2    
3      * plugin changes:
4        - LV2 "state" extension support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21        - fixed compilation with gcc 4.7
22        - fixed configure script error with old autoconf versions
23        - lsatomic.h: use gcc provided atomic functions if building with
24          gcc 4.7 and C++11
25    
26      * general changes:
27        - Refactoring: moved the independent code from
28          the Gigasampler format engine to base classes
29        - command line option '--profile' is currently disabled, since the
30          respective profiling code is currently broken
31        - Introduced support for optional environment variable
32          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33          where the sampler shall look for instrument editor plugins
34          (patch by Luis Garrido, slightly modified).
35        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 1st effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42          note (in this implementation of the sampler its simply hard routed to
43          the 2nd effect send of the sampler channel, no matter what the actual
44          effect type is)
45        - implemented support for internal LADSPA effects
46        - raised limit of program change queue from 100 to 512
47          (as suggested by Alex Stone)
48        - implemented sine LFO, pulse LFO and saw LFO
49        - experimental support for per voice equalization
50        - added command line option --exec-after-init
51        - Introduced new C++ API method:
52          EngineChannel::InstrumentFileName(int index)
53          allowing to retrieve the whole list of files used for the loaded
54          instrument on an engine channel (a.k.a. part). Some GigaStudio
55          instruments for example are splitted over several files like
56          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57    
58      * Gigasampler format engine:
59        - implemented the "round robin keyboard" dimension
60        - fixed round robin and random dimensions for cases when number of
61          dimension zones is not a power of two
62        - made round robin use a counter for each region instead of each
63          key
64

71        - added support for trigger=first, trigger=legato and sw_previous
72        - allow non-numerical key values ("C#4" for example)
73        - "key" opcode now sets pitch_keycenter too
74        - fixed error when unloading instrument with same sample used by
75          multiple regions
76        - added some opcode aliases, like loopmode for loop_mode, to be
77          more compatible
78        - added support for trigger=release and rt_decay
79        - added support for off_mode=normal

82        - added support for amp_veltrack and amp_velcurve_N
83        - fine-tuned the default velocity curve
84        - added support for transpose
85        - fixed crash when using sw_down/up
86        - improved logic for sw_lokey/hikey/up/down/last
87        - added more v1 aliases to parser

307      * Bug fixes:
308        - Fixed crash which may occur when MIDI key + transpose is out of range
309        - minor valgrind fixes

311          channel to a different engine type
312        - fixed crash when deleting a sampler channel or changing engine
313          type while an instrument load was in progress
314        - bugfix: playing a note while changing the instrument could cause
315          a crash, or give "Handing back unknown region" error messages
316        - bugfix: calling SET VOICES (which Fantasia does on start and
317          refresh) could cause instruments to be unloaded

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

322          it caused hanging threads on Windows
323        - Fixed possible crashes due to corrupted MIDI/audio device list
324          after MIDI/audio device creation failure
325        - When creating MIDI instrument map entries with "PERSISTENT" type, the
326          instruments were uselessly precached with zero samples, however it still
327          took the full preloading time and on 1st program change the respective
328          instrument was completely reloaded again.
329        - fixed handling of rapid bank select and program change messages
330          sent to the same sampler channel (patch from the Open Octave
331          project, slightly adjusted)

333          which min and/or max values depend on the sample rate
334        - fixed bug #162
335        - bugfix: LADSPA_PATH was not evaluated correctly when containing
336          multiple paths (#165)
337        - thread safety fixes for the instrument loading thread
338        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
339          (#176)
340        - more thread safety fixes for the instrument loading thread
341        - sfz/sf2 engine: fixed crash when using small audio fragment size
342    
343    Version 1.0.0 (31 July 2009)
344    
345      * packaging changes:
346        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
347          causing e.g. the libgig test to fail when
348          "./configure --disable-jack-driver" was used
349          (patch by Alexis Ballier)
350        - fixed compilation with gcc 4.3
351        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
352        - fixed configure so it detects x86_64 (#107)
353        - fixes for building with newer MinGW versions
354        - fix for building with bison 2.4 (#111)
355        - fixed building with libgig installed in a non-standard directory
356        - minor fix in configure for mmsystem.h detection on MinGW
357        - Windows: look for editor plugins and Fantasia using base
358          directory of liblinuxsampler dll (look in the same directory and one
359          directory above)
360        - configure script fix: removed unconditional use of SSE
361        - fixed building with sqlite installed in a non-standard directory
362        - when cross-compiling, don't try to create instruments.db
363        - fix for new mingw-w64 version, which has usleep
364    
365      * general changes:
366        - bugfix: on some POSIX systems instrument editor plugins refused to
367          load as we used a non-portable Linux specific struct field
368          (fixes bug #70, patch by Ronald Baljeu)
369        - fixed endless loop which occured when loading an instrument editor
370          plugin DLL on Windows systems failed
371        - fixed memory leaks that occurred when liblinuxsampler was unloaded
372        - optimized the SynchronizedConfig class so it doesn't wait
373          unnecessarily long after an update
374        - added support for notifying instrument editors on note-on / note-off
375          events (e.g. to highlight the pressed keys on the virtual keyboard
376          of gigedit)
377        - added support for triggering notes by instrument editors (see above)
378        - be verbose on DLL load errors (on Linux)
379        - fixed di-harmonic triangle LFO implementation (this LFO implementation
380          is only used by very few systems, most pick the int math
381          implementation, which is usually faster)
382        - fixes for audio drivers with varying buffer sizes
383        - experimental support for running LinuxSampler as a DSSI, LV2 and
384          VST plugin
385        - notification events for stream/voice count statistics are now sent
386          only when there are actual changes
387        - added memory ordering constraints to improve stability on
388          multi-core and multi-cpu systems
389        - maximum voices and disk streams can now be altered at runtime
390        - fixed CPU feature detection on x86_64 (maybe fixes #108)
391        - automatic stacktrace mechanism is now turned off by default and can
392          be switched on by command line option "--stacktrace" (the automatic
393          stacktrace mechanism seems to be broken on most systems at the moment)
394        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
395          a pointer to the launched InstrumentEditor object
396        - added optional 3rd party user data parameter for following
397          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
398          InstrumentEditor::Launch(),
399          InstrumentManager::LaunchInstrumentEditor()
400        - theoretical fix: made SynchronizedConfig follow C++0x memory
401          model more strictly
402        - fixes for using large audio device buffers
403        - Windows: add the installation directory to the DLL search path
404          when loading an editor plugin (solves problems with VST and
405          gigedit on systems with other GTK versions installed)
406    
407      * audio driver:
408        - removed the nonsense audio channel constraint (which was hard coded to
409          max. 100 audio channels) for most audio drivers
410        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
411          opposed to the LSCP specs
412        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
413          reflected the wrong value
414        - fixed a memory management bug in ASIO driver
415        - Makefile fix: JACK_CFLAGS wasn't used
416        - JACK: use jack_client_open instead of the deprecated
417          jack_client_new
418        - added (experimental) CoreAudio driver
419        - applied old fixes to the ASIO driver that were included in the
420          previous binary release but accidentally never committed to CVS
421          (fixes #117)
422        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
423          win64)
424        - VST: added support for sample rate and buffer size changes
425        - VST: close editor (Fantasia) when the VST is removed
426        - VST: avoid opening Fantasia more than once for each VST instance
427        - VST: export main function as "main" on Linux too (fix for
428          energyXT)
429        - VST: changed number of output channels from one stereo to 16
430          stereo
431        - added channel routing, fxsends and midi maps to the settings
432          stored in the plugin state
433        - performance optimization of AudioChannel::MixTo() and
434          AudioChannel::CopyTo() methods using GCC vector exensions
435          (if available)
436        - ASIO fixes: avoid initializing the device twice, avoid throwing
437          exception when getting parameters from a disconnected device
438    
439      * MIDI driver:
440        - added JACK MIDI driver
441        - dispatch bank select as ordinary CC as well, the user might seriously
442          want to (mis)use it for some purpose ("fixed" in all current MIDI
443          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
444        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
445          CoreMidi or AU
446        - fixed mingw-w64 compilation error in MME driver
447        - made program change handling in MIDI thread real-time safe by
448          moving the logic to a non-RT thread
449        - fixed minor memory leak in ALSA driver
450    
451      * instruments database:
452        - avoid time consuming samples scanning when adding instruments
453          to the instruments database
454        - added support for handling lost files in the instruments database
455        - Implemented option for adding instruments in separate directories
456          in the instruments database
457          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
458        - work-around for missing fnmatch function on Windows to make
459          instrument database compilable
460        - added instrument database support on Windows
461          works with both standalone mode and VST plugin.
462          the instruments DB file is located in
463          %USERPROFILE%\.linuxsampler\instruments.db which allows different
464          databases for each windows user
465          if no DB is present it automatically creates the .linuxsampler subdir
466          and then creates an empty DB
467        - fixed recursive import, which was broken on Windows
468    
469      * Gigasampler format engine:
470        - fixed a memory leak that could happen when a channel was deleted
471          while notes were playing
472        - made it possible to load an instrument even if the audio thread
473          isn't running
474        - added partial support for the "Controller Triggered" MIDI rule,
475          enough for piano gigs with pedal noise samples
476        - minor fix: only mark FX sends as being modified if really the
477          respective FX send MIDI controller was used
478        - added support for GM global device volume SysEx message
479          (can be selected at compile time to either apply globally to the
480          whole sampler [default] or only to the sampler channels that are
481          connected to the respective MIDI input port the SysEx message arrived
482          on)
483        - bugfix: notes triggered at position 0 in the audio buffer were
484          sometimes wrongly killed in the same buffer, causing no sound to
485          be played
486        - added support for chromatic / drumkit mode Roland GS Sysex message
487          which is usally used to switch a part between chromatic sounds and
488          drumkit sounds (as opposed to their common default setting of MIDI
489          part 10 being a drumkit part and all other ones chromatic parts), in
490          LS however one can switch between the first 16 MIDI instrument maps
491          defined for the sampler
492        - made it possible to create multiple sample channels even if the
493          audio thread isn't running
494        - fixed crash when removing channel with active voices (#116)
495        - bugfix: on sample reference changes (instrument editor), only
496          un-cache the respective sample if it's really not used by any
497          sampler engine anymore
498        - re-cache samples in case they were changed by an instrument editor,
499          e.g. when a sample was added while playing (#82)
500        - fixed hanging notes which occured when note-off event had the exact
501          same time stamp as the voice's note-on event and occured both in the
502          same audio fragment cycle (fixes bug #112)
503        - added support for the "fine tune" and "pitch bend range"
504          instrument-level gig parameters
505        - fixed minor artifacts in pitch bend handling
506        - added support for GS Reset SysEx message
507        - allow gig files to use unlimited downward pitch shifting
508        - added a limit check for upward pitch shifting
509        - bugfix: sometimes, when playing a note twice fast, the second
510          note was silent
511        - fixed crash happening when a pitch bend event arrived at the
512          same time a new instrument was loading
513    
514      * LSCP server:
515        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
516          react on MIDI data arriving on certain sampler channels (so far only
517          Note-On and Note-Off events are sent via this LSCP event)
518        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
519          react on MIDI data arriving on certain MIDI input devices (so far only
520          Note-On and Note-Off events are sent via this LSCP event)
521        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
522          SET DB_INSTRUMENT FILE_PATH
523        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
524          frontends to send MIDI messages to specific sampler channel
525        - added two additional fields to GET FILE INSTRUMENT INFO command -
526          KEY_BINDINGS and KEYSWITCH_BINDINGS
527        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
528          was incorrect
529        - Optimized the retrieval of the MIDI instrument mappings
530        - added new LSCP command "SET VOICES" to globally alter the maximum
531          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
532          be triggered respectively
533        - added new LSCP command "SET STREAMS" to globally alter the maximum
534          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
535          which will be triggered respectively
536        - bugfix: retry if "select" returns EINTR (this fixes a crash when
537          a gigedit file dialog is opened)
538        - close all connections when LSCPServer is deleted
539        - hard close of all sockets on exit
540        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
541          driver
542    
543      * Bug fixes:
544        - fixed a crash which occurs when removing a sampler channel waiting
545          to start instrument loading after another channel
546        - fixed a crash which occurs when removing a sampler channel with
547          instrument loading in progress (bug #113)
548        - fixed termination caused by uncaught exception when adding MIDI
549          instrument with PERSISTENT load mode
550        - fixed possible iterator invalidations when resetting the sampler
551        - fixed memory leaks when issuing the following LSCP commands:
552          GET AUDIO_OUTPUT_DRIVER INFO
553          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
554          GET MIDI_INPUT_DRIVER INFO
555          GET MIDI_INPUT_DRIVER_PARAMETER INFO
556        - fixed possible compilation error when sqlite is not present
557        - fixed orphaned pointers when setting maximum voices limit (bug #118)
558        - fixed crash when changing the audio output device of a sampler
559          channel with loaded instrument and start playing notes
560        - fixed endless loop in Engine::SuspendAll() (bug #120)
561        - fixed a low-level atomic load function that was broken on 64-bit
562          PowerPC, which probably could cause crashes on that platform
563        - fixed a memory management error which could cause a crash when a
564          plugin was unloaded
565        - bugfix: two private structs had the same name, which could cause
566          problems if the linker chose the wrong constructor
567        - fixed low-level ConditionServer usage bug that caused lockups on
568          Windows
569    
570    
571    Version 0.5.1 (6 December 2007)
572    
573      * packaging changes:
574        - added autoconf checks for pthread library
575        - added autoconf check for pthread bug found on certain NPTL-enabled
576          glibc versions (see Gentoo bug report #194076)
577        - added autoconf checks for MS Windows
578    
579      * general changes:
580        - bugfix: the thread used by an editor plugin didn't die when the
581          editor closed
582        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
583          out all the space. operator--() did not apply size_mask after
584          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
585          order to avoid problems with the _NonVolatileReader functions.
586        - bugfix: Stream.h: added a missing divide by BytesPerSample in
587          GetWriteSpace(). Since this function is currently only used in
588          the stream's qsort() compare function, it didn't trigger any
589          bugs.
590        - Resampler.h, Synthesizer.h: cubic interpolation now works in
591          24bit mode too. Faster method to read 24bit words on little
592          endian machines (x86): replaced 3 byte reads + shifts with a 1
593          unaligned 32bit read and shift
594        - experimental support for MS Windows (MIDI input via MME, AUDIO
595          output via ASIO)
596        - made handling of SIGINT signal (Ctrl-C) a bit more robust
597        - support for monitoring the total number of active disk streams
598          (new LSCP commands: GET TOTAL_STREAM_COUNT,
599          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
600    
601      * AUDIO driver:
602        - added Windows ASIO low latency audio driver
603    
604      * MIDI driver:
605        - added MME Windows MIDI driver
606    
607      * LSCP server:
608        - added support for Windows style path / filenames, however with
609          forward slash path separators instead of backslash
610          (i.e. "C:/foo/bar.gig")
611        - allow naughty liblscp to send non-string device parameters within
612          apostrophes as well
613        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
614          "LIST FILE INSTRUMENTS <file>" and
615          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
616          about an arbitrary instrument file on the system where the sampler is
617          running on
