35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37    
38      * general changes:
39        - Refactoring: moved the independent code from
40          the Gigasampler format engine to base classes
41        - command line option '--profile' is currently disabled, since the
42          respective profiling code is currently broken
43        - Introduced support for optional environment variable
44          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45          where the sampler shall look for instrument editor plugins
46          (patch by Luis Garrido, slightly modified).
47        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50          note (in this implementation of the sampler its simply hard routed to
51          the 1st effect send of the sampler channel, no matter what the actual
52          effect type is)
53        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54          note (in this implementation of the sampler its simply hard routed to
55          the 2nd effect send of the sampler channel, no matter what the actual
56          effect type is)
57        - implemented support for internal LADSPA effects
58        - raised limit of program change queue from 100 to 512
59          (as suggested by Alex Stone)
60        - implemented sine LFO, pulse LFO and saw LFO
61        - experimental support for per voice equalization
62        - added command line option --exec-after-init
63        - Introduced new C++ API method:
64          EngineChannel::InstrumentFileName(int index)
65          allowing to retrieve the whole list of files used for the loaded
66          instrument on an engine channel (a.k.a. part). Some GigaStudio
67          instruments for example are splitted over several files like
68          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69        - Added new C++ API method Sampler::GetGlobalMaxVoices().
70        - Added new C++ API method Sampler::GetGlobalMaxStreams().
71        - Added new C++ API method Sampler::SetGlobalMaxVoices().
72        - Added new C++ API method Sampler::SetGlobalMaxStreams().
73        - Various "const" and "restrict" optimizations.
74        - all engines: add pan CC value to instrument pan parameter before
75          applying panning, instead of using two separate pan functions in
76          series (#182)
77        - added a lock guard class for exception safe mutex handling and
78          used it everywhere appropriate
79        - Immediately apply scale tuning changes to active voices.
80        - Exposed scale tuning to C++ API (along to the already existing standard
81          SysEx way).
82        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83          and broken for ppc64. (Seq_cst loads and stores are actually not
84          used in LS, so the bug wasn't noticable.)
85        - lsatomic.h: added ARMv7 support
86        - Added support for multiple MIDI input ports per sampler channel (and
87          added various new C++ methods for this new feature / design change, old
88          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89          as deprecated but are still there and should provide full behavior
90          backward compatibility).
91        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92          unsafe and caused compilation error with clang 2.x).
93        - Bugfix: only process the latest MIDI program change event.
94        - Introducing the LSCP shell, which provides convenient control of the
95          sampler from the command line by providing LSCP aware features.
96    
97      * Gigasampler format engine:
98        - implemented the "round robin keyboard" dimension
99        - fixed round robin and random dimensions for cases when number of
100          dimension zones is not a power of two
101        - made round robin use a counter for each region instead of each
102          key
103        - bugfix: pitch LFO controller "internal+aftertouch" was broken
104        - bugfix: filter keyboard tracking was broken
105        - filter performance fix (an unnecessary copy was made of the
106          filter parameters in each sub fragment)
107        - handle special case when pan parameter in gig file has max or
108          min value
109        - Exclusive Groups: don't ever stop voices of the same note,
110          doesn't sound naturally with a drumkit
111        - fixed EG1 modulation when attack or release is zero
112    
113      * SFZ format engine:
114        - Initial implementation (not usable yet)
115        - added support for v2 multiple stage envelope generators
116        - added a fine-tuned v1 envelope generator instead of using the
117          one from the gig engine

119        - added support for trigger=first, trigger=legato and sw_previous
120        - allow non-numerical key values ("C#4" for example)

122        - fixed error when unloading instrument with same sample used by
123          multiple regions

283        - Listen to all interfaces on Mac OS X (INADDR_ANY)
284        - VST bugfix: If the host called resume() before and after
285          changing sample rate or block size, the number of channels was
286          incorrectly set to two. This caused silence in Cubase 5.
287        - save engine type (gig, sfz or sf2) in plugin state
288        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
289          64 bit Windows
290        - AU: changed number of output channels from one stereo to 16
291          stereo
292        - VST: made it possible to build the VST plugin for Mac

297          the plugin was loaded a second time (#174)
298        - plugin bugfix: instrument loading hang when the plugin was
299          loaded a second time (this time it's for Linux and Mac, previous
300          similar fix was for Windows)
301        - thread safety fixes for the instrument loading thread
302        - LV2: use the new lv2 package if present
303        - VST: try to open Fantasia automatically on Linux and Mac too (on
304          Linux, the Fantasia jar should be placed in <prefix>/share/java)
305        - VST: fixed crashes on Linux Ardour and EnergyXT
306        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
307          port and audio channel routing for DSSI plugins are now visible.
308        - LV2: use urid and atom extensions instead of deprecated uri-map
309          and event
310        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
311        - LV2: changed number of output channels to 16 stereo, just like
312          the VST and AU plugins
313        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
314        - LV2: made LV2 plugin buildable on Windows and Mac

319        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
320          the ALSA sequencer client name
321        - removed limit of maximum amount of MIDI ports per MIDI device, since
322          there is no reason for this limit
323        - MME: fixed memory handling bug found with cppcheck
324        - MME: removed compiler warning
325        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
326          which allows to retrieve the list of CoreMIDI clients / ports and to connect
327          to them a la JACK, via the usual sampler APIs
328        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
329          the driver will automatically connect to other CoreMIDI clients' ports
330          (e.g. external MIDI devices being attached to the Mac)
331        - added support for MIDI note on velocity filter

408          after MIDI/audio device creation failure
409        - When creating MIDI instrument map entries with "PERSISTENT" type, the
410          instruments were uselessly precached with zero samples, however it still
411          took the full preloading time and on 1st program change the respective
412          instrument was completely reloaded again.
413        - fixed handling of rapid bank select and program change messages
414          sent to the same sampler channel (patch from the Open Octave

436          (fixes #208)
437    
438    Version 1.0.0 (31 July 2009)
439    
440      * packaging changes:
441        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
442          causing e.g. the libgig test to fail when
443          "./configure --disable-jack-driver" was used
444          (patch by Alexis Ballier)

467        - optimized the SynchronizedConfig class so it doesn't wait
468          unnecessarily long after an update
469        - added support for notifying instrument editors on note-on / note-off
470          events (e.g. to highlight the pressed keys on the virtual keyboard
471          of gigedit)
472        - added support for triggering notes by instrument editors (see above)
473        - be verbose on DLL load errors (on Linux)
474        - fixed di-harmonic triangle LFO implementation (this LFO implementation
475          is only used by very few systems, most pick the int math
476          implementation, which is usually faster)
477        - fixes for audio drivers with varying buffer sizes
478        - experimental support for running LinuxSampler as a DSSI, LV2 and
479          VST plugin

486        - automatic stacktrace mechanism is now turned off by default and can
487          be switched on by command line option "--stacktrace" (the automatic
488          stacktrace mechanism seems to be broken on most systems at the moment)
489        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
490          a pointer to the launched InstrumentEditor object
491        - added optional 3rd party user data parameter for following
492          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
493          InstrumentEditor::Launch(),
494          InstrumentManager::LaunchInstrumentEditor()
495        - theoretical fix: made SynchronizedConfig follow C++0x memory

505        max. 100 audio channels) for most audio drivers        max. 100 audio channels) for most audio drivers
506        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
507          opposed to the LSCP specs
508        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
509          reflected the wrong value
510        - fixed a memory management bug in ASIO driver
511        - Makefile fix: JACK_CFLAGS wasn't used
512        - JACK: use jack_client_open instead of the deprecated
513          jack_client_new
514        - added (experimental) CoreAudio driver
515        - applied old fixes to the ASIO driver that were included in the
516          previous binary release but accidentally never committed to CVS
517          (fixes #117)
518        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
519          win64)
520        - VST: added support for sample rate and buffer size changes
521        - VST: close editor (Fantasia) when the VST is removed
522        - VST: avoid opening Fantasia more than once for each VST instance

524          energyXT)
525        - VST: changed number of output channels from one stereo to 16
526          stereo
527        - added channel routing, fxsends and midi maps to the settings
528          stored in the plugin state
529        - performance optimization of AudioChannel::MixTo() and
530          AudioChannel::CopyTo() methods using GCC vector exensions
531          (if available)
532        - ASIO fixes: avoid initializing the device twice, avoid throwing
533          exception when getting parameters from a disconnected device
534    
535      * MIDI driver:
536        - added JACK MIDI driver
537        - dispatch bank select as ordinary CC as well, the user might seriously
538          want to (mis)use it for some purpose ("fixed" in all current MIDI
539          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
540        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
541          CoreMidi or AU
542        - fixed mingw-w64 compilation error in MME driver
543        - made program change handling in MIDI thread real-time safe by
544          moving the logic to a non-RT thread
545        - fixed minor memory leak in ALSA driver
546    
547      * instruments database:
548        - avoid time consuming samples scanning when adding instruments
549          to the instruments database
550        - added support for handling lost files in the instruments database
551        - Implemented option for adding instruments in separate directories
552          in the instruments database
553          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
554        - work-around for missing fnmatch function on Windows to make
555          instrument database compilable
556        - added instrument database support on Windows
557          works with both standalone mode and VST plugin.
558          the instruments DB file is located in
559          %USERPROFILE%\.linuxsampler\instruments.db which allows different
560          databases for each windows user
561          if no DB is present it automatically creates the .linuxsampler subdir
562          and then creates an empty DB
563        - fixed recursive import, which was broken on Windows
564    
565      * Gigasampler format engine:
566        - fixed a memory leak that could happen when a channel was deleted
567          while notes were playing
568        - made it possible to load an instrument even if the audio thread
569          isn't running
570        - added partial support for the "Controller Triggered" MIDI rule,
571          enough for piano gigs with pedal noise samples
572        - minor fix: only mark FX sends as being modified if really the
573          respective FX send MIDI controller was used
574        - added support for GM global device volume SysEx message
575          (can be selected at compile time to either apply globally to the
576          whole sampler [default] or only to the sampler channels that are
577          connected to the respective MIDI input port the SysEx message arrived
578          on)
579        - bugfix: notes triggered at position 0 in the audio buffer were
580          sometimes wrongly killed in the same buffer, causing no sound to
581          be played
582        - added support for chromatic / drumkit mode Roland GS Sysex message
583          which is usally used to switch a part between chromatic sounds and
584          drumkit sounds (as opposed to their common default setting of MIDI
585          part 10 being a drumkit part and all other ones chromatic parts), in
586          LS however one can switch between the first 16 MIDI instrument maps
587          defined for the sampler
588        - made it possible to create multiple sample channels even if the
589          audio thread isn't running
590        - fixed crash when removing channel with active voices (#116)
591        - bugfix: on sample reference changes (instrument editor), only
592          un-cache the respective sample if it's really not used by any
593          sampler engine anymore
594        - re-cache samples in case they were changed by an instrument editor,
595          e.g. when a sample was added while playing (#82)
596        - fixed hanging notes which occured when note-off event had the exact
597          same time stamp as the voice's note-on event and occured both in the
598          same audio fragment cycle (fixes bug #112)
599        - added support for the "fine tune" and "pitch bend range"
600          instrument-level gig parameters
601        - fixed minor artifacts in pitch bend handling
602        - added support for GS Reset SysEx message
603        - allow gig files to use unlimited downward pitch shifting
604        - added a limit check for upward pitch shifting
605        - bugfix: sometimes, when playing a note twice fast, the second
606          note was silent
607        - fixed crash happening when a pitch bend event arrived at the
608          same time a new instrument was loading
609    
610      * LSCP server:
611        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
612          react on MIDI data arriving on certain sampler channels (so far only
613          Note-On and Note-Off events are sent via this LSCP event)
614        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
615          react on MIDI data arriving on certain MIDI input devices (so far only
616          Note-On and Note-Off events are sent via this LSCP event)
617        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
618          SET DB_INSTRUMENT FILE_PATH
619        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
620          frontends to send MIDI messages to specific sampler channel
621        - added two additional fields to GET FILE INSTRUMENT INFO command -
622          KEY_BINDINGS and KEYSWITCH_BINDINGS
623        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
624          was incorrect
625        - Optimized the retrieval of the MIDI instrument mappings
626        - added new LSCP command "SET VOICES" to globally alter the maximum
627          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
628          be triggered respectively
629        - added new LSCP command "SET STREAMS" to globally alter the maximum
630          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
631          which will be triggered respectively
632        - bugfix: retry if "select" returns EINTR (this fixes a crash when
633          a gigedit file dialog is opened)
634        - close all connections when LSCPServer is deleted
635        - hard close of all sockets on exit
636        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
637          driver
638    
639      * Bug fixes:
640        - fixed a crash which occurs when removing a sampler channel waiting
641          to start instrument loading after another channel
642        - fixed a crash which occurs when removing a sampler channel with
643          instrument loading in progress (bug #113)
644        - fixed termination caused by uncaught exception when adding MIDI
645          instrument with PERSISTENT load mode
646        - fixed possible iterator invalidations when resetting the sampler
647        - fixed memory leaks when issuing the following LSCP commands:
648          GET AUDIO_OUTPUT_DRIVER INFO
649          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
650          GET MIDI_INPUT_DRIVER INFO
651          GET MIDI_INPUT_DRIVER_PARAMETER INFO
652        - fixed possible compilation error when sqlite is not present
653        - fixed orphaned pointers when setting maximum voices limit (bug #118)
654        - fixed crash when changing the audio output device of a sampler
655          channel with loaded instrument and start playing notes
656        - fixed endless loop in Engine::SuspendAll() (bug #120)
657        - fixed a low-level atomic load function that was broken on 64-bit
658          PowerPC, which probably could cause crashes on that platform
659        - fixed a memory management error which could cause a crash when a
660          plugin was unloaded
661        - bugfix: two private structs had the same name, which could cause
662          problems if the linker chose the wrong constructor
663        - fixed low-level ConditionServer usage bug that caused lockups on
664          Windows
