# 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    
167      * Instruments DB:
168        - Fixed memory access bug of general DB access code which lead to
169          undefined behavior.
170        - Cleanup of instruments DB file creation and opening code.
171        - The instrument DB path of linuxsampler's --create-instruments-db argument
172          is now optional, if it is missing, then a default location is used.
173        - Added support for scanning SFZ (.sfz) files.
174        - Added support for scanning Sound Font (.sf2) files.
175        - Fixed undefined DB transaction behavior.

181        - Mac OS X: support the new dir for Core Audio SDK
182        - Mac OS X: fixed building outside source directory
183        - made sure all source files for hostplugins are included when
184          doing "make dist"
185        - removed empty directories left from the cvs to svn migration
186        - fixed compilation with gcc 4.6.1
187        - another "make dist" fix, for the LV2 plugin
188        - made --enable-pthread-testcancel default on Mac OS X
189        - minor Makefile fix for building lscpparser when build and source
190          directories are separate
191        - Mac OS X: made it possible to specify plugin installation dir to
192          configure
193        - Mac OS X: Makefile fix for the install-strip target
194        - fixed compilation with gcc 4.7
195        - fixed configure script error with old autoconf versions

197          gcc 4.7 and C++11
198        - modernized configure script
199        - fixed linkage error when building with
200          LDFLAGS="-Wl,--no-undefined" (#190)

210        - fixed build error on newer MinGW
211        - support building with older jack versions
212        - support building with spaces in vst sdk path
213        - enabled automake 'subdir-objects' option and moved external
214          source references (vst, au, asio) from makefiles to cpp files,
215          in order to get rid of warnings from automake 1.14
216    
217      * general changes:
218        - Refactoring: moved the independent code from
219          the Gigasampler format engine to base classes
220        - command line option '--profile' is currently disabled, since the
221          respective profiling code is currently broken
222        - Introduced support for optional environment variable
223          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
224          where the sampler shall look for instrument editor plugins
225          (patch by Luis Garrido, slightly modified).
226        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
227        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
228        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
229          note (in this implementation of the sampler its simply hard routed to
230          the 1st effect send of the sampler channel, no matter what the actual
231          effect type is)
232        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
233          note (in this implementation of the sampler its simply hard routed to
234          the 2nd effect send of the sampler channel, no matter what the actual
235          effect type is)
236        - implemented support for internal LADSPA effects
237        - raised limit of program change queue from 100 to 512
238          (as suggested by Alex Stone)
239        - implemented sine LFO, pulse LFO and saw LFO
240        - experimental support for per voice equalization
241        - added command line option --exec-after-init
242        - Introduced new C++ API method:
243          EngineChannel::InstrumentFileName(int index)
244          allowing to retrieve the whole list of files used for the loaded
245          instrument on an engine channel (a.k.a. part). Some GigaStudio
246          instruments for example are splitted over several files like
247          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
248        - Added new C++ API method Sampler::GetGlobalMaxVoices().
249        - Added new C++ API method Sampler::GetGlobalMaxStreams().
250        - Added new C++ API method Sampler::SetGlobalMaxVoices().
251        - Added new C++ API method Sampler::SetGlobalMaxStreams().
252        - Various "const" and "restrict" optimizations.
253        - all engines: add pan CC value to instrument pan parameter before
254          applying panning, instead of using two separate pan functions in
255          series (#182)
256        - added a lock guard class for exception safe mutex handling and
257          used it everywhere appropriate
258        - Immediately apply scale tuning changes to active voices.
259        - Exposed scale tuning to C++ API (along to the already existing standard
260          SysEx way).
261        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
262          and broken for ppc64. (Seq_cst loads and stores are actually not
263          used in LS, so the bug wasn't noticable.)
264        - lsatomic.h: added ARMv7 support
265        - Added support for multiple MIDI input ports per sampler channel (and
266          added various new C++ methods for this new feature / design change, old
267          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
268          as deprecated but are still there and should provide full behavior
269          backward compatibility).
270        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
271          unsafe and caused compilation error with clang 2.x).
272        - Bugfix: only process the latest MIDI program change event.
273        - Introducing the LSCP shell, which provides convenient control of the
274          sampler from the command line by providing LSCP aware features.
275        - VirtualMidiDevice: Added support for program change.
276        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
277        - VirtualMidiDevice: Added support for pitch bend.
278        - Aftertouch: extended API to explicitly handle channel pressure and
279          polyphonic key pressure events (so far polyphonic pressure was not
280          supported at all, and channel pressure was rerouted as CC128 but not
281          used so far).
282        - Added initial support for real-time instrument scripts. The script VM
283          code is shared by all sampler engine implemementations, however only the
284          gig file format currently provides support for storing instrument scripts
285          (as LinuxSampler extension to the original GigaStudio 4 format).
286    
287      * Gigasampler format engine:
288        - implemented the "round robin keyboard" dimension
289        - fixed round robin and random dimensions for cases when number of
290          dimension zones is not a power of two
291        - made round robin use a counter for each region instead of each
292          key
293        - bugfix: pitch LFO controller "internal+aftertouch" was broken
294        - bugfix: filter keyboard tracking was broken
295        - filter performance fix (an unnecessary copy was made of the
296          filter parameters in each sub fragment)
297        - handle special case when pan parameter in gig file has max or
298          min value
299        - Exclusive Groups: don't ever stop voices of the same note,
300          doesn't sound naturally with a drumkit
301        - fixed EG1 modulation when attack or release is zero
302        - Fixed support for 'aftertouch' attenuation controller.
303        - Fixed crash that happened with velocity split sounds under certain
304          conditions (see also previous commit on libgig).
305        - fixed behaviour of filter LFO
306    
307      * SFZ format engine:
308        - Initial implementation (not usable yet)
309        - added support for v2 multiple stage envelope generators
310        - added a fine-tuned v1 envelope generator instead of using the
311          one from the gig engine
312        - fixed memory leak and memory handling errors
313        - added support for trigger=first, trigger=legato and sw_previous
314        - allow non-numerical key values ("C#4" for example)
315        - "key" opcode now sets pitch_keycenter too
316        - fixed error when unloading instrument with same sample used by
317          multiple regions
318        - added some opcode aliases, like loopmode for loop_mode, to be
319          more compatible
320        - added support for trigger=release and rt_decay
321        - added support for off_mode=normal
322        - added support for random, seq_position, seq_length and volume
323        - added v1 LFO opcodes to parser (no support in engine yet)
324        - added support for amp_veltrack and amp_velcurve_N
325        - fine-tuned the default velocity curve
326        - added support for transpose
327        - fixed crash when using sw_down/up
328        - improved logic for sw_lokey/hikey/up/down/last
329        - added more v1 aliases to parser
330        - reduced memory usage for sfz data
331        - RT-safeness: avoid malloc in audio thread
332        - fixed a bug that could cause voice stealing to fail
333        - optimized sample lookup
334        - improved support for exclusive groups (group, off_by and
335          off_mode)
336        - added support for controller triggered regions (on_locc/on_hicc)
337        - added support for loop_mode=one_shot
338        - fixed playback of 16 bit wav files on big endian CPUs
339        - added support for Ogg Vorbis sample files
340        - use loop markers from sample file if loop_start and loop_end are
341          not set in sfz file
342        - implemeted filters. Filter types: lowpass, bandpass, bandreject
343          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
344          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
345          cutoff_cc, cutoff_chanaft.
346        - bugfix: zero ampeg_sustain didn't work
347        - added support for velocity effect on amplifier envelope time
348          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
349          ampeg_vel2release)
350        - added support for EG hold (ampeg_hold)
351        - added support for sample offset (offset)
352        - use the newly introduced signal units model

486          incorrectly set to two. This caused silence in Cubase 5.
487        - save engine type (gig, sfz or sf2) in plugin state
488        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
489          64 bit Windows

544        - MME bugfix: driver wasn't closed properly
545        - CoreMIDI: automatically connect to all input sources by default (driver
546          parameter "AUTO_BIND").

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

1046        - implemented instruments database
1047        - added support for escape sequences to the instruments database
1048        - added highly experimental support for on-the-fly instrument editing
1049          within the sampler's process (by using instrument editor plugins),
1050          you'll notice the new "Registered instrument editors:" message on
1051          startup, added a new LSCP command:
1052          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1053          to spawn a matching instrument editor for the instrument on the
1054          given sampler channel, the plugin path can be overridden at compile
1055          time with ./configure --enable-plugin-dir=/some/dir
1056        - added experimental code for synchronizing instrument editors hosted
1057          in the sampler's process to safely edit instruments while playing
1058          without a crash (hopefully) by either suspending single regions
1059          wherever possible or if unavoidable whole engine(s)
1060        - fixed several issues in fundamental "Thread" class: set scheduling
1061          policy and priority on thread level, set a minimum stack size for
1062          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1063          threads simply inherited properties of starting thread instead of
1064          setting their own policy and priority
1065        - minor fix in our automatic stack trace mechanism on crashes, the
1066          main process did not wait for the stack trace process to finish
1067          its output
1068        - fixed some minor memory leaks
1069        - reenabled assembly features support, at the moment only for
1070          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1071        - minor assembly fix in x86 features detection (don't use the PIC
1072          register, to avoid relocations in the text segment at runtime)
1073        - POSIX callback functions of Thread.h are hidden

1091      - EG fix: a release value of zero could cause noises or crash      - EG fix: a release value of zero could cause noises or crash
1092      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1093        - EG fine tuning: when attack is zero the EG starts at a level
1094          above max sustain level, which means that there is a decay phase
1095          even if sustain is 100%
1096        - more EG fixes: the level could sometimes go below zero and cause
1097          noises or crashes
1098        - minor fix of EGDecay (patch by Toshi Nagata)
1099        - fixed compiler error when --enable-override-filter-type was
1100          supplied to the configure script (fixes #46)
1101        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1102          instead of a fix value
1103        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1104          127 (solo mode) only kill voices if the respective mode really
1105          changed

1107      * LSCP server:
1108        - fixed compile time error for old Bison versions
1109          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1110        - parser now supports extended ASCII character set
1111          (up to ASCII code 255, i.e. includes now umlauts and accents)
1112        - filename arguments in LSCP commands now allow to use escape
1113          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1114          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1115          code value like \xf2) (fixes bug #24)
1116        - the following LSCP commands now also support escape sequences for at
1117          least one of their text-based parameters (i.e. name, description):
1118          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1119          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1120          "SET DB_INSTRUMENT_DIRECTORY NAME",
1121          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1122          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1123          "FIND DB_INSTRUMENT_DIRECTORIES"
1124        - returns verbose syntax errors (line and column where syntax error
1125          occured, the unexpected character and the actually expected, possible
1126          character(s), the latter only if less than 5 possibilities)
1127        - made sure that LSCP syntax is not affected by gigedit locale
1128          settings
1129        - bugfix regarding strings parameter lists: all comma separated lists
1130          of strings were treated as being one string containing commas
1131          (fixes #57)

1134      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
1135      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
1136        channel audio output device"        channel audio output device"
1137        - fixed a crash which occurs when reassigning the same engine
1138          on a sampler channel with connected MIDI device
1139        - fixed a crash which occurs when changing the number of ports of a MIDI
1140          device connected to a sampler channel to number less then or equal
1141          to the index of the port to which the sampler channel is connected.
1142        - The previous bindings were not been disconnected when altering
1143          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1144          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1145        - The active stream/voice count statistic was incorrect.
1146        - notification events were not been sent for some sampler
1147          channel changes
1148        - added default min and max values to restrict the number of allowed
1149          audio output channels and MIDI input ports
1150        - the connection to the PCM interface is now closed when destroying
1151          an audio output device
1152        - files with slash in their path or filename could not be loaded
1153    
1154      * test cases:
