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

264          makefiles
265        - fix for building with bison 3.0 (#202)
266        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
267          on the process's main thread
268        - fixed build error on newer MinGW
269        - support building with older jack versions
270        - support building with spaces in vst sdk path
271        - enabled automake 'subdir-objects' option and moved external
272          source references (vst, au, asio) from makefiles to cpp files,
273          in order to get rid of warnings from automake 1.14
274    
275      * general changes:
276        - Refactoring: moved the independent code from
277          the Gigasampler format engine to base classes
278        - command line option '--profile' is currently disabled, since the
279          respective profiling code is currently broken
280        - Introduced support for optional environment variable
281          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
282          where the sampler shall look for instrument editor plugins
283          (patch by Luis Garrido, slightly modified).
284        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
285        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
286        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
287          note (in this implementation of the sampler its simply hard routed to
288          the 1st effect send of the sampler channel, no matter what the actual
289          effect type is)
290        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
291          note (in this implementation of the sampler its simply hard routed to
292          the 2nd effect send of the sampler channel, no matter what the actual
293          effect type is)
294        - implemented support for internal LADSPA effects
295        - raised limit of program change queue from 100 to 512
296          (as suggested by Alex Stone)
297        - implemented sine LFO, pulse LFO and saw LFO
298        - experimental support for per voice equalization
299        - added command line option --exec-after-init
300        - Introduced new C++ API method:
301          EngineChannel::InstrumentFileName(int index)
302          allowing to retrieve the whole list of files used for the loaded
303          instrument on an engine channel (a.k.a. part). Some GigaStudio
304          instruments for example are splitted over several files like
305          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
306        - Added new C++ API method Sampler::GetGlobalMaxVoices().
307        - Added new C++ API method Sampler::GetGlobalMaxStreams().
308        - Added new C++ API method Sampler::SetGlobalMaxVoices().
309        - Added new C++ API method Sampler::SetGlobalMaxStreams().
310        - Various "const" and "restrict" optimizations.
311        - all engines: add pan CC value to instrument pan parameter before
312          applying panning, instead of using two separate pan functions in
313          series (#182)
314        - added a lock guard class for exception safe mutex handling and
315          used it everywhere appropriate
316        - Immediately apply scale tuning changes to active voices.
317        - Exposed scale tuning to C++ API (along to the already existing standard
318          SysEx way).
319        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
320          and broken for ppc64. (Seq_cst loads and stores are actually not
321          used in LS, so the bug wasn't noticable.)
322        - lsatomic.h: added ARMv7 support
323        - Added support for multiple MIDI input ports per sampler channel (and
324          added various new C++ methods for this new feature / design change, old
325          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
326          as deprecated but are still there and should provide full behavior
327          backward compatibility).
328        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
329          unsafe and caused compilation error with clang 2.x).
330        - Bugfix: only process the latest MIDI program change event.
331        - Introducing the LSCP shell, which provides convenient control of the
332          sampler from the command line by providing LSCP aware features.
333        - VirtualMidiDevice: Added support for program change.
334        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
335        - VirtualMidiDevice: Added support for pitch bend.
336        - Aftertouch: extended API to explicitly handle channel pressure and
337          polyphonic key pressure events (so far polyphonic pressure was not
338          supported at all, and channel pressure was rerouted as CC128 but not
339          used so far).
340        - Added initial support for real-time instrument scripts. The script VM
341          code is shared by all sampler engine implemementations, however only the
342          gig file format currently provides support for storing instrument scripts
343          (as LinuxSampler extension to the original GigaStudio 4 format).
344    
345      * Gigasampler format engine:
346        - implemented the "round robin keyboard" dimension
347        - fixed round robin and random dimensions for cases when number of
348          dimension zones is not a power of two
349        - made round robin use a counter for each region instead of each
350          key
351        - bugfix: pitch LFO controller "internal+aftertouch" was broken
352        - bugfix: filter keyboard tracking was broken
353        - filter performance fix (an unnecessary copy was made of the
354          filter parameters in each sub fragment)
355        - handle special case when pan parameter in gig file has max or
356          min value
357        - Exclusive Groups: don't ever stop voices of the same note,
358          doesn't sound naturally with a drumkit
359        - fixed EG1 modulation when attack or release is zero
360        - Fixed support for 'aftertouch' attenuation controller.
361        - Fixed crash that happened with velocity split sounds under certain
362          conditions (see also previous commit on libgig).
363        - fixed behaviour of filter LFO
364    
365      * SFZ format engine:
366        - Initial implementation (not usable yet)
367        - added support for v2 multiple stage envelope generators
368        - added a fine-tuned v1 envelope generator instead of using the
369          one from the gig engine
370        - fixed memory leak and memory handling errors
371        - added support for trigger=first, trigger=legato and sw_previous

706        - Giga format scripts: Implemented built-in script function
707          "gig_set_dim_zone(event_id, dimension, zone)".
708        - Implemented built-in script int array variable %KEY_DOWN.
709        - Implemented built-in script function "abs()".

716        - Added built-in script int const variables $MARK_1 to $MARK_28.
717        - Built-in script functions "ignore_event()", "note_off()" and
718          "gig_set_dim_zone()" now also accept an array of event IDs as argument
719          (i.e. return value of new script function "by_marks()").
720        - Pass/preserve polyphonic variable data from respective "note" event
721          handler to "release" event handler.
722        - Fixed crash when using built-in script function "by_marks()".
723    
724      * Bug fixes:
725        - Fixed crash which may occur when MIDI key + transpose is out of range
726        - minor valgrind fixes
727        - fixed crash which occurred when changing an already deployed sampler
728          channel to a different engine type
729        - fixed crash when deleting a sampler channel or changing engine
730          type while an instrument load was in progress
731        - bugfix: playing a note while changing the instrument could cause
732          a crash, or give "Handing back unknown region" error messages
733        - bugfix: calling SET VOICES (which Fantasia does on start and
734          refresh) could cause instruments to be unloaded
735        - Mac OS X: fixed name collision of enum in EffectControl and
736          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
737        - Mac OS X: fixed hanging threads
738        - Windows: disabled the previous thread fix on non-Mac systems, as
739          it caused hanging threads on Windows
740        - Fixed possible crashes due to corrupted MIDI/audio device list
741          after MIDI/audio device creation failure
742        - When creating MIDI instrument map entries with "PERSISTENT" type, the
743          instruments were uselessly precached with zero samples, however it still
744          took the full preloading time and on 1st program change the respective
745          instrument was completely reloaded again.
746        - fixed handling of rapid bank select and program change messages
747          sent to the same sampler channel (patch from the Open Octave
748          project, slightly adjusted)
749        - fixed crash when trying to create an effect instance with controls
750          which min and/or max values depend on the sample rate
751        - fixed bug #162
752        - bugfix: LADSPA_PATH was not evaluated correctly when containing
753          multiple paths (#165)
754        - thread safety fixes for the instrument loading thread
755        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
756          (#176)
757        - more thread safety fixes for the instrument loading thread
758        - sfz/sf2 engine: fixed crash when using small audio fragment size
759        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
760        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
761          introduced in previous fix)
762        - fixed crash when a channel received a program change while
763          playing a note in a key group
764        - fixed erroneous error message piping in VoiceBase.h
765          (labelled "Disk stream not available in time")
766        - Update effects on sample rate & period size changes (to avoid
767          crashes and noise on such transitions).
768        - ignore missing LADSPA paths without ignoring valid LADSPA paths
769          (fixes #208)
770        - Fixed bug in LSCP grammar definition which caused a statement like
771          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
772          practically irrelevant, however it caused problems with the new LSCP
773          shell's auto completion feature).
774        - Fixed MIDI program change messages being ignored if quickly executed
775          after each other (fixes #231).
776    
777    Version 1.0.0 (31 July 2009)
778    
779      * packaging changes:
780        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
781          causing e.g. the libgig test to fail when
782          "./configure --disable-jack-driver" was used
783          (patch by Alexis Ballier)
784        - fixed compilation with gcc 4.3
785        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
786        - fixed configure so it detects x86_64 (#107)
787        - fixes for building with newer MinGW versions
788        - fix for building with bison 2.4 (#111)
789        - fixed building with libgig installed in a non-standard directory
790        - minor fix in configure for mmsystem.h detection on MinGW
791        - Windows: look for editor plugins and Fantasia using base
792          directory of liblinuxsampler dll (look in the same directory and one
793          directory above)
794        - configure script fix: removed unconditional use of SSE
795        - fixed building with sqlite installed in a non-standard directory
796        - when cross-compiling, don't try to create instruments.db
797        - fix for new mingw-w64 version, which has usleep
798    
799      * general changes:
800        - bugfix: on some POSIX systems instrument editor plugins refused to
801          load as we used a non-portable Linux specific struct field
802          (fixes bug #70, patch by Ronald Baljeu)
803        - fixed endless loop which occured when loading an instrument editor
804          plugin DLL on Windows systems failed
805        - fixed memory leaks that occurred when liblinuxsampler was unloaded
806        - optimized the SynchronizedConfig class so it doesn't wait
807          unnecessarily long after an update
808        - added support for notifying instrument editors on note-on / note-off
809          events (e.g. to highlight the pressed keys on the virtual keyboard
810          of gigedit)
811        - added support for triggering notes by instrument editors (see above)
812        - be verbose on DLL load errors (on Linux)
813        - fixed di-harmonic triangle LFO implementation (this LFO implementation
814          is only used by very few systems, most pick the int math
815          implementation, which is usually faster)
816        - fixes for audio drivers with varying buffer sizes
817        - experimental support for running LinuxSampler as a DSSI, LV2 and
818          VST plugin
819        - notification events for stream/voice count statistics are now sent
820          only when there are actual changes
821        - added memory ordering constraints to improve stability on
822          multi-core and multi-cpu systems
823        - maximum voices and disk streams can now be altered at runtime
824        - fixed CPU feature detection on x86_64 (maybe fixes #108)
825        - automatic stacktrace mechanism is now turned off by default and can
826          be switched on by command line option "--stacktrace" (the automatic
827          stacktrace mechanism seems to be broken on most systems at the moment)
828        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
829          a pointer to the launched InstrumentEditor object
830        - added optional 3rd party user data parameter for following
831          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
832          InstrumentEditor::Launch(),
833          InstrumentManager::LaunchInstrumentEditor()
834        - theoretical fix: made SynchronizedConfig follow C++0x memory
835          model more strictly
836        - fixes for using large audio device buffers
837        - Windows: add the installation directory to the DLL search path
838          when loading an editor plugin (solves problems with VST and
839          gigedit on systems with other GTK versions installed)
840        - updated linuxsampler man page
841    
842      * audio driver:
843        - removed the nonsense audio channel constraint (which was hard coded to
844          max. 100 audio channels) for most audio drivers
845        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
846          opposed to the LSCP specs
847        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
848          reflected the wrong value
849        - fixed a memory management bug in ASIO driver
850        - Makefile fix: JACK_CFLAGS wasn't used
851        - JACK: use jack_client_open instead of the deprecated
852          jack_client_new
853        - added (experimental) CoreAudio driver
854        - applied old fixes to the ASIO driver that were included in the
855          previous binary release but accidentally never committed to CVS
856          (fixes #117)
857        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
858          win64)
859        - VST: added support for sample rate and buffer size changes
860        - VST: close editor (Fantasia) when the VST is removed
861        - VST: avoid opening Fantasia more than once for each VST instance
862        - VST: export main function as "main" on Linux too (fix for
863          energyXT)
864        - VST: changed number of output channels from one stereo to 16
865          stereo
866        - added channel routing, fxsends and midi maps to the settings
867          stored in the plugin state
868        - performance optimization of AudioChannel::MixTo() and
869          AudioChannel::CopyTo() methods using GCC vector exensions
870          (if available)
871        - ASIO fixes: avoid initializing the device twice, avoid throwing
872          exception when getting parameters from a disconnected device
873    
874      * MIDI driver:
875        - added JACK MIDI driver
876        - dispatch bank select as ordinary CC as well, the user might seriously
877          want to (mis)use it for some purpose ("fixed" in all current MIDI
878          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
879        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
880          CoreMidi or AU
881        - fixed mingw-w64 compilation error in MME driver
882        - made program change handling in MIDI thread real-time safe by
883          moving the logic to a non-RT thread
884        - fixed minor memory leak in ALSA driver
885    
886      * instruments database:
887        - avoid time consuming samples scanning when adding instruments
888          to the instruments database
889        - added support for handling lost files in the instruments database
890        - Implemented option for adding instruments in separate directories
891          in the instruments database
892          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
893        - work-around for missing fnmatch function on Windows to make
894          instrument database compilable
895        - added instrument database support on Windows
896          works with both standalone mode and VST plugin.
897          the instruments DB file is located in
898          %USERPROFILE%\.linuxsampler\instruments.db which allows different
899          databases for each windows user
900          if no DB is present it automatically creates the .linuxsampler subdir
901          and then creates an empty DB
902        - fixed recursive import, which was broken on Windows
903    
904      * Gigasampler format engine:
905        - fixed a memory leak that could happen when a channel was deleted
906          while notes were playing
907        - made it possible to load an instrument even if the audio thread
908          isn't running
909        - added partial support for the "Controller Triggered" MIDI rule,
910          enough for piano gigs with pedal noise samples
911        - minor fix: only mark FX sends as being modified if really the
912          respective FX send MIDI controller was used
913        - added support for GM global device volume SysEx message
914          (can be selected at compile time to either apply globally to the
915          whole sampler [default] or only to the sampler channels that are
916          connected to the respective MIDI input port the SysEx message arrived
917          on)
918        - bugfix: notes triggered at position 0 in the audio buffer were
919          sometimes wrongly killed in the same buffer, causing no sound to
920          be played
921        - added support for chromatic / drumkit mode Roland GS Sysex message
922          which is usally used to switch a part between chromatic sounds and
923          drumkit sounds (as opposed to their common default setting of MIDI
924          part 10 being a drumkit part and all other ones chromatic parts), in
925          LS however one can switch between the first 16 MIDI instrument maps
926          defined for the sampler
927        - made it possible to create multiple sample channels even if the
928          audio thread isn't running
929        - fixed crash when removing channel with active voices (#116)
930        - bugfix: on sample reference changes (instrument editor), only
931          un-cache the respective sample if it's really not used by any
932          sampler engine anymore
933        - re-cache samples in case they were changed by an instrument editor,
934          e.g. when a sample was added while playing (#82)
935        - fixed hanging notes which occured when note-off event had the exact
936          same time stamp as the voice's note-on event and occured both in the
937          same audio fragment cycle (fixes bug #112)
938        - added support for the "fine tune" and "pitch bend range"
939          instrument-level gig parameters
940        - fixed minor artifacts in pitch bend handling
941        - added support for GS Reset SysEx message
942        - allow gig files to use unlimited downward pitch shifting
943        - added a limit check for upward pitch shifting
944        - bugfix: sometimes, when playing a note twice fast, the second
945          note was silent
946        - fixed crash happening when a pitch bend event arrived at the
947          same time a new instrument was loading
948    
949      * LSCP server:
950        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
951          react on MIDI data arriving on certain sampler channels (so far only
952          Note-On and Note-Off events are sent via this LSCP event)
953        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
954          react on MIDI data arriving on certain MIDI input devices (so far only
955          Note-On and Note-Off events are sent via this LSCP event)
956        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
957          SET DB_INSTRUMENT FILE_PATH
958        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
959          frontends to send MIDI messages to specific sampler channel
960        - added two additional fields to GET FILE INSTRUMENT INFO command -
961          KEY_BINDINGS and KEYSWITCH_BINDINGS
962        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
963          was incorrect
964        - Optimized the retrieval of the MIDI instrument mappings
965        - added new LSCP command "SET VOICES" to globally alter the maximum
966          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
967          be triggered respectively
968        - added new LSCP command "SET STREAMS" to globally alter the maximum
969          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
970          which will be triggered respectively
971        - bugfix: retry if "select" returns EINTR (this fixes a crash when
972          a gigedit file dialog is opened)
973        - close all connections when LSCPServer is deleted
974        - hard close of all sockets on exit
975        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
976          driver
977    
978      * Bug fixes:
979        - fixed a crash which occurs when removing a sampler channel waiting
980          to start instrument loading after another channel
981        - fixed a crash which occurs when removing a sampler channel with
982          instrument loading in progress (bug #113)
983        - fixed termination caused by uncaught exception when adding MIDI
984          instrument with PERSISTENT load mode
985        - fixed possible iterator invalidations when resetting the sampler
986        - fixed memory leaks when issuing the following LSCP commands:
987          GET AUDIO_OUTPUT_DRIVER INFO
988          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
989          GET MIDI_INPUT_DRIVER INFO
990          GET MIDI_INPUT_DRIVER_PARAMETER INFO
991        - fixed possible compilation error when sqlite is not present
992        - fixed orphaned pointers when setting maximum voices limit (bug #118)
993        - fixed crash when changing the audio output device of a sampler
994          channel with loaded instrument and start playing notes
995        - fixed endless loop in Engine::SuspendAll() (bug #120)
996        - fixed a low-level atomic load function that was broken on 64-bit
997          PowerPC, which probably could cause crashes on that platform
998        - fixed a memory management error which could cause a crash when a
999          plugin was unloaded
1000        - bugfix: two private structs had the same name, which could cause
1001          problems if the linker chose the wrong constructor
1002        - fixed low-level ConditionServer usage bug that caused lockups on
1003          Windows
1004    
1005    
1006    Version 0.5.1 (6 December 2007)
1007    
1008      * packaging changes:
1009        - added autoconf checks for pthread library
1010        - added autoconf check for pthread bug found on certain NPTL-enabled
1011          glibc versions (see Gentoo bug report #194076)
1012        - added autoconf checks for MS Windows
1013    
1014      * general changes:
1015        - bugfix: the thread used by an editor plugin didn't die when the
1016          editor closed
1017        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1018          out all the space. operator--() did not apply size_mask after
1019          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1020          order to avoid problems with the _NonVolatileReader functions.
1021        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1022          GetWriteSpace(). Since this function is currently only used in
1023          the stream's qsort() compare function, it didn't trigger any
1024          bugs.
1025        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1026          24bit mode too. Faster method to read 24bit words on little
1027          endian machines (x86): replaced 3 byte reads + shifts with a 1
1028          unaligned 32bit read and shift
1029        - experimental support for MS Windows (MIDI input via MME, AUDIO
1030          output via ASIO)
1031        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1032        - support for monitoring the total number of active disk streams
1033          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1034          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1035    
1036      * AUDIO driver:
1037        - added Windows ASIO low latency audio driver
1038    
1039      * MIDI driver:
1040        - added MME Windows MIDI driver
1041    
1042      * LSCP server:
1043        - added support for Windows style path / filenames, however with
1044          forward slash path separators instead of backslash
1045          (i.e. "C:/foo/bar.gig")
1046        - allow naughty liblscp to send non-string device parameters within
1047          apostrophes as well
1048        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1049          "LIST FILE INSTRUMENTS <file>" and
1050          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1051          about an arbitrary instrument file on the system where the sampler is
1052          running on
1053    
1054    Version 0.5.0 (15 October 2007)
1055    
1056      * packaging changes:
1057        - config.h is not going to be installed along with liblinuxsampler's
1058          API header files anymore
1059        - only the API relevant header (and source) files will be exported to
1060          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1061        - added completely new XCode project files for Mac OSX which is now
1062          capable to execute our autoconf environment, thus no need anymore
1063          to maintain the compile time configuration file (osx/version.h) for
1064          OSX manually (patch by Toshi Nagata)
1065        - fixed buggy boolean --enable-foo / --disable-foo configure script
1066          parameters
1067        - global.h now only covers global definitions that are needed for the
1068          C++ API header files, all implementation internal global definitions
1069          are now in global_private.h
1070        - atomic.h is not exposed to the C++ API anymore
1071        - no need to include config.h anymore for using LS's API header files
1072        - fixed warnings in API doc generation

1100      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
1101        - Implemented new, improved notification system
1102        - fixed compilation errors regarding OSX
1103          (patch by Toshi Nagata)
1104        - implemented instruments database
1105        - added support for escape sequences to the instruments database
1106        - added highly experimental support for on-the-fly instrument editing
1107          within the sampler's process (by using instrument editor plugins),
1108          you'll notice the new "Registered instrument editors:" message on
1109          startup, added a new LSCP command:
1110          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1111          to spawn a matching instrument editor for the instrument on the
1112          given sampler channel, the plugin path can be overridden at compile
1113          time with ./configure --enable-plugin-dir=/some/dir
1114        - added experimental code for synchronizing instrument editors hosted
1115          in the sampler's process to safely edit instruments while playing
1116          without a crash (hopefully) by either suspending single regions
1117          wherever possible or if unavoidable whole engine(s)
1118        - fixed several issues in fundamental "Thread" class: set scheduling
1119          policy and priority on thread level, set a minimum stack size for
1120          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1121          threads simply inherited properties of starting thread instead of
1122          setting their own policy and priority
1123        - minor fix in our automatic stack trace mechanism on crashes, the
1124          main process did not wait for the stack trace process to finish
1125          its output
1126        - fixed some minor memory leaks
1127        - reenabled assembly features support, at the moment only for
1128          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1129        - minor assembly fix in x86 features detection (don't use the PIC
1130          register, to avoid relocations in the text segment at runtime)
1131        - POSIX callback functions of Thread.h are hidden

1154        - more EG fixes: the level could sometimes go below zero and cause
1155          noises or crashes
1156        - minor fix of EGDecay (patch by Toshi Nagata)
1157        - fixed compiler error when --enable-override-filter-type was
1158          supplied to the configure script (fixes #46)
1159        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1160          instead of a fix value
1161        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1162          127 (solo mode) only kill voices if the respective mode really
1163          changed
1164    
1165      * LSCP server:
1166        - fixed compile time error for old Bison versions
1167          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1168        - parser now supports extended ASCII character set
1169          (up to ASCII code 255, i.e. includes now umlauts and accents)
1170        - filename arguments in LSCP commands now allow to use escape
1171          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1172          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1173          code value like \xf2) (fixes bug #24)
1174        - the following LSCP commands now also support escape sequences for at
1175          least one of their text-based parameters (i.e. name, description):
1176          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1177          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1178          "SET DB_INSTRUMENT_DIRECTORY NAME",
1179          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1180          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1181          "FIND DB_INSTRUMENT_DIRECTORIES"
1182        - returns verbose syntax errors (line and column where syntax error
1183          occured, the unexpected character and the actually expected, possible
1184          character(s), the latter only if less than 5 possibilities)
1185        - made sure that LSCP syntax is not affected by gigedit locale
1186          settings
1187        - bugfix regarding strings parameter lists: all comma separated lists
1188          of strings were treated as being one string containing commas
1189          (fixes #57)
1190    
1191    * Bug fixes:    * Bug fixes:
1192      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
1193      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
1194        channel audio output device"        channel audio output device"
1195        - fixed a crash which occurs when reassigning the same engine
1196          on a sampler channel with connected MIDI device
1197        - fixed a crash which occurs when changing the number of ports of a MIDI
1198          device connected to a sampler channel to number less then or equal
1199          to the index of the port to which the sampler channel is connected.
1200        - The previous bindings were not been disconnected when altering
1201          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1202          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1203        - The active stream/voice count statistic was incorrect.
1204        - notification events were not been sent for some sampler
1205          channel changes
1206        - added default min and max values to restrict the number of allowed
1207          audio output channels and MIDI input ports
1208        - the connection to the PCM interface is now closed when destroying
1209          an audio output device
1210        - files with slash in their path or filename could not be loaded
1211
