# 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".

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    
188      * Instruments DB:
189        - Fixed memory access bug of general DB access code which lead to
190          undefined behavior.
191        - Cleanup of instruments DB file creation and opening code.
192        - The instrument DB path of linuxsampler's --create-instruments-db argument
193          is now optional, if it is missing, then a default location is used.
194        - Added support for scanning SFZ (.sfz) files.
195        - Added support for scanning Sound Font (.sf2) files.
196        - Fixed undefined DB transaction behavior.
197

205          doing "make dist"
206        - removed empty directories left from the cvs to svn migration
207        - fixed compilation with gcc 4.6.1
208        - another "make dist" fix, for the LV2 plugin
209        - made --enable-pthread-testcancel default on Mac OS X
210        - minor Makefile fix for building lscpparser when build and source
211          directories are separate
212        - Mac OS X: made it possible to specify plugin installation dir to
213          configure
214        - Mac OS X: Makefile fix for the install-strip target
215        - fixed compilation with gcc 4.7
216        - fixed configure script error with old autoconf versions

231        - fixed build error on newer MinGW
232        - support building with older jack versions
233        - support building with spaces in vst sdk path
234        - enabled automake 'subdir-objects' option and moved external
235          source references (vst, au, asio) from makefiles to cpp files,
236          in order to get rid of warnings from automake 1.14
237    
238      * general changes:
239        - Refactoring: moved the independent code from
240          the Gigasampler format engine to base classes
241        - command line option '--profile' is currently disabled, since the
242          respective profiling code is currently broken
243        - Introduced support for optional environment variable
244          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
245          where the sampler shall look for instrument editor plugins
246          (patch by Luis Garrido, slightly modified).
247        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
248        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
249        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
250          note (in this implementation of the sampler its simply hard routed to
251          the 1st effect send of the sampler channel, no matter what the actual
252          effect type is)
253        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
254          note (in this implementation of the sampler its simply hard routed to
255          the 2nd effect send of the sampler channel, no matter what the actual
256          effect type is)
257        - implemented support for internal LADSPA effects
258        - raised limit of program change queue from 100 to 512
259          (as suggested by Alex Stone)
260        - implemented sine LFO, pulse LFO and saw LFO
261        - experimental support for per voice equalization
262        - added command line option --exec-after-init
263        - Introduced new C++ API method:
264          EngineChannel::InstrumentFileName(int index)
265          allowing to retrieve the whole list of files used for the loaded
266          instrument on an engine channel (a.k.a. part). Some GigaStudio
267          instruments for example are splitted over several files like
268          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
269        - Added new C++ API method Sampler::GetGlobalMaxVoices().
270        - Added new C++ API method Sampler::GetGlobalMaxStreams().
271        - Added new C++ API method Sampler::SetGlobalMaxVoices().
272        - Added new C++ API method Sampler::SetGlobalMaxStreams().
273        - Various "const" and "restrict" optimizations.
274        - all engines: add pan CC value to instrument pan parameter before
275          applying panning, instead of using two separate pan functions in
276          series (#182)
277        - added a lock guard class for exception safe mutex handling and
278          used it everywhere appropriate
279        - Immediately apply scale tuning changes to active voices.
280        - Exposed scale tuning to C++ API (along to the already existing standard
281          SysEx way).
282        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
283          and broken for ppc64. (Seq_cst loads and stores are actually not
284          used in LS, so the bug wasn't noticable.)
285        - lsatomic.h: added ARMv7 support
286        - Added support for multiple MIDI input ports per sampler channel (and
287          added various new C++ methods for this new feature / design change, old
288          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
289          as deprecated but are still there and should provide full behavior
290          backward compatibility).
291        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
292          unsafe and caused compilation error with clang 2.x).
293        - Bugfix: only process the latest MIDI program change event.
294        - Introducing the LSCP shell, which provides convenient control of the
295          sampler from the command line by providing LSCP aware features.
296        - VirtualMidiDevice: Added support for program change.
297        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
298        - VirtualMidiDevice: Added support for pitch bend.
299        - Aftertouch: extended API to explicitly handle channel pressure and
300          polyphonic key pressure events (so far polyphonic pressure was not
301          supported at all, and channel pressure was rerouted as CC128 but not
302          used so far).
303        - Added initial support for real-time instrument scripts. The script VM
304          code is shared by all sampler engine implemementations, however only the
305          gig file format currently provides support for storing instrument scripts
306          (as LinuxSampler extension to the original GigaStudio 4 format).
307    
308      * Gigasampler format engine:
309        - implemented the "round robin keyboard" dimension
310        - fixed round robin and random dimensions for cases when number of
311          dimension zones is not a power of two
312        - made round robin use a counter for each region instead of each
313          key
314        - bugfix: pitch LFO controller "internal+aftertouch" was broken
315        - bugfix: filter keyboard tracking was broken
316        - filter performance fix (an unnecessary copy was made of the
317          filter parameters in each sub fragment)
318        - handle special case when pan parameter in gig file has max or
319          min value
320        - Exclusive Groups: don't ever stop voices of the same note,
321          doesn't sound naturally with a drumkit
322        - fixed EG1 modulation when attack or release is zero
323        - Fixed support for 'aftertouch' attenuation controller.
324        - Fixed crash that happened with velocity split sounds under certain
325          conditions (see also previous commit on libgig).
326        - fixed behaviour of filter LFO
327    
328      * SFZ format engine:
329        - Initial implementation (not usable yet)
330        - added support for v2 multiple stage envelope generators
331        - added a fine-tuned v1 envelope generator instead of using the
332          one from the gig engine
333        - fixed memory leak and memory handling errors
334        - added support for trigger=first, trigger=legato and sw_previous
335        - allow non-numerical key values ("C#4" for example)
336        - "key" opcode now sets pitch_keycenter too
337        - fixed error when unloading instrument with same sample used by
338          multiple regions
339        - added some opcode aliases, like loopmode for loop_mode, to be
340          more compatible
341        - added support for trigger=release and rt_decay
342        - added support for off_mode=normal
343        - added support for random, seq_position, seq_length and volume
344        - added v1 LFO opcodes to parser (no support in engine yet)
345        - added support for amp_veltrack and amp_velcurve_N
346        - fine-tuned the default velocity curve
347        - added support for transpose
348        - fixed crash when using sw_down/up
349        - improved logic for sw_lokey/hikey/up/down/last
350        - added more v1 aliases to parser
351        - reduced memory usage for sfz data
352        - RT-safeness: avoid malloc in audio thread
353        - fixed a bug that could cause voice stealing to fail
354        - optimized sample lookup
355        - improved support for exclusive groups (group, off_by and
356          off_mode)
357        - added support for controller triggered regions (on_locc/on_hicc)
358        - added support for loop_mode=one_shot
359        - fixed playback of 16 bit wav files on big endian CPUs
360        - added support for Ogg Vorbis sample files
361        - use loop markers from sample file if loop_start and loop_end are
362          not set in sfz file
363        - implemeted filters. Filter types: lowpass, bandpass, bandreject
364          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
365          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
366          cutoff_cc, cutoff_chanaft.
367        - bugfix: zero ampeg_sustain didn't work
368        - added support for velocity effect on amplifier envelope time
369          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
370          ampeg_vel2release)
371        - added support for EG hold (ampeg_hold)
372        - added support for sample offset (offset)
373        - use the newly introduced signal units model
374        - implemented opcodes lfoN_delay,

507          incorrectly set to two. This caused silence in Cubase 5.
508        - save engine type (gig, sfz or sf2) in plugin state
509        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
510          64 bit Windows

565        - MME bugfix: driver wasn't closed properly
566        - CoreMIDI: automatically connect to all input sources by default (driver
567          parameter "AUTO_BIND").
568        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
569        - CoreMIDI: fixed minor memory leak
570    
571      * audio driver:

691          channel to a different engine type
692        - fixed crash when deleting a sampler channel or changing engine
693          type while an instrument load was in progress
694        - bugfix: playing a note while changing the instrument could cause
695          a crash, or give "Handing back unknown region" error messages
696        - bugfix: calling SET VOICES (which Fantasia does on start and
697          refresh) could cause instruments to be unloaded
698        - Mac OS X: fixed name collision of enum in EffectControl and
699          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
700        - Mac OS X: fixed hanging threads
701        - Windows: disabled the previous thread fix on non-Mac systems, as
702          it caused hanging threads on Windows
703        - Fixed possible crashes due to corrupted MIDI/audio device list
704          after MIDI/audio device creation failure
705        - When creating MIDI instrument map entries with "PERSISTENT" type, the
706          instruments were uselessly precached with zero samples, however it still
707          took the full preloading time and on 1st program change the respective
708          instrument was completely reloaded again.
709        - fixed handling of rapid bank select and program change messages
710          sent to the same sampler channel (patch from the Open Octave
711          project, slightly adjusted)
712        - fixed crash when trying to create an effect instance with controls
713          which min and/or max values depend on the sample rate
714        - fixed bug #162
715        - bugfix: LADSPA_PATH was not evaluated correctly when containing
716          multiple paths (#165)
717        - thread safety fixes for the instrument loading thread
718        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
719          (#176)
720        - more thread safety fixes for the instrument loading thread
721        - sfz/sf2 engine: fixed crash when using small audio fragment size
722        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
723        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
724          introduced in previous fix)
725        - fixed crash when a channel received a program change while
726          playing a note in a key group
727        - fixed erroneous error message piping in VoiceBase.h
728          (labelled "Disk stream not available in time")
729        - Update effects on sample rate & period size changes (to avoid
730          crashes and noise on such transitions).
731        - ignore missing LADSPA paths without ignoring valid LADSPA paths
732          (fixes #208)
733        - Fixed bug in LSCP grammar definition which caused a statement like
734          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
735          practically irrelevant, however it caused problems with the new LSCP
736          shell's auto completion feature).
737        - Fixed MIDI program change messages being ignored if quickly executed
738          after each other (fixes #231).
739    
740    Version 1.0.0 (31 July 2009)
741    
742      * packaging changes:
743        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
744          causing e.g. the libgig test to fail when
745          "./configure --disable-jack-driver" was used
746          (patch by Alexis Ballier)
747        - fixed compilation with gcc 4.3
748        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
749        - fixed configure so it detects x86_64 (#107)
750        - fixes for building with newer MinGW versions
751        - fix for building with bison 2.4 (#111)
752        - fixed building with libgig installed in a non-standard directory
753        - minor fix in configure for mmsystem.h detection on MinGW
754        - Windows: look for editor plugins and Fantasia using base
755          directory of liblinuxsampler dll (look in the same directory and one
756          directory above)
757        - configure script fix: removed unconditional use of SSE
758        - fixed building with sqlite installed in a non-standard directory
759        - when cross-compiling, don't try to create instruments.db
760        - fix for new mingw-w64 version, which has usleep
761    
762      * general changes:
763        - bugfix: on some POSIX systems instrument editor plugins refused to
764          load as we used a non-portable Linux specific struct field
765          (fixes bug #70, patch by Ronald Baljeu)
766        - fixed endless loop which occured when loading an instrument editor
767          plugin DLL on Windows systems failed
768        - fixed memory leaks that occurred when liblinuxsampler was unloaded
769        - optimized the SynchronizedConfig class so it doesn't wait
770          unnecessarily long after an update
771        - added support for notifying instrument editors on note-on / note-off
772          events (e.g. to highlight the pressed keys on the virtual keyboard
773          of gigedit)
774        - added support for triggering notes by instrument editors (see above)
775        - be verbose on DLL load errors (on Linux)
776        - fixed di-harmonic triangle LFO implementation (this LFO implementation
777          is only used by very few systems, most pick the int math
778          implementation, which is usually faster)
779        - fixes for audio drivers with varying buffer sizes
780        - experimental support for running LinuxSampler as a DSSI, LV2 and
781          VST plugin
782        - notification events for stream/voice count statistics are now sent
783          only when there are actual changes
784        - added memory ordering constraints to improve stability on
785          multi-core and multi-cpu systems
786        - maximum voices and disk streams can now be altered at runtime
787        - fixed CPU feature detection on x86_64 (maybe fixes #108)
788        - automatic stacktrace mechanism is now turned off by default and can
789          be switched on by command line option "--stacktrace" (the automatic
790          stacktrace mechanism seems to be broken on most systems at the moment)
791        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
792          a pointer to the launched InstrumentEditor object
793        - added optional 3rd party user data parameter for following
794          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
795          InstrumentEditor::Launch(),
796          InstrumentManager::LaunchInstrumentEditor()
797        - theoretical fix: made SynchronizedConfig follow C++0x memory
798          model more strictly
799        - fixes for using large audio device buffers
800        - Windows: add the installation directory to the DLL search path
801          when loading an editor plugin (solves problems with VST and
802          gigedit on systems with other GTK versions installed)
803        - updated linuxsampler man page
804    
805      * audio driver:
806        - removed the nonsense audio channel constraint (which was hard coded to
807          max. 100 audio channels) for most audio drivers
808        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
809          opposed to the LSCP specs
810        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
811          reflected the wrong value
812        - fixed a memory management bug in ASIO driver
813        - Makefile fix: JACK_CFLAGS wasn't used
814        - JACK: use jack_client_open instead of the deprecated
815          jack_client_new
816        - added (experimental) CoreAudio driver
817        - applied old fixes to the ASIO driver that were included in the
818          previous binary release but accidentally never committed to CVS
819          (fixes #117)
820        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
821          win64)
822        - VST: added support for sample rate and buffer size changes
823        - VST: close editor (Fantasia) when the VST is removed
824        - VST: avoid opening Fantasia more than once for each VST instance
825        - VST: export main function as "main" on Linux too (fix for
826          energyXT)
827        - VST: changed number of output channels from one stereo to 16
828          stereo
829        - added channel routing, fxsends and midi maps to the settings
830          stored in the plugin state
831        - performance optimization of AudioChannel::MixTo() and
832          AudioChannel::CopyTo() methods using GCC vector exensions
833          (if available)
834        - ASIO fixes: avoid initializing the device twice, avoid throwing
835          exception when getting parameters from a disconnected device
836    
837      * MIDI driver:
838        - added JACK MIDI driver
839        - dispatch bank select as ordinary CC as well, the user might seriously
840          want to (mis)use it for some purpose ("fixed" in all current MIDI
841          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
842        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
843          CoreMidi or AU
844        - fixed mingw-w64 compilation error in MME driver
845        - made program change handling in MIDI thread real-time safe by
846          moving the logic to a non-RT thread
847        - fixed minor memory leak in ALSA driver
848    
849      * instruments database:
850        - avoid time consuming samples scanning when adding instruments
851          to the instruments database
852        - added support for handling lost files in the instruments database
853        - Implemented option for adding instruments in separate directories
854          in the instruments database
855          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
856        - work-around for missing fnmatch function on Windows to make
857          instrument database compilable
858        - added instrument database support on Windows
859          works with both standalone mode and VST plugin.
860          the instruments DB file is located in
861          %USERPROFILE%\.linuxsampler\instruments.db which allows different
862          databases for each windows user
863          if no DB is present it automatically creates the .linuxsampler subdir
864          and then creates an empty DB
865        - fixed recursive import, which was broken on Windows
866    
867      * Gigasampler format engine:
868        - fixed a memory leak that could happen when a channel was deleted
869          while notes were playing
870        - made it possible to load an instrument even if the audio thread
871          isn't running
872        - added partial support for the "Controller Triggered" MIDI rule,
873          enough for piano gigs with pedal noise samples
874        - minor fix: only mark FX sends as being modified if really the
875          respective FX send MIDI controller was used
876        - added support for GM global device volume SysEx message
877          (can be selected at compile time to either apply globally to the
878          whole sampler [default] or only to the sampler channels that are
879          connected to the respective MIDI input port the SysEx message arrived
880          on)
881        - bugfix: notes triggered at position 0 in the audio buffer were
882          sometimes wrongly killed in the same buffer, causing no sound to
883          be played
884        - added support for chromatic / drumkit mode Roland GS Sysex message
885          which is usally used to switch a part between chromatic sounds and
886          drumkit sounds (as opposed to their common default setting of MIDI
887          part 10 being a drumkit part and all other ones chromatic parts), in
888          LS however one can switch between the first 16 MIDI instrument maps
889          defined for the sampler
890        - made it possible to create multiple sample channels even if the
891          audio thread isn't running
892        - fixed crash when removing channel with active voices (#116)
893        - bugfix: on sample reference changes (instrument editor), only
894          un-cache the respective sample if it's really not used by any
895          sampler engine anymore
896        - re-cache samples in case they were changed by an instrument editor,
897          e.g. when a sample was added while playing (#82)
898        - fixed hanging notes which occured when note-off event had the exact
899          same time stamp as the voice's note-on event and occured both in the
900          same audio fragment cycle (fixes bug #112)
901        - added support for the "fine tune" and "pitch bend range"
902          instrument-level gig parameters
903        - fixed minor artifacts in pitch bend handling
904        - added support for GS Reset SysEx message
905        - allow gig files to use unlimited downward pitch shifting
906        - added a limit check for upward pitch shifting
907        - bugfix: sometimes, when playing a note twice fast, the second
908          note was silent
909        - fixed crash happening when a pitch bend event arrived at the
910          same time a new instrument was loading
911    
912      * LSCP server:
913        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
914          react on MIDI data arriving on certain sampler channels (so far only
915          Note-On and Note-Off events are sent via this LSCP event)
916        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
917          react on MIDI data arriving on certain MIDI input devices (so far only
918          Note-On and Note-Off events are sent via this LSCP event)
919        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
920          SET DB_INSTRUMENT FILE_PATH
921        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
922          frontends to send MIDI messages to specific sampler channel
923        - added two additional fields to GET FILE INSTRUMENT INFO command -
924          KEY_BINDINGS and KEYSWITCH_BINDINGS
925        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
926          was incorrect
927        - Optimized the retrieval of the MIDI instrument mappings
928        - added new LSCP command "SET VOICES" to globally alter the maximum
929          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
930          be triggered respectively
931        - added new LSCP command "SET STREAMS" to globally alter the maximum
932          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
933          which will be triggered respectively
934        - bugfix: retry if "select" returns EINTR (this fixes a crash when
935          a gigedit file dialog is opened)
936        - close all connections when LSCPServer is deleted
937        - hard close of all sockets on exit
938        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
939          driver
940    
941      * Bug fixes:
942        - fixed a crash which occurs when removing a sampler channel waiting
943          to start instrument loading after another channel
944        - fixed a crash which occurs when removing a sampler channel with
945          instrument loading in progress (bug #113)
946        - fixed termination caused by uncaught exception when adding MIDI
947          instrument with PERSISTENT load mode
948        - fixed possible iterator invalidations when resetting the sampler
949        - fixed memory leaks when issuing the following LSCP commands:
950          GET AUDIO_OUTPUT_DRIVER INFO
951          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
952          GET MIDI_INPUT_DRIVER INFO
953          GET MIDI_INPUT_DRIVER_PARAMETER INFO
954        - fixed possible compilation error when sqlite is not present
955        - fixed orphaned pointers when setting maximum voices limit (bug #118)
956        - fixed crash when changing the audio output device of a sampler
957          channel with loaded instrument and start playing notes
958        - fixed endless loop in Engine::SuspendAll() (bug #120)
959        - fixed a low-level atomic load function that was broken on 64-bit
960          PowerPC, which probably could cause crashes on that platform
961        - fixed a memory management error which could cause a crash when a
962          plugin was unloaded
963        - bugfix: two private structs had the same name, which could cause
964          problems if the linker chose the wrong constructor
965        - fixed low-level ConditionServer usage bug that caused lockups on
966          Windows
967    
968    
969    Version 0.5.1 (6 December 2007)
970    
971      * packaging changes:
972        - added autoconf checks for pthread library
973        - added autoconf check for pthread bug found on certain NPTL-enabled
974          glibc versions (see Gentoo bug report #194076)
975        - added autoconf checks for MS Windows
976    
977      * general changes:
978        - bugfix: the thread used by an editor plugin didn't die when the
979          editor closed
980        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
981          out all the space. operator--() did not apply size_mask after
982          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
983          order to avoid problems with the _NonVolatileReader functions.
984        - bugfix: Stream.h: added a missing divide by BytesPerSample in
985          GetWriteSpace(). Since this function is currently only used in
986          the stream's qsort() compare function, it didn't trigger any
987          bugs.
988        - Resampler.h, Synthesizer.h: cubic interpolation now works in
989          24bit mode too. Faster method to read 24bit words on little
990          endian machines (x86): replaced 3 byte reads + shifts with a 1
991          unaligned 32bit read and shift
992        - experimental support for MS Windows (MIDI input via MME, AUDIO
993          output via ASIO)
994        - made handling of SIGINT signal (Ctrl-C) a bit more robust
995        - support for monitoring the total number of active disk streams
996          (new LSCP commands: GET TOTAL_STREAM_COUNT,
997          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
998    
999      * AUDIO driver:
1000        - added Windows ASIO low latency audio driver
1001    
1002      * MIDI driver:
1003        - added MME Windows MIDI driver
1004    
1005      * LSCP server:
1006        - added support for Windows style path / filenames, however with
1007          forward slash path separators instead of backslash
1008          (i.e. "C:/foo/bar.gig")
1009        - allow naughty liblscp to send non-string device parameters within
1010          apostrophes as well
1011        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1012          "LIST FILE INSTRUMENTS <file>" and
1013          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1014          about an arbitrary instrument file on the system where the sampler is
1015          running on
1016    
1017    Version 0.5.0 (15 October 2007)
1018    
1019      * packaging changes:
1020        - config.h is not going to be installed along with liblinuxsampler's
1021          API header files anymore
1022        - only the API relevant header (and source) files will be exported to
1023          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1024        - added completely new XCode project files for Mac OSX which is now
1025          capable to execute our autoconf environment, thus no need anymore
1026          to maintain the compile time configuration file (osx/version.h) for
1027          OSX manually (patch by Toshi Nagata)
1028        - fixed buggy boolean --enable-foo / --disable-foo configure script
1029          parameters
1030        - global.h now only covers global definitions that are needed for the
1031          C++ API header files, all implementation internal global definitions
1032          are now in global_private.h
1033        - atomic.h is not exposed to the C++ API anymore
1034        - no need to include config.h anymore for using LS's API header files
1035        - fixed warnings in API doc generation
1036    
1037      * general changes:
1038        - replaced the old, confusing MIDI program change mechanism by a
1039          flexible MIDI instrument mapper which allows to map arbitrary
1040          (MIDI bank, MIDI program) pairs with arbitrary
1041          (engine type, instrument file, file index) triplets which will be
1042          loaded on the respective channel when such MIDI program change
1043          messages arrive, beside that, each entry allows to define a life-time
1044          strategy for the instrument, so the user can define whether the
1045          instrument should i.e. be permanently loaded (to be able to switch
1046          quickly among sounds) or i.e. loaded just on demand when the
1047          respective program change arrives (to safe RAM space), as well as a
1048          global volume factor for each entry, so the user can adjust the volume
1049          dynamic of his mapped instrument collection without having to modify
1050          the instrument files, also one can manage arbitrary amount of such
1051          MIDI instrument maps and assign each sampler channel individually
1052          a certain map, so that i.e. separation of normal instruments and
1053          drumkits is possible
1054        - new notification events for tracking changes to audio/MIDI devices,
1055          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1056        - sampler was limited to load max. 200 instruments in the background
1057          due to a constant size RingBuffer FIFO which is now replaced by a
1058          dynamic (unlimited) size std::list FIFO
1059        - added FX sends, these allow to route audio signals to arbitrary audio
1060          output channels for being processed by external effect processors
1061          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1062          controllers
1063        - global (sampler wide) volume can now be controlled at runtime
1064        - Implemented new, improved notification system
1065        - fixed compilation errors regarding OSX
1066          (patch by Toshi Nagata)
1067        - implemented instruments database
1068        - added support for escape sequences to the instruments database
1069        - added highly experimental support for on-the-fly instrument editing
1070          within the sampler's process (by using instrument editor plugins),
1071          you'll notice the new "Registered instrument editors:" message on
1072          startup, added a new LSCP command:
1073          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1074          to spawn a matching instrument editor for the instrument on the
1075          given sampler channel, the plugin path can be overridden at compile
1076          time with ./configure --enable-plugin-dir=/some/dir
1077        - added experimental code for synchronizing instrument editors hosted
1078          in the sampler's process to safely edit instruments while playing
1079          without a crash (hopefully) by either suspending single regions
1080          wherever possible or if unavoidable whole engine(s)
1081        - fixed several issues in fundamental "Thread" class: set scheduling
1082          policy and priority on thread level, set a minimum stack size for
1083          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1084          threads simply inherited properties of starting thread instead of
1085          setting their own policy and priority
1086        - minor fix in our automatic stack trace mechanism on crashes, the
1087          main process did not wait for the stack trace process to finish
1088          its output
1089        - fixed some minor memory leaks
1090        - reenabled assembly features support, at the moment only for
1091          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1092        - minor assembly fix in x86 features detection (don't use the PIC
1093          register, to avoid relocations in the text segment at runtime)
1094        - POSIX callback functions of Thread.h are hidden
1095    
1096      * MIDI driver:
1097        - dispatch bank select (MSB and LSB) messages
1098    
1099      * audio driver:
1100        - the ALSA audio output driver parameters now reflect the correct
1101          parameter value ranges for the respective selected sound card
1102          (patch by Till Wimmer, a bit fixed and extended)
1103    
1104      * Gigasampler format engine:
1105        - if a filter is used and EG2 finishes before EG1, let the voice
1106          die when EG2 has finished (this fixes a problem with clicks and
1107          voice starvation for some gigs)
1108        - playback is no longer disabled during instrument loading
1109        - all notes playing on a channel that changes its instrument keep
1110          playing with the old instrument until they get a note off
1111          command
1112        - EG fix: a release value of zero could cause noises or crash
1113        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1114        - EG fine tuning: when attack is zero the EG starts at a level
1115          above max sustain level, which means that there is a decay phase
1116          even if sustain is 100%
1117        - more EG fixes: the level could sometimes go below zero and cause
1118          noises or crashes
1119        - minor fix of EGDecay (patch by Toshi Nagata)
1120        - fixed compiler error when --enable-override-filter-type was
1121          supplied to the configure script (fixes #46)
1122        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1123          instead of a fix value
1124        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1125          127 (solo mode) only kill voices if the respective mode really
1126          changed
1127    
1128      * LSCP server:
1129        - fixed compile time error for old Bison versions
1130          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1131        - parser now supports extended ASCII character set
1132          (up to ASCII code 255, i.e. includes now umlauts and accents)
1133        - filename arguments in LSCP commands now allow to use escape
1134          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1135          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1136          code value like \xf2) (fixes bug #24)
1137        - the following LSCP commands now also support escape sequences for at
1138          least one of their text-based parameters (i.e. name, description):
1139          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1140          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1141          "SET DB_INSTRUMENT_DIRECTORY NAME",
1142          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1143          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1144          "FIND DB_INSTRUMENT_DIRECTORIES"
1145        - returns verbose syntax errors (line and column where syntax error
1146          occured, the unexpected character and the actually expected, possible
1147          character(s), the latter only if less than 5 possibilities)
1148        - made sure that LSCP syntax is not affected by gigedit locale
1149          settings
1150        - bugfix regarding strings parameter lists: all comma separated lists
1151          of strings were treated as being one string containing commas
1152          (fixes #57)
1153    
1154      * Bug fixes:
1155        - fixed crash occurring on certain LSCP scripts (Bug 39)
1156        - another thread safety fix for lscp "load engine" and "set
1157          channel audio output device"
1158        - fixed a crash which occurs when reassigning the same engine
1159          on a sampler channel with connected MIDI device
1160        - fixed a crash which occurs when changing the number of ports of a MIDI
1161          device connected to a sampler channel to number less then or equal
1162          to the index of the port to which the sampler channel is connected.
1163        - The previous bindings were not been disconnected when altering
1164          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1165          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1166        - The active stream/voice count statistic was incorrect.
1167        - notification events were not been sent for some sampler
1168          channel changes
1169        - added default min and max values to restrict the number of allowed
1170          audio output channels and MIDI input ports
1171        - the connection to the PCM interface is now closed when destroying
1172          an audio output device
1173        - files with slash in their path or filename could not be loaded
1174    
1175      * test cases:
1176        - updated and fixed (haven't been touched in a while)
1177    
1178    Version 0.4.0 (24 November 2006)
1179    
1180      * packaging changes:
1181        - changed deprecated copyright attribute to license; added ldconfig
1182          to post-(un)install steps; added devel package for liblinuxsampler;
1183          to linuxsampler.spec (RPM)

1217      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
1218        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1219          which can be overridden with --enable-global-attenuation
1220        - EG fixes: made the length of "attack hold" stage more
1221          accurate. Release stage can now start before attack stage
1222          ends. Cancel release didn't work when sustain was zero. Attack
1223          time now has a minimal value to prevent clicks.
1224        - fixed pitch changes larger than one octave
1225        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1226        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1227          all modes can be altered via standard GM messages, that is CC5 for
1228          altering portamento time, CC65 for enabling / disabling portamento
1229          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1230        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1231          parameter) and crossfade
1232        - added support for the "attenuation controller threshold" gig
1233          parameter
1234        - added smoothing of volume changes caused by control change
1235          messages
1236        - sample loop parameters are now taken from the DimensionRegion
1237          instead of the wave chunk
1238        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1239          not equal to a power of two
1240        - reimplementation of the filter algorithm. The new filter is more
1241          accurate and supports all gig filter types, including bandreject
1242          and lowpass turbo.
1243        - real support for 24 bit samples - samples are not truncated to
1244          16 bits anymore
1245        - support for aftertouch (channel pressure, not polyphonic
1246          aftertouch)
1247        - LFO1 behaviour fixed (dampening from max volume instead of
1248          amplifying from 0)
