# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9        - Fixed unintended volume fade-in of voices under certain conditions.
10        - sfz parser: allow missing space between header and opcode
11    
12      * Gigasampler/GigaStudio format engine:
13        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14          cutoff settings.
15        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16          all if an up-pitch of more than 40 semi tones was requested (I don't
17          think there is any stock gig sound that requires this behavior to
18          resemble its original sound).
19    
20      * general changes:
21        - fixed printf type errors (mostly in debug messages)
22        - use unique_ptr instead of auto_ptr when building with C++11
23        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
24          allowing to sort data efficiently in real-time safe manner.
25        - RTList class: added methods for moving/inserting elements to arbitrary
26          position within a list.
27        - RTList class: added method fromPtr() for creating an Iterator object from
28          a raw element pointer.
29        - Attempt to partly fix resetting engine channels vs. resetting engine, an
30          overall cleanup of the Reset*(), ConnectAudioDevice(),
31          DisconnectAudioDevice() API methods would still be desirable though,
32          because the current situation is still inconsistent and error prone.
33        - Active voices are now internally grouped to "Note" objects, instead of
34          being directly assigned to a keyboard key. This allows more fine graded
35          processing of voices, which is i.e. required for certain instrument
36          script features.
37        - Fix: Release trigger voices were not spawned on sustain pedal up
38          (CC #64) events.
39        - Fix: Release trigger voices can now also distinguish correctly between
40          note-off and sustain pedal up events.
41        - All engines: Increased ramp speed of volume smoother and pan smoother
42          (while slow rate of crossfade smoother is preserved) to allow quick
43          volume and pan changes by instrument scripts for instance.
44        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
45          properly and thus were ignored for certain uses.
46        - Added new C++ API method
47          VirtualMidiDevice::SendChannelPressureToSampler().
48        - windows, 32-bit: fixed potential crashes by making sure the stack in
49          sub threads is 16-byte aligned
50        - fixed numerous compiler warnings
51        - Fixed invalid (note-on) event ID being assigned to new Note objects.
52        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
53          fixes potential undefined behavior.
54        - Fixed Note object leak when triggering notes on keys which did not
55          have a valid sample mapped (fixes bug #252).
56        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
57    
58      * packaging changes:
59        - removed unnecessary dependency to libuuid
60          (originated by libgig's usage of it)
61        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
62          auto detect whether it (sh/c)ould output its messages in color.
63    
64      * Real-time instrument scripts:
65        - Implemented scheduler for delayed MIDI events and for suspended scripts.
66        - Built-in script function "wait()": implemented support for function's
67          "duration-us" argument, thus scripts using this function are now
68          correctly resumed after the requested amount of microseconds.
69        - Built-in script function "play_note()": implemented support for
70          function's "duration-us" argument, thus notes triggered with this
71          argument are now correctly released after the requested amount of
72          microseconds.
73        - Fix: script events were not cleared when engine channel was reset,
74          potentially causing undefined behavior.
75        - Fixed crash which happened when trying to reference an undeclared
76          variable.
77        - Built-in script function "play_note()": Added support for passing
78          special value -1 for "duration-us" argument, which will cause the
79          triggered note to be released once the original note was released.
80        - Instrument script classes now exported with the liblinuxsampler C++ API.
81        - Added new API method ScriptVM::syntaxHighlighting() which provides
82          a convenient syntax highlighting backend for external instrument
83          script editor applications.
84        - Added new C++ API class "ScriptVMFactory".
85        - Extended parser issues to provide not only first line and first
86          column, but also last line and last column of issue (thus marking
87          the precise span of the issue within the source code).
88        - Reload script automatically after being modified by an instrument
89          editor.
90        - NKSP language grammar correction: allow empty event handler bodies
91          like "on note end on".
92        - Implemented built-in script function "change_vol()".
93        - Implemented built-in script function "change_tune()".
94        - Implemented built-in script function "change_pan()".
95        - Implemented built-in script function "change_cutoff()".
96        - Implemented built-in script function "change_reso()".
97        - Implemented built-in script function "event_status()".
98        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
99          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
100          "event_status()" function.
101        - NKSP language: Added support for bitwise operators ".or.", ".and."
102          and ".not.".
103        - NKSP language scanner: Fixed IDs matching to require at least one
104          character (i.e. when matching function names or variable names).
105        - NKSP language scanner: disabled unusued rules.
106        - Fixed behavior of play_note() and note_off() functions which must
107          be distinguished engine internally from "real" MIDI note on/off
108          events in order to avoid misbehaviors like hanging notes.
109        - Implemented built-in script variable "$KSP_TIMER".
110        - Implemented built-in script variable "$NKSP_REAL_TIMER".
111        - Implemented built-in script variable "$NKSP_PERF_TIMER".
112        - Implemented built-in script variable "$ENGINE_UPTIME".
113        - Implemented built-in script function "inc()".
114        - Implemented built-in script function "dec()".
115        - NKSP language fix: division expressions were evaluated too often.
116        - NKSP language fix: string concatenation operator was right
117          associative instead of left (to right).
118        - NKSP language correction: allow empty statements in entire language
119          (i.e. "if end if").
120        - Implemented built-in script function "stop_wait()".
121        - Implemented built-in script variable "$NI_CALLBACK_ID".
122        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
123        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
124        - Added support for read-only built-in variables (respectively
125          handled by the script parser).
126        - Added built-in script constant "$NI_CB_TYPE_INIT".
127        - Added built-in script constant "$NI_CB_TYPE_NOTE".
128        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
129        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
130        - NKSP Language: Added support for user defined script functions.
131        - Implemented built-in script function "change_attack()".
132        - Implemented built-in script function "change_decay()".
133        - Implemented built-in script function "change_release()".
134        - Fixed all change_*() built-in script functions to apply their
135          synthesis parameter changes immediately in case the respective note
136          was triggered at the same time, instead of scheduling the parameter
137          change, especially because it would cause some parameter types's
138          changes either to be ramped (i.e. change_vol()) or other types even
139          to have not effect at all (i.e. change_attack()).
140        - Implemented built-in script function "sh_left()".
141        - Implemented built-in script function "sh_right()".
142        - Implemented built-in script function "min()".
143        - Implemented built-in script function "max()".
144        - NKSP Fix: "init" event handler was not always executed when a script
145          was loaded.
146        - NKSP built-in wait() script function: abort script execution if
147          a negative or zero wait time was passed as argument (since this is
148          a common indication of a bug either of the script or even of the
149          engine, which could lead to RT instability or even worse).
150        - ScriptVM: Implemented automatic suspension of RT safety
151          threatening scripts.
152        - Provide more user friendly error messages on syntax errors.
153        - Fixed NKSP parser warning "Not a statement" when assigning an
154          initializer list to an array variable.
155        - Implemented built-in script array variable "%ALL_EVENTS".
156        - Implemented built-in script function "in_range()".
157        - Implemented built-in script function "change_amp_lfo_depth()".
158        - Implemented built-in script function "change_amp_lfo_freq()".
159        - Implemented built-in script function "change_pitch_lfo_depth()".
160        - Implemented built-in script function "change_pitch_lfo_freq()".
161        - Implemented built-in script function "change_vol_time()".
162        - Implemented built-in script function "change_tune_time()".
163        - Implemented built-in script function "fade_in()".
164        - Implemented built-in script function "fade_out()".
165        - Fixed acceptance of wrong data type of parameters passed to built-in
166          script functions "change_vol()", "change_tune()", "change_pan()",
167          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
168          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
169          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
170        - Added built-in script function "get_event_par()" and implemented some
171          of its possible parameter selections.
172        - Added built-in script function "set_event_par()" and implemented some
173          of its possible parameter selections.
174        - Fixed a bunch of scheduler time related bugs.
175        - Fixed polyphonic variables not being reset to zero after usage.
176        - Built-in "ignore_event()" function: argument is now optional, like with
177          built-in function "ignore_controller()".
178        - Implemented built-in script function "change_velo()".
179        - Implemented built-in script function "change_note()".
180        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
181          intuitive behavior if used in combination with "change_vol_time()" or
182          "change_tune_time()" respectively: now tuning/volume changes are only
183          assigned (without delay) immediately to a new note if the respective
184          timing function has not been called before, otherwise the volume/tuning
185          changes are automatically faded (before, only the event's time stamp was
186          relevant).
187         - Implemented built-in script function "array_equal()".
188         - Implemented built-in script function "search()".
189         - Implemented built-in script function "sort()".
190         - NKSP Fix: Never suspend "init" event handlers.
191         - Implemented built-in script function "same_region()" (currently only
192           available for gig format engine).
193         - Added built-in script constant "$NKSP_LINEAR".
194         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
195         - Implemented built-in script function "change_vol_curve()".
196         - Implemented built-in script function "change_tune_curve()".
197         - built-in "play_note()" function now supports a sample playback start
198           offset with argument 3, where special value -1 means to use the regular
199           sample offset as defined by the instrument file.
200         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
201         - Built-in variable $EVENT_NOTE is now a read-only variable.
202         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
203         - built-in "play_note()" function now accepts -2 for its fourth argument
204           (note duration) which means the life time of the note shall be sticked
205           to the requested note number of argument 1.
206         - Fix: built-in "play_note()" function now returns 0 as result value if
207           -1 was passed for its fourth argument (note duration) and the respective
208           parent note is already gone.
209        - Implemented built-in script function "change_play_pos()".
210        - NKSP language: Added support for user declared const array variables.
211        - NKSP language: Raise parser warning if array variable is accessed with
212          an index that exceeds the array's size.
213        - NKSP language fix: Unknown characters were not handled correctly.
214        - NKSP language: Added support for "synchronized .. end synchronized"
215          code blocks.
216        - Implemented built-in script function "abort()" which allows to abort
217          another script handler by passing its callback ID.
218        - Fixed potential memory access bug and potential undefined behavior of
219          "init" event handlers.
220        - Print a time stamp along to each call of built-in function "message()".
221        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
222          to retrieve all code blocks filtered out by the preprocessor.
223        - Added built-in script function "fork()".
224        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
225        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
226        - Fixed potential crash when accessing dynamic built-in array variables.
227        - Added built-in script function "callback_status()".
228        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
229        - Added built-in constant $CALLBACK_STATUS_QUEUE.
230        - Added built-in constant $CALLBACK_STATUS_RUNNING.
231        - Removed max. value limitation of built-in functions "change_attack()",
232          "change_decay()" and "change_release()" to i.e. allow passing 2000000
233          for doubling the respective time.
234    
235      * Instruments DB:
236        - Fixed memory access bug of general DB access code which lead to
237          undefined behavior.
238        - Cleanup of instruments DB file creation and opening code.
239        - The instrument DB path of linuxsampler's --create-instruments-db argument
240          is now optional, if it is missing, then a default location is used.
241        - Added support for scanning SFZ (.sfz) files.
242        - Added support for scanning Sound Font (.sf2) files.
243        - Fixed undefined DB transaction behavior.
244    
245    Version 2.0.0 (15 July 2015)
246    
247      * packaging changes:
248        - fixed building with newer MinGW-w64
249        - Mac OS X: support the new dir for Core Audio SDK
250        - Mac OS X: fixed building outside source directory
251        - made sure all source files for hostplugins are included when
252          doing "make dist"
253        - removed empty directories left from the cvs to svn migration
254        - fixed compilation with gcc 4.6.1
255        - another "make dist" fix, for the LV2 plugin
256        - made --enable-pthread-testcancel default on Mac OS X
257        - minor Makefile fix for building lscpparser when build and source
258          directories are separate
259        - Mac OS X: made it possible to specify plugin installation dir to
260          configure
261        - Mac OS X: Makefile fix for the install-strip target
262        - fixed compilation with gcc 4.7
263        - fixed configure script error with old autoconf versions
264        - lsatomic.h: use gcc provided atomic functions if building with
265          gcc 4.7 and C++11
266        - modernized configure script
267        - fixed linkage error when building with
268          LDFLAGS="-Wl,--no-undefined" (#190)
269        - fixed compilation with Clang 3.2
270        - removed usage of deprecated Automake variable INCLUDES
271        - fixed building with C++11

273        - build fix: libsndfile compiler flags were missing in some
274          makefiles
275        - fix for building with bison 3.0 (#202)
276        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
277          on the process's main thread
278        - fixed build error on newer MinGW
279        - support building with older jack versions
280        - support building with spaces in vst sdk path
281        - enabled automake 'subdir-objects' option and moved external
282          source references (vst, au, asio) from makefiles to cpp files,
283          in order to get rid of warnings from automake 1.14
284    
285      * general changes:
286        - Refactoring: moved the independent code from
287          the Gigasampler format engine to base classes
288        - command line option '--profile' is currently disabled, since the
289          respective profiling code is currently broken
290        - Introduced support for optional environment variable
291          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
292          where the sampler shall look for instrument editor plugins
293          (patch by Luis Garrido, slightly modified).
294        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
295        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
296        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
297          note (in this implementation of the sampler its simply hard routed to
298          the 1st effect send of the sampler channel, no matter what the actual
299          effect type is)
300        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
301          note (in this implementation of the sampler its simply hard routed to
302          the 2nd effect send of the sampler channel, no matter what the actual
303          effect type is)
304        - implemented support for internal LADSPA effects
305        - raised limit of program change queue from 100 to 512
306          (as suggested by Alex Stone)
307        - implemented sine LFO, pulse LFO and saw LFO
308        - experimental support for per voice equalization
309        - added command line option --exec-after-init
310        - Introduced new C++ API method:
311          EngineChannel::InstrumentFileName(int index)
312          allowing to retrieve the whole list of files used for the loaded
313          instrument on an engine channel (a.k.a. part). Some GigaStudio
314          instruments for example are splitted over several files like
315          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
316        - Added new C++ API method Sampler::GetGlobalMaxVoices().
317        - Added new C++ API method Sampler::GetGlobalMaxStreams().
318        - Added new C++ API method Sampler::SetGlobalMaxVoices().
319        - Added new C++ API method Sampler::SetGlobalMaxStreams().
320        - Various "const" and "restrict" optimizations.
321        - all engines: add pan CC value to instrument pan parameter before
322          applying panning, instead of using two separate pan functions in
323          series (#182)
324        - added a lock guard class for exception safe mutex handling and
325          used it everywhere appropriate
326        - Immediately apply scale tuning changes to active voices.
327        - Exposed scale tuning to C++ API (along to the already existing standard
328          SysEx way).
329        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
330          and broken for ppc64. (Seq_cst loads and stores are actually not
331          used in LS, so the bug wasn't noticable.)
332        - lsatomic.h: added ARMv7 support
333        - Added support for multiple MIDI input ports per sampler channel (and
334          added various new C++ methods for this new feature / design change, old
335          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
336          as deprecated but are still there and should provide full behavior
337          backward compatibility).
338        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
339          unsafe and caused compilation error with clang 2.x).
340        - Bugfix: only process the latest MIDI program change event.
341        - Introducing the LSCP shell, which provides convenient control of the
342          sampler from the command line by providing LSCP aware features.
343        - VirtualMidiDevice: Added support for program change.
344        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
345        - VirtualMidiDevice: Added support for pitch bend.
346        - Aftertouch: extended API to explicitly handle channel pressure and
347          polyphonic key pressure events (so far polyphonic pressure was not
348          supported at all, and channel pressure was rerouted as CC128 but not
349          used so far).
350        - Added initial support for real-time instrument scripts. The script VM
351          code is shared by all sampler engine implemementations, however only the
352          gig file format currently provides support for storing instrument scripts
353          (as LinuxSampler extension to the original GigaStudio 4 format).
354    
355      * Gigasampler format engine:
356        - implemented the "round robin keyboard" dimension
357        - fixed round robin and random dimensions for cases when number of
358          dimension zones is not a power of two
359        - made round robin use a counter for each region instead of each
360          key
361        - bugfix: pitch LFO controller "internal+aftertouch" was broken
362        - bugfix: filter keyboard tracking was broken
363        - filter performance fix (an unnecessary copy was made of the
364          filter parameters in each sub fragment)
365        - handle special case when pan parameter in gig file has max or
366          min value
367        - Exclusive Groups: don't ever stop voices of the same note,
368          doesn't sound naturally with a drumkit

697        - Implemented built-in script int variable $EVENT_ID.
698        - Implemented built-in script function "ignore_event()"
699        - Implemented built-in script function "ignore_controller()" (may have one
700          or no argument).
701        - Implemented built-in script function "set_controller()".
702        - Added extended script VM for the Gigasampler/GigaStudio format sampler
703          engine, which extends the general instrument script VM with Giga format
704          specific variables and functions.
705        - Giga format scripts: added built-in script int constant variables
706          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

716        - Giga format scripts: Implemented built-in script function
717          "gig_set_dim_zone(event_id, dimension, zone)".
718        - Implemented built-in script int array variable %KEY_DOWN.
719        - Implemented built-in script function "abs()".
720        - Implemented built-in script function "random()".

725        - Implemented built-in script function "by_marks()".
726        - Added built-in script int const variables $MARK_1 to $MARK_28.
727        - Built-in script functions "ignore_event()", "note_off()" and
728          "gig_set_dim_zone()" now also accept an array of event IDs as argument
729          (i.e. return value of new script function "by_marks()").
730        - Pass/preserve polyphonic variable data from respective "note" event
731          handler to "release" event handler.
732        - Fixed crash when using built-in script function "by_marks()".
733    
734      * Bug fixes:
735        - Fixed crash which may occur when MIDI key + transpose is out of range
736        - minor valgrind fixes
737        - fixed crash which occurred when changing an already deployed sampler
738          channel to a different engine type
739        - fixed crash when deleting a sampler channel or changing engine
740          type while an instrument load was in progress
741        - bugfix: playing a note while changing the instrument could cause
742          a crash, or give "Handing back unknown region" error messages
743        - bugfix: calling SET VOICES (which Fantasia does on start and
744          refresh) could cause instruments to be unloaded
745        - Mac OS X: fixed name collision of enum in EffectControl and
746          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
747        - Mac OS X: fixed hanging threads
748        - Windows: disabled the previous thread fix on non-Mac systems, as
749          it caused hanging threads on Windows
750        - Fixed possible crashes due to corrupted MIDI/audio device list
751          after MIDI/audio device creation failure
752        - When creating MIDI instrument map entries with "PERSISTENT" type, the
753          instruments were uselessly precached with zero samples, however it still
754          took the full preloading time and on 1st program change the respective
755          instrument was completely reloaded again.
756        - fixed handling of rapid bank select and program change messages
757          sent to the same sampler channel (patch from the Open Octave
758          project, slightly adjusted)
759        - fixed crash when trying to create an effect instance with controls
760          which min and/or max values depend on the sample rate
761        - fixed bug #162
762        - bugfix: LADSPA_PATH was not evaluated correctly when containing
763          multiple paths (#165)
764        - thread safety fixes for the instrument loading thread
765        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
766          (#176)
767        - more thread safety fixes for the instrument loading thread
768        - sfz/sf2 engine: fixed crash when using small audio fragment size
769        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
770        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
771          introduced in previous fix)
772        - fixed crash when a channel received a program change while
773          playing a note in a key group
774        - fixed erroneous error message piping in VoiceBase.h
775          (labelled "Disk stream not available in time")
776        - Update effects on sample rate & period size changes (to avoid
777          crashes and noise on such transitions).
778        - ignore missing LADSPA paths without ignoring valid LADSPA paths
779          (fixes #208)
780        - Fixed bug in LSCP grammar definition which caused a statement like
781          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
782          practically irrelevant, however it caused problems with the new LSCP
783          shell's auto completion feature).
784        - Fixed MIDI program change messages being ignored if quickly executed
785          after each other (fixes #231).
786    
787    Version 1.0.0 (31 July 2009)
788    
789      * packaging changes:
790        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
791          causing e.g. the libgig test to fail when
792          "./configure --disable-jack-driver" was used
793          (patch by Alexis Ballier)
794        - fixed compilation with gcc 4.3
795        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
796        - fixed configure so it detects x86_64 (#107)
797        - fixes for building with newer MinGW versions
798        - fix for building with bison 2.4 (#111)
799        - fixed building with libgig installed in a non-standard directory
800        - minor fix in configure for mmsystem.h detection on MinGW
801        - Windows: look for editor plugins and Fantasia using base
802          directory of liblinuxsampler dll (look in the same directory and one
803          directory above)
804        - configure script fix: removed unconditional use of SSE
805        - fixed building with sqlite installed in a non-standard directory
806        - when cross-compiling, don't try to create instruments.db
807        - fix for new mingw-w64 version, which has usleep
808    
809      * general changes:
810        - bugfix: on some POSIX systems instrument editor plugins refused to
811          load as we used a non-portable Linux specific struct field
812          (fixes bug #70, patch by Ronald Baljeu)
813        - fixed endless loop which occured when loading an instrument editor
814          plugin DLL on Windows systems failed
815        - fixed memory leaks that occurred when liblinuxsampler was unloaded
816        - optimized the SynchronizedConfig class so it doesn't wait
817          unnecessarily long after an update
818        - added support for notifying instrument editors on note-on / note-off
819          events (e.g. to highlight the pressed keys on the virtual keyboard
820          of gigedit)
821        - added support for triggering notes by instrument editors (see above)
822        - be verbose on DLL load errors (on Linux)
823        - fixed di-harmonic triangle LFO implementation (this LFO implementation
824          is only used by very few systems, most pick the int math
825          implementation, which is usually faster)
826        - fixes for audio drivers with varying buffer sizes
827        - experimental support for running LinuxSampler as a DSSI, LV2 and
828          VST plugin
829        - notification events for stream/voice count statistics are now sent
830          only when there are actual changes
831        - added memory ordering constraints to improve stability on
832          multi-core and multi-cpu systems
833        - maximum voices and disk streams can now be altered at runtime
834        - fixed CPU feature detection on x86_64 (maybe fixes #108)
835        - automatic stacktrace mechanism is now turned off by default and can
836          be switched on by command line option "--stacktrace" (the automatic
837          stacktrace mechanism seems to be broken on most systems at the moment)
838        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
839          a pointer to the launched InstrumentEditor object
840        - added optional 3rd party user data parameter for following
841          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
842          InstrumentEditor::Launch(),
843          InstrumentManager::LaunchInstrumentEditor()
844        - theoretical fix: made SynchronizedConfig follow C++0x memory
845          model more strictly
846        - fixes for using large audio device buffers
847        - Windows: add the installation directory to the DLL search path
848          when loading an editor plugin (solves problems with VST and
849          gigedit on systems with other GTK versions installed)
850        - updated linuxsampler man page
851    
852      * audio driver:
853        - removed the nonsense audio channel constraint (which was hard coded to
854          max. 100 audio channels) for most audio drivers
855        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
856          opposed to the LSCP specs
857        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
858          reflected the wrong value
859        - fixed a memory management bug in ASIO driver
860        - Makefile fix: JACK_CFLAGS wasn't used
861        - JACK: use jack_client_open instead of the deprecated
862          jack_client_new
863        - added (experimental) CoreAudio driver
864        - applied old fixes to the ASIO driver that were included in the
865          previous binary release but accidentally never committed to CVS
866          (fixes #117)
867        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
868          win64)
869        - VST: added support for sample rate and buffer size changes
870        - VST: close editor (Fantasia) when the VST is removed
871        - VST: avoid opening Fantasia more than once for each VST instance
872        - VST: export main function as "main" on Linux too (fix for
873          energyXT)
874        - VST: changed number of output channels from one stereo to 16
875          stereo
876        - added channel routing, fxsends and midi maps to the settings
877          stored in the plugin state
878        - performance optimization of AudioChannel::MixTo() and
879          AudioChannel::CopyTo() methods using GCC vector exensions
880          (if available)
881        - ASIO fixes: avoid initializing the device twice, avoid throwing
882          exception when getting parameters from a disconnected device
883    
884      * MIDI driver:
885        - added JACK MIDI driver
886        - dispatch bank select as ordinary CC as well, the user might seriously
887          want to (mis)use it for some purpose ("fixed" in all current MIDI
888          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
889        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
890          CoreMidi or AU
891        - fixed mingw-w64 compilation error in MME driver
892        - made program change handling in MIDI thread real-time safe by
893          moving the logic to a non-RT thread
894        - fixed minor memory leak in ALSA driver
895    
896      * instruments database:
897        - avoid time consuming samples scanning when adding instruments
898          to the instruments database
899        - added support for handling lost files in the instruments database
900        - Implemented option for adding instruments in separate directories
901          in the instruments database
902          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
903        - work-around for missing fnmatch function on Windows to make
904          instrument database compilable
905        - added instrument database support on Windows
906          works with both standalone mode and VST plugin.
907          the instruments DB file is located in
908          %USERPROFILE%\.linuxsampler\instruments.db which allows different
909          databases for each windows user
910          if no DB is present it automatically creates the .linuxsampler subdir
911          and then creates an empty DB
912        - fixed recursive import, which was broken on Windows
913    
914      * Gigasampler format engine:
915        - fixed a memory leak that could happen when a channel was deleted
916          while notes were playing
917        - made it possible to load an instrument even if the audio thread
918          isn't running
919        - added partial support for the "Controller Triggered" MIDI rule,
920          enough for piano gigs with pedal noise samples
921        - minor fix: only mark FX sends as being modified if really the
922          respective FX send MIDI controller was used
923        - added support for GM global device volume SysEx message
924          (can be selected at compile time to either apply globally to the
925          whole sampler [default] or only to the sampler channels that are
926          connected to the respective MIDI input port the SysEx message arrived
927          on)
928        - bugfix: notes triggered at position 0 in the audio buffer were
929          sometimes wrongly killed in the same buffer, causing no sound to
930          be played
931        - added support for chromatic / drumkit mode Roland GS Sysex message
932          which is usally used to switch a part between chromatic sounds and
933          drumkit sounds (as opposed to their common default setting of MIDI
934          part 10 being a drumkit part and all other ones chromatic parts), in
935          LS however one can switch between the first 16 MIDI instrument maps
936          defined for the sampler
937        - made it possible to create multiple sample channels even if the
938          audio thread isn't running
939        - fixed crash when removing channel with active voices (#116)
940        - bugfix: on sample reference changes (instrument editor), only
941          un-cache the respective sample if it's really not used by any
942          sampler engine anymore
943        - re-cache samples in case they were changed by an instrument editor,
944          e.g. when a sample was added while playing (#82)
945        - fixed hanging notes which occured when note-off event had the exact
946          same time stamp as the voice's note-on event and occured both in the
947          same audio fragment cycle (fixes bug #112)
948        - added support for the "fine tune" and "pitch bend range"
949          instrument-level gig parameters
950        - fixed minor artifacts in pitch bend handling
951        - added support for GS Reset SysEx message
952        - allow gig files to use unlimited downward pitch shifting
953        - added a limit check for upward pitch shifting
954        - bugfix: sometimes, when playing a note twice fast, the second
955          note was silent
956        - fixed crash happening when a pitch bend event arrived at the
957          same time a new instrument was loading
958    
959      * LSCP server:
960        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
961          react on MIDI data arriving on certain sampler channels (so far only
962          Note-On and Note-Off events are sent via this LSCP event)
963        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
964          react on MIDI data arriving on certain MIDI input devices (so far only
965          Note-On and Note-Off events are sent via this LSCP event)
966        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
967          SET DB_INSTRUMENT FILE_PATH
968        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
969          frontends to send MIDI messages to specific sampler channel
970        - added two additional fields to GET FILE INSTRUMENT INFO command -
971          KEY_BINDINGS and KEYSWITCH_BINDINGS
972        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
973          was incorrect
974        - Optimized the retrieval of the MIDI instrument mappings
975        - added new LSCP command "SET VOICES" to globally alter the maximum
976          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
977          be triggered respectively
978        - added new LSCP command "SET STREAMS" to globally alter the maximum
979          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
980          which will be triggered respectively
981        - bugfix: retry if "select" returns EINTR (this fixes a crash when
982          a gigedit file dialog is opened)
983        - close all connections when LSCPServer is deleted
984        - hard close of all sockets on exit
985        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
986          driver
987    
988      * Bug fixes:
989        - fixed a crash which occurs when removing a sampler channel waiting
990          to start instrument loading after another channel
991        - fixed a crash which occurs when removing a sampler channel with
992          instrument loading in progress (bug #113)
993        - fixed termination caused by uncaught exception when adding MIDI
994          instrument with PERSISTENT load mode
995        - fixed possible iterator invalidations when resetting the sampler
996        - fixed memory leaks when issuing the following LSCP commands:
997          GET AUDIO_OUTPUT_DRIVER INFO
998          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
999          GET MIDI_INPUT_DRIVER INFO
1000          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1001        - fixed possible compilation error when sqlite is not present
1002        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1003        - fixed crash when changing the audio output device of a sampler
1004          channel with loaded instrument and start playing notes
1005        - fixed endless loop in Engine::SuspendAll() (bug #120)
1006        - fixed a low-level atomic load function that was broken on 64-bit
1007          PowerPC, which probably could cause crashes on that platform
1008        - fixed a memory management error which could cause a crash when a
1009          plugin was unloaded
1010        - bugfix: two private structs had the same name, which could cause
1011          problems if the linker chose the wrong constructor
1012        - fixed low-level ConditionServer usage bug that caused lockups on
1013          Windows
1014    
1015    
1016    Version 0.5.1 (6 December 2007)
1017    
1018      * packaging changes:
1019        - added autoconf checks for pthread library
1020        - added autoconf check for pthread bug found on certain NPTL-enabled
1021          glibc versions (see Gentoo bug report #194076)
1022        - added autoconf checks for MS Windows
1023    
1024      * general changes:
1025        - bugfix: the thread used by an editor plugin didn't die when the
1026          editor closed
1027        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1028          out all the space. operator--() did not apply size_mask after
1029          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1030          order to avoid problems with the _NonVolatileReader functions.
1031        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1032          GetWriteSpace(). Since this function is currently only used in
1033          the stream's qsort() compare function, it didn't trigger any
1034          bugs.
1035        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1036          24bit mode too. Faster method to read 24bit words on little
1037          endian machines (x86): replaced 3 byte reads + shifts with a 1
1038          unaligned 32bit read and shift
1039        - experimental support for MS Windows (MIDI input via MME, AUDIO
1040          output via ASIO)
1041        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1042        - support for monitoring the total number of active disk streams
1043          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1044          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1045    
1046      * AUDIO driver:
1047        - added Windows ASIO low latency audio driver
1048    
1049      * MIDI driver:
1050        - added MME Windows MIDI driver
1051    
1052      * LSCP server:
1053        - added support for Windows style path / filenames, however with
1054          forward slash path separators instead of backslash
1055          (i.e. "C:/foo/bar.gig")
1056        - allow naughty liblscp to send non-string device parameters within
1057          apostrophes as well
1058        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1059          "LIST FILE INSTRUMENTS <file>" and
1060          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1061          about an arbitrary instrument file on the system where the sampler is
1062          running on
1063    
1064    Version 0.5.0 (15 October 2007)
1065    
1066      * packaging changes:
1067        - config.h is not going to be installed along with liblinuxsampler's
1068          API header files anymore
1069        - only the API relevant header (and source) files will be exported to
1070          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1071        - added completely new XCode project files for Mac OSX which is now
1072          capable to execute our autoconf environment, thus no need anymore
1073          to maintain the compile time configuration file (osx/version.h) for
1074          OSX manually (patch by Toshi Nagata)
1075        - fixed buggy boolean --enable-foo / --disable-foo configure script
1076          parameters
1077        - global.h now only covers global definitions that are needed for the
1078          C++ API header files, all implementation internal global definitions
1079          are now in global_private.h
1080        - atomic.h is not exposed to the C++ API anymore
1081        - no need to include config.h anymore for using LS's API header files
1082        - fixed warnings in API doc generation
1083    
1084      * general changes:
1085        - replaced the old, confusing MIDI program change mechanism by a
1086          flexible MIDI instrument mapper which allows to map arbitrary
1087          (MIDI bank, MIDI program) pairs with arbitrary
1088          (engine type, instrument file, file index) triplets which will be
1089          loaded on the respective channel when such MIDI program change
1090          messages arrive, beside that, each entry allows to define a life-time
1091          strategy for the instrument, so the user can define whether the
1092          instrument should i.e. be permanently loaded (to be able to switch
1093          quickly among sounds) or i.e. loaded just on demand when the
1094          respective program change arrives (to safe RAM space), as well as a
1095          global volume factor for each entry, so the user can adjust the volume
1096          dynamic of his mapped instrument collection without having to modify
1097          the instrument files, also one can manage arbitrary amount of such
1098          MIDI instrument maps and assign each sampler channel individually
1099          a certain map, so that i.e. separation of normal instruments and
1100          drumkits is possible
1101        - new notification events for tracking changes to audio/MIDI devices,
1102          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1103        - sampler was limited to load max. 200 instruments in the background
1104          due to a constant size RingBuffer FIFO which is now replaced by a
1105          dynamic (unlimited) size std::list FIFO
1106        - added FX sends, these allow to route audio signals to arbitrary audio
1107          output channels for being processed by external effect processors
1108          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1109          controllers
1110        - global (sampler wide) volume can now be controlled at runtime
1111        - Implemented new, improved notification system
1112        - fixed compilation errors regarding OSX
1113          (patch by Toshi Nagata)
1114        - implemented instruments database
1115        - added support for escape sequences to the instruments database
1116        - added highly experimental support for on-the-fly instrument editing
1117          within the sampler's process (by using instrument editor plugins),
1118          you'll notice the new "Registered instrument editors:" message on
1119          startup, added a new LSCP command:
1120          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1121          to spawn a matching instrument editor for the instrument on the
1122          given sampler channel, the plugin path can be overridden at compile
1123          time with ./configure --enable-plugin-dir=/some/dir
1124        - added experimental code for synchronizing instrument editors hosted
1125          in the sampler's process to safely edit instruments while playing
1126          without a crash (hopefully) by either suspending single regions
1127          wherever possible or if unavoidable whole engine(s)
1128        - fixed several issues in fundamental "Thread" class: set scheduling
1129          policy and priority on thread level, set a minimum stack size for
1130          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1131          threads simply inherited properties of starting thread instead of
1132          setting their own policy and priority
1133        - minor fix in our automatic stack trace mechanism on crashes, the
1134          main process did not wait for the stack trace process to finish
1135          its output
1136        - fixed some minor memory leaks
1137        - reenabled assembly features support, at the moment only for
1138          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1139        - minor assembly fix in x86 features detection (don't use the PIC
1140          register, to avoid relocations in the text segment at runtime)
1141        - POSIX callback functions of Thread.h are hidden
1142    
1143      * MIDI driver:
1144        - dispatch bank select (MSB and LSB) messages
1145    
1146      * audio driver:
1147        - the ALSA audio output driver parameters now reflect the correct
1148          parameter value ranges for the respective selected sound card
1149          (patch by Till Wimmer, a bit fixed and extended)
1150    
1151      * Gigasampler format engine:
1152        - if a filter is used and EG2 finishes before EG1, let the voice
1153          die when EG2 has finished (this fixes a problem with clicks and
1154          voice starvation for some gigs)
1155        - playback is no longer disabled during instrument loading
1156        - all notes playing on a channel that changes its instrument keep
1157          playing with the old instrument until they get a note off
1158          command
1159        - EG fix: a release value of zero could cause noises or crash
1160        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1161        - EG fine tuning: when attack is zero the EG starts at a level
1162          above max sustain level, which means that there is a decay phase
1163          even if sustain is 100%
1164        - more EG fixes: the level could sometimes go below zero and cause
1165          noises or crashes
1166        - minor fix of EGDecay (patch by Toshi Nagata)
1167        - fixed compiler error when --enable-override-filter-type was
1168          supplied to the configure script (fixes #46)
1169        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1170          instead of a fix value
1171        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1172          127 (solo mode) only kill voices if the respective mode really
1173          changed
1174    
1175      * LSCP server:
1176        - fixed compile time error for old Bison versions
1177          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1178        - parser now supports extended ASCII character set
1179          (up to ASCII code 255, i.e. includes now umlauts and accents)
1180        - filename arguments in LSCP commands now allow to use escape
1181          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1182          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1183          code value like \xf2) (fixes bug #24)
1184        - the following LSCP commands now also support escape sequences for at
1185          least one of their text-based parameters (i.e. name, description):
1186          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1187          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1188          "SET DB_INSTRUMENT_DIRECTORY NAME",
1189          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1190          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1191          "FIND DB_INSTRUMENT_DIRECTORIES"
1192        - returns verbose syntax errors (line and column where syntax error
1193          occured, the unexpected character and the actually expected, possible
1194          character(s), the latter only if less than 5 possibilities)
1195        - made sure that LSCP syntax is not affected by gigedit locale
1196          settings
1197        - bugfix regarding strings parameter lists: all comma separated lists
1198          of strings were treated as being one string containing commas
1199          (fixes #57)
1200    
1201      * Bug fixes:
1202        - fixed crash occurring on certain LSCP scripts (Bug 39)
1203        - another thread safety fix for lscp "load engine" and "set
1204          channel audio output device"
1205        - fixed a crash which occurs when reassigning the same engine
1206          on a sampler channel with connected MIDI device
1207        - fixed a crash which occurs when changing the number of ports of a MIDI
1208          device connected to a sampler channel to number less then or equal
1209          to the index of the port to which the sampler channel is connected.
1210        - The previous bindings were not been disconnected when altering
1211          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1212          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1213        - The active stream/voice count statistic was incorrect.
1214        - notification events were not been sent for some sampler
1215          channel changes
1216        - added default min and max values to restrict the number of allowed
1217          audio output channels and MIDI input ports
1218        - the connection to the PCM interface is now closed when destroying
1219          an audio output device
1220        - files with slash in their path or filename could not be loaded
1221    
1222      * test cases:
