# 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++11 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++11 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++11).
10    
11      * Real-time instrument scripts:
12        - Added method ScriptVM::setExitResultEnabled() which allows to
13          explicitly enable the built-in exit() function to optionally accept
14          one function argument; the value of the passed exit() function
15          argument will then become available by calling
16          VMExecContext::exitResult() after script execution.
17        - 64 bit support for NKSP integer scripts variables (declare $foo).
18        - Variable names, function names and preprocessor condition names must start
19          with a regular character (a-z or A-Z); starting them with a digit or
20          underscore is not allowed.
21        - NKSP parser fix: equal comparison operator "=" and not equal comparison
22          operator "#" must only accept integer operands.
23        - NKSP language: Implemented support for standard units like Hertz, seconds,
24          Bel including support for metric unit prefixes; so one can now e.g.
25          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
26          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
27          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
28        - NKSP language: Introduced "final" operator "!" which is specifically
29          intended for synthesis parameter values to denote that the synthesis
30          parameter value is intended to be the "final" value for that synthesis
31          parameter that should explicitly be used by the engine and thus causing
32          the sampler engine to ignore all other modulation sources for the same
33          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
34          variable or formula with this new "!" operator the expression is marked as
35          being "final".
36        - NKSP script editor API: Added support for detecting standard unit tokens
37          and their potential metric prefix token.
38        - NKSP language: Added support for NKSP real number literals and
39          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
40        - NKSP language: Added support for NKSP real number (floating point) script
41          variables (declare ~foo).
42        - NKSP language: Added support for NKSP real number (floating point) array
43          script variables (declare ?foo[]).
44        - Built-in script function "message()" accepts now real number argument as
45          well.
46        - Added built-in script function "real_to_int()" and its short hand form
47          "int()" for casting from real number to integer in NKSP scripts.
48        - Added built-in script function "int_to_real()" and its short hand form
49          "real()" for casting from integer to real number in NKSP scripts.
50    
51      * test cases:
52        - Fixed compiler errors in test cases.
53        - Updated README for how to compile & run test cases.
54        - Updated test case
55          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
56          expected behaviour of the Mutex class implementation (recursive
57          mutex type).
58        - Added test cases for NKSP core language aspects and core built-in
59          functions.
60        - Fixed thread tests segfaulting on Linux.
61    
62    Version 2.1.1 (27 Jul 2019)
63    
64      * Real-time instrument scripts:
65        - Fixed behavior of built-in NKSP functions change_sustain(),
66          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
67          and change_cutoff_release().
68    
69      * general changes:
70        - Only play release trigger samples on sustain pedal up if this behaviour
71          was explicitly requested by the instrument (otherwise only on note-off).
72        - Fixed compiler warnings.
73        - Fixed compilation error when cross-compiling to Mac.
74        - FX Sends: Provide more useful error messages on routing problems
75          (see bug #169).
76        - LSCP doc: Be more clear describing the two distinct approaches
77          of using external vs. internal effects (see bug #169).
78        - "optional" class: Fixed comparison operators.
79    
80      * Gigasampler/GigaStudio format engine:
81        - Format extension: If requested by instrument then don't play release
82          trigger sample on note-off events.
83    
84      * SFZ format engine:
85        - Fixed memory leak when releasing samples
86          (fixes bug #307, patch by Jacek Roszkowski)
87        - Fixed potential crash when a sample is shared by more than one region
88          (fixes bug #308, patch by Jacek Roszkowski).
89        - Opcode 'sample': Added support for built-in sample '*silence'
90          (fixes bug #310, patch by Jacek Roszkowski).
91    
92    Version 2.1.0 (25 Nov 2017)
93    
94      * SFZ format engine:
95        - added support for <global>, <master> and #define (patch by Alby M)
96        - Removed code duplication in SFZ file loading code.
97        - Added support for sfz extension opcode 'script' which may be used to
98          load real-time instrument script file (NKSP script language).
99        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
100        - Fixed unintended volume fade-in of voices under certain conditions.
101        - sfz parser: allow missing space between header and opcode
102    
103      * Gigasampler/GigaStudio format engine:
104        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
105          cutoff settings.
106        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
107          all if an up-pitch of more than 40 semi tones was requested (I don't
108          think there is any stock gig sound that requires this behavior to
109          resemble its original sound).
110        - Added support for controlling whether the individual EGADSR stages may
111          be aborted (as LinuxSampler extension to the original GigaStudio 4
112          format).
113    
114      * general changes:
115        - fixed printf type errors (mostly in debug messages)
116        - use unique_ptr instead of auto_ptr when building with C++11
117        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
118          allowing to sort data efficiently in real-time safe manner.
119        - RTList class: added methods for moving/inserting elements to arbitrary
120          position within a list.
121        - RTList class: added method fromPtr() for creating an Iterator object from
122          a raw element pointer.
123        - Attempt to partly fix resetting engine channels vs. resetting engine, an
124          overall cleanup of the Reset*(), ConnectAudioDevice(),
125          DisconnectAudioDevice() API methods would still be desirable though,
126          because the current situation is still inconsistent and error prone.
127        - Active voices are now internally grouped to "Note" objects, instead of
128          being directly assigned to a keyboard key. This allows more fine graded
129          processing of voices, which is i.e. required for certain instrument
130          script features.
131        - Fix: Release trigger voices were not spawned on sustain pedal up
132          (CC #64) events.
133        - Fix: Release trigger voices can now also distinguish correctly between
134          note-off and sustain pedal up events.
135        - All engines: Increased ramp speed of volume smoother and pan smoother
136          (while slow rate of crossfade smoother is preserved) to allow quick
137          volume and pan changes by instrument scripts for instance.
138        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
139          properly and thus were ignored for certain uses.
140        - Added new C++ API method
141          VirtualMidiDevice::SendChannelPressureToSampler().
142        - windows, 32-bit: fixed potential crashes by making sure the stack in
143          sub threads is 16-byte aligned
144        - fixed numerous compiler warnings
145        - Fixed invalid (note-on) event ID being assigned to new Note objects.
146        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
147          fixes potential undefined behavior.
148        - Fixed Note object leak when triggering notes on keys which did not
149          have a valid sample mapped (fixes bug #252).
150        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
151        - linuxsampler binary fix: option --create-instruments-db ignored
152          subsequent optional argument due to glibc's implementation oddity
153          which expects a "=" sign, but no space between them.
154    
155      * packaging changes:
156        - removed unnecessary dependency to libuuid
157          (originated by libgig's usage of it)
158        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
159          auto detect whether it (sh/c)ould output its messages in color.
160        - Debian: Fixed packaging error about invalid "Source-Version"
161          substitution variable.
162        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
163        - Debian: Added build dependency to libsqlite3-dev for building
164          linuxsampler with instruments DB support.
165    
166      * Real-time instrument scripts:
167        - Implemented scheduler for delayed MIDI events and for suspended scripts.
168        - Built-in script function "wait()": implemented support for function's
169          "duration-us" argument, thus scripts using this function are now
170          correctly resumed after the requested amount of microseconds.
171        - Built-in script function "play_note()": implemented support for
172          function's "duration-us" argument, thus notes triggered with this
173          argument are now correctly released after the requested amount of
174          microseconds.
175        - Fix: script events were not cleared when engine channel was reset,
176          potentially causing undefined behavior.
177        - Fixed crash which happened when trying to reference an undeclared
178          variable.
179        - Built-in script function "play_note()": Added support for passing
180          special value -1 for "duration-us" argument, which will cause the
181          triggered note to be released once the original note was released.
182        - Instrument script classes now exported with the liblinuxsampler C++ API.
183        - Added new API method ScriptVM::syntaxHighlighting() which provides
184          a convenient syntax highlighting backend for external instrument
185          script editor applications.
186        - Added new C++ API class "ScriptVMFactory".
187        - Extended parser issues to provide not only first line and first
188          column, but also last line and last column of issue (thus marking
189          the precise span of the issue within the source code).
190        - Reload script automatically after being modified by an instrument
191          editor.
192        - NKSP language grammar correction: allow empty event handler bodies
193          like "on note end on".
194        - Implemented built-in script function "change_vol()".
195        - Implemented built-in script function "change_tune()".
196        - Implemented built-in script function "change_pan()".
197        - Implemented built-in script function "change_cutoff()".
198        - Implemented built-in script function "change_reso()".
199        - Implemented built-in script function "event_status()".
200        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
201          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
202          "event_status()" function.
203        - NKSP language: Added support for bitwise operators ".or.", ".and."
204          and ".not.".
205        - NKSP language scanner: Fixed IDs matching to require at least one
206          character (i.e. when matching function names or variable names).
207        - NKSP language scanner: disabled unusued rules.
208        - Fixed behavior of play_note() and note_off() functions which must
209          be distinguished engine internally from "real" MIDI note on/off
210          events in order to avoid misbehaviors like hanging notes.
211        - Implemented built-in script variable "$KSP_TIMER".
212        - Implemented built-in script variable "$NKSP_REAL_TIMER".
213        - Implemented built-in script variable "$NKSP_PERF_TIMER".
214        - Implemented built-in script variable "$ENGINE_UPTIME".
215        - Implemented built-in script function "inc()".
216        - Implemented built-in script function "dec()".
217        - NKSP language fix: division expressions were evaluated too often.
218        - NKSP language fix: string concatenation operator was right
219          associative instead of left (to right).
220        - NKSP language correction: allow empty statements in entire language
221          (i.e. "if end if").
222        - Implemented built-in script function "stop_wait()".
223        - Implemented built-in script variable "$NI_CALLBACK_ID".
224        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
225        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
226        - Added support for read-only built-in variables (respectively
227          handled by the script parser).
228        - Added built-in script constant "$NI_CB_TYPE_INIT".
229        - Added built-in script constant "$NI_CB_TYPE_NOTE".
230        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
231        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
232        - NKSP Language: Added support for user defined script functions.
233        - Implemented built-in script function "change_attack()".
234        - Implemented built-in script function "change_decay()".
235        - Implemented built-in script function "change_release()".
236        - Fixed all change_*() built-in script functions to apply their
237          synthesis parameter changes immediately in case the respective note
238          was triggered at the same time, instead of scheduling the parameter
239          change, especially because it would cause some parameter types's
240          changes either to be ramped (i.e. change_vol()) or other types even
241          to have not effect at all (i.e. change_attack()).
242        - Implemented built-in script function "sh_left()".
243        - Implemented built-in script function "sh_right()".
244        - Implemented built-in script function "min()".
245        - Implemented built-in script function "max()".
246        - NKSP Fix: "init" event handler was not always executed when a script
247          was loaded.
248        - NKSP built-in wait() script function: abort script execution if
249          a negative or zero wait time was passed as argument (since this is
250          a common indication of a bug either of the script or even of the
251          engine, which could lead to RT instability or even worse).
252        - ScriptVM: Implemented automatic suspension of RT safety
253          threatening scripts.
254        - Provide more user friendly error messages on syntax errors.
255        - Fixed NKSP parser warning "Not a statement" when assigning an
256          initializer list to an array variable.
257        - Implemented built-in script array variable "%ALL_EVENTS".
258        - Implemented built-in script function "in_range()".
259        - Implemented built-in script function "change_amp_lfo_depth()".
260        - Implemented built-in script function "change_amp_lfo_freq()".
261        - Implemented built-in script function "change_pitch_lfo_depth()".
262        - Implemented built-in script function "change_pitch_lfo_freq()".
263        - Implemented built-in script function "change_vol_time()".
264        - Implemented built-in script function "change_tune_time()".
265        - Implemented built-in script function "fade_in()".
266        - Implemented built-in script function "fade_out()".
267        - Fixed acceptance of wrong data type of parameters passed to built-in
268          script functions "change_vol()", "change_tune()", "change_pan()",
269          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
270          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
271          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
272        - Added built-in script function "get_event_par()" and implemented some
273          of its possible parameter selections.
274        - Added built-in script function "set_event_par()" and implemented some
275          of its possible parameter selections.
276        - Fixed a bunch of scheduler time related bugs.
277        - Fixed polyphonic variables not being reset to zero after usage.
278        - Built-in "ignore_event()" function: argument is now optional, like with
279          built-in function "ignore_controller()".
280        - Implemented built-in script function "change_velo()".
281        - Implemented built-in script function "change_note()".
282        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
283          intuitive behavior if used in combination with "change_vol_time()" or
284          "change_tune_time()" respectively: now tuning/volume changes are only
285          assigned (without delay) immediately to a new note if the respective
286          timing function has not been called before, otherwise the volume/tuning
287          changes are automatically faded (before, only the event's time stamp was
288          relevant).
289         - Implemented built-in script function "array_equal()".
290         - Implemented built-in script function "search()".
291         - Implemented built-in script function "sort()".
292         - NKSP Fix: Never suspend "init" event handlers.
293         - Implemented built-in script function "same_region()" (currently only
294           available for gig format engine).
295         - Added built-in script constant "$NKSP_LINEAR".
296         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
297         - Implemented built-in script function "change_vol_curve()".
298         - Implemented built-in script function "change_tune_curve()".
299         - built-in "play_note()" function now supports a sample playback start
300           offset with argument 3, where special value -1 means to use the regular
301           sample offset as defined by the instrument file.
302         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
303         - Built-in variable $EVENT_NOTE is now a read-only variable.
304         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
305         - built-in "play_note()" function now accepts -2 for its fourth argument
306           (note duration) which means the life time of the note shall be sticked
307           to the requested note number of argument 1.
308         - Fix: built-in "play_note()" function now returns 0 as result value if
309           -1 was passed for its fourth argument (note duration) and the respective
310           parent note is already gone.
311        - Implemented built-in script function "change_play_pos()".
312        - NKSP language: Added support for user declared const array variables.
313        - NKSP language: Raise parser warning if array variable is accessed with
314          an index that exceeds the array's size.
315        - NKSP language fix: Unknown characters were not handled correctly.
316        - NKSP language: Added support for "synchronized .. end synchronized"
317          code blocks.
318        - Implemented built-in script function "abort()" which allows to abort
319          another script handler by passing its callback ID.
320        - Fixed potential memory access bug and potential undefined behavior of
321          "init" event handlers.
322        - Print a time stamp along to each call of built-in function "message()".
323        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
324          to retrieve all code blocks filtered out by the preprocessor.
325        - Added built-in script function "fork()".
326        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
327        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
328        - Fixed potential crash when accessing dynamic built-in array variables.
329        - Added built-in script function "callback_status()".
330        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
331        - Added built-in constant $CALLBACK_STATUS_QUEUE.
332        - Added built-in constant $CALLBACK_STATUS_RUNNING.
333        - Removed max. value limitation of built-in functions "change_attack()",
334          "change_decay()" and "change_release()" to i.e. allow passing 2000000
335          for doubling the respective time.
336        - NKSP script editor syntax highlighting API: Fixed app termination due
337          to a lexer start condition stack underrun.
338        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
339          USE_CODE_IF_NOT() preprocessor statements.
340        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
341          can be set to disable all subsequent built-in "message()" function calls
342          on preprocessor level.
343        - Implemented built-in script function "change_sustain()".
344        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
345          to avoid the editor app to crash on ill-formed text input.
346        - Added built-in script function "change_pan_time()".
347        - Added built-in script function "change_pan_curve()".
348        - Added built-in script function "change_cutoff_attack()".
349        - Added built-in script function "change_cutoff_decay()".
350        - Added built-in script function "change_cutoff_sustain()".
351        - Added built-in script function "change_cutoff_release()".
352        - Added built-in script function "change_cutoff_lfo_depth()".
353        - Added built-in script function "change_cutoff_lfo_freq()".
354    
355      * Instruments DB:
356        - Fixed memory access bug of general DB access code which lead to
357          undefined behavior.
358        - Cleanup of instruments DB file creation and opening code.
359        - The instrument DB path of linuxsampler's --create-instruments-db argument
360          is now optional, if it is missing, then a default location is used.
361        - Added support for scanning SFZ (.sfz) files.
362        - Added support for scanning Sound Font (.sf2) files.
363        - Fixed undefined DB transaction behavior.
364    
365    Version 2.0.0 (15 July 2015)
366

403          in order to get rid of warnings from automake 1.14
404    
405      * general changes:
406        - Refactoring: moved the independent code from
407          the Gigasampler format engine to base classes
408        - command line option '--profile' is currently disabled, since the
409          respective profiling code is currently broken
410        - Introduced support for optional environment variable
411          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
412          where the sampler shall look for instrument editor plugins
413          (patch by Luis Garrido, slightly modified).
414        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
415        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
416        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
417          note (in this implementation of the sampler its simply hard routed to
418          the 1st effect send of the sampler channel, no matter what the actual
419          effect type is)
420        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
421          note (in this implementation of the sampler its simply hard routed to
422          the 2nd effect send of the sampler channel, no matter what the actual
423          effect type is)
424        - implemented support for internal LADSPA effects
425        - raised limit of program change queue from 100 to 512
426          (as suggested by Alex Stone)
427        - implemented sine LFO, pulse LFO and saw LFO
428        - experimental support for per voice equalization
429        - added command line option --exec-after-init
430        - Introduced new C++ API method:
431          EngineChannel::InstrumentFileName(int index)
432          allowing to retrieve the whole list of files used for the loaded
433          instrument on an engine channel (a.k.a. part). Some GigaStudio
434          instruments for example are splitted over several files like
435          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
436        - Added new C++ API method Sampler::GetGlobalMaxVoices().
437        - Added new C++ API method Sampler::GetGlobalMaxStreams().
438        - Added new C++ API method Sampler::SetGlobalMaxVoices().
439        - Added new C++ API method Sampler::SetGlobalMaxStreams().
440        - Various "const" and "restrict" optimizations.
441        - all engines: add pan CC value to instrument pan parameter before
442          applying panning, instead of using two separate pan functions in
443          series (#182)
444        - added a lock guard class for exception safe mutex handling and
445          used it everywhere appropriate
446        - Immediately apply scale tuning changes to active voices.
447        - Exposed scale tuning to C++ API (along to the already existing standard
448          SysEx way).
449        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
450          and broken for ppc64. (Seq_cst loads and stores are actually not
451          used in LS, so the bug wasn't noticable.)
452        - lsatomic.h: added ARMv7 support
453        - Added support for multiple MIDI input ports per sampler channel (and
454          added various new C++ methods for this new feature / design change, old
455          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
456          as deprecated but are still there and should provide full behavior
457          backward compatibility).
458        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
459          unsafe and caused compilation error with clang 2.x).
460        - Bugfix: only process the latest MIDI program change event.
461        - Introducing the LSCP shell, which provides convenient control of the
462          sampler from the command line by providing LSCP aware features.
463        - VirtualMidiDevice: Added support for program change.
464        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
465        - VirtualMidiDevice: Added support for pitch bend.
466        - Aftertouch: extended API to explicitly handle channel pressure and
467          polyphonic key pressure events (so far polyphonic pressure was not
468          supported at all, and channel pressure was rerouted as CC128 but not
469          used so far).
470        - Added initial support for real-time instrument scripts. The script VM
471          code is shared by all sampler engine implemementations, however only the
472          gig file format currently provides support for storing instrument scripts
473          (as LinuxSampler extension to the original GigaStudio 4 format).
474    
475      * Gigasampler format engine:
476        - implemented the "round robin keyboard" dimension
477        - fixed round robin and random dimensions for cases when number of
478          dimension zones is not a power of two
479        - made round robin use a counter for each region instead of each
480          key
481        - bugfix: pitch LFO controller "internal+aftertouch" was broken
482        - bugfix: filter keyboard tracking was broken
483        - filter performance fix (an unnecessary copy was made of the
484          filter parameters in each sub fragment)
485        - handle special case when pan parameter in gig file has max or
486          min value
487        - Exclusive Groups: don't ever stop voices of the same note,
488          doesn't sound naturally with a drumkit
489        - fixed EG1 modulation when attack or release is zero
490        - Fixed support for 'aftertouch' attenuation controller.
491        - Fixed crash that happened with velocity split sounds under certain
492          conditions (see also previous commit on libgig).
493        - fixed behaviour of filter LFO
494    
495      * SFZ format engine:
496        - Initial implementation (not usable yet)

498        - added a fine-tuned v1 envelope generator instead of using the
499          one from the gig engine

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

504        - fixed error when unloading instrument with same sample used by
505          multiple regions

513        - fine-tuned the default velocity curve
514        - added support for transpose
515        - fixed crash when using sw_down/up
516        - improved logic for sw_lokey/hikey/up/down/last
517        - added more v1 aliases to parser
518        - reduced memory usage for sfz data
519        - RT-safeness: avoid malloc in audio thread

525        - added support for loop_mode=one_shot
526        - fixed playback of 16 bit wav files on big endian CPUs
527        - added support for Ogg Vorbis sample files
528        - use loop markers from sample file if loop_start and loop_end are
529          not set in sfz file
530        - implemeted filters. Filter types: lowpass, bandpass, bandreject

657        - bugfix: line numbers in error messages were wrong after "#include"
658        - added support for float and 32 bit sample files
659    
660      * SoundFont format engine:

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

689        - thread safety fixes for the instrument loading thread
690        - LV2: use the new lv2 package if present
691        - VST: try to open Fantasia automatically on Linux and Mac too (on
692          Linux, the Fantasia jar should be placed in <prefix>/share/java)
693        - VST: fixed crashes on Linux Ardour and EnergyXT
694        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
695          port and audio channel routing for DSSI plugins are now visible.
696        - LV2: use urid and atom extensions instead of deprecated uri-map
697          and event
698        - LV2: lv2 package 1.0 is now required to build the LV2 plugin

707        - Changed instrument editor plugin interface, providing additional
708          informations like the EngineChannel for which the instrument editor was
709          spawned for. This allows the instrument editors to interact more actively
710          with the sampler.
711    
712      * MIDI driver:
713        - ALSA MIDI driver supports now "NAME" device parameter, for overriding

718        - MME: removed compiler warning
719        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",

721          to them a la JACK, via the usual sampler APIs
722        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
723          the driver will automatically connect to other CoreMIDI clients' ports
724          (e.g. external MIDI devices being attached to the Mac)
725        - added support for MIDI note on velocity filter
726        - CoreMIDI: fixed memory deallocation error
727        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
728          virtual keyboards in frontends / instrument editors being stuck.
729        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
730        - Implemented missing handling of MIDI "running status".

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

743          RT context.
744        - ASIO driver: removed compiler warnings
745        - CoreAudio: fixed minor error handling bug
746        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
747        - JACK audio: return the JACK server's current sample rate as default value
748          for audio device parameter "SAMPLERATE" (fixes #166).
749

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

893          playing a note in a key group
894        - fixed erroneous error message piping in VoiceBase.h
895          (labelled "Disk stream not available in time")
896        - Update effects on sample rate & period size changes (to avoid
897          crashes and noise on such transitions).
898        - ignore missing LADSPA paths without ignoring valid LADSPA paths
899          (fixes #208)
900        - Fixed bug in LSCP grammar definition which caused a statement like
901          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
902          practically irrelevant, however it caused problems with the new LSCP
903          shell's auto completion feature).
904        - Fixed MIDI program change messages being ignored if quickly executed
905          after each other (fixes #231).
