# 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    
11      * Gigasampler/GigaStudio format engine:
12        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13          cutoff settings.
14    
15      * general changes:
16        - fixed printf type errors (mostly in debug messages)
17        - use unique_ptr instead of auto_ptr when building with C++11
18        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19          allowing to sort data efficiently in real-time safe manner.
20        - RTList class: added methods for moving/inserting elements to arbitrary
21          position within a list.
22        - RTList class: added method fromPtr() for creating an Iterator object from
23          a raw element pointer.
24        - Attempt to partly fix resetting engine channels vs. resetting engine, an
25          overall cleanup of the Reset*(), ConnectAudioDevice(),
26          DisconnectAudioDevice() API methods would still be desirable though,
27          because the current situation is still inconsistent and error prone.
28        - Active voices are now internally grouped to "Note" objects, instead of
29          being directly assigned to a keyboard key. This allows more fine graded
30          processing of voices, which is i.e. required for certain instrument
31          script features.
32        - Fix: Release trigger voices were not spawned on sustain pedal up
33          (CC #64) events.
34        - Fix: Release trigger voices can now also distinguish correctly between
35          note-off and sustain pedal up events.
36        - All engines: Increased ramp speed of volume smoother and pan smoother
37          (while slow rate of crossfade smoother is preserved) to allow quick
38          volume and pan changes by instrument scripts for instance.
39        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40          properly and thus were ignored for certain uses.
41        - Added new C++ API method
42          VirtualMidiDevice::SendChannelPressureToSampler().
43        - windows, 32-bit: fixed potential crashes by making sure the stack in
44          sub threads is 16-byte aligned
45        - fixed numerous compiler warnings
46        - Fixed invalid (note-on) event ID being assigned to new Note objects.
47    
48      * packaging changes:
49        - removed unnecessary dependency to libuuid
50          (originated by libgig's usage of it)
51        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52          auto detect whether it (sh/c)ould output its messages in color.
53    
54      * Real-time instrument scripts:
55        - Implemented scheduler for delayed MIDI events and for suspended scripts.
56        - Built-in script function "wait()": implemented support for function's
57          "duration-us" argument, thus scripts using this function are now
58          correctly resumed after the requested amount of microseconds.
59        - Built-in script function "play_note()": implemented support for
60          function's "duration-us" argument, thus notes triggered with this
61          argument are now correctly released after the requested amount of
62          microseconds.
63        - Fix: script events were not cleared when engine channel was reset,
64          potentially causing undefined behavior.
65        - Fixed crash which happened when trying to reference an undeclared
66          variable.
67        - Built-in script function "play_note()": Added support for passing
68          special value -1 for "duration-us" argument, which will cause the
69          triggered note to be released once the original note was released.
70        - Instrument script classes now exported with the liblinuxsampler C++ API.
71        - Added new API method ScriptVM::syntaxHighlighting() which provides
72          a convenient syntax highlighting backend for external instrument
73          script editor applications.
74        - Added new C++ API class "ScriptVMFactory".
75        - Extended parser issues to provide not only first line and first
76          column, but also last line and last column of issue (thus marking
77          the precise span of the issue within the source code).
78        - Reload script automatically after being modified by an instrument
79          editor.
80        - NKSP language grammar correction: allow empty event handler bodies
81          like "on note end on".
82        - Implemented built-in script function "change_vol()".
83        - Implemented built-in script function "change_tune()".
84        - Implemented built-in script function "change_pan()".
85        - Implemented built-in script function "change_cutoff()".
86        - Implemented built-in script function "change_reso()".
87        - Implemented built-in script function "event_status()".
88        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90          "event_status()" function.
91        - NKSP language: Added support for bitwise operators ".or.", ".and."
92          and ".not.".
93        - NKSP language scanner: Fixed IDs matching to require at least one
94          character (i.e. when matching function names or variable names).
95        - NKSP language scanner: disabled unusued rules.
96        - Fixed behavior of play_note() and note_off() functions which must
97          be distinguished engine internally from "real" MIDI note on/off
98          events in order to avoid misbehaviors like hanging notes.
99        - Implemented built-in script variable "$KSP_TIMER".
100        - Implemented built-in script variable "$NKSP_REAL_TIMER".
101        - Implemented built-in script variable "$NKSP_PERF_TIMER".
102        - Implemented built-in script variable "$ENGINE_UPTIME".
103        - Implemented built-in script function "inc()".
104        - Implemented built-in script function "dec()".
105        - NKSP language fix: division expressions were evaluated too often.
106        - NKSP language fix: string concatenation operator was right
107          associative instead of left (to right).
108        - NKSP language correction: allow empty statements in entire language
109          (i.e. "if end if").
110        - Implemented built-in script function "stop_wait()".
111        - Implemented built-in script variable "$NI_CALLBACK_ID".
112        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114        - Added support for read-only built-in variables (respectively
115          handled by the script parser).
116        - Added built-in script constant "$NI_CB_TYPE_INIT".
117        - Added built-in script constant "$NI_CB_TYPE_NOTE".
118        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120        - NKSP Language: Added support for user defined script functions.
121        - Implemented built-in script function "change_attack()".
122        - Implemented built-in script function "change_decay()".
123        - Implemented built-in script function "change_release()".
124        - Fixed all change_*() built-in script functions to apply their
125          synthesis parameter changes immediately in case the respective note
126          was triggered at the same time, instead of scheduling the parameter
127          change, especially because it would cause some parameter types's
128          changes either to be ramped (i.e. change_vol()) or other types even
129          to have not effect at all (i.e. change_attack()).
130        - Implemented built-in script function "sh_left()".
131        - Implemented built-in script function "sh_right()".
132        - Implemented built-in script function "min()".
133        - Implemented built-in script function "max()".
134        - NKSP Fix: "init" event handler was not always executed when a script
135          was loaded.
136        - NKSP built-in wait() script function: abort script execution if
137          a negative or zero wait time was passed as argument (since this is
138          a common indication of a bug either of the script or even of the
139          engine, which could lead to RT instability or even worse).
140        - ScriptVM: Implemented automatic suspension of RT safety
141          threatening scripts.
142        - Provide more user friendly error messages on syntax errors.
143        - Fixed NKSP parser warning "Not a statement" when assigning an
144          initializer list to an array variable.
145        - Implemented built-in script array variable "%ALL_EVENTS".
146        - Implemented built-in script function "in_range()".
147        - Implemented built-in script function "change_amp_lfo_depth()".
148        - Implemented built-in script function "change_amp_lfo_freq()".
149        - Implemented built-in script function "change_pitch_lfo_depth()".
150        - Implemented built-in script function "change_pitch_lfo_freq()".
151        - Implemented built-in script function "change_vol_time()".
152        - Implemented built-in script function "change_tune_time()".
153        - Implemented built-in script function "fade_in()".
154        - Implemented built-in script function "fade_out()".
155        - Fixed acceptance of wrong data type of parameters passed to built-in
156          script functions "change_vol()", "change_tune()", "change_pan()",
157          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160        - Added built-in script function "get_event_par()" and implemented some
161          of its possible parameter selections.
162        - Added built-in script function "set_event_par()" and implemented some
163          of its possible parameter selections.
164        - Fixed a bunch of scheduler time related bugs.
165        - Fixed polyphonic variables not being reset to zero after usage.
166        - Built-in "ignore_event()" function: argument is now optional, like with
167          built-in function "ignore_controller()".
168        - Implemented built-in script function "change_velo()".
169        - Implemented built-in script function "change_note()".
170        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171          intuitive behavior if used in combination with "change_vol_time()" or
172          "change_tune_time()" respectively: now tuning/volume changes are only
173          assigned (without delay) immediately to a new note if the respective
174          timing function has not been called before, otherwise the volume/tuning
175          changes are automatically faded (before, only the event's time stamp was
176          relevant).
177         - Implemented built-in script function "array_equal()".
178         - Implemented built-in script function "search()".
179         - Implemented built-in script function "sort()".
180         - NKSP Fix: Never suspend "init" event handlers.
181         - Implemented built-in script function "same_region()" (currently only
182           available for gig format engine).
183         - Added built-in script constant "$NKSP_LINEAR".
184         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
185         - Implemented built-in script function "change_vol_curve()".
186         - Implemented built-in script function "change_tune_curve()".
187         - built-in "play_note()" function now supports a sample playback start
188           offset with argument 3, where special value -1 means to use the regular
189           sample offset as defined by the instrument file.
190         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
191         - Built-in variable $EVENT_NOTE is now a read-only variable.
192         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
193         - built-in "play_note()" function now accepts -2 for its fourth argument
194           (note duration) which means the life time of the note shall be sticked
195           to the requested note number of argument 1.
196         - Fix: built-in "play_note()" function now returns 0 as result value if
197           -1 was passed for its fourth argument (note duration) and the respective
198           parent note is already gone.
199        - Implemented built-in script function "change_play_pos()".
200        - NKSP language: Added support for user declared const array variables.
201        - NKSP language: Raise parser warning if array variable is accessed with
202          an index that exceeds the array's size.
203    
204      * Instruments DB:
205        - Fixed memory access bug of general DB access code which lead to
206          undefined behavior.
207        - Cleanup of instruments DB file creation and opening code.
208        - The instrument DB path of linuxsampler's --create-instruments-db argument
209          is now optional, if it is missing, then a default location is used.
210        - Added support for scanning SFZ (.sfz) files.
211        - Added support for scanning Sound Font (.sf2) files.
212        - Fixed undefined DB transaction behavior.
213    
214    Version 2.0.0 (15 July 2015)
215    
216      * packaging changes:
217        - fixed building with newer MinGW-w64
218        - Mac OS X: support the new dir for Core Audio SDK
219        - Mac OS X: fixed building outside source directory
220        - made sure all source files for hostplugins are included when
221          doing "make dist"
222        - removed empty directories left from the cvs to svn migration
223        - fixed compilation with gcc 4.6.1
224        - another "make dist" fix, for the LV2 plugin
225        - made --enable-pthread-testcancel default on Mac OS X
226        - minor Makefile fix for building lscpparser when build and source
227          directories are separate
228        - Mac OS X: made it possible to specify plugin installation dir to
229          configure
230        - Mac OS X: Makefile fix for the install-strip target
231        - fixed compilation with gcc 4.7
232        - fixed configure script error with old autoconf versions
233        - lsatomic.h: use gcc provided atomic functions if building with
234          gcc 4.7 and C++11
235        - modernized configure script
236        - fixed linkage error when building with
237          LDFLAGS="-Wl,--no-undefined" (#190)
238        - fixed compilation with Clang 3.2
239        - removed usage of deprecated Automake variable INCLUDES
240        - fixed building with C++11
241        - build fix: ChangeFlagRelaxed.h was missing in makefile
242        - build fix: libsndfile compiler flags were missing in some
243          makefiles
244        - fix for building with bison 3.0 (#202)
245        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
246          on the process's main thread
247        - fixed build error on newer MinGW
248        - support building with older jack versions
249        - support building with spaces in vst sdk path
250        - enabled automake 'subdir-objects' option and moved external
251          source references (vst, au, asio) from makefiles to cpp files,
252          in order to get rid of warnings from automake 1.14
253    
254      * general changes:
255        - Refactoring: moved the independent code from
256          the Gigasampler format engine to base classes
257        - command line option '--profile' is currently disabled, since the
258          respective profiling code is currently broken
259        - Introduced support for optional environment variable
260          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
261          where the sampler shall look for instrument editor plugins
262          (patch by Luis Garrido, slightly modified).
263        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
264        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
265        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
266          note (in this implementation of the sampler its simply hard routed to
267          the 1st effect send of the sampler channel, no matter what the actual
268          effect type is)
269        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
270          note (in this implementation of the sampler its simply hard routed to
271          the 2nd effect send of the sampler channel, no matter what the actual
272          effect type is)
273        - implemented support for internal LADSPA effects
274        - raised limit of program change queue from 100 to 512
275          (as suggested by Alex Stone)
276        - implemented sine LFO, pulse LFO and saw LFO
277        - experimental support for per voice equalization
278        - added command line option --exec-after-init
279        - Introduced new C++ API method:
280          EngineChannel::InstrumentFileName(int index)
281          allowing to retrieve the whole list of files used for the loaded
282          instrument on an engine channel (a.k.a. part). Some GigaStudio
283          instruments for example are splitted over several files like
284          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
285        - Added new C++ API method Sampler::GetGlobalMaxVoices().
286        - Added new C++ API method Sampler::GetGlobalMaxStreams().
287        - Added new C++ API method Sampler::SetGlobalMaxVoices().
288        - Added new C++ API method Sampler::SetGlobalMaxStreams().
289        - Various "const" and "restrict" optimizations.
290        - all engines: add pan CC value to instrument pan parameter before
291          applying panning, instead of using two separate pan functions in
292          series (#182)
293        - added a lock guard class for exception safe mutex handling and
294          used it everywhere appropriate
295        - Immediately apply scale tuning changes to active voices.
296        - Exposed scale tuning to C++ API (along to the already existing standard
297          SysEx way).
298        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
299          and broken for ppc64. (Seq_cst loads and stores are actually not
300          used in LS, so the bug wasn't noticable.)
301        - lsatomic.h: added ARMv7 support
302        - Added support for multiple MIDI input ports per sampler channel (and
303          added various new C++ methods for this new feature / design change, old
304          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
305          as deprecated but are still there and should provide full behavior
306          backward compatibility).
307        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
308          unsafe and caused compilation error with clang 2.x).
309        - Bugfix: only process the latest MIDI program change event.
310        - Introducing the LSCP shell, which provides convenient control of the
311          sampler from the command line by providing LSCP aware features.
312        - VirtualMidiDevice: Added support for program change.
313        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
314        - VirtualMidiDevice: Added support for pitch bend.
315        - Aftertouch: extended API to explicitly handle channel pressure and
316          polyphonic key pressure events (so far polyphonic pressure was not
317          supported at all, and channel pressure was rerouted as CC128 but not
318          used so far).
319        - Added initial support for real-time instrument scripts. The script VM
320          code is shared by all sampler engine implemementations, however only the
321          gig file format currently provides support for storing instrument scripts
322          (as LinuxSampler extension to the original GigaStudio 4 format).
323    
324      * Gigasampler format engine:
325        - implemented the "round robin keyboard" dimension
326        - fixed round robin and random dimensions for cases when number of
327          dimension zones is not a power of two
328        - made round robin use a counter for each region instead of each
329          key
330        - bugfix: pitch LFO controller "internal+aftertouch" was broken
331        - bugfix: filter keyboard tracking was broken
332        - filter performance fix (an unnecessary copy was made of the
333          filter parameters in each sub fragment)
334        - handle special case when pan parameter in gig file has max or
335          min value
336        - Exclusive Groups: don't ever stop voices of the same note,
337          doesn't sound naturally with a drumkit
338        - fixed EG1 modulation when attack or release is zero
339        - Fixed support for 'aftertouch' attenuation controller.
340        - Fixed crash that happened with velocity split sounds under certain
341          conditions (see also previous commit on libgig).
342        - fixed behaviour of filter LFO
343    
344      * SFZ format engine:
345        - Initial implementation (not usable yet)
346        - added support for v2 multiple stage envelope generators
347        - added a fine-tuned v1 envelope generator instead of using the
348          one from the gig engine
349        - fixed memory leak and memory handling errors
350        - added support for trigger=first, trigger=legato and sw_previous
351        - allow non-numerical key values ("C#4" for example)
352        - "key" opcode now sets pitch_keycenter too
353        - fixed error when unloading instrument with same sample used by
354          multiple regions
355        - added some opcode aliases, like loopmode for loop_mode, to be
356          more compatible
357        - added support for trigger=release and rt_decay
358        - added support for off_mode=normal
359        - added support for random, seq_position, seq_length and volume
360        - added v1 LFO opcodes to parser (no support in engine yet)
361        - added support for amp_veltrack and amp_velcurve_N
362        - fine-tuned the default velocity curve
363        - added support for transpose
364        - fixed crash when using sw_down/up
365        - improved logic for sw_lokey/hikey/up/down/last
366        - added more v1 aliases to parser
367        - reduced memory usage for sfz data
368        - RT-safeness: avoid malloc in audio thread
369        - fixed a bug that could cause voice stealing to fail
370        - optimized sample lookup
371        - improved support for exclusive groups (group, off_by and
372          off_mode)
373        - added support for controller triggered regions (on_locc/on_hicc)

690        - Implemented built-in script function "num_elements()".
691        - Implemented built-in script function "note_off()".
692        - Implemented built-in script function "set_event_mark()".
693        - Implemented built-in script function "delete_event_mark()".
694        - Implemented built-in script function "by_marks()".
695        - Added built-in script int const variables $MARK_1 to $MARK_28.
696        - Built-in script functions "ignore_event()", "note_off()" and
697          "gig_set_dim_zone()" now also accept an array of event IDs as argument
698          (i.e. return value of new script function "by_marks()").
699        - Pass/preserve polyphonic variable data from respective "note" event
700          handler to "release" event handler.
701        - Fixed crash when using built-in script function "by_marks()".
702    
703      * Bug fixes:
704        - Fixed crash which may occur when MIDI key + transpose is out of range
705        - minor valgrind fixes
706        - fixed crash which occurred when changing an already deployed sampler
707          channel to a different engine type
708        - fixed crash when deleting a sampler channel or changing engine
709          type while an instrument load was in progress
710        - bugfix: playing a note while changing the instrument could cause
711          a crash, or give "Handing back unknown region" error messages
712        - bugfix: calling SET VOICES (which Fantasia does on start and
713          refresh) could cause instruments to be unloaded
714        - Mac OS X: fixed name collision of enum in EffectControl and
715          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
716        - Mac OS X: fixed hanging threads
717        - Windows: disabled the previous thread fix on non-Mac systems, as
718          it caused hanging threads on Windows
719        - Fixed possible crashes due to corrupted MIDI/audio device list
720          after MIDI/audio device creation failure
721        - When creating MIDI instrument map entries with "PERSISTENT" type, the
722          instruments were uselessly precached with zero samples, however it still
723          took the full preloading time and on 1st program change the respective
724          instrument was completely reloaded again.
725        - fixed handling of rapid bank select and program change messages
726          sent to the same sampler channel (patch from the Open Octave
727          project, slightly adjusted)
728        - fixed crash when trying to create an effect instance with controls
729          which min and/or max values depend on the sample rate
730        - fixed bug #162
731        - bugfix: LADSPA_PATH was not evaluated correctly when containing
732          multiple paths (#165)
733        - thread safety fixes for the instrument loading thread
734        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
735          (#176)
736        - more thread safety fixes for the instrument loading thread
737        - sfz/sf2 engine: fixed crash when using small audio fragment size
738        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
739        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
740          introduced in previous fix)
741        - fixed crash when a channel received a program change while
742          playing a note in a key group
743        - fixed erroneous error message piping in VoiceBase.h
744          (labelled "Disk stream not available in time")
745        - Update effects on sample rate & period size changes (to avoid
746          crashes and noise on such transitions).
747        - ignore missing LADSPA paths without ignoring valid LADSPA paths
748          (fixes #208)
749        - Fixed bug in LSCP grammar definition which caused a statement like
750          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
751          practically irrelevant, however it caused problems with the new LSCP
752          shell's auto completion feature).
753        - Fixed MIDI program change messages being ignored if quickly executed
754          after each other (fixes #231).
755    
756    Version 1.0.0 (31 July 2009)
757    
758      * packaging changes:
759        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
760          causing e.g. the libgig test to fail when
761          "./configure --disable-jack-driver" was used
762          (patch by Alexis Ballier)
763        - fixed compilation with gcc 4.3
764        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
765        - fixed configure so it detects x86_64 (#107)
766        - fixes for building with newer MinGW versions
767        - fix for building with bison 2.4 (#111)
768        - fixed building with libgig installed in a non-standard directory
769        - minor fix in configure for mmsystem.h detection on MinGW
770        - Windows: look for editor plugins and Fantasia using base
771          directory of liblinuxsampler dll (look in the same directory and one
772          directory above)
773        - configure script fix: removed unconditional use of SSE
774        - fixed building with sqlite installed in a non-standard directory
775        - when cross-compiling, don't try to create instruments.db
776        - fix for new mingw-w64 version, which has usleep
777    
778      * general changes:
779        - bugfix: on some POSIX systems instrument editor plugins refused to
780          load as we used a non-portable Linux specific struct field
781          (fixes bug #70, patch by Ronald Baljeu)
782        - fixed endless loop which occured when loading an instrument editor
783          plugin DLL on Windows systems failed
784        - fixed memory leaks that occurred when liblinuxsampler was unloaded
785        - optimized the SynchronizedConfig class so it doesn't wait
786          unnecessarily long after an update
787        - added support for notifying instrument editors on note-on / note-off
788          events (e.g. to highlight the pressed keys on the virtual keyboard
789          of gigedit)
790        - added support for triggering notes by instrument editors (see above)
791        - be verbose on DLL load errors (on Linux)
792        - fixed di-harmonic triangle LFO implementation (this LFO implementation
793          is only used by very few systems, most pick the int math
794          implementation, which is usually faster)
795        - fixes for audio drivers with varying buffer sizes
796        - experimental support for running LinuxSampler as a DSSI, LV2 and
797          VST plugin
798        - notification events for stream/voice count statistics are now sent
799          only when there are actual changes
800        - added memory ordering constraints to improve stability on
801          multi-core and multi-cpu systems
802        - maximum voices and disk streams can now be altered at runtime
803        - fixed CPU feature detection on x86_64 (maybe fixes #108)
804        - automatic stacktrace mechanism is now turned off by default and can
805          be switched on by command line option "--stacktrace" (the automatic
806          stacktrace mechanism seems to be broken on most systems at the moment)
807        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
808          a pointer to the launched InstrumentEditor object
809        - added optional 3rd party user data parameter for following
810          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
811          InstrumentEditor::Launch(),
812          InstrumentManager::LaunchInstrumentEditor()
813        - theoretical fix: made SynchronizedConfig follow C++0x memory
814          model more strictly
815        - fixes for using large audio device buffers
816        - Windows: add the installation directory to the DLL search path
817          when loading an editor plugin (solves problems with VST and
818          gigedit on systems with other GTK versions installed)
819        - updated linuxsampler man page
820    
821      * audio driver:
822        - removed the nonsense audio channel constraint (which was hard coded to
823          max. 100 audio channels) for most audio drivers
824        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
825          opposed to the LSCP specs
826        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
827          reflected the wrong value
828        - fixed a memory management bug in ASIO driver
829        - Makefile fix: JACK_CFLAGS wasn't used
830        - JACK: use jack_client_open instead of the deprecated
831          jack_client_new
832        - added (experimental) CoreAudio driver
833        - applied old fixes to the ASIO driver that were included in the
834          previous binary release but accidentally never committed to CVS
835          (fixes #117)
836        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
837          win64)
838        - VST: added support for sample rate and buffer size changes
839        - VST: close editor (Fantasia) when the VST is removed
840        - VST: avoid opening Fantasia more than once for each VST instance
841        - VST: export main function as "main" on Linux too (fix for
842          energyXT)
843        - VST: changed number of output channels from one stereo to 16
844          stereo
845        - added channel routing, fxsends and midi maps to the settings
846          stored in the plugin state
847        - performance optimization of AudioChannel::MixTo() and
848          AudioChannel::CopyTo() methods using GCC vector exensions
849          (if available)
850        - ASIO fixes: avoid initializing the device twice, avoid throwing
851          exception when getting parameters from a disconnected device
852    
853      * MIDI driver:
854        - added JACK MIDI driver
855        - dispatch bank select as ordinary CC as well, the user might seriously
856          want to (mis)use it for some purpose ("fixed" in all current MIDI
857          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
858        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
859          CoreMidi or AU
860        - fixed mingw-w64 compilation error in MME driver
861        - made program change handling in MIDI thread real-time safe by
862          moving the logic to a non-RT thread
863        - fixed minor memory leak in ALSA driver
864    
865      * instruments database:
866        - avoid time consuming samples scanning when adding instruments
867          to the instruments database
868        - added support for handling lost files in the instruments database
869        - Implemented option for adding instruments in separate directories
870          in the instruments database
871          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
872        - work-around for missing fnmatch function on Windows to make
873          instrument database compilable
874        - added instrument database support on Windows
875          works with both standalone mode and VST plugin.
876          the instruments DB file is located in
877          %USERPROFILE%\.linuxsampler\instruments.db which allows different
878          databases for each windows user
879          if no DB is present it automatically creates the .linuxsampler subdir
880          and then creates an empty DB
881        - fixed recursive import, which was broken on Windows
882    
883      * Gigasampler format engine:
884        - fixed a memory leak that could happen when a channel was deleted
885          while notes were playing
886        - made it possible to load an instrument even if the audio thread
887          isn't running
888        - added partial support for the "Controller Triggered" MIDI rule,
889          enough for piano gigs with pedal noise samples
890        - minor fix: only mark FX sends as being modified if really the
891          respective FX send MIDI controller was used
892        - added support for GM global device volume SysEx message
893          (can be selected at compile time to either apply globally to the
894          whole sampler [default] or only to the sampler channels that are
895          connected to the respective MIDI input port the SysEx message arrived
896          on)
897        - bugfix: notes triggered at position 0 in the audio buffer were
898          sometimes wrongly killed in the same buffer, causing no sound to
899          be played
900        - added support for chromatic / drumkit mode Roland GS Sysex message
901          which is usally used to switch a part between chromatic sounds and
902          drumkit sounds (as opposed to their common default setting of MIDI
903          part 10 being a drumkit part and all other ones chromatic parts), in
904          LS however one can switch between the first 16 MIDI instrument maps
905          defined for the sampler
906        - made it possible to create multiple sample channels even if the
907          audio thread isn't running
908        - fixed crash when removing channel with active voices (#116)
909        - bugfix: on sample reference changes (instrument editor), only
910          un-cache the respective sample if it's really not used by any
911          sampler engine anymore
912        - re-cache samples in case they were changed by an instrument editor,
913          e.g. when a sample was added while playing (#82)
914        - fixed hanging notes which occured when note-off event had the exact
915          same time stamp as the voice's note-on event and occured both in the
916          same audio fragment cycle (fixes bug #112)
917        - added support for the "fine tune" and "pitch bend range"
918          instrument-level gig parameters
919        - fixed minor artifacts in pitch bend handling
920        - added support for GS Reset SysEx message
921        - allow gig files to use unlimited downward pitch shifting
922        - added a limit check for upward pitch shifting
923        - bugfix: sometimes, when playing a note twice fast, the second
924          note was silent
925        - fixed crash happening when a pitch bend event arrived at the
926          same time a new instrument was loading
927    
928      * LSCP server:
929        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
930          react on MIDI data arriving on certain sampler channels (so far only
931          Note-On and Note-Off events are sent via this LSCP event)
932        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
933          react on MIDI data arriving on certain MIDI input devices (so far only
934          Note-On and Note-Off events are sent via this LSCP event)
935        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
936          SET DB_INSTRUMENT FILE_PATH
937        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
938          frontends to send MIDI messages to specific sampler channel
939        - added two additional fields to GET FILE INSTRUMENT INFO command -
940          KEY_BINDINGS and KEYSWITCH_BINDINGS
941        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
942          was incorrect
943        - Optimized the retrieval of the MIDI instrument mappings
944        - added new LSCP command "SET VOICES" to globally alter the maximum
945          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
946          be triggered respectively
947        - added new LSCP command "SET STREAMS" to globally alter the maximum
948          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
949          which will be triggered respectively
950        - bugfix: retry if "select" returns EINTR (this fixes a crash when
951          a gigedit file dialog is opened)
952        - close all connections when LSCPServer is deleted
953        - hard close of all sockets on exit
954        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
955          driver
956    
957      * Bug fixes:
958        - fixed a crash which occurs when removing a sampler channel waiting
959          to start instrument loading after another channel
960        - fixed a crash which occurs when removing a sampler channel with
961          instrument loading in progress (bug #113)
962        - fixed termination caused by uncaught exception when adding MIDI
963          instrument with PERSISTENT load mode
964        - fixed possible iterator invalidations when resetting the sampler
965        - fixed memory leaks when issuing the following LSCP commands:
966          GET AUDIO_OUTPUT_DRIVER INFO
967          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
968          GET MIDI_INPUT_DRIVER INFO
969          GET MIDI_INPUT_DRIVER_PARAMETER INFO
970        - fixed possible compilation error when sqlite is not present
971        - fixed orphaned pointers when setting maximum voices limit (bug #118)
972        - fixed crash when changing the audio output device of a sampler
973          channel with loaded instrument and start playing notes
974        - fixed endless loop in Engine::SuspendAll() (bug #120)
975        - fixed a low-level atomic load function that was broken on 64-bit
976          PowerPC, which probably could cause crashes on that platform
977        - fixed a memory management error which could cause a crash when a
978          plugin was unloaded
979        - bugfix: two private structs had the same name, which could cause
980          problems if the linker chose the wrong constructor
981        - fixed low-level ConditionServer usage bug that caused lockups on
982          Windows
983    
984    
985    Version 0.5.1 (6 December 2007)
986    
987      * packaging changes:
988        - added autoconf checks for pthread library
989        - added autoconf check for pthread bug found on certain NPTL-enabled
990          glibc versions (see Gentoo bug report #194076)
991        - added autoconf checks for MS Windows
992    
993      * general changes:
994        - bugfix: the thread used by an editor plugin didn't die when the
995          editor closed
996        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
997          out all the space. operator--() did not apply size_mask after
998          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
999          order to avoid problems with the _NonVolatileReader functions.
1000        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1001          GetWriteSpace(). Since this function is currently only used in
1002          the stream's qsort() compare function, it didn't trigger any
1003          bugs.
1004        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1005          24bit mode too. Faster method to read 24bit words on little
1006          endian machines (x86): replaced 3 byte reads + shifts with a 1
1007          unaligned 32bit read and shift
1008        - experimental support for MS Windows (MIDI input via MME, AUDIO
1009          output via ASIO)
1010        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1011        - support for monitoring the total number of active disk streams
1012          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1013          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1014    
1015      * AUDIO driver:
1016        - added Windows ASIO low latency audio driver
1017    
1018      * MIDI driver:
1019        - added MME Windows MIDI driver
1020    
1021      * LSCP server:
1022        - added support for Windows style path / filenames, however with
1023          forward slash path separators instead of backslash
1024          (i.e. "C:/foo/bar.gig")
1025        - allow naughty liblscp to send non-string device parameters within
1026          apostrophes as well
1027        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1028          "LIST FILE INSTRUMENTS <file>" and
1029          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1030          about an arbitrary instrument file on the system where the sampler is
1031          running on
1032    
1033    Version 0.5.0 (15 October 2007)
1034    
1035      * packaging changes:
1036        - config.h is not going to be installed along with liblinuxsampler's
1037          API header files anymore
1038        - only the API relevant header (and source) files will be exported to
1039          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1040        - added completely new XCode project files for Mac OSX which is now
1041          capable to execute our autoconf environment, thus no need anymore
1042          to maintain the compile time configuration file (osx/version.h) for
1043          OSX manually (patch by Toshi Nagata)
1044        - fixed buggy boolean --enable-foo / --disable-foo configure script
1045          parameters
1046        - global.h now only covers global definitions that are needed for the
1047          C++ API header files, all implementation internal global definitions
1048          are now in global_private.h
1049        - atomic.h is not exposed to the C++ API anymore
1050        - no need to include config.h anymore for using LS's API header files
1051        - fixed warnings in API doc generation
1052

1084        - added support for escape sequences to the instruments database
1085        - added highly experimental support for on-the-fly instrument editing
1086          within the sampler's process (by using instrument editor plugins),
1087          you'll notice the new "Registered instrument editors:" message on
1088          startup, added a new LSCP command:
1089          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1090          to spawn a matching instrument editor for the instrument on the
1091          given sampler channel, the plugin path can be overridden at compile
1092          time with ./configure --enable-plugin-dir=/some/dir
1093        - added experimental code for synchronizing instrument editors hosted
1094          in the sampler's process to safely edit instruments while playing
1095          without a crash (hopefully) by either suspending single regions
1096          wherever possible or if unavoidable whole engine(s)
1097        - fixed several issues in fundamental "Thread" class: set scheduling
1098          policy and priority on thread level, set a minimum stack size for
1099          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1100          threads simply inherited properties of starting thread instead of
1101          setting their own policy and priority
1102        - minor fix in our automatic stack trace mechanism on crashes, the
1103          main process did not wait for the stack trace process to finish
1104          its output
1105        - fixed some minor memory leaks
1106        - reenabled assembly features support, at the moment only for
1107          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1108        - minor assembly fix in x86 features detection (don't use the PIC
1109          register, to avoid relocations in the text segment at runtime)
1110        - POSIX callback functions of Thread.h are hidden
1111    
1112    * MIDI driver:    * MIDI driver:
1113      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
1114    
1115      * audio driver:
1116        - the ALSA audio output driver parameters now reflect the correct
1117          parameter value ranges for the respective selected sound card
1118          (patch by Till Wimmer, a bit fixed and extended)
1119    
1120    * Gigasampler format engine:    * Gigasampler format engine:
1121      - if a filter is used and EG2 finishes before EG1, let the voice      - if a filter is used and EG2 finishes before EG1, let the voice
1122        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
1123        voice starvation for some gigs)        voice starvation for some gigs)
1124        - playback is no longer disabled during instrument loading
1125        - all notes playing on a channel that changes its instrument keep
1126          playing with the old instrument until they get a note off
1127          command
1128        - EG fix: a release value of zero could cause noises or crash
1129        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1130        - EG fine tuning: when attack is zero the EG starts at a level
1131          above max sustain level, which means that there is a decay phase
1132          even if sustain is 100%
1133        - more EG fixes: the level could sometimes go below zero and cause
1134          noises or crashes
1135        - minor fix of EGDecay (patch by Toshi Nagata)
1136        - fixed compiler error when --enable-override-filter-type was
1137          supplied to the configure script (fixes #46)
1138        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1139          instead of a fix value
1140        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1141          127 (solo mode) only kill voices if the respective mode really
1142          changed
1143    
1144      * LSCP server:
1145        - fixed compile time error for old Bison versions
1146          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1147        - parser now supports extended ASCII character set
1148          (up to ASCII code 255, i.e. includes now umlauts and accents)
1149        - filename arguments in LSCP commands now allow to use escape
1150          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1151          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1152          code value like \xf2) (fixes bug #24)
1153        - the following LSCP commands now also support escape sequences for at
1154          least one of their text-based parameters (i.e. name, description):
1155          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1156          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1157          "SET DB_INSTRUMENT_DIRECTORY NAME",
1158          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1159          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1160          "FIND DB_INSTRUMENT_DIRECTORIES"
1161        - returns verbose syntax errors (line and column where syntax error
1162          occured, the unexpected character and the actually expected, possible
1163          character(s), the latter only if less than 5 possibilities)
1164        - made sure that LSCP syntax is not affected by gigedit locale
1165          settings
1166        - bugfix regarding strings parameter lists: all comma separated lists
1167          of strings were treated as being one string containing commas
1168          (fixes #57)
1169    
1170    * Bug fixes:    * Bug fixes:
1171      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
1172        - another thread safety fix for lscp "load engine" and "set
1173          channel audio output device"
1174        - fixed a crash which occurs when reassigning the same engine
1175          on a sampler channel with connected MIDI device
1176        - fixed a crash which occurs when changing the number of ports of a MIDI
1177          device connected to a sampler channel to number less then or equal
1178          to the index of the port to which the sampler channel is connected.
1179        - The previous bindings were not been disconnected when altering
1180          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1181          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1182        - The active stream/voice count statistic was incorrect.
1183        - notification events were not been sent for some sampler
1184          channel changes
1185        - added default min and max values to restrict the number of allowed
1186          audio output channels and MIDI input ports
1187        - the connection to the PCM interface is now closed when destroying
1188          an audio output device
1189        - files with slash in their path or filename could not be loaded
1190    
1191      * test cases:
1192        - updated and fixed (haven't been touched in a while)
