# 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    
89    Version 2.0.0 (15 July 2015)

93        - Mac OS X: support the new dir for Core Audio SDK
94        - Mac OS X: fixed building outside source directory
95        - made sure all source files for hostplugins are included when

97        - removed empty directories left from the cvs to svn migration
98        - fixed compilation with gcc 4.6.1
99        - another "make dist" fix, for the LV2 plugin
100        - made --enable-pthread-testcancel default on Mac OS X
101        - minor Makefile fix for building lscpparser when build and source
102          directories are separate
103        - Mac OS X: made it possible to specify plugin installation dir to
104          configure
105        - Mac OS X: Makefile fix for the install-strip target
106        - fixed compilation with gcc 4.7

120        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
121          on the process's main thread
122        - fixed build error on newer MinGW
123        - support building with older jack versions
124        - support building with spaces in vst sdk path
125        - enabled automake 'subdir-objects' option and moved external
126          source references (vst, au, asio) from makefiles to cpp files,
127          in order to get rid of warnings from automake 1.14
128    
129      * general changes:
130        - Refactoring: moved the independent code from
131          the Gigasampler format engine to base classes
132        - command line option '--profile' is currently disabled, since the
133          respective profiling code is currently broken
134        - Introduced support for optional environment variable
135          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
136          where the sampler shall look for instrument editor plugins
137          (patch by Luis Garrido, slightly modified).
138        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
139        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
140        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
141          note (in this implementation of the sampler its simply hard routed to
142          the 1st effect send of the sampler channel, no matter what the actual
143          effect type is)
144        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
145          note (in this implementation of the sampler its simply hard routed to
146          the 2nd effect send of the sampler channel, no matter what the actual
147          effect type is)
148        - implemented support for internal LADSPA effects
149        - raised limit of program change queue from 100 to 512
150          (as suggested by Alex Stone)
151        - implemented sine LFO, pulse LFO and saw LFO
152        - experimental support for per voice equalization
153        - added command line option --exec-after-init
154        - Introduced new C++ API method:
155          EngineChannel::InstrumentFileName(int index)
156          allowing to retrieve the whole list of files used for the loaded
157          instrument on an engine channel (a.k.a. part). Some GigaStudio
158          instruments for example are splitted over several files like
159          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
160        - Added new C++ API method Sampler::GetGlobalMaxVoices().
161        - Added new C++ API method Sampler::GetGlobalMaxStreams().
162        - Added new C++ API method Sampler::SetGlobalMaxVoices().
163        - Added new C++ API method Sampler::SetGlobalMaxStreams().
164        - Various "const" and "restrict" optimizations.
165        - all engines: add pan CC value to instrument pan parameter before
166          applying panning, instead of using two separate pan functions in
167          series (#182)
168        - added a lock guard class for exception safe mutex handling and
169          used it everywhere appropriate
170        - Immediately apply scale tuning changes to active voices.
171        - Exposed scale tuning to C++ API (along to the already existing standard
172          SysEx way).
173        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
174          and broken for ppc64. (Seq_cst loads and stores are actually not
175          used in LS, so the bug wasn't noticable.)
176        - lsatomic.h: added ARMv7 support
177        - Added support for multiple MIDI input ports per sampler channel (and
178          added various new C++ methods for this new feature / design change, old
179          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
180          as deprecated but are still there and should provide full behavior
181          backward compatibility).
182        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
183          unsafe and caused compilation error with clang 2.x).
184        - Bugfix: only process the latest MIDI program change event.
185        - Introducing the LSCP shell, which provides convenient control of the
186          sampler from the command line by providing LSCP aware features.
187        - VirtualMidiDevice: Added support for program change.
188        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
189        - VirtualMidiDevice: Added support for pitch bend.
190        - Aftertouch: extended API to explicitly handle channel pressure and
191          polyphonic key pressure events (so far polyphonic pressure was not
192          supported at all, and channel pressure was rerouted as CC128 but not
193          used so far).
194        - Added initial support for real-time instrument scripts. The script VM
195          code is shared by all sampler engine implemementations, however only the
196          gig file format currently provides support for storing instrument scripts
197          (as LinuxSampler extension to the original GigaStudio 4 format).
198    
199      * Gigasampler format engine:
200        - implemented the "round robin keyboard" dimension
201        - fixed round robin and random dimensions for cases when number of
202          dimension zones is not a power of two
203        - made round robin use a counter for each region instead of each
204          key
205        - bugfix: pitch LFO controller "internal+aftertouch" was broken
206        - bugfix: filter keyboard tracking was broken
207        - filter performance fix (an unnecessary copy was made of the
208          filter parameters in each sub fragment)
209        - handle special case when pan parameter in gig file has max or
210          min value
211        - Exclusive Groups: don't ever stop voices of the same note,
212          doesn't sound naturally with a drumkit
213        - fixed EG1 modulation when attack or release is zero
214        - Fixed support for 'aftertouch' attenuation controller.
215        - Fixed crash that happened with velocity split sounds under certain
216          conditions (see also previous commit on libgig).
217        - fixed behaviour of filter LFO

219      * SFZ format engine:
220        - Initial implementation (not usable yet)

222        - added a fine-tuned v1 envelope generator instead of using the
223          one from the gig engine

225        - added support for trigger=first, trigger=legato and sw_previous
226        - allow non-numerical key values ("C#4" for example)
227        - "key" opcode now sets pitch_keycenter too
228        - fixed error when unloading instrument with same sample used by
229          multiple regions

234        - added support for random, seq_position, seq_length and volume
235        - added v1 LFO opcodes to parser (no support in engine yet)
236        - added support for amp_veltrack and amp_velcurve_N
237        - fine-tuned the default velocity curve
238        - added support for transpose
239        - fixed crash when using sw_down/up
240        - improved logic for sw_lokey/hikey/up/down/last
241        - added more v1 aliases to parser
242        - reduced memory usage for sfz data
243        - RT-safeness: avoid malloc in audio thread
244        - fixed a bug that could cause voice stealing to fail

365        - bugfix: only the first amp_veltrack definition in a file was
366          used
367        - bugfix: looping was disabled if loop_start was set to 0
368        - allow regions with end=-1 to turn off other regions using the
369          group and off_by opcodes (#168)

378          (modified patch which was originally posted by Sergey on LS mailing list)
379        - bugfix: generation of velocity curves etc should not be done
380          after each "#include", only after the main file is parsed
381        - bugfix: line numbers in error messages were wrong after "#include"
382        - added support for float and 32 bit sample files
383    
384      * SoundFont format engine:

394        - AU bugfix: failed to destroy its audio/MIDI devices
395        - Listen to all interfaces on Mac OS X (INADDR_ANY)
396        - VST bugfix: If the host called resume() before and after
397          changing sample rate or block size, the number of channels was
398          incorrectly set to two. This caused silence in Cubase 5.
399        - save engine type (gig, sfz or sf2) in plugin state
400        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
401          64 bit Windows
402        - AU: changed number of output channels from one stereo to 16
403          stereo

412          similar fix was for Windows)
413        - thread safety fixes for the instrument loading thread
414        - LV2: use the new lv2 package if present
415        - VST: try to open Fantasia automatically on Linux and Mac too (on
416          Linux, the Fantasia jar should be placed in <prefix>/share/java)
417        - VST: fixed crashes on Linux Ardour and EnergyXT
418        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
419          port and audio channel routing for DSSI plugins are now visible.
420        - LV2: use urid and atom extensions instead of deprecated uri-map
421          and event
422        - LV2: lv2 package 1.0 is now required to build the LV2 plugin

428          sampler's internal MIDI instrument mapping system
429    
430      * Instrument editor interface:
431        - Changed instrument editor plugin interface, providing additional
432          informations like the EngineChannel for which the instrument editor was
433          spawned for. This allows the instrument editors to interact more actively
434          with the sampler.
435    
436      * MIDI driver:
437        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
438          the ALSA sequencer client name
439        - removed limit of maximum amount of MIDI ports per MIDI device, since
440          there is no reason for this limit
441        - MME: fixed memory handling bug found with cppcheck
442        - MME: removed compiler warning
443        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
444          which allows to retrieve the list of CoreMIDI clients / ports and to connect
445          to them a la JACK, via the usual sampler APIs
446        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
447          the driver will automatically connect to other CoreMIDI clients' ports
448          (e.g. external MIDI devices being attached to the Mac)
449        - added support for MIDI note on velocity filter
450        - CoreMIDI: fixed memory deallocation error
451        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
452          virtual keyboards in frontends / instrument editors being stuck.
453        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
454        - Implemented missing handling of MIDI "running status".
455        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
456        - MME bugfix: driver wasn't closed properly
457        - CoreMIDI: automatically connect to all input sources by default (driver
458          parameter "AUTO_BIND").
459        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
460        - CoreMIDI: fixed minor memory leak
461    
462      * audio driver:
463        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
464        - JACK audio: react on sample rate changes.
465        - JACK audio: react on buffer size changes.

467          RT context.
468        - ASIO driver: removed compiler warnings
469        - CoreAudio: fixed minor error handling bug
470        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
471        - JACK audio: return the JACK server's current sample rate as default value
472          for audio device parameter "SAMPLERATE" (fixes #166).
473    
474      * LSCP server:
475        - added support for sending MIDI CC messages via LSCP command

509          "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
510        - provide comprehensive error messages on LSCP syntax errors
511          (suggesting expected next non-terminal symbols)

521        - Added support for moving cursor left/right with arrow keys.
522        - Added support for built-in LSCP reference documentation, which will
523          automatically show the relevant LSCP reference section on screen as soon
524          as one specific LSCP command was detected while typing on the command
525          line.
526

543          or no argument).
544        - Implemented built-in script function "set_controller()".
545        - Added extended script VM for the Gigasampler/GigaStudio format sampler
546          engine, which extends the general instrument script VM with Giga format
547          specific variables and functions.
548        - Giga format scripts: added built-in script int constant variables
549          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

580          channel to a different engine type
581        - fixed crash when deleting a sampler channel or changing engine
582          type while an instrument load was in progress
583        - bugfix: playing a note while changing the instrument could cause
584          a crash, or give "Handing back unknown region" error messages
585        - bugfix: calling SET VOICES (which Fantasia does on start and
586          refresh) could cause instruments to be unloaded
587        - Mac OS X: fixed name collision of enum in EffectControl and
588          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
589        - Mac OS X: fixed hanging threads
590        - Windows: disabled the previous thread fix on non-Mac systems, as
591          it caused hanging threads on Windows
592        - Fixed possible crashes due to corrupted MIDI/audio device list
593          after MIDI/audio device creation failure
594        - When creating MIDI instrument map entries with "PERSISTENT" type, the
595          instruments were uselessly precached with zero samples, however it still
596          took the full preloading time and on 1st program change the respective
597          instrument was completely reloaded again.
598        - fixed handling of rapid bank select and program change messages
599          sent to the same sampler channel (patch from the Open Octave
600          project, slightly adjusted)
601        - fixed crash when trying to create an effect instance with controls
602          which min and/or max values depend on the sample rate

610        - sfz/sf2 engine: fixed crash when using small audio fragment size
611        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
612        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
613          introduced in previous fix)
614        - fixed crash when a channel received a program change while
615          playing a note in a key group
616        - fixed erroneous error message piping in VoiceBase.h
617          (labelled "Disk stream not available in time")
618        - Update effects on sample rate & period size changes (to avoid
619          crashes and noise on such transitions).
620        - ignore missing LADSPA paths without ignoring valid LADSPA paths
621          (fixes #208)
622        - Fixed bug in LSCP grammar definition which caused a statement like
623          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
624          practically irrelevant, however it caused problems with the new LSCP
625          shell's auto completion feature).
626        - Fixed MIDI program change messages being ignored if quickly executed
627          after each other (fixes #231).
628    
629    Version 1.0.0 (31 July 2009)
630    
631      * packaging changes:
632        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
633          causing e.g. the libgig test to fail when
634          "./configure --disable-jack-driver" was used
635          (patch by Alexis Ballier)
636        - fixed compilation with gcc 4.3
637        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
638        - fixed configure so it detects x86_64 (#107)
639        - fixes for building with newer MinGW versions
640        - fix for building with bison 2.4 (#111)
641        - fixed building with libgig installed in a non-standard directory
642        - minor fix in configure for mmsystem.h detection on MinGW
643        - Windows: look for editor plugins and Fantasia using base
644          directory of liblinuxsampler dll (look in the same directory and one
645          directory above)
646        - configure script fix: removed unconditional use of SSE
647        - fixed building with sqlite installed in a non-standard directory
648        - when cross-compiling, don't try to create instruments.db
649        - fix for new mingw-w64 version, which has usleep
650    
651      * general changes:
652        - bugfix: on some POSIX systems instrument editor plugins refused to
653          load as we used a non-portable Linux specific struct field
654          (fixes bug #70, patch by Ronald Baljeu)
655        - fixed endless loop which occured when loading an instrument editor
656          plugin DLL on Windows systems failed
657        - fixed memory leaks that occurred when liblinuxsampler was unloaded
658        - optimized the SynchronizedConfig class so it doesn't wait
659          unnecessarily long after an update
660        - added support for notifying instrument editors on note-on / note-off
661          events (e.g. to highlight the pressed keys on the virtual keyboard
662          of gigedit)
663        - added support for triggering notes by instrument editors (see above)
664        - be verbose on DLL load errors (on Linux)
665        - fixed di-harmonic triangle LFO implementation (this LFO implementation
666          is only used by very few systems, most pick the int math
667          implementation, which is usually faster)
668        - fixes for audio drivers with varying buffer sizes
669        - experimental support for running LinuxSampler as a DSSI, LV2 and
670          VST plugin
671        - notification events for stream/voice count statistics are now sent
672          only when there are actual changes
673        - added memory ordering constraints to improve stability on
674          multi-core and multi-cpu systems
675        - maximum voices and disk streams can now be altered at runtime
676        - fixed CPU feature detection on x86_64 (maybe fixes #108)
677        - automatic stacktrace mechanism is now turned off by default and can
678          be switched on by command line option "--stacktrace" (the automatic
679          stacktrace mechanism seems to be broken on most systems at the moment)
680        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
681          a pointer to the launched InstrumentEditor object
682        - added optional 3rd party user data parameter for following
683          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
684          InstrumentEditor::Launch(),
685          InstrumentManager::LaunchInstrumentEditor()
686        - theoretical fix: made SynchronizedConfig follow C++0x memory
687          model more strictly
688        - fixes for using large audio device buffers
689        - Windows: add the installation directory to the DLL search path
690          when loading an editor plugin (solves problems with VST and
691          gigedit on systems with other GTK versions installed)
692        - updated linuxsampler man page
693    
694      * audio driver:
695        - removed the nonsense audio channel constraint (which was hard coded to
696          max. 100 audio channels) for most audio drivers
697        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
698          opposed to the LSCP specs
699        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
700          reflected the wrong value
701        - fixed a memory management bug in ASIO driver
702        - Makefile fix: JACK_CFLAGS wasn't used
703        - JACK: use jack_client_open instead of the deprecated
704          jack_client_new
705        - added (experimental) CoreAudio driver
706        - applied old fixes to the ASIO driver that were included in the
707          previous binary release but accidentally never committed to CVS
708          (fixes #117)
709        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
710          win64)
711        - VST: added support for sample rate and buffer size changes
712        - VST: close editor (Fantasia) when the VST is removed
713        - VST: avoid opening Fantasia more than once for each VST instance
714        - VST: export main function as "main" on Linux too (fix for
715          energyXT)
716        - VST: changed number of output channels from one stereo to 16
717          stereo
718        - added channel routing, fxsends and midi maps to the settings
719          stored in the plugin state
720        - performance optimization of AudioChannel::MixTo() and
721          AudioChannel::CopyTo() methods using GCC vector exensions
722          (if available)
723        - ASIO fixes: avoid initializing the device twice, avoid throwing
724          exception when getting parameters from a disconnected device
725    
726      * MIDI driver:
727        - added JACK MIDI driver
728        - dispatch bank select as ordinary CC as well, the user might seriously
729          want to (mis)use it for some purpose ("fixed" in all current MIDI
730          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
731        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
732          CoreMidi or AU
733        - fixed mingw-w64 compilation error in MME driver
734        - made program change handling in MIDI thread real-time safe by
735          moving the logic to a non-RT thread
736        - fixed minor memory leak in ALSA driver
737    
738      * instruments database:
739        - avoid time consuming samples scanning when adding instruments
740          to the instruments database
741        - added support for handling lost files in the instruments database
742        - Implemented option for adding instruments in separate directories
743          in the instruments database
744          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
745        - work-around for missing fnmatch function on Windows to make
746          instrument database compilable
747        - added instrument database support on Windows
748          works with both standalone mode and VST plugin.
749          the instruments DB file is located in
750          %USERPROFILE%\.linuxsampler\instruments.db which allows different
751          databases for each windows user
752          if no DB is present it automatically creates the .linuxsampler subdir
753          and then creates an empty DB
754        - fixed recursive import, which was broken on Windows
755    
756      * Gigasampler format engine:
757        - fixed a memory leak that could happen when a channel was deleted
758          while notes were playing
759        - made it possible to load an instrument even if the audio thread
760          isn't running
761        - added partial support for the "Controller Triggered" MIDI rule,
762          enough for piano gigs with pedal noise samples
763        - minor fix: only mark FX sends as being modified if really the
764          respective FX send MIDI controller was used
765        - added support for GM global device volume SysEx message
766          (can be selected at compile time to either apply globally to the
767          whole sampler [default] or only to the sampler channels that are
768          connected to the respective MIDI input port the SysEx message arrived
769          on)
770        - bugfix: notes triggered at position 0 in the audio buffer were
771          sometimes wrongly killed in the same buffer, causing no sound to
772          be played
773        - added support for chromatic / drumkit mode Roland GS Sysex message
774          which is usally used to switch a part between chromatic sounds and
775          drumkit sounds (as opposed to their common default setting of MIDI
776          part 10 being a drumkit part and all other ones chromatic parts), in
777          LS however one can switch between the first 16 MIDI instrument maps
778          defined for the sampler
779        - made it possible to create multiple sample channels even if the
780          audio thread isn't running
781        - fixed crash when removing channel with active voices (#116)
782        - bugfix: on sample reference changes (instrument editor), only
783          un-cache the respective sample if it's really not used by any
784          sampler engine anymore
785        - re-cache samples in case they were changed by an instrument editor,
786          e.g. when a sample was added while playing (#82)
787        - fixed hanging notes which occured when note-off event had the exact
788          same time stamp as the voice's note-on event and occured both in the
789          same audio fragment cycle (fixes bug #112)
790        - added support for the "fine tune" and "pitch bend range"
791          instrument-level gig parameters
792        - fixed minor artifacts in pitch bend handling
793        - added support for GS Reset SysEx message
794        - allow gig files to use unlimited downward pitch shifting
795        - added a limit check for upward pitch shifting
796        - bugfix: sometimes, when playing a note twice fast, the second
797          note was silent
798        - fixed crash happening when a pitch bend event arrived at the
799          same time a new instrument was loading
800    
801      * LSCP server:
802        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
803          react on MIDI data arriving on certain sampler channels (so far only
804          Note-On and Note-Off events are sent via this LSCP event)
805        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
806          react on MIDI data arriving on certain MIDI input devices (so far only
807          Note-On and Note-Off events are sent via this LSCP event)
808        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
809          SET DB_INSTRUMENT FILE_PATH
810        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
811          frontends to send MIDI messages to specific sampler channel
812        - added two additional fields to GET FILE INSTRUMENT INFO command -
813          KEY_BINDINGS and KEYSWITCH_BINDINGS
814        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
815          was incorrect
816        - Optimized the retrieval of the MIDI instrument mappings
817        - added new LSCP command "SET VOICES" to globally alter the maximum
818          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
819          be triggered respectively
820        - added new LSCP command "SET STREAMS" to globally alter the maximum
821          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
822          which will be triggered respectively
823        - bugfix: retry if "select" returns EINTR (this fixes a crash when
824          a gigedit file dialog is opened)
825        - close all connections when LSCPServer is deleted
826        - hard close of all sockets on exit
827        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
828          driver
829    
830      * Bug fixes:
831        - fixed a crash which occurs when removing a sampler channel waiting
832          to start instrument loading after another channel
833        - fixed a crash which occurs when removing a sampler channel with
834          instrument loading in progress (bug #113)
835        - fixed termination caused by uncaught exception when adding MIDI
836          instrument with PERSISTENT load mode
837        - fixed possible iterator invalidations when resetting the sampler
838        - fixed memory leaks when issuing the following LSCP commands:
839          GET AUDIO_OUTPUT_DRIVER INFO
840          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
841          GET MIDI_INPUT_DRIVER INFO
842          GET MIDI_INPUT_DRIVER_PARAMETER INFO
843        - fixed possible compilation error when sqlite is not present
844        - fixed orphaned pointers when setting maximum voices limit (bug #118)
845        - fixed crash when changing the audio output device of a sampler
846          channel with loaded instrument and start playing notes
847        - fixed endless loop in Engine::SuspendAll() (bug #120)
848        - fixed a low-level atomic load function that was broken on 64-bit
849          PowerPC, which probably could cause crashes on that platform
850        - fixed a memory management error which could cause a crash when a
851          plugin was unloaded
852        - bugfix: two private structs had the same name, which could cause
853          problems if the linker chose the wrong constructor
854        - fixed low-level ConditionServer usage bug that caused lockups on
855          Windows
856    
857    
858    Version 0.5.1 (6 December 2007)
859    
860      * packaging changes:
861        - added autoconf checks for pthread library
862        - added autoconf check for pthread bug found on certain NPTL-enabled
863          glibc versions (see Gentoo bug report #194076)
864        - added autoconf checks for MS Windows
865    
866      * general changes:
867        - bugfix: the thread used by an editor plugin didn't die when the
868          editor closed
869        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
870          out all the space. operator--() did not apply size_mask after
871          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
872          order to avoid problems with the _NonVolatileReader functions.
873        - bugfix: Stream.h: added a missing divide by BytesPerSample in
874          GetWriteSpace(). Since this function is currently only used in
875          the stream's qsort() compare function, it didn't trigger any
876          bugs.
877        - Resampler.h, Synthesizer.h: cubic interpolation now works in
878          24bit mode too. Faster method to read 24bit words on little
879          endian machines (x86): replaced 3 byte reads + shifts with a 1
880          unaligned 32bit read and shift
881        - experimental support for MS Windows (MIDI input via MME, AUDIO
882          output via ASIO)
883        - made handling of SIGINT signal (Ctrl-C) a bit more robust
884        - support for monitoring the total number of active disk streams
885          (new LSCP commands: GET TOTAL_STREAM_COUNT,
886          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
887    
888      * AUDIO driver:
889        - added Windows ASIO low latency audio driver
890    
891      * MIDI driver:
892        - added MME Windows MIDI driver
893    
894      * LSCP server:
895        - added support for Windows style path / filenames, however with
896          forward slash path separators instead of backslash
897          (i.e. "C:/foo/bar.gig")
898        - allow naughty liblscp to send non-string device parameters within
899          apostrophes as well
900        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
901          "LIST FILE INSTRUMENTS <file>" and
902          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
903          about an arbitrary instrument file on the system where the sampler is
904          running on
905    
906    Version 0.5.0 (15 October 2007)
907    
908    * packaging changes:    * packaging changes:
909        - config.h is not going to be installed along with liblinuxsampler's
910          API header files anymore
911        - only the API relevant header (and source) files will be exported to
912          the Doxygen API documentation (explicitly listed in Doxyfile.in)
913        - added completely new XCode project files for Mac OSX which is now
914          capable to execute our autoconf environment, thus no need anymore
915          to maintain the compile time configuration file (osx/version.h) for
916          OSX manually (patch by Toshi Nagata)
917        - fixed buggy boolean --enable-foo / --disable-foo configure script
918          parameters
919        - global.h now only covers global definitions that are needed for the
920          C++ API header files, all implementation internal global definitions
921          are now in global_private.h
922        - atomic.h is not exposed to the C++ API anymore
923        - no need to include config.h anymore for using LS's API header files
924        - fixed warnings in API doc generation
925    
926      * general changes:
927        - replaced the old, confusing MIDI program change mechanism by a
928          flexible MIDI instrument mapper which allows to map arbitrary
929          (MIDI bank, MIDI program) pairs with arbitrary
930          (engine type, instrument file, file index) triplets which will be
931          loaded on the respective channel when such MIDI program change
932          messages arrive, beside that, each entry allows to define a life-time
933          strategy for the instrument, so the user can define whether the
934          instrument should i.e. be permanently loaded (to be able to switch
935          quickly among sounds) or i.e. loaded just on demand when the
936          respective program change arrives (to safe RAM space), as well as a
937          global volume factor for each entry, so the user can adjust the volume
938          dynamic of his mapped instrument collection without having to modify
939          the instrument files, also one can manage arbitrary amount of such
940          MIDI instrument maps and assign each sampler channel individually
941          a certain map, so that i.e. separation of normal instruments and
942          drumkits is possible
943        - new notification events for tracking changes to audio/MIDI devices,
944          MIDI instrument maps, MIDI instruments, FX sends, global volume.
945        - sampler was limited to load max. 200 instruments in the background
946          due to a constant size RingBuffer FIFO which is now replaced by a
947          dynamic (unlimited) size std::list FIFO
948        - added FX sends, these allow to route audio signals to arbitrary audio
949          output channels for being processed by external effect processors
950          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
951          controllers
952        - global (sampler wide) volume can now be controlled at runtime
953        - Implemented new, improved notification system
954        - fixed compilation errors regarding OSX
955          (patch by Toshi Nagata)
956        - implemented instruments database
957        - added support for escape sequences to the instruments database
958        - added highly experimental support for on-the-fly instrument editing
959          within the sampler's process (by using instrument editor plugins),
960          you'll notice the new "Registered instrument editors:" message on
961          startup, added a new LSCP command:
962          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
963          to spawn a matching instrument editor for the instrument on the
964          given sampler channel, the plugin path can be overridden at compile
965          time with ./configure --enable-plugin-dir=/some/dir
966        - added experimental code for synchronizing instrument editors hosted
967          in the sampler's process to safely edit instruments while playing
968          without a crash (hopefully) by either suspending single regions
969          wherever possible or if unavoidable whole engine(s)
970        - fixed several issues in fundamental "Thread" class: set scheduling
971          policy and priority on thread level, set a minimum stack size for
972          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
973          threads simply inherited properties of starting thread instead of
974          setting their own policy and priority
975        - minor fix in our automatic stack trace mechanism on crashes, the
976          main process did not wait for the stack trace process to finish
977          its output
978        - fixed some minor memory leaks
979        - reenabled assembly features support, at the moment only for
980          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
981        - minor assembly fix in x86 features detection (don't use the PIC
982          register, to avoid relocations in the text segment at runtime)
983        - POSIX callback functions of Thread.h are hidden
984    
985      * MIDI driver:
986        - dispatch bank select (MSB and LSB) messages
987    
988      * audio driver:
989        - the ALSA audio output driver parameters now reflect the correct
990          parameter value ranges for the respective selected sound card
991          (patch by Till Wimmer, a bit fixed and extended)
992    
993      * Gigasampler format engine:
994        - if a filter is used and EG2 finishes before EG1, let the voice
995          die when EG2 has finished (this fixes a problem with clicks and
996          voice starvation for some gigs)
997        - playback is no longer disabled during instrument loading
998        - all notes playing on a channel that changes its instrument keep
999          playing with the old instrument until they get a note off
1000          command
1001        - EG fix: a release value of zero could cause noises or crash
1002        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1003        - EG fine tuning: when attack is zero the EG starts at a level
1004          above max sustain level, which means that there is a decay phase
1005          even if sustain is 100%
1006        - more EG fixes: the level could sometimes go below zero and cause
1007          noises or crashes
1008        - minor fix of EGDecay (patch by Toshi Nagata)
1009        - fixed compiler error when --enable-override-filter-type was
1010          supplied to the configure script (fixes #46)
1011        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1012          instead of a fix value
1013        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1014          127 (solo mode) only kill voices if the respective mode really
1015          changed
1016    
1017      * LSCP server:
1018        - fixed compile time error for old Bison versions
1019          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1020        - parser now supports extended ASCII character set
1021          (up to ASCII code 255, i.e. includes now umlauts and accents)
1022        - filename arguments in LSCP commands now allow to use escape
1023          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1024          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1025          code value like \xf2) (fixes bug #24)
1026        - the following LSCP commands now also support escape sequences for at
1027          least one of their text-based parameters (i.e. name, description):
1028          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1029          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1030          "SET DB_INSTRUMENT_DIRECTORY NAME",
1031          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1032          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1033          "FIND DB_INSTRUMENT_DIRECTORIES"
1034        - returns verbose syntax errors (line and column where syntax error
1035          occured, the unexpected character and the actually expected, possible
1036          character(s), the latter only if less than 5 possibilities)
1037        - made sure that LSCP syntax is not affected by gigedit locale
1038          settings
1039        - bugfix regarding strings parameter lists: all comma separated lists
1040          of strings were treated as being one string containing commas
1041          (fixes #57)
1042    
1043      * Bug fixes:
1044        - fixed crash occurring on certain LSCP scripts (Bug 39)
1045        - another thread safety fix for lscp "load engine" and "set
1046          channel audio output device"
1047        - fixed a crash which occurs when reassigning the same engine
1048          on a sampler channel with connected MIDI device
1049        - fixed a crash which occurs when changing the number of ports of a MIDI
1050          device connected to a sampler channel to number less then or equal
1051          to the index of the port to which the sampler channel is connected.
1052        - The previous bindings were not been disconnected when altering
1053          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1054          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1055        - The active stream/voice count statistic was incorrect.
1056        - notification events were not been sent for some sampler
1057          channel changes
1058        - added default min and max values to restrict the number of allowed
1059          audio output channels and MIDI input ports
1060        - the connection to the PCM interface is now closed when destroying
1061          an audio output device
1062        - files with slash in their path or filename could not be loaded
1063    
1064      * test cases:
1065        - updated and fixed (haven't been touched in a while)
1066    
1067    Version 0.4.0 (24 November 2006)
1068    
1069      * packaging changes:
1070        - changed deprecated copyright attribute to license; added ldconfig
1071          to post-(un)install steps; added devel package for liblinuxsampler;
1072          to linuxsampler.spec (RPM)
1073      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party
1074        applications to link against liblinuxsampler        applications to link against liblinuxsampler
1075      - liblinuxsampler's API documentation can be generated with 'make docs'      - liblinuxsampler's API documentation can be generated with 'make docs'
1076        (Doxygen required)        (Doxygen required)
1077        - added benchmark to automatically detect the best triangle LFO
1078          implementation (currently either an integer math solution or a
1079          di-harmonic approximation), automatic detection can be overriden
1080          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1081          configure script argument though (mandatory for cross-compilation)
1082        - do not automatically pick optimized gcc flags if the user already
1083          provided some on his own (as CXXFLAGS)
1084        - added compile time option to disable processing of All-Notes-Off MIDI
1085          messages
1086        - added compile time options to allow disabling the various audio and
1087          MIDI drivers
1088        - fixed automatic GCC CPU switch detection on PPC
1089          (patch by Ebrahim Mayat)
1090    
1091    * Gigasampler format engine:    * Gigasampler format engine:
1092        - extensive synthesis optimization
1093          (reimplementation of EGs and LFO(s), removed synthesis parameter
1094          prerendering and the synthesis parameter matrix in general, splitting
1095          each audio fragment into subfragments now where each subfragment uses
1096          constant pitch and filter coefficients. The volume coefficient is
1097          linearly interpolated inside a subfragment, unless
1098          --disable-interpolate-volume is set.)
1099      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
1100        - improved filter cutoff calculation by adding support for the
1101          following gig parameters: Cutoff freq (used when no cutoff
1102          controller is defined), Control invert, Minimum cutoff, Velocity
1103          curve and Velocity range. The keyboard tracking now scales
1104          cutoff frequency instead of resonance.
1105        - added support for gig parameter Resonance.
1106        - fixed bug in sysex handling (patch by Juan Linietsky)
1107        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1108          which can be overridden with --enable-global-attenuation
1109        - EG fixes: made the length of "attack hold" stage more
1110          accurate. Release stage can now start before attack stage
1111          ends. Cancel release didn't work when sustain was zero. Attack
1112          time now has a minimal value to prevent clicks.
1113        - fixed pitch changes larger than one octave
1114        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1115        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1116          all modes can be altered via standard GM messages, that is CC5 for
1117          altering portamento time, CC65 for enabling / disabling portamento
1118          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1119        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1120          parameter) and crossfade
1121        - added support for the "attenuation controller threshold" gig
1122          parameter
1123        - added smoothing of volume changes caused by control change
1124          messages
1125        - sample loop parameters are now taken from the DimensionRegion
1126          instead of the wave chunk
1127        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1128          not equal to a power of two
1129        - reimplementation of the filter algorithm. The new filter is more
1130          accurate and supports all gig filter types, including bandreject
1131          and lowpass turbo.
1132        - real support for 24 bit samples - samples are not truncated to
1133          16 bits anymore
1134        - support for aftertouch (channel pressure, not polyphonic
1135          aftertouch)
1136        - LFO1 behaviour fixed (dampening from max volume instead of
1137          amplifying from 0)
1138    
1139    * LSCP server:    * LSCP server:
1140      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
1141        - fixed the notification messages delay due to lack of
1142          network activity (fixes bug #26)
1143        - fixed parser bug which occured on space(s) within device parameters
1144          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1145    
1146      * audio driver:
1147        - added aRts audio output driver (by no means RT safe)
1148    
1149      * MIDI driver:
1150        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1151          messages several times instead of once
1152        - API extension for MIDI drivers which already supply exact time stamps
1153          for events (i.e. for offline rendering based MIDI drivers)
1154        - added checks for bad MIDI data
1155    
1156      * linuxsampler application:
1157        - show available sampler engine types on startup
1158    
1159    * general changes:    * general changes:
1160      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new
1161        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1162        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1163        introduced for this, the behavior is the same like on a mixer console        introduced for this, the behavior is the same like on a mixer console
1164        (patch by Grigor Iliev, a bit adjusted)        (patch by Grigor Iliev, a bit adjusted). Also added configure option
1165          --enable-process-muted-channels which can be used to enable the
1166          processing of muted channels.
1167        - support for sostenuto pedal
1168        - support for monitoring the total number of active voices
1169          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1170          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1171        - fixed some memory management errors
1172        - fixed some concurrency problems that could lead to crashes when
1173          LSCP commands were executed
1174        - fixed crash when instrument loading failed previously on the same
1175          sampler channel (fixes bug #36)
