2    
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

237          channel to a different engine type
238        - fixed crash when deleting a sampler channel or changing engine
239          type while an instrument load was in progress
240        - bugfix: playing a note while changing the instrument could cause
241          a crash, or give "Handing back unknown region" error messages
242        - bugfix: calling SET VOICES (which Fantasia does on start and
243          refresh) could cause instruments to be unloaded

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

250          after MIDI/audio device creation failure
251    
252    Version 1.0.0 (31 July 2009)
253    
254      * packaging changes:
255        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
256          causing e.g. the libgig test to fail when
257          "./configure --disable-jack-driver" was used
258          (patch by Alexis Ballier)

265        - minor fix in configure for mmsystem.h detection on MinGW
266        - Windows: look for editor plugins and Fantasia using base
267          directory of liblinuxsampler dll (look in the same directory and one
268          directory above)
269        - configure script fix: removed unconditional use of SSE
270        - fixed building with sqlite installed in a non-standard directory
271        - when cross-compiling, don't try to create instruments.db
272        - fix for new mingw-w64 version, which has usleep
273    
274      * general changes:
275        - bugfix: on some POSIX systems instrument editor plugins refused to
276          load as we used a non-portable Linux specific struct field
277          (fixes bug #70, patch by Ronald Baljeu)
278        - fixed endless loop which occured when loading an instrument editor
279          plugin DLL on Windows systems failed
280        - fixed memory leaks that occurred when liblinuxsampler was unloaded
281        - optimized the SynchronizedConfig class so it doesn't wait
282          unnecessarily long after an update
283        - added support for notifying instrument editors on note-on / note-off
284          events (e.g. to highlight the pressed keys on the virtual keyboard
285          of gigedit)
286        - added support for triggering notes by instrument editors (see above)
287        - be verbose on DLL load errors (on Linux)
288        - fixed di-harmonic triangle LFO implementation (this LFO implementation
289          is only used by very few systems, most pick the int math
290          implementation, which is usually faster)
291        - fixes for audio drivers with varying buffer sizes
292        - experimental support for running LinuxSampler as a DSSI, LV2 and
293          VST plugin
294        - notification events for stream/voice count statistics are now sent
295          only when there are actual changes

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

326          jack_client_new
327        - added (experimental) CoreAudio driver
328        - applied old fixes to the ASIO driver that were included in the
329          previous binary release but accidentally never committed to CVS
330          (fixes #117)
331        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
332          win64)
333        - VST: added support for sample rate and buffer size changes
334        - VST: close editor (Fantasia) when the VST is removed
335        - VST: avoid opening Fantasia more than once for each VST instance

343          AudioChannel::CopyTo() methods using GCC vector exensions
344          (if available)
345        - ASIO fixes: avoid initializing the device twice, avoid throwing
346          exception when getting parameters from a disconnected device
347    
348      * MIDI driver:
349        - added JACK MIDI driver
350        - dispatch bank select as ordinary CC as well, the user might seriously
351          want to (mis)use it for some purpose ("fixed" in all current MIDI
352          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
353        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
354          CoreMidi or AU
355        - fixed mingw-w64 compilation error in MME driver
356        - made program change handling in MIDI thread real-time safe by
357          moving the logic to a non-RT thread
358        - fixed minor memory leak in ALSA driver

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