# 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    
200      * Instruments DB:
201        - Fixed memory access bug of general DB access code which lead to
202          undefined behavior.
203        - Cleanup of instruments DB file creation and opening code.
204        - The instrument DB path of linuxsampler's --create-instruments-db argument
205          is now optional, if it is missing, then a default location is used.
206        - Added support for scanning SFZ (.sfz) files.
207        - Added support for scanning Sound Font (.sf2) files.
208        - Fixed undefined DB transaction behavior.

211    
212      * packaging changes:
213        - fixed building with newer MinGW-w64
214        - Mac OS X: support the new dir for Core Audio SDK
215        - Mac OS X: fixed building outside source directory
216        - made sure all source files for hostplugins are included when
217          doing "make dist"
218        - removed empty directories left from the cvs to svn migration
219        - fixed compilation with gcc 4.6.1
220        - another "make dist" fix, for the LV2 plugin
221        - made --enable-pthread-testcancel default on Mac OS X
222        - minor Makefile fix for building lscpparser when build and source
223          directories are separate
224        - Mac OS X: made it possible to specify plugin installation dir to
225          configure
226        - Mac OS X: Makefile fix for the install-strip target
227        - fixed compilation with gcc 4.7
228        - fixed configure script error with old autoconf versions
229        - lsatomic.h: use gcc provided atomic functions if building with
230          gcc 4.7 and C++11
231        - modernized configure script
232        - fixed linkage error when building with
233          LDFLAGS="-Wl,--no-undefined" (#190)
234        - fixed compilation with Clang 3.2
235        - removed usage of deprecated Automake variable INCLUDES
236        - fixed building with C++11
237        - build fix: ChangeFlagRelaxed.h was missing in makefile
238        - build fix: libsndfile compiler flags were missing in some
239          makefiles
240        - fix for building with bison 3.0 (#202)
241        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
242          on the process's main thread
243        - fixed build error on newer MinGW
244        - support building with older jack versions
245        - support building with spaces in vst sdk path
246        - enabled automake 'subdir-objects' option and moved external
247          source references (vst, au, asio) from makefiles to cpp files,
248          in order to get rid of warnings from automake 1.14
249    
250      * general changes:
251        - Refactoring: moved the independent code from
252          the Gigasampler format engine to base classes
253        - command line option '--profile' is currently disabled, since the
254          respective profiling code is currently broken
255        - Introduced support for optional environment variable
256          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
257          where the sampler shall look for instrument editor plugins
258          (patch by Luis Garrido, slightly modified).
259        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
260        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
261        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
262          note (in this implementation of the sampler its simply hard routed to
263          the 1st effect send of the sampler channel, no matter what the actual
264          effect type is)
265        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
266          note (in this implementation of the sampler its simply hard routed to
267          the 2nd effect send of the sampler channel, no matter what the actual
268          effect type is)
269        - implemented support for internal LADSPA effects
270        - raised limit of program change queue from 100 to 512
271          (as suggested by Alex Stone)
272        - implemented sine LFO, pulse LFO and saw LFO
273        - experimental support for per voice equalization
274        - added command line option --exec-after-init
275        - Introduced new C++ API method:
276          EngineChannel::InstrumentFileName(int index)
277          allowing to retrieve the whole list of files used for the loaded
278          instrument on an engine channel (a.k.a. part). Some GigaStudio
279          instruments for example are splitted over several files like
280          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
281        - Added new C++ API method Sampler::GetGlobalMaxVoices().
282        - Added new C++ API method Sampler::GetGlobalMaxStreams().
283        - Added new C++ API method Sampler::SetGlobalMaxVoices().
284        - Added new C++ API method Sampler::SetGlobalMaxStreams().
285        - Various "const" and "restrict" optimizations.
286        - all engines: add pan CC value to instrument pan parameter before
287          applying panning, instead of using two separate pan functions in
288          series (#182)
289        - added a lock guard class for exception safe mutex handling and
290          used it everywhere appropriate
291        - Immediately apply scale tuning changes to active voices.
292        - Exposed scale tuning to C++ API (along to the already existing standard
293          SysEx way).
294        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
295          and broken for ppc64. (Seq_cst loads and stores are actually not
296          used in LS, so the bug wasn't noticable.)
297        - lsatomic.h: added ARMv7 support
298        - Added support for multiple MIDI input ports per sampler channel (and
299          added various new C++ methods for this new feature / design change, old
300          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
301          as deprecated but are still there and should provide full behavior
302          backward compatibility).
303        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
304          unsafe and caused compilation error with clang 2.x).
305        - Bugfix: only process the latest MIDI program change event.
306        - Introducing the LSCP shell, which provides convenient control of the
307          sampler from the command line by providing LSCP aware features.
308        - VirtualMidiDevice: Added support for program change.
309        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
310        - VirtualMidiDevice: Added support for pitch bend.
311        - Aftertouch: extended API to explicitly handle channel pressure and
312          polyphonic key pressure events (so far polyphonic pressure was not
313          supported at all, and channel pressure was rerouted as CC128 but not
314          used so far).
315        - Added initial support for real-time instrument scripts. The script VM
316          code is shared by all sampler engine implemementations, however only the
317          gig file format currently provides support for storing instrument scripts
318          (as LinuxSampler extension to the original GigaStudio 4 format).
319    
320      * Gigasampler format engine:
321        - implemented the "round robin keyboard" dimension
322        - fixed round robin and random dimensions for cases when number of
323          dimension zones is not a power of two
324        - made round robin use a counter for each region instead of each
325          key
326        - bugfix: pitch LFO controller "internal+aftertouch" was broken
327        - bugfix: filter keyboard tracking was broken
328        - filter performance fix (an unnecessary copy was made of the
329          filter parameters in each sub fragment)
330        - handle special case when pan parameter in gig file has max or
331          min value
332        - Exclusive Groups: don't ever stop voices of the same note,
333          doesn't sound naturally with a drumkit
334        - fixed EG1 modulation when attack or release is zero
335        - Fixed support for 'aftertouch' attenuation controller.
336        - Fixed crash that happened with velocity split sounds under certain
337          conditions (see also previous commit on libgig).
338        - fixed behaviour of filter LFO
339    
340      * SFZ format engine:
341        - Initial implementation (not usable yet)
342        - added support for v2 multiple stage envelope generators
343        - added a fine-tuned v1 envelope generator instead of using the
344          one from the gig engine
345        - fixed memory leak and memory handling errors
346        - added support for trigger=first, trigger=legato and sw_previous
347        - allow non-numerical key values ("C#4" for example)
348        - "key" opcode now sets pitch_keycenter too
349        - fixed error when unloading instrument with same sample used by
350          multiple regions
351        - added some opcode aliases, like loopmode for loop_mode, to be
352          more compatible
353        - added support for trigger=release and rt_decay
354        - added support for off_mode=normal
355        - added support for random, seq_position, seq_length and volume
356        - added v1 LFO opcodes to parser (no support in engine yet)
357        - added support for amp_veltrack and amp_velcurve_N
358        - fine-tuned the default velocity curve
359        - added support for transpose
360        - fixed crash when using sw_down/up
361        - improved logic for sw_lokey/hikey/up/down/last
362        - added more v1 aliases to parser
363        - reduced memory usage for sfz data
364        - RT-safeness: avoid malloc in audio thread
365        - fixed a bug that could cause voice stealing to fail
366        - optimized sample lookup
367        - improved support for exclusive groups (group, off_by and
368          off_mode)
369        - added support for controller triggered regions (on_locc/on_hicc)
370        - added support for loop_mode=one_shot
371        - fixed playback of 16 bit wav files on big endian CPUs
372        - added support for Ogg Vorbis sample files
373        - use loop markers from sample file if loop_start and loop_end are

520        - save engine type (gig, sfz or sf2) in plugin state
521        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

577        - MME bugfix: driver wasn't closed properly
578        - CoreMIDI: automatically connect to all input sources by default (driver
579          parameter "AUTO_BIND").
580        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
581        - CoreMIDI: fixed minor memory leak
582    
583      * audio driver:

689        - Implemented built-in script function "delete_event_mark()".
690        - Implemented built-in script function "by_marks()".
691        - Added built-in script int const variables $MARK_1 to $MARK_28.
692        - Built-in script functions "ignore_event()", "note_off()" and
693          "gig_set_dim_zone()" now also accept an array of event IDs as argument
694          (i.e. return value of new script function "by_marks()").
695        - Pass/preserve polyphonic variable data from respective "note" event
696          handler to "release" event handler.
697        - Fixed crash when using built-in script function "by_marks()".
698    
699      * Bug fixes:
700        - Fixed crash which may occur when MIDI key + transpose is out of range
701        - minor valgrind fixes
702        - fixed crash which occurred when changing an already deployed sampler
703          channel to a different engine type
704        - fixed crash when deleting a sampler channel or changing engine
705          type while an instrument load was in progress
706        - bugfix: playing a note while changing the instrument could cause
707          a crash, or give "Handing back unknown region" error messages
708        - bugfix: calling SET VOICES (which Fantasia does on start and
709          refresh) could cause instruments to be unloaded
710        - Mac OS X: fixed name collision of enum in EffectControl and
711          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
712        - Mac OS X: fixed hanging threads
713        - Windows: disabled the previous thread fix on non-Mac systems, as
714          it caused hanging threads on Windows
715        - Fixed possible crashes due to corrupted MIDI/audio device list
716          after MIDI/audio device creation failure
717        - When creating MIDI instrument map entries with "PERSISTENT" type, the
718          instruments were uselessly precached with zero samples, however it still
719          took the full preloading time and on 1st program change the respective
720          instrument was completely reloaded again.
721        - fixed handling of rapid bank select and program change messages
722          sent to the same sampler channel (patch from the Open Octave
723          project, slightly adjusted)
724        - fixed crash when trying to create an effect instance with controls
725          which min and/or max values depend on the sample rate
726        - fixed bug #162
727        - bugfix: LADSPA_PATH was not evaluated correctly when containing
728          multiple paths (#165)
729        - thread safety fixes for the instrument loading thread
730        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
731          (#176)
732        - more thread safety fixes for the instrument loading thread
733        - sfz/sf2 engine: fixed crash when using small audio fragment size
734        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
735        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
736          introduced in previous fix)
737        - fixed crash when a channel received a program change while
738          playing a note in a key group
739        - fixed erroneous error message piping in VoiceBase.h
740          (labelled "Disk stream not available in time")
741        - Update effects on sample rate & period size changes (to avoid
742          crashes and noise on such transitions).
743        - ignore missing LADSPA paths without ignoring valid LADSPA paths
744          (fixes #208)
745        - Fixed bug in LSCP grammar definition which caused a statement like
746          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
747          practically irrelevant, however it caused problems with the new LSCP
748          shell's auto completion feature).
749        - Fixed MIDI program change messages being ignored if quickly executed
750          after each other (fixes #231).
751    
752    Version 1.0.0 (31 July 2009)
753    
754    * packaging changes:    * packaging changes:
755        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
756          causing e.g. the libgig test to fail when
757          "./configure --disable-jack-driver" was used
758          (patch by Alexis Ballier)
759        - fixed compilation with gcc 4.3
760        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
761        - fixed configure so it detects x86_64 (#107)
762        - fixes for building with newer MinGW versions
763        - fix for building with bison 2.4 (#111)
764        - fixed building with libgig installed in a non-standard directory
765        - minor fix in configure for mmsystem.h detection on MinGW
766        - Windows: look for editor plugins and Fantasia using base
767          directory of liblinuxsampler dll (look in the same directory and one
768          directory above)
769        - configure script fix: removed unconditional use of SSE
770        - fixed building with sqlite installed in a non-standard directory
771        - when cross-compiling, don't try to create instruments.db
772        - fix for new mingw-w64 version, which has usleep
773    
774      * general changes:
775        - bugfix: on some POSIX systems instrument editor plugins refused to
776          load as we used a non-portable Linux specific struct field
777          (fixes bug #70, patch by Ronald Baljeu)
778        - fixed endless loop which occured when loading an instrument editor
779          plugin DLL on Windows systems failed
780        - fixed memory leaks that occurred when liblinuxsampler was unloaded
781        - optimized the SynchronizedConfig class so it doesn't wait
782          unnecessarily long after an update
783        - added support for notifying instrument editors on note-on / note-off
784          events (e.g. to highlight the pressed keys on the virtual keyboard
785          of gigedit)
786        - added support for triggering notes by instrument editors (see above)
787        - be verbose on DLL load errors (on Linux)
788        - fixed di-harmonic triangle LFO implementation (this LFO implementation
789          is only used by very few systems, most pick the int math
790          implementation, which is usually faster)
791        - fixes for audio drivers with varying buffer sizes
792        - experimental support for running LinuxSampler as a DSSI, LV2 and
793          VST plugin
794        - notification events for stream/voice count statistics are now sent
795          only when there are actual changes
796        - added memory ordering constraints to improve stability on
797          multi-core and multi-cpu systems
798        - maximum voices and disk streams can now be altered at runtime
799        - fixed CPU feature detection on x86_64 (maybe fixes #108)
800        - automatic stacktrace mechanism is now turned off by default and can
801          be switched on by command line option "--stacktrace" (the automatic
802          stacktrace mechanism seems to be broken on most systems at the moment)
803        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
804          a pointer to the launched InstrumentEditor object
805        - added optional 3rd party user data parameter for following
806          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
807          InstrumentEditor::Launch(),
808          InstrumentManager::LaunchInstrumentEditor()
809        - theoretical fix: made SynchronizedConfig follow C++0x memory
810          model more strictly
811        - fixes for using large audio device buffers
812        - Windows: add the installation directory to the DLL search path
813          when loading an editor plugin (solves problems with VST and
814          gigedit on systems with other GTK versions installed)
815        - updated linuxsampler man page
816    
817      * audio driver:
818        - removed the nonsense audio channel constraint (which was hard coded to
819          max. 100 audio channels) for most audio drivers
820        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
821          opposed to the LSCP specs
822        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
823          reflected the wrong value
824        - fixed a memory management bug in ASIO driver
825        - Makefile fix: JACK_CFLAGS wasn't used
826        - JACK: use jack_client_open instead of the deprecated
827          jack_client_new
828        - added (experimental) CoreAudio driver
829        - applied old fixes to the ASIO driver that were included in the
830          previous binary release but accidentally never committed to CVS
831          (fixes #117)
832        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
833          win64)
834        - VST: added support for sample rate and buffer size changes
835        - VST: close editor (Fantasia) when the VST is removed
836        - VST: avoid opening Fantasia more than once for each VST instance
837        - VST: export main function as "main" on Linux too (fix for
838          energyXT)
839        - VST: changed number of output channels from one stereo to 16
840          stereo
841        - added channel routing, fxsends and midi maps to the settings
842          stored in the plugin state
843        - performance optimization of AudioChannel::MixTo() and
844          AudioChannel::CopyTo() methods using GCC vector exensions
845          (if available)
846        - ASIO fixes: avoid initializing the device twice, avoid throwing
847          exception when getting parameters from a disconnected device
848    
849      * MIDI driver:
850        - added JACK MIDI driver
851        - dispatch bank select as ordinary CC as well, the user might seriously
852          want to (mis)use it for some purpose ("fixed" in all current MIDI
853          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
854        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
855          CoreMidi or AU
856        - fixed mingw-w64 compilation error in MME driver
857        - made program change handling in MIDI thread real-time safe by
858          moving the logic to a non-RT thread
859        - fixed minor memory leak in ALSA driver
860    
861      * instruments database:
862        - avoid time consuming samples scanning when adding instruments
863          to the instruments database
864        - added support for handling lost files in the instruments database
865        - Implemented option for adding instruments in separate directories
866          in the instruments database
867          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
868        - work-around for missing fnmatch function on Windows to make
869          instrument database compilable
870        - added instrument database support on Windows
871          works with both standalone mode and VST plugin.
872          the instruments DB file is located in
873          %USERPROFILE%\.linuxsampler\instruments.db which allows different
874          databases for each windows user
875          if no DB is present it automatically creates the .linuxsampler subdir
876          and then creates an empty DB
877        - fixed recursive import, which was broken on Windows
878    
879      * Gigasampler format engine:
880        - fixed a memory leak that could happen when a channel was deleted
881          while notes were playing
882        - made it possible to load an instrument even if the audio thread
883          isn't running
884        - added partial support for the "Controller Triggered" MIDI rule,
885          enough for piano gigs with pedal noise samples
886        - minor fix: only mark FX sends as being modified if really the
887          respective FX send MIDI controller was used
888        - added support for GM global device volume SysEx message
889          (can be selected at compile time to either apply globally to the
890          whole sampler [default] or only to the sampler channels that are
891          connected to the respective MIDI input port the SysEx message arrived
892          on)
893        - bugfix: notes triggered at position 0 in the audio buffer were
894          sometimes wrongly killed in the same buffer, causing no sound to
895          be played
896        - added support for chromatic / drumkit mode Roland GS Sysex message
897          which is usally used to switch a part between chromatic sounds and
898          drumkit sounds (as opposed to their common default setting of MIDI
899          part 10 being a drumkit part and all other ones chromatic parts), in
900          LS however one can switch between the first 16 MIDI instrument maps
901          defined for the sampler
902        - made it possible to create multiple sample channels even if the
903          audio thread isn't running
904        - fixed crash when removing channel with active voices (#116)
905        - bugfix: on sample reference changes (instrument editor), only
906          un-cache the respective sample if it's really not used by any
907          sampler engine anymore
908        - re-cache samples in case they were changed by an instrument editor,
909          e.g. when a sample was added while playing (#82)
910        - fixed hanging notes which occured when note-off event had the exact
911          same time stamp as the voice's note-on event and occured both in the
912          same audio fragment cycle (fixes bug #112)
913        - added support for the "fine tune" and "pitch bend range"
914          instrument-level gig parameters
915        - fixed minor artifacts in pitch bend handling
916        - added support for GS Reset SysEx message
917        - allow gig files to use unlimited downward pitch shifting
918        - added a limit check for upward pitch shifting
919        - bugfix: sometimes, when playing a note twice fast, the second
920          note was silent
921        - fixed crash happening when a pitch bend event arrived at the
922          same time a new instrument was loading
923    
924      * LSCP server:
925        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
926          react on MIDI data arriving on certain sampler channels (so far only
927          Note-On and Note-Off events are sent via this LSCP event)
928        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
929          react on MIDI data arriving on certain MIDI input devices (so far only
930          Note-On and Note-Off events are sent via this LSCP event)
931        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
932          SET DB_INSTRUMENT FILE_PATH
933        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
934          frontends to send MIDI messages to specific sampler channel
935        - added two additional fields to GET FILE INSTRUMENT INFO command -
936          KEY_BINDINGS and KEYSWITCH_BINDINGS
937        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
938          was incorrect
939        - Optimized the retrieval of the MIDI instrument mappings
940        - added new LSCP command "SET VOICES" to globally alter the maximum
941          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
942          be triggered respectively
943        - added new LSCP command "SET STREAMS" to globally alter the maximum
944          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
945          which will be triggered respectively
946        - bugfix: retry if "select" returns EINTR (this fixes a crash when
947          a gigedit file dialog is opened)
948        - close all connections when LSCPServer is deleted
949        - hard close of all sockets on exit
950        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
951          driver
952    
953      * Bug fixes:
954        - fixed a crash which occurs when removing a sampler channel waiting
955          to start instrument loading after another channel
956        - fixed a crash which occurs when removing a sampler channel with
957          instrument loading in progress (bug #113)
958        - fixed termination caused by uncaught exception when adding MIDI
959          instrument with PERSISTENT load mode
960        - fixed possible iterator invalidations when resetting the sampler
961        - fixed memory leaks when issuing the following LSCP commands:
962          GET AUDIO_OUTPUT_DRIVER INFO
963          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
964          GET MIDI_INPUT_DRIVER INFO
965          GET MIDI_INPUT_DRIVER_PARAMETER INFO
966        - fixed possible compilation error when sqlite is not present
967        - fixed orphaned pointers when setting maximum voices limit (bug #118)
968        - fixed crash when changing the audio output device of a sampler
969          channel with loaded instrument and start playing notes
970        - fixed endless loop in Engine::SuspendAll() (bug #120)
971        - fixed a low-level atomic load function that was broken on 64-bit
972          PowerPC, which probably could cause crashes on that platform
973        - fixed a memory management error which could cause a crash when a
974          plugin was unloaded
975        - bugfix: two private structs had the same name, which could cause
976          problems if the linker chose the wrong constructor
977        - fixed low-level ConditionServer usage bug that caused lockups on
978          Windows
979    
980    
981    Version 0.5.1 (6 December 2007)
982    
983      * packaging changes:
984        - added autoconf checks for pthread library
985        - added autoconf check for pthread bug found on certain NPTL-enabled
986          glibc versions (see Gentoo bug report #194076)
987        - added autoconf checks for MS Windows
988    
989      * general changes:
990        - bugfix: the thread used by an editor plugin didn't die when the
991          editor closed
992        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
993          out all the space. operator--() did not apply size_mask after
994          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
995          order to avoid problems with the _NonVolatileReader functions.
996        - bugfix: Stream.h: added a missing divide by BytesPerSample in
997          GetWriteSpace(). Since this function is currently only used in
998          the stream's qsort() compare function, it didn't trigger any
999          bugs.
1000        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1001          24bit mode too. Faster method to read 24bit words on little
1002          endian machines (x86): replaced 3 byte reads + shifts with a 1
1003          unaligned 32bit read and shift
1004        - experimental support for MS Windows (MIDI input via MME, AUDIO
1005          output via ASIO)
1006        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1007        - support for monitoring the total number of active disk streams
1008          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1009          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1010    
1011      * AUDIO driver:
1012        - added Windows ASIO low latency audio driver
1013    
1014      * MIDI driver:
1015        - added MME Windows MIDI driver
1016    
1017      * LSCP server:
1018        - added support for Windows style path / filenames, however with
1019          forward slash path separators instead of backslash
1020          (i.e. "C:/foo/bar.gig")
1021        - allow naughty liblscp to send non-string device parameters within
1022          apostrophes as well
1023        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1024          "LIST FILE INSTRUMENTS <file>" and
1025          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1026          about an arbitrary instrument file on the system where the sampler is
1027          running on
1028    
1029    Version 0.5.0 (15 October 2007)
1030    
1031      * packaging changes:
1032        - config.h is not going to be installed along with liblinuxsampler's
1033          API header files anymore
1034        - only the API relevant header (and source) files will be exported to
1035          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1036        - added completely new XCode project files for Mac OSX which is now
1037          capable to execute our autoconf environment, thus no need anymore
1038          to maintain the compile time configuration file (osx/version.h) for
1039          OSX manually (patch by Toshi Nagata)
1040        - fixed buggy boolean --enable-foo / --disable-foo configure script
1041          parameters
1042        - global.h now only covers global definitions that are needed for the
1043          C++ API header files, all implementation internal global definitions
1044          are now in global_private.h
1045        - atomic.h is not exposed to the C++ API anymore
1046        - no need to include config.h anymore for using LS's API header files
1047        - fixed warnings in API doc generation
1048    
1049      * general changes:
1050        - replaced the old, confusing MIDI program change mechanism by a
1051          flexible MIDI instrument mapper which allows to map arbitrary
1052          (MIDI bank, MIDI program) pairs with arbitrary
1053          (engine type, instrument file, file index) triplets which will be
1054          loaded on the respective channel when such MIDI program change
1055          messages arrive, beside that, each entry allows to define a life-time
1056          strategy for the instrument, so the user can define whether the
1057          instrument should i.e. be permanently loaded (to be able to switch
1058          quickly among sounds) or i.e. loaded just on demand when the
1059          respective program change arrives (to safe RAM space), as well as a
1060          global volume factor for each entry, so the user can adjust the volume
1061          dynamic of his mapped instrument collection without having to modify
1062          the instrument files, also one can manage arbitrary amount of such
1063          MIDI instrument maps and assign each sampler channel individually
1064          a certain map, so that i.e. separation of normal instruments and
1065          drumkits is possible
1066        - new notification events for tracking changes to audio/MIDI devices,
1067          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1068        - sampler was limited to load max. 200 instruments in the background
1069          due to a constant size RingBuffer FIFO which is now replaced by a
1070          dynamic (unlimited) size std::list FIFO
1071        - added FX sends, these allow to route audio signals to arbitrary audio
1072          output channels for being processed by external effect processors
1073          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1074          controllers
1075        - global (sampler wide) volume can now be controlled at runtime
1076        - Implemented new, improved notification system
1077        - fixed compilation errors regarding OSX
1078          (patch by Toshi Nagata)
1079        - implemented instruments database
1080        - added support for escape sequences to the instruments database
1081        - added highly experimental support for on-the-fly instrument editing
1082          within the sampler's process (by using instrument editor plugins),
1083          you'll notice the new "Registered instrument editors:" message on
1084          startup, added a new LSCP command:
1085          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1086          to spawn a matching instrument editor for the instrument on the
1087          given sampler channel, the plugin path can be overridden at compile
1088          time with ./configure --enable-plugin-dir=/some/dir
1089        - added experimental code for synchronizing instrument editors hosted
1090          in the sampler's process to safely edit instruments while playing
1091          without a crash (hopefully) by either suspending single regions
1092          wherever possible or if unavoidable whole engine(s)
1093        - fixed several issues in fundamental "Thread" class: set scheduling
1094          policy and priority on thread level, set a minimum stack size for
1095          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1096          threads simply inherited properties of starting thread instead of
1097          setting their own policy and priority
1098        - minor fix in our automatic stack trace mechanism on crashes, the
1099          main process did not wait for the stack trace process to finish
1100          its output
1101        - fixed some minor memory leaks
1102        - reenabled assembly features support, at the moment only for
1103          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1104        - minor assembly fix in x86 features detection (don't use the PIC
1105          register, to avoid relocations in the text segment at runtime)
1106        - POSIX callback functions of Thread.h are hidden
1107    
1108      * MIDI driver:
1109        - dispatch bank select (MSB and LSB) messages
1110    
1111      * audio driver:
1112        - the ALSA audio output driver parameters now reflect the correct
1113          parameter value ranges for the respective selected sound card
1114          (patch by Till Wimmer, a bit fixed and extended)
1115    
1116      * Gigasampler format engine:
1117        - if a filter is used and EG2 finishes before EG1, let the voice
1118          die when EG2 has finished (this fixes a problem with clicks and
1119          voice starvation for some gigs)
1120        - playback is no longer disabled during instrument loading
1121        - all notes playing on a channel that changes its instrument keep
1122          playing with the old instrument until they get a note off
1123          command
1124        - EG fix: a release value of zero could cause noises or crash
1125        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1126        - EG fine tuning: when attack is zero the EG starts at a level
1127          above max sustain level, which means that there is a decay phase
1128          even if sustain is 100%
1129        - more EG fixes: the level could sometimes go below zero and cause
1130          noises or crashes
1131        - minor fix of EGDecay (patch by Toshi Nagata)
1132        - fixed compiler error when --enable-override-filter-type was
1133          supplied to the configure script (fixes #46)
1134        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1135          instead of a fix value
1136        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1137          127 (solo mode) only kill voices if the respective mode really
1138          changed
1139    
1140      * LSCP server:
1141        - fixed compile time error for old Bison versions
1142          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1143        - parser now supports extended ASCII character set
1144          (up to ASCII code 255, i.e. includes now umlauts and accents)
1145        - filename arguments in LSCP commands now allow to use escape
1146          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1147          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1148          code value like \xf2) (fixes bug #24)
1149        - the following LSCP commands now also support escape sequences for at
1150          least one of their text-based parameters (i.e. name, description):
1151          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1152          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1153          "SET DB_INSTRUMENT_DIRECTORY NAME",
1154          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1155          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1156          "FIND DB_INSTRUMENT_DIRECTORIES"
1157        - returns verbose syntax errors (line and column where syntax error
1158          occured, the unexpected character and the actually expected, possible
1159          character(s), the latter only if less than 5 possibilities)
1160        - made sure that LSCP syntax is not affected by gigedit locale
1161          settings
1162        - bugfix regarding strings parameter lists: all comma separated lists
1163          of strings were treated as being one string containing commas
1164          (fixes #57)
1165    
1166      * Bug fixes:
1167        - fixed crash occurring on certain LSCP scripts (Bug 39)
1168        - another thread safety fix for lscp "load engine" and "set
1169          channel audio output device"
1170        - fixed a crash which occurs when reassigning the same engine
1171          on a sampler channel with connected MIDI device
1172        - fixed a crash which occurs when changing the number of ports of a MIDI
1173          device connected to a sampler channel to number less then or equal
1174          to the index of the port to which the sampler channel is connected.
1175        - The previous bindings were not been disconnected when altering
1176          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1177          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1178        - The active stream/voice count statistic was incorrect.
1179        - notification events were not been sent for some sampler
1180          channel changes
1181        - added default min and max values to restrict the number of allowed
1182          audio output channels and MIDI input ports
1183        - the connection to the PCM interface is now closed when destroying
1184          an audio output device
1185        - files with slash in their path or filename could not be loaded
1186    
1187      * test cases:
1188        - updated and fixed (haven't been touched in a while)
1189

1192      * packaging changes:
1193        - changed deprecated copyright attribute to license; added ldconfig
1194          to post-(un)install steps; added devel package for liblinuxsampler;
1195          to linuxsampler.spec (RPM)
