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

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

699        - Implemented built-in script function "by_marks()".
700        - Added built-in script int const variables $MARK_1 to $MARK_28.
701        - Built-in script functions "ignore_event()", "note_off()" and
702          "gig_set_dim_zone()" now also accept an array of event IDs as argument
703          (i.e. return value of new script function "by_marks()").
704        - Pass/preserve polyphonic variable data from respective "note" event
705          handler to "release" event handler.
706        - Fixed crash when using built-in script function "by_marks()".
707    
708      * Bug fixes:
709        - Fixed crash which may occur when MIDI key + transpose is out of range
710        - minor valgrind fixes
711        - fixed crash which occurred when changing an already deployed sampler
712          channel to a different engine type
713        - fixed crash when deleting a sampler channel or changing engine
714          type while an instrument load was in progress
715        - bugfix: playing a note while changing the instrument could cause
716          a crash, or give "Handing back unknown region" error messages
717        - bugfix: calling SET VOICES (which Fantasia does on start and
718          refresh) could cause instruments to be unloaded
719        - Mac OS X: fixed name collision of enum in EffectControl and
720          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
721        - Mac OS X: fixed hanging threads
722        - Windows: disabled the previous thread fix on non-Mac systems, as
723          it caused hanging threads on Windows
724        - Fixed possible crashes due to corrupted MIDI/audio device list
725          after MIDI/audio device creation failure
726        - When creating MIDI instrument map entries with "PERSISTENT" type, the
727          instruments were uselessly precached with zero samples, however it still
728          took the full preloading time and on 1st program change the respective
729          instrument was completely reloaded again.
730        - fixed handling of rapid bank select and program change messages
731          sent to the same sampler channel (patch from the Open Octave
732          project, slightly adjusted)
733        - fixed crash when trying to create an effect instance with controls
734          which min and/or max values depend on the sample rate
735        - fixed bug #162
736        - bugfix: LADSPA_PATH was not evaluated correctly when containing
737          multiple paths (#165)

743        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
744        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
745          introduced in previous fix)
746        - fixed crash when a channel received a program change while
747          playing a note in a key group
748        - fixed erroneous error message piping in VoiceBase.h
749          (labelled "Disk stream not available in time")
750        - Update effects on sample rate & period size changes (to avoid
751          crashes and noise on such transitions).
752        - ignore missing LADSPA paths without ignoring valid LADSPA paths
753          (fixes #208)
754        - Fixed bug in LSCP grammar definition which caused a statement like
755          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
756          practically irrelevant, however it caused problems with the new LSCP
757          shell's auto completion feature).
758        - Fixed MIDI program change messages being ignored if quickly executed
759          after each other (fixes #231).
760    
761    Version 1.0.0 (31 July 2009)
762    
763      * packaging changes:
764        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
765          causing e.g. the libgig test to fail when
766          "./configure --disable-jack-driver" was used
767          (patch by Alexis Ballier)
768        - fixed compilation with gcc 4.3
769        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

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

1088        - implemented instruments database
1089        - added support for escape sequences to the instruments database
1090        - added highly experimental support for on-the-fly instrument editing
1091          within the sampler's process (by using instrument editor plugins),
1092          you'll notice the new "Registered instrument editors:" message on
1093          startup, added a new LSCP command:
1094          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1095          to spawn a matching instrument editor for the instrument on the
1096          given sampler channel, the plugin path can be overridden at compile
1097          time with ./configure --enable-plugin-dir=/some/dir
1098        - added experimental code for synchronizing instrument editors hosted
1099          in the sampler's process to safely edit instruments while playing
1100          without a crash (hopefully) by either suspending single regions
1101          wherever possible or if unavoidable whole engine(s)
1102        - fixed several issues in fundamental "Thread" class: set scheduling
1103          policy and priority on thread level, set a minimum stack size for
1104          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1105          threads simply inherited properties of starting thread instead of
1106          setting their own policy and priority
1107        - minor fix in our automatic stack trace mechanism on crashes, the
1108          main process did not wait for the stack trace process to finish
1109          its output
1110        - fixed some minor memory leaks
1111        - reenabled assembly features support, at the moment only for
1112          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1113        - minor assembly fix in x86 features detection (don't use the PIC
1114          register, to avoid relocations in the text segment at runtime)
1115        - POSIX callback functions of Thread.h are hidden
1116

1141        - fixed compiler error when --enable-override-filter-type was
1142          supplied to the configure script (fixes #46)
1143        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1144          instead of a fix value
1145        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1146          127 (solo mode) only kill voices if the respective mode really
1147          changed
1148    
1149      * LSCP server:
1150        - fixed compile time error for old Bison versions
1151          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1152        - parser now supports extended ASCII character set
1153          (up to ASCII code 255, i.e. includes now umlauts and accents)
1154        - filename arguments in LSCP commands now allow to use escape
1155          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1156          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1157          code value like \xf2) (fixes bug #24)
1158        - the following LSCP commands now also support escape sequences for at
1159          least one of their text-based parameters (i.e. name, description):
1160          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1161          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1162          "SET DB_INSTRUMENT_DIRECTORY NAME",
1163          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1164          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1165          "FIND DB_INSTRUMENT_DIRECTORIES"
1166        - returns verbose syntax errors (line and column where syntax error
1167          occured, the unexpected character and the actually expected, possible
1168          character(s), the latter only if less than 5 possibilities)
1169        - made sure that LSCP syntax is not affected by gigedit locale
1170          settings
1171        - bugfix regarding strings parameter lists: all comma separated lists
1172          of strings were treated as being one string containing commas
1173          (fixes #57)
1174    
1175    * Bug fixes:    * Bug fixes:
1176      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
1177      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
1178        channel audio output device"        channel audio output device"
1179        - fixed a crash which occurs when reassigning the same engine
1180          on a sampler channel with connected MIDI device
1181        - fixed a crash which occurs when changing the number of ports of a MIDI
1182          device connected to a sampler channel to number less then or equal
1183          to the index of the port to which the sampler channel is connected.
1184        - The previous bindings were not been disconnected when altering
1185          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1186          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1187        - The active stream/voice count statistic was incorrect.
1188        - notification events were not been sent for some sampler
1189          channel changes
1190        - added default min and max values to restrict the number of allowed
1191          audio output channels and MIDI input ports
1192        - the connection to the PCM interface is now closed when destroying
1193          an audio output device
1194        - files with slash in their path or filename could not be loaded
1195    
1196      * test cases:
1197        - updated and fixed (haven't been touched in a while)
