# 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    
136      * test cases:
137        - Fixed compiler errors in test cases.
138        - Updated README for how to compile & run test cases.
139        - Updated test case
140          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
141          expected behaviour of the Mutex class implementation (recursive
142          mutex type).
143        - Added test cases for NKSP core language aspects and core built-in
144          functions.
145        - Fixed thread tests segfaulting on Linux.
146        - NKSP: Added real number test cases for built-in functions exit(),
147          int_to_real(), real(), real_to_int() and int(), as well as for the
148          plus, minus and negate language operators.
149        - Added massive amount of NKSP test cases for standard measuring units and
150          'final' operator usage cases.
151        - Added NKSP test cases for (floating point tolerance aware) real number
152          equalness / unequalness comparison.
153    
154    Version 2.1.1 (27 Jul 2019)
155    
156      * Real-time instrument scripts:
157        - Fixed behavior of built-in NKSP functions change_sustain(),
158          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
159          and change_cutoff_release().
160    
161      * general changes:
162        - Only play release trigger samples on sustain pedal up if this behaviour
163          was explicitly requested by the instrument (otherwise only on note-off).
164        - Fixed compiler warnings.
165        - Fixed compilation error when cross-compiling to Mac.
166        - FX Sends: Provide more useful error messages on routing problems
167          (see bug #169).
168        - LSCP doc: Be more clear describing the two distinct approaches
169          of using external vs. internal effects (see bug #169).
170        - "optional" class: Fixed comparison operators.
171    
172      * Gigasampler/GigaStudio format engine:
173        - Format extension: If requested by instrument then don't play release
174          trigger sample on note-off events.
175    
176      * SFZ format engine:
177        - Fixed memory leak when releasing samples
178          (fixes bug #307, patch by Jacek Roszkowski)
179        - Fixed potential crash when a sample is shared by more than one region
180          (fixes bug #308, patch by Jacek Roszkowski).
181        - Opcode 'sample': Added support for built-in sample '*silence'
182          (fixes bug #310, patch by Jacek Roszkowski).
183    
184    Version 2.1.0 (25 Nov 2017)
185    
186      * SFZ format engine:
187        - added support for <global>, <master> and #define (patch by Alby M)
188        - Removed code duplication in SFZ file loading code.
189        - Added support for sfz extension opcode 'script' which may be used to
190          load real-time instrument script file (NKSP script language).
191        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
192        - Fixed unintended volume fade-in of voices under certain conditions.
193        - sfz parser: allow missing space between header and opcode
194    
195      * Gigasampler/GigaStudio format engine:
196        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
197          cutoff settings.
198        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
199          all if an up-pitch of more than 40 semi tones was requested (I don't
200          think there is any stock gig sound that requires this behavior to
201          resemble its original sound).
202        - Added support for controlling whether the individual EGADSR stages may
203          be aborted (as LinuxSampler extension to the original GigaStudio 4
204          format).
205    
206      * general changes:
207        - fixed printf type errors (mostly in debug messages)
208        - use unique_ptr instead of auto_ptr when building with C++11
209        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
210          allowing to sort data efficiently in real-time safe manner.
211        - RTList class: added methods for moving/inserting elements to arbitrary
212          position within a list.
213        - RTList class: added method fromPtr() for creating an Iterator object from
214          a raw element pointer.
215        - Attempt to partly fix resetting engine channels vs. resetting engine, an
216          overall cleanup of the Reset*(), ConnectAudioDevice(),
217          DisconnectAudioDevice() API methods would still be desirable though,
218          because the current situation is still inconsistent and error prone.
219        - Active voices are now internally grouped to "Note" objects, instead of
220          being directly assigned to a keyboard key. This allows more fine graded
221          processing of voices, which is i.e. required for certain instrument
222          script features.
223        - Fix: Release trigger voices were not spawned on sustain pedal up
224          (CC #64) events.
225        - Fix: Release trigger voices can now also distinguish correctly between
226          note-off and sustain pedal up events.
227        - All engines: Increased ramp speed of volume smoother and pan smoother
228          (while slow rate of crossfade smoother is preserved) to allow quick
229          volume and pan changes by instrument scripts for instance.
230        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
231          properly and thus were ignored for certain uses.
232        - Added new C++ API method
233          VirtualMidiDevice::SendChannelPressureToSampler().
234        - windows, 32-bit: fixed potential crashes by making sure the stack in
235          sub threads is 16-byte aligned
236        - fixed numerous compiler warnings
237        - Fixed invalid (note-on) event ID being assigned to new Note objects.
238        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
239          fixes potential undefined behavior.
240        - Fixed Note object leak when triggering notes on keys which did not
241          have a valid sample mapped (fixes bug #252).
242        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
243        - linuxsampler binary fix: option --create-instruments-db ignored
244          subsequent optional argument due to glibc's implementation oddity
245          which expects a "=" sign, but no space between them.
246    
247      * packaging changes:
248        - removed unnecessary dependency to libuuid
249          (originated by libgig's usage of it)
250        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
251          auto detect whether it (sh/c)ould output its messages in color.
252        - Debian: Fixed packaging error about invalid "Source-Version"
253          substitution variable.
254        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
255        - Debian: Added build dependency to libsqlite3-dev for building
256          linuxsampler with instruments DB support.
257    
258      * Real-time instrument scripts:
259        - Implemented scheduler for delayed MIDI events and for suspended scripts.
260        - Built-in script function "wait()": implemented support for function's
261          "duration-us" argument, thus scripts using this function are now
262          correctly resumed after the requested amount of microseconds.
263        - Built-in script function "play_note()": implemented support for
264          function's "duration-us" argument, thus notes triggered with this
265          argument are now correctly released after the requested amount of
266          microseconds.
267        - Fix: script events were not cleared when engine channel was reset,
268          potentially causing undefined behavior.
269        - Fixed crash which happened when trying to reference an undeclared
270          variable.
271        - Built-in script function "play_note()": Added support for passing
272          special value -1 for "duration-us" argument, which will cause the
273          triggered note to be released once the original note was released.
274        - Instrument script classes now exported with the liblinuxsampler C++ API.
275        - Added new API method ScriptVM::syntaxHighlighting() which provides
276          a convenient syntax highlighting backend for external instrument
277          script editor applications.
278        - Added new C++ API class "ScriptVMFactory".
279        - Extended parser issues to provide not only first line and first
280          column, but also last line and last column of issue (thus marking
281          the precise span of the issue within the source code).
282        - Reload script automatically after being modified by an instrument
283          editor.
284        - NKSP language grammar correction: allow empty event handler bodies
285          like "on note end on".
286        - Implemented built-in script function "change_vol()".
287        - Implemented built-in script function "change_tune()".
288        - Implemented built-in script function "change_pan()".
289        - Implemented built-in script function "change_cutoff()".
290        - Implemented built-in script function "change_reso()".
291        - Implemented built-in script function "event_status()".
292        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
293          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
294          "event_status()" function.
295        - NKSP language: Added support for bitwise operators ".or.", ".and."
296          and ".not.".
297        - NKSP language scanner: Fixed IDs matching to require at least one
298          character (i.e. when matching function names or variable names).
299        - NKSP language scanner: disabled unusued rules.
300        - Fixed behavior of play_note() and note_off() functions which must
301          be distinguished engine internally from "real" MIDI note on/off
302          events in order to avoid misbehaviors like hanging notes.
303        - Implemented built-in script variable "$KSP_TIMER".
304        - Implemented built-in script variable "$NKSP_REAL_TIMER".
305        - Implemented built-in script variable "$NKSP_PERF_TIMER".
306        - Implemented built-in script variable "$ENGINE_UPTIME".
307        - Implemented built-in script function "inc()".
308        - Implemented built-in script function "dec()".
309        - NKSP language fix: division expressions were evaluated too often.
310        - NKSP language fix: string concatenation operator was right
311          associative instead of left (to right).
312        - NKSP language correction: allow empty statements in entire language
313          (i.e. "if end if").
314        - Implemented built-in script function "stop_wait()".
315        - Implemented built-in script variable "$NI_CALLBACK_ID".
316        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
317        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
318        - Added support for read-only built-in variables (respectively
319          handled by the script parser).
320        - Added built-in script constant "$NI_CB_TYPE_INIT".
321        - Added built-in script constant "$NI_CB_TYPE_NOTE".
322        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
323        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
324        - NKSP Language: Added support for user defined script functions.
325        - Implemented built-in script function "change_attack()".
326        - Implemented built-in script function "change_decay()".
327        - Implemented built-in script function "change_release()".
328        - Fixed all change_*() built-in script functions to apply their
329          synthesis parameter changes immediately in case the respective note
330          was triggered at the same time, instead of scheduling the parameter
331          change, especially because it would cause some parameter types's
332          changes either to be ramped (i.e. change_vol()) or other types even
333          to have not effect at all (i.e. change_attack()).
334        - Implemented built-in script function "sh_left()".
335        - Implemented built-in script function "sh_right()".
336        - Implemented built-in script function "min()".
337        - Implemented built-in script function "max()".
338        - NKSP Fix: "init" event handler was not always executed when a script
339          was loaded.
340        - NKSP built-in wait() script function: abort script execution if
341          a negative or zero wait time was passed as argument (since this is
342          a common indication of a bug either of the script or even of the
343          engine, which could lead to RT instability or even worse).
344        - ScriptVM: Implemented automatic suspension of RT safety
345          threatening scripts.
346        - Provide more user friendly error messages on syntax errors.
347        - Fixed NKSP parser warning "Not a statement" when assigning an
348          initializer list to an array variable.
349        - Implemented built-in script array variable "%ALL_EVENTS".
350        - Implemented built-in script function "in_range()".
351        - Implemented built-in script function "change_amp_lfo_depth()".
352        - Implemented built-in script function "change_amp_lfo_freq()".
353        - Implemented built-in script function "change_pitch_lfo_depth()".
354        - Implemented built-in script function "change_pitch_lfo_freq()".
355        - Implemented built-in script function "change_vol_time()".
356        - Implemented built-in script function "change_tune_time()".
357        - Implemented built-in script function "fade_in()".
358        - Implemented built-in script function "fade_out()".
359        - Fixed acceptance of wrong data type of parameters passed to built-in
360          script functions "change_vol()", "change_tune()", "change_pan()",
361          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
362          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
363          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".

375          intuitive behavior if used in combination with "change_vol_time()" or
376          "change_tune_time()" respectively: now tuning/volume changes are only
377          assigned (without delay) immediately to a new note if the respective
378          timing function has not been called before, otherwise the volume/tuning
379          changes are automatically faded (before, only the event's time stamp was

391         - built-in "play_note()" function now supports a sample playback start
392           offset with argument 3, where special value -1 means to use the regular
393           sample offset as defined by the instrument file.
394         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
395         - Built-in variable $EVENT_NOTE is now a read-only variable.

397         - built-in "play_note()" function now accepts -2 for its fourth argument
398           (note duration) which means the life time of the note shall be sticked
399           to the requested note number of argument 1.
400         - Fix: built-in "play_note()" function now returns 0 as result value if
401           -1 was passed for its fourth argument (note duration) and the respective
402           parent note is already gone.
403        - Implemented built-in script function "change_play_pos()".
404        - NKSP language: Added support for user declared const array variables.

412        - Fixed potential memory access bug and potential undefined behavior of
413          "init" event handlers.
414        - Print a time stamp along to each call of built-in function "message()".
415        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
416          to retrieve all code blocks filtered out by the preprocessor.
417        - Added built-in script function "fork()".
418        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].

420        - Fixed potential crash when accessing dynamic built-in array variables.
421        - Added built-in script function "callback_status()".
422        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
423        - Added built-in constant $CALLBACK_STATUS_QUEUE.
424        - Added built-in constant $CALLBACK_STATUS_RUNNING.
425        - Removed max. value limitation of built-in functions "change_attack()",
426          "change_decay()" and "change_release()" to i.e. allow passing 2000000
427          for doubling the respective time.
428        - NKSP script editor syntax highlighting API: Fixed app termination due
429          to a lexer start condition stack underrun.
430        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
431          USE_CODE_IF_NOT() preprocessor statements.
432        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
433          can be set to disable all subsequent built-in "message()" function calls
434          on preprocessor level.
435        - Implemented built-in script function "change_sustain()".
436        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
437          to avoid the editor app to crash on ill-formed text input.
438        - Added built-in script function "change_pan_time()".
439        - Added built-in script function "change_pan_curve()".

466        - fixed compilation with gcc 4.6.1
467        - another "make dist" fix, for the LV2 plugin
468        - made --enable-pthread-testcancel default on Mac OS X
469        - minor Makefile fix for building lscpparser when build and source
470          directories are separate
471        - Mac OS X: made it possible to specify plugin installation dir to

491        - support building with older jack versions
492        - support building with spaces in vst sdk path
493        - enabled automake 'subdir-objects' option and moved external
494          source references (vst, au, asio) from makefiles to cpp files,
495          in order to get rid of warnings from automake 1.14
496    
497      * general changes:
498        - Refactoring: moved the independent code from
499          the Gigasampler format engine to base classes
500        - command line option '--profile' is currently disabled, since the
501          respective profiling code is currently broken
502        - Introduced support for optional environment variable
503          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
504          where the sampler shall look for instrument editor plugins
505          (patch by Luis Garrido, slightly modified).
506        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
507        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
508        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
509          note (in this implementation of the sampler its simply hard routed to
510          the 1st effect send of the sampler channel, no matter what the actual
511          effect type is)
512        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
513          note (in this implementation of the sampler its simply hard routed to
514          the 2nd effect send of the sampler channel, no matter what the actual
515          effect type is)
516        - implemented support for internal LADSPA effects
517        - raised limit of program change queue from 100 to 512
518          (as suggested by Alex Stone)
519        - implemented sine LFO, pulse LFO and saw LFO
520        - experimental support for per voice equalization
521        - added command line option --exec-after-init
522        - Introduced new C++ API method:
523          EngineChannel::InstrumentFileName(int index)
524          allowing to retrieve the whole list of files used for the loaded
525          instrument on an engine channel (a.k.a. part). Some GigaStudio
526          instruments for example are splitted over several files like
527          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
528        - Added new C++ API method Sampler::GetGlobalMaxVoices().
529        - Added new C++ API method Sampler::GetGlobalMaxStreams().
530        - Added new C++ API method Sampler::SetGlobalMaxVoices().
531        - Added new C++ API method Sampler::SetGlobalMaxStreams().
532        - Various "const" and "restrict" optimizations.
533        - all engines: add pan CC value to instrument pan parameter before
534          applying panning, instead of using two separate pan functions in
535          series (#182)
536        - added a lock guard class for exception safe mutex handling and
537          used it everywhere appropriate
538        - Immediately apply scale tuning changes to active voices.
539        - Exposed scale tuning to C++ API (along to the already existing standard
540          SysEx way).
541        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
542          and broken for ppc64. (Seq_cst loads and stores are actually not
543          used in LS, so the bug wasn't noticable.)
544        - lsatomic.h: added ARMv7 support
545        - Added support for multiple MIDI input ports per sampler channel (and
546          added various new C++ methods for this new feature / design change, old
547          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
548          as deprecated but are still there and should provide full behavior
549          backward compatibility).
550        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
551          unsafe and caused compilation error with clang 2.x).
552        - Bugfix: only process the latest MIDI program change event.
553        - Introducing the LSCP shell, which provides convenient control of the
554          sampler from the command line by providing LSCP aware features.
555        - VirtualMidiDevice: Added support for program change.
556        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
557        - VirtualMidiDevice: Added support for pitch bend.
558        - Aftertouch: extended API to explicitly handle channel pressure and
559          polyphonic key pressure events (so far polyphonic pressure was not
560          supported at all, and channel pressure was rerouted as CC128 but not
561          used so far).
562        - Added initial support for real-time instrument scripts. The script VM
563          code is shared by all sampler engine implemementations, however only the
564          gig file format currently provides support for storing instrument scripts
565          (as LinuxSampler extension to the original GigaStudio 4 format).
566    
567      * Gigasampler format engine:
568        - implemented the "round robin keyboard" dimension
569        - fixed round robin and random dimensions for cases when number of
570          dimension zones is not a power of two

572          key
573        - bugfix: pitch LFO controller "internal+aftertouch" was broken
574        - bugfix: filter keyboard tracking was broken
575        - filter performance fix (an unnecessary copy was made of the
576          filter parameters in each sub fragment)
577        - handle special case when pan parameter in gig file has max or
578          min value
579        - Exclusive Groups: don't ever stop voices of the same note,
580          doesn't sound naturally with a drumkit
581        - fixed EG1 modulation when attack or release is zero
582        - Fixed support for 'aftertouch' attenuation controller.
583        - Fixed crash that happened with velocity split sounds under certain
584          conditions (see also previous commit on libgig).
585        - fixed behaviour of filter LFO

604        - added support for amp_veltrack and amp_velcurve_N
605        - fine-tuned the default velocity curve
606        - added support for transpose
607        - fixed crash when using sw_down/up
608        - improved logic for sw_lokey/hikey/up/down/last
609        - added more v1 aliases to parser
610        - reduced memory usage for sfz data
611        - RT-safeness: avoid malloc in audio thread
612        - fixed a bug that could cause voice stealing to fail
613        - optimized sample lookup
614        - improved support for exclusive groups (group, off_by and
615          off_mode)

620        - use loop markers from sample file if loop_start and loop_end are
621          not set in sfz file
622        - implemeted filters. Filter types: lowpass, bandpass, bandreject

625          cutoff_cc, cutoff_chanaft.
626        - bugfix: zero ampeg_sustain didn't work
627        - added support for velocity effect on amplifier envelope time

734          used
735        - bugfix: looping was disabled if loop_start was set to 0
736        - allow regions with end=-1 to turn off other regions using the

762        - AU bugfix: failed to destroy its audio/MIDI devices
763        - Listen to all interfaces on Mac OS X (INADDR_ANY)
764        - VST bugfix: If the host called resume() before and after
765          changing sample rate or block size, the number of channels was
766          incorrectly set to two. This caused silence in Cubase 5.
767        - save engine type (gig, sfz or sf2) in plugin state
768        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
769          64 bit Windows
770        - AU: changed number of output channels from one stereo to 16
771          stereo

784          Linux, the Fantasia jar should be placed in <prefix>/share/java)
785        - VST: fixed crashes on Linux Ardour and EnergyXT
786        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

800          informations like the EngineChannel for which the instrument editor was
801          spawned for. This allows the instrument editors to interact more actively
802          with the sampler.
803    
804      * MIDI driver:
805        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
806          the ALSA sequencer client name

808          there is no reason for this limit
809        - MME: fixed memory handling bug found with cppcheck
810        - MME: removed compiler warning
811        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
812          which allows to retrieve the list of CoreMIDI clients / ports and to connect
813          to them a la JACK, via the usual sampler APIs
814        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
815          the driver will automatically connect to other CoreMIDI clients' ports

822        - Implemented missing handling of MIDI "running status".
823        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
824        - MME bugfix: driver wasn't closed properly
825        - CoreMIDI: automatically connect to all input sources by default (driver
826          parameter "AUTO_BIND").
827        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
828        - CoreMIDI: fixed minor memory leak
829    
830      * audio driver:
831        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
832        - JACK audio: react on sample rate changes.

835          RT context.
836        - ASIO driver: removed compiler warnings
837        - CoreAudio: fixed minor error handling bug
838        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

891        - Added support for built-in LSCP reference documentation, which will
892          automatically show the relevant LSCP reference section on screen as soon
893          as one specific LSCP command was detected while typing on the command

963          after MIDI/audio device creation failure
964        - When creating MIDI instrument map entries with "PERSISTENT" type, the
965          instruments were uselessly precached with zero samples, however it still
966          took the full preloading time and on 1st program change the respective
967          instrument was completely reloaded again.
968        - fixed handling of rapid bank select and program change messages
969          sent to the same sampler channel (patch from the Open Octave

983          introduced in previous fix)
984        - fixed crash when a channel received a program change while
985          playing a note in a key group
986        - fixed erroneous error message piping in VoiceBase.h
987          (labelled "Disk stream not available in time")
988        - Update effects on sample rate & period size changes (to avoid
989          crashes and noise on such transitions).
990        - ignore missing LADSPA paths without ignoring valid LADSPA paths
991          (fixes #208)
992        - Fixed bug in LSCP grammar definition which caused a statement like
993          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
994          practically irrelevant, however it caused problems with the new LSCP
995          shell's auto completion feature).
996        - Fixed MIDI program change messages being ignored if quickly executed
997          after each other (fixes #231).
