1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * plugin changes:
4        - LV2 "state" extension support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).
31        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)

49        - implemented the "round robin keyboard" dimension
50        - fixed round robin and random dimensions for cases when number of
51          dimension zones is not a power of two
52        - made round robin use a counter for each region instead of each
53          key
54    
55      * SFZ format engine:
56        - Initial implementation (not usable yet)
57        - added support for v2 multiple stage envelope generators

81        - optimized sample lookup
82        - improved support for exclusive groups (group, off_by and
83          off_mode)

293      * Bug fixes:
294        - Fixed crash which may occur when MIDI key + transpose is out of range
295        - minor valgrind fixes
296        - fixed crash which occurred when changing an already deployed sampler
297          channel to a different engine type
298        - fixed crash when deleting a sampler channel or changing engine
299          type while an instrument load was in progress
300        - bugfix: playing a note while changing the instrument could cause
301          a crash, or give "Handing back unknown region" error messages
302        - bugfix: calling SET VOICES (which Fantasia does on start and
303          refresh) could cause instruments to be unloaded
304        - Mac OS X: fixed name collision of enum in EffectControl and
305          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
306        - Mac OS X: fixed hanging threads
307        - Windows: disabled the previous thread fix on non-Mac systems, as
308          it caused hanging threads on Windows
309        - Fixed possible crashes due to corrupted MIDI/audio device list
310          after MIDI/audio device creation failure
311        - When creating MIDI instrument map entries with "PERSISTENT" type, the
312          instruments were uselessly precached with zero samples, however it still
313          took the full preloading time and on 1st program change the respective
314          instrument was completely reloaded again.
315        - fixed handling of rapid bank select and program change messages
316          sent to the same sampler channel (patch from the Open Octave
317          project, slightly adjusted)
318        - fixed crash when trying to create an effect instance with controls
319          which min and/or max values depend on the sample rate
320        - fixed bug #162
321        - bugfix: LADSPA_PATH was not evaluated correctly when containing
322          multiple paths (#165)

328    
329    Version 1.0.0 (31 July 2009)
330    
331      * packaging changes:
332        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
333          causing e.g. the libgig test to fail when
334          "./configure --disable-jack-driver" was used
335          (patch by Alexis Ballier)
336        - fixed compilation with gcc 4.3
337        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
338        - fixed configure so it detects x86_64 (#107)
339        - fixes for building with newer MinGW versions
340        - fix for building with bison 2.4 (#111)
341        - fixed building with libgig installed in a non-standard directory
342        - minor fix in configure for mmsystem.h detection on MinGW
343        - Windows: look for editor plugins and Fantasia using base
344          directory of liblinuxsampler dll (look in the same directory and one
345          directory above)
346        - configure script fix: removed unconditional use of SSE
347        - fixed building with sqlite installed in a non-standard directory
348        - when cross-compiling, don't try to create instruments.db
349        - fix for new mingw-w64 version, which has usleep
350    
351      * general changes:
352        - bugfix: on some POSIX systems instrument editor plugins refused to
353          load as we used a non-portable Linux specific struct field
354          (fixes bug #70, patch by Ronald Baljeu)
355        - fixed endless loop which occured when loading an instrument editor
356          plugin DLL on Windows systems failed
357        - fixed memory leaks that occurred when liblinuxsampler was unloaded
358        - optimized the SynchronizedConfig class so it doesn't wait
359          unnecessarily long after an update
360        - added support for notifying instrument editors on note-on / note-off
361          events (e.g. to highlight the pressed keys on the virtual keyboard
362          of gigedit)
363        - added support for triggering notes by instrument editors (see above)
364        - be verbose on DLL load errors (on Linux)
365        - fixed di-harmonic triangle LFO implementation (this LFO implementation
366          is only used by very few systems, most pick the int math
367          implementation, which is usually faster)
368        - fixes for audio drivers with varying buffer sizes
369        - experimental support for running LinuxSampler as a DSSI, LV2 and
370          VST plugin
371        - notification events for stream/voice count statistics are now sent
372          only when there are actual changes
373        - added memory ordering constraints to improve stability on
374          multi-core and multi-cpu systems
375        - maximum voices and disk streams can now be altered at runtime
376        - fixed CPU feature detection on x86_64 (maybe fixes #108)
377        - automatic stacktrace mechanism is now turned off by default and can
378          be switched on by command line option "--stacktrace" (the automatic
379          stacktrace mechanism seems to be broken on most systems at the moment)
380        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
381          a pointer to the launched InstrumentEditor object
382        - added optional 3rd party user data parameter for following
383          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
384          InstrumentEditor::Launch(),
385          InstrumentManager::LaunchInstrumentEditor()
386        - theoretical fix: made SynchronizedConfig follow C++0x memory
387          model more strictly
388        - fixes for using large audio device buffers
389        - Windows: add the installation directory to the DLL search path
390          when loading an editor plugin (solves problems with VST and
391          gigedit on systems with other GTK versions installed)
392    
393      * audio driver:
394        - removed the nonsense audio channel constraint (which was hard coded to
395          max. 100 audio channels) for most audio drivers
396        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
397          opposed to the LSCP specs
398        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
399          reflected the wrong value
400        - fixed a memory management bug in ASIO driver
401        - Makefile fix: JACK_CFLAGS wasn't used
402        - JACK: use jack_client_open instead of the deprecated
403          jack_client_new
404        - added (experimental) CoreAudio driver
405        - applied old fixes to the ASIO driver that were included in the
406          previous binary release but accidentally never committed to CVS
407          (fixes #117)
408        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
409          win64)
410        - VST: added support for sample rate and buffer size changes
411        - VST: close editor (Fantasia) when the VST is removed
412        - VST: avoid opening Fantasia more than once for each VST instance
413        - VST: export main function as "main" on Linux too (fix for
414          energyXT)
415        - VST: changed number of output channels from one stereo to 16
416          stereo
417        - added channel routing, fxsends and midi maps to the settings
418          stored in the plugin state
419        - performance optimization of AudioChannel::MixTo() and
420          AudioChannel::CopyTo() methods using GCC vector exensions
421          (if available)
422        - ASIO fixes: avoid initializing the device twice, avoid throwing
423          exception when getting parameters from a disconnected device
424    
425      * MIDI driver:
426        - added JACK MIDI driver
427        - dispatch bank select as ordinary CC as well, the user might seriously
428          want to (mis)use it for some purpose ("fixed" in all current MIDI
429          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
430        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
431          CoreMidi or AU
432        - fixed mingw-w64 compilation error in MME driver
433        - made program change handling in MIDI thread real-time safe by
434          moving the logic to a non-RT thread
435        - fixed minor memory leak in ALSA driver
436    
437      * instruments database:
438        - avoid time consuming samples scanning when adding instruments
439          to the instruments database
440        - added support for handling lost files in the instruments database
441        - Implemented option for adding instruments in separate directories
442          in the instruments database
443          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
444        - work-around for missing fnmatch function on Windows to make
445          instrument database compilable
446        - added instrument database support on Windows
447          works with both standalone mode and VST plugin.
448          the instruments DB file is located in
449          %USERPROFILE%\.linuxsampler\instruments.db which allows different
450          databases for each windows user
451          if no DB is present it automatically creates the .linuxsampler subdir
452          and then creates an empty DB
453        - fixed recursive import, which was broken on Windows
454    
455      * Gigasampler format engine:
456        - fixed a memory leak that could happen when a channel was deleted
457          while notes were playing
458        - made it possible to load an instrument even if the audio thread
459          isn't running
460        - added partial support for the "Controller Triggered" MIDI rule,
461          enough for piano gigs with pedal noise samples
462        - minor fix: only mark FX sends as being modified if really the
463          respective FX send MIDI controller was used
464        - added support for GM global device volume SysEx message
465          (can be selected at compile time to either apply globally to the
466          whole sampler [default] or only to the sampler channels that are
467          connected to the respective MIDI input port the SysEx message arrived
468          on)
469        - bugfix: notes triggered at position 0 in the audio buffer were
470          sometimes wrongly killed in the same buffer, causing no sound to
471          be played
472        - added support for chromatic / drumkit mode Roland GS Sysex message
473          which is usally used to switch a part between chromatic sounds and
474          drumkit sounds (as opposed to their common default setting of MIDI
475          part 10 being a drumkit part and all other ones chromatic parts), in
476          LS however one can switch between the first 16 MIDI instrument maps
477          defined for the sampler
478        - made it possible to create multiple sample channels even if the
479          audio thread isn't running
480        - fixed crash when removing channel with active voices (#116)
481        - bugfix: on sample reference changes (instrument editor), only
482          un-cache the respective sample if it's really not used by any
483          sampler engine anymore
484        - re-cache samples in case they were changed by an instrument editor,
485          e.g. when a sample was added while playing (#82)
486        - fixed hanging notes which occured when note-off event had the exact
487          same time stamp as the voice's note-on event and occured both in the
488          same audio fragment cycle (fixes bug #112)
489        - added support for the "fine tune" and "pitch bend range"
490          instrument-level gig parameters
491        - fixed minor artifacts in pitch bend handling
492        - added support for GS Reset SysEx message
493        - allow gig files to use unlimited downward pitch shifting
494        - added a limit check for upward pitch shifting
495        - bugfix: sometimes, when playing a note twice fast, the second
496          note was silent
497        - fixed crash happening when a pitch bend event arrived at the
498          same time a new instrument was loading
499    
500      * LSCP server:
501        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
502          react on MIDI data arriving on certain sampler channels (so far only
503          Note-On and Note-Off events are sent via this LSCP event)
504        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
505          react on MIDI data arriving on certain MIDI input devices (so far only
506          Note-On and Note-Off events are sent via this LSCP event)
507        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
508          SET DB_INSTRUMENT FILE_PATH
509        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
510          frontends to send MIDI messages to specific sampler channel
511        - added two additional fields to GET FILE INSTRUMENT INFO command -
512          KEY_BINDINGS and KEYSWITCH_BINDINGS
513        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
514          was incorrect
515        - Optimized the retrieval of the MIDI instrument mappings
516        - added new LSCP command "SET VOICES" to globally alter the maximum
517          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
518          be triggered respectively
519        - added new LSCP command "SET STREAMS" to globally alter the maximum
520          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
521          which will be triggered respectively
522        - bugfix: retry if "select" returns EINTR (this fixes a crash when
523          a gigedit file dialog is opened)
524        - close all connections when LSCPServer is deleted
525        - hard close of all sockets on exit
526        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
527          driver
528    
529      * Bug fixes:
530        - fixed a crash which occurs when removing a sampler channel waiting
531          to start instrument loading after another channel
532        - fixed a crash which occurs when removing a sampler channel with
533          instrument loading in progress (bug #113)
534        - fixed termination caused by uncaught exception when adding MIDI
535          instrument with PERSISTENT load mode
536        - fixed possible iterator invalidations when resetting the sampler
537        - fixed memory leaks when issuing the following LSCP commands:
538          GET AUDIO_OUTPUT_DRIVER INFO
539          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
540          GET MIDI_INPUT_DRIVER INFO
541          GET MIDI_INPUT_DRIVER_PARAMETER INFO
542        - fixed possible compilation error when sqlite is not present
543        - fixed orphaned pointers when setting maximum voices limit (bug #118)
544        - fixed crash when changing the audio output device of a sampler
545          channel with loaded instrument and start playing notes
546        - fixed endless loop in Engine::SuspendAll() (bug #120)
547        - fixed a low-level atomic load function that was broken on 64-bit
548          PowerPC, which probably could cause crashes on that platform
549        - fixed a memory management error which could cause a crash when a
550          plugin was unloaded
551        - bugfix: two private structs had the same name, which could cause
552          problems if the linker chose the wrong constructor
553        - fixed low-level ConditionServer usage bug that caused lockups on
554          Windows
555    
556    
557    Version 0.5.1 (6 December 2007)
558    
559      * packaging changes:
560        - added autoconf checks for pthread library
561        - added autoconf check for pthread bug found on certain NPTL-enabled
562          glibc versions (see Gentoo bug report #194076)
563        - added autoconf checks for MS Windows
564    
565      * general changes:
566        - bugfix: the thread used by an editor plugin didn't die when the
567          editor closed
568        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
569          out all the space. operator--() did not apply size_mask after
570          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
571          order to avoid problems with the _NonVolatileReader functions.
572        - bugfix: Stream.h: added a missing divide by BytesPerSample in
573          GetWriteSpace(). Since this function is currently only used in
574          the stream's qsort() compare function, it didn't trigger any
575          bugs.
576        - Resampler.h, Synthesizer.h: cubic interpolation now works in
577          24bit mode too. Faster method to read 24bit words on little
578          endian machines (x86): replaced 3 byte reads + shifts with a 1
579          unaligned 32bit read and shift
580        - experimental support for MS Windows (MIDI input via MME, AUDIO
581          output via ASIO)
582        - made handling of SIGINT signal (Ctrl-C) a bit more robust
583        - support for monitoring the total number of active disk streams
584          (new LSCP commands: GET TOTAL_STREAM_COUNT,
585          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
586    
587      * AUDIO driver:
588        - added Windows ASIO low latency audio driver
589    
590      * MIDI driver:
591        - added MME Windows MIDI driver
592    
593      * LSCP server:
594        - added support for Windows style path / filenames, however with
595          forward slash path separators instead of backslash
596          (i.e. "C:/foo/bar.gig")
597        - allow naughty liblscp to send non-string device parameters within
598          apostrophes as well
599        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
600          "LIST FILE INSTRUMENTS <file>" and
601          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
602          about an arbitrary instrument file on the system where the sampler is
603          running on
604    
605    Version 0.5.0 (15 October 2007)
606    
607      * packaging changes:
608        - config.h is not going to be installed along with liblinuxsampler's
609          API header files anymore
610        - only the API relevant header (and source) files will be exported to
611          the Doxygen API documentation (explicitly listed in Doxyfile.in)
612        - added completely new XCode project files for Mac OSX which is now
613          capable to execute our autoconf environment, thus no need anymore
614          to maintain the compile time configuration file (osx/version.h) for
615          OSX manually (patch by Toshi Nagata)
616        - fixed buggy boolean --enable-foo / --disable-foo configure script
617          parameters
618        - global.h now only covers global definitions that are needed for the
619          C++ API header files, all implementation internal global definitions
620          are now in global_private.h
621        - atomic.h is not exposed to the C++ API anymore
622        - no need to include config.h anymore for using LS's API header files
623        - fixed warnings in API doc generation
624    
625    * general changes:    * general changes:
626      - replaced the old, confusing MIDI program change mechanism by a      - replaced the old, confusing MIDI program change mechanism by a

647        - added FX sends, these allow to route audio signals to arbitrary audio
648          output channels for being processed by external effect processors
649          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
650          controllers
651        - global (sampler wide) volume can now be controlled at runtime
652        - Implemented new, improved notification system
653        - fixed compilation errors regarding OSX
654          (patch by Toshi Nagata)
655        - implemented instruments database
656        - added support for escape sequences to the instruments database
657        - added highly experimental support for on-the-fly instrument editing
658          within the sampler's process (by using instrument editor plugins),
659          you'll notice the new "Registered instrument editors:" message on
660          startup, added a new LSCP command:
661          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
662          to spawn a matching instrument editor for the instrument on the
663          given sampler channel, the plugin path can be overridden at compile
664          time with ./configure --enable-plugin-dir=/some/dir
665        - added experimental code for synchronizing instrument editors hosted
666          in the sampler's process to safely edit instruments while playing
667          without a crash (hopefully) by either suspending single regions
668          wherever possible or if unavoidable whole engine(s)
669        - fixed several issues in fundamental "Thread" class: set scheduling
670          policy and priority on thread level, set a minimum stack size for
671          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
672          threads simply inherited properties of starting thread instead of
673          setting their own policy and priority
674        - minor fix in our automatic stack trace mechanism on crashes, the
675          main process did not wait for the stack trace process to finish
676          its output
677        - fixed some minor memory leaks
678        - reenabled assembly features support, at the moment only for
679          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
680        - minor assembly fix in x86 features detection (don't use the PIC
681          register, to avoid relocations in the text segment at runtime)
682        - POSIX callback functions of Thread.h are hidden
683    
684    * MIDI driver:    * MIDI driver:
685      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages
686    
687      * audio driver:
688        - the ALSA audio output driver parameters now reflect the correct
689          parameter value ranges for the respective selected sound card
690          (patch by Till Wimmer, a bit fixed and extended)
691    
692    * Gigasampler format engine:    * Gigasampler format engine:
693      - if a filter is used and EG2 finishes before EG1, let the voice      - if a filter is used and EG2 finishes before EG1, let the voice
694        die when EG2 has finished (this fixes a problem with clicks and        die when EG2 has finished (this fixes a problem with clicks and
695        voice starvation for some gigs)        voice starvation for some gigs)
696        - playback is no longer disabled during instrument loading
697        - all notes playing on a channel that changes its instrument keep
698          playing with the old instrument until they get a note off
699          command
700        - EG fix: a release value of zero could cause noises or crash
701        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
702        - EG fine tuning: when attack is zero the EG starts at a level
703          above max sustain level, which means that there is a decay phase
704          even if sustain is 100%
705        - more EG fixes: the level could sometimes go below zero and cause
706          noises or crashes
707        - minor fix of EGDecay (patch by Toshi Nagata)
708        - fixed compiler error when --enable-override-filter-type was
709          supplied to the configure script (fixes #46)
710        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
711          instead of a fix value
712        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
713          127 (solo mode) only kill voices if the respective mode really
714          changed
715    
716      * LSCP server:
717        - fixed compile time error for old Bison versions
718          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
719        - parser now supports extended ASCII character set
720          (up to ASCII code 255, i.e. includes now umlauts and accents)
721        - filename arguments in LSCP commands now allow to use escape
722          sequences, that is directly literal as one of: \', \", \\, \n, \r,
723          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
724          code value like \xf2) (fixes bug #24)
725        - the following LSCP commands now also support escape sequences for at
726          least one of their text-based parameters (i.e. name, description):
727          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
