1  Version CVS HEAD (?)  Version CVS HEAD (?)
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

62        - fixed error when unloading instrument with same sample used by
63          multiple regions

79        - optimized sample lookup
80        - improved support for exclusive groups (group, off_by and
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

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

257          after MIDI/audio device creation failure
258

260    
261      * packaging changes:
262        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
263          causing e.g. the libgig test to fail when
264          "./configure --disable-jack-driver" was used
265          (patch by Alexis Ballier)

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

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

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

346          stereo
347        - added channel routing, fxsends and midi maps to the settings
348          stored in the plugin state
349        - performance optimization of AudioChannel::MixTo() and
350          AudioChannel::CopyTo() methods using GCC vector exensions
351          (if available)
352        - ASIO fixes: avoid initializing the device twice, avoid throwing
353          exception when getting parameters from a disconnected device
354    
355      * MIDI driver:
356        - added JACK MIDI driver
357        - dispatch bank select as ordinary CC as well, the user might seriously
358          want to (mis)use it for some purpose ("fixed" in all current MIDI
359          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
360        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
361          CoreMidi or AU
362        - fixed mingw-w64 compilation error in MME driver
363        - made program change handling in MIDI thread real-time safe by
364          moving the logic to a non-RT thread
365        - fixed minor memory leak in ALSA driver
366    
367      * instruments database:
368        - avoid time consuming samples scanning when adding instruments
369          to the instruments database
370        - added support for handling lost files in the instruments database
371        - Implemented option for adding instruments in separate directories
372          in the instruments database
373          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
374        - work-around for missing fnmatch function on Windows to make
375          instrument database compilable
376        - added instrument database support on Windows
377          works with both standalone mode and VST plugin.
378          the instruments DB file is located in
379          %USERPROFILE%\.linuxsampler\instruments.db which allows different
380          databases for each windows user
381          if no DB is present it automatically creates the .linuxsampler subdir
382          and then creates an empty DB
383        - fixed recursive import, which was broken on Windows
384    
385      * Gigasampler format engine:
386        - fixed a memory leak that could happen when a channel was deleted
387          while notes were playing
388        - made it possible to load an instrument even if the audio thread
389          isn't running
390        - added partial support for the "Controller Triggered" MIDI rule,
391          enough for piano gigs with pedal noise samples
392        - minor fix: only mark FX sends as being modified if really the
393          respective FX send MIDI controller was used
394        - added support for GM global device volume SysEx message
395          (can be selected at compile time to either apply globally to the
396          whole sampler [default] or only to the sampler channels that are
397          connected to the respective MIDI input port the SysEx message arrived
398          on)
399        - bugfix: notes triggered at position 0 in the audio buffer were
400          sometimes wrongly killed in the same buffer, causing no sound to
401          be played
402        - added support for chromatic / drumkit mode Roland GS Sysex message
403          which is usally used to switch a part between chromatic sounds and
404          drumkit sounds (as opposed to their common default setting of MIDI
405          part 10 being a drumkit part and all other ones chromatic parts), in
406          LS however one can switch between the first 16 MIDI instrument maps
407          defined for the sampler
408        - made it possible to create multiple sample channels even if the
409          audio thread isn't running
410        - fixed crash when removing channel with active voices (#116)
411        - bugfix: on sample reference changes (instrument editor), only
412          un-cache the respective sample if it's really not used by any
413          sampler engine anymore
414        - re-cache samples in case they were changed by an instrument editor,
415          e.g. when a sample was added while playing (#82)
416        - fixed hanging notes which occured when note-off event had the exact
417          same time stamp as the voice's note-on event and occured both in the
418          same audio fragment cycle (fixes bug #112)
419        - added support for the "fine tune" and "pitch bend range"
420          instrument-level gig parameters
421        - fixed minor artifacts in pitch bend handling
422        - added support for GS Reset SysEx message
423        - allow gig files to use unlimited downward pitch shifting
424        - added a limit check for upward pitch shifting
425        - bugfix: sometimes, when playing a note twice fast, the second
426          note was silent
427        - fixed crash happening when a pitch bend event arrived at the
428          same time a new instrument was loading
429    
430      * LSCP server:
431        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
432          react on MIDI data arriving on certain sampler channels (so far only
433          Note-On and Note-Off events are sent via this LSCP event)
434        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
435          react on MIDI data arriving on certain MIDI input devices (so far only
436          Note-On and Note-Off events are sent via this LSCP event)
437        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
438          SET DB_INSTRUMENT FILE_PATH
439        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
440          frontends to send MIDI messages to specific sampler channel
441        - added two additional fields to GET FILE INSTRUMENT INFO command -
442          KEY_BINDINGS and KEYSWITCH_BINDINGS
443        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
444          was incorrect
445        - Optimized the retrieval of the MIDI instrument mappings
446        - added new LSCP command "SET VOICES" to globally alter the maximum
447          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
448          be triggered respectively
449        - added new LSCP command "SET STREAMS" to globally alter the maximum
450          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
451          which will be triggered respectively
452        - bugfix: retry if "select" returns EINTR (this fixes a crash when
453          a gigedit file dialog is opened)
454        - close all connections when LSCPServer is deleted
455        - hard close of all sockets on exit
456        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
457          driver
458    
459      * Bug fixes:
460        - fixed a crash which occurs when removing a sampler channel waiting
461          to start instrument loading after another channel
462        - fixed a crash which occurs when removing a sampler channel with
463          instrument loading in progress (bug #113)
464        - fixed termination caused by uncaught exception when adding MIDI
465          instrument with PERSISTENT load mode
466        - fixed possible iterator invalidations when resetting the sampler
467        - fixed memory leaks when issuing the following LSCP commands:
468          GET AUDIO_OUTPUT_DRIVER INFO
469          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
470          GET MIDI_INPUT_DRIVER INFO
471          GET MIDI_INPUT_DRIVER_PARAMETER INFO
472        - fixed possible compilation error when sqlite is not present
473        - fixed orphaned pointers when setting maximum voices limit (bug #118)
474        - fixed crash when changing the audio output device of a sampler
475          channel with loaded instrument and start playing notes
476        - fixed endless loop in Engine::SuspendAll() (bug #120)
477        - fixed a low-level atomic load function that was broken on 64-bit
478          PowerPC, which probably could cause crashes on that platform
479        - fixed a memory management error which could cause a crash when a
480          plugin was unloaded
481        - bugfix: two private structs had the same name, which could cause
482          problems if the linker chose the wrong constructor
483        - fixed low-level ConditionServer usage bug that caused lockups on
484          Windows
485    
486    
487    Version 0.5.1 (6 December 2007)
488    
489      * packaging changes:
490        - added autoconf checks for pthread library
491        - added autoconf check for pthread bug found on certain NPTL-enabled
492          glibc versions (see Gentoo bug report #194076)
493        - added autoconf checks for MS Windows
494    
495      * general changes:
496        - bugfix: the thread used by an editor plugin didn't die when the
497          editor closed
498        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
499          out all the space. operator--() did not apply size_mask after
500          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
501          order to avoid problems with the _NonVolatileReader functions.
502        - bugfix: Stream.h: added a missing divide by BytesPerSample in
503          GetWriteSpace(). Since this function is currently only used in
504          the stream's qsort() compare function, it didn't trigger any
505          bugs.
506        - Resampler.h, Synthesizer.h: cubic interpolation now works in
507          24bit mode too. Faster method to read 24bit words on little
508          endian machines (x86): replaced 3 byte reads + shifts with a 1
509          unaligned 32bit read and shift
510        - experimental support for MS Windows (MIDI input via MME, AUDIO
511          output via ASIO)
512        - made handling of SIGINT signal (Ctrl-C) a bit more robust
513        - support for monitoring the total number of active disk streams
514          (new LSCP commands: GET TOTAL_STREAM_COUNT,
515          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
516    
517      * AUDIO driver:
518        - added Windows ASIO low latency audio driver
519    
520      * MIDI driver:
521        - added MME Windows MIDI driver
522    
523      * LSCP server:
524        - added support for Windows style path / filenames, however with
525          forward slash path separators instead of backslash
526          (i.e. "C:/foo/bar.gig")
527        - allow naughty liblscp to send non-string device parameters within
528          apostrophes as well
529        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
530          "LIST FILE INSTRUMENTS <file>" and
531          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
532          about an arbitrary instrument file on the system where the sampler is
533          running on
534    
535    Version 0.5.0 (15 October 2007)
536    
537      * packaging changes:
538        - config.h is not going to be installed along with liblinuxsampler's
539          API header files anymore
540        - only the API relevant header (and source) files will be exported to
541          the Doxygen API documentation (explicitly listed in Doxyfile.in)
542        - added completely new XCode project files for Mac OSX which is now
543          capable to execute our autoconf environment, thus no need anymore
544          to maintain the compile time configuration file (osx/version.h) for
545          OSX manually (patch by Toshi Nagata)
546        - fixed buggy boolean --enable-foo / --disable-foo configure script
547          parameters
548        - global.h now only covers global definitions that are needed for the
549          C++ API header files, all implementation internal global definitions
550          are now in global_private.h
551        - atomic.h is not exposed to the C++ API anymore
552        - no need to include config.h anymore for using LS's API header files
553        - fixed warnings in API doc generation
554    
555      * general changes:
556        - replaced the old, confusing MIDI program change mechanism by a
557          flexible MIDI instrument mapper which allows to map arbitrary
558          (MIDI bank, MIDI program) pairs with arbitrary
559          (engine type, instrument file, file index) triplets which will be
560          loaded on the respective channel when such MIDI program change
561          messages arrive, beside that, each entry allows to define a life-time
562          strategy for the instrument, so the user can define whether the
563          instrument should i.e. be permanently loaded (to be able to switch
564          quickly among sounds) or i.e. loaded just on demand when the
565          respective program change arrives (to safe RAM space), as well as a
566          global volume factor for each entry, so the user can adjust the volume
567          dynamic of his mapped instrument collection without having to modify
568          the instrument files, also one can manage arbitrary amount of such
569          MIDI instrument maps and assign each sampler channel individually
570          a certain map, so that i.e. separation of normal instruments and
571          drumkits is possible
572        - new notification events for tracking changes to audio/MIDI devices,
573          MIDI instrument maps, MIDI instruments, FX sends, global volume.
574        - sampler was limited to load max. 200 instruments in the background
575          due to a constant size RingBuffer FIFO which is now replaced by a
576          dynamic (unlimited) size std::list FIFO
577        - added FX sends, these allow to route audio signals to arbitrary audio
578          output channels for being processed by external effect processors
579          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
580          controllers
581        - global (sampler wide) volume can now be controlled at runtime
582        - Implemented new, improved notification system
583        - fixed compilation errors regarding OSX
584          (patch by Toshi Nagata)
585        - implemented instruments database
586        - added support for escape sequences to the instruments database
587        - added highly experimental support for on-the-fly instrument editing
588          within the sampler's process (by using instrument editor plugins),
589          you'll notice the new "Registered instrument editors:" message on
590          startup, added a new LSCP command:
591          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
592          to spawn a matching instrument editor for the instrument on the
593          given sampler channel, the plugin path can be overridden at compile
594          time with ./configure --enable-plugin-dir=/some/dir
595        - added experimental code for synchronizing instrument editors hosted
596          in the sampler's process to safely edit instruments while playing
597          without a crash (hopefully) by either suspending single regions
598          wherever possible or if unavoidable whole engine(s)
599        - fixed several issues in fundamental "Thread" class: set scheduling
600          policy and priority on thread level, set a minimum stack size for
601          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
602          threads simply inherited properties of starting thread instead of
603          setting their own policy and priority
604        - minor fix in our automatic stack trace mechanism on crashes, the
605          main process did not wait for the stack trace process to finish
606          its output
607        - fixed some minor memory leaks
608        - reenabled assembly features support, at the moment only for
609          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
610        - minor assembly fix in x86 features detection (don't use the PIC
611          register, to avoid relocations in the text segment at runtime)
612        - POSIX callback functions of Thread.h are hidden
613    
614      * MIDI driver:
615        - dispatch bank select (MSB and LSB) messages
616    
617      * audio driver:
618        - the ALSA audio output driver parameters now reflect the correct
619          parameter value ranges for the respective selected sound card
620          (patch by Till Wimmer, a bit fixed and extended)
621    
622      * Gigasampler format engine:
623        - if a filter is used and EG2 finishes before EG1, let the voice
624          die when EG2 has finished (this fixes a problem with clicks and
625          voice starvation for some gigs)
626        - playback is no longer disabled during instrument loading
627        - all notes playing on a channel that changes its instrument keep
628          playing with the old instrument until they get a note off
629          command
630        - EG fix: a release value of zero could cause noises or crash
631        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
632        - EG fine tuning: when attack is zero the EG starts at a level
633          above max sustain level, which means that there is a decay phase
634          even if sustain is 100%
635        - more EG fixes: the level could sometimes go below zero and cause
636          noises or crashes
637        - minor fix of EGDecay (patch by Toshi Nagata)
638        - fixed compiler error when --enable-override-filter-type was
639          supplied to the configure script (fixes #46)
640        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
641          instead of a fix value
642        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
643          127 (solo mode) only kill voices if the respective mode really
644          changed
645    
646      * LSCP server:
647        - fixed compile time error for old Bison versions
648          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
649        - parser now supports extended ASCII character set
650          (up to ASCII code 255, i.e. includes now umlauts and accents)
651        - filename arguments in LSCP commands now allow to use escape
652          sequences, that is directly literal as one of: \', \", \\, \n, \r,
653          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
654          code value like \xf2) (fixes bug #24)
655        - the following LSCP commands now also support escape sequences for at
656          least one of their text-based parameters (i.e. name, description):
657          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
658          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
659          "SET DB_INSTRUMENT_DIRECTORY NAME",
660          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
661          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
662          "FIND DB_INSTRUMENT_DIRECTORIES"
663        - returns verbose syntax errors (line and column where syntax error
664          occured, the unexpected character and the actually expected, possible
665          character(s), the latter only if less than 5 possibilities)
666        - made sure that LSCP syntax is not affected by gigedit locale
667          settings
668        - bugfix regarding strings parameter lists: all comma separated lists
669          of strings were treated as being one string containing commas
670          (fixes #57)
671    
672      * Bug fixes:
673        - fixed crash occurring on certain LSCP scripts (Bug 39)
674        - another thread safety fix for lscp "load engine" and "set
675          channel audio output device"
676        - fixed a crash which occurs when reassigning the same engine
677          on a sampler channel with connected MIDI device
678        - fixed a crash which occurs when changing the number of ports of a MIDI
679          device connected to a sampler channel to number less then or equal
680          to the index of the port to which the sampler channel is connected.
681        - The previous bindings were not been disconnected when altering
682          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
683          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
684        - The active stream/voice count statistic was incorrect.
685        - notification events were not been sent for some sampler
686          channel changes
687        - added default min and max values to restrict the number of allowed
688          audio output channels and MIDI input ports
689        - the connection to the PCM interface is now closed when destroying
690          an audio output device
691        - files with slash in their path or filename could not be loaded
692    
693      * test cases:
694        - updated and fixed (haven't been touched in a while)
695    
696    Version 0.4.0 (24 November 2006)

750        - added support for the "attenuation controller threshold" gig
751          parameter
752        - added smoothing of volume changes caused by control change
753          messages
754        - sample loop parameters are now taken from the DimensionRegion
755          instead of the wave chunk
756        - fixed keyswitching for v3 gigs with a number of keyswitch splits
757          not equal to a power of two
758        - reimplementation of the filter algorithm. The new filter is more
759          accurate and supports all gig filter types, including bandreject
760          and lowpass turbo.
761        - real support for 24 bit samples - samples are not truncated to
762          16 bits anymore
763        - support for aftertouch (channel pressure, not polyphonic
764          aftertouch)
765        - LFO1 behaviour fixed (dampening from max volume instead of
766          amplifying from 0)
