# 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    
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
9        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10          allowing to sort data efficiently in real-time safe manner.
11        - RTList class: added methods for moving/inserting elements to arbitrary
12          position within a list.
13        - RTList class: added method fromPtr() for creating an Iterator object from
14          a raw element pointer.
15        - Attempt to partly fix resetting engine channels vs. resetting engine, an
16          overall cleanup of the Reset*(), ConnectAudioDevice(),
17          DisconnectAudioDevice() API methods would still be desirable though,
18          because the current situation is still inconsistent and error prone.
19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27        - All engines: Increased ramp speed of volume smoother and pan smoother
28          (while slow rate of crossfade smoother is preserved) to allow quick
29          volume and pan changes by instrument scripts for instance.
30        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
31          properly and thus were ignored for certain uses.
32        - Added new C++ API method
33          VirtualMidiDevice::SendChannelPressureToSampler().
34        - windows, 32-bit: fixed potential crashes by making sure the stack in
35          sub threads is 16-byte aligned
36        - fixed numerous compiler warnings
37    
38      * packaging changes:
39        - removed unnecessary dependency to libuuid
40          (originated by libgig's usage of it)
41        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
42          auto detect whether it (sh/c)ould output its messages in color.
43    
44      * Real-time instrument scripts:
45        - Implemented scheduler for delayed MIDI events and for suspended scripts.
46        - Built-in script function "wait()": implemented support for function's
47          "duration-us" argument, thus scripts using this function are now
48          correctly resumed after the requested amount of microseconds.
49        - Built-in script function "play_note()": implemented support for
50          function's "duration-us" argument, thus notes triggered with this
51          argument are now correctly released after the requested amount of
52          microseconds.
53        - Fix: script events were not cleared when engine channel was reset,
54          potentially causing undefined behavior.
55        - Fixed crash which happened when trying to reference an undeclared
56          variable.
57        - Built-in script function "play_note()": Added support for passing
58          special value -1 for "duration-us" argument, which will cause the
59          triggered note to be released once the original note was released.
60        - Instrument script classes now exported with the liblinuxsampler C++ API.
61        - Added new API method ScriptVM::syntaxHighlighting() which provides
62          a convenient syntax highlighting backend for external instrument
63          script editor applications.
64        - Added new C++ API class "ScriptVMFactory".
65        - Extended parser issues to provide not only first line and first
66          column, but also last line and last column of issue (thus marking
67          the precise span of the issue within the source code).
68        - Reload script automatically after being modified by an instrument
69          editor.
70        - NKSP language grammar correction: allow empty event handler bodies
71          like "on note end on".
72        - Implemented built-in script function "change_vol()".
73        - Implemented built-in script function "change_tune()".
74        - Implemented built-in script function "change_pan()".
75        - Implemented built-in script function "change_cutoff()".
76        - Implemented built-in script function "change_reso()".
77        - Implemented built-in script function "event_status()".
78        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
79          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
80          "event_status()" function.
81        - NKSP language: Added support for bitwise operators ".or.", ".and."
82          and ".not.".
83        - NKSP language scanner: Fixed IDs matching to require at least one
84          character (i.e. when matching function names or variable names).
85        - NKSP language scanner: disabled unusued rules.
86        - Fixed behavior of play_note() and note_off() functions which must
87          be distinguished engine internally from "real" MIDI note on/off
88          events in order to avoid misbehaviors like hanging notes.
89        - Implemented built-in script variable "$KSP_TIMER".
90        - Implemented built-in script variable "$NKSP_REAL_TIMER".
91        - Implemented built-in script variable "$NKSP_PERF_TIMER".
92        - Implemented built-in script variable "$ENGINE_UPTIME".
93        - Implemented built-in script function "inc()".
94        - Implemented built-in script function "dec()".
95        - NKSP language fix: division expressions were evaluated too often.
96        - NKSP language fix: string concatenation operator was right
97          associative instead of left (to right).
98        - NKSP language correction: allow empty statements in entire language
99          (i.e. "if end if").
100        - Implemented built-in script function "stop_wait()".
101        - Implemented built-in script variable "$NI_CALLBACK_ID".
102        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
103        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
104        - Added support for read-only built-in variables (respectively
105          handled by the script parser).
106        - Added built-in script constant "$NI_CB_TYPE_INIT".
107        - Added built-in script constant "$NI_CB_TYPE_NOTE".
108        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
109        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
110        - NKSP Language: Added support for user defined script functions.
111        - Implemented built-in script function "change_attack()".
112        - Implemented built-in script function "change_decay()".
113        - Implemented built-in script function "change_release()".
114        - Fixed all change_*() built-in script functions to apply their
115          synthesis parameter changes immediately in case the respective note
116          was triggered at the same time, instead of scheduling the parameter
117          change, especially because it would cause some parameter types's
118          changes either to be ramped (i.e. change_vol()) or other types even
119          to have not effect at all (i.e. change_attack()).
120        - Implemented built-in script function "sh_left()".
121        - Implemented built-in script function "sh_right()".
122        - Implemented built-in script function "min()".
123        - Implemented built-in script function "max()".
124        - NKSP Fix: "init" event handler was not always executed when a script
125          was loaded.
126        - NKSP built-in wait() script function: abort script execution if
127          a negative or zero wait time was passed as argument (since this is
128          a common indication of a bug either of the script or even of the
129          engine, which could lead to RT instability or even worse).
130        - ScriptVM: Implemented automatic suspension of RT safety
131          threatening scripts.
132        - Provide more user friendly error messages on syntax errors.
133        - Fixed NKSP parser warning "Not a statement" when assigning an
134          initializer list to an array variable.
135    
136      * Instruments DB:
137        - Fixed memory access bug of general DB access code which lead to
138          undefined behavior.
139    
140    Version 2.0.0 (15 July 2015)
141    
142      * packaging changes:

144        - Mac OS X: support the new dir for Core Audio SDK
145        - Mac OS X: fixed building outside source directory
146        - made sure all source files for hostplugins are included when
147          doing "make dist"
148        - removed empty directories left from the cvs to svn migration
149        - fixed compilation with gcc 4.6.1
150        - another "make dist" fix, for the LV2 plugin
151        - made --enable-pthread-testcancel default on Mac OS X
152        - minor Makefile fix for building lscpparser when build and source
153          directories are separate
154        - Mac OS X: made it possible to specify plugin installation dir to
155          configure
156        - Mac OS X: Makefile fix for the install-strip target
157        - fixed compilation with gcc 4.7
158        - fixed configure script error with old autoconf versions
159        - lsatomic.h: use gcc provided atomic functions if building with
160          gcc 4.7 and C++11
161        - modernized configure script
162        - fixed linkage error when building with
163          LDFLAGS="-Wl,--no-undefined" (#190)
164        - fixed compilation with Clang 3.2
165        - removed usage of deprecated Automake variable INCLUDES

173        - fixed build error on newer MinGW
174        - support building with older jack versions
175        - support building with spaces in vst sdk path
176        - enabled automake 'subdir-objects' option and moved external
177          source references (vst, au, asio) from makefiles to cpp files,
178          in order to get rid of warnings from automake 1.14
179    
180      * general changes:
181        - Refactoring: moved the independent code from
182          the Gigasampler format engine to base classes
183        - command line option '--profile' is currently disabled, since the
184          respective profiling code is currently broken
185        - Introduced support for optional environment variable
186          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
187          where the sampler shall look for instrument editor plugins
188          (patch by Luis Garrido, slightly modified).
189        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
190        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
191        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
192          note (in this implementation of the sampler its simply hard routed to
193          the 1st effect send of the sampler channel, no matter what the actual
194          effect type is)
195        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
196          note (in this implementation of the sampler its simply hard routed to
197          the 2nd effect send of the sampler channel, no matter what the actual
198          effect type is)
199        - implemented support for internal LADSPA effects
200        - raised limit of program change queue from 100 to 512
201          (as suggested by Alex Stone)
202        - implemented sine LFO, pulse LFO and saw LFO
203        - experimental support for per voice equalization
204        - added command line option --exec-after-init
205        - Introduced new C++ API method:
206          EngineChannel::InstrumentFileName(int index)
207          allowing to retrieve the whole list of files used for the loaded
208          instrument on an engine channel (a.k.a. part). Some GigaStudio
209          instruments for example are splitted over several files like
210          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
211        - Added new C++ API method Sampler::GetGlobalMaxVoices().
212        - Added new C++ API method Sampler::GetGlobalMaxStreams().
213        - Added new C++ API method Sampler::SetGlobalMaxVoices().
214        - Added new C++ API method Sampler::SetGlobalMaxStreams().
215        - Various "const" and "restrict" optimizations.
216        - all engines: add pan CC value to instrument pan parameter before
217          applying panning, instead of using two separate pan functions in
218          series (#182)
219        - added a lock guard class for exception safe mutex handling and
220          used it everywhere appropriate
221        - Immediately apply scale tuning changes to active voices.
222        - Exposed scale tuning to C++ API (along to the already existing standard
223          SysEx way).
224        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
225          and broken for ppc64. (Seq_cst loads and stores are actually not
226          used in LS, so the bug wasn't noticable.)
227        - lsatomic.h: added ARMv7 support
228        - Added support for multiple MIDI input ports per sampler channel (and
229          added various new C++ methods for this new feature / design change, old
230          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
231          as deprecated but are still there and should provide full behavior
232          backward compatibility).
233        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
234          unsafe and caused compilation error with clang 2.x).
235        - Bugfix: only process the latest MIDI program change event.
236        - Introducing the LSCP shell, which provides convenient control of the
237          sampler from the command line by providing LSCP aware features.
238        - VirtualMidiDevice: Added support for program change.
239        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
240        - VirtualMidiDevice: Added support for pitch bend.
241        - Aftertouch: extended API to explicitly handle channel pressure and
242          polyphonic key pressure events (so far polyphonic pressure was not
243          supported at all, and channel pressure was rerouted as CC128 but not
244          used so far).
245        - Added initial support for real-time instrument scripts. The script VM
246          code is shared by all sampler engine implemementations, however only the
247          gig file format currently provides support for storing instrument scripts
248          (as LinuxSampler extension to the original GigaStudio 4 format).
249    
250      * Gigasampler format engine:
251        - implemented the "round robin keyboard" dimension
252        - fixed round robin and random dimensions for cases when number of
253          dimension zones is not a power of two
254        - made round robin use a counter for each region instead of each
255          key
256        - bugfix: pitch LFO controller "internal+aftertouch" was broken
257        - bugfix: filter keyboard tracking was broken
258        - filter performance fix (an unnecessary copy was made of the
259          filter parameters in each sub fragment)
260        - handle special case when pan parameter in gig file has max or
261          min value
262        - Exclusive Groups: don't ever stop voices of the same note,
263          doesn't sound naturally with a drumkit
264        - fixed EG1 modulation when attack or release is zero
265        - Fixed support for 'aftertouch' attenuation controller.
266        - Fixed crash that happened with velocity split sounds under certain
267          conditions (see also previous commit on libgig).
268        - fixed behaviour of filter LFO
269    
270      * SFZ format engine:
271        - Initial implementation (not usable yet)
272        - added support for v2 multiple stage envelope generators
273        - added a fine-tuned v1 envelope generator instead of using the
274          one from the gig engine
275        - fixed memory leak and memory handling errors
276        - added support for trigger=first, trigger=legato and sw_previous
277        - allow non-numerical key values ("C#4" for example)
278        - "key" opcode now sets pitch_keycenter too
279        - fixed error when unloading instrument with same sample used by
280          multiple regions
281        - added some opcode aliases, like loopmode for loop_mode, to be
282          more compatible
283        - added support for trigger=release and rt_decay
284        - added support for off_mode=normal
285        - added support for random, seq_position, seq_length and volume
286        - added v1 LFO opcodes to parser (no support in engine yet)
287        - added support for amp_veltrack and amp_velcurve_N
288        - fine-tuned the default velocity curve
289        - added support for transpose
290        - fixed crash when using sw_down/up
291        - improved logic for sw_lokey/hikey/up/down/last
292        - added more v1 aliases to parser
293        - reduced memory usage for sfz data
294        - RT-safeness: avoid malloc in audio thread
295        - fixed a bug that could cause voice stealing to fail
296        - optimized sample lookup
297        - improved support for exclusive groups (group, off_by and
298          off_mode)
299        - added support for controller triggered regions (on_locc/on_hicc)
300        - added support for loop_mode=one_shot
301        - fixed playback of 16 bit wav files on big endian CPUs
302        - added support for Ogg Vorbis sample files
303        - use loop markers from sample file if loop_start and loop_end are
304          not set in sfz file
305        - implemeted filters. Filter types: lowpass, bandpass, bandreject
306          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
307          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
308          cutoff_cc, cutoff_chanaft.
309        - bugfix: zero ampeg_sustain didn't work
310        - added support for velocity effect on amplifier envelope time
311          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
312          ampeg_vel2release)
313        - added support for EG hold (ampeg_hold)

449          incorrectly set to two. This caused silence in Cubase 5.
450        - save engine type (gig, sfz or sf2) in plugin state
451        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
452          64 bit Windows

491          there is no reason for this limit
492        - MME: fixed memory handling bug found with cppcheck
493        - MME: removed compiler warning
494        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
495          which allows to retrieve the list of CoreMIDI clients / ports and to connect
496          to them a la JACK, via the usual sampler APIs
497        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled

507        - MME bugfix: driver wasn't closed properly
508        - CoreMIDI: automatically connect to all input sources by default (driver
509          parameter "AUTO_BIND").
510        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
511        - CoreMIDI: fixed minor memory leak
512    
513      * audio driver:
514        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
515        - JACK audio: react on sample rate changes.

518          RT context.
519        - ASIO driver: removed compiler warnings
520        - CoreAudio: fixed minor error handling bug
521        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

574        - Added support for built-in LSCP reference documentation, which will
575          automatically show the relevant LSCP reference section on screen as soon
576          as one specific LSCP command was detected while typing on the command

638        - bugfix: calling SET VOICES (which Fantasia does on start and
639          refresh) could cause instruments to be unloaded
640        - Mac OS X: fixed name collision of enum in EffectControl and
641          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
642        - Mac OS X: fixed hanging threads

646          after MIDI/audio device creation failure
647        - When creating MIDI instrument map entries with "PERSISTENT" type, the
648          instruments were uselessly precached with zero samples, however it still
649          took the full preloading time and on 1st program change the respective
650          instrument was completely reloaded again.
651        - fixed handling of rapid bank select and program change messages
652          sent to the same sampler channel (patch from the Open Octave

666          introduced in previous fix)
667        - fixed crash when a channel received a program change while
668          playing a note in a key group
669        - fixed erroneous error message piping in VoiceBase.h
670          (labelled "Disk stream not available in time")
671        - Update effects on sample rate & period size changes (to avoid
672          crashes and noise on such transitions).
673        - ignore missing LADSPA paths without ignoring valid LADSPA paths
674          (fixes #208)
675        - Fixed bug in LSCP grammar definition which caused a statement like
676          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
677          practically irrelevant, however it caused problems with the new LSCP
678          shell's auto completion feature).
679        - Fixed MIDI program change messages being ignored if quickly executed
680          after each other (fixes #231).
681    
682    Version 1.0.0 (31 July 2009)
683    
684      * packaging changes:
685        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

687          "./configure --disable-jack-driver" was used
688          (patch by Alexis Ballier)

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

1105        - The previous bindings were not been disconnected when altering
1106          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1107          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
