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

185        - Mac OS X: support the new dir for Core Audio SDK
186        - Mac OS X: fixed building outside source directory
187        - made sure all source files for hostplugins are included when
188          doing "make dist"
189        - removed empty directories left from the cvs to svn migration
190        - fixed compilation with gcc 4.6.1
191        - another "make dist" fix, for the LV2 plugin
192        - made --enable-pthread-testcancel default on Mac OS X
193        - minor Makefile fix for building lscpparser when build and source
194          directories are separate
195        - Mac OS X: made it possible to specify plugin installation dir to
196          configure
197        - Mac OS X: Makefile fix for the install-strip target
198        - fixed compilation with gcc 4.7
199        - fixed configure script error with old autoconf versions
200        - lsatomic.h: use gcc provided atomic functions if building with
201          gcc 4.7 and C++11
202        - modernized configure script
203        - fixed linkage error when building with
204          LDFLAGS="-Wl,--no-undefined" (#190)

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

490          incorrectly set to two. This caused silence in Cubase 5.
491        - save engine type (gig, sfz or sf2) in plugin state
492        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
493          64 bit Windows

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

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