        - NKSP language grammar correction: allow empty event handler bodies
305          like "on note end on".
306        - Implemented built-in script function "change_vol()".
307        - Implemented built-in script function "change_tune()".
308        - Implemented built-in script function "change_pan()".
309        - Implemented built-in script function "change_cutoff()".
310        - Implemented built-in script function "change_reso()".
311        - Implemented built-in script function "event_status()".
312        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
313          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
314          "event_status()" function.
315        - NKSP language: Added support for bitwise operators ".or.", ".and."
316          and ".not.".
317        - NKSP language scanner: Fixed IDs matching to require at least one
318          character (i.e. when matching function names or variable names).
319        - NKSP language scanner: disabled unusued rules.
320        - Fixed behavior of play_note() and note_off() functions which must
321          be distinguished engine internally from "real" MIDI note on/off
322          events in order to avoid misbehaviors like hanging notes.
323        - Implemented built-in script variable "$KSP_TIMER".
324        - Implemented built-in script variable "$NKSP_REAL_TIMER".
325        - Implemented built-in script variable "$NKSP_PERF_TIMER".
326        - Implemented built-in script variable "$ENGINE_UPTIME".
327        - Implemented built-in script function "inc()".
328        - Implemented built-in script function "dec()".
329        - NKSP language fix: division expressions were evaluated too often.
330        - NKSP language fix: string concatenation operator was right
331          associative instead of left (to right).
332        - NKSP language correction: allow empty statements in entire language
333          (i.e. "if end if").
334        - Implemented built-in script function "stop_wait()".
335        - Implemented built-in script variable "$NI_CALLBACK_ID".
336        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
337        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
338        - Added support for read-only built-in variables (respectively
339          handled by the script parser).
340        - Added built-in script constant "$NI_CB_TYPE_INIT".
341        - Added built-in script constant "$NI_CB_TYPE_NOTE".
342        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
343        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
344        - NKSP Language: Added support for user defined script functions.
345        - Implemented built-in script function "change_attack()".
346        - Implemented built-in script function "change_decay()".
347        - Implemented built-in script function "change_release()".
348        - Fixed all change_*() built-in script functions to apply their
349          synthesis parameter changes immediately in case the respective note
350          was triggered at the same time, instead of scheduling the parameter
351          change, especially because it would cause some parameter types's
352          changes either to be ramped (i.e. change_vol()) or other types even
353          to have not effect at all (i.e. change_attack()).
354        - Implemented built-in script function "sh_left()".
355        - Implemented built-in script function "sh_right()".
356        - Implemented built-in script function "min()".
357        - Implemented built-in script function "max()".
358        - NKSP Fix: "init" event handler was not always executed when a script
359          was loaded.
360        - NKSP built-in wait() script function: abort script execution if
361          a negative or zero wait time was passed as argument (since this is
362          a common indication of a bug either of the script or even of the
363          engine, which could lead to RT instability or even worse).
364        - ScriptVM: Implemented automatic suspension of RT safety
365          threatening scripts.
366        - Provide more user friendly error messages on syntax errors.

381          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
382          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
383          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".

395          intuitive behavior if used in combination with "change_vol_time()" or
396          "change_tune_time()" respectively: now tuning/volume changes are only
397          assigned (without delay) immediately to a new note if the respective
398          timing function has not been called before, otherwise the volume/tuning
399          changes are automatically faded (before, only the event's time stamp was
400          relevant).
401         - Implemented built-in script function "array_equal()".

412           offset with argument 3, where special value -1 means to use the regular
413           sample offset as defined by the instrument file.
414         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
415         - Built-in variable $EVENT_NOTE is now a read-only variable.

417         - built-in "play_note()" function now accepts -2 for its fourth argument
418           (note duration) which means the life time of the note shall be sticked
419           to the requested note number of argument 1.
420         - Fix: built-in "play_note()" function now returns 0 as result value if
421           -1 was passed for its fourth argument (note duration) and the respective
422           parent note is already gone.
423        - Implemented built-in script function "change_play_pos()".

433          "init" event handlers.
434        - Print a time stamp along to each call of built-in function "message()".

436          to retrieve all code blocks filtered out by the preprocessor.
437        - Added built-in script function "fork()".
438        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].

440        - Fixed potential crash when accessing dynamic built-in array variables.
441        - Added built-in script function "callback_status()".
442        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
443        - Added built-in constant $CALLBACK_STATUS_QUEUE.
444        - Added built-in constant $CALLBACK_STATUS_RUNNING.
445        - Removed max. value limitation of built-in functions "change_attack()",
446          "change_decay()" and "change_release()" to i.e. allow passing 2000000
447          for doubling the respective time.
448        - NKSP script editor syntax highlighting API: Fixed app termination due
449          to a lexer start condition stack underrun.
450        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
451          USE_CODE_IF_NOT() preprocessor statements.
452        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which

454          on preprocessor level.
455        - Implemented built-in script function "change_sustain()".

526        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
527        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
528        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
529          note (in this implementation of the sampler its simply hard routed to
530          the 1st effect send of the sampler channel, no matter what the actual
531          effect type is)
532        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per

536        - implemented support for internal LADSPA effects
537        - raised limit of program change queue from 100 to 512
538          (as suggested by Alex Stone)
539        - implemented sine LFO, pulse LFO and saw LFO
540        - experimental support for per voice equalization
541        - added command line option --exec-after-init
542        - Introduced new C++ API method:
543          EngineChannel::InstrumentFileName(int index)
544          allowing to retrieve the whole list of files used for the loaded
545          instrument on an engine channel (a.k.a. part). Some GigaStudio
546          instruments for example are splitted over several files like
547          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
548        - Added new C++ API method Sampler::GetGlobalMaxVoices().
549        - Added new C++ API method Sampler::GetGlobalMaxStreams().
550        - Added new C++ API method Sampler::SetGlobalMaxVoices().
551        - Added new C++ API method Sampler::SetGlobalMaxStreams().
552        - Various "const" and "restrict" optimizations.
553        - all engines: add pan CC value to instrument pan parameter before
554          applying panning, instead of using two separate pan functions in
555          series (#182)
556        - added a lock guard class for exception safe mutex handling and
557          used it everywhere appropriate
558        - Immediately apply scale tuning changes to active voices.
559        - Exposed scale tuning to C++ API (along to the already existing standard
560          SysEx way).
561        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
562          and broken for ppc64. (Seq_cst loads and stores are actually not
563          used in LS, so the bug wasn't noticable.)
564        - lsatomic.h: added ARMv7 support
565        - Added support for multiple MIDI input ports per sampler channel (and
566          added various new C++ methods for this new feature / design change, old
567          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
568          as deprecated but are still there and should provide full behavior
569          backward compatibility).
570        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
571          unsafe and caused compilation error with clang 2.x).
572        - Bugfix: only process the latest MIDI program change event.
573        - Introducing the LSCP shell, which provides convenient control of the
574          sampler from the command line by providing LSCP aware features.
575        - VirtualMidiDevice: Added support for program change.
576        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
577        - VirtualMidiDevice: Added support for pitch bend.
578        - Aftertouch: extended API to explicitly handle channel pressure and
579          polyphonic key pressure events (so far polyphonic pressure was not
580          supported at all, and channel pressure was rerouted as CC128 but not
581          used so far).
582        - Added initial support for real-time instrument scripts. The script VM
583          code is shared by all sampler engine implemementations, however only the
584          gig file format currently provides support for storing instrument scripts
585          (as LinuxSampler extension to the original GigaStudio 4 format).

987          instrument was completely reloaded again.
988        - fixed handling of rapid bank select and program change messages

1010        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1011          (fixes #208)
1012        - Fixed bug in LSCP grammar definition which caused a statement like
1013          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1014          practically irrelevant, however it caused problems with the new LSCP
1015          shell's auto completion feature).
1016        - Fixed MIDI program change messages being ignored if quickly executed
1017          after each other (fixes #231).
