1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
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)

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        - Added new C++ API method Sampler::GetGlobalMaxVoices().
59        - Added new C++ API method Sampler::GetGlobalMaxStreams().
60        - Added new C++ API method Sampler::SetGlobalMaxVoices().

66    
67      * Gigasampler format engine:
68        - implemented the "round robin keyboard" dimension
69        - fixed round robin and random dimensions for cases when number of
70          dimension zones is not a power of two

72          key
73        - bugfix: pitch LFO controller "internal+aftertouch" was broken
74        - bugfix: filter keyboard tracking was broken
75        - filter performance fix (an unnecessary copy was made of the
76          filter parameters in each sub fragment)
77        - handle special case when pan parameter in gig file has max or
78          min value
79        - Exclusive Groups: don't ever stop voices of the same note,
80          doesn't sound naturally with a drumkit
81        - fixed EG1 modulation when attack or release is zero
82    
83      * SFZ format engine:
84        - Initial implementation (not usable yet)
85        - added support for v2 multiple stage envelope generators
86        - added a fine-tuned v1 envelope generator instead of using the
87          one from the gig engine

256          incorrectly set to two. This caused silence in Cubase 5.
257        - save engine type (gig, sfz or sf2) in plugin state
258        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
259          64 bit Windows

271        - thread safety fixes for the instrument loading thread
272        - LV2: use the new lv2 package if present
273        - VST: try to open Fantasia automatically on Linux and Mac too (on
274          Linux, the Fantasia jar should be placed in <prefix>/share/java)
275        - VST: fixed crashes on Linux Ardour and EnergyXT
276        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
277          port and audio channel routing for DSSI plugins are now visible.
278        - LV2: use urid and atom extensions instead of deprecated uri-map
279          and event
280        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
281        - LV2: changed number of output channels to 16 stereo, just like
282          the VST and AU plugins
283        - LV2: fixed save/restore of SFZ state (patch by David Robillard)

290          the ALSA sequencer client name
291        - removed limit of maximum amount of MIDI ports per MIDI device, since
292          there is no reason for this limit
293        - MME: fixed memory handling bug found with cppcheck
294        - MME: removed compiler warning
295        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
296          which allows to retrieve the list of CoreMIDI clients / ports and to connect
297          to them a la JACK, via the usual sampler APIs
298        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
299          the driver will automatically connect to other CoreMIDI clients' ports
300          (e.g. external MIDI devices being attached to the Mac)
301        - added support for MIDI note on velocity filter
302        - CoreMIDI: fixed memory deallocation error

351      * Bug fixes:
352        - Fixed crash which may occur when MIDI key + transpose is out of range
353        - minor valgrind fixes
354        - fixed crash which occurred when changing an already deployed sampler
355          channel to a different engine type
356        - fixed crash when deleting a sampler channel or changing engine
357          type while an instrument load was in progress
358        - bugfix: playing a note while changing the instrument could cause
359          a crash, or give "Handing back unknown region" error messages
360        - bugfix: calling SET VOICES (which Fantasia does on start and
361          refresh) could cause instruments to be unloaded
362        - Mac OS X: fixed name collision of enum in EffectControl and
363          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
364        - Mac OS X: fixed hanging threads
365        - Windows: disabled the previous thread fix on non-Mac systems, as
366          it caused hanging threads on Windows
367        - Fixed possible crashes due to corrupted MIDI/audio device list
368          after MIDI/audio device creation failure
369        - When creating MIDI instrument map entries with "PERSISTENT" type, the
370          instruments were uselessly precached with zero samples, however it still
371          took the full preloading time and on 1st program change the respective
372          instrument was completely reloaded again.
373        - fixed handling of rapid bank select and program change messages
374          sent to the same sampler channel (patch from the Open Octave
375          project, slightly adjusted)
376        - fixed crash when trying to create an effect instance with controls
377          which min and/or max values depend on the sample rate

385        - sfz/sf2 engine: fixed crash when using small audio fragment size
386        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
387        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
388          introduced in previous fix)
389        - fixed crash when a channel received a program change while
390          playing a note in a key group
391        - fixed erroneous error message piping in VoiceBase.h
392          (labelled "Disk stream not available in time")
393        - Update effects on sample rate & period size changes (to avoid
394          crashes and noise on such transitions).
395    
396    Version 1.0.0 (31 July 2009)
397    
398      * packaging changes:
399        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
400          causing e.g. the libgig test to fail when
401          "./configure --disable-jack-driver" was used
402          (patch by Alexis Ballier)
403        - fixed compilation with gcc 4.3
404        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
405        - fixed configure so it detects x86_64 (#107)
406        - fixes for building with newer MinGW versions
407        - fix for building with bison 2.4 (#111)
408        - fixed building with libgig installed in a non-standard directory
409        - minor fix in configure for mmsystem.h detection on MinGW
410        - Windows: look for editor plugins and Fantasia using base
411          directory of liblinuxsampler dll (look in the same directory and one
412          directory above)
413        - configure script fix: removed unconditional use of SSE
414        - fixed building with sqlite installed in a non-standard directory
415        - when cross-compiling, don't try to create instruments.db
416        - fix for new mingw-w64 version, which has usleep
417    
418      * general changes:
419        - bugfix: on some POSIX systems instrument editor plugins refused to
420          load as we used a non-portable Linux specific struct field
421          (fixes bug #70, patch by Ronald Baljeu)
422        - fixed endless loop which occured when loading an instrument editor
423          plugin DLL on Windows systems failed
424        - fixed memory leaks that occurred when liblinuxsampler was unloaded
425        - optimized the SynchronizedConfig class so it doesn't wait
426          unnecessarily long after an update
427        - added support for notifying instrument editors on note-on / note-off
428          events (e.g. to highlight the pressed keys on the virtual keyboard
429          of gigedit)
430        - added support for triggering notes by instrument editors (see above)
431        - be verbose on DLL load errors (on Linux)
432        - fixed di-harmonic triangle LFO implementation (this LFO implementation
433          is only used by very few systems, most pick the int math
434          implementation, which is usually faster)
435        - fixes for audio drivers with varying buffer sizes
436        - experimental support for running LinuxSampler as a DSSI, LV2 and
437          VST plugin
438        - notification events for stream/voice count statistics are now sent
439          only when there are actual changes
440        - added memory ordering constraints to improve stability on
441          multi-core and multi-cpu systems
442        - maximum voices and disk streams can now be altered at runtime
443        - fixed CPU feature detection on x86_64 (maybe fixes #108)
444        - automatic stacktrace mechanism is now turned off by default and can
445          be switched on by command line option "--stacktrace" (the automatic
446          stacktrace mechanism seems to be broken on most systems at the moment)
447        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
448          a pointer to the launched InstrumentEditor object
449        - added optional 3rd party user data parameter for following
450          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
451          InstrumentEditor::Launch(),
452          InstrumentManager::LaunchInstrumentEditor()
453        - theoretical fix: made SynchronizedConfig follow C++0x memory
454          model more strictly
455        - fixes for using large audio device buffers
456        - Windows: add the installation directory to the DLL search path
457          when loading an editor plugin (solves problems with VST and
458          gigedit on systems with other GTK versions installed)
459    
460      * audio driver:
461        - removed the nonsense audio channel constraint (which was hard coded to
462          max. 100 audio channels) for most audio drivers
463        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
464          opposed to the LSCP specs
465        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
466          reflected the wrong value
467        - fixed a memory management bug in ASIO driver
468        - Makefile fix: JACK_CFLAGS wasn't used
469        - JACK: use jack_client_open instead of the deprecated
470          jack_client_new
471        - added (experimental) CoreAudio driver
472        - applied old fixes to the ASIO driver that were included in the
473          previous binary release but accidentally never committed to CVS
474          (fixes #117)
475        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
476          win64)
477        - VST: added support for sample rate and buffer size changes
478        - VST: close editor (Fantasia) when the VST is removed
479        - VST: avoid opening Fantasia more than once for each VST instance
480        - VST: export main function as "main" on Linux too (fix for
481          energyXT)
482        - VST: changed number of output channels from one stereo to 16
483          stereo
484        - added channel routing, fxsends and midi maps to the settings
485          stored in the plugin state
486        - performance optimization of AudioChannel::MixTo() and
487          AudioChannel::CopyTo() methods using GCC vector exensions
488          (if available)
489        - ASIO fixes: avoid initializing the device twice, avoid throwing
490          exception when getting parameters from a disconnected device
491    
492      * MIDI driver:
493        - added JACK MIDI driver
494        - dispatch bank select as ordinary CC as well, the user might seriously
495          want to (mis)use it for some purpose ("fixed" in all current MIDI
496          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
497        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
498          CoreMidi or AU
499        - fixed mingw-w64 compilation error in MME driver
500        - made program change handling in MIDI thread real-time safe by
501          moving the logic to a non-RT thread
502        - fixed minor memory leak in ALSA driver
503    
504      * instruments database:
505        - avoid time consuming samples scanning when adding instruments
506          to the instruments database
507        - added support for handling lost files in the instruments database
508        - Implemented option for adding instruments in separate directories
509          in the instruments database
510          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
511        - work-around for missing fnmatch function on Windows to make
512          instrument database compilable
513        - added instrument database support on Windows
514          works with both standalone mode and VST plugin.
515          the instruments DB file is located in
516          %USERPROFILE%\.linuxsampler\instruments.db which allows different
517          databases for each windows user
518          if no DB is present it automatically creates the .linuxsampler subdir
519          and then creates an empty DB
520        - fixed recursive import, which was broken on Windows
521    
522      * Gigasampler format engine:
523        - fixed a memory leak that could happen when a channel was deleted
524          while notes were playing
525        - made it possible to load an instrument even if the audio thread
526          isn't running
527        - added partial support for the "Controller Triggered" MIDI rule,
528          enough for piano gigs with pedal noise samples
529        - minor fix: only mark FX sends as being modified if really the
530          respective FX send MIDI controller was used
531        - added support for GM global device volume SysEx message
532          (can be selected at compile time to either apply globally to the
533          whole sampler [default] or only to the sampler channels that are
534          connected to the respective MIDI input port the SysEx message arrived
535          on)
536        - bugfix: notes triggered at position 0 in the audio buffer were
537          sometimes wrongly killed in the same buffer, causing no sound to
538          be played
539        - added support for chromatic / drumkit mode Roland GS Sysex message
540          which is usally used to switch a part between chromatic sounds and
541          drumkit sounds (as opposed to their common default setting of MIDI
542          part 10 being a drumkit part and all other ones chromatic parts), in
543          LS however one can switch between the first 16 MIDI instrument maps
544          defined for the sampler
545        - made it possible to create multiple sample channels even if the
546          audio thread isn't running
547        - fixed crash when removing channel with active voices (#116)
548        - bugfix: on sample reference changes (instrument editor), only
549          un-cache the respective sample if it's really not used by any
550          sampler engine anymore
551        - re-cache samples in case they were changed by an instrument editor,
552          e.g. when a sample was added while playing (#82)
553        - fixed hanging notes which occured when note-off event had the exact
554          same time stamp as the voice's note-on event and occured both in the
555          same audio fragment cycle (fixes bug #112)
556        - added support for the "fine tune" and "pitch bend range"
557          instrument-level gig parameters
558        - fixed minor artifacts in pitch bend handling
559        - added support for GS Reset SysEx message
560        - allow gig files to use unlimited downward pitch shifting
561        - added a limit check for upward pitch shifting
562        - bugfix: sometimes, when playing a note twice fast, the second
563          note was silent
564        - fixed crash happening when a pitch bend event arrived at the
565          same time a new instrument was loading
566    
567      * LSCP server:
568        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
569          react on MIDI data arriving on certain sampler channels (so far only
570          Note-On and Note-Off events are sent via this LSCP event)
571        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
572          react on MIDI data arriving on certain MIDI input devices (so far only
573          Note-On and Note-Off events are sent via this LSCP event)
574        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
575          SET DB_INSTRUMENT FILE_PATH
576        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
577          frontends to send MIDI messages to specific sampler channel
578        - added two additional fields to GET FILE INSTRUMENT INFO command -
579          KEY_BINDINGS and KEYSWITCH_BINDINGS
580        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
581          was incorrect
582        - Optimized the retrieval of the MIDI instrument mappings
583        - added new LSCP command "SET VOICES" to globally alter the maximum
584          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
585          be triggered respectively
586        - added new LSCP command "SET STREAMS" to globally alter the maximum
587          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
588          which will be triggered respectively
589        - bugfix: retry if "select" returns EINTR (this fixes a crash when
590          a gigedit file dialog is opened)
591        - close all connections when LSCPServer is deleted
592        - hard close of all sockets on exit
593        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
594          driver
595    
596      * Bug fixes:
597        - fixed a crash which occurs when removing a sampler channel waiting
598          to start instrument loading after another channel
599        - fixed a crash which occurs when removing a sampler channel with
600          instrument loading in progress (bug #113)
601        - fixed termination caused by uncaught exception when adding MIDI
602          instrument with PERSISTENT load mode
603        - fixed possible iterator invalidations when resetting the sampler
604        - fixed memory leaks when issuing the following LSCP commands:
605          GET AUDIO_OUTPUT_DRIVER INFO
606          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
607          GET MIDI_INPUT_DRIVER INFO
608          GET MIDI_INPUT_DRIVER_PARAMETER INFO
609        - fixed possible compilation error when sqlite is not present
610        - fixed orphaned pointers when setting maximum voices limit (bug #118)
611        - fixed crash when changing the audio output device of a sampler
612          channel with loaded instrument and start playing notes
613        - fixed endless loop in Engine::SuspendAll() (bug #120)
614        - fixed a low-level atomic load function that was broken on 64-bit
615          PowerPC, which probably could cause crashes on that platform
616        - fixed a memory management error which could cause a crash when a
617          plugin was unloaded
618        - bugfix: two private structs had the same name, which could cause
619          problems if the linker chose the wrong constructor
620        - fixed low-level ConditionServer usage bug that caused lockups on
621          Windows
622
