9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X

18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with

29        - build fix: libsndfile compiler flags were missing in some
30          makefiles
31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37    
38      * general changes:
39        - Refactoring: moved the independent code from
40          the Gigasampler format engine to base classes
41        - command line option '--profile' is currently disabled, since the
42          respective profiling code is currently broken
43        - Introduced support for optional environment variable
44          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45          where the sampler shall look for instrument editor plugins
46          (patch by Luis Garrido, slightly modified).
47        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50          note (in this implementation of the sampler its simply hard routed to
51          the 1st effect send of the sampler channel, no matter what the actual
52          effect type is)
53        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54          note (in this implementation of the sampler its simply hard routed to
55          the 2nd effect send of the sampler channel, no matter what the actual
56          effect type is)
57        - implemented support for internal LADSPA effects
58        - raised limit of program change queue from 100 to 512
59          (as suggested by Alex Stone)
60        - implemented sine LFO, pulse LFO and saw LFO
61        - experimental support for per voice equalization
62        - added command line option --exec-after-init
63        - Introduced new C++ API method:
64          EngineChannel::InstrumentFileName(int index)
65          allowing to retrieve the whole list of files used for the loaded
66          instrument on an engine channel (a.k.a. part). Some GigaStudio
67          instruments for example are splitted over several files like
68          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69        - Added new C++ API method Sampler::GetGlobalMaxVoices().
70        - Added new C++ API method Sampler::GetGlobalMaxStreams().
71        - Added new C++ API method Sampler::SetGlobalMaxVoices().
72        - Added new C++ API method Sampler::SetGlobalMaxStreams().
73        - Various "const" and "restrict" optimizations.
74        - all engines: add pan CC value to instrument pan parameter before
75          applying panning, instead of using two separate pan functions in
76          series (#182)
77        - added a lock guard class for exception safe mutex handling and
78          used it everywhere appropriate
79        - Immediately apply scale tuning changes to active voices.
80        - Exposed scale tuning to C++ API (along to the already existing standard
81          SysEx way).
82        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83          and broken for ppc64. (Seq_cst loads and stores are actually not
84          used in LS, so the bug wasn't noticable.)
85        - lsatomic.h: added ARMv7 support
86        - Added support for multiple MIDI input ports per sampler channel (and
87          added various new C++ methods for this new feature / design change, old
88          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89          as deprecated but are still there and should provide full behavior
90          backward compatibility).
91        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92          unsafe and caused compilation error with clang 2.x).
93        - Bugfix: only process the latest MIDI program change event.
94    
95      * Gigasampler format engine:
96        - implemented the "round robin keyboard" dimension
97        - fixed round robin and random dimensions for cases when number of
98          dimension zones is not a power of two
99        - made round robin use a counter for each region instead of each
100          key
101        - bugfix: pitch LFO controller "internal+aftertouch" was broken
102        - bugfix: filter keyboard tracking was broken
103        - filter performance fix (an unnecessary copy was made of the
104          filter parameters in each sub fragment)
105        - handle special case when pan parameter in gig file has max or
106          min value
107        - Exclusive Groups: don't ever stop voices of the same note,
108          doesn't sound naturally with a drumkit
109        - fixed EG1 modulation when attack or release is zero
110    
111      * SFZ format engine:
112        - Initial implementation (not usable yet)
113        - added support for v2 multiple stage envelope generators
114        - added a fine-tuned v1 envelope generator instead of using the
115          one from the gig engine
116        - fixed memory leak and memory handling errors
117        - added support for trigger=first, trigger=legato and sw_previous
118        - allow non-numerical key values ("C#4" for example)
119        - "key" opcode now sets pitch_keycenter too
120        - fixed error when unloading instrument with same sample used by
121          multiple regions

281        - Listen to all interfaces on Mac OS X (INADDR_ANY)
282        - VST bugfix: If the host called resume() before and after
283          changing sample rate or block size, the number of channels was
284          incorrectly set to two. This caused silence in Cubase 5.
285        - save engine type (gig, sfz or sf2) in plugin state
286        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
287          64 bit Windows
288        - AU: changed number of output channels from one stereo to 16
289          stereo
290        - VST: made it possible to build the VST plugin for Mac
291        - AU: link AU plugin dynamically if --disable-shared isn't
292          specified
293        - LV2 "state" extension support (patch by David Robillard)

295          the plugin was loaded a second time (#174)
296        - plugin bugfix: instrument loading hang when the plugin was
297          loaded a second time (this time it's for Linux and Mac, previous
298          similar fix was for Windows)
299        - thread safety fixes for the instrument loading thread
300        - LV2: use the new lv2 package if present
301        - VST: try to open Fantasia automatically on Linux and Mac too (on
302          Linux, the Fantasia jar should be placed in <prefix>/share/java)
303        - VST: fixed crashes on Linux Ardour and EnergyXT
304        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
305          port and audio channel routing for DSSI plugins are now visible.
306        - LV2: use urid and atom extensions instead of deprecated uri-map
307          and event
308        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
309        - LV2: changed number of output channels to 16 stereo, just like
310          the VST and AU plugins
311        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
312        - LV2: made LV2 plugin buildable on Windows and Mac
313        - VST: implemented retrieval and switching of programs using the
314          sampler's internal MIDI instrument mapping system
315    
316      * MIDI driver:
317        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
318          the ALSA sequencer client name
319        - removed limit of maximum amount of MIDI ports per MIDI device, since
320          there is no reason for this limit
321        - MME: fixed memory handling bug found with cppcheck
322        - MME: removed compiler warning
323        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
324          which allows to retrieve the list of CoreMIDI clients / ports and to connect
325          to them a la JACK, via the usual sampler APIs
326        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
327          the driver will automatically connect to other CoreMIDI clients' ports
328          (e.g. external MIDI devices being attached to the Mac)
329        - added support for MIDI note on velocity filter
330        - CoreMIDI: fixed memory deallocation error

344        - ASIO driver: removed compiler warnings
345        - CoreAudio: fixed minor error handling bug
346        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

394        - fixed crash when deleting a sampler channel or changing engine
395          type while an instrument load was in progress
396        - bugfix: playing a note while changing the instrument could cause
397          a crash, or give "Handing back unknown region" error messages
398        - bugfix: calling SET VOICES (which Fantasia does on start and
399          refresh) could cause instruments to be unloaded
400        - Mac OS X: fixed name collision of enum in EffectControl and
401          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
402        - Mac OS X: fixed hanging threads
403        - Windows: disabled the previous thread fix on non-Mac systems, as
404          it caused hanging threads on Windows
405        - Fixed possible crashes due to corrupted MIDI/audio device list
406          after MIDI/audio device creation failure
407        - When creating MIDI instrument map entries with "PERSISTENT" type, the
408          instruments were uselessly precached with zero samples, however it still
409          took the full preloading time and on 1st program change the respective
410          instrument was completely reloaded again.
411        - fixed handling of rapid bank select and program change messages
412          sent to the same sampler channel (patch from the Open Octave
413          project, slightly adjusted)
414        - fixed crash when trying to create an effect instance with controls
415          which min and/or max values depend on the sample rate

428          playing a note in a key group
429        - fixed erroneous error message piping in VoiceBase.h
430          (labelled "Disk stream not available in time")
431        - Update effects on sample rate & period size changes (to avoid
432          crashes and noise on such transitions).
433        - ignore missing LADSPA paths without ignoring valid LADSPA paths
434          (fixes #208)
435    
436    Version 1.0.0 (31 July 2009)
437    
438      * packaging changes:
439        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
440          causing e.g. the libgig test to fail when
441          "./configure --disable-jack-driver" was used
442          (patch by Alexis Ballier)
443        - fixed compilation with gcc 4.3

448        - fixed building with libgig installed in a non-standard directory
449        - minor fix in configure for mmsystem.h detection on MinGW
450        - Windows: look for editor plugins and Fantasia using base
451          directory of liblinuxsampler dll (look in the same directory and one
452          directory above)
453        - configure script fix: removed unconditional use of SSE
454        - fixed building with sqlite installed in a non-standard directory
455        - when cross-compiling, don't try to create instruments.db
456        - fix for new mingw-w64 version, which has usleep
457    
458      * general changes:
459        - bugfix: on some POSIX systems instrument editor plugins refused to
460          load as we used a non-portable Linux specific struct field
461          (fixes bug #70, patch by Ronald Baljeu)
462        - fixed endless loop which occured when loading an instrument editor
463          plugin DLL on Windows systems failed
464        - fixed memory leaks that occurred when liblinuxsampler was unloaded
465        - optimized the SynchronizedConfig class so it doesn't wait
466          unnecessarily long after an update
467        - added support for notifying instrument editors on note-on / note-off
468          events (e.g. to highlight the pressed keys on the virtual keyboard
469          of gigedit)
470        - added support for triggering notes by instrument editors (see above)
471        - be verbose on DLL load errors (on Linux)
472        - fixed di-harmonic triangle LFO implementation (this LFO implementation
473          is only used by very few systems, most pick the int math
474          implementation, which is usually faster)
475        - fixes for audio drivers with varying buffer sizes
476        - experimental support for running LinuxSampler as a DSSI, LV2 and
477          VST plugin
478        - notification events for stream/voice count statistics are now sent
479          only when there are actual changes
480        - added memory ordering constraints to improve stability on
481          multi-core and multi-cpu systems
482        - maximum voices and disk streams can now be altered at runtime
483        - fixed CPU feature detection on x86_64 (maybe fixes #108)
484        - automatic stacktrace mechanism is now turned off by default and can
485          be switched on by command line option "--stacktrace" (the automatic
486          stacktrace mechanism seems to be broken on most systems at the moment)
487        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
488          a pointer to the launched InstrumentEditor object
489        - added optional 3rd party user data parameter for following
490          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
491          InstrumentEditor::Launch(),
492          InstrumentManager::LaunchInstrumentEditor()
493        - theoretical fix: made SynchronizedConfig follow C++0x memory
494          model more strictly
495        - fixes for using large audio device buffers
496        - Windows: add the installation directory to the DLL search path
497          when loading an editor plugin (solves problems with VST and
498          gigedit on systems with other GTK versions installed)
499        - updated linuxsampler man page
500    
501      * audio driver:
502        - removed the nonsense audio channel constraint (which was hard coded to
503          max. 100 audio channels) for most audio drivers
504        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
505          opposed to the LSCP specs
506        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
507          reflected the wrong value
508        - fixed a memory management bug in ASIO driver
509        - Makefile fix: JACK_CFLAGS wasn't used
510        - JACK: use jack_client_open instead of the deprecated
511          jack_client_new
512        - added (experimental) CoreAudio driver
513        - applied old fixes to the ASIO driver that were included in the
514          previous binary release but accidentally never committed to CVS
515          (fixes #117)
516        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
517          win64)
518        - VST: added support for sample rate and buffer size changes
519        - VST: close editor (Fantasia) when the VST is removed
520        - VST: avoid opening Fantasia more than once for each VST instance
521        - VST: export main function as "main" on Linux too (fix for
522          energyXT)
523        - VST: changed number of output channels from one stereo to 16
524          stereo
525        - added channel routing, fxsends and midi maps to the settings
526          stored in the plugin state
527        - performance optimization of AudioChannel::MixTo() and
528          AudioChannel::CopyTo() methods using GCC vector exensions
529          (if available)
530        - ASIO fixes: avoid initializing the device twice, avoid throwing
531          exception when getting parameters from a disconnected device
532    
533      * MIDI driver:
534        - added JACK MIDI driver
535        - dispatch bank select as ordinary CC as well, the user might seriously
536          want to (mis)use it for some purpose ("fixed" in all current MIDI
537          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
538        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
539          CoreMidi or AU
540        - fixed mingw-w64 compilation error in MME driver
541        - made program change handling in MIDI thread real-time safe by
542          moving the logic to a non-RT thread
543        - fixed minor memory leak in ALSA driver
544    
545      * instruments database:
546        - avoid time consuming samples scanning when adding instruments
547          to the instruments database
548        - added support for handling lost files in the instruments database
549        - Implemented option for adding instruments in separate directories
550          in the instruments database
551          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
552        - work-around for missing fnmatch function on Windows to make
553          instrument database compilable
554        - added instrument database support on Windows
555          works with both standalone mode and VST plugin.
556          the instruments DB file is located in
557          %USERPROFILE%\.linuxsampler\instruments.db which allows different
558          databases for each windows user
559          if no DB is present it automatically creates the .linuxsampler subdir
560          and then creates an empty DB
561        - fixed recursive import, which was broken on Windows
562    
563      * Gigasampler format engine:
564        - fixed a memory leak that could happen when a channel was deleted
565          while notes were playing
566        - made it possible to load an instrument even if the audio thread
567          isn't running
568        - added partial support for the "Controller Triggered" MIDI rule,
569          enough for piano gigs with pedal noise samples
570        - minor fix: only mark FX sends as being modified if really the
571          respective FX send MIDI controller was used
572        - added support for GM global device volume SysEx message
573          (can be selected at compile time to either apply globally to the
574          whole sampler [default] or only to the sampler channels that are
575          connected to the respective MIDI input port the SysEx message arrived
576          on)
577        - bugfix: notes triggered at position 0 in the audio buffer were
578          sometimes wrongly killed in the same buffer, causing no sound to
579          be played
580        - added support for chromatic / drumkit mode Roland GS Sysex message
581          which is usally used to switch a part between chromatic sounds and
582          drumkit sounds (as opposed to their common default setting of MIDI
583          part 10 being a drumkit part and all other ones chromatic parts), in
584          LS however one can switch between the first 16 MIDI instrument maps
585          defined for the sampler
586        - made it possible to create multiple sample channels even if the
587          audio thread isn't running
588        - fixed crash when removing channel with active voices (#116)
589        - bugfix: on sample reference changes (instrument editor), only
590          un-cache the respective sample if it's really not used by any
591          sampler engine anymore
592        - re-cache samples in case they were changed by an instrument editor,
593          e.g. when a sample was added while playing (#82)
594        - fixed hanging notes which occured when note-off event had the exact
595          same time stamp as the voice's note-on event and occured both in the
596          same audio fragment cycle (fixes bug #112)
597        - added support for the "fine tune" and "pitch bend range"
598          instrument-level gig parameters
599        - fixed minor artifacts in pitch bend handling
600        - added support for GS Reset SysEx message
601        - allow gig files to use unlimited downward pitch shifting
602        - added a limit check for upward pitch shifting
603        - bugfix: sometimes, when playing a note twice fast, the second
604          note was silent
605        - fixed crash happening when a pitch bend event arrived at the
606          same time a new instrument was loading
607    
608      * LSCP server:
609        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
610          react on MIDI data arriving on certain sampler channels (so far only
611          Note-On and Note-Off events are sent via this LSCP event)
612        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
613          react on MIDI data arriving on certain MIDI input devices (so far only
614          Note-On and Note-Off events are sent via this LSCP event)
615        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
616          SET DB_INSTRUMENT FILE_PATH
617        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
618          frontends to send MIDI messages to specific sampler channel
619        - added two additional fields to GET FILE INSTRUMENT INFO command -
620          KEY_BINDINGS and KEYSWITCH_BINDINGS
621        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
622          was incorrect
623        - Optimized the retrieval of the MIDI instrument mappings
624        - added new LSCP command "SET VOICES" to globally alter the maximum
625          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
626          be triggered respectively
627        - added new LSCP command "SET STREAMS" to globally alter the maximum
628          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
629          which will be triggered respectively
630        - bugfix: retry if "select" returns EINTR (this fixes a crash when
631          a gigedit file dialog is opened)
632        - close all connections when LSCPServer is deleted
633        - hard close of all sockets on exit
634        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
635          driver
636    
637      * Bug fixes:
638        - fixed a crash which occurs when removing a sampler channel waiting
639          to start instrument loading after another channel
640        - fixed a crash which occurs when removing a sampler channel with
641          instrument loading in progress (bug #113)
642        - fixed termination caused by uncaught exception when adding MIDI
643          instrument with PERSISTENT load mode
644        - fixed possible iterator invalidations when resetting the sampler
645        - fixed memory leaks when issuing the following LSCP commands:
646          GET AUDIO_OUTPUT_DRIVER INFO
647          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
648          GET MIDI_INPUT_DRIVER INFO
649          GET MIDI_INPUT_DRIVER_PARAMETER INFO
650        - fixed possible compilation error when sqlite is not present
651        - fixed orphaned pointers when setting maximum voices limit (bug #118)
652        - fixed crash when changing the audio output device of a sampler
653          channel with loaded instrument and start playing notes
654        - fixed endless loop in Engine::SuspendAll() (bug #120)
655        - fixed a low-level atomic load function that was broken on 64-bit
656          PowerPC, which probably could cause crashes on that platform
657        - fixed a memory management error which could cause a crash when a
658          plugin was unloaded
659        - bugfix: two private structs had the same name, which could cause
660          problems if the linker chose the wrong constructor
661        - fixed low-level ConditionServer usage bug that caused lockups on
662          Windows
663    
664    
665    Version 0.5.1 (6 December 2007)
666    
667      * packaging changes:
668        - added autoconf checks for pthread library
669        - added autoconf check for pthread bug found on certain NPTL-enabled
670          glibc versions (see Gentoo bug report #194076)
671        - added autoconf checks for MS Windows
672    
673      * general changes:
674        - bugfix: the thread used by an editor plugin didn't die when the
675          editor closed
676        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
677          out all the space. operator--() did not apply size_mask after
678          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
679          order to avoid problems with the _NonVolatileReader functions.
680        - bugfix: Stream.h: added a missing divide by BytesPerSample in
681          GetWriteSpace(). Since this function is currently only used in
682          the stream's qsort() compare function, it didn't trigger any
683          bugs.
684        - Resampler.h, Synthesizer.h: cubic interpolation now works in
685          24bit mode too. Faster method to read 24bit words on little
686          endian machines (x86): replaced 3 byte reads + shifts with a 1
687          unaligned 32bit read and shift
688        - experimental support for MS Windows (MIDI input via MME, AUDIO
689          output via ASIO)
690        - made handling of SIGINT signal (Ctrl-C) a bit more robust
691        - support for monitoring the total number of active disk streams
692          (new LSCP commands: GET TOTAL_STREAM_COUNT,
693          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
694    
695      * AUDIO driver:
696        - added Windows ASIO low latency audio driver
697    
698      * MIDI driver:
699        - added MME Windows MIDI driver
700    
701      * LSCP server:
702        - added support for Windows style path / filenames, however with
703          forward slash path separators instead of backslash
704          (i.e. "C:/foo/bar.gig")
705        - allow naughty liblscp to send non-string device parameters within
706          apostrophes as well
707        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
708          "LIST FILE INSTRUMENTS <file>" and
709          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
710          about an arbitrary instrument file on the system where the sampler is
711          running on
712    
713    Version 0.5.0 (15 October 2007)

857          device connected to a sampler channel to number less then or equal
858          to the index of the port to which the sampler channel is connected.
859        - The previous bindings were not been disconnected when altering
860          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
861          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
862        - The active stream/voice count statistic was incorrect.
863        - notification events were not been sent for some sampler
864          channel changes
865        - added default min and max values to restrict the number of allowed
866          audio output channels and MIDI input ports
867        - the connection to the PCM interface is now closed when destroying
868          an audio output device
