3      * plugin changes:
4        - LV2 Persist + Files 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).

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          dimension zones is not a power of two
50        - made round robin use a counter for each region instead of each
51          key
52    
53      * SFZ format engine:
54        - Initial implementation (not usable yet)
55        - added support for v2 multiple stage envelope generators
56        - added a fine-tuned v1 envelope generator instead of using the

81          off_mode)
82        - added support for controller triggered regions (on_locc/on_hicc)
83        - added support for loop_mode=one_shot
84        - fixed playback of 16 bit wav files on big endian CPUs

250        - fixed crash when deleting a sampler channel or changing engine
251          type while an instrument load was in progress

253          a crash, or give "Handing back unknown region" error messages
254        - bugfix: calling SET VOICES (which Fantasia does on start and
255          refresh) could cause instruments to be unloaded

262          after MIDI/audio device creation failure
263    
264    Version 1.0.0 (31 July 2009)
265    
266      * packaging changes:
267        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
268          causing e.g. the libgig test to fail when
269          "./configure --disable-jack-driver" was used
270          (patch by Alexis Ballier)

279          directory of liblinuxsampler dll (look in the same directory and one
280          directory above)
281        - configure script fix: removed unconditional use of SSE
282        - fixed building with sqlite installed in a non-standard directory
283        - when cross-compiling, don't try to create instruments.db
284        - fix for new mingw-w64 version, which has usleep
285    
286      * general changes:
287        - bugfix: on some POSIX systems instrument editor plugins refused to
288          load as we used a non-portable Linux specific struct field
289          (fixes bug #70, patch by Ronald Baljeu)
290        - fixed endless loop which occured when loading an instrument editor
291          plugin DLL on Windows systems failed
292        - fixed memory leaks that occurred when liblinuxsampler was unloaded
293        - optimized the SynchronizedConfig class so it doesn't wait
294          unnecessarily long after an update
295        - added support for notifying instrument editors on note-on / note-off
296          events (e.g. to highlight the pressed keys on the virtual keyboard
297          of gigedit)
298        - added support for triggering notes by instrument editors (see above)
299        - be verbose on DLL load errors (on Linux)
300        - fixed di-harmonic triangle LFO implementation (this LFO implementation
301          is only used by very few systems, most pick the int math
302          implementation, which is usually faster)
303        - fixes for audio drivers with varying buffer sizes
304        - experimental support for running LinuxSampler as a DSSI, LV2 and
305          VST plugin
306        - notification events for stream/voice count statistics are now sent
307          only when there are actual changes

309          multi-core and multi-cpu systems
310        - maximum voices and disk streams can now be altered at runtime
311        - fixed CPU feature detection on x86_64 (maybe fixes #108)
312        - automatic stacktrace mechanism is now turned off by default and can
313          be switched on by command line option "--stacktrace" (the automatic
314          stacktrace mechanism seems to be broken on most systems at the moment)
315        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
316          a pointer to the launched InstrumentEditor object
317        - added optional 3rd party user data parameter for following
318          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
319          InstrumentEditor::Launch(),
320          InstrumentManager::LaunchInstrumentEditor()
321        - theoretical fix: made SynchronizedConfig follow C++0x memory
322          model more strictly
323        - fixes for using large audio device buffers
324        - Windows: add the installation directory to the DLL search path
325          when loading an editor plugin (solves problems with VST and
326          gigedit on systems with other GTK versions installed)
327    
328      * audio driver:
329        - removed the nonsense audio channel constraint (which was hard coded to
330          max. 100 audio channels) for most audio drivers
331        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
332          opposed to the LSCP specs
333        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
334          reflected the wrong value
335        - fixed a memory management bug in ASIO driver
336        - Makefile fix: JACK_CFLAGS wasn't used

338          jack_client_new
339        - added (experimental) CoreAudio driver
340        - applied old fixes to the ASIO driver that were included in the
341          previous binary release but accidentally never committed to CVS
342          (fixes #117)
343        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
344          win64)
345        - VST: added support for sample rate and buffer size changes
346        - VST: close editor (Fantasia) when the VST is removed
347        - VST: avoid opening Fantasia more than once for each VST instance

351          stereo
352        - added channel routing, fxsends and midi maps to the settings
353          stored in the plugin state
354        - performance optimization of AudioChannel::MixTo() and
355          AudioChannel::CopyTo() methods using GCC vector exensions
356          (if available)
357        - ASIO fixes: avoid initializing the device twice, avoid throwing
358          exception when getting parameters from a disconnected device
359    
360      * MIDI driver:
361        - added JACK MIDI driver
362        - dispatch bank select as ordinary CC as well, the user might seriously
363          want to (mis)use it for some purpose ("fixed" in all current MIDI
364          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
365        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
366          CoreMidi or AU
367        - fixed mingw-w64 compilation error in MME driver
368        - made program change handling in MIDI thread real-time safe by
369          moving the logic to a non-RT thread
370        - fixed minor memory leak in ALSA driver
371    
372      * instruments database:
373        - avoid time consuming samples scanning when adding instruments
374          to the instruments database
375        - added support for handling lost files in the instruments database
376        - Implemented option for adding instruments in separate directories
377          in the instruments database
378          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
379        - work-around for missing fnmatch function on Windows to make
380          instrument database compilable
381        - added instrument database support on Windows
382          works with both standalone mode and VST plugin.
383          the instruments DB file is located in
384          %USERPROFILE%\.linuxsampler\instruments.db which allows different
385          databases for each windows user
386          if no DB is present it automatically creates the .linuxsampler subdir
387          and then creates an empty DB
388        - fixed recursive import, which was broken on Windows
389    
390      * Gigasampler format engine:
391        - fixed a memory leak that could happen when a channel was deleted
392          while notes were playing
393        - made it possible to load an instrument even if the audio thread
394          isn't running
395        - added partial support for the "Controller Triggered" MIDI rule,
396          enough for piano gigs with pedal noise samples
397        - minor fix: only mark FX sends as being modified if really the
398          respective FX send MIDI controller was used
399        - added support for GM global device volume SysEx message
400          (can be selected at compile time to either apply globally to the
401          whole sampler [default] or only to the sampler channels that are
402          connected to the respective MIDI input port the SysEx message arrived
403          on)
404        - bugfix: notes triggered at position 0 in the audio buffer were
405          sometimes wrongly killed in the same buffer, causing no sound to
406          be played
407        - added support for chromatic / drumkit mode Roland GS Sysex message
408          which is usally used to switch a part between chromatic sounds and
409          drumkit sounds (as opposed to their common default setting of MIDI
410          part 10 being a drumkit part and all other ones chromatic parts), in
411          LS however one can switch between the first 16 MIDI instrument maps
412          defined for the sampler
413        - made it possible to create multiple sample channels even if the
414          audio thread isn't running
415        - fixed crash when removing channel with active voices (#116)
416        - bugfix: on sample reference changes (instrument editor), only
417          un-cache the respective sample if it's really not used by any
418          sampler engine anymore
419        - re-cache samples in case they were changed by an instrument editor,
420          e.g. when a sample was added while playing (#82)
421        - fixed hanging notes which occured when note-off event had the exact
422          same time stamp as the voice's note-on event and occured both in the
423          same audio fragment cycle (fixes bug #112)
424        - added support for the "fine tune" and "pitch bend range"
425          instrument-level gig parameters
426        - fixed minor artifacts in pitch bend handling
427        - added support for GS Reset SysEx message
428        - allow gig files to use unlimited downward pitch shifting
429        - added a limit check for upward pitch shifting
430        - bugfix: sometimes, when playing a note twice fast, the second
431          note was silent
432        - fixed crash happening when a pitch bend event arrived at the
433          same time a new instrument was loading
434    
435      * LSCP server:
436        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
437          react on MIDI data arriving on certain sampler channels (so far only
438          Note-On and Note-Off events are sent via this LSCP event)
439        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
440          react on MIDI data arriving on certain MIDI input devices (so far only
441          Note-On and Note-Off events are sent via this LSCP event)
442        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
443          SET DB_INSTRUMENT FILE_PATH
444        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
445          frontends to send MIDI messages to specific sampler channel
446        - added two additional fields to GET FILE INSTRUMENT INFO command -
447          KEY_BINDINGS and KEYSWITCH_BINDINGS
448        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
449          was incorrect
450        - Optimized the retrieval of the MIDI instrument mappings
451        - added new LSCP command "SET VOICES" to globally alter the maximum
452          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
453          be triggered respectively
454        - added new LSCP command "SET STREAMS" to globally alter the maximum
455          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
456          which will be triggered respectively
457        - bugfix: retry if "select" returns EINTR (this fixes a crash when
458          a gigedit file dialog is opened)
459        - close all connections when LSCPServer is deleted
460        - hard close of all sockets on exit
461        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
462          driver
463    
464      * Bug fixes:
465        - fixed a crash which occurs when removing a sampler channel waiting
466          to start instrument loading after another channel
467        - fixed a crash which occurs when removing a sampler channel with
468          instrument loading in progress (bug #113)
469        - fixed termination caused by uncaught exception when adding MIDI
470          instrument with PERSISTENT load mode
471        - fixed possible iterator invalidations when resetting the sampler
472        - fixed memory leaks when issuing the following LSCP commands:
473          GET AUDIO_OUTPUT_DRIVER INFO
474          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
475          GET MIDI_INPUT_DRIVER INFO
476          GET MIDI_INPUT_DRIVER_PARAMETER INFO
477        - fixed possible compilation error when sqlite is not present
478        - fixed orphaned pointers when setting maximum voices limit (bug #118)
479        - fixed crash when changing the audio output device of a sampler
480          channel with loaded instrument and start playing notes
481        - fixed endless loop in Engine::SuspendAll() (bug #120)
482        - fixed a low-level atomic load function that was broken on 64-bit
483          PowerPC, which probably could cause crashes on that platform
484        - fixed a memory management error which could cause a crash when a
485          plugin was unloaded
486        - bugfix: two private structs had the same name, which could cause
487          problems if the linker chose the wrong constructor
488        - fixed low-level ConditionServer usage bug that caused lockups on
489          Windows
490    
491    
492    Version 0.5.1 (6 December 2007)
493    
494      * packaging changes:
495        - added autoconf checks for pthread library
496        - added autoconf check for pthread bug found on certain NPTL-enabled
497          glibc versions (see Gentoo bug report #194076)
498        - added autoconf checks for MS Windows
499    
500      * general changes:
501        - bugfix: the thread used by an editor plugin didn't die when the
502          editor closed
503        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
504          out all the space. operator--() did not apply size_mask after
505          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
506          order to avoid problems with the _NonVolatileReader functions.
507        - bugfix: Stream.h: added a missing divide by BytesPerSample in
508          GetWriteSpace(). Since this function is currently only used in
509          the stream's qsort() compare function, it didn't trigger any
510          bugs.
511        - Resampler.h, Synthesizer.h: cubic interpolation now works in
512          24bit mode too. Faster method to read 24bit words on little
513          endian machines (x86): replaced 3 byte reads + shifts with a 1
514          unaligned 32bit read and shift
515        - experimental support for MS Windows (MIDI input via MME, AUDIO
516          output via ASIO)
517        - made handling of SIGINT signal (Ctrl-C) a bit more robust
518        - support for monitoring the total number of active disk streams
519          (new LSCP commands: GET TOTAL_STREAM_COUNT,
520          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
521    
522      * AUDIO driver:
523        - added Windows ASIO low latency audio driver
524    
525      * MIDI driver:
526        - added MME Windows MIDI driver
527    
528      * LSCP server:
529        - added support for Windows style path / filenames, however with
530          forward slash path separators instead of backslash
531          (i.e. "C:/foo/bar.gig")
532        - allow naughty liblscp to send non-string device parameters within
533          apostrophes as well
534        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
535          "LIST FILE INSTRUMENTS <file>" and
536          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
537          about an arbitrary instrument file on the system where the sampler is
538          running on
539    
540    Version 0.5.0 (15 October 2007)
541    
542      * packaging changes:
543        - config.h is not going to be installed along with liblinuxsampler's
544          API header files anymore
545        - only the API relevant header (and source) files will be exported to
546          the Doxygen API documentation (explicitly listed in Doxyfile.in)
547        - added completely new XCode project files for Mac OSX which is now
548          capable to execute our autoconf environment, thus no need anymore
549          to maintain the compile time configuration file (osx/version.h) for
550          OSX manually (patch by Toshi Nagata)
551        - fixed buggy boolean --enable-foo / --disable-foo configure script
552          parameters
553        - global.h now only covers global definitions that are needed for the
554          C++ API header files, all implementation internal global definitions
555          are now in global_private.h
556        - atomic.h is not exposed to the C++ API anymore
557        - no need to include config.h anymore for using LS's API header files
558        - fixed warnings in API doc generation
559    
560      * general changes:
561        - replaced the old, confusing MIDI program change mechanism by a
562          flexible MIDI instrument mapper which allows to map arbitrary
563          (MIDI bank, MIDI program) pairs with arbitrary
564          (engine type, instrument file, file index) triplets which will be
565          loaded on the respective channel when such MIDI program change
566          messages arrive, beside that, each entry allows to define a life-time
567          strategy for the instrument, so the user can define whether the
568          instrument should i.e. be permanently loaded (to be able to switch
569          quickly among sounds) or i.e. loaded just on demand when the
570          respective program change arrives (to safe RAM space), as well as a
571          global volume factor for each entry, so the user can adjust the volume
572          dynamic of his mapped instrument collection without having to modify
573          the instrument files, also one can manage arbitrary amount of such
574          MIDI instrument maps and assign each sampler channel individually
575          a certain map, so that i.e. separation of normal instruments and
576          drumkits is possible
577        - new notification events for tracking changes to audio/MIDI devices,
578          MIDI instrument maps, MIDI instruments, FX sends, global volume.
579        - sampler was limited to load max. 200 instruments in the background
580          due to a constant size RingBuffer FIFO which is now replaced by a
581          dynamic (unlimited) size std::list FIFO
582        - added FX sends, these allow to route audio signals to arbitrary audio
583          output channels for being processed by external effect processors
584          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
585          controllers
586        - global (sampler wide) volume can now be controlled at runtime
587        - Implemented new, improved notification system
588        - fixed compilation errors regarding OSX
589          (patch by Toshi Nagata)
590        - implemented instruments database
591        - added support for escape sequences to the instruments database
592        - added highly experimental support for on-the-fly instrument editing
593          within the sampler's process (by using instrument editor plugins),
594          you'll notice the new "Registered instrument editors:" message on
595          startup, added a new LSCP command:
596          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
597          to spawn a matching instrument editor for the instrument on the
598          given sampler channel, the plugin path can be overridden at compile
599          time with ./configure --enable-plugin-dir=/some/dir
600        - added experimental code for synchronizing instrument editors hosted
601          in the sampler's process to safely edit instruments while playing
602          without a crash (hopefully) by either suspending single regions
603          wherever possible or if unavoidable whole engine(s)
604        - fixed several issues in fundamental "Thread" class: set scheduling
605          policy and priority on thread level, set a minimum stack size for
606          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
607          threads simply inherited properties of starting thread instead of
608          setting their own policy and priority
609        - minor fix in our automatic stack trace mechanism on crashes, the
610          main process did not wait for the stack trace process to finish
611          its output
612        - fixed some minor memory leaks
613        - reenabled assembly features support, at the moment only for
614          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
615        - minor assembly fix in x86 features detection (don't use the PIC
616          register, to avoid relocations in the text segment at runtime)
617        - POSIX callback functions of Thread.h are hidden
618    
619      * MIDI driver:
620        - dispatch bank select (MSB and LSB) messages
621    
622      * audio driver:
623        - the ALSA audio output driver parameters now reflect the correct
624          parameter value ranges for the respective selected sound card
625          (patch by Till Wimmer, a bit fixed and extended)
626    
627      * Gigasampler format engine:
628        - if a filter is used and EG2 finishes before EG1, let the voice
629          die when EG2 has finished (this fixes a problem with clicks and
630          voice starvation for some gigs)
631        - playback is no longer disabled during instrument loading
632        - all notes playing on a channel that changes its instrument keep
633          playing with the old instrument until they get a note off
634          command
635        - EG fix: a release value of zero could cause noises or crash
636        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
637        - EG fine tuning: when attack is zero the EG starts at a level
638          above max sustain level, which means that there is a decay phase
639          even if sustain is 100%
640        - more EG fixes: the level could sometimes go below zero and cause
641          noises or crashes
642        - minor fix of EGDecay (patch by Toshi Nagata)
643        - fixed compiler error when --enable-override-filter-type was
644          supplied to the configure script (fixes #46)
645        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
646          instead of a fix value
647        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
648          127 (solo mode) only kill voices if the respective mode really
649          changed
650    
651      * LSCP server:
652        - fixed compile time error for old Bison versions
653          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
654        - parser now supports extended ASCII character set
655          (up to ASCII code 255, i.e. includes now umlauts and accents)
656        - filename arguments in LSCP commands now allow to use escape
657          sequences, that is directly literal as one of: \', \", \\, \n, \r,
658          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
659          code value like \xf2) (fixes bug #24)
660        - the following LSCP commands now also support escape sequences for at
661          least one of their text-based parameters (i.e. name, description):
662          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
663          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
664          "SET DB_INSTRUMENT_DIRECTORY NAME",
665          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
666          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
667          "FIND DB_INSTRUMENT_DIRECTORIES"
668        - returns verbose syntax errors (line and column where syntax error
669          occured, the unexpected character and the actually expected, possible
670          character(s), the latter only if less than 5 possibilities)
671        - made sure that LSCP syntax is not affected by gigedit locale
672          settings
673        - bugfix regarding strings parameter lists: all comma separated lists
674          of strings were treated as being one string containing commas
675          (fixes #57)
676    
677      * Bug fixes:
678        - fixed crash occurring on certain LSCP scripts (Bug 39)
679        - another thread safety fix for lscp "load engine" and "set
680          channel audio output device"
681        - fixed a crash which occurs when reassigning the same engine
682          on a sampler channel with connected MIDI device
683        - fixed a crash which occurs when changing the number of ports of a MIDI
684          device connected to a sampler channel to number less then or equal
685          to the index of the port to which the sampler channel is connected.
686        - The previous bindings were not been disconnected when altering
687          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
688          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
689        - The active stream/voice count statistic was incorrect.
690        - notification events were not been sent for some sampler
691          channel changes
692        - added default min and max values to restrict the number of allowed
693          audio output channels and MIDI input ports
694        - the connection to the PCM interface is now closed when destroying
695          an audio output device
696        - files with slash in their path or filename could not be loaded
697    
698      * test cases:
699        - updated and fixed (haven't been touched in a while)
