# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5    
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
9        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10          allowing to sort data efficiently in real-time safe manner.
11        - RTList class: added methods for moving/inserting elements to arbitrary
12          position within a list.
13        - RTList class: added method fromPtr() for creating an Iterator object from
14          a raw element pointer.
15        - Attempt to partly fix resetting engine channels vs. resetting engine, an
16          overall cleanup of the Reset*(), ConnectAudioDevice(),
17          DisconnectAudioDevice() API methods would still be desirable though,
18          because the current situation is still inconsistent and error prone.
19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27    
28      * packaging changes:
29        - removed unnecessary dependency to libuuid
30          (originated by libgig's usage of it)
31        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32          auto detect whether it (sh/c)ould output its messages in color.
33    
34      * Real-time instrument scripts:
35        - Implemented scheduler for delayed MIDI events and for suspended scripts.
36        - Built-in script function "wait()": implemented support for function's
37          "duration-us" argument, thus scripts using this function are now
38          correctly resumed after the requested amount of microseconds.
39        - Built-in script function "play_note()": implemented support for
40          function's "duration-us" argument, thus notes triggered with this
41          argument are now correctly released after the requested amount of
42          microseconds.
43        - Fix: script events were not cleared when engine channel was reset,
44          potentially causing undefined behavior.
45        - Fixed crash which happened when trying to reference an undeclared
46          variable.
47        - Built-in script function "play_note()": Added support for passing
48          special value -1 for "duration-us" argument, which will cause the
49          triggered note to be released once the original note was released.
50        - Instrument script classes now exported with the liblinuxsampler C++ API.
51        - Added new API method ScriptVM::syntaxHighlighting() which provides
52          a convenient syntax highlighting backend for external instrument
53          script editor applications.
54        - Added new C++ API class "ScriptVMFactory".
55        - Extended parser issues to provide not only first line and first
56          column, but also last line and last column of issue (thus marking
57          the precise span of the issue within the source code).
58        - Reload script automatically after being modified by an instrument
59          editor.
60        - NKSP language grammar correction: allow empty event handler bodies
61          like "on note end on".
62        - Implemented built-in script function "change_vol()".
63        - Implemented built-in script function "change_tune()".
64        - Implemented built-in script function "change_pan()".
65        - Implemented built-in script function "change_cutoff()".
66        - Implemented built-in script function "change_reso()".
67        - Implemented built-in script function "event_status()".
68        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70          "event_status()" function.
71        - NKSP language: Added support for bitwise operators ".or.", ".and."
72          and ".not.".
73        - NKSP language scanner: Fixed IDs matching to require at least one
74          character (i.e. when matching function names or variable names).
75        - NKSP language scanner: disabled unusued rules.
76        - Fixed behavior of play_note() and note_off() functions which must
77          be distinguished engine internally from "real" MIDI note on/off
78          events in order to avoid misbehaviors like hanging notes.
79        - Implemented built-in script variable "$KSP_TIMER".
80        - Implemented built-in script variable "$NKSP_REAL_TIMER".
81        - Implemented built-in script variable "$NKSP_PERF_TIMER".
82        - Implemented built-in script variable "$ENGINE_UPTIME".
83        - Implemented built-in script function "inc()".
84        - Implemented built-in script function "dec()".
85        - NKSP language fix: division expressions were evaluated too often.
86        - NKSP language fix: string concatenation operator was right
87          associative instead of left (to right).
88        - NKSP language correction: allow empty statements in entire language
89          (i.e. "if end if").
90        - Implemented built-in script function "stop_wait()".
91        - Implemented built-in script variable "$NI_CALLBACK_ID".
92        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
93        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
94        - Added support for read-only built-in variables (respectively
95          handled by the script parser).
96        - Added built-in script constant "$NI_CB_TYPE_INIT".
97        - Added built-in script constant "$NI_CB_TYPE_NOTE".
98        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
99        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
100        - NKSP Language: Added support for user defined script functions.

110        - removed empty directories left from the cvs to svn migration
111        - fixed compilation with gcc 4.6.1
112        - another "make dist" fix, for the LV2 plugin
113        - made --enable-pthread-testcancel default on Mac OS X
114        - minor Makefile fix for building lscpparser when build and source
115          directories are separate
116        - Mac OS X: made it possible to specify plugin installation dir to

136        - support building with older jack versions
137        - support building with spaces in vst sdk path
138        - enabled automake 'subdir-objects' option and moved external
139          source references (vst, au, asio) from makefiles to cpp files,
140          in order to get rid of warnings from automake 1.14
141    
142      * general changes:
143        - Refactoring: moved the independent code from
144          the Gigasampler format engine to base classes
145        - command line option '--profile' is currently disabled, since the
146          respective profiling code is currently broken
147        - Introduced support for optional environment variable
148          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
149          where the sampler shall look for instrument editor plugins
150          (patch by Luis Garrido, slightly modified).
151        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
152        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
153        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
154          note (in this implementation of the sampler its simply hard routed to
155          the 1st effect send of the sampler channel, no matter what the actual
156          effect type is)
157        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
158          note (in this implementation of the sampler its simply hard routed to
159          the 2nd effect send of the sampler channel, no matter what the actual
160          effect type is)
161        - implemented support for internal LADSPA effects
162        - raised limit of program change queue from 100 to 512
163          (as suggested by Alex Stone)
164        - implemented sine LFO, pulse LFO and saw LFO
165        - experimental support for per voice equalization
166        - added command line option --exec-after-init
167        - Introduced new C++ API method:
168          EngineChannel::InstrumentFileName(int index)
169          allowing to retrieve the whole list of files used for the loaded
170          instrument on an engine channel (a.k.a. part). Some GigaStudio
171          instruments for example are splitted over several files like
172          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
173        - Added new C++ API method Sampler::GetGlobalMaxVoices().
174        - Added new C++ API method Sampler::GetGlobalMaxStreams().
175        - Added new C++ API method Sampler::SetGlobalMaxVoices().
176        - Added new C++ API method Sampler::SetGlobalMaxStreams().
177        - Various "const" and "restrict" optimizations.
178        - all engines: add pan CC value to instrument pan parameter before
179          applying panning, instead of using two separate pan functions in
180          series (#182)
181        - added a lock guard class for exception safe mutex handling and
182          used it everywhere appropriate
183        - Immediately apply scale tuning changes to active voices.
184        - Exposed scale tuning to C++ API (along to the already existing standard
185          SysEx way).
186        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
187          and broken for ppc64. (Seq_cst loads and stores are actually not
188          used in LS, so the bug wasn't noticable.)
189        - lsatomic.h: added ARMv7 support
190        - Added support for multiple MIDI input ports per sampler channel (and
191          added various new C++ methods for this new feature / design change, old
192          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
193          as deprecated but are still there and should provide full behavior
194          backward compatibility).
195        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
196          unsafe and caused compilation error with clang 2.x).
197        - Bugfix: only process the latest MIDI program change event.
198        - Introducing the LSCP shell, which provides convenient control of the
199          sampler from the command line by providing LSCP aware features.
200        - VirtualMidiDevice: Added support for program change.
201        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
202        - VirtualMidiDevice: Added support for pitch bend.
203        - Aftertouch: extended API to explicitly handle channel pressure and
204          polyphonic key pressure events (so far polyphonic pressure was not
205          supported at all, and channel pressure was rerouted as CC128 but not
206          used so far).
207        - Added initial support for real-time instrument scripts. The script VM
208          code is shared by all sampler engine implemementations, however only the
209          gig file format currently provides support for storing instrument scripts
210          (as LinuxSampler extension to the original GigaStudio 4 format).
211    
212      * Gigasampler format engine:
213        - implemented the "round robin keyboard" dimension
214        - fixed round robin and random dimensions for cases when number of
215          dimension zones is not a power of two
216        - made round robin use a counter for each region instead of each
217          key
218        - bugfix: pitch LFO controller "internal+aftertouch" was broken
219        - bugfix: filter keyboard tracking was broken
220        - filter performance fix (an unnecessary copy was made of the
221          filter parameters in each sub fragment)
222        - handle special case when pan parameter in gig file has max or
223          min value
224        - Exclusive Groups: don't ever stop voices of the same note,
225          doesn't sound naturally with a drumkit
226        - fixed EG1 modulation when attack or release is zero
227        - Fixed support for 'aftertouch' attenuation controller.
228        - Fixed crash that happened with velocity split sounds under certain
229          conditions (see also previous commit on libgig).

250        - fine-tuned the default velocity curve
251        - added support for transpose
252        - fixed crash when using sw_down/up
253        - improved logic for sw_lokey/hikey/up/down/last
254        - added more v1 aliases to parser
255        - reduced memory usage for sfz data
256        - RT-safeness: avoid malloc in audio thread
257        - fixed a bug that could cause voice stealing to fail

379          used
380        - bugfix: looping was disabled if loop_start was set to 0
381        - allow regions with end=-1 to turn off other regions using the

407        - AU bugfix: failed to destroy its audio/MIDI devices
408        - Listen to all interfaces on Mac OS X (INADDR_ANY)
409        - VST bugfix: If the host called resume() before and after
410          changing sample rate or block size, the number of channels was
411          incorrectly set to two. This caused silence in Cubase 5.
412        - save engine type (gig, sfz or sf2) in plugin state
413        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
414          64 bit Windows
415        - AU: changed number of output channels from one stereo to 16
416          stereo

426        - thread safety fixes for the instrument loading thread
427        - LV2: use the new lv2 package if present
428        - VST: try to open Fantasia automatically on Linux and Mac too (on
429          Linux, the Fantasia jar should be placed in <prefix>/share/java)
430        - VST: fixed crashes on Linux Ardour and EnergyXT
431        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

444        - Changed instrument editor plugin interface, providing additional
445          informations like the EngineChannel for which the instrument editor was
446          spawned for. This allows the instrument editors to interact more actively
447          with the sampler.
448    
449      * MIDI driver:
450        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
451          the ALSA sequencer client name

453          there is no reason for this limit
454        - MME: fixed memory handling bug found with cppcheck
455        - MME: removed compiler warning
456        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
457          which allows to retrieve the list of CoreMIDI clients / ports and to connect
458          to them a la JACK, via the usual sampler APIs
459        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
460          the driver will automatically connect to other CoreMIDI clients' ports

465          virtual keyboards in frontends / instrument editors being stuck.
466        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
467        - Implemented missing handling of MIDI "running status".
468        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
469        - MME bugfix: driver wasn't closed properly
470        - CoreMIDI: automatically connect to all input sources by default (driver
471          parameter "AUTO_BIND").
472        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
473        - CoreMIDI: fixed minor memory leak
474    
475      * audio driver:
476        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
477        - JACK audio: react on sample rate changes.
478        - JACK audio: react on buffer size changes.

480          RT context.
481        - ASIO driver: removed compiler warnings
482        - CoreAudio: fixed minor error handling bug
483        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
484        - JACK audio: return the JACK server's current sample rate as default value
485          for audio device parameter "SAMPLERATE" (fixes #166).
486

534        - Added support for moving cursor left/right with arrow keys.
535        - Added support for built-in LSCP reference documentation, which will
536          automatically show the relevant LSCP reference section on screen as soon
537          as one specific LSCP command was detected while typing on the command
538          line.

557        - Implemented built-in script function "set_controller()".
558        - Added extended script VM for the Gigasampler/GigaStudio format sampler
559          engine, which extends the general instrument script VM with Giga format

594        - fixed crash when deleting a sampler channel or changing engine
595          type while an instrument load was in progress
596        - bugfix: playing a note while changing the instrument could cause
597          a crash, or give "Handing back unknown region" error messages
598        - bugfix: calling SET VOICES (which Fantasia does on start and
599          refresh) could cause instruments to be unloaded
600        - Mac OS X: fixed name collision of enum in EffectControl and
601          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
602        - Mac OS X: fixed hanging threads
603        - Windows: disabled the previous thread fix on non-Mac systems, as
604          it caused hanging threads on Windows
605        - Fixed possible crashes due to corrupted MIDI/audio device list
606          after MIDI/audio device creation failure
607        - When creating MIDI instrument map entries with "PERSISTENT" type, the
608          instruments were uselessly precached with zero samples, however it still
609          took the full preloading time and on 1st program change the respective
610          instrument was completely reloaded again.
611        - fixed handling of rapid bank select and program change messages
612          sent to the same sampler channel (patch from the Open Octave
613          project, slightly adjusted)

624        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
625        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
626          introduced in previous fix)
627        - fixed crash when a channel received a program change while
628          playing a note in a key group
629        - fixed erroneous error message piping in VoiceBase.h
630          (labelled "Disk stream not available in time")
631        - Update effects on sample rate & period size changes (to avoid
632          crashes and noise on such transitions).
633        - ignore missing LADSPA paths without ignoring valid LADSPA paths
634          (fixes #208)
635        - Fixed bug in LSCP grammar definition which caused a statement like
636          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
637          practically irrelevant, however it caused problems with the new LSCP
638          shell's auto completion feature).
639        - Fixed MIDI program change messages being ignored if quickly executed
640          after each other (fixes #231).
641    
642    Version 1.0.0 (31 July 2009)
643    
644      * packaging changes:
645        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
646          causing e.g. the libgig test to fail when
647          "./configure --disable-jack-driver" was used
648          (patch by Alexis Ballier)
649        - fixed compilation with gcc 4.3
650        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
651        - fixed configure so it detects x86_64 (#107)
652        - fixes for building with newer MinGW versions
653        - fix for building with bison 2.4 (#111)
654        - fixed building with libgig installed in a non-standard directory
655        - minor fix in configure for mmsystem.h detection on MinGW
656        - Windows: look for editor plugins and Fantasia using base
657          directory of liblinuxsampler dll (look in the same directory and one
658          directory above)
659        - configure script fix: removed unconditional use of SSE
660        - fixed building with sqlite installed in a non-standard directory
661        - when cross-compiling, don't try to create instruments.db
662        - fix for new mingw-w64 version, which has usleep
663    
664      * general changes:
665        - bugfix: on some POSIX systems instrument editor plugins refused to
666          load as we used a non-portable Linux specific struct field
667          (fixes bug #70, patch by Ronald Baljeu)
668        - fixed endless loop which occured when loading an instrument editor
669          plugin DLL on Windows systems failed
670        - fixed memory leaks that occurred when liblinuxsampler was unloaded
671        - optimized the SynchronizedConfig class so it doesn't wait
672          unnecessarily long after an update
673        - added support for notifying instrument editors on note-on / note-off
674          events (e.g. to highlight the pressed keys on the virtual keyboard
675          of gigedit)
676        - added support for triggering notes by instrument editors (see above)
677        - be verbose on DLL load errors (on Linux)
678        - fixed di-harmonic triangle LFO implementation (this LFO implementation
679          is only used by very few systems, most pick the int math
680          implementation, which is usually faster)
681        - fixes for audio drivers with varying buffer sizes
682        - experimental support for running LinuxSampler as a DSSI, LV2 and
683          VST plugin
684        - notification events for stream/voice count statistics are now sent
685          only when there are actual changes
686        - added memory ordering constraints to improve stability on
687          multi-core and multi-cpu systems
688        - maximum voices and disk streams can now be altered at runtime
689        - fixed CPU feature detection on x86_64 (maybe fixes #108)
690        - automatic stacktrace mechanism is now turned off by default and can
691          be switched on by command line option "--stacktrace" (the automatic
692          stacktrace mechanism seems to be broken on most systems at the moment)
693        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
694          a pointer to the launched InstrumentEditor object
695        - added optional 3rd party user data parameter for following
696          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
697          InstrumentEditor::Launch(),
698          InstrumentManager::LaunchInstrumentEditor()
699        - theoretical fix: made SynchronizedConfig follow C++0x memory
700          model more strictly
701        - fixes for using large audio device buffers
702        - Windows: add the installation directory to the DLL search path
703          when loading an editor plugin (solves problems with VST and
704          gigedit on systems with other GTK versions installed)
705        - updated linuxsampler man page
706    
707      * audio driver:
708        - removed the nonsense audio channel constraint (which was hard coded to
709          max. 100 audio channels) for most audio drivers
710        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
711          opposed to the LSCP specs
712        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
713          reflected the wrong value
714        - fixed a memory management bug in ASIO driver
715        - Makefile fix: JACK_CFLAGS wasn't used
716        - JACK: use jack_client_open instead of the deprecated
717          jack_client_new
718        - added (experimental) CoreAudio driver
719        - applied old fixes to the ASIO driver that were included in the
720          previous binary release but accidentally never committed to CVS
721          (fixes #117)
722        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
723          win64)
724        - VST: added support for sample rate and buffer size changes
725        - VST: close editor (Fantasia) when the VST is removed
726        - VST: avoid opening Fantasia more than once for each VST instance
727        - VST: export main function as "main" on Linux too (fix for
728          energyXT)
729        - VST: changed number of output channels from one stereo to 16
730          stereo
731        - added channel routing, fxsends and midi maps to the settings
732          stored in the plugin state
733        - performance optimization of AudioChannel::MixTo() and
734          AudioChannel::CopyTo() methods using GCC vector exensions
735          (if available)
736        - ASIO fixes: avoid initializing the device twice, avoid throwing
737          exception when getting parameters from a disconnected device
738    
739      * MIDI driver:
740        - added JACK MIDI driver
741        - dispatch bank select as ordinary CC as well, the user might seriously
742          want to (mis)use it for some purpose ("fixed" in all current MIDI
743          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
744        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
745          CoreMidi or AU
746        - fixed mingw-w64 compilation error in MME driver
747        - made program change handling in MIDI thread real-time safe by
748          moving the logic to a non-RT thread
749        - fixed minor memory leak in ALSA driver
750    
751      * instruments database:
752        - avoid time consuming samples scanning when adding instruments
753          to the instruments database
754        - added support for handling lost files in the instruments database
755        - Implemented option for adding instruments in separate directories
756          in the instruments database
757          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
758        - work-around for missing fnmatch function on Windows to make
759          instrument database compilable
760        - added instrument database support on Windows
761          works with both standalone mode and VST plugin.
762          the instruments DB file is located in
763          %USERPROFILE%\.linuxsampler\instruments.db which allows different
764          databases for each windows user
765          if no DB is present it automatically creates the .linuxsampler subdir
766          and then creates an empty DB
767        - fixed recursive import, which was broken on Windows
768    
769      * Gigasampler format engine:
770        - fixed a memory leak that could happen when a channel was deleted
771          while notes were playing
772        - made it possible to load an instrument even if the audio thread
773          isn't running
774        - added partial support for the "Controller Triggered" MIDI rule,
775          enough for piano gigs with pedal noise samples
776        - minor fix: only mark FX sends as being modified if really the
777          respective FX send MIDI controller was used
778        - added support for GM global device volume SysEx message
779          (can be selected at compile time to either apply globally to the
780          whole sampler [default] or only to the sampler channels that are
781          connected to the respective MIDI input port the SysEx message arrived
782          on)
783        - bugfix: notes triggered at position 0 in the audio buffer were
784          sometimes wrongly killed in the same buffer, causing no sound to
785          be played
786        - added support for chromatic / drumkit mode Roland GS Sysex message
787          which is usally used to switch a part between chromatic sounds and
788          drumkit sounds (as opposed to their common default setting of MIDI
789          part 10 being a drumkit part and all other ones chromatic parts), in
790          LS however one can switch between the first 16 MIDI instrument maps
791          defined for the sampler
792        - made it possible to create multiple sample channels even if the
793          audio thread isn't running
794        - fixed crash when removing channel with active voices (#116)
795        - bugfix: on sample reference changes (instrument editor), only
796          un-cache the respective sample if it's really not used by any
797          sampler engine anymore
798        - re-cache samples in case they were changed by an instrument editor,
799          e.g. when a sample was added while playing (#82)
800        - fixed hanging notes which occured when note-off event had the exact
801          same time stamp as the voice's note-on event and occured both in the
802          same audio fragment cycle (fixes bug #112)
803        - added support for the "fine tune" and "pitch bend range"
804          instrument-level gig parameters
805        - fixed minor artifacts in pitch bend handling
806        - added support for GS Reset SysEx message
807        - allow gig files to use unlimited downward pitch shifting
808        - added a limit check for upward pitch shifting
809        - bugfix: sometimes, when playing a note twice fast, the second
810          note was silent
811        - fixed crash happening when a pitch bend event arrived at the
812          same time a new instrument was loading
813    
814      * LSCP server:
815        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
816          react on MIDI data arriving on certain sampler channels (so far only
817          Note-On and Note-Off events are sent via this LSCP event)
818        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
819          react on MIDI data arriving on certain MIDI input devices (so far only
820          Note-On and Note-Off events are sent via this LSCP event)
821        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
822          SET DB_INSTRUMENT FILE_PATH
823        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
824          frontends to send MIDI messages to specific sampler channel
825        - added two additional fields to GET FILE INSTRUMENT INFO command -
826          KEY_BINDINGS and KEYSWITCH_BINDINGS
827        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
828          was incorrect
829        - Optimized the retrieval of the MIDI instrument mappings
830        - added new LSCP command "SET VOICES" to globally alter the maximum
831          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
832          be triggered respectively
833        - added new LSCP command "SET STREAMS" to globally alter the maximum
834          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
835          which will be triggered respectively
836        - bugfix: retry if "select" returns EINTR (this fixes a crash when
837          a gigedit file dialog is opened)
838        - close all connections when LSCPServer is deleted
839        - hard close of all sockets on exit
840        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
841          driver
842    
843      * Bug fixes:
844        - fixed a crash which occurs when removing a sampler channel waiting
845          to start instrument loading after another channel
846        - fixed a crash which occurs when removing a sampler channel with
847          instrument loading in progress (bug #113)
848        - fixed termination caused by uncaught exception when adding MIDI
849          instrument with PERSISTENT load mode
850        - fixed possible iterator invalidations when resetting the sampler
851        - fixed memory leaks when issuing the following LSCP commands:
852          GET AUDIO_OUTPUT_DRIVER INFO
853          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
854          GET MIDI_INPUT_DRIVER INFO
855          GET MIDI_INPUT_DRIVER_PARAMETER INFO
856        - fixed possible compilation error when sqlite is not present
857        - fixed orphaned pointers when setting maximum voices limit (bug #118)
858        - fixed crash when changing the audio output device of a sampler
859          channel with loaded instrument and start playing notes
860        - fixed endless loop in Engine::SuspendAll() (bug #120)
861        - fixed a low-level atomic load function that was broken on 64-bit
862          PowerPC, which probably could cause crashes on that platform
863        - fixed a memory management error which could cause a crash when a
864          plugin was unloaded
865        - bugfix: two private structs had the same name, which could cause
866          problems if the linker chose the wrong constructor
867        - fixed low-level ConditionServer usage bug that caused lockups on
868          Windows
869    
870    
871    Version 0.5.1 (6 December 2007)
872    
873      * packaging changes:
874        - added autoconf checks for pthread library
875        - added autoconf check for pthread bug found on certain NPTL-enabled
876          glibc versions (see Gentoo bug report #194076)
877        - added autoconf checks for MS Windows
878    
879      * general changes:
880        - bugfix: the thread used by an editor plugin didn't die when the
881          editor closed
882        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
883          out all the space. operator--() did not apply size_mask after
884          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
885          order to avoid problems with the _NonVolatileReader functions.
886        - bugfix: Stream.h: added a missing divide by BytesPerSample in
887          GetWriteSpace(). Since this function is currently only used in
888          the stream's qsort() compare function, it didn't trigger any
889          bugs.
890        - Resampler.h, Synthesizer.h: cubic interpolation now works in
891          24bit mode too. Faster method to read 24bit words on little
892          endian machines (x86): replaced 3 byte reads + shifts with a 1
893          unaligned 32bit read and shift
894        - experimental support for MS Windows (MIDI input via MME, AUDIO
895          output via ASIO)
896        - made handling of SIGINT signal (Ctrl-C) a bit more robust
897        - support for monitoring the total number of active disk streams
898          (new LSCP commands: GET TOTAL_STREAM_COUNT,
899          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
900    
901      * AUDIO driver:
902        - added Windows ASIO low latency audio driver
903    
904      * MIDI driver:
905        - added MME Windows MIDI driver
906    
907      * LSCP server:
908        - added support for Windows style path / filenames, however with
909          forward slash path separators instead of backslash
910          (i.e. "C:/foo/bar.gig")
911        - allow naughty liblscp to send non-string device parameters within
912          apostrophes as well
913        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
914          "LIST FILE INSTRUMENTS <file>" and
915          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
916          about an arbitrary instrument file on the system where the sampler is
917          running on
918    
919    Version 0.5.0 (15 October 2007)
920    
921    * packaging changes:    * packaging changes:
922        - config.h is not going to be installed along with liblinuxsampler's
923          API header files anymore
924        - only the API relevant header (and source) files will be exported to
925          the Doxygen API documentation (explicitly listed in Doxyfile.in)
926        - added completely new XCode project files for Mac OSX which is now
927          capable to execute our autoconf environment, thus no need anymore
928          to maintain the compile time configuration file (osx/version.h) for
929          OSX manually (patch by Toshi Nagata)
930        - fixed buggy boolean --enable-foo / --disable-foo configure script
931          parameters
932        - global.h now only covers global definitions that are needed for the
933          C++ API header files, all implementation internal global definitions
934          are now in global_private.h
935        - atomic.h is not exposed to the C++ API anymore
936        - no need to include config.h anymore for using LS's API header files
937        - fixed warnings in API doc generation
938    
939      * general changes:
940        - replaced the old, confusing MIDI program change mechanism by a
941          flexible MIDI instrument mapper which allows to map arbitrary
942          (MIDI bank, MIDI program) pairs with arbitrary
943          (engine type, instrument file, file index) triplets which will be
944          loaded on the respective channel when such MIDI program change
945          messages arrive, beside that, each entry allows to define a life-time
946          strategy for the instrument, so the user can define whether the
947          instrument should i.e. be permanently loaded (to be able to switch
948          quickly among sounds) or i.e. loaded just on demand when the
949          respective program change arrives (to safe RAM space), as well as a
950          global volume factor for each entry, so the user can adjust the volume
951          dynamic of his mapped instrument collection without having to modify
952          the instrument files, also one can manage arbitrary amount of such
953          MIDI instrument maps and assign each sampler channel individually
954          a certain map, so that i.e. separation of normal instruments and
955          drumkits is possible
956        - new notification events for tracking changes to audio/MIDI devices,
957          MIDI instrument maps, MIDI instruments, FX sends, global volume.
958        - sampler was limited to load max. 200 instruments in the background
959          due to a constant size RingBuffer FIFO which is now replaced by a
960          dynamic (unlimited) size std::list FIFO
961        - added FX sends, these allow to route audio signals to arbitrary audio
962          output channels for being processed by external effect processors
963          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
964          controllers
965        - global (sampler wide) volume can now be controlled at runtime
966        - Implemented new, improved notification system
967        - fixed compilation errors regarding OSX
968          (patch by Toshi Nagata)
969        - implemented instruments database
970        - added support for escape sequences to the instruments database
971        - added highly experimental support for on-the-fly instrument editing
972          within the sampler's process (by using instrument editor plugins),
973          you'll notice the new "Registered instrument editors:" message on
974          startup, added a new LSCP command:
975          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
976          to spawn a matching instrument editor for the instrument on the
977          given sampler channel, the plugin path can be overridden at compile
978          time with ./configure --enable-plugin-dir=/some/dir
979        - added experimental code for synchronizing instrument editors hosted
980          in the sampler's process to safely edit instruments while playing
981          without a crash (hopefully) by either suspending single regions
982          wherever possible or if unavoidable whole engine(s)
983        - fixed several issues in fundamental "Thread" class: set scheduling
984          policy and priority on thread level, set a minimum stack size for
985          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
986          threads simply inherited properties of starting thread instead of
987          setting their own policy and priority
988        - minor fix in our automatic stack trace mechanism on crashes, the
989          main process did not wait for the stack trace process to finish
990          its output
991        - fixed some minor memory leaks
992        - reenabled assembly features support, at the moment only for
993          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
994        - minor assembly fix in x86 features detection (don't use the PIC
995          register, to avoid relocations in the text segment at runtime)
996        - POSIX callback functions of Thread.h are hidden
997    
998      * MIDI driver:
999        - dispatch bank select (MSB and LSB) messages
1000    
1001      * audio driver:
1002        - the ALSA audio output driver parameters now reflect the correct
1003          parameter value ranges for the respective selected sound card
1004          (patch by Till Wimmer, a bit fixed and extended)
1005    
1006      * Gigasampler format engine:
1007        - if a filter is used and EG2 finishes before EG1, let the voice
1008          die when EG2 has finished (this fixes a problem with clicks and
1009          voice starvation for some gigs)
1010        - playback is no longer disabled during instrument loading
1011        - all notes playing on a channel that changes its instrument keep
1012          playing with the old instrument until they get a note off
1013          command
1014        - EG fix: a release value of zero could cause noises or crash
1015        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1016        - EG fine tuning: when attack is zero the EG starts at a level
1017          above max sustain level, which means that there is a decay phase
1018          even if sustain is 100%
1019        - more EG fixes: the level could sometimes go below zero and cause
1020          noises or crashes
1021        - minor fix of EGDecay (patch by Toshi Nagata)
1022        - fixed compiler error when --enable-override-filter-type was
1023          supplied to the configure script (fixes #46)
1024        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1025          instead of a fix value
1026        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1027          127 (solo mode) only kill voices if the respective mode really
1028          changed
1029    
1030      * LSCP server:
1031        - fixed compile time error for old Bison versions
1032          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1033        - parser now supports extended ASCII character set
1034          (up to ASCII code 255, i.e. includes now umlauts and accents)
1035        - filename arguments in LSCP commands now allow to use escape
1036          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1037          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1038          code value like \xf2) (fixes bug #24)
1039        - the following LSCP commands now also support escape sequences for at
1040          least one of their text-based parameters (i.e. name, description):
1041          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1042          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1043          "SET DB_INSTRUMENT_DIRECTORY NAME",
1044          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1045          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1046          "FIND DB_INSTRUMENT_DIRECTORIES"
1047        - returns verbose syntax errors (line and column where syntax error
1048          occured, the unexpected character and the actually expected, possible
1049          character(s), the latter only if less than 5 possibilities)
1050        - made sure that LSCP syntax is not affected by gigedit locale
1051          settings
1052        - bugfix regarding strings parameter lists: all comma separated lists
1053          of strings were treated as being one string containing commas
1054          (fixes #57)
1055    
1056      * Bug fixes:
1057        - fixed crash occurring on certain LSCP scripts (Bug 39)
1058        - another thread safety fix for lscp "load engine" and "set
1059          channel audio output device"
1060        - fixed a crash which occurs when reassigning the same engine
1061          on a sampler channel with connected MIDI device
1062        - fixed a crash which occurs when changing the number of ports of a MIDI
1063          device connected to a sampler channel to number less then or equal
1064          to the index of the port to which the sampler channel is connected.
1065        - The previous bindings were not been disconnected when altering
1066          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1067          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1068        - The active stream/voice count statistic was incorrect.
1069        - notification events were not been sent for some sampler
1070          channel changes
1071        - added default min and max values to restrict the number of allowed
1072          audio output channels and MIDI input ports
1073        - the connection to the PCM interface is now closed when destroying
1074          an audio output device
1075        - files with slash in their path or filename could not be loaded
1076    
1077      * test cases:
1078        - updated and fixed (haven't been touched in a while)
1079    
1080    Version 0.4.0 (24 November 2006)
1081    
1082      * packaging changes:
1083        - changed deprecated copyright attribute to license; added ldconfig
