# 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    
28      * packaging changes:
29        - removed unnecessary dependency to libuuid
30          (originated by libgig's usage of it)
31        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32          auto detect whether it (sh/c)ould output its messages in color.
33    
34      * Real-time instrument scripts:
35        - Implemented scheduler for delayed MIDI events and for suspended scripts.
36        - Built-in script function "wait()": implemented support for function's
37          "duration-us" argument, thus scripts using this function are now
38          correctly resumed after the requested amount of microseconds.
39        - Built-in script function "play_note()": implemented support for
40          function's "duration-us" argument, thus notes triggered with this
41          argument are now correctly released after the requested amount of
42          microseconds.
43        - Fix: script events were not cleared when engine channel was reset,
44          potentially causing undefined behavior.
45        - Fixed crash which happened when trying to reference an undeclared
46          variable.
47        - Built-in script function "play_note()": Added support for passing
48          special value -1 for "duration-us" argument, which will cause the
49          triggered note to be released once the original note was released.
50        - Instrument script classes now exported with the liblinuxsampler C++ API.
51        - Added new API method ScriptVM::syntaxHighlighting() which provides
52          a convenient syntax highlighting backend for external instrument
53          script editor applications.
54        - Added new C++ API class "ScriptVMFactory".
55        - Extended parser issues to provide not only first line and first
56          column, but also last line and last column of issue (thus marking
57          the precise span of the issue within the source code).
58        - Reload script automatically after being modified by an instrument
59          editor.
60        - NKSP language grammar correction: allow empty event handler bodies
61          like "on note end on".
62        - Implemented built-in script function "change_vol()".
63        - Implemented built-in script function "change_tune()".
64        - Implemented built-in script function "change_pan()".
65        - Implemented built-in script function "change_cutoff()".
66        - Implemented built-in script function "change_reso()".
67        - Implemented built-in script function "event_status()".
68        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70          "event_status()" function.
71        - NKSP language: Added support for bitwise operators ".or.", ".and."
72          and ".not.".
73        - NKSP language scanner: Fixed IDs matching to require at least one
74          character (i.e. when matching function names or variable names).
75        - NKSP language scanner: disabled unusued rules.
76        - Fixed behavior of play_note() and note_off() functions which must
77          be distinguished engine internally from "real" MIDI note on/off
78          events in order to avoid misbehaviors like hanging notes.
79        - Implemented built-in script variable "$KSP_TIMER".
80        - Implemented built-in script variable "$NKSP_REAL_TIMER".
81        - Implemented built-in script variable "$NKSP_PERF_TIMER".
82        - Implemented built-in script variable "$ENGINE_UPTIME".
83        - Implemented built-in script function "inc()".
84        - Implemented built-in script function "dec()".
85        - NKSP language fix: division expressions were evaluated too often.
86        - NKSP language fix: string concatenation operator was right
87          associative instead of left (to right).
88        - NKSP language correction: allow empty statements in entire language
89          (i.e. "if end if").
90        - Implemented built-in script function "stop_wait()".
91        - Implemented built-in script variable "$NI_CALLBACK_ID".
92        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
93        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
94        - Added support for read-only built-in variables (respectively
95          handled by the script parser).
96        - Added built-in script constant "$NI_CB_TYPE_INIT".
97        - Added built-in script constant "$NI_CB_TYPE_NOTE".
98        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
99        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
100        - NKSP Language: Added support for user defined script functions.
101        - Implemented built-in script function "change_attack()".
102        - Implemented built-in script function "change_decay()".
103        - Implemented built-in script function "change_release()".
104        - Fixed all change_*() built-in script functions to apply their
105          synthesis parameter changes immediately in case the respective note
106          was triggered at the same time, instead of scheduling the parameter
107          change, especially because it would cause some parameter types's
108          changes either to be ramped (i.e. change_vol()) or other types even
109          to have not effect at all (i.e. change_attack()).
110    
111    Version 2.0.0 (15 July 2015)
112    
113      * packaging changes:

119        - removed empty directories left from the cvs to svn migration
120        - fixed compilation with gcc 4.6.1
121        - another "make dist" fix, for the LV2 plugin
122        - made --enable-pthread-testcancel default on Mac OS X
123        - minor Makefile fix for building lscpparser when build and source
124          directories are separate
125        - Mac OS X: made it possible to specify plugin installation dir to
126          configure
127        - Mac OS X: Makefile fix for the install-strip target
128        - fixed compilation with gcc 4.7

144        - fixed build error on newer MinGW
145        - support building with older jack versions
146        - support building with spaces in vst sdk path
147        - enabled automake 'subdir-objects' option and moved external
148          source references (vst, au, asio) from makefiles to cpp files,
149          in order to get rid of warnings from automake 1.14
150    
151      * general changes:
152        - Refactoring: moved the independent code from
153          the Gigasampler format engine to base classes
154        - command line option '--profile' is currently disabled, since the
155          respective profiling code is currently broken
156        - Introduced support for optional environment variable
157          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
158          where the sampler shall look for instrument editor plugins
159          (patch by Luis Garrido, slightly modified).
160        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
161        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
162        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
163          note (in this implementation of the sampler its simply hard routed to
164          the 1st effect send of the sampler channel, no matter what the actual
165          effect type is)
166        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
167          note (in this implementation of the sampler its simply hard routed to
168          the 2nd effect send of the sampler channel, no matter what the actual
169          effect type is)
170        - implemented support for internal LADSPA effects
171        - raised limit of program change queue from 100 to 512
172          (as suggested by Alex Stone)
173        - implemented sine LFO, pulse LFO and saw LFO
174        - experimental support for per voice equalization
175        - added command line option --exec-after-init
176        - Introduced new C++ API method:
177          EngineChannel::InstrumentFileName(int index)
178          allowing to retrieve the whole list of files used for the loaded
179          instrument on an engine channel (a.k.a. part). Some GigaStudio
180          instruments for example are splitted over several files like
181          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
182        - Added new C++ API method Sampler::GetGlobalMaxVoices().
183        - Added new C++ API method Sampler::GetGlobalMaxStreams().
184        - Added new C++ API method Sampler::SetGlobalMaxVoices().
185        - Added new C++ API method Sampler::SetGlobalMaxStreams().
186        - Various "const" and "restrict" optimizations.
187        - all engines: add pan CC value to instrument pan parameter before
188          applying panning, instead of using two separate pan functions in
189          series (#182)
190        - added a lock guard class for exception safe mutex handling and
191          used it everywhere appropriate
192        - Immediately apply scale tuning changes to active voices.
193        - Exposed scale tuning to C++ API (along to the already existing standard
194          SysEx way).
195        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
196          and broken for ppc64. (Seq_cst loads and stores are actually not
197          used in LS, so the bug wasn't noticable.)
198        - lsatomic.h: added ARMv7 support
199        - Added support for multiple MIDI input ports per sampler channel (and
200          added various new C++ methods for this new feature / design change, old
201          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
202          as deprecated but are still there and should provide full behavior
203          backward compatibility).
204        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
205          unsafe and caused compilation error with clang 2.x).
206        - Bugfix: only process the latest MIDI program change event.
207        - Introducing the LSCP shell, which provides convenient control of the
208          sampler from the command line by providing LSCP aware features.
209        - VirtualMidiDevice: Added support for program change.
210        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
211        - VirtualMidiDevice: Added support for pitch bend.
212        - Aftertouch: extended API to explicitly handle channel pressure and
213          polyphonic key pressure events (so far polyphonic pressure was not
214          supported at all, and channel pressure was rerouted as CC128 but not
215          used so far).
216        - Added initial support for real-time instrument scripts. The script VM
217          code is shared by all sampler engine implemementations, however only the
218          gig file format currently provides support for storing instrument scripts
219          (as LinuxSampler extension to the original GigaStudio 4 format).
220    
221      * Gigasampler format engine:
222        - implemented the "round robin keyboard" dimension
223        - fixed round robin and random dimensions for cases when number of
224          dimension zones is not a power of two
225        - made round robin use a counter for each region instead of each
226          key
227        - bugfix: pitch LFO controller "internal+aftertouch" was broken
228        - bugfix: filter keyboard tracking was broken
229        - filter performance fix (an unnecessary copy was made of the
230          filter parameters in each sub fragment)
231        - handle special case when pan parameter in gig file has max or
232          min value
233        - Exclusive Groups: don't ever stop voices of the same note,
234          doesn't sound naturally with a drumkit
235        - fixed EG1 modulation when attack or release is zero
236        - Fixed support for 'aftertouch' attenuation controller.
237        - Fixed crash that happened with velocity split sounds under certain

247        - added support for trigger=first, trigger=legato and sw_previous
248        - allow non-numerical key values ("C#4" for example)
249        - "key" opcode now sets pitch_keycenter too
250        - fixed error when unloading instrument with same sample used by
251          multiple regions

258        - added support for amp_veltrack and amp_velcurve_N
259        - fine-tuned the default velocity curve
260        - added support for transpose
261        - fixed crash when using sw_down/up
262        - improved logic for sw_lokey/hikey/up/down/last
263        - added more v1 aliases to parser
264        - reduced memory usage for sfz data
265        - RT-safeness: avoid malloc in audio thread
266        - fixed a bug that could cause voice stealing to fail
267        - optimized sample lookup
268        - improved support for exclusive groups (group, off_by and

274        - use loop markers from sample file if loop_start and loop_end are
275          not set in sfz file
276        - implemeted filters. Filter types: lowpass, bandpass, bandreject

278          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
279          cutoff_cc, cutoff_chanaft.
280        - bugfix: zero ampeg_sustain didn't work
281        - added support for velocity effect on amplifier envelope time

416        - AU bugfix: failed to destroy its audio/MIDI devices
417        - Listen to all interfaces on Mac OS X (INADDR_ANY)
418        - VST bugfix: If the host called resume() before and after
419          changing sample rate or block size, the number of channels was
420          incorrectly set to two. This caused silence in Cubase 5.
421        - save engine type (gig, sfz or sf2) in plugin state
422        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
423          64 bit Windows
424        - AU: changed number of output channels from one stereo to 16
425          stereo

439        - VST: fixed crashes on Linux Ardour and EnergyXT
440        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

453        - Changed instrument editor plugin interface, providing additional
454          informations like the EngineChannel for which the instrument editor was
455          spawned for. This allows the instrument editors to interact more actively
456          with the sampler.
457    
458      * MIDI driver:
459        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
460          the ALSA sequencer client name

462          there is no reason for this limit
463        - MME: fixed memory handling bug found with cppcheck
464        - MME: removed compiler warning
465        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
466          which allows to retrieve the list of CoreMIDI clients / ports and to connect
467          to them a la JACK, via the usual sampler APIs
468        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
469          the driver will automatically connect to other CoreMIDI clients' ports

476        - Implemented missing handling of MIDI "running status".
477        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
478        - MME bugfix: driver wasn't closed properly
479        - CoreMIDI: automatically connect to all input sources by default (driver
480          parameter "AUTO_BIND").
481        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
482        - CoreMIDI: fixed minor memory leak
483    
484      * audio driver:
485        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
486        - JACK audio: react on sample rate changes.

489          RT context.
490        - ASIO driver: removed compiler warnings
491        - CoreAudio: fixed minor error handling bug
492        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
493        - JACK audio: return the JACK server's current sample rate as default value
494          for audio device parameter "SAMPLERATE" (fixes #166).
495

604          type while an instrument load was in progress
605        - bugfix: playing a note while changing the instrument could cause
606          a crash, or give "Handing back unknown region" error messages
607        - bugfix: calling SET VOICES (which Fantasia does on start and
608          refresh) could cause instruments to be unloaded
609        - Mac OS X: fixed name collision of enum in EffectControl and
610          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
611        - Mac OS X: fixed hanging threads
612        - Windows: disabled the previous thread fix on non-Mac systems, as
613          it caused hanging threads on Windows
614        - Fixed possible crashes due to corrupted MIDI/audio device list
615          after MIDI/audio device creation failure
616        - When creating MIDI instrument map entries with "PERSISTENT" type, the
617          instruments were uselessly precached with zero samples, however it still
618          took the full preloading time and on 1st program change the respective
619          instrument was completely reloaded again.
620        - fixed handling of rapid bank select and program change messages
621          sent to the same sampler channel (patch from the Open Octave
622          project, slightly adjusted)

635          introduced in previous fix)
636        - fixed crash when a channel received a program change while
637          playing a note in a key group
638        - fixed erroneous error message piping in VoiceBase.h
639          (labelled "Disk stream not available in time")
640        - Update effects on sample rate & period size changes (to avoid
641          crashes and noise on such transitions).
642        - ignore missing LADSPA paths without ignoring valid LADSPA paths
643          (fixes #208)
644        - Fixed bug in LSCP grammar definition which caused a statement like
645          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
646          practically irrelevant, however it caused problems with the new LSCP
647          shell's auto completion feature).
648        - Fixed MIDI program change messages being ignored if quickly executed
649          after each other (fixes #231).
650    
651    Version 1.0.0 (31 July 2009)
652    
653      * packaging changes:
654        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
655          causing e.g. the libgig test to fail when
656          "./configure --disable-jack-driver" was used
657          (patch by Alexis Ballier)
658        - fixed compilation with gcc 4.3
659        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
660        - fixed configure so it detects x86_64 (#107)
661        - fixes for building with newer MinGW versions

667          directory above)
668        - configure script fix: removed unconditional use of SSE
669        - fixed building with sqlite installed in a non-standard directory
670        - when cross-compiling, don't try to create instruments.db
671        - fix for new mingw-w64 version, which has usleep
672    
673      * general changes:
674        - bugfix: on some POSIX systems instrument editor plugins refused to

676          (fixes bug #70, patch by Ronald Baljeu)
677        - fixed endless loop which occured when loading an instrument editor
678          plugin DLL on Windows systems failed
679        - fixed memory leaks that occurred when liblinuxsampler was unloaded
680        - optimized the SynchronizedConfig class so it doesn't wait
681          unnecessarily long after an update
682        - added support for notifying instrument editors on note-on / note-off
683          events (e.g. to highlight the pressed keys on the virtual keyboard
684          of gigedit)
685        - added support for triggering notes by instrument editors (see above)
686        - be verbose on DLL load errors (on Linux)
687        - fixed di-harmonic triangle LFO implementation (this LFO implementation
688          is only used by very few systems, most pick the int math
689          implementation, which is usually faster)
690        - fixes for audio drivers with varying buffer sizes
691        - experimental support for running LinuxSampler as a DSSI, LV2 and
692          VST plugin
693        - notification events for stream/voice count statistics are now sent

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