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

199        - fine-tuned the default velocity curve
200        - added support for transpose
201        - fixed crash when using sw_down/up
202        - improved logic for sw_lokey/hikey/up/down/last
203        - added more v1 aliases to parser
204        - reduced memory usage for sfz data
205        - RT-safeness: avoid malloc in audio thread
206        - fixed a bug that could cause voice stealing to fail
207        - optimized sample lookup
208        - improved support for exclusive groups (group, off_by and

340          (modified patch which was originally posted by Sergey on LS mailing list)
341        - bugfix: generation of velocity curves etc should not be done
342          after each "#include", only after the main file is parsed
343        - bugfix: line numbers in error messages were wrong after "#include"
344        - added support for float and 32 bit sample files
345    
346      * SoundFont format engine:
347        - Initial implementation (not usable yet)

356        - AU bugfix: failed to destroy its audio/MIDI devices
357        - Listen to all interfaces on Mac OS X (INADDR_ANY)
358        - VST bugfix: If the host called resume() before and after
359          changing sample rate or block size, the number of channels was
360          incorrectly set to two. This caused silence in Cubase 5.
361        - save engine type (gig, sfz or sf2) in plugin state
362        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
363          64 bit Windows
364        - AU: changed number of output channels from one stereo to 16
365          stereo

371          the plugin was loaded a second time (#174)
372        - plugin bugfix: instrument loading hang when the plugin was
373          loaded a second time (this time it's for Linux and Mac, previous
374          similar fix was for Windows)
375        - thread safety fixes for the instrument loading thread
376        - LV2: use the new lv2 package if present
377        - VST: try to open Fantasia automatically on Linux and Mac too (on
378          Linux, the Fantasia jar should be placed in <prefix>/share/java)
379        - VST: fixed crashes on Linux Ardour and EnergyXT
380        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
381          port and audio channel routing for DSSI plugins are now visible.
382        - LV2: use urid and atom extensions instead of deprecated uri-map
383          and event
384        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
385        - LV2: changed number of output channels to 16 stereo, just like
386          the VST and AU plugins
387        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
388        - LV2: made LV2 plugin buildable on Windows and Mac
389        - VST: implemented retrieval and switching of programs using the
390          sampler's internal MIDI instrument mapping system
391    
392      * Instrument editor interface:
393        - Changed instrument editor plugin interface, providing additional
394          informations like the EngineChannel for which the instrument editor was
395          spawned for. This allows the instrument editors to interact more actively
396          with the sampler.
397    
398      * MIDI driver:
399        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
400          the ALSA sequencer client name

402          there is no reason for this limit
403        - MME: fixed memory handling bug found with cppcheck
404        - MME: removed compiler warning
405        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
406          which allows to retrieve the list of CoreMIDI clients / ports and to connect
407          to them a la JACK, via the usual sampler APIs
408        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
409          the driver will automatically connect to other CoreMIDI clients' ports

411        - added support for MIDI note on velocity filter
412        - CoreMIDI: fixed memory deallocation error
413        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
414          virtual keyboards in frontends / instrument editors being stuck.
415        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
416        - Implemented missing handling of MIDI "running status".
417        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
418        - MME bugfix: driver wasn't closed properly
419        - CoreMIDI: automatically connect to all input sources by default (driver
420          parameter "AUTO_BIND").
421        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
422        - CoreMIDI: fixed minor memory leak
423    
424      * audio driver:

429          RT context.
430        - ASIO driver: removed compiler warnings
431        - CoreAudio: fixed minor error handling bug
432        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

483        - Added support for moving cursor left/right with arrow keys.
484        - Added support for built-in LSCP reference documentation, which will
485          automatically show the relevant LSCP reference section on screen as soon
486          as one specific LSCP command was detected while typing on the command

507        - Added extended script VM for the Gigasampler/GigaStudio format sampler
508          engine, which extends the general instrument script VM with Giga format

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

575          introduced in previous fix)
576        - fixed crash when a channel received a program change while
577          playing a note in a key group
578        - fixed erroneous error message piping in VoiceBase.h
579          (labelled "Disk stream not available in time")
580        - Update effects on sample rate & period size changes (to avoid
581          crashes and noise on such transitions).
582        - ignore missing LADSPA paths without ignoring valid LADSPA paths
583          (fixes #208)
584        - Fixed bug in LSCP grammar definition which caused a statement like
585          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
586          practically irrelevant, however it caused problems with the new LSCP
587          shell's auto completion feature).
588        - Fixed MIDI program change messages being ignored if quickly executed
589          after each other (fixes #231).
590    
591    Version 1.0.0 (31 July 2009)
592    
593    * packaging changes:    * packaging changes:
594        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
595          causing e.g. the libgig test to fail when
596          "./configure --disable-jack-driver" was used
597          (patch by Alexis Ballier)
598        - fixed compilation with gcc 4.3

605        - Windows: look for editor plugins and Fantasia using base
606          directory of liblinuxsampler dll (look in the same directory and one
607          directory above)
608        - configure script fix: removed unconditional use of SSE
609        - fixed building with sqlite installed in a non-standard directory
610        - when cross-compiling, don't try to create instruments.db
611        - fix for new mingw-w64 version, which has usleep
612    
613      * general changes:
614        - bugfix: on some POSIX systems instrument editor plugins refused to

616          (fixes bug #70, patch by Ronald Baljeu)
617        - fixed endless loop which occured when loading an instrument editor
618          plugin DLL on Windows systems failed
619        - fixed memory leaks that occurred when liblinuxsampler was unloaded
620        - optimized the SynchronizedConfig class so it doesn't wait
621          unnecessarily long after an update
622        - added support for notifying instrument editors on note-on / note-off
623          events (e.g. to highlight the pressed keys on the virtual keyboard
624          of gigedit)
625        - added support for triggering notes by instrument editors (see above)
626        - be verbose on DLL load errors (on Linux)
627        - fixed di-harmonic triangle LFO implementation (this LFO implementation
628          is only used by very few systems, most pick the int math
629          implementation, which is usually faster)
630        - fixes for audio drivers with varying buffer sizes
631        - experimental support for running LinuxSampler as a DSSI, LV2 and
632          VST plugin
633        - notification events for stream/voice count statistics are now sent

636          multi-core and multi-cpu systems
637        - maximum voices and disk streams can now be altered at runtime
638        - fixed CPU feature detection on x86_64 (maybe fixes #108)
639        - automatic stacktrace mechanism is now turned off by default and can
640          be switched on by command line option "--stacktrace" (the automatic
641          stacktrace mechanism seems to be broken on most systems at the moment)
642        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
643          a pointer to the launched InstrumentEditor object
644        - added optional 3rd party user data parameter for following
645          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
646          InstrumentEditor::Launch(),
647          InstrumentManager::LaunchInstrumentEditor()
648        - theoretical fix: made SynchronizedConfig follow C++0x memory
649          model more strictly
650        - fixes for using large audio device buffers
651        - Windows: add the installation directory to the DLL search path
652          when loading an editor plugin (solves problems with VST and
653          gigedit on systems with other GTK versions installed)
654        - updated linuxsampler man page
655    
656      * audio driver:
657        - removed the nonsense audio channel constraint (which was hard coded to
658          max. 100 audio channels) for most audio drivers
659        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
660          opposed to the LSCP specs
661        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
662          reflected the wrong value
663        - fixed a memory management bug in ASIO driver
664        - Makefile fix: JACK_CFLAGS wasn't used
665        - JACK: use jack_client_open instead of the deprecated
666          jack_client_new
667        - added (experimental) CoreAudio driver
668        - applied old fixes to the ASIO driver that were included in the
669          previous binary release but accidentally never committed to CVS
670          (fixes #117)
671        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
672          win64)
673        - VST: added support for sample rate and buffer size changes
674        - VST: close editor (Fantasia) when the VST is removed
675        - VST: avoid opening Fantasia more than once for each VST instance
676        - VST: export main function as "main" on Linux too (fix for
677          energyXT)
678        - VST: changed number of output channels from one stereo to 16
679          stereo
680        - added channel routing, fxsends and midi maps to the settings
681          stored in the plugin state
682        - performance optimization of AudioChannel::MixTo() and
683          AudioChannel::CopyTo() methods using GCC vector exensions
684          (if available)
685        - ASIO fixes: avoid initializing the device twice, avoid throwing
686          exception when getting parameters from a disconnected device
687    
688      * MIDI driver:
689        - added JACK MIDI driver
690        - dispatch bank select as ordinary CC as well, the user might seriously
691          want to (mis)use it for some purpose ("fixed" in all current MIDI
692          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
693        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
694          CoreMidi or AU
695        - fixed mingw-w64 compilation error in MME driver
696        - made program change handling in MIDI thread real-time safe by
697          moving the logic to a non-RT thread
698        - fixed minor memory leak in ALSA driver

704        - Implemented option for adding instruments in separate directories
705          in the instruments database
706          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
707        - work-around for missing fnmatch function on Windows to make
708          instrument database compilable
709        - added instrument database support on Windows
710          works with both standalone mode and VST plugin.
711          the instruments DB file is located in
712          %USERPROFILE%\.linuxsampler\instruments.db which allows different
713          databases for each windows user
714          if no DB is present it automatically creates the .linuxsampler subdir
715          and then creates an empty DB
716        - fixed recursive import, which was broken on Windows
717    
718      * Gigasampler format engine:
719        - fixed a memory leak that could happen when a channel was deleted
720          while notes were playing
721        - made it possible to load an instrument even if the audio thread
722          isn't running
723        - added partial support for the "Controller Triggered" MIDI rule,
724          enough for piano gigs with pedal noise samples
725        - minor fix: only mark FX sends as being modified if really the
726          respective FX send MIDI controller was used
727        - added support for GM global device volume SysEx message
728          (can be selected at compile time to either apply globally to the
729          whole sampler [default] or only to the sampler channels that are
730          connected to the respective MIDI input port the SysEx message arrived
731          on)
732        - bugfix: notes triggered at position 0 in the audio buffer were
733          sometimes wrongly killed in the same buffer, causing no sound to
734          be played
735        - added support for chromatic / drumkit mode Roland GS Sysex message
736          which is usally used to switch a part between chromatic sounds and
737          drumkit sounds (as opposed to their common default setting of MIDI
738          part 10 being a drumkit part and all other ones chromatic parts), in
739          LS however one can switch between the first 16 MIDI instrument maps
740          defined for the sampler
741        - made it possible to create multiple sample channels even if the
742          audio thread isn't running
743        - fixed crash when removing channel with active voices (#116)
744        - bugfix: on sample reference changes (instrument editor), only
745          un-cache the respective sample if it's really not used by any
746          sampler engine anymore
747        - re-cache samples in case they were changed by an instrument editor,
748          e.g. when a sample was added while playing (#82)
749        - fixed hanging notes which occured when note-off event had the exact
750          same time stamp as the voice's note-on event and occured both in the
751          same audio fragment cycle (fixes bug #112)
752        - added support for the "fine tune" and "pitch bend range"
753          instrument-level gig parameters
754        - fixed minor artifacts in pitch bend handling
755        - added support for GS Reset SysEx message
756        - allow gig files to use unlimited downward pitch shifting
757        - added a limit check for upward pitch shifting
758        - bugfix: sometimes, when playing a note twice fast, the second
759          note was silent
760        - fixed crash happening when a pitch bend event arrived at the
761          same time a new instrument was loading
762    
763      * LSCP server:
764        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
765          react on MIDI data arriving on certain sampler channels (so far only
766          Note-On and Note-Off events are sent via this LSCP event)
767        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
768          react on MIDI data arriving on certain MIDI input devices (so far only
769          Note-On and Note-Off events are sent via this LSCP event)
770        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
771          SET DB_INSTRUMENT FILE_PATH
772        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
773          frontends to send MIDI messages to specific sampler channel
774        - added two additional fields to GET FILE INSTRUMENT INFO command -
775          KEY_BINDINGS and KEYSWITCH_BINDINGS
776        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
777          was incorrect
778        - Optimized the retrieval of the MIDI instrument mappings
779        - added new LSCP command "SET VOICES" to globally alter the maximum
780          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
781          be triggered respectively
782        - added new LSCP command "SET STREAMS" to globally alter the maximum
783          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
784          which will be triggered respectively
785        - bugfix: retry if "select" returns EINTR (this fixes a crash when
786          a gigedit file dialog is opened)
787        - close all connections when LSCPServer is deleted
788        - hard close of all sockets on exit
789        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
790          driver
791    
792      * Bug fixes:
793        - fixed a crash which occurs when removing a sampler channel waiting
794          to start instrument loading after another channel
795        - fixed a crash which occurs when removing a sampler channel with
796          instrument loading in progress (bug #113)
797        - fixed termination caused by uncaught exception when adding MIDI
798          instrument with PERSISTENT load mode
799        - fixed possible iterator invalidations when resetting the sampler
800        - fixed memory leaks when issuing the following LSCP commands:
801          GET AUDIO_OUTPUT_DRIVER INFO
802          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
803          GET MIDI_INPUT_DRIVER INFO
804          GET MIDI_INPUT_DRIVER_PARAMETER INFO
805        - fixed possible compilation error when sqlite is not present
806        - fixed orphaned pointers when setting maximum voices limit (bug #118)
807        - fixed crash when changing the audio output device of a sampler
808          channel with loaded instrument and start playing notes
809        - fixed endless loop in Engine::SuspendAll() (bug #120)
810        - fixed a low-level atomic load function that was broken on 64-bit
811          PowerPC, which probably could cause crashes on that platform
812        - fixed a memory management error which could cause a crash when a
813          plugin was unloaded
814        - bugfix: two private structs had the same name, which could cause
815          problems if the linker chose the wrong constructor
816        - fixed low-level ConditionServer usage bug that caused lockups on
817          Windows
818    
819    
820    Version 0.5.1 (6 December 2007)
821    
822      * packaging changes:
823        - added autoconf checks for pthread library
824        - added autoconf check for pthread bug found on certain NPTL-enabled
825          glibc versions (see Gentoo bug report #194076)
826        - added autoconf checks for MS Windows
827    
828      * general changes:
829        - bugfix: the thread used by an editor plugin didn't die when the
830          editor closed
831        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
832          out all the space. operator--() did not apply size_mask after
833          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
834          order to avoid problems with the _NonVolatileReader functions.
835        - bugfix: Stream.h: added a missing divide by BytesPerSample in
836          GetWriteSpace(). Since this function is currently only used in
837          the stream's qsort() compare function, it didn't trigger any
838          bugs.
839        - Resampler.h, Synthesizer.h: cubic interpolation now works in
840          24bit mode too. Faster method to read 24bit words on little
841          endian machines (x86): replaced 3 byte reads + shifts with a 1
842          unaligned 32bit read and shift
843        - experimental support for MS Windows (MIDI input via MME, AUDIO
844          output via ASIO)
845        - made handling of SIGINT signal (Ctrl-C) a bit more robust
846        - support for monitoring the total number of active disk streams
847          (new LSCP commands: GET TOTAL_STREAM_COUNT,
848          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
849    
850      * AUDIO driver:
851        - added Windows ASIO low latency audio driver
852    
853      * MIDI driver:
854        - added MME Windows MIDI driver
855    
856      * LSCP server:
857        - added support for Windows style path / filenames, however with
858          forward slash path separators instead of backslash
859          (i.e. "C:/foo/bar.gig")
860        - allow naughty liblscp to send non-string device parameters within
861          apostrophes as well
862        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
863          "LIST FILE INSTRUMENTS <file>" and
864          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
865          about an arbitrary instrument file on the system where the sampler is
866          running on
867    
868    Version 0.5.0 (15 October 2007)
869    
870      * packaging changes:
871        - config.h is not going to be installed along with liblinuxsampler's
872          API header files anymore
873        - only the API relevant header (and source) files will be exported to
874          the Doxygen API documentation (explicitly listed in Doxyfile.in)
875        - added completely new XCode project files for Mac OSX which is now
876          capable to execute our autoconf environment, thus no need anymore
877          to maintain the compile time configuration file (osx/version.h) for
878          OSX manually (patch by Toshi Nagata)
879        - fixed buggy boolean --enable-foo / --disable-foo configure script
880          parameters
881        - global.h now only covers global definitions that are needed for the
882          C++ API header files, all implementation internal global definitions
883          are now in global_private.h
884        - atomic.h is not exposed to the C++ API anymore
885        - no need to include config.h anymore for using LS's API header files
886        - fixed warnings in API doc generation
887    
888      * general changes:
889        - replaced the old, confusing MIDI program change mechanism by a
890          flexible MIDI instrument mapper which allows to map arbitrary
891          (MIDI bank, MIDI program) pairs with arbitrary
892          (engine type, instrument file, file index) triplets which will be
893          loaded on the respective channel when such MIDI program change
894          messages arrive, beside that, each entry allows to define a life-time
895          strategy for the instrument, so the user can define whether the
896          instrument should i.e. be permanently loaded (to be able to switch
897          quickly among sounds) or i.e. loaded just on demand when the
898          respective program change arrives (to safe RAM space), as well as a
899          global volume factor for each entry, so the user can adjust the volume
900          dynamic of his mapped instrument collection without having to modify
901          the instrument files, also one can manage arbitrary amount of such
902          MIDI instrument maps and assign each sampler channel individually
903          a certain map, so that i.e. separation of normal instruments and
904          drumkits is possible
905        - new notification events for tracking changes to audio/MIDI devices,
906          MIDI instrument maps, MIDI instruments, FX sends, global volume.
907        - sampler was limited to load max. 200 instruments in the background
908          due to a constant size RingBuffer FIFO which is now replaced by a
909          dynamic (unlimited) size std::list FIFO
910        - added FX sends, these allow to route audio signals to arbitrary audio
911          output channels for being processed by external effect processors
912          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
913          controllers
914        - global (sampler wide) volume can now be controlled at runtime
915        - Implemented new, improved notification system
916        - fixed compilation errors regarding OSX
917          (patch by Toshi Nagata)
918        - implemented instruments database
919        - added support for escape sequences to the instruments database
920        - added highly experimental support for on-the-fly instrument editing
921          within the sampler's process (by using instrument editor plugins),
922          you'll notice the new "Registered instrument editors:" message on
923          startup, added a new LSCP command:
924          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
925          to spawn a matching instrument editor for the instrument on the
926          given sampler channel, the plugin path can be overridden at compile
927          time with ./configure --enable-plugin-dir=/some/dir
928        - added experimental code for synchronizing instrument editors hosted
929          in the sampler's process to safely edit instruments while playing
930          without a crash (hopefully) by either suspending single regions
931          wherever possible or if unavoidable whole engine(s)
932        - fixed several issues in fundamental "Thread" class: set scheduling
933          policy and priority on thread level, set a minimum stack size for
934          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
935          threads simply inherited properties of starting thread instead of
936          setting their own policy and priority
937        - minor fix in our automatic stack trace mechanism on crashes, the
938          main process did not wait for the stack trace process to finish
939          its output
940        - fixed some minor memory leaks
941        - reenabled assembly features support, at the moment only for
942          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
943        - minor assembly fix in x86 features detection (don't use the PIC
944          register, to avoid relocations in the text segment at runtime)
945        - POSIX callback functions of Thread.h are hidden
946    
947      * MIDI driver:
948        - dispatch bank select (MSB and LSB) messages
949    
950      * audio driver:
951        - the ALSA audio output driver parameters now reflect the correct
952          parameter value ranges for the respective selected sound card
953          (patch by Till Wimmer, a bit fixed and extended)
954    
955      * Gigasampler format engine:
956        - if a filter is used and EG2 finishes before EG1, let the voice
957          die when EG2 has finished (this fixes a problem with clicks and
958          voice starvation for some gigs)
959        - playback is no longer disabled during instrument loading
960        - all notes playing on a channel that changes its instrument keep
961          playing with the old instrument until they get a note off
962          command
963        - EG fix: a release value of zero could cause noises or crash
964        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
965        - EG fine tuning: when attack is zero the EG starts at a level
966          above max sustain level, which means that there is a decay phase
967          even if sustain is 100%
968        - more EG fixes: the level could sometimes go below zero and cause
969          noises or crashes
970        - minor fix of EGDecay (patch by Toshi Nagata)
971        - fixed compiler error when --enable-override-filter-type was
972          supplied to the configure script (fixes #46)
973        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
974          instead of a fix value
975        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
976          127 (solo mode) only kill voices if the respective mode really
977          changed
978    
979      * LSCP server:
980        - fixed compile time error for old Bison versions
981          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
982        - parser now supports extended ASCII character set
983          (up to ASCII code 255, i.e. includes now umlauts and accents)
984        - filename arguments in LSCP commands now allow to use escape
985          sequences, that is directly literal as one of: \', \", \\, \n, \r,
986          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
987          code value like \xf2) (fixes bug #24)
988        - the following LSCP commands now also support escape sequences for at
989          least one of their text-based parameters (i.e. name, description):
990          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
991          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
992          "SET DB_INSTRUMENT_DIRECTORY NAME",
993          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
994          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
995          "FIND DB_INSTRUMENT_DIRECTORIES"
996        - returns verbose syntax errors (line and column where syntax error
997          occured, the unexpected character and the actually expected, possible
998          character(s), the latter only if less than 5 possibilities)
999        - made sure that LSCP syntax is not affected by gigedit locale
1000          settings
1001        - bugfix regarding strings parameter lists: all comma separated lists
1002          of strings were treated as being one string containing commas
1003          (fixes #57)
1004    
1005      * Bug fixes:
1006        - fixed crash occurring on certain LSCP scripts (Bug 39)
1007        - another thread safety fix for lscp "load engine" and "set
1008          channel audio output device"
1009        - fixed a crash which occurs when reassigning the same engine
1010          on a sampler channel with connected MIDI device
1011        - fixed a crash which occurs when changing the number of ports of a MIDI
1012          device connected to a sampler channel to number less then or equal
1013          to the index of the port to which the sampler channel is connected.
1014        - The previous bindings were not been disconnected when altering
1015          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1016          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1017        - The active stream/voice count statistic was incorrect.
1018        - notification events were not been sent for some sampler
1019          channel changes
1020        - added default min and max values to restrict the number of allowed
1021          audio output channels and MIDI input ports
1022        - the connection to the PCM interface is now closed when destroying
1023          an audio output device
1024        - files with slash in their path or filename could not be loaded
1025    
1026      * test cases:
1027        - updated and fixed (haven't been touched in a while)
1028    
1029    Version 0.4.0 (24 November 2006)
1030    
1031      * packaging changes:
1032        - changed deprecated copyright attribute to license; added ldconfig
1033          to post-(un)install steps; added devel package for liblinuxsampler;
1034          to linuxsampler.spec (RPM)

1083        - added support for the "attenuation controller threshold" gig
1084          parameter
1085        - added smoothing of volume changes caused by control change
1086          messages
1087        - sample loop parameters are now taken from the DimensionRegion
1088          instead of the wave chunk
1089        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1090          not equal to a power of two
1091        - reimplementation of the filter algorithm. The new filter is more
1092          accurate and supports all gig filter types, including bandreject
1093          and lowpass turbo.
1094        - real support for 24 bit samples - samples are not truncated to
1095          16 bits anymore
1096        - support for aftertouch (channel pressure, not polyphonic
1097          aftertouch)
1098        - LFO1 behaviour fixed (dampening from max volume instead of
1099          amplifying from 0)
