# 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    
24      * packaging changes:
25        - removed unnecessary dependency to libuuid
26          (originated by libgig's usage of it)
27    
28      * Real-time instrument scripts:
29        - Implemented scheduler for delayed MIDI events and for suspended scripts.
30        - Built-in script function "wait()": implemented support for function's
31          "duration-us" argument, thus scripts using this function are now
32          correctly resumed after the requested amount of microseconds.
33        - Built-in script function "play_note()": implemented support for
34          function's "duration-us" argument, thus notes triggered with this
35          argument are now correctly released after the requested amount of
36          microseconds.
37        - Fix: script events were not cleared when engine channel was reset,
38          potentially causing undefined behavior.
39        - Fixed crash which happened when trying to reference an undeclared
40          variable.
41        - Built-in script function "play_note()": Added support for passing
42          special value -1 for "duration-us" argument, which will cause the
43          triggered note to be released once the original note was released.
44    
45    Version 2.0.0 (15 July 2015)
46    
47      * packaging changes:
48        - fixed building with newer MinGW-w64
49        - Mac OS X: support the new dir for Core Audio SDK
50        - Mac OS X: fixed building outside source directory
51        - made sure all source files for hostplugins are included when
52          doing "make dist"
53        - removed empty directories left from the cvs to svn migration
54        - fixed compilation with gcc 4.6.1
55        - another "make dist" fix, for the LV2 plugin
56        - made --enable-pthread-testcancel default on Mac OS X
57        - minor Makefile fix for building lscpparser when build and source
58          directories are separate
59        - Mac OS X: made it possible to specify plugin installation dir to
60          configure
61        - Mac OS X: Makefile fix for the install-strip target
62        - fixed compilation with gcc 4.7
63        - fixed configure script error with old autoconf versions
64        - lsatomic.h: use gcc provided atomic functions if building with
65          gcc 4.7 and C++11
66        - modernized configure script
67        - fixed linkage error when building with
68          LDFLAGS="-Wl,--no-undefined" (#190)
69        - fixed compilation with Clang 3.2
70        - removed usage of deprecated Automake variable INCLUDES
71        - fixed building with C++11
72        - build fix: ChangeFlagRelaxed.h was missing in makefile
73        - build fix: libsndfile compiler flags were missing in some
74          makefiles
75        - fix for building with bison 3.0 (#202)
76        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
77          on the process's main thread
78        - fixed build error on newer MinGW
79        - support building with older jack versions
80        - support building with spaces in vst sdk path
81        - enabled automake 'subdir-objects' option and moved external
82          source references (vst, au, asio) from makefiles to cpp files,
83          in order to get rid of warnings from automake 1.14
84    
85      * general changes:
86        - Refactoring: moved the independent code from
87          the Gigasampler format engine to base classes
88        - command line option '--profile' is currently disabled, since the
89          respective profiling code is currently broken
90        - Introduced support for optional environment variable
91          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
92          where the sampler shall look for instrument editor plugins
93          (patch by Luis Garrido, slightly modified).
94        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
95        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
96        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
97          note (in this implementation of the sampler its simply hard routed to
98          the 1st effect send of the sampler channel, no matter what the actual
99          effect type is)
100        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
101          note (in this implementation of the sampler its simply hard routed to
102          the 2nd effect send of the sampler channel, no matter what the actual
103          effect type is)
104        - implemented support for internal LADSPA effects
105        - raised limit of program change queue from 100 to 512
106          (as suggested by Alex Stone)
107        - implemented sine LFO, pulse LFO and saw LFO
108        - experimental support for per voice equalization
109        - added command line option --exec-after-init
110        - Introduced new C++ API method:
111          EngineChannel::InstrumentFileName(int index)
112          allowing to retrieve the whole list of files used for the loaded
113          instrument on an engine channel (a.k.a. part). Some GigaStudio
114          instruments for example are splitted over several files like
115          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
116        - Added new C++ API method Sampler::GetGlobalMaxVoices().
117        - Added new C++ API method Sampler::GetGlobalMaxStreams().
118        - Added new C++ API method Sampler::SetGlobalMaxVoices().
119        - Added new C++ API method Sampler::SetGlobalMaxStreams().
120        - Various "const" and "restrict" optimizations.
121        - all engines: add pan CC value to instrument pan parameter before
122          applying panning, instead of using two separate pan functions in
123          series (#182)
124        - added a lock guard class for exception safe mutex handling and
125          used it everywhere appropriate
126        - Immediately apply scale tuning changes to active voices.
127        - Exposed scale tuning to C++ API (along to the already existing standard
128          SysEx way).
129        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
130          and broken for ppc64. (Seq_cst loads and stores are actually not
131          used in LS, so the bug wasn't noticable.)
132        - lsatomic.h: added ARMv7 support
133        - Added support for multiple MIDI input ports per sampler channel (and
134          added various new C++ methods for this new feature / design change, old
135          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
136          as deprecated but are still there and should provide full behavior
137          backward compatibility).
138        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
139          unsafe and caused compilation error with clang 2.x).
140        - Bugfix: only process the latest MIDI program change event.
141        - Introducing the LSCP shell, which provides convenient control of the
142          sampler from the command line by providing LSCP aware features.
143        - VirtualMidiDevice: Added support for program change.
144        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
145        - VirtualMidiDevice: Added support for pitch bend.
146        - Aftertouch: extended API to explicitly handle channel pressure and
147          polyphonic key pressure events (so far polyphonic pressure was not
148          supported at all, and channel pressure was rerouted as CC128 but not
149          used so far).
150        - Added initial support for real-time instrument scripts. The script VM
151          code is shared by all sampler engine implemementations, however only the
152          gig file format currently provides support for storing instrument scripts
153          (as LinuxSampler extension to the original GigaStudio 4 format).
154    
155      * Gigasampler format engine:
156        - implemented the "round robin keyboard" dimension
157        - fixed round robin and random dimensions for cases when number of
158          dimension zones is not a power of two
159        - made round robin use a counter for each region instead of each
160          key
161        - bugfix: pitch LFO controller "internal+aftertouch" was broken
162        - bugfix: filter keyboard tracking was broken
163        - filter performance fix (an unnecessary copy was made of the
164          filter parameters in each sub fragment)
165        - handle special case when pan parameter in gig file has max or
166          min value
167        - Exclusive Groups: don't ever stop voices of the same note,
168          doesn't sound naturally with a drumkit
169        - fixed EG1 modulation when attack or release is zero
170        - Fixed support for 'aftertouch' attenuation controller.
171        - Fixed crash that happened with velocity split sounds under certain
172          conditions (see also previous commit on libgig).
173        - fixed behaviour of filter LFO
174    
175      * SFZ format engine:
176        - Initial implementation (not usable yet)

178        - added a fine-tuned v1 envelope generator instead of using the
179          one from the gig engine
180        - fixed memory leak and memory handling errors
181        - added support for trigger=first, trigger=legato and sw_previous
182        - allow non-numerical key values ("C#4" for example)
183        - "key" opcode now sets pitch_keycenter too
184        - fixed error when unloading instrument with same sample used by
185          multiple regions

193        - fine-tuned the default velocity curve
194        - added support for transpose
195        - fixed crash when using sw_down/up
196        - improved logic for sw_lokey/hikey/up/down/last
197        - added more v1 aliases to parser
198        - reduced memory usage for sfz data
199        - RT-safeness: avoid malloc in audio thread

205        - added support for loop_mode=one_shot
206        - fixed playback of 16 bit wav files on big endian CPUs
207        - added support for Ogg Vorbis sample files
208        - use loop markers from sample file if loop_start and loop_end are
209          not set in sfz file

335        - bugfix: generation of velocity curves etc should not be done
336          after each "#include", only after the main file is parsed
337        - bugfix: line numbers in error messages were wrong after "#include"
338        - added support for float and 32 bit sample files
339    
340      * SoundFont format engine:
341        - Initial implementation (not usable yet)
342        - RT-safeness: avoid malloc in audio thread
343        - fixed a bug that could cause voice stealing to fail
344        - fine-tuned amplitude EG (by switching from gig to sfz EG)
345        - initial implementation of Vibrato LFO and Modulation LFO
346        - initial implementation of cutoff filter
347        - use linear decay and release for filter and pitch EG
348    
349      * Host plugins (VST, AU, LV2, DSSI):
350        - AU bugfix: failed to destroy its audio/MIDI devices
351        - Listen to all interfaces on Mac OS X (INADDR_ANY)
352        - VST bugfix: If the host called resume() before and after
353          changing sample rate or block size, the number of channels was
354          incorrectly set to two. This caused silence in Cubase 5.
355        - save engine type (gig, sfz or sf2) in plugin state
356        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
357          64 bit Windows
358        - AU: changed number of output channels from one stereo to 16
359          stereo
360        - VST: made it possible to build the VST plugin for Mac
361        - AU: link AU plugin dynamically if --disable-shared isn't
362          specified

365          the plugin was loaded a second time (#174)
366        - plugin bugfix: instrument loading hang when the plugin was
367          loaded a second time (this time it's for Linux and Mac, previous
368          similar fix was for Windows)
369        - thread safety fixes for the instrument loading thread
370        - LV2: use the new lv2 package if present
371        - VST: try to open Fantasia automatically on Linux and Mac too (on
372          Linux, the Fantasia jar should be placed in <prefix>/share/java)
373        - VST: fixed crashes on Linux Ardour and EnergyXT
374        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
375          port and audio channel routing for DSSI plugins are now visible.
376        - LV2: use urid and atom extensions instead of deprecated uri-map
377          and event
378        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
379        - LV2: changed number of output channels to 16 stereo, just like
380          the VST and AU plugins
381        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
382        - LV2: made LV2 plugin buildable on Windows and Mac
383        - VST: implemented retrieval and switching of programs using the
384          sampler's internal MIDI instrument mapping system
385    
386      * Instrument editor interface:
387        - Changed instrument editor plugin interface, providing additional
388          informations like the EngineChannel for which the instrument editor was
389          spawned for. This allows the instrument editors to interact more actively
390          with the sampler.
391    
392      * MIDI driver:
393        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
394          the ALSA sequencer client name
395        - removed limit of maximum amount of MIDI ports per MIDI device, since
396          there is no reason for this limit
397        - MME: fixed memory handling bug found with cppcheck
398        - MME: removed compiler warning
399        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
400          which allows to retrieve the list of CoreMIDI clients / ports and to connect
401          to them a la JACK, via the usual sampler APIs
402        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
403          the driver will automatically connect to other CoreMIDI clients' ports
404          (e.g. external MIDI devices being attached to the Mac)
405        - added support for MIDI note on velocity filter
406        - CoreMIDI: fixed memory deallocation error
407        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
408          virtual keyboards in frontends / instrument editors being stuck.
409        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
410        - Implemented missing handling of MIDI "running status".
411        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
412        - MME bugfix: driver wasn't closed properly
413        - CoreMIDI: automatically connect to all input sources by default (driver
414          parameter "AUTO_BIND").
415        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
416        - CoreMIDI: fixed minor memory leak
417    
418      * audio driver:
419        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
420        - JACK audio: react on sample rate changes.
421        - JACK audio: react on buffer size changes.

423          RT context.
424        - ASIO driver: removed compiler warnings
425        - CoreAudio: fixed minor error handling bug
426        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
427        - JACK audio: return the JACK server's current sample rate as default value
428          for audio device parameter "SAMPLERATE" (fixes #166).
429    
430      * LSCP server:
431        - added support for sending MIDI CC messages via LSCP command

466        - provide comprehensive error messages on LSCP syntax errors
467          (suggesting expected next non-terminal symbols)

477        - Added support for moving cursor left/right with arrow keys.
478        - Added support for built-in LSCP reference documentation, which will
479          automatically show the relevant LSCP reference section on screen as soon
480          as one specific LSCP command was detected while typing on the command
481          line.
482

499          or no argument).
500        - Implemented built-in script function "set_controller()".
501        - Added extended script VM for the Gigasampler/GigaStudio format sampler
502          engine, which extends the general instrument script VM with Giga format
503          specific variables and functions.
504        - Giga format scripts: added built-in script int constant variables

534        - minor valgrind fixes
535        - fixed crash which occurred when changing an already deployed sampler
536          channel to a different engine type
537        - fixed crash when deleting a sampler channel or changing engine
538          type while an instrument load was in progress
539        - bugfix: playing a note while changing the instrument could cause
540          a crash, or give "Handing back unknown region" error messages
541        - bugfix: calling SET VOICES (which Fantasia does on start and
542          refresh) could cause instruments to be unloaded
543        - Mac OS X: fixed name collision of enum in EffectControl and
544          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
545        - Mac OS X: fixed hanging threads
546        - Windows: disabled the previous thread fix on non-Mac systems, as
547          it caused hanging threads on Windows
548        - Fixed possible crashes due to corrupted MIDI/audio device list
549          after MIDI/audio device creation failure
550        - When creating MIDI instrument map entries with "PERSISTENT" type, the
551          instruments were uselessly precached with zero samples, however it still
552          took the full preloading time and on 1st program change the respective
553          instrument was completely reloaded again.
554        - fixed handling of rapid bank select and program change messages
555          sent to the same sampler channel (patch from the Open Octave
556          project, slightly adjusted)
557        - fixed crash when trying to create an effect instance with controls
558          which min and/or max values depend on the sample rate

564          (#176)
565        - more thread safety fixes for the instrument loading thread
566        - sfz/sf2 engine: fixed crash when using small audio fragment size
567        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
568        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
569          introduced in previous fix)
570        - fixed crash when a channel received a program change while
571          playing a note in a key group
572        - fixed erroneous error message piping in VoiceBase.h
573          (labelled "Disk stream not available in time")
574        - Update effects on sample rate & period size changes (to avoid
575          crashes and noise on such transitions).
576        - ignore missing LADSPA paths without ignoring valid LADSPA paths
577          (fixes #208)
578        - Fixed bug in LSCP grammar definition which caused a statement like
579          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
580          practically irrelevant, however it caused problems with the new LSCP
581          shell's auto completion feature).
582        - Fixed MIDI program change messages being ignored if quickly executed
583          after each other (fixes #231).
584    
585    Version 1.0.0 (31 July 2009)
586    
587      * packaging changes:
588        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
589          causing e.g. the libgig test to fail when
590          "./configure --disable-jack-driver" was used
591          (patch by Alexis Ballier)
592        - fixed compilation with gcc 4.3
593        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
594        - fixed configure so it detects x86_64 (#107)
595        - fixes for building with newer MinGW versions

599        - Windows: look for editor plugins and Fantasia using base
600          directory of liblinuxsampler dll (look in the same directory and one
601          directory above)
602        - configure script fix: removed unconditional use of SSE
603        - fixed building with sqlite installed in a non-standard directory
604        - when cross-compiling, don't try to create instruments.db
605        - fix for new mingw-w64 version, which has usleep
606    
607      * general changes:
608        - bugfix: on some POSIX systems instrument editor plugins refused to
609          load as we used a non-portable Linux specific struct field
610          (fixes bug #70, patch by Ronald Baljeu)
611        - fixed endless loop which occured when loading an instrument editor
612          plugin DLL on Windows systems failed
613        - fixed memory leaks that occurred when liblinuxsampler was unloaded
614        - optimized the SynchronizedConfig class so it doesn't wait
615          unnecessarily long after an update
616        - added support for notifying instrument editors on note-on / note-off
617          events (e.g. to highlight the pressed keys on the virtual keyboard
618          of gigedit)
619        - added support for triggering notes by instrument editors (see above)
620        - be verbose on DLL load errors (on Linux)
621        - fixed di-harmonic triangle LFO implementation (this LFO implementation
622          is only used by very few systems, most pick the int math
623          implementation, which is usually faster)
624        - fixes for audio drivers with varying buffer sizes
625        - experimental support for running LinuxSampler as a DSSI, LV2 and
626          VST plugin
627        - notification events for stream/voice count statistics are now sent
628          only when there are actual changes
629        - added memory ordering constraints to improve stability on
630          multi-core and multi-cpu systems
631        - maximum voices and disk streams can now be altered at runtime
632        - fixed CPU feature detection on x86_64 (maybe fixes #108)
633        - automatic stacktrace mechanism is now turned off by default and can
634          be switched on by command line option "--stacktrace" (the automatic
635          stacktrace mechanism seems to be broken on most systems at the moment)
636        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
637          a pointer to the launched InstrumentEditor object
638        - added optional 3rd party user data parameter for following
639          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
640          InstrumentEditor::Launch(),
641          InstrumentManager::LaunchInstrumentEditor()
642        - theoretical fix: made SynchronizedConfig follow C++0x memory
643          model more strictly
644        - fixes for using large audio device buffers
645        - Windows: add the installation directory to the DLL search path
646          when loading an editor plugin (solves problems with VST and
647          gigedit on systems with other GTK versions installed)
648        - updated linuxsampler man page
649    
650      * audio driver:
651        - removed the nonsense audio channel constraint (which was hard coded to
652          max. 100 audio channels) for most audio drivers
653        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
654          opposed to the LSCP specs
655        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
656          reflected the wrong value
657        - fixed a memory management bug in ASIO driver
658        - Makefile fix: JACK_CFLAGS wasn't used
659        - JACK: use jack_client_open instead of the deprecated
660          jack_client_new
661        - added (experimental) CoreAudio driver
662        - applied old fixes to the ASIO driver that were included in the
663          previous binary release but accidentally never committed to CVS
664          (fixes #117)
665        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
666          win64)
667        - VST: added support for sample rate and buffer size changes
668        - VST: close editor (Fantasia) when the VST is removed
669        - VST: avoid opening Fantasia more than once for each VST instance
670        - VST: export main function as "main" on Linux too (fix for
671          energyXT)
672        - VST: changed number of output channels from one stereo to 16
673          stereo
674        - added channel routing, fxsends and midi maps to the settings
675          stored in the plugin state
676        - performance optimization of AudioChannel::MixTo() and
677          AudioChannel::CopyTo() methods using GCC vector exensions
678          (if available)
679        - ASIO fixes: avoid initializing the device twice, avoid throwing
680          exception when getting parameters from a disconnected device
681    
682      * MIDI driver:
683        - added JACK MIDI driver
684        - dispatch bank select as ordinary CC as well, the user might seriously
685          want to (mis)use it for some purpose ("fixed" in all current MIDI
686          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
687        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
688          CoreMidi or AU
689        - fixed mingw-w64 compilation error in MME driver
690        - made program change handling in MIDI thread real-time safe by
691          moving the logic to a non-RT thread
692        - fixed minor memory leak in ALSA driver
693    
694      * instruments database:
695        - avoid time consuming samples scanning when adding instruments
696          to the instruments database
697        - added support for handling lost files in the instruments database
698        - Implemented option for adding instruments in separate directories
699          in the instruments database
700          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)

702          instrument database compilable
703        - added instrument database support on Windows
704          works with both standalone mode and VST plugin.
705          the instruments DB file is located in
706          %USERPROFILE%\.linuxsampler\instruments.db which allows different
707          databases for each windows user
708          if no DB is present it automatically creates the .linuxsampler subdir
709          and then creates an empty DB
710        - fixed recursive import, which was broken on Windows
711    
712      * Gigasampler format engine:
713        - fixed a memory leak that could happen when a channel was deleted
714          while notes were playing
715        - made it possible to load an instrument even if the audio thread
716          isn't running
717        - added partial support for the "Controller Triggered" MIDI rule,
718          enough for piano gigs with pedal noise samples
719        - minor fix: only mark FX sends as being modified if really the
720          respective FX send MIDI controller was used
721        - added support for GM global device volume SysEx message
722          (can be selected at compile time to either apply globally to the
723          whole sampler [default] or only to the sampler channels that are
724          connected to the respective MIDI input port the SysEx message arrived
725          on)
726        - bugfix: notes triggered at position 0 in the audio buffer were
727          sometimes wrongly killed in the same buffer, causing no sound to
728          be played
729        - added support for chromatic / drumkit mode Roland GS Sysex message
730          which is usally used to switch a part between chromatic sounds and
731          drumkit sounds (as opposed to their common default setting of MIDI
732          part 10 being a drumkit part and all other ones chromatic parts), in
733          LS however one can switch between the first 16 MIDI instrument maps
734          defined for the sampler
735        - made it possible to create multiple sample channels even if the
736          audio thread isn't running
737        - fixed crash when removing channel with active voices (#116)
738        - bugfix: on sample reference changes (instrument editor), only
739          un-cache the respective sample if it's really not used by any
740          sampler engine anymore
741        - re-cache samples in case they were changed by an instrument editor,
742          e.g. when a sample was added while playing (#82)
743        - fixed hanging notes which occured when note-off event had the exact
744          same time stamp as the voice's note-on event and occured both in the
745          same audio fragment cycle (fixes bug #112)
746        - added support for the "fine tune" and "pitch bend range"
747          instrument-level gig parameters
748        - fixed minor artifacts in pitch bend handling
749        - added support for GS Reset SysEx message
750        - allow gig files to use unlimited downward pitch shifting
751        - added a limit check for upward pitch shifting
752        - bugfix: sometimes, when playing a note twice fast, the second
753          note was silent
754        - fixed crash happening when a pitch bend event arrived at the
755          same time a new instrument was loading
756    
757      * LSCP server:
758        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
759          react on MIDI data arriving on certain sampler channels (so far only
760          Note-On and Note-Off events are sent via this LSCP event)
761        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
762          react on MIDI data arriving on certain MIDI input devices (so far only
763          Note-On and Note-Off events are sent via this LSCP event)
764        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
765          SET DB_INSTRUMENT FILE_PATH
766        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
767          frontends to send MIDI messages to specific sampler channel
768        - added two additional fields to GET FILE INSTRUMENT INFO command -
769          KEY_BINDINGS and KEYSWITCH_BINDINGS
770        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
771          was incorrect
772        - Optimized the retrieval of the MIDI instrument mappings
773        - added new LSCP command "SET VOICES" to globally alter the maximum
774          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
775          be triggered respectively
776        - added new LSCP command "SET STREAMS" to globally alter the maximum
777          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
778          which will be triggered respectively
779        - bugfix: retry if "select" returns EINTR (this fixes a crash when
780          a gigedit file dialog is opened)
781        - close all connections when LSCPServer is deleted
782        - hard close of all sockets on exit
783        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
784          driver
785    
786      * Bug fixes:
787        - fixed a crash which occurs when removing a sampler channel waiting
788          to start instrument loading after another channel
789        - fixed a crash which occurs when removing a sampler channel with
790          instrument loading in progress (bug #113)
791        - fixed termination caused by uncaught exception when adding MIDI
792          instrument with PERSISTENT load mode
793        - fixed possible iterator invalidations when resetting the sampler
794        - fixed memory leaks when issuing the following LSCP commands:
795          GET AUDIO_OUTPUT_DRIVER INFO
796          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
797          GET MIDI_INPUT_DRIVER INFO
798          GET MIDI_INPUT_DRIVER_PARAMETER INFO
799        - fixed possible compilation error when sqlite is not present
800        - fixed orphaned pointers when setting maximum voices limit (bug #118)
801        - fixed crash when changing the audio output device of a sampler
802          channel with loaded instrument and start playing notes
803        - fixed endless loop in Engine::SuspendAll() (bug #120)
804        - fixed a low-level atomic load function that was broken on 64-bit
805          PowerPC, which probably could cause crashes on that platform
806        - fixed a memory management error which could cause a crash when a
807          plugin was unloaded
808        - bugfix: two private structs had the same name, which could cause
809          problems if the linker chose the wrong constructor
810        - fixed low-level ConditionServer usage bug that caused lockups on
811          Windows
812    
813    
814    Version 0.5.1 (6 December 2007)
815    
816      * packaging changes:
817        - added autoconf checks for pthread library
818        - added autoconf check for pthread bug found on certain NPTL-enabled
819          glibc versions (see Gentoo bug report #194076)
820        - added autoconf checks for MS Windows
821    
822      * general changes:
823        - bugfix: the thread used by an editor plugin didn't die when the
824          editor closed
825        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
826          out all the space. operator--() did not apply size_mask after
827          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
828          order to avoid problems with the _NonVolatileReader functions.
829        - bugfix: Stream.h: added a missing divide by BytesPerSample in
830          GetWriteSpace(). Since this function is currently only used in
831          the stream's qsort() compare function, it didn't trigger any
832          bugs.
833        - Resampler.h, Synthesizer.h: cubic interpolation now works in
834          24bit mode too. Faster method to read 24bit words on little
835          endian machines (x86): replaced 3 byte reads + shifts with a 1
836          unaligned 32bit read and shift
837        - experimental support for MS Windows (MIDI input via MME, AUDIO
838          output via ASIO)
839        - made handling of SIGINT signal (Ctrl-C) a bit more robust
840        - support for monitoring the total number of active disk streams
841          (new LSCP commands: GET TOTAL_STREAM_COUNT,
842          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
843    
844      * AUDIO driver:
845        - added Windows ASIO low latency audio driver
846    
847      * MIDI driver:
848        - added MME Windows MIDI driver
849    
850      * LSCP server:
851        - added support for Windows style path / filenames, however with
852          forward slash path separators instead of backslash
853          (i.e. "C:/foo/bar.gig")
854        - allow naughty liblscp to send non-string device parameters within
855          apostrophes as well
856        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
857          "LIST FILE INSTRUMENTS <file>" and
858          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
859          about an arbitrary instrument file on the system where the sampler is
860          running on
