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        - modernized configure script
26            
27      * general changes:
28        - Refactoring: moved the independent code from
29          the Gigasampler format engine to base classes
30        - command line option '--profile' is currently disabled, since the
31          respective profiling code is currently broken
32        - Introduced support for optional environment variable
33          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34          where the sampler shall look for instrument editor plugins
35          (patch by Luis Garrido, slightly modified).
36        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39          note (in this implementation of the sampler its simply hard routed to
40          the 1st effect send of the sampler channel, no matter what the actual
41          effect type is)
42        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43          note (in this implementation of the sampler its simply hard routed to
44          the 2nd effect send of the sampler channel, no matter what the actual
45          effect type is)
46        - implemented support for internal LADSPA effects
47        - raised limit of program change queue from 100 to 512
48          (as suggested by Alex Stone)
49        - implemented sine LFO, pulse LFO and saw LFO
50        - experimental support for per voice equalization
51        - added command line option --exec-after-init
52        - Introduced new C++ API method:
53          EngineChannel::InstrumentFileName(int index)
54          allowing to retrieve the whole list of files used for the loaded
55          instrument on an engine channel (a.k.a. part). Some GigaStudio
56          instruments for example are splitted over several files like
57          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58    
59      * Gigasampler format engine:
60        - implemented the "round robin keyboard" dimension
61        - fixed round robin and random dimensions for cases when number of
62          dimension zones is not a power of two

75        - fixed error when unloading instrument with same sample used by
76          multiple regions

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

239        - VST bugfix: If the host called resume() before and after
240          changing sample rate or block size, the number of channels was
241          incorrectly set to two. This caused silence in Cubase 5.
242        - save engine type (gig, sfz or sf2) in plugin state
243        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
244          64 bit Windows
245        - AU: changed number of output channels from one stereo to 16
246          stereo

251          the plugin was loaded a second time (#174)
252        - plugin bugfix: instrument loading hang when the plugin was
253          loaded a second time (this time it's for Linux and Mac, previous
254          similar fix was for Windows)
255        - thread safety fixes for the instrument loading thread
256        - LV2: use the new lv2 package if present
257        - VST: try to open Fantasia automatically on Linux and Mac too (on
258          Linux, the Fantasia jar should be placed in <prefix>/share/java)
259        - VST: fixed crashes on Linux Ardour and EnergyXT
260        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
261          port and audio channel routing for DSSI plugins are now visible.
262        - LV2: use urid and atom extensions instead of deprecated uri-map
263          and event
264        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
265        - LV2: changed number of output channels to 16 stereo, just like
266          the VST and AU plugins
267        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
268        - LV2: made LV2 plugin buildable on Windows and Mac
269

274          there is no reason for this limit
275        - MME: fixed memory handling bug found with cppcheck
276        - MME: removed compiler warning
277        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
278          which allows to retrieve the list of CoreMIDI clients / ports and to connect
279          to them a la JACK, via the usual sampler APIs
280        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
281          the driver will automatically connect to other CoreMIDI clients' ports
282          (e.g. external MIDI devices being attached to the Mac)
283    
284      * audio driver:
285        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
286

334          refresh) could cause instruments to be unloaded
335        - Mac OS X: fixed name collision of enum in EffectControl and
336          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
337        - Mac OS X: fixed hanging threads
338        - Windows: disabled the previous thread fix on non-Mac systems, as
339          it caused hanging threads on Windows
340        - Fixed possible crashes due to corrupted MIDI/audio device list
341          after MIDI/audio device creation failure
342        - When creating MIDI instrument map entries with "PERSISTENT" type, the
343          instruments were uselessly precached with zero samples, however it still
344          took the full preloading time and on 1st program change the respective
345          instrument was completely reloaded again.
346        - fixed handling of rapid bank select and program change messages
347          sent to the same sampler channel (patch from the Open Octave
348          project, slightly adjusted)
349        - fixed crash when trying to create an effect instance with controls
350          which min and/or max values depend on the sample rate

353          multiple paths (#165)
354        - thread safety fixes for the instrument loading thread
355        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
356          (#176)
357        - more thread safety fixes for the instrument loading thread
358        - sfz/sf2 engine: fixed crash when using small audio fragment size
359        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
360        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
361          introduced in previous fix)
362        - fixed crash when a channel received a program change while
363          playing a note in a key group
364    
365    Version 1.0.0 (31 July 2009)
366    
367      * packaging changes:
368        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
369          causing e.g. the libgig test to fail when
370          "./configure --disable-jack-driver" was used
371          (patch by Alexis Ballier)
372        - fixed compilation with gcc 4.3
373        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
374        - fixed configure so it detects x86_64 (#107)
375        - fixes for building with newer MinGW versions
376        - fix for building with bison 2.4 (#111)
377        - fixed building with libgig installed in a non-standard directory
378        - minor fix in configure for mmsystem.h detection on MinGW
379        - Windows: look for editor plugins and Fantasia using base
380          directory of liblinuxsampler dll (look in the same directory and one
381          directory above)
382        - configure script fix: removed unconditional use of SSE
383        - fixed building with sqlite installed in a non-standard directory
384        - when cross-compiling, don't try to create instruments.db
385        - fix for new mingw-w64 version, which has usleep
386    
387      * general changes:
388        - bugfix: on some POSIX systems instrument editor plugins refused to
389          load as we used a non-portable Linux specific struct field
390          (fixes bug #70, patch by Ronald Baljeu)
391        - fixed endless loop which occured when loading an instrument editor
392          plugin DLL on Windows systems failed
393        - fixed memory leaks that occurred when liblinuxsampler was unloaded
394        - optimized the SynchronizedConfig class so it doesn't wait
395          unnecessarily long after an update
396        - added support for notifying instrument editors on note-on / note-off
397          events (e.g. to highlight the pressed keys on the virtual keyboard
398          of gigedit)
399        - added support for triggering notes by instrument editors (see above)
400        - be verbose on DLL load errors (on Linux)
401        - fixed di-harmonic triangle LFO implementation (this LFO implementation
402          is only used by very few systems, most pick the int math
403          implementation, which is usually faster)
404        - fixes for audio drivers with varying buffer sizes
405        - experimental support for running LinuxSampler as a DSSI, LV2 and
406          VST plugin
407        - notification events for stream/voice count statistics are now sent
408          only when there are actual changes
409        - added memory ordering constraints to improve stability on
410          multi-core and multi-cpu systems
411        - maximum voices and disk streams can now be altered at runtime
412        - fixed CPU feature detection on x86_64 (maybe fixes #108)
413        - automatic stacktrace mechanism is now turned off by default and can
414          be switched on by command line option "--stacktrace" (the automatic
415          stacktrace mechanism seems to be broken on most systems at the moment)
416        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
417          a pointer to the launched InstrumentEditor object
418        - added optional 3rd party user data parameter for following
419          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
420          InstrumentEditor::Launch(),
421          InstrumentManager::LaunchInstrumentEditor()
422        - theoretical fix: made SynchronizedConfig follow C++0x memory
423          model more strictly
424        - fixes for using large audio device buffers
425        - Windows: add the installation directory to the DLL search path
426          when loading an editor plugin (solves problems with VST and
427          gigedit on systems with other GTK versions installed)
428    
429      * audio driver:
430        - removed the nonsense audio channel constraint (which was hard coded to
431          max. 100 audio channels) for most audio drivers
432        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
433          opposed to the LSCP specs
434        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
435          reflected the wrong value
436        - fixed a memory management bug in ASIO driver
437        - Makefile fix: JACK_CFLAGS wasn't used
438        - JACK: use jack_client_open instead of the deprecated
439          jack_client_new
440        - added (experimental) CoreAudio driver
441        - applied old fixes to the ASIO driver that were included in the
442          previous binary release but accidentally never committed to CVS
443          (fixes #117)
444        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
445          win64)
446        - VST: added support for sample rate and buffer size changes
447        - VST: close editor (Fantasia) when the VST is removed
448        - VST: avoid opening Fantasia more than once for each VST instance
449        - VST: export main function as "main" on Linux too (fix for
450          energyXT)
451        - VST: changed number of output channels from one stereo to 16
452          stereo
453        - added channel routing, fxsends and midi maps to the settings
454          stored in the plugin state
455        - performance optimization of AudioChannel::MixTo() and
456          AudioChannel::CopyTo() methods using GCC vector exensions
457          (if available)
458        - ASIO fixes: avoid initializing the device twice, avoid throwing
459          exception when getting parameters from a disconnected device
460    
461      * MIDI driver:
462        - added JACK MIDI driver
463        - dispatch bank select as ordinary CC as well, the user might seriously
464          want to (mis)use it for some purpose ("fixed" in all current MIDI
465          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
466        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
467          CoreMidi or AU
468        - fixed mingw-w64 compilation error in MME driver
469        - made program change handling in MIDI thread real-time safe by
470          moving the logic to a non-RT thread
471        - fixed minor memory leak in ALSA driver
472    
473      * instruments database:
474        - avoid time consuming samples scanning when adding instruments
475          to the instruments database
476        - added support for handling lost files in the instruments database
477        - Implemented option for adding instruments in separate directories
478          in the instruments database
479          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
480        - work-around for missing fnmatch function on Windows to make
481          instrument database compilable
482        - added instrument database support on Windows
483          works with both standalone mode and VST plugin.
484          the instruments DB file is located in
485          %USERPROFILE%\.linuxsampler\instruments.db which allows different
486          databases for each windows user
487          if no DB is present it automatically creates the .linuxsampler subdir
488          and then creates an empty DB
489        - fixed recursive import, which was broken on Windows
490    
491      * Gigasampler format engine:
492        - fixed a memory leak that could happen when a channel was deleted
493          while notes were playing
494        - made it possible to load an instrument even if the audio thread
495          isn't running
496        - added partial support for the "Controller Triggered" MIDI rule,
497          enough for piano gigs with pedal noise samples
498        - minor fix: only mark FX sends as being modified if really the
499          respective FX send MIDI controller was used
500        - added support for GM global device volume SysEx message
501          (can be selected at compile time to either apply globally to the
502          whole sampler [default] or only to the sampler channels that are
503          connected to the respective MIDI input port the SysEx message arrived
504          on)
505        - bugfix: notes triggered at position 0 in the audio buffer were
506          sometimes wrongly killed in the same buffer, causing no sound to
507          be played
508        - added support for chromatic / drumkit mode Roland GS Sysex message
509          which is usally used to switch a part between chromatic sounds and
510          drumkit sounds (as opposed to their common default setting of MIDI
511          part 10 being a drumkit part and all other ones chromatic parts), in
512          LS however one can switch between the first 16 MIDI instrument maps
513          defined for the sampler
514        - made it possible to create multiple sample channels even if the
515          audio thread isn't running
516        - fixed crash when removing channel with active voices (#116)
517        - bugfix: on sample reference changes (instrument editor), only
518          un-cache the respective sample if it's really not used by any
519          sampler engine anymore
520        - re-cache samples in case they were changed by an instrument editor,
521          e.g. when a sample was added while playing (#82)
522        - fixed hanging notes which occured when note-off event had the exact
523          same time stamp as the voice's note-on event and occured both in the
524          same audio fragment cycle (fixes bug #112)
525        - added support for the "fine tune" and "pitch bend range"
526          instrument-level gig parameters
527        - fixed minor artifacts in pitch bend handling
528        - added support for GS Reset SysEx message
529        - allow gig files to use unlimited downward pitch shifting
530        - added a limit check for upward pitch shifting
531        - bugfix: sometimes, when playing a note twice fast, the second
532          note was silent
533        - fixed crash happening when a pitch bend event arrived at the
534          same time a new instrument was loading
535    
536      * LSCP server:
537        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
538          react on MIDI data arriving on certain sampler channels (so far only
539          Note-On and Note-Off events are sent via this LSCP event)
540        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
541          react on MIDI data arriving on certain MIDI input devices (so far only
542          Note-On and Note-Off events are sent via this LSCP event)
543        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
544          SET DB_INSTRUMENT FILE_PATH
545        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
546          frontends to send MIDI messages to specific sampler channel
547        - added two additional fields to GET FILE INSTRUMENT INFO command -
548          KEY_BINDINGS and KEYSWITCH_BINDINGS
549        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
550          was incorrect
551        - Optimized the retrieval of the MIDI instrument mappings
552        - added new LSCP command "SET VOICES" to globally alter the maximum
553          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
554          be triggered respectively
555        - added new LSCP command "SET STREAMS" to globally alter the maximum
556          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
557          which will be triggered respectively
558        - bugfix: retry if "select" returns EINTR (this fixes a crash when
559          a gigedit file dialog is opened)
560        - close all connections when LSCPServer is deleted
561        - hard close of all sockets on exit
562        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
563          driver
564    
565      * Bug fixes:
566        - fixed a crash which occurs when removing a sampler channel waiting
567          to start instrument loading after another channel
568        - fixed a crash which occurs when removing a sampler channel with
569          instrument loading in progress (bug #113)
570        - fixed termination caused by uncaught exception when adding MIDI
571          instrument with PERSISTENT load mode
572        - fixed possible iterator invalidations when resetting the sampler
573        - fixed memory leaks when issuing the following LSCP commands:
574          GET AUDIO_OUTPUT_DRIVER INFO
575          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
576          GET MIDI_INPUT_DRIVER INFO
577          GET MIDI_INPUT_DRIVER_PARAMETER INFO
578        - fixed possible compilation error when sqlite is not present
579        - fixed orphaned pointers when setting maximum voices limit (bug #118)
580        - fixed crash when changing the audio output device of a sampler
581          channel with loaded instrument and start playing notes
582        - fixed endless loop in Engine::SuspendAll() (bug #120)
583        - fixed a low-level atomic load function that was broken on 64-bit
584          PowerPC, which probably could cause crashes on that platform
585        - fixed a memory management error which could cause a crash when a
586          plugin was unloaded
587        - bugfix: two private structs had the same name, which could cause
588          problems if the linker chose the wrong constructor
589        - fixed low-level ConditionServer usage bug that caused lockups on
590          Windows
