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

208        - added support for random, seq_position, seq_length and volume
209        - added v1 LFO opcodes to parser (no support in engine yet)
210        - added support for amp_veltrack and amp_velcurve_N
211        - fine-tuned the default velocity curve
212        - added support for transpose
213        - fixed crash when using sw_down/up
214        - improved logic for sw_lokey/hikey/up/down/last
215        - added more v1 aliases to parser
216        - reduced memory usage for sfz data
217        - RT-safeness: avoid malloc in audio thread
218        - fixed a bug that could cause voice stealing to fail
219        - optimized sample lookup
220        - improved support for exclusive groups (group, off_by and

340          used
341        - bugfix: looping was disabled if loop_start was set to 0
342        - allow regions with end=-1 to turn off other regions using the

352          (modified patch which was originally posted by Sergey on LS mailing list)
353        - bugfix: generation of velocity curves etc should not be done
354          after each "#include", only after the main file is parsed
355        - bugfix: line numbers in error messages were wrong after "#include"
356        - added support for float and 32 bit sample files
357    
358      * SoundFont format engine:

368        - AU bugfix: failed to destroy its audio/MIDI devices
369        - Listen to all interfaces on Mac OS X (INADDR_ANY)
370        - VST bugfix: If the host called resume() before and after
371          changing sample rate or block size, the number of channels was
372          incorrectly set to two. This caused silence in Cubase 5.
373        - save engine type (gig, sfz or sf2) in plugin state
374        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
375          64 bit Windows
376        - AU: changed number of output channels from one stereo to 16
377          stereo

387        - thread safety fixes for the instrument loading thread
388        - LV2: use the new lv2 package if present
389        - VST: try to open Fantasia automatically on Linux and Mac too (on
390          Linux, the Fantasia jar should be placed in <prefix>/share/java)
391        - VST: fixed crashes on Linux Ardour and EnergyXT
392        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
393          port and audio channel routing for DSSI plugins are now visible.

405        - Changed instrument editor plugin interface, providing additional
406          informations like the EngineChannel for which the instrument editor was
407          spawned for. This allows the instrument editors to interact more actively
408          with the sampler.
409    
410      * MIDI driver:
411        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
412          the ALSA sequencer client name

414          there is no reason for this limit
415        - MME: fixed memory handling bug found with cppcheck
416        - MME: removed compiler warning
417        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
418          which allows to retrieve the list of CoreMIDI clients / ports and to connect
419          to them a la JACK, via the usual sampler APIs
420        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
421          the driver will automatically connect to other CoreMIDI clients' ports

423        - added support for MIDI note on velocity filter
424        - CoreMIDI: fixed memory deallocation error
425        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
426          virtual keyboards in frontends / instrument editors being stuck.
427        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
428        - Implemented missing handling of MIDI "running status".
429        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
430        - MME bugfix: driver wasn't closed properly
431        - CoreMIDI: automatically connect to all input sources by default (driver
432          parameter "AUTO_BIND").
433        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
434        - CoreMIDI: fixed minor memory leak
435    
436      * audio driver:

441          RT context.
442        - ASIO driver: removed compiler warnings
443        - CoreAudio: fixed minor error handling bug
444        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

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

518        - Implemented built-in script function "set_controller()".
519        - Added extended script VM for the Gigasampler/GigaStudio format sampler
520          engine, which extends the general instrument script VM with Giga format

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

587          introduced in previous fix)
588        - fixed crash when a channel received a program change while
589          playing a note in a key group
590        - fixed erroneous error message piping in VoiceBase.h
591          (labelled "Disk stream not available in time")
592        - Update effects on sample rate & period size changes (to avoid
593          crashes and noise on such transitions).
594        - ignore missing LADSPA paths without ignoring valid LADSPA paths
595          (fixes #208)
596        - Fixed bug in LSCP grammar definition which caused a statement like
597          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
598          practically irrelevant, however it caused problems with the new LSCP
599          shell's auto completion feature).
600        - Fixed MIDI program change messages being ignored if quickly executed
601          after each other (fixes #231).
602    
603    Version 1.0.0 (31 July 2009)
604    
605      * packaging changes:
606        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
607          causing e.g. the libgig test to fail when
608          "./configure --disable-jack-driver" was used
609          (patch by Alexis Ballier)
610        - fixed compilation with gcc 4.3
611        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
612        - fixed configure so it detects x86_64 (#107)
613        - fixes for building with newer MinGW versions

617        - Windows: look for editor plugins and Fantasia using base
618          directory of liblinuxsampler dll (look in the same directory and one
619          directory above)
620        - configure script fix: removed unconditional use of SSE
621        - fixed building with sqlite installed in a non-standard directory
622        - when cross-compiling, don't try to create instruments.db
623        - fix for new mingw-w64 version, which has usleep
624    
625      * general changes:
626        - bugfix: on some POSIX systems instrument editor plugins refused to
627          load as we used a non-portable Linux specific struct field
628          (fixes bug #70, patch by Ronald Baljeu)
629        - fixed endless loop which occured when loading an instrument editor
630          plugin DLL on Windows systems failed
631        - fixed memory leaks that occurred when liblinuxsampler was unloaded
632        - optimized the SynchronizedConfig class so it doesn't wait
633          unnecessarily long after an update
634        - added support for notifying instrument editors on note-on / note-off
635          events (e.g. to highlight the pressed keys on the virtual keyboard
636          of gigedit)
637        - added support for triggering notes by instrument editors (see above)
638        - be verbose on DLL load errors (on Linux)
639        - fixed di-harmonic triangle LFO implementation (this LFO implementation
640          is only used by very few systems, most pick the int math
641          implementation, which is usually faster)
642        - fixes for audio drivers with varying buffer sizes
643        - experimental support for running LinuxSampler as a DSSI, LV2 and
644          VST plugin
645        - notification events for stream/voice count statistics are now sent
646          only when there are actual changes

648          multi-core and multi-cpu systems
649        - maximum voices and disk streams can now be altered at runtime
650        - fixed CPU feature detection on x86_64 (maybe fixes #108)
651        - automatic stacktrace mechanism is now turned off by default and can
652          be switched on by command line option "--stacktrace" (the automatic
653          stacktrace mechanism seems to be broken on most systems at the moment)
654        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
655          a pointer to the launched InstrumentEditor object
656        - added optional 3rd party user data parameter for following
657          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
658          InstrumentEditor::Launch(),
659          InstrumentManager::LaunchInstrumentEditor()
660        - theoretical fix: made SynchronizedConfig follow C++0x memory
661          model more strictly
662        - fixes for using large audio device buffers
663        - Windows: add the installation directory to the DLL search path
664          when loading an editor plugin (solves problems with VST and
665          gigedit on systems with other GTK versions installed)
666        - updated linuxsampler man page
667    
668      * audio driver:
669        - removed the nonsense audio channel constraint (which was hard coded to
670          max. 100 audio channels) for most audio drivers
671        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
672          opposed to the LSCP specs
673        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
674          reflected the wrong value
675        - fixed a memory management bug in ASIO driver
676        - Makefile fix: JACK_CFLAGS wasn't used
677        - JACK: use jack_client_open instead of the deprecated
678          jack_client_new
679        - added (experimental) CoreAudio driver
680        - applied old fixes to the ASIO driver that were included in the
681          previous binary release but accidentally never committed to CVS
682          (fixes #117)
683        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
684          win64)
685        - VST: added support for sample rate and buffer size changes
686        - VST: close editor (Fantasia) when the VST is removed
687        - VST: avoid opening Fantasia more than once for each VST instance
688        - VST: export main function as "main" on Linux too (fix for
689          energyXT)
690        - VST: changed number of output channels from one stereo to 16
691          stereo
692        - added channel routing, fxsends and midi maps to the settings
693          stored in the plugin state
694        - performance optimization of AudioChannel::MixTo() and
695          AudioChannel::CopyTo() methods using GCC vector exensions
696          (if available)
697        - ASIO fixes: avoid initializing the device twice, avoid throwing
698          exception when getting parameters from a disconnected device
699    
700      * MIDI driver:
701        - added JACK MIDI driver
702        - dispatch bank select as ordinary CC as well, the user might seriously
703          want to (mis)use it for some purpose ("fixed" in all current MIDI
704          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
705        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
706          CoreMidi or AU
707        - fixed mingw-w64 compilation error in MME driver
708        - made program change handling in MIDI thread real-time safe by
709          moving the logic to a non-RT thread
710        - fixed minor memory leak in ALSA driver
711    
712      * instruments database:
713        - avoid time consuming samples scanning when adding instruments
714          to the instruments database
715        - added support for handling lost files in the instruments database
716        - Implemented option for adding instruments in separate directories
717          in the instruments database
718          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
719        - work-around for missing fnmatch function on Windows to make
720          instrument database compilable
721        - added instrument database support on Windows
722          works with both standalone mode and VST plugin.
723          the instruments DB file is located in
724          %USERPROFILE%\.linuxsampler\instruments.db which allows different
725          databases for each windows user
726          if no DB is present it automatically creates the .linuxsampler subdir
727          and then creates an empty DB
728        - fixed recursive import, which was broken on Windows
729    
730      * Gigasampler format engine:
731        - fixed a memory leak that could happen when a channel was deleted
732          while notes were playing
733        - made it possible to load an instrument even if the audio thread
734          isn't running
735        - added partial support for the "Controller Triggered" MIDI rule,
736          enough for piano gigs with pedal noise samples
737        - minor fix: only mark FX sends as being modified if really the
738          respective FX send MIDI controller was used
739        - added support for GM global device volume SysEx message
740          (can be selected at compile time to either apply globally to the
741          whole sampler [default] or only to the sampler channels that are
742          connected to the respective MIDI input port the SysEx message arrived
743          on)
744        - bugfix: notes triggered at position 0 in the audio buffer were
745          sometimes wrongly killed in the same buffer, causing no sound to
746          be played
747        - added support for chromatic / drumkit mode Roland GS Sysex message
748          which is usally used to switch a part between chromatic sounds and
749          drumkit sounds (as opposed to their common default setting of MIDI
750          part 10 being a drumkit part and all other ones chromatic parts), in
751          LS however one can switch between the first 16 MIDI instrument maps
752          defined for the sampler
753        - made it possible to create multiple sample channels even if the
754          audio thread isn't running
755        - fixed crash when removing channel with active voices (#116)
756        - bugfix: on sample reference changes (instrument editor), only
757          un-cache the respective sample if it's really not used by any
758          sampler engine anymore
759        - re-cache samples in case they were changed by an instrument editor,
760          e.g. when a sample was added while playing (#82)
761        - fixed hanging notes which occured when note-off event had the exact
762          same time stamp as the voice's note-on event and occured both in the
763          same audio fragment cycle (fixes bug #112)
764        - added support for the "fine tune" and "pitch bend range"
765          instrument-level gig parameters
766        - fixed minor artifacts in pitch bend handling
767        - added support for GS Reset SysEx message
768        - allow gig files to use unlimited downward pitch shifting
769        - added a limit check for upward pitch shifting
770        - bugfix: sometimes, when playing a note twice fast, the second
771          note was silent
772        - fixed crash happening when a pitch bend event arrived at the
773          same time a new instrument was loading
774    
775      * LSCP server:
776        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
777          react on MIDI data arriving on certain sampler channels (so far only
778          Note-On and Note-Off events are sent via this LSCP event)
779        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
780          react on MIDI data arriving on certain MIDI input devices (so far only
781          Note-On and Note-Off events are sent via this LSCP event)
782        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
783          SET DB_INSTRUMENT FILE_PATH
784        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
785          frontends to send MIDI messages to specific sampler channel
786        - added two additional fields to GET FILE INSTRUMENT INFO command -
787          KEY_BINDINGS and KEYSWITCH_BINDINGS
788        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
789          was incorrect
790        - Optimized the retrieval of the MIDI instrument mappings
791        - added new LSCP command "SET VOICES" to globally alter the maximum
792          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
793          be triggered respectively
794        - added new LSCP command "SET STREAMS" to globally alter the maximum
795          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
796          which will be triggered respectively
797        - bugfix: retry if "select" returns EINTR (this fixes a crash when
798          a gigedit file dialog is opened)
799        - close all connections when LSCPServer is deleted
800        - hard close of all sockets on exit
801        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
802          driver
803    
804      * Bug fixes:
805        - fixed a crash which occurs when removing a sampler channel waiting
806          to start instrument loading after another channel
807        - fixed a crash which occurs when removing a sampler channel with
808          instrument loading in progress (bug #113)
809        - fixed termination caused by uncaught exception when adding MIDI
810          instrument with PERSISTENT load mode
811        - fixed possible iterator invalidations when resetting the sampler
812        - fixed memory leaks when issuing the following LSCP commands:
813          GET AUDIO_OUTPUT_DRIVER INFO
814          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
815          GET MIDI_INPUT_DRIVER INFO
816          GET MIDI_INPUT_DRIVER_PARAMETER INFO
817        - fixed possible compilation error when sqlite is not present
818        - fixed orphaned pointers when setting maximum voices limit (bug #118)
819        - fixed crash when changing the audio output device of a sampler
820          channel with loaded instrument and start playing notes
821        - fixed endless loop in Engine::SuspendAll() (bug #120)
822        - fixed a low-level atomic load function that was broken on 64-bit
823          PowerPC, which probably could cause crashes on that platform
824        - fixed a memory management error which could cause a crash when a
825          plugin was unloaded
826        - bugfix: two private structs had the same name, which could cause
827          problems if the linker chose the wrong constructor
828        - fixed low-level ConditionServer usage bug that caused lockups on
829          Windows
830    
831    
832    Version 0.5.1 (6 December 2007)
833    
834      * packaging changes:
835        - added autoconf checks for pthread library
836        - added autoconf check for pthread bug found on certain NPTL-enabled
837          glibc versions (see Gentoo bug report #194076)
838        - added autoconf checks for MS Windows
839    
840      * general changes:
841        - bugfix: the thread used by an editor plugin didn't die when the
842          editor closed
843        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
844          out all the space. operator--() did not apply size_mask after
845          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
846          order to avoid problems with the _NonVolatileReader functions.
847        - bugfix: Stream.h: added a missing divide by BytesPerSample in
848          GetWriteSpace(). Since this function is currently only used in
849          the stream's qsort() compare function, it didn't trigger any
850          bugs.
851        - Resampler.h, Synthesizer.h: cubic interpolation now works in
852          24bit mode too. Faster method to read 24bit words on little
853          endian machines (x86): replaced 3 byte reads + shifts with a 1
854          unaligned 32bit read and shift
855        - experimental support for MS Windows (MIDI input via MME, AUDIO
856          output via ASIO)
857        - made handling of SIGINT signal (Ctrl-C) a bit more robust
858        - support for monitoring the total number of active disk streams
859          (new LSCP commands: GET TOTAL_STREAM_COUNT,
860          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
861    
862      * AUDIO driver:
863        - added Windows ASIO low latency audio driver
864    
865      * MIDI driver:
866        - added MME Windows MIDI driver
867    
868      * LSCP server:
869        - added support for Windows style path / filenames, however with
870          forward slash path separators instead of backslash
871          (i.e. "C:/foo/bar.gig")
872        - allow naughty liblscp to send non-string device parameters within
873          apostrophes as well
874        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
875          "LIST FILE INSTRUMENTS <file>" and
876          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
877          about an arbitrary instrument file on the system where the sampler is
878          running on
879    
880    Version 0.5.0 (15 October 2007)
881    
882    * packaging changes:    * packaging changes:
883        - config.h is not going to be installed along with liblinuxsampler's
884          API header files anymore
885        - only the API relevant header (and source) files will be exported to
886          the Doxygen API documentation (explicitly listed in Doxyfile.in)
887        - added completely new XCode project files for Mac OSX which is now
888          capable to execute our autoconf environment, thus no need anymore
889          to maintain the compile time configuration file (osx/version.h) for
890          OSX manually (patch by Toshi Nagata)
891        - fixed buggy boolean --enable-foo / --disable-foo configure script
892          parameters
893        - global.h now only covers global definitions that are needed for the
894          C++ API header files, all implementation internal global definitions
895          are now in global_private.h
896        - atomic.h is not exposed to the C++ API anymore
897        - no need to include config.h anymore for using LS's API header files
898        - fixed warnings in API doc generation
899    
900      * general changes:
901        - replaced the old, confusing MIDI program change mechanism by a
902          flexible MIDI instrument mapper which allows to map arbitrary
903          (MIDI bank, MIDI program) pairs with arbitrary
904          (engine type, instrument file, file index) triplets which will be
905          loaded on the respective channel when such MIDI program change
906          messages arrive, beside that, each entry allows to define a life-time
907          strategy for the instrument, so the user can define whether the
908          instrument should i.e. be permanently loaded (to be able to switch
909          quickly among sounds) or i.e. loaded just on demand when the
910          respective program change arrives (to safe RAM space), as well as a
911          global volume factor for each entry, so the user can adjust the volume
912          dynamic of his mapped instrument collection without having to modify
913          the instrument files, also one can manage arbitrary amount of such
914          MIDI instrument maps and assign each sampler channel individually
915          a certain map, so that i.e. separation of normal instruments and
916          drumkits is possible
917        - new notification events for tracking changes to audio/MIDI devices,
918          MIDI instrument maps, MIDI instruments, FX sends, global volume.
919        - sampler was limited to load max. 200 instruments in the background
920          due to a constant size RingBuffer FIFO which is now replaced by a
921          dynamic (unlimited) size std::list FIFO
922        - added FX sends, these allow to route audio signals to arbitrary audio
923          output channels for being processed by external effect processors
924          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
925          controllers
926        - global (sampler wide) volume can now be controlled at runtime
927        - Implemented new, improved notification system
928        - fixed compilation errors regarding OSX
929          (patch by Toshi Nagata)
930        - implemented instruments database
931        - added support for escape sequences to the instruments database
932        - added highly experimental support for on-the-fly instrument editing
933          within the sampler's process (by using instrument editor plugins),
934          you'll notice the new "Registered instrument editors:" message on
935          startup, added a new LSCP command:
936          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
937          to spawn a matching instrument editor for the instrument on the
938          given sampler channel, the plugin path can be overridden at compile
939          time with ./configure --enable-plugin-dir=/some/dir
940        - added experimental code for synchronizing instrument editors hosted
941          in the sampler's process to safely edit instruments while playing
942          without a crash (hopefully) by either suspending single regions
943          wherever possible or if unavoidable whole engine(s)
944        - fixed several issues in fundamental "Thread" class: set scheduling
945          policy and priority on thread level, set a minimum stack size for
946          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
947          threads simply inherited properties of starting thread instead of
948          setting their own policy and priority
949        - minor fix in our automatic stack trace mechanism on crashes, the
950          main process did not wait for the stack trace process to finish
951          its output
952        - fixed some minor memory leaks
953        - reenabled assembly features support, at the moment only for
954          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
955        - minor assembly fix in x86 features detection (don't use the PIC
956          register, to avoid relocations in the text segment at runtime)
957        - POSIX callback functions of Thread.h are hidden
958    
959      * MIDI driver:
960        - dispatch bank select (MSB and LSB) messages
961    
962      * audio driver:
963        - the ALSA audio output driver parameters now reflect the correct
964          parameter value ranges for the respective selected sound card
965          (patch by Till Wimmer, a bit fixed and extended)
966    
967      * Gigasampler format engine:
968        - if a filter is used and EG2 finishes before EG1, let the voice
969          die when EG2 has finished (this fixes a problem with clicks and
970          voice starvation for some gigs)
971        - playback is no longer disabled during instrument loading
972        - all notes playing on a channel that changes its instrument keep
973          playing with the old instrument until they get a note off
974          command
975        - EG fix: a release value of zero could cause noises or crash
976        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
977        - EG fine tuning: when attack is zero the EG starts at a level
978          above max sustain level, which means that there is a decay phase
979          even if sustain is 100%
980        - more EG fixes: the level could sometimes go below zero and cause
981          noises or crashes
982        - minor fix of EGDecay (patch by Toshi Nagata)
983        - fixed compiler error when --enable-override-filter-type was
984          supplied to the configure script (fixes #46)
985        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
986          instead of a fix value
987        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
988          127 (solo mode) only kill voices if the respective mode really
989          changed
990    
991      * LSCP server:
992        - fixed compile time error for old Bison versions
993          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
994        - parser now supports extended ASCII character set
995          (up to ASCII code 255, i.e. includes now umlauts and accents)
996        - filename arguments in LSCP commands now allow to use escape
997          sequences, that is directly literal as one of: \', \", \\, \n, \r,
998          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
999          code value like \xf2) (fixes bug #24)
1000        - the following LSCP commands now also support escape sequences for at
1001          least one of their text-based parameters (i.e. name, description):
1002          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1003          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1004          "SET DB_INSTRUMENT_DIRECTORY NAME",
1005          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1006          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1007          "FIND DB_INSTRUMENT_DIRECTORIES"
1008        - returns verbose syntax errors (line and column where syntax error
1009          occured, the unexpected character and the actually expected, possible
1010          character(s), the latter only if less than 5 possibilities)
1011        - made sure that LSCP syntax is not affected by gigedit locale
1012          settings
1013        - bugfix regarding strings parameter lists: all comma separated lists
1014          of strings were treated as being one string containing commas
1015          (fixes #57)
1016    
1017      * Bug fixes:
1018        - fixed crash occurring on certain LSCP scripts (Bug 39)
1019        - another thread safety fix for lscp "load engine" and "set
1020          channel audio output device"
1021        - fixed a crash which occurs when reassigning the same engine
1022          on a sampler channel with connected MIDI device
1023        - fixed a crash which occurs when changing the number of ports of a MIDI
1024          device connected to a sampler channel to number less then or equal
1025          to the index of the port to which the sampler channel is connected.
1026        - The previous bindings were not been disconnected when altering
1027          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1028          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1029        - The active stream/voice count statistic was incorrect.
1030        - notification events were not been sent for some sampler
1031          channel changes
1032        - added default min and max values to restrict the number of allowed
1033          audio output channels and MIDI input ports
1034        - the connection to the PCM interface is now closed when destroying
1035          an audio output device
1036        - files with slash in their path or filename could not be loaded
1037    
1038      * test cases:
1039        - updated and fixed (haven't been touched in a while)
1040    
1041    Version 0.4.0 (24 November 2006)
1042    
1043      * packaging changes:
1044        - changed deprecated copyright attribute to license; added ldconfig
1045          to post-(un)install steps; added devel package for liblinuxsampler;
1046          to linuxsampler.spec (RPM)

1081        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1082          which can be overridden with --enable-global-attenuation
1083        - EG fixes: made the length of "attack hold" stage more
1084          accurate. Release stage can now start before attack stage
1085          ends. Cancel release didn't work when sustain was zero. Attack
1086          time now has a minimal value to prevent clicks.
1087        - fixed pitch changes larger than one octave
1088        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1089        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1090          all modes can be altered via standard GM messages, that is CC5 for
1091          altering portamento time, CC65 for enabling / disabling portamento
1092          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1093        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1094          parameter) and crossfade
1095        - added support for the "attenuation controller threshold" gig
1096          parameter
1097        - added smoothing of volume changes caused by control change
1098          messages
1099        - sample loop parameters are now taken from the DimensionRegion
1100          instead of the wave chunk
1101        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1102          not equal to a power of two
1103        - reimplementation of the filter algorithm. The new filter is more
1104          accurate and supports all gig filter types, including bandreject
1105          and lowpass turbo.
1106        - real support for 24 bit samples - samples are not truncated to
1107          16 bits anymore
1108        - support for aftertouch (channel pressure, not polyphonic
1109          aftertouch)
1110        - LFO1 behaviour fixed (dampening from max volume instead of
1111          amplifying from 0)
1112    
1113    * LSCP server:    * LSCP server:
1114      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
1115        - fixed the notification messages delay due to lack of
1116          network activity (fixes bug #26)
1117        - fixed parser bug which occured on space(s) within device parameters
1118          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1119    
1120      * audio driver:
1121        - added aRts audio output driver (by no means RT safe)
1122    
1123      * MIDI driver:
1124        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1125          messages several times instead of once
1126        - API extension for MIDI drivers which already supply exact time stamps
1127          for events (i.e. for offline rendering based MIDI drivers)
1128        - added checks for bad MIDI data
1129    
1130      * linuxsampler application:
1131        - show available sampler engine types on startup
1132    
1133    * general changes:    * general changes:
1134      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new

1141        - support for sostenuto pedal
1142        - support for monitoring the total number of active voices
1143          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1144          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1145        - fixed some memory management errors
1146        - fixed some concurrency problems that could lead to crashes when
1147          LSCP commands were executed
1148        - fixed crash when instrument loading failed previously on the same
1149          sampler channel (fixes bug #36)
