3      * plugin changes:
4        - LV2 "state" extension support (patch by David Robillard)
5    
6    * packaging changes:    * 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

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

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

292          channel to a different engine type
293        - fixed crash when deleting a sampler channel or changing engine
294          type while an instrument load was in progress
295        - bugfix: playing a note while changing the instrument could cause
296          a crash, or give "Handing back unknown region" error messages
297        - bugfix: calling SET VOICES (which Fantasia does on start and
298          refresh) could cause instruments to be unloaded

300          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
301        - Mac OS X: fixed hanging threads

303          it caused hanging threads on Windows
304        - Fixed possible crashes due to corrupted MIDI/audio device list
305          after MIDI/audio device creation failure
306        - When creating MIDI instrument map entries with "PERSISTENT" type, the
307          instruments were uselessly precached with zero samples, however it still
308          took the full preloading time and on 1st program change the respective
309          instrument was completely reloaded again.
310        - fixed handling of rapid bank select and program change messages
311          sent to the same sampler channel (patch from the Open Octave
312          project, slightly adjusted)
313        - fixed crash when trying to create an effect instance with controls
314          which min and/or max values depend on the sample rate
315        - fixed bug #162
316        - bugfix: LADSPA_PATH was not evaluated correctly when containing
317          multiple paths (#165)

319    Version 1.0.0 (31 July 2009)
320    
321      * packaging changes:
322        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
323          causing e.g. the libgig test to fail when
324          "./configure --disable-jack-driver" was used
325          (patch by Alexis Ballier)
326        - fixed compilation with gcc 4.3

335          directory above)
336        - configure script fix: removed unconditional use of SSE
337        - fixed building with sqlite installed in a non-standard directory
338        - when cross-compiling, don't try to create instruments.db
339        - fix for new mingw-w64 version, which has usleep
340    
341      * general changes:
342        - bugfix: on some POSIX systems instrument editor plugins refused to
343          load as we used a non-portable Linux specific struct field
344          (fixes bug #70, patch by Ronald Baljeu)
345        - fixed endless loop which occured when loading an instrument editor
346          plugin DLL on Windows systems failed
347        - fixed memory leaks that occurred when liblinuxsampler was unloaded
348        - optimized the SynchronizedConfig class so it doesn't wait
349          unnecessarily long after an update
350        - added support for notifying instrument editors on note-on / note-off
351          events (e.g. to highlight the pressed keys on the virtual keyboard
352          of gigedit)
353        - added support for triggering notes by instrument editors (see above)
354        - be verbose on DLL load errors (on Linux)
355        - fixed di-harmonic triangle LFO implementation (this LFO implementation
356          is only used by very few systems, most pick the int math
357          implementation, which is usually faster)
358        - fixes for audio drivers with varying buffer sizes
359        - experimental support for running LinuxSampler as a DSSI, LV2 and
360          VST plugin
361        - notification events for stream/voice count statistics are now sent
362          only when there are actual changes
363        - added memory ordering constraints to improve stability on
364          multi-core and multi-cpu systems
365        - maximum voices and disk streams can now be altered at runtime
366        - fixed CPU feature detection on x86_64 (maybe fixes #108)
367        - automatic stacktrace mechanism is now turned off by default and can
368          be switched on by command line option "--stacktrace" (the automatic
369          stacktrace mechanism seems to be broken on most systems at the moment)
370        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
371          a pointer to the launched InstrumentEditor object
372        - added optional 3rd party user data parameter for following
373          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
374          InstrumentEditor::Launch(),
375          InstrumentManager::LaunchInstrumentEditor()
376        - theoretical fix: made SynchronizedConfig follow C++0x memory
377          model more strictly
378        - fixes for using large audio device buffers
379        - Windows: add the installation directory to the DLL search path
380          when loading an editor plugin (solves problems with VST and
381          gigedit on systems with other GTK versions installed)
382    
383      * audio driver:
384        - removed the nonsense audio channel constraint (which was hard coded to
385          max. 100 audio channels) for most audio drivers
386        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
387          opposed to the LSCP specs
388        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
389          reflected the wrong value
390        - fixed a memory management bug in ASIO driver
391        - Makefile fix: JACK_CFLAGS wasn't used
392        - JACK: use jack_client_open instead of the deprecated
393          jack_client_new
394        - added (experimental) CoreAudio driver
395        - applied old fixes to the ASIO driver that were included in the
396          previous binary release but accidentally never committed to CVS
397          (fixes #117)
398        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
399          win64)
400        - VST: added support for sample rate and buffer size changes
401        - VST: close editor (Fantasia) when the VST is removed
402        - VST: avoid opening Fantasia more than once for each VST instance
403        - VST: export main function as "main" on Linux too (fix for
404          energyXT)
405        - VST: changed number of output channels from one stereo to 16
406          stereo
407        - added channel routing, fxsends and midi maps to the settings
408          stored in the plugin state
409        - performance optimization of AudioChannel::MixTo() and
410          AudioChannel::CopyTo() methods using GCC vector exensions
411          (if available)
412        - ASIO fixes: avoid initializing the device twice, avoid throwing
413          exception when getting parameters from a disconnected device
414    
415      * MIDI driver:
416        - added JACK MIDI driver
417        - dispatch bank select as ordinary CC as well, the user might seriously
418          want to (mis)use it for some purpose ("fixed" in all current MIDI
419          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
420        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
421          CoreMidi or AU
422        - fixed mingw-w64 compilation error in MME driver
423        - made program change handling in MIDI thread real-time safe by
424          moving the logic to a non-RT thread
425        - fixed minor memory leak in ALSA driver
426    
427      * instruments database:
428        - avoid time consuming samples scanning when adding instruments
429          to the instruments database
430        - added support for handling lost files in the instruments database
431        - Implemented option for adding instruments in separate directories
432          in the instruments database
433          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
434        - work-around for missing fnmatch function on Windows to make
435          instrument database compilable
436        - added instrument database support on Windows
437          works with both standalone mode and VST plugin.
438          the instruments DB file is located in
439          %USERPROFILE%\.linuxsampler\instruments.db which allows different
440          databases for each windows user
441          if no DB is present it automatically creates the .linuxsampler subdir
442          and then creates an empty DB
443        - fixed recursive import, which was broken on Windows
444    
445      * Gigasampler format engine:
446        - fixed a memory leak that could happen when a channel was deleted
447          while notes were playing
448        - made it possible to load an instrument even if the audio thread
449          isn't running
450        - added partial support for the "Controller Triggered" MIDI rule,
451          enough for piano gigs with pedal noise samples
452        - minor fix: only mark FX sends as being modified if really the
453          respective FX send MIDI controller was used
454        - added support for GM global device volume SysEx message
455          (can be selected at compile time to either apply globally to the
456          whole sampler [default] or only to the sampler channels that are
457          connected to the respective MIDI input port the SysEx message arrived
458          on)
459        - bugfix: notes triggered at position 0 in the audio buffer were
460          sometimes wrongly killed in the same buffer, causing no sound to
461          be played
462        - added support for chromatic / drumkit mode Roland GS Sysex message
463          which is usally used to switch a part between chromatic sounds and
464          drumkit sounds (as opposed to their common default setting of MIDI
465          part 10 being a drumkit part and all other ones chromatic parts), in
466          LS however one can switch between the first 16 MIDI instrument maps
467          defined for the sampler
468        - made it possible to create multiple sample channels even if the
469          audio thread isn't running
470        - fixed crash when removing channel with active voices (#116)
471        - bugfix: on sample reference changes (instrument editor), only
472          un-cache the respective sample if it's really not used by any
473          sampler engine anymore
474        - re-cache samples in case they were changed by an instrument editor,
475          e.g. when a sample was added while playing (#82)
476        - fixed hanging notes which occured when note-off event had the exact
477          same time stamp as the voice's note-on event and occured both in the
478          same audio fragment cycle (fixes bug #112)
479        - added support for the "fine tune" and "pitch bend range"
480          instrument-level gig parameters
481        - fixed minor artifacts in pitch bend handling
482        - added support for GS Reset SysEx message
483        - allow gig files to use unlimited downward pitch shifting
484        - added a limit check for upward pitch shifting
485        - bugfix: sometimes, when playing a note twice fast, the second
486          note was silent
487        - fixed crash happening when a pitch bend event arrived at the
488          same time a new instrument was loading
489    
490      * LSCP server:
491        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
492          react on MIDI data arriving on certain sampler channels (so far only
493          Note-On and Note-Off events are sent via this LSCP event)
494        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
495          react on MIDI data arriving on certain MIDI input devices (so far only
496          Note-On and Note-Off events are sent via this LSCP event)
497        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
498          SET DB_INSTRUMENT FILE_PATH
499        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
500          frontends to send MIDI messages to specific sampler channel
501        - added two additional fields to GET FILE INSTRUMENT INFO command -
502          KEY_BINDINGS and KEYSWITCH_BINDINGS
503        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
504          was incorrect
505        - Optimized the retrieval of the MIDI instrument mappings
506        - added new LSCP command "SET VOICES" to globally alter the maximum
507          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
508          be triggered respectively
509        - added new LSCP command "SET STREAMS" to globally alter the maximum
510          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
511          which will be triggered respectively
512        - bugfix: retry if "select" returns EINTR (this fixes a crash when
513          a gigedit file dialog is opened)
514        - close all connections when LSCPServer is deleted
515        - hard close of all sockets on exit
516        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
517          driver
518    
519      * Bug fixes:
520        - fixed a crash which occurs when removing a sampler channel waiting
521          to start instrument loading after another channel
522        - fixed a crash which occurs when removing a sampler channel with
523          instrument loading in progress (bug #113)
524        - fixed termination caused by uncaught exception when adding MIDI
525          instrument with PERSISTENT load mode
526        - fixed possible iterator invalidations when resetting the sampler
527        - fixed memory leaks when issuing the following LSCP commands:
528          GET AUDIO_OUTPUT_DRIVER INFO
529          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
530          GET MIDI_INPUT_DRIVER INFO
531          GET MIDI_INPUT_DRIVER_PARAMETER INFO
532        - fixed possible compilation error when sqlite is not present
533        - fixed orphaned pointers when setting maximum voices limit (bug #118)
534        - fixed crash when changing the audio output device of a sampler
535          channel with loaded instrument and start playing notes
536        - fixed endless loop in Engine::SuspendAll() (bug #120)
537        - fixed a low-level atomic load function that was broken on 64-bit
538          PowerPC, which probably could cause crashes on that platform
539        - fixed a memory management error which could cause a crash when a
540          plugin was unloaded
541        - bugfix: two private structs had the same name, which could cause
542          problems if the linker chose the wrong constructor
543        - fixed low-level ConditionServer usage bug that caused lockups on
544          Windows
545    
546    
547    Version 0.5.1 (6 December 2007)
548    
549      * packaging changes:
550        - added autoconf checks for pthread library
551        - added autoconf check for pthread bug found on certain NPTL-enabled
552          glibc versions (see Gentoo bug report #194076)
553        - added autoconf checks for MS Windows
554    
555      * general changes:
556        - bugfix: the thread used by an editor plugin didn't die when the
557          editor closed
558        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
559          out all the space. operator--() did not apply size_mask after
560          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
561          order to avoid problems with the _NonVolatileReader functions.
562        - bugfix: Stream.h: added a missing divide by BytesPerSample in
563          GetWriteSpace(). Since this function is currently only used in
564          the stream's qsort() compare function, it didn't trigger any
565          bugs.
566        - Resampler.h, Synthesizer.h: cubic interpolation now works in
567          24bit mode too. Faster method to read 24bit words on little
568          endian machines (x86): replaced 3 byte reads + shifts with a 1
569          unaligned 32bit read and shift
570        - experimental support for MS Windows (MIDI input via MME, AUDIO
571          output via ASIO)
572        - made handling of SIGINT signal (Ctrl-C) a bit more robust
573        - support for monitoring the total number of active disk streams
574          (new LSCP commands: GET TOTAL_STREAM_COUNT,
575          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
576    
577      * AUDIO driver:
578        - added Windows ASIO low latency audio driver
579    
580      * MIDI driver:
581        - added MME Windows MIDI driver
582    
583      * LSCP server:
584        - added support for Windows style path / filenames, however with
585          forward slash path separators instead of backslash
586          (i.e. "C:/foo/bar.gig")
587        - allow naughty liblscp to send non-string device parameters within
588          apostrophes as well
589        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
590          "LIST FILE INSTRUMENTS <file>" and
591          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
592          about an arbitrary instrument file on the system where the sampler is
593          running on
594    
595    Version 0.5.0 (15 October 2007)
596    
597      * packaging changes:
598        - config.h is not going to be installed along with liblinuxsampler's
599          API header files anymore
600        - only the API relevant header (and source) files will be exported to
601          the Doxygen API documentation (explicitly listed in Doxyfile.in)
602        - added completely new XCode project files for Mac OSX which is now
603          capable to execute our autoconf environment, thus no need anymore
604          to maintain the compile time configuration file (osx/version.h) for
605          OSX manually (patch by Toshi Nagata)
606        - fixed buggy boolean --enable-foo / --disable-foo configure script
607          parameters
608        - global.h now only covers global definitions that are needed for the
609          C++ API header files, all implementation internal global definitions
610          are now in global_private.h
611        - atomic.h is not exposed to the C++ API anymore
612        - no need to include config.h anymore for using LS's API header files
613        - fixed warnings in API doc generation
614    
615      * general changes:
616        - replaced the old, confusing MIDI program change mechanism by a
617          flexible MIDI instrument mapper which allows to map arbitrary
618          (MIDI bank, MIDI program) pairs with arbitrary
619          (engine type, instrument file, file index) triplets which will be
620          loaded on the respective channel when such MIDI program change
621          messages arrive, beside that, each entry allows to define a life-time
622          strategy for the instrument, so the user can define whether the
623          instrument should i.e. be permanently loaded (to be able to switch
624          quickly among sounds) or i.e. loaded just on demand when the
625          respective program change arrives (to safe RAM space), as well as a
626          global volume factor for each entry, so the user can adjust the volume
627          dynamic of his mapped instrument collection without having to modify
628          the instrument files, also one can manage arbitrary amount of such
629          MIDI instrument maps and assign each sampler channel individually
630          a certain map, so that i.e. separation of normal instruments and
631          drumkits is possible
632        - new notification events for tracking changes to audio/MIDI devices,
633          MIDI instrument maps, MIDI instruments, FX sends, global volume.
634        - sampler was limited to load max. 200 instruments in the background
635          due to a constant size RingBuffer FIFO which is now replaced by a
636          dynamic (unlimited) size std::list FIFO
637        - added FX sends, these allow to route audio signals to arbitrary audio
638          output channels for being processed by external effect processors
639          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
640          controllers
641        - global (sampler wide) volume can now be controlled at runtime
642        - Implemented new, improved notification system
643        - fixed compilation errors regarding OSX
644          (patch by Toshi Nagata)
645        - implemented instruments database
646        - added support for escape sequences to the instruments database
647        - added highly experimental support for on-the-fly instrument editing
648          within the sampler's process (by using instrument editor plugins),
649          you'll notice the new "Registered instrument editors:" message on
650          startup, added a new LSCP command:
651          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
652          to spawn a matching instrument editor for the instrument on the
653          given sampler channel, the plugin path can be overridden at compile
654          time with ./configure --enable-plugin-dir=/some/dir
655        - added experimental code for synchronizing instrument editors hosted
656          in the sampler's process to safely edit instruments while playing
657          without a crash (hopefully) by either suspending single regions
658          wherever possible or if unavoidable whole engine(s)
659        - fixed several issues in fundamental "Thread" class: set scheduling
660          policy and priority on thread level, set a minimum stack size for
661          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
662          threads simply inherited properties of starting thread instead of
663          setting their own policy and priority
664        - minor fix in our automatic stack trace mechanism on crashes, the
665          main process did not wait for the stack trace process to finish
666          its output
667        - fixed some minor memory leaks
668        - reenabled assembly features support, at the moment only for
669          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
670        - minor assembly fix in x86 features detection (don't use the PIC
671          register, to avoid relocations in the text segment at runtime)
672        - POSIX callback functions of Thread.h are hidden
673    
674      * MIDI driver:
675        - dispatch bank select (MSB and LSB) messages
676    
677      * audio driver:
678        - the ALSA audio output driver parameters now reflect the correct
679          parameter value ranges for the respective selected sound card
680          (patch by Till Wimmer, a bit fixed and extended)
681    
682      * Gigasampler format engine:
683        - if a filter is used and EG2 finishes before EG1, let the voice
684          die when EG2 has finished (this fixes a problem with clicks and
685          voice starvation for some gigs)
686        - playback is no longer disabled during instrument loading
687        - all notes playing on a channel that changes its instrument keep
688          playing with the old instrument until they get a note off
689          command
690        - EG fix: a release value of zero could cause noises or crash
691        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
692        - EG fine tuning: when attack is zero the EG starts at a level
693          above max sustain level, which means that there is a decay phase
694          even if sustain is 100%
695        - more EG fixes: the level could sometimes go below zero and cause
696          noises or crashes
697        - minor fix of EGDecay (patch by Toshi Nagata)
698        - fixed compiler error when --enable-override-filter-type was
699          supplied to the configure script (fixes #46)
700        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
701          instead of a fix value
702        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
703          127 (solo mode) only kill voices if the respective mode really
704          changed
705    
706      * LSCP server:
707        - fixed compile time error for old Bison versions
708          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
709        - parser now supports extended ASCII character set
710          (up to ASCII code 255, i.e. includes now umlauts and accents)
711        - filename arguments in LSCP commands now allow to use escape
712          sequences, that is directly literal as one of: \', \", \\, \n, \r,
713          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
714          code value like \xf2) (fixes bug #24)
715        - the following LSCP commands now also support escape sequences for at
716          least one of their text-based parameters (i.e. name, description):
717          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
718          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
719          "SET DB_INSTRUMENT_DIRECTORY NAME",
720          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
721          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
722          "FIND DB_INSTRUMENT_DIRECTORIES"
723        - returns verbose syntax errors (line and column where syntax error
724          occured, the unexpected character and the actually expected, possible
725          character(s), the latter only if less than 5 possibilities)
726        - made sure that LSCP syntax is not affected by gigedit locale
727          settings

732      * Bug fixes:
733        - fixed crash occurring on certain LSCP scripts (Bug 39)

739          device connected to a sampler channel to number less then or equal
740          to the index of the port to which the sampler channel is connected.
741        - The previous bindings were not been disconnected when altering
742          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
743          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
744        - The active stream/voice count statistic was incorrect.
745        - notification events were not been sent for some sampler
746          channel changes
747        - added default min and max values to restrict the number of allowed
748          audio output channels and MIDI input ports
749        - the connection to the PCM interface is now closed when destroying
750          an audio output device
751        - files with slash in their path or filename could not be loaded
752
