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

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

400           offset with argument 3, where special value -1 means to use the regular
401           sample offset as defined by the instrument file.
402         - Built-in array variable %KEY_DOWN[] is now a read-only variable.

405         - built-in "play_note()" function now accepts -2 for its fourth argument
406           (note duration) which means the life time of the note shall be sticked
407           to the requested note number of argument 1.
408         - Fix: built-in "play_note()" function now returns 0 as result value if
409           -1 was passed for its fourth argument (note duration) and the respective
410           parent note is already gone.
411        - Implemented built-in script function "change_play_pos()".

420        - Fixed potential memory access bug and potential undefined behavior of
421          "init" event handlers.
422        - Print a time stamp along to each call of built-in function "message()".

430        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
431        - Added built-in constant $CALLBACK_STATUS_QUEUE.
432        - Added built-in constant $CALLBACK_STATUS_RUNNING.
433        - Removed max. value limitation of built-in functions "change_attack()",
434          "change_decay()" and "change_release()" to i.e. allow passing 2000000
435          for doubling the respective time.
436        - NKSP script editor syntax highlighting API: Fixed app termination due
437          to a lexer start condition stack underrun.
438        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
439          USE_CODE_IF_NOT() preprocessor statements.
440        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which

442          on preprocessor level.
443        - Implemented built-in script function "change_sustain()".

474        - fixed compilation with gcc 4.6.1
475        - another "make dist" fix, for the LV2 plugin
476        - made --enable-pthread-testcancel default on Mac OS X
477        - minor Makefile fix for building lscpparser when build and source
478          directories are separate
479        - Mac OS X: made it possible to specify plugin installation dir to

499        - support building with older jack versions
500        - support building with spaces in vst sdk path
501        - enabled automake 'subdir-objects' option and moved external
502          source references (vst, au, asio) from makefiles to cpp files,
503          in order to get rid of warnings from automake 1.14
504    
505      * general changes:
506        - Refactoring: moved the independent code from
507          the Gigasampler format engine to base classes
508        - command line option '--profile' is currently disabled, since the
509          respective profiling code is currently broken
510        - Introduced support for optional environment variable
511          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
512          where the sampler shall look for instrument editor plugins
513          (patch by Luis Garrido, slightly modified).
514        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
515        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
516        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
517          note (in this implementation of the sampler its simply hard routed to
518          the 1st effect send of the sampler channel, no matter what the actual
519          effect type is)
520        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
521          note (in this implementation of the sampler its simply hard routed to
522          the 2nd effect send of the sampler channel, no matter what the actual
523          effect type is)
524        - implemented support for internal LADSPA effects
525        - raised limit of program change queue from 100 to 512
526          (as suggested by Alex Stone)
527        - implemented sine LFO, pulse LFO and saw LFO
528        - experimental support for per voice equalization
529        - added command line option --exec-after-init
530        - Introduced new C++ API method:
531          EngineChannel::InstrumentFileName(int index)
532          allowing to retrieve the whole list of files used for the loaded
533          instrument on an engine channel (a.k.a. part). Some GigaStudio
534          instruments for example are splitted over several files like
535          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
536        - Added new C++ API method Sampler::GetGlobalMaxVoices().
537        - Added new C++ API method Sampler::GetGlobalMaxStreams().
538        - Added new C++ API method Sampler::SetGlobalMaxVoices().
539        - Added new C++ API method Sampler::SetGlobalMaxStreams().
540        - Various "const" and "restrict" optimizations.
541        - all engines: add pan CC value to instrument pan parameter before
542          applying panning, instead of using two separate pan functions in
543          series (#182)
544        - added a lock guard class for exception safe mutex handling and
545          used it everywhere appropriate
546        - Immediately apply scale tuning changes to active voices.
547        - Exposed scale tuning to C++ API (along to the already existing standard
548          SysEx way).
549        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
550          and broken for ppc64. (Seq_cst loads and stores are actually not
551          used in LS, so the bug wasn't noticable.)
552        - lsatomic.h: added ARMv7 support
553        - Added support for multiple MIDI input ports per sampler channel (and
554          added various new C++ methods for this new feature / design change, old
555          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
556          as deprecated but are still there and should provide full behavior
557          backward compatibility).
558        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
559          unsafe and caused compilation error with clang 2.x).
560        - Bugfix: only process the latest MIDI program change event.
561        - Introducing the LSCP shell, which provides convenient control of the
562          sampler from the command line by providing LSCP aware features.
563        - VirtualMidiDevice: Added support for program change.
564        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
565        - VirtualMidiDevice: Added support for pitch bend.
566        - Aftertouch: extended API to explicitly handle channel pressure and
567          polyphonic key pressure events (so far polyphonic pressure was not
568          supported at all, and channel pressure was rerouted as CC128 but not
569          used so far).
570        - Added initial support for real-time instrument scripts. The script VM
571          code is shared by all sampler engine implemementations, however only the
572          gig file format currently provides support for storing instrument scripts
573          (as LinuxSampler extension to the original GigaStudio 4 format).
574    
575      * Gigasampler format engine:
576        - implemented the "round robin keyboard" dimension
577        - fixed round robin and random dimensions for cases when number of
578          dimension zones is not a power of two

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

612        - added support for amp_veltrack and amp_velcurve_N
613        - fine-tuned the default velocity curve
614        - added support for transpose
615        - fixed crash when using sw_down/up
616        - improved logic for sw_lokey/hikey/up/down/last
617        - added more v1 aliases to parser
618        - reduced memory usage for sfz data
619        - RT-safeness: avoid malloc in audio thread
620        - fixed a bug that could cause voice stealing to fail
621        - optimized sample lookup
622        - improved support for exclusive groups (group, off_by and

629          not set in sfz file
630        - implemeted filters. Filter types: lowpass, bandpass, bandreject

757        - bugfix: line numbers in error messages were wrong after "#include"
758        - added support for float and 32 bit sample files
759    
760      * SoundFont format engine:

770        - AU bugfix: failed to destroy its audio/MIDI devices
771        - Listen to all interfaces on Mac OS X (INADDR_ANY)
772        - VST bugfix: If the host called resume() before and after
773          changing sample rate or block size, the number of channels was
774          incorrectly set to two. This caused silence in Cubase 5.
775        - save engine type (gig, sfz or sf2) in plugin state
776        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
777          64 bit Windows
778        - AU: changed number of output channels from one stereo to 16
779          stereo

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

808          informations like the EngineChannel for which the instrument editor was
809          spawned for. This allows the instrument editors to interact more actively
810          with the sampler.
811    
812      * MIDI driver:
813        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
814          the ALSA sequencer client name

816          there is no reason for this limit
817        - MME: fixed memory handling bug found with cppcheck
818        - MME: removed compiler warning
819        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
820          which allows to retrieve the list of CoreMIDI clients / ports and to connect
821          to them a la JACK, via the usual sampler APIs
822        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
823          the driver will automatically connect to other CoreMIDI clients' ports

828          virtual keyboards in frontends / instrument editors being stuck.
829        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
830        - Implemented missing handling of MIDI "running status".
831        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
832        - MME bugfix: driver wasn't closed properly
833        - CoreMIDI: automatically connect to all input sources by default (driver
834          parameter "AUTO_BIND").
835        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
836        - CoreMIDI: fixed minor memory leak
837    
838      * audio driver:
839        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
840        - JACK audio: react on sample rate changes.
841        - JACK audio: react on buffer size changes.

843          RT context.
844        - ASIO driver: removed compiler warnings
845        - CoreAudio: fixed minor error handling bug
846        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

898        - Added support for moving cursor left/right with arrow keys.
899        - Added support for built-in LSCP reference documentation, which will
900          automatically show the relevant LSCP reference section on screen as soon
901          as one specific LSCP command was detected while typing on the command

963        - bugfix: calling SET VOICES (which Fantasia does on start and
964          refresh) could cause instruments to be unloaded
965        - Mac OS X: fixed name collision of enum in EffectControl and
966          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
967        - Mac OS X: fixed hanging threads

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

991          introduced in previous fix)
992        - fixed crash when a channel received a program change while
993          playing a note in a key group
994        - fixed erroneous error message piping in VoiceBase.h
995          (labelled "Disk stream not available in time")
996        - Update effects on sample rate & period size changes (to avoid
997          crashes and noise on such transitions).
998        - ignore missing LADSPA paths without ignoring valid LADSPA paths
999          (fixes #208)
1000        - Fixed bug in LSCP grammar definition which caused a statement like
1001          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1002          practically irrelevant, however it caused problems with the new LSCP
1003          shell's auto completion feature).
1004        - Fixed MIDI program change messages being ignored if quickly executed
1005          after each other (fixes #231).
